THE POPULAR SCIENCE MONTHLY. MAY, 1885. OUK KECENT DEBTS TO VIVISECTION.* Br WILLIAM W. KEEN, M. D. PROFESSOR OF SURGERY. LADIES : It is my happy privilege to congratulate you on the com- pletion of your three years of preliminary study, and on your merited reward in receiving the degree of Doctor of Medicine from the oldest and largest medical college for women in the world. By this degree you are permitted to enter the ranks of one of the most ancient, honorable, and laborious professions. With it you as- sume certain valued privileges, and have cast upon you certain weighty duties. Both the privileges and the duties will exact from you all the intelligence, skill, tact, and faithfulness which you possess. You will observe that I said a moment since you had finished your "preliminary" studies; for your first and most pressing duty after graduation, and one for which happily you will at first have ample time, is to continue your medical studies. I do not say complete them, for, be your lives even prolonged far past the allotted threescore and ten, instant, constant, intense study is the imperative condition of the right kind of success. You know very little now. Happy both you and your patients, if even writh gray hairs comes ever-growing knowledge. But you have other duties than those to self — you have great duties to the communities in which you wTill live. Women especially will not only look to you in times of peril, whether in childbirth or sickness or accident, but also for guidance in that greatest duty and privilege — the prevention rather than the cure of disease. This is the glory of our times and the magnificent duty of our profession, that by enlightened * The Address to the graduates of the Woman's Medical College of Pennsylvania, Philadelphia, delivered March 11, 18S5. vol. xxvii. — 1 2 THE POPULAR SCIENCE MONTHLY. care and wise instruction we can prevent much of the sickness and sorrow of the race, and bid back the Angel of Death. Hygiene — well named after Hygeia, the goddess of good health- must be one of your principal future studies, and its lessons ever on your lips ; line upon line, precept upon precept, here a little, and there a great deal. The greatest need of our College to-day is a Professor- ship of Hygiene. Would that in this vast audience some one could be found who would endow such a chair in the Woman's Medical Col- lege of Pennsylvania ! You must also direct public opinion, and especially the opinion of your own sex, in reference to medical questions ; for your information and studies will fit you to be their instructors in all such technical questions. It is to one of these medical issues of the day that I purpose to direct your attention at present — one as to which intense feeling, espe- cially among women, has been aroused — viz., the question of experi- ments upon animals. Epithets and invective have been freely used, but, as befits the audi- ence and the occasion, I shall endeavor to approach it in a perfectly calm and fair spirit, seeking to lay before you only one aspect of a many-sided question, viz., the actual practical benefits it has conferred upon man and animals — a fact that is constantly denied, but which medical evidence proves to be incontestable. I shall not consider the important older discoveries it has given us, but only those since 1850, almost all of which are within my own per- sonal recollection. Even of these I must omit nearly all of its con- tributions to physiology and to pathology, though so much of our practice is based upon these, and confine myself to the advances it has enabled us to make in medical and surgical practice. I shall endeavor to state its claims with moderation, for an extravagant claim always produces a revulsion against the claimant, and is as unwise as it is unscientific. Again, it must be borne in mind that, as in nearly every other ad- vance in civilization and in society, so in medicine, causes are rarely single, but generally multiple and interwoven. While vivisection has been a most potent factor in medical progress, it is only one of several factors the disentanglement of which and the exact balancing of how much is due to this or to that are often difficult and sometimes impos- sible. Let me add one word more. All that I may say is purely upon my own responsibility. I commit the opinion of no one else to any view or any statement of fact. Medicine in the future must either grow worse, stand still, or grow better. To grow worse, we must forget our present knowledge — happily, an inconceivable idea. OUR RECENT DEBTS TO VIVISECTION. 3 To stand still, we must accept our present knowledge as a finality, complacently pursuing the well-worn paths ; neither hoping nor trying for anything better— happily, again, an impossibility. To grow better, we must try new methods, give new drugs, per- form new operations, or perform old ones in new ways ; that is to say, we must make experiments. To these experiments there must be a beginning : they must be tried first on some living body; for it is often forgotten that the dead body can only teach manual dexterity. They must then be tried either on an animal or on you. Which shall it be ? In many cases, of course, which involve little or no risk to life or health, it is perfectly legitimate to test probable improvements on man first, although one of the gravest and most frequent charges made against us doctors is that we are experimenting upon our pa- tients. But in many cases they involve great risk to life or health. Here they can not, nay, they must not, be tested first upon man. Must we, then, absolutely forego them, no matter how much of promise for life and health and happiness they possess ? If not, the only alternative we have is to try them on the lower animals, and we would be most unwise, nay, more, we would be cruel, cruel both to man and to animals, if we refused to pain or even to slay a few animals, that thousands, both of men and of animals, might live. Who would think it right to put a few drops of the hydrochlorate of cocaine (a year ago almost an unknown drug) into the eye of a man, not knowing what frightful inflammation or even loss of sight might follow ? Had one dared to do it, and had the result been disastrous, would not the law have held him guilty and punished him severely, and all of us said Amen ? But so did Christison with Calabar bean, and well-nigh lost his own life. So did Toynbee with prussic acid on himself, and was found dead in his laboratory.* Accordingly, Roller, * I add the following striking extract from a speech in defense of vivisection, on April 4, 1883, by Sir Lyon Playfair, deputy Speaker of the House of Commons — no mean authority. The italics are my own : " For myself, although formerly a professor of chemistry in the greatest medical school of this country, I am only responsible for the death of two rabbits by poison, and I ask the attention of the House to the case as a strong justification for experiments on animals, and yet I should have been treated as a criminal under the present act had it then existed. Sir James Simpson, who introduced chloroform — that great alleviator of animal suffering — was then alive and in constant quest of new anaesthetics. He came to my laboratory one day to see if I had any new substances likely to suit his purpose. I showed him a liquid which had just been discovered by one of my assistants, and Sir James Simpson, who was bold to rashness in experimenting on himself, desired immedi- ately to inhale it in my private room. I refused to give him any of the liquid unless it was first tried upon rabbits. Two rabbits were accordingly made to inhale it ; they quickly passed into anaesthesia and apparently as quickly recovered, but from an after- action of the poison they both died a few hours afterward. Now, was not this a justifi- able experiment upon animals ? Was not the sacrifice of two rabbits north saving the life of the most distinguished physician of his time? . . . Would that an experiment of a like 4 THE POPULAR SCIENCE MONTHLY. of Vienna, properly and wisely tried cocaine first on animals,* and then, finding its beneficial effects, tried it upon man with like results, and one of the most remarkable drugs of modern times was thus made available. We are only on the threshold of its usefulness. It has been used in the eye, the ear, the nose, the mouth, the larynx and all other mucous membranes, in the removal of tumors, and as an internal medicine. When its physiological action has been still more thor- oughly and systematically investigated, its poisonous dose ascertained, when we know how it works, what its effects are upon the blood-press- ure, the heart, the nerves, the blood-vessels — effects that can not be accurately studied upon man — its usefulness may be increased to an extent as yet but little dreamed of. Should it only soothe the last painful hours of our great hero, General Grant, a nation will bless it and the experiments which gave it effect. Moreover, had the experi- ments of Dr. Isaac Ott, of Easton, f on this very drug, borne their due fruit, America would have had the honor and the human race the bene- fits of cocaine ten years ago — ten years of needless suffering ! This is but one illustration of the value of experiments upon ani- mals in the realm of new drugs. In fact, substitute for eocaine other drugs, or new operations, or new methods of medical treatment, and the argument repeats itself for each. Within the last thirty years a multitude of new drugs have thus been discovered, and their effects have been either first tested upon animals, or their properties studied exhaustively in a manner impracticable upon man. I will only enu- merate some of them, since time will not allow me to enter upon each in detail. Thus have been introduced lily-of-the-valley in heart-disease, yellow jasmine, in diseases of the heart and nervous system, paralde- hyde and chloral-hydrate, so valuable for sleep, caffeine for headache, eucalyptus as an antiseptic and in medicine, nitro-glycerine for nervous maladies, Calabar bean for diseases of the eye and nervous system, naphthaline and iodoform in surgery, quebracho as an antispasmodic, antipyrin and kairin in fever, jaborandi in dropsy, salicylic acid in rheumatism, nitrite of amyl in epilepsy and intermittent fever, jequir- kind on a rabbit or a Guinea-pig bad been used by Jobn Hunter, wbo probably shortened his own noble life by experimenting on himself! . . . " Let me give one other instance. ... A few years ago two young German chemists were assistants in a London laboratory. They were experimenting upon a poison which I will not even name, for its properties are so terrible. It is postponed in its action, and then produces idiocy or death. A experiment on a mouse or a rabbit would have taught them the danger of this frightful poieon ; but, in ignorance of its subtle properties, they became its unhappy victims, for one died and the other suffered intellectual death. Yet the promoters of this bill would not suffer us to make any experiments on the lower ani- mals so as to protect man from such catastrophes. It is by experiments on animals that medicine has learned the benefits, but also has been taught to avoid the dangers of many potent drugs — as chloroform, chloral, and morphia." * " Archives of Ophthalmology," September and December, 1884, p. 402, New York, Putnams. f Ott, "Cocai'n, Veratrin, and Gclsemium," Philadelphia, 1874. OUR RECENT DEBTS TO VIVISECTION. 5 ity in ophthalmic surgery, piscidia as a substitute for opium, the hypo- dermic method of using drugs, and so on through a long list. And, as to the old drugs, it may be truly said that we have little exact, that is scientific, knowledge of any one except through experiments upon animals;* Let us see now something of what America has done in advancing practical medicine by vivisection. In passing, I may say that the assertion that America has contributed but little, so far from being an argument for the restriction of vivisection, is a strong argument for its further cultivation, in order that greater good may result from remarkable discoveries here, equal to those that I shall show have been made in Europe. Wounds of the abdomen, especially gunshot-wounds, are among the most fatal injuries known to surgery. A small, innocent-looking, external pistol-wound may cover multiple and almost inevitably fatal perforations of the abdominal contents. The recoveries from 3,717 such wounds during the late civil war only numbered 444, and of those with escape of the intestinal contents the recoveries, says Otis, may be counted on one's fingers. The prevailing treatment as laid down in our text-books has been purely conservative, treating symptoms as they arise. The brilliant results achieved in other abdominal opera- tions have led a few bold spirits, such as our own Sims, Gross, Otis, McGuire, and others, to advocate the opening of the abdomen and the repair of the injuries found. In May of last year, Parkes, of Chicago, reported to the American Medical Association f a series of systematic experiments on thirty-seven dogs, that were etherized, then shot, the abdomen opened, and the wounds of the intestines, arteries, mesentery, etc., treated by appro- priate surgical methods. The results confirmed the belief awakened by earlier experiments and observations that surgery could grapple successfully with multiple and formidable wounds, by sewing them up in various ways, or even by removing a piece of the bowel and uniting the cut ends. Hard upon the heels of this important paper, # For three hundred years digitalis, for instance, has been given as a depressant of the heart, and, when a student, I was taught to avoid it carefully when the heart was weak. But the accurate experiments of Bernard and others have shown that it is, on the contrary, actually a heart tonic and stimulant. So long as I live I shall never forget the intense joy of myself and the agonized parents, when one bright young life was brought back from the very grave, some five years ago, by the knowledge of this fact, and this is but one of many such cases. Thus have the action and dangers of our common anaesthet- ics been positively and accurately ascertained ; thus the action of ergot on the blood- vessels, explaining alike its danger as an article of food and its wonderful use in certain tumors of the uterus and diseases of the nervous centers ; thus, too, every one who gives opium in its various forms is a debtor to Bernard, and every one who gives strychnine a disciple of Magendic. f "Medical News," May 17, 1884. I shall refer readers frequently to this journal, as it is often more accessible than foreign journals, and it will refer them to the original papers. 6 THE POPULAR SCIENCE MONTHLY. and largely as its result, comes a striking improvement in practice. And remember, that this is only the first fruit of a rich harvest for future time, in all countries, in peace and in war. November 2d, of last year, a man was brought to the Chambers Street Hospital, in New York, with a pistol-shot wound in the abdo- men. Under careful antiseptic precautions, and following the indica- tions of Parkes, the abdomen was opened by Dr. Bull,* coil after coil of the intestines was drawn out, the bullet was found and removed, and seven wounds of the intestines were successively discovered and properly treated, and the patient made an uninterrupted recovery. A recovery, after so many wounds, any one of which would necessarily have been fatal under the old methods of treatment, shows that we have now entered upon a proper and successful method of treatment for such frightful accidents. This is but one of the remarkable achievements of late years in abdominal surgery. The spleen has been removed, part of the stom- ach has been cut out for cancer, part of the bladder has been dissected away, the entire gall-bladder has been removed, and several inches of the intestine have been cut out, all with the most remarkable success. To all of these, experiments upon animals have either led the way, or have taught us better methods. To recite each in detail would oc- cupy too much time, but one illustration I must not omit, for the improvement, produced by it and other experiments, affects every abdominal operation. When I was a student, the peritoneum was avoided by knife and needle wherever possible. After the death of his fourth case of ovariotomy, Mr. (now Sir Spencer) "Wells, f in making the post-mortem, was led to believe that the then received treatment of the peritonaeum was incorrect, and that he ought to bring its sur- faces in contact in order to obtain secure union. Accordingly, instead of testing his ideas upon women, he experimented upon a few dogs, and found that his suspicions were correct. Since then it has been accepted as a cardinal point in all abdominal operations. Following this came improvements in the ligatures used, in the method of treat- ing the pedicle, in the use of antiseptics, etc., all more or less the result of experiments upon animals, and what are the results ? Tak- ing successive hundreds of cases, Sir Spencer Wells's percentage of mortality has decreased steadily from thirty-four per cent to eleven per cent. In 1,000 operations he has saved 7G9 women from the grave and added a net gain of 17,880 years to human life, to say nothing of the happiness of the thousands related to them by ties of friendship and of blood — a proud boast indeed ! Since then, others have reduced the percentage of deaths after ovariotomy to three in the hundred ; and Martin, of Berlin, has lost but one patient from blood-poisoning in his last 130 cases. * " Medical News," February 14, 18S5. f Wells, "Ovarian and Uterine Tumors;' 1982, p. 197. OUR RECENT DEBTS TO VIVISECTION. 7 It can not be claimed, of course, as to all this wonderful history of abdominal surgery — and remember that in 18G2, when I was a medical student, I heard ovariotomists denounced from a professor's chair as murderers ! — that experiments upon animals have done the whole work. No one man, no one series of experiments has sufficed, and experiment alone would not have done it. But had such experiments not been made on animals, as to the peritoneum, the pedicle, the su- tures, the ligatures, etc., we should be far behind where we now are, and still be ignorantly sacrificing human life and causing human suf- fering. But to return to America. The first condition to successful treat- ment is an accurate knowledge of what any disease is — its cause and its course — then we may guide it, and in due time, it may be, cure it. Before Dr. H. C. Wood's* accurate experiments on the effects of heat on animals, the nature and effects of sunstroke were almost mat- ters of mere conjecture. Every one had his own theory, and the treat- ment was equally varied. Even the heat-effects of fever itself — the commonest of all symptoms of disease — were ill understood. Wood exposed animals to temperatures of 120° to 130° Fahr. and studied the effects. These experiments have often been alluded to as "baking animals alive." You will note that the heat was no greater than that to which laborers are frequently exposed in our hot summer-days, when working in the sun or in many industrial works. His experi- ments showed that the effects of sunstroke — or, as he happily termed it, Thermic or heat fever, a scientific name now widely adopted — were solely due to the heat, death following from coagulation of the muscu- lar structure of the heart, or by its effects on the brain. They ex- plained also many of the phenomena of ordinary fever as the result of heat alone. They have established the rational and now generally- adopted treatment of sunstroke by reduction of the body-tempera- ture ; and the same method is now beginning to be appreciated and employed in ordinary fever, f The same observer, with Dr. Formad, has made important experi- ments on the nature of diphtheria, and when we learn, as we probably soon shall, how to deal with the microscopic forms of life which seem to be its cause, it will not be too much to hope that we may be able to cope far more successfully with a disease now desolating so many homes. In India alone twenty thousand human beings die annually from snake-bite, \ and as yet no antidote has been discovered. How can we * Wood, "Thermic Fever or Sunstroke," Philadelphia, 18*72. f Eighteen out of Wood's experiments were on the general effects of heat, as above alluded to. In six others the local effects of heat (135° to 190° Fahr.) on the brain, and in four others the local effects (up to 140° Fahr.) on the nerves were studied, and gave most valuable results, entirely and evidently unattainable on man. % Fayrer, " Thanatophidia of India," p. 32. 8 THE POPULAR SCIENCE MONTHLY. search intelligently for an antidote until we know accurately the effects of the poison ? This can not be studied on man ; we must resort to animals, 01* else let the holocaust go on. Accordingly, Dr. T. Lauder Brunton began such a series of experiments in London, but was stopped by the stringent anti-vivisection laws there in force. But Drs. Weir Mitchell and Reichert,* in this city, have recently undertaken experiments on cobra and rattlesnake venom, the cobra-poison being furnished, be it observed, by the British Government, whose own laws have prevented investigations for the benefit of its own subjects ! The results are as yet only partly made known, but they have been brill- iantly successful in showing that there are two poisons in such venom, each of which has been isolated and its effects studied. The first step has been taken — the poison is known. Who will raise a finger to stop progress toward the second — the antidote ? Can the sacrifice of a few score of animals each year in such research weigh for a moment against the continuous annual sacrifice of twenty thousand human beings ? f The modern history of anaesthetics is also of interest. To say nothing of ether and chloroform, whose safer use Bert has investi- gated in France, nor of cocaine, to which I have already alluded, let us see what experiments on animals have shown us as to bromide of ethyl — an anaesthetic lately revived in surgery. Its revival has quickly been followed by its abandonment on account of the frequent sacrifice of human life — that is to say, experiments on human beings have proved it to be deadly. Now, Dr. II. C Wood, J soon after its ^intro- duction, made a study of its effects on animals, and showed its physio- logical dangers. Had his warnings been heeded, not a few human lives would have been saved. The ideal anaesthetic, that will abolish pain without abolishing con- sciousness, and do so without danger, is yet to be found. Cocaine is our nearest approach to it. Now, in all fairness and common sense, would it be real kindness or real cruelty to obstruct the search for such an anaesthetic — a search which will surely be rewarded by suc- cess, but which, if not carried on by experiments on animals, must be * "Medical News," April 28, 1883. f I am permitted by Rev. It. M. Luther, of this city, to state the following fact in illustration of the practical value of vivisection in snake-bite : When a missionary in Burmah, he and his brother-in-law, Rev. Mr. Vinton (two missionary vivisectionists !), made a number of experiments to discover an antidote to the poison of the "brown viper" — a snake but little less venomous than the cobra. They found a substance which is an antidote in about sixty per cent of the cases if applied at once. Thah Mway, one of their native preachers, when bitten by the brown viper, had some of this antidote with him, and by its use his life was saved when on the verge of death. This one life saved has been the means of leading, it is estimated, two thousand Karens to embrace Christianity. Was not this one life worth all the dogs used in the experiments — to make no mention of the many other lives that will be saved in all the future ? X "Philadelphia Medical Times," April 24, 1880. OUR RECENT DEBTS TO VIVISECTION. 9 tried by deadly experiments upon man, or else be hopelessly given up? In 1869 I was called to see a man suffering to the last degree from an abscess in the loin. I recognized the fact that it arose from the kidney, but I was powerless. All that I could do was to mitigate, and that, alas ! but little, his pitiless sufferings till death came to his relief, after nearly a year of untold agony. I have never forgotten his suf- ferings, nor the sharp pain 1 felt when I learned, two years later, how I might possibly have saved his life. In the very same year (1869), Simon, of Heidelberg,* had a woman under his care suffering from urinary fistulae from a healthy kidney — a surgical accident he in vain tried to heal. That she could live with one kidney had the other gradually been disabled by disease was probable, for one such diseased kidney had been already removed three times when mistaken for ovarian disease ; and physiologists had often removed one or both kidneys in animals. But no one had removed a healthy kidney, and then studied the effects on the remaining kidney and upon the heart ; no one had tested what was the best method of reaching the kidney, whether by the abdomen or the loin, or how to deal with its capsule, or the hemorrhage, or the surgical after-effects. Of course, Simon could have tried the experiment on his patient, blindly trusting to Providence for the result. But he chose the wiser course. He studied the previous literature, experimented on a number of dogs and watched the points above noted, tried various methods of operating upon the dead body, and, after weighing all the pros and cons, deliberately cut down upon the kidney of his patient after a carefully formulated plan, not by the abdomen, but through the loin, and saved her life. She died in 1877, after eight years of healthy life, free from her loath- some disorder. Now, what have been the results of these experiments upon a few dogs ? One hundred and ninety-eight times the kidney has been re- moved, and 105 human lives have been saved ; 83 times abscesses in the kidney have been opened, and 66 lives saved ; 17 times stones have been removed from the kidney without a single death — or, in all, in the last fifteen years, 298 operations, and 188 human lives saved. Besides this, as an extension of the operation in 17 cases, in which the kidney, having no such attachments as ought to anchor it in place, was floating loosely in the abdomen and a source of severe pain, it has been cut down upon and sewed fast in its proper place ; and all of these patients but one recovered. Looking to the future, when not hundreds but thousands of hu- man beings will enjoy the benefits of these operations, and in increasing percentages of recoveries, are not the sufferings inflicted on these few dogs amply justified as in the highest sense kind and humane ? f * Simon, "Cbirurgie der Niercn," 1871, preface. f Very erroneous views prevail as to the sufferings of animals from experiments upon io THE POPULAR SCIENCE MONTHLY. Not long since Dr. Ferrier, of London, was prosecuted for the alleged performance of certain experiments on the brains of the lower animals. With Fritsch, Hitzig, Goltz, Yeo, and others, he had de- stroyed or galvanized certain limited areas of the brain (and it must not be forgotten that the brain is wholly without the sense of pain), and so determined the exact nervous centers for certain limited groups of muscles. As a result of their labors, the brain is now mapped out with reasonable accuracy, so that, given certain hitherto ill-understood or obscure localized symptoms, we can now say that there is certainly a tumor, an abscess, or other disease in precisely this or that locality. True, we can doubtfully infer somewhat of the same from the cruel experiments of disease on man. But Nature's experiments are rarely ever limited in area or uncomplicated ; they are never systematic and exhaustive ; it takes years to collect a fair number of her clumsy ex- periments, and the knowledge is diffused through many minds instead of being centered in one that will systematize the results. Said Ferrier, a year ago, in the Marshall Hall oration, " There are already signs that we are within measurable distance of the successful treatment by surgery of some of the most distressing and otherwise hopeless forms of intra-cranial disease, which will vie with the splen- did achievements of abdominal surgery." Note the fulfillment ! Last fall, within a year of the foregoing prophecy, a man, aged twenty-five, entered the London Hospital for Epilepsy and Paralysis.* From the symptoms, which I need not de- tail, Dr. Hughes Bennett, basing his conclusions on Ferrier's experi- ments, diagnosticated a tumor of small size on the surface of the brain, involving the center of motion for the muscles of the hand. On November 15, 1884, at his instance, Mr. Godlee trephined the skull over the selected spot, and a quarter of an inch below the surface of the brain found a tumor as big as a walnut, and removed it. For three weeks the man did well, but died on the twenty-eighth day from blood-poisoning, such as might follow any operation, especially a new one. Macewen, of Glasgow, f has similarly trephined a woman, the vic- tim of slow paralysis of body and mind, and opened an abscess a little distance below the surface, letting out two teaspoonfuls of pus, and followed by entire mental and physical recovery. them. Many persons suppose that " vivisection " means deliberate " cutting up " of an animal, little by little, till not enough is left to live. So far is this from the truth, that Professor Gerald Yeo, from the actual reports of vivisectionists in England ("Fortnightly Review, March, 1SS2), estimates that of one hundred such experiments, there are: Absolutely painless *15 As painful as vaccination 20 As painful as the healing of a wound 4 As painful as a surgical operation 1 Total 100 * " Medical News," January 17, 1885. \ Ibid., January 3, 1SS5. OUR RECENT DEBTS TO VIVISECTION. n By these experiments and operations a wide door is open to sur- gery in the treatment of diseases within the skull — diseases heretofore so obscure and uncertain that we have hardly dared to attack them. The question is not whether death or recovery followed in these par- ticular cases. The great, the startling, the encouraging fact is that, thanks to these experiments, we can now, with well-nigh absolute cer- tainty, diagnosticate, and with the greatest accuracy locate such dis- eases, and therefore reach them by operation, and treat them success- fully. Would that I had been born twenty-five years later, that I might enjoy with you the full luxury of such magnilicent life-saving, health-giving discoveries ! It is, however, by the experimental study of the effects of minute organisms — microbes, as they are now called — that some of the latest and most remarkable results have been achieved. The labors of Koch, Pasteur, Klein, Cheyne, Tommasi-Crudeli, Wood, Formad, Sternberg, and others, are now known even to the daily press. Let us see what they have done. It is but three years since Koch announced that consumption was caused by the " bacillus tuberculosis." Later he has studied cholera and found the "comma-bacillus," to which he ascribes that dreaded disease. In spite of the opposition of prominent scientists, his views have been in general accepted, and seem to be reasonable. The method of experiment is simple, though difficult. The sus- pected expectoration or discharge is placed in a suitable soil, and after cultivation some of this growth is placed in another culture-soil, and so on till generation after generation is produced, the violence of the poison being modified by each culture. A small portion of any one of these cultures is then injected under the skin of a mouse or other ani- mal, and in time it dies or is killed, and the results are verified by the post-mortem. So exact is the knowledge in tuberculosis now that Koch can pre- dict almost to an hour when the mouse will die of consumption, or that it will escape, according to the culture used. It is far too early as yet to say that these studies have borne the immense practical fruit that the next few years will show ; but they have already enabled us to recognize by the microscope doubtful cases of consumption in their earlier and more remediable stages, and have made certain what has hitherto been only a probability — that consump- tion is distinctly contagious. By Gerlach's experiments on animals with the milk from tuber- cular cows, also, it has been shown that consumption may be con- tracted from such milk. How important this conclusion is, in so universal an article of food to young and old, I need not do aught than state. The experiments of Wood and Formad on diphtheria I have already alluded to. Those of Tommasi-Crudeli also have shown that probably 12 THE POPULAR SCIENCE MONTHLY. the poison of malaria is due to like organisms, while a large number of other diseases are being similarly investigated. As to cholera, the classic experiments of Thiersch, in 1853, * are well known. He inoculated fifty-six mice with cholera-discharges. Of these, forty-four sickened and fourteen died from choleraic diseases. In the same year two water companies in London experimented on 500,000 human beings, one of them inoculating its patrons with chol- era-discharges through its impure water-supply. This one sickened thousands and killed 3,476 human beings, most of whom might have escaped had the lessons of Thiersch's fourteen mice been heeded. To ask the question, which was the more cruel, is to answer it. f At present our strenuous efforts are all in one direction — viz., to study these microbes by the microscope, by clinical observation, and by experiments on animals, in order to find out their origin, causes, growth, and effects, and to discover by what means their deadly re- sults may be avoided, or by what remedies, without harm to the patient, they may themselves be destroyed. Evidently these studies can not be tried on our patients. They must either be tried on animals or be abandoned. The inoculation experiments of modern times have recently borne rich fruit in still another pestilential disease — yellow fever — whose ravages in this country are fresh in our minds. November 10, 1884, M. Bouley reported to the Paris Academy of Sciences J that, since 1880, M. Freire, of Rio Janeiro, had experimented on Guinea-pigs with the virus of yellow fever, and believed that he had been able to produce such attenuation of the virus that by vaccination he could secure im- munity from this dreadful scourge. Following the experiments, he and Rabourgeon tested the results on themselves, some students of medi- cine, and employes. Later the Emperor Dom Pedro authorized two hundred wharf-laborers to be inoculated. All these, after a three days' mild attack, remained free from the pestilence, while their fel- low-laborers, similarly exposed to the fever, were dying on every hand. If, in an epidemic, this still prove true, as there seems every proba- bility it will, from the five hundred lives already saved, we can hardly estimate either the medical or the commercial advantages to this coun- * John Simon, "Proceedings International Medical Congress," London, 1881. f The population supplied by the Southwark and Vauxhall Company, in the epidemic of 1818-'49, died at the rate of 118 in each 10,000, and, in that of 1853-'54, at the rate of 130 per 10,000. Those supplied by the Lambeth Company died in 1848-'49 at the rate of 125 per 10,000, but having improved its water supply meantime, the death-rate, in lS53-'54, fell to 37 per 10,000. If Thiersch lived in England to-day, he would have to take out a license to kill his fourteen mice in the interests of humanity — a license possibly refused, or only to be obtained after the most vexatious delays. But any house-maid might torture and kill them with arsenic or phosphorus, or Thiersch might give them to a favorite terrier with- out the slightest interference, provided only it be not for a scientific or a humane object! \ "Medical News," November 29, 18S4. OUR RECENT DEBTS TO VIVISECTION. 13 try alone. Is this cruelty ? Let Norfolk, and Memphis, and Pensa- cola, and New Orleans answer. We are all familiar now with the numerous deaths from eating pork infested with trichina. While I was in Berlin, in 1865-'66, a ter- rible epidemic of the then new disease broke out at Hedersleben, a small town in Prussian Saxony. I well remember with what zeal Vir- chow and his assistants immediately investigated the disease, inocu- • lated animals with the parasitic worm, studied its natural history, found out that heat killed it, and to-day, as a result of these and other experiments, we all know how to avert its dangers by proper cooking, or to avoid it altogether by the microscope. The value of these ex- periments, both to human life and to commerce, you know even from the daily papers. You will find it difficult to make the non-medical public understand — nay, you yourselves as yet hardly understand — the enormous ad- vance in medicine and surgery brought about by recent researches on inflammation, and by the use of antiseptics. My own professional life only covers twenty -three years, yet in that time I have seen our knowl- edge of inflammation wTholly changed, and the practice of surgery so revolutionized that what would have been impossible audacity in 1862 has become ordinary practice in 1885. It would seem that so old a process as inflammation would long ago have been known through and through, and that nothing new could be adduced. In 1851, however, Claude-Bernard, by a slight operation, divided the sympathetic nerve in a rabbit's neck and showed its influ- ence on the caliber of the blood-vessels. In 1858 Virchow published his " Cellular Pathology." In 1867 Cohnheim (Virchow's " Archiv ") published his studies on the part that the blood-cells played in inflam- mation as shown in the frog, followed by further papers by Dr. Nor- ris, of this city, Strieker, Von Recklinghausen, Waldeyer, and many others. Already in my lectures I have pointed out to you in detail the advances made by these studies, both in theory and practice. They have brought about an entire reinvestigation of disease, and given us wholly new knowledge as to abscesses, ulceration, gangrene, the or- ganization of clots in wounds, and after operations and ligature of blood-vessels for aneurism, as to thrombosis, and embolism, and paral- ysis, and apoplexy, and a score of other diseases through the diagnosis and treatment of which now runs the silver thread of knowledge in- stead of ignorance. With this the brilliant results of the antiseptic system have joined to give us a new surgery. Sir Joseph Lister, to whom we chiefly owe this knowledge, has done more to save hmnan life and diminish human suffering than any other man of the last fifty years. Had he only made practicable the use of animal ligatures, it would have been an untold boon, the value of which can only be appreciated by doctors ; but he has done far more, he has founded a new system of surgery. i4 THE POPULAR SCIENCE MONTHLY. We may reject the spray and carbolic acid, but the surgical world, regardless of details, with few exceptions follows the principles upon which his method is founded and humanity is the gainer, by the nearly total abolition of inflammation, suppuration, secondary haemorrhage, blood-poisoning, gangrene, and erysipelas, as sequels of accidents and operations ; by the practicable relief from suffering and death, by op- erations formerly impossible ; by rendering amputations and compound fractures safe and simple instead of deadly. Reflect on what each one of these brief but momentous statements means ! But we have by no means reached perfection. Lister himself, no tyro, but the great master, is still searching for further improvements. But when lately he desired to make some experiments on animals, still further to perfect our practice, so many obstructions were thrown in his way in England that he was driven to Toulouse to pursue his hu- mane researches. I had intended also to speak of many other practical benefits to man directly, but can only mention such important matters as the sur- gery of the thyroid gland, the seat of goitre ; the surgery of the lungs, part of which have been removed ; the surgery of the nerves, removal of the entire larynx, the remarkable researches of late years as to the periosteum in the reproduction of new bone after removal of dead or diseased bone ; Bernard's important observations as to diabetes ; Brown-Sequard"s experiments on epilepsy, the modern extraordinary advance in nearly all the diseases of the nervous system, and a number of other discoveries, as to all of which experiments upon animals have added largely to our knowledge, and therefore to our means of diminishing suffering and saving human life. For many of these, as well as for the most judicial discussion of the vivisec- tion question I have yet seen, I must refer you to that remark- able book, "Physiological Cruelty," written, not by a man, but a woman* I had also intended to refer in detail to the splendid results of vivi- section in relieving the sufferings of animals, and in preventing enor- mous pecuniary loss to man. We are only beginning to see that vivi- section is as humane to animal life and suffering as it is to human, and that for financial reasons as well as humane motives it is of the utmost importance to the State that such diseases as cattle-plague, splenic fever, chicken-cholera, swine-plague, and others, should be eradicated. Vivisection has shown us how this may be done, and has so conferred upon animals too the boon of life and health. For all this, however, I must refer you to the recent admirable lecture by Professor Robert Meade Smith, of the University of Pennsylvania.! One subject, however, is so recent and of such interest, both to man and animals, that I must not pass it over — I mean that justly- * Sec also the just issued " Life and Labors of Pasteur." \ Reprinted from the "Therapeutic Gazette," November, 1884.

Within the last three years Pasteur has announced that, by passing the virus through the monkey, he has been able to protect dogs from hydrophobia by vaccination with this weakened virus. The French Government recently appointed an eminent scientific commission to report on the alleged discovery. * Pasteur furnished them with 23 vac- cinated dogs. These 23, and 19 others unprotected, were all inoculated from rabid animals. Of the 19 unprotected, 14 died. Of the 23 pro- tected dogs, one died of diarrhoea, and all the others escaped. It* has yet to be tried on a man suffering from hydrophobia, but, should our reasonable hopes be realized, what a boon it will be ! With this brief summary of a few of tlie recent practical benefits from vivisection, I must close. I have given you only ascertained facts for your future use in the communities in which you may settle. They may assist you in forming public sentiment on a basis of fact, of reason, and of common sense. The sentiments of our own profession, so constantly and so conspicuously humane, are always against inflict- ing pain ; but if in yielding to sentiment we actually increase disease, and pain, and death, both among animals and men, our aversion to present pain is both unwise and actually cruel. In conclusion, let me wish you the greatest success in your profes- sional life, and the richest blessings of our kind heavenly Father. Farewell. -Oo<>~ CAN MAN BE MODIFIED BY SELECTION?! By W. K. BKOOKS. THE certainty and rapidity with which our domesticated animals and plants may be modified in any desired direction by selective breeding must be regarded as a reason for believing that, if it were possible to pursue the same course with man, the human race also might be rapidly improved in the same way. It is difficult to prove this, for we are almost entirely removed, by our control over Nature and by our artificial life, from the influence of natural selection ; and, as we can not dictate to men and women whom they shall marry, we can not bring about a union of those with the same congenital charac- teristics, or propagate for a number of generations a peculiarity which it is desirable to perpetuate and intensify. There is reason to fear that our freedom from the influence of natural selection may lead to the degeneration of the race unless some * "Medical News," August 30, 1884. \ Review of a paper by Alexander Graham Bell, read before the National Academy of Sciences, November 13, 1883, upon the "Formation of a Deaf Variety of the Human Race." 16 THE POPULAR SCIENCE MONTHLY. way to supply its place is discovered and adopted ; and the first step in this direction is to prove by actual experiment that the race can he modified by selection like any other species of organism. The researches of Professor Bell, which show that a race of deaf- mutes is actually growing up in the United States through an unfor- tunate application of the law of selection, therefore have a very great scientific value, which is entirely independent 'of the warning they give of a danger which threatens us. In the paper which is quoted above he renders the community an important service by pointing out this danger ; but it seems to me that the chief value of his work is not in this direct practical bearing, but in the convincing proof which he furnishes to show that the law of selection does place within our reach a powerful influence for the im- provement of our race, for, as soon as the truth is borne home to all men by facts like those which Professor Bell has brought together, some effective means of applying it to mankind will certainly be devised. Mankind will not submit to any direct interference with personal liberty ; but, if it is true that desirable characteristics can be perpetu- ated and developed by selection, indirect methods of influencing the choice of husbands and wives could undoubtedly be devised and em- ployed. If all the children which exhibit the desired peculiarity could be brought together as early as possible, and could be made to live to- gether during their youth, carefully guarded from the possibility of making acquaintance with any other children, and if this restriction could be continued through the period when acquaintances and friend- ships and attachments are most easily established, this would be a great step toward selective breeding ; for all the children with the desired peculiarity would become intimately acquainted with one another, while they would have few outside friendships. If, after the children had grown up and become scattered, they were encouraged to hold periodical reunions for promoting social intercourse between them in adult life, and if they were provided with newspapers and peri- odicals of their own, which should make a specialty :>f " personals " relating to them, giving a full account of their conventions and re- unions, and keeping their readers informed of all their movements, their employments, their marriages, deaths, etc., the chances of inter- marriage among them would be greatly increased. If they were taught to speak and think in a language of their own, and Avere furnished with a literature of their own in this language, they would be very effectively cut off from intercourse with outsiders, and would be compelled to look to their own numbers for their com- panions and acquaintances; and there can be no doubt that, if all these influences Avere employed together generation after generation, they would soon lead to the establishment of a race sharply marked off CAN MAN BE MODIFIED BY SELECTION? 17 from the rest of the world by the excessive development of the char- acteristic upon which the selection was based. If the selection were a wise one, the result would be to the benefit of mankind ; but the result would follow just as surely if an injurious peculiarity or a defect were made the basis of the selection, for a natural law produces its effect, whether it is applied wisely or un- wisely. Professor Bell points out that our system of educating the deaf brings all these influences to bear, and that the means which have been adopted by philanthropists and others from the noblest and purest motives to ameliorate the condition of the deaf and dumb are unfor- tunately the most complete and efficient methods which it is possible to employ for inducing deaf-mutes to marry deaf-mutes, and that it would be difficult to devise a more certain means for increasing the number of unfortunate persons with this infirmity, and for producing by selection a deaf variety of the human race. We separate them from other children as early in life as possible, taking them away from their homes and placing them by hundreds in institutions where they are isolated from early childhood to the com- mencement of adult life. Each deaf person is therefore intimately acquainted with nearly all the others of his own generation, while there are few opportunities for the formation of congenial and lasting intimacies with outsiders. The graduates of the institution organize themselves into societies or conventions for the promotion of social intercourse in adult life, and these societies are to be found in all large cities, in rooms where they meet for social intercourse, and for religious worship. They hold State and national conventions, which are attended by deaf-mutes of both sexes from all parts of the coun- try, and they publish newspapers and periodicals of their own which are filled with personal items. They are taught a special language which is as different from Eng- lish as French or German or Russian, and they learn to think in the gesture-language, so that English is apt to remain a foreign tongue, while they often write in broken English as a foreigner would speak, so that they are in a great measure cut off from all of our literature except its very simplest forms, and they have imperfect sources of in- formation upon topics which engage the interest of the rest of the community, such as social and political matters. Although there is no compulsion or infringement of personal lib- erty, all these influences combine to induce deaf-mutes to select for their partners in life persons who are familiar with the gesture-lan- guage, and with whom they have been thrown from childhood. We have, therefore, adopted most of the means which tend toward the formation of a deaf-mute variety of the human race, and time alone is necessary to accomplish the result ; but there are still other means which might be employed to hasten it. Professor Bell says that, with VOL. XXVII — 2 i8 THE POPULAR SCIENCE MONTHLY. this end in view, we might attempt to formulate some plan which should lead the deaf children of deaf-mutes to marry one another instead of marrying deaf-mutes who have not inherited their deafness, or to marry hearing persons belonging to families in which deafness is he- reditary. If, for instance, a number of the large deaf-mute families of the United States were to settle in a common place so as to form a community largely composed of deaf-mutes, then the deaf children born in the colony would be thrown into association with one another, and would probably marry in adult life or marry hearing persons belonging to deaf-mute families, and each succeeding generation of deaf-mutes would increase the probability of the deaf-mute element being rendered permanent by heredity ; and we might anticipate that a very few generations would suffice for the establishment of a perma- nent race of deaf-mutes with a language and literature of their own. Plans for the formation of such a community of deaf-mutes have many times been discussed by the deaf-mutes themselves, contribu- tions of money for the purpose have been publicly offered, and it has even been proposed to procure the enactment of laws to secure the descent of the land and other property in the deaf-mute line alone, so that the hearing children would be led to leave the community. A colony of this sort has even been founded in Manitoba, and twenty- four deaf-mutes with their families have already arrived from Europe and have settled upon the land, while more are expected this year. The analogy of all other organisms would lead us to expect that, with all these selective influences at work, the number of deaf-mutes should increase rapidly, and the interesting question, " How far do the facts justify this opinion ? " at once presents itself, and we ask, first, whether deafness is hereditary ; and, second, whether it is true that many deaf-mutes marry ; and, third, whether our system of education does lead those who marry to select deaf-mutes as their partners ; and, fourth, whether deafness is more frequent among their children than it is in the community at large. If the published records answer all these questions in the affirma- tive, it is clear that, however much the present system may appeal to our sympathies, it is neither the best one for the interests of the whole community, nor the best for the deaf themselves, since it tends to in- crease the evil which it is designed to alleviate. Few of the institutions publish any record regarding the relatives of pupils, but the records of the American Asylum, at Hartford, Con- necticut, show that, of 2,106 pupils admitted to that institution, 693, or nearly 33 per cent, were known to have deaf-mute relatives, and in the majority of these cases the pupils have more than one relative deaf and dumb, while in a few cases as many as 15 deaf-mute relatives are recorded. The report of this institution for 1877 shows that 593 pupils had one or more brothers or sisters deaf and dumb. 100 " " cousins " CAN MAN BE MODIFIED BY SELECTION? *9 47 pupils had one or more parents deaf and dumb. 38 29 48 u uncles or aunts deaf and dumb. a a a u a « children distant relatives grandparents 1 " " " great-grandparent 1 " " " great-uncle or aunt " That this is not peculiar to the pupils of this particular institution, and that it holds true of deaf-mutes in general, is shown by the fol- lowing table, compiled from the records of six institutions : INSTITUTIONS.

Percentage of pupils having deaf-mute relatives. 2,106 1,165 560 283 1,620 89 693 380 166 103 356 21 32-9 326 29*6 36-4 21-7 Texas Institution 23-6 Total 5,823 1,719 295 The table shows that, among 5,823 deaf-mutes taken from different parts of the country, 1,719, or 29^ per cent, are known to have had deaf-mute relatives, and that this is due to the influence of heredity is well shown when we contrast those who were born deaf with those who had afterward lost their hearing. Many of those who lose their hearing by accident or disease have no hereditary tendency to deaf- ness, but a considerable number of those who lose their hearing at some time after birth are born with an hereditary predisposition to deafness. If, therefore, we contrast the congenitally deaf with those who have become deaf, we should expect the latter class to have a much smaller percentage of deaf relatives than the former class, but a greater percentage than the community at large. Professor Bell has compiled the following two tables from the one which is given above, and they show that, while only about 13 per cent of the pupils which were not born deaf have deaf relatives, more than 54 per cent of the congenitally deaf pupils are recorded as hav- ing such relatives : Table II. — Proportion of the Non-eongenitally Deaf who have Deaf Relatives.

In answer to the second question, Do deaf-mutes marry ? Professor Bell gives a number of tables, one of which shows that, out of 1,259 pupils at the American Asylum and the Illinois Institution who were born before 1840, 571, or nearly balf (45"4 per cent), are recorded as married. The records for later years show a much smaller num- ber of marriages in proportion to the total number of pupils ; but this would necessarily be the case, because most of them are as yet children. In order to determine how many of this 45 per cent of deaf per- sons who marry chose deaf-mutes for their partners, Professor Bell has compiled the following table from the records of five of our largest institutions for the deaf and dumb : Table IV. — Proportion of the Deaf and Dumb who marry Deaf- Mutes. INSTITUTIONS. Total number of pupils recorded to have married. Total number recorded to have married deaf-mutes.

If it is true that our system of educating the deaf is responsible for the number of marriages between deaf persons, we should expect to find these marriages increasing in numbers, and Professor Bell has compiled from the table above quoted the following table, which shows that this is the case : YEAR OF BIRTH. Total recorded to have married. Total recorded to have married deaf-mutes. Percentage. Before 1810 129 715 233 12 72 577 196 11 55-8 1810 to 1839 80-7 1840 to 1859 84-1 917 These two tables show that the tendency of deaf-mutes to select deaf-mutes as their partners in marriage is very pronounced, and that it is much more developed now than it was during the early half of the century, and that it is steadily increasing. Thus there is every indication that this process of selection will go on from generation to generation, and that a large proportion of the deaf children of deaf parents will themselves marry, and that, of those who marry, the majority will marry deaf-mutes. If it is true that deafness is hereditary, this can have only one re- sult— the increase of deafness. There are very few reliable statistics regarding the number of chil- dren born to deaf-mutes, or the proportion of deaf children, but Dr. Turner, formerly the Principal of the American Asylum, stated, in 1868, that statistics carefully collated from records kept of deaf-mutes, as they have met in conventions at Hartford, show that in eighty-six families, with one parent a congenital deaf-mute, one tenth of the children were deaf; and in twenty-four families, with both parents congenital deaf- mutes, about one third were bom deaf. In 1854 Dr. Peet, the Principal of the New York Institution, said that, of all the families of which he had records, " about one in twenty have deaf-mute children ichere both parents are deaf-mutes, and about one in one hundred and thirty-five ichere only one is a deaf-mute ; and that the brother and sister of a deaf-mute are about as liable to have deaf-mute children as the deaf-mute himself, supposing each to marry into families that have, or each into families that have not, shown a predisposition toward deaf-dumbness" Our author has attempted to trace out from the scanty records the history of certain families in which deafness is hereditary, and he has expressed the facts in a number of graphic diagrams, two of which are here reproduced. 22 THE POPULAR SCIENCE MONTHLY. THE HOAGLAND FAMILY, OF KENTUCKY. In this family nineteen out of twenty-six descendants were deaf, and it is interesting to note that, although one of the members of the family was a hearing person, and married a hearing husband (Reed), their two children and three grandchildren were all deaf. One of the descendants, No. l,was •6 ts§» S «, « I I 2 IT'S ■oi^ o ii rO i; deaf and married a deaf - mute, but their five children all hear. No one could refer to this branch of the fam- ily as a proof that deaf- ness is not hereditary, however. The diagram on the following page shows the genealogy of the Fullerton family, of Hebron, New York : Fullerton had seven children, all deaf and dumb. There is no fur- ther information about six of these children or their descendants ; but the seventh, Jane Ful- lerton (1), married Sayles Works (2), who was also a deaf-mute, and all their six chil- dren were deaf and dumb. No information was obtained regard- ing the descendants of these six children. Those persons who are not familiar with logical reasoning will point to married deaf- mutes with hearing children as proof that such marriages are not to be condemned ; but, in order to prove that deafness is hereditary, it is not necessary to show that all the children of deaf parents are deaf, but only that the number of deaf children, g ^3 ill -o- ^- n c as- to £ .9 a J5 to a — © -O -O -o -o o o E a rt B to m to « o o c3 o rt ° u s •3 ^3 -3 CAN MAN BE MODIFIED BY SELECTION? 23 as compared with the hearing children, is greater than it is in the community as a whole, and this fact is proved beyond question by the statistics. The census returns show that there are 33,878 deaf-mutes in the country, or that one person out of every 1,500 is deaf ; or that, out of each 1,500 children who are born, 1,499 retain their hearing through- out life, while only one is deaf. If deaf children are no more numerous in the families of deaf parents than they are elsewhere in the community, only 23 out of the 33,878 deaf-mutes should have deaf parents ; but we have a record of nearly ten times this number, for Professor Bell states that, although Tullertcn. O 5 Wjrte. iNb inform aiiorv concerning the\ I descendant s. J m 6 6 jS 6 o {X~a\n{ormation> concerning the descendants.) THE FULLERTON FAMILY OP HEBRON, NEW YORL. only thirty-five of the fifty-eight institutions of the country have sent replies to his queries, the returns from these thirty-five show that no less than 207 deaf children of deaf parents have been admitted as pupils. Deaf children are, therefore, at least ten times as numerous in families where the parents are deaf as they are in the community at large, and it is impossible, after reading Professor Bell's paper, to doubt — 1. That deafness is hereditary ; 2. That, of the deaf persons who marry, nearly all select deaf partners ; 3. That their children are especially liable to deafness ; and, 4. That the number of deaf- mutes who marry deaf-mutes is increasing, and that our educational system fosters this tendency, and is to a great extent responsible for it. So far Professor Bell's conclusions seem to be unanswerable, and there is no room to doubt that the means that we have adopted for the amelioration of the conditions of the deaf have actually tended to^ increase the evil they were intended to diminish. 24- THE POPULAR SCIENCE MONTHLY. The question whether this can be avoided, while the system as a whole is retained, is one upon which there may well be a difference of opinion ; and the fact that the publication in 1868 of a paper on "He- reditary Deafness," by the Principal of the American Asylum, the Rev. W. W. Turner, has been followed by a decrease in the number of marriages between the pupils of that institution, seems to show that it may be possible to accomplish much by repressive influences. Our author believes, however, that the defect is inherent in our system, and that a complete change is necessary ; and that the segregation of deaf children in institutions, where they are kept by themselves, really lies at the root of the matter ; and that the grand central principle, which should guide us in our search for preventive measures, should be the retention of the normal environment during the period of edu- cation. The direction of change should therefore be toward the estab- lishment of small schools and the extension of the day-school plan. The average cost of the education of a deaf child in an American in- stitution is $223.28 per annum, and a small day-school could be main- tained at no greater cost, although the parents would be compelled to furnish, in addition, the industrial training which is now provided by the State ; but this would give no concern, for so many deaf-mutes are now earning their livelihood by trades which are not taught in the institutions as to demonstrate the practicability of apprenticing deaf-mutes in ordinary shops. The employment of the gesture-language and lack of articulate speech are efficient elements operating to separate deaf-mutes from hearing persons, and Professor Bell advises that all deaf pupils should receive instruction in articulation and in speech-reading. In the schools of Europe more than 65 per cent of the deaf and dumb were, in 1882, receiving efficient instruction in this way, and were taught to speak and understand the speech of hearing persons, while in our in- stitutions 4,241 pupils received no instruction whatever in articulation, and only 886, or 14 per cent, were under oral instruction. The question whether these remedies are the best and most prac- ticable ones or not may safely be left to the judgment of the able men who have devoted their lives to the subject ; but all those whose sympathies for this unfortunate class are strongly excited must bear in mind that the interests of the whole community are also to be con- sidered, and no one could, in the interest of humanity, or even in the interest of that small portion of the human race most directly con- cerned, advocate measures which lead to the perpetuation and increase of the evil. Whether we approve of Professor Bell's recommendations or not, all persons, those who hear as well as those who do not, must feel that he has done good service to the community by calling attention to the danger which now attends our system, but his paper is far more than a warning : it is a promise, and its direct practical bearing is a very CHOLERA. 25 small part of its value, for the facts which he has brought together prove that man can be modified by selection as readily as any of our domesticated animals or plants, and that increased knowledge will ultimately enable us to bring about rapid improvements in our race. CHOLEEA. By Dr. MAX VON PETTENKOFER.* IV. — PREVENTION. THE last sheet-anchor of the contagionists is always the linen of cholera-patients. But this view rests on such debatable ground that in the end it may prove to be fallacious. If cholera is really spread through human intercourse, then it is clear that the unknown specific something must accompany other vehicles, which may be man himself ; and if this something can cause illness in man, then it must reside in the system of the patient, and ought to be found there. There can be no doubt of this ; and I am prepared to admit as much. Thirty years ago I began my investigations on cholera in the belief that the germs of cholera were contained in the stools ; but afterward, having made sure that cholera was dependent on locality as well as human intercourse, I endeavored to see how this relationship obtained by ask- ing myself what was brought to the soil by man in his journeyings. The reply was, urine and stools — his excrements and nothing else. This view ripened into the belief that disinfection of the excreta and their receptacles ought to be a prophylactic measure against the spread of cholera, and excreta which had not been disinfected constituted a source of danger. These thoughts occupied me up to April, 18G6, when I published with my lamented friends, Griesinger and Wunder- lich, some regulations on cholera ; and I first relinquished these views when further study showed the uselessness of measures of disinfection as well as the harmlessness of the undisinfected excreta of cholera- patients. If the poison of cholera be contained in the excreta, then, individual predisposition aside, those who mostly come in contact with the excreta ought to be most frequently affected. And these should be the various physicians and nurses in hospitals devoted to the care of cholera-patients. But experience has clearly shown that the medical attendants in cases of cholera are not more prone to take the disease than others. The like holds good of nurses. Let us first of all consider how the facts stand in the home of cholera, in India. During 1867, in which the epidemic at Hurdwar prevailed, James Cuningham in- vestigated the relationship of cholera to nurses in forty garrison towns containing sixty-seven hospitals ; of the sixty-seven hospitals only eight * Reprint of a special translation made for the London " Lancet." 26 THE POPULAR SCIENCE MONTHLY. gave instances of cholera in the nurses ; the largest number of cases occurred at Dharmsala, where there were eleven, Kasanli had three, Muttra and Moradabad each two, Fazabacl, Lakknau, Mirat, and two others one each. An epidemic among the nurses can therefore only be spoken of in the hospital of the First Ghorka Regiment stationed at Dharmsala, where eight nurses, two porters, and one other officer were taken ill of the disease. These statements show how exceptional such occurrences are. Why should not a hospital as well as a garrison now and again be a center of infection ? Closer investigation proves, how- ever, that the personnel of the hospital at Dharmsala was not affected in a greater degree than the population outside the hospitals. It may be shown that the percentage of cases of cholera among the outside popula- tion was 8*01 ; in other words, that eighty-six cases occurred out of 1,073, while of the hospital staff of 127 eleven fell ill, or a percentage of 8*66. Cuningham also inquired whether the immunity enjoyed by nurses could be explained by disinfection. He found from ancient sources that this striking immunity of nurses was by no means a new thing, and had certainly obtained before the days of disinfection. He draws attention, among other writings, to an experience of Dr. Bruce, who wrote : " In 1848 cholera broke out among the infantry at Caenpur from May to September. During the whole time the hospital was never free from single cases of cholera, and at times it was overfilled with them. The whole institution may be said to have lived in the rooms of the sick ; the coolies did not leave the beds of the sick for an hour together, the physicians had much to do with the treatment of the patients ; and yet not a man, whether European, half-caste, or native, showed a single symptom of cholera. I took the greatest pains to col- lect and sift these circumstances, but in this year not a single instance occurred." In India a practical use is made of this knowledge under the exceptional circumstances of the nurses being attacked. Nothing is said of isolation and disinfection ; but the site on which the hospital stands is looked upon as unfavorable, and a change is made. This change of place is called by the English a movement, and as a pro- phylactic measure comes within the first ranks. If the site to which a movement has been made prove to be more unfavorable than that which was quitted — from the frying-pan into the fire — the movement has not availed anything. No good comes of the movement if the personnel has been already infected as much as possible. The Sixty- sixth Ghorka Regiment in its march through Tarai was not spared when it reached the Naini Valley ; but, probably, if it had stayed a day longer in Tarai, the percentage of illness, instead of being ten, would have been twenty. It is the same as regards nurses and hos- pitals in Europe. I shall refer to Munich intentionally, not because it had so frequently been the seat of cholera (Munich had cholera once to Berlin's twelve times), but because I am better acquainted with the particulars. During the epidemic of 1873-'74 we had three hospitals CHOLERA. 27 —the hospital on the left bank of the Isar, in Lindwurmstrasse, and that on the right bank of the river in Ismaningenstrasse, and the mili- tary hospital in Oberwiesenf eld. Cholera behaved in each hospital just as it behaved in the houses in their immediate neighborhood. Cases of cholera appeared in all three hospitals. In that on the left bank of the Isar there was rejoicing on account of the supposed success of isolation and disinfection until August loth, when the summer epidemic reached its height ; then an epidemic suddenly broke out. This was at the time that the epidemic developed in Lindwurmstrasse, in which the hospital was situate, and the epidemic in the hospital subsided as the epidemic in the street gave way. In the hospital on the right bank of the Isar the rejoicings lasted longer. The Ismaningenstrasse took no part in the summer epidemic, and neither did the residents of the hospital. But in the winter epidemic the same course of affairs took place as had occurred on the left bank of the river. The military hos- pital escaped all along. Of the seven barracks in Munich any cases or suspected cases of cholera were immediately sent to the military hos- pital. Now and again a surgical patient or a patient suffering from other illness than cholera was put among other patients, and later on suf- fered from cholera. Such cases were of course removed to the cholera division as soon as the stools betrayed the case. At times the cholera division was very full, and many nurses were employed therein ; but none of these fell ill or gave the least indication of cholera, though many of them must have come in very close relation with the cholera- stools. In the military hospital in Mullerstrasse the same facts were observed as were met with in the case of the other hospitals. Seeing how little contagious cholera is among the nurses, it appears very re- markable that the washers of cholera-linen should suffer so much. I think I hear a contagionist say that why nurses of cholera-patients in hospitals are not infected may be easily explained when it is borne in mind that great cleanliness exists, that there is much washing of hands, that they do not eat with unwashed hands, and that what- ever spurts on their clothes is rapidly dried, and dryness kills the bacillus. On the contrary, among the washers of cholera-linen it is easy to imagine that drops may be spurted into the mouth, or that in- fective material may be conveyed on wet fingers to the lips, and if a solitary bacillus gets into the intestines cholera may occur. How can this be seriously discussed ? Can it be supposed that the nurses wash their hands only in certain hospitals, and during certain times, and that the chances of taking in the bacilli are less during the cleansing and attention to a patient than in washing the clothes? Do such nurses never put the moistened fingers to their lips ? Do their noses never itch ? The explanation of the contagionists appears to me to be very comical. And yet there are cases in which the infection must have been derived from the linen soiled by cholera-stools. A very inter- esting case came under my observation at Lyons in the washing-village 28 THE POPULAR SCIENCE MONTHLY, of Craponne. In the " Gazette Medicale de Lyon " for 1854, page 252, we read from a letter by Dr. Gensoul : " In the month of July, 1854, two fugitives, a man and his wife, from cholera, alighted from Mar- seilles at the Milanese court. They had hardly arrived before they were attacked by cholera, the germs of which they had brought with them, and both died on July 17th. Some days later the washers of the Gasthof Bouchard in Craponne, a village about twelve kilometres from Lyons, came to fetch the linen for the wash. The soiled clothes and linen of the cases of cholera were given out in a separate bundle, placed in a separate part of the cart, and finally given to a washer- woman to clean. The washer-woman was struck down by a rapidly fatal cholera, and the washer's daughter shared the same fate. No other cases of cholera existed in the district on which the blame could be thrown. Such a choice of victims needs no comment." The cholera was not limited to the two cases. J. Garin (" Gazette Medi- cale," p. 309) says that eight cases of death followed in Craponne, and among them the washer's wife. From the statistics of Dr. Garin it is gathered that the disease attacked almost exclusively the washing- folk and their children. The population of Craponne numbers about 1,600 inhabitants, several families of which have charge of the wash- ing for the hotels of Lyons. As a later report of Dr. Bouchet showed, there were besides twenty-five other cases of cholera, with fifteen re- coveries and ten deaths, which occurred in the course of two months. The year 1854 was that in which the lower-lying parts of Lyons were invaded by an epidemic. It remains a striking fact that in the fair- sized village of Craponne cholera attacked almost exclusively the laundry -workers. With the exception of the washers, Craponne might be regarded as a place free from cholera. In 1855 severe epidemics prevailed in villages near Lyons — e. g., St. Bonnet and St. Laurent de Mure — though the outlying districts always enjoyed immunity from cholera. The same held good of other exempt districts. A very in- structive example of this kind is furnished by Stuttgart in 1854, wbich is usually exempt from cholera. At the time when the severe epi- demic prevailed at Munich an inhabitant of Stuttgart left Munich while he was suffering from diarrhoea, and arrived at Stuttgart, where he became worse and died of cholera. A few days later a case occurred in the person of a woman who had never left Stuttgart. She was the nurse of the case which had come from Munich. This case might be quoted as one of direct contagion. Again, after some days, a third case appeared, and this time it was the washer-woman who had cleaned the clothes of the first case. Finally, the washer-woman's husband suf- fered from cholerine. But no further cases appeared. Such cases are always wrongly interpreted by the contagionists as examples of direct infection, and such, at first sight, appears to be the case. If the case from Munich had infected the three at Stuttgart, how was it that none of the three infected other individuals ? For it must be remembered CHOLERA. 29 that the cases at Stuttgart and at Craponne must have been tended and their linen washed. How was it that no further cases occurred, and that an epidemic was not started ? The linen of the case from Munich was poisonous, but not that from the cases at Stuttgart ! Must we not also suppose that another factor is necessary to explain the fur- ther spread of cases introduced from without ? And this local factor was wanting at Craponne and Stuttgart. If a case from Munich caused three at Stuttgart, then the latter ought to produce nine. In places which enjoy immunity from epidemics it is conceivable that sporadic cases may occur, but, the conditions which are necessary for the production of an epidemic being wanting, no further development can take place. The soiled linen appears to me to be infective not be- cause it comes from cases of cholera, but on account of its arrival from a locality where cholera prevails. Perhaps linen is a good vehicle for transmitting the infective material produced in a locality under the necessary circumstances of time and place. Man is the only creature that wears linen, and perhaps he alone spreads cholera, and it is pos- sible that whether he were clothed or naked he would spread it just as much and no more. But, if we accept this doubtful solution of the Gordian knot, still the views of the contagionists on the dejecta of cholera and the soiled linen would not stand on a firmer basis, since we see not only individual cases but actual epidemics arising without the introduction of soiled linen. The infective material which produces cholera may be transmitted at all events in other ways along the paths of human intercourse. The germs of cholera may be brought from a locality to a place where the necessary relations of time and place are not favorable for the epidemic development of cholera, and they may there slumber for a month before they develop. There is every chance for the propagation of cholera in India, and yet cholera only shows itself fitfully in districts lying outside the endemic area. If the inter- course with India be reduced to the least possible, as it was in the last century, yet cholera might still at times visit us. Finally, I shall ask myself what can be done to ward off cholera ? The measures to be adopted will be very different according to the theory adopted. According to the contagionists, the spread of epi- demic cholera depends on personal and material intercourse, as well as on conditions of time and space when the germs arrive at certain localities. Moreover, the severity of the epidemic is supposed to de- pend on the individual susceptibility. If one of these three factors be wanting, an epidemic of cholera can not develop. Preventive meas- ures against cholera may be devised in one of three directions : (1) intercourse ; (2) disposition in time and place ; (3) individual predis- position. Measures to prevent the spread of cholera by interfering with human intercourse are, for many reasons, impracticable. If we ask ourselves what good has resulted from sanitary cordons, inspection, and quarantine, we are bound to answer, None. All these measures 3o THE POPULAR SCIENCE MONTHLY. have failed because they simply treat the individual, the possible case of cholera. But the germs of cholera may be transmitted in the ab- sence of the disease as manifested by illness. Even perfect sanitary cordons and quarantine would be also valueless, for the reason that they are commenced too late. It is true that quarantine and cordons may prevent a certain quantity of the germs of cholera from entering a country, so that it will serve as much purpose as a good custom-house against smuggling. But there is a great difference between articles of commerce and germs of cholera. The germs of disease are capable of multiplication, and so the smuggling through of a few may, under suitable circumstances, be the means for the development of millions and billions. The epidemics at Toulon and Marseilles afford excellent illustrations of my argument. Paris has not yet been attacked, while all the regulations have failed to prevent the appearance of cholera at Naples. No doubt inspection of ships is a good regulation as tending to discover unhygienic conditions, but it is useless as preventing the transmission of cholera. Inspection of places where cholera prevails, the disinfection of articles coming from localities where cholera is, as well also as the places where the dead are laid, are important matters, but too much is not to be expected from these measures. The preva- lence of contagious diseases like small-pox can not be much dimin- ished by attempts to limit intercommunication. Protection from small-pox by vaccination, which leaves human intercourse free, has been followed by success. But we have not at our command a simple and sovereign remedy by means of which the individual predisposition to cholera may be done away with, and yet we can do something in this direction. Everything which tends to lower the general health and cause depression, but especially those conditions which induce diar- rhoea, predisposes to cholera. To these matters every one must look for himself, and his own efforts may be aided by the advice of doctors. The organs of public health may also effect much. Medical treatment should be obtained for the earliest cases of cholera and of diarrhoea. Care must be taken by the authorities and by the community to take measures for the treatment of the sick. But the difficult point in the prevention of cholera is the predisposition in time and place. It is no use urging, as the contagionists do, that we can not change the nature of the soil. One of the established facts concerning epidemics of cholera is the tendency of the disease to rage in those quarters where the greatest filth prevails. All towns which have been provided with good drainage and water-supply have lost their susceptibility to cholera. England affords the best example of this fact. In 1849 there were recorded 53,237 deaths from cholera, in 1854 the numbers were 20,097, and in 1866 only 14,378, while from 1872 to 1874, when several epi- demics prevailed on the Continent, cholera did not reach England. I do not imagine that this immunity was due to the want of predisposi- tion to cholera as regards conditions of time. The case of Fort Will- METHODS OF TEACHING POLITICAL ECONOMY. 31 iam in Calcutta may be again referred to, as there, I believe, the immunity from cholera now enjoyed was due not merely to the intro- duction of a better supply of water, but largely also to the improve- ment in the other matters of hygiene. -++*- METHODS OF TEACHING POLITICAL ECONOMY. Br J. LAUEENCE LAUGHLIN, Ph. D., ASSISTANT PEOFESSOE OF POLITICAL ECONOMY IN IIAEVAED UNIVEESITT. A NATION is sometimes so bitterly taught by sad experience in financial errors — as was the case with France in John Law's time, and again in the issue of paper assignats during the Revolution — that, on the principle of the "burned child," it ever afterward finds that it unconsciously keeps to the right and avoids the wrong path. So that to-day France is a country where correct conceptions of money are almost universal, and her public monetary experiments are, as a rule, most admirably conducted. In somewhat the same way does the individual gain his proper knowledge of political economy. Principles must be seen working in a concrete form. The key to efficient teach- ing of the subject is to connect principles with actual facts ; and this process must go on in the beginner's mind only through experience. By experience, I mean the personal (subjective) effort of each one to realize the working of the principle for himself in the facts of his own knowledge. The pupil must be put in the way of assimilating for himself the principles of his subject, in such a manner that he feels their truth because they are apparent in explanation of concrete things all around him. And for this purpose nothing is so useful as a sharp struggle, an effort, a keen discussion, or possibly a failure of compre- hension at the time ; for nothing will so awaken one to intellectual effort and finally result in the safe lodgment of the principle within one's thinking as an obstruction and its removal. That this is the aim to be always kept in view by the teacher and student is made clear, it is to be hoped, by the previous analysis of the " Character and Dis- cipline of Political Economy." It is now my purpose to make some suggestions as to the practical methods of teaching by which this can be carried into effect : 1. The relative advantages of lectures and recitations in political economy have never, to my knowledge, been openly discussed. An experience with both methods of teaching leads me to think that the lecture system, pure and simple, is so ineffective that it ought to be set aside at once as entirely undesirable. No matter how clear the exposi- tion of the principles maybe, no matter how fresh and striking the illus- trations, it still remains that the student is relieved by the instructor 32 THE POPULAR SCIENCE MONTHLY. from carrying on the mental processes which he ought to go through for himself. In fact, the clearer the exposition by the lecturer, the less is left to the student — the lecturer, in fact, is the chief gainer by the system. Moreover, while listening to a connected and logical un- folding of the principles, the student is lulled into a false belief that, as he understands all that has been so clearly presented to him, he knows the subject quite well enough ; and the result is to send out a number of conceited men who really can not carry on a rational eco- nomic discussion. They wholly miss the discipline which gives ex- actitude, mental breadth, keenness, and power to express themselves plainly and to the point. Then, not being forced to think over a principle in its application to various phases of concrete phenomena, they know the principle only in connection with the illustrations given by the lecturer, while they utterly fail to assimilate the principles into their own thinking. The subject then becomes to them a matter of memory. They memorize the general statements without ever real- izing their practical side, and that which is memorized for the day of examination is forgotten more speedily than it is learned, and the sum total of the discipline has been simply a stretching of the memory. In fact, with the average student in almost any subject the lecture system leads to cramming, At the best, it affords a constant temptation to put off that kind of internal struggle which must be gone through with — a period of doubts and questions — by which alone a clearer con- ception of the subject ultimately emerges. In fact, it is doubtful if the student ever gets much, if any, of that mental attrition on the sub- ject which is the most valuable part of the work. An experience of a year in lecturing to a class of two hundred and fifty, including the best and the poorest men in the university, convinced me of the truth of the above position ; and their examination-books were the most un- satisfactory I had read for years. The usual alternative to the lecture system is the plan of recitations from a text-book. Even the simplest form of recitations is, in my opinion, better than listening to lectures. At least, the student is put to it to express the sense in words under the criticism of the teacher. But this plan has its evident difficulties. If the pupil is called upon for only what is contained in the book, he falls into the habit of mem- orizing, and fails to think for himself. If you give him the clew, he can tell you on what part of the page the statement is found, and can put the idea in the language of the book ; but he knows nothing of the power of applying it to what he sees. If the learner is very clever and inquisitive, he may do something for himself, but the average pupil quite misses the real good of such a course. 2. As it is evident that neither lectures nor formal recitations in the old fashion are satisfactory, we are inevitably led to adopt a plan which possesses the advantages of both. Some text-book is essential as a basis for the instruction. In it the pupil should find an exposition METHODS OF TEACHING POLITICAL ECONOMY. 33 of the principles and a provocation to apply them to practical things as he reads. Then he comes to the class-room as intelligently familiar with the principles as his reading can make him. Now comes the work of the instructor. At first it is surprising how easy it is to show even to the best men a gap in their knowledge, or a misunder- standing of the principle. Present an illustration different from that of the book, and ask them to explain the situation. The necessity of seeing the essential point in the facts, and the attempt to describe the operation of the principle, will effectually rout the man who has merely memorized the book, and teach him to think out the matter more thor- oughly for himself in the future. The teacher, also, will try to find out the accidental obstacles which in a young mind obstruct the un- derstanding of the point in question. Let the pupil be asked to state the matter, and let the teacher note the imperfections. Now he can stimulate another student by questioning him as to one of these imper- fections. If a clear correction is not obtained from a member of the class, let the instructor apply the Socratic method. At first ask a question which the learner readily understands, and then lead him naturally and gradually by logical steps up to the point wherein he had failed of understanding. He will then see his own difficulty, and at the same time he has had a little robust exercise for his mind. If this is carried on before his fellows, it will the better cultivate cool- ness and self-control before an audience. 3. Above all, the hour should not be wasted in simply rehearsing what has been read in the book. The student should go away from the class-room feeling that he has received some new idea, or some interesting fact which illustrates his subject. The work of the class- room should be cumulative in its effect as compared with the fruits of text-book reading. The teacher should in every way stimulate ques- tions from members of his class, and urge the statement by them, either orally or in writing, of their doubts and difficulties. If there is some timidity in presenting a weakness in the presence of a class, ask some more manly person of the number, and the timid student will soon see that others are not much better off than he. In fact, all will have difficulties in understanding, or in interpreting principles, some trivial, some serious ; and the pupil will become discouraged unless these are removed. When each one sees that others are also hindered by obstacles, there will be a greater freedom in asking questions. Moreover, in order to keep up a steady and regular training, which will produce the best disciplinary results, let the questions of the in- structor every day run backward in review, and especially aim to bring out the connection of one part of the subject with another. It will be very effective if done just about the time that the past work is growing a little dim before the presence of newer ideas. In no sub- ject, perhaps, more than in political economy, is it necessary to know the preliminary stages in order to understand the later work ; so that VOL. XXVII. — 3 34 THE POPULAR SCIENCE MONTHLY. the pupil must be actually in possession of principles previously ex- pounded for which he may be called upon at any time. It is simply impossible for a person to be absent and neglectful for a time in his study, and then come into the class-room to make a brilliant show on an intermediate fragment of the subject. He can be too easily exposed as a humbug to attempt it a second time. Moreover, thus to force him to do the work as he goes along is the greatest favor one can do for the pupil ; and the usual cramming before the examination becomes, in reality, a general review, which is very useful in bringing him to see the connection existing throughout the whole subject. 4. If the class is too large to reach each member as often as the instructor might wish in the above method, there is one device which is more or less useful. At the beginning of the hour let him write a question upon the blackboard, to be answered by each one in writing within the first fifteen minutes. The attempt to write out an explana- tion clearly, without hint or clew from the instructor, will reveal to the best student the deficiencies and gaps in his knowledge. Each one will then have the keenest interest to know what is considered a satis- factory answer to the question. At the next exercise of the class, the instructor can read some good and some bad answers, point out the general mistakes, and advise them for the future. No exercise can be better than this in cultivating the habit of careful expression, and in learning how to make a clear and pointed exposition of a subject in a brief space of time. This practice tends to secure the accuracy which in the oral discussions is made second to fluency and readiness. 5. Since the chief work of the class-room is not to enable students to discover principles, but rather to understand and apply them, prob- ably the most useful method of interesting a class is to present to them by extracts from the newspapers of the day bits of fallacious dis. cussions which may come under the head of the subject in hand, and ask for criticism and discussion of them. The appositeness of a timely topic is peculiarly valuable for such purposes. In fact, the practical matters of our own country will never fail to excite a lively interest in almost any class ; and through this interest the teacher can find a way of leading men to study principles more carefully. A national or State campaign is very likely to furnish an instructor with a plenti- ful supply of extracts for discussion by his class. The learner in po- litical economy is not hindered by the same disagreeable obstacles, as impede the medical student, in finding subjects on which to put his learning into practice. 6. Many minds are unable to keep hold of an abstraction, or gen- eral principle ; or they have been untrained in making nice distinc- tions between ideas or definitions. Just as in beginning a strange lan- guage, when words of widely different meaning have a similarity to the untutored eye, the distinctions do not make much impression. So it is in regard to ideas and definitions in political economy. There- METHODS OF TEACHING POLITICAL ECONOMY. 35 fore, visible expression of the abstract relationships, by diagrams, or by any figures which represent the abstract in a concrete form, will be of very considerable service to the ordinary student. This matter seems to me to be of such practical importance in teaching that it will be worth while to illustrate my meaning by a few examples : (a.) Since material wealth comprises all things that have value ; since capital is only that wealth employed in reproduc- tion, and not used by the owner himself ; and since money is that part of wealth in circulation aiding in the transfer of goods — the relations be- tween the three may be expressed to the com- monest apprehension by some such device as the following, in which the area of circle A represents the amount of wealth ; B, the capital saved out of the total wealth ; and C, the money by which goods are transferred — only that part of circle C being capital which, inside of circle B, is being used as a means to production. Again (6), it is seen that different classes of laborers, arranged ac- cording to their skill, form, as it were, social strata, of which the largest and the poorest paid is composed of the unskilled laborers at the bottom. This may be shown to the eye at once by the sections of a pyramid, in which A represents the largest and least paid class ; B, C, and D, etc., the better-educated, and relatively more skillful laborers ; ending finally in the few, at the top, of the most competent executive man- agers. Now, if A were to become as fully skilled as B, and competi- tion should become free between all members of A and B ; and if this were to go on in the same way to include C— the effects of this break- ing down of the barriers which hinder competition might be illus- trated by the following changes in the above pyramid : the areas of A, B, and C may be thrown together into one area within the whole of which movement and choice is perfectly free to the laborer, and wherein wages are in proportion to sacrifice. This can be done by striking out the lines of division between A, B, and C, and by rep- resenting the change by the area included between the base and the dotted lines. Examples might be continued in illustration of my method, but these must suffice. By this means there can be planted inside even the 3 6 THE POPULAR SCIENCE MONTHLY. dull mind an outline of an idea which can then be modeled and shaded to the condition of a natural truth. The teacher will find, by experience, that an idea thus given is very seldom forgotten. The pupil has thus once turned the abstraction into a concrete form, and he can now use it for himself after he has once grasped it. It does not at all imply that he will get hard and definite conceptions of hu- man affairs by this process ; for he is shown that the principle which he has once seen in a concrete form, appears in other forms, and he is constantly seeing that it is so. 7. In close connection with this method, but having an entirely different purpose in view, is the use of charts and graphic representa- tions of statistics. The method just described above aimed to help in finding concrete expressions for the general principles ; but graphic methods usually have as their object to assist in that part of the eco- nomic process heretofore referred to as verification. Every one knows the common dislike of dreary statistics ; to many persons columns of statistics are repellent or meaningless. Collections of facts regarding banking, finance, taxation, and wages become a tangle in which one's direction is constantly lost. But arranged graphically the whole di- rection of a movement is seen at once, and the mind takes in new and unexpected changes, which force an investigation into their cause. Moreover, there comes a certain breadth of treatment, when, in look- ing at the facts graphically expressed, one is able to see the whole field at once. There is no waste of thought on temporary and acci- dental movements, for the action is seen from beginning to end at one glance. There are many charts which would illustrate this meaning very distinctly ; but perhaps none are simpler than the one here appended, showing the steady and continuous fall in the value of sil- ver relatively to gold since the discovery of the New World. No one has ever claimed that there has been any " unfriendliness " displayed toward silver in the legislation of the chief countries of the world be- fore 1816, at the farthest, and yet the white metal had been steadily on the decline ever since the Spanish galleons, in the fifteenth century, began to pour the precious metals of America into the coffers of Spain. In short, the more extended collection of economic data is now rendered possible by the better methods employed in census and sta- tistical bureaus, and the resort to the work of verification of economic principles by the examination of these data is the one thing only which can redeem political economy from the baseless and common charge of being a set of impractical formulae. Into this work one can carry no instrument so effective and helpful as graphic represen- tations. In fact, the investigator, after having collected his tables and columns of figures, will find his gain in first putting them in some graphic form, before he can intelligently see exactly with what he has to grapple ; then he can turn his energies directly upon the prob- lems disclosed by the chart to every other eye as well as his own.

Some printers can now rule this paper in squares to suit the convenience of the worker ; but these guiding-lines ought to be faint, and not so heavy as to over- power the lines of the chart. So far I have been speaking of charts for the class-room. Perhaps, in their own good time, such economic charts can be bought of educational agencies. But ordinary co-ordi- nate paper, on a small scale, is the best form in which to first arrange the chart. It can be purchased in sheets at a small price, and is invalu- able for both student and instructor. In fact, no lesson is more stimu- lating to a class than to give them the data of a subject and ask them to put it into graphic form. For the first time they begin to realize that statistics are not dry ; indeed, any one who has turned over the pages of Walker's " Statistical Atlas " will find out for himself how the columns of census tables can talk to him in forms and colors with- out producing weariness, but even with a power to give a sense of sur- prise at the interest they excite. 8. When the instructor comes to examinations he will find several difficulties. In making out questions he ought to keep in view that they should be arranged so as to test not the memory, but the power of the pupil to apply principles. For this reason the ideal paper should contain nothing which the student has seen in that form before. The facts he is called upon to explain ought to be fresh ones, and the falla- cies he is to examine should be such as he had not previously consid- ered. But for practical purposes it seems best to remember that a class is composed of all kinds of persons, and, while the majority of the questions should be of the character which I have described, yet at least a few easier and more encouraging questions should be set. The student should be instructed to study each question with care ; and avoid haste in answering, before he is sure that he has really caught the point and essential idea of the question. Fairly good stu- dents often write about the question, but do not answer it. It should be definitely understood that no credit is given for such answers. Then, also, the examination can be used as a teaching process ; since, by inserting an important subject, the attention given to it at these times will be such as to keep it from speedy oblivion. Moreover, it will be well, after the examination, to read a good and a poor answer to each question before the class. They will know better what is ex- pected of them in the future — like troops after their first fight. After- such an examination the instructor will find his class much more dis- ciplined and more ready to exert themselves in the intellectual wrest- ling. The vigorous preparation for the examination has really given them a better grasp of the subject, and the teacher can easily bring on a warm discussion now, because they really know something and feel that they know it. 9. When first approaching the study, it has been found to be of service to some students to suggest that on the first reading of the METHODS OF TEACHING POLITICAL ECONOMY. 39 text-book they note in the margins in a few penciled words the gist of each paragraph as it is read ; then, at the close of the chapter, to advise the reader to review it by means of his marginal notes, and then make a general but brief synopsis of the chapter. This will both save time and teach that essential thing — how to study rapidly but thoroughly. It will destroy aimless reading, which is so common in these days of many books. 10. In advanced courses, much of what has been said in regard to these details will be less important, for the teaching is necessarily dif- ferent in kind. Such courses naturally fall either (1) into those which continue to study principles, as the systems of various writers or schools of political economy in the past and present, or (2) into those which treat historical or practical questions. In the former the lecture system is unsatisfactory for reasons given above ; and the class should themselves be constantly wrestling with the fuller discussion of sub- jects in which they can hitherto have had only a general knowledge. Experience seems to show that a topic, furnished with references to writers, affords the best method of procedure. This, of course, implies a good working library and a list of reserved books. In the practical courses a large part of the training consists in teach- ing the student how to use books, how to familiarize himself with the principal storehouses of statistics, such, for example, as the English " Parliamentary Documents," or our own Government publications ; how to collect his materials in a useful form ; and then how to apply graphic representation wherever possible. The greatest good comes, of course, from putting the student on his own resources at once and forcing him to find his own materials, look up his own books and authorities, and come to a conclusion on the subject assigned to him independently of all aid or suggestion. The instructor can then at the conferences take up a paper for criticism and discussion, or first assign it to another member for that purpose. This is a feasible plan ; but, if carried on throughout a whole course, it requires of the student so much time that his other work must suffer, and, in addition, but few subjects can be taken up in this thorough and leisurely way. In prac- tice it has been found best to use the lecture system partially. One subject can be taken up by the instructor at regular exercises, for which he furnishes beforehand the references, and partly lectures and partly discusses the subject with his class, thus guiding them steadily over the field and directing the disposition of the time to be devoted to each subject. In this way many more subjects can be reached during the year. But the advantages of the investigating method can be partly retained by requiring a monograph from each member of the class on a practical subject of his own selection from a list prepared by the instructor, and this thesis can count for attendance on part of the lecture-work. In this thesis the student is pushed to do his best to give a really serious study to some particular topic, and he 4o THE POPULAR SCIENCE MONTHLY. is expected to do it independently of any aid beyond general oversight and direction ; and he is warned that the paper will be of greater value, provided it contain the bibliography of the subject and con- stant reference by page and volume to his authorities. 11. The preparation of bibliographies is part of a teacher's duty. Moreover, he who has access to a rich and well-appointed library can do a service to the rest of his guild by leaving behind him notes of his bookish experiences. He can in a few words say whether a book is good or bad for a particular purpose, or indicate what part of it contains a valuable discussion, or furnishes useful facts in a subject within the study. For this purpose it has been a great convenience to have little blank-books of ordinary stiff manila paper, six inches by three, with each page perforated like postage-stamps near the butt of the book, so that each page can be torn off smoothly. On this page a book can be entered under a suitable heading, with its exact title and author, and room still be left for a very generous amount of criti- cism or commendation, or for noting the contents of the book. The cards can be laid away alphabetically by subjects in a drawer, and will prove of invaluable aid at many times. Books of which one has heard but never seen, can also be entered with a star, to be erased when a book has been examined. This systematic habit is peculiarly desirable when one is hunting for the facts on a certain subject. One will in this way lose nothing by forgetting where a statement has once been seen. In this brief and inadequate way I have attempted to suggest from my own experience what may enable others to avoid difficulties, and possibly to aid in a more rational method of teaching political econ- omy. It is scarcely more probable that what I have said is all new than that others should agree with me throughout in what I have ad- vanced ; nor is it unlikely that other teachers may have many other suggestions to make in addition to mine. If my efforts may call them out and aid in better methods of teaching, I shall be amply repaid. LOST COLONIES OF NORTHMEN AND PORTUGUESE * By E. G. HALIBUKTON. "ATO one can find a "message from the sea," telling of the fate of -L-^l some long-missing vessel, without a feeling of emotion ; but the stray waifs that throw light on the history of lost colonies are of a deeper interest, for they supply missing chapters in the annals of colonization and early maritime enterprise. * Abridged from a paper read before the Geographical Section of the British Associa- tion at Montreal. LOST COLONIES OF NORTHMEN AND PORTUGUESE. 41 The probable dates of those that are the subject of this paper are : 1. Vinland the Good, discovered a. d. 994 ; 2. Fagundes's settlement in Cape Breton, a. d. 1521 ; 3. A second Portuguese settlement in Cape Breton, a. d. 1567 ; 4. A Spanish settlement in Cape Breton, between 1580 and 1597. I. Vinland the Good. — It is unfortunate that the early settlers ever thought of calling a place near Rhode Island Martha's Vine- yard, for its resemblance to Vinland has led Danish and American archaeologists to identify them as the same locality. They seem not to have remembered, that wild grapes are found on the south shore of the gulf and river St. Lawrence, from Cape North to Quebec, the Island of Orleans having for this reason been called the Island of Bacchus. Wild grapes, too, are found on the west coast of New- foundland, according to Anspach ; and in 1521 the Portuguese colo- nists in Cape Breton sent word home that among the products of that country were grapes. The writer of this paper has tasted some excellent wine made by a relative living at Fredericton, New Bruns- wick, from the wild grapes that are to be seen hanging in clusters from the elm-trees on the intervale lands along the St. John River. But as Vinland and Martha's Vineyard were assumed to be the same, a voyage by the Northmen from Greenland, not exceeding seven or eight days, has been extended to Rhode Island, and the circumnavi- gation of Newfoundland and Nova Scotia has been assumed, although the Saga of Eric the Red is silent as to it, and though such a voyage, still a perilous one, was at that time a most difficult and dangerous undertaking. The Saga of Eric the Red was written in Greenland by, or in honor of, Eric and his family, Avho were the discoverers, explorers, and chroniclers of Vinland the Good. The later Saga of his son-in-law, Karlsefne, which, like the geo- graphical notices quoted by Rafn, was written in Iceland, was evi- dently based, not on information derived from people who had been in Vinland, but on an imperfect version of the Greenland Saga, for al- most all the courses described by them differ 90° from those given in the Saga of Eric the Red, a uniformity of error which must have arisen from the use of a sketch-map of the voyage to Vinland, in which the points of the compass were omitted or incorrectly placed. What is north in the one is generally east in the other. We have therefore to depend on the Greenland Saga, and what are its claims to be considered a credible authority ? It was written in glorification of Eric and his family, and describes the discoveries made by his sons or sons-in-law, and testified to by no one outside of his family circle. Two persons, father and son, the latter of whom was named Eric the Red, having been guilty of murder in Norway, took refuge in Ice- land, where Eric committed one if not two more murders, and in con- 42 THE POPULAR SCIENCE MONTHLY. sequence of them, and of his constant broils and feuds with his neigh- bors, was banished and outlawed. As the world Avas too small for him, he was tempted to try to discover and explore the new land in the West, of the existence of which there were rumors. He therefore sailed west, and discovered an ice-bound country, which he called " Greenland," because, quoth he, " people will be attracted to it if the land has a good name." This intended fraud upon emigrants was an example that was fol- lowed in his own day, as well as in later times, for an imaginative chronicler subsequently asserted that " there is the best of wheat in Greenland." In a. d. 994 Eric and his son Leif, having heard of new lands far- ther west having been sighted by Bjarne, made up their minds to ex- plore them, and for that purpose bought and fitted out Bjarne's ves- sel. But Eric while on his way to the port was thrown by his horse, and took his fall as an omen that he was not destined to give any more Greenlands to the world, and he therefore allowed Leif to sail without him., But, from what we know of his proclivities, we may be quite sure that he had a wonderful name already coined for that neAV land — Vinland the Good. Could words picture a more attractive bait for emigrants '? How much of the story of the subsequent exploration of Vinland by his son Leif is purely imaginary it is difficult to say. All that re- lates to ship-loads of grapes, self-sown fields of wheat, and the genial semi-tropical winter climate of that favored land, we may dismiss as myths or exaggerations. Where, then, was Vinland situated ? We have one test, viz., the length of the shortest day there. Pro- fessor Thorfaeus, who wrote at the beginning of the last century, found that it indicated 49° north, i. e., the latitude of Newfoundland, Avhich was probably very near the mark, for, though Rafn contends for the latitude of Rhode Island, 41° 24' 10" north, the latest authority, the Icelandic-English Dictionary by Gudbrand Vigfasson (Oxford, 1874), makes the hours of sunrise and sunset 8.30 a. m. and 3.30 p. m. (instead of 7.30 a. m. and 4.30 p. m., as Rafn contends), and therefore carries back Vinland to Greenland. There is no part of the coast from Greenland to Rhode Island which has not been pounced upon by some writer as the site of Vin- land. We can not depend on the sailing directions of the Sagas, and Cap- tain Graah has shown that, preserved for a long time only by oral traditions, they have been changed to suit the fancy of the different persons to whom we are indebted for their preservation. We have, however, besides the length of the shortest day, another guide, viz., that the natives met at Vinland were Eskimos, or a race resembling them in their boats, etc. — such as the Naskapi, or " Mountaineers," who are found occasionally in Newfoundland. The advocates of the Rhode LOST COLONIES OF NORTHMEN AND PORTUGUESE. 43 Island theory, in order to explain the presence of Eskimos so far south, have started the hypothesis that the Skraellings at the beginning of the eleventh century inhabited the eastern coast of North America as far south as Rhode Island, but were driven into the Arctic regions by the races now found on the sea-coast. Not a particle of evidence can be ad- duced to support this idea, and the authorities cited by Rafn disprove it, for an Icelandic geographer describes the more northern country, Furderstrands, as too cold for human habitations, and as bounded on the south by Skraellingsland. Their home, therefore, was then, as it still is, Labrador. Fi'om the various accounts given by Rafn, I prepared a map, show- 44 THE POPULAR SCIENCE MONTHLY. ing Helluland, Markland, and Vinland, which proved to agree almost with the maps of the Northern Atlantic by the Icelander Sigurd Stepha- nius (1570), and by Gudbrandius Torlacius (1606), except that I made Genunga Gap run between Markland and Vinland, in accordance with one of the authorities quoted by him. It is clear that what is now called Greenland was assumed to be an extension of the north of Europe, and that " Greenland " embraced all the country north of the Strait of Belleisle. Davis Strait was looked upon as an inlet running into Greenland, but not as a strait sepai'ating Greenland from the land to the westward. The land north of Hudson Strait was called Furderstrands, and was so cold as not to be habitable. All the country south of Hudson Strait was called Helluland, as well as Skraellingsland (our Labrador), and it was divided into Great Hellu- land to the north, and Little Helluland or Markland to the south. In one account, however, Little Helluland is omitted and Labrador divided into Helluland and Markland, the latter being to the south. The Westbygda of Greenland, so often referred to, was on the east side of Davis Strait, and was the site of the cathedral. Assuming such to be the case, the accounts quoted by Rafn will at once become intelligible and consistent, though totally at variance with his theory, which identifies Great Helluland with Labrador, Little Helluland with New- foundland, and Markland with Nova Scotia. Rafn quotes the following notice of Vinland from a fragment of the "Vellum Codex," No. 192, supposed to have been written about the end of the fourteenth century : " From Bjarmeland [in Europe] extends uninhabited land toward the north, until Greenland begins ; south of Greenland is Helluland ; next lies Markland ; thence it is not far to Vinland the Good, which some think goes out of Africa ; and if so, the sea must run between Vinland and Markland." This, I contend, points to Newfoundland, which extends toward Africa, and is separated from Markland (Labrador) by the Strait of Belleisle. He adds, "All these countries are in that part of the world called Europe," an idea that prevailed even after the discovery of America by Columbus. With this account agrees one of a very early date : * " Now is to be told what lies opposite Greenland, out from the bay which has been before named. The land is called Furderstrands. There are so strong frosts there that it is not habitable, so far as one knows. South from that is Helluland, which is called Skraellingsland ; from thence it is not far to Vinland the Good, which some think goes out from Africa." Hence it is clear that the Northmen placed the land of the Eskimos between a northerly uninhabitable region and the more southern Vin- land. The same description says, "Between Vinland and Greenland is Genunga Gap, which flows from the sea called Mare Oceanum, and * " Gripla. Antiq. Am.," p. 2S0. LOST COLONIES OF NORTHMEN AND PORTUGUESE. 45 surrounds the whole earth." This is the " River Ocean " of Homer, and is used in the Eddas as the name of the watery wastes of Chaos. Bjarne's voyage to Vinland seems to have really taken place, and to have been accurately described. The accounts of subsequent voy- ages appear to have been based on Bjarne's, and to be as nearly as possible mere transcripts of it reversed. In 906 Bjarne sailed from Iceland to Greenland, but "after three days' sailing, . . . the land was out of sight under the water," he was driven southward by north winds, with foggy weather for many days. At length he once more saw the sun, and having sailed one day more he sighted land. As the wind had changed from north to southwest, in which quarter it remained steady, it is evident that the northerly gale went round with the sun, i. e., to the east, then to the south, and then to south- west. Had the wind " backed " to the west and southwest, the weather would have been continued unsettled. Hence we conclude that Bjarne's vessel was driven to the banks of Newfoundland, where fogs constantly prevail, whence, the wind veering to the east, south, and southwest, he was driven into the Gulf of St. Lawrence and around Newfoundland. The land he first saw was " without mountains, and covered with wood, and had small heights." It was on his larboard side, and was probably one of the Magdalen Islands, or possibly the eastern end of Prince Edward Island. Afterward they sailed two days, when they saw " a flat land covered with wood." This may have been the northwest coast of Newfoundland near the west end of the Strait of Belleisle, which for a long distance is marked on Bayfield's chart as a "low limestone coast." I am informed that there are woods on it, though they may be small compared with the vast forests that are found up the rivers, whence extensive lumbering operations are now being car- ried on. Bjarne then put to sea for three days, with a southwesterly wind, and saw a third land, which was " high and covered with mount- ains and ice-hills." They coasted along it, and "saw it was an island." They probably sighted Labrador, and, rounding its southeast point, supposed it to be an island. Thence they sailed with the same favor- able southwesterly wind (which grew into a gale) for four days, when they sighted a " fourth land, which was Greenland." Leif's voyage to Vinland seems, as nearly as possible, a version of Bjarne's reversed. Neither time nor bearings are given, and we are merely told that Leif " found the land first which Bjarne had found last." * They saw no grass there. " Great icebergs were over all up the country, but like a plain of flat stones was all from the sea to the mountains." This they called Helluland. They then sailed thence and found another land which was " flat and covered with wood, and white sands were far around where they went, and the * In the account of the Saga of Eric the Red, of Karlsefne's voyage, it is simply stated that he sailed to Vinland. The Icelandic Saga of a later date was less cautious, and gives many impossible courses. 46 THE POPULAR SCIENCE MONTHLY. shore was low." This was therefore called " Markland," i. e., wood- land. They sailed thence for two days with a northeasterly wind (the opposite to that which Bjarne met with), when they sighted an island to the northward of the land, and sailed into a sound between it and a cape which ran out northwardly from the land. Thence they sailed westwardly round the cape into a place where at ebb-tide the vessel was left high and dry some distance from the shore ; and when the tide rose they towed the vessel into a river, which led into a lake (or inlet ?), where they landed and built booths. If this narrative is something more than a Norse " Odyssey " or a fiction, we must infer that Leif touched at Labrador (called by him Helluland), sailed thence to some more southern part of Labrador (called by him Markland), and thence past the Island of Belleisle into one of the many shallow inlets on the south side of the Strait of Belle- isle. The " low land covered with wTood " and its " white sands " may possibly be the part of Newfoundland sighted by Bjarne, or it may be Blanc Sablon, near Bradore Bay, on the south coast of Labrador. It is, however, evident that Leif can not have reached the south coast of the Gulf of St. Lawrence, judging by the number of days expended on the voyage. The Saga of Karlsefne says that the voyage from Greenland to Helluland only took two days, and that from Helluland to Markland three days. Now, Leif's voyage from Markland to Vin- land took two days, or the number of days spent by Bjarne in going from the land first sighted by him to the "flat land covered with wood." Bjarne's voyage from the first land sighted by him to Green- land occupied in all 2 -f- 3 + 4 = 9 days. From the Sagas of Eric the Red and of Karlsefne, we learn that the voyages from Greenland to Vinland took six days in all. Hence, Vinland, if beyond Labrador, must be sought for in Newfoundland, either in one of the shallow inlets near the Island of Belleisle, or in some place along the northwest coast of that island. The fact that grapes are found there, according to Anspach, lends some weight to this view. It is possible, too, that the Naskapi, sometimes found in Newfoundland and resembling the Eskimos in many respects, may have been included under the name Skraellings by the Northmen. It is clear that, like Greenland, Vinland the Good was a fraud on emigrants ; that the stories as to ship-loads of grapes, self-sown fields of wheat, genial winter weather, etc., were the productions of Eric's prolific brain ; and that we must first succeed in finding Greenland's verdant mountains before we can hope to discover the vine-clad hills of Vinland the Good. II. The Colony of Terra Nova, or the " Land of the Corte Reals." — The history of European colonization north of Florida has been hitherto supposed to have begun at the commencement of the seventeenth century, except perhaps a small English settlement at St. John's, Newfoundland. It has not hitherto been known to historians LOST COLONIES OF NORTHMEN AND PORTUGUESE. 47 that the eastern portion of British North America was the first part of the New World that was constituted a colony, that from 1500 to 1579 commissions were regularly issued to the Corte Reals as governors of Terra Nova, and that by virtue of this claim on the part of the Portu- guese at least three settlements were made by the Portuguese them- selves, and later by the Spaniards (after they had annexed Portugal), one of these colonies being the earliest European settlement in North America after the discovery of the New World by Cabot. A flood of light has been shed upon this early colonization by Senhor Ernesto do Canto, of San Miguel, Azores, whose most recent publica- tion on early Portuguese exploration consists mainly of a selection of documents connected with the family of the Corte Reals, the explor- ers and first governors of Northeastern America. The information contained in Senhor do Canto's work enables me to claim for the northeastern parts of America almost a century of his- torical existence prior to the seventeenth century. This colony, em- bracing Labrador, Newfoundland, and Nova Scotia, and, under the grant to Fagundes, probably a large portion on the east coast of the present United States, was far the earliest European colony (except- ing perhaps Vinland) not only in North America, but also in the New World, for the commissions of the Corte Reals date in regular succession from 1500 (i. e., two years after America had been dis- covered by Columbus, and six years after its discovery by Cabot) until 1579, soon after which Portugal and its possessions were annexed to Spain. This colony of the Corte Reals was not merely a nominal one, for in the course of the sixteenth century the Portuguese made a settle- ment in Cape Breton in 1521, and another in 1567, while the Spaniards ■ — their successors — sent a third to the same country. Of these three colonies little or nothing is known ; even the colony of Terra Nova has lost its place in history, which begins the annals of British North America a century later with the arrival of French settlers in La Nou- velle France. In 1500 Gaspar Corte Real explored the coast of Labrador, proba- bly nearly as far north as Hudson Strait, and also Newfoundland and Nova Scotia. He brought back several of the natives, who resembled the present Micmac Indians. He went there again, in 1501, with three vessels, but that in which he sailed never returned. In 1502 his brother, Miguel, sailed in search of Gaspar, and met with the same fate. Again, in 1503, an expedition was sent out to try to get some tidings of the two gallant brothers, but without success, and the king, discouraged by these disasters, refused to allow Vasco Annes, the elder brother, and one of the ornaments of his court, to continue the search. In early charts of this continent the Portuguese flag is frequently represented as waving over Labrador, Newfoundland (Bacealaos), and 48 THE POPULAR SCIENCE MONTHLY. Nova Scotia, which were sometimes described as the " Land of the Corte Reals," and as the " country discovered by Joao Alvares." We now know that the person to whom these Christian names belonged was Joao Alvares Fagundes, who early in the sixteenth cent- ury carried on explorations in Northeastern America, and who, in 1521, had a grant of the country between the land of the Corte Reals and the northern boundary of the Spanish colonies, including the " terra firma and islands " discovered by him, a grant which for the first time included a portion of the United States. Traditions as to an early settlement still linger among the Mic- macs, who aver that certain earth-mounds at St. Peter's, Cape Breton, were built by white men before the arrival of the French. This be- lief received many years ago a confirmation by the discovery in one of these mounds of an archaic cannon formed of bars of iron fastened with iron bands or hoops, those toward the breech being the strong- est. This gun attracted little attention at the time, and was broken up. My knowledge of this circumstance is derived from the historian of that province,* who for more than twenty years was on circuit in Cape Breton once, if not twice, a year. He frequently spoke of the enigma, and regretted the stupidity and utter want of interest which prevailed at that time with respect to the early history of the country. An inquiry into the date of the manufacture of such guns showed clearly that it must have been brought out before the arrival of the French in Cape Breton, f Were these remains at St. Peter's vestiges of this early Portuguese colony ? From a rare pamphlet, " Tractado das Ilhas Novas," by Francisco de Sousa, written in 1570, and published at San Miguel in 1877, Senhor do Canto, in his " Os Corte-Reaes " (pp. 89-93) copies an account of the colony in question, and has also given us a description of the dis- coveries, and a copy of the commission of Joao Alvares Fagundes. It appears from this that the colony was planned by some noble- men at Viana, consequent upon the discoveries made by Joao Alvares Fagundes. They sent out a ship and a caravel, but Newfoundland (Baccalaos) having been found too cold, the settlers sailed to the west and southwest, and, having lost their ships, were obliged to remain. News was subsequently received from them through Biscayans, who were then in the habit of frequenting that coast. They asked for priests ; said that the natives were well disposed ; and that the coun- try produced " nuts, chestnuts, grapes, and other fruits, showing the goodness of the soil." Allusions in early writers point to the existence of this early Portu- guese colony. Anthony Parkhurst, in a letter published in 1578, when speaking of the excellent timber in Cape Breton, says : " I could not * Judge Haliburton, the author's father. f The article " Artillery," in the " Encyclopaedia Britannica," says that such guns were made from 1500 to 1545, when cast-iron guns were first introduced. LOST COLONIES OF NORTHMEN AND PORTUGUESE. 49 find it in my heart to make proof whether it be true or no, that I have read, and heard, of Frenchmen and Portugals to be in that river" (the St. Lawrence) " and about Cape Breton. If I had not been deceived by the vile Portuguese descending of the Jews and the Judas kind, I had not failed to have searched that river and the coast of Cape Bre- ton which might have been found out to have benefitted our country." The colony of Fagundes of 1521 has been unknown to historians, though the circumstances that led to the attempt to colonize Terra Nova have not escaped attention. Fagundes had already been an ex- plorer, and his name is connected with the northeast coast of America by early charts, while his discoveries, as we have seen, are referred to in his commission. We also meet with a probable reference to this colony in connection with the cattle and swTine which Champlain (1618) says "were left there " (Sable Island) " more than sixty years ago " (i. e., before 1558) by the Portuguese. In Haies's report of the voyage of Sir Humphrey Gilbert, given by Hakluyt, and probably written about 1583, he says, " Sablon lyeth about twenty-five leagues to the seaward of Cape Breton, whither we were determined to go upon intelligence wre had of a Port- ugal during our abode at St John's, who was himself present when the Portuguese (about thirty years past) did put on the said island both neat and swine to breed, which were since exceedingly multiply- ing." It appears that the Baron de Lery, in 1518, landed some cattle at Canso, and the remainder on Sable Island, on his abandoning his inten- tion of forming a settlement in Nova Scotia. It seems also probable that the Portuguese must for the same reasons have landed their cattle at Sable Island, and that the date is the probable time when the settle- ment of Fagundes was broken up. III. A Portuguese Settlement at Inganish, Cape Breton, 1567. — De Laet (book ii, chapter v) tells us that the Portuguese placed Port Ningani from eighteen to twenty leagues to the northwest of the cape which afterward gave its name to the Island Cape Breton, " where they formerly had a settlement, which they have since aban- doned." Champlain says that the Portuguese were forced to do this by the cold and rigorous climate. Until recently this was all we knew about this colony, but Senhor E. do Canto has now discovered a MS. charter in the Torre do Tombo, at Lisbon, from which it appears that the king, on May 4, 1567, ap- pointed Manuel Corte Real notary public of a colony about to be founded in Terra Nova, and for which two ships and a caravel were then about to start from Terceira. In 1579 the captaincy of that colony was conferred upon Vasco Annes, the fourth in succession of the Corte Reals. The author of the " Tractado das Ilhas Novas" ap- pears to have sailed with the expedition of 1567, and it is quite clear that up till then no tidings from the colony founded by Fagundes had VOL. XXVII. — 4 5o THE POPULAR SCIENCE MONTHLY. been received. It is also clear that a Portuguese colony existed for some time at Inganish, which was abandoned on account of the cold. Was Inganish the site also of Fagundes's colony, as well as of the settlement made in 1567? It seems improbable that the colony of 1521, cut off from all communication from the mother-country for half a century, should have survived until 1567, and we are forced to conclude that the cattle and swine left on Sable Island in 1553 were the property of the Fagundes colonists, who had abandoned their settlements. It seems clear, at the same time, that the colonists who sailed in 1567 were aware that Fagundes had found Newfound- land too cold for a settlement, and had given the preference to Cape Breton. We must assume, therefore, that the colonists of 1567 settled some place in Cape Breton or Nova Scotia. Champlain says the Port- uguese abandoned their settlement at Ningani (Inganish) on account of the cold. A Portuguese gentleman informed me last winter that there existed a tradition at Viana that the colony of Terra Nova was sold to the English on account of the cold climate. Senhor do Canto refers to a similar tradition, but applies it to the colony of 1521, in- stead of to that of 1567. This 6ale must have taken place after 1567, for otherwise the Portuguese, having sold out their rights to the Eng- lish, would hardly have attempted, after the transfer, to make a settle- ment in that country. IV. A Spanish Settlement at Sydney, Cape Breton (Spanish Harbor), between 1580-'97. — We are told that in the seventeenth cent- ury Louisburg (called English Harbor) was frequented by the Eng- lish fishermen ; St Ann's by the French ; and Spanish Harbor by the Spaniards. Why was Sydney — at one time known as Spanish Harbor — the favorite resort of Spanish fishermen ? About the time Fagundes sailed to Cape Breton, the Spaniards seemed to question his right to that country, as appears from the Spanish map of 1527, where the Spanish line of demarkation includes Cape Breton and Nova Scotia, leaving Newfoundland to the Portuguese. It is probable, however, that the Spaniards did not practically question the claims of the Portu- guese, which were specially guarded in commissions to Spanish explor- ers. In 1580, however, the question was settled by the annexation of Portugal and its dominions by Spain. We know that toward the close of the sixteenth century a Spanish colony was sent to Cape Breton, and we can assume that it sailed some time after 1580. Our only account of it is a melancholy one, for Charlevoix says that the forty poor wretches whom the Marquis de la Roche left on Sable Island (1598) "found on the sea-shore some wrecks of vessels, out of which they built barracks to protect themselves. They were the remains of fyatiish vessels which had sailed to settle Cape Breton." Any one who has seen the wreck-strewed coast of Sable Island must remember it as suggesting a graveyard of vessels. Those that have been there a few years are soon covered by the drifting sands, and the half-buried skeletons of RELIGION WITHOUT DOGMA. 51 later wrecks are to be counted by the dozen, in different stages of sepulture and decay. It is probable, therefore, that these wrecks, which were used by the French convicts, can not have been there many years previously. The date, therefore, of this Spanish expedition to Cape Breton must have been between 1580 and 1598. An inlet in Sydney Harbor is still known as the " Northwest Arm of Spanish River." We have no account of the fate of this colony, but we may infer that it only existed for a short time. The French took possession of and colonized that country early in the seventeenth century, and their writers are silent as to the existence of any Spanish settlement there at that time. So thoroughly forgotten is this lost colony of Terra Nova that, though there are many Portuguese names that survive on the map of Northeastern America, they no longer suggest their origin or meaning. Few persons imagine that the Bay of Fundy is the "Deep Bay," or Baya Fonda ; or that Cape Race means the " Bare Cape " or Cabo raso. The "Land of the Corte Reals" knows them no more. ■♦»» RELIGION WITHOUT DOGMA.* By GEOEGE 1LES. "~VyO purpose in the study of history is more instructive than that by -LN which we trace the progress of freedom against authority, of in- quiry as opposed to dogmatic assertion, of reason and right against arbitrary power. As I shall have frequent need to speak of authority, it may be well to discriminate between its various species, and state with what specific meaning the term is to be used in this discourse. In the instruction of the young we all admit that authority must be the principal method employed. In early years many lessons were taught us chiefly on that principle — the rules of arithmetic, the relations of geometry, the for- mulas of logic, the rudiments of physics, with sundry theories as to the fluid nature of electricity and the atomic structure of matter. Besides these were lessons in history, which included the statement that Charles I was a martyr ; and lastly the Church Catechism — all these did we diligently commit to memory and regard as truth. With the lapse of years came the perception that the lessons of childhood and youth were not all of equal validity. The mathematics and logic which appealed to the understanding remained, so did the largest part of physics ; the hypothetic nature of electricity, however, and of the ultimate structure of matter, being deemed something else than cer- * A lecture delivered at Montreal, Sunday, March 30, 1884. 52 THE POPULAR SCIENCE MONTHLY. tain. Our views of history underwent some change, and Charles I was removed from our roll of the army of martyrs. The revered sen- tences of the Catechism, which so tersely told the origin and destiny of all things, the nature and intentions of the Supreme Cause, were sub- mitted to tests which left them of somewhat less force than of old. The maturing powers of reason passed judgment on the authorities, left some of them undisputed, regarded others as approaching correct- ness with more or less probability, and placed others, again, in the category of unsupported assertion. As a typical case of allowable and legitimate authority, let us take the statement by Dr. Tyndall, that watery vapor, suspended in the at- mosphere, acts as a powerful absorbent of heat radiant from the earth. We accept the statement because it is undisputed by physicists who are competent to execute tests of it, and because, should we choose to become instructed in the methods of research which Dr. Tyndall employs, we could verify his conclusions as many inquirers have done. Genuine authority gives us proofs, it predicts, and fulfillment follows : The geologist declares that certain strata may be coal-bearing ; we sink a shaft and find the fuel. The meteorologist forecasts the weather twenty-four hours ahead, and the skies verify his prognostications. Venus, we are told from the observatory, is to cross the solar disk at a specified time, and punctually to the instant the planet appears. Fi-om elaborate consideration of the molecular groupings of certain com- pounds of carbon, a German chemist thought that a substance which he sought to build up from its elements would possess great beauty and value as a dye-stuff. Success rewarded his patient labor, and a new hue was placed at the disposal of the textile manufacturer. The kind of authority which men of scientific achievement exert, and which all men of special gifts of talent and character enjoy, is an authority to which we owe intelligent and cheerful allegiance. The world ad- vances by leadership of this kind and by loyalty to such leadership. But, when a theologian says that the world was made from nothing, that man was created from the dust of the earth by instantaneous fiat, and then caused to be tempted to his fall — when we find all these assumptions made the basis of an elaborate and definite scheme of supernatural theology — we confront what seems to us the authority of unproved assertion, which reason questions and science ignores. The history of every thinking man, in his separation of the authori- ties contending around him for obedience into valid and invalid, is a summary in some sort of the history of the race in its gradual emanci- pation from dictatorship in science, in the state, and in theology. The records of science show us the common case where men of extraordi- nary genius have risen so high above their fellows as to excite reverence for their results, rather than emulation of their methods. The price paid by mankind for towering ability has often been the production of generations of mere quoters and commentators, who revered the RELIGION WITHOUT DOGMA. 53 work of a master as too sacred to require addition or improvement. Ptolemy's system of the universe was so great an advance on the ex- planations which preceded it, that for sixteen dreary centuries it was imposed upon students of the heavens. Not until the time of Coper- nicus was the theory established that the sun is the center of our sys- tem, as against the notion that the sun and planets revolve around the earth. Aristotle had such a wonderful grasp of mind, had so compre- hensive knowledge, and was a man of so much constructive genius, that admiration of him paralyzed research in science for nearly two thousand years. Whewell, the historian of the inductive sciences, shows how Aristotle's Hellenic love of symmetry in thought led him to bridge gaps in evidence and induction by verbal propositions. His works presented a fictitious completeness which imposed upon students for ages. Mere comment and expansion gave place to original work only when Bacon, Galileo, and others like them, taught that the way to know Nature was to observe, experiment, and generalize. When the methods of Aristotle and Ptolemy as observers were imitated, and when their results ceased to be echoed, Avas science born again, to achieve wonderful victories ; then the goose-step of the schoolmen became the onward march of exploration. The revolt against the predominance of classical education in favor of that of science is a noteworthy sign of the times. Greek and Latin literatures used to be held to furnish a mental training obtainable by no other studies. Now the dominion of words is pass- ing away. In technical schools and colleges students are brought into direct contact with the facts of Nature, and are taught how to interpret these facts into principles. It is becoming more and more widely held that the ancient literatures only provided a gymnasium for the mind, exercise wherein can be profitably superseded and included by that afforded in the tasks of the laboratory, the workshops or the botanic field. Instead of repeating Greek prose and verse, the student of science is taught skill in the use of his senses and reasoning powers, it being intended that he shall so acquire knowledge as to be able to add to knowledge. As in the history of science and education, so in that of the state, has authority declined before the spread of the love of freedom. The history of European and American civilization is the history of the gradual recognition of the individual's rights, as against the claims of monarchy and aristocracy, of privileged persons, families, and classes. And, however imperfectly democracy may fulfill the expectations of its advocates, through freedom having often come before education in responsibility, one thing is clear, its idea is better than those which it has displaced — the idea that, as each individual man has duties to the state, he has correlative rights which entitle him to a voice in appoint- ing those who make the laws and execute them. In its advance from authority to freedom, the history of Christian 54 THE POPULAR SCIENCE MONTHLY. theology supplies a parallel to that of science and that of the state. Christianity, based on the claim of its 'founder to be the Lord and Saviour of men, finds its strongest and most consistent exponent in the Roman Catholic Church. That Church presents its dogmas with absolute claims to truth and infallibility, and demands the complete submission of mind and will, as the representative on earth of the Divine Saviour. The yoke of this Church, though firmly fixed about the necks of its followers, grew so burdensome at last that the Refor- mation arose, and belief was transferred by millions of men from the infallible Church to an infallible book, which book, however, was to be interpreted in the light of private judgment. While the ecclesiastical government of Rome was discarded, much of its creed was retained ; and to this day Protestantism, in its ritualistic and more authoritative forms, is scarcely to be distinguished from its parent. Dissatisfied with the Bible as an infallible standard of faith and morals, the Lib- eral Churches have discarded it from its place of supreme authority and accept Christ as spiritual Lord and teacher. The Liberal fold in turn has developed a school of much influence, which, unable to bow to any external guide, looks within and finds in intuition direction sufficient for spiritual life. The history of Christianity, from the time of the apostles to that of Theodore Parker, manifests first the gradual evolution of authority, and then tells us how by abusing its power and becoming corrupt and arbitrary it incited the rebellion of bold and free men, who point by point have taken the citadels of assertion and dogma. Theology proves on examination to be no more than the views of Nature entertained by observers in the remote past. These views, formulated into creeds and crystallized into institutions, have established churches, ruled not less by the love of power than by the desire to do good. The church-makers, in a very different spirit from that of men of science, have not dealt directly with facts, but with opinions about facts, and on examination it would appear that they have proceeded on some erroneous lines. In refusing competency to the intellect in its attempt at dealing with the problems of life, the theologians have on another hand overrated the powers of this same intellect. While affirming the supreme mystery which infolds the universe, they have inconsistently given verbal explanations of that mystery. In the same page which speaks of the untrust worthiness and weakness of the human mind, we may find a full account of the origin and des- tiny of all things, and an analysis of the Divine nature and intention. The depreciation of human ability and the need of modesty in attack- ing the great questions of life and death are stated very forcibly, and thereupon solutions are offered us of all that a little before was de- clared inscrutable. In endeavoring to rise from Nature to a concep- tion of a creating and ruling spirit, different in character from what observation of Nature would lead us to imagine that spirit to be, the- RELIGION WITHOUT DOGMA. 55 ology has become involved in endless contradictions. The Christian idea of the Deity would seem to have been developed in the light of the sympathies which have arisen in the domestic and social life of man. These sympathies with their allied sentiments have been un- warrantably projected out beyond their proper sphere, that of human affairs, into an idea of the Divine — it being forgotten in the process that Nature in the broad view is the fullest manifestation of divine power we know, and that from Nature herself in her manifold opera- tions should we try to integrate a conception of its informing Spirit. Hence the discrepancy between the conception of the theological Deity and the facts of the universe. Do the processes of Nature exhibit sympathy, mercy, or love ? Or do we not rather observe in them the uniformity of a power manifested through an infinite mechanism which neither excuses ignorance nor spares weakness ? Yet so widely and in our view so unjustifiably have the ideas of God and Nature diverged, that we find Tennyson asking, as he depicts the agony of the struggle for existence and the profuse waste of organic life, " Are God and Nature then, at strife ? " Any theory of the universe which en- deavors to be comprehensive must subdue the impulses of sentiment and emotion and face all the facts of experience. The natural order shows us redundant life as necessary for the competition whereby the fittest individuals and species may survive and advance. The fittest may not from the human stand-point always be the best or the highest, for the parasite, protected from contest in the stomach of a man or horse, may degenerate and assume a type lower than that in which its existence began. The system of prey, the thousands of species of para- sites which make the days of so many nobler types of life miserable and short — all this does the natural order include, no less than the cul- minations of human consciousness, genius, and conscience which thrill us with their power as if we stood in the very presence of the Divine. Nature presents to our view and study a mechanism of infinite com- plexity. Its rules of action we may know in part, and, when we obey that knowledge, happiness can be ours ; but, however diligent we may be in study or willing in our obedience, all its laws we can never dis- cern, and its wheels may seize us and painfully mar or quench our lives at any moment — the lurking germs of disease by inheritance within us, or floating in the air around us, the incalculable forces of earth- quake or tornado ; the liabilities incidental to modern locomotion, and many of the processes of modern industry. These, together with the willful exertion of human malignity, all beset us as subtractions from joy in life. Our sympathies, baffled in their endeavor to find scope be- yond the limits of human relations, return thither to their source, as perhaps to the sole legitimate sphere for their exercise. Humanity re- mains, though the supreme cause continue undefined. In the spirit of much of what the theologians say, we find ourselves acknowledging our inability to rise from phenomena to ultimate cause or essence. 5 6 THE POPULAR SCIENCE MONTHLY. Declining to attempt solutions of the origin and destiny of the uni- verse, we would endeavor to attack undone work for mankind near at hand, neglecting in the mean time all discussion of the remote and im- possible. Not only in their overrating the powers of the intellect did our forefathers err, but also as seriously in their views of knowable truth did they exhibit immaturity of thought. Truth may be defined as the reality of things underlying our partial knowledge of them. Except in the limited area of axiom, our knowledge is imperfect and incom- plete. On examination, it proves to consist largely of mere signs and symbols. We can state the law whereby gravitation acts, but the force itself eludes our scrutiny. We can formulate its rate and measure its quantity, but why bodies tend toward each other throughout universal Nature is as little known to our acutest physicists as to the least in- formed savages. All analogy requires us to think that a medium is necessary for the conveyance of the attraction, yet, if there be a me- dium, how does it do its work, and that too across the diameter of the visible universe with practical instantaneity ? So too with the proper- ties of substances which are surely among the simplest things we can consider. What is the essential difference between iron and lead, and why does water always freeze in six-petaled crystals ? Such questions, which lie at the very threshold of the temple of inquiry, show us how hard is our task of getting below our labels, our names of things, and pursuing investigation more than a single remove from appearance. At the risk of being tedious, I shall take an example of the growth of our information about a single substance, to illustrate the indefi- nitely great extensions of knowledge which are possible to us, in every direction in which we may seek it — this in contrast with the views of knowable truth which were current in the infancy of information. Iron had, doubtless, in very remote times, been observed to be tena- cious and malleable ; of value, therefore, in making of tools and weapons. Later on its magnetism was noticed, and, at some uncertain date, in China probably, it began to be used in navigation as the mari- ner's compass. The rusting of the metal must have been observed very long ago ; yet it is little more than a century since that com- mon fact was rationally explained, and since the chemical relations of iron began to be studied. Examination has determined its crystalline structure ; its capacity as a transmitter of sound, heat, and electricity ; and its improved tenacity, when united with carbon, to form steel. The long catalogue of its various properties does not seem to be ap- proaching a limit, but rather the reverse. Within recent years spec- trum analysis has determined the peculiar lines, several hundred in number, which enable it to be identified as a fiery vapor, alike in the flame of the laboratory or in the remote orbs of space. The telephone proves that a small disk of the metal conceals within its structure the subtile means of converting sound-waves into electrical tremors, and RELIGION WITHOUT DOGMA. 57 these back again into audible vibrations, with so much of the indi- vidual tone of a speaker as to be readily recognizable. Now, if iron, which is comparatively so simple a thing, presents such a multitude of properties and powers, if it be shown to have relations with all else in Nature, if very important knowledge respecting it has but recently come into our possession, how very cautiously should we proceed when our subject of thought is not a chemical element, but, say, some large question of human nature or public policy ! The little gray crystal of iron is eloquent in bidding us have some decent hesitation, when we are considering, say, some proposed legislation which is to affect the complex sentiments, desires, and passions of men. For lack of that decent hesitation, statute-books are filled with laws which are evaded, or work results opposed to those expected from them, all tending to establish in the popular mind an injurious contradiction between law and common sense. And what supreme diffidence should there be when we are endeavoring to arrive at, not some knowledge in a special science, not the best policy in a matter of law or state, but when we approach the highest questions : How best can we interpret Nature so as to form a conception of its informing sph'it ? If a man die, shall he live again ? What are the sanctions and what the standard of right conduct? Which is the higher reverence, that which accepts the dictum of a local and arbitrary authority in response to these ques- tions, or that which considers them patiently in the light of all human experience to the present day, by the aid of the highest faculties we possess ? We are often told to bow to authority in the singular, but we are surrounded not by authority but by authorities, many and diverse. Among them all — religious, social, or scientific — we can but lean on such common sense as we possess to aid us in selection and discipleship. I have defined truth to be the reality of things underlying our par- tial knowledge of them. Our forefathers thought of truth as a thing which they might grasp as fully and perfectly as a child's hand in- closes a pebble ; our conception is of something which we may ap- proach, but never possess, save in the restricted field of axiom. We think of truth as of the dim face of a star, discerned through difficulties of distance, distortions of media, and defects of the seeing eye. The old view of finality, completeness, and perfection in knowledge, we discard as utterly disproved by fact. Science knows nothing of the infallibilities it was aforetime thought necessary to assume. The in- fallible standards of Church, Bible, and intuition have never yielded to inquiry more than the verbal husk of assumed certainty. Science accepts the risks of a fallibility which can not be escaped, but which it reduces to a minimum by the co-operation of many minds. The desire to be certain, which set up the oracles and established the suc- cessive infallibilities is, however, an intelligible desire. Doubt and ignorance are not pleasant states of mind to acknowledge, and the 5 8 THE POPULAR SCIENCE MONTHLY. process of arriving at fair judgments is both laborious and painful. Instead, however, of assuming certainty because it is desirable, we would endeavor to earn it, by recognizing it as every man's duty and privilege to add to truth, in the justness, completeness, and clearness of his knowledge of it. And, since the scope of the unknown is infi- nite, the incitement to the fulfillment of this duty is full of hope and promise. Science, unlike dogma, does not point to fields harvested and gleaned long ago, but to continents awaiting their Columbus — to pressing problems of individual, social, and political life demanding solutions by thoughtful men. And, in the fields of scientific investiga- tion, we can see how every newly ascertained fact and law extends the horizon of Nature, adds to the area of unexplored territory, thereby stimulating the student to achievement therein. In researches re- specting mind and brain, and their relations, in probing conscious- ness to its depths, and in the results which may follow the inquiry as to whether the intellect does or does not come into direct contact with external Nature, some of the ablest thinkers of our time place hope of more light on the chief problems of life. Our conception, then, of knowledge leads us back to the early similitude which likened it to a tree. Knowledge does not increase, like a honey-comb, cell simply added to cell, but, like an oak, whose every year of growth implies not addition merely, but vital transformation of structure. Nothing is fixed but the axis from which the branches and boughs spread out, as if they felt they had all the universe for their expan- sion. A stripling oak of a few seasons' growth is beautiful enough in its way ; but would it be wise or useful to uproot it, shelve it in a museum, and declare it to represent a finality as to oak- possi- bilities ? The idea of knowledge which I have sought to express makes clear the grounds whereon thought and discussion ask for full liberty. As men differing in natural ability, temperament, education, and stand-point, strive to attain views of truth, their results must inevita- bly vary. "Recognition of difference of view" we would, then, sub- stitute for the offensive term " toleration of dissent," which latter phrase, from one who holds that he possesses finality, simply means the permission of known error, which he may be unwilling or un- able to punish. And the differences of view which men of opposite temperaments and tendencies may entertain are often mutually com- pleting, and become indued in a master-mind with stereoscopic relief and unity. Let me cite an example of this : Two schools of thought endeavored to explain conscience on different principles. The one held it to arise from an innate moral sense, the other from the results of experience. The philosophy of evolution includes in its explana- tion both series of facts from which these two schools argued. It shows how ancestral experiences of right and wrong conduct become organized in the race, and are transmitted as moral tendencies to off- RELIGION WITHOUT DOGMA. 59 spring. These tendencies are advanced in their progress a step by the experience of each individual life. Having, then, expressed our dissatisfaction with the method of theo- logical authority, from its having attempted problems which as yet are beyond the scope of the human intellect, and because of its erro- neous notions as to the knowability of truth, let us endeavor to describe the method of science which we would adopt in the whole sphere of our mental activity. The scientific method is nothing very new or unfamiliar ; it is simply ordinary thinking, corrected by the canons of a more exact and cautious procedure. It is organized, com- mon sense coming into contact with fact, and carefully sifting the evidence derived from fact. Business men employ it in importing or manufacturing their wares, in estimating the demands of markets, and ascertaining the standing of their employes and customers. Physi- cians act according to it in diagnosing their cases, prescribing treat- ment, or operating in surgery. Lawyers employ it in supporting their pleas and arguments ; and judges use it in rendering their decisions within the limits of the written law and of their precedents. The sci- entific method ignores no faculty of man or fact in Nature ; it recog- nizes to the full our emotions, affections, and sentiments, but subordi- nates all these to the intellect, whose dictum alone is given command over the educated will. Authority relies on inspiration, revelation, the miraculous, and the supernatural ; science relies on brain, on experi- ence, the mastery of facts by accurate and patient thought. The one receives or imagines it receives, the other acquires and has no opinion not subject to revision as new evidence comes in. It entertains no beliefs beyond evidence, and seeks none. It knows nothing of infal- lible guides without or within, nothing of authorities which may not be doubted and which submit no proof of their assertions. Science endeavors to substitute convictions for mere assent ; and, instead of mechanical adhesion, would give to genuine authority the intelligent concurrence earned by the labor of the individual mind. It is not because science has won its chief victories in the physical world, where the comparative simplicity of its problems has invited attack, that we should therefore have an imperfect idea of its scope. Its scope includes the whole range of human thought and feeling. Science is not limited to fields where clocks and micrometers may be used to measure, or logarithmic tables be employed to compute ; it recognizes human emotions, sentiments, and will. To these it would direct study, no less than to the areas where exact results are attainable. Applying, then, the method of science to an examination of the- ology, it appears to consist in an attempt at explaining the facts of Nature, and the sanctions of duty, in distant ages of scant knowledge. Its scriptural revelations come down to us through centuries of untrust- worthy custodians, and when they reach us at last they are not reve- lations to us, but hearsay about revelations, and must be judged by the 60 THE POPULAR SCIENCE MONTHLY. canons of criticism which we apply to other departments of literature. Every theology, no matter how emphatic its assertion of a supernatural source, bears about it the plain marks of its human origin. The con- ceptions of God vary with the zones and closely parallel the grades of culture in which they arise. The commandments called divine become more elevated as the civilization of a people advances. The disciples of a prophet or apostle direct the noble impulses he has implanted in their hearts to broaden his teachings and correct his errors. Contrast the almost human tribal God of Abraham, Isaac, and Jacob with the lofty idea of the Deity entertained by Isaiah. Compare this latter, again, with the universal Father whom Jesus taught his followers to worship. Mark the cumbrous legality and ritualism of the Old Tes- tament and its silence respecting the future life ; how different this from the teaching of Jesus, who exalted the spirit above the letter, valued love more than sacrifice, and assured his hearers of an immor- tality which made this world but a temporary scene of trial and pro- bation ! Note how the high-minded Paul saw nothing reprehensible in slavery, and compare that with the humanity of an age which gives even dumb animals rights against their owners. The evolution of thought in general is fully exemplified by thought in theology, not- withstanding its assertion of a sacred fixity. John Wesley, sensible man that he was, said that, if he were to give up his faith in witch- craft, he would give up the Bible. Yet his followers have dropped the witchcraft, and kept the Bible. No study of human history would be valuable or just which did not recognize as a prime fact the profound religious instincts of our race. The awe inspired by the sublimity of the starry heavens, and the terrible and resistless forces of Nature — those of the volcano, the tempest, the pestilence so mysterious in its origin and spread, and the famines so devastating in the childhood of races — all these, not less than the kindly succession of the seasons, and the enjoyments of health and home, have suggested an infinite Power, the immanent sustaining spirit of universal life. The baffled hopes and aspirations of the soul, the anguish of bereaved affection, the enigmas and trage- dies of life, have joined together to implant a faith in another life which shall be complement and compensation for this. As a record of man's perception of his helplessness in the combat with Nature, as a pathetic registration of his hope, fear, and remorse, the religious sentiment is entitled to our profound respect. Every sentiment, how- ever, of the human heart, while compelling our respect or reverence in itself, awakens some less lofty feeling by its expression in institu- tions. The Sanhedrims and Councils of the churches, which have arisen by virtue of the religious sentiments of our race, do not appear to have been lifted above the passions and partialities of our Congresses and Parliaments. The inner heart of humility and reverence in relig- ion we highly respect, but the churches not so highly. The inevitable RELIGION WITHOUT DOGMA. 61 loss which attends the translation of sentiment into organization may perhaps be exemplified in the case of our instinct for justice. That instinct, one with the love of truth, in its expression as a means of self-protection against wrong, has given rise to law and the courts. Are the results of their processes such as to awaken the reverence which the sentiment of justice compels? The discrepancy between religious feeling and ecclesiasticism ; the love of right and law, as practically enacted and executed, suggests the parallel gap which philosophers and poets have so often mourned — the gulf between thought and language, which leaves music to suggest much that in speech must remain inarticulate. The great artists of the world, whose masterpieces fill the generations with wonder, have lamented how far execution has lagged behind conception. The supreme dram- atist does not seem to have thought his work sufficiently valuable to take any special care to hand it down to posterity. Religious feeling by its arrival at the theistic idea has done man- kind incalculable service. How potent the thought that the universe is one, and represents one uncontradicted will ! How influential for good the thought that a Supreme Mind, too great to be deceived, and absolutely righteous, knows every thought and act ! " Thou God seest me," has, I think, restrained evil in the mind of conscientious theists, with a directness which might have been denied to reflections as to consequence. It is not because some of us may be dissatisfied with theology that we fail to recognize its value in the past and present. Associated with moral codes, it has impressed them on minds unfit by immaturity for the responsibilities of freedom, and by dogmatic force has doubtless given stability to order. Not because the Gods of the sects seem crude and imperfect conceptions are we to expect that the religious feeling which gave rise to all these will die out in man. It will, I believe, from age to age, go on endeavoring to form a theory which shall explain the facts of human life and universal Nature, which shall impress the imagination and influence the will. One result of science will be profoundly influential here — its arrival at the idea of Law, its perception of uniformity and constancy in Na- ture ; the proof which, in large part, it now possesses, that the history of the universe, from nebular mist to man, illustrates causation and continuity. This idea, excluding as it does the miraculous and the supernatural, leads us to regard the history of the universe as an un- broken and consistent unfolding. In this view, every item of knowl- edge we attain is secure from any interference from break in the natural order. We are incited to explore relations which are un- changeable. The sense of supreme mystery will grow as the margin of the known expands and touches larger and larger circles of the un- known ; but any territory we may win we will feel sure of retaining. And, although our knowledge may not be either wide or deep, still much of it will doubtless be regarded as valuable and important 62 THE POPULAR SCIENCE MONTHLY. throughout the future of our race. The laws of gravitation and evo- lution may he included by the coming man in wider generalizations, but we can scarcely conceive their being ever regarded as other than immovable and fundamental portions of truth. We are not of those who say that human knowledge is only relative to the individual con- sciousness, and therefore shadowy and invalid. With reverence be it said, we hold that such knowledge as we have of water or iron, to be a part, however infinitesimal, of the divine knowledge of these things. The instituted religions have not only given us the theistic idea, but have also laid us under weighty obligations by establishing the only means of formal instruction in morals known to our race. And here let us note the damage caused by the accidental association of a moral code with a cosmogony developed in early stages of knowledge. It is not because Genesis gives an unsatisfactory account of the world's beginning, that the decalogue does not validly register the dictates of human experience, taking form in the brain of a great lawgiver. The Mosaic and all other authoritative codes of conduct, as currently held to-day, are supported by appeals to experience ; then it becomes the mission of competent thinkers to revise these codes in the light of all that men have thought and done to date. It becomes the duty of science to investigate the conditions of happiness, which we must morally fulfill if we want happiness ; no other standard of conduct do we know than this. For the essence of religion, the faith that the right will win, and that we should help it to win, we are indebted to Christianity in its rationalized forms, and for that faith we thank it. But the churches have done more than preach theism and teach morality — they have endeavored to imitate their Founder in his care for the desolate and oppressed. Countless kind and tender spirits have found in the noble philanthropies of Christianity scope for their charity and mercy. Here, as elsewhere, we do not propose, in our in- dependence, to disinherit ourselves of anything of value which Chris- tianity can give. The scientific conceptions of duty at which we seek to arrive are to be broadened and deepened by the sympathies which yield the highest satisfactions of man. The necessity for the greater recognition of this element in conduct was never so urgent as now. The masses of mankind born into a world abounding with pain and evil have hitherto been disposed to consider their burdens as all equally providential. They are, however, now beginning to distin- guish among the ills which beset them. Some they regard as inevi- table, to be borne with manly courage ; others, again, as infractions of justice, preventable or remediable by proper means. There is no prev- alent recoil from the disciplines of home and business life, but there is wide-spread and growing discontent at the extreme inequalities of for- tune— inequalities held to be the result of bad laws, unwise customs, and downright dishonesty. The enormous sale of Mr. Henry George's A SCIENTIFIC VIEW OF THE COAL QUESTION. 63 books is not, I take it, due to any popular faith that the remedy he proposes — the public confiscation of land — will right the wrongs of poverty. The consciences of the people are shocked at the immorality of the proposal. Mr. George's vast audience is attentive because he states very forcibly the anxieties and dangers which beset bread- winners amid the contingencies of the modern industrial world. When, from beyond the sea, we hear of nihilistic vengeance, social- istic uprising, and dynamite plotting, it would seem that the safe- guards of civilization against a relapse into barbarism are less secure than is commonly imagined. Do not all these dangers spring from lack of sympathy between plenty and want ? Not simply between plenty and want in matters of goods and chattels, but in the better things of culture and refinement. The generous man who will correct with kindness the faulty arguments of a neighbor less endowed than himself, who will cultivate in the youth of his acquaintance love of literature, of art, and of the natural sciences, is doing as much to strengthen the bonds of society as when he shares his income with the destitute and forsaken. When I was in Ireland, four years ago, I heard many causes as- signed for the prevailing discontent. My informants averred that, not less than the injustice of the landlords, had the arrogant and unsym- pathetic manners of many of them, and of many of their agents, served to alienate the people. In the development and satisfaction of the sympathies, let me repeat, lies the chief hope of establishing a true brotherhood among men. Seeking happiness as our aim, we declare knowledge, and obedi- ence to that knowledge, to be its means, and freedom its condition. The cultivation of the heart must receive our attention, not less than the improvement and equipment of the brain, if our lives are to be worthy, useful, and happy. A SCIENTIFIC YIEW OF THE COAL QUESTION. By G. GOEE. IT is well known that our stock of coal is not an infinite quantity, and can not last an infinite period of time. Different authorities, and those who have investigated the subject, including a royal com- mission, have assigned different lengths of time during which our supply is likely to last ; and, according to the most reliable authori- ties, it can not be much less than one hundred nor much more than two hundred and fifty years. Our abundant store of coal and its application to industrial pur- poses have been among the largest causes of our wealth and progress. The value of coal for those purposes depends essentially upon the fact 64 THE POPULAR SCIENCE MONTHLY. that it is combustible and evolves a large amount of beat in burning, and tbat this heat can be set free at any time and be readily converted into mechanical, chemical, electrical, and other forms of power. As an illustration of the great amount of energy contained in coal, it is well known to scientific men that each piece of it contains sufficient stored-up power to lift its own weight twenty-three hundred miles in height, or twenty-three hundred times its own weight a mile high. The only other common natural substances to be compared with it in this respect are wood and petroleum, and our stores of these are very small. It is by the expenditure of the energy contained in coal that comparatively valueless iron-ore is converted into valuable iron. It has not been by the mere existence of large quantities of coal in this country, nor entirely by the sale of coal to foreign nations, that so much of our wealth has been obtained, but largely by the circum- stance that we were the first nation to apply coal to industrial purposes on a large scale and in a great variety of ways. Other nations also possessing coal, perceiving the great success of this method, followed our example, have overtaken us, and have now rendered it increas- ingly difficult year by year for us to maintain our position as manu- facturers. As also large quantities of coal, petroleum, and inflammable gas are continually being discovered and utilized in other countries, and it is known that the United States of America alone contain nearly forty times as much coal as our entire stock, the time can not be very far distant when our chances of maintaining even our present position among nations by means of our coal will be considerably less than at present. It would be wise, therefore, boldly to face this serious pros- pect, and consider by what means our national prosperity can be main- tained as our coal diminishes in quantity and increases in price, especially as our population is continually increasing and has to pur- chase greater supplies of foreign food. There does exist another and inexhaustible source of wealth and progress, viz., new knowledge obtainable by means of scientific re- search. It is upon such knowledge, gained by experiments made to examine natural forces and substances, that we must sooner or later depend as a fundamental source of national prosperity. As fast as this knowledge is evolved by discoverers, it is applied in more imme- diately practical forms by numerous inventors, and then manufactur- ers and men of business use those practical realities in the production of wealth. This has been the order of events in the past and will be in the future ; this was the way in which we got wealth out of coal. Persons of narrow views on the subject will consider the above propo- sition vague and unpractical ; but this order of things is a great fact and unavoidable. We are the servants of Nature, and have no choice in the matter ; we might as well hope to live without food as expect to advance in civilization without the aid of new knowledge. A SCIENTIFIC VIEW OF THE COAL QUESTION. 65 The practical value of new scientific knowledge as a source of wealth and progress is incomparably greater than that of all the coal- deposits, petroleum-springs, and gold-fields of the earth. This great truth, though familiar to scientific investigators, is but little perceived or appreciated by our rulers or by the mass of their electors ; and the chief reason for this is the fact that they possess insufficient knowledge of science. Even governments can only appreciate that which they understand, and can only act as circumstances and public opinion allow them, and when fettered by an ignorant population are power- less to preserve a nation from decay. There can not be a more complete error than to suppose that new knowledge discovered by means of scientific research is not practical- Its immense practical value has been abundantly proved in a multi- tude of cases. It was largely by means of such knowledge respecting coal, its properties, constituents, and products gained by means of ex- periments, that coal was applied to so many uses. One of the most recent proofs of the practical value of such knowledge is the conver- sion of the heat of coal into electric current and light in the dynamo- electric machine and electric lamp ; the entire existence of these in- struments arose from new knowledge discovered in purely scientific researches by Davy and Faraday. It is not necessary to describe here the exact beginnings of gas-lighting, phosphorus-matches, photogra- phy, the voltaic battery, electro-plating, aniline dyes, telegraphy, the telephone, etc. These, and a multitude of other utilities in common use, had their earliest origin more or less completely, not in the labors of the inventor or of the more directly practical man, but in those of philosophical investigators whose experiments were made with the far more widely practical* object — the discovery of new scientific knowl- edge. It is not the mere possession of good things, but making the best and earliest use of them that most conduces to success. Our great stock of coal lay comparatively useless as a source of national wealth until philosophical investigators discovered its constituents and prop- erties, and inventors applied these to useful purposes. Other nations also possessed coal, and our greater success than theirs was largely and essentially due to the fact that we were the earliest in applying it to important and varied uses. We must not wait, therefore, for those nations to discover for us new knowledge respecting natural forces and substances, but discover it ourselves, in order that we may have the first chance of applying those forces and substances to practical uses, and of offering the useful products for sale or in exchange for food and other commodities. It is well known that a man who has no faith in medicine will not apply to a physician until death stares him in the face. Similarly the average politician and the ordinary elector, having but little knowl- edge of philosophical experiments or faith in them, will probably not VOL. XXTII. — 5 66 THE POPULAR SCIENCE MONTHLY. believe in their great practical value until national distress and panic legislation ensue. The love of money also, and the desire of acquir- ing it quickly without commensurate sacrifice, fostered by our having so easily obtained it by means of our coal and science, are so strong in this nation, that probably nothing but the actual loss of wealth in the form of diminished value of properties will induce capitalists and land- owners to perceive and examine the scientific basis of their incomes. When, however, the stern reality of gradually increasing scarcity of coal, and consequent inability to pay for our great supplies of foreign food by means of that coal, and of articles produced by its aid, comes upon us, perhaps the statesmen and wealthy classes of this country will see the indispensable necessity of new scientific knowledge, and be more ready to promote experimental research, with a conviction that its practical results are vast, though not always direct or immediate. — Nature. THE NERVOUS SYSTEM AND CONSCIOUSNESS. Bt w. e. benedict, PROFESSOR OF PSYCHOLOGY AND LOGIC IN THE UNIVERSITY OF CINCINNATI. II. MY former paper gave an outline account of the structure of the cerebro-spinal nervous system. The functions of this system were examined as far as to the cerebral hemispheres. It was said that we lacked evidence for the appearance of consciousness in connection with the activities of the spinal cord, the medulla oblongata, the pons Varolii, and the cerebellum. It was also affirmed that, if consciousness be associated with the activities of any organs below the cerebrum, this consciousness is of a general and vague kind, not the intelligence of clear perception. The present paper is to state the functions of the cerebral hemi- spheres, as far as these functions are thought to be established by re- cent experiment and pathology. "We shall need to refresh our minds by a general view of the cere- brum. Looking at this organ from the side, we readily distinguish its so-called lobes or divisions. These are made by the fissures or fur- rows which dip down from the surface, penetrating, more or less deeply, the entire mass. The prominent fissures are the fissure of Sylvius (S, Fig. 1) and the fissure of Rolando (R, Fig. 1). The fissure of Sylvius separates, in part, the temporo-sphenoidal lobe from the lobes above, and has two branches, a longer, horizontal branch (s), and a shorter, perpendicular branch (s'). If we push apart the brain-mass at the horizontal branch, we will see the nerve-matter called the Island of Reil. This is simply an additional fold of cell and fiber substance lying over the corpus THE NERVOUS SYSTEM AND CONSCIOUSNESS. 67 striatum. The fissure of Rolando separates the frontal lobe, F, from the rest of the brain. It begins at the great longitudinal division be- tween the hemispheres, and pursues an uninterrupted course to within a short distance of the horizontal branch of the Sylvian fissure. Back of the fissure of Rolando is the external perpendicular fissure (E) ; it AT MP F3- T.S. Fig. 1.— Fissures and Convolutions of the Human Brain. (Wundt.) Left side.

It is a prolongation, on the convex or lateral surface of the brain, of the deep fissure of the internal zone. This fissure marks the rear limit of the parietal lobe (P), which therefore lies between the fissure of Ro- lando and this furrow. Back of the parietal lobe is the occipital lobe (O). This region is less exactly defined ; an ideal prolongation of the external perpendicular fissure would determine its anterior and inferior limits. The temporo-sphenoidal lobe (T) has already been noticed as lying below the fissure of Sylvius. Among the various convolutions formed by these fissures there are three or four which must be named, because it is with them that the experiments in brain-functions are chiefly concerned. In the frontal lobe there are two of these convo- lutions (F 3), the third frontal convolution, or the convolution of Broca, and (A F) the fourth frontal convolution or ascending frontal fold. Broca's convolution has somewhat the shape of a horseshoe, and is formed around the ascending branch of the Sylvian fissure. The ascending frontal fold lies directly to the left of the fissure of Rolando, which it follows throughout. In the parietal lobe we notice (A P) the ascending parietal convolution immediately to the right of the fissure of Rolando, and (A G) the angular gyrus or pli courbe. This latter convolution is very complex in man. 68 THE POPULAR SCIENCE MONTHLY. It was believed for a long time that the cerebral hemispheres were insensible and inexcitable to direct stimulation. The Germans Fritsch and Hitzig discovered, however, that parts of the cerebrum would respond to a very gentle current of electricity. This beginning has been carefully followed up by Ferrier, Munk, Goltz, and many others, until we now have, amid much disagreement and uncertainty, some results that are interesting, to say the least. All experiments on the cerebrum are of two kinds (stimulation of the surface and destruction of the surface), and are necessarily made on the lower animals. Dupuy offered an objection to experiment by electrical stimulation, which, if well founded, would destroy the entire value of the undertaking. He claimed that the effects produced by electricity at the surface of the hemispheres were due wholly to con- duction of the current through the mass to the corpora striata below and so to the muscles. Dupuy proved that conduction did take place through the cell-mass of the hemispheres. He placed the leg of a frog in contact with the rear of a brain, and by application of electricity to the front of this brain produced strong movements in the limb. Ferrier's answers to Dupuy are a sufficient refutation of the objec- tion. If the effects observed under electrical stimulation are due to con- duction, we could not have (as is the case) strikingly different results from application of the electrodes to very closely adjacent areas. Further, when the striata themselves are stimulated, there is always a general contraction of muscles on the entire opposite side of the body. There is no limitation of the movements to special groups of muscles, as always happens when particular centers on the brain-surface are stimulated. Again, there are many portions of the brain which give no response to electrical stimulus. How can this be so if such move- ments as are produced result from conduction, especially since many of these silent regions of the brain are no more remote from the striata than the responsive ones ? Experiment and pathology, despite all the contradictions, seem to point to the existence of a motor zone on the surface of the hemi- spheres. This means that certain parts of the brain are directly con- cerned with the movements of particular muscles and groups of mus- cles ; also, that these parts can not be shown to be connected with sensations. The natural, primary occasions of their activity may be the states of consciousness which we call volitions ; they are not, so far as evidence goes, the states of consciousness we call sensations. It is of interest to observe that these motor regions are situated in the anterior portions of the hemispheres, and occupy here a relatively small space. They lie above the Sylvian fissure, and are mostly on the fourth frontal and ascending parietal convolutions. The experiments have been performed on a great variety of ani- mals, and repeated a large number of times. The monkey is, of course, THE NERVOUS SYSTEM AND CONSCIOUSNESS. 69 Fig. 2.— Lateral Aspect op Monkey's Brain, showing the relative positions of the so-called " Motor Centers " in the left Cerebral Hemisphere. (Ferrier.) the most interesting of these animals to us, from the striking resem- blance between his brain and the human brain. Hitzig's investigations, published in Berlin in 1874, give all the results gained up to that time by the stimulation experiments. Fer- rier's book, " The Functions of the Brain," London, 1876, better known to English readers, has spe- cial merit in two respects. It displays a very intelli- gent comprehension of the consequences of electrical stimulation, and seems to give a juster account of the motor regions in the mon- key's brain than was fur- nished by Hitzig. Figs. 2 and 3 will show the character and results of these experiments in suf- ficient detail. When center No. 1 is stimulated, the hind-limb on the opposite side of the body advances as in the act of walking ; when No. 5 is stimulated, the opposite arm and hand reach forward as if to touch something. These movements go together and are essentially the same. Centers 2 and 3 work to- gether ; when 2 is stimulated, there are combined movements of the opposite thigh, leg, and foot, and the foot is brought to the middle line of the body as in scratching that part, or in seizing something with the foot ; 3 gives movements of the tail. An interesting fact should be noted at this point. There is no center No. 2 in the brain of cat, dog, or jackal, while No. 3 is present in each. These animals do not grasp with the foot, and the monkey alone uses the rear foot for seizing. That No. 2 should be present, and of great size, in the monkey's brain, while absent else- where, is confirmatory of the ac- ^Z^*^n%£^j %£% curacy of the experiments. The ^^g^JK °K)ta ^ teft centers marked a, b, c, d, are on the ascending parietal convolution. "When stimulus is applied there, the fingers and wrist move with separate and combined movements 7o THE POPULAR SCIENCE MONTHLY. that end in closing the fist ; in connection with these centers we may note Nos. 4 and 5 ; they produce movements of the opposite arm and hand. It is plain that 4 and 5, and a, b, c, d, are closely related to one another. According to the theory of localization of functions, we should expect the centers, a, b, c, d, to be extensive in the monkey's brain, and to be wanting in the brains of lower animals. As matter of fact, they are absent in cat, dog, and jackal, except that a is found in the brain of the cat. This animal uses the front-paw for seizing and hold- ing. Upon stimulating center No. 6, the fore-arm bends, and the hand lifts to the mouth. This movement is constant with the monkey. There is no corresponding center in the brain of the dog or cat. The centers marked 7, 8, 9, 10, 11, are all concerned with movements of the mouth — such as elevating the angle of the mouth, depressing the lower lip, thrusting out and withdrawing the tongue. No. 12 lies quite to the front of the brain ; when it is stimulated, the eyes open widely, the pupils dilate, head and eyes turn toward the oppo- site side. These are the centers in the brain which, by some authorities, are thought to have a purely motor significance. The centers marked 13, 13', 14, and 15, give movements — the former of the eyes, the latter of the nostrils — but they are believed to be primarily connected with sensations. Aside from the centers enumerated, no other parts of the brain respond to stimulation. I have purposely stated the results of Ferrier's earlier experiments on the so-called motor zone. These experiments have been, in general, confirmed by other investigators. That is to say, the movements above described have been found by many to follow stimulation. It is, however, a part of the present confusion and contradiction which prevails respecting cerebral localization that the interpretation of these movements is disputed. Munk appears (" Transactions of the Physiological Society of Ber- lin," 1876-1878) with a series of experiments which, as he thinks, prove that the motor zone is primarily a zone of feeling. He there- fore divides this portion of the brain into spheres of feeling — one for the forward limbs, one for the head, one for the eyes, one for the ears, etc. Munk believes that the animal's movements are affected by destruction of these centers, because four distinct kinds of feeling are destroyed. For example, loss of the center concerned with movements of the fore-limb would, according to Munk, cause a loss — 1. Of the consciousness of pressure on the limb ; 2. Of the consciousness of the position of the limb ; 3. Of the consciousness of the motions belong- ing to the limb ; and, 4. Of the consciousness of touch in the limb. Whereas Ferrier and others find sensibility, both general and special, intact after destruction of these motor regions, Munk finds a loss of THE NERVOUS SYSTEM AND CONSCIOUSNESS. 71 sensibility so well defined and persistent as to justify the fourfold division above stated. We have now to inquire as to the testimony of pathology respect- ing these motor areas in the brain. Charcot and Pitres, in "Revue Mensuelle," November, 1878, and February, 1879, cite fifty-six cases of brain-dieases bearing on this subject. Twenty-one of these cases show lesions in the brain outside the motor zone, and unaccompanied by motor trouble. Charcot's deductions from these cases are that " there exist in the cortex of the cerebrum tracts which are independent of voluntary motion, and when lesions occur in these tracts there are no permanent affections of the motor functions." The remaining cases cited by Charcot show lesions in the motor zone, and are accompanied by varied degrees of paralysis in keeping with the situation and ex- tent of the lesion. Dr. Bechstrew, in the "Medicinische Wochen- schrift," St. Petersburg, details a number of cases which confirm the recent views on the motor functions of the areas about the middle convolutions. Other confirmatory cases have been cited by Burdon and Maragliano, by Dr. Henry Obersteiner, and many more. It is well known, however, that a number of opposing instances are on record — that is, of lesions in the so-called motor zone without paraly- sis, and of paralysis unaccompanied by lesions in these portions of the brain. There is a fundamental objection to this kind of evidence : it is selected evidence, chosen to make for or against a theory. What we really need is a collection of all cases of injuries to parts of the hemispheres, and a full statement of consequences without regard to the bearing of the example. This is the proper place to mention a brain disorder more or less commonly known under the name of aphasia. Aphasia is a disturb- ance of the power of speech. It appears in two distinct forms, viz., amnesic and ataxic aphasia. The person suffering from amnesic apha- sia forgets substantives and names, other parts of speech being prop- erly used ; or he forgets a language which he once knew, or he misap- plies terms, " using pamphlet for camphor, horse for man," etc. In ataxic aphasia the power of articulation is completely lost. The per- son understands fully the word to be used, and makes vigorous effort to use it, but is unable to do so. Sometimes articulation is half de- stroyed, so that the first part of the word can be spoken, but not the other. Sometimes automatic phrases can be uttered, such as yes and no, while it is perfectly clear that these exclamations do not satisfy the person. Another form of this general trouble is agraphia, or the inability to express ideas in writing ; this is frequently complete, and all attempts at writing end in a scrawl. It is noticeable that aphasia is sometimes, though seldom, unaccompanied by insanity. As early as 1861 Broca, in Paris, expressed the opinion that aphasia was connected with disease in the third frontal convolution. While a large number of cases have been cited for and against this conclusion, 72 THE POPULAR SCIENCE MONTHLY. many pathologists are disposed to regard it as substantially correct. It would seem just, then, to connect these central functions which are concerned in speech with the peculiarly developed region of the human brain that lies on the anterior and lower limit of the Sylvian fissure ; Wundt adds that perhaps the Island of Reil should be joined to this territory. We are now brought to consider directly the relation of portions of the brain to specific states of consciousness. I shall state the loca- tion of the senses as formerly made by Ferrier and by Munk, and will give a specimen experiment from each investigator. Sight is located by Ferrier in the angular gyrus (A, Fig. 1), by Munk in the occipital lobe (O, Fig. 1) ; hearing, by both, in the temporo-sphenoidal lobe (H, Fig. 1). Ferrier places smell and taste in the lower and inner aspect of the temporo-sphenoidal lobe (IT, Fig. 4). These centers are not distinguished by Munk. Ferrier names also a tactile center (H, Fig. 4). This he locates in what is known as the hippocampal region. If we separate the hemispheres from one another by cutting through the corpus callosum, we shall obtain a view of the median aspect of the hemispheres (see Fig. 4). Attention has been called to the fact that Munk disagrees with all Fig 4.— Median View op Eight Hemisphere of Human Bkain. (Ecker.) c c, Corpus callo- sum, connecting band between the hemispheres, longitudinally divided ; w, lower and inner portion of temporo-sphenoidal lobe, center of smell, according to Ferrier; H, hippocampal fold, touch. the authorities, except Schiff, in maintaining that a destruction of the motor centers destroys sensibility. Munk, therefore, does not indicate a special tactile center, but finds centers of feeling for head, neck, and back. Ferrier's experiment with regard to vision was as follows : He chloroformed the animal, a monkey, and destroyed the angular gyrus THE NERVOUS SYSTEM AND CONSCIOUSNESS. 73 on the left hemisphere. He bandaged the left eye, and allowed the animal to recover from the chloroform. " Upon recovery it began to grope about a little in loco, perfectly alert, but would not move from its position ; hearing and the other senses were not affected, for there was always a prompt reply to stimulation of these senses." The ani- mal remained in this position for an hour. The bandage was then removed from the left eye. "It instantly looked around, ran quickly to the cage and joined its companions. When brought to the light, as before, it flinched and turned away its head." Ferrier describes the change in the animal's manner, after removal of the bandage, as most complete and remarkable. On the following day the left eye was again bandaged, but "the animal gave plain signs of vision, it ran swiftly and accurately to the bars of the cage, thrust its head between them, and began to drink from a cup of water." In his next experi- ment Ferrier destroyed the angular gyrus on both hemispheres. He found great difficulty in forming a right test for vision, one which should discriminate between sight as a state of consciousness and sim- ple reflex reaction to visual stimulation. The animal sat perfectly still and would not move from its posi- tion. "The pupils contracted to light, and light flashed in the eyes caused the animal to wince." It was utterly unwilling to move from its place ; nothing else showed lack of vision. Ferrier's test was a cup of tea, which the animal liked very much. Ferrier placed the tea to the monkey's lips ; it began at once to drink eagerly. The cup was then removed, but barely removed, from contact with the lips. " The monkey seemed intensely anxious to drink, but could not find the tea, though both eyes were looking straight at it." As soon as contact was established, the monkey buried his head in the cup and followed it around the room, as the cup was slowly lowered. Munk's experiments on vision led him to different results. He re- moved the entire angular gyrus from the left hemisphere ; he then raised the lids of the left eye with his fingers and touched parts of the eye softly ; immediately there were blinking and vigorous movement of the head and muscles of the eye. The animal made every effort to draw back its head, and almost always accompanied these efforts by striking with the left front-limb. With the right eye, however, the case was entirely different. This eye could be pressed and pinched constantly, and the animal remained perfectly quiet. If the finger or hand was brought suddenly up close to the left eye there was blinking ; if to the right eye, no blinking at all resulted, unless the lids were actually touched. Munk removed the center, marked O, Fig. 1, from the occipital lobe in both hemispheres. He says : " In from three to five days after the opex*ation there was nothing abnormal in the hearing, smell, taste, movements, or sensations of the animal, only in the territory of sight was there any peculiar disturb- ance. The animal moved about the room or garden with perfect free- 74 THE POPULAR SCIENCE MONTHLY. dom, he did not strike against any object, and if things were put in his way he uniformly avoided them. There was, however, a striking difference. He regarded very coldly those men whom he used to greet most affectionately. He was indifferent to the dogs he always played with before. However hungry and thirsty he was, he did not go to the corner of the room where his food was, as formerly ; and, if food and water were placed directly in his path, he would go round and round them without noticing them at all. The sight of the whip, which used to drive him into the corner, did not now produce the slightest effect. He used to raise his paw when your hand was moved before his eyes ; now he will not lift it, however much the hand is moved." From these and similar facts, Munk draws a conclusion which, to say the least, seems a trifle broader than the premises. He says : " There can be no doubt about the meaning of these observations. By the extirpation of this portion of the brain, the dog has become soul- blind. He has lost the sight-perceptions which he once possessed ; his recollection-imag&s of things seen before are gone, so that he can not recognize what he sees — still he sees / sensations of sight come to his consciousness, so that he receives a knowledge of the existence, form, and position of external objects, but he does not know what these mean — this knowledge must be learned anew. The dog has been set back to his earliest years, to the time when he first opened his eyes ; he must learn to see." As removal of this part of the occipital lobe causes soul-blindness, so a removal of a portion of the temporo-sphenoidal lobe causes soul- deafness. Until lately the defenders of localization seemed to be justified in believing that something had been established as to a motor area of the brain ; they might well feel, also, that a beginning had been made toward connecting certain parts of the cortex with specific sensations and might hope that further experiment would remove, in considerable degree, the present disagreements. The doctrine of localization, both as a whole and in detail, has, however, received a severe blow at the hands of Professor Goltz, of Strasburg. In 1876 this distinguished experimenter began the publication of a series of papers in " Pfliiger's Archiv fur die gesammte Physiologic" In September, 1881, this series was finished and published by itself. Professor Goltz fearlessly declares that he has overthrown all the conclusions about division of the brain into motor and sensory areas, and brought back our knowl- edge of brain-function to the old view of Flourens, viz., that the cere- brum is one organ, having one function throughout. Professor Goltz's experiments were confined entirely to dogs, and their chief significance is due to the fact that he was able to keep the animal alive after re- moval of larger masses of the cerebrum than any other experimenter. These experiments seem to have been abundant and thorough. As a THE NERVOUS SYSTEM AND CONSCIOUSNESS. 75 result of them, Professor Goltz concludes that the degree of the dis- turbance of function from destruction of brain-substance depends upon the quantity removed, not upon the location of the lesion. He says, most positively, that " no extirpation of the motor centers, or of any other portion of gray matter, could cause permanent paralysis to any muscle in the body." His emphasis is upon the word permanent. Very many of the effects insisted on by advocates of localization did follow these brain-lesions, but the effects were not lasting, and they did not depend upon removal of specific portions of the substance. Blindness follows destruction of the angular gyrus, but it is temporary ; the animal will see again in time. Professor Goltz admits a compensation of brain- functions, so that remaining portions of the organ may take up the work of a part destroyed ; but this is not at all the compensation talked of by the supporters of localization. Their compensation re- quires that the additional work shall be done by the corresponding part in the other hemisphere. Professor Goltz destroys the angular gyrus on both sides and still his dog sees. Professor Goltz believes, however, that there are some permanent disturbances resulting from brain-lesions, such as " a certain dullness in the sensation of touch, a diminished power of vision, everything appearing cloudy to the eye, and some awkwardness in the movements." It will disturb the oppo- nents of vivisection to know that Professor Goltz sacrificed fifty-one dogs in attempting to determine the effects of lesion in both hemi- spheres. He found that what happened only to one side of the body, and that the opposite, if one hemisphere was dealt with, happened on both sides of the body if both cerebral masses were affected. In all these cases mental weakness increased toith the increasing quantity of matter removed. When considerable portions were taken away on both sides, the dog presented a demented appearance, very plain to be recognized. He could walk, run, see, hear, smell, and taste, but he was imbecile in all these activities. It was not to be supposed that so fierce an attack upon localization would go unchallenged. Professor Goltz certainly did not shrink from the demand to make good his assertions. He took up basket and dog and journeyed from Strasburg to London. Here, in 1881, he came be- fore the physiological section of the International Medical Congress, opened his basket, and, taking out the dog, placed him over against the almost equally celebrated monkey of Professor Ferrier. The dog walked, ran, saw, heard, tasted, and smelt ; this was as his master desired, yet he should not have behaved so, for he had lost almost all the centers for these respective functions. Large territories in both hemispheres were gone. He was clearly weak-minded, but, on the whole, he was not the kind of dog believed in by the advocates of localization. Professor Yeo even went so far as to say before the section, "I candidly admit that, should the entire of the so-called motor centers prove to be destroyed in this case, Professor Goltz 76 THE POPULAR SCIENCE MONTHLY. has succeeded in completely changing my views on cerebral locali- zation." After the dog there was the monkey. Professor Ferrier intro- duced him. He had lost the motor zone in the left hemisphere seven months previously. Of him Professor Ferrier said : " As to any inde- pendent volitional action of the right arm and leg we have not seen a single indication since the operation was made. The animal is, in every other respect, perfectly well, and as to its tactile sensibility there is not the slightest sign of impairment." It is pleasing to know that, as the dog had been faithful to his master, so the monkey was true to his friend ; he displayed the proper amount of paralysis on the oppo- site side of the body. In this connection Dr. Ireland's words are sug- gested. He says, "It is to be hoped, in the interest of the martyrs of cerebral physiology, that definite results will be attained as quickly and with as little suffering as possible." Whatever may or may not be accomplished in finding definite cen- ters of the brain for special movements and sensations, one thing stands fast — the cerebral hemispheres are the sole organs of the higher intel- lectual manifestations. From the time of Flourens, experiment has again and again shown that complete removal of the hemispheres is followed by stupor. All that resembles intellect disappears — sponta- neous volition is gone. The animal remains buried in the profoundest repose. He originates no action. A low form of sensation and a low form of volition may remain. The animal when pinched gives evi- dence of pain ; when set in motion, continues the motion till stopped by external hindrances. A frog deprived of the cerebrum and thrown into the water will swim until land is reached ; a pigeon thrown into the air will fly until stopped by an obstacle or by exhaustion. It is to be particularly observed that the motions of these animals are strict- ly normal, i. e., pure motions ; they are no longer connected with the higher power that once controlled them. They continue because they must continue. A writer in the "Journal of Anatomy," of Paris, 1870-'71, gives a clear account of this matter. He says : " As a summary, alike in the inferior and superior animals, the removal of the hemispheres does not cause to disappear any of the movements that previously existed, but these movements assume certain peculiar characters. They are regu- lar, for no psychical influence intervenes to modify them. They take place inevitably after excitation. The physiologist can, at will, in an animal deprived of the brain, determine such and such an act, limit it, arrest it. He can predict all the movements that will take place as certainly as a chemist knows in advance the reaction he will obtain from mixing certain bodies. Pathology confirms our conclusion respecting these higher func- tions of the cerebrum. Loss of cerebi-al substance, in man, is followed by a weakening of the intellectual powers. They make a very childish THE NERVOUS SYSTEM AND CONSCIOUSNESS. 77 mistake who attempt to deal with the physiological materialism of our day by citing the American crow-bar case, or any number of cases of brain-loss unaccompanied by marked intellectual enfeeblement. It is equally puerile to cite instances of small brains with great intellectual power. In the first place, these small brains may be of superior qual- ity, as small muscles often are ; or, in the second place, the boasted greatness of mind may be anything and everything but greatness of mind. Learning of a very extensive kind may coexist with small men- tal caliber. A monkey is shrewd and quick, and cunning and smart — a parrot is learned, up in a variety of languages, speaking, as many human parrots do, some French, some Italian, some Spanish : there is no great-mindedness here. Proof from size of the brain is, on the whole, reliable. There is, in general, a remarkable decrease in weight corresponding to the intel- lectual enfeeblement. Many idiots between the ages of sixteen, forty, and fifty years, have shown brains weighing 19f, 25f, and 22| ounces. There is on record the case of a deaf-mute idiot, forty-three years old, who showed an idiocy of the lowest kind, yet his brain weighed over forty-eight ounces. Such cases are not to overthrow an induction based upon a large majority of opposing instances. It remains for the succeeding paper to consider the question pro- pounded by the physiology of to-day, respecting the kind of relation which holds between the brain and consciousness. If we were to ac- cept the judgment of the younger leading physicians, we should be- lieve that modern Physiology had answered her own question. A distinguished physician of my city says, in his published " Lectures on Physiology " : " The so-called voluntary movements are only the final responses to impressions made upon the special senses at the time or in the past. The highest expressions of the intellect of man may be resolved into the more perfect transmutations of outside forces, by machinery made more perfect by original constitution or by labor." Without believing that such a correlation between brain and con- sciousness as is here asserted can be rationally accepted, there are, as I think, two general conclusions which may be drawn with cer- tainty : A constant relation obtains between nerve-matter and those mani- festations which are usually said to belong to the soul. This relation is so important, so constant, as to determine in large measure the intel- lectual and moral well-being of every individual. The origination of our states of consciousness, their character and conduct, are conditioned by physical processes antecedently occurring in the brain. 78 THE POPULAR SCIENCE MONTHLY. AECTIC EXPLORATION AND ITS OBJECT. By Dk. FKANZ BOAS. THE severe sufferings of the last Arctic expeditions, and the losses of life and property they occasioned, have depressed the public mind in regard to Arctic explorations. Great hopes have given way to the conviction of the impossibility of penetrating the ice-bound seas and accomplishing the task which formerly seemed easy. The effect of these failures is even more profound than we could anticipate ; for scientists themselves, and other men of intelligence and influence, now doubt if Arctic expeditions could be of any use either for mankind or for science. And the public mind to-day is so thoroughly imbued with these ideas, that it is necessary for every geographer to combat them with all his power. "We may be allowed to pass by the objections of men who measure the advantage of every study and of every enterprise by their influ- ence on commercial welfare. The scientist's objections are those we wish to refute. Many do not consider the discovery of new lands and new seas a task worthy a life's work, as they do not consider it a bene- fit for science — for their science, which is the deduction of laws from facts. They do not regard the composition of the wonderful picture of the world, as Humboldt tried to delineate in his " Cosmos " a science equal in its worth to the one which abstracts physical laws that govern matter in the worlds as well as in the atoms. However, cosmography, the study of the world and its development, is not at all inferior to physics, the study of its laws. Geography is one of the branches of science which represent the world as we see it to-day, and as it is developed into its present state. In its method and subject it is related to astronomy and history. Its domain is the study of the surface of our planet, as it has been developed by the physical action of land, atmosphere, and water, as well as by the relations between land and the organisms which live on it. Re- garding geography thus in its proper place in the system of sciences, we can not be allowed to consider any one of its objects as of no con- sequence and not worthy of being pursued with the same perseverance as those of physics, of astronomy, or natural history. In every branch of science the connection between the phenomena and processes, and the reasons for their distribution in space and time, can only be under- stood by the most thorough and detailed investigation. If it be granted that every fact added to our knowledge is of value for science, not by itself, but by connecting other facts already known, there is no reason for excluding geographical researches from this principle, or to consider discoveries of unknown regions as trifling. For the scientist it is not the benefit of commerce which makes ARCTIC EXPLORATION AND ITS OBJECT. 7g the importance of geographical exploration, it is the new material added to our stock of knowledge which enables us to make new comparisons and to reach a more thorough understanding of the world. If we intend to prove the necessity of new polar explorations, we do not need to dwell upon the many observations which are con- nected with Arctic research. If we should enter more closely into the meteorological and hydrographical or the magnetical problems which may be understood better by researches in regions near the pole ; if we should try to demonstrate the immense importance of those ques- tions for the meteorology of our own regions, and for the hydrography of the navigable ocean, or for the closer investigation of terrestrial magnetism which is necessary for the purposes of navigation, we should leave the stand-point we try to maintain here — the principle that we are not allowed to judge the value of scientific work by its immediate importance for science and life, but by its value for science itself. The effort has often been made to prove the necessity of continued polar exploration after the failure of so many attempts and the loss of so many brave lives, but the reasons brought forth were always those referring to the probable utility of new undertakings. It is not the proper way to defend a scientific work to point out the direct advantages which may be gained by it. Science itself has the right to ask any devotion of man for its purposes. A dangerous enterprise made in behalf of science does not need any proof of its usefulness, if it is possible to show that the results will indeed be a gain to the stock of our knowledge. If we agree that cosmography be equal in value to physics, or even if we only understand that progress in physics can not be made except by exploring the phenomena in the most minute and detailed way, we have to concede that new explorations in the Arctic regions are of value for science, and that, therefore, they are undoubtedly necessary and must be demanded. At the same time let us ask, What is the object of polar expeditions ? It is the thorough exploration of the Arctic region and of all its phe- nomena, a great task which will give scientists work for years to come. The problems will not be solved by pushing north and gaining the pole. There are many more objects of study left besides, and it is not necessary at all to work with all our might for the achievement of this single aim. The desires of humanity and the wants of science both direct us the same way. The phenomena of the highest latitudes are not of a kind which requires the promptest attention. Though the reaching of the pole may be desirable, it is not so urgent as to demand the sacrifice of noble lives in hazardous and adventurous enterprises which might be accomplished with relative safety at a later time. If the problems awaiting their solution in the Arctic were as pressing as those of ethnography, any attempt to reach the pole would be justi- 80 THE POPULAR SCIENCE MONTHLY. fied. Physical phenomena, however, are not so suhject to change as those of ethnography. Unknown tribes may be extinguished, or af- fected by the direct or indirect influence of civilization. The outlines of lands, tbe state of the weather and the sea, will not undergo altera- tions in the course of a few years. Therefore we can not see any reason why polar expeditions should be sent out only in order to reach the pole. The history of former expe- ditions proves that the most successful results were obtained by mak- ing ample use of the experience gained in former voyages, and that most of the failures were due to ignorance of previous observations, or to the careless neglect of previous experiences. If new expeditions should be organized — and they will be organized — we shall always plead for a slow but sure progress toward the pole. From the experi- ence gained hitherto, we are able to start at a point far north, and by studying the distribution of the land and the state of the ice yet farther north, we can conquer step by step the region hitherto un- known with comparative safety. The exploration of the pole is not a work for the bold and daring adventurer ; it is the task of the careful scientist, who knows thoroughly what science will profit by every mile gained, by the study of all the phenomena of regions often passed by ships or never visited by man. The results of a single expedition, however lucky it may be, will always be trifling as compared with the number of problems which have to be solved in the Arctic. It is quite possible that by favorable circumstances an expedition might succeed in getting far north, or discovering large areas of the unknown regions, as has happened in former years. However, the risk which the adventurers run can not be compared with the probable results. By deliberate perseverance, though the progress may be slower, the exploration of the Arctic will be accomplished in greater safety and with far greater results for science. We wish to establish here the principle that, in the present state of affairs, daring and adventurous explorations have to be excluded from a plan of Arctic researches which is founded on scientific princi- ples. This is not the place to determine the course which new expedi- tions have to take, as the discussion of this subject is not the affair of the public but of experts, who know thoroughly the phenomena of the Arctic seas and are conversant with the whole of Arctic literature. Whatever the new plans may be, the public and men of science must ask that the plan be not confined to a single expedition. The best results will be gained by considering the exploration of the polar regions as one continuous task, and fitting every new expedition into the far-seeing scheme of a thorough investigation of all the problems subject to Arctic researches. In this way we have the strong convic- tion that important results will be gained quicker than by spasmodic efforts now in Greenland, now in Behring Strait, now in Franz-Josef THE CHEMISTRY OF COOKERY. 81 Land. There can be no doubt that such a plan will be expensive, and not so apt to produce stirring results as any other ; however, it is not the purpose of the outgoing explorers to become sufferers and enduring heroes, but to bring home results which are important for their science. The meteorological stations which were established in 1882-'83 were the first step to the organization of an enterprise like that we demand, and their results will show the utility of well-founded plans. Hitherto I have only referred to the exploration of the unknown region never visited by men. There is more work left, however, which has to be included in a comprehensive plan of research. The southern parts of the Arctic regions — for example, the east shore of Greenland, many of the immense fjords of its west shore, Baffin Land, and the central parts of the north shore of America — are barely delineated. If we look at the charts, we might be induced to believe that most of these lands are sufficiently known, while, indeed, every new journey discloses the deficiency of our knowledge. These countries, which may be reached without serious difficulties, are the proper place for investigations of great importance, and the exploration of these parts of the Arctic is even more urgent than that of the far north, as the study of the numerous tribes which live on the shore of the Arctic Ocean has to be accomplished very soon ; else the rapid diminution of those peoples and the influence of European civilization will de- prive the ethnographer of anything to study but their moldering remains. It is easily understood why, after the northwest passage was found, no new researches in this part of the world were made. Many of the explorers, or those who planned the expeditions, were often more anx- ious to find sensational results than to further science. Polar explora- tion is now mostly considered merely the ambitious struggle of expe- ditions to get a few miles farther north than all the former explorers. We have tried to prove, in our remarks, that its aim is much nobler, and worth all the sacrifices which are brought to it. THE CHEMISTKY OF COOKEEY. By W. MATTIEU WILLIAMS. L. THE VEGETARIAN" QUESTION. IK my introductory paper I said, " The fact that we use the digestive and nutrient apparatus of sheep, oxen, etc., for the preparation of our food is merely a transitory barbarism, to be ultimately superseded when my present subject is sufficiently understood and applied to enable us to prepare the constituents of the vegetable kingdom to be vol. xxvii. — 6 82 THE POPULAR SCIENCE MONTHLY. as easily assimilated as the prepared grass which we call beef and mutton." This has brought me in communication with a very earnest body of men and women, who at considerable social inconvenience are ab- staining from flesh-food, and doing it purely on principle. Some peo- ple sneer at them, call them, " crotchety," " faddy," etc., but for my own part I have a great respect for crotchety people, having learned long ago that every first great step that has ever been taken in the path of human progress was denounced as a crotchet by those it was leaving behind. This respect is quite apart from the consideration of whether I agree or disagree with the crotchets themselves. I therefore willingly respond to the request that I should devote one short paper of this series to the subject. The fact that there are now in London nine exclusively vegetarian restaurants, and all of them flourishing, shows that it is one of wide interest. At the outset it is necessary to brush aside certain false issues that are commonly raised in discussing this subject. The question is not whether we are herbivorous or carnivorous animals. It is perfectly certain that we are neither. The carnivora feed on flesh alone, and eat that flesh raw. Nobody proposes that we should do this. The her- bivora eat raw grass. Nobody suggests that we should follow their example. It is perfectly clear that man can not be classed either with the carnivorous animals nor the herbivorous animals, nor with the grami- nivorous animals. His teeth are not constructed for munching and grinding raw grain, nor his digestive organs for assimilating such grain in this condition. He is not even to be classed with the omnivorous animals. He stands apart from all as The Cooking Animal. It is true that there was a time when our ancestors ate raw flesh, including that of each other. In the limestone caverns of this and other European countries we find human bones gnawed by human teeth, and split open by flint im- plements for the evident purpose of extracting the marrow, according to the domestic economy of the period. The shell-mounds that these prehistoric bipeds have left behind show that mussels, oysters, and other mollusca were also eaten raw, and they doubtless varied the menu with snails, slugs, and worms, as the remaining Australian savages still do. Besides these they probably included roots, succulent plants, nuts, and such fruit as then existed. There are many among us who are very proud of their ancient lineage, and who think it honorable to go back as far as possible, and to maintain the customs of their forefathers ; but they all seem to draw a line somewhere, none desiring to go as far back as to their in- terglacial trogloditic ancestors, and therefore I need not discuss the desirability of restoring their dietary. THE CHEMISTRY OF COOKERY. 83 All human beings became cooks as soon as they learned how to make a fire, and have all continued to be cooks ever since. We should, therefore, look at this vegetarian question from the point of view of prepared food, which excludes nearly all comparison with the food of the brute creation. I say "nearly all," because there is one case in which all the animals that approach the nearest to our- selves— the mammalia — are provided naturally with a specially pre- pared food, viz., the mother's milk. The composition of this prepara- tion appears to me to throw more light than anything else upon this vegetarian controversy, and yet it seems to have been entirely over- looked. The milk prepared for the young of the different animals in the laboratory or kitchen of Natui'e is surely adapted to their structure as regards natural food requirements. Without assuming that the human dietetic requirements are identical with either of the other mammals, we may learn something concerning our approximation to one class or another by comparing the composition of human milk with that of the animals in question. I find ready to hand in Dr. Miller's " Chemistry," Vol. III., a com- parative statement of the mean of several analyses of the milk of woman, cow, goat, ass, sheep, and bitch. The latter is a moderately carnivorous animal, nearly approaching the omnivorous character com- monly ascribed to man. The following is the statement : Bitch. Water Fat Sugar and soluble salts .Nitrogenous compounds and insolu- ble salts Woman. Cow. Goat. Ass. Sheep. 88-6 87-4 S2-0 90-5 S5-6 26 4-0 45 14 4-5 49 5-0 4-5 6-4 4-2 3-9 1 3-6 9-0 1-7 5-7 60-3 148 2-9 16-0 According to this it is quite evident that Nature regards our food requirements as approaching much nearer to the herbivora than to the carnivora, and has provided for us accordingly. If we are to begin the building-up of our bodies on a food more nearly resembling the herbivora than the carnivora, it is only reason- able to assume that we should continue on the same principle. The particulars of the difference are instructive. The food which Nature provides for the human infant differs from that provided for the young carnivorous animal, just in the same way as flesh-food dif- fers from the cultivated and cooked vegetables and fruit within easy reach of man. These contain less fat, less nitrogenous matter, more water, and more sugar (or starch, which becomes sugar during digestion) than animal food. Those who advocate the use of flesh-food usually do so on the ground that it it is more nutritious, contains more nitrogenous material and 84 THE POPULAR SCIENCE MONTHLY. more fat than vegetable food. So much the worse for the human being, says Nature, when she prepares food. But as a matter of practical fact there are no flesh-eaters among us, none who avail themselves of this higher proportion of albuminoids and fat. We all practically admit every day, in eating our ordinary English dinner, that this excess of nitrogenous matter and fat is bad ; we do so by mixing the meat with that particular vegetable which con- tains an excess of the carbo-hydrates (starch) with the smallest avail- able quantity of alhuminoids and fat. The slice of meat, diluted with the lump of potato, brings the whole down to about the average com- position of a fairly-arranged vegetarian repast. When I speak of a vegetarian repast, I do not mean mere cabbages and potatoes, but properly selected, well-cooked, nutritious vegetable food. As an ex- ample, I will take Count Rumford's No. 1 soup, already described, without the bread, and in like manner take beef and potatoes without bread. Taking original weights, and assuming that the lump of potato weighed the same as the slice of meat, we get the following composi- tion, according to the table given by Pavy, page 410 : Water. Albumen. Starch. Sugar. Fat. Salts. Lean beef 72-00 75-00 19-30 2-10 18-80 s-Va" 3-60 0-20 5-10 0-70 147-00 21-40 18-80 3-20 3-S0 5-80 73-50 10-70 9-40 1-60 1-90 2-90 Rumford's soup (without the bread afterward added) was com- posed of equal measures of peas and pearl-barley, or barley-meal, and nearly equal weights. Their percentage composition as stated in above- named table is as follows : Water. Albumen. Starch. Sugar. Fat. SaltB. 15-00 15-00 2300 6-30 55-40 69-40 2-00 4-90 2-10 2-40 2-50 2-00 30-00 29-30 13480 6-90 4-50 450 15-00 14-65 62-40 3-45 2-25 2-25 Here, then, in one hundred parts of the material of Rumford's half- penny dinner, as compared with the " mixed diet," we have forty per cent more of nitrogenous food, more than six and a half times as much carbo-hydrate in the form of starch, more than double the quantity of sugar, about seventeen per cent more of fat, and only a little less of salts (supplied by the salt which Rumford added). Thus the John Bull materials fall short of all the costly constituents, and only excel by their abundance of very cheap water. This analysis supplies the explanation of what has puzzled many THE CHEMISTRY OF COOKERY. 85 inquirers, and encouraged some sneerers at this work of the great scientific philanthropist, viz., that he found that less than five ounces of solids was sufficient for each man's dinner. He was supplying far more nutritious material than beef and potatoes, and therefore his five ounces was more satisfactory than a pound of beef and potatoes, three fourths of which is water, for which water John Bull pays a shilling or more per pound when he buys his prime steak. Rumford added the water at pump-cost, and, by long boiling, caused some of it to unite with the solid materials (by the hydration I have described), and then served the combination in the form of por- ridge, raising each portion to nineteen and three quarters ounces. I might multiply such examples to prove the fallacy of the prevail- ing notions concerning the nutritive value of the " mixed diet," a fal- lacy which is merely an inherited epidemic, a baseless physical super- stition. I will, however, just add one more example for comparison — viz., the Highlander's porridge. The following is the composition of oat- meal— also from Pavy's table : Sugar 5"40 Fat 5-60 Water 15"00 Albumen 12-60 Starch 58"40 Salts 3-00 Compare this with the beef and potatoes above, and it will be seen that it is superior hi every item excepting the water. This deficiency is readily supplied in the cookery. These figures explain a puzzle that may have suggested itself to some of my thoughtful readers — viz., the smallness of the quantity of dry oatmeal that is used in making a large portion of porridge. If we could, in like manner, see our portion of beef or mutton and potatoes reduced to dryness, the smallness of the quantity of actually solid food required for a meal would be similarly manifest. An alderman's ban- quet in this condition would barely fill a breakfast-cup. I can not at all agree with those of my vegetarian friends who de- nounce flesh-meat as a prolific source of disease, as inflaming the passions, and generally demoralizing. Neither am I at all disposed to make a religion of either eating or drinking, or abstaining. There are certain albuminoids, certain carbo-hydrates, certain hydrocarbons, and certain salts demanded for our sustenance. Excepting in fruit, these are not supplied by Nature in a fit condition for our use. They must be pre- pared. "Whether we do all the preparation in the kitchen by bringing the produce of the earth directly there, or whether, on account of our ignorance and incapacity as cooks, we pass our food through the stom- ach, intestines, blood-vessels, etc., of sheep and oxen, as a substitute for the first stages of scientific cookery, the result is about the same as regards the dietetic result. Flesh-feeding is a nasty practice, but I see no grounds for denouncing it as physiologically injurious. In my youthful days I was on friendly terms with a sheep that be- 86 THE POPULAR SCIENCE MONTHLY. longed to a butcher in Jermyn Street. This animal, for some reason, had been spared in its lambhood, and was reared as the butcher's pet. It was well known in St. James's by following the butcher's men through the streets like a dog. I have seen this sheep steal mutton- chops and devour them raw. It preferred beef or mutton to grass. It enjoyed robust health, and was by no means ferocious. It was merely a disgusting animal, with excessively perverted appe- tite ; a perversion that supplies very suggestive material for human meditation. My own experiments on myself, and the multitude of other experi- ments that I am daily witnessing among men of all occupations who have cast aside flesh-food after many years of mixed diet, prove in- contestably that flesh-food is quite unnecessary ; and also that men and women who emulate the aforesaid sheep to the mild extent of con- suming daily about two ounces of animal tissue combined with six ounces of water, and dilute this with such weak vegetable food as the potato, are not measurably altered thereby so far as physical health is concerned. On economical grounds, however, the difference is enormous. If all Englishmen were vegetarians, the whole aspect of the country would be changed. It would be a land of gardens and orchards, instead of gradually reverting to prairie grazing-ground as at present. The un- employed miserables of our great towns, the inhabitants of our union workhouses, and all our rogues and vagabonds, would find ample and suitable employment in agriculture. Every acre of land would require three or four times as much labor as at present, and feed five or six times as many people. No sentimental exaggeration is demanded for the recommendation of such a reform as this. I must apologize for this digression, as it has prevented me from closing this series with this paper, as I intended. In my next, which really will conclude, I shall describe some experiments I have recently made on the preparation of vegetable food. — Knowledge. PASTEUK'S KESEAKCHES IN GEKM-LIFE * Br Professor JOHN* TYNDALL. THE weightiest events of life sometimes turn upon small hinges ; and we now come to the incident which caused M. Pasteur to quit a line of research the abandonment of which he still regrets. A German manufacturer of chemicals had noticed that the impure com- * From the Introduction to " Louis Pasteur, his Life and Labors." By his Son-in-Law. New York : D. Applcton & Co , 1885. PASTEUR'S RESEARCHES IN GERM-LIFE. 87 mercial tartrate of lime, sullied with organic matters of various kinds, fermented on being dissolved in water and exposed to summer heat. Thus prompted, Pasteur prepared some pure, right-handed tartrate of ammonia, mixed with it albuminous matter, and found that the mixt- ure fermented. His solution, limpid at first, became turbid, and the turbidity he found to be due to the multiplication of a microscopic or- ganism, which found in the liquid its proper aliment. Pasteur recog- nized in this little organism a living ferment. This bold conclusion was doubtless strengthened, if not pi-ompted, by the previous dis- covery of the yeast-plant — the alcoholic ferment — by Cagniard-Latour and Schwann. Pasteur next permitted his little organism to take the carbon neces- sary for its growth from the pure paratartrate of ammonia. Owing to the opposition of its two classes of crystals, a solution of this salt, it will be remembered, does not turn the plane of polarized light either to the right or to the left. Soon after fermentation had set in, a rota- tion to the left was noticed, proving that the equilibrium previously existing between the two classes of crystals had ceased. The rotation reached a maximum, after which it was found that all the right-handed tartrate had disappeared from the liquid. The organism thus proved itself competent to select its own food. It found, as it were, one of the tartrates more digestible than the other, and appropriated it, to the neglect of the other. No difference of chemical constitution deter- mined its choice ; for the elements, and the proportions of the ele- ments, in the two tartrates were identical. But the peculiarity of structure which enabled the substance to rotate the plane of polariza- tion to the right also rendered it a fit aliment for the organism. This most remarkable experiment was successfully made with the seeds of our common mold {Penicillium glaucum). Here we find Pasteur unexpectedly landed amid the phenomena of fermentation. With true scientific instinct he closed with the concep- tion that ferments are, in all cases, living things, and that the sub- stances formerly regarded as ferments are in reality the food of the ferments. Touched by this wand, difficulties fell rapidly before him. He proved the ferment of lactic acid to be an organism of a certain kind. The ferment of butyric acid he proved to be an organism of a different kind. He was soon led to the fundamental conclusion that the capacity of an organism to act as a ferment depended on its power to live without air. The fermentation of beer was sufficient to suggest this idea. The yeast-plant, like many others, can live either with or without free air. It flourishes best in contact with free air, for it is then spared the labor of wresting from the malt the oxygen required for its sustenance. Supplied with free air, however," it practically ceases to be a ferment ; while in the brewing-vat, where the work of fermentation is active, the budding torula is completely cut off by the sides of the vessel, and by a deep layer of carbonic-acid 88 THE POPULAR SCIENCE MONTHLY. gas, from all contact with air. The butyric ferment not only lives without air, hut Pasteur showed that air is fatal to it. He finally di- vided microscopic organisms into two great classes, which he named respectively cerobies and ancerobies, the former requiring free oxygen to maintain life, the latter capable of living without free oxygen, but able to wrest this element from its combinations with other elements. This destruction of pre-existing compounds and formation of new ones, caused by the increase and multiplication of the organism, constitute the process of fermentation. Under this head are also rightly ranked the phenomena of putre- faction. As M. Radot well expresses it, the fermentation of sugar may be described as the putrefaction of sugar. In this particular field M. Pasteur, whose contributions to the subject are of the highest value, was preceded by Schwann, a man of great merit, of whom the world has heard too little.* Schwann placed decoctions of meat in flasks, sterilized the decoctions by boiling, and then supplied them with cal- cined air, the power of which to support life he showed to be unim- paired. Under these circumstances putrefaction never set in. Hence the conclusion of Schwann, that putrefaction was not due to the con- tact of air, as affirmed by Gay-Lussac, but to something suspended in the air which heat was able to destroy. This something consists of living organisms which nourish themselves at the expense of the or- ganic substance, and cause its putrefaction. The grasp of Pasteur on this class of subjects was embracing. He studied acetic fermentation, and found it to be the work of a minute fungus, the mycoderma aceti, which, requiring free oxygen for its nutrition, overspreads the surface of the fermenting liquid. By the alcoholic ferment the sugar of the grape-juice is transformed into car- bonic-acid gas and alcohol, the former exhaling, the latter remaining in the wine. By the mycoderma accti, the wine is, in its turn, convert- ed into vinegar. Of the experiments made in connection with this subject one deserves especial mention. It is that in which Pasteur suppressed all albuminous matters, and carried on the fermentation with purely crystallizable substances. He studied the deterioration of vinegar, revealed its cause, and the means of preventing it. He de- fined the part played by the little eel-like organisms which sometimes swarm in vinegar-casks, and ended by introducing important ameliora- tions and improvements in the manufacture of vinegar. The discussion with Liebig and other minor discussions of a similar nature, which M. Radot has somewhat strongly emphasized, I will not here dwell upon. It was impossible for an inquirer like Pasteur to evade the ques- tion, Whence come these minute organisms which are demonstrably capable of producing effects on which vast industries are built and on which whole populations depend for occupation and sustenance ? He thus found himself face to face with the question of spontaneous genera- * It was late in the day when the Royal Society made him a foreign member. PASTEUR'S RESEARCHES IN GERM-LIFE. 89 tion, to which the researches of Pouchet had just given fresh interest. Trained as Pasteur was in the experimental sciences, he had an im- mense advantage over Pouchet, whose culture was derived from the sciences of observation. One by one the statements and experiments of Pouchet were explained or overthrown, and the doctrine of spon- taneous generation remained discredited until it was revived with ardor, ability, and, for a time, with success, by Dr. Bastian. A remark of M. Radot's on page 103 needs some qualification. "The great interest of Pasteur's method consists," he says, "in its proving unanswerably that the origin of life in infusions which have been heated to the boiling-point is solely due to the solid particles suspended in the air." This means that living germs can not exist in the liquid when once raised to a temperature of 212° Fahr. No doubt a great number of organisms collapse at this temperature ; some, in- deed, as M. Pasteur has shown, are destroyed at a temperature 90° below the boiling-point. But this is by no means universally the case. The spores of the hay-bacillus, for example, have in numerous in- stances successfully resisted the boiling temperature for one, two, three, four hours ; while in one instance eight hours' continuous boiling failed to sterilize an infusion of desiccated hay. The knowledge of this fact caused me a little anxiety some years ago when a meeting was pro- jected between M. Pasteur and Dr. Bastian. For though, in regard to the main question, I knew that the upholder of spontaneous genera- tion could not win, on the particular issue touching the death tem- perature he might have come off victor. The manufacture and maladies of wine next occupied Pasteur's attention. He had, in fact, got the key to this whole series of prob- lems, and he knew how to use it. Each of the disorders of wine was traced to its specific organism, which, acting as a ferment, produced substances the reverse of agreeable to the palate. By the simplest of devices, Pasteur, at a stroke, abolished the causes of wine-disease. Fortunately the foreign organisms which, if unchecked, destroy the best red wines, are extremely sensitive to heat. A temperature of 50° C. (122° Fahr.) suffices to kill them. Bottled wines once raised to this temperature, for a single minute, are secured from subsequent de- terioration. The wines suffer in no degree from exposure to this tem- perature. The manner in which Pasteur proved this, by invoking the judgment of the wine-tasters of Paris, is as amusing as it is interest- ing. Moved by the entreaty of his master, the illustrious Dumas, Pasteur took up the investigation of the diseases of silk-worms at a time when the silk-husbandry of France was in a state of ruin. In doing so he did not, as might appear, entirely forsake his former line of research. Previous investigators had got so far as to discover vibratory corpus- cles in the blood of the diseased worms, and with such corpuscles Pasteur had already made himself intimately acquainted. He was, 9o THE POPULAR SCIENCE MONTHLY. therefore, to some extent at home in this new investigation. Tbe calamity was appalling, all the efforts made to stay the plague having proved futile. In June, 1865, Pasteur betook himself to the scene of tbe epidemic, and at once commenced his observations. On the even- ing of his arrival he had already discovered the corpuscles, and sbown them to others. Acquainted as he was with tbe work of living ferments, bis mind was prepared to see in tbe corpuscles the cause of the epidemic. He followed them through all the phases of the insect's life — through the eggs, through the worm, through the chrysalis, through the moth. He proved that tbe germ of the malady might be present in the eggs and escape detection. In the worm, also, it might elude microscopic examination. But in the moth it reached a develop- ment so distinct as to render its recognition immediate. From healthy moths, healthy eggs were sure to spring ; from healthy eggs, healthy worms ; from healthy worms, fine cocoons ; so that tbe problem of the restoration to France of its silk-husbandry reduced itself to the separation of the healthy from the unhealthy moths, the rejection of the latter, and the exclusive employment of the eggs of the former. M. Radot describes bow this is now done on the largest scale, with the most satisfactory results. The bearing of this investigation on the parasitic theory of com- municable diseases was thus illustrated : Worms were infected by per- mitting them to feed for a single meal on leaves over which corpuscu- lous matter had been spread ; they were infected by inoculation, and it was shown how they infected each other by tbe wounds and scratches of their own claws. By the association of healthy with diseased worms, the infection was communicated to the former. Infection at a distance was also produced by the wafting of the corpuscles through the air. The various modes in which communicable diseases are dif- fused among human populations were illustrated by Pasteur's treat- medt of tbe silk-worms. " It was no hypothetical infected medium — no problematical pythogenic gas — that killed the worms. It was a definite organism."* The disease thus far described is that called pebrine, which was the principal scourge at the time. Another for- midable malady was also prevalent, called flacherie, the cause of which and the mode of dealing with it were also pointed out by Pasteur. Overstrained by years of labor in this field, Pasteur was smitten with paralysis in October, 1868. But this calamity did not prevent him from making a journey to Alais in January, 1869, for the express purpose of combating the criticisms to which his labors bad been sub- jected. Pasteur is combustible, and contradiction readily stirs him into flame. No scientific man now living has fought so many battles as he. To enable him to render bis experiments decisive, tbe French emperor placed a villa at his disposal near Trieste, Avbere silk-worm * These -words were uttered at a time when the pythogenic theory was niorc in favor than it is now. PASTEUR'S RESEARCHES IN GERM-LIFE. 91 culture bad been carried on for some time at a loss. Tbe success bere is described as marvelous ; tbe sale of cocoons giving to tbe villa a net profit of twenty-six millions of francs.* From tbe imperial villa M. Pasteur addressed to me a letter, a portion of which I bave already publisbed. It may perbaps prove usefully suggestive to our Indian or colonial autborities if I reproduce it bere : " Permettez-moi de terminer ces quelques lignes que je dois dieter, vaincu que je suis par la maladie, en vous faisant observer que vous rendriez service aux colonies de la Grande-Bretagne en repandant la connaissance de ce livre, et des principes que j'etablis toucbant la mala- die des vers a soie. Beaucoup de ces colonies pourraient cultiver le mdrier avec succes, et, en jetant les yeux sur mon ouvrage, vous vous convaincrez aisement qu'il est facile aujourd'bui, nonseulement d'eloi- gner la maladie regnante, mais en outre de donner aux recoltes de la soie une prosperite qu'elles n'ont jamais eue." Tbe studies on wine prepare us for tbe " Studies on Beer," wbicb followed tbe investigation of silk-worm diseases. Tbe sourness, putrid- ity, and otber maladies of beer Pasteur traced to special " ferments of disease," of a totally different form, and tberef ore easily distinguisbed from tbe true torula or yeast-plant. Many mysteries of our breweries were cleared up by tbis inquiry. Witbout knowing tbe cause, tbe brewer not unfrequently incurred heavy losses through the use of bad yeast. Five minutes' examination with the microscope would have re- vealed to bim the cause of the badness, and prevented him from using tbe yeast. He would have seen the true torula overpowered by foreign intruders. The microscope is, I believe, now everywhere in use. At Burton-on-Trent its aid was very soon invoked. At the conclusion of bis studies on beer M. Pasteur came to London, where I had the pleas- ure of conversing with him. Crippled by paralysis, bowed down by tbe sufferings of France, and anxious about bis family at a troubled and an uncertain time, he appeared low in health and depressed in spirits. His robust appearance when he visited London, on the occa- sion of the Edinburgh Anniversary, was in marked and pleasing con- trast with my memory of bis aspect at tbe time to which I have re- ferred. While these researches were going on, the germ theory of infec- tious disease was noised abroad. The researches of Pasteur were fre- quently referred to as bearing upon the subject, though Pasteur him- self kept clear for a long time of this special field of inquiry. He was not a physician, and he did not feel called upon to trench upon the physician's domain. And now I would beg of him to correct me if, at this point of the introduction, I should be betrayed into any state- ment that is not strictly correct. In 1876 the eminent microscopist, Professor Cohn, of Breslau, was in London, and he then handed me a number of his "Beitr'age," con- * The work on " Diseases of Silk-worms " was dedicated to the Empress of the French. 9z THE POPULAR SCIENCE MONTHLY. taining a memoir by Dr. Koch on splenic fever (Milzbrand, Charbon, malignant pustule), which seemed to me to mark an epoch in the his- tory of this formidable disease. With admirable patience, skill, and penetration, Koch followed up the life-history of bacillus anthracis, the contasrium of this fever. At the time here referred to he was a young physician, holding a small appointment in the neighborhood of Breslau, and it was easy to predict, as I predicted at the time, that he would soon find himself in a higher position. When I next heard of him he was head of the Imperial Sanitary Institute of Berlin. Koch's recent history is pretty well known in England, while his appreciation by the German Government is shown by the rewards and honors lately conferred upon him. Koch was not the discoverer of the parasite of splenic fever. Da- vaine and Rayer, in 1850, had observed the little microscopic rods in the blood of animals which had died of splenic fever. But they were quite unconscious of the significance of their observation, and for thirteen years, as M. Radot informs us, strangely let the matter drop. In 1863 Davaine's attention was again directed to the subject by the researches of Pasteur, and he then pronounced the parasite to be the cause of the fever. He was opposed by some of his fellow-country- men ; long discussions followed, and a second period of thirteen years, ending with the publication of Koch's paper, elapsed, before M. Pas- teur took up the question. I always, indeed, assumed that from the paper of the learned German came the impulse toward a line of in- quiry in which M. Pasteur has achieved such splendid results. Things presenting themselves thus to my mind, M. Radot will, I trust, forgive me if say that it was with very great regret that I perused the dis- paraging references to Dr. Koch which occur in the chapter on splenic fever. After Koch's investigation, no doubt could be entertained of the parasitic origin of this disease. It completely cleared up the perplexity previously existing as to the two forms — the one fugitive, the other permanent — in which the contagion presented itself. I may say that it was on the conversion of the permanent hardy form into the fugitive and sensitive one, in the case of bacillus subtilis and other organisms, that the method of sterilizing by " discontinuous heating " introduced by me in February, 1877, was founded. The difference between an organism and its spores, in point of durability, had not escaped the penetration of Pasteur. This difference Koch showed to be of para- mount inportance in splenic fever. He, moreover, proved that while mice and Guinea-pigs were infallibly killed by the parasite, birds were able to defy it. And here we come upon what may be called a band-specimen of the genius of Pasteur, which strikingly illustrates its quality. Why should birds enjoy the immunity established by the experiments of Koch ? Here is the answer. The temperature which prohibits the PASTEUR'S RESEARCHES IN GERM-LIFE. 93 multiplication of bacillus anthracis in infusions is 44° C. (111° Fahr.). The temperature of the blood of birds is from 41° to 42° Fahr. It is therefore close to the prohibitory temperature. But then the blood- globules of a living fowl are sure to offer a certain resistance to any attempt to deprive them of their oxygen — a resistance not experienced in an infusion. May not this resistance, added to the high tempera- ture of the fowl, suffice to place it beyond the power of the parasite ? Experiment alone could answer this question, and Pasteur made the experiment. By placing its feet in cold water he lowered the tempera- ture of a fowl to 37° or 38° Fahr. He inoculated the fowl, thus chilled, with the splenic-fever parasite, and in twenty-four hours it was dead. The argument was clinched by inoculating a chilled fowl, permitting the fever to come to a head, and then removing the fowl, wrapped in cotton-wool, to a chamber with a temperature of 35° Fahr. The strength of the patient returned as the career of the parasite was brought to an end, and in a few hours health was restored. The sharpness of the reasoning here is only equaled by the conclusiveness of the experiment, which is full of suggestiveness as regards the treat ment of fevers in man. Pasteur had little difficulty in establishing the parasitic origin of fowl-cholera ; indeed, the parasite had been observed by others before him. But, by his successive cultivations, he rendered the solution sure. His next step will remain forever memorable in the history of medicine. I allude to what he calls " virus attenuation." And here it may be well to throw out a few remarks in advance. When a tree, or a bundle of wheat or barley straw, is burned, a certain amount of mineral matter re- mains in the ashes — extremely small in comparison with the bulk of the tree or of the straw, but absolutely essential to its growth. In a soil lacking, or exhausted of, the necessary mineral constituents, the tree can not live, the crop can not grow. Now, contagia are living things, which demand certain elements of life just as inexorably as trees, or wheat, or barley ; and it is not difficult to see that a crop of a given parasite may so far use up a constituent existing in small quantities in the body, but essential to the growth of the parasite, as to render the body unfit for the production of a second crop. The soil is exhausted, and, until the lost constituent is restored, the body is protected from any further attack of the same disorder. Such an explanation of non- recurrent diseases naturally presents itself to a thorough believer in the germ theory, and such was the solution which, in reply to a ques- tion, I ventured to offer nearly fifteen years ago to an eminent London physician. To exhaust a soil, however, a parasite less vigorous and destructive than the really virulent one may suffice ; and, if, after hav- ing by means of a feebler organism exhausted the soil, without fatal result, the most highly virulent parasite be introduced into the system, it will prove powerless. This, in the language of the germ theory, is the whole secret of vaccination. 94 THE POPULAR SCIENCE MONTHLY. The general problem, of which Jenner's discovery was a particular case, has been grasped by Pasteur, in a manner, and with results, which five short years ago were simply unimaginable. How much " accident " had to do with shaping the course of his inquiries I know not. A mind like his resembles a photographic plate, which is ready to accept and develop luminous impressions, sought and unsought. In the chapter on fowl-cholera is described how Pasteur first obtained his attenuated virus. By successive cultivations of the parasite he showed that, after it had been a hundred times reproduced, it continued to be as virulent as at first. One necessary condition was, however, to be observed. It was essential that the cultures should rapidly succeed each other — that the organism, before its transference to a fresh cultivating liquid, should not be left long in contact with air. When exposed to air for a considerable time the virus becomes so enfeebled that when fowls are inoculated with it, though they sicken for a time, they do not die. But this "attenuated" virus, which M. Radot justly calls "benign," constitutes a sure protection against the virulent virus. It so exhausts the soil that the really fatal contagium fails to find there the elements necessary to its reproduction and multiplication. Pasteur affirms that it is the oxygen of the air which, by length- ened contact, weakens the virus and converts it into a true vaccine. He has also weakened it by transmission through various animals. It was this form of attenuation that was brought into play in the case of Jenner. The secret of attenuation had thus become an open one to Pasteur. He laid hold of the murderous virus of splenic fever, and succeeded in rendering it, not only harmless to life, but a sure protection against the virus in its most concentrated form. No man, in my opinion, can work at these subjects so rapidly as Pasteur without falling into errors of detail. But this may occur while his main position remains impreg- nable. Such a result, for example, as that obtained in presence of so many witnesses at Melun must surely remain an ever-memorable con- quest of science. Having prepared his attenuated virus, and proved, by laboratory experiments, its efficacy as a protective vaccine, Pasteur accepted an invitation, from the President of the Society of Agricult- ure at Melun, to make a public experiment on what might be called an agricultural scale. This act of Pasteur's is, perhaps, the boldest thing recorded in this book. It naturally caused anxiety among his colleagues of the Academy, who feared that he had been rash in clos- ing with the proposal of the president. But the experiment was made. A flock of sheep was divided into two groups, the members of one group being all vaccinated with the attenuated virus, while those of the other group were left unvacci- nated. A number of cows were also subjected to a precisely similar treatment. Fourteen days afterward all the sheep and all the cows, vaccinated and unvaccinated, were inoculated with a very virulent PASTEUR'S RESEARCHES IN GERM-LIFE. 95 virus ; and three days subsequently more than two hundred persons assembled to witness the result. The " shout of admiration," men- tioned by M. Radot, was a natural outburst under the circumstances. Of twenty-five sheep which had not been protected by vaccination, twenty-one were already dead, and the remaining ones were dying. The twenty-five vaccinated sheep, on the contrary, were "in full health and gayety." In the unvaccinated cows intense fever was pro- duced, while the prostration was so great that they were unable to eat. Tumors were also formed at the points of inoculation. In the vacci- nated cows no tumors were formed ; they exhibited no fever, nor even an elevation of temperature, while their power of feeding was unim- paired. No wonder that "breeders of cattle overwhelmed Pasteur with applications for vaccine." At the end of 1881 close upon thirty- four thousand animals had been vaccinated, while the number rose in 1883 to nearly five hundred thousand. M. Pasteur is now exactly sixty-two years of age ; but his energy is unabated. At the end of this volume we are informed that he has already taken up and examined with success, as far as his experiments have reached, the terrible and mysterious disease of rabies or hydro- phobia. Those who hold all communicable diseases to be of parasitic origin, include, of course, rabies among the number of those produced and propagated by a living contagium. From his first contact with the disease Pasteur showed his accustomed penetration. If we see a man mad, we at once refer his madness to the state of his brain. It is somewhat singular that in the face of this fact the virus of a mad dog should be referred to the animal's saliva. The saliva is, no doubt, in- fected, but Pasteur soon proved the real seat and empire of the dis- order to be the nervous system. The parasite of rabies had not been securely isolated when M. Ra- dot finished his task. But last May, at the instance of M. Pasteur, a commission was appointed, by the Minister of Public Instruction in France, to examine and report upon the results which he had up to that time obtained. A preliminaiy report, issued to appease public impatience, reached me before I quitted Switzerland this year. It in- spires the sure and certain hope that, as regards the attenuation of the rabic virus, and the rendering of an animal, by inoculation, proof against attack, the success of M. Pasteur is assured. The commis- sion, though hitherto extremely active, is far from the end of its labors ; but the results obtained so far may be thus summed up : Of six dogs unprotected by vaccination, three succumbed to the bites of a dog in a furious state of madness. Of eight unvaccinated dogs, six succumbed to the intravenous in- oculation of rabic matter. Of five unvaccinated dogs, all succumbed to inoculation, by tre- panning, of the brain. Finally, of three-and-twenty vaccinated dogs, not one was attacked 96 THE POPULAR SCIENCE MONTHLY. with the disease subsequent to inoculation with the most potent virus. Surely results such as those recorded in this book are calculated, not only to arouse public interest, but public hope and wonder. Never before, during the long period of its history, did a day like the present dawn upon the science and art of medicine. Indeed, previous to the discoveries of recent times, medicine was not a science, but a collection of empirical rules dependent for their interpretation and application upon the sagacity of the physician. How does England stand in rela- tion to the great work now going on around her ? She is, and must be, behindhand. Scientific chauvinism is not beautiful in my eyes. Still, one can hardly see, without deprecation and protest, the English investigator handicapped in so great a race by short-sighted and mis- chievous legislation. A great scientific, theory has never been accepted without opposi- tion. The theory of gravitation, the theory of undulation, the theory of evolution, the dynamical theory of heat — all had to push their way through conflict to victory. And so it has been with the germ theory of communicable diseases. Some outlying members of the medical profession dispute it still. I am told they even dispute the communi- cability of cholera. Such must always be the course of things, as long as men are endowed with different degrees of insight. Where the mind of genius discerns the distant truth, which it pursues, the mind not so gifted often discerns nothing but the extravagance, which it avoids. Names, not yet forgotten, could be given to illustrate these two classes of minds. As representative of the first class, I would name a man whom I have often named before, who, basing himself in great part on the researches of Pasteur, fought, in England, the battle of the germ theory with persistent valor, but whose labors broke him down before he saw the triumph which he foresaw completed. Many of my medical friends will understand that I allude here to the late Dr. William Budd, of Bristol. The task expected of me is now accomplished, and the reader is here presented with a record in which the verities of science are en- dowed with the interest of romance. -♦♦♦- TEAINING IN ETHICAL SCIENCE. By H. II. CUETIS. THE importance of education in the duties of life is recognized in a greater or less degree by all. People differ widely as to abso- lute standards of right and wrong, and as to the foundation or source of such standards, but all concede by daily acts, as well as by avowed opinions, the necessity of some kind of moral training. Every parent TRAINING IN ETHICAL SCIENCE. 97 who restrains his child from the commission of a wrongful act, or ap- proves its conduct when praiseworthy, does so in recognition of the importance of moral education. Every individual who uses his influ- ence to keep others from evil associations, or who commends a noble or kindly act, thus manifests his appreciation of the necessity of moral or ethical culture. However undefined may be the limits, however imperfectly understood may be the sources of the laws of duty, it is continually forced upon the attention of every thoughtful person that a proper observance of these laws is of vast importance to mankind. The happiness of man — the great legitimate end of human effort — depends so largely upon the recognition and adoption of high standards of duty, that nothing can exceed in importance the cultivation of the science of duty and the spirit of right action. The human race is still far from a condition of ideal perfection ; man has not as yet reached his highest estate. In the words of Ten- nyson : " A monstrous eft was of old the Lord and Master of Earth ; For him did his high sun shine, and his river billowing ran, And he felt himself in his force to be Nature's crowning race. As nine months go to the shaping an infant ripe for its birth, So many a million of ages have gone to the making of man ; He now is first, but is he the last? is he not too base? '' The world is full of want and misery ; the strong trample upon the rights of the weak, the cunning take advantage of the unwary, the impulsive and the irresolute are lured on to lives of vice and crime. From every quarter there arise appeals for help, for strength to over- come temptation, for power to resist oppression, for succor in distress. Beyond all these things, as we ascend in the scale of ethical develop- ment, there exists a demand for that recognition of the rights of others, that spirit of fellowship and true manhood which shall abridge and overcome the passion of grasping selfishness. How prevalent is the desire for that ostentatious splendor and luxurious ease which too often represent the fruits of many a hard and narrow life of penury and ill-requited toil ! We live in an age of observation, of investigation, of a study of Nature's laws and methods. Nor is the advance of the physical sci- ences more marked than that of the useful arts. Do not the problems of life also demand attention ? Is a knowledge of the laws of the physical universe so all-important that no time shall be spared, no thought devoted to acquiring further knowledge of the laws of duty ? Every thoughtful observer must admit that the great governing factor in the problem of the advancement of human happiness is the conduct of man toioard his felloto-man. Immeasurable in importance is the fostering of a spirit of true devotion to duty. There is no loftier am- bition, no nobler work, no higher ideal of life, than the promotion of the virtue, goodness, and happiness of mankind. VOL. XXVII. — 7 98 THE POPULAR SCIENCE MONTHLY. What are the means by which these ends shall be accomplished ? Shall we rely solely upon our supposed consciousness of what is right and what is wrong, and let moral teaching consist simply of appeals for obedience to the dictates of conscience ? That which is termed conscience is, in a large degree at least, a matter of inherited tenden- cies, education, and intellectual development, and varies with the in- dividual, his surroundings, and the age in which he lives. That which seems right to the mind of one man often seems wrong when presented to the intelligent judgment of other men. The con- science of the average member of a civilized community differs widely from the conscience of the average member of a savage tribe. To the American Indian, revenge is a virtue ; to the Quaker, revenge is a crime. To Gautama, to Jesus of Nazareth, and to their ascetic dis- ciples, the total rejection of personal interest or advancement — absolute unselfishness and self-abnegation, unlimited benevolence, and an entire absence of the desire or habit of self-protection — were the greatest virtues and most obligatory duties. On the other hand, the constitutions of all civilized governments, whether written or unwritten, the principles of the civil as well as those of the common law, and the teachings of wise men of ancient and of modern times, recognize as a duty the protection of individual or selfish interests. They recognize as just and necessary the restraint and pun- ishment of wrong-doers, and the protection of the rights and interests of the individual in person and property. Educated to look upon these and kindred principles as embodying correct rules of conduct, we view with approval the resistance of oppression and injustice, and even the spirit which resents and punishes insult. There can be no doubt that these are conflicting views of duty, but both extremes have been honestly maintained, and still are in some degree. It hardly admits of a doubt that men of pure motives and good intentions have committed acts of cruelty and inhumanity in the belief that they were simply discharging duties — perchance religious duties. All these things point to the fallibility of human judgment regard- ing standards of duty, and the imperfect development of ideas of right and wrong. They furnish no excuse, however, for drifting through life without an attempt to investigate or discover the principles of the science of duty, or for neglecting to govern our actions by those prin- ciples, so far as we may be able to recognize them. With the waning and crumbling of a faith in any books or records as containing absolute or inspired standards of duty, the study of the science and data of ethics should, it would seem, become one of greater interest and attention than ever before. Whether we regard the ability to distinguish between right and wrong conduct as in a great degree inherent in the human mind, or as having arisen in the course of the evolution of the race, as a sense TRAINING IN ETHICAL SCIENCE. 99 of that which is conducive to the happiness of man, it is certainly a faculty or sense which is largely developed by educational training and example. Without this, it surely can not be relied upon as an unerring guide in all the problems of life. Man does not possess a power to distinguish between right and wrong action which rises superior to the need of cultivation. For such culture teachers are required, and the great necessity of united action is apparent. If associated action in the shape of schools of moral or ethical training, and agencies for charitable work — the fruit of such training — are de- manded, we are confronted with the question of what their nature should be, and how far the want is already supplied. If the means now provided for these purposes are as good as any that can be devised, and if they are suited to the needs and uses of all, it were idle to supply other agencies. Foremost, perhaps, among the agencies now existing, are the churches. According to the theories adopted and taught by the various religious organizations which are collectively known as Chris- tian, the cultivation of ethical truths, or, in other words, the recogni- tion and adoption of high standards of duty, is regarded as but a part of a religious system founded upon the revealed will of a Divine Being. To those who accept so-called revelation as infallible truth, the rules of conduct or systems of ethics recognized in their Scriptures furnish, in theory, and so far as they can be harmonized, final and absolute standards of human duty. To them, theoretically at least, right or wrong action is such simply by reason of its adherence to or departure from certain standards of duty recognized in their sacred writings. To the individual who looks upon the sacred books of Jew and Christian, of Mohammedan and Buddhist, as alike the works of men — men of varying degrees of mental and moral development — the idea of accepting their conclusions as Jinal upon the great problems of the duty of man seems narrow and illogical. To him the absolute accept- ance of these standards as final, however high he may concede some of them to be, is to place a limit upon moral development and to deny that " The thoughts of men are widened with the process of the suns." But it does not follow, even from the point of view of the agnostic, that there is nothing of value in the ethical teachings of the orthodox Christian churches. Most if not all religions have recognized, and in some sense demanded, the adoption of certain exalted standards of duty, and in this particular the Christian religion stands deservedly high among the great religions of the world. Charity, kindness, and love, are not less beautiful because recognized as such by the churches. A true statement of the duty of man to his fellow-man does not become false because attributed to a Divine Being, or declared to be inspired. It does not become false even when the observance of the duty is loo THE POPULAR SCIENCE MONTHLY. sought to be enforced by an appeal to selfish interests — by the promise of reward or the threat of punishment in a life of which we know not. Nor is the value of the moral teaching of the churches to be ignored merely because they insist that it is the duty of all to accept and adopt their theological teachings — their conception of the infinite and un- known, with its attendant dogmas and " cramping bounds of creed." The crude and sometimes wholly indefensible theories of right and wrong which are recognized and treated as of divine authority in por- tions of the Scriptures do not furnish a sufficient reason for an unquali- fied condemnation of the ethical teachings of the churches. It is in general only in some strained theory — rarely in a practical application to the duties of life — that the most extreme and ultra standards of duty recognized in the writings which are collectively known as the Bible are inculcated, or even defended, inside the churches. Even those men whose mistaken zeal and religious bias lead them to attempt a defense of all the varying and inconsistent standards of duty recognized or pro- mulgated by the many authors of the writings which make up our Bible, do so rather in theory than in fact. In their daily life, or prac- tical advice to others, they adopt neither the standard of implacable and indiscriminating revenge and cruelty on the one hand, nor that of absolute self-abasement and meek submission to insult and injury on the other, which are alternately represented as attributes of the Divine character by the respective authors of these so-called sacred writings. Without stopping here to discuss the objectionable featm-es of a system of ethical training or education which has its nominal founda- tion in the supposed fiat of a Divine Intelligence, and which in theory necessarily precludes the possibility of the development of higher standards, it may be conceded that such education in morals is better than none. The value of such education is not wholly counterbalanced by the evil of its constant appeal to the selfish interests by promises of personal reward or threats of punishment, rather than to the nobler sen- timents of the mind. Conceding the moral education of the churches to be imperfect in theory, in the manner in which it is imparted, and the means by which it is sought to be enforced, it nevertheless contains elements of good to those who can-receive it. The believer of course finds in the ethical teachings of his church a deeper and fuller moral education than they impart to others. He can at least give due weight to their real merits, and they are to him authoritative in a greater or less degree — the degree being dependent upon his faith in their divine origin. From long association of ideas and the influence of early education, the attendant theological teach- ings do not suggest to him that sense of incongruity and inconsistency which they present to others. But how far is the moral education furnished by the Church suited to the needs of those who are compelled to reject its theological dog- mas concerning the unknown, and to regard its standards of duty as TRAINING IN ETHICAL SCIENCE. 101 those of fallible men only ? Does it furnish to the earnest and fearless seeker for moral truth an undeviating path to the object of his search ? Is he not constantly invited to depart from his course on journeys through the pathless wastes of theological speculation, where each man thinks his diverging creed marks the true highway to heaven ? There are various reasons why the earnest seeker for truth who is without religious belief can not feel content with the Church as a teacher of moral duty. The energy, the time, the money which should be devoted to building up character, to a recognition of the duties of man to his fellow-man, to the relief of the afflicted, to an intelligent dealing with the great problems of this life — he sees devoted largely to building up, jjromulgating, or seeking excuse for dogmas and the- ories from which his intelligence revolts. With want and suffering appealing for relief, with ignorance demanding enlightenment, with a thousand duties at our doors which scarcely receive a passing notice, we are asked to follow these blind teachers of the blind away from the things of this world, and to enjoy with them their irrational conception of what is to us the unknown — perhaps the unknowable. Of what value is a sermon on the duty and efficacy of prayer, to one who looks upon the question of the existence of a Divine Being as an insoluble problem ? Of what use or benefit to him is a dis- course on the nature of the Trinity, or the theory of the atonement ? The rationalist is compelled to look upon the books which make up the Bible as simply the work of fallible men, of varying degrees of in- telligence, and representing the thought of widely differing periods of human development. To him, what is there of interest in attempts to reconcile their contradictions and inconsistencies — attempts to estab- lish the untenable theory that they embody and set forth the plan and design of an all-wise Author of the universe ? If the rationalist would support and uphold the ethical school of the Church, he is in a measure also supporting and upholding theologi- cal ideas which are to him in the last degree unreasonable and improb- able. His money pays misguided men for teaching the ignorant of earth that the all-foreseeing and merciful Author of all things would doom his creatures to suffer untold agony throughout eternity for the sins and mistakes of a short life, or for using the reason with which he has endowed them ! Where one dollar goes to relieve want, or build up character, two go to build up church or creed. The relief of the widow and the fatherless is thought a matter of less importance than acquainting the heathen with the theological dogmas of the Chris- tian Church. Of course the church-going and church-supporting rationalist must expect to be continually reminded of the culpability of his unbelief, which, so far as he can judge, arises simply from an exercise of his rea- soning faculties, and not from any wrongful intention. He becomes wearied and disheartened by the want of consideration shown for the 102 THE POPULAR SCIENCE MONTHLY. duties of this life, and the undue prominence given to a supposed preparation for an alleged future life, of which he has no evidence and can form no conception. But though the Church fails to furnish adequate ethical training to those who can not accept its theological teachings, some kind of moral education is necessary if we would have true moral develop- ment. While much can be done in the home circle in teaching the rudiments of the science of duty — the beauty of love and charity and other attributes of noble character — this is not alone sufficient to meet the demand which should exist for true ethical culture. Teachers are needed. The complicated interests which surround most of the great social and moral problems demand the most careful and patient study, and only he who has brought to these tasks the forces of a well-trained mind can suggest the true means of relief from con- ditions which all may recognize as deplorable. The value of associa- tion with a broad and generous mind — a mind filled with high and pure conceptions of duty — a mind which ever presents and holds be- fore us high and noble ideals, can not well be overestimated. The time may come when the Church will so far outgrow the myths, the dogmas, and the beliefs with which it now straggles that there will be room within it for all who would earnestly unite in efforts to better the condition of man, and to diffuse a knowledge of those principles which lie at the foundation of human happiness. There is, indeed, a progress of thought in the Church far broader and deeper than any actual modifications of written creeds would indicate. We will not pause to inquire as to what class of thinkers is chiefly en- titled to the credit for this progress. This rapid development in the direction of individual freedom of thought may give us at length a church — by whatever name it may be designated — where the only creed held binding will be the creed of love, the only devotion essen- tial to true fellowship a devotion to truth and duty. Meanwhile, though there are signs of progress, and noble excep- tions in the few societies for ethical culture now existing, and in sim- ilar organizations, it is evident that the demand for ethical progress outside the Church has not as yet culminated in any general con- structive effort either in the direction of improving the condition of the weak, the needy, and the suffering, or in the cultivation of the sci- ence of duty. It is in one sense an unfortunate circumstance that most rational- ists are persons of very independent habits of thought. Their work in the past has been necessarily and perhaps almost too largely one of iconoclasm. The exposure of shams, the demolition of creed and dogma, the unveiling of myth and traditional faith based upon founda- tions which have slowly crumbled away in the light of increasing in- telligence, have thus far largely occupied the attention of the ration- alist. The men who have done this work are not of a nature which A VERY OLD MASTER. 103 bids them cling together for mutual support and sympathy, and as a whole they have hardly the characteristics which would qualify them for united constructive effort. Nevertheless, association is needed. A comparison of views, each individual reaping the benefit of the thought of his co-workers, is of the highest value. Without associated action but little enthusiasm can be expected, and enthusiasm is all- important in carrying forward any good work. The employment of earnest and competent teachers and leaders in thought is practicable only through united action. For charitable work — the relief of want, the alleviation of suffering, the furnishing of employment, the assist- ance which helps others to help themselves — associated and united effort is well-nigh indispensable. And in earnest exertions to improve the condition and add to the happiness of our fellows, may be found the best and highest ethical culture, giving to those who engage in the work a new conception as it were of the higher duties and nobler life of man. -«-*»- A VEEY OLD MASTER. THE work of art which lies before me is old, unquestionably old ; a good deal older, in fact, than Archbishop Usher (who invented all out of his own archiepiscopal head the date commonly assigned for the creation of the world) would by any means have been ready to admit. It is a bas-relief by an old master, considerably more antique in origin than the most archaic gem or intaglio in the Museo Borbonico at Naples, the mildly decorous Louvre in Paris, or the eminently re- spectable British Museum, which is the glory of our own smoky London in the spectacled eyes of German professors, all put together. When Assyrian sculptors carved in fresh white alabaster the flowing curls of Sennacherib's hair, just like a modern coachman's wig, this work of primaeval art was already hoary with the rime of ages. When Mem- phian artists were busy in the morning twilight of time with the towering coiffure of Rameses or Sesostris, this far more ancient relic of plastic handicraft was lying, already fossil and forgotten, beneath the concreted floor of a cave in the Dordogne. If we were to divide the period for which we possess authentic records of man's abode upon this oblate spheroid into ten epochs — an epoch being a good, high- sounding word which doesn't commit one to any definite chronology in particular — then it is probable that all known art, from the Egyp- tian onward, would fall into the tenth of the epochs thus loosely de- markated, while my old French bas-relief would fall into the first. To put the date quite succinctly, I should say it was most likely about 244,000 years before the creation of Adam according to Usher. The work of the old master is lightly incised on reindeer-horn, and represents two horses, of a very early and heavy type, following io4 THE POPULAR SCIENCE MONTHLY. one another, with heads stretched forward, as if sniffing the air sus- piciously in search of enemies. The horses would certainly excite un- favorable comment at Newmarket. Their " points " are undoubtedly coarse and clumsy : their heads are big, thick, stupid, and ungainly ; their manes are bushy and ill-defined ; their legs are distinctly feeble and spindle-shaped ; their tails more closely resemble the tail of the domestic pig than that of the noble animal beloved with a love passing the love of women by the English aristocracy. Nevertheless, there is little (if any) reason to doubt that my very old master did, on the whole, accurately represent the ancestral steed of his own exceedingly remote period. There were once horses even as is the horse of the prehistoric Dordonian artist. Such clumsy, big-headed brutes, dun in hue and striped down the back like modern donkeys, did actually once roam over the low plains where Paris now stands, and browse off lush grass and tall water-plants around the quays of Bordeaux and Lyons. Not only do the bones of the contemporary horses, dug up in caves, prove this, but quite recently the Russian traveler Prjevalsky (whose name is so much easier to spell than to pronounce) has discovered a similar living horse, which drags on an obscure existence somewhere in the high table-lands of Central Asia. Prjevalsky's horse (you see, as I have only to write the word, without uttering it, I don't mind how often or how intrepidly I use it) is so singularly like the clumsy brutes that sat, or rather stood, for their portraits to my old master, that we can't do better than begin by describing him in propria persona. The horse family of the present day is divided, like most other families, into two factions, which may be described for variety's sake as those of the true horses and the donkeys, these latter including also the zebras, quaggas, and various other unfamiliar creatures whose names, in very choice Latin, are only known to the more diligent visi- tors at the Sunday Zoo. Now everybody must have noticed that the chief broad distinction between these two great groups consists in the feathering of the tail. The domestic donkey, with his near congeners, the zebra and co., have smooth, short-haired tails, ending in a single bunch or fly-whisk of long hairs collected together in a tufted bundle at the extreme tip. The horse, on the other hand, besides having horny patches or callosities on both fore and hind legs, while the donkeys have them on the fore-legs only, has a hairy tail, in which the long hairs are almost equally distributed from top to bottom, thus giving it its peculiarly bushy and brushy appearance. But Prjevalsky's horse, as one would naturally expect from an early intermediate form, stands half-way in this respect between the two groups, and acts the thank- less part of a family mediator ; for it has most of its long tail-hairs collected in a final flourish, like the donkey, but several of them spring from the middle distance, as in the genuine Arab, though never from the very top, thus showing an approach to the true horsey habit with- out actually attaining that final pinnacle of equine glory. So far as one A VERY OLD MASTER. 105 can make out from the somewhat rude handicraft of my prehistoric Phidias, the horse of the quaternary epoch had much the same caudal peculiarity ; his tail was bushy, but only in the lower half. He was still in the intermediate stage between horse and donkey, a natural mule still struggling up aspiringly toward perfect horschood. In all other matters the two creatures — the cave-man's horse and Prjevalsky's — closely agree. Both display large heads, thick necks, coarse manes, and a general disregard of " points " which would strike disgust and dismay into the stout breasts of Messrs. Tattersall. In fact, over a T. Y. C. it may be confidently asserted, in the pure Saxon of the sport- ing papers, that Prjevalsky's and the cave-man's lot wouldn't be in it. Nevertheless, a candid critic would be forced to admit that, in spite of clumsiness, they both mean staying. So much for the two sitters ; now let us turn to the artist who sketched them. Who was he, and when did he live ? Well, his name, like that of many other old masters, is quite unknown to us ; but what does that matter, so long as his work itself lives and survives ? Like the Comtists he has managed to obtain objective immortality. The work, after all, is for the most part all we ever have to go upon. " I have my own theory about the authorship of the Iliad and Odyssey," said Lewis Carroll ( of "Alice in Wonderland ") once in Christ Church common-room ; " it is that they weren't really written by Homer, but by another person of the same name." There you have the Iliad in a nutshell as regards the authenticity of great works. All we know about the supposed Homer (if anything) is that he was the reputed author of the two unapproachable Greek epics ; and all we know di- rectly about my old master, viewed personally, is that he once carved with a rude flint flake on a fragment of reindeer-horn these two clumsy prehistoric horses. Yet by putting two and two together we can make, not four, as might be naturally expected, but a fairly connected history of the old master himself and what Mr. Herbert Spencer would no doubt playfully term his "environment." The work of art was dug up from under the firm concreted floor of a cave in the Dordogne. That cave was once inhabited by the name- less artist himself, his wife, and family. It had been previously ten- anted by various other early families, as well as by bears who seem to lived there in the intervals between the different human occupiers. Probably the bears ejected the men, and the men in turn ejected the bears, by the summary process of eating one another up. In any case the freehold of the cave was at last settled upon our early French artist. But the date of his occupancy is by no means recent ; for since he lived there the long cold spell known as the Great Ice Age, or Glacial Epoch, has swept over the whole of Northern Europe, and swept before it the shivering descendants of my poor prehistoric old master. Now, how long ago was the Great Ice Age ? As a rule, if you ask a geologist for a definite date, you will find him very chary of 106 THE POPULAR SCIENCE MONTHLY. giving you a distinct answer. He knows that the chalk is older than the London clay, and the oolite than the chalk, and the red marl than the oolite ; and he knows also that each of them took a very long time indeed to lay down, but exactly how long he has no notion. If you say to him, " Is it a million years since the chalk was deposited ? " he will answer, like the old lady of Prague, whose ideas were excessively vague, " Perhaps." If you suggest five millions, he will answer oracu- larly once more, " Perhaps " ; and if, you go on to twenty millions, "Perhaps," with a broad smile, is still the only confession of faith that torture will wring out of him. But in the matter of the Glacial Epoch, a comparatively late and almost historical event, geologists have broken thi-ough their usual reserve on this chronological question, and condescended to give us a numerical determination. And here is how Dr. Croll gets at it. Every now and again, geological evidence goes to show us, a long cold spell occurs in the northern or southern hemisphere. During these long cold spells the ice-cap at the poles increases largely, till it spreads over a great part of what are now the temperate regions of the globe, and makes ice a mere drug in the market as far south as Covent Garden or the Halles at Paris. During the greatest extension of this ice-sheet in the last glacial ej)och, in fact, all England except a small southwestern corner (about Torquay and Bournemouth) was completely covered by one enormous mass of glaciers, as is still the case with almost the whole of Greenland. The ice-sheet, grinding slowly over the hills and rocks, smoothed, and polished, and striated their surfaces in many places till they resembled the roches moutonnees similarly ground down in our own day by the moving ice-rivers of Chamouni and Grindelwald. Now, since these great glaciations have occurred at various intervals in the world's past history, they must de- pend upon some frequently recurring cause. Such a cause, therefore, Dr. Croll began ingeniously to hunt about for. He found it at last in the eccentricity of the earth's orbit. This world of ours, though usually steady enough in its movements, is at times decidedly eccenti'ic. Not that I mean to impute to our old and exceedingly respectable planet any occasional aberrations of intellect, or still less of morals (such as might be expected from Mars and Venus) ; the. word is here to be accepted strictly in its scientific or Pickwickian sense as implying merely an irregularity of movement, a slight wob- bling out of the established path, a deviation from exact circularity. Owing to a combination of astronomical revolutions, the precession of the equinoxes and the motion of the aphelion (I am not going to explain them here ; the names alone will be quite sufficient for most people ; they will take the rest on trust) — owing to the combination of these profoundly interesting causes, I say, there occur certain periods in the world's life when for a very long time together (10,500 years, to be quite precise) the northern hemisphere is warmer than the south- A VERY OLD MASTER. 107 era, or vice versa. Now, Dr. Croll has calculated that about 250,000 years ago this eccentricity of the eai'th's orbit was at its highest, so that a cycle of recurring cold and warm epochs in either hemisphere alternately then set in ; and such cold spells it was that produced the Great Ice Age in Northern Europe. They went on till about 80,000 years ago, when they stopped short for the present, leaving the climate of Britain and the neighboring continent with its existing inconvenient Laodicean temperature. And, as there are good reasons for believing that my old master and his contemporaries lived just before the great- est cold of the Glacial Epoch, and that his immediate descendants, with the animals on which they feasted, were driven out of Europe, or out of existence, by the slow approach of the enormous ice-sheet, we may, I think, fairly conclude that his date was somewhere about b. c. 248,000. In any case we must at least admit, with Mr. Andrew Lang, the laureate of the twenty-five thousandth century, that " He lived in the long, loog agoes ; 'Twas the manner of primitive man." The old master, then, carved his bas-relief in pre-glacial Europe, just at the moment before the temporary extinction of his race in France by the coming on of the Great Ice Age. We can infer this fact from the character of the fauna by which he was surrounded, a fauna in which species of cold and warm climates are at times quite capriciously intermingled. We get the reindeer and the mammoth side by side with the hippopotamus and the hyena ; we find the chilly cave-bear and the Norway lemming, the musk-sheep and the Arctic fox in the same deposits with the lion and the lynx, the leopard and the rhinoceros. The fact is, as Mr. Alfred Russel Wallace has pointed out, we live to-day in a zoologically impoverished world, from which all the largest, fiercest, and most remarkable animals have lately been weeded out. And it was in all probability the coming on of the Ice Age that did the weeding. Our Zoo can boast no mammoth and no mastodon. The saber-toothed lion has gone the way of all flesh ; the deinotherium and the colossal ruminants of the Pliocene Age no longer browse beside the banks of Seine. But our old master saw the last of some at least among those gigantic quadrupeds ; it was his hand, or that of one among his fellows, that scratched the famous mam- moth etching on the ivory of La Madelaine, and carved the figure of the extinct cave-bear on the reindeer-horn ornaments of Laugerie Basse. Probably, therefore, he lived in the period immediately preceding the Great Ice Age, or else perhaps in one of the warm interglacial spells with which the long secular winter of the northern hemisphere was then from time to time agreeably diversified. And what did the old master himself look like ? Well, painters have always been fond of reproducing their own lineaments. Have we not the familiar young Raphael painted by himself, and the Rem- brandt, and the Titian, and the Rubens, and a hundred other self- 108 THE POPULAR SCIENCE MONTHLY. drawn portraits, all flattering and all famous ? Even so primitive man has drawn himself many times over, not indeed on this particular piece of reindeer-horn, but on several other media to be seen elsewhere, in the original or in good copies. One of the best portraits is that dis- covered in the old cave at Laugerie Basse by M. Elie Massenat, where a very early pre-glacial man is represented in the act of hunting an aurochs, at which he is casting a flint-tipped javelin. In this as in all other pictures of the same epoch I regret to say that the ancient hunter is represented in the costume of Adam before the fall. Our old mas- ter's studies, in fact, are all in the nude. Primitive man was evidently unacquainted as yet with the use of clothing, though primitive woman, while still unclad, had already learned how to heighten her natural charms by the simple addition of a necklace and bracelets. Indeed, though dresses were still wholly unknown, rouge was even then ex- tremely fashionable among French ladies, and lumps of the ruddle with wrhich primitive woman made herself beautiful forever are now to be discovered in the corner of the cave where she had her little pre- historic boudoir. To return to our hunter, however, who for aught we know to the contrary may be our old master himself in person, he is a rather crouching and semi-erect savage, with an arched back, re- calling somewhat that of the gorilla, a round head, long neck, pointed beard, and weak, shambling, ill-developed legs. I fear we must admit that pre-glacial man cut, on the whole, a very sorry and awkward figure. Was he black ? That we don't certainly know ; but all analogy would lead one to answer positively, Yes. White men seem, on the whole, to be a very recent and novel improvement on the original evo- lutionary pattern. At an}' rate he was distinctly hairy, like the Ainos, or aborigines of Japan, in our own day, of whom Miss Isabella Bird has drawn so startling and sensational a picture. Several of the pre-glacial sketches show us lank and gawky savages with the body covered with long scratches, answering exactly to the scratches which represent the hanging hair of the mammoth, and suggesting that man then still retained his old original hairy covering. The few skulls and other fragments of skeletons now preserved to us also indicate that our old master and his contemporaries much resembled in shape and build the Australian black fellows, though their foreheads were lower and more receding, while their front teeth still projected in huge fangs, faintly recalling the immense canines of the male gorilla. Quite apart from any theoretical considerations as to our probable descent (or ascent) from Mr. Darwin's hypothetical " hairy arboreal quadru- manous ancestor," whose existence may or may not be really true, there can be no doubt that the actual historical remains set before us pre-glacial man as evidently approaching in several important respects the higher monkeys. It is interesting to note, too, that while the Men of the Time still A VERY OLD MASTER. 109 retained (to be frankly evolutionary) many traces of the old monkey- like progenitor, the horses which our old master has so cleverly deline- ated for us on his scrap of horn similarly retained many traces of the earlier united horse-and-donkey ancestor. Professor Huxley has ad- mirably reconstructed for us the pedigree of the horse, beginning with a little creature from the Eocene beds of New Mexico, with five toes to each hind-foot, and ending with the modern horse, whose hoof is now practically reduced to a single and solid-nailed toe. Intermediate stages show us an Upper Eocene animal as big as a fox, with four toes on his front feet and three behind ; a Miocene kind as big as a sheep, with only three toes on the front-foot, the two outer of which are smaller than the big middle one ; and, finally, a Pliocene form, as big as a donkey, with one stout middle toe, the real hoof, flanked by two smaller ones, too short by far to reach the ground. In our own horse these lateral toes have become reduced to what are known by veter- inaries as splint-bones, combined with the canon in a single solidly mortised piece. But in the pre-Glacial horses the splint-bones still generally remained quite distinct, thus pointing back to the still earlier period when they existed as two separate and independent side-toes in the ancestral quadruped. In a few cave specimens, however, the splints are found united with the canons in a single piece, while con- versely horses are sometimes, though very rarely, born at the present day with three-toed feet exactly resembling those of their half-forgot- ten ancestor, the Pliocene hipparion. The reason why we know so much about the horses of the cave period is, I am bound to admit, simply and solely because the man of the period ate them. Hippophagy has always been popular in France ; it was practiced by pre-Glacial man in the caves of Perigord, and re- vived with immense enthusiasm by the gourmets of the Boulevards after the siege of Paris and the hunger of the Commune. The cave- men hunted and killed the wild horse of their own times, and one of the best of their remaining works of art represents a naked hunter attacking two horses, while a huge snake winds itself unperceived be- hind close to his heel. In this rough prehistoric sketch one seems to catch some faint antique foreshadowing of the rude humor of the " Petit Journal pour Rire." Some archaeologists even believe that the horse was domesticated by the cave-men as a source of food, and argue that the familiarity with its form shown in the drawings could only have been acquired by people who knew the animal in its domesticated state ; they declare that the cave-man was obviously horsey. But all the indications seem to me to show that tame animals were quite un- known in the age of the cave-men. The mammoth certainly was never domesticated ; yet there is a famous sketch of the huge beast upon a piece of his own ivory, discovered in the cave of La Madelaine by Messrs. Lartet and Christy, and engraved a hundred times in works on archaeology, which forms one of the finest existing relics of pre- no THE POPULAR SCIENCE MONTHLY. Glacial art. In another sketch, less well known, but not unworthy of admiration, the early artist has given us with a few rapid hut admira- ble strokes his own reminiscence of the effect produced upon him by the sudden onslaught of the hairy brute, tusks erect and mouth wide open, a perfect glimpse of elephantine fury. It forms a capital exam- ple of early impressionism, respectfully recommended to the favorable attention of Mr. J. M. Whistler. The reindeer, however, formed the favorite food and favorite model of the pre-Glacial artists. Perhaps it was a better sitter than the mammoth ; certainly it is much more frequently represented on these early prehistoric bas-reliefs. The high-water mark of palaeolithic art is undoubtedly to be found in the reindeer of the cave of Thayngen, in Switzerland, a capital and spirited representation of a buck grazing, in which the perspective of the two horns is better managed than a Chinese artist would manage it at the present day. Another drawing of two reindeer fighting, scratched on a fragment of schistose rock and unearthed in one of the caves of Perigord, though far inferior to the Swiss specimen in spirit and execution, is yet not without real merit. The perspective, however, displays one marked infantile trait, for the head and legs of one deer are seen distinctly through the body of another. Cave-bears, fish, musk-sheep, foxes, and many other extinct or existing animals, are also found among the archaic sculptures. Probably all these creatures were used as food ; and it is even doubt- ful whether the artistic troglodytes were not also confirmed cannibals. To quote Mr. Andrew Lang once more on primitive man, "he lived in a cave by the seas ; he lived itpon oysters and foes." The oysters are quite undoubted, and the foes may be inferred with considerable cer- tainty. I have spoken of our old master more than once under this rather question-begging style and title of primitive man. In reality, how- ever, the very facts which I have here been detailing serve themselves to show how extremely far our hero was from being truly primitive? You can't speak of a distinguished artist, who draws the portraits of extinct animals with grace and accuracy, as in any proper sense pri- mordial. Grant that our good troglodytes were indeed light-hearted cannibals ; nevertheless, they could design far better than the modern Esquimaux or Polynesians, and carve far better than the civilized being who is now calmly discoursing about their personal peculiarities in his own study. Between the cave-men of the pre-Glacial age and the hy- pothetical hairy quadrumanous ancestor aforesaid there must have intervened innumerable generations of gradually improving intermedi- ate forms. The old master, when he first makes his bow to us, naked and not ashamed, in his Swiss or French grotto, flint scalpel in hand and necklet of bear's teeth dropping loosely on his hairy bosom, is nevertheless in all essentials a completely evolved human being, with a whole past of slowly acquired culture lying dimly and mysteriously A VERY OLD MASTER. in behind him. Already he has invented the bow with its flint-tipped arrow, the neatly chipped javelin-head, the bone harpoon, the barbed fish-hook, the axe, the lance, the dagger, and the needle. Already he had learned how to decorate his implements with artistic skill, and to carve the handles of his knives with the figures of animals. I have no doubt that he even knew how to brew and to distill ; and he was probably acquainted with the noble art of cookery as applied to the persons of his human fellow-creatures. Such a personage can not rea- sonably be called primitive ; cannibalism, as somebody has rightly remarked, is the first step on the road to civilization. No, if we want to get at genuine, unadulterated primitive man, we must go much further back in time than the mere trifle of 250,000 years, with which Dr. Croll and the cosmic astronomers so generously provide us, for pre-Glacial humanity. We must turn away to the im- measurably earlier fire-split flints which the Abbe Bourgeois — un- daunted mortal ! — ventured to discover among the Miocene strata of the calcaire de Beauce. Those flints, if of human origin at all, were fashioned by some naked and still more hairy creature, who might fairly claim to be considered as genuinely primitive. So rude are they that, though evidently artificial, one distinguished archaeologist will not admit they can be in any way human ; he will have it that they were really the handiwork of the great European anthropoid ape of that early period. This, however, is nothing more than very delicate hair-splitting ; for what does it matter whether you call the animal that fashioned these exceedingly rough and fire-marked implements a man-like ape or an ape-like human being ? The fact remains quite un- altered, whichever name you choose to give to it. When you have got to a monkey who can light a fire and proceed to manufacture him- self a convenient implement, you may be sure that man, noble man, with all his glorious and admirable faculties — cannibal or otherwise — is lurking somewhere very close, just round the corner. The more we examine the work of our old master, in fact, the more does the con- viction force itself upon us, that he was very far indeed from being primitive — that we must push back the early history of our race not for 250,000 winters alone, but perhaps for two or three million years, into the dim past of Tertiary ages. But if pre-Glacial man is thus separated from the origin of the race by a very long interval indeed, it is none the less true that he is sepa- rated from our own time by the intervention of a vast blank space, the space occupied by the coming on and passing away of the Glacial Epoch. A great gap cuts him off from what we may consider as the relatively modern age of the mound-builders, whose grassy barrows still cap the summits of our southern chalk-downs. When the great ice-sheet drove away palaeolithic man — the man of the caves and the unwrought flint axes — from Northern Europe, he was still nothing more than a naked savage in the hunting stage, divinely gifted for art 112 THE POPULAR SCIENCE MONTHLY. indeed, but armed only with roughly-chipped stone implements, and wholly ignorant of taming animals, or of the very rudiments of agri- culture. He knew nothing of the use of metals — aiirum irrepertum spernere fortior — and he had not even learned how to grind and polish his rude stone tomahawks to a finished edge. He couldn't make him- self a bowl of sun-baked pottery, and if he had discovered the almost universal art of manufacturing an intoxicating liquor from grain or berries (for, as Byron, with too great anthropological truth, justly re- marks, "man, being reasonable, must get drunk") he at least drank his aboriginal beer or toddy from the capacious horn of a slaughtered aurochs. That was the kind of human being who alone inhabited France and England during the later pre-Glacial period. A hundred and seventy thousand years elapse (as the play-bills put it), and then the curtain rises afresh upon neolithic Europe. Man meanwhile, loitering somewhere behind the scenes in Asia or Africa (as yet imperfectly explored from this point of view), had acquired the important arts of sharpening his tomahawks and producing hand-made pottery for his kitchen utensils. When the great ice-sheet cleared away he followed the returning summer into Northern Europe, an- other man, physically, intellectually, and morally, with all the slow ac- cumulations of nearly two thousand centuries (how easily one writes the words ! how hard to realize them !) upon his maturer shoulders. Then comes the age of what older antiquaries used to regard as primi- tive antiquity — the age of the English barrows, of the Danish kitchen- middens, of the Swiss lake-dwellings. The men who lived in it had domesticated the dog, the cow, the sheep, the goat, and the invaluable pig ; they had begun to sow small ancestral wheat and undeveloped barley ; they had learned to weave flax and wear decent clothing ; in a word, they had passed from the savage hunting condition to the stage of barbaric herdsmen and agriculturists. That is a comparative- ly modern period, and yet I suppose we must conclude, with Dr. James Geikie, that it isn't to be measured by mere calculations of ten or twenty centuries, but ten or twenty thousand years. The perspective of the past is opening up rapidly before us ; what looked quite close yesterday is shown to-day to lie away off somewhere in the dim dis- tance. Like our palaeolithic artists, we fail to get the reindeer fairly behind the ox in the foreground, as we ought to do if we saw the whole scene properly foreshortened. On the table where I write there lie two paper-weights, preserving from the fate of the sibylline leaves the sheets of foolscap to which this article is now being committed. One of them is a very rude flint hatchet, produced by merely chipping off flakes from its side by dex- terous blows, and utterly unpolished or unground in any way. It belongs to the age of the very old master (or possibly even to a slight- ly earlier epoch), and it was sent me from Ightham, in Kent, by that indefatigable uneartber of prehistoric memorials, Mr. Benjamin Har- SKETCH OF M. PIERRE E. BERT HELOT. 113 rison. That flint, which now serves me in the office of a paper-weight, is far ruder, simpler, and more ineffective than any weapon or imple- ment at present in use among the lowest savages. Yet with it, I doubt not, some naked black fellow, by the banks of the Thames, has hunted the mammoth among unbroken forests two hundred thousand years ago and more ; with it he has faced the angry cave- bear, and the original and only genuine British lion (for everybody knows that the existing mongrel heraldic beast is nothing better than a bastard modification of the leopard of the Plantagenets). Nay, I have very little doubt in my own mind that with it some aesthetic an- cestor has brained and cut up for use his next-door neighbor in the nearest cavern, and then carved upon his well-picked bones an interest- ing sketch of the entire performance. The Du Mauriers of that remote age, in fact, habitually drew their society pictures upon the personal remains of the mammoth or the man whom they wished to caricature in deathless bone-cuts. The other paper-weight is a polished neolithic tomahawk, belonging to the period of the mound-builders, who suc- ceeded the Glacial epoch, and it measures the distance between the two levels of civilization with great accuracy. It is the military weapon of a trained barbaric warrior as opposed to the universal im- plement and utensil of a rude, solitary, savage hunter. Yet how curious it is that, even in the midst of this " so-called nineteenth cent- ury," which perpetually proclaims itself an age of progress, men should still prefer to believe themselves inferior to their original an- cestors, instead of being superior to them ! The idea that man has riser is considered base, degrading, and positively wicked ; the idea that he has fallen is considered to be immensely inspiring, ennobling, and beautiful. For myself, I have somehow always preferred the boast of the Homeric Glaucus, that we, indeed, maintain ourselves to be much better men than ever were our fathers. — Cornhill Magazine. -♦*♦- SKETCH OF M. PIERRE E. BERTHELOT. "TNTIL a few years ago, investigation in organic chemistry was vJ pursued almost wholly by the road of analysis. As Gerhardt wrote in his treatise: "The chemist did everything in opposition to living Nature. He burned, destroyed, and worked by taking apart, while the vital force operated by synthesis or putting together, to reconstruct the edifice which chemical forces would destroy." The chemist was, in fact, a great destroyer. He could isolate the essence from a flower, and could destroy that essence and determine its chem- ical composition, but he was powerless to reconstruct the destroyed perfume, and could not even conceive that such a thing was possible. It is the chief title to fame of M. Berthelot that he introduced the VOL. XXVII. — 8 n4 THE POPULAR SCIENCE MONTHLY. synthetic method into organic chemistry, and devised a system of processes hy means of which we are able to create organic compounds by the direct combination of their constituent radicals. Pierre Eugene Marcellin Berthelot was born in Paris, Octo- ber 25, 1827. He was the son of a physician of some distinction, and while a student in one of the lyceums of Paris showed marked tastes for philosophical studies and chemical research, so that, when the time for the contest came, he easily won the honors in philosophy. Then, following his favorite pursuits, he occupied himself especially with studies of the acids and fatty bodies, and of fermentations. In 1851 he became attached to the College de France as preparator in the course of chemistry, in which position he was assistant to Balard. In 1854 he propounded his theory of polyatomic alcohols, and was in the same year made a Doctor in Science. In 1859 he was appointed a Professor in the Superior School of Pharmacy. In 1861 he received the Joecker prize from the Academy of Sciences for his experiments in the artificial production of chemical substances by synthesis. In 1864 he was made a Professor of Organic Chemistry in the College de France in a chair which had been created especially for him, in which he was instructed to advance his own ideas, and to treat in his lectures especially of his own discoveries. M. Berthelot entered upon the researches in synthesis, which give him his strongest title to fame, in 1854. Berzelius had said that, al- though we may produce with inorganic bodies a few substances hav- ing a composition analogous to that of some organic ones, the imita- tion is too restricted to justify us in hoping that we shall be able to produce organic bodies in the same sense that we have frequently succeeded in confirming the analysis of inorganic bodies by perform- ing the synthesis of them. Yet, when this was said, Wohler had already performed the synthesis of urea ; and a few other syntheses had been made, but they were so isolated, so insignificant, and so barren of fruit, that all attempts to constitute organic bodies by bring- ing together the elements of which they are composed were, as a rule, regarded as chimerical. The law and the manner of the formation of the organic matters which enter into the composition of the living being were unknown ; the question whether those substances were chemical in their character, or depended for their existence and main- tenance upon a peculiar vital force, had been started, but the discus- sion of it had not been seriously entered upon. M. Berthelot began to give his attention to the solution of this problem very early in his •scientific career. One of the first syntheses he performed was that of formic acid, and this was used as the basis of his further researches. Regarding this substance as formed by the union of water and carbonic oxide, he brought about a compound of that character through the intervention >©f potash, and secured the result he sought. Other syntheses followed SKETCH OF M. PIERRE E. BERTHELOT. 115 this one, conducted, like it, with very simple compounds, till he was finally led to the artificial composition of the carburets of hydrogen. Among his most important experiments in this line was the artificial production of alcohol from defiant gas. Alcohol once obtained syn- thetically, he had a station whence he could pursue his investigations in various directions. It was not a long step from this to the compo- sition with the same elements (oxygen, hydrogen, and carbon) of a number of volatile organic substances — such as the oils of garlic, mus- tard, etc. — and then to the formation of glycerine. With these pro- cesses he had built up by synthesis what we might perhaps call the first story of organic chemistry. To complete his work it was neces- sary to produce the saccharine and albuminous substances which con- stitute what might be called, repeating our figure, the second story of the edifice — a problem of a more difficult character, because those sub- stances are less stable in their nature, and are more completely decom- posed under energetic chemical reactions. On this subject M. Berthe- lot said, several years ago : " The reconstitution of the saccharine and albuminoid principles is the final object of organic chemistry, the most remote one indeed, but also one of the most important, on account of the essential part which these principles play in our economy. When science attains it, it will be able to realize the synthetic problem in its whole extent — that is, to produce, with the elemeuts and by the play of molecular forces alone, all the definite natural compounds and all the changes which matter undergoes in the bodies of living beings." "The labors of M. Berthelot in this line," says an enthusiastic French biographer, " constitute one of those events which change the aspect of things, not only by the new processes which they have devel- oped, or by the substances, more or less known, which they have given the means of reproducing, but because they have taken hold bodily of one of the strongest intrenched ideas of mankind and overthrown it. We had been taught that all the complex substances constituting plants and animals were produced wholly under the influence of a special vital force peculiar to organized beings. When it came to verifying the facts in the case, it was found that Nature acts in a more simple way than we had thought, and that she employs those chemical affini- ties that control the metamorphoses of matter equally in executing those immense earth-convulsions that stir the foundations of countries and overthrow cities, and in perfuming a flower by the distillation, molecule by molecule, of its essential oil." The fruits of M. Berthelot's investigations in this department of research have been given in a number of publications, among which we may name the " Combinaisons de la glycerine avec les acides, et reproduction des corps gras neutres" ("Combinations of Glycerine with the Acids, and Reproduction of Neutral Fatty Bodies"), 1860 ; various memoirs in the " Annales de physique et de chimie" ; " Chimie organique fondee sur la synthese " (" Organic Chemistry founded on n6 TEE POPULAR SCIENCE MONTHLY. Synthesis ") 1860 ; and " Lecons sur les methodes g&n&rales de synthese en chimie organique " (" Lessons on the General Methods of Synthesis in Organic Chemistry "), a course of lectures in the College de France, 1864. M. Berthelot has also pursued elaborate researches in specific heat, and in tbe relations between the heat developed in composition and decomposition, and the force of affinity. On the subject of the rela- tions of specific heat with the composition of bodies he said, in 1873, in a discussion in tbe French Academy with M. Dumas : " Tbe study of tbe specific heats established by tbe most recent researches tends to prove that there is a positive characteristic which, it seems to me, distinguishes tbe elements of modern chemistry from its compounds, and sbows tbat no known compound body ought to be considered as of the same order as an actually simple one. The importance of such a characteristic can not be doubted, and it becomes greater on account of the mechanical meaning which modern theories attach to specific heat. . . . Nevertheless, exaggerated conclusions must not be drawn from such an opposition between the mechanical and physical charac- teristics of our simple and compound bodies. If our elements have not as yet been decomposed, and appear not to be decomposable by tbe forces which are at present at the command of the chemist, noth- ing compels us to assert that they are not decomposable in another way than our compounds are ; as, for instance, as Mr. Loekyer asserts, by means of the forces acting in cosmical space. Nor does anything prevent that such a discovery as that of voltaic electricity would enable tbe chemists of tbe future to overpass tbe limits which are imposed upon us. The possible fundamental identity of tbe matter constituting our elements, and the possibility of transmuting into one another the so-called elements, can, moreover, be admitted into the category of more or less plausible hypotheses without it necessarily resulting that there is a single really existing matter of which our actual elements represent unequal states of condensation. In fact, nothing compels us to conceive the existence of a final decomposition which shall tend necessarily to reduce our elements either to more simple bodies, from the addition of which they arise, or to multiples of a single elementary ponderable xmit." M. Berthelot's views of the relations between chemical affinity and the intensity of chemical action were presented in his " Essai de m6ca- nique chimique fondee sur la thermo-chimie " (" Essay on Chemical Dy- namics based on Thermo-Chemistry "), 1880, of which Mr. M. M. Patti- son Muir said, in " Nature," that its publication " marks an important point in tbe advance of modern chemistry." Among the more recent investigations which M. Berthelot has pursued in the light of his thermo-cbemical theories are those into the properties of explosives and the laws of the propagation of explosions. CORRESP ONDENCE. 117 CORRESPONDENCE. FRUCTIFICATION OF THE FIG. Messrs. Editors: DEAR SIRS : Some time ago I wrote to my son, Grant Allen, to say that, in that special portion of his article (" Queer Flowers") which referred to the fructifi- cation of the fig, there must, I thought, be some mistake, for I had seen a fig-tree bear a large crop of fruit, and was sure that no such pains had been taken with it as that referred to in the article in question. To this I received yesterday (March 11th) the following reply, which, though intended only for myself, I think I break no confi- dence in publishing : " The fig-tree ques- tion," says he, "puzzled me myself much, long ago, for the capvifico doesn't grow in England, and fig-trees bear abundantly. But all the authorities arc unanimous, and I can't go against them. There is a vast literature on the subject, caprification as they call it, and Miiller in his ' Fertilization of Flowers ' gives a list of ten separate works dealing with it." So that, if he has erred, he has erred cum patribus. So far for my son. Now Miiller, who is a specialist on this subject, and the latest and very highest authority, tells Us (see " The Mechanisms of Flowers," part iii, page 521) that "the latest researches (377, Ficus carica, L.) con- firm the fact, which Linnaeus (416 A.) was aware of, that the so-called caprificus which bears inedible fruit, and the fig-tree, culti- vated for the sake of its fruit from time immemorial, stand in the relation of male and female to one another. Fertilization is effected by a wasp. ... In most cases, each crop of figs, whether of the fig-tree or the caprificus, brings only flowers of one sex to maturity." Again (p. 522): "While the fruit of the caprificus, whose only use is to supply pollen, remains hard and withers on the tree, or falls off without be- coming sweet, the fruit of the fig-tree, when the seeds ripen, becomes sweet and juicy, and so attracts birds which disseminate the seeds. From the most ancient times, as long as the fig-tree has been cultivated, its artificial fertilization by means of the cap- rificus, or so-called caprification, has been practiced," and so on. How are we to reconcile all this with the very lucid exposition and array of facts of your able correspondent in the February number of " The Popular Science Monthly." I confess I think your correspondent is in this particular right. Only that I do not wish to venture a guess — never permissible on a question of science, save tentatively — I might make one here as to how these dif- ferences might be reconciled, but I forbear. Though my son is a keen and close ob- server of Nature, and a good judge of the men to be relied on for such facts as, in his yet short life, he could not have scrutinized himself personally, yet as his more especial object is to get at the heart of his facts, to read their hidden meaning, and to show how whole continents of facts, apparently dis- connected and unrelated, are yet bound to- gether by the strongest ties of consan- guinity or more close or distant relationship, he has very frequently to go to the works of able specialists of repute in order to learn from them what they have observed. Thus, for example's sake, in a late article of his in the " Cornhill Magazine " (" Go to the Ant ") he had, as is obvious, to have recourse to the vast stores of observations accumulated by many able specialists in many parts of the world. Now, it is quite possible that some of these observations may in time come to be questioned by more exact observers ; still, in a case like this of the fig-tree, when all practical men and scientific observers have coincided in opin- ion, and where " all authorities " have for over a century been " unanimous,'1'' a writer is to be pardoned for thrusting aside a diffi- culty in his own mind, in deference to the practical judgment of the ages and the de- cision of all experts in the case. I sent my son by to-day's post the num- ber of "The Popular Science Monthly" which contained the letter of your corre- spondent ; but I wish it to be borne in mind that the reply here given is mine, not his, save in the few words quoted from a, private letter and dashed off by him in great haste. His reply, on seeing your correspondent's letter, might be very different. Yours very truly, J. Antisell Allen. March 12, 1885. Messrs. Editors : In the February number of " The Popular Science Monthly," Mr. George Pyburn, of Sacramento, says, " I have yet to see the first seedling fig," and suspects, therefore, that the seeds are generally infertile. In 1878 I planted the seeds of an im- ported white Smyrna fig. They germi- nated abundantly, and, in the fourth year from planting, my seedling fig-tree bore fruit. I shall try this year a similar experi- ment with a California fig. I anticipate a similar result. The seeds are so small that they require care. They should be planted n8 THE POPULAR SCIENCE MONTHLY. in a box, covered shallow with fine sand, and regularly watered with a sprinkler. I think figs generally are self-fertilizing. I had one tree, however, whose fruit uni- formly fell when about two thirds grown. I ascribed this to want of fertilization. Possibly the presence of the caprifico might have changed results. If so, it would follow that some varieties are self-fertilizing and others not. The " fig-wasp " is unknown here. The " novel phenomenon " related by Mr. C. G. McMillan may be found dupli- cated, though not in precisely the same way, in Northern Mississippi. His fossil leaves had retained their color during untold ages. In the other case it was the resin of the pine- tree. Near the village of Iuka was lying, some twenty years ago, and perhaps is still, a petrified pine-log about two feet in diame- ter, a ten-pound fragment of which lies here in my study. Not only does the stone re- tain the color and appearance of pine-wood, but the petrified resin has the color, semi- transparency, and general appearance of real resin. The surface-land is eocene. Isaac Kinley. Los Angeles, Cal., March 11, 1S85. SAMP AND HULLED CORN. Messrs. Editors : Mattieu Williams, in article 42 of his " Chemistry of Cookery " (" Popular Science Monthly " for January), says : " Before pro- ceeding fnrther I must fulfill the promise made in No. 39, to report the result of my repetition of the Indian process of prepar- ing samp. I soaked some ordinary Indian corn in a solution of carbonate of potash, exceeding the ten or twelve hours specified by Count Rumford. The external coat was not removed even after two days' soaking." He suspects the corn was too old and dry, and that the Indians used new or freshly gathered grain. In the first place, this is not the way to prepare samp. Samp is the Anglicized In- dian name for maize parched and pounded. It came afterward to be the name for the new corn, pounded or coarsely ground. This being done before the kernels were fairly dry, it was much prized for mush or hasty- pudding. The prepared Indian corn he refers to is called in New England hulled corn. My grandmother, whose parents were contem- porary with and from the same part of the country as Count Kumford, was famous for her hulled corn. That this method of preparing corn for food was learned from the Ind'ans is un- certain. It was probably a Yankee inven- tion of early date. Grandmother's way was to put a peck of old, dry maize into a pot filled with water, and with it a bag of hard-wood ashes, say a quart. After soaking a while it was boiled until the skins or hulls came off easily. The corn was then washed in cold water to get rid of the taste of potash, and then boiled until the kernels were soft. Another way was to take the lye from the leaches where potash was made, dilute it, and boil the corn in this until the skin or hull came off. In the experiment tried by Mr. Williams, his solution of carbonate of potash was not of sufficient strength, or, if it was, the maize or corn should have been boiled. It makes a delicious dish, eaten with milk or cream. In the early days of New England, maize was the principal grain, and was designated corn, which is the significance of the name now in all parts of the Union. Ground maize is called in New England " Indian- meal," and mixed with one third of rye- meal, fermented and baked, once consti- tuted the principal bread of the whole coun- try. It was called " rye-and-indian," pro- nounced ryningen. Boston brown bread is an imitation of it. Baked Indian is still a common appellation for a corn-meal pud- ding that strikes a stranger as a reminis- cence of cannibalism. P. J. F. Clinton, Iowa, Marcli 20, 1885. EDITOR'S TABLE. ILLITERACY AS A SOURCE OF NATIONAL DANGER. A GREAT deal of attention has late- ly been drawn to this subject, and in certain quarters an attempt has been made to " boom " it in a manner that can hardly be pronounced entirely disinter- ested. In certain educational journals, for example, teachers are urged to peti- tion the national Legislature for the passing of the "Blair Bill," on the ground that it will improve their own remuneration. One form of petition, which we find printed for the conven- ience of teachers, states that "igno- rance among the masses of the people now exists to such a degree as to threaten the early destruction of the free institutions of the republic," and that therefore a system of free schools EDITOR'S TABLE. 119 " should be in part established and, temporarily at least, supported by con- tributions from the overflowing Treas- ury of the United States." The word "temporaiuly" here will raise a smile on the lips of those who remember how often temporary protection for "our infant industries " has been applied for, and how invariably the protection so accorded has become a permanent thing. Infant industries that are nourished on " protection " never emerge from the infant condition. However they may extend and expand, they never volun- tarily forego the leading-strings or the pap-bottle ; and so we shrewdly suspect it would be with the schools " tempo- rarily " assisted by the Federal Govern- ment. If, in the course of a few years, they demonstrated their ability to dis- pense with such assistance, they would do what has seldom been done in this world. It is a most unusual thing for any organism to close an easy channel of alimentation, in order to depend ex- clusively upon one more difficult. Let the Treasury of the United States once begin to overflow in the way of aid to education "on the basis of illiteracy," it may go on overflowing. The " basis " is not likely to contract, but rather to widen out from year to year. The question, however, deserves careful consideration. Is the stability of our institutions threatened by the ignorance of the electorate? By " illit- eracy " is understood the condition of being unable to read or write; and we are asked to believe that our system of government stands in peril on account of the extent to which illiteracy as thus defined prevails. The language used would point to the conclusion that il- literacy is now a more serious evil than at any previous period of our history. The facts, however, do not support any such conclusion. The census of 1870 gave the total number of white males of voting age unable to write as 748,970. From 1870 to 1880 our population in- creased thirty per cent. Had the num- ber of illiterates remained, therefore, relatively stationary, we should have had in 1880 not less than 973,661 white voters unable to write ; instead of that, the census for that year shows the num- ber to be 886,659 only, a decidedly re- duced proportion. It is true, on the other hand, that, among the colored population, education is not keeping pace with the natural increase of num- bers, but this fact alone does not justify the interference of the Federal Govern- ment to supplement the educational work that is now going on. "What has not been shown as yet, so far as we are aware, is that the so- called illiterate classes are a specific source of danger to our institutions. If we review the several crises of our his- tory, we shall probably find that those who have done most to bring on these crises have been, for the most part, men quite able to read and write. The Tilden-Hayes imbroglio could not cer- tainly be traced to the ignorance of the electorate. Maine is a highly educated State, and yet it was precisely there that a few years ago a condition of war almost supervened in connection with the State elections. The false returns which kept this city, and in a less de- gree the whole Union, in a condition of fever-heat for days together last fall, had nothing to do with illiteracy, quite the contrary. Even the Cincinnati riot was not the work of men who could not read or write, but rather of citizens quite competent in these respects, but who had momentarily lost their heads. The fact is, the citizens who can read and write have everywhere the power in their own hands, and if they are only willing to discharge their duties, pri- vate and public, in a proper manner, the non-reading and non-writing ele- ment in the population will give them comparatively little trouble. There is, however, another view to be taken of the matter. If our schools are not as efficient as they should be, and if an undue proportion of the whole population escapes the civilizing influence of education, what is the- 120 THE POPULAR SCIENCE MONTHLY. cause ? We do not hesitate to say that the chief cause is one which no Gov- ernment action, State or Federal, can ever reach — viz., defect of home disci- pline. The hoy who will not attend school, or who, attending school, learns nothing, is the hoy accustomed to re- bellion at home, or the boy whose par- ents are themselves too negligent and vicious to care whether he learns any- thing or not. It is no doubt the case that a certain portion of the population of these States is being brought up in partial or total savagery. Not for want of schools, however, for schools abound. The evil is deep-seated, and can only be reached by the vigorous action of pub- lic opinion, and by wise measures of reform in connection with the admin- istration of justice. When we explain why it is that our educational systems fail altogether to reach a certain ele- ment in the population, we explain, also, why the work of education is in many cases so shallow, and why it even seems at times to do more harm than good. Everything depends on the spirit with which it is approached. A well-known figure in contemporary fic- tion— Maud Matchin — well illustrates the work of the high school or acad- emy on the mind of a vain and vulgar girl, who sets no value upon education, save as it may help her to a position in the world, and the vices of whose char- acter are therefore brought only into stronger relief by her wretched varnish of accomplishments. And here we see the folly of all schemes that would set the Federal Government at work to repair the weak places of education throughout the States and Territories. All that is proposed is that reading and writing should be made universal ac- complishments, so as to remove the re- proach and danger of technical "illit- eracy." But there is absolutely no guarantee that the voter newly in- structed to read and write would be any better man than he was before. If our high-schools are turning out Maud Matchins by the score and hun- dred, and if youths by the thousand leave school to pursue a career of "smartness," without one thought of social responsibility, it is evident that the mere extension of educational facil- ities is a much less pressing need than the moralizing of the whole business of education. Philosophers have told us that it is perfectly possible to educate in an intellectual sense without touch- ing one single moral chord ; and daily experience confirms the truth of the statement. Instead, therefore, of en- gaging the Federal Government to es- tablish more schools, we would engage the whole community to place the schools that now exist upon a higher moral plane, and to render them more effectual in their working by a higher quality of home influence. It is in the home above all that reform is needed ; but, unhappily, the school has of late years so dwarfed the home, so inter- posed between the parent and his natu- ral and proper responsibility toward his child, that to preach " home influence " to-day is almost like raising one's voice in the wilderness. Things are badly complicated ; one thing only is certain, and that is, that more State interfer- ence will not help to clear up the com- plications, or to put things on a sound basis. It is needless, we trust, in conclud- ing these remarks, to say that we yield to none in the importance we attach to education rightly understood. By edu- cation, however, we do not understand merely the ability to read and write, and we are not fully persuaded that our institutions would be any safer than they are to-day if every child in the country over twelve years old could both read and write. What we know for certain is, that an individual able to do both may be in a condition of very unstable intellectual equilibrium, and so, we believe, might a whole commu- nity of such individuals. What we need to improve our intellectual state is not an increase of activity on the part of the Government, but deeper convictions EDITOR'S TABLE. 121 of social duty throughout the commu- nity, and, above all, a livelier sense of parental responsibility. Let us have these things, and the republic will be safe, and education will begin to be truly humanizing and truly progres- sive. A TEST OF PHILOSOPHY. Theee is now a pretty decided agree- ment among the intelligent and unpreju- diced that Herbert Spencer takes rank as the first philosopher of England, and G. H. Lewes many years ago declared him to be the only English thinker who has originated a philosophy. How much this may mean is well intimated by the remark of Mr. Lester F. Ward, that, " when we have reached England's greatest in any achievement of mind, we have usually also reached the world's greatest." But there is still room to regard the compliment as equivocal, for the ques- tion remains, What is it to be " the first philosopher " ? To be first and alone in a department of thought obviously means little or much, according to the grade of intellectual work involved. Philosophy is a vague term, and, as ex- perience shows, may imply the lowest as well as the highest exercise of the mind. As applied to systems of specu- lation in pre-scientific ages, it no doubt represented the best mental effort then possible. But as applied in these times to similar speculations, with little refer- ence to the rise of modern knowledge, it is not the highest kind of intellectual performance. True philosophy — the deepest and largest understanding of things — must be so far scientific in spirit and method as to place facts first, and work in subordination to them. The philosophy that is typified by the Concord school, which is most inter- ested in the transcendental, which gives imagination the lead, leaves vul- gar facts to the Gradgrinds, and is as jealous of science as theology, is not a very exalted form of mental exertion, and to be first in it is no great compli- ment. Philosophy, to achieve its high- est objects, must now begin with the patient study of long-contemned reali- ties ; must discipline the imagination, must work in subordination to estab- lished knowledge, and aim to bring out profounder truth for the practical guidance of man in ordering the course of his life. To be the first philosopher of the foremost nation of the world from this point of view is exalted praise, and this is the position that Mr. Spencer has undoubtedly won. His philosophy is based upon Nature, is limited to Na- ture, is subordinated to science, and is such a presentation of the laws and order of the world as bears imme- diately upon questions of human con- duct. It is synthesis of the principles which become all-determining rules in the practical sphere of human action. It bears upon religion, upon politics, upon education, and upon social and domestic experience, with the authority of science and the full power of a veri- fied system of natural laws. It was long a reproach to Spencer that he un- dertook to deal with so many subjects, but it is now perceived that this was but the inevitable consequence of that comprehensive method which the ad- vance of modern knowledge had made possible and imperative. We have been led to these remarks by a circumstance, not in itself of much importance, but which is yet significant as giving a new attestation of the worth of Spencer's philosophy in its practical bearings. Mr. Spencer has applied his philosophical views to the subject of education, and his little treatise upon the subject has been rendered into all the languages of the civilized world. And now, by an appeal made to the judgment of English teachers, the ver- dict has been rendered that the first of English philosophers is also the first of English educators. We see, by the Lon- don " Journal of Education," that an extra prize was offered for the best list 12: THE POPULAR SCIENCE MONTHLY. of the seven greatest living educationists classed in the order of importance. A great number of lists were sent in, and the prize was awarded to "X. Y. Z." for the following list : 1, Spencer ; 2, Huxley; 3, Wilson; 4, Thriug; 5, Miss Buss ; 6, Laurie ; 7, Quick. Besides this premium list, in which the name of Spencer was first in importance, his name also appeared in seventy -two other lists, while Bain appeared in fifty; Huxley, thirty - eight ; Thring, thirty-six ; Miss Beale, thirty-four ; Miss Buss, thirty-three ; B. H. Quick, thirty- two ; E. A. Ahbott, tliirty-one ; A. J. Mundella and J. G. Fitch, twenty- nine ; J. Buskin and M. Arnold, twenty- eight. It has been said in deprecation of Spencer that " only the Seven Sages can understand him " ; but it seems that practical teachers can sufficiently understand him to be able to form a very appreciative estimate of his posi- tion in the field where they are the most competent judges. LITERARY NOTICES. American Political Ideas : Viewed from the Stand-point of Universal History. Three Lectures delivered at the Royal Institution of Great Britain, in May, 1880. By John Fiske. New York : Harper & Brothers. Pp. 158. Price, $1.00. As many will be gratified to learn, Mr. Fiske has at length published the brief course of lectures upon " American Political Ideas " which attracted so much attention at the time of their delivery in England, and subsequently in this country. They afford an excellent popular illustration of the sci- entific method in politics, and as an original statement of the place of American politi- cal institutions in the progress of civilization they will be read with deep interest and pa- triotic pride by multitudes of our thought- ful citizens. Under the three titles of " The Town-Meeting," "The Federal Union," and "Manifest Destiny," the author gives us a pregnant discussion of the ideas that are at the foundation of true political devel- opment, of their historic growth, and the vast consequences to the world of their pres- ent success and their future ascendency. Mr. Fiske takes the "town-meeting," the idea of which is so thoroughly familiar in this country, as the elemental basis of our political system. He devotes his first lect- ure to the consideration of it as involving the principle of local self-government. The present or absence, in various degrees, of institutions corresponding to this, in differ- ent countries, is shown to be intimately connected with the progress of free govern- ment, and to have exerted a powerful con- trol over the character and destiny of na- tions. Having treated of the corporate units of society, the township, the village, the parish, or whatever grouping becomes the seat and center of local self-control, Mr. Fiske passes in his second lecture to the important prob- lem of their combination or aggregation into coherent extended political organiza- tions. In communities of despotic type this is done by conquest and centralized military power. But wherever and to the degree in which civilization or civil agencies have re- placed militancy, the principle of represen- tation arises, and the freer mode of gov- ernment takes the form of federal union. Mr. Fiske illustrates the progress and vicis- situdes of the federal principle very im- pressively from Greek, Roman, and modern history, and in the United States, where representation and federal unity have re- ceived their largest application. The third lecture, on " Manifest Destiny," is a brilliant and powerful exposition of the vast scale and comprehensive interaction of the political forces that are now so po- tent in civilization, and that are destined to work out grand results in the future. He shows that civilization is to conquer through peace ; that the militant countries will have to disband their armies under the irresistible influence of the industrial competition of nations ; and that the pacific federation of great communities is as certain to replace brute force in the politics of the civilized world as civil processes have replaced arbi- trary violence in the private relations of men. The real significance of the Ameri- can civil war is shown to consist in the vin- dicated strength and supremacy of the great pacific and constructive federative principle which is to dominate in the political future LITERARY NOTICES. 123 of civilization ; and the data are given by which to forecast the stupendous future of the English race, not only on this continent, but throughout the world. Although written with sobriety, to be submitted to the critical judgment of a cul- tivated audience, yet these lectures are a good deal stirring and stimulating in their effect upon the reader's mind. This is due both to the charm of the presentation and to the magnitude of the elements of the author's imposing theme. " The stand-point of universal history" affords an exciting outlook, and Mr. Fiske gives his readers a clear command of the position. The author of "Cosmic Philosophy," with whom the conception of universal evolution has be- come part of his mental constitution, is well prepared to handle historical questions in the fullest breadth of their bearings, and the interest of the present book is chiefly derived from this preparation of its author. It may, in fact, be commended as a spe- cially instructive study in political evolution. This is well explained by Mr. Fiske in the following prefatory passage : In the three lectures now published I have en- deavored to illustrate some of the fundamental ideas of American politics, by setting forth their relations to the general history of mankind. It is impossible thoroughly to grasp the meaning of any group of facts in any department of study until we have duly compared them with allied groups of facts ; and the political history of the American people can be rightly understood only when it is studied in connection with that general process of political evolutiou which has been going on from the earliest times, and of which it is itself one of the most important and remarkable phases. The gov- ernment of the United States is not the result of special creation, but of evolution. As the town- meetings of New England are lineally descended from the village assemblies of the early Aryans; as our huge Federal Union was long ago foreshadowed in the little leagues of Greek cities and Swiss can- tons—so the great political problem which we are (thus far successfully) solving is the very same problem upon which all civilized peoples have been working ever since civilization began. How to iasure peaceful concerted action throughout the whole, without infringing upon local and individual freedom in the parts, this has ever been the chief aim of civilization viewed on its political side ; and we rate the failure or success of nations 'politically according to their failure or success in attaining this supreme end. When thus considered in the light of the comparative method, our American history acquires added dignity and interest, and a broad and rational basis is secured for the detailed treatment of political questions. The Nature and Reality of Religion. A Controversy between Frederic Harrison and Herbert Spencer. With an Intro- duction, Notes, and an Appendix on the Religious Value of the Unknowable, by Count D'Alviella. New York : D. Ap- pleton & Co. 1S85. Pp. 218. Price, cloth, $1 ; paper, 50 cents. That there is a " chaos of discordant opinion " in the religious world is a common remark, and, superficially regarded, the re- mark is true enough. There are divers great religious systems accepted by vast multitudes which exemplify profound diver- sities of belief ; and these systems are bro- ken up into sects innumerable, all marked by divergences of religious opinion. Yet this state of thought is by no means a "chaos"; there are order and law in it. Religious phenomena exhibit their predict- able sequences of cause and effect. It may be counted on that people generally will stick to the faith into which they were born, and to the sect in which they were brought up, regardless of any question of the ration- ality of the creed they hold. Indeed, the te- nacity with which, generation after genera- tion, they cling to the accidental tenets they inherit, is an element of order which gives to religious organizations their stability and permanence. Yet the condition of the religious world is by no means one of absolute immobility and stagnation. To the degree in which the human mind is active, religion shares the result. While many are quiescent, a few are ever inquiring, and, with increasing enlightenment and growing knowledge, the superstitious element in religion gradually diminishes and disappears. This, too, is an orderly change, and goes on in the religious world by the established laws of progress. Such controversies as those of Spencer and Harrison are, hence, quite in the course of things. With whatever considerations of personality they may be mixed up, they are products of religious advancement, and still further contributions to it. The pres- ent discussion, however, is of more than usual significance, as it is not occupied with incidental but with fundamental religious questions. The conception of progress in religion is unquestionably revolutionizing and destructive, and no problem is more profound or momentous than that which 124 THE POPULAR SCIENCE MONTHLY. seeks to determine the final result of relig- ious evolution. However kit is to be com- mended, or however deplored, the advanced mind of this generation is deeply engaged with the most radical religious questions; and it is fortunate, when, as in the present case, the contestants are men of earnest- ness, sincerity, and reverence, as well as of fearlessness, brilliancy, and power. To the readers of the " Monthly " nothing need be said in regard to the special merits of this controversy, except that they will find the volume convenient from the completeness of the views it presents. Land -Laws op Mining Districts. By Charles Howard Shinn. Baltimore: N. Murray. Pp. 83. Price, 50 cents. Mining - Camps. By Charles Howard Shinn. New York : Charles Scribner's Sons. Pp. 316. Price, $2. These two works present the results of an investigation into the history of mining- camps, undertaken with a hope of giving the forms of social organization manifest in the early " districts " of the Sierras, Coast Range, and Rocky Mountains, their proper place in the story of institutional develop- ment on American soil. The work first named is one of the " Johns Hopkins Uni- j versity Series of Studies in Historical and j Political Science " ; and the editor of the se- j ries introduces it with the intimation that it is a "natural, though unconscious, continua- tion of Mr. Johnson's study of ' Rudiment- ary Society among Boys,' " which we have already noticed, " and that it might be called 4 Rudimentary Society among Men.' " The second work is of larger scope and more fully wrought out. Mr. Shinn has done a good work in elucidating some peculiar phe- nomena of social and political development. What his essays teach may be illustrated by quoting one of the passages in "Mining- Camps": "In every important particular the organizations of the typical mining- camps, which we have been considering, offer sharply-outlined contrasts. Camp-law has never been the enemy of time-tried and age-honored judicial system, but its friend and forerunner. Axe of pioneer and pick of miner have leveled the forests, and bro- ken down the ledges of rock, to. clear a place for the stately structures of a later civilization. Rude mountain courts, rude justice of miner-camps, truth reached by short cuts, decisions unclouded by the verbi- age of legal lexicons, a rough-hewed, sturdy system that protected property, suppressed crime, prevented anarchy — such were the facts ; and on these frontier government rests its claims to recognition as other than mob-law, and better than passionate acci- dent." " The Jukes " : A Study in Crime, Pauper- ism, Disease, and Heredity. By R. L. Dugdale. Fourth edition. New York : G. P. Putnam's Sons. Pp. 121. Price, $1.25. This book embodies the substance of a famous paper, which, first published in the report of the Prison Association for 1877, has probably done more to promote the in- vestigation of methods for the reform of criminals and the prevention of crime than any other single document of the time. It is, as the editor, Mr. Round, says in the in- troduction, " known, read, and valued wher- ever the civilization of the world has ad- vanced far enough to be alarmed at the increase of crime, and to be concerned in reducing the criminal classes." It relates the story of a large family of criminals, prostitutes, and vagrants, which infested a group of counties in New York for two or three generations, all the descendants of a prostitute who was left to go her ways for evil unrestrained by any efforts to reclaim her. A new edition has been demanded in the interest of penal science. The original paper is supplemented with further studies of criminals, and an introduction insisting on the importance of the investigations by Mr. William M. F. Round, Secretary of the National Prison Association. A Popular Exposition of Electricity. With Sketches of some of its Discover- ers. By the Rev. Martin S. Brennan. New York : D. Appleton & Co. Pp. 191. Price, 75 cents. The object of this book is to make all familiar with the essential principles, at least, of the science of electricity ; a pur- pose which none of the learned and excel- lent treatises devoted to the subject, " but so illustrated with complex and intricate mechanical diagrams as to frighten away the timid and uninitiated," seem adapted to LITERARY NOTICES. 125 effect. The author has, therefore, devoted his attention almost entirely to the explana- tion of principles, to the exclusion of me- chanics. He has aimed to exhibit the iden- tity of all the forms of electricity, and has accordingly so arranged the matter of his treatise that each succeeding form shall appear to flow naturally from its predeces- sor. For the biographical sketches, those men have been selected whose discoveries have added most to the science ; and the sketches are so distributed that each one shall be in logical juxtaposition with those branches of the science that have been most conspicuously illustrated by its subject. In the several chapters are given explanations of magnetism ; the " Mariner's Compass," statical and atmospheric electricity, galvan- ism and galvanic batteries, electro-chemical decomposition, electrotyping and gilding, electro-magnetism, the electric telegraph, magneto-electricity and dynamos, the stor- age of electricity, the telephone, the aurora borealis, and Faraday's observations on ta- ble-moving. The subjects of the sketches are Faraday, Franklin, Galvani, Volta, Oer- sted, Ampere, and Professor Morse. The Care of Infants : A Manual for Moth- ers and Nurses. By Sophia Jex- Blake, M. D. London and New York : Mac- millan & Co. Pp. 109. Price, 40 cents. The subject of this primer is a most important one, especially in view of the frightful rate of infant mortality that pre- vails, largely the result of ignorance and carelessness. The author is a most compe- tent person to discuss it. Her purpose, she says, is " to supply, in the simplest and easiest possible way, the few leading facts respecting infant existence, and to specify, as briefly and clearly as may be, the treat- ment demanded by Nature and common sense for the preservation of the frail little lives that are perishing by millions for want of it." Annual and Seasonal Climatic Maps of the United States. By Charles Deni- son, Denver, Colorado. Chicago : Rand, McNally & Co. Five Maps, in Colors, variously mounted. These maps are compiled from the re- turns of the Signal-Service Office, and are designed to show, graphically, by an equa- ble standard and on impartial author- ity, chiefly, the average amount of cloudi- ness and precipitation at every place in the United States, for the year and for each season. In addition to this, they give the isothermal lines, the directions of prevailing winds, and of winds that usually and those that do not usually bring rain or snow, ele- vation above the sea, location of mineral springs, annual, monthly, and daily ranges of temperature, and other information that can be given graphically, or in a table, re- lating to the climatology of our country. The maps can be had separately, or, as in the case of the set submitted to us for ex- amination, mounted on opposite sides of the same sheet. Controlling Sex in Generation. By Sam- uel Hough Terry. New York : Fowler & Wells Company. Pp. 147. Price, $1. This is an attempt to discover the phys- ical law influencing sex in the embryo of man and brute, and its direction to produce male and female offspring at will. The sub- ject is an important one to breeders, and the author thinks he has discovered its law, claiming that the determination of the sex of offspring in all life lies in the separate physical conditions of the two parents. In his book he shows how he has reached his conclusion, brings forward the evidence by which he believes it is sustained, and makes suggestions respecting its practical bearing. The National Dispensatory. Containing the Natural History, Chemistrv, Phar- macy, Actions, and Uses of Medicines. By Alfred Stille, M. D., and John M. Maisch, Ph. D. Third edition. Phila- delphia: Henry C. Lea's Son & Co. Pp. 1,755, with 311 Illustrations. The first edition of the " National Dis- pensatory" was published in 1879. It in- cluded descriptions of all crude drugs and chemical and pharmaceutical preparations, officinal in the Pharmacopoeias of the United States and Great Britain, together with the more important medicines of the French Co- dex and German Pharmacopoeia which were, to some extent, prescribed here, or which might serve for comparison with similar arti- cles in the English and American stand- ards ; also, of drugs not recognized by any pharmacopoeia, but often kept in the shops 126 THE POPULAR SCIENCE MONTHLY. because they were prescribed by physicians, or used in domestic practice, either entered under their own headings, or as " allied drugs " under those of more important sub- stances. With these descriptions was given such information about the botanical char- acter of plants yielding drugs, the external and structural characteristics, and the modes of preparation of drugs, their chemical prop- erties, and their physiological action as de- termined by experiment, as seemed appro- priate to the purposes of the work. The present edition may be regarded as em- bodying the pharmacopoeias of the four chief civilized nations. Those of the United States and Germany appeared at the close of 1S82, and formed the basis' of the revis- ion. The French Codex was published after the work was prepared for the press, but in time to admit of its incorporation. The British Pharmacopoeia has not been revised since 1867. Many of the newer statements have been tested and corrected by special experiments. A large number of extra- pharmacopceial medicines have been added to those in previous editions. Numerous historical notes have been added. The de- scriptions have been condensed or extended as occasion seemed to require, and micro- scopical structure has been more fully de- scribed and illustrated. While the most recent views of the physiological action, so far as it explains the curative effects of medicines, have been given, all generaliza- tions have been kept subordinate to the practical character of the work. The Gen- eral Index contains more than 3,700 more references than that of the second edition, and the Index of Therapeutics nearly 1,600 new references. The references to authori- ties in the therapeutical portion of the work have been extended. Occult Science in India and among tiie Ancients, with an Account of their Mystic Initiations, and the History of Spiritism. By Louis Jacolliot. Trans- lated by Willard L. Felt. New York : John W. Lovell Company. Pp. 275. It may be well to say, in view of the manner in which the title has been used by a certain sect, that this is apparently a real historical study and an account of phe- nomena which, whatever may be their char- acter, exist and have not been explained. The author is Chief-Justice of Chantlema- gore, in the French East Indies, and of Ta- hiti, who has, during long residence in India, given considerable attention to investiga- tions of the subject, and to observations of the practices of those who have been initi- ated into the sect of the Pitris, or ancestral shades. The book, he declares, is neither a doctrinal one nor a work of criticism. He does not feel himself called upon to decide either for or against the belief in spirits, either meditating or inspiring, which was held by those who had been initiated in the temples of antiquity, and which is the key- stone of the philosophical and religious in- struction of the Brahmans ; therefore he re- gards himself as the better able to write its history. He assumes to give " the words themselves," and set forth things as they actually were ; to interpret and explain the philosophical compendium of the Hindoo spiritists ; to tell what he saw with his own eyes, and faithfully record such explanations as he received from the Brahmans. He pays attention to the phenomena which the fakirs produce at will, which are variously regarded, but concerning which he remarks that " the facts which are simply magnetic are indisputable, extraordinary as they may seem. As to the facts which are purely spiritual, we were only able to explain those in which we participated, either as actor or spectator, upon the hypothesis that we were the victims of hallucination, unless we are willing to admit that there was an occult intervention." The Sanitary ' Engineer. Conducted by Henry C. Meyer. Volume X. June to November, 1884. 140 William Street, New York. Pp. 612. Price, $4 a year. The " Sanitary Engineer " is a journal of civil and sanitary engineering and pub- lic and private hygiene, and gives particu- lar attention to plumbing and the construc- tion and arrangement of houses, with refer- ence to sanitary conditions. The present volume contains many valuable papers; among them those relating to the Interna- tional Health Exhibition, to describing and illustrating the plumbing, heating, ventilat- ing and lighting of notable buildings, to steam-fitting and steam-heating, and the reports of various hygienic conventions. LITERARY NOTICES. 127 Johns Hopkins University Studies in His- torical and Political Science. The projectors of the " Johns Hopkins University Studies in Historical and Politi- cal Science " offer a third series of their monthly monographs, which have^ proved so valuable and instructive, to be devoted to American institutions and economies. The series will include papers on " Local and Municipal Government," "State and National Institutions," and "American Socialism " and " Economies." The numbers may be obtained separately, or the series as a whole after it is completed, from N. Murray, publication agent, Baltimore. One Hundred Years of Publishing, 17S5- 1885. Philadelphia : Lea Brothers & Co. Pp. 20. This is a memorial volume commemora- tive of the hundredth year of the publishing house whose imprint it bears. The business of the house was founded by Matthew Carey, an Irish exile, who began a daily paper in 1785, to which he soon added a monthly magazine. He and his successors then pub- lished quarto Bibles — the Douay and au- thorized versions — the Waverley Novels, the works of Fenimore Cooper, Washington Ir- ving, and other early American authors, with some encyclopedic books which evinced con- siderable boldness of enterprise for their day, and introduced the American public to the genius of Charles Dickens. Gradually the business of the house tended to medical and scientific publications, to which, giving up literary and miscellaneous works, it has of late years been exclusively devoted. No member of the house has died in the busi- ness, but each one has in his turn withdrawn in season to enjoy the fruits of his industry. The Mentor. By Alfred Ayres. New York: Funk k Wagnalls. Pp. 211. This little book., by an author already well known by his " Orthoepist," " Verbal- ist," etc., is intended " for the guidance of such men and boys as would appear to ad- vantage in the society of persons of the better sort." As the author well says, not wealth, but moral worth, supplemented with education, and enough money to make one's self presentable, are the passport to the better circles of society In the body of the work are given common - sense principles respecting what constitutes a good personal appearance and good behavior — at the din- ner-table, and in public, in conversation, in calls, and at cards, " odds and ends," and " What is a Gentleman ? " The Next Step of Progress : A Limita- tion of Wealth. By John H. Keyser, 115 Beekman Street, New York. Pp. 50. Price, 20 cents. This document expounds the principles of a new party which has been formed, or is in the process of formation, of which the author appears as one of the active or- ganizers. It proposes to " level up, not down," and to break monopoly by promot- ing a limitation of wealth. For this pur- pose, it would impose a graduated taxation on accumulating and accumulated fortunes, ranging, say, from one half of one per cent on estates of between $10,000 and $20,000, to fifty per cent on estates of $5,000,000 and upward. School-Keeping, now to do it. By Hiram Orcutt. Boston : N. E. Publishing Com- pany. Pp. 244. Price, $1. This volume embodies to a great extent fruits of the author's experience ; incidents that have happened during his school-keep- ing, and the thoughts and principles that have been suggested by them. Its design is to aid and encourage teachers who need and would profit by the experience of others ; and to awaken an interest in the subjects treated, and lead to a more extensive read- ing and study of the works of standard au- thors on pedagogics, with a more careful preparation for the important duties of their position. It is a pleasant book, and con- tains good thoughts. Diluvium : or, The End of the World. By George S. Pidgeon. St. Louis : Com- mercial Printing Company. Pp. 175, with Plates. The author's purpose in publishing this book is to invite consideration of the pos- sible consequences that may follow the exe- cution of such a project as the French one for turning the waters of the ocean into the Desert of Sahara, and forming a great inland sea there. He apprehends that the sudden transfer of so large a mass of matter 128 THE POPULAR SCIENCE MONTHLY. from one part of the earth's surface to an- other will be attended with a disturbance of the center of gravity of the planet, and with convulsions, floods, and great disasters to the continents and what is upon them. Further, "meteorological, electrical, and other phenomena of equal greatness, grand- eur, and sublimity, as those of land and water, would follow a paroxysmal move- ment of the earth." Therefore, it will be well to halt before making real so rash a scheme. Ingglish az She iz Spelt. Perpetrated by Fritz Federheld. New York: G. W. Carleton & Co. Pp. 93. Price, 25 cents. The compiler of this odd composition evidently regards the accepted English or- thography as a fetich to whose sanctity he does not consider himself bound to pay any respect ; for he holds it up to ridicule in a very amusing style by parodies, epigrams, comic poems, anecdotes, and witty extracts, the purport of all of which is to stamp the whole system as inconsistent with itself, and particular features of it as absurd. The va- riety of the sounds which are given to the groups of letters " ough " is humorously set forth in several pieces, the most noteworthy of which is Planche's squib on the pronun- ciation of the name of Lord Houghton. Other rhymes, drawn from Professor Bar- nard, Professor Gregory, and others, expose what appear to be monstrosities of spelling, but which are shown to be justified by analo- gous spellings in other words recognized as orthographic. A series of extracts from standard authors shows what was the con- dition of English spelling, at intervals of about fifty years, from Chaucer to Samuel Johnson. Practical Work in the School-Room. Ob- ject-Lessons on the Human Body. New York : A. Lovell & Co. Pp. 167. This volume embraces transcripts of lessons that have been given in the primary department of Grammar-School, No. 49, New York, and which include instructions consonant with the plan, on the subject of physiology and the effects of stimulants and narcotics. The plan of teaching comprises a model lesson, to show how each subject should be developed and taught ; a formula, embodying the principal facts presented ; questions on the formula ; directions for touching, or pointing to the part under de- scription ; questions on the lesson ; and a blackboard outline. Alice's Adventures in Wonderland, and Through the Looking-Glass. By Lewis Carrol. New York : Macmillan & Co. Pp. 192 and 224, with 92 Illustrations. Price, paper, 50 cents ; cloth, 75 cents. Two books in one, of pure nonsense and delightful absurdities, which have for sev- eral years enjoyed extensive popularity. In the first book, Alice goes down into a rab- bit-hole and has stirring adventures with the rabbit and an animated pack of cards. In the second story, she succeeds in getting into the country behind the looking-glass, where she finds everything reversed, and meets the characters of Mother Goose and English folk-lore mythology. Serapis. By George Ebers. From the Ger- man by Clara Bell. New York : Will- iam S. Gottsberger. Pp. 387. Price, 90 cents. This is a story of Alexandria in a. d. 391, under Roman rule ; one of those at- tempts to restore and present to the pres- ent age the life of antiquity, with some of the most successful of which the author's name is associated. The Wane of an Ideal. By La Marchesa Colombi. From the Italian by Clara Bell. New York : W. S. Gottsberger. Pp. 260. Price, 90 cents. A story, by a popular living Italian novelist, of contemporary village life in the north of Italy, in which " a variety of the social problems which occupy Italian thought are treated in a way which is humorous without being cynical," and having a close " which is melancholy but scarcely tragical."

This journal takes the place of " The Canadian Naturalist and Geologist," and is under the charge of an editing committee of the Natural History Society of Montreal, which is composed of T. Sterry Hunt, B. P. Penhallow, B. J. Harrington, J. Wanless, and J. T. Donald. The intention of the editors is to present both original and se- LITERARY NOTICES. 129 lected articles, more particularly those of especial interest to the Dominion. In the present number we find a history of the journal of which this is a continuation ; an account of " The Royal Society of Canada " ; a paper by Professor Dawson on " Rhizo- carps in the Palaeozoic Period ; " a descrip- tion by the Rev. Emile Petitot of " the Atha- basca District of the Canadian Northwest Territory " ; and shorter papers. "Shadows " : Being a Familiar Presentation of Thoughts and Experiences in Spirit- ual Matters, with Illustrative Narratives. By John Wetiierbee. Boston : Colby & Rich. Pp. 2S8. The author's endeavor has been to give, in a series of chapters, each of which shall be a finished one of itself, the reasons, with- out particularly saying 60, why he is a spiritualist ; or to make a familiar presenta- tion of the subject of modern spiritualism to those whom it may concern, both among its exponents, and among that wider world who feel interested in the subject, "and wish it were true," and want the " bottom facts." Maryland's Influence upon Land Cessions to the United States. With Minor Papers. By Herbert B. Adams, Ph. D. Baltimore : N. Murray. Pp. 102. Price, 75 cents. This essay constitutes the first number of the third series of " Johns Hopkins Uni- versity Studies in Historical and Political Science " — a series which is to be devoted to American institutions and economics. Among the purposes the author endeavors to serve in publishing it is to " call atten- tion to the territorial foundations of the American Union, and point out the fact that our public lands stand in the same funda- mental relation to our national common- wealth as did common lands to the village republics of New England. The great West was the Folkland of the United States ; it bound them together by economic interests when they would otherwise have fallen apart after the Revolution. To trace out the further constitutional influence of our public lands upon the development of these States, which have increased and multiplied within the national domain, as did New England parishes within the original limits vol. xxvii. — 9 of one town, this would be a contribution indeed to American institutional history." As bearing upon this point, the author out- lines a wide and varied field of research, on which it is hoped laborers will soon be en- gaged, and parts of which are to be exploit- ed in future numbers of this series. The " Minor Papers " include articles on " George Washington's Interest in Western Lands,'' the " Potomac Company," and a "National University." Egypt and Babylon, from Sacred and Pro- fane Sources. By George Ravvlinson. New York : Charles Scribner's Sons. Pp. 329. Price, $1.50. The Bible abounds in references to Egypt and the Mesopotamian empires and their af- fairs. So long as we had to depend for our knowledge of those countries in ancient times from the statements, generally half informed and often erroneous, of the Greek historians, these references were obscure and difficult to verify. The progress of archaeological discovery has put a different face upon matters. Under its light the life and history of these extremely ancient em- pires have been revealed at many points with remarkable vividness and a precision which we have hardly yet attained concern- ing some contemporary people, and the ref- erences in the Bible have been, to a very large extent, endowed with an exact signifi- cance. It is hardly necessary to say that further elucidations on points that are still dark may be anticipated from continued re- searches. It has been Mr. Rawlinson's task to collect the references, separately for Egypt and for Babylon, in the Bible, taking them nearly in chronological order, and to compare them with the facts, as related in other histories, and as inscribed in contem- porary records, on the monuments executed by the rulers and peoples of the empires to which the references are made. Van Nostrand's Engineering Magazine. Vol. XXXI, July-December, 1S84. New York : D. Van Nostrand. Pp. 524. This publication has a place of its own. It appeals especially to engineers, and to persons who are interested in the construc- tion of works beyond the sphere of ordinary builders, and in extensive applications of machinery; and its papers on subjects of 13° THE POPULAR SCIENCE MONTHLY, such class, both original and selected from foreign journals, are, as a rule, written by experts, by men who have made special study of the points they are discussing, or have had experience in the application of them. It also pays considerable attention to topics of a more general scientific charac- ter, and gives much withal that commends itself to persons who are not specialists or professionally informed, but who have an intelligent interest in the progress of the departments to which it is devoted. Proposed Plan for a Sewerage System, and for the disposal of the sewage of the City of Providence. By Samuel M. Gray, City Engineer. Pp. 146, with Plans and Maps. City Engineer Gray was deputed by the City Council of Providence, a year ago, to proceed with his assistant to Europe to in- vestigate the various plans in practical op- eration for the disposition and utilization of sewage, and upon the information thus obtained to report a plan for adoption in that city. The list of cities and works he visited, in England, Wales, Holland, France, and Germany — wherever, in fact, important sewerage-works have been undertaken, or systems for the disposition of sewage have been tried, or are under trial — shows that his inspection was a busy one. In the plan which he has devised, with the aid of these observations, he has had in view the prin- ciple which is in reality the Hamlet of the question, but is too often left out, that " no system of sewerage is complete which fails to dispose of the sewage so as to avoid its causing a nuisance." The report embodies a large mass of information, presented with commendable brevity. After an historical review of the subject, the several systems for disposing of sewage are considered as to their general principles and specifically. Among these are the systems of sewage in- terception, or dry-sewage systems, the pneu- matic systems (Licrnur, Berlier, and Shone) ; the water-carriage system ; and the systems of disposal by irrigation and precipitation; with a comparison of the different methods of purifying sewage. Although prepared only for a special object, the report might, in the absence of any other comprehensive work, serve as a general manual of the sub- ject. Tables, Meteorological and Physical. By Arnold Guyot. Fourth edition, re- vised and enlarged. Edited by William Libbey, Jr. Washington: Smithsonian Institution. Pp. 738. Professor Gdyot's original work, pub- lished in 1852, was the first of the series of " Tables of Constants," to which the Smith- sonian Institution is gradually making im- portant contributions, and has proved, by the demand which arose for it, to be the one of the series that has met the most general public want. A second revised edition was published in 1857, in which the tables were so enlarged as to extend the volume of the book from two hundred and twelve to more than six hundred pages. A third edition was published in 1879, with further amendments. The author began the revision for this fourth edition in 1879, but was met with delays, and died before completing the work, which was left for his assistant and successor in his college pro- fessorship to finish. The contents consist of tables comparing the different thermo- metrical scales, with reductions from one to another; hygrometrical tables, with tables for the conversion of metrical hygrometric measures into others ; barometrical tables ; hypsometrical tables ; geographical meas- ures, in which means are given for reducing the measures of all countries from one to another ; meteorological corrections ; and " Miscellaneous Tables useful in Terrestrial Physics and Meteorology." The whole con- stitute a valuable reference book. The Ornithologist and Oologist, Vol. IX. 1S84. Pawtucket, II. I. : Frank B. Web- ster, publisher. Twelve Numbers. Pp. 152. Price, $1.50 a year; 15 cents a number. As is implied in its title, this is a maga- zine devoted to birds, their nests, and eggs. It is beautifully printed, and is sustained by a corps of competent and enthusiastic con- tributors, who record in it their daily, week- ly, monthly, yearly, or occasional observa- tions, on these the most attractive of man's companions on the earth. It is a pity that so many of them consider it an indispensa- ble preliminary to the observations to shoot the birds or steal their eggs. In the pres- ent state of science, these things, when they are done, are unnecessary in nine cases OHt LITERARY NOTICES. lV of ten. Except for the encouragement given to this practice, which is reprehensible, except when most sparingly and discriminat- ingly indulged in, we cordially recommend the " Ornithologist and Oologist " as a pub- lication that every lover of Nature will do well to have by his side. It also admits to its pages notes and observations on the kin- dred study of entomology. Our Bodies; or, How we live. By Albert F. Blaisdkll, M. D. Boston: Lee & Shepard ; New York : Charles F. Dilling- ham. Pp. 285. Price, 60 cents. This is a "Physiology for the Young," intended for an elementary text-book in the common schools. It aims to present clearly, concisely, and in a logical order, the most important facts about the build and health of our bodies. Prominence has been given to such facts of anatomy and physiology as are essential to a proper understanding of the laws of hygiene. Hence, special em- phasis has been laid upon the practical bear- ing of this branch of science upon daily life and personal health. As far as possible, each paragraph is complete in itself, and discusses a definite subject. The instruc- tions of the text are re-enforced by review and analytical chapters, and by a systematic series of practical and suggestive experi- ments, simple and not requiring expensive apparatus. Stories by American Authors. IX. New York : Charles Scribner's Sons. Pp. 180. Price, 50 cents. It was a happy thought to gather up into this series of volumes, convenient to hold in the hand or to put in the pocket, the fugitive short stories that have appeared from time to time in various publications ; many of them, perhaps, by authors whose works would never have been otherwise col- lected. To say nothing of their interest as stories, these works are of value — if we may judge from the present volume — as giving pictures of American character and life in various situations, with bright local coloring. One of the stories pictures a Vir- ginia neighborhood before the war ; another gives a piece of the life of a New England seaport village ; a third offers a view of a California village, with its political boss ; and another is a sailor's yarn, told in his own dialect.

Morse has published a re- view of the condition of zoology fifty years ago and to-day, in connection with the growth of the Essex Institute, which has just completed its first half-century. The institute has always kept true to its name. It has been wholly for the benefit and in the interests of the county of Essex, in every corporate town of which but one public meetings have been held, to the num- ber of two hundred in all ; while the enthu- siasm of its members has often led it be- yond the limits of the county and of the State, into, in all, some sixty -eight "out-cf- the-way places — little villages, cross-roads, and hamlets by the sea." To these places the society has induced the celebrated natu- ralists of the country to bring the results of their researches, and the latest and freshest fruits of science. Further evidence of its county character is found in the facts that its members are scattered over the county, and that it has aimed especially at forming a collection of the animals and plants of the county, and has such a collection, which is not excelled by any other of similar char- acter. When the Institute was founded, there was not a single text-book of zoology in our schools ; now, every high and classi- cal school has its classes in zoology and botany, and every college its special pro- fessor. Then there was not a single popu- lar periodical devoted to those sciences ; now there are a number of illustrated week- lies and monthlies with a large circulation, the earliest of them, the " American Natu- ralist," having been founded under the au- spices of the Institute ; and even the news- papers keep pace with the progress of science, and publish special articles on sci- entific matters of interest. Then, the sci- ence of archaeology was not born ; now it is ' the most vigorous and aggressive of the sciences," and one of the Institute's men, Mr. Putnam, " is, for the first time, teach- ing the country the proper and only way of exploring the mysterious mounds of the West." The little society of a few men and a library of a hundred volumes has grown to be a powerful body of three hun- dred and forty members, with a library of thirty-eight thousand volumes. POPULAR MISCELLANY. »33 Why Wool felts.— The cause of the felt- ing properties of wool is generally attrib- uted to serratures on the surface of the fibers, which are supposed, when driven into the closest possible contact, to hook into one another, and so to hold together by what might be called a " beggar's-lice grapple." The validity of this theory was called into question by two gentlemen of Hartford Captain George R. Case, a microscopist, and Mr. Joseph Dawson, a woolen manufacturer. These gentlemen, obtaining samples of wool of different grades, subjected them to vari- ous manipulations, and found: 1. That a single fiber of wool, when manipulated by itself in a lubricant of soap, has no fulling property, but rather a tendency to lengthen the fiber ; 2. That a number of fibers placed side by side, just as they grew on the sheep, and with simply tension enough to take out the kinks, when manipulated with a lubri- cant of soap, have no felting property, 3. That fibers similarly treated, but with the roots and tips alternating, have no fulling or felting property, and no power of adhe- sion ; but, 4. That a number of fibers placed side by side, with the tips all one way or with the roots and tips alternating, without any tension, have fulling properties ; and, 5. That fine-carded wool, taken from a sec- ond breaker, with the fibers thoroughly mixed, has great fulling properties when properly manipulated. A sample of negro's hair of suitable length, which was found by microscopical examination comparatively free from serratures but slightly spiral in structure, manipulated in the same manner as the wool had been, was formed into a " well-felted sample of cloth." These and other experiments satisfied the authors that the fulling properties of wool or any other fibers were in proportion to the number of waves, curls, or kinks, and their degree of fineness, and that the serratures, per se, have little to do with the matter, excepting pos- sibly that which may be due to friction. " To the question, What is the cause of the fulling or felting of wool ? the simplest an- swer possible is, it is the looping and in- terlooping, locking and interlocking of the fibers until they become inextricably en- tangled, but by interlooping and interlock- ing, and not upon the beggar's-lice prin- ciple." Spade-Foot Toads —Dr. Charles C. Ab- bott contributes to the " American Natural- ist " a study of the hermit spade-foot toad {Scaphiophis Holbrooki), a rare animal, whose custom it seems to be to appear unexpect- edly in numbers, and, after a few days, sud- denly to disappear. Its name is derived from its long, horny index-toe, which may well be characterized as a spade, for it digs with it rapidly into the ground ; and its voice, immense for so small an animal, is like a steam-whistle. The spade-foots first visited Dr. Abbott's field of observation in May, 1874, 6tayed a few days, and were gone. Their next visit, ten years having passed without a single specimen being seen or heard, was April 10, 1884, in the same spot, a sink-hole in a dry upland field near Trenton, N. J. They remained till the 15th, when the weather became cooler and they vanished. Again they came, June 26th, after a rain-storm that flooded the sink-hole, and were found sitting on the grass-tufts and swimming in the pond by the hundred, all uttering their shrill, ear-piercing groans, through the day and night; but on the morning of the 28th all were gone. During this brief visit the frogs spawned, and the eggs were found attached to blades of grass and slender twigs. In about a week, those of them which were not destroyed by the retiring of the water were hatched out into tadpoles very much like other tadpoles. As they grew, about five per cent of the num- ber failed to develop as rapidly as the others. These " retarded " tadpoles were voracious cannibals, preying upon their fel- lows, now become " hoppers " and minia- tures of the adult spade-foots, so extensively that it was necessary to protect them to save any. In due time, the water was re- moved from the aquarium, and earth put in its place to about an inch in depth. " Upon this the young spade-foots were placed, and in less than one minute many had com- menced digging little burrows, into which they disappeared as the excavations deep- ened. ... In twenty minutes all but two of forty-four specimens were below the sur- face." A few individuals remained in the sink-holes as the water dried up into pud- dles ; but Dr. Abbott having neglected them, under the supposition that they would bur- row where they were, for ten days, could find 134 THE POPULAR SCIENCE MONTHLY. no trace of them upon an exhaustive search. He concludes that the animals must wander farther from their breeding-grounds than is supposed, or else must dig far deeper into the earth than to six or eight inches, as stated by Holbrook and De Kay. Effect of Earthquakes on Buildings. — Mr. John Milne, of Tokio, Japan, has pub- lished some observations of the effects of earthquakes on buildings. In regard to the relative security of buildings on low and on high ground there is no universal rule, but each small area in an earthquake-region has its peculiarities. Theory indicates that soft, marshy ground is safer, because it will act as a buffer between the shock and the build- ing ; and the Temple of Diana, at Ephesus, was located with reference to this point. But experience at Tokio and Manila has shown repeatedly that there is very little, if anything, in it ; and hard, rocky strata, where the amplitude of motion is small, but the period quick as compared with the mo- tion in the inelastic material of the plains, proved the better foundation in Jamaica in 1692, and at Lisbon in 1755. Places to be avoided are the edges of cliffs, scarps, and cuttings. Europeans fasten the foundations of their buildings firmly in the ground, and their houses are much shaken. The Japa- nese put their structures loosely on top of stones or bowlders, and they escape seri- ous disturbance. Europeans and Americans build iron-bound houses to resist earth- quakes, and they resist them, though they get badly shaken, as a steel box would be ; but they are very expensive. The Japanese and the people of the west coast of South America build a kind of wicker - basket house — a frame house with a light roof, which lives through the earthquake like "a reed shaken by the wind." The stability of such houses depends upon their not being firmly attached to the earth, and their nu- merous joints admit considerable yielding, so that the earthquake-wave passes through them before they begin to show its visible effects. A cheap aseismic house would be a low frame building supported by a num- ber of slightly concave surfaces resting on segments of stone or metal spheres in con- nection with the ground. Chimneys should be given a play-space around them, and not be in contact with the roof ; else, since the vibrational periods of the chimney and the roof never correspond, clashes will occur between them, and a shock and overthrow result. The pitch of the roof should not be great, or the tiles or slates will be shot off ; and the upper parts of all buildings should be as light as is consistent with strength. Suggestions in School-keeping. — Mrs. H. F. Wilson, in a paper read before the Educational Association of Alabama, tells how in her school she eschewed the system of marks and statistical reports as pernicious and false, and imposed as the one rule to govern the whole school, " Do right " ; and, as the real goal to be reached, excellence in everything. Incorrect sentences heard by any pupil are reported in a blunder-box, to be corrected by the school. Once a week, half an hour is devoted to the recitation of facts, drawn from the public press and other sources. Half of every holiday is given to microscopic, stereoscopic, or other instructive exhibitions. In connection with the teaching of music, information is col- lected concerning the old masters of music. Physical culture is attended to, and dancing is cultivated as an element of it. In this work the teacher finds infinite variety and enjoyment, and has been " filled with amaze- ment and enthusiasm at the immense amount of work pupils did unbidden, hunting over cyclopaedias and books of reference for in- formation when the text-book was obscure or inadequate." Source of Atmospheric Electricity. — The source of atmospheric electricity has never yet been satisfactorily indicated, al- though various theories have been suggested to account for it. It has been attributed to aerial friction, to combustion or oxidation, to evaporation, and to condensation, to in- ductive or conductive effects of the earth's electricity, to convection currents, to electri- fied corpuscles coming from the sun, to solar radiation, to the friction of aqueous vapor against dry air, to capillary surface-tension of water, to the production of hail, etc. Professor Tait suggests that the mere con- tact of the particles of vapor with the air may suffice to produce the exceedingly small potential requisite to start the effects. He POPULAR MISCELLANY. »35 has not had an opportunity to investigate his hypothesis, but he makes a few state. ments that illustrate how apparently small this potential may be. " To raise a single pound of water," he says, " in the form of vapor from the sea or from moist ground, requires an amount of work equal to that of a horse for about half an hour. This is given out again, in the form of heat, by the vapor when it condenses ; and the pound of water, falling as rain, would cover a square foot of ground to the depth of rather less than one fifth of an inch. Thus, a fifth of an inch of rain represents a horse-power for half an hour on every square foot ; or on a square mile, about a million horse-power for fourteen hours. A million horses would barely have standing-room on a square mile. Considerations like this show that we can account for the most violent hurricanes by the energy set free by the mere condensa- tion of vapor required for the concomitant rain. Now, the modern kinetic theory of gases shows that the particles of water- vapor are so small that there are somewhere about three hundred millions of millions of them in a single cubic inch of saturated steam at ordinary atmospheric pressure. This corresponds to l/ieoo or so of a cubic inch of water — i. e., to about an average rain-drop. But if each of the vapor par- ticles had been by any cause electrified to one and the same potential, and all could be made to unite, the potential of the rain-drop formed from them would be fifty million million times greater. Thus it appears that if there be any cause which would give each particle of vapor an electric potential, even if that potential were far smaller than any that can be indicated by our most delicate electrometers, the aggregation of those par- ticles into rain-drops would easily explain the charge of the most formidable thunder- cloud." How an Iron-Ore Bed was formed. — Professor James P. Kimball, of Lehigh University, has published in a single pam- phlet two papers on the iron-ores of the Juragua Hills, of the province of Santiago, Cuba, beds of a hematite or specular ore, which appears to be largely the result of the weathering of the highly basic rock which gives the geological character of the formation. These rocks, the eruptive ma- terial which gave origin to the iron-ore, consisted of proto-silicates, or silica com- bined with the protoxide bases, iron, lime, and magnesia, and with alumina. Under its new conditions at and near the surface, with access to oxygen in the atmosphere, circu- lating waters, etc., the protoxide of iron became rapidly further oxidized into ferric or sesquioxide, which is a comparatively stable product under conditions prevailing at the surface. The oxidation of the fer- rous to ferric oxide is attended with more or less complete dismemberment of the eruptive rock, little by little. Silica origi- nally combined with the ferrous oxide is isolated as silica. Silicates of lime, mag- nesia, and alumina form new aggregates among themselves. Soluble matter as fast as isolated enters into solution in circulat- ing waters, and is thus at hand to assist in the work of weathering. This work of alteration has gone on until a complete change has been wrought not only in the composition but also in the arrangement of the original eruptive rock. By the law of molecular attraction a process of concentra- tion has gone on simultaneously with the process of weathering decay. Homogene- ous material, such as ferric oxide, was col- lected by itself to a degree far greater than the other earthy residues, because, in the process of conversion from ferrous to ferric oxide, it has been in solution, and so in cir- culation, and has hence become finally de- posited under long - prevailing conditions of uniform circulation. The process here briefly followed out has gone on just below the surface, within the range of the circu- lating waters. The same action immediately at the surface is followed by waste or diffu- sion of the products of alteration. In the present case, the best of the ore-bodies are mainly, if not indeed wholly, replacements of coralline limestone. Jnles Verne as a Scientific Authority. — The " Revue Scientifique " discusses a curi- ous question in giving its estimate of the value of Jules Verne as a scientific writer. It considers the judgment, which many of us are ready to give, that such science as is inserted into the framework of a romance is worse than no science at all, as too severe. 136 THE POPULAR SCIENCE MONTHLY. " Does any one believe seriously that a can- non-ball can be shot from the earth to the moon ? But what harm is there ill letting a child entertain a fancy of the kind for a few hours ? He amuses himself with it, and, while he is amused, he learns, without conscious effort, that the moon revolves around the earth, and the earth around the sun, aud that there are forces of gravitation and universal attraction, etc. . . . The false idea does no harm, for nothing is built upon it. ... I venture to say that it is advan- tageous to inspire children with the love of hazardous adventures, and the taste for the unknown that they find in all the romances of Jules Verne. They will encounter real difficulties soon enough to be discouraged from them earlier than they need to be. Not to see the difficulties is sometimes a good way to triumph over them. We have all grown timid and hesitating, and it is not a bad thing for us to be roused up to ardor in chimerical enterprises, in which the power of science is exhibited to us in the service of an energetic will. It is, perhaps, on this account, as much as for the amusement they give us, that we avow a strong liking for all of M. Verne's works. We might, if it were worth while, defend M. Verne on other considerations. When an idea enters the mind of a child, what matter is it how it gets there ? Whether it be in a romance, or in a lesson, or in a text-book, or in a familiar conversation, makes but little difference, so the result is acquired. To tell a fourteen- year-old boy that the diamond is crystallized carbon, and that fruitless efforts have been made to produce it artificially, is all very well, but will he remember it? Are these abstract facts interesting enough to stay? Possibly; but the contrary is probable. When you interest a child by relating to him the adventures of Cyprian, as he puts earth and charcoal into a crucible, and tries to crystallize it into a diamond, the scien- tific fact will not be forgotten ; and some day Cyprian will retire into the background, while the physical fact will be a permanent acquisition, which he will owe to this new mnemonic agency. It is more than mne- monics. While M. Verne entertains us with adventures, and fastens scientific facts upon us, he also gives us a taste for sci- ence. With him it is a goodly personage, smiling, affable, pleasant, greeting all who come." Crickets and u Hair-Snakes." — The so- called horse - hair snake, as is known to naturalists, is a parasite of the cricket, which only becomes active under water. Dr. H. C. McCook recently read a statement before the Academy of Natural Sciences of Philadelphia which indicates that the crick- ets are aware of the peculiarity of their para- sites, and take advantage of it to get rid of them. A lady having moved into a house which was a harbor for crickets, was troub- led by frequently finding the hair-snakes in her water-pails, a short time after the water had been brought into the house. She sat down to watch how they came there. In a short time she saw " a particularly pleth- oric cricket " mount upon the edge of the pail, and, after some uneasy movements, bring the tip of the abdomen just beneath the water, and, with a few violent throes, expel a black mass, which fell slowly through the water, and, before it reached the bot- tom, resolved itself into one of the worms. The cricket seemed much exhausted by the operation. Toxic Effects of Smoking.— Dr. Zulinski, of Warsaw, has made some experiments upon the effects of tobacco-smoke, which he determined to be a distinct poison, even in small doses. Its action on men is very slight when it is not inhaled in large quan- tities, but it soon becomes powerful in those who contract the habit of " swallowing the smoke." The toxical property is not due exclusively to the nicotine, but the smoke, even when disengaged from nicotine, con- tains a second toxical principle, called so- lanine, besides carbonic oxide and hydro- cyanic acid. The effects produced by smok- ing depend upon the nature of the tobacco and the way in which it is smoked. The cigar-smoker absorbs more poison than the cigarette-smoker, and he than the person who smokes a pipe ; while the one who uses a medium, by which the smoke is conducted through water, reduces the deleterious effects to a minimum. As a rule, the light-colored tobaccos are supposed to be the mildest, but they are sometimes artificially uncolored by chemicals, the presence of which is danger- POPULAR MISCELLANY. 137 cms. Tobaccos are also generally adulter- ated, and, if the adulterating matter be woody, the smoke will be of high tempera- ture, and liable to cause inflammation of the tongue. Antipathies^ — Some strange cases of an- tipathy are recorded in the lives of eminent men. Erasmus was made feverish by the smell of fish. Ambroise Parr had a patient who would faint at the sight of an eel, and another who was convulsed on seeing a carp. Gardan was disgusted at the sight of eggs. A king of Poland and a secretary of France bled at the nose when offered ap- ples. A huntsman in Hanover, who would attack a wild-boar valiantly, ran away or fainted whenever roast pig was presented to his view. A person is told of who fainted whenever he saw a rose, and similar stories are told of antipathies to lilies and honey. Tycho Brahe abhorred foxes, Henry III. of France cats, mice, spiders, etc., and Mar- shal d'Albret pigs. There was " once upon a time " a lady who could not endure the sight of silk or satin. The man who would faint whenever he heard a servant sweep- ing is not so much of a stranger, and the one who was similarly affected by the sound of a bagpipe invites universal sympathy. Boyle was overcome at hearing the splash- ing of water. Coinage Alloys. — According to Professor W. Chandler Roberts, of the Royal Mint, the term alloy is usually applied in ordinary language to the mass formed by mixing a base metal with a precious one, while in sci- entific language it indicates the base metal which is added. Alloys are used in prefer- ence to pure precious metals for various reasons, chief among which is the fact that they are harder and more durable. The fact that their substitution for pure gold or silver may be a valuable source of revenue is a less commendable reason, but has not been without force. When a base metal is to be chosen for mixture with a precious one, it should be borne in mind that the re- sulting alloy must have the qualities of good color, ductility, and freedom from brittlc- ness. Silver forms a very ductile alloy with gold, but lowers the color, while copper forms a durable as well as a ductile alloy and heightens the color. A triple alloy of gold, silver, and copper may be made of delicate tints ; but it is difficult to assay and causes complications in the keeping of the accounts, and for those reasons the simple copper alloy is now almost universally used. At the mint, the qualities sought as most desirable in an alloy are: 1. Ductility; 2. Durability ; and, 3. Uniformity of composi- tion. The alloy is, besides, expected to be sonorous, or to impart the true " ring " to the coins struck from it, and to possess the degree of viscosity which will enable it to flow under pressure into all the fine lines of an engraved die, while at the same time the metal must be rigid enough to retain its impression when submitted to rough usage. A great variety of alloys have been used for coinage in the world's history, from pure precious metal down to base metal with only a trace of precious metal in it. Those now in use arc not very numerous. The fine- ness of alloys of silver is computed with reference to the troy pound. The compu- tation in the case of gold alloys is based on the singular " carat " system, the name of which is probably derived from the Kepdriov, a small Greek weight. This has within two years given way at the British Mint to a decimal system. Making Champagne.— The making of champagne is a process requiring extreme care and attention at every stage for at least two years. The grapes are picked with especial pains to keep any of them from falling or receiving bruises. Only the juice of the first pressing is made into high-class wine, and the quantity of this that shall be drawn is regulated by weight. Four hun- dred kilogrammes arc allowed for every forty gallons of wine, and when the desired quantity has been obtained the pressing is stopped. The protruding edges of the mass which have escaped the heavier pressure are cut off and subjected to a second pressure, the juice from which is called the first tallh. A thirdj pressure gives the second faille, and a fourth the redeche, juices that are considered fit only for the workmen. When the scum has risen in the wine-tubs it is taken off, and the casks are filled and fumigated with sulphur and put away, not quite full, in the cellar, for fermentation. i38 THE POPULAR SCIENCE MONTHLY The wine is racked off into other casks when the fermentation has subsided, and becomes quite clear by the time the December frosts set in. It is then mixed, by bringing to- gether thirty or forty casks of the same growth, and blended. Tannin is added, to neutralize grease and deposits, and as much alcohol as is required. At a later stage a masque or deposit forms on the side of the bottle, the removal of which requires much care and skill and manipulation for several weeks. Afterward a sirup of sugar and alcohol is added, in proportions varying ac- cording to the country to which the wine is to be sent. Finally, the bottles arc corked, wired, and set on end. Changes in the Color of the Hair. — Cases of changes in the color of hair other than to gray are not uncommon. Workers in cobalt-mines and indigo-works sometimes have their hair turned blue, and workers in copper green, by deposition of coloring-mat- ter upon it. This, however, is only a super- ficial coloring, and can be washed off. Pren- tiss records a case of a patient to whom muriate of pilocarpine was administered hypodermically whose hair was changed from light blonde to nearly jet-black, and his eyes from light blue to dark blue. These changes were due to increase of nor- mal pigment. Hauptmann relates a case of a body exhumed twenty years after burial, the hair on which had changed from dark brown to red. Leonard cites a case in which, after death, red hair was changed to gray within thirty hours. Other cases have been mentioned in which the color of the hair has been variously changed in conse- quence of disease. Decline of Mnssnlman Indnstries. — Ac- cording to a letter in the " Allgemeine Zei- tung," art and industry are in a lower stage in Algeria than in any other Mohammedan country, and their progressive decline is per- ceptible there from day to day. Persons may be seen walking in the streets of Al- giers, dressed in Moorish or Arabian cos- tumes, every piece of which is of European origin. Many branches of industry are ex- tinct, others are nearly so, and all show un- mistakable signs of decay. Many articles of European production are much cheaper than Mohammedan fabrics of the same kind, and are preferred for that reason ; and many which at the first glance seem to be Mo- hammedan are in fact European imitations. Most of the really Mohammedan articles which are found, such as carpets, cloths, and table-wares, are not Algerian, but of Moroc- can or Syrian manufacture. Arms are not made, for the wearing of them is forbidden by the French Government ; but the Kabyles make a kind of iron knife, which can hardly be called a weapon. The only native in- dustry still flourishing in the city of Algiers appears to be shoe-making, and this is be- cause the Algerine men refuse to wear Eu- ropean shoes ; but the women wear shoes of the prevailing fashion, with Louis XIV. heels. The cause of the depression of Mo- hammedan industry is the pressure of Euro- pean population and influence, which has been attended with a corresponding diminu- tion of the Turkish element. Aryan Origins.— Professor K. Penka, of Vienna, has recently published a work on " Aryan Origins," in which, according to Professor A. II. Sayce, an eminent linguist, he sets out with " the incontrovertible but hitherto neglected doctrine that language alone will not interpret for us the former history of our race. Without the aid of anthropology, it is not only useless, but misleading. The theories built on the as- sumption that language and race are inter- changeable terms, have introduced nothing but confusion into science, and have even left their scar on the politics of the day. It is only the skull in the hands of the anthro- pologist which can teach him the relation- ship of a people ; the language they speak, or may have spoken, will of itself tell him but little." Professor 0. Schrader has pub- lished, at Jena, a work regarding the Indo- Germanic race from the linguistic side, " in which," says Professor Sayce again, " for the first time a thoroughly critical method has been employed in determining the char- acter and condition of primitive Aryan so- ciety by means of the records of speech ; and the results are very different indeed from the idyllic picture of that civilized community to which Pietet and other writ- ers have accustomed us. The early Aryan comes before us as a coarse and uncivilized POPULAR MISCELLANY. *39 nomad, unacquainted with the use of met- als, and protecting himself with the skins of wild beasts from the inclemencies of the climate." What his society was like, Pro- fessor Schrader thinks may be gathered from the remains left by the " pile-villagers " of the Swiss lakes, whom he regards as Ar- yans. Both Professor Penka and Profess- or Schrader express the belief that Europe, and not Asia, was the original home of the Aryan family. Penka considers the start- ing-point of Aryan emigration to have been Scandinavia, while Schrader suggests the northeastern lands of Europe generally as the most probable locality. The evidence, according to Professor Sayce, is now tend- ing to show that the districts in the neigh- borhood of the Baltic were those where the race or races who spoke the Aryan lan- guages originally dwelt, and that the Aryan invaders of Northwestern India were only a late and distant offshoot of the primitive stock who were speedily absorbed into the earlier population of the country as they advanced southward. A Highway in the Himalayas. — One of the native explorers of the Himalayan re- gions of India lying beyond the British boundary, says Sir J. H. Lefroy, in his Brit- ish Association address, " describes a por- tion of his track at the back of Mount Everest as having been carried for a third of a mile along the face of a precipice at the height of fifteen hundred feet above the Bhotia-kosi River upon iron pegs let into the face of the rock, the path being formed by bars of iron and slabs of stone stretching from peg to peg, in no place more than eighteen inches and often not more than nine inches wide. Nevertheless, this path is constantly used by men carrying burdens." Currency of the Cannibal Isiands. — Mr. Walter Coote has described some curious monevs of the New Hebrides and the Solo- mon Islands. On one of the islands he no- ticed a neatly-kept house, which he was told was the money-house. Entering it, he found a number of mats hanging from the roof, beneath which a fire was constantly kept up, under the effect of which they became covered with a black, glistening coating and adorned with festoons of soot. It was a man's business to keep the fire always burning, and so low as not to scorch the mats. A well-colored mat is worth about as much as a well-grown, vigorous boar. This is the strangest of all kinds of money, for it must never be taken from the money- house, even when the title in it is trans- ferred from one owner to another. The inhabitants of Santa Cruz Island use for money rope-ends, about an inch thick, and ornamented with scarlet feathers, which are worn about the waist. The traveler could not obtain new coins of this kind, but found them current everywhere. The specimens he bought were already old, and the feath- ers grown dingy. The money of the Solo- mon Islands consists of neatly-worked pieces of shell of about the size of our shirt-but- tons. They are strung on strings about four yards long, and are distinguished un- der the names of red and white money. Dog-teeth are of higher value, and compar- able to our gold coins. They are usually worn on a string around the neck. Mr. Coote saw a necklace of this kind that was valued at about a hundred dollars. Marble rings are also worn on the breast for orna- ments, and as valuable money. The cur- rency-table of these islands would be about as follows : 10 cocoanuts=l string of white-money. 10 strings of white-money = 1 string of red-money, or 1 dog-tooth. 10 strings of red-money = 1 isa, or 50 dolphins' teeth. 10 isa = 1 fine woman. 1 bahika, or marble ring = 1 head with the head-antlers, or 1 good hog, or 1 useful young man. Theory of Lubricants. — In a British As- sociation paper on the theory of lubricants, Professor Osborne Reynolds referred to some experiments by Mr. Tower, which showed that, when the rotating journal with its box was immersed in a bath of the lu- bricant, the resistance was not more than one tenth of its value in ordinary oiling, and that the journal was less likely to heat at higher than at lower speed ; and that if, after running the journal for some time in one direction, a reversal was made, great heating would result. This was to be ex- 140 THE POPULAR SCIENCE MONTHLY. pected, in the light of an observation made by Professor Reynolds, that there must re- sult a difference of pressure on the two sides of the vertical line through the center of gravity in the thin space between the box and the journal — the maximum being on one side or the other, according as the rotation is one way or the other ; for, un- doubtedly, the box and journal became adapted to each other for a certain direc- tion of running, and when a reversal was made some time would elapse before a re- adaptation would be completed. This would explain why a new journal and box would always heat on first being run, however per- fect they might be. Deaths by Poisoning. — According to the English Registrar-General's reports, deaths by poisoning occur with alarming frequency in the ordinary course of events. In 1881, 569 deaths were recorded in England alone from this cause; in 1882, 599, or one in every 863 of the total deaths registered. Fully two fifths of the cases in the latter year were classified under the heading " ac- cident and negligence " ; the rest, 288, were suicides. Of the deaths through accident or negligence, 85 were occasioned by opium, laudanum, and morphia ; 18 by lead com- pounds ; 34 by the four stronger acids — hydrochloric, nitric, sulphuric, and carbolic ; 14 by chloral ; 11 by phosphorus ; nine by arsenic ; six by chlorodyne ; four by chloro- form ; and four by soothing -sirup. How came the victims of these poisons to take them accidentally in fatal doses ? The medi- cal reports on the subject trace the mistakes to two principal causes — the giving or tak- ing of overdoses of certain remedies con- taining poisons, and the substitution of one bottle or substance for another, as where bottles of all kinds of things are piled to- gether in the cupboard, and, in the nervous- ness of haste or in carelessness, the wrong one is taken. The remedies for these dan- gers ought to be obvious. One is, never to give an infant an opiate or other powerful soothing remedy without first obtaining the sanction of a doctor. Another is, that no patient taking powerful remedies should be permitted, or 6hould permit himself, to measure or repeat the dose himself. A third is, never to place bottles or packets containing poison alongside of or near any- thing that is to be taken internally. Fourth, never to put any poison into bottles, jugs, or cups which children or any other persons are apt to associate in their minds with sub- stances not in themselves dangerous. The last remedy is sovereign. It is, not to keep strong remedies on hand. Relation of Color and Flavor in Fruits and Vegetables. — Mr. Emmett S. Goff re- cords in the " American Naturalist " some investigations he has made to determine whether there may not be a law of relation between the color and flavor in fruits and vegetables. He was led to his experiments by the observation that in several fruits and vegetables, such as onions, currants, to- matoes, and raspberries, a white or light- colored flesh is accompanied by a milder and more delicate flavor than exists in other va- rieties of the same fruit or vegetable hav- ing a dark-colored flesh ; also that seme vegetables are " blanched " to give them a more delicate flavor. The usual aim in im- proving the qualities of fruits and vegeta- bles is to intensify the desirable qualities and eliminate the undesirable ones. It is evident, therefore, Mr. Goff says, that, if the color of the flesh has a direct relation to its flavor and tenderness, we have a valuable index in the work of selection. If by whit- ening the flesh of a fruit we can eliminate acid and solidity, or if by darkening the flesh of another fruit, already too tender and in- sipid, in the same way, we can heighten its characteristic flavor and increase its firm- ness, we have gained a new faculty in mak- ing the products of Nature subservient to our wants. Mr. Goff supports his view by the citation of a number of fruits and vege- tables of peculiar qualities, and quotes de- scriptions by various authors, which appear to be in agreement with it. The Harp-Seal in the St. Lawrence River. — It has been long known that the harp-seal (Phoca Qroerdandica) was accus- tomed to visit the Gulf of St. Lawrence for bringing forth its young ; but Dr. C. nart Merriam has collected evidence that its ex- istence in that river is far more general and fixed than had been supposed. Mr. Napo- leon A. Comeau, who lives near the point POPULAR MISCELLANY 141 of the expansion of the river into the gulf, says that this species is the most abundant of all the seals of that locality, and roves up and down the St. Lawrence in its migra- tions iu immense numbers ; and he adds that it is tolerably common as far up as the Saguenay. From the information furnished by Mr. Comeau and from other data, it ap- pears to Dr. Merriam that the harp-seal is a permanent resident in the St. Lawrence ; that it spends the summer wandering about, some- times singly or in small schools, sometimes in larjre herds ; that it ascends the river at least as far as the Saguenay, and is common between Mille Vasches and Manicouagan ; that it frequents with considerable regular- ity particular shores and estuaries to feed on the small fish that congregate there at certain states of the tide ; that it works down the river early in the winter, and is particu- larly abundant about Point des Monts in December, January, and the early part of February ; that it then passes farther down to whelp on the heavy ice in the gulf ; that its young are born during the latter part of February or early March ; that, as soon as the young are able to shift for themselves, the parents at once return, passing Point des Monts in great numbers on their way up the river. Alleged Nerve-exciting Properties of American Air. — A correspondent of the Lon- don " Times " notices as a fact coming within his own personal experience the effect of the American air, particularly in New York, in exciting nervous sensibility. It is partly an effect of dryness, partly elec- trical, as is witnessed by the power some- times observed of lighting a gas-jet with the electric spark developed by shuffling rapidly over the carpet. It is observed also in the greater intensity of the effect of spir- ituous liquors in this country than in Eu- rope. ' It is partly local, for it is more marked in New York than in any ether place. It seems to be evolving a new type of mind, and ultimately possibly a new phys- ical type ; and the American appears to be becoming a more nervous and more spirited man. Hence, we have peculiarities in our statistics of insanity; our army of tramps — " individuals of all classes, though mainly of the poorer, who can not endure the drive and strain necessary to keep up with their fellows, and whose inertia triumphs " — and our cranks— •" people who carry eccentricity almost to iusanity, but are recognized as responsible persons." After noticing an increasing development of insanity among our native-born population, the writer men- tions two questions that suggest themselves : " Are we becoming a nation of madmen," or " are we developing a specialized race from those who can endure the pressure, and who by the survival of the fittest will form the future American stock, while the feeble in- tellectual natures will become tramps and lunatics ? " The Weather and Health.— -Dr. J. W. Tripe read a paper at the Meteorological Con- ference, held in connection with the London Health Exhibition, on "The Relations of Meteorological Phenomena to Health." It is only recently that systematic observations have made the collation of knowledge on this subject possible. Ordinary variations of the barometer at ordinary elevations pro- duce but little effect on health. At consid- erable elevations disagreeable feelings fol- low the diminished pressure. Nevertheless, consumptive and other invalids have experi- enced relief at mountain-stations ; but this was because the reduced temperature, with the total change in the habits of life, more than compensated for the effects of the lessened pressure. In residences a sudden diminution of atmospheric pressure is likely to be attended with an escape of ground-air from the soil, and thereby to cause injury to health. Changes of temperature when rapid are liable to cause derangements in either direction ; otherwise man can with precautions endure a range of about 200° Fahr. without serious injury. Hot climates, however, eventually, unless habits are care- fully adjusted to them, sap the foundations of life among Europeans. The direct influ- ence of rain on man is not very marked in temperate regions, except by giving moist- ure to the air by evaporation from the ground and from vegetable life, and by al- tering the level of ground- water. Consider- able and sudden fluctuations in the level of the ground- water generally cause ill health, and if such water stands at less than five feet below the surface it is dangerous. Vary- 142 THE POPULAR SCIENCE MONTHLY. ing amounts of moisture in the air materi- ally affect health and comfort. Moist air is a better conductor of heat than dry air, hence we feel more chill in thaws than during crisp, cold weather. Fogs are in- jurious, net only on account of the vapors they contain, but because the air is satu- rated with moisture at a low temperature. Variations in temperature and pressure ex- ert a considerable influence on the circula- tion of air contained in the soil (ground-air), and this frequently contains that which it is not well to breathe. Winds affect health directly by promoting evaporation from the skin and abstracting heat from the body, and indirectly by their influence on the temperature and pressure of the air. Scarlet fever prevails most when the mean temperature is between 45° and 57° Fahr. Diseases of the lungs are fatal in proportion to the lowness of the temperature and the presence of excess of moisture and fog. Relations appear to exist between a high summer temperature and mortality from di- arrhoea. The relations between the weather and disease are not always uniform, for a discordance has been observed in the curves for whooping-cough, typhoid fever, and scar- let fever, between London and New York, and in diarrhoea between London and India. Better information is needed on this sub- ject. Speetro-pbotomotric Study of Pigments. —Edward L. Nichols, Ph. D., in a paper read at the last meeting of the American Association on " A Spectro - photometric Study of Pigments," finds that the spectro- scope shows that pigments can not be con- sidered even in the roughest approximation as reflecting monochromatic licrht, but that they are more nearly related to white. Hence, " the attempt to express the hue of non-luminous bodies by comparison with isolated spectral tints is founded upon a false conception of the nature of the light which they reflect. To determine the hue of a pigment from the analysis of the light it reflects is a problem in physiological op- tics, the solution of which varies with the character of the observer's eye. The three primary color-curves of the eye must be determined, and the total intensity of each wave-length of the spectrum of the pigment must be divided in the proportions indicated by the color-curves into three components — red, green, and violet. Summing up each of these components for the entire spec- trum, we obtain an expression for the hue in terms of the three color-sensations of which it is the resultant. In default of this method, which is difficult of execution, the curves themselves are an expression of the hue, the only requisite for the interpre- tation of which is practice in associating the sensation of color produced by pigments with the form of curve representing them." The Manufacture and Applications of Iridiin 1. — The manufacture of articles from iridium has recently assumed considerable importance through the discovery of practi- cable methods for making the metal. Irid- ium is obtained, in Russia and California, as a by-product in the working of the ores of platinum and gold, and is found only in the condition of grains, not larger than grains of rice, or of a fine powder, and oft- en alloyed with platinum or osmium. It is one of the hardest substances known, being in that respect nearly the peer of the ruby, is not readily or permanently acted upon by oxygen, and is soluble in no single acid, and only slightly soluble in aqua rcgia. Its principal use hitherto has been for the point- ing of gold pens, for which purpose the grains had to be taken as they were found, and soldered on without working over. The discovery of the process for working iridium is due to two gentlemen of Cincinnati, Mr. John Holland, a gold-pen manufacturer, who found that it could be melted with phosphorus ; and Mr. W. L. Dudley, who devised a method for afterward eliminat- ing the phosphorus. Mr. Holland, seeking larger pieces of iridium than could be found in Nature, discovered, after many experiments, that by heating it to a white heat and adding phosphorus, with a few minutes more of heating, he could obtain a perfect fusion, and could pour out the molten metal and get a casting of it. The product proved nearly as hard as the nat- ural grains of iridium, and to have nearly all the properties of the metal itself, but, con- taining from 7"52 to 7*74 per cent of phos- phorus, was liable to fusion, and could not therefore be used for purposes, as in elec- NOTES. H3 trical apparatus, where it would have to withstand a white heat. Mr. Dudley under- took the removal of the phosphorus, and found that this could be effected perfectly by heating the metal with lime in an elec- tric furnace. The manufactured metal will then resist as much heat without fusion as the native metal. Iridium is sawed by a copper disk between four inches and eight inches in diameter, making twenty-five hun- dred revolutions a minute, and dipping into a bath of cotton-seed oil and corundum or diamond-dust. Many new uses are open- ing for it since it has been possible to melt and cast it. It is used for draw-plates, to replace the ruby plate, in the manufacture of gold and silver wire; for knife-edges for scales and balances ; for tipping hypo- dermic needles; for the negative poles of arc-lamps; and for many other purposes. One of the most important applications is for the contact-points of telegraphic instru- ments. These points outlive many platinum contacts, and do not oxidize or stick. Mr. Dudley is making experiments, with a fair promise of reaching commercial success, in the electric deposition of iridium. The Chaldean Lunar Cycle. — M. Oppert recently read a paper before the Academy of Inscriptions and Belles-Lettres on an As- syrian inscription concerning lunar cycles. More than twenty years ago he discovered in the inscriptions of King Sargon allusions to a great lunar cycle one of the revolutions of which terminated in the year b. c. 712. He was afterward convinced that this cycle was the period of 1805 years, after which the series of lunar eclipses recur in the same order. The knowledge of this period sup- poses continuous astronomical observations among the Chaldeans already of many cent- uries' duration. They began the calcula- tion of the period from the year 11,542 be- fore our era. This is also the year in which the Sothiac periods (of the Egyptians) of 1460 years begin, one of which ended b. c. 139. These two cycles of 1460 years and 1805 years play an important part in the chronological computations of the ancient East. Twelve of each of them form re- spectively 17,520 and 21,660 years, or 292 and 561 sixties of years, numbers which oc- cur in the Bible, according, to M. Oppert, to express the length of time between the Flood and the birth of Abraham, and from the birth of Abraham to the end of the history in Genesis. NOTES. Thirty years ago pines were planted in the Sologne, a tract of waste land near Blois, France. Fifteen years afterward, as the pines were cut away, oaks sprang up spon- taneously to take their places, thus tending to restore what history tells was the ancient vegetation of the country. M. Emile Hau- sen-Blangstcd states, in illustration of the struggle for existence among trees, that the pine is dislodging the larch in the Grisons, while there and in the Jura the beech pre- vails over both. In Switzerland generally the beech gains the place of the oak, fir, and birch, and in Prussia the pine encroaches on the oak and the birch. Birches and the ash are extending themselves in the pine- forests of Russia, and the birch is dislodg- ing the aboriginal pines in Siberia. Mr. Frederick Ransome is making a cement from blast-furnace slag and lime, much superior to the cements previously made from this refuse matter. He uses lime from the gas-works, gets rid of the sulphur by calcination with coal or coke, and then dissipates it in the form of sul- phureted hydrogen. While Portland ce- ment breaks under a load of 818 pounds, this cement, under the same circumstances, exhibits a power of cohesion up to 1,170 pounds. The Convallaria pob/gonatum, whose name indicates its relation to the lilies- of-the-valley, may fairly be described as a traveling plant. It has a root formed of knots, by which it annually advances about an inch from the place where the plant was first rooted. Every year another knot is added, and this drags the plant farther on ; so that in twenty years' time the plant will have traveled about twenty inches from its original place. The continued publication of the " Index Medicus" has been undertaken, after ar- rangement with the editors and the rep- resentatives of the late Mr. F. Leypoldt, the former publisher, by Mr. George S. Davis, of Detroit. The first number of the journal for the current year, having been necessarily delayed, will comprise the lit- erature of January, February, and March. Further publication will be made monthly as usual. At the end of the year, in addition to the usual index of names, subscribers will be furnished with an index of subjects to the volume. i44 THE POPULAR SCIENCE MONTHLY. The Geological Society has awarded the Wollaston medal to Mr. George Busk for his researches on fossil polyzoa and pleisto- cene mammalia ; the Murchison medal to Professor Ferdinand Roemer, of Breslau ; the Lyell medal to Professor H. G. Seeley, for his long-continued work on fossil sauri- ans ; and the Bigsby medal to M. Renard, of the Brussels Museum, for his petrographical researches. The " Saturday Review " gives some more illustrations of the learning that is fostered by the English School-Board cram examinations. One is, that "the earth's axis is a pole put through the center of the sun, which turns it round." Another pupil stated that " the Nile is the only remarkable river in the world. It was discovered by Dr. Livingstone, and rises in Mungo Park." On ancient Britain the examinations brought out statements that Julius Caesar invaded the country b. c. 400 ; that the women " wore their hair down their backs, with torches in their hands " ; and that the " Druids were an ancient people, supposed to be Roman Catholics." The latest reports from Sydney with reference to the Monotrcmata state that Mr. Caldwell has exhibited specimens " show- ing the stages in the development of the monotremes from the laying of the egg to the hatching," and that Baron Miklucho- Maclay, who had found that the tempera- ture of Echidna was 82"5° Fahr., now finds that that of the Ornithorhyncus is only 76° Fahr., or more than 20° below that of man. Messrs. Schulz, Knaudt & Co., Essen, Germany, are now producing, from the ref- use of the fire-grates of the puddling and reheating furnaces, two hundred cubic me- tres of water-gas per hour, which contains forty-eight per cent of hydrogen, and forty- four per cent of carbonic oxide. The gas is used for welding and in the production of incandescent lights. The firm are about to build apparatus that will generate fourteen thousand cubic metres of the gas per day. In a recent paper by MM. Fremy and Urbain, before the French Academy of Sci- ences, attention is called to cutose, the sub- stance that covers and protects the aerial organs of plants, which is shown to ap- proach the fatty bodies in its properties and composition. It resists the action of energetic acids, is insoluble in dilute alkalies, and is not acted upon by neutral solvents, but is modified in its conditions by boiling alkaline liquids. In a recent paper before the Royal Society on " Underground Temperatures," Professor Prestwich, after considering the sources of error that affect thcrmomctric observations in collieries and mines, sug- gested, as the result of a large number of observations in mines, Artesian-well bor- ings, and Alpine-railway tunnels, that the mean thermic gradient is about forty-five feet for every degree Fahrenheit. OBITUARY NOTES. General Helmersen, a Russian officer of considerable distinction as a geologist and explorer, is dead. The death is announced of Hofrath Schmid, Professor of Mineralogy at Jena. Mr. John Francis Campbell, who re- cently died in England, was the inventor of a " sunshine recorder," a curious instrument in which the sun burned out its path for every hour of the day when visible, and in- dicated by the amount of charring the ever- varying intensity of the influence of its rays. Other instruments have been invent- ed with similar purpose, but their power is generally limited to the registration of the chemical action of the sun's rays. Mr. IIodder M. Westropp, archaeologist, author of a " Manual of Archaeology " and other works, is dead. Mr. Thomas C. Archer, Director of the Edinburgh Museum of Science and Art, died February 19th. While a customs clerk in Liverpool, he was appointed to take charge of the exhibit of that town in the Great Exhibition of 1851. lie afterward added to his usual duties the work of lecturing at local institutions and educational establish- ments, and became a professor in the Liver- pool Institution. He was appointed to the Museum in Edinburgh in 1SG0. Among his scientific publications are a text-book on " Economic Botany," and papers before the Royal Society of Edinburgh on " Graphite in Siberia," on an undescribed variety of flexible sandstone, on " Two Species of Fora- minifera," and on "some objects from the Nicobar Islands of great ethnological inter- est." Mr. Sidney Gilchrist Thomas, whose name is inseparably associated with the ba- sic or Thomas-Gilchrist process for making steel from phosphoric pig-iron, died in Paris on the 1st of February. He was educated at Dulwich College, England, and was in- tended for the medical profession, but en- tered the civil service, while he kept up all his life a strong interest in the study of chemistry. The first announcement of the discovery in iron-working which he and his relative, Mr. Gilchrist, had made, was given in a paper which he read before the Iron and Steel Institute in 1ST8, " On the Elimi- nation of Phosphorus." ALFRED E. BREHM. THE POPULAR SCIENCE MONTHLY. JUNE, 1885. AEE WE TO BECOME AFRICANIZED? Br HENEY GANNETT. DURING the past few months the presence of the negro in the United States, his future, and his possible influence upon our social and political fabric, have become a fertile subject of discussion. Thus far the argument has tended entirely in one direction, all writers seeming to be agreed that the country is rapidly getting into a bad way, by reason of its millions of black laborers. Various remedies have been prescribed, all of them more or less difficult to apply. It would appear that the wisest course to pursue would be to first study the case thoroughly, and make sure that the alleged patient is really ill, before pouring into him any nauseous draughts. It is pos- sible that he is merely a hypochondriac. In " The Popular Science Monthly " for February, 1883, there ap- peared an article by Professor E. W. Gilliam, entitled " The African in the United States," in which, by a free handling of the statistics of the last two censuses, the author attempted to prove that the colored race is increasing in this country at a much more rapid rate than the whites, and that consequently, unless some effectual preventive meas- ure against this increase be taken at once, we are in imminent danger of becoming Africanized. He proposed, as the cure for the impending evils, a wholesale, forced migration of the colored people. This article is re-enforced by another from the same author, in the November number of the " North American," in which the same views are reiterated. As these articles have attracted much attention, it is desirable to notice them in some detail. The argument upon which Professor Gil- liam bases his conclusion that the negroes are increasing faster than VOL. XXVII. — 10 146 THE POPULAR SCIENCE MONTHLY. the whites runs as follows : During the decade 1870-'80 the whites increased, upon the face of the returns, 29 per cent, and the blacks 34 per cent. From the former rate of increase he subtracts 9 per cent, to account, as he says, for foreign immigration, leaving 20 per cent to represent what he calls the native increase. From the per cent of in- crease of the blacks, he deducts 5 per cent to allow for his surmise as to the extent of omissions in the ninth census, "leaving 30 per cent " (sic). Then he restores the 5 per cent, making a normal rate of in- crease of 35 per cent for the blacks, on the ground that in the future they will increase more rapidly than in the past. It can not be denied that, with these rates of increase for the two races, Professor Gilliam is well equipped for the task of Africanizing the country, and, if these figures, or any approach to them, are correct, we may well feel anxious for the fate of the " white man's government." With these figures as a basis, Professor Gilliam goes on to predict the population a century hence, with results as follows : Northern whites, 240,000,000 ; Southern whites, 96,000,000 ; Southern blacks, 192,000,000. An analysis of the author's curious method of deducing these re- sults will, however, aid to dispel this frightful vision of the future. The increase of white population between 1870 and 1880 was slightly less than ten millions. The number of immigrants during this period was a little in excess of two million eight hundred thousand. Sub- tracting the latter from the former, there is left a number which is 23 per cent of the population in 1870, not 20 per cent, as Professor Gil- liam has it. But what does this 20 or 23 per cent (it matters not which) represent ? Certainly not the increase of native whites, as he interprets it. The census gives directly the numbers of native whites in 1870 and in 1880, and the proportional gain of this class during the decade was not less than 31 per cent. These are the figures which he should have used in making his comparisons. Now as to the increase of the colored element. Professor Gilliam, at the outset, deducts from its rate of increase 5 per cent, representing about a quarter of a million persons, on account of the imperfections of the census of 1870. Concerning the omissions of this census little is known, except that they were generally distributed through the cotton States, were largely, if not mainly, of the colored element, and, of that element, approximated nearer three fourths of a million than one fourth, and certainly exceeded half a million. Professor Gilliam's subsequent addition of 5 per cent, " as an obvious consideration points to the conclusion that the blacks will for the future develop in the South under conditions more and more favorable," certainly is not warranted by the facts or the probabilities, and, as we are reasoning from what has been and is, and not from what may be, it looks very much like begging the whole question. Correcting Professor Gilliam's statements, it appears that the ratios ABE WE TO BECOME AFBICANIZED? H7 of gain during the past decade were, as nearly as can be known, as follows : For native whites, 31 per cent ; for blacks, not above 25 per cent. But all such comparisons, based upon the results of the ninth cen- sus, are utterly worthless. No reliable conclusions regarding the in- crease of negroes can be drawn from a comparison in which these sta- tistics enter. The extent of the omissions can be a matter, within cer- tain wide limits, of conjecture only. The only comparisons which yield results of any value are those made between the statistics of the eighth and tenth censuses. That the former was, to a certain slight extent, incomplete, is doubtless true, especially in regard to the col- ored element, but the omissions were trifling as compared with those of the ninth census. A comparison between the results of the eighth and tenth censuses shows the advantage to be clearly in favor of the native whites, who increased 61 per cent in the twenty years, while the colored element increased but 48 per cent. This great increase of the native whites was effected in spite of the fact that the ranks of the adult males were depleted to the extent of over a million by the casualties of war, which the negroes scarcely felt. This relatively greater increase of the whites is sustained by the record during the days of slavery. In but one decennial period since 1790 did the negroes increase as rapidly as the whites, and in most cases their increase was far less, as appears in the following table, ex- tracted from Scribner's " Statistical Atlas " : DECADE. PERCENTAGE OP INCREASE. White. Colored. 1790 to 1S00 35-76 36-13 34-12 34-03 34-72 37-74 37-69 24-76 29-21 32-38 1800 to 1810 , 37*46 1810 to 1820 28-57 1820 to 1830 31-41 1830 to 1840 23-28 1840 to 1850 26-61 1850 to 1860 22-06 1860 to 1870 9-86 1870 to 18S0 3485 It will be noticed that the only period during which the colored element increased faster than the white element was between 1800 and 1810, during the continuance of the African slave-trade, which ceased in 1807. It will also be seen that the rate of increase of the negroes, while irregular, shows a marked and rapid decrease — a much greater decrease than that of the whites — even up to 1850, when immigration from Europe began to make itself felt. This decrease of the colored race in proportion to the whites is set forth still more strongly in the following table, quoted from the same work : 14.8 THE POPULAR SCIENCE MONTHLY. CENSUS. PBOPOKTION OF— Whites. Colored. 1790 80-73 81-13 80-97 81-61 81-90 83-17 84-31 85-62 87-11 86-54 19-27 1800 . 18-87 1810 19-03 1820 18-39 1830 18-10 1840 16-83 1850 15-69 1860 14-13 1870 12-65 1880 13-12 Between 1790 and 1860 the proportion of colored to total popula- tion is seen to fall from over 19 per cent to but little in excess of 14 per cent — a decrease of fully one fourth. In the half-century which elapsed between the date of the first census and 1840, during which time immigration was very slight, it decreased not less than 2T\4o per cent, although for one third of this period the slave-trade was being carried on. Such being the history of the negroes in ante-helium days, when they were property, and when every consideration of self-interest prompted their owners to watch over their health, to encourage child- bearing, and to protect and preserve the children, is it to be supposed for a moment that this careless, improvident, ignorant race, thrown suddenly upon its own resources, should at once, or within a genera- tion, take on a rate of increase more rapid than before emancipation ? The wonder is, that in the past twenty years they have not fallen fur- ther behind. Considering the colored race in this country as a whole, it is seen that it has not held its own, either in a state of slavery or thus far in freedom. It is but another illustration of the fact, that an inferior race can not thrive side by side with a superior one. It would seem, therefore, under the circumstances, more profitable to study ways and means for preserving and strengthening the manual labor element of the South, rather than to debate the methods of getting rid of it. In " An Appeal to Caesar," by Judge Tourgee, the question of the future of the colored element is discussed from a somewhat different point of view. Without committing himself as to the increase or de- crease of the colored element in the country at large, in proportion to the whites, the author finds, upon a somewhat superficial study of the statistics bearing upon the question, that in the South Atlantic and Gulf States the negroes have increased decidedly in proportion to the whites, while in those States which he classes as border States they have relatively decreased. This massing of the negroes in what may, for convenience, be denominated the cotton States, coupled with the steady sharpening of the line of separation between the two races — a line which, as the author claims, becomes more and more accentuated ARE WE TO BECOME AFRICANIZED? 149 as the inferior race increases in numbers and advances in education — will lead to inevitable conflict between the two races. As the negro becomes numerically the stronger, and, through education, appreciates more fully his present position, he will commence a struggle for the mastery, and then the days of the Ku-klux will be eclipsed in blood and slaughter. Such is the condition to which these ill-fated States are hurrying. To ward off this impending evil, Judge Tourgee urges upon the General Government the work of educating the blacks. Such, in brief, is the " Appeal to Caesar." Education seems to be regarded as a universal panacea for all the ills of the people, but in this case, according to the author's own state- ment of the situation, the education of the negroes would but pre- cipitate the impending conflict. Our only safety would seem to be in leaving them in ignorance. The whole " Appeal " is based upon the theory that the negroes are migrating southward from the border States into those of the South Atlantic and the Gulf in great numbers. This theory the author attempts to establish by deductions from census statistics. It may, in passing, be suggested that a careful revision of his figures will show many important arithmetical errors, which may modify very sensibly some of his conclusions. It is unnecessary to follow his methods of reasoning, as the truth regarding the questions at issue can be arrived at much more directly. The fact is, that the negro is not migrating southward. There is no massing of the col- ored people in the cotton States. In 1860 the colored element of these States formed 66 per cent of the colored element of the country. In 1880 it formed precisely the same proportion. Between 1860 and 1880 the colored element of the country increased 48 per cent. The same element of the cotton States increased, in this interval, in pre- cisely the same proportion, neither more nor less. These figures are conclusive upon this point, and from them there is no appeal. But the fact remains that, in these cotton States, the colored ele- ment was in 1880, in comparison with the white element, slightly stronger than it was twenty years before. This, however, is due not to a southward movement of the colored people, but to a decrease in the rate of increase of the whites of those States. While the increase of the native white population in the country at large between 1860 and 1880 was sixty-one per cent, that part of the same element resi- dent in the cotton States increased but thirty-nine per cent. This low rate of increase among the whites might seem to establish Judge Tourgee's position, though not in the way he states it, were it not for the fact that three fourths of this increase took place during the dec- ade between 1870 and 1880. The increase of whites in the South received a most effectual check during the four years of war, in which every male capable of bearing arms was in the field, and in which fully half a million laid down their lives. Since the war the white ISO THE POPULAR SCIENCE MONTHLY. race has taken up a rate of increase equal to, if not greater than, that of the country at large, a greater rate than that of the colored people within its borders, and there is no apparent reason why they should not maintain it. It is not, then, a migration of the negroes southward which has caused their relative gain in these States, but it is the losses of the white race — losses which, however, are rapidly being repaired. As the negroes are not increasing as rapidly as the whites, either in the country at large or in the cotton States, and therefore are des- tined to become constantly of less numerical importance, the pressing necessity for doing something to ward off the evils predicted by the authors above quoted does not appear to exist. -♦*♦- THE NEKVOUS SYSTEM AND CONSCIOUSNESS. Br W. K. BENEDICT, PEOFESSOB OF PSYCHOLOGY AND LOGIC IN THE UNIVERSITY OF CINCINNATI. in. WE are beginning to hear lamentations over the realism of our time. Not only are the gods dead, God is dead. Art finds no place for Imagination, save in setting her to devise ways and means for a more complete photographic process. Among the crimes laid to the account of Science, this is not the least ; indeed, perhaps this may sum them all, that she has taken away our Lord and will show us nothing in return but the geologic formation of a sepulchre. While this charge is unjust, radically unjust, it must be allowed that the manner of commendation employed by many advocates of science is responsible, in large measure, for our bread-and-butter attitude. The fault lies in the original constitution of certain men — not that they are scientists, but that they are small scientists ; men for whom a formula, or a compound, or a root, or a fact whatsoever, is the end. To know the most names of the most classifications is to be saved, to apply chemistry in the manufacture of salable beer is to make " calling and election " sure. The devotion of these little men to science is not only at the expense of all that is highest, but is, as was intimated, largely responsible for the realism over which so many weep. Men of sci- ence, that is to say men of science, are not accountable for deadness of soul. The wonder with which those early Greeks looked out upon the face of all things may not for one instant be compared with the wonder that fills the soul to-day before this stupendous universe : " Die Geisterwelt ist nicht verschlossen : Dein Sinn ist zu, dein Herz ist todt." Because we have learned that color is not in sunset or rose, is there therefore no color ? Is the marvel anywise diminished by knowing THE NERVOUS SYSTEM AND CONSCIOUSNESS. 151 that, upon matter so adjusted and so acting as the brain is adjusted and acts, all color depends ? Because there is no sound in bell, or breeze, or ocean, is there therefore no sound ? And wherein is the wonder of it diminished when we have learned the construction of the ear, its possible relation to a particular fold in the brain, and the neces- sity of this for all the harmonies that fill the soul with glory ? Are we, the thinking, sorrowing, hoping selves, any the less real because all this thinking, all this sorrowing, and all this hoping depend in strictest sense upon that most highly organized form of matter the human brain ? George Eliot spoke truly when she said, " To advance in knowledge is to outline, more perfectly, our ignorance " ; and who does not won- der before the unknown ? When man is brought, as, if he is capable of it, science will bring him, face to face with the darkness of mystery, does he boast himself of all that he has learned? "We may rest assured that the glory of mystery has not departed from off the face of the heavens or of the deep. I know not where this mystery is greater, or the wonder of it more manifest, than in the relation which obtains between the brain and consciousness, between the brain and the per- sonality that thinks and feels and wills. This relation is a fact. All that we call our soul-life, from the sensations, the " building-stones " of this life, to the most abstract thought and holiest desire, stands de- pendent upon the activities of nerve-matter. Surely no one will be led to say, so are these things dependent on stomach, lungs, and heart. Such dependence is indirect, mediate, the other direct and immediate. Between consciousness and the brain, between nerve-matter and our- selves, there is a relation close, constant, immediate ; we may well strive to reason upon the character of this relation. Here at the out- set, this term reason must have clear meaning. I intend to use the word as expressive of the process of inferring, of drawing a conclu- sion from premises. I have now no concern with those who intui- tively perceive truths beyond the territories of sense and inference. Those for whom the immateriality of the soul is a direct deliverance of consciousness may smile at the crawling pace of my induction ; still, it is an honest and a needful endeavor to search after those con- clusions respecting brain and consciousness which the inductive, infer- ential process shall necessitate. In such search, nothing, as I think, is more important than to be assured that, in reasoning from the knowledge given by our senses to conclusions which transcend such knowledge, we must proceed accord- ing to discerned resemblance. Two things agreeing with, which means, for us, resembling, one and the same third thing, agree with, that is resemble, each other ; and two things, of which one agrees with, that is, for us, resembles, and the other does not agree with, that is, for us, does not resemble, a third thing, do not resemble each other. If the manifestations of Is2 THE POPULAR SCIENCE MONTHLY, nerve-matter and the manifestations of consciousness disagree, seem unlike after our best examinations, it is unreasonable to give them a common cause*, they can not, by us as rational beings, be brought into such close relation. Permit me to ask attention to a further consideration. Neither the direct knowledge given b\ our senses, nor this inferred knowledge, furnishes a solution of the mystery which belongs to the subjects we investigate. It is often said and as often forgotten that all explana- tion of natural processes consists solely in the resolution of involved combinations of activities into their elements. We make a false de- mand of the evolutionist when we insist that he shall tell us how the biological is evolved from the a-biological, and he makes a false de- mand of the spiritualist when he requires to be told how mind acts on brain or brain on mind. There is no such thing as being told the how of what takes place. The starting-points are unknowable in their nature and in the reasons of their operations. If I have not completely misunderstood that vigorous book, " Modern Physical Con- cepts," the purpose of its writer was to show that the so-called bases of physical science do not represent entities any more than the terms vitality, justice, humanity, law, represent entities, but that the bases of physical science stand for the present highest generalizations of the mind working inductively, that these bases do not exist out yonder among the spaces, but here within the thinker, and that when we affirm matter to be, outside of us, exactly thus and so, force exactly thus and so, we are but repeating the mediaeval procedure of declaring that beneath the oak-tree there is an oak nature, beneath human beings a human nature. Judge Stallo, as I think, found the mind at its old trick in modern physical science, the trick of actualizing, and thrusting out yonder into space, its thoughts, its concepts, and of worshiping them as lords of all, explainers forever. Service is ren- dered here, not for orthodoxy as against heterodoxy, not for spiritual- ism as against materialism, but for all truth as against all error. We need to keep in mind that the only thing which can be accomplished by science, or by philosophy, as the unification of the sciences, is a detection and expression of resemblance between phenomena and between the modes of their activity. This may give us a law of evo- lution extending over all manifestations, a law not perched up on matter compelling it to evolve, but a law expressive of our feeling of similarity where we had previously felt diversity. This resemblance is detected by observation. Now, observation is a process, not a thing. Its character is never determined by the ob- ject observed. Observation is not an instrument possessed by the physicist alone. Observation is an intellectual operation, and may be as genuine, as honest, when directed to thoughts, emotions, volitions, as when brought to bear on stars, rocks, or brains. The time has come when the truth shall assert itself that philosophy is an attempt THE NERVOUS SYSTEM AND CONSCIOUSNESS. 153 to unify all our experiences, an attempt to be able to say that whereas here and here and here my experiences seemed unlike, separate, they now seem alike and conjoined. The application of all this to man is plain ; indeed, has been for these past years most impressively operative. Formerly, man was supposed to possess an intellectual and moral nature distinct in kind ; in him was thought to reside a force peculiar, above and beyond all other forces. Observation has had much to say, as many believe, in contravention of these conclusions ; and it is now well known that the doctrine of evolution is brought to bear on all sides of human psychology in a way special and searching. I have not here in mind the work of Spencer or Bain, or their immediate disciples. Within very recent days books have been published which show painstaking research in distinct psy- chological departments. Ribot has discussed the physiology and pa- thology of memory ; Grant Allen has offered help in the " tangled territory " of aesthetics ; Leslie Stephen has written a science of ethics, stating as his purpose, " to lay down an ethical doctrine in harmony with the doctrine of evolution " ; G. H. Schneider, author of a work on the animal will, has just published a careful treatise on the human will from the stand-point of the modern development theory ; Professor Preyer, at Jena, has set out the results of his observations on the soul of the child — observations made with greatest care three times each day during the first three years of child-life. I might extend my list at length ; for this there is no need. We are face to face with the question of the relation between brain and consciousness. I have said that this relation is positive and constant, though few, except physi- cians, realize the meaning of such a fact. It means, in the first place, that changes of consciousness coincide with molecular changes in the brain. For every alteration in consciousness, however slight and tran- sient, there has been a molecular change in the brain. This relation means, in the second place, that there is a physical basis for memory. Whether we accept or reject localization of functions in the cerebral hemispheres, we must believe that the cell-modifications which coin- cide with specific sensations remain permanently, thus furnishing a physical, organic requisite for memory. In the third place, this rela- tion means that, in a recollection of any of our experiences, there is presupposed a renewed activity of those very portions of the brain which assisted in the experience. There are no transcendentalists so transcendental that they may transcend this direct relationship between what they are pleased to call gross matter and their sublimest ecstasy. What opinion must we form as to the nature of this relation ? We have choice of two conclusions which are alternatives. We may say the relation of brain-matter and consciousness is one of corre- lation, conversion — or we may say it is one of instrument to person- ality. Personality is here, as everywhere, a term chosen to represent a series of manifestations so alike among themselves and so unlike all i54 THE POPULAR SCIENCE MONTHLY. other manifestations as to necessitate a specific designation. By adopt- ing the term personality, we should affirm our belief in the existence of some form of being, which, for us, is persistently unlike every other form of being with which we come into relation. Here the element of speculation, which is a necessary part of all reasoning, appears. Whether we accept correlation or personality, we accept what can no more be directly Tcnown than the mortality of men now living, or the return of the seasons. All reasoning is beyond the facts, and is in this a speculation ; but reasoning need be no more an unsafe guide on such subjects as the one before us than on any of the complex affairs where we gladly trust its teachings. Our demand of Reason must be that, though she lead us beyond the facts, she shall never lead us contrary to the facts. Again, I would say, it should be recognized that neither of the conclusions above indicated is a solution of the mystery attend- ant upon consciousness. The pride of the little scientists induces them all too often to declare that, by the first of these alternatives, they have cleared away the obscurity which they love to call metaphysical and let in the white light of comprehension. So, in turn, the other party, seizing hold of the fact of personality, forthwith affirm that, by it, man's immateriality, immortality, and di- vinity, are forever made visible in the light of consciousness. All this is quite aside from that inferential process which, as reasoning beings, we should prescribe for ourselves. Is the relation between brain and consciousness one of correlation ; may we, according to the evidence, believe it to be one of correlation ? Physiological materialism is an extension of the doctrine of correlation to consciousness. It is needful to know what is meant by correlation. Correlation is a necessary, reciprocal production. " Any force capable of producing another may be produced by it. Each mode of force is capable of producing the others, and none of them can be produced but by some other as an anterior force. The various affections of matter, heat, light, electricity, have a reciprocal dependence ; either may produce or be convertible into any of the others." The materialism of physiology extends this doctrine of correlation to consciousness. The well-worn language of Professor Huxley (" Darwin and his Critics ") is again in point. " As the electric force, the light-waves and the nerve-vibra- tions caused by the impact of the light-waves on the retina are all ex- pressions of the molecular changes which are taking place in the elements of the battery, so consciousness is, in the same sense, an expression of the molecular changes which take place in that nervous matter which is the organ of consciousness." A short sentence from Dr. Carpenter to the same effect : " There is just the same evidence of what has been termed correlation between nerve-force and that pri- mary state of mental activity which we call sensation that there is between light and nerve-force." Now, the proposition, fundamental to my paper, is that such a conclusion can not rationally be drawn, un- THE NERVOUS SYSTEM AND CONSCIOUSNESS. 155 less the characteristics of consciousness, as we know them and are obliged to know them, resemble the characteristics of brain-activity as we know them and are obliged to know them. It will not avail to say there are striking differences between heat, electricity, and light ; there are striking resemblances — one positive, constant resemblance — they are all modes of motion. Between the characteristics of con- sciousness and the characteristics of nerve-matter, as we know them, there are no resemblances whatsoever. If the smaller physiological materialists (for the larger do it fully) would but think it worth their while, and a truly scientific procedure, to fasten their attention upon consciousness, they might be struck by its peculiarities. The distinct- ive features of consciousness in general have often been indicated. I shall restate them here as they have been compared with nerve-activi- ties, arranging them in pairs for the sake of clearness : 1. Nerve-activities : All are modes of extension and motion. Consciousness-activities : None can be conceived as extended or moving. 2. Nerve-activities : They may be observed through the senses. Consciousness-activities : They are never known through the senses. 8. Nerve-activities : They are external to the observer. Consciousness-activ ities : They are internal to the observer. 4. Nerve-activ ities : Each may be directly seen at the same time by many observers. Conscio usness-activ ities : They can be directly known by one person only, viz., he who experiences them. 5. Nerve-activities : They consist of parts external to each other and are divisible. Consciousness-activities : They have no distinction of parts and are indivisible. It may surprise some readers to be told that this contrast is fully recognized by many leading upholders of evolution. Mr. Spencer says, " There lies before us, in the study of consciousness, a class of facts absolutely without any perceptible or conceivable community of nature with the facts that have occupied us in the study of the nerv- ous system." Dr. Tyndall (" Address on Scientific Materialism," Norwich) says : " The passage from the physics of the brain to the corresponding facts of consciousness is unthinkable. The chasm between the two classes of phenomena is intellectually impassable." Professor Huxley says : "I know nothing whatever, and never expect to know anything, of the 156 THE POPULAR SCIENCE MONTHLY. steps by which the passage from molecular movement to states of con- sciousness is effected. I entirely agree with the sense of the passage from Dr. Tyndall." In view of the dissimilarity, the thorough dissimilarity, between nerve-activities and consciousness-activities, we are not justified in regarding the former as the sole cause of the latter. Chemists, after a somewhat protracted examination of the substances found in nature, announce the discovery of sixty-four different bodies, from which they can not, by any means now at hand, separate simpler substances. This does not intend to say that these sixty-four elements are absolutely simple, but that " they are so as far as our knowledge extends." Now, why are these sixty-four elements maintained to have a real existence ? Why is aluminium believed in as a fact distinct from antimony, or arsenic as a fact distinct from bromine, and so on throughout the list ? Because, and simply because, the states of consciousness are persist- ently distinct when dealing with these so-called elements. The chem- ist is unable to experience resemblance between the actions — i. e., the manifestations — of aluminium and antimony. Therefore, and there- fore alone, he says, there are here different substances. This is the kind of reasoning, and no other, that we wish applied to the subject of our examination. If the passage between brain- activity and consciousness-activity be unthinkable, intellectually im- passable, why is it so ? Not from any a priori or "high-priori " incon- ceivability, but because these activities persistently fail to resemble one another, i. e., to produce in us similar states of consciousness. They can not be rationally called " diverse operations of energy mutually con- vertible like light, heat, and the other physical forces." Such corre- lation is opposed through and through to experience. Here is the irrationality of physiological materialism. This materialism makes a break in the physical continuity of Nature's workings; a break found nowhere else ; a break, moreover, which is not found here by any exam- ination of which we are capable. Correlation requires that motion should be transformed into some- thing not motion, and then resume its course as motion. Motion set up at the periphery of the body produces a definite and measurable quantity of motion in the brain ; this is well called a mechanical prob- lem out and out. We find no measurable consciousness, yet conscious- ness is a reality ; we find no break in physical processes elsewhere, yet, if correlation be true here, such a break there is. It will, I hope, be clearly seen that this difficulty is nowise related to the old and worth- less difficulty thought to be suggested by those who ask the material- ist how motion is transformed into consciousness. As to the how of things they have learned most who have learned that they know noth- ing. The question is not how are brain-motions transformed into con- sciousness, but the question is exactly this, What ground have we to believe that such transformation exists ? THE NERVOUS SYSTEM AND CONSCIOUSNESS. 157 Permit me to repeat the statement that there is no reasoning here along the " high-priori " road of inconceivability. I see no more incon- ceivability in supposing that a brain-change should be followed by a thought than that it should be followed by an increased secretion. The thing needed is, to know the fact in the case. Are brain-changes transformed into consciousness, or does the soul, on occasion of these changes, respond in its peculiar language ? The brain-changes, as we know them and must know them, consist of attractions, repulsions, motions, and co-ordinations of the brain-particles. These, according to the physiological materialist and the young physi- cian, are transformed into states of consciousness, which states are not material changes, but separated from them by a chasm " intellectually impassable." It has been wisely said that the position which a thor- ough-going scientific evolution ought to defend is this : thoughts, feel- ings, volitions, any and all states of consciousness, have no existence for physical science. Indeed, the annoyance caused by consciousness as a useless "surplusage" is nowhere more strikingly illustrated than in the following passage from Professor Huxley's paper " On the Hypothe- sis that Animals are Automata." The author writes : " Though we may see reason to disagree with Descartes's hypothesis that brutes are unconscious machines, it does not follow that he was wrong in regard- ing them as automata. We believe, in short, that they are machines, one part of which (the nervous system) not only sets the rest in motion and co-ordinates its movements in relation with changes in surround- ing bodies, but is provided with special apparatus, the function of which is the calling into existence of those states of consciousness which are termed sensations, emotions, ideas. It may be assumed, then, that molecular changes in the brain are the causes of all the states of consciousness in brutes. Is there any evidence that these states of consciousness may, conversely, cause those molecular changes which give rise to muscular motion ? I see no such evidence. The frog walks, hops, swims, quite as well without consciousness as with it, and if a frog, in his natural state, possesses anything corresponding with what we call volition, there is no reason to think that it is anything but a concomitant of molecular changes in the brain which form part of the series involved in the production of motion. The consciousness of brutes would appear to be related to the mechanism of their body as a collateral product of its working, and to be as completely without any power of modifying that working as the steam - whistle which accompanies the work of a locomotive-engine is without influence upon its machinery. Their volition, if they have any, is an emotion (?) indicative of physical changes, not a cause of such changes. It is quite true that this reasoning holds equally good of men, and therefore that all states of consciousness in us, as in them, are immediately caused by molecular changes of the brain-substance. It seems to me that, in men as in brutes, there is no proof that any state of consciousness is the 158 THE POPULAR SCIENCE MONTHLY. cause of change in the motion of the matter of the organism. If these positions are well based, it follows that our mental conditions are sim- ply the symbols in consciousness of the changes which take place auto- matically in the organism, and that, to take an extreme illustration the feeling (?) we call volition is not the cause of a voluntary act, but a symbol of that state of the brain which is the immediate cause of the act. We are conscious automata." (The italics in the above quo- tation are the present writer's.) This passage, published in 1874, will remain unique as an attempt to " get on " in our examination of man without consciousness. Consciousness is a collateral product of brain- change. Whatever may be meant by " collateral," it can not be so one-sided an affair as to save the break in physical continuity pre- viously described. If consciousness be at all the product of brain- changes, it appears, and must appear, as a stranger to these changes, destitute of a single one of their features. Further, and with sincere deference, I would say that the reasoning in the passage before us seems to me peculiar. Consciousness is produced by brain-changes ; nay more, these are the sole cause of consciousness, and yet there is no ground to believe that consciousness in its turn ever occasions brain- changes or muscular movements. Volition is not the cause of a volun- tary act, but a token that such an act is taking place. This would be termed in logic a contradiction, both in form and matter. When we are told that consciousness is completely without the power of modifying the working of our body, we do, indeed, feel that consciousness might as well give up and cease to be ; at the same time we know that consciousness, in the shape of volition, is adjusting, direct- ing, and in manifold other ways modifying our organism from day to day. My reason for bringing up this disposition of consciousness was not so much to show its deficiency (which has been well done by Dr. Carpenter and others), as to insist upon the fact that consciousness is not susceptible of scientific treatment by any physical or physiologi- cal method. I wished also to show that no half-way recognition of consciousness would meet the demands of investigation. Perhaps the chiefest benefit to come from the physiological psychology of our day will be in this, that it will make unmistakably clear its own inadequacy for a treatment of consciousness as such. I trust I may not be misun- derstood in this remark. I yield to no one in the belief that an ines- timable advantage has been conferred on psychology by physiology. It is now possible to study the sensations, both general and special, with a thoroughness unknown a few years since. The intimacy of connec- tion between brain-changes and what we term soul-states has been once and for all established and proclaimed. Much may be accom- plished toward a localization of functions in the hemispheres ; the time may even come when people at large shall know that most of their stupidity, peevishness, and sin, results from unhealthful brain-activity. The relation between digestion, ventilation, sleep, and morals, may THE NERVOUS SYSTEM AND CONSCIOUSNESS. 159 attain general acceptance, to the destruction of a huge load of the world's misery. All this and more may come, but physiology will never remove or investigate a state of consciousness ; it will never front the inner side of a single sensation. This, if I mistake not, is the annoying thing to many specialists. The resort has, for a long time, been a vigorous pooh-poohing of consciousness, or a ridicule of it as somehow synonymous with metaphysics and nonsense. It is a singular and natural thing — singular in its intensity and narrowness, natural in its origin — this conviction among many of the younger spe- cialists that logical and psychological investigations are but rattle- boxes for babes and fools. The natural origin of this, I say, is plain. The chairs in many of our colleges and universities are occupied by men nobly endowed by nature for their special studies, and culti- vated through years of investigation abroad. They have not, however, escaped the working of the association of ideas. All they have ever known about psychology, logic, or ethics, dates back to a few hours' perfunctory stumbling over the pages of Haven's " Mental Philosophy," Day's " Logic," Wkately's " Logic," Thompson's " Outlines of the Laws of Thought," Butler's " Analogy," Haven's " Moral Philosophy," or, if specially fortunate, Hamilton's " Metaphysics." These exercises in torture were held during those groping years of college-boy experi- ence. Here were given all the facts ever furnished for coming to an understanding of the processes of thought or the principles of morals. Interest in these matters, an interest natural to all who share human nature, was blasted at the outset of its development. Other pursuits that could and did take on the semblance of reality fastened attention, and led to the years of toil that fitted for life-work. What more nat- ural than that henceforth (must it be said forever ?) each approach to the subject of consciousness is, for these minds, an approach to confu- sion worse confounded ? The fact that I occupy a chair in Philosophy will very much weaken the force of what I am about to say ; still, the conviction will get itself expressed with whatsoever power it may have. The work of the workers would rise faster, stand firmer, come to more universal recognition, if guided by some living logic, and some appreciation of the processes of thought, emotion, and will. The fact is, that in consciousness and in consciousness alone all things are known. No physicist ever fronted or ever will front a pure fact, a thing as it is, apart from consciousness. What the physicist knows are not sub- stances in themselves, out of consciousness. Force and matter are, in the way in which he uses them and must use them, products of his consciousness. He, the conscious person, is affected so and so, that is, is made to have such and such states of consciousness ; to the common or resembling elements in these states, he gives a common name, be- lieving, beyond a doubt, in the existence of a cause for these states, but often failing to realize that such cause is unknown and unknow- able, not at all revealed, in its essence and apart from consciousness, 160 THE POPULAR SCIENCE MONTHLY. by the abstract terms which he has formed to express it. The physio- logical materialist can never meet the demand which a proof of his belief requires, viz., that he should be able to consider the nervous system apai't from consciousness before declaring it the sole cause of consciousness. All that is known of the nervous system is known through consciousness ; is there, then, no importance, no necessity, for some examination of consciousness for those who would give an account of their knowledge, be its content what it may ? This position, rightly understood, will vindicate my assertion that, for all forms of investiga- tion, the need at present is a critique of knowing, a critique which shall be not simply a "Zuriickgehen auf Kant" (profitable as this might prove for an understanding of his relation to materialism), but a critique which shall embody the contributions of recent years from investigators in the territories of the senses, the understanding, and the emotions. It may be asked, Why should this appeal for consciousness come so late in the present discussion ? Ought it not rather to have preceded the statement of the characteristics of consciousness, and so prevented a break in the course of thought ? Such a break is, of course, unde- sirable ; still, it is one not to be avoided, as I think, under the circum- stances. There remain for consideration certain special features of con- sciousness, for whose examination and estimation special entreaty was needed. This solicitation will have more force when placed in direct connection with the features themselves. The writer ventured to hope that those broader, more noticeable characteristics of conscious- ness which lie, as it were, upon the surface, might be left to awaken attention by their size. Not so with matters now to be brought for- ward. While there is no purpose to leave, even for an instant, the territory of experience, we enter a j)ortion of that territory which, to many, will be new, and therefore, without effort against prejudice, un- true. There are certain special facts in consciousness, i. e., ceilain dis- tinctive features in each person's experience, which prevent, out and out, the acceptance of correlation as a proper account of the relations between brain and consciousness. Few would refuse to admit that sensation is a fact, yet there is danger of studying sensation with the sensation omitted. Every sensation has four physical antecedents which, though dis- tinct, are not different in kind from one another. This is such a pre- ponderance of the physical that the other element is likely to go un- noticed. The physical requisites for every sensation are : 1. Some outward, exciting cause or excitation — this is physical movement, nothing else ; it may be of ponderable matter or of an imponderable instrument, as light. 2. The contact of this physical condition of movement with a sensitive portion of the body. 3. The excitation- THE NERVOUS SYSTEM AND CONSCIOUSNESS. 161 condition of the sensitive nerve-fibers. This is produced by the out- ward irritation, but is a purely physical and inward nervous process, having no other resemblance to its cause than that it is motion, and having no resemblance to the sensation which is conditioned upon it. 4. The transfer of this condition of the nerve-fiber to the central parts of the nervous system, especially to the brain. These are the mechani- cal antecedents for sensation. They are susceptible of physical treat- ment. They may, and often do, operate without any sensation arising ; more than this, they may operate so as to produce a reflex activity, causing violent motions, still without the faintest appearance of sensa- tion. It is plain, then, that to know anything about sensation we must pass from physiology to personal experience. It seems a just charge against the materialism of physiology, both general and medical, that it takes no account of the element in a sensation-process. How shall we escape saying that the last step in this process is the sensation itself, which the soul calls forth from itself in consequence of the antecedents described ? The sensation is no picture of the outer thing, the retinal image works, in all probability, chemically upon the retina, but that image does not and can not get itself transferred to the cerebral hemispheres. The sensation is an answer to the excitation in the brain-mass, arising from that image, an answer in such peculiar language that it must be called language of the soul — not as thereby explaining it in the sense of resolving its mystery, yet as thereby ex- plaining it in the only way in which explanation is anywhere possible, viz., by resolving the combined activities into their elements. It is a necessary part of this discussion to note that one of these elements is personality, i. e., a consciousness of the sensation as mine. It seems unfortunate that, in dealing with this experience of personal- ity, the strength and weakness of the development theory are not rightly estimated. The strength of the theory lies in those rudiment- ary sensations connected with infant life, and with the organic pro- cesses where it seems but just to say that only feeling is present, i. e., no true consciousness, no knowledge of the sensation as mine. The weakness of the theory, and it is a fatal one, lies in the failure to recognize the distinction between a matured idea of self which comes only with years, and a consciousness that the sensation is mine, how- ever rudimentary this sensation may be. The most primitive distinc- tions in consciousness, those of pleasure and pain, can not be expe- rienced without being known. When this is realized, the inadequacy of the attempt to dispense with personality, or to derive it from any- thing more elementary than itself, must appear ; the two factors in every phenomenon, viz., that which manifests itself, and that to which it manifests itself, are at once disclosed. Memory, which, though lying in the so-called fog-land of conscious- ness, is yet a reality, has been brought forward as decisive against the application of evolution to the origin of knowledge. Memory is a pre- VOL. XXVII. — 11 162 THE POPULAR SCIENCE MONTHLY. requisite for all psychical development. Unless we can compare the experience of yesterday with the experience of to-day, any advance of ourselves from the brute condition is impossible. Now, such compari- son demands that the first experience should have been known as mine. From this demand there is no escape. Complying with it, something, some form of being called personality, must lie at the bottom of the inner side of our nature. Lotze has pertinently said : " We have this unity of consciousness not because we appear to ourselves to have it ; we have it because we appear to ourselves to have it." In each sensation there is consciousness of self in a particular state. Our sensations are varied and successive. We hear the sound of a bell, then of a railway-train, then of the wind ; we see cloud, moon, and mountain-top. Here we have the sensation, the succession of sen- sations, the discrimination of sensations, and discrimination of things by the sensations. Devolve this whole business upon nerve-matter in the cei'ebral hemispheres. Is such ascription of functions rational ? Is it in keeping with our knowledge of brain-structure ? If we sur- mount the difficulty of transformation of motions into non-motions (that is, consciousness), what provision do we anywhere find in the hemispheres for the unification of such sensations as above described, their unification in self ? A further question at once arises. Physiology has arranged for diversity of result. What has it done toward comparing these differ- ences ? By comparison, and by that alone, each sensation is known as distinct from every other. All that physiology offers or can offer is the integrity of each nerve-fiber. As has been justly said, this fiber is like every other in construction and action. What provision have we, apart from personality, for detecting difference in sensations? Personality is the place at which both parties should expend their strength. Mr. Mill and Mr. Bain, understanding this, have sought to obliterate the distinction between feeling and self-consciousness. They have maintained the priority of an impersonal feeling. Here is the starting-point, not in personality, but in feeling. Personality is a de- velopment from impersonality by what Mr. Mill calls a " process of reference." This is one of those magical terms, like the newer word "functionate," which serve to obscure the failure of an undertak- ing. Mr. Bain also starts with a nervous system and feeling, and gives what may be taken as the latest expression of the movement to- ward unification of soul and body. He says : " The arguments for the two substances — mind and matter — have, we believe, entirely lost their validity ; they are no longer compatible with ascertained science and clear thinking. One substance with two sets of attributes, two sides (a physical and a mental), a double-faced unity, would appear to comply with all the exigencies of the case." This assertion of a double-faced unity not only fails to bridge the chasm that is rationally impassable, not only increases the confusion by uniting contradictory THE NERVOUS SYSTEM AND CONSCIOUSNESS. 163 attributes in too small a compass, but it is a pure metaphysical or ontological predication, from which reason defend us ! As to the ex- istence of any Spinozistic substance holding in itself the irreconcilables thought and extension, how can it any longer be worth while to ex- press an opinion ? Perhaps matter is double-faced. This is a specu- lation which, as it transcends, contradicts experience. If I mistake not, Mr. Mill and Mr. Bain have themselves refuted their position with regard to the development of personality from im- personal feeling. Mr. Mill ("Examination of Hamilton," page 242) says : " If, therefore, we speak of the mind as a series of feelings, we are obliged to complete the statement by calling it a series which is aware of itself as past and present ; and we are reduced to the alter- native of believing that the mind or ego is something different from any series of feelings or possibilities of them, or of accepting the para- dox that something which, by hypothesis, is but a series of feelings, can be aware of itself as a series." In his edition of " The Analysis of the Human Mind" (i, 230) he further says, "There is no mean- ing in the word ego, or I, unless the I of to-day is also the I of yester- day." This mast be taken as an admission that personality is an essen- tial for personal identity. Mr. Bain says : " We may be in a state of pleasure with little or nothing of thought " (personal consciousness) " accompanying. We are still properly said to be conscious or under consciousness. It is thus correct to draw a line between feeling and knowing that we feel, although there is great delicacy in the operation. [Italics are the writer's.] It may be said in one sense that we can not feel without knowing that we feel ; but the assertion is verging on error, for a feel- ing may be accompanied with a minimum of cognitive energy or, as good as, none at all." I am unable to appreciate this passage as other than an abandonment of the development theory applied to personality. The language of Professor Calderwood seems just when he writes, " If in every sensation, every feeling, there is a particle of cognitive energy " (if the sensation be known as mine in any sense) " the devel- opment theory as an account of personality fails." Under the influence of the a priori procedure, both metaphysical and theological, most of us flee with raised hands of horror at sound of the word will. Recollections of " you shall and you sha'n't, you can and you can't, you will and you won't," crowd round in ever-thicken- ing confusion. Still, it must be said that, apart from all talk about freedom and bondage, volition is a decidedly large fact in human ex- perience. Though Goethe is right in saying, " Ein kleiner Ring begranzt unser Leben," a ring of circumstance, of inheritance, yet within the circle of that ring a measure of action prevails which no word describes save the word willed. The action is determined by personality. It is impossible to find provision for this in the nervous system. Inhibitory nerves there may be, but the experience of our- 164 THE POPULAR SCIENCE MONTHLY. selves as using within fixed limits this physical organism is an experi- ence too unique to come within nerve-actions and reactions before pleasure and pain. There is no need to multiply illustrations of the exercise of will in holding muscles still against pain or of those higher manifestations where we endure agony, not from any present suffering, but to avoid future loss. In conclusion, and for completeness, reference should be made to the moral consciousness, i. e., the knowledge of obligation. This, too, is a fact in human experience, and as such demands to be traced to its ultimates. A significant thing, from the philosophical side, is Mr. Spencer's anticipatory publication of the " Data of Ethics." By this publication Mr. Spencer has recognized, what many of his smaller adherents fail to know, that, in ethics, as an attempt to give a rational account of the consciousness of obligation, all thinking finds its high- est and most serious application. "We discover in the nervous system no provision for the conscious- ness of duty ; indeed, put in this bald way, no materialist would look there for any such consciousness. Duty as something to be done for its own sake, apart from creed, or sect, or party, or consequences, is properly considered an evidence of culture in thought and action. It is futile to attempt to resist the application of evolution to ethics by any appeal to the transcendent beauty of the moral ideal. The rose is a transcendent thing in color, fragrance, and outline ; still, it de- velops from that which has none of these. Development of some kind is a fact. The stress of inquiry in ethics is, I think, here : Can the sense of right and wrong, however rudimentary, be produced by pains and pleasures ? In the nervous system we have the physical antecedents for pain and pleasure; though no such sensations are in the nervous system, they are in us. Ethics therefore presents the development theory a further difficulty, viz., the one of passing rationally from pains and pleasures to right and wrong. Even Mr. Spencer's form of the development theory, which would seek to find in the conduct called ethical but a part of conduct in general, and to regard all conduct, both ethical and non-ethical, as adjustments of means to ends ; even this form of the theory must be able to make it plain that the transition from conduct non-ethical to conduct ethical is gradual, composed of many steps, and not, as experience seems to teach, sudden, distinct, and sharp. What belief, then, does reason require in our present state of knowl- edge as to the relation between nerve-matter and consciousness ? We distinguish two series, two kinds of experiences ; these stand to one another as outward and inward, physical and spiritual, compound and simple. We do not know the nature of either. The terms matter and soul are our highest generalizations from experience. The materialist errs when he pronounces upon the character of matter, affirming that THE STATE VERSUS THE MAN. 165 in itself, as it lies beyond his vision, it is hard, round, inelastic, double- faced. The spiritualist errs when he pronounces upon the nature of spirit, as it lies beyond his ken, naming it, in essence, immortal, divine. Unity there somehow is in this universe. There are no breaks if we could read aright. Perhaps this reading should see the beginning in the end, not the end in the beginning. The charcoal sketch of Angelo would indeed be promise and potency of greater things, and this because in it was more than charcoal. So it may be well, even rational, to interpret all things and all beings. THE STATE VERSUS THE MAN": A CRITICISM OF MR. HERBERT SPENCER. By EMILE DE LAVELEYE. " La nature est l'injustice meme." — Renan. FOUR articles of Mr. Herbert Spencer's, which appeared in the Contemporary Review, have recently been reprinted together, and form now a work which Mr. Spencer has entitled "The Man versus The State." This little volume merits the most attentive study, because in it the great sociological question of our day is treated in the most masterly manner. The individualist theory was, I think, never expounded better or with stronger arguments based on first principles, or supported by so great a number of clearly analyzed and admirably grouped facts. These pages are also full of important truths and of lessons, from whence both nations and governments may derive great benefit. Mr. Spencer's deductions are so concise and forcible that one feels oneself drawn, against one's will, to accept his conclusions ; and yet, the more I have thought on the subject, the more convinced have I become that these conclusions are not in the true interest of humanity. Mr. Herbert Spencer's object is to prove the error and danger of State socialism, or, in other words, the error and danger of that system which consists in appropriating State, or communal, revenues to the purpose of establishing greater equality among men. The eminent philosopher's statement, that in most civilized coun- tries governments are more and more adopting this course, is indis- putable. In England Parliament is taking the lead ; in Germany Prince Bismarck, in spite of Parliament ; and elsewhere either Parlia- ment or town councils are doing the same thing. Mr. Spencer con- siders that this effort for the improvement of the condition of the working-classes, which is being everywhere made, with greater or less energy, is a violation of natural laws, which will not fail to bring its own punishment on nations, thus misguided by a blind philanthropy. 166 THE POPULAR SCIENCE MONTHLY. I believe, on the contrary, that this effort, taken as a whole, and set- ting aside certain mistaken measures, is not only in strict accordance with the spirit of Christianity, but is also in conformity with the true principles of politics and of political economy. Let us first consider a preliminary question, on which I accept Mr. Spencer's views, but for different reasons from his : On what are indi- vidual rights founded, and what are the limits of State power ? Mr. Spencer refutes with pitiless logic the opinions of those who, with Bentham, maintain that individual rights are State concessions, or who, like Matthew Arnold, deny the existence of natural rights. The absurdity of Bentham's system is palpably evident. Who creates the government ? The people, says he. So the government, thus created, creates rights, and then, having created rights, it confers them on the separate members of the sovereign people, by which it was itself created. The real truth is, that government defines and sanctions rights, and employs the public strength to enforce their being re- spected, but the rights themselves existed before. Referring to the history of all primitive civilization, Mr. Herbert Spencer proves to Mr. Matthew Arnold that in familial and tribal communities there existed certain customs, which conferred recognised and respected rights, before ever any superior authority which could be designated by the name of State had been formed. Only, I think Mr. Herbert Spencer is wrong in making use of the term " natural rights." This expression was an invention of the French philosophers of the eighteenth century, and it is still employed in Germany by a certain school of philosophers as Naturrecht. Sir Henry Maine's clever and just criticism of this expression in his book "Ancient Law" should warn us all of the vague and equivocal meaning it conceals. The jurists and philosophers of the seventeenth and eighteenth cent- uries attached two very different significations to the term " natural rights." They sometimes applied it to the condition of primitive so- cieties, in which their optimism led them to dream of a reign of jus- tice, liberty, and equality, and at other times they made use of it when speaking of the totality of rights which should be possessed by every individual, by reason of his manhood. These two conceptions are equally erroneous. In primitive societies, in spite of certain customs which are the embryo of rights, might reigns supreme, as among ani- mals, and the best armed annihilate their weaker neighbours. Cer- tainly, one would look in vain there for a model of a political constitu- tion or code suitable to a civilized people. Neither can it be main- tained that the " Rights of man," as proclaimed by the American and French Revolutions, belong to each individual, only because he forms part of the human species. The limit of rights which may be claimed by any one individual must depend upon his aptitudes for making good use of them. The same civil code and the same political institu- tions will not equally suit a savage tribe and a civilized nation. If THE STATE VERSUS THE MAN. 167 the granting of the suffrage to all were likely to lead a people to an- archy or to despotism, it could not be called a natural right, for suicide is not a right. If one analyze completely the expression " natural rights," one finds that it is really not sense. Xavier de Maistre, annoyed by the con- stant appeals to nature which are to be found in all the writings of the eighteenth century, said, very wittily : "Nature, who and what is this woman ? " Nature is subject to certain laws, which are invariable ; as, for instance, the law of gravitation. We may call these " laws of nature," but in human institutions, which are ever varying, nothing of the sort can exist. This superior and ideal right, which is invoked for the purjDOse of condemning existing laws, and claiming their reform or suppression, should rather be called rational right — that is to say, right in conformity with reason. In every country, and at all times, an order of things may be con- ceived— civil, political, penal and administrative laws — which would best conform to the general interest, and be the most favourable to the well-being and progress of the nation. This order of things is not the existing one. If it were, one might say, with the optimists, that all is for the best in the best of possible worlds, and a demand for any amelioration would be a rebellion against natural laws, and an absurd- ity. But this order of things may be caught sight of by reason, and defined with more or less accuracy by science ; hence its name of rational order. If I ask for free trade in France, for a better division of property in England, and for greater liberty in Russia, I do so in the name of this rational order, as I believe that these changes would increase men's happiness. This theory permits of our tracing a limit between individual lib- erty and State power. Mr. Herbert Spencer proves very clearly that there are certain things which no man would ever choose to abandon to State power ; his religious convictions, for instance. On the other hand, all would agree that the State should accept the charge of protecting frontiers and punishing theft and murder, that is to say, the maintaining of peace and security at home and abroad ; only here, like most English- men, Mr. Herbert Spencer invokes human will. Find out, he says, on the one hand, what the great majority of mankind would choose to reserve to an individual sphere of action, and, on the other, what they would consent to abandon to State decisions, and you will then be able to fix the limit of the power of public authority. I cannot myself admit that human will is the source of rights. Until quite recently, in all lands, slavery was considered a necessary and legitimate institution. But did this unanimous opinion make it any more a right ? Certainly not. It is in direct opposition to the order of things which would be best for the general welfare ; it can- not, therefore, be a right. 168 THE POPULAR SCIENCE MONTHLY. Until the sixteenth century, with the exception of a few Anabap- tists who were burnt at the stake, all believed that the State ought to punish heretics and atheists. But this general opinion did not suffice to justify the intolerance then practised. The following line of argu- ment, I think, would be most in keeping with individual interests, and, consequently, with the interests of society in general : A certain por- tion of men's acts ought not to be in any way subject to sovereign authority, be it republican or monarchical. But what is to be the boundary of this inviolable domain of individual activity ? The will of the majority, or even of the entire population, is not competent to trace it, for history has proved but too often how gross have been the errors committed in such instances. This limit can, therefore, only be fixed by science, which, at each fresh progress in civilization, can dis- cover and proclaim aloud where State power should cease to interfere. Sociological science, for instance, announces that liberty of conscience should always be respected as man's most sacred possession, and because religious advancement is only to be achieved at this price ; that true property, or, in other words, the fruit of personal labour, must not be tampered with, or labour would be discouraged and production would diminish ; that criminals must not go unpunished, but that justice must be strictly impartial, so that the innocent be not punished with the guilty. It would not be at all impossible to draw up a formula of these essential rights, which M. Thiers called necessary liberties, and which are already inscribed in the constitutions of America, England, France, Belgium, Holland, and all other free nations. It it sometimes very difficult to know where to set bounds to individual liberty, in the in- terests of public order and of the well-being of others ; and it is true, of course, that either the king, the assembly, or the people enacts the requisite laws, but if science has clearly demonstrated a given fact it imposes itself. When certain truths have been frequently and clearly explained, they come to be respected. The evidence of them forms the general opinion, and this engenders laws. To be brief, I agree with Mr. Herbert Spencer that, contrary to Rousseau's doctrine, State power ought to be limited, and that a do- main should be reserved to individual liberty which should be always respected ; but the limits of this domain should be fixed, not by the people, but by reason and science, keeping in view what is best for the public welfare. This brings me to the principal question I desire to treat. I am of opinion that the State should make use of its legitimate powers of action for the establishment of greater equality among men, in pro- portion to their personal merits, and I believe that this would be in conformity, not only with its mission properly speaking, but also with rational rights, with the progress of humanity ; in a word, with all the rights and all the interests invoked by Mr. Herbert Spencer. THE STATE VERSUS THE MAN. 169 I will briefly resume the motives given by Mr. Herbert Spencer to show that any wish to improve the condition of the working-classes by law, or by the action of public power, so as to bring about a greater degree of equality among men, would be to run against the stream of history, and a violation of natural laws. There are, he says, two types of social organization, broadly distinguishable as the " militant " and the "industrial" type. The first of these is characterized by the regime of status, the second by the regime of contract. The latter has become general among modern nations, especially in England and America, whereas the militant type was almost universal formerly. These two types may be defined as the system of compulsory co-opera- tion and the system of voluntary co-operation. The typical structure of the one may be seen in an army formed of conscripts, in which each unit must fulfil commands under pain of death, and receives, in ex- change for his services, food and clothing ; while the typical structure of the other may be seen in a body of workers who agree freely to exchange specified services at a given price, and who are at liberty to separate at will. So long as States are in constant war against each other, governments must perforce be on a military footing, as in an- tiquity. Personal defence, then, being society's great object, it must necessarily give absolute obedience to a chief, as in an army. It is absolutely impossible to unite the blessings of freedom and justice at home with the habitual commission of acts of violence and brutality abroad. Thanks to the almost insensible progress of civilization and to gradual liberal reforms, the ancient militant State was little by little despoiled of its arbitrary powers, the circle of its interventions grew narrower and narrower, and men became free economically, as well as politically. We were advancing rapidly towards an industrial regime of free contract. But, recently, the Liberals in all countries have adopted an entirely opjDOsite course. Instead of restricting the powers of the State, they are extending them, and this leads to socialism, the ideal of which is to give to government the direction of all social ac- tivity. Men imagine that, by thus acting, they are consulting the interests of the working-classes. They believe that a remedy may be found for the sufferings which result from the present order of things, and that it is the State's mission to discover and apply that remedy. By thus acting they simply increase the evils they would fain cure, and prepare the way for a universal bondage, which awaits us all — the Coming Slavery. Be the authority exercised by king, assembly, or people, I am none the less a slave if I am forced to obey in all things, and to give up to others the net produce of my labour. Contemporary progressism not only runs against the stream of history, by carrying us back to despotic organizations of the militant system, but it also violates natural laws, and thus prepares the degeneration of humanity. In family life the gratuitous parental aid must be great in proportion 170 THE POPULAR SCIENCE MONTHLY. as the young one is of little "worth either to itself or to others, and benefits received must be inversely as the power or ability of the re- ceiver. " Throughout the rest of its life each adult gets benefit in proportion to merit, reward in proportion to desert, merit and desert being understood as ability to fulfil all the requirements of life. Placed in competition with members of its own species, and in antagonism wTith members of other species, it dwindles and gets killed off, or thrives and propagates, according as it is ill-endowed or well- endowed. If the benefits received by each individual were proportionate to its inferiority, if, as a consequence, multiplication of the inferior was furthered and multiplication of the superior hindered, progressive degradation would result, and eventually the degenerated species would fail to hold its ground in presence of antagonistic species and competing species." (Page 65.) "The poverty of the incapable, the distress that comes upon the imprudent, the starvation of the idle, and the shouldering aside of the weak by the strong, which leave so many ' in shallows and in miseries,' are the decrees of a large, far-seeing benevolence." (Page 67.) When the State, guided by a wrongly inspired philanthropy, pre- vents the application of this wise law, instead of diminishing suffering it increases it. " It tends to fill the world with those to whom life will bring most pain, and tends to keep out of it those to whom life will bring most pleasure. It inflicts positive misery, and prevents posi- tive happiness." ("Social Statics," p. 381, edit. 1851.) The law that Mr. Herbert Spencer desires society to adopt is sim- ply Darwin's law — " the survival of the fittest." Mr. Spencer expresses his astonishment that at the present day, more than at any other period of the world's history, everything is done to favour the survival of the unfittest, when, at the same time, the truth as revealed by Dar- win, is admitted and accepted by an ever-growing number of educated and influential people ! I have endeavoured to give a brief sketch of the line of argument followed by Mr. Herbert Spencer. We will now see what reply can be made to it. I think one chief point ought not to have escaped the eminent writer. It is this : If the application of the Darwinian law to the government of societies be really justifiable, is it not strange that public opinion, not only in England, but in all other countries, is so strenuously opposed to it, at an epoch which is be- coming more and more enlightened, and when sociological studies are pursued with so much interest? If the intervention of public power for the improvement of the condition of the working-classes be a contradiction of history, and a return to ancient militant society, how is it that the country in which the new industrial organiza- tion is the most developed — that is to say, England — is also the country where State intervention is the most rapidly increasing, and where opinion is at the same time pressing for these powers of inter- ference to be still further extended ? There is no other land in which THE STATE VERSUS THE MAN. i7i the effort to succour outcasts and the needy poor occupies so large a portion of the time and means of the well-to-do and of the public exchequer ; there is nowhere else to be found a poor-law which grants assistance to even able-bodied men ; nowhere else would it ever have been even suggested to attack free contract, and consequently the very first principles of proprietorship, as the Irish Land Bill has done ; and nowhere else would a Minister have dared to draw up a programme of reforms such as those announced by Mr. Chamberlain at the Liberal Reform Club at Ipswich (Jan. 14, 1885). On the Continent all this would be looked upon as rank socialism. If, then, as a country be- comes more civilized and enlightened it shows more inclination to return to what Mr. Herbert Spencer calls militant organization, and to violate the Darwinian law applied to human society, may we not be led to conclude that this so-called retrogression is really progress ? This conclusion would very easily explain what Mr. Herbert Spencer designates as the "wheeling round" of the Liberal party with which he so eloquently reproaches them. Why did the Liberals formerly do their utmost to restrict State power? Because this power was then exercised in the interests of the upper classes and to the detriment of the lower. To mention but one example : When, in former times, it was desired to fix a scale of prices and wages, it was with a view to preventing their being raised, while, to-day, there is a clamour for a lessening of hours of labour with increased remuneration. Why do Liberals now wish to add to the power and authority of the State ? To be able to amelio- rate the intellectual, moral, and material condition of a greater number of citizens. There is no inconsistency in their programme ; the ob- ject in view, which is the great aim of all civilization, has been always the same — to assure to each individual liberty and well-being in pro- portion to his merit and activity ! I think that the great fundamental error of Mr. Herbert Spencer's system, which is so generally accepted at the present day, consists in the belief that if State power were but sufficiently reduced to narrow it to the circle traced by orthodox economists, the Darwinian law and the survival of the fittest would naturally follow without difficulty. Mr. Spencer has simply borrowed from old-fashioned political economy, without submitting to the fire of his inexorable criticism, the super- ficial and false notion that, if the laissez-faire and free contract regime were proclaimed, the so-called natural laws would govern the social order. He forgets that all individual activity is accomplished under the empire of laws, which enact as to ownership, hereditary succes- sion, mutual obligations, trade and industry, political institutions and administrations, besides a multitude of laws referring to material interests, banking organizations, money, credit, colonies, army, navy, railways, etc. For natural laws, and especially the law of the survival of the fittest, 172 THE POPULAR SCIENCE MONTHLY to become established, it would be necessary to annihilate the immense existing edifice of legislation, and to return to the wild state of society when primitive men lived, in all probability, much as do animals, with no possessions, no successions, no protection of the weak by the State. Those who, with Mr. Spencer and Haeckel and other Conserva- tive evolutionists, are anxious to see the law of the survival of the fittest and of natural selection adopted in human society, do not realize that the animal kingdom and social organization are two such totally different domains that the same law, applied to each, would produce wholly opposite effects. Mr. Herbert Spencer gives an admi- rable description of the manner in which natural selection is accom- plished among animals : — " Their carnivorous enemies not only remove from herbivorous herds indi- viduals past their prime, hut also weed out the sickly, the malformed, and the least fleet and powerful. By the aid of which purifying process, as well as by the fighting so universal in the pairing season, all vitiation of the race through the multiplication of its inferior samples is prevented, and the maintenance of a constitution completely adapted to surrounding conditions, and therefore most productive of happiness, is ensured." This is the ideal order of things which, we are told, ought to pre- vail in human societies, but everything in our present organization (which economists, and even Mr. Spencer himself, admit, however, to be natural) is wholly opposed to any such conditions. An old and sickly lion captured a gazelle ; his younger and stronger brother ai-rives, snatches away his prize, and lives to perpetuate the species ; the old one dies in the struggle, or is starved to death. Such is the beneficent law of the "survival of the fittest." It was thus among barbarian tribes. But could such a law exist in our present social order ? Certainly not ! The rich man, feebly constituted and sickly, protected by the law, enjoys his wealth, marries and has offspring, and if an Apollo of herculean strength attempted to take from him his possessions, or his wife, he would be thrown into prison, and were he to attempt to practise the Darwinian law of selection, he would cer- tainly run a fair risk of the gallows, for this law may be briefly ex- pressed as follows : Room for the mighty, for might is right. It will be objected that in industrial societies the quality the most de- serving of recompense, and which indeed receives the most frequent reward, is not the talent of killing one's fellow-man, but an aptitude for labour and producing. But at the present time is this really so ? Stuart Mill says that from the top to the bottom of the social ladder remuneration lessens as the work accomplished increases. I admit that this statement may be somewhat exaggerated, but, I think, no one will deny that it contains a large amount of truth. Let us but cast our eyes around us, and we see everywhere those who do nothing living in ease and even opulence, while the workers who have the THE STATE VERSUS THE MAN. 173 hardest labour to perform, who toil from night to morning in mines, or unhealthy workshops, or on the sea in tempests, in constant danger of death, are paid, in exchange for all these hardships, a salary hardly sufficient for their means of subsistence, and which, just now, has be- come smaller and smaller, in consequence of the ever-recurring strikes, and the necessary closing of so many factories, mines, etc., owing to the long-continued depression of trade. What rapid fortunes have been made by stock-broking manoeuvres, by trickeries in supplying goods, by sending unseaworthy vessels to sea to become the coffins of their crews ! Do not such sights as these urge the partisans of prog- ress to demand the State's interference in favour of the classes who receive so inadequate a payment for their labours ? The economists of the old school promised that, if the laissez-faire and free contract regime were proclaimed, justice would reign uni- versally ; but when people saw that these fine promises were not real- ized, they had recourse to public power for the obtaining of those re- sults which the much-boasted " liberty " had not secured. The system of accumulating wealth and hereditary succession alone would suffice to prevent the Darwinian law ever gaining a footing in civilized communities. Among animals, the survival of the fittest takes place quite naturally, because, as generations succeed each other, each one must create his own position according to his strength and abilities ; and in this way the purifying process, which Mr. Herbert Spencer so extols, is effected. A similar system was generally preva- lent among barbarians ; but, at the present day, traces of it may be seen only in instances of " self-made men ; " it disappears in their chil- dren, who, even if they inherit their parents' talents and capacities, are brought uj), as a rule, in so much ease and luxury that the germs of such talents are destroyed. Their lot in life is assured to them, so why need they exert themselves ? Thus they fail to cultivate the qualities and tastes they may have inherited from their parents, and they and their descendants become in all points inferior to their ances- tors who secured to them, by labour and industry, the privileged posi- tion they hold. Hence the proverb, A pere econome fits prodigue (To a thrifty father, a spendthrift son). It follows, therefore, that those who wish to see the law of natu- ral selection, by the transmission of hereditary aptitudes, established amongst us should begin by demanding the abolition of hereditary succession. Among animals, the vitiation of the race through the multiplica- tion of its inferior samples is prevented " by the fighting so universal in the pairing season." In the social order the accumulation and hereditary transmission of wealth effectually impede the process of perfecting the race. In Greece after the athletic sports, or in those fortunate and chimerical days of which the Troubadours sang, " the most beautiful was sometimes given as a prize to the most valiant ; " i74 THE POPULAR SCIENCE MONTHLY. but, in our prosaic age, rank and fortune too often triumph over beau- ty, strength, and health. In the animal world, the destiny of each one is decided by its personal qualities. In society, a man attains a high position, or marries a beautiful woman, because he is of high birth, or wealthy, although he may be ugly, lazy, and extravagant. The per- manent army and the navy would also have to be destroyed, before the Darwinian law could triumph. Conscription on the Continent and enlistment in England (to a less degree) condemn many of the strong- est and most warlike men to enforced celibacy ; and, as they are sub- jected to exceptional dangers in the way of hazardous expeditions and wars, the death-rate is far higher amongst them than it would be under ordinary circumstances. In pre-historic times, or in a general way, such men would certainly have begotten offspring, as being the strongest and most apt to survive ; in our societies, they are decimated or condemned to celibacy. Having borrowed from orthodox political economy the notion that it would suffice to put a check on inopportune State intervention for the reign of justice to become established, Mr. Herbert Spencer pro- ceeds to demonstrate that the legislators who enacted the poor-law, and all recent and present law-makers " who have made regulations which have brought into being a permanent body of tramps, who ramble from union to union, and which maintain a constant supply of felons by sending back convicts into society under such conditions that they are almost compelled again to commit crimes," are alone responsible for the sufferings of the working-classes. But may we not blame law-makers, or, rather, our own social order, for measures more fatal in their results than either of these — for instance, the law which concentrates all property into the hands of a few owners? Some years ago, Mr. Herbert Spencer wrote some lines on this sub- ject which are the most severe indictment against the present social order that has ever fallen from the pen of a really competent writer : — " Given a race of beings having like claims to pursue the objects of their desires — given a world adapted to the gratification of those desires — a world into which such beings are similarly born, and it unavoidably follows that they have equal rights to the use of this world. For if each of them 'has freedom to do all tbat he wills, provided he infringes not the equal freedom of any other,' then each of them is free to use the earth for the satisfaction of his wants, pro- vided he allows all others the same liberty. And, conversely, it is manifest that no one or part of them may use the earth in such a way as to prevent the rest from similarly using it, seeing that to do this is to assume greater freedom than the rest, and, consequently, to break the law. Equity, therefore, does not per- mit property in land. On examination, all existing titles to such property turn out to be invalid ; those founded on reclamation inclusive. It appears that not even an equal apportionment of the earth amongst its inhabitants could generate a legitimate proprietorship. "We find that, if pushed to its ultimate consequences, a claim to exclusive possession of the soil involves a land-owning despotism. We THE STATE VERSUS THE MAN. 175 further find that such a claim is constantly denied by the enactments of our legis- lature. And we find, lastly, that the theory of the co-heirship of all men to the soil is consistent with the highest civilization ; and that, however difficult it may be to embody that theory in fact, equity sternly commands it to be done." " By- and-by, men may learn that to deprive others of their rights to the use of the earth is to commit a crime inferior only in wickedness to the crime of taking away their lives or personal liberties." (" Social Statics," chap, ix.) Has Mr. Herbert Spencer changed his opinions as to the proprie- torship of the soil since these lines were written? Not at all, for, in the chapter entitled " The Coming Slavery," he writes that " the movement for land-nationalization is aiming at a system of land-tenure equitable in the abstract." But if society, in depriving numbers of persons of their right of co-heirship of the soil, has " committed a crime inferior only in wickedness to the crime of taking away their lives or personal liberties," ought it not, in common justice, to en- deavour to repair the injury done ? The help given by public assist- ance compensates very feebly for the advantages they are deprived of. In his important book, " La Propriete Sociale," M. Alfred Fouillee, examining the question from another standpoint, very accurately calls this assistance " la justice reparative." The numerous and admirable charitable organizations which exist in England, the keen emotion and deep commiseration manifested when the little pamphlet, " The Bitter Cry of Outcast London," was first published, the growing pre-occupa- tion of Government with the condition of the working-classes, must be attributed, in the first instance certainly to Christian feeling, but also, in a great measure, to a clearer perception of certain ill-defined rights possessed by those who have been kept deprived of national or rather communal co-heirship. Mr. Herbert Spencer has expressed this idea so clearly and eloquently that I hope I may be allowed to quote the passage : — " We must not overlook the fact that, erroneous as are these poor-law and communist theories, these assertions of a man's right to maintenance and of his right to have work provided for him, they are nevertheless nearly related to a truth. They are unsuccessful efforts to express the fact that whoso is born on this planet of ours thereby obtains some interest in it — may not be summarily dismissed again — may not have his existence ignored by those in possession. In other words, they are attempts to embody that thought which finds its legiti- mate utterance in the law: All men have equal rights to the use of the earth. . . . After getting from under the grosser injustice of slavery, men could not help beginning in course of time to feel what a monstrous thing it was that nine people out of ten should live in the world on sufferance, not having even stand- ing room save by allowance of those who claim the earth's surface." (" Social Statics," p. 345.) When one reads through that substantial essay, " The Man versus The State," it appears as if the principal or, indeed, the sole aim of State socialism were the extension of public assistance and increased 176 THE POPULAR SCIENCE MONTHLY. succour for the unworthy, whereas the reality is quite the reverse of this ! Scientific socialism seeks, first of all, the means of so raising the working-classes that they may be better able to maintain them- selves and, consequently, to dispense with the help of others ; and, secondly, it seeks to find what laws are the most in conformity with absolute justice, and with that admirable precept, " Benefit in propor- tion to merit, reward in proportion to desert." In the speech deliv- ered by Mr. Shaw Lefevre, last year (1884), as President of the Con- gress of Social Science, at its opening meeting at Birmingham, he traced, in most striking language, all the good that State intervention had effected in England of late yeai-s : Greater justice enforced in the relations between man and man, children better educated and better prepared to become useful and self-supporting members of the com- munity, the farmer better guaranteed against the exaggerated or un- just demands of the proprietor, greater facilities for saving offered, health ensured to future generations by the hours of labour being lim- ited, the lives of miners further safeguarded, so that there are less fre- quent appeals to public assistance, and, as a practical result of this last measure, the mortality in mines fallen in the last three years to 22-l per thousand, as compared to 27'2 per thousand during the ten previous years — a decrease of 20 per cent. ! One fact is sufficient to show the great progress due to this State legislation : in an ever-increasing popu- lation, crime is rapidly and greatly diminishing. Suppose that, through making better laws, men arrive gradually at the condition of the Norwegian peasantry, or at an organization simi- lar to that existing in the agricultural cantons of Switzerland ; that is to say, that each family living in the country has a plot of ground to cultivate and a house to live in : in this case every one is allowed to enjoy the full fruit of his labour, and receives reward in proportion to his activity and industry, which is certainly the very ideal of jus- tice— cuique suum. The true instinct of humanity has ever so understood social organ- ization that property is the indispensable basis of the family, and a necessary condition of freedom. To prevent any one individual from being deprived of a share in the soil, which was in primitive ages con- sidered to be the collective property of the tribe, it was subjected to periodical divisions ; these, indeed, still take place in the Swiss All- mend, in some Scottish townships, in the greater part of Java, and in the Russian Mir. If such a regime as this were established, there would be no more " tramps wandering from union to union." In such a state of society as this, not in such as ours, the supreme law which ought to govern all economic relations might be realized. Mr. Herbert Spencer admirably defines this law in the following passage : — " I suppose a dictum on which the current creed and the creed of science are at one may be considered to have as high an authority as can be found. Well, THE STATE VERSUS THE MAN. 177 the command, If any would not work, neither should he eat, is simply a Christian enunciation of that universal law of nature under which life has reached its present height, the law that a creature not energetic enough to maintain itself must die; the sole difference being, that the law which in one case is to be arti- ficially enforced is in the other case a natural necessity." This passage ought to be transcribed at the commencement of every treatise on social science as the supreme aim of all sociological research ; only the delusion, borrowed from the old political economy, which consists in the belief that this dictum of science and Christian- ity is in practice in our midst, ought to be suppressed. Is it not a fact that, everywhere, those who can prove by authentic documents that, for centuries past, their ancestors have thriven in idle- ness are the richest, the most powerful, the most sought after ? Only at some future date will this dictum of science and Christianity be brought to bear on our social organization, and our descendants will then establish an order of things which will create economic respon- sibility, and ensure to each the integral enjoyment of the produce of his labour. The difficult but necessary work of sociology is to en- deavour to discover what this organization should be, and to prepare its advent. Mr. Shaw Lefevre's speech shows very clearly the road that ouerht to be taken. Mr. Herbert Spencer thinks, however, that this road would lead us directly to a condition of universal slavery. The State would gradu- ally monopolize all industrial enterprises, beginning with the railways and telegraphs as it has already done in Germany and Belgium, then some other industries as in France, then mines, and finally, after the nationalization of land, it would also take up agricultural enterprise. The freedom enjoyed by a citizen must be measured, he says, not by the nature of the government under which he lives, but by the small number of laws to which he is subject. The essential characteristic of the slave is that he is forced to work for another's benefit. The de- gree of his slavery varies according to the greater or smaller extent to which effort is compulsorily expended for the benefit of anotherr in- stead of for self -benefit ; in the regime which is approaching, man will have to work for the State, and to give up to it the largest portion of his produce. What matters it that the master under whose command he labours is not an individual, but society ? Thus argues Mr. Herbert Spencer. In my opinion, the State will never arrive at a monopoly of" all in- dustries, for the very simple reason that such a system would never answer. It is possible that some day a social organization such as M. Albert Schaffle, formerly Finance Minister in Austria, has explained, may grow up, in which all branches of production are placed in the hands of co-operative societies. But, be that as it may, men would be no more slaves in workshops belonging to the State than in those of merchants or manufacturers of the present day. Mr„ Herbert Spencer VOL. XXVII. — 12 178 THE POPULAR SCIENCE MONTHLY. can very easily assure himself of this fact. Let him visit the State collieries at Saarbruck, or inspect the Belgian railways, and interrogate all the officials and workmen employed ; he will find that, from the highest to the lowest, they are quite as free, quite as contented with their lot, as those engaged in any private industry. There is even far more guarantee against arbitrary measures, so that their real freedom is greater than elsewhere. The proof of this is the fact that posts in any industries belonging to the State are always sought for by the best workmen. If the degree of man's slavery varies according to the ratio between that which he is forced to yield up and that which he is allowed to retain, then it must be admitted that the majority of work- men and small farmers are certainly slaves now, for they have very little or no property, and, as their condition almost entirely depends on the hard law of competition, they can only retain for themselves the mere necessaries of life ! Are the Italian contadini, whose sad lot I depicted in my " Lettres d'ltalie," free ? They are reduced to live entirely on bad maize, which subjects them to that terrible scourge, the pellagra. What sad truth is contained in their reply to the Minis- ter who advised them not to emigrate ! — "What do you mean by the nation? Do you refer to the most miserable of the inhabitants of the land? If so, we are indeed the nation. Look at our pale and emaciated faces, our bodies worn out with over-fatigue and insufficient food. We sow and reap corn, but never taste white bread ; we cultivate the vine, but a drop of wine never touches our lips. We raise cattle, but never eat meat ; we are covered with rags, we live in wretched hovels ; in winter we suffer from the cold, and both winter and summer from the pangs of hunger. Can a land which does not provide its inhabitants, who are willing to work, with sufficient to live upon, be considered by them as a fatherland? " The Flemish agricultural labourer, who earns less than a shilling a day, and the small farmer, whose rack-rent absorbs the entire net profits ; the Highland crofters, who have been deprived of the com- munal land, the sacred inheritance of primitive times, where they could at least raise a few head of cattle ; the Egyptian fellahs, whose very life-blood is drained by European creditors — in a word, all the wretched beings all over the world where the soil is owned by non-workers, and who labour for insufficient remuneration ; can they, any of them, be called free? It is just possible that, if the State were to become the universal industry director (which, in my opinion, is an impossible hj- pothesis), their condition would not be improved ; but at all events it could not be worse than it is now. I do not believe that " liberty must be surrendered in proportion as the material welfare is cared for." On the contrary, a certain degree of well-being is a necessary condition of liberty. It is a mockery to call a man free who, by labour, cannot secure to himself the necessaries of existence, or to whom labour is impossible because he possesses nothing of his own, and no one will employ him ! THE STATE VERSUS THE MAN. i79 Compare the life of the soldier with that of the hired workman either in a mine or a factory. The first is the type of the serf in " The Coming Slavery," and the second the type of the independent man in an industrial organization under the free contract regime. Which of the two possesses the most real liberty ? The soldier, when his daily duties are accomplished, may read, walk, or enjoy himself in accordance with his tastes ; the woi'kman, when he returns home worn out with fatigue after eleven or twelve hours' hard labour, too often finds no other recreation than the gin-palace. The labourer at his task must always, and all day long, obey the foreman or overseer, whether he be employed by a private individual, by the State, or by a co-operative society. "Hitherto," says Mr. Herbert Spencer, "you have been free to spend your earnings in any way which pleases you ; hereafter you shall not be free to spend it, but it will be spent for the general bene- fit." The important point, he adds, is the amount taken from me, not the hand that takes it. But if what is taken from my revenue is em- ployed to make a public park which I am free to enter whenever I feel inclined, to build public baths where I may bathe in summer or winter, to open libraries for my recreation and instruction, clubs where I may spend my evenings, and schools where my children may receive an education which will enable them to make their own way in the world ; to build healthy houses, let at a low rent, which save me the cruel necessity of living in slums, where the soul and the body are alike degraded ; if all this be done, would the result be the same as if this sum were taken by some private Croesus to spend on his personal pleasures and caprices ? In the course of last summer, while in Switzerland and Baden, I visited several villages where each family is supplied, from forests belonging to the commune, with wood for building purposes and for fuel ; also with pasturage for their cattle, and with a small plot of ground on which to grow potatoes, fruit, and vegetables. In addition to this, the wages of aH public servants are paid for from the communal revenue, so that there is no local taxation whatever.* Suppose that these woods and meadows, and this land, * I may mention as an example, the township of Freudenstadt, at the foot of the Kniebis, in Baden. Not a single farthing of taxation has been paid since its foundation in 1557. The commune possesses about 5,000 acres of pine-forest and meadow-land, worth about £10,000 sterling. The 1,420 inhabitants have each as much wood for their building purposes and firing as they wish for, and each one can send out to pasture, during the summer, his cattle, which he feeds during the winter months. The schools, church, thoroughfares, and fountains are all w^ell cared for, and every year considerable improvements are made. 100,000 marks were employed in 1883 for the establishment in the village, of a distribution of water, with iron pipes. A hospital has been built, and a pavilion in the market-place, where a band plays on fete-days. Each year a distribu- tion of the surplus revenue is made amongst the families, and they each obtain from 50 to 60 marks, or shillings, and more still when an extraordinary quantity of timber has been sold. In 1882, 80,000 marks were distributed amongst the 1,420 villagers. What a favoured country, is it not ? 180 THE POPULAR SCIENCE MONTHLY. all belonged to a landed proprietor, instead of to the commune ; he would go and lavish the revenue in large capitals or in travelling. What an immense difference this would make to the inhabitants ! To appreciate this, it suffices merely to comjjare the condition of the Highland crofters, the free citizens of one of the richest countries in the world, and whose race has ever been laborious, with that of the population of these villages, hidden away in the Alpine cantons of Switzerland or in the gorges of the Black Forest. If, in the High- land villages of Scotland, rentals had been, as in these happy com- munes of Switzerland and Baden, partly reserved for the inhabitants, and partly employed in objects of general utility, how very different would have been the lot of these poor people ! Had they but been allowed to keep for themselves the sea-weed and the kelp which the sea brings them, how far better off would they have been than they now are, as is admirably proved in Mr. Blackie's interesting book, " The Scottish Highlanders." A similar remark may also be applied to politics. What matters it, says Mr. Herbert Spencer, that I myself contribute to make laws if these laws deprive me of my liberty ? He mentions ancient Greece as an example to startle us at the notion of our coming state of slav- ery. He writes : " In ancient Greece the accepted principle was, that the citizen belonged neither to himself nor to his family, but to his city — the city being, with the Greek, equivalent to the community. And this doctrine, proper to a state of constant warfare, is one which socialism unawares re-introduces into a state intended to be purely industrial." It is perfectly certain that the regime of ancient Greek cities, which was founded on slavery, cannot be suitable to modern society, which is based on a system of labour. But we must not allow ourselves to forget what Greece was, nor all we owe to that Greek civilization, which, Mr. Herbert Spencer says, the " coming slavery " threatens to re-introduce amongst us. Not only philosophy, literature, and arts flourished as they have never done in any other age, but the political system so stamped characters with individuality that the illustrious men of Greece are types of human greatness, whose deeds and sayings will be engraven on the memory of men so long as the world lasts. If the " coming slavery " gives us such men as Pisistra- tus, Plato, Aristotle, Xenophon, Lycurgus, Sophocles, Thucydides, Epaminondas, Aristides, or Pericles, we shall, I think, have no cause to complain ! But how is it that Greece produced such a bevy of great men ? By her democratic institutions, combined with a marvel- lous system of education, which developed simultaneously the faculties of the mind and the body. The German army, in spite of its iron discipline, arrives at results somewhat similar, though in a less degree. A rough peasant joins a regiment ; he is taught to walk properly, to swim, and to shift for himself ; his education is made more complete, and he becomes a man THE STATE VERSUS THE MAN. 181 of independent character, better fitted to survive in the struggle for life. If the authorities in towns levy heavy taxes, and employ the money in improving the condition of the inhabitants and in forming those who need forming, even more than in the German army, and after the fashion of the ancient Greeks, will not the generations yet to come be better able to earn their own livelihood, and to maintain an honourable position, than if they had been allowed to pass their child- hood in the gutters ? Mr. Herbert Spencer reasons falsely when he says, " What matters it that I make the laws if these lawTs deprive me of my liberty ? " Laws which tax me to degrade and rob me are odious, but laws which deprive me of what I have for my own good and for the further development of my faculties are well-meaning, as is the constraint imposed on his children by a wise father for their instruction or correction. Besides, to contribute to make laws ele- vates a man's character. As Stuart Mill has proved, this is indeed one of the great advantages of an extension of the suffrage. A man called upon to vote is naturally raised from the sphere of personal to that of general interests. He will read, discuss, and endeavour to obtain in- formation. Others will argue with him, try to change his opinions, and he will himself realize that he has a certain importance of his own, that he has a word to say in the direction of public affairs. The ele- vating influence of this sentiment over French, and still more over Swiss, citizens is remarkable. It is perfectly true that, for political and social reforms to be pro- ductive of fruits, the society into which they are introduced must be in a sufficiently advanced condition to be able to understand and apply them, but it must not be forgotten that improved institutions make better men. Go to Norway ; crimes are hardly known there. In the country people never close their doors at night, locks and bolts are scarcely known, and there are no robberies ; probably, first, because the people are moral and religious, but certainly, also, because property is very equally divided. None live in opulence and none in absolute beggary, and certainly misery and degradation, which often results from misery, are the causes of the great majority of crimes. The rich financier, Helvetius, wrote, very truly, that, if every citi- zen were an owner of property, the general tone of the nation would be conservative, but if the majority have nothing, robbery then be- comes the general aim. ("De l'Homme," sect. vi. chap, vii.) In conclusion, let us try to go to the root of the matter. Two sys- tems are suggested as cures for the evils under which society is suf- fering. On the one hand, it may be said, in accordance with the doctrines of Christianity and socialism, that these evils are the conse- quences of men's perversity and selfishness, and that it behoves charity and fraternity to remedy them. We must do our best to assist our unfortunate brethren. But how ? By trying, Christ tells us, to imi- 182 THE POPULAR SCIENCE MONTHLY. tate God's Kingdom, where " the last shall be first and the first last ; " — or by " having all things in common," say the Apostles in all the ardour of primitive Christianity, and later on certain religious com- munities ; — or by the giving of alms and other charitable acts, says the Christianity of the middle ages ; — while socialism maintains that this may be effected by reforms in the laws regulating the division of property. On the other hand, political economy and evolutionary sociology teach us that these miseries are the inevitable and beneficent consequences of natural laws ; that these laws, being necessary condi- tions of progress, any endeavour to do away with them would be to disturb the order of nature and delay the dawn of better things. By " the weeding out of the sickly and infirm," and the survival of the fittest, the process of amelioration of species in the animal kingdom is accomplished. This law of natural selection should be allowed free and ample scope in human society. " Society is not a manufacture, but a growth." Might is really right, for it is to the general interest that the mighty should triumph and perpetuate the race. Thus argues what is now called Science. In a book entitled " The True History of Joshua Davidson," the author places ideal Christianity and contemporary society face to face, and shows very clearly the opposition which exists between the doc- trines of would-be science and those of the Gospel : — " If the dogmas of political economy are really exact, if the laws of the struggle for life and the survival of the fittest must really be applied to human society, as well as to plants and animals, then let us at once admit that Chris- tianity, which gives assistance to the poor and needy, and which stretches out a hand to the sinner, is a mere folly; and let us at once abandon a belief which influences neither our political institutions nor our social arrangements, and which ought not to influence them. If Christ was right, then our present Chris- tianity is wrong, and if sociology really contains scientific truth, then Jesus of Nazareth spoke and acted in vain, or rather He rebelled against the immutable laws of nature." (Tauchnitz edition, p. 252.) Mr. William Graham, in his " Creed of Science " (p. 278), writes as follows : — " This great and far-reaching controversy, the most important in the history of our species, which is probably as old as human society itself, and certainly as old as the ' Republic ' of Plato, in which it is discussed, or as Christianity, which began with a communistic form of society, had yet only within the past half century come to be felt as a controversy involving real and living issues of a momentous character, and not Utopias only remotely bordering upon the possible." I think it may be proved that this so-called "doctrine of science" is contrary to facts, and is, consequently, not scientific ; whereas the creed of Christianity is in keeping with both present facts and ideal humanity. Darwin borrowed his idea of the struggle for existence and the THE STATE VERSUS THE MAN. 183 survival of the fittest from Malthus, from whom he also drew his theories of evolution and of transformism ; but no naturalist ever dreamt of applying either of these laws to human society. It has been reserved to sociology to attempt this, because it has accepted, blindfolded, from the hands of economists, this most erroneous prin- ciple : that society is governed by natural laws, and that it suffices to give them free scope for the greatest possible happiness and pros- perity to reign. It is manifestly true that, as human society is com- prehended in what we call Nature, it must obey her laws ; but the laws and institutions, in all their different forms, which decree as to the acquisition and transmission of property or possessions, and heredi- tary succession, in a word, all civil and penal laws, emanate from men's will, and from the decisions of legislators ; and if experience, or a higher conception of justice, shows us that these laws are bad, or in any way lacking, we are free to change them. As far as the Darwinian laws are concerned, it would be perfectly impossible to apply them to existing society without more radically destroying all established institutions than the most avowed Nihilist would wish to do. If it be really advisable that the law of the " survival of the fittest " should be established amongst us, the first step to be taken would be the abolition of all laws which punish theft and murder. Animals provide themselves with food by physical activity and the use of their muscles. Among men, in consequence of successive institutions, such as slavery, servitude, and revenue, numbers of people now live in plenty on their income, and do nothing at all. If Mr. Herbert Spencer is really desirous to see the supreme principle, " reward in proportion to desert," in force amongst us, he must obtain, first of all, the suppres- sion of the existing regulations as to property. In the animal world, the destiny of each is decided by its aptitudes. Among ourselves, the destiny of each is determined by the advantages obtained or inherited from parents, and the heir to, or owner of, a large estate is sure to be well received everywhere. We see then, that before Darwinian laws can become established, family succession must be abolished. Ani- mals, like plants, obey the instincts of nature, and reproduce themselves rapidly ; but incessant carnage prevents their too excessive multiplica- tion ! As men become more civilized, peace becomes more general ; they talk of their fellow-men as their brothers, and some philosophers even dream — the madmen ! — of arbitration supplanting war ! The equilibrium between the births and the deaths is thus upset ! To bal- ance it again, let us glorify battles, asd exclaim, with General Moltke, that the idea of suppressing them is a mischievous Utopia ; let us im- pose silence on those dangerous fanatics who repeat incessantly, " Peace on earth, good will towards men." In the very heart of nature reigns seeming injustice ; or, as M. Renan puts it more strongly, nature is the embodiment of injustice. 184 THE POPULAR SCIENCE MONTHLY. A falling stone crushes both the honest man and the scamp ! A bird goes out to find food for its young, and after long search is returning to its nest with its well-earned gains, when an eagle, the despot of the air, swoops down and steals the food ; we think this iniquitous and odious, and would not tolerate such an instance amongst us. Vigorous Cain kills gentle Abel. Right and justice protest. They should not do so, for it is the mere putting in practice " of the purifying process by which nature weeds out the least powerful and prevents the vitiation of the race by the multiplication of its inferior samples." Helvetius admirably defines, for its condemnation, this Darwinian law which Herbert Spencer would have society accept : — "The savage says to those who are weaker than himself: Look up to the skies and you see the eagle swooping down on the dove ; cast your eyes on the earth and you see the lion tearing to pieces the stag or the antelope ; while in the depths of the ocean small fishes are destroyed hy sharks. The whole of nature announces that the weak must be the prey of the strong. Strength is a gift of the gods. Through it I become possessor of all it is in my power to cap- ture." ("De l'Homme," iv. 8.) The constant effort of moralists and legislators has been to replace the reign of might by a reign of justice. As Bacon says, In socie- tate aut vis end lex viget. The object is to subject men's actions more and more to the empire of the law, and that the law should be more and more in conformity with equity. Society has ever been, and still is, to a great extent, too much a reflection of nature. Violations of justice are numerous, and, if these are to be put a stop to, we must oppose ourselves still more to the laws of nature, instead of contem- plating their re-establishment. This is why Christianity, which is an ardent aspiration after jus- tice, is in real accordance with true science. In the book of Job the problem is tragically proposed. The unjust are equally happy with the just, and, as in nature, the strong live at the cost of the weak. Right protests against this, and the voice of the poor is raised against their oppressors. Listen. What deep thought is contained in the follow- ing passage ! — " Wherefore do the wicked live, become old, yea, are mighty in power ? Their seed is established in their sight with them, and their offspring before their eyes. Their houses are safe from fear, neither is the rod of God upon them." (Job xxi. 7-9). " Some remove land-marks ; they violently take away flocks and feed thereof. They cause him to go naked without clothing, and they take away the sheaf from the hungry ; which make oil within their walls, and tread their wine-presses, and suffer thirst" (Job xxiv. 2, 10, 11). The prophets of Israel raised an eloquent protest against the evils then reigning in society, and announced that a time should come when justice would be established upon the earth. These hopes of a Mes- siah were expressed in such precise terms that they may serve as a THE STATE VERSUS THE MAN. 185 programme of the reforms which yet remain to he accomplished. " He shall judge the poor of the people, He shall save the children of the needy, and shall break in pieces the oppressor. He shall spare the poor and needy, and shall save the souls of the needy. There shall be an handful of corn in the earth upon the top of the mount- ains" (Psalm lxxii. 4, 13, 1G). "And the work of righteousness shall be peace ; and the effect of righteousness, quietness and assurance for ever " (Isaiah xxxii. 17). " Surely I will no more give thy corn to be meat for thine enemies, and the sons of the stranger shall not drink thy wine, for the which thou hast laboured ; but they that have gath- ered it shall eat it, and praise the Lord ; and they that have brought it together shall drink it in the courts of My holiness " (Isaiah lxii. 8, 9). In the New Jerusalem " there shall be no more sorrow nor cry- ing." "They shall not build, and another inhabit; they shall not plant, and another eat ; for as the days of a tree are the days of My people, and Mine elect shall long enjoy the work of their hands " (Isaiah lxv. 21, 22). The prophet thus raises his voice in favour of the poor, in the name of justice, not of charity and mercy. " The Lord will enter into judgment with the ancients of His people and the princes thereof : for ye have eaten up the vineyard ; the spoil of the poor is in your houses. What mean ye that ye beat My people to pieces, and grind the faces of the poor ? saith the Lord God of hosts " (Isaiah iii. 14, 15). " Woe unto them that join house to house, that lay field to field till there be no place, that they may be placed alone in the midst of the earth " (Isaiah v. 8). In the future society property will be en- sured to all, and every one will " sit under his vine and under his fig- tree" (Micah iv. 4). The ideal of the prophets comprehends, then, in the first place, the triumph of justice, which will bring liberty to the oppressed, consola- tion to the outcast, and the produce of their labours to the workers ; and secondly, and chiefly, it will bring the glorification and domina- tion of the elect people — Israel. The ideal of the Gospel makes less of this second consideration of national grandeur and pre-eminence, and places in the foreground the radical transformation of the social order. The Gospel is the " good tidings of great joy," the ~E>vayyi\iov, carried to the poor, the approach of the Kingdom of God — that is to say, of the reign of jus- tice. " The last shall be first ; " therefore the pretended " natural order " will be reversed ! Who will possess the earth ? Not the mightiest, as in the animal creation, and as Darwinian laws decree ; not the rich, " for it is easier for a camel to go through a needle's eye than for a rich man to enter the Kingdom of God." Lazarus is received into Abraham's bosom, while Dives is cast into the place of torment, " where there is weeping and gnashing of teeth." The first of biological precepts, 186 THE POPULAR SCIENCE MONTHLY. the one respecting the survival of the fittest, as it immolates others for personal benefit, is essentially selfish, which is a vice incessantly- reprobated in the New Testament. "Look not every man on his own things, but every man also on the things of others " (Philip- pians ii. 4). The chief of all Christian virtues is charity ; it is the very essence of the Gospel. " Seek ye first the Kingdom of God and His righteousness, and all these things shall be added unto you " (St. Matthew vi. 33). How very true is the economic doctrine that, with equitable laws, each should enjoy the integral produce of his labour, and that, were this the case, personal activity would attain its highest degree. Noth- ing is more adverse to the prosperity of a nation than unjust laws ; and this is precisely what the prophets and Christ teach us. If Darwinian laws were applied to human society, the utility of history, considered as a moral lesson for both kings and people, would be destroyed. The history of man might then be looked upon as a mere zoological strife between nations, and a simple lengthening out of natural history. What moral instruction can possibly be drawn from the study of the animal world, where the strong devour or destroy the weak ? No spectacle could be more odious or more demoralizing ! The incomparable sublimity of the Gospel, which is, alas ! only too often misinterpreted, consists in an ardent longing for perfection, in that aspiration for an ideal of justice which urged Jesus and His earliest disciples to condemn the world as it then was. Thence sprang the hatred of evil in its many various forms, the desire for better things, for reforms and progress ! Why do Mahometans stand still in the march of civilization, while Christian countries advance ever more and more rapidly ? Because the first are resigned to evil, whereas the second combat and endeavour to extirpate it. The stoicism — the elevated character of which can hardly be sufficiently admired — the austerity, and purity of such ancients as Marcus Aurelius, neverthe- less, bowed before absolute facts, looking upon them as the inevitable results of the actual and natural order of things. Like modern evolu- tionists, they glorified the laws of nature, considering them perfect. Their optimism led them so far as to adore the cosmos as a divinity. " All that thou wilt, O Cosmos," says Marcus Aurelius, " is my will ; nothing is too early or too late for me, if it be at the hour thou decid- est upon. My fruit is such as thy seasons bring, O Nature ! From thee comes all. Thou art all. All go towards thee. If the gods be essentially good and just, they must have permitted nothing, in the arrangement of the world, contrary to right and justice." What a contrast between this serene satisfaction and the complaints of Job, of the prophets, and of Christ Himself ! The true Christian, in direct opposition to stoics and to Mr. Herbert Spencer, holds that the world is completely infected with evil ; he avoids it carefully, and lives in the hope of a general cataclysm, which will reduce our globe to ashes, THE STATE VERSUS THE MAN. 187 and make place for a new and purified heaven and earth ! The belief of stoics and of evolutionary sociologists logically advocates inaction, for it respects the present order of things as attributable to natural laws. The Christian's belief leads him to ardently desire reform and progress, but also, when he is deceived and reduced to despair, it occa- sionally culminates in revolutionary violence and in Nihilism. Not only Jesus, but all great religious reformers, such as Buddha, Mahomet, Luther, and the great philosophers, especially Socrates and Plato, and the great lawgivers, from Solon and Lycurgus to the legis- lators of the French Revolution — all the elect of humanity, in fact — are struck with the evils under which our race is forced to suffer, and have imagined and revealed an ideal social order more in conformity with the ideal of justice ; and in their writings they place this Utopia in contrast with the existing order. The more Christianity becomes despoiled of dogmas, and the more the ideas of moral and social reform, contained in Christ's teachings, are brought forward as the chief aim, the more Mr. Herbert Spencer's principles will be shunned and avoided. In the splendid development of Roman law, which lasted fifteen hundred years, a similar evolution took place. In the beginning, in the laws of the twelve tables, many traces of the hard law in favour of the mighty may be found. This is symbolized by the lance (quir), which gave its name to the quiritarian right. The father was allowed to sell or destroy his children, as they were his possession. He had absolute power over his slaves, who were his " things." The creditor might throw his debtor in prison, or even cause him to be cut in pieces — in partes secanto. The wife was entirely in her husband's power — in manu. Little by little, as centuries rolled on, eminent lawgivers succeeded each other, and gradual changes were made, so that, finally, just and humanitarian principles penetrated the entire Roman code, and the Darwinian law, which glorifies might, gave place to the Christian law, which extols justice. This movement will most assuredly continue, in spite of all the abuse it may receive from Mr. Herbert Spencer, and from others who think as he does. It is a result of the advance of civilization from the commencement of Christianity, and even from the time of the prophets of Israel. It will manifest itself, not as it did in the middle ages, by works of mercy, but, under the control of economic science, by the intervention of the State in favour of the disinherited, and by measures such as Mr. Shaw Lefevre approves of, so that each and all should be placed in a position to be able to command reward in proportion to the amount of useful labour accomplished. Darwinian laws, generally admitted in the domain of natural history and in the animal kingdom, will never be applied to human societies, until the sentiments of charity and justice, which Christianity engraves on our hearts, are completely eradicated. — Contemporary Review. 188 THE POPULAR SCIENCE MONTHLY. A REJOINDER TO M. DE LAYELEYE. By IIEEBERT SPENCEK. THE Editor of the Contemporary Review having kindly allowed me to see a proof of the foregoing article by M. de Laveleye, and having assented to my request that I might be allowed to append a few explanations and comments, in place of a more formal reply in a future number of the Review, I have, in the following pages, set down as much as seems needful to prevent the grave misunderstandings likely to be produced by M. de Laveleye's criticisms, if they are per- mitted to pass unnoticed. On the first page of his essay, M. de Laveleye, referring to the effort to establish " greater equality among men " by " appropriating State, or communal, revenues " for that end, writes — "Mr. Spencer considers that this effort for the improvement of the condition of the working-classes, which is being everywhere made with greater or less energy, is a violation of natural laws, which will not fail to bring its own pun- ishment on nations, thus misguided by a blind philanthropy " (p. 485). As this sentence stands, and especially as joined with all which fol- lows, it is calculated to produce the impression that I am opposed to measures " for the improvement of the condition of the working- classes." This is quite untrue, as numerous passages frcam my books would show. Two questions are involved — What are the measures ? and — What is the agency for carrying them out ? In the first place, there are various measures conducive to " improvement of the condi- tion of the working-classes " which I have always contended, and still contend, devolve on public agencies, general and local — above all, an efficient administration of justice, by which they benefit both directly and indirectly — an administration such as not simply represses violence and fraud, but promptly brings down a penalty on every one who trespasses against his neighbour, even by a nuisance. While contend- ing for the diminution of State-action of the positively-regulative kind, I have contended for the increase of State-action of the negatively- regulative kind — that kind which restrains the activities of citizens within the limits imposed by the existence of other citizens who have like claims to carry on their activities. I have shown that " malad- ministration of justice raises, very considerably, the cost of living for all ; " * and is, therefore, felt especially by the working-classes, whose state is most closely dependent on the cost of living. As one of the evils of over-legislation, I have, from the beginning, urged that, while multitudinous other questions absorb public attention, the justice- question gets scarcely any attention ; and social life is everywhere * " Study of Sociology," p. 415, postscript in library edition. A REJOINDER TO M. BE LAVELEYE. 189 vitiated by the consequent inequities.* While defending laissez-faire in its original and proper sense, I have pointed out that the policy of universal meddling has for its concomitant that vicious laissez-faire which leaves dishonesty to flourish at the expense of honesty.f In the second place, there are numerous other measures conducive to "the improvement of the condition of the working-classes " which I desire quite as much as M. de Laveleye to see undertaken ; and simply differ from him concerning the agency by which they shall be undertaken. Without wishing to restrain philanthropic action, but quite contrari- wise, I have in various places argued that philanthropy will better achieve its ends by non-governmental means than by governmental means.J M. de Laveleye is much more familiar than I am with the facts showing that, in societies at large, the organized arrangements which carry on production and distribution have been evolved not only without State-help, but very generally in spite of State-hindrance ; and hence I am surprised that he apparently gives no credence to the doctrine that, by private persons acting either individually or in com- bination, there may be better achieved multitudinous ends which it is the fashion to invoke State-agency for. Speaking of the domain of individual liberty, M. de Laveleye says — "To be brief, I agree with Mr. Herbert Spencer that, contrary to Rousseau's doctrine, State power ought to be limited, and that a domain should be reserved to individual liberty which should be always respected ; but the limits of this domain should be fixed, not by tbe people, but by reason and science, keeping in view what is best for the public welfare " (p. 488). I am a good deal perplexed at finding the last clause of this sentence apparently addressed to me as though in opposition. " Social Statics " is a work mainly occupied with the endeavour to establish these limits by " reason and science." In the " Data of Ethics," I have sought, in a chapter entitled the " Sociological View," to show how certain lim- its to individual liberty are deducible from the laws of life as carried on under social conditions. And in " The Man versus The State," which M. de Laveleye is more particularly dealing with, one part of the last chapter is devoted to showing, deductively, the derivation of what are called " natural rights " from the vital needs, which each man has to satisfy by activities pursued in presence of other men who have to satisfy like needs ; while another part of the chapter is de- voted to showing, inductively, how recognition of natural rights began, in the earliest social groups, to be initiated by those retaliations which trespasses called forth — retaliations ever tending to produce respect for the proper limits of action. If M. de Laveleye does not consider * See " Social Statics : ' The Duty of the State.' " Also " Essays," vol. ii. pp. 94-8 ; vol. iii. p. 167. •j- "Study of Sociology," pp. 351-3, cheap edition. % " Social Statics : ' Poor Laws.' " i9o THE POPULAR SCIENCE MONTHLY. this to be an establishment of limits " by reason and science," what are the kinds of " reason and science " by which he expects to estab- lish them ? On another page M. de Laveleye says — " I am of opinion that the State should make use of its legitimate powers of action for the establishment of greater equality among men, in proportion to their personal merits " (p. 489). Merely observing that the expression " its legitimate powers of action " seems to imply a begging of the question, since the chief point in dispute is — What are " its legitimate powers of action ; " I go on to express my surprise at such a sentence coming from a distinguished political economist. M. de Laveleye refers to the "old-fashioned political economy," implying that he is one of those younger econo- mists who dissent from its doctrine ; but I was quite unprepared to find that his dissent went so far as tacitly to deny that in the average of cases a proportioning of rewards to personal merits naturally takes place under the free play of supply and demand. Still less, after all the exposures made of the miseries inflicted on men throughout the past by the blundering attempts of the State to adjust prices and wages, did I expect to see in a political economist such a revived con- fidence in the State as would commission it to adjust men's rewards " in proportion to their personal merit." I hear that there are some who contend that payment should be proportionate to the disagree- ableness of the work done : the implication, I suppose, being that the knacker and the nightman should reeeive two or three guineas a day, while a physician's fee should be half-a-crown. But, with such a proportioning, I suspect that, as there would be no returns adequate to repay the cost and time and labor of preparation for the practice of medicine, physicians would quickly disappear ; as would, indeed, all those required for the higher social functions. I do not suppose that M. de Laveleye contemplates a proportioning just of this kind. But if in face of all experience, past and present, he trusts officialism to judge of "personal merits," he is sanguine to a degree which sur- prises me. One of the questions which M. de Laveleye asks is — "If the intervention of public power for the improvement of the condition of the working-classes be a contradiction of history, and a return to ancient militant society, how is it that the country in which the new industrial organi- zation is the most developed — that is to say, England — is also the country where State intervention is the most rapidly increasing, and where opinion is at the same time pressing for these powers of interference to be still further extended ? " (p. 491). Several questions are here raised besides the chief one. I have already pointed out that my objection is not to " intervention of public power for the improvement of the condition of the working-classes," A REJOINDER TO M. BE LAVELEYE. 191 but to interventions of certain kinds. The abolition of laws forbid- ding trade-combinations, and of laws forbidding the travelling of artisans, were surely measures which improved " the condition of the working-classes ; " and these were measures which I should have been eager to join in obtaining. Similarly, at the present time I am desirous of seeing provided the easiest and most efficient remedies for sailors fraudulently betrayed into unseaworthy ships ; and I heartily sympathize with those who denounce the continual encroachments of landowners — enclosures of commons and the turf-covered borders of lanes, &c. These, and kindred injustices to the working - classes, stretching far back, I am no less desirous to see remedied than is M. de Laveleye ; provided always that due care is taken that other injustices are not committed in remedying them. Evidently, then, this expression of M. de Laveleye raises a false issue. Again, he says that I call this public intervention on behalf of the working-classes " a return to ancient militant society." This is quite a mistake. In ancient militant society the condition of the working-classes was very little cared for, and, indeed, scarcely thought of. My assertion was that the coercive system employed, was like the coercive system em- ployed in a militant society : the ends to which the systems are directed, being quite different. But turning to the chief point in his question, I meet it by counter-questions — Why is it that the " new industrial organization" is best developed in England? and — Under what conditions was it developed ? I need hardly point out to M. de Laveleye that the period during which industrial organization in Eng- land developed more rapidly and extensively than elsewhere, was a period during which the form of government was less coercive than elsewhere, and the individual less interfered with than elsewhere. And if now, led by the admirers of Continental bureaucracies, eager philanthropists are more rapidly extending State-administrations here than they are being extended abroad, it is obviously because there is great scope for the further extension of them here, while abroad there is little scope for the further extension of them. In justification of coercive methods for "improving the condition of the working-classes," M. de Laveleye says : " One fact is sufficient to show the great progress due to this State legisla- tion : in an ever-increasing population, crime is rapidly and greatly diminish- ing" (p. 496). Now, without dwelling on the fact, shown in Mr. Pike's " History of Crime in England," that " violence and lawlessness " had increased during the war period which ended at Waterloo ; and without dwell- ing on the fact that, after the recovery from prostration produced by war, there was a diminution of crime along with that great diminution of coercive legislation which characterized the long period of peace ; I go on to remark that a primary condition to the correct drawing of 192 THE POPULAR SCIENCE MONTHLY. inferences is — other tilings equal. Does M. de Laveleye really think, when comparing the state of the last generation with that of the present, that other things are so equal that to the growth of State- administrations can be ascribed the decrease of crime ? He ignores those two factors, far more important than all others, which have pro- duced a social revolution — railways and free-trade : the last resulting from the abolition of governmental restraints after a long struggle, and the first effected by private enterj^rise carried out in spite of strenuous opposition for some time made in the Legislature. Beyond all question, the prosperity due to these factors has greatly ameliorated the condition of the working-classes, and by so doing has diminished crime ; for undoubtedly, diminishing the difficulties of getting food, diminishes one of the temptations to crime. If M. de Laveleye refers to a more recent diminution, then, unless he denies the alleged relation between drunkenness and crime, he must admit that the temperance agitation, with its pledges, its " Bands of Hope," and its " Blue Rib- bon League," has had a good deal to do with it. Before passing to the chief question let me correct M. de Laveleye on some minor points. He says — "I think that the great fundamental error of Mr. Herbert Spencer's system, which is so generally accepted at the present day, consists iu the helief that if State power were hut sufficiently reduced," &c. Now I set against this a sentence not long since published by Mr. Frederic Harrison : "Mr. Spencer has himself just published .... 'The Man versus The State,' to which he hardly expects to make a convert except here and there, and about which an unfriendly critic might say that it might be entitled 'Mr. Spencer against all England.' " {Nineteenth Century, vol. xvi. p. 366.) The fear lest my arguments should prevail, which I presume prompted M. de Laveleye's article, is evidently ill-founded. I wish I saw reason to believe that his estimate is nearer to the truth than the opposite one. On p. 490, M. de Laveleye writes — " The law that Mr. Herbert Spencer desires society to adopt is simply Dar- win's law — ' the survival of the fittest.' " ■$ Perhaps I may be excused for wishing here to prevent further con- firmation of a current error. In his article, M. de Laveleye has quoted from " Social Statics " passages showing insistance on the benefits re- sulting from survival of the fittest among mankind, as well as among animals ; though he ignores the fact that the work as a whole is an elaborate statement of the conditions under which, and limits within which, the natural process of elimination of the unfit should be allowed to operate. Here my immediate purpose is to correct the impression which his statement, as above worded, produces, by naming the dates : A REJOINDER TO M. DE LAVELEYE. 193 "Social Statics" was published in 1851 ; Mr. Darwin's "Origin of Spe- cies" in 1859. And now I pass to the main issue. In pursuance of his statement that I wish society to adopt the survival of the fittest as its guiding principle, M. de Laveleye goes on to describe what would be its action as applied to mankind. Here are his words : " This is the ideal order of things which, we are told, ought to prevail in human societies, but everything in our present organization (which economists, and even Mr. Spencer himself, admit, however, to be natural) is wholly opposed to any such conditions. An old and sickly lion captured a gazelle ; his younger and stronger brother arrives, snatches away his prize, and lives to perpetuate the species; the old one dies in the struggle, or is starved to death. Such is the beneficent law of the 'survival of the fittest.' It was thus among barbarian tribes. But could such a law exist in our present social order? Certainly not! The rich man, feebly constituted and sickly, protected by the law, enjoys his wealth, marries and has offspring, and if an Apollo of herculean strength at- tempted to take from him his possessions, or his wife, he would be thrown into prison, and were he to attempt to practise the Darwinian law of selection, be would certainly run a fair risk of the gallows" (p. 492). Now though, on the next page, M. de Laveleye recognizes the fact that the survival of the fittest, as I construe it in its social applica- tions, is the survival of the industrially superior and those who are fittest for the requirements of social life, yet, in the paragraph I have quoted, he implies that the view I hold would countenance violent methods of replacing the inferior by the superior. Unless he desires to suggest that I wish to see the principle operate among men as it operates among brutes, why did he write this paragraph ? In the work before him, without referring to other works, he has abundant proof that, above all things, aggression of every kind is hateful to me ; and he scarcely needs telling that from my earliest book, written more than a third of a century ago, down to the present time, I have urged the change of all laws which either inflict injustice or fail to remedy injustice, whether committed by one individual against another, or by class against class, or by people against people. Why, then, did M. de Laveleye make it seem that I would, if I could, establish a reign of injustice under its most brutal form ? If there needs proof that in my view the struggle for existence as carried on in society, and the greater multiplication of those best fitted for the struggle, must be subject to rigorous limitations, I may quote as sufficient proof a pas- sage from the " Data of Ethics : " premising that the word co-opera- tion used in it, must be understood in its widest sense, as comprehend- ing all those combined activities by which citizens carry on social life: " The leading traits of a code under which complete living through volun- tary co-operation [here antithetically opposed to compulsory co-operation, char- acterizing the militant type of society] is secured, may be simply stated. The fundamental requirement is that the life-sustaining actions of each shall sever- vol. xxvii. — 13 i94 THE POPULAR SCIENCE MONTHLY. ally bring him the amounts and kinds of advantage naturally achieved by them ; and this implies, firstly, that he shall suffer no direct aggressions on his person or property, and, secondly, that he shall suffer no indirect aggressions by breach of contract. Observance of these negative conditions to voluntary co-operation having facilitated life to the greatest extent by exchange of services under agree- ment, life is to be further facilitated by exchange of services beyond agreement ; the highest life being reached only when, besides helping to complete one another's lives by specified reciprocities of aid, men otherwise help to complete one another's lives " (p. 149). This passage, indeed, raises in a convenient form the essential ques- tion. It will be observed that in it are specified two sets of conditions, by conforming to which men living together may achieve the greatest happiness. The first set of conditions is that which we comprehend under the general name justice / the second set of conditions is that which we comprehend under the general name generosity. The posi- tion of M. de Laveleye, and of the multitudes who think with him, is that the community, through its government, may rightly undertake both to administer justice and to practise generosity. On the other hand, I, and the few who think with me, contend that justice alone is to be administered by the community in its corporate capacity ; and that the practice of generosity is to be left to private individuals, and voluntarily-formed combinations of individuals. Insuring each citi- zen's safety in person and property, as well as insuring him such re- turns for his services as his fellow-citizens agree to give, is a public affair ; while affording him help, and giving him benefits beyond those he has earned, is a private affair. The reason for maintaining this dis- tinction is that the last duty can not be undertaken by the State with- out breach of the first. The vital requirement to social life must be broken that a non-vital requirement may be fulfilled. Under a reign of absolute justice unqualified by generosity, a social life may be car- ried on, though not the highest social life ; but a reign of generosity without any justice — a system under which those who work are not paid, so that those who have been idle or drunken may be saved from misery — is fatal ; and any approach to it is injurious. That only can be a wholesome state in which conduct brings its natural results, good or evil, as the case may be ; and it is the business of Government, act- ing on behalf of all, to see that each citizen shall not be defrauded of the good results, and that he shall not shoulder off the evil results on to others. If others, in their private capacities, are prompted by affec- tion or pity to mitigate the evil results, by all means let them do so : no power can equitably prevent them from making efforts, or giving money, to diminish the sufferings of the unfortunate and the inferior ; at the same time that no power can equitably coerce them into doing this. If M. de Laveleye holds, as he appears to do, that enforcing the normal relations between conduct and consequences, right as it may WHALES, PAST AND PRESENT. 195 be in the abstract, is impracticable under existing social conditions, which are in many cases such that men get what they have neither earned nor otherwise equitably received, and in many cases such that they are prevented from earning anything ; then my reply is, by all means, where this condition of things is due to unjust arrangements, let us rectify these arrangements as fast as we can. But let us not adopt the disastrous policy of establishing new injustices for the pur- pose of mitigating the mischiefs produced by old injustices. — Contem- porary JReview. ~+*+~ WHALES, PAST AND PKESENT.* By Pbofessob W. H. FLOWER, F. R. S. FEW natural groups present so many remarkable illustrations of several of the most important general laws which appear to have determined the structure of animal bodies as that of the whales. We find the effects of the two opposing forces — that of heredity or con- formation to ancestral characters, and that of adaptation to changed environment, whether brought about by the method of natural selec- tion or otherwise — distinctly written in almost every part of their structure. Scarcely anywhere in the animal kingdom do we see so many cases of the persistence of rudimentary and apparently useless organs, those marvelous and suggestive phenomena which at one time seemed hopeless enigmas, causing despair to those who tried to unravel their meaning, but now eagerly welcomed as beacons of true light, casting illuminating beams upon the dark paths through which the organism has traveled on its way to reach the goal of its present con- dition of existence. It is chiefly to these rudimentary organs of the Cetacea and to what we may learn from them that I propose to call your attention. In each case the question may well be asked, Are they survivals, rem- nants of a past condition, become useless owing to change of circum- stances and environment ; or are they incipient structures, beginnings of what may in future become functional and important parts of the economy ? The term " whale " is commonly but vaguely applied to all the larger and middle-sized Cetacea, and, though such smaller species as the dol- phins and porpoises are not usually spoken of as whales, they may to all intents and purposes of zoological science be included in the term. Taken all together the Cetacea constitute a distinct and natural order of mammals, characterized by their aquatic mode of life and external fish- like form. The body is fusiform, passing anteriorly into the head with- out any distinct constriction or neck, and posteriorly tapering off grad- * Abridged from a lecture delivered at the Royal Institution, London, May 25, 1883. 196 THE POPULAR SCIENCE MONTHLY. ually toward the extremity of the tail, which is provided with a pair of lateral pointed expansions of skin supported by dense fibrous tissue, called "flukes," forming together a horizontally placed, triangular pro- pelling organ. The fore-limbs are reduced to the condition of flattened ovoid paddles, incased in a continuous integument, showing no external sign of division into arm, fore-arm, and hand, or of separate digits, and without any trace of nails. There are no vestiges of hind-limbs visible externally. The general surface of the body is smooth and glistening, and devoid of hair. In nearly all species a compressed median dorsal fin is present. The nostrils open separately or by a single crescentic valvular aperture, not at the extremity of the snout, but near the vertex. Animals of the order Cetacea abound in all known seas, and some species are inhabitants of the larger rivers of South America and Asia. Their organization necessi- H^ tates their life being passed entirely in the water, as on g the land they are absolutely jg helpless ; but they have to rise very frequently to the surface for the purpose of respiration. They are all pre- daceous, subsisting on living animal food of some kind. One genus alone ( Orca) eats other warm-blooded animals, as seals and even members of its own order, both large and small. Some feed on fish, others on small floating Crustacea, pteropods, and medusa?, while the staple food of many is constituted of the various species of Cephalopods. With some exceptions the Cetacea generally are timid, inoffensive animals, active in their movements, sociable and gregarious in their habits. Among the existing members of the order there are two very dis- tinct types — the toothed whales, or Odontoceti, and the baleen (whale- bone) whales, or Mystacoceti, which present throughout their organi- zation most markedly distinct structural characters, and have in the existing state of nature no transitional forms. The problem of the origin of the Cetacea and their relations to other forms of life is at present involved in the greatest obscurity. They present no more signs of affinity with any of the lower classes of vertebrated animals than do many of the members of their own class. Indeed, in all that essentially distinguishes a mammal from one of the oviparous vertebrates, they are as truly mammalian as any, even the highest, members of the class. Any supposed signs of inferiority are simply modifications in adaptation to their peculiar mode of life. In the present state of our knowledge, the Cetacea Fig. 1.— Common Dolphin. WHALES, PAST AND PRESENT. 197 are absolutely isolated, and little satisfactory reason has ever been given for deriving them from any one of the existing divisions of the class more than from any other. The question has indeed often been mooted whether they have been derived from land mam- mals at all, or whether they may not be the survivors of a primitive aquatic form which was the ancestor not only of the whales, but of all the other members of the class. The materials for — I will not say solving — but for throwing some light upon this problem, must be sought for in two regions — in the structure of the existing members of the order, and in its past history, as revealed by the _, — Vv-~-- -7^ ._.__^ ^ > discovery of fossil remains. ^^^Ws -- ~ — - « - — •— — In the present state of science ^^(Kz: --------- fi^. ~ it is chiefly on the former ~^^«s^^^^^^^^^s^ that we have to rely. ofc& One of the most obvious ~~-^.~- _' -*^^P^: external characteristics by -7*%- which the mammalia arc dis- \ :: ^0^^) ^ <^5Smi tino-uished from other classes - ., *a^%-=-T*w ==-: of vertebrates is the more or Hit : JW less complete clothing of the ^^^ff^^^^^^^^g" surface by hair. The Cetacea , i , . Fig. 2.— Common Porpoise. alone appear to be exceptions to this generalization. Their smooth, glistening exterior is, in the greater number of species, at all events in adult life, absolutely bare, though the want of a hairy covering is compensated for functionally by peculiar modifications of the structure of the skin itself, the epider- mis being greatly thickened, and a remarkable layer of dense fat closely incorporated with the tissue of the derm or true skin ; modifications admirably adapted for retaining the warmth of the body, without any roughness of surface which might occasion friction and so interfere with perfect facility of gliding through the water. Close examination, however, shows that the mammalian character of hairiness is not en- tirely wanting in the Cetacea, although it is reduced to a most rudi- mentary and apparently functionless condition. In the organs of the senses the Cetacea exhibit some remarkable adaptive modifications of structures essentially formed on the mamma- lian type, and not on that characteristic of the truly aquatic verte- brates, the fishes. The modifications of the organs of sight do not so much affect the eyeball as the accessory apparatus. To an animal whose surface is always bathed with fluid, the complex arrangement which mammals generally possess for keeping the surface of the transparent cornea moist and protected, the movable lids, the nictitating membrane, the lachrymal gland, and the arrangements for collecting and removing the superfluous tears when they have served their function can not be 198 THE POPULAR SCIENCE MONTHLY. needed, and hence we find these parts in a most rudimentary condition or altogether absent. In the same way the organ of hearing in its essential structure is entirely mammalian, having not only the sacculi and semicircular canals common to all but the lowest vertebrates, but the cochlea, and tympanic cavity with its ossicles and membrane, all, however, buried deep in the solid substance of the head ; while the parts specially belonging to terrestrial mammals, those which collect the vibrations of the sound traveling through air, the pinna and the tube which conveys it to the sentient structures within, are entirely or practically wanting. Of the pinna or external ear there is no trace. The organ of smell, when it exists, offers still more remarkable evidence of the origin of the Cetacea. In fishes this organ is specially adapted for the perception of odorous substances permeating the water ; the terminations of the olfactory nerves are spread over a cavity near the front pai't of the nose, to which the fluid in which the animals swim has free access although it is quite unconnected with the respiratory passages. Mammals, on the other hand, smell substances with which the atmosphere they breathe is impregnated ; their olfac- tory nerve is distributed over the more or less complex foldings of the lining of a cavity placed in the head, in immediate relation to the pas- sages through which air is continually driven to and fro on its way to the lungs in respiration, and therefore in a most favorable position for receiving impressions from substances floating in that air. The whale- bone whales have an organ of smell exactly on the mammalian type, but in a rudimentary condition. In the more completely modified Odontocetes the olfactory apparatus, as well as that part of the brain specially related to the function of smell, is entirely wanting, but in both groups there is not the slightest trace of the specially aquatic olfactory organ of fishes. Its complete absence and the vestiges of the aerial organ of land mammals found in the Mystacocetes are the clearest possible indications of the origin of the Cetaceae from air- breathing and air-smelling terrestrial mammalia. With their adapta- tion to an aquatic mode of existence, organs fitted only for smelling in air became useless, and so have dwindled or completely disappeared. Time and circumstances have not permitted the acquisition of any- thing analogous to the special aquatic smelling apparatus of fishes, the result being that whales are practically deprived of whatever advantage this sense may be to other animals. All the Cetacea present some traces of teeth, which in structure and mode of development resemble those of mammals, and not those of the lower vertebrated classes, but they are always found in a more or less impei'fect state. The meaning and utility of some of the strange modifications in the dentition of whales it is impossible, in the imperfect state of our knowledge of the habits of the Cetacea, to explain, but the fact that in almost every case a more full number of rudimentary teeth is pres- WHALES, PAST AND PRESENT. 199 ent in early stages of existence, which either disappear, or remain as concealed and functionless organs, points to the present condition in the aberrant and specialized forms as being one derived from the more generalized type, in which the teeth were numerous and equal. Fig. 3.— Toothed Whale, or Spermaceti Whale. The Mystacocetes, or whalebone whales, are distinguished by en- tire absence of teeth, at all events after birth. But it is a remarkable fact, first demonstrated by Geoffroy Saint-Hilaire, and since amply confirmed by Cuvier, Eschricht, Julin, and others, that in the fetal state they have numerous minute calcified teeth lying in the dental groove of both upper and lower jaws. These attain their fullest development about the middle of fetal life, after which period they are absorbed, no trace of them remaining at the time of birth. Their structure and mode of development have been shown to be exactly those characteristic of ordinary mammalian teeth. It is not until after the disappearance of these teeth that the baleen, or whalebone, makes its appearance. This remarkable structure, though only a modification of a part existing in all mammals, is, in its specially developed con- dition as baleen, peculiar to one group of whales. Baleen consists of a series of flattened, horny plates, several hun- dred in number, on each side of the palate, separated by a bare interval along the middle line. They are placed transversely to the long axis of the palate, with very short spaces between them. Each plate or blade is somewhat triangular in form, with the base attached to the palate, and the apex hanging downward. The outer edge of the blade is hard and smooth, but the inner edge and apex fray out into long, 200 THE POPULAR SCIENCE MONTHLY. bristly fibers, so that the roof of the whale's mouth looks as if covered with hair, as described by Aristotle. The blades are longer near the middle of the series, and gradually diminish near the front and back of the mouth. The horny plates grow from a dense, fibrous, and highly vascular matrix, which covers the palatal surface of the maxillae, and which sends out lamellar processes, one of which penetrates the base of each blade. Moreover, the free edge of these processes is covered with very long, vascular, thread-like papillae, one of which forms the central axis of each of the hair-like epidermic fibers of which the blade is mainly composed. The blades are supported and bound together, for a certain distance from their base, by a mass of less hardened epithelium, secreted by the surface of the palatal membrane or matrix of the whale- bone in the intervals of the lamellar processes. This is the " interme- diate substance " of Hunter, the " gum " of the whalers. The function of the whalebone is to strain the water from the small marine mollusks, crus- taceans, or fish upon which the whales subsist. In feeding they fill the immense mouth with water containing shoals of these small creatures, and then, on their closing the jaws and raising Fig. 4.— Whalebone Whale, or Greenland Whale. the tongue, so as to diminish the cavity of the mouth, the water streams out through the narrow intervals between the hairy fringe of the whale- bone blades, and escapes through the lips, leaving the living prey to be swallowed. Almost all the other structures to which I am specially directing your attention are in a more or less rudimentary state in the Cetacea ; the baleen, on the other hand, is an example of an ex- actly contrary condition, but an equally instructive one, as illustrating the mode in which Nature works in producing the infinite variety we WHALES, PAST AND PRESENT. 201 see in animal structures. Although appearing at first sight an entirely- distinct and special formation, it evidently consists of nothing more than the highly modified papillae of the lining membrane of the mouth, with an excessive and cornified epithelial development. The bony palate of all mammals is covered with a closely-adhering layer of fibro-vascular tissue, the surface of which is protected by a coating of non-vascular epithelium, the former exactly corresponding to the derm or true skin, and the latter to the epiderm of the external surface of the body. Sometimes this membrane is perfectly smooth, but it is more often raised into ridges, which run in a direction trans- verse to the axis of the head, and are curved with the concavity back- ward ; the- ridges, moreover, do not extend across the middle line, being interrupted by a median depression or raphe. Indications of these ridges are clearly seen in the human palate, but they attain their great- est development in the Ungulata. Though the early stages by which whalebone has been modified from more simple palate structures are lost to our sight, the conditions in which it now exists in different species of whales show very marked varieties of progress, from a simple, comparatively rudimental and im- perfect condition, to what is perhaps the most wonderful example of mechanical adaptation to purpose known in any organic structure. In the rorquals or fin-whales (genus Balcenopterd), found in almost ail seas, the largest blades in an animal of seventy feet in length do not exceed two feet in length, including their hairy terminations ; they are in most species of a pale horn color, and their structure is coarse and inelastic, separating into thick, stiff fibers, so that they are of no value for the ordinary purposes to which whalebone is applied in the arts. These animals feed on fish of considerable size, from herrings up to cod, and for foraging among shoals of these creatures the construction of their mouth and the structure of their baleen are evidently sufficient. This is the type of the earliest known extinct forms of whales, and it has continued to exist, with several slight modifications, to this day, because it has fulfilled one purpose in the economy of Nature. Other purposes for which it was not sufficient have been supplied by gradual changes taking place, some of the stages of which are seen in the inter- mediate conditions still exhibited in the Megaptera and the Atlantic and southern right whales. In the Greenland right whale of the circumpolar seas, the Bow- head of the American whalers {Balcena mysticetus), all the peculiari- ties which distinguish the head and mouth of the whales from other mammals have attained their greatest development. The head is of enormous size, exceeding one third of the whole length of the creat- ure. The cavity of the mouth is actually larger than that of the body, thorax, and abdomen together. The upper jaw is very narrow, but greatly arched from before backward, to increase the height of the cavity and allow for the great length of the baleen ; the enormous rami 202 THE POPULAR SCIENCE MONTHLY. of the mandibles are widely separated posteriorly, and have a still further outward sweep before they meet at the symphysis in front, giving the floor of the mouth the shape of an immense spoon. The baleen-blades attain the number of three hundred and fifty or more on each side, and those in the middle of the series have a length of ten or even twelve feet. They are black in color, fine and highly elastic in texture, and fray out at the inner edge and ends into long, delicate, soft, almost silky, but very tough hairs. Fig. 5.— Skull op Greenland Whale, showing Whalebone. How these immensely long blades, depending vertically from the palate, were packed into a mouth the height of which was scarcely more than half their length, was a mystery not solved until a few years ago. Captain David Gray, of Peterhead, at my request, first gave us a clear idea of the arrangement of the baleen in the Greenland whale, and showed that the purpose of its wonderful elasticity was not primarily at least the benefit of the corset and umbrella makers, but that it was essential for the correct performance of its functions. It may here be mentioned that the modification of the mouth-structure of the right whale is entirely in relation to its food. It is by this appa- ratus that it is enabled to avail itself of the minute but highly nutri- tious crustaceans and pteropods which swarm in immense shoals in the seas it frequents. The large mouth enables it to take in at one time a sufficient quantity of water filled with these small organisms, and the length and delicate structure of the baleen make it an efficient strainer or hair sieve by which the water can be drained off. If the baleen were, as in the rorquals, short and rigid, and only of the length of the aperture between the upper and lower jaws when the mouth was shut, when the jaws were separated a space would be left beneath it through which the water and the minute particles of food would escape together. But, instead of this, the long, slender, brush-like ends of the whalebone-blades, when the mouth is closed, fold back, the front ones passing below the hinder ones in a channel lying between the WHALES, PAST AND PRESENT. 203 tongue and the bone of the lower jaw. When the mouth is opened their elasticity causes them to straighten out like a bow that is unbent, so that, at whatever distance the jaws are separated, the strainer remains in perfect action, filling the whole of the interval. The mechanical perfection of the arrangement is completed by the great development of the lower lip, which rises stiffly above the jawbone, and prevents the long, slender, flexible ends of the baleen being carried outward by the rush of water from the mouth. Pig. 6.— Korqual. Few points of the structure of whales offer so great a departure from the ordinary mammalian type as the limbs. The fore-limbs are reduced to the condition of simple paddles or oars, variously shaped, but always flattened and more or less oval in outline. They are freely movable at the shoulder-joint, where the humerus or upper-arm bone articulates with the shoulder-blade in the usual manner, but beyond this point, except a slight flexibility and elasticity, there is no motion between the different segments. The bones are all there, correspond- ing in number and general relations with those of the human or any other mammalian arm, but they are flattened out, and their contiguous ends, instead of presenting hinge-like joints, come in contact by flat surfaces, iinited together by strong ligamentous bands, and all wrapped up in an undivided covering of skin, which allows externally of no sign of the separate and many-jointed fingers seen in the skeleton. The changes that have taken place in the hind-limbs are even more remarkable. In all known Cetacea (unless Platanista be really an exception) a pair of slender bones are found suspended a short dis- tance below the vertebral column, but not attached to it, about the part where the body and the tail join. In museum skeletons these bones are often not seen, as, unless special care has been taken in the preparation, they are apt to get lost. They are, however, of much importance and interest, as their relations to surrounding parts show that they are the rudimentary representatives of the pelvic or hip bones, which in other mammals play such an important part in con- 204 THE POPULAR SCIENCE MONTHLY. necting the hind-limbs with the rest of the skeleton. The pelvic arch is thus almost universally present, but of the limb proper there is, as far as is yet known, not a vestige in any of the large group of toothed whales, not even in the great Cachalot or sperm whale, although it should be mentioned that it has never been looked for in that animal with any sort of care. With regard to the whalebone whales, at least to some of the species, the case is different. In these animals there are found, attached to the outer and lower side of the pelvic bone, other elements, bony or only cartilaginous as the case may be, clearly representing rudiments of the first and in some cases the sec- ond segment of the limb, the thigh or femur, and the leg or tibia. "VYe have here a case in which it is not difficult to answer the ques- tion before alluded to, often asked with regard to rudimentary parts : Are they disappearing, or are they incipient organs ? We can have no hesitation in saying that they are the former. All we know of the origin of limbs shows that they commence as outgrowths upon the surface of the body, and that the first-formed portions are the most distal segments. The limb, as proved by its permanent state in the lowest vertebrates, and by its embryological condition in higher forms, is at first a mere projection or outward fold of the skin, which, in the course of development, as it becomes of use in moving or supporting the animal, acquires the internal framework which strengthens it and perfects its functions. It would be impossible, on any theory of causa- tion yet known, to conceive of a limb gradually developed from within outward. On the other hand, its disappearance would naturally take place in the opposite direction. We turn next to what the researches of paleontology teach of the past history of the order. Unfortunately, this does not at present amount to very much. We know nothing of their condition, if they existed, in the Mesozoic age. Even in the cretaceous seas not a frag- ment of any whale or whale-like animal has been found. The earliest Cetaceans, of whose organization we have any good evidence, are the Zeuglodons of the Eocene formations of North America. These were creatures whose structure, as far as we know it, was intermediate be- tween that of the existing sub-orders of whales. In fact, Zeuglodon is precisely what we might have expected a priori an ancestral form of whales to have been. From the middle Miocene period fossil Cetacea are abundant, and distinctly divided into the two groups now existing. The Mystacocetes, or whalebone whales, of the Miocene seas, were, as far as we know now, only Balmnopterw, some of which were more gen- eralized than any now existing. In the shape of the mandible also, Van Beneden discerns some approximation to the Odontocetes. Right whales (Halcena) have not been found earlier than the Pliocene period, and it is interesting to note that, instead of the individuals diminishing in balk as we approach the times we live in, as with many other groups of animals, the contrary has been the case, no known extinct species WHALES, PAST AND PRESENT. 205 Fig. 7.— Narwhal. of whales equaling in size those that are now to be met with in the ocean. The size of whales, as of all other things whose most striking attribute is magnitude, has been greatly exaggerated ; but, when re- duced to the limits of sober fact, the Greenland right whale of fifty feet long, the sperm whale of sixty, and the great northern rorqual (Balcenoptera Sibbaldii) of eighty, exceed all other or- ganic structures known, past or present. Instead of living in an age of degeneracy of physical growth, we are in an age of giants, but it may be at the end of that age. For countless ages impulses from within and the forces of circumstances from with- out have been gradually shaping the whales into their present wonderful form and gigantic size, but the very perfection of their structure and their mag- nitude combined, the rich supply of oil protecting their internal parts from cold, the beautiful apparatus of whalebone by which their nutri- tion is provided for, have been fatal gifts, which, under the sudden revolution produced on the surface of the globe by the development of the wants and arts of civilized man, can not but lead in a few years to their extinction. Let us return to the question with which we started, " What was the probable origin of whales ? " The evidence is absolutely conclu- sive that they were not originally aquatic in habit, but are derived from terrestrial mammals of fairly high organization, belonging to the placental division of the class — animals in which a hairy covering was developed, and with sense-organs, especially that of smell, adapted for living on land ; animals, moreover, with four completely developed pairs of limbs on the type of the higher vertebrata, and not of that of fishes. One of the methods by which a land mammal may have been changed into an aquatic one is clearly shown in the stages which still survive among the carnivora. The seals are obviously modifications of the land carnivora, the Otaria, or sea-lions and sea-bears, being cu- riously intermediate. Many naturalists have been tempted to think that the whales represent a still further stage of the same kind of modification. But there is to my mind a fatal objection to this view. The seal, of course, has much in common with the whale, inasmuch as it is a mammal adapted for an aquatic life, but it has been converted to its general fish-like form by the peculiar development of its hind- limbs into instruments of propulsion through the water ; for, though 206 THE POPULAR SCIENCE MONTHLY. the thighs and legs are small, the feet are large and are the special organs of locomotion in the water, the tail being quite rudimentary. In the whales the hind-limbs are aborted and the tail developed into a powerful swimming organ. Now, it is very difficult to suppose that, when the hind-limbs had once become so well adapted to a function so essential to the welfare of the animal as that of swimming, they could ever have become reduced and their action transferred to the tail. It is far more reasonable to suppose that whales were derived from animals with large tails, which were used in swimming, event- ually with such effect that the hind-limbs became no longer neces- sary, and so gradually disappeared. The powerful tail, with lateral cutaneous flanges, of an American species of otter {Pteronura sand- bachii), or the still more familiar tail of the beaver, may give some idea of this member in the primitive Cetacea. As pointed out long ago by Hunter, there are numerous points in the structure of the visceral organs of the Cetacea far more resembling those of the Ungulata than the Carnivora. These are the complex stomach, simple liver, respiratory organs, and especially the reproduc- tive organs and structures relating to the development of the young. I can not help thinking that some insight has been shown in the com- mon names attached to one of the most familiar of Cetaceans by those whose opportunities of knowing its nature have been greatest — " sea-hog," " sea-pig," or " herring-hog," of our fishermen, Meerschwein of the Germans, corrupted into the French " marsouin," and also "porcpoisson," shortened into "porpoise." A difficulty that might be suggested in the derivation of the Cetacea from the Ungulata, arising from the latter being at the present day mainly vegetable-feeders, is not great, as the primitive ungulates were probably omnivorous, as their least modified descendants, the pigs, are still ; and the aquatic branch might easily have gradually become more and more piscivorous, as we know, from the structure of their bones and teeth, the purely terrestrial members have become by degrees more exclusively grami- nivorous. One other consideration may remove some of the difficulties that may arise in contemplating the transition of land mammals into whales. The Gangetic dolphin (Platanista) and the somewhat related Inia of South America, which retain several rather generalized mammalian characters, and are related to some of the earliest known European Miocene forms, are both to the present day exclusively fluviatile, being found in the rivers they inhabit almost up to their very sources, more than a thousand miles from the sea. May this not point to the fresh- water origin of the whole group, and thus account for their otherwise inexplicable absence from the Cretaceous seas ? THE FUEL OF THE FUTURE. 207 THE FUEL OF THE FUTUEE. By GEORGE WAEDMAN. THE practical application of natural gas, as an article of fuel, to the purpose of manufacturing glass, iron, and steel, promises to work a revolution in the industrial interests of America — promises to work a revolution ; for, notwithstanding the fact that, in many of the largest iron, steel, and glass factories in Pittsburg and its vicinity, natural gas has already been substituted for coal, the managers of some such works are shy of the new fuel, mainly for two reasons : 1. They doubt the continuity and regularity of its supply ; 2. They do not deem the difference between the price of natural gas and coal sufficient, as yet, to justify the expenditure involved in the furnace changes necessary to the substitution of the one for the other. These two objections will doubtless disappear with additional experience in the production and regulation of the gas-supply, and with enlarged competition among the companies engaging in its transmission from the wells to the works. At present the use of natural gas as a sub- stitute for coal in the manufacture of glass, iron, and steel, is in its infancy. Natural gas is as ancient as the universe. It was known to man in prehistoric times, we must suppose, for the very earliest historical reference to the Magi of Asia records them as worshiping the eternal fires which then blazed, and still blaze, in fissures of the mountain- heights overlooking the Caspian Sea. Those records appertain to a period at least GOO years before the birth of Christ ; but the Magi must have lived and woi'shiped long anterior to that time. Zoroaster, reputed founder of the Parsee sect, is placed contem- porary with the prophet Daniel, from 2500 to 600 b. c. ; and, al- though Daniel has been doubted, and Zoroaster may never have seen the light, the fissures of the Caucasus have been flaming since the earliest authentic records. Tho Parsees (Persians) did not originally worship fire. They believed in two great powers — the Spirit of Light, or Good, and the Spirit of Darkness, or Evil. Subsequent to Zoroaster, when the Per- sian Empire rose to its greatest power and importance, overspreading the west to the shores of the Caspian and beyond, the tribes of the Caucasus suffered political subjugation ; but the creed of the Magi, founded upon the eternal flame-altars of the mountains, proved suffi- ciently vigorous to transform the Parseeism of the conquerors to the fire-worship of the conquered. About the beginning of the seventh century of the Christian era, the Grecian Emperor Heraclius overturned the fire-altars of the Magi at Baku, the chief city on the Caspian, but the fire- worshipers were 208 THE POPULAR SCIENCE MONTHLY. not expelled from the Caucasus until the Mohammedans subjugated the Persian Empire, when they were driven into the Rangoon, on the Irrawaddy, in India, one of the most noted petroleum-producing dis- tricts of the world. Petroleum and natural gas are so intimately related that one would hardly dare to say whether the gas proceeds from petroleum or the petroleum is deposited from the gas. It is, however, safe to assume that they are the products of one material, the lighter element sepa- rating from the heavier under certain degrees of temperature and pressure. Thus, petroleum may separate from the gas as asphaltum separates from petroleum. But some speculative minds consider nat- ural gas to be a product of anthracite coal. The fact that the great supply-field of natural gas in Western Pennsylvania, New York, West Virginia, and Eastern Ohio, is a bituminous and not an anthracite region, does not, of itself, confute that theory ; as the argument for it is, that the gas may be tapped at a remote distance from the source of supply, and, whereas anthracite is not a gas-coal, while bituminous is, we are told to suppose that the gas which once may have been a component part of the anthracite was long ago expelled by Nature, and has since been held in vast reservoirs with slight waste, awaiting the use of man. That is one theory ; and upon that supposition it is suggested that anthracite may exist below the bituminous beds of the region lying between the Alleghany Mountains and the Great Lakes. Another theory is, that natural gas is a product of the sea-weed depos- ited in the Devonian stratum. But, leaving modern theories on the origin of natural gas and petroleum, we may suppose the natural gas- jets now burning in the fissures of the Caucasus to have started up in flames about the time when, according to the Old Testament, Noah descended from Mount Ararat, or very soon thereafter. In the lan- guage of modern science it would be safe to say that those flames sprang up when the Caucasus range was raised from beneath the sur- face of the universal sea. The believer in biblical chronology may say that those fires have been burning for four thousand years — the geologist may say for four millions. We know that Alexander the Great penetrated to the Caspian ; and in Plutarch we read : " Hence [Arbela] he marched through the province of Babylon [Media?], which immediately submitted to him, and in Ecbatana [?] was much surprised at the sight of the place where fire issues in a continuous stream, like a spring of water, out of a cleft in the earth, and the stream of naphtha, which not far from this spot flows out so abundantly as to form a large lake. This naphtha, in other respects resembling bitumen, is so subject to take fire that, before it touches the flame, it will kindle at the very light that surrounds it, and often inflame the intermediate air also. The barbarians, to show the power and nature of it, sprinkled the street that led to the king's lodgings with little drops of it, and, when it was THE FUEL OF THE FUTURE. 209 almost night, stood at the farther end with torches, which being ap- plied to the moistened places, the first taking fire, instantly, as quick as a man could think of it, it caught from one end to another in such manner that the whole street was one continued flame. Among those who used to wait upon the king, and find occasion to amuse him, when he anointed and washed himself, there was one Athenophanus, an Athenian, who desired him to make an experiment of the naphtha upon Stephanus, who stood by in the bathing-place, a youth with a ridiculously ugly face, whose talent was singing well. ' For,' said he, ' if it take hold of him, and is not put out, it must undeniably be allowed to be of the most invincible strength.' The youth, as it happened, readily consented to undergo the trial, and, as soon as he was anointed and rubbed with it, his whole body bi'oke out into such a flame, and was so seized by the fire, that Alexander was in the greatest perplexity and alarm for him, and not without reason ; for nothing could have prevented his being consumed by it if, by good chance, there had not been people at hand with a great many vessels of water for the service of the bath, with all which they had much ado to extinguish the fire ; and his body was so burned all over that he was not cured of it a good while after. And thus it is not with- out some plausibility that they endeavor to reconcile the fable to truth, who say this was the drug in the tragedies with which Medea anointed the crown and veils which she gave to Creon's daughter." An interesting reference to the fire-worshipers of the Caucasus is contained in the " History of Zobeide," a tale of the wonderful Arabian Nights Entertainment. It runs thus : " I bought a ship at Balsora, and freighted it ; my sisters chose to go with me, and we set sail with a fair wind. Some weeks after we cast anchor in a harbor which presented itself, with intent to water the ship. As I was tired with having been so long on board, I landed with the first boat, and walked up into the country. I soon came in sight of a great town. When I arrived there I was much surprised to see vast numbers of people in different postures, but all immovable. The merchants were in their shops, the soldiery on guard ; every one seemed engaged in his proper avocation, yet all were become as stone. ... I heard the voice of a man reading Al Koran. . . . Being curious to know why he was the only living creature in the town, ... he proceeded to tell me that the city was the metropolis of a kingdom now governed by his father ; that the former king and all his subjects were Magi, worshipers of fire and of Nardoun, the ancient king of the giants who rebelled against God. ' Though I was born,' continued he, ' of idolatrous parents, it was my good fortune to have a woman gov- erness who was a strict obseiwer of the Mohammedan religion. She taught me Arabic from Al Koran ; by her I was instructed in the true religion, which I would never afterward renounce. About three years ago a thundering voice was heard distinctly throughout the city, say- VOL. XXTII. — 14 2io THE POPULAR SCIENCE MONTHLY. ing, "Inhabitants, abandon the worship of Nardoun and of fire, and worship the only true God, who showeth mercy ! " This voice was heard three years successively, but no one regarded it. At the end of the last year all the inhabitants were in an instant turned to stone. I alone was preserved.' " In the foregoing tale we doubtless have reference to the destruc- tion of Baku, on the Caspian (though to sail from Balsora to Baku is impossible), and the driving away into India, by the Arabs under Caliph Omar, of all who refused to renounce fire-worship and adopt the creed of the Koran. The turning of the refractory inhabitants into stone is probably the Arabian story-teller's figurative manner of referring to the finding of dead bodies in a mummified condition. It is known that the Egyptians made use of bitumen, in some form, in the preservation of their dead, a fact with which the Arabians were familiar. As the Magi held the four elements of earth, air, fire, and water to be sacred, they feared to either bury, burn, sink, or expose to air the corrupting bodies of their deceased. Therefore, it was their practice to envelop the corpse in a coating of wax or bitumen, so as to hermetically seal it from immediate contact with either of the four sacred elements. Hence the idea of all the bodies of the Magi left at Baku being turned to stone, while only the true believer in Mohammed remained in the flesh. Marco Polo, the famous traveler of the thirteenth century, makes reference to the burning jets of the Caucasus, and those fires are known to the Russians as continuing in existence since the army of Peter the Great wrested the regions about the Caspian from the modern Per- sians. The record of those flaming jets of natural gas is thus brought down in an unbroken chain of evidence from remote antiquity to the present day, and they are still burning. Numerous Greek and Latin writers testify to the known existence of petroleum about the shores of the Mediterranean two thousand years ago. More modern citations may, however, be read with equal interest. In the " Journal of Sir Philip Skippon's Travels in France," in 16G3, we find the following curious entries : " We stayed in Grenoble till August 1st, and one day rode out, and, after twice fording the river Drac (which makes a great wash) at a league's distance, went over to Pont de Clef, a large arch across that river, where we paid one sol a man ; a league further we passed through a large village called Vif, and about a league thence by S. Bathomew, another village, and Chasteau Bernard, where we saw a flame breaking out of the side of a bank, which is vulgarly called La Fountaine qui Brule / it is by a small rivulet, and sometimes breaks out in other places ; just before our coming some other strangers had fried eggs here. The soil hereabouts is full of a black stone, like our coal, which, perhaps, is the continual fuel of the fire. . . . Near Peroul, about a league from Montpelier, we saw a boiling fountain (as they THE FUEL OF THE FUTURE. 211 call it), that is, the water did heave up and bubble as if it boiled. This phenomenon in the water was caused by a vapor ascending out of the earth through the water, as was manifest, for if that one did but dig anywhere near the place, and pour water upon the place new digged, one should observe in it the like bubbling, the vapor arising not only in that place where the fountain was, but all thereabout ; the like vapor ascending out of the earth and causing such ebullition in water it passes through hath been observed in Mr. Hawkley's ground, about a mile from the town of Wigan, in Lancashire, which vapor, by the application of a lighted candle, paper, or the like, catches fire and flames vigorously. Whether or not this vapor at Peroul would in like manner catch fire and burn I cannot say, it coming not in our minds to make the experiment. . . . At Gabian, about a day's journey from Montpelier, in the way to Beziers, is a fountain of petroleum. It burns like oil, is of a pungent scent, and a blackish color. It distills out of several places of the rock all the year long, but most in the summer time. They gather it up with ladles and put it in a barrel set on end, which hath a spiggot just at the bottom. When they have put in a good quantity they open the spiggot to let out the water, and when the oil begins to come presently stop it. They pay for the farm of this fountain about fifty crowns per annum. We were told by one Monsieur Beaushoste, a chymist in Montpelier, that petroleum was the very same with oil of jet, and not to be distinguished from it by color, taste, smell, consistency, virtues, or any other accident, as he had by experience found upon the coast of the Mediterranean Sea, in several places, $s at Berre, near Martague, in Provence ; at Messina, in Sicily, etc." In Harris's " Voyages," published in 1764, an article on the empire of Persia thus refers to petroleum : "In several parts of Persia we meet with naphtha, both white and black ; it is used in painting and varnish, and sometimes in physic, and there is an oil extracted from it which is applied to several uses, The most famous springs of naphtha are in the neighborhood of Baku, which furnish vast quantities, and there are also upwards of thirty springs about Shamasky, both in the province of Schirwan. The Per- sians use it as oil for their lamps and in making fireworks, of which they are extremely fond, and in which they are great proficients." Petroleum has long been known to exist also in the northern part of Italy, the cities of Parma and Genoa having been for many years lighted with it. In the province of Szechuen, China, natural gas is obtained from beds of rock-salt at a depth of fifteen to sixteen hundred feet. Being brought to the surface, it is conveyed in bamboo tubes and used for lighting as well as for evaporating water in the manufacture of salt. It is asserted that the Chinese used this natural gas for illuminating purposes long before gas-lighting was known to the Europeans. Re- 212 THE POPULAR SCIENCE MONTHLY. membering the unprogressive character of Chinese arts and industries there is ground for the belief that they may have been using this nat- ural gas as an illuminant these hundreds of years. In the United States the existence of petroleum was known to the Pilgrim Fathers, who doubtless obtained their first information of it from the Indians, for whom, in New York and Western Pennsylvania, it was called Seneka-oil. It was otherwise known as "British " oil and oil of naphtha, and was considered " a sovereign remedy for an inward bruise." The record of natural gas in this country is not so complete as that of petroleum, but we learn that an important gas-spring was known in West Bloomfield, N. Y., seventy years ago. In 1864 a well was sunk to a depth of three hundred feet upon that vein, from which a suffi- cient supply of gas was obtained to illuminate and heat the city of Rochester (twenty-five miles distant) it was supposed. But the pipes which were laid for that purpose, being of wood, were unfitted to withstand the pressure, in consequence of which the scheme was aban- doned ; but gas from that well is now in use as an illuminant and as fuel both in the town of West Bloomfield and at Honeoye Falls. The village of Fredonia, N. Y., has been using natural gas in lighting the streets for thirty years or thereabout. On Big Sewickley Creek, in Westmoreland County, Pa., natural gas was used for evaporating water in the manufacture of salt thirty years ago, and gas is still issu- ing at the same place. Natural gas has been in use in several localities in Eastern Ohio for twenty-five years, and the wells are flowing as vigorously as when first known. It has also been in use in West Vir- ginia for a quarter of a century, as well as in the petroleum region of Western Pennsylvania, where it has long been utilized in generating steam for drilling oil-wells. In 1826 the "American Journal of Science" contained a letter from Dr. S. P. Hildreth, who, in writing of the products of the Muskin- gum (Ohio) Valley, said : " They have sunk two wells, which are now more than four hundred feet in depth ; one of them affords a very strong and pure salt-water, but not in great quantity ; the other dis- charges such vast quantities of petroleum, or, as it is vulgarly called, 'Seneka-oil,' and besides is so subject to such tremendous explosions of gas, as to force out all the water and afford nothing but gas for sev- eral days, that they make little or no salt." The value of the foregoing references is to be found in the testi- mony they offer as to the duration of the supply of natural gas. Whether we look to the eternal flaming fissures of the Caucasus, or to New York, Pennsylvania, and Ohio, there is much to encourage the belief that the flow of natural gas may be, like the production of petroleum, increased rather than diminished by the draughts made upon it. Petroleum, instead of diminishing in quantity by the mill- ions of barrels drawn from Western Pennsylvania in the last quarter THE FUEL OF THE FUTURE. 213 of a century, seems to increase, greater wells being known in 1884 than in any previous year, and prices having fallen from two dollars per bottle for " Seneka-oil " to sixty cents per barrel for the same arti- cle under the name of crude petroleum. Hence we may assume that, as new pipe-lines are laid, the supply of natural gas available for use in the great manufacturing district of Pittsburg and vicinity will be in- creased, and the price of this fuel diminished in a corresponding ratio. Natural gas is now supplied in Pittsburg at a small discount on the actual cost of coal used last year in the large manufacturing establish- ments, an additional saving being made in dispensing with firemen and avoidance of hauling ashes from the boiler-room. It is supplied, for domestic purposes, at twenty cents per one thousand cubic feet, which is not cheaper than coal in Pittsburg, but it is a thousand per cent cleaner ; and in that respect it promises to prove a great blessing, not only to those who can afford to use it, but to the community at large, in the hope held out that the smoke and soot nuisance may be abated in part, if not wholly subdued, and that gleams of sunshine there may become less phenomenal in the future than they are at the present time. Twenty cents per thousand feet is too high a price to bring gas into general use for domestic purposes in a city where coal is cheap. Ten cents would be too much, and no doubt five cents per thousand would pay a profit. The fact is, the dealers in natural gas appear to be somewhat doubtful of the continuity of supply, and anxious to get back the cost of wells and pipes in one year, which, if successful, would be an enormous return on the investment. There are objections to the use of natural gas by mill-operators — that it costs too much, and that the continuity of the supply is uncer- tain ; by heads of families, that it is odorless, and, in case of leakage from the pipes, may fill a room and be ready to explode without giv ing the fragrant warning offered by common gas. Both of these ob- jections will probably disappear under the experience that time must furnish. More wells and tributary lines will lessen the cost and tend to regulate the pressure for manufacturers. Cut-offs and escape-pipes outside of the house will reduce the risk of ex2?losions within. The danger in the house may also be lessened by providing healthful ven- tilation in all apartments wherein gas shall be consumed. This subject of the ventilation of rooms in which common gas is ordinarily used is beginning to attract attention. It is stated, upon scientific authority, that a jet of common gas, equivalent to twelve sperm-candles, consumes 5'45 cubic feet of oxygen per hour, producing 3-21 feet of carbonic-acid gas, vitiating, according to Dr. Tidy's " Handbook of Chemistry," 348-25 cubic feet of air. In every five cubic feet of pure air in a room there is one cubic foot of oxygen and four of nitrogen. Without oxygen human life, as well as light, would become extinct. It is asserted that one common gas-jet consumes as much oxygen as five persons. 214 THE POPULAR SCIENCE MONTHLY. Carbonic-acid gas is the element which, in deep mines and vaults, causes almost instant insensibility and suffocation to persons subjected to its influences, and instantly extinguishes the flame of any light lowered into it. The normal quantity of this gas contained in the air we breathe is *04 ; one per cent of it causes distress in breathing ; two per cent is dangerous ; four per cent extinguishes life, and four per cent of it is contained in air expelled from the lungs. According to Dr. Tidy's table, each ordinary jet of common gas contributes to the air of a room sixteen by ten feet on the sides and nine feet high, con- taining 1,440 cubic feet of air, twenty-two per cent of carbonic-acid gas, which, continued for twenty hours without ventilation, would reach the fatal four per cent. Professor Huxley gives, as a result of chemical analyses, the fol- lowing table of ratio of carbonic-acid gas in the atmosphere at the points named : On the Thames, at London -0343 In the streets of London -0380 Top of Ben Nevis -0327 Dress circle of Haymarket Theatre (11.30 p. m.) -0757 Chancery Court (seven feet from the ground) *1930 From working mines (average of 339 samples) '7852 Largest amount in a Cornish mine 2'0500 In addition to the consumption of oxygen and production of car- bonic acid by the use of common gas, the gas itself, owing to defect- iveness of the burner, is projected into the air. Now, considering the deleterious nature of all illuminating gases, the reasons for perfect ventilation of rooms in which natural gas is used for heating and culinary purposes are self-evident, not alone as a protection against explosions, but for the health of the occupants of the house, remem- bering that a larger supply of oxygen is said to be necessary for the perfect combustion of natural than of common gas. Carbonic oxide, formed by the consumption of carbon, with an in- sufficient supply of air, is the fatal poison of the charcoal-furnace, not infrequently resorted to, in close rooms, as a means of suicide. The less sufficient the air toward perfect combustion, the smaller the quan- tity of carbonic acid and the greater the amount of carbonic oxide. That is to say, at the time of ignition the chief product of combus- tion is carbonic oxide, and, unless sufficient air be added to convert the oxide to carbonic acid, a decidedly dangerous product is given off into the room. Yet, by means of a flue to carry off the poisonous gases from burning jets, the combustion of gas, creating a current, is made an aid to ventilation. Unfortunately, this important fact, if commonly known, is not much heeded by heads of families or builders of houses. But in any large community where gas comes into general use as an article of fuel, this fact will gradually become recognized and re- spected. THE FUEL OF THE FUTURE. 215 The property of indicating the presence of very minute quantities of gas in a room is claimed for an instrument recently described by C. von Jahn, in the " Revue Industrielle." This is a porous cup, in- verted and closed by a perforated rubber stopper. Through the perfo- ration in the stopper the interior of the cup is connected with a press- ure-gauge containing colored water. It is claimed that the diffusion of gas through the earthenware raises the level of the water in the gauge so delicately that the presence of one half of one per cent of gas may be detected by it. Other instruments of a slightly different character are credited by their inventors with most sensitive power of indicating gas-leakages, but their practical efficiency remains to be demonstrated. An automatic cut-off for use outside of houses in which natural gas is consumed has been invented, but this writer knows nothing of either its mode of action or its effectiveness. The great economic question, however, connected with the use of natural gas is, How will it affect the industrial interests of the coun- try ? There are grounds for the belief that a sufficient supply of natu- ral gas may be found in the vicinity of Pittsburg to reduce the cost of fuel to such a degree as to make competition in the manufacture of iron, steel, and glass, in any part of the country where coal must be used, out of the question. Such a condition of affairs would probably result in driving the great manufacturing concerns of the country into the region where natural gas is to be obtained. That may be any- where from the western slope of the Alleghanies to Lake Erie or to Lake Michigan. And, if the cost of producing iron, steel, and glass can be so cheapened by the new fuel, the tariff question may undergo some important modification in politics. For, if the reduction in the cost of fuel should ever become an offset to the lower rate of wages in Europe, the manufacturers of Pennsylvania, who have long been the chief support of the protective policy of the country, may lose their present interest in that question, and leave the tariff to shift for itself elsewhere. It should be remembered that natural gas is not, as yet, much cheaper than coal in Pittsburg. But it may safely be as- sumed that it will cheapen, as petroleum has done, by a development of the territory in which it is known to exist in enormous quantities. It is quite possible that, instead of buying gas, many factories will bore for it with success, or remove convenient to its natural sources, so that a gas-well may ultimately become an essential part of the "plant" of a mill or factory. Even now coal can not compete with gas in the manufacture of window-glass, for, the gas being free from sulphur and other impurities contained in coal, produces a superior quality of glass ; so that in this branch of industry the question of superiority seems already settled. Having said thus much of an industry now in its infancy but prom- ising great growth, I submit tables of analyses of common and of the natural or marsh gas, the latter from a paper recently prepared by a 2l6 THE POPULAR SCIENCE MONTHLY CM O • CO • . o ,S91BA\ . ^JH • CD • OS • • o J^ t^nog 'euiin ; jo ; ; 6 I « ; o -I«03 0] J3AU>Ig * OS * c i-H Oi O • tj( • CM O CO i- • ^ r-i o ^ -jamreo hb£ja\ ' © ■* ' cb CO o nj papnpoo bbj) co ... c CO OS • -CO -OS -CO C ^ -BBS osid OS O • -I-H - • o os Jr~ • CO _. -panojo • CO • i— 1 • CO 1— t • o t-i qsjuj^ may bb*) £~ CO O O c o r— I ■»A •piou oiuoqauo fcRJtnO stjaiJoy iiuoo jod 98- SI put; uaiioajiu jo sort -ijirenb j|t!uis qqAi 'st;8-qs.it!tu A*naiuQ o *3II!A o .

THE FUEL OF THE FUTURE. 217 committee of the Engineers' Society of Western Pennsylvania, and for the use of which I am indebted to that association : COMMON GAS. Hydrogen 46-0 Light carbureted hydrogen (marsh-gas) 395 Condensible hydrocarbon 3"8 Carbonic oxide.. Y'5 " acid 0-G Aqueous vapor 2*0 Oxygen 01 Nitrogen 0"5 100-00 Natural gas is now conveyed to Pittsburg through four lines of 5f-inch pipe, and one line of eight-inch pipe. A line of ten-inch pipe is also being laid. The pressure of the gas at the wells is from 150 to 230 pounds to the square inch. As the wells are on one side eighteen and on the other about twenty-five miles distant, and as the consump- tion is variable, the pressure at the city can not be given. Greater pressure might be obtained at the wells, but this would increase the liability to leakage and bursting of pipes. For the prevention of such casualties safety-valves are provided at the wells, permitting the escape of all superfluous gas. The enormous force of this gas may be appre- ciated from a comparison of, say, 200 pounds pressure at the wells with a two-ounce pressure of common gas for ordinary lighting. The amount of natural gas now furnished for use in Pittsburg is supposed to be something like 25,000,000 cubic feet per day ; the ten-inch pipe now laying is estimated to increase the supply to 40,000,000 feet. The amount of manufactured gas used for lighting the same city probably falls below 3,000,000 feet. About fifty mills and factories of various kinds in Pittsburg now use natural gas. It is used for domestic pur- poses in two hundred houses. Its superiority over coal in the manu- facture of window-glass is unquestioned. That it is not used in all the glass-houses of Pittsburg is due to the fact that its advantages were not fully known when the furnaces were fired last summer, and it costs a large sum to permit the furnaces to cool off after being heated for melting. When the fires cool down, and before they are started up again, the furnaces now using coal will doubtless all be changed so as to admit natural gas. The superiority of French over American glass is said to be due to the fact that the French use wood and the Americans coal in their furnaces, wood being free from sulphur, phosphorus, etc. The substitution of gas for coal, while not increas- ing the cost, improves the quality of American glass, making it as nearly perfect as possible. While the gas is not used as yet in any smelting-furnace nor in the Bessemer converters, it is preferred in open-hearth and crucible steel furnaces, and is said to be vastly superior to coal for puddling. 2i 8 THE POPULAR SCIENCE MONTHLY. The charge of a puddling-furnace, consisting of 500 pounds of pig- metal and eighty pounds of " fix," produces with coal-fuel 490 to 500 pounds of iron. With gas for fuel, it is claimed that the same charge will yield 520 to 530 pounds of iron. In an iron-mill of thirty fur- naces, running eight heats each for twenty-four hours, this would make a difference in favor of the gas of, say, 8 X 30 X 25 = 6,000 pounds of iron per day. This is an important item of itself, leaving out the cost of firing with coal and hauling ashes. For generating steam in large establishments, one man will attend a battery of twelve or twenty boilers, using gas as fuel, keep the pressure uniform, and have the fire-room clean as a parlor. For burn- ing brick and earthenware, gas offers the double advantage of free- dom from smoke and a uniform heat. The use of gas in public bak- eries promises the abolition of the ash-box and its accumulation of miscellaneous filth, which is said to often impregnate the " sponge " with impurities. In short, the advantages of natural gas as a fuel are so obvious to those who have given it a trial, that the prediction is made that, should the supply fail, many who are now using it will never return to the consumption of crude coal in factories, but, if necessary, convert it or petroleum into gas at their own works. It seems, indeed, that, until we shall have acquired the wisdom en- abling us to conserve and concentrate the heat of the sun, gas must be the fuel of the future. USE OF SULPHUROUS DISINFECTANTS. By GASTON TISSANDIEE. AMONG the most convenient and efficacious substances to be used for purposes of disinfection are sulphurous acid and bisulphide of carbon. The question of the merits of these substances and the advantages of using them was recently considered, in the "Journal de Pharmacie et de Chimie," by M. Alfred Riche, who said : " M. Dujar- din-Beaumetz recently requested the concurrence of MM. Pasteur and Roux in instituting new experiments on the value of disinfectants, and has just published the results of the same in the ' Bulletin ' of the Academy of Medicine. Two rooms of about a hundred cubic metres capacity were selected in the wooden barracks attached to the hoj)ital Cochin. The walls of these rooms, made of jointed planks, gave pas- sage to the air through numerous cracks, although the precaution had been taken of stopping the larger ones with paper. Each of the rooms was furnished with a bed, the usual furniture, and cloths of different colors. Bromine, chlorine, and sulphate of nitrosyle were successively rejected. Three sources of sulphurous acid were experi- USE OF SULPHUROUS DISINFECTANTS. 219 mented upon — the combustion of sulphur, liquefied sulphurous acid, and the combustion of bisulphide of carbon. The room was closed for twenty-four hours. Tubes containing culture-infusions sowed with different proto-organisms, especially the comma microbe described by Koch, were placed in rooms, together with tubes containing vac- cine lymph. After each experiment the tubes were taken to M. Pasteur's laboratory, and there compared with other tubes used as tests. The process of the combustion of sulphur is the simplest and cheapest. To perform this combustion, it is sufficient to set on the floor a sheet-iron plate — a large potsherd on the ground gives a satis- factory result — on which is placed a furnace of bricks and mortar, or better, one of those small, nearly square furnaces of fire-clay recom- mended by M. Pasteur, twenty-five centimetres long and twenty centi- metres wide, and having the sides pierced with air-holes. To obtain a complete combustion of the flowers of sulphur, it is necessary to Fia. 1.— Burner for Sxtlphur. take care that the whole surface be evenly burned ; this may be effected by wetting the sulphur with alcohol and inflaming the alcohol. By this method we can burn completely and absolutely as large a quantity as forty or fifty grammes per cubic metre of flowers of sulphur. "With twenty grammes per cubic metre, all of the culture-infusions experi- mented upon were sterilized, except the one containing the carbun- cular (anthrax) bacteria. The activity of the vaccine virus was de- stroyed. The only probable inconveniences involved in the application of this economical process arise from the danger of fire in case the furnace is badly constructed, and from the liability of the metallic objects that may be present to be tarnished. This may take place 220 THE POPULAR SCIENCE MONTHLY from particles of the burning element flying around the room, and, settling on articles of copper and iron, covering them with a sulphur- ous coating. " The process of using liquid anhydrous sulphurous acid in siphons is free from these inconveniences. The siphons contain 750 grammes of the acid, and one of them is efficient for the disinfection of twenty cubic metres of space. In using the siphons a vessel is set in the mid- dle of the room, and is put in communication with the outside by means of an India-rubber tube passing through a hole in the door. The door having been closed, the orifice of the siphon is inserted into the India-rubber tube, and, the liquid being let in through it, is freely evaporated in the air of the room. This process is very convenient ; it avoids the danger of fire, and does not affect metallic objects ; and the penetrative force of sulphurous acid thus administered appears to be greater than that of the acid obtained by bui-ning sulphur. The only drawback to its use is the high cost. The siphons are sold to the general public for a dollar each, but can be bought in large quan- Fig. 2.— M. Ckiandi Bet's Burner fob Bisulphide of Carbon. tities for half that price. Thus the expense of disinfecting a room of one hundred cubic metres with this preparation would be from two and a half to five dollars." The process of the combustion of bisulphide of carbon was sug- USE OF SULPHUROUS DISINFECTANTS. 221 gested by M. E. Peligot ; and all danger in employing it is obviated in the new burner invented by M. Ckiandi Bey, engineer. This ap- paratus is illustrated, with a view of its interior arrangement, in Fig. 2 ; and a more detailed explanation of its parts can be obtained from the examination of Fig. 3. M. Ckiandi's burner is composed of an exterior receiver of tinned copper, A B C D, containing an interior vessel, I H E F, to the sides of which are fixed three siphons, R S. To put it in operation, the cylin- drical tube, KLMN, is placed in the interior vessel ; sulphide of car- bon is poured in up to the level a a, and the exterior receiver is then filled with water up to the level b b. By means of the siphons the water Fig. 3.— M. Ckiandi Bet's Burner, Sectional View. penetrates into the interior vessel, presses upon the sulphide of carbon, which is heavier than it, and drives it in the interior tube up to the level a' a', where it is taken up by a cotton wick, which is lighted. The upper end of the tube is crowned with a chimney, P Q, to facili- tate the draught. The combustion of the sulphide of carbon may be increased or slackened at will by raising or lowering the level, b b, of the water in the external receiver ; and this facility will be found of advantage in many cases. The burner is placed in the room to be disinfected and lit, when the room is evacuated and shut up tight. When all the sulphide of carbon has been burned, its place is taken by water, and the lamp goes out of itself ; in the mean time the burning goes on with great regu- larity, and without any danger. About two and a half kilogrammes (six and a quarter pounds) of sulphide of carbon are sufficient for a room of a hundred cubic metres. The process is effective and economical enough ; for sulphide of carbon is sold commercially for fifty centimes (about ten cents) per kilogi-amme, which gives about twenty-five cents 222 THE POPULAR SCIENCE MONTHLY. as the price of disinfecting a room of a hundred cubic metres. The burner costs ten dollars, but it will last for a very long time. This process is evidently practicable and convenient. It does not tarnish metallic objects, and furnishes a continuous, slow, and regular disen- gagement of the disinfecting gas. — Translated for the Popular Sci- ence Monthly from La Nature. -+•+- THE MEDITERRANEAN OF CANADA. By J. MACDONALD OXLEY. IN the month of February last a report was laid before the Parlia- ment of Canada detailing the results of an expedition dispatched by the Government of that country particularly for the purpose of in- quiring into the navigability of Hudson Strait and Bay, and, at the same time, of gathering information concerning the resources of that region, and its availability as a field for settled habitation. This report represents the first properly organized attempt that has ever been made to pierce the secrets of Hudson Bay for the public benefit. It is at first blush not easy to understand why this mighty expanse of water, occupying the peculiarly important position that it does, should remain for so many generations comparatively unexplored, and wholly unutilized, except as a hunting-ground for a few New Bedford whalers, or a medium of easy communication between some half-dozen scattered factories of the Hudson Bay Company. Although called a bay, it is really an inland sea, 1,000 miles in length by 600 in width, having thus an area of about 500,000 square miles, or quite half that of the Mediterranean. It drains an expanse of country spreading out more than 2,000 miles from east to west, and 1,500 from north to south, or an area of 3,000,000 square miles. Into its majestic waters pour feeders which take their rise in the Rocky Mountains on the west and in Labrador on the east, while southward it stretches out its river-roots away below the 49th parallel until they tap the same lake-source which sends a stream into the Gulf of Mexico. Despite its distance north- ward, its blue waves are never bound by icy fetters, and its broad gate- way to the Atlantic is certainly navigable four months out of the year, and possibly all the year round to properly equipped steamships. Its depths abound in finny wealth, from the mammoth whale to the tiny caplin. Its shores are serrated by numerous streams, some navigable for long distances inland, and all stocked with the finest of fresh-water fish, and clothed as to their banks with valuable timber ready for the lumberman's axe. Its islands are rich in mineral ore of many kinds. The country whose margin its tides lave is well adapted for tillage and pasturage, while all around the region swarms with animals and birds THE MEDITERRANEAN OF CANADA. 223 whose flesh or fur renders their chase a highly lucrative employment. How comes it, then, that, for all this superabundant endowment, the only population outside the wandering bands of Eskimos and native Indians to be found there to-day gathers in little circles around the company's forts which dot the shore at immense intervals? The explanation of this apparent enigma is not far to seek. It lies simply in the fact that, until little more than a decade ago, Hudson Bay and vicinity was the subject of a monopoly, which effectually ex- cluded from it all but the employes of a single corporation. It was first visited in 1610 by Henry Hudson, who, after giving his name to the Hudson River, in his rude little bark, well named Discovery, daunt- lessly pushed his way thither in search of the mythical northwest pas- sage to the Pacific, and made it both his imperishable monument and his grave. The stories that his mutinous crew took home with them did not prevent other vessels being dispatched on the same hopeless quest, and, if these latter failed to find the northwest passage, they at all events found sufficient cause for the Hudson Bay Company being founded in 1668. This astute corporation, easily obtaining a grant of the bay and its environing territory, together with the most extensive powers from a king who knew nothing of its value, and cared less, forthwith set about excluding all possible rivals from their invaluable fur-preserve. For half a century or more they had a serious obstacle to the execution of their laudable design in the presence of the French, and the bay became the theatre of many a hard-fought conflict. It was not until, by the Treaty of Utrecht in 1713, the whole of Hudson Bay was ceded to the British, that the company were left to the undisputed possession of their vast estate — the most stupendous landed property ever owned by one corporation, embracing, as it then did, the entire Northwest of Canada. As the day for violence had gone by, they resorted to a subtler but incomparably more effective method of keeping the country to themselves. The most ingeniously false and distorted accounts were sedulously spread abroad concerning this region. According to them, it was a land of eternal snow and ice, utterly unfit for human settlement. The perils of the passage through the strait were grossly magnified. Preposterous tales were circulated as to the rigors of the climate, the fierceness of the wild animals, and the barbarous character of the inhabitants. The company's efforts were crowned with the most gratifying success. Decade after decade slipped by, and they were still in unquestioned possession, and proba- bly would have continued so to this day, but for their having been bought out in 1870 for the tidy sum of £300,000, by the Canadian Government, to whom, with some reservation, they transferred all their real estate. With the change of ownership came a complete change in policy. Under the new regime, the great object held in view was no longer to keep the country a solitude, unbroken by the hum of human life, but 224 THE POPULAR SCIENCE MONTHLY. to ascertain in how far it might be available as a field for settlement. In fulfillment of this policy, Dr. Bell, Assistant Director of the Geo- logical Survey, was sent up there with an exploring party for six suc- cessive seasons, and his observations constitute some of the most inter- esting portions of the reports of that survey. The vast importance of this region rapidly dawned upon the public mind, when it became known that here was an immense range of country, having a temperate climate, a fertile soil, and boundless wealth in forest and mine, await- ing the long-delayed advent of the farmer, the lumberman, and the miner. And not only so, but the phenomenal development of the great Northwest drew attention to Hudson Bay upon another and even more immediately important ground. Entering as this bay does into the very heart of the continent, and being connected by navigable rivers with a network of great lakes which spreads out until it touches the western boundaries of Mani- toba, the keen-eyed farmers of that fertile province espied in it a hopeful solution of the vital problem how they should most cheaply transport their grain to the markets of the Old World. By reference to a map of the northern hemisphere it will at once be seen that the shortest possible route between the Northwest Territories and Europe lies through Hudson Bay. As the result of careful calculations, it has been ascertained that even the city of Winnipeg, which is situated in the extreme southeastern part of these Territories, is at least eight hundred miles nearer to Liverpool, for instance, by the Hudson Bay route, than by the St. Lawrence, while the difference in favor of the former necessarily increases the farther we advance northwestward. If, as Dr. Bell has so clearly pointed out, we take the central point of the agricultural lands of the Northwest, we shall find that the distance from it to Winnipeg is about the same as it is to Churchill, the finest harbor in Hudson Bay. Now, the distance between Churchill and Liverpool is a little less (about sixty-four miles) than it is between Montreal and that great entrepot of commerce. The conclusion con- sequently is that, as between the above-named center and Liverpool, there is a saving of the whole distance from Winnipeg to Montreal by the use of Hudson Bay. This saving amounts to no less than twelve hundred and ninety-one miles by way of Lake Superior, and sixteen hundred and ninety-eight miles via Chicago. The translation of miles into dollars and cents is an easy process nowadays, and it has been estimated that the difference in freight in favor of the Hudson Bay route is at least thirty-two cents on each bushel of grain, or, in other words, means an additional profit of over six dollars an acre to the farmers of the West. When this idea had once fairly taken hold of the public mind, a profound interest was awakened, not only throughout Canada, but also in England, where, at the 1880 meeting of the British Association, Sir J. IT. Lefroy, Presi- dent of the Geological Section, hesitated not to affirm that the natural THE MEDITERRANEAN OF CANADA. 225 seaports of that vast interior now thrown open to settlement, Mani- toba, Keewatin, and the other provinces yet unborn, must be sought in Hudson Bay. The mouth of the Churchill River would undoubt- edly be the future shipping-port for the agricultural products of the Northwest, and the route by which immigrants would enter the coun- try. In Canada the subject was brought before Parliament for the first time in 1878, and thenceforth pressed upon its attention every year, until, finally, after a committee had gathered all available infor- mation upon the subject, it was decided, at the session of 1884, to dispatch a fully equipped expedition having for it's main object the determination of the one point upon which the whole question rested, namely, whether the bay and strait might be relied upon as safe and serviceable highways of commerce. It was, of course, a matter of general knowledge that these waters had been plowed by keels for two hundred and seventy-four years back ; that sailing-vessels of all descriptions, from the pinnace of twenty tons to the seventy-four-gun man-of-war, had passed through the strait and spread their white wings all across the bay ; and that Moose Factory had been visited by a supply-ship with unfailing regularity every year since 1735. But facts like these, encouraging as they might be, were not conclusive, because in all cases these vessels had been free to choose their own time for entering and leaving the bay, and they therefore still left the question open as to whether these waters were navigable during a sufficient portion of the year to render possible the development of a great and permanent commerce. In order that there should be suc- cessful shipping-ports upon the bay, there must, of course, be railways leading from the interior to these ports, and these railways must be assured of a profitable volume of business during a good long season, or they would never be built. The expedition, therefore, was charged primarily with the duty of affixing the limits of the period of naviga- tion, and at the same time was instructed to gather as much informa- tion concerning the climate, resources, flora, fauna, and other features of the region as the limited time at its command would permit. On the 22d of July last the steamship Neptune, a wooden vessel, built and equipped with special reference to northern navigation in prosecution of the seal-fishery, set forth from the port of Halifax, with the members of the expedition on board. These were some twenty-six in number, Lieutenant Andrew R. Gocdon, R. N., of the Meteoro- logical Survey of Canada, being in command, and having with him, in the double capacity of geologist and medical officer, Dr. Robert Bell, whose explorations in the vicinity of Hudson Bay have been already referred to. The rest of the party comprised a photographer, eight observers, three carpenters, and twelve station-men. As the observers and station-men were to be left for the winter, they had each of them been carefully examined by medical authority, and pronounced physic- ally well fitted to withstand the rigors of an Arctic climate. TOL. XXVII. — 15 226 THE POPULAR SCIENCE MONTHLY. Sailing up past Capes North and Ray, and thence through the Gulf of St. Lawrence and the Strait of Belle Isle, the Neptune coasted along the Labrador shore until reaching Nain on the 29th, where a pause was made in the hopes of securing fur clothing for those who were to remain out all winter, and also an interpreter. Failing in both objects, but experiencing much kindness at the hands of the Moravian missionaries, one of whose principal stations Nain is, the expedition continued on to Nachvak, arriving there on the 1st of August. On the way icebergs were encountered in great numbers, requiring constant vigilance on board the steamship. At Nachvak, which is a post of the Hudson Bay Company, both the fur clothing and the interpreter were readily obtained. The company's agent informed Lieutenant Gordon that the ice takes over the harbor of Nachvak, which is in latitude 59° 10' north, and longitude 63° 30' west, about the middle of November in each year, and, curious to note, has, for the last seven years, at all events broken up within a day of the 2Gth of June in each year. Off Cape Chudleigh, which is just at the mouth of Hudson Strait, the Neptune was enveloped in a dense fog, which compelled her to lay-to from Sunday until Tuesday morning. Tuesday, however, dawned bright and clear, and, pushing in through Grey Strait, a fine harbor was found that afternoon on the north- western shore of the cape, at the entrance to Ungava Bay. On the shore of this harbor a site was selected for observing station No. 1, and the place named Port Bur well, in compliment to the observer appointed to that station. As the best and briefest method of indi- cating the precise nature of the duties devolving upon these observers who were to spend a long and dreary winter at their posts, we here- with transcribe the instructions with which each wras furnished : Instructions to Officers in charge of Stations in Hudson Bay and Strait. — As the primary object of the whole expedition is to ascertain for what period of the year the strait is navigable, all attention is to be paid to the formation, breaking up, and movements of the ice. Each station is supplied with a sun-dial and time-piece, and the clock is to be tested each day when there is sunshine about noon. A table of corrections is supplied for the reduction of apparent time to local mean time ; to this the difference of time will be applied to 75th meridian, all entries being made in the time of this meridian, and observations will be taken regularly at the following times throughout the year, viz., 3h. 08 m., 7 h. 08 m., 11 h. 08 m., a. m. and p. m. Each morning the sums and means of the observations taken on the previous day will be taken out and checked over ; they will then be entered in the abstract-books supplied for the purpose. After each observation during daylight the observer on duty will take the telescope and carefully examine the strait, writing down at THE MEDITERRANEAN OF CANADA. 227 the time all that he sees, stating direction and (when possible) velocity of tide, movement of ice, if any ; also describe the condition of the ice, whether much broken up, solid field, etc. Tidal Observations. — Each day the time and height of high and low water are to be carefully observed, and during the open season the character of the tide will be carefully noted for two days before and three days after the full and change of the moon. For this purpose a post, marked off in feet and fractions of a foot, is to be placed in the water, at low water in some sheltered spot, if any such be available, and the height of the water noted every half -hour during the rise and fall of one tide on each of these days — the height to be noted most carefully every five minutes during the hour of high water and the same at low water ; the five-minute observations will also be taken for one hour during the most rapid portion of the rise. Special observa- tions of barometric pressure are to be taken in connection with these tidal observations. To check the zero-mark for the tidal-observation post, select a spot on shore from which the horizon line will be projected on the tidal post, and record the reading of this line when seen projected on the post by the observer, whose eye is to be placed at a measured height above the datum-point selected on shore. All remarks in regard to the movements of birds, fish, etc., and also as to the growth of grasses, will be carefully entered. As it is impossible to give to the officers in charge of stations detailed instructions which would be of service in every contingency which might arise, the officers are required to observe and enforce the following rules : (a.) Every possible precaution is to be taken against fire, and, as it is anticipated that the temperature can be maintained considerably above the freezing-point inside the houses, two buckets full of water are always to be kept ready for instant use. (b.) As the successful carrying out of the observations will, in a great measure, depend on the health of the party, the need of exercise is strongly insisted on during the winter months, and also that each member of the party shall partake freely of the lime-juice supplied. (c.) Each party is supplied with a boat, but, unless some emergency requires it, it must be a rule that neither afloat nor ashore must any of the party leave the station for a greater distance than they can be sure of being able to return the same day. (d.) As soon as possible after the houses are completed and the stores all in place, the party will set to work collecting sods, grass, or any other non-conducting material, and before the winter sets in the whole house is to be covered with this, boards overlaid, and snow packed over all ; the assistance of the Eskimos should, if possible, be obtained, and the whole house arched over with snow. 228 THE POPULAR SCIENCE MONTHLY. As will be gathered from the above, the observers' duties, while not onerous, were sufficiently varied and responsible to impart variety and purpose to the otherwise necessarily monotonous and depressing round of existence. It was intended to place station No. 2 on the lower Savage Islands, at the northern entrance to the strait, and nearly opposite to station No. 1, but a succession of stormy weather prevented success in doing so. The expedition proceeded up the strait to Big Island, North Bluff, where station No. 3 was established, and the place christened Ashe Inlet. The Eskimos in the neighborhood seemed highly delighted at the prospect of having white men near them. Station No. 4 was established at Stupart's Bay, Prince of Wales Sound, across the strait from Ashe Inlet ; station No. 5 at Port de Boucherville, Nottingham Island. Other calls were made at Digges Island, near Cape Wolsten- holme ; at Marble Island, south of Chesterfield Inlet, which was found marked by the presence of nineteen graves and a monument to six other persons who had been drowned ; at Churchill, the future Liver- pool of the region ; at York Factory, the present commercial metropo- lis of the bay, whence, after a stay of only one day, the return journey was taken up. The several stations were visited in turn, and the finishing touches were given to the preparations for the long Arctic winter. A second attempt was made to establish a station on Resolu- tion Island. Two bays were examined, in both of which the vessel ran unwarned immediately from deep soundings upon the rocks, and the idea was given up. Finally, the Neptune arrived at Port Burwell, on the 27th of September, where, as at all the other stations, it found the observers well, pleased with their work, and satisfied with their provisioning. Thence the expedition returned to St. John's, New- foundland, where the Neptune was given up to her owner, while the men took passage for Halifax. The course of this expedition having thus been briefly outlined, it now remains to examine into the results so far as they have been detailed, and consider their bearing upon the important problem sought to be solved ; and, first of all, with regard to the navigation of Hudson Strait and Bay. The ice has hitherto been supposed to be the most formidable barrier to the navigation of these waters, but Lieutenant Gordon assures us that under investigation its terror very largely dis- appears. The ice' met with during the cruise of the Neptune could be divided into three classes — each class having a distinctly separate ori- gin— namely, icebergs from the glaciers of Fox Channel, heavy Arctic ice from the channel itself, and ordinary field-ice, being that formed on the shores of the bay and strait. No icebergs were encountered in Hudson Bay, nor were any reported as having been seen there in the past ; but in the strait a good many were seen, principally along the northern shore, where a number were stranded in the coves, while others were met with in mid-channel. Of those seen in the eastern THE MEDITERRANEAN OF CANADA. 229 end of the strait, some had undoubtedly come in from Davis Strait, passing between Resolution Island and East Bluff ; but all of those met to the westward had come from Fox Channel, as observations made by the observer at North Bluff show that an iceberg coming in sight from the westward will pass out of view to the eastward in from three to four tides, showing an easterly set of upward of ten miles a day. In Lieutenant Gordon's opinion, the icebergs seen in Hudson Strait during August and September would form no greater barriers to navigation than do those met with off the Strait of Belle Isle, nor were they more numerous in the former than they frequently are in the latter waters. The field-ice encountered, although it would have compelled an ordinary iron steamer to go dead-slow, gave no trouble to the Neptune, the vessel running at full speed between the pans, and rarely touching one of them. In the harbor at Ashe Inlet the ice came in with the flood-tide, and set so fast that the Eskimos were able to walk off to the ship, although she was at least three quarters of a mile from the shore. On the south shore, also, it was much the same ; but still no ice was met with through which the steamer could not easily and safely force her way. In the center of the strait, to the east of North Bluff, no field-ice was seen at all, while between Stupart Bay and Salisbury Island long strings of ice were frequently seen ; but, as their direction was invari- ably parallel to the vessel's course, it was only necessary to coast round them. On the homeward voyage none of this field-ice was seen at all. It is a point of no small significance that, upon the testimony of the Eskimos, both at Ashe Inlet and Stupart Bay, the quantity of ice in the strait had been very unusual that year, and the ice had never been known to hang to the shores so late in the season. After passing the east end of Salisbury Island the ice got heavier and closer, and when off Nottingham Island the pack was so run to- gether that no attempt was made to force the ship through it. Viewed from a hill on Nottingham, the sea in every direction seemed one vast ice-field, in which four vessels could be noted fast prisoners. This ice was of an altogether different type to that which had been hitherto met. In some cases there were sheets of solid blue ice not less than forty feet in thickness, not a mere aggregation of field-ice, but evi- dently frozen just as it stood. In other places the thickness would be twenty feet, and the general average of the whole field at least five feet. Now, the question as to the origin of this ice, and whether it will be frequently met with in- the strait, is one of paramount impor- tance. Lieutenant Gordon does not consider it possible for ice to form in Fox Channel to a greater thickness than ten feet in a single year, and consequently feels convinced that much of the ice encountered was the accumulation of several years. Ice is well known to be a very poor conductor of heat, and therefore, when once a certain thickness has been formed, the subsequent rate of thickening must be very slow. 2 3o THE POPULAR SCIENCE MONTHLY. The depth to which water will freeze has never yet been determined ; but measurements of the formation of ice which are to be carefully made at the observing-stations will, no doubt, materially assist in a determination of this important question. At Churchill the harbor-ice forms, on an average, about the middle of November, and breaks up about the middle of June, and these two dates may therefore be taken as marking the extreme limits of the season during which that harbor may be used. With regard to the time consumed in making the passage through the strait, it is necessary to note that, had the Neptune gone direct from Cape Chudleigh to Churchill, instead of coasting and working across the strait, there would have been no greater delay on account of the ice than forty-eight hours at the most ; but, at the same time, no ordinary iron steamship, built as the modern freight-carrier is, could have got through the heavier ice without incurring serious risk, if not actual disaster. There is one matter to which Lieutenant Gordon draws attention that will require the serious consideration of mariners navigating these waters, namely, that in working through the strait, especially at the western end, he found the ordinary compass so sluggish as to be prac- tically useless. The Sir William Thomson card, however, worked admirably when properly compensated. The reason of this difficulty with the ordinary compass is that, from the proximity to the magnetic pole, the horizontal directive force of the earth's magnetism, which alone directly affects the compass-needle, is very small compared with the whole magnetic force, and consequently the effect of induced mag- netism in the iron of the shij) on the compass becomes very large in comparison with the direct action above mentioned, the result being that, in an imperfectly compensated compass, the error due to local attraction is very greatly increased. The means of correcting this error in the Sir William Thomson binnacle are perfect and easily mastered, and the system is such that the compass can, after the first voyage or two, be perfectly compensated by using certain proportions of soft-iron bars and magnets as correctors, the proportion having to be determined by actual observation and experiment on the voyage. All steamshijjs making the voyage through the strait, Lieutenant Gordon therefore concludes, should have one of these compasses as a standard, and the captains should familiarize themselves with the methods of correcting them, and, as opportunity offers, take azimuth observations, both stellar and solar. Great caution will have to be observed by all vessels approaching the strait in thick weather, owing to the strong southward current there prevailing, which, during the forty-eight hours the Neptune was lying-to, swept her forty miles out of her course by dead-reckoning, showing that the amount of southerly set exceeds that indicated by the Admiralty directions. Then, again, the tides rise to a consider- THE MEDITERRANEAN OF CANADA. 231 able height, as much as thirty-two feet at springs in some places, and in their fluctuations create tide-races, which have to be taken into con- sideration and carefullv allowed for. Thus at the entrance to Church- ill there is a tide-race, the velocity of which was estimated to be not less than seven knots. In the matter of weather, Hudson Strait would seem to compare very favorably with that great highway of commerce, the Strait of Belle Isle, as the following table, which is for the month of August, clearly indicates : Number of days on which fog is recorded Approximate number of hours of fog , Days on which snow fell Days on which rain fell Days on which wind exceeded twenty-five miles per hour, but did not reach forty Days on which wind exceeded forty miles Hudson Strait. 9 102 4 8 5 1 This is a very favorable showing for Hudson Strait, and it is strengthened by the annexed table, affording a comparison between Station No. 1 at Cape Chudleigh and Belle Isle. This table covers the month of September : Number of days on which fog is recorded Approximate number of hours of fog Days on which snow fell Days on which rain fell , Days on which velocity of wind was between twenty-five and forty miles per hour Days on which velocity of wind was forty miles or over per hour Hudson Strait. 4 34 8 (5 So far as weather is concerned, therefore, Hudson Strait enjoys a decided advantage over Belle Isle Strait, and on that ground, at all events, presents no difficulties of such a character that they can not readily be overcome by experienced, careful navigators. Those portions of Lieutenant Gordon's report which deal with the resources and trade of the region he visited, interesting and important as they are, must be passed over for the present, while we hasten on to what he has to say concerning its natural history. Before doing so, however, it is worth noting that, although Hudson Bay belongs to Canada, its whale and walrus fisheries have been hitherto enjoyed by the Americans altogether, and the fur-trade has been entirely monopo- lized by the Hudson Bay Company,, so that the Dominion practically obtains no benefit from these vast possessions whatever. Lieutenant Gordon accordingly, very properly, presses upon the Government of Canada the necessity of their turning their attention to this unaccount- 232 THE POPULAR SCIENCE MONTHLY. ably neglected field for enterprise and investment, and especially of seeing that its treasures are not prematurely exhausted, but so pre- served as to be a permanent source of revenue and profit. We come now to Lieutenant Gordon's observations upon the nat- ural history of the country, and first of all as to its human inhabitants. These are very scanty, and, with the exception of a few white men at the traders' posts, are solely Eskimos. On the north side of the strait they are quite familiar with the ways of white men, and seem to be highly pleased at the prospect of increased intercourse with them. Occasionally one is met with who has mastered the English tongue, but not often. Many others understand well enough what is said to them in that language, although they can not be persuaded to speak it. They are particularly fond of any article of civilized clothing, and the head-man at North Bluff manifested no small pride at the posses- sion of a stand-up linen collar, which he displayed to the utmost ad- vantage. In character they are docile, amiable, and willing to work. When landing the stores and coal at North Bluff they worked all day along with the men, carrying heavy weights up over the rocks, and toiling away as cheerily and heartily as could be desired, asking no other remuneration than biscuits, of which commodity they are inor- dinately fond. These people have no farinaceous food of any kind, and, as a consequence, the children are not weaned until they reach the age of thi*ee or four years. The families are small, there rarely being more than two or three children, and, although early marriages are the rule, their numbers must be diminishing, because signs of their presence were met with everywhere, while the people themselves were found at only three places along the straits, and there are only some five or six families known to be between Cape Chudleigh and Nach- vak. Along the Labrador coast the Eskimos gather in small settle- ments around the Moravian mission-stations. Nain is considered the largest settlement, and its Eskimo population does not exceed two hundred souls. Those at the stations are all educated, being able to read and write in their own language, and, according to the mission- aries, are regular attendants at church, and very fond of music — two excellent and hopeful traits certainly. Practical prohibition prevails, thanks to the vigilance of the mis- sionaries, and the only liability to temptation that ever falls in the way of an Eskimo is when some unprincipled Newfoundland fisherman offers him a pull out of his flask. This, however, is a rare occurrence, and there is no record of any disturbance or trouble ever having been raised that would elsewhere demand the presence of a policeman for its quelling. The missions are so well managed as to be self-support- ing, the modus operandi being for the missionaries to supply the Es- kimos on loan with the very best traps, fishing-lines, and other gear, and then to purchase from them all their catch, whether it be seals, cod, salmon, furs, or anything else. A vessel which comes out from THE MEDITERRANEAN OF CANADA. 233 London every year transports the stock thus accumulated to London, where it is sold for the benefit of the mission, and in this way a con- siderable income is secured annually. In reference to the work thus carried on by the missionaries, Lieutenant Gordon pays them a well- deserved compliment by giving it as his opinion that their system of dealing with the natives, when honorably carried out, as it has been, and is on the Labrador coast, is the one which best meets the wants of the natives, and tends to the improvement of their condition. So much has been said by Arctic explorers about the incorrigible kleptomania of the natives they encountered, that we read with no less surprise than gratification this testimony as to the moral condition of the Eskimos at Hudson Strait : " One word may be said in regard to their honesty. Although scraps of iron and wood possess a value to them which we can hardly appreciate, they would take nothing with- out first asking permission ; not even a chip or broken nail was taken without their first coming to the officer who was on duty at the build- ing for permission to take it." In the matter of animals, the Hudson Bay region is quite as scanti- ly supplied as it is in human inhabitants, the list of terrestrial mam- malia comprising only four species, namely, the polar bear, the fox, the hare, and the reindeer. The skin of the polar bear is quite valu- able, a good one bringing twelve dollars with the agents of the Hud- son Bay Company. These animals, although reported by the Eskimos to be very savage, will not, as a rule, attack human beings unless first wounded or rendered desperate by hunger, under which circumstances any beast of prey becomes an undesirable neighbor. The Eskimos on the south side of the strait stated that, at certain times of the year, there were large numbers of these animals seen. Their meat is not unpalatable, but the liver is said to be poisonous. Of foxes there are three kinds found, to wit, the white, the blue, and the red. The white species would seem to be very numerous, judging from the number of skins seen with the natives. These skins, however, have no commer- cial value. The blue fox is properly of a steel-gray color. The skins are in good demand ; but the animals are not at all numerous. As to the red fox, its sole value consists in the fact that its presence indi- cates the "possibility of that most precious of all pelts — a black fox's — being somewhere in the vicinity. This species is met with on the south side of the strait, and black foxes are annually shot or trapped in the country south of Cape Chudleigh. The most important and beneficent of all the animals of the country, however, is the reindeer, which fur- nishes food and clothing, and much more, too, for its Eskimo master. The hare is common over the whole coast, and with game-birds of many kinds — geese, swans, duck, and ptarmigan — will no doubt furnish many a toothsome dish for the tables of the men at the various stations. Having thus traversed the whole ground sought to be covered by the expedition, Lieutenant Gordon brings his admirable report to a 234 THE POPULAR SCIENCE MONTHLY. close with some suggestions to the Government as to what should be done during the coming season. While much, no doubt, will be learned from the observations taken during this winter as to the formation and breaking up of the ice and generally in regard to its movements, and also of the other phenomena affecting navigation, it would be mani- festly impossible to state definitively from one year's observations what the average period of the navigability of the strait might be. In order to do this, the stations should be maintained for a second or even a third year. The question, therefore, as to whether the navigable season of the strait is sufficiently long to permit of an extensive commerce grow- ing up and being profitably maintained, remains still an open one, and must do so for perhaps a year or two more. Yet, in view of what has been already ascertained, it certainly seems as if the probabilities were all in favor of the Hudson Bay route being found practicable, and pressed into the world's service at no very distant day. The era of sailing-vessels is rapidly passing away. The freight- carriers between the continents will ere long be exclusively steamships, and to steamships properly adapted for the work the passage of Hud- son Strait has been clearly shown to be perfectly feasible and free from danger. The matter has resolved itself down to this single point : For how many months may a steamship navigate those waters ? And even if the answer, deduced from the observations taken at the stations now established, be that these months are too few to make the route pay, Lieutenant Gordon's expedition will not have been undertaken in vain, for it has thrown a flood of light upon a region hitherto com- paratively unknown, and has opened Canadian eyes to the fact that here, right in the heart of their own territory, they possess sources of wealth, both in the seas and on the land, requiring nothing but a little enterprise and capital to yield the most satisfactory returns. In the bay and adjacent waters the whale, porpoise, walrus, narwhal, seal, salmon, trout, and cod are ready at the summons of hook and harpoon to make substantial contribution to the national wealth. Upon the shore and throughout the islands minerals without number and forests without limit await the lumberman and the miner. THE WAYS OF MONKEYS. By Dr. ALFRED E. BREHM. SHEIK KEMAL EDIN DEMIRI, who died about a. d. 1405, and was the author of a voluminous treatise on the life of animals, relates the following story as a fact : " The inhabitants of a town called Olila, on the shore of the Red Sea, were in olden times meta- THE WAYS OF MONKEYS. 235 morphosed into monkeys, in punishment for their wickedness. They had broken the Sabbath by fishing. Some of their pious fellow-citi- zens endeavored in vain to convey them back into the path of virtue ; and, finally, when all admonitions proved useless, left the town. Re- turning to their homes three days later, they found, instead of their neighbors, baboons, which met them looking sorrowfully, and ex- pressing by signs and attitude that they recognized the friends whose advice they had scorned with so dreadful a result. In his anger, Allah had inflicted a terrible sentence upon them." The writer carefully insists on the circumstance that the culprits were Jews. The Prophet and his followers admit this metamorphosis by God's special intervention as a fact, and this fully explains the prominent part assigned to apes in all Arabic fables and tales. The early Egyp- tians believed religiously that some groups of monkeys were ex- perts in writing, and, by that fact alone, equal if not superior to mankind in general. A number of apes were consequently sheltered and fed in the temples, worshiped during life, and embalmed after death. Those privileged specimens of the four-handed tribe, when first introduced into the temple, were handed a slate and pencil by the chief -priest, and humbly requested to show their right to admission into the sacred asylum by writing. The gamboling and grinning candi- dates wrote, and nobody ever doubted that the figures traced by their agile hands fully deserved to be classed in the category of hieroglyphs. So highly were they held in respect and veneration, that the holy Sphinx was represented with their hair-dress, and, till to-day, men and women in the country of the Mahdi give their hair the same shape. But the Egyptians never admitted that the priests or Pharaohs were the de- scendants of monkeys, while, on the contrary, the Hindoos built houses and temples to shelter and worship apes, and venerated the princes of their country as the direct offspring of the holy animals. The Arabs regard the latter as " the descendants of the wicked, to whom noth- ing is sacred, nothing respectable, nothing too good or too bad ; who never feel friendly dispositions for other creatures of the Lord, and are damned by Allah, and carry the likeness of the devil and of man com- bined on their ill-shaped bodies." We, the sons of civilization, agree up to a certain point with the Arabs. We also — at least that portion of modern society who have not been given an education or an overtraining in physical science — decline to see in apes anything more than caricatures of ourselves, and repudiate with much aversion the inferences drawn from Dar- win's theory. On the other side, highly educated men all over the world have opened the discussion of the relationship between man and monkey, and speaking about the latter nowadays has become a dangerous task, in so far as there is but one alternative left — to offend the ancestry or the offspring ! For my own part, I feel no hesitation in approaching the question of relationship to examine its 236 THE POPULAR SCIENCE MONTHLY. value, and in trying to illustrate the life of that pretended cousin of ours. The apes have established their homes in every continent, Aus- tralia excepted. Warmth seems to he one of the principal conditions of their existence, as they are only found in the warmer regions. In America they are spread from 26° south to Mexico ; in Asia, from the Sunda Islands to the Japanese Sea. In Europe there exists hut one species of monkeys, and its members live all together in one troop on the rocks of the fort of Gibraltar, under the special care and protection of the garrison. That troop numbered in all twenty-three individuals when I visited Gibraltar in 1881. The principal thing the monkeys claim from a country, whose clime they are enjoying otherwise, is food, plenty of varied food ; and this fact fully explains the predilection they have always shown for places where pious superstition provides for their wants and makes their life comfortable. Among other mammifers the female element wields the scepter in family life, but in the realm of apes the male is invested with the sov- ereign power, not by general suffrage, but by the right of force. The oldest and strongest male of a troop proclaims himself chief and leader, after having vanquished all his competitors, viz., the rest of the senior males. The longest teeth and the strongest arms decide in the ques- tion of supremacy. All those who show some reluctance to submit are chastised till they come to political reason. To the strongest belongs the crown ; in his sharp teeth resides his wisdom. This ferocious tyrant understands his duty as a leader, and per- forms the same with dignity. His subordinates flatter and fondle him in every way ; the ladies of his harem rival in keeping his dress clean from annoying parasites. As a genuine pasha, he accepts this respect with a kind of languid acquiescence. In return, he watches carefully over his vassals, and shows a continual anxiety for their welfare and security. He orders and directs minute details in daily life, and sub- dues all opposition — for there exists a Left also in the monkey state — by striking and sharp bodily argumentation. As a general rule, the monk- eys go early to bed, rise late, and establish their night encampment on the summit of rocks, if possible'. The first thing they do in the morning is to warm themselves, for which purpose they climb to the tops of rocks and trees and turn slowly around in the sun till their hair, wetted by the nightly dew, is entirely dry. This preliminary operation is followed by a thorough cleansing of the skin, and, immediately after, by breakfast. Every eatable thing suits monkeys — fruits, onions, roots, seeds, nuts, leaves, insects, eggs, young birds, snails — and they enjoy generally a copious, free board. Their notions concerning property are very defective. " "We plant and the apes harvest," says the Arab of Eastern Soudan, with his natural apathy in the presence of facts and events that he can not prevent. Does not the monkey show in THE WAYS OF MONKEYS. 237 this a pronounced analogy with mankind who, since tLe existence of the world, though under severe penal legislation, find it so hard a task to observe the difference between mine and thine ? The hungry crowd of quadrumana infest fields and gardens : neither lock nor bolt, neither fence nor wall is an obstacle for those robbers, who steal and destroy everything in their way, whether it be eatable or not. It is not surprising, to any one who has witnessed such dep- redations, to see the farmers entertain a mortal hatred against these dark, grinning thieves ; and the Arabs range them in the category of evil spirits. When they are surprised in their mischievous work, they flee like cowards toward the nearest trees or rocks, the mothers carry- ing their children. Only when flight is impossible do they show fight, and attack men as well as the biggest beasts of prey, and even elephants, with that impetuous temerity which distinguishes the coward in de- spair. After a gestation of from seven to nine months, the female monkey gives birth to one young one, very seldom to twins. The new-born monkey is a little ugly creature, bare of hairs, with spindling limbs and a repulsive, senile face. But the mother is passionately fond of her monster, and caresses and nurses it with remarkable devotion. She does not leave it for a single moment, she presses it to her heart, rocks it to and fro, and takes the utmost care to keep it absolutely clean. In the first pei'iod of life the baby is apathetic and almost insensible, but begins gradually to play with urchins of its age. The mother is a patient observer of the first steps of her beloved, and watches care- fully that no harm may befall it. In the mean time, she trains it ; and the first virtue inculcated in the mind of the youngster is obedience, obedience in the strictest sense of the word. Men have ridiculed the maternal affection of the brute, and speak of "apish love." In our eyes the tenderness exhibited by the monkey may have a ridiculous side, but where is the man who could, without deep emotion, witness the anxiety of a mother-ape nursing her sick child ? I must confess that, to my eye, in such cases she is at least the equal of the human mother. If the young ape dies, the spectacle is a piteous one. The mother can not be separated from the dead body, refuses all food, and frequently perishes from grief. In such crises the ape proves cer- tainly his congeniality with the human race, and in his moral affec- tions could stand as an example to many men. The intellectual cultivation of which the monkeys are susceptible neither raises them so high above the average of mammifers, nor places them so far beneath the level of mankind, as some people contend. Further on, we find in no order of animals, as far as intellect is con- cerned, so wide a difference between the highest and the lowest indi- viduals as among the monkeys, while, in inverse proportion, the lowest- gifted human creature hardly differs from the apes whose intelli- gence is most developed. In many instances the mental and bodily 238 THE POPULAR SCIENCE MONTHLY. likeness to humanity is so pronounced that the observer feels quite uncomfortable in presence of the evidently small chasm existing be- tween man and beast. After this general characterization of the whole species, I may be allowed to trace in large outlines the families and some of their prin- cipal representatives. Science establishes two families, the monkeys of the Old World and the monkeys of the New World, and divides the lat- ter into two sub-families, viz., the claw or squirrel apes and the howl- ing monkeys, or scientifically, the Ouistitis and the Alouattes. The home of the ouistitis extends from Mexico to Brazil. The squirrel- apes are not yet perfect monkeys, though having the same number of identically shaped teeth as the monkeys of the Old World. Their limbs end in true paws, bearing narrow, compressed, and sharp-pointed nails on the four fingers ; the thumbs alone are provided with flat, large nails like human nails. They are the representatives of the transition from the unguiculated quadrupeds to the quadrumana, and rank, physically and intellectually, far below the genuine monkey with heraldic quarters. The easy, bold, and graceful movements of the latter in climbing, jumping, walking, and resting, are above their reach, and in the line of bodily abilities they hardly attain to their model, the squirrel. No one ever saw them walking in erect posture, and they always step on the full flat sole, contrary to the real monkeys, whose feet rest on the outer edge only. The cry of the squirrel-ape sounds like the whistle of mice or the pip of young birds, and its wit does not, by any means, reach the level of the genuine ape. A notorious coward, it shows all the coward's distinctive attributes — a plaintive voice, inability to submit to unavoidable facts and events, and the endeavor to swagger, even in the moment of flight. The first rank in the family of the apes of the New World belongs incontestably to the howling monkey. Its body is slender, its limbs are proportionately developed, its hands end in fjve fingers, and each finger shows flat, slightly convex nails. The fur is coarse, and the hair under the chin forms a kind of long, protruding beard. A distinctive feature is to be found in a kind of bony, sixfold drum or barrel formed by an inflation of the hyoid bone, which communicates with the larynx, and gives to the voice an enormous volume and frightful sound. Hence the name of howling monkeys. The long tail is naked, callous, and of great muscular strength at its extremity, and forms a convenient prehensile organ, which might be called a kind of fifth hand, or rather the principal hand of the animal. The alouattes are not poor climbers, but they never take bold jumps, and always keep their hold by the tail till their hands have grasped the next limb, aud this makes them slaves to the trees. They seldom venture upon the ground or on rocks. The howling monkeys herd in troops and follow slowly and awkwardly in the steps of their leader, whose slightest move- ments are imitated by every individual. There is no character in THE WAYS OF MONKEYS. 239 their voice nor in their general behavior : they act like automata and yell and howl like maniacs. In the morning, when all the rest of na- ture is rejoicing in the new-born daylight, the troop of howling monk- eys will descend gravely from the leafy tree where they have passed the night, closely gather in a huddled crowd, and, having secured some breakfast, will proceed to indulge in a kind of social entertain- ment which is as exempt from frivolity and impropriety as it well can be, but which well reflects the character of the participants. The company make choice of some leafless tree, which they climb with great dignity. Each member takes his place as he pleases, but one large bough is reserved for the exclusive use of the leader, who paces it to and fro, solemnly raising his tail, and begins to utter low sounds, similar to the grunt of a young hog. The prelude grows insensibly louder, the time is quickened, after a few moments the pauses are omitted, and the wretched tune, sinister at first, becomes an unin- terrupted, dreadful yelling. Now the crew are thrown into raptures, and all join in one deafening cry and howl in concert. The powerful roar of the jaguar, the terrific growling of the panther, the wild shouting of a crowd of beastly, drunken rustics, lamentations, groans, seem to be combined in this chorus. And, curiously, the artists have no idea of expressing any special feeling. Such entertainments some- times last several hours. Those long-tailed howlers are tiresome creatures, and I must confess that, in the matter of apes, the Old World takes the lead. Here, also, we find two sub-families — the Cynopithecini (dog-apes) and the Anthropomorpha (man-shaped apes). The former have perfectly developed teeth, like the quadrupeds, and a tail ; the Anthropomorpha, on the contrary, have no tail, and their set of teeth resembles that of men, with the exception of the canine teeth, which are stronger and intermediate between those of beast and man. The Cynopithecini present almost all the features in character which distinguish monkeys in general. The leadership is intrusted to the strongest male ; he assigns to each member of the troop his duties, and watches for the general welfare. Their well-shaped hands give to these monkeys advantages which other animals do not enjoy, but still it is a question whether the dog could not in justice be placed on the same level with them as regards intelligence and sagacity. Apes and dogs show discernment and exercise restraint on their manner of living ; both are aware that every disorderly act on their side is fol- lowed by punishment, but the apes believe themselves far above the dogs. Excessively susceptible to reproaches, they want to be praised and fondled, while they themselves tease and insult other animals at every opportunity. They are docile, they eat with knife and fork, drink from the glass, dress, ride on horseback, submit to military drill- ing, wait on their masters, but only when, where, and as long as they are pleased, and never with the same care and conscientiousness that characterize a well-trained dog. There is no troop in the world so hard 240 THE POPULAR SCIENCE MONTHLY. to manage as a troop of these monkeys, which peculiarity hrings them near the hopeful youth of modern age. Another proof of their supe- rior intellect may be found in the fact that they avail themselves of the means afforded by others to make their life as comfortable as pos- sible. I had often seen and closely observed individual baboons in cap- tivity, but had never had a chance to meet those interesting animals living the life of liberty in organized troops. That pleasure was in store for me one morning, in the year 1862. I was traveling in Bogos- land at the time. On the morning in question I found myself sepa- rated for a while from my companions, and had just sat down to take a short rest when I heard a kind of strange barking, coming from a steep cluster of rocks in the vicinity. Some minutes before my atten- tion had been aroused by a number of curiously shaped forms on the summit of the rocks, but I came to the conclusion that they were large blocks of stone. The barking disabused me, inasmuch as the forms, true and genuine baboons, were now starting up. Considering the shouting of the animals as a personal provocation, I hurried up the hill and fired a shot at the troop, which at once took to their heels and were soon out of sight. About half an hour later, after I had joined my friends, we saw the same troop in file on a narrow bridge running at considerable height along a rocky wall. Another gunshot made them disappear once more, but a short distance farther, where the valley turned at a sharp angle, we met them just at the moment when they were crossing to reach the opposite hills. Our hounds, though trained to hunt hyenas, hesitated in bewilderment, but soon gave tongue and made an impetuous rush at the monkeys. At once the old males rallied and faced the dogs, forming a wide semicircle, roaring, grinning, and furiously beating the ground with their hands. Their threatening attitude and spiteful glances frightened the hounds, which recoiled in amazement. The monkeys took advantage of this moment- ary failure of our animals and retreated in haste. When the latter were rallied and started for a fresh attack, there were only a few more in the valley, and the last of the stragglers was a pug of about six months, which retreated in agonizing terror to the top of a large block of stone where the hounds set it. " That pug will be ours," I shouted, but was thoroughly mistaken. One of the senior males, a strong, pow- erful individual, started from the other side of the valley, advanced quietly toward the block, pride and mischief shining in his eyes, marched straight to the hounds, which trembled under his vicious glances and threatening gesticulations, climbed the stone, fondled the young one, put it on his back and calmly returned, while we were standing there all startled. Similar acts of self-exposure of a male are only found among monkeys, while among all the other animals, even the lions, it is always the female which risks life to save her cub. Some time afterward I crossed the same valley in company with THE WAYS OF MONKEYS. 241 Duke Ernst, of Coburg-Gotha, and near the same place we met the troop moving half-way up on the rocky slope of the hill. On the duke's motion, we resolved to offer them fight. Seven men, armed with patent rifles, opened the attack. At the first volley the females took to flight with the young ones, while the males not only did not flee, but advanced, and in less than no time a formidable hail of stones whistled around our heads. Some of the stones thrown were as large as a man's head. It was full time for us to withdraw, and so we did. The monkeys remained the masters of the battle-field. On my second voyage to Eastern Soudan we stopped in Khartoum during the rainy season. I suffered much, even more than I am suffering here in New York, from fever and chills. In the long, tedi- ous hours of leisure we made a collection of monkeys, and those ani- mals cheered me up many a time in my physical and mental troubles. We played with them, and at the same time undertook their training, and that in a fashionable manner. So we gave them riding-lessons. An old, fat, lazy donkey had the honor to serve as horse, and, although the apes showed disgust and fear at first, one single lesson was sufficient to initiate them into the secrets of the noble sport, and in a few days they were, in their way, masters in the art. They would mount the donkey three, four, and five at a time, the first one em- bracing fondly the neck of the trotter with the fore-hands and cramp- ing his hind-hands convulsively in the pelt of the animal's abdomen ; the next one taking hold of his comrade, and securing his equilibrium in the same way by means of the hind-hands ; and so on in a file. A funnier sight than this, four or five grinning apes closely nestled to the donkey's back, can hardly be imagined. The gray-haired trotter sometimes had to suffer from the mischievous riders, and did not con- ceal his feelings, to the great amusement of his tormentors. Besides playing, the monkeys were instructed in many little arts and tricks, and on that occasion I learned to appreciate them as smart and most sagacious creatures. But passion makes them blind — unlike men, as it is said by the monkey-haters — as if men always kept quiet, composed, even-minded, and sober ! As well as the apes in general, our baboons were passion- ately fond of strong liquors, and had a peculiar propensity for merisa, a kind of beer made of the grains of durrah by the inhabitants of the Soudan. Brandy was not to their taste, but, unfortunately, they made an exception one day. After having swallowed copious quantities of merisa, each one of the troop was offered a big glass of date -brandy, which he drank. As a consequence they became completely intoxicated, insolent, passionate, bestial, and grinned and gamboled in a fearful manner ; in one word, they offered the hideous caricature of drunken men. The next day thirteen of the drunk- ards were suffering from the consequences of the spree, and looked sick unto death. All food gave them nausea ; they turned away with VOL. XXTII. — 16 242 THE POPULAR SCIENCE MONTHLY. disgust from merisa and even from wine, a favorite beverage in ordi- nary time ; the only things they accepted were lemons, of which each one ate an average of twenty pieces. In this wretched state they comported themselves like men, and would, doubtless, have enjoyed a sour herring if it had been possible to secure this antidote in the country of the Mahdi. In the evening they felt better, and were all right the next morning. I hoped this hard lesson would teach my pupils the advantages of abstinence, but, alas ! I was mistaken once more in my life. They drank and reveled all the same, and from that day drank brandy with predilection. More than that, they claimed their rum every day as a privilege. I took one of these baboons — it was a female — along to my home in Germany, because she had always proved to be of extraordinary sagacity, and actually exhibited a far greater intelligence than the average of the countrywomen of Thuringia, where I was living. Apes in general like other creatures, provided they submit to their caressing and fondling. My baboon at first concentrated her tenderness upon the children of the village, but, to her great sorrow, found no recipro- city. Then she turned to cats and dogs, and teased and tormented them in every way. A bright pussy, which the most of the time she carried in her arms, was tired one day of her company and attempted to escape. The ape strongly objected, and the kitten, in its strug- gles, scratched her in the shoulder. Gravely the baboon seized one of the paws of her pet, examined it carefully, and finding, probably, the sharp claws a dangerous superfluity in so small a being, bit them all off, one by one. We sometimes tried a practical joke on her by put- ting a little powder near the place where she was secured during part of the day, and flashing it by means of burning spunk. When the powder flashed, she screamed and jumped back as far as her chain per- mitted it. But she had very early found out the connection of things ; the next time we threw the burning spunk near the powder, she rushed forward, extinguished it, and quietly ate the explosive, which she prob- ably relished on account of its saltpetrous taste. The aptitude of the Cynopithecini to distinguish between cause and effect is really remarkable. They are aware when they have done wrong, and expect punishment. An old crowned guenon, also called Chinese bonnet, living in captivity, once assaulted its attendant, lacer- ated his arm, and cut an artery. The animal being an old offender, the master ordered it to be shot. When the man charged with carry- ing out the order approached the cage of the ape, the latter, appre- hending his fate, retreated to the adjoining shanty serving as bedroom, which communicated with the cage by a door. Neither flatteries nor tempting titbits could move him to come out from there. The man then had dinner brought and placed in the front cage as usual, and walked off. As soon as he was out of sight, the monkey cautiously crawled out, took part of the food, and jumped back to his hiding- THE WAYS OF MONKEYS. 243 place. He went a second time, but found his retreat cut off, the door between the cage and the shanty having been shut. Seeing at the same moment the attendant armed with the dreadful gun reappear, the monkey understood at once that he was lost, jumped furiously at the closed door, tried to escape through every corner, and, finding that flight was impossible, lay down trembling, and awaited the deadly bullet. The ape holds himself far above the other animals, and endeavors to make them understand it. My baboon showed her superior stand- ing by tormenting every other animal in the house without any reason or the slightest provocation. I had an old dog whose temper had been spoiled by age, and which lived in open war with every creature in the house. My baboon picked it out as an object for her tricks. Wben the dog was taking its siesta, the ape would crawl cautiously near, seize the animal by the tail, and, jumping back, give it an awful jerk. The dog, roused from slumber, flew into a violent passion, and went howl- ing and barking for the ape, who quietly watched him, and aggravated his excitement by patting the floor with her hands. As soon as the dog was near enough to reach her, she made a jump upon his back, and again squeezed his tail. These successive insults made the dog nearly frantic ; he foamed and howled, but, the more excited he grew, the worse the monkey tormented him. Finally, the old hypochon- driac, seeing the uselessness of trying to chastise the foe of his rest, marched off with his tail between his legs whenever the monkey showed her face. The sagacity and docility of the Cynopithecini, wonderful as they are, can not be compared with the intelligence of the Anthropomorpha, especially the chimpanzee, the gorilla, the orang-outang, and others. I have closely observed several individuals of the family, allowed them to play with my children, and cared for their training and education, and have drawn astonishing results from my studies. These monkeys are creatures which one treats involuntarily like men, or at least like chil- dren. The orang-outangs are melancholic and not very sympathetic with men ; the variety of the pongos, to which the chimpanzee belongs, is jovial and by far the most intelligent. Their voice is pure and plain, and, while it can not be denied that the voice of the gibbons sounds more melodious and constitutes a veritable song, that of the chimpan- zee is a formal language. All the sounds are fully accentuated, and the observer soon understands the meaning of the different modula- tions, while children, playing with the animal, catch at once the sense of its utterances. It is really impossible to treat the chimpanzee like an animal ; his character and general behavior show so much of humanity that men are induced to commune with him in the same way as with their equals. In captivity he is perfectly conscious of his position, and sub- ordinates himself willingly to the superior mental gifts and capacities 244 THE POPULAR SCIENCE MONTHLY. of mankind, but holds himself better and higher than other animals, especially than other monkeys. Paying in every instance high regard to men, he likes children if they do not tease and molest him. Sportive and humorous, he indulges in joking with men and animals. He is not only inquisitive but eager to acquire knowledge, examines carefully things strange to him, and falls into ecstasy when he has found out their purpose and learned to use them in the right way. While able to under- stand men and things, he is, nevertheless, modest and kindly, seldom willful, and never stubborn, although he claims what is in right due to him. Of variable temper, he is now good-humored and jolly, now sad and morose, and gives vent to his feelings as men do, but sometimes in a more passionate way. I was once the owner of a highly educated chimpanzee. He knew all the friends of the house, all our acquaintances, and distinguished them readily from strangers. Every one treating him kindly he looked upon as a personal friend. He never felt more comfortable than when he was admitted to the family circle and allowed to move free- ly around, and open and shut doors, while his joy was boundless when he was assigned a place at the common table, and the guests admired his natural wit and practical jokes. He expressed his satisfaction and thanks to them by drumming furiously on the table. In his numerous moments of leisure his favorite occupation consisted in investigating carefully every object in his reach : he lowered the door of the stove for the purpose of watching the fire, opened drawers, rummaged boxes and trunks and played with their contents, provided the latter did not look suspicious to him. How easily suspicion was aroused in his mind might be illustrated by the fact that, as long as he lived, he shrank with terror from every common rubber-ball. Obedience to my orders and attachment to my person, and to everybody caring for him, were among his cardinal virtues, and he bored me with his persistent wishes to accompany me. He knew perfectly his time for retiring, and was happy when some one of us carried him to the bedroom like a baby. As soon as the light was put out he would jump into the bed and cover himself, because he was afraid of the darkness. His favor- ite meal was supper with tea, which he was very fond of, provided it was largely sweetened and mixed with rum. He sipped it from the cup, and ate the dipped bread-slices with a spoon, having been taught not to use the fingers in eating ; he poured his wine from the bottle and drank it from the glass. A man could hardly behave himself more gentlemanlike at table than did that monkey. He was especially engaging in his association with my children, always gentle, obliging, and tender, and they liked him as a good fellow and pretty playmate. When he was first introduced to my little girl, who was then six months old, he seemed perplexed, and observed her with astonishment, as if speculating whether that little bit of a creature was really a human being. At last his mind was THE WAYS OF MONKEYS. 245 made up ; he touched her cheek with one finger and then offered her his hand in friendship. My chimpanzee conversed very little with other animals ; like the apes in general, he was afraid of the big ones and despised the smaller ones. He was always around us, and we, on our side, did not make any difference between him and a man. The animal fell ill of mumps, followed by pneumonia. I had seen many sick chimpanzees, but never one of them behaved as he did. I engaged two competent physicians to take charge of him. He knew them from the first day, allowed them to feel his pulse, showed his tongue, and directed the hand of the attendant doctor to the pain- ful swelling, which had to be cut open afterward, there being danger of suffocation. The doctors would not use chloroform, out of regard to the affection of the lungs ; but, fearing the chimpanzee would not keep quiet during the operation, engaged four strong men to hold him. The sick animal did not submit to that rough treatment, but excitedly pushed the men aside, and then, without any compulsion whatever, but in compliance with the fondling words of his nurse, in whose lap he was sitting, offered his throat. The operation was performed, the ape never flinching or complaining. He felt afterward much relieved, and ex- pressed his gratitude by pressing fervently the hands of the physicians and kissing his nurse. But his life was not spared ; he died from pneu- monia. Meekly and patiently he bore his long agony and died more like a man than an animal. The doctor told me that never in his life, at any death-bed, had he felt an emotion similar to that which seized him at the humble couch of the poor monkey. In Berlin, many beautiful eyes shed tears when the news of the sad end of my widely known and generally petted chimpanzee was spread. Was the ancestor of the human race a monkey ? That is the vexed question which still raises so much dust. There is no doubt that man is not more and not less than the chief creature in the animal kingdom, and that the monkeys are his immedi- ate neighbors ; but I can not see why this fact should logically involve the assumption that our great-great-uncles were gamboling in paradise in the shape of apes. The doctrine of gradual evolution may seem trust- worthy in the highest degree and beautiful from the scientific stand- point, but it is based upon a simple hypothesis, and a hypothesis is not a proof ; and here I wish not to be misunderstood. Even if the physi- cal and intellectual development and perfection of humanity through- out the succession of thousands of centuries is a fact, there is no authority for the inference that, eo ipso, a monkey-nest was the cradle of mankind. Darwin's treatise on the variation of species gave rise to the ardent controversy of our days. Darwin used the wrong word. It is not " species " he ought to have said, but " varieties " ; for species never interbreed with each other. Man and monkey, though belonging to the same group, represent two distinct species. There is, consequently, 246 THE POPULAR SCIENCE MONTHLY. a simple and irrefragable natural law refuting peremptorily the thesis of the enthusiastic propugnators of the pedigree rooting somewhere amid a grinning tribe gamboling in the wild forests of Asia or Africa. The criterion that the human race has large, round hands and blunt canine teeth would be sufficient of itself to establish the truth that no monkey-blood is pulsating in our veins ; but there are more distinctive features. Men have strong, well-shaped legs, walk constantly in an erect posture, and enjoy the faculty of speech. The monkeys rank near humanity in the general organization of the world ; they show in many instances much likeness with mankind, physically as well as intellectually. But a further concession would be a denial of positive natural laws. Nay ! old Adam was not a monk- ey, not a baboon, not even a chimpanzee ! MOTHS AND MOTH-CATCHEKS. By AUGUSTUS E. GEOTE, A. M. ONE day, in the British Museum, while waiting a moment in a room where entomological specimens were exhibited, I saw two workmen bending over a case containing butterflies and moths. " There is the Camberwell Beauty," said one, pomting out a par- ticular example to his companion. "Ay ! " was the ejaculatory response, and the tone of that "Ay !" I am not likely to forget. It took me at once to the speaker's proba- bly humble home, stored with treasured specimens in their boxes, pinned down low, labeled and arranged. How many hours of stormy evenings had not been pleasurably spent in sorting and debating, in setting and classifying, these downy bits of Nature's finery ! From how much worse employment may not these "little beauties" have saved their owner ! There is no doubt that in England, as well as in France and Ger- many, the collecting of moths is a very general recreation as compared with the United States. That it is harmless is a negative praise ; that a pursuit of its objects is healthful, and takes the man who works in the city out into the fresh country air, is a positive recommendation. But the labor is also instructive. Things have now changed very much since the days of Malpighi, and biology is a respected and neces- sary study. And throughout the world of animated beings it may be safely said that the growth and changes of life can nowhere be so easily and pleasantly observed as in the rearing of butterflies and moths from the egg. As to butterflies, it may be asserted that they are less interesting than their cousins the moths, who constitute the MOTHS AND MOTH-CATCHERS. 247 elder branch of the great natural group of scaly-winged insects, or Lepidoptera, to which both belong. The butterflies are less numerous in species, or kinds, and more uniform in habit and appearance. These gaudy and papery- winged day-flies have their own attractions and pre- sent their own scientific problems, but in number, diversity, soft and delicate colors, and patterns and unexpected modes of life, they can not hold a candle, to speak both figuratively and appositely, to the foolish but lovely moths. First, let us assure ourselves that by moths we do not mean clothes- moths. These terrors to the housekeeper are only of two or three kinds, and of small size, belonging to the genera Tinea and Tineola; while there are over seven thousand species of North American moths already in our catalogues, from the large and gorgeous "Regal Moth" ( Citheronia regalis) to the "Tiny Gem" (Lithariapteryx) , of all shades of color from gray to pink, from black to yellow, all innocent of carpet- or clothes-eating in their young larval days. To some general state- ments as to these, the methods of hunting and preserving them, and those who carry on the fascinating pursuit, I claim the reader's indul- gence for a few pages of what I shall try to make easy and instructive reading. It is, perhaps, unnecessary to state that moths, like plants, bear, each kind, a particular double Latin or Latinized title, as Actias lima, the " American Moon-Moth," or " Queen of the Night." The first name is that of the genus, the second of the species. The genus is founded on certain particular points of structure, and usually em- braces a number of kinds or species which share in these particular structural features. While the genus Actias, for instance, is known by its thinly scaled, pale-green wings, the hind pair furnished with twisted " tails," our species lima differs from a number of Asiatic and African species by certain marks and peculiarities of pattern and size. These Latin names are a source of some difficulty to lay readers and to many amateurs. Some people prefer English names by which to designate their specimens, but our species have not been known for years, as have the European moths ; consequently very few have re- ceived vernacular names. The " cotton- worm " (Aletia argillacea), and the " army- worm " (Heliophila unipiincta), are, indeed, two species of moths well known for their ravages in the larval state, and which are consequently provided with vernacular names by which they are distinguished. But we have no English names for the great ma- jority of species, which are really different in kind from their trans- atlantic brethren. The introduction of common names for our moths is evidently a matter not to be forced, but to be left to itself. The rule of priority, which Linnaeus appointed to govern the Latin names, can not obtain here. Some of our butterflies have received several English names, as the common "milk- weed butterfly." Some of the names for moths in 248 THE POPULAR SCIENCE MONTHLY. use in England are very pretty, such as the "Arches" and " Wains- cots " ; others are peculiar and less attractive, as the " Pugs " and "Lackies." English names for our moths will, it is to be hoped, gradually appear in our literature and come into general use. The vernacular names proposed in economic works, such as the reports of State entomologists, are often very ugly, and have nothing to recom- mend tbem. They are simple translations from the Latin in many cases, and are then quite often ridiculous. Dubiosa is translated doubtful; fraterna, fraternal, and so on ; it is clear that the Latin names are much better than these. But see what lovely names they have in England for their moths : the " Kentish Glory," the " Peach- Blossom," the " Buff Arches," the " Common Wainscot." About the vernacular names for our moths must come the cooling touch of time ; they can not be struck out in the heat which accompanies the coining of a Latin name for a new species. Around their cradle some tutelary divinity must hover ; some old tale, like an ancient crone, must be its nurse ; out of some melody, dedicate to fields and flowers, must the words be taken which are to serve as the title for the new-comer. Af- fection for the object, quite distinct from the passion of the scientist, must have its part in the English name, which should also be apposite and express the appearance or habit of the moth. One of the names proposed for a North American species, Ommatostola Lintneri, appears to fill these conditions — viz., the "Dune Wainscot." It is a reed- colored moth, found on the sandy ridges (dunes) near the Long Island beaches. Again, another species, vividly colored, black, pink, and yel- low, is called the " Spanish moth," as it bears the Spanish colors. Its scientific name is Euthisanotia timais. It breeds in Florida, and comes up our Atlantic coast-line in summer, being often beaten into the lighthouses with the birds, during wind-storms, or simply attracted by their light. Our species of moths east of the Mississippi are pretty well known, and all but the very small ones, the Tineidm or leaf -miners, are described in different publications. What a change during the twen- ty-five years which have just passed, and which span my own career as a catcher of moths ! When, a boy of fifteen, I tried to find out the names of some of our moths, I had great difficulty in ascertaining that there was such a science as entomology at all ! At that time, even in Agassiz's museum, at Cambridge, there were not fifty kinds labeled which had been described and named in this country. Now we have about seven thousand names of known species in our catalogues, and from one to two hundred are being added to the list every year. Our new discoveries come chiefly from the West, where wonderfully beautiful species are " turned up." Arizona and New Mexico, as well as Colorado, seem to be perfect paradises for rare and lovely moths. The reader will have seen that there are two kinds of names, the scientific and the common. Nothing, it seems to me, that will promote MOTHS AND MOTH-CATCHERS. 249 popular interest in the study should be neglected ; therefore I hope that pretty English names for our moths will appear and lighten the studies of many who find Latin difficult and ugly. It must be remem- bered, however, that when we wish to designate a certain kind of moth with precision, we are obliged to fall back upon the Latin name, and that there is a good deal of prejudice against common names by scien- tists, whose opinions are worthy of respect, but whose foible it is to be very exact and precise in their statements about a moth, or any object upon which they have special information, but who are otherwise as fallible as the rest of us when it comes to matters of conduct and art. The old saying in natural history, that everything comes from an egg, holds good for moths. Nevertheless, modern science has wrought wonderful changes in our ideas on this subject since the days of Ray and Willoughby. The young are now considered as part and parcel of the old — a continuation, to some extent, of the bodies of their parents, whether we consider a moth or a man. The affinity between the seed of a plant and the egg of an animal is indeed illusory, but in some of the lower animals there is a process of reproduction allied to budding in plants. Years ago the poet Chamisso discovered the fact that the young of a lowly organized marine animal called Salpa did not resemble their parents. We know now that in some cases several generations in- tervene before the final form of the species is assumed. When we read of the discoveries in biology of Goethe and Chamisso, we see that there is some justice in the observation that it is the poet who under- stands Nature best. Perhaps we should rather conclude that the im- agination is a quality which the naturalist can by no means dispense with. Goethe's theory of the true structure of the vertebrate skull is now accepted ; Chamisso died before Steenstrup, in 1824, vindicated at least the general truth of his particular observations. A curious story is told of the first discoverer of the true nature of the coral- makers. The French Academy of Sciences would not print his essay on the subject, and persisted in the old belief that the coral was a plant. To return to our moth-eggs. While certain flies reproduce by a sort of budding in the larval state, our moths, so far as known, all come from eggs laid by the female moth on leaves, flowers, or the branches and trunks of trees. Some are inserted in crevices of the wood itself, and the little caterpillars, when they hatch, bore into the heart of the tree upon which they feed. The " peach-borer " (JEgeria exitiosa) and the " plum-borer " (JEgeria pietipes), Bailey's " goat-moth " ( Cos- sus centerensis) are examples of certain kinds of wood-eating cater- pillars. The little moth-eggs, usually attached singly, sometimes in belts and clusters, vary in the length of time which elapses before they hatch after they are laid. It is difficult to assert that there is any rule in this respect, and it is certainly hard to tell when they are "addled." When they are " bad" and fail to give the little worm, it is often be- 250 THE POPULAR SCIENCE MONTHLY. cause they are " stung " by minute four- winged flies, parasites upon these tiny objects. One of the most curious things about the laying of moth-eggs is the botanical knowledge of the mother-moth. In the dark she knows the particular trees upon which her brood flourish, out of a whole for- est. The proverb about one man's meat being another man's poison holds good when applied to the caterpillars of moths. They will starve, as a rule, before eating, or die upon eating, the wrong kind of leaves. The little eggs, sown here and there by the mother-moth in her nocturnal flights, are often very pretty to look at through the microscope, being adorned with delicate traceries. Some kinds are nearly smooth, as those of the Cecropia, which are quite easily found on lilac and other leaves, gummed on, with a little brown spot above, over the micro- pyle, through which the curled-up caterpillar within, a little black, thorny creature, escapes. Some caterpillars eat the empty egg-shell for their first meal, but the practice is far from general. Some which I par- ticularly noticed, those of the " chestnut-stripe " or honeysuckle-leaves, only nibble at the empty egg-shell, and, I thought, were attracted by some of the softer parts which might remain. The caterpillars of this moth (Homohadena badistriga) afterward make a rather stout cocoon ; I have reared them from eggs found in the back-yard of a house in the heart of New York city. So far do our country friends penetrate. The bodies of caterpillars and moths are made up of segments, or rings, hardened by a substance called chitine, so that it has been said that insects really follow out Sydney Smith's suggestion, given under exceptional circumstances, and " sit in their bones " the whole time. They strike against the outside world with the knobby parts of their anatomy. A child once described a caterpillar as a " jointed tube, filled with soft stuff." I don't know how she found out about the " soft stuff," but the insides are soft, and, when carefully exam- ined, show the respiratory canals, opening by little narrow slits in the sides of the segments (for insects do not breathe by the mouth), the nervous and the muscular systems, networks of little whitish threads, as also the central digestive apparatus, which takes up the most room, as our caterpillar is principally a feeding animal. The stiffness of the rings of insects is obviated by their being connected by a highly flexi- ble membrane. The caterpillar increases in size by changing its skin. The old covering becomes too small to hold the food which is retained and transformed by the chemistry of the body into caterpillar-flesh. It splits behind the head, and, with more or less trouble, the cater- pillar frees itself from it, stepping out, and leaving its old skin, a thin and almost colorless pellicle, to be blown by the summer winds into Nature's rag-bags which the spiders mostly carry about. Caterpillars are of all colors, and, within certain limits, of all sizes, variations of the " jointed tube, with soft insides." They are plain and smooth, or ornamented with tufts of hair, or fleshy, colored humps ; MOTHS AND MOTH-CATCHERS. 251 when young, the head and tail are somewhat swollen, and in this state one kind has been described as looking like " little animated dumb- bells." When they attain their full size, they prepare to pass into the chrysalis state, and here their methods are equally diverse. A few hang themselves up by threads, like butterflies ; others penetrate the ground, and, without any web, change into a naked, brown-colored pupa, which reposes in a sort of cell, made merely by the movement of the caterpillar pressing back the earth. This is the burial of Psyche. From it a host of oratorical and poetical figures are taken. It affords, in one way, even religious consolation. The human body, buried in the mold, gives to eternity and heaven the soaring soul, as the chrysa- lis, from its earthy cell, discloses the moth which beats the ether with unquiet wing. Again, many kinds of caterpillars spin thick cocoons, as the "American silk-worm" (Telea polyphemus), the "cecropia moth" {Platysamia cecropia), and the " sassafras emperor " ( Callosamia Pro- methea). Many have been the efforts to utilize the silk thus made by our native moths, and interesting experiments are detailed with that spun by the American silk-worm, as published by Mr. Trouvelot. The silk of all these species can be no doubt used, because the Chinese and Japanese silk-worms belong to the same or nearly related genera. But none of them equal the original Indian or European silk-worm, the Bombyx jnori, cultivated chiefly in the south of Europe, and which yields the silk of commerce. After several unsuccessful at- tempts, of late years, the rearing of the cocoons has been profitably undertaken in the United States, probably through the establishment of silk-mills and the protective tariff which stimulates the silk in- dustry. Everywhere in the country one may find the chrysalides of moths. Under stones, under moss, and beneath the loose bark of stumps, spun fast to branches and wrapped in the dead leaves of autumn, at the foot of the trees which fed the caterpillars, they may be found in all sorts of hiding-places. The duration of the apparently torpid chrysa- lis-life is different with the season and the species. From a few weeks to sometimes two years, the still nascent insects lie imprisoned. But at length the hour for escape arrives. The brown shell of the chrysa- lis splits, and the moth, struggling out of all its envelopes, crawls to some near foothold, where it may shake out and expand its feathery wings in safety. And then, when night comes, and the breeze, it gives itself to the darkness, braving all dangers, to deposit its eggs in safety and perpetuate its species, its main object accomplished often at the sacrifice of its own brief life. While the moths are inseparably connected with the butterflies, we shall know them by their antennae not being knobbed at the tip, their more downy wings and body, their generally softer colors, and their usual sleepy habit in daytime, when they fold their wings and seek dark places for repose. 252 THE POPULAR SCIENCE MONTHLY. Except a few small groups, most of which I can not admit as form- ing distinct families, our North American moths may be divided into ten groups, to each of which the term "family" is applied, just as we have the same term given to certain similar groups of other animals, such as the birds or fishes. These ten families are : 1. The Sphingi- dce, or " hawk-moths," of which we have 91 species in our territory ; 2. The ^Egeriadce, or " clear-wings," of which there are catalogued about 120 sorts ; 3. The Zygceniclce, or " clear - spots," comprising over 60 kinds ; 4. The Bombycidm, or " spinners," of which there are more than 400 species ; 5. The Noctuidce, or " owlet - moths," with nearly 1,600 different kinds ; 6. The Geometridce, or "spanners," with 500 species ; 7. The Pyralidce, or " snout-moths " ; and 8. The Tortricidce, or " leaf -rollers," with over 400 kinds of each ; 9. The Tlneidce, or " leaf -miners " ; and 10. The Pterophoridce, or " feather- moths," the former a large family of minute and often brilliantly col- ored species, the latter a smaller one containing curious slender moths, having the wings split into feathery fingers or rays. These last two groups are very incompletely known. [To be continued.] -■+*+-- CONCERNING KEROSENE. Br Professor S. F. TECKHAM. A MODERN French writer has said : " In the domain of the use- ful arts each age reveals characteristic tendencies. In the last century, mankind had need to clothe itself cheaply. . . . The nine- teenth century has wished for light." To the development of the pe- troleum industry the gratification of this wish is mainly due ; yet, while the products of petroleum are used in nine tenths of all the dwellings of the land, but few of those who occupy them realize that 60,000 barrels of crude oil flow from the earth every day, that more than 30,000,000 barrels are now stored above-ground in huge iron tanks, and that 15,000 barrels are required to supply each day's de- mand in the United States alone. Of this vast quantity, by far the largest proportion is consumed as illuminating oil, or kerosene, for the production of which a stream of oil is constantly flowing through six- inch pipes from the oil-region of Western Pennsylvania to Baltimore, Philadelphia, and Jersey City. In each of these cities establishments, constructed for the purpose, convert the crude oil into various products, principally illuminating oil, for the home market and an export trade of vast proportions. In these refineries the oil is first allowed to settle in large tanks, in which a small percentage of water and sediment accumulates. From these tanks the oil is pumped into stills, holding CONCERNING KEROSENE. 253 about 1,200 barrels each, beneath which fires may be kindled, and urged by a strong draught until a red-heat is attained. Petroleum consists of a great many different fluids, which range in volatility from the boiling-point of ether to nearly a red-heat. Such being the case, as soon as the oil is heated at all, the most volatile products begin to come over, at first colorless as water, but very gradually assuming a yellow tinge until the most dense distillate com- ing over at the last is quite dark brown in color, so that, if all the dis- tillate were allowed to run into a tank together, it would not look very differently from the original petroleum. In the ordinary process of refining petroleum, the distillate is divided into three portions. The first is the lightest, colorless portion, nearly as volatile as ether, and is called crude naphtha, or "benzine." Like the crude petroleum, this crude naphtha may be distilled and divided into gasolene, A, B, and C naphtha, which are used in gas-machines, for mixing paints, and other similar purposes, sometimes also for burning in lamps and stoves. The middle portion of the distillate, which is neither very light nor very heavy, and having but little color, is the crude illuminating-oil, or kerosene. As it runs from the still it has a very offensive odor, due to the decomposition of certain portions of the petroleum at the high temperature reached in the still. To remove the offensive compounds, the oil is first agitated with about five per cent of strong oil of vitriol. This combines with the offensive oils, forming a black, tarry residue that falls to the bottom of the tank as soon as the oil is brought to rest. This mixture of acid and oil is called " sludge," and is used in large quantities in the manufacture of commercial fertilizers. After the acid is drawn off and the oil washed with water, it is again washed with a strong solution of caustic soda, which removes the excess of sulphuric acid, and also some peculiar acid compounds that exist in the oil. The oil, after another washing with water, is nearly colorless, with the peculiar balsamic odor of kerosene, and possesses the slight opalescence peculiar to these oils. As usually prepared, they belong to the class known as " high-test " kerosenes, and consist almost en- tirely of oils that exist in the petroleum already formed, being merely separated from the lightest and heaviest portions. Such oils are called the eclucts of the petroleum. The heaviest portions of the distillate contain paraffine, and are called paraffine-oils. They also are mainly educts of the original oil ; they, however, contain a much larger proportion than the kerosene of the products of the decomposition of the oil. A tarry residue remains in the still, called " residuum." In other establishments the naphtha and illuminating oil are dis- tilled from the petroleum, and the dense oil remaining in the still, called "reduced petroleum," is draMrn out and used for lubrication. A large part of this dense oil from which the naphtha and illuminat- ing oil have been removed is " cracked," or destructively distilled, by 254 THE POPULAR SCIENCE MONTHLY. slacking the fires, and allowing the distillation to proceed so slowly that the dense portions of the vapors are condensed on the dome of the still, and, falling back upon the surface of the hot oil, are heated above their boiling-points, and decomposed into a lighter oil and a car- bonaceous residue. By continuing this process for several hours the oil has passed out of the still, leaving a quantity of residuum, as in the first instance. This cracking process is never complete, as a por- tion of the oil is cracked too much and another portion too little ; but the average gives a burning-oil of the proper density, color, etc., while in other respects it is greatly inferior to the oil that is not cracked. The reader will readily perceive that by mixing these constituent oils of the petroleum suitable for burning-oil, which have been very prop- erly called " normal " burning-oils, with different proportions of the cracked oils, a great variety of products may be obtained ; but I pro- pose in this article to speak of only three classes of burning-oils, and to show that these three classes may furnish oils that meet the de- mands of legal enactments, while at the same time they may be both very dangerous and very bad. The first class of oils mentioned that are distilled from the petro- leum unchanged consists of compounds of hydrogen and carbon com- bined in such proportions that the percentage of hydrogen is greater than in any other similar substances. In addition, they are very inert to chemical reagents, in this respect resembling paraffine or India-rub- ber. They may be washed with sulphuric acid or strong solution of caustic soda, and very completely purified ; but they are not acted on by either of these powerful reagents, and the product is a pure, color- less oil, with the odor of kerosene, and burning with a dazzling, white flame. The wick is burned but little more rapidly than that of an al- cohol-lamp. The flame does not smoke, neither does it emit any un- pleasant odor. These oils are safe, healthful, and economical ; in fact, they constitute the best and cheapest illuminating agent ever given to man. When the oils too heavy for illuminating oils are destructively distilled or " cracked," the product is largely contaminated with oils containing less hydrogen in proportion to the carbon, and which are not inert to chemical reagents like those just described. When these oils are treated with sulphuric acid, both the oil and the acid are de- composed. The sulphur and a part of the oxygen of the acid (S02) take the place of a part of the hydrogen of the oil, while this hydro- gen unites with the remaining oxygen of the acid and forms water. This sulphur and oxygen thus become constituents of the oil, and when the oil is burned they escape into the room as sulphurous oxide iden- tical with the fumes of burned brimstone. But this is not all : the sul- phur compounds, and the heavy, imperfectly cracked oils, soon impair the capillary attraction of the wick ; and, the flow of the oil being im- peded, the wrick becomes charred and coated with unburned carbon. CONCERNING KEROSENE. 255 This imperfect combustion produces smoke and imparts to the atmos- phere of the room unpleasant odors, and not infrequently leads to an explosion of the lamp and disastrous conflagrations. The steady flow of the oil through an unencumbered wick keeps the wick burner comparatively cool, and prevents the heating of the lamp and of the oil within it ; but, when the capillarity of the wick is impaired, the burner, lamp and oil within it become heated to a temperature that finally produces a distillation of the lighter portion of the oil, in many instances causing the flame to become dense and smoky ; sometimes streaming above the top of the chimney ; and, if not speedily ex- tinguished, resulting in an explosion and the destruction of the lamp. When the normal and cracked oils are mixed, the mixture partakes of the mingled characteristics of the constituents. The mixture may be nearly as good as the normal oils, or nearly as bad as the cracked oils. At the present time the common kerosene sold is either a " cracked" or a "mixed " oil, while the bulk of the high-test kerosene is supposed to consist of " normal " oil ; and, while any or all of these oils may be of any required test, they are of very various quality in other respects. The test of an oil, " high " or " low," represents the temperature to which the oil must be heated in order that a suitable quantity — usually one half-pint — may give off a sufficient amount of inflammable vapor to either flash or burn. The temperatures at which the same oil will flash and burn vary greatly with the character of the oil, being from 10° to 50° apart by Fahrenheit's scale. While it has been repeat- edly demonstrated, by several of the most eminent scientific experts now living, that the temperature at which an oil will burn is of no im- portance as an indication of its safety, this test is still in use in many localities. It is, however, the temperature at which the vapors will flash that is usually understood as the " test " of an oil, and it varies from 70° to 90° Fahr. in low-test oils to 120° to 140° in high-test oils. Experiment has repeatedly demonstrated that an oil that will give off vapors that will flash at 100° Fahr. is safe for any legitimate use. As painful and disastrous accidents are liable to follow the explosion of a lamp, and as the increased danger of explosion where low-test oils are used is obvious to any reflecting person, all efforts to restrict the manufacture or sale of unsafe oils by legislation have been hitherto directed toward the exclusion of very low-test oils from the market. In England such legislation has been based upon very elaborate re- search, and has been in the main successful ; but in the United States no less earnest though less carefully considered measures have been embodied in legislation which has resulted in the enactment of a great variety of statutes — giving to some States laws unreasonably exacting, to others wise provisions, while yet others have no legislative restric- tions whatever. Of course, such diverse enactments relating to a 256 THE POPULAR SCIENCE MONTHLY. single interest and question can not command the respectful considera- tion that uniform, just, and reasonable legislation would receive from all intelligent persons interested ; hence, it may be fairly stated that in this country legislation relating to the testing of petroleum is in in many respects unsatisfactory. It is not, however, to the generally unsafe character of low-test oils that I wish to call attention, but to those characteristics, not yet gen- erally or fully recognized, that render some oils that come within the legal provisions regarding test unhealthy and unsafe for use. The petroleum industry, in many of its aspects, is the product of development. This statement is true, not only as respects its vast magnitude, but also as pertaining to many of its details. The process of cracking had been employed in treating the distillates from coal before petroleum became an article of commerce ; yet petroleum, for a number of years following its discovery in large quantities, was uni- formly distilled into naphtha, normal burning-oil, and paraffme-oil. At that time but few uses were known for naphtha, and it was a drug in the market. At the same time the paraffine-oils were contaminated with more or less of the products of destructive distillation that were unavoidable attendants of even rapid distillation. These oils were consequently very poor lubricators, and, moreover, possessed a very unpleasant odor. They never commanded a good price and were slow of sale, for which reason it was obviously the interest of the manu- facturer to put into the burning-oil as large a proportion of the naph- tha as possible, for the purpose of holding in solution a maximum quantity of paraffine-oil. This often produced an oil unsafe from ex- cess of naphtha, but it was an oil consisting mainly of normal oil, and almost entirely of the educts of the petroleum. Sulphur had not then been observed as an impurity in burning-oil, although the same process of treatment was then used, but less carefully than now. As the original district of Oil Creek produced, at the end of ten years, a smaller proportion of the entire production of crude oil, the character of the burning-oil on the market in 1875 was different from what it was in 1865. At the former date the "lower country," so called in Butler and Clarion Counties, yielded an oil in some respects different from that of Oil Creek, and unequaled for the manufacture of burning- oil, inasmuch as the percentage of normal oils suitable for burning was found to be considerably greater. In five years the diminished pro- duction in the Butler-Clarion field, and the increased production of the Bradford district, together with the mixing of the entire production in huge tanks and pipe-lines without regard to quality, had entirely changed the relation of the amount of normal to that of cracked and mixed oils. The vast production and low price of crude oil had thrown the manufacture of petroleum into the hands of corporations controlling immense capital, and establishments in which the oil is handled in quantities proportionate to the enormous demand. Mean- CONCERNING KEROSENE. 257 time a method of refining petroleum bad been generally introduced, by which a large proportion of the total burning-oil produced consisted of mixed or cracked oils. Such a proportion of high-test oils as were demanded by the market was made, but the great bulk of the distil- late had been converted into a cracked or mixed oil. The petroleum was distilled but once, the naphtha was removed, and then the remain- der of the oil manipulated to produce such crude burning-oils as were desired, leaving in the still only a small percentage of residuum. These crude burning-oils were treated with sulphuric acid and caustic soda in such a manner as to produce the lightest colored oil possible, and they were further manipulated to bring the test within the legal requirements. As it was much less difficult to bring the mixed or cracked oils within the requirements of a burning rather than a flash test, the burning test has always found strong advocates among a cer- tain class of the manufacturers of petroleum. This method of manu- facture was well established, and the markets of the world were well accustomed to handling the various pi'oducts during that period when the bulk of the crude oil came from the Butler-Clarion district. But gradually, as has been stated, the major portion of the crude oil that flowed into the pipe-lines was no longer from the Butler-Clarion wells, but from those of Bradford. By the end of 1881 more than three quarters of the crude oil was Bradford oil, and the relative proportion has steadily increased. This change in the crude material has been accompanied by a corresponding change in the character of the prod- uct. Instead of mixed and cracked oils, consisting largely of normal burning-oil, the products of Bradford crude oil consist largely of the products of destructive distillation, and this is due to the fact that the petroleums of the Butler-Clai*ion and Bradford districts represent two extremes ; the first contains the smallest proportion and the latter the largest proportion of paraffine-oils of any crude petroleums found in large quantities. The proportion of cracked oils in the distillate from the Butler-Clarion petroleum was too small to injure the general qual- ity of the oil. In the Bradford distillates, on the contrary, the prod- ucts of destructive distillation give character to the whole. And not only is this statement true, but the proportion of high-test normal oils to be obtained at present from the pipe-line crude oil has gradually become so reduced that the best brands of oil on the market have deteriorated, until it is very difficult, if not impossible, to purchase an article of burning-oil equal in quality to the best offered for sale a few years since. All this time the requirements of law in regard to test have been met, perhaps it may be said, with increased faith- fulness. From the foregoing pages it must be manifest that any improve- ment in the increasingly bad quality of kerosene can be looked for only from one of two directions. Either it must come from the devel- opment of a new field for crude oil of superior quality, or from the in- TOL. XXTII. 17 25 8 . THE POPULAR SCIENCE MONTHLY. troduetion of new methods of manufacture. There are no indications at present that warrant any expectation that any material change is immi- nent in the character of the crude oil. The change must, therefoi'e, come from the introduction of different methods of manufacture. These methods need be neither novel nor unreasonably expensive. Cracked oils of good quality are nothing new, but I have never seen them made by one distillation and one treatment. Cracked oils should be finished by distillation, not treatment. A second distillation would enable the refiner to first remove the two volatile products of cracking and the heavy, uncracked portion of the paraffine-oil, besides destroying the sul- phur compounds. But such a technology would so far increase the cost of the oil that those employing it could not compete in the mar- ket with those who did not, except by virtue of the superior quality of their oil. It is in respect to this difficulty that the public weal could be well served by judicious legislation that in its broadest sense might well be considered sanitary legislation. It is a proper subject for physicians to determine, what the precise effects upon the general health may be resulting from the combustion in lamps and stoves of the vast quanti- ties of inferior oils that are daily consumed throughout the country. That the effect must be bad, determining a tendency to certain forms of disease and aggravating others, can not fail to be apparent to the most unreflecting person, especially when it is considered in how few instances any means are employed to remove from the apartment in which these oils are burned the products of combustion. When under such circumstances a pure oil is burned into pure water and carbonic acid, the atmosphere receives a sufficient burden ; but when to these are added vapors of burned sulphur and a variety of irritating vapors with smoke, the eyes, lungs, and nostrils pay a heavy tribute. Added to this is the new source of danger from fire resulting from explosions arising from imperfect combustion — a source of danger not hitherto recognized in legislation, but of not infrequent occurrence. For the reasons stated, it appears that the health and safety of the public, and the protection of those manufacturers who would make a radical change in the methods of manufacture now employed, alike demand legislation that will exclude from the market not only oils that are unsafe from excess of naphtha, but those which in their gen- eral character are unhealthful to use and unsafe from other causes. Such legislation should be based upon an exhaustive scientific exami- nation of the subject, with a view to placing the fewest restrictions upon the manufacture and sale of these oils consistent with the de- mands of public health and safety. Such an investigation can best be undertaken by the General Government, to be followed by such amend- ments to the national legislation now in force as the results might justify. Such national legislation, based upon a comprehensive knowl- edge of the subject, could not fail to be followed by a general revision THE CHEMISTRY OF COOKERY. 259 of State and municipal legislation throughout the country and the en- actment of uniform laws that, while securing the adequate protection of the public, would no longer embarrass by needless and unreasonable requirements the manufacture and sale of articles in universal demand. +*+ THE CHEMISTRY OF COOKERY. By W. MATTIEU WILLIAMS. LI. — MALTOSE AS A COOKING AGENT. A FEW years ago the " farmer's friends " were very sanguine on the subject of using malt as a cattle-food, and at agricultural meetings throughout the country the iniquitous malt-tax was elo- quently denounced because it stood in the way of the great fodder- reform. The malt-tax was repealed, and the subject fell out of sight and hearing immediately thereafter. Why was this ? The idea of malt-feeding was theoretically sound. By the malting of barley or other grain its diastase is made to act upon its insoluble starch, and to convert it more or less completely into soluble dextrine, a change which is absolutely necessary as a part of the business of digestion. Therefore, if you feed cattle on malted grain instead of raw grain, you supply them with a food so prepared that a part of the business of digestion is already done for them, and their nutrition is thereby advanced. From what I am able to learn, the reason why this hopeful theory has not been carried out is simply that it does not "pay." The advan- tage to the cattle is not sufficient to remunerate the farmer for the extra cost of the malted food. This may be the case with oxen, but it does not follow that it should be so with human beings. Cattle feed on grass, mangel- wurzels, etc., in their raw state, but we can not ; and, as I have already shown, we are not even graminivorous as they are — we can not digest raw wheat, barley, oats, or maize. We can not do this because we are not supplied with such natural grinding apparatus as they have in their mouths, and we have a much smaller supply of saliva, besides a shorter alimentary canal. We can easily supply our natural deficiencies in the matter of grinding, and do so in our flour-mills ; but at first thought the idea of finding an artificial substitute for saliva does not recommend itself. When, however, it is understood that the chief active principle of the saliva so closely resembles the diastase of grain that it has received the name of animal diastase, and is probably the same compound, the aspect of the problem changes. Not only is this the case with the secretion from the glands sur- 26o THE POPULAR SCIENCE MONTHLY. rounding the mouth, but the pancreas, which is concerned in a later stage of digestion, is a gland so similar to the salivary glands that in ordinary cookery both are dressed and served as " sweetbreads," and its secretion, the pancreatic juice, is a liquid closely resembling saliva and containing a similar diastase, or substance that converts starch into dextrine, and f rom dextrine to sugar. Lehmann says, " It is now indubitably established that the pancreatic juice possesses this sugar- forming power in a far higher degree than the saliva." Besides this there is another sugar-forming secretion, the " intestinal juice," which assists the graminivorous animals in the digestion of raw grain. This being the case, we should, by exercising our privilege as cooking ani- mals, be able to assist the digestive functions of the saliva and the pancreatic and intestinal secretion, just as we help our teeth in the tlour-mill ; the means of doing this is offered by the diastase of malt. In accordance with this reasoning I have made some experiments on a variety of our common vegetable foods, by simply raising them (in contact with water) to the temperature most favorable to the convert- ing action of diastase) 140° to 150° Fahr.), and then adding a little malt-extract or malt-flour. This extract may be purchased ready made or may be prepared by soaking crushed or ground malt in warm water, leaving it for an hour or two, or longer, and then pressing out the liquid. I find that oatmeal-porridge, when thus treated with malt or malt- extract, is thinned by the conversion of the bulk of its insoluble starch into soluble dextrine ; that boiled rice is similarly thinned ; that a stiff jelly of arrowroot is at once rendered watery, and its conversion into dextrine is demonstrated by its altered action on a solution of iodine. Instead of instantly striking a blue-black color on admixture, only a slight brownish tinge is displayed, and not even this when the temperature has been carefully maintained. Sago and tapioca are similarly changed, but not so completely as arrowroot. This is evidently because they contain a little nitrogenous matter and cellulose, which, when stirred, give a milkiness to the other- wise clear and limpid solution of dextrine. Pease-pudding when thus treated behaves very instructively. In- stead of remaining as a fairly uniform paste, it partially separates into paste and clear liquid, the paste being the cellulose and vegetable casein, the liquid a solution of the dextrine or converted starch. Tur- nips, carrots, potatoes, etc., behave similarly, the general results show- ing that, so far as the starch is concerned, there is no practical difficulty in obtaining a practically sufficient amount of conversion of the starch into dextrine by means of a very small quantity of maltose. " Hasty-pudding," made of boiled flour, is similarly altered ; gener- ally speaking, the degree of visible alterations is proportionate to the amount of starch, but, the smaller the proportion and the greater that of cellulose, the more slowly the change occurs. THE CHEMISTRY OF COOKERY. 261 I have made a malt-porridge by using ground malt, from which I sifted out as much husk as possible, instead of oatmeal. I found it rather too sweet ; but, on mixing about one part of malt-flour with four or more of oatmeal, an excellent and easily-digestible porridge was obtained, and one which I strongly recommend as a most valuable food for strong people and invalids, children and adults. Further details of these experiments would be tedious, and are not necessary, as they display no chemical changes that are new to science, and the practical results may be briefly stated without such details. I recommend — 1. The production of malt-flour by grinding and sifting malted wheat, malted barley, or malted oats, or all of these, and the retailing of this at its fair value as a staple article of human food. Every shopkeeper who sells flour or meal of any kind should sell this. 2. That this malted flour, or the extract made from it as above de- scribed, be mixed with the ordinary flour used in making pastry, bis- cuits, bread, etc.,* and with all kinds of porridge, pea-soup, and other farinaceous preparations, and that when these are cooked they should be slowly heated at first, in order that the maltose may act upon the starch at its most favorable temperature — 50 or 60° below the boiling- point. 3. When practicable, such preparations as porridge, pastry, pea- soup, pease-pudding, etc., should be prepared by first cooking them in the usual manner, then stirring the malt-meal or malt-extract into them, and allowing them to remain for some time. This time may vary from a few hours to several days — the longer the better. I have proved by experiments on boiled rice, oatmeal porridge, pease-pudding, etc., that complete conversion may thus be effected. When the temper- ature of 140° to 150° is carefully obtained, the work of conversion is done in half an hour or less. At 212° it is arrested. At temperatures below 140° it proceeds with a slowness varying with the depression of temperature. The most rapid result is obtained by first cooking the food as usual, then reducing its temperature to 150° and adding the malt flour or extract, and keeping up the temperature for a short time. 4. Besides the malt-meal or malt-flour, which I presume will be preferably made from barley, I recommend the manufacture of what I may call " pearl-malt," that is, malt treated as barley is treated in the manufacture of pearl-barley. This pearl-malt may be very largely used in soups, puddings, and for other purposes evident to the practical cook. * I have lately learned that a patent was secured some years ago for "malt-bread," and that it is still obtainable from many bakers, who make under a license from the patentee. The " revised formula " for this, which I have just obtained, says : " Take of wheat-meal, six pounds ; wheat-flour, six pounds ; malt-flour, six ounces ; German yeast, two ounces ; salt, two ounces ; water sufficient. Make into dough (without first melting the malt), prove well, and bake in tins." Malt-flour is also sold, but at fancy prices, ab- surdly beyond its just value. 262 THE POPULAR SCIENCE MONTHLY. It may be found preferable to the malt-flour or meal for some of the above-named purposes, especially for making a pur&e like Rumford's soup. I strongly recommend such a soup to vegetarians, i. e., the Rum- ford soup No. 1, already described, but with the admixture of a little pearl-malt with the pearl-barley (or malt-meal failing the pearl-malt). A small proportion of malt flour, one twentieth for example, has a considerable effect, and if a fancy price is to be paid for it such a pro- portion may be used ; but, if it comes into sufficient demand to be sub- ject to wholesome competition, larger proportions up to one fourth will be desirable. In my experiments I used the malt-extract in order to render the result visible, but this is not necessary in practice. Either the extract or the flour may be used, as may be convenient. In all cases time should be allowed for the conversion of the starch to take place before raising the temperature to 212°, keeping in view the principles above explained as regards the temperature and time required for conversion. I have not yet met with any malted maize commercially prepared, but the experiments that I have made on a small scale show that it is a very desirable product. I name it here and now (January 8, 1885) to prevent its becoming patented, as there are so many greedy people who rush to the Great Seal Office with any idea tbey may pick up, however trivial. Any previous publication of the invention is suffi- cient to frustrate the monopoly. The same applies to the other uses of malt that I have specified. I am still unable to speak positively as to the efficiency of vegeta- ble diastase in breaking up or effecting the hydration of cellulose and its conversion into sugar ; but the following facts are promising : I treated sago, tapioca, and rice with the maltose as above, and found that at a temperature of 140° to 150° all the starch disappeared in about half an hour, as proved by the iodine test. Still the liquid was not clear ; flocculi of cellulose, etc., were suspended in it. I kept this on the top of a stove several days, the temperature of the liquid varying from 100° to 180°, while the fire was burning, and falling to that of the atmosphere at night. The quantity of the in- soluble suspended matter sensibly diminished, but it was not entirely removed. This has led me to make further experiments, now in progress, on the ensilage of human food, with the aid of diastase. I am packing various kinds of vegetable food in small silos, adding to them varying proportions of malt-flour or malt-extract, and I hereby declare, for the benefit of would-be patentees, that this invention, whether worthless or otherwise, is mine, and can not be secured by them, as I have witnesses of the date of this writing and copy thereof. I shall certainly not patent this or any of the above inventions myself, and will prevent others from interfering with their free use in the improvement and cheapening of our food-supplies. I am also treating such vegetable SKETCH OF BR. ALFRED E. BREHM. _ 263 food material with various acids for the same purpose, and make the same claim in reference to this. When by these or other means we convert vegetable tissue into dextrine and sugar, as it is naturally converted in the ripening of a pear, and as it has been artificially converted in our laboratories, we shall extend our food-supplies in an incalculable degree. Swedes, turnips, mangel-wurzels, etc., will become delicate diet for invalids, horse-beans better than beef ; delicate biscuits and fancy pastry, as well as ordinary bread, will be produced from sawdust and wood-shav- ings, plus a little leguminous flour. This may be done now. Long ago I converted an old pocket- handkerchief and part of an old shirt into sugar. Other chemists have done the like in their laboratories. It has yet to be done in the kitchen. I should add that the sugar referred to in all the above is not cane- sugar, but the sugar corresponding to that in the grape and in honey. It is less sweet than cane or beet sugar, and a better food. I now conclude this series, with the expression of my firm convic- tion that the application of chemical science to cookery is capable of vastly extending and improving our food-supplies, and thereby of greatly increasing the numbers of prosperous human beings capable of living on the earth. This, however, demands a great deal of further experimental research. I have done so little of this in proportion to my suggestions for further research that I fear my readers will liken these papers to those others found by Prince Hal in the pockets of Jack Falstaff : " Oh, mon- strous ! but one half -pennyworth of experimental bread to this intol- erable deal of speculative sack ! " -+++- SKETCH OF DR. ALFEED E. BREHM* ON the 11th of November last there died a man who is entitled by every consideration to a distinguished place in the pages of a sci- entific journal. For, whatever Alfred Brehm may have lacked in the systematic formalism of technical zoologists, it can not be denied that he was really great and even unique in the sympathetic comprehension of animals as living beings. Other works similar to the " Thierleben " (" Animal-Life ") exist, and have great merit, but in this sympathetic aspect they are far behind this ten-volumed work. It in no way de- tracts from his merit that he had to call in specialists to assist him in describing the insects and the lower animals ; for these departments are a world in themselves, requiring a whole lifetime for their study, * We are indebted for the materials of this sketch to an affectionate memoir of Dr. Brehm, published by Dr. Karl Muller in "Die Natur" of December 21, 1884. 26+ THE POPULAR SCIENCE MONTHLY. and his life was too short to compass everything. But he opened a new door to the vertebrate world ; and, if the question be asked how it was possible to give so large and expensive a book permanent cur- rency with the German public, the answer must be found in tbe sym- pathetic element of the work, which brought a new world so near to us, and so inspired it that the soul-life of animals is no longer an empty sound. It was Alfred Brehm's privilege to grow up among the most fa- vorable circumstances conceivable for a nascent naturalist. He was born on the 2d of February, 1829, at Renthendorf, near Neustadt, on the Orla. He could have had no better guide to his future course than his father, the pastor of the parish, who as " Father Brehm " was known among the older ornithologists of his time as indisputably one of the most distinguished observers of the habits of birds. What the no less eminent ornithologist Z. F. Naumann was for Anhalt and its vicinity, Christian L. Brehm was for Thuringia, a favorite region for all lovers of birds, and full of inspiration for youth having a taste for natural his- tory. This inspiration could not fail to work deeply in so receptive a spirit as the son possessed, and he thus grew up literally in an ornitho- logical atmosphere, in which his especial taste and aptitude later took tirm root. Thus were early developed in him the future ornithologist and the self-reliant, independent spirit. In 1847 the famous and wealthy African traveler, Baron J. W. von Midler, proposed that he go with him to Africa as his ornithological assistant. It was known that young Brehm was already not only an accomplished ornithologist, who was acquainted with the voices of all the birds, but that he was also a splendid shot, who had himself contributed many precious addi- tions to his father's great collection of European birds, which was esti- mated to contain nine thousand specimens. Brehm had just passed his abiturient examinations when Midler's invitation came to him ; and, as his father had nothing to say in opposition to it, he immediately made his own conditions and decided to go. The journey was to be under- taken at once, and to last five years. Brehm did not return till 1852, after he had explored Egypt, Nubia, and Eastern Soudan, countries that have always had great attractions for zoologists, especially for ornithol- ogists. Here is the resort of many birds which migrate from Europe to seek a winter home in summer-land, and also the abode of a multitude of African species which never leave that quarter of the world. Nau- mann also sent his apostles hither at about the same time, and one of them, the youthful Vierthaler, who has long been resting in Nubian soil, described with much spirit, in " Die Natur " for 1852, the kind of a bird- paradise which he found on the banks of the White and the Blue Nile. It was given to young Brehm alone comprehensively to depict this life in his first publication, "Reise Skizzen aus Nordost Africa" ("Travel- Sketches from Northeastern Africa"), three volumes, Jena, 1853. After he had attended the University of Jena, and had subsequently SKETCH OF DR. ALFRED E. BREHM. 265 studied the treasures of the Zoological Court-Museum at Vienna, under the guidance of the recently deceased Leopold Joseph Fitzinger, its cus- todian, he became as it were dead for any other than a scientific world, and only the innate energy of his character enabled him to maintain a fixed purpose in life. For every effort to establish himself was de- feated in consequence of his having so long lived a wandering life in Africa — as is generally the case with extensive travelers, he had no taste tor a sedentary career — and it was, therefore, not strange to see him starting off again in 1856. This time the field of his researches was Spain and its bird-life, which a brother of his had already studied to some extent. Then, in order to study an opposite region to this, he went in 1860 to the North and visited Norway and Lapland. The fruit of this journey was " Das Leben der Vugel" ("The Life of Birds"), Glogau, 1861, and a general fame as a traveler and writer. He soon afterward received an invitation from Duke Ernst of Saxe-Coburg- Gotha to go with him on a hunting-journey to Bogosland and Abys- sinia, which was begun in 1862. At the request of the duke, he worked up the collected impressions and observations of this hasty expedition in 1863 into "Ergebnisse einer Reise nach Habesch " ("Results of a Journey to Habesch"), Hamburg, 1863. The physiognomic and sym- pathetic tastes characteristic of Brehm are also prominent in this book. He was at about the same time appointed director of the Thiergarten in Hamburg, a position which furnished him an excellent opportunity to add to his store of zoological observations. It must have been of much value to him, for he had already conceived the idea of publishing an " Illustrirtes Thierleben " on a grand scale. Nevertheless, he sur- prised the world four years afterward by voluntarily giving up this position and turning his back on Hamburg. Brehm was also too busy at that time with his own enterprises to be a*ble to devote his whole powers to responsible positions. His " Thierleben " occupied him closely, and required him to review the whole store of observations which he had collected, especially in his later years. What he himself thought of the subject is shown by the following passage of the prospectus which he wrote for the second edi- tion, in 1876 : " The activity of science has also worked fruitfully on the public desire for knowledge. The nearer view that is given to it of animals in Nature (in zoological gardens), the word spoken from the professorial chairs of the schools, and its multiplied repetition in writing and picture, have — each supplying its part — contributed to spread, with the knowledge of animals, interest in them and apprecia- tion of them. Thus, man's approach to the forms of creation nearest related to him, his recognition of the existence and life of animals, has taught him that this circle of living beings includes its own life within itself, and simply with the entrance into it has much light been shed over the problem of his own origin, which a rigid dogma had long kept in darkness." In this passage he evidently referred to 266 THE POPULAR SCIENCE MONTHLY. the then still new doctrine of descent of Darwin, but a sure tact pre- served bim from tbe mistake of permitting it to bave any influence on bis great work. Tbe prospectus also gives information on tbis sub- ject ; for be says at tbe close of it, in tbe name of tbe publisher : " The question will come up with every one of what will be tbe attitude of this work toward tbe movement of our time which is leaving away bebind itself the mark of exact research, and is losing its head in the regions of speculation. On tbis subject it is proper to remark that the author has not followed this movement in the present work ; that he has kept aloof from the strifes of tbe learned and from brilliant conjectures ; and in tbe well-understood interest of the layman, who will seek instruction through him, he has confined himself to demon- strated facts and established observations. No one, therefore, need fear that his faith or conscience will be damaged, or that he will have reason to be afraid on account of bis similarity with monkeys." Brehm was also aware that he must in his treatise abandon the region of the systematic in which all other text-books of zoology were cast. " With the abandonment of the sterile domain of the systematic," he says again in his prospectus, " a rich field of observation has opened out before the eye of the naturalist." But be well understood that he could not include everything with this one-sided view, and knew that the naturalist could not be a fast-bound teacher, but must lead the life of a hunter and wanderer, as he himself had done till then. He con- siders expressly, in the preface to the second series of his " Tbierleben," tbe manner in which readers will have to judge it : " The ' Tbierleben ' is not afraid of a stringent criticism. Whoever seeks in it what the title and the opening pages will justify bim in looking for will not find himself deceived ; for, if he will always keep the title in mind, he will not seek there for what he can not find." He was so fortunate as to have the aid, in preparing his first edition, of the gifted animal-painter Robert Kretscbmer, of Leipsic. The two men were well acquainted with each other. They had both been attached to the Abyssinian expedition, Kretschmer as its artist ; and the water-color illustrations of it, painted on the spot, which he brought home with him, are among the most beautiful of their kind. Brehm was, therefore, quite right in calling his first edition an illustrated " Tbierleben " ; those fresh, lively pictures, painted with such grasping perception and free- dom from restraint, contributed greatly to pave its way to tbe public ; without them, the success of tbe book, notwithstanding its excellent contents, would have been much smaller. Brehm wrote the first five volumes of his book between 1863 and 1868, while Oskar Schmidt and C. L. Taschenberg prepared the sixth volume, containing invertebrates. A second edition, in ten volumes, was published in 1868, and the follow- ing years. The great pains with which the whole work was gradually pushed to completion bore good fruit, and, when we state that the book was translated into most of tbe living literary languages, it is not SKETCH OF DR. ALFRED E. BREHM. 267 necessary to say anything of the appreciation in which it was held by German-speaking people. A popular edition in three volumes was published 1888 to 1872. During the publication of this great work, Brehm resided in Ber- lin, where, as in Hamburg, he occupied himself with introducing the public to the forms of life which were described in so masterly a man- ner in the " Thierleben." A joint-stock company was formed, with a capital of nine hundred thousand marks, for the establishment of a great aquarium, of which Brehm was given the direction. The posi- tion, however, did not suit him, for he found himself too closely hedged up for his comfort. The establishment he founded still re- mains one of the famous sights of the city, but he withdrew from it, to devote himself again to his literary labors, which he varied with lectures in different cities. Among his literary enterprises is a book in two volumes on " Captive Birds," which was published at Leipsic and Heidelberg in 1872. Brehm again left his country, to pursue zoological researches, in 187G, when at the suggestion of Dr. M. Lindermann an expedition to West Siberia was organized in the Bremen Union for Arctic Explo- ration, the cost of which was defrayed pai*tly by the Union and partly by private contributions and the Russian merchant Michaelovich Si- biriakoff. The expedition consisted of Dr. O. Finsch, Dr. A. Brehm, and Count Waldburg-Zeil-Trauchburg, who joined it as a volunteer. Its route extended over the Ural across the Ischim Steppe, and along the Irtish to Semipalatinsk, to the Arrat Mountains, through the land of the Kirghiz to the Dzungarian Ala-Tau, thence to Nor-Saissan, then over the Chinese Hoch-Altai and through the Altai crownland to the Obi, and lastly across the Tundra to the country of the Ostiaks and Samoyeds, whence Brehm returned home by way of St. Peters- burg, where he stayed a short time to deliver lectures. Reaching home safely, he also delivered lectures there, upon the journey he had just performed. In the same year, 1877, he accepted an invitation from the Crown-Prince Rudolph of Austria, to whom he had dedi- cated the second edition of his " Thierleben," to go with him on an excursion to the forests of the middle Danube, of which the crown pi*ince afterward published a sketch. Two years later, in 1879, he accompanied the crown prince to Spain. In 1880 he, on his own ac- count, visited Noi'th America to deliver lectures. This visit had an unfortunate ending ; he was attacked by a violent fever ; and after he returned home, having gone to Renthendorf, he was prostrated with a disease of the kidneys which soon proved fatal. This prema- ture ending of his life was the more deplorable, because the restless naturalist was engaged on a new natural history of animals, which was to have a very wide scope. In him passed away one of the noblest of Germans, a man to whom the animal world was a world full of spirit and inspiration. 268 THE POPULAR SCIENCE MONTHLY. EDITOR'S TABLE. LIBER TY IN ED UCA TION. DR. McOOSH has published an ar- gument on freedom in the higher education. He bad discussed the subject with President Eliot before the Nine- teenth Century Club, and he has since issued a pamphlet, entitled " The New- Departure in College Education, being a Reply to President Eliot's Defense of it in New York, February 24, 1885." The traditional collegiate system which has descended to us from old mediaeval and monastic times, so little impaired in its essential method, is now brought to the test of modern ideas. Not only is it a question of introducing and or- ganizing modern studies in place of the classical studies, that are losing their hold upon the cultivated mind of the age, but this involves an inquiry into the theories and principles of the older and the newer education as to how far we should go in the direction of a more pliant, adaptive, and liberal system, and how far students are to have liberty of choice among the subjects of collegiate study. Dr. McCosh argues against freedom in the higher education, taking the ground that has ever been taken against the progress of liberty — that it will be abused and run into license. As politi- cal liberty was resisted because it would destroy government, and lead to an- archy ; as religious liberty was resisted because it would destroy the Church and put an end to religion ; and as the liber- ty of the press was resisted because it would subvert public order — so the lib- erty of study is now opposed because it will degrade education and destroy the colleges. To all this, the reply dic- tated by the world's experience is sim- ply that, while there are undoubted objections to liberty, its advantages outweigh its drawbacks. Dr. McCosh maintains that, if the students are left free to elect their subjects, they will choose those which are easiest, and therefore most worthless for purposes of mental cultivation. But this is con- trary to both reason and experience. President Barnard, of Columbia Col- lege, in a passage appended to this arti- cle, testifies that students left free do not choose the easier subjects. But the reason of the case is, that what is hard to one student is easy to another ; and this fact, with its implications, is the key to the movement in behalf of great- er liberty in the choice of studies. Dr. McCosh makes little concession to those rights of individuality which originate in personal aptitudes and diversities of mental constitution, and which impel students to different lines of effort. He would enforce a common method upon all under a theory of mental discipline, rejected by reason and experience, and fortified only by long tradition. Dr. McCosh protests that he is not behind the age or an obstructive, and is "for freedom quite as much as Dr. Eliot is," and he allows "a certain amount of choice of studies," but this is in strict subjection to the classical ideal and the old college practice. There is talk in this option contro- versy about a great number of things, but the issue is over compulsory Greek and Latin. It is a fight of the classi- cists, and, so long as they can force the dead languages, they care very little what else comes or goes. Classical edu- cation knows nothing of this modern spirit of liberty. It has ever been closely associated with priestly domina- tion, with religious intolerance, with despotic collegiate authority, and arbi- trary state regulation. In the old and powerful English universities the dead languages are the one tiling that has EDITOR'S TABLE. 269 been forced for centuries. They have been legislated as the tests of scholar- ship, the credentials of culture, and the badges of gentility. That the classical spirit should be one of arrogance and tyranny, and adverse to liberty, is suf- ficiently explained by the history of the old universities. There is much talk about the freedom of the German uni- versities ; but, so far as classics are con- cerned, their policy is one of simple, unmitigated despotism. Students, of course, are left free to attend lectures and recitations or not, as they please, and to study much as they like; but what does that amount to when they can not get into the universities with any chance of success except through the gymnasium, where they are subjected to years of unrelenting classical drill ; and, if they do not graduate in conform- ity to high classical standards, are un- able to get places under the state in either the church, the army, or the civil service? The educational system of Germany is an iron despotism of a mili- tary state. Dr. McOosh understands this ; and, true to his classical instinct, would be willing to concede the utmost option to Harvard University if Massa- chusetts would but adopt the German plan. He says : I know that in Germany they produce scholars without requiring a rigid attendance, and I rather think that in a few American colleges they are aping this German method, thinking to produce equally diligent students. They forget that the Germans have one power- ful safeguard which we have not in America. For all offices in church and state there is an examination by high scholars following the college course. A young man can not get an office as clergyman, as teacher, as postmaster, till he has passed by that terrible examining bureau; and, if he is turned by them, his prospects in life are blasted. Let the State of Massachusetts pass a law like the Prussian, and Harvard may then relax attendance, and the State will do what the colleges have neg- lected to do. The following passages, from a paper read before the Kegents of the Univer- sity of New York by President Barnard. of Columbia College, is a sufficient an- swer to the objections urged by Dr. McCosh : Every new subject of study which has been admitted in the college course since the century began has been admitted in acknowl- edged violation of the theory on which the course is assumed to have been originally founded. Chemistry has been admitted, for instance, into the course, on the ground that it is important that every well-educated man should know something about the elementary composition of the matter which surrounds him ; anatomy and physiology, because he ought to understand the structure of his own frame and the functions of its several organs ; and mineralogy, geology, botany, physics, etc., for similar utilitarian reasons. So great is the multiplicity of subjects at present taught as to destroy altogether, especially in later years, the character claimed for the col- legiate course as a system of mental disci- pline. It is time, as it appears to me, that we should revise our theory of collegiate educa- tion, with a view to make it conform a little more nearly to our actual practice ; or that we should modify our practice to make it harmo- nize more nearly with our theory. The most judicious course, apparently, would be to ad- mit, to some extent, both species of change at the same time ; and with this would neces- sarily follow the introduction into the system of instruction of the element of plasticity, permitting it to be varied in its character to accommodate the exigencies of different minds. The doctrine that all varieties of mind may be profitably subjected to the same educational regimen is a doctrine which it is not safe to admit, unless we confine its applica- tion to the most elementary stages. The true theory of education is not that theory which aims professedly to secure for all minds iden- tically the same description of development and to force every mind into absolutely the same mold ; but that, on the other hand, which anticipates, as inevitable, differences which no external influences can ever compel effectually to disappear, and which adapts its culture to these ineradicable and irrepressible differences. The first business of education is, there- fore, to find out what the individual is fit for ; the next is to make the most of him in that for which he is fit, and, according to this true theory of a subject which plausible specula- tion has done very much to obscure, a special system or training, adapted to the idiosyncra- sies of the individual, is just as distinctly in- 270 THE POPULAR SCIENCE MONTHLY. dicated for the latter years of a liberal educa- tional culture as a general one, equally en- forced on all, is for the earliest. And it further follows that, if at this later period the student is permitted to follow the bent which his previous training has served to develop, his choice will fall upon those studies which are in harmony with his bent without any reference to the question whether they are, in the common sense of the word, "easy" studies or " difficult." For these terms "easy" and "difficult" as applied to mat- ters which concern the understanding, admit of two quite different modes of definition. No mental pursuit is easy if it be distaste- ful, no matter how small the labors its prose- cution demands ; and no similar pursuit is difficult if pleasing, even though to follow it may exact the severest and the most persist- ently sustained exercise of the faculties. And, in corroboration of the truth of this proposi- tion, it may here be stated that, in Columbia College, under the system which permits the members of the senior class to select, for the most part, studies which they prefer to pur- sue, there is no lack of volunteers for a sub- ject commonly reported to be so difficult and forbidding as the calculus, or as obscure as the metaphysics ; nor is there, on the other hand, any observable predominance in the number who select a branch so fascinating as physics, or so practical as technology or chem- istry. The distribution has been, in fact, approxi- mately equal among all the studies presented for option. And this result is one which we may reasonably look for when parallel courses of study are offered to the choice of the stu- dent during the later years of the academic course, whatever might be true if the offer were made at the beginning. For the effect of the early years of training is to bring out the character of each individual mind, and to determine what are its native idiosyncrasies, and what it is possible to make of it. And though the doctrine that all the faculties of all minds should be developed as far as pos- sible by appropriate educational exercise and discipline is a true doctrine, yet the doctrine that all faculties of all minds are equally ca- pable of development is a fallacy which no enlightened educator will think of maintain- ing. That every faculty should receive its fair amount of fostering attention is certainly just and right, but to expect that this fair amount or that any amount of individual culture, however laborious, will secure to every in- dividual an equal power or chance of success in any given direction — as, for instance, in poetry or mathematical research — is as unrea- sonable as to expect that every sapiing in a nursery may, by proper care, be made equally prolific of fruit. After all that has been 6aid about the desirability and the importance of symmetrical mental development, and of the duty of shaping the educational culture with a view to secure such a development, the sim- ple fact is that all minds develop themselves unsymmetrically, just as certainly as that dif- ferent minerals crystallize into different geo- metrical figures ; and that it is just as hope- less for the educationist to look for that ideal conformity and perfection of mental propor- tion among his pupils which has been so much insisted on as the end at which educa- tion should aim as it would be for the chem- ist to attempt by his science to compel all his salts to crystallize into spheres. The great evil of the invariable curricu- lum of study in our colleges at the present time is that it makes it impossible, at least after the end of the second year of the course, to teach any subject with satisfactory thor- oughness. From an examination of the pro- gramme of instruction in Columbia College for the junior and senior years — I select my own college rather than another that ray re- marks may not seem invidious — it appears that if every student were compelled to take every subject, and if to every subject should be given an equal proportion of the available time, no single subject, if pursued continu- ously, could occupy a longer period than about a month. How is it possible to expect results satisfactory either to instructor or to learner from such a state of things as this ? There is no remedy lor the evil but that of permitting the student to concentrate his at- tention upon those subjects which are most in harmony with his native bent, and to leave the others to those to whom they in turn may be more acceptable. BE LA YE LEY E ON SOCIALLSM. "No apology is needed for printing the long article of M. de Laveleye in reply to Herbert Spencer, together with the latter's brief rejoinder. The Bel- gian state socialist is a man of mark, who believes in the extension of the powers of government for the general purposes of philanthropy; and it was natural that he should see the need of breaking the force of Spencer's argu- ment. But, quite regardless of that result, his paper is of interest as re- vealing the condition of mind of a man admitted to he strong in politics EDITOR'S TABLE. 271 and economics, but who shows such a want of familiarity with the elements of social science as gives confusion to his exposition. Notwithstanding its merits, looseness and inaccuracy in im- portant parts of his paper must go far to impair our confidence in the integ- rity of his intellectual work. What trust, for example, can we have in the information or the thinking of a man who says, ''Darwin borrowed his ideas of the struggle for existence and the survival of the fittest from Malthus, from whom he also drew his theories of evolution and transform- ism"? Now, "the struggle for exist- ence " is certainly not an idea belong- ing either to Darwin or Malthus, but is far older than both. And so also with the principle of the "survival of the fittest"; it is a formula of Herbert Spencer, adopted by him to represent the same idea that Mr. Darwin ex- presses by the term "natural selec- tion " ; but the conception is found in the writings of the earlier naturalists, and what the modern thinkers have done is simply to work out new and important views of their results. M. de Laveleye constantly speaks in his article of "Darwin's idea," and constantly misconceives it. What Mr. Darwin did was to show how the ideas or principles or conditions of nature known as the struggle for existence and the survival of the fittest, together with heredity and variation, give rise to new species of plants and animals. It was an idea belonging strictly to the sphere of biological science, and aiming to ac- count rationally for the great diversi- ties of kinds among organic beings. M. de Laveleye not only misappre- hends "Darwin's idea," of which he is constantly talking, but speaks of it as something seized upon by Herbert Spencer and applied by him to human society. But, in the first place, Dar- win had nothing to apply ; and, in the second place, Spencer was in the field long before him. The struggle for ex- istence and the survival of the fittest were ideas which Spencer had devel- oped in their social applications, tracing out their results and assigning their limitations in his book upon human so- ciety, of 1851 ; while " Darwin's idea," belonging in quite another field, was not enunciated till 1859. But this laxity of thought and mis- information affecting the fundamental conception of his argument go fur- ther. Not only does he misapprehend the "Darwinian idea," which is in fact entirely irrelevant to his argument, and not only does he constantly make Spen- cer the follower of Darwin, where Spencer was the actual predecessor, but he discloses an ignorance of the prin- ciples he professes to deal with, in their social bearings, which is somewhat sur- prising in a man who ventures to take issue with the leading sociologist of the age. He accuses Spencer of borrowing from Darwin, and applying to society an inhuman principle, which reverses all the equities of government and gives license to the worst of crimes. He says, " If it be really advisable that the law of the survival of the fittest should be established among us, the first step to be taken would be the abolition of all laws which punish theft and mur- der." And does M. de Laveleye really consider that it is optional with any- body whether the principle of the sur- vival of the fittest shall be established in society or not ? Are not the princi- ples of the struggle for existence and the survival of the fittest simple demon- strated facts of nature, as old as men's observations of the economy of life upon earth,' and no more to be escaped than temperature, the atmosphere, or gravitation ? Because the law of gravi- tation is destructive, and maims and kills people daily, and everywhere, and without remorse, is the question to be raised whether or not it is to be es- tablished among us ? And will M. de Laveleye maintain that the only way " to establish among us this heartless and cruel law of gravitation" is to give everybody a license to kill ? The law 272 THE POPULAR SCIENCE MONTHLY. of gravitation is established, and, with all its deadly results, it is a law of infi- nite beneficence. Nothing remains for man but to accept it and heed it : if it causes wounds when he stumbles, it is, nevertheless, the condition by which he walks; he is to avoid its injurious ef- fects and secure its useful effects. Na- ture, of which man is a part, is a mixed system, in which good comes out of evil, and suffering is made tributary to ever-increasing beneficence. The prin- ciples of the struggle for existence and the survival of the fittest are inexorable ordinances of Nature, full of violence and death, but through which the prog- ress and improvement and elevation of life upon earth have been accomplished. They were in operation upon a vast scale countless thousands of years be- fore man appeared. They have been in operation in his development many thousands of years before he began to take a conscious and intentional part in the work of his own elevation ; and they must continue in operation as long as the present order of natural things prevails, and the movement is upward and onward toward greater good. The sole question is, whether these great laws are to be wisely recognized and made use of by man in furtherance of those ameliorations to which they have already so immensely contributed. Only gross inappreciation of the subject, or sheer intellectual perversity, could as- sume that these principles require the abolition of the penal restraints of crime in organized society. LITERARY NOTICES. Jeli-t-Fish, Star-Fish, and Sea-Urchins: Being a Research on Primitive Nervous Systems. By G. J. Romanes. New York: D. Appleton & Co. Tp. 323. Price, $1.75. The main object of this work by Pro- fessor Romanes is the description of the investigation of the physiology of the ani- mals lowest in organization, with especial reference to determining the presence of a nervous system in them and its extent and functions. The author at first intend- ed to supplement the accounts of his own work with an exposition of the results which had been obtained by other inquir- ers, concerning the morphology and devel- opment of those animals. He found, how- ever, that he would not be able, within the limits of the contemplated book, to do jus- tice to the labors of others, and has con- fined himself to giving an account of his own researches. The nervous systems of these animals, as studied by Professor Ro- manes, are mainly subservient to the office of locomotion, the plan or mechanism of which is completely different in the two classes, and unique in each. The investiga- tions of which this treatise is the result were carried on through six summers spent at the sea-side out of the vacations of twelve years, and were profitable and edi- fying in more ways than one. On this point, the author makes some remarks which form a fitting introduction to the story of hia detailed and technical experiments. "Speaking for myself," he says, "I can testify that my admiration of the extreme beauty of these animals has been greatly enhanced — or, rather, I should say that this extreme beauty has been, so to speak, re- vealed— by the continuous and close ob- servation which many of my experiments required ; both with the unassisted eye and with the microscope numberless points of detail, unnoticed before, became familiar to the mind ; the forms as a whole were impressed upon the memory ; and, by con- stantly watching their movements and changes of appearance, I have grown, like an artist studying a face or a landscape, to appreciate a fullness of beauty the esse of which is only rendered possible by the percipi of such attention as is demanded by scientific research. Moreover, associa- tion, if not the sole creator, is at least a most important factor of the beautiful ; and, therefore, the sight of one of these animals is now much more to me, in the respects in which we arc considering, than it can be to any one in whose memory it is not connected with many days of that purest form of enjoyment which can only be experienced in the pursuit of science. And here I may observe that the worker in marine zoology has one great advantage over his other scientific brethren. Apart LITERARY NOTICES. 273 from the intrinsic beauty of most of the creatures with which he has to deal, all the accompaniments of his work are aesthetic, and removed from those more or less of- fensive features which are so often neces- sarily incidental to the study of anatomy and physiology in the higher animals." This book is Volume XLIX of the " Inter- national Scientific Series." Geology and the Deluge. By the Duke of Argyll. Glasgow : Wilson & Mc- Cormick. Pp. 47. This is the substance of a lecture deliv- ered in Glasgow, in which is considered the question whether any scientific evidence exists that there has occurred a deluge, or a great submergence of the land under the sea over a considerable area of the globe ; of a temporary character; accompanied with the destruction of animal life ; since the birth or development of man ; in oth- er words, corresponding with the flood de- scribed in the Bible. The author finds evi- dence of such a flood, not only in universal tradition, but also in many superficial geo- logical facts ; among them, the existence of beds of recent marine gravel on mountain- tops in Wales and other countries ; the loess, with its abundant land-shells ; the extinct mammalian fauna of Europe, of the sudden destruction of which he adduces many evidences ; and the masses of mam- moths in New Siberia. The evidences of the contemporaneousness of man with the phenomena are discussed, and the question of his antiquity incidentally. The time of the flood in question is believed by the author to have been about the close of the glacial period. The Rescue of Greelt. By Commander W. S. Schley, U. S. Navy, and Profes- sor J. R. Soley, U. S. Navy. New York: Charles Scribner's Sons. Pp. 2*7*7, with Illustrations and Maps. Price, $3. This book gives a plain account of the Greely expedition, of the attempts that failed to relieve it, and of the one that final- ly succeeded. It has been the aim of the writers to describe the events simply as they occurred, and avoid all criticism of the pe-rsons who took part in them. This they have done, in the colorless manner in which vol. xxvii. — 18 all stories ought to be told on which the world is to be called upon to pass an im- partial judgment. The relation is begun with a general description of the region in which the search was prosecuted, as " the gateway of the Polar Sea," and an account of the circumpolar stations which were established under the auspices of the In- ternational Polar Conference, with which Greely's expedition eventually became con- nected. Then are given accounts of Gree- ly's Lady Franklin Bay expedition and the unsuccessful relief expeditions of 18S2 and 1884, and the detailed account of the ex- pedition under Commander Schley which succeeded in bringing back the survivors of Greely's command. Of the spirit in which the last expedition was prosecuted, the author of the book says that all of the officers and men " knew that the object of the voyage was something above and be- yond the ordinary calls of service, and . . . felt an earnestness of purpose which a mere exploring expedition would hardly have called forth. At any rate, whatever may have been their feelings, they certainly evinced a determination to spare no pains, to incur any exposure, to assume any re- quired risk, and to be unflagging in watch- ing for opportunities to gain a mile, a yard, or a foot, on the journey toward Greely and his party." In the Lena Delta. A Narrative of the Search for Lieutenant -Commander De Long and his Companions, followed by an Account of the Greely Relief Expedi- tion. By George W. Melville. Edited by Melville Philips. Boston : Hough- ton, Mifflin & Co. Pp. 497, with Maps and Illustrations. Price, $2.50. Op the world's heroes, the men of the Jeannette Expedition were certainly among the noblest, the sturdiest, and the most en- during. Whether we regard the single in- cident of the attitude in which Lieutenant De Long's body was found, with the arm frozen stiff in the position in which it was raised and bent to cast his journal to a safer place ; or wl ether we consider the trials and sufferings and pluck of Melville's party, of eleven men, during their trying and lonely journey — we can almost, and when we take note, as well as of these incidents, of the history of the expedition as a whole, we can 7+ THE POPULAR SCIENCE MONTHLY. quite say with Mr. Philips, that " in all the world's history the story has no parallel." This story has already been told by differ- ent persons from different points of view ; but by none who had a better right to tell it and from whom the world had a better right to ask for it than Engineer Melville, who after De Long's death was the titular commander of the expedition. The earlier part of the expedition, up to the crushing of the Jeannette by the ice, being already famil- iar, is but lightly dwelt upon. The real inter- est begins when the men took to the ice, and increases till the end of the search for De Long's party. The book abounds with inci- dents that help to realize what Arctic life really is. The constant imminence of its dangers was shown when the floe on which the party were encamped split through the center of De Long's tent ; " and had it not been for the weight of the sleepers on either end of the rubber blanket those in the mid- dle must inevitably have dropped into the sea." A strong picture of the straits to which men may be reduced for food ap- pears in the observation that walrus -hide may have the solitary advantage over hemp for ropes, in that " upon a pinch it can be eaten. Indeed, fresh walrus -hide, roasted with the hair on, is toothsome at any time, and many members of our company feasted on it after consuming their rations of pem- mican.'" We have views of what traveling on the ice is when we are told that the men did not mind having their toes protruding through their moccasins so long as the soles of their feet were clear of the ice, but they could not keep them clear ; and in the inci- dent of their finding — having, in order to keep all their things together, to go thirteen times over each mile — that, after marching from twenty-five to thirty miles a day for two weeks, they had been drifted back twenty-four miles. Finally, at the begin- ning of winter, on the 6th of August, they were able and glad to take to the sea, in three boats. They kept together till some time after the 10th of September, when they were separated in a furious storm, and one of the boats was never afterward heard from. It was agreed they should all en- deavor to land at Cape Barkin, and meet there. How they landed, and what befell either of the two parties that survived the sea-voyage, are graphically told by Engineer Melville, from his own experiences and from the narratives of Nindcman and Noros and the notes left by Captain De Long. The account of the Greely Relief Expe- dition is brief, but testifies to the value of Greely's work — that there is no one living competent to criticise his conduct of the expe- dition on which he was sent, " beyond affirm- ing that he performed the greatest amount of scientific work possible at least expense, and made good his retreat from depot to depot, until he arrived at the point of safety, where our Government had promised to de- posit supplies and have a vessel awaiting to carry him and his band away from the ' Land of Desolation.' " Not daunted by what he has seen and experienced of Arctic traveling, Mr. Melville has started again for the north pole, expecting to reach it, and to confirm a theory he has formed of the proper way of getting there. Believing that no vessel can penetrate the ice-barrier much beyond where explorers have gone, he fig- ures to himself a firm or nearly firm ice-cap interspersed with frequent islands, cover- ing the sea from the eighty-fifth parallel to the pole, and that a properly equipped ex- pedition can cross this and return upon it, the whole distance both ways being only a hundred miles greater than his party trav- ersed from the Jeannette to the Lena Delta ; and he believes that the results to accrue from reaching the pole will more than pay for all that has been spent in other efforts. MiND-READING AND BEYOND. By WlLLIAM A. Hovey. Boston : Lee k Shepard. Pp. 201. Price, $1.25. An association of gentlemen engaged in scientific investigation was formed in the spring of 18S2, under the designation of the Society for Psychical Research, the object of which was stated in its prospectus to be to examine the nature and extent of any in- fluence which may be exerted by one mind upon another, apart from any recognized mode of perception ; the study of hypnot- ism, mesmeric trance, clairvoyance, and al- lied phenomena ; a careful investigation of data regarding apparitions ; and an inquiry into the phenomena commonly called spir- itual. Among the members of this society were Lord Rayleigh, the Bishop of Carlisle, LITERARY NOTICES. 275 Professor Sidgwick, Professor Balfour Stew- art, William Crookes, and Alfred K. Wallace. They made a considerable number of ex- periments, in which phenomena were de- veloped that are not yet fully accounted for. From the reports on these experiments made by the several committees to whom the su- pervision of them was intrusted, Mr. Hovey has prepared the present interesting and sug- gestive volume. The Patriarchal Theory, based on the Papers of the late John Ferguson Mc- Lennan. Edited and completed by Don- ald McLennan. London: Macmillan & Co. Pp. 355. Price, $4. Mr. McLennan, in his book on " Primi- tive Marriage," and in an essay which he published about fifteen years ago, on " The Worship of Animals and Plants," propound- ed some original and striking views, and opened up new lines of inquiry into the ori- gins and conditions of primitive society. He was making the investigations of which these publications were the first fruits, his life-work, when his career was cut short, be- fore he was able to perfect anything further, by sickness and death ; but not till he had seen his views received respectfully, con- firmed in his own mind by new facts and circumstances, and made a part of the light under which the continued study of an- thropology would be conducted. It was his purpose, if health and strength had been given him, to undertake a general work on the structure of the earliest human socie- ties. " In particular," says his brother, " he felt that he was able to give a much more consistent and intelligible view of the con- dition of rude or undeveloped communities than anything that had previously been of- fered to the public." His research being of a very extensive and far-reaching kind, and involving the use of " a very large apparatus of evidence," he proposed " to prepare the way for his larger work by first issuing a critical essay, by which he hoped to clear out of the way a body of opinion, the prev- alence of which seemed to oppose an ob- stacle to the proper appreciation of his con- structive argument." This " body of opin- ion" was represented by the theory that the family living under the headship of the father was the ultimate social unit, which while it is very old, had recently taken its most important and influential shape in the works of Sir Henry Maine. This " critical essay" he had on hand, assisted by his brother, who now completes it, and had carried out to seven of the nineteen chap- ters of the present volume, with notes em- bodying his views as to other parts of the work, when he died. The work is neces- sarily, by the circumstances of the case, somewhat polemical in form, but not wholly so, for the latter part of it is largely de- voted to the buildng up of a theory of the origin of agnation, in the course of which it became necessary to go into the whole question of the Levirate and of the family custom of the Hindoos. " It has appeared at all points," says the editor, " not only that the phenomena dealt with are not intelligi- ble on the patriarchal theory, but that they carry us back to a stage of society prior to the form of the family which has a father at its head, to the stage of polyandry, and to the form of the family founded upon kin- ship through women only. The argument has been throughout constructive as well as critical, and no slight part of the work is purely constructive." Cnited States Commission of Fish and Fish- eries. Report of the Commissioner for 1882. Washington : Government Print- ing-Office. Pp. 1,101, with Plates. The commission having completed the tenth year of its work, the report takes general notice of what it has accomplished. It was formed primarily to investigate the alleged decrease of food-fishes in the United States, but had added to its duties in its second year that of promoting the propaga- tion of fish. It has accomplished much for science by prosecuting, or aiding others to prosecute, researches into the general natu- ral history of marine animals and plants. It has made very large collections of aquatic animals in aid of monographic research, and has given a full series to the National Museum, and sets to several hundred insti- tutions of learning, etc. During 1882 it secured a permanent sea-coast station at Wood's Holl; fitted up the Armory Build- ing as its central Washington station ; ac- quired stations in Maryland and Virginia ; furthered the artificial production of oysters, and the production and distribution of the carp ; and made inquiries into the extensive 276 THE POPULAR SCIENCE MONTHLY. destruction of the tile-fish in the North At- lantic. For the future it hopes to extend its general inquiries ; to promote improve- ment in methods and apparatus of fishing, and in fishing-vessels ; to determine the ex- tent and general character of the old fishing localities and discover new ones ; to improve methods of curing and packing fish for the market ; and to continue the work of in- creasing the supply of valuable fishes in the waters of the United States. Report of the Operations of the United States Life-Saving Service for the Year ending June 30, 1883. Washington: Government Printing- Office. Pp. 519. One hundred and ninety-four stations were maintained at the close of the year covered by the report— one hundred and forty-nine on the Atlantic, thirty-seven on the lakes, seven on the Pacific, and one at the Falls of the Ohio. The number of disasters to documented vessels and small boats was 416, in which $7,242,729 of prop- erty and 4,040 persons were involved, while $5,671,700 of the property and 4,021 per- sons were saved, and 651 shipwrecked per- sons were succored at the stations. Twenty- two other persons were rescued who had fallen from wharves, piers, etc. Ten dis- asters, involving the loss of lives, took place within the scope of the service. All of the nineteen persons lost were entirely beyond human aid. Researches on Solar Heat and its Absorp- tion dy the Earth's Atmosphere. By S. P. Langley. Washington: Govern- ment Printing - Office. Pp. 242, with Plates. Professor Langley's observations are already quite well known to the scientific world, and their value is universally acknowl- edged. They were made on the slopes of Mount Whitney, at a height of twelve thou- sand feet above the sea, and about three thou- sand feet below the summit of the mountain, with special instruments of the observer's own devising. Notices of some of the re- sults have been given in the " Monthly." The author expresses the opinion that Mount Whitney is an excellent station for such ob- servations, fully equal to any that is pos- sessed by any other nation ; and, upon his recommendation, it has been declared a Gov- ernment reservation, available for purposes of scientific research. Professor Langley records some very interesting facts respect- ing a dust-cloud which appears to hang in the Sierras at a certain height above the sea, the effects of which he was able to ob- serve from his camp, and which appears to be permanent. Professor Clarence King as- cribes its origin to the loess of China. The author also speaks of large logs, which were found to be quite numerous on the mount- ain-side at a considerable height above the timber-line, as indicating that the region formerly enjoyed a warmer climate than it now has. The relation of the observations which formed the object of the expedition is very important and interesting to men of science, but too technical for the edification of general readers. The Stars and Constellations. By Royal Hill. New York : Funk & Wagnalls. Pp. 32. This work is intended to enable students and others, who are interested in the ap- pearance of the heavens, to identify the principal objects of interest without refer- ence to star-maps, which as a general thing are very perplexing to unprofessional read- ers. The plan adopted by the author is new, and constitutes the main feature of the work. It consists in the employment of two accurately drawn time-charts, giving the exact time of rising and southing for every day in the year, of twenty-five of the brightest stars, which are more distinctly identified in the text. From the positions of these " landmarks of the sky," any oth- er object at all likely to attract the atten- tion of naked-eye observers is so described that it is very difficult for any person of or- dinary intelligence to miss the information desired. As each object is identified, the student can learn whatever is of interest concerning it by consulting the separate account that is given of every conspicuous star and constellation visible in this country. The subject is suitably introduced by some interesting information concerning the con- stellations, the names and numbers of the stars, and the methods adopted by astrono- mers to designate them. It is illustrated by several very clear maps of the zodiacal constellations, upon which the place of the LITERARY NOTICES. 277 sun for every day in the year is accurately marked. These maps, which show every star in these constellations to the fifth mag- nitude, we understand are the first ever published based on the admirable photo- metric observations of Professor Pickering, the Director of Harvard Observatory. We regard the idea on which the plan is based as a sound one, and the execution of the work as conformed to it. The arrangement is simple, and the directions, in the table, in the charts, and in the text, are clear and accurate. The " Quincy Methods " illustrated. Pen- Photographs from the Quincy Schools. By Lelia E. Partridge, New York : E. L. Kellogg & Co. Pp. 660. Price, $1.50. The educational world was startled a few years ago by the report of the great things that were going on in the schools of Quincy, Massachusetts. A new superintendent had been placed over them — Colonel Francis W. Parker — who had dared to break through the shell of formalism and routine within which they were being fossilized, and to infuse into them life, spontaneity, and real progress. The fame of the schools and of the new sys- tem— which was not new, however, to many, but too few, teachers of rare genius for their work — spread widely, and Quincy became a place of frequent resort for persons having at heart the interests of real instruction. Among those who went there was Miss Partridge, who recorded what she saw, and now publishes her record. She takes the reader into the school-room and its different classes, day after day, and exhibits, in her printed account, a transcript, exact as it may be, of what occurred there — illustrating how the teacher started, now this subject, now that, and patiently, and with tact, drew out whatever suggested itself to each of the pupils upon it. As the lessons are advanced, they shape themselves into a kind of sys- tem, the operation of which is to awaken the minds of the pupils to self-action and independent thinking. The manner in which these accounts are rendered justifies the secondary title of " Pen-Photographs" which the book bears. The author is careful to remind her fellow-teachers that the example- lessons she gives are not to be copied from but are to serve as types, after which teach- ers must form their own methods according to the bent of their minds and the kind of children they have in charge. The essential features of the Quincy method are flexibili- ty and spontaneity. What is called by that name might, in the hands of a humdrum teacher, become as dead and worthless as any of the stereotyped forms it is intended to supplant. It is its spirit that must be caught, not any of its particular models fol- lowed ; and the success of its execution will depend most largely upon the power of the teacher to strike out a way of his own. Mortality Experience of the Connecticut Mutual Life Insurance Company, of Uartford, Connecticut, from 1846 to 1878. Hartford, Conn. Pp. 91. A series of thirty-seven tables, showing the mortality results of as many kinds of policies or classes of insured, accompanied by a text explaining the taole, and calling attention to the more important of the re- sults. The Vertebrata of the Tertiary Forma- tions of the West. By Edward D. Cope. Washington : Government Print- ing-Office. Pp. 1,009, with 135 Plates. This bulky quarto is " Book I " of the fourth volume of the final reports of the Haydcn Geological Survey. Its import in paleontological science is of much signifi- cance, for it contains a great number of species and genera of vertebrate animals from the fertile tertiary beds of the West, which had not been previously discovered. Some of these fill gaps in the chain of spe- cies, and make the connection and the course of development more plain than they were before. The whole collection represents a part only of the results of the researches which the author prosecuted either person- ally or with the aid of his trained assistants during the exploring seasons of 1872, 1873, 1S77, 1878, 1879, 1880 and 1881, and to a lesser extent in some of the intervening years not recorded in this list. The regions in which the explorations were conducted cover portions of the States and Territories included between British America on the north, the western boundaries of Minnesota and Missouri on the east, the northern bor- ders of the Indian Territory and Arizona and the middle of New Mexico on the south, 278 THE POPULAR SCIENCE MONTHLY. and the Sierra Nevada on the west. The present volume does not include all the re- sults of Professor Cope's researches, for another is to follow. Professor Hayden well says of the whole, in his letter trans- mitting the report, that " the amount of new matter toward the origin and history of the mammalian groups brought together by the author in these two volumes is most extraordinary, and will probably never be surpassed." In this single volume are given the vertebrata of the Eocene and of the Low- er Miocene, less the Ungulata, with descrip- tions of 349 species, which are referred to 1 25 genera. The author sums up fifteen im- portant results that have accrued through the researches here set forth in the discovery of new genera and families, among which are the discovery of the phylogenetic series of the Canida;, or dogs, and the same of the ancestors of the Fclidce, or cats. As the book was stereotyped in 1883, all conclu- sions of later date than that are necessarily excluded from it ; but the author's final conclusions from the material described are mostly to be found in a series of illus- trated articles he has been publishing in the " American Naturalist " in the years 1883-'85. The Ten Laws of Health ; or, IIow Dis- eases ARE PRODUCED AND PREVENTED. By J. R. Black, M. D. Published by the Author. Baltimore. Price (by subscrip- tion), $2.50. A part of this book was published sev- eral years ago. The edition having been exhausted for many years, the matter has been revised to bring it up even with the progress of the age, and an entirely new part has been added, comprising nearly a fourth of the present volume, on thorough disinfection within the sick-room and the sick-bed as the most effective means for pre- venting the spread of contagious diseases and epidemics. The author is a strong be- liever in the doctrine that disease is unneces- sary and preventable ; in his view man is the most sickly of beings, because those — which means most men — " who neither know nor strive to be governed by law in the uses they make of themselves, become victims to hundreds of evils in the various forms of disease." The ten laws of health are taken up in their order and explained ; the viola- tions of them are shown, with their attend- ant results ; and the mode of observing them is taught. The first law is, that a pure air must be breathed. To obtain this within the house, supposing that the surroundings arc pure, " the great and imperative require- ment is air-movement, a decided though gen- tle current through an occupied room day and night." Second ; the food and drink must be adequate and wholesome. The evil to be guarded against in the United States is excess, for inadequateness or a deficiency of food on this continent, although the com- mon sentiment is quite the reverse, is not often a direct cause of disease. As to the quality of our food, as we prepare it, " of the many books published on the subject of cooking, there are few, if any, that have not receipts by the score which can not be ex- celled for producing indigestion." The ef- fects of tea and coffee and alcoholic stimu- lants are carefully considered. The third law enforces the necessity and judicious practice of out door exercise ; and the fourth law prescribes adequate and unconstraining covering for the body. The fifth law con- cerns the exercise of the sexual function. Under the head of the sixth law are consid- ered the effects of changes of climate, and the measures to be taken for safe acclimati- zation when that step is taken. Regarding changes of climate for the sake of health, the author concludes, from a survey of the available facts on the subject, " that an im- prudent change of climate more frequently destroys the health of the healthy than it cures the sickness of the sickly." The sev- enth law relates to the choice of occupation. Its admonition is to select such pursuits as do not cramp and overstrain any part of the body, or subject it to irritating and poi- sonous substances ; and, of course, to avoid those of an opposite character. Next, we are to keep personally clean, bathing sys- tematically and changing regularly all cloth- in" next to the skin. " Those who for month after month, and even for year after year, do not cleanse and invigorate the skin by frequent baths, followed by brisk friction of the skin, lose the good offices of a very active organ of regeneration, and cause their blood to be in a state very favorable for the production of disease from slight causes." Ninthly, we must preserve the mind in a trail- LITERARY NOTICES. 279 quil state, and secure adequate rest and sleep. "For health, as well as happiness, moderation and diversity of pursuits arc essential requi- sites." Tenth and last law : " No inter- marriage of blood relations." The principle is kept in view and enforced by frequent repetition that violations of any of these laws work injury from the beginning, the evil increasing as the violations become ha- bitual, and that for years, perhaps, before the sinner perceives that anything of the kind is taking place ; even while he may be boastful of his strength and his superiority to the bad effects of his wrong-doing ; and that, when the injury is at last revealed, it is generally past remedy. The injunctions in the second part of the book, for preventing the spread of infectious diseases by stamping them out within the sick-room, are based on the germ theory of disease. The principles on which they are justified, concisely stated, are, that " persons sick of infectious diseases are the breed- ing hot-beds from which the germs issue; that these germs make of air, drinks, and foods, mediums by which they are carried into the bodies of others; and, that when they once pervade the air, mix with foods and drinks, they can neither be detected nor destroyed ; and, as a corollary, that the only time effectually to destroy them is at the bedside as they pass from the bodies of the sick." To wait, as is too often done, till they have escaped, expecting then by stern- er measures to stop the spread of disease, " is like waiting until a fire becomes an alarming conflagration before making systematic ef- forts to subdue it " — and " even far worse." The directions for enforcing this summary disinfection are plain and practical. Resultados del Observatorio Nacional Argentino en Cordoba. (Results of the Argentine National Observatory in Cordoba.) By Benjamin A. Gould, Di- rector. Vols. II, III, IV, VII, and VIII. Spanish and English. Buenos Ayres and Cordoba. Tp. (total) 2,243. We have already (March, 18S2) given a sketch of Professor Gould's life and astro- nomical work, both at home and in Cordoba, and a notice of the first publication of the results of his observations in the southern hemisphere, in the " Uranometria of the Southern Heavens." The present volumes embrace a part of the record of his work at Cordoba as it has been pursued, in consid- erable but not complete detail. At the beginning, the author entertained the hope of being able to publish all the observa- tions in essentially the same form as they had been made, affixing the instrumental corrections separately. The observations of the years lS72-'73 were prepared for the press in this form, but the im possibility of carrying out the plan became manifest as the number of results increased ; and at last anxiety arose lest it might not be possible to secure a prompt publication of the results in any shape whatsoever. The observations for the catalogue have there- fore been given in the compact form adapt- ed to the requirements of the case ; and those of the zones with only so much de- tail as seemed needful when a large propor- tion of the stars had been observed but once. The original observations and all the calculations have been preserved for reference. The zones which have been sur- veyed in these observations cover a breadth of 52' 20' in declination, extending from 23° to 80° south. Previous determinations of position by zone-observations have been essentially differential in their character, in one co-ordinate, at least, when not in both ; in the present undertaking, Dr. Gould has endeavored to obtain so-called absolute de- terminations for all the stars observed. During the eight and a half years of work up to the close of 1880, more than 250,000 stellar observations were made with the meridian-circle ; and the number of differ- ent stars observed is estimated at 35,000 — all belonging to the southern hemisphere. Among the special observations was a care- ful determination, of positions and proper motion, of fifty-four circumpolar stars for determination of the azimuthal errors of the instrument. Vol. II of the present scries contains the observations made in 1872; Vols. Ill and IV, those made in 1873; and Vols. VII and VIII, the zone-observations made in 1875. In making these observa- tions, between declinations 23° and 47°, the normal width of the zone was two degrees, with 10' additional at each margin and extremity for overlap ; from 47° to 75°, their width increased with the declination ; until, finally, the last five degrees, 75° to 28o THE POPULAR SCIENCE MONTHLY. 80°, were comprised in a single belt. The zones were also subdivided, where that seemed best. The Distribution of Products, or the Mechanism and Metaphysics oe Ex- change. By Edward Atkinson. New York : G. P. Putnam's Sons. Pp. 303. Price, $1.25. Mr. Atkinson, a man of business, has spoken so often, so intelligently, and so much to the purpose on financial questions as to give him a right to be heard and weight to his views. The present volume includes three essays — on " What makes the Rate of Wages ? " " What is a Bank ? " and " The Railway, the Farmer, and the Public." The subject of the first essay is attended with a complication of conditions and relations, and differences of opinion upon it are in- evitable. Mr. Atkinson takes an optimistic view of the prospects of a satisfactory set- tlement of the relations of capital and la- bor on the conditions set forth in his funda- mental proposition. He shows that a high rate of wages does not necessarily signify high cost of production, and vice versa, and enforces a distinction, too often overlooked, between rate of wages and sum of wages in the manufacture of a given product. The second essay presents an exposition of the principles on which safe banking is con- ducted. In the third essay the author shows that the railways have performed a great service in our national economy, and that a large reduction in the costs of transporta- tion has been brought about by the consoli- dation of the principal lines ; and maintains that nearly all the features of our present railway system are working, as a whole, for good. Paradise Found: A Study of the Prehis- toric World. By William F. Warren, LL. D. Boston : Houghton, Mifflin & Co. Pp. 505. Price, $2. The Count de Saporta, Mr. G. Hilton Scribner, and others, have made our readers familiar with the hypothesis that the cradle of the human race and of all life must be sought at the north pole. The accession of so many men known to be careful ob- servers, imbued with the scientific spirit, and habituated not to express an opinion unless they have reason- nt hand with which to fortify it, as have uttered views consist- ent with this hypothesis, has lifted it up out of the category of speculations to a genuine theory, claiming deliberate investi- gation. Dr. Warren, who is President of Boston University, has arrived at conclu- sions nearly coincident with those of Count de Saporta and those who agree with him, through his own independent studies, though not, of course, without having them re- enforced by theirs. In the present work, he offers the considerations by which the theory of polar origin is to be supported, carefully worked out, and in their order. Beginning with a survey of the present state of the question of the location of Eden and of the existing theories upon it, he presents in Part Second his own hypothesis, with a definition of the conditions on which it may be admissible ; in Part Third, the scientific bearing on it of gcogony, geography, geol- ogy, prehistoric climatology, paleontologi- cal botany, zoology, and archaeology and general ethnology; in Part Fourth, confir- mations of the hypothesis by ethnic tradi- tion— from ancient cosmology and mythical geography, and from Japanese, Chinese, East Aryan, Iranian, Akkadian, Assyrian and Babylonian, ancient Egyptian and An- cient Greek thought ; in Part Fifth, fur- ther verifications of the hypothesis, based upon a study of the peculiarities of a polar paradise ; and in Part Sixth, the significance of the results he has drawn from these con- siderations.

Schools of Fifty Years ago and of To- Day. — The Rev. Edward Everett Hale, in a re- cent article on " Half-Time Schools," assert- ed, among other things, that, on the whole, schools and school-teachers were better fifty years ago, when they turned out an occa- sional Daniel Webster, than they are now ; that all schools are " revolting " to pupils ; that the average boy, who has many weeks of vacation per year, is likely to learn the value of time, the necessity of punctuality, and the need of subordination, and to ac- quire modesty and self-control, order and method, quite as well as he does at school ; that the old idea of school, as a place for study in reading, writing, and arithmetic, is the correct one, and all else is to be taught and learned somewhere else ; and that such practical affairs as a knowledge of things, tools, and the processes of handicrafts, can not be successfully taught at school, but are learned more quickly and better at home or at work. Professor Woodward, of Washing- ton University, St. Louis, has answered some of Mr. Hale's points. He quotes, from an article of his own, the evidence that the boys in his manual training-school enjoy their school hours with real zest, and re- marks on what schools of to-day should teach, as contrasted with the schools of Dan- iel Webster's day : " When Daniel Webster was a boy, there was not a railroad, nor a telephone, not even a telegraph nor a steam- boat, in the land. Our present methods of supplying cities with food, with fuel, with shelter, with clothing, were unknown. There was not an armored ship, nor a breech-load- ing gun, nor a dynamo, in the world, and one half of the present occupations of men did not exist. Are our schools to be con- ducted in blissful ignorance of all this?" He adds : " I do not say that schools should teach trades, any more than that they should teach banking, or piano-playing, or teleg- raphy. They should only teach principles, and methods, and the use of tools and appli- ances applicable to a majority of the occu- pations of American civilization; these they should teach for three reasons : 1. Opening the way to an intelligent choice of occupa- tion ; 2. Insuring success in the chosen oc- cupation ; and, 3. Raising the intellectual and moral standards of manual occupations. It is scarcely necessary to add that three hours per day given to manual training (drawing and tool-work) leave abundant opportunity for literary and scientific train- ing, or that the intellectual development of pupils thus broadly exercised is both whole- some and rapid." The Medico-Legal Society. — Mr. Clark Bell, in his address on retiring from the presidency of the Medico-Lf gal ^ociety,points to the high character of the membership of the body as entitling it to that respect and confidence which arc now awarded it by stu- dents of medical jurisprudence throughout the civilized world. It has three hundred and ninety-four members. Its library has largely increased, by the gift of books from members and honorary and corresponding members, and is now said to be the best sin- gle collection of works on medical jurispru- prudence in this count iy outside of that em- braced in the library of the Surgeon-Gener- al's office in Washington. Its list of honor- ary and corresponding members embraces gentlemen of the highest distinction and emi- nence in the science of medical jurispru- dence, in America and Europe. The con- stitution of the socicly has been enlarged so as to admit to active membership persons throughout the United States and Canada. The " Medico-Legal Journal " has a circula- tion of two thousand copies.

Cardinal Pitri on Scientific Studies. — Cardinal Pitri, a prelate enjoying high dig- nities at the papal court, has appeared as a contributor to the Roman scientific jour- nal " Cosmos " of an article, advising the clergy to cultivate science. "It is a good thing," he says, "for those who have in theology the key to all the sciences, not to neglect any of them. We, too, ought to have our specialists who understand and help us to understand the views of men of learning, and are prepared to meet them on their own ground. While they cherish the science of the sanctuary, the clergy should also be familiar with secular knowledge." Not only this, but " ecclesiastics and mem- bers of religious orders, especially those addicted to tradition, should be found among the men of bold speculation and re- search ; for tradition is no less necessary for science than for faith." The cardinal recommends those studies, although they at first sight look dry, as sure to afford "a pure and healthy delight, which grows into enthusiasm in proportion as they are per- severingly cultivated." It must be remem- bered, he adds, that such studies only tend further to establish " those fundamental verities whence flows more or less directly the explanation of whatever can be ex- plained." For the material universe is " a sealed book " to those who acknowledge no Divine Crea:or and Upholder of the wonder- ful forces which surround us on every side. But it behooves the young clergy to be care- ful against coming to too hasty conclusions in their endeavors to harmonize theology and science. " It is neither prudent nor safe to adopt scientific hypotheses too quick- ly into the domain of theology and her- mencutics." The observation is enforced by incidents in his own experience, that wo have had " modern theologians retreating from explanation to explanation, embar- rassed between the periods of the anterior creation " : and, while the texts that have given occasion to controversy are " equally inspired with the rest of Scripture," it is " dangerous to apply them unreservedly to each passing system " ; and is much more prudent " not to be in a hurry to make a theological thesis of a learned hypothesis and commit one's self to it, when no such obligation is imposed on us by the constant teaching or defined dogmas of the Church." The Soil-Ferment. — It was determined by experiment, a few years ago, that the capacity of earth to purify sewage from organic matters by oxidation could be sus- pended by treating the earth with chloro- form, but that in time the soil would regain its oxidizing quality. The conclusion was reached from this observation, that the oxidation of organic matters ia sewage de- pends, in part at least, on the presence of small living organisms whose activity could be suspended by dosing them with chloro- form. This conclusion has been confirmed by subsequent observations, and it is be- lieved now that the oxidizing property of the soil is promoted by the presence of a micrococcus, which acts most efficiently at a temperature about that of the blood, but more feebly at higher or lower temper- atures, while its efficiency ceases entirely at near the freezing-point and above 130° Fahr. It appears to bo, in dry soils, most abundant in the upper six inches, and to cease to act at depths below eighteen inches. It has been further determined by these ex- periments that nitrogenous solutions to be acted upon by the ferment must be alkaline, while acid solutions are not affected. Ordi- nary house sewage is slightly alkaline and readily acted upon, but this susceptibility is destroyed when acid-manufacturers' wastes are admitted to be mixed with it, or with the soil. Evolution of Warlike and of Peaceful Races.— The "Pall Mall Gazette" finds in the doctrines of hereditability and modifi- ability reasons for supposing that the pres- ent Continental organizations of military life may ultimately result, by the weeding out of the warlike, in the development of a more peaceful and industrious race of men. 284 THE POPULAR SCIENCE MONTHLY. The cloister-life of the middle ages tended to the increase of the warriors by drawing gentle spirits and those skilled in the handi- crafts to the convents, and leaving it to the knights and their retinues to do the marry- ing and the bringing up of posterity. Now the military establishments of the European empires are working in the opposite direc- tion. They tend to draw the brave and the turbulent from married life, and to leave the raising of families to the industrious and those who shun the field of battle. The effect of the system on the population of France after the Napoleonic wars was visi- ble, and has been much remarked upon. Hence it is probable that the warlike na- tions are destined to decline, and peaceful ones, like Great Britain and the United States, to prevail, and thus will come to pass the prediction in the Sermon on the Mount, that the meek shall inherit the earth. The Mole a Fri?nil to Man. — A writer in " Land and Water " pleads for the mole as a much-abused animal which really does more good than harm, fulfilling its mission " of ventilating the soil with many-branched tunnels, and of converting insects, worms, etc., into fertile mold. . . . The ingenuity which the mole exhibits in the formation of his covered ways might stimulate — perhaps has done so — agriculturists to improve their drainage systems ; the comminuted earth and other material which he leaves behind him mijrht also instigate them to produce the same results on a scale commensurate with their requirements. . . . We cease to be surprised at the work executed by the mole when we examine its structure. The fore-paws, short and very sturdy, are moved by immense muscles, and are supported by a clavicle of great strength ; the broad palms arc turned outward, the better to form scoops for throwing earth, gravel, soil, etc., behind while the animal is burrowing. The ' fingers ' are small, so much so, in fact, as easily to be overlooked, but each is ter- minated by a nail, long, flat, sharp-edged, and very strong, eminently calculated as a tool for cutting through the soil. The snout, which we have noticed as furnished with a terminal bone, ae to be free from an exhortation to nourish ourselves, when desirous only to allay thirst or moisten our solid morsels with a draught of fluid. Not so ; there are even some persons who must wash down their ample slices of roast beef with draughts of new milk ! — an unwisely devised combination even for those of active habit, but for men and women whose lives are little occupied by exercise it is one of the greatest dietary blunders which can be perpetrated. 334 THE POPULAR SCIENCE MONTHLY. One would think it was generally known that milk is a peculiarly nutritive fluid, adapted for the fast-growing and fattening young mammal — admirable for such, for our small children, also serviceable to those whose muscular exertion is great, and, when it agrees with the stomach, to those who can not take meat. For us who have long ago achieved our full growth, and can thrive on solid fare, it is alto- gether superfluous and mostly mischievous as a drink. — Nineteenth Century. [To be continued,] AN EXPEKIENCE WITH OPIUM. By S. T. MOETON. THE subject of the " opium-habit " is one that recurs with ominous frequency in public print. Whenever touched upon, the inten- sity of interest elicited in the minds of certain readers (alas ! how large a number) would be incomprehensible to one not drawn person- ally to it. That the literature of this subject is mainly very discour- aging and unhelpful to this class is perhaps not the fault of its authors ; but such is uniformly the case. Of innumerable articles in periodicals and books by the dozen which I have read, it must be said that, while the evils of the "habit" ai'e pictured in burning lines, when the dis- cussion of treatment is reached, the habitue is left to believe that, in his case, if it be not impossible of cure, an attempt at total abandon- ment— with whatever medical skill he could command — would be at- tended with such hazards, and would inflict such tortures, mental and physical, as would be beyond the average power of endurance. Unquestionably but a small portion of the general public — of those, too, who know something of its blighting evils — have any adequate idea of the strength of this " habit," and of the great diffi- culty, or impossibility, in most cases, of unaided cure. The chief re- sponsibility, indeed, with the habitue lies in his initiation rather than in his continuance of the " habit." He can not, like the user of alco- hol or tobacco, by a strong effort of the will shake off his chains. A pathetic story has lately come to my knowledge of a young man, an under-graduate in an Eastern college, who had become a victim of the hypodermic use of morphia. He went with his father, who was engaged in the lumbering interest, into the primeval forests of Maine, hoping that during a stay of months with the wood-choppers he would be able to fight out the battle of gradual abandonment successfully. Through a strange fatality, when the party had just arrived at their camping-place, and were transporting their goods across a stream, the case of morphia was broken by an apparent accident and its contents AN EXPERIENCE WITH OPIUM. 335 scattered into the water. None but the haggard young man could, at the moment, comprehend the appalling magnitude of the calamity — there, as he was, two hundred miles from the nearest settlement ! He survived the terrible ordeal, but no words could express, he has said, the tortures and agony through which he passed during the suc- ceeding weeks. He was closely watched, else, at times, he would have drowned himself or have beaten his brains out upon the rocks. Months afterward he came back to the world a skeleton, worn and haggard, from his terrible contest. It was an experience to which he could never afterward refer without the most painful emotions. Not the least significant point in this veritable account is the fact that the young man always believed that his father had purposely brought about the catastrophe for the sake of bringing matters to a speedy end ! Has the usual treatment of the disease by physicians at this day anything to offer that is much better than this man's sum- mary method? Perhaps no work on the subject has appeared in recent years more careful and thorough in its scientific intention than Dr. Levinstein's "Morbid Craving for Morphia." It is evident that he has brought no common accuracy of observation to bear upon the subject. His clinical notes on a considerable number of cases of the disease treated by him are of absorbing interest to the morphia habitue. There is a striking parallel between the method of the Maine lum- berman I have described and that of advanced German science in the treatment of this disease. In both cases the patient suffers from the intense cruelty of ignorance ! The best thing to do for the unfortu- nate victim of morphia, according to this learned work, is to secure him in rooms under charge of a competent keeper or nurse, his person and baggage having been searched, and from the rooms " all opportu- nities for attempting suicide having been removed. Doors and win- dows must not move on hinges, but on pivots ; must have neither handles, nor bolts, nor keys ; being so constructed that the patients can neither open nor shut them. Hooks for looking-glasses, for clothes, and curtains, must be removed." Certainly these are ominous preliminaries to a course of scientific medical treatment ! Within this prison the patient is totally deprived at once of morphia in every form, and here he must struggle through the terrible weeks succeed- ing as best he may. So far as appears, he has but the slightest medical aid. His symptoms are closely watched, however, for the portentous shadow of one special danger looms ever near his bedside — that of a sudden collapse of his vital powers. A few moments' delay in such a contingency may prevent all power of resuscitation ; in any case, the situation is very critical. Fortunate will it be if morphia, which is always the immediate resort in such emergencies, have not lost its potency ! I will not recount the story of the tortures through which the 336 THE POPULAR SCIENCE MONTHLY. patient passes — the days and nights of writhing, the sleeplessness, the restlessness, the thirst, and endless vomitings and purgings ; his vain pleadings for liberty, for morphia, for anything which will re- lieve the intolerable anguish ! These clinical notes of Levinstein's, in form cold and terse as a hardware catalogue, are fairly burning with their burden of tragedy. But this treatment he offers as the best known, and its attendant sufferings he evidently believes are inevi- table in any cure ! It has happened to me to know, through personal experience, that the unfortunate victim of this " habit " can be freed from his bondage without passing through such an ordeal. I had been an habitue ten years, having reached at the end of that period the daily amount of thirty-six grains of gum-opium, taken only into the stomach. The "habit" had been begun by a very small amount, and its increase had been extremely gradual. I knew not where to turn for help in effecting a cure : one thing seemed certain, it could not be done without help. At a venture merely, I called upon the late Dr. George M. Beard, feeling that, at any rate, I should be free from the risk of charlatanism ; and I shall always remember him with gratitude, for it was through his recommendation that I placed myself under the care of another physician, who immediately undertook the treatment of my case. The gentleman whom, through the good fortune of Dr. Beard's introduction, I thus came to know, I found to be a young man in the prime of good health and spirits, and one who at once inspired me with that confidence so important in such a case. His residence, it was manifest, was no ordinary "institute" or "asylum." I was sim- ply a courteously received guest in a private family. Here were two bright children quietly pursuing their games when I first entered ; and I was soon introduced to a pleasant circle embracing the cultivated ladies of the doctor's family, as well as the three who were to under- take the new path simultaneously with myself. Among these good fellows, as I soon found them to be, I was a simple layman in a medi- cal " ring " as it were, for my comrades were young physicians, each under the hypodermic spell, doctors though they were, helpless like myself in the well-riveted chains. In this situation it is in no wise easy to follow the injunction, "Physician, heal thyself." Placed in these easy and pleasant relations, with every comfort, and — a most important material consideration— an appetizing table, everything outward was calculated to inspire a feeling of freedom and cheerfulness. I speak particularly of these favorable surroundings, for they seem to me to form a very important accessory of the treat- ment. This treatment differed in important respects from preconceived ideas, such as are fostered by almost everything written upon the sub- ject. The patient here, for instance, was under no surveillance and AN EXPERIENCE WITH OPIUM. 337 restraint. So far from being a prisoner, he was encouraged in taking walks and drives alone, or, with his fellow-patients, in attending even- ing amusements, etc. It was the doctor's theory that a person of any sensitiveness of nature could not rest under constant suspicion with- out a sense of resentment which would be prejudicial to the cordial relation which should always exist between physician and patient. "I ask for and extend confidence," he said, "and believe I largely en- hance a good result in so doing. Nor do I share in the opinion, largely held, that no reliance is to be placed upon the word of the opium habitue." Though he was well aware that this morbid habit in many cases exerts a baneful influence on the moral character, it is manifest that — were the doctor's theory of his patient's reliability and truthful- ness altogether erroneous — any plan of treatment based upon it would be entirely impracticable, however agreeable to the patients this view of their character. Within a week after the beginning of treatment my opiate was all withdrawn. What I had undergone at the end of that period, and, in- deed, for a day or two subsequent to the total discontinuance, could scarcely be called suffering ; it was rather a dull, heavy listlessness, as little painful as enjoyable. There was no mental or physical elasticity; exercise was not inviting — nor, indeed, was there the physical ability for it. It became impossible to read or even to think, except in an idle way. There was no pain or nervousness ; but principally a feel- ing of passive discomfort during this period, when the discontinuance of opium, unaided, would have brought on penal tortures. Thus " the Rubicon was crossed " — this being the exultant phrase with which the doctor greeted one after the other of our little band, as he passed over that hitherto impassable stream. But the few days succeeding the total deprivation were not so passive. Though I had landed on the other bank of that classic stream, the tu Mountain-ash Elder. Ash. Walnut. Ailantus.

Of course, however, these numbers are only approximate. Many things have to be taken into consideration. Strength, for instance is an important element. Thus the ailantus, with a stem equal in thickness to that of the horse-chestnut, carries a smaller area of leaves, perhaps because it is less compact. Again, the weight of the leaves is doubtless a factor in the case. Thus in some sprays of ash and elder which I examined of equal diameter, the former bore the larger expanse of leaves ; but not only is the stem of the elder less compact, but the elder-leaves, though not so large, were quite as heavy, if not indeed a little heavier. I was for some time puzzled by the fact that, while the terminal shoot of the spruce is somewhat thicker than that of the Scotch fir, the leaves are not much more than one third as long. May this not perhaps be due to the fact that they remain on more than twice as long, so that the total leaf area borne by the branch is greater, though the individual leaves are shorter? Again, it will be observed that the leaf area of the mountain-ash is small compared to the stem, and it may, perhaps, not be unreasonable to suggest that this may be connected with the habit of the tree to grow in bleak and exposed situations. The posi- tion of the leaves, the direction of the bough, and many other elements would have also to be taken into consideration, but still it seems clear that there is a correspondence between thickness of stem and size of leaf. This ratio, moreover, when taken in relation with the other conditions of the problem, has, as we shall see, a considerable bearing not only on the size, but on the form of the leaf also. The mountain-ash has been a great puzzle to me ; it is, of course, a true Pyrus, and is merely called ash from the resemblance of its leaves to those of the common ash. But the ordinary leaves of a pear are, as we all know, simple and ovate, or obovate. Why, then, should those of the mountain-ash be so entirely different ? May not, perhaps, some light be thrown on this by the arrangement of the leaves ? They are ON LEAVES. 347 situated some distance apart, and though, as shown in the table, they are small in comparison to the diameter of the stem, still they attain a size of fifteen square inches, or even more. Now, if they were of the same form as the ordinary pear-leaf, they would be about seven inches long by two to three in breadth. The mountain-ash, as we know, lives in mountainous and exposed localities, and such a leaf would be unsuit- able to withstand the force of the wind in such situations. From this point of view, the division into leaflets seems a manifest advantage. Perhaps it will be said that in some trees the leaves are much more uniform in size than in others. This is true. The sycamore, for in- stance, varies greatly ; in the specimen tabulated, the stem was *13 in diameter, and the area of the six upper leaves was sixty square inches. In another, the six upper leaves had an area of rather over one hundred inches, but in this case the diameter of the stem was *18. Another point is the length of the internode. In such trees as the beech, elm, hornbeam, etc., the distance from bud to bud varies com- paratively little, and bears a tolerably close relation to the size of the leaf. In the sycamore, maple, etc., on the contrary, the length varies greatly. Now, if, instead of looking merely at a single leaf, we consider the whole bough of any tree, we shall, I think, see the reason of their dif- ferences of form. Let us begin, for instance, with the common lime (Fig. 1). The leaf -stalks are arranged at an angle of about 40° with the branch, and the upper surfaces of the leaves are in the same plane with it. The Fig. i. Fig. 2. result is, that they are admirably adapted to secure the maximum of light and air. Let us take, for instance, the second or third leaf in Fig. 1. They are four and a half inches long and very nearly as broad. The distance between the two leaves on each side is also just four and a half inches, so that they exactly fill up the interval. In Tilia par- vifolia the arrangement is similar, but leaves and internodes are both less, the leaves, say, one and a half inch, and the internodes *6. 348 THE POPULAR SCIENCE MONTHLY. In the beech, the general plane of the leaves is again that of the branch (Fig. 2), but the leaves themselves are ovate in form, and smaller, being only from two to three inches in length. On the other hand, the distance between the internodes is also smaller, being, say, one and a quarter inch against something less than two inches. The diminution in length of the internode is not, indeed, exactly in propor- tion to that of the leaf, but, on the other hand, the leaf does not make so wide an angle with the stem. To this position is probably due the difference of form. The outline of the basal half of the leaf fits neatly to the branch, that of the upper half follows the edge of the leaf be- yond, and the form of the inner edge being thus determined decides the outer one also. In the nut ( Corylus), the internodes are longer and the leaves cor- respondingly broader. In the elm (Ulmns, Fig. 3), the ordinary branches have leaves resembling, though rather larger than, those of the beech ; but in vigorous shoots the internodes become longer and the leaves correspondingly broader and larger, so that they come nearly to resemble those of the nut. But it may be said the Spanish chestnut ( Castanea vulgaris, Fig. 4) also has alternate leaves in a plane parallel to that of the branch, and Fig. 3. Fio. 4. Fio. 5. with internodes of very nearly the same length as the beech. That is true ; but, on the other hand, the terminal branches of the Spanish chestnut are stouter in proportion. Thus, immediately below the sixth leaf, the chestnut-stalk may be '15 of an inch in thickness, that of the beech not much more than half as much. Consequently, the chestnut could, of course supposing the strength of the wood to be equal, bear a greater weight of leaf ; but, the width of the leaf being determined by the distance between the internodes, the leaf is, so to ON LEAVES. 349 say, compelled to draw itself out. In Fig. 5 I have endeavored to illustrate this by placing a spray of beech over one of Spanish chest- nut. Moreover, not only do the leaves on a single twig thus admirably fit in with one another, but they are also adapted to the ramification of the twigs themselves. Fig. 6 shows a bough of beech seen from above, and it w7ill be observed that the form of the leaves is such that, while but little space is lost, there is scarcely any overlapping. Each fits in perfectly with the rest. The leaves of the yew (Fig. 7) belong to a type very different from those which we have hitherto been considering. They are long, narrow, and arranged all round the stem, but spread right and left, Fia. 6. Fia. 7. Fig. 8> so that they lie in one plane, parallel to the direction of the branchlet, and their width bears just such a relation to their distance apart that when so spread out their edges almost touch. Fig. 8 represents a sprig of box. It wTill be observed that the increase of width in the leaves corresponds closely with the greater distance between the points of attachment. The leaves of the Scotch pine (JPinus sylvestris) are needle-like, one and a half inch in length and one twentieth in diameter. They are arranged in pairs, each pair inclosed at the base in a sheath. One inch of stem bears about fifteen pairs of leaves. Given this number of leaves in such a space, they must evidently be long and narrow. If I am asked why they are longer than those of the yew, I would suggest that the stem, being thicker, is able to support more weight. In confirmation of this, we may take for comparison the Weymouth pine, in which the leaves are much longer and the stalk thicker. When we pass from the species hitherto considered to the maples (Fig. 11), sycamores, and horse-chestnuts (Figs. 9 and 10), we come to a totally different type of arrangement. The leaves are placed at right 35° THE POPULAR SCIENCE MONTHLY. angles to the axis of the branch instead of being parallel to it, have long petioles, and palmate instead of pinnate veins. In this group the mode of growth is somewhat stiff ; the main shoots are perpendicular, and the lateral ones nearly at right angles to them. The buds, also, are comparatively few, and the internodes, consequently, at greater distances apart, sometimes as much as a foot, though the two or three at the end of a branch are often quite short. The general habit is shown in Figs. 9 and 10. Now, if we were to imagine six beech or Fig. 9. Fig. 10. elm leaves on these three internodes, it is obvious that the leaf surface would be far smaller than it is at present. Again, if we compare the thickness of an average sycamore-stem below the sixth leaf with that of a beech-stem, it is obvious that there would be a considerable waste of power. Once more, if the leaves were parallel to the branch, they would, as the branches are arranged, be less well disposed with reference to light and air. A glance at Figs. 9, 10, and 11, however, will show how beautifully the leaves are adapted to their changed conditions. The blades of the leaves of the upper pair form an angle with the leaf-stalks, so as to assume a horizontal position, or nearly so ; the leaf-stalks of the second pair decussate with those of the first, and are just so much longer as to bring up that pair nearly, or quite, to a level with the first ; the third pair decussate with the second, and are again brought up nearly to the same level, and immediately to the outside of the first pair. In well-grown shoots there is often a fourth pair on the outside of the second. If we look at such a cluster of leaves directly from in front, we shall see that they generally appear Fig. 11. ON LEAVES. 35i somewhat to overlap ; but it must be remembered that in temperate regions the sun is never vertical. Moreover, while alternate leaves are more convenient in such an arrangement as that of the beech, where there would be no room for a second leaf, it is more suitable in such cases as the sycamores and maples that the leaves should be opposite, because, if, other things remaining the same, the leaves of the sycamore were alternate, the sixth leaf would require an inconvenient length of petiole. Perhaps it will be said that the plane-tree, which has leaves so like a maple that one species of the latter genus is named after it {Acer platanoides), has, nevertheless, alternate leaves. In reality, however, I think this rather supports my argument, because the leaves of the plane, instead of being at right angles to the stem, lie more nearly parallel with it. Moreover, as any one can see, the leaves are not arranged so successfully with reference to exposure as those of the species we have hitherto been considering, perhaps because, living as it does in more southern localities, the economy of sunshine is less important than in more northern regions. The shoot of the horse-chestnut is even stouter than that of the sycamore, and has a diameter below the sixth leaf of no less than three tenths of an inch. With this increase of strength is, I think, con- nected the greater size of the leaves, which attain to as much as eight- een inches in diameter, and this greater size, again, has perhaps led to the dissection of the leaves into five or seven distinct segments, each of which has a form somewhat peculiar in itself, but which fits in admirably with the other leaflets. However this may be, we have in the horse-chestnut, as in the sycamores and maples, a beautiful dome of leaves, each standing free from the rest, and expanding to the fresh air and sunlight a surface of foliage in proportion to the stout, bold stem on which they are borne. Now, if we place the leaves of one tree on the branches of another, we shall at once see how unsuitable they would be. I do not speak of putting a small leaf such as that of a beech on a large-leaved tree such as the horse-chestnut ; but if we place, for instance, beech on lime, or vice versa, the contrast is sufficiently striking. The lime-leaves would overlap one another, while, on the other hand, the beech-leaves would leave considerable interspaces. Or let us in the same way transpose those of the Spanish chestnut ( Castanea) and those of Acer platanoides, a species of maple. I have taken specimens in which the six terminal leaves of a shoot of the two species occupy approximately the same area. Figs. 4 and 11 show the leaves in their natural position, those of Castanea lying along the stalk, while those of Acer are ranged round it. In both cases it will be seen that there is practically no overlapping, and very little waste of space. In Castanea the stalks are just long enough to give a certain play to the leaves. In Acer they are much longer, bringing the leaves 352 THE POPULAR SCIENCE MONTHLY. approximately to the same level, and carrying the lower and outer ones free from the upper and younger ones. Now, if we arrange the Spanish-chestnut leaves round a center, as in Fig. 12, it is at once obvious how much space is wasted. On the other hand, if we attach the leaves of the Acer to the stalk of Castanea at the points from which the leaves of Castanea came off, as in Fig. 13, Fig. 12. Fig. 13. we shall see that the stalks are useless, and even mischievous, as a cause of weakness and of waste of space ; while, on the other hand, if we omit the stalks, or shorten them to the same length as those of Cas- tanea, as in Fig. 14, the leaves would greatly overlap one another. Once more, for leaves arranged as in the beech the gentle swell at the base is admirably suited ; but in a crown of leaves, such as those of the sycamore, space would be wasted, and it is better that they should expand at once as soon as their stalks have borne them free from those within. Moreover, the spreading lobes leave a triangular space (Fig. 11) with the insertion of the stalk at the apex, which seems as if expressly designed to leave room for the pointed end of the leaf within. Hence we see how beautifully the whole form of these leaves is adapted to the mode of growth of the trees themselves and the arrangement of their buds. Before we proceed to consider the next series of species to which I wish to direct attention, it will be necessary for me to say a few words on the microscopical structure of the leaf. Although so thin, the leaf consists of several layers of cells. Speaking roughly, and as a general rule, we may say that on each side is a thin membrane, or epidermis, underneath which on the upper side are one or more layers of elongated Fig. 14. ON LEAVES. 353 cells known from their form as " pallisade-cells," beneath which is a parenchymatous tissue of more or less loose texture. The leaf is strengthened by ribs of woody tissue. From this general type there are, of course, numerous variations. For instance, some water-plants have no epidermis. If the surface of the leaf be examined with a tolerably high power, small opaque spots will be observed, resembling a sort of button-hole, with a thick rim or border composed of two more or less curved cells, the concavities being turned inward. When dry, they are nearly straight, and lie side by side ; but when moistened they swell, become somewhat curved, and gape open. It is difficult to realize the immense number of these orifices or " stomata " which a single bush or tree must possess when we remember that there are sometimes many thousand stomata to a square inch of surface. In a large proportion of herbs the two sides of the leaf are under conditions so nearly similar that the stomata are almost equally numerous on the upper and on the lower side. In trees, however, as a general rule, they are found exclusively on the under side of the leaf, which is the most protected ; they are thus less exposed to the direct rays of the sun, or to be thoroughly wetted by rain, so that their action is less liable to sudden and violent changes. There are, however, some exceptions ; for instance, in the black poplar the stomata are nearly as numerous on one side of the leaf as on the other. Now, why is this ? If we compare the leaves of the black and white poplar, we shall be at once struck by the fact that, though these species are so nearly allied, the leaves are very different. In the white poplar (Populus alba), the upper and under sides are very unlike both in color and texture, the under side being thickly clothed with cottony hairs. In the black poplar (P. nigra, Fig. 15), the upper and under surfaces are, which is not frequent, very similar in color and texture. The petioles or leaf -stalks, again, are unlike ; those of P. nigra presenting the pe- culiarity of being much flattened at the end toward the leaf. The effect of the unusual structure of the petiole is that the leaf, instead of being horizontal as in the P. alba and most trees, hangs vertically, and this again explains the similarity of the two surfaces, because the result is that both sur- faces are placed under nearly similar conditions as regards light and air. Again, it will be observed that, if we attempt to arrange the leaves of the black poplar on one plane, they generally overlap one another ; the extent is larger than can be displayed without their in- terfering with one another. In foliage arranged like that, for instance, vol. xxvii. — 23 Fig. 15. 354 THE POPULAR SCIENCE MONTHLY. of the beech, elm, sycamore, or, in fact, of most of our trees, this would involve a certain amount of waste ; but in the black poplar, as Fig. 15 shows, the leaves when hung in their natural position are quite detached from one another. Another interesting case of a species with vertical leaves is the prickly lettuce {Lactuca scariola), while those of L. muralis and L. virosa are horizontal. With this position of the leaves is connected another peculiarity, especially well marked in the so-called " compass " plant of the American prairies (Silphium laciniatum), a yellow com- posite not unlike a small sunflower, which is thus named because the leaves turn their edges north and south. This has long been familiar to the hunters of the prairies, but was first mentioned by General Al- vord, who called Longfellow's attention to it, and thus inspired the lines in " Evangeline " : " Look at this delicate plant, that lifts its head from the meadow, See how its leaves are turned north, as true as the magnet; This is the compass-flower, that the finger of God has planted Here in the houseless wild to direct the traveler's journey Over the sea-like, pathless, limitless waste of the desert." The advantage of this position, and consequently the probable reason for its adoption, is that in consequence of it the two faces of the leaf are about equally illuminated by the sun ; and in connection with this we find that the structure of the leaf is unusual in two respects. The stomata are about equally abundant on both surfaces, while pallisade- cells, which are generally characteristic of the upper surface, are in this species found on the lower one also. The leaves of the Lactuca scariola have also, when growing in sunny situations, a tendency to point north and south. Under such circumstances also they have a layer of pallisade-cells on each side. Hitherto I have dealt with plants in which one main consideration appears to be the securing as much light and air as possible. Our Eng- lish trees may be said as a general rule to be glad of as much sun as they can get. But a glance at any shrubbery is sufficient to show that we can not explain all leaves in this manner, and in tropical countries some plants at any rate find the sun too much for them. I will pres- ently return to the consideration of the general characteristics of tropi- cal vegetation. In illustration, however, of the present point, perhaps the clearest evidence is afforded by some Australian species, especially the eucalypti and acacias. Here the adaptations which we meet with are directed, not to the courting, but to the avoidance, of light. The typical leaves of acacias are pinnate, with a number of leaflets. On the other hand, many of the Australian acacias have leaves (or, to speak more correctly, phyllodes) more or less elongated or willow-like. But if we raise them from seed we find, for instance, in Acacia salicina, so called from its resemblance to a willow, that the first leaves are pin- ON LEAVES. 355 nate (Fig. 16), and differ in nothing from those characteristics of the genus. In the later ones, however, the leaflets are reduced in number, and the leaf-stalk is slightly compressed laterally. The fifth or sixth leaf, perhaps, will have the leaflets reduced to a single pair, and the Fig. 16. Fig. 11. leaf-stalk still more flattened, while, when the plant is a little older, nothing remains except the flattened petiole. This in shape, as already observed, much resembles a narrow willow-leaf, but flattened laterally, so that it carries its edge upward, and consequently exposes as little surface as possible to the overpowering sun. In some species the long and narrow phyllodes carry this still further by hanging downward, Fig. 18. Fig. 19. and in such cases they often assume a cimeter-like form. This I would venture to suggest may be in consequence of one side being turned out- ward, and therefore under more favorable conditions. In one very interesting species {Acacia melanoxylon, Fig. 17), the 356 THE POPULAR SCIENCE MONTHLY. plant throughout life produces both forms, and on the same bough may be seen phyllodes interspersed among ordinary pinnate leaves, the re- spective advantages being, it would appear, so equally balanced that sometimes the one, sometimes the other, secures the predominance. In the case of the eucalyptus, every one who has been in the south of Europe must have noticed that the young trees have a totally dif- ferent aspect from that which they acquire when older. The leaves of the young trees (Fig. 18) are tongue-shaped, and horizontal. In older ones, on the contrary (Fig. 19), they hang more or less vertically, with one edge toward the tree, and are cimeter-shaped, with the convex edge outward, perhaps for the same reason as that suggested in the case of acacia. There are several other cases in which the same plant bears two kinds of leaves. Thus, in some species of juniper the leaves are long and pointed, in others rounded and scale-like. Juniperus chinensis has both. In the common ivy the leaves on the creeping or climbing stems are more or less triangular, while those of the flowering stems are ovate-lanceolate, a difference the cause of which has not, I think, yet been satisfactorily explained, but into which I will not now enter. — Contemporary Heview. -++*- EAETHQUAKE PHENOMENA. By EALPH S. TAEE. AT the present time the earth seems to be in a state of great seis- mological action. Different parts of the world have recently been disturbed by earthquakes which have caused wide-spread destruc- tion. Those in Spain, which began December 24th, and have lasted, with slight interruption, down to the time of writing, have been among the most destructive of recent earthquakes. Over two thousand people have been killed, many more wounded, and thousands of houses de- stroyed. Such a state of affairs can not help arousing an interest in this phenomenon. The earth is constantly quivering, some point on the surface being the seat of a slight quake neaidy every moment of the day. By far the larger number of these are of little intensity, being felt only by delicate instruments, and the majority of cases come from volcanic re- gions. So few facts are known, that we can neither draw deductions nor even determine the causes. It is reported, however, that earth- quakes more commonly occur at night, and that they are more abun- dant in winter than in summer. The only settled facts about earthquakes are, that they are the re- sult of some shock imparted to the rocks at a considerable distance be- neath the surface, and that this shock reaches the surface in a series EARTHQUAKE PHENOMENA. 357 of concentric rings, all points on the circumference of each ring receiv- ing the shock at the same moment, even though they may be hundreds of miles apart. In other words, all points at equal distances from the center of the earthquake receive the shock at the same moment. Al- though this is theoretically the case, according to well-known physical laws, still, in practice, the facts are somewhat different ; for the shock is retarded or accelerated according as the rock opposes or favors the passage of the wave. The seventy of the shock in a given place is dependent upon a variety of causes. These are : 1. The strength of the original shock ; 2. The distance from the earthquake center ; and, 3. The kind of rock on which one is standing, loose gravels greatly diminishing: the force of the shock. The destructiveness of earth- quakes depends rather upon the suddenness of application than the amount of motion. In that at Rio Bomba, it is reported for a fact that a man was hurled across a stream a distance of one hundred feet, and landed on an elevation fifty feet higher than his original position. It is an undoubted fact that objects are frequently thrown great dis- tances. In the Mississippi Valley, during the earthquakes of 1811 to 1814, the tops of trees were twisted and entangled, and strong log- cabins were thrown to the ground. Rivers are sometimes checked in their flow, and, in past geological ages, some have been completely turned from their course by earthquakes. At least four theories have been seriously advocated by scientists to explain these phenomena. The first, which is now abandoned, is based upon the supposition that the earth's interior is in a fluid condi- tion. This being the case, the combined action of the sun and moon upon this molten mass beneath the surface causes it to surge and swing in tides of liquid fire. It is the shock from this that we feel on the surface. (I dismiss this theory, as one having no value whatever). Another theory is, that earthquakes are due to volcanic action. The passage of the immense quantities of gas which escape from volcanoes must necessarily cause shock after shock. This gas, under pressure of thousands of pounds, is contained in a subterranean boiler, from which it is continually trying to escape. The moment the press- ure becomes sufficient, the walls in some part give way, and the trans- mission of this shock reaches us as an earthquake. When the pent-up gases have broken through successive strata, always coming nearer to the surface, they finally reach the uppermost stratum, and this, which has been weakened by previous eruptions, gives way before the press- ure, and lets the steam out as a volcanic eruption. It is thus, then, that the continual succession of earthquakes in volcanic regions is produced. When, however, we study the country about many earth- quakes, and find no evidence of volcanoes, we are forced to abandon this theory for those regions, and look further. This is the case with all New England earthquakes, and with those in Spain. 358 THE POPULAR SCIENCE MONTHLY. Let us look at the next theory. We all know that water is con- tinually soaking into the ground, and is dissolving out all matter which it can. Limestone is one of these substances, and it is to this property that we owe the great caverns of Kentucky. Water not only works on or near the surface, but it even penetrates thousands of feet into the earth, and at this depth possesses even greater power of solution. Indeed, we have every reason to believe that deep down in the earth's crust vast caverns have been excavated by this erosion of water, and that in some places, especially limestone regions, these are numerous. Granting, then, that there are such great holes in the ground, and supposing that one of them should suddenly collapse, we can readily imagine a shock which would cause wide-spread devas- tation. But this theory also will apply merely to certain limited localities, and we have not yet found a general theory — one for all regions. Let us travel for a moment in a mountainous region, and we will see thousands of feet of rock folded, twisted, and bent in every con- ceivable manner. Now, it is a well-proved fact that these rocks were originally deposited in a horizontal layer, and that they have since undergone contortion. It can be conceived, then, that such rocks must be in a constant state of strain ready to relieve themselves at any favorable moment. Let us suppose that we have a long board held down on each end by a bank of earth. Remove a part of one bank, and a point will be reached when the board will spring up with con- siderable force, striking anything above it a severe blow. This is the condition of our mountain-rocks. Material is constantly being eroded from some and piled upon others. The time finally comes when they snap or spring, and, striking the rocks above, send out an earthquake shock. Quarrymen frequently feel a slight shock, and immediately after hear a report, showing that the strain in some rock has been relieved. A most curious instance is reported where a very long col- umn of granite rock was being split from a quarry by the use of wedges. At last the mass was split from the bed, and instantly it expanded itself with such suddenness as to produce a very perceptible jar ; and when the rock was returned to the place where it originally lay it no longer fitted, and the drill-holes did not coincide as before. Here, then, we have an earthquake on a small scale started by artifi- cial means. Probably many of the slight shocks result from similar causes, or from the action of frost, or by contraction and expansion caused by the daily change in temperature. These, then, are the theories for earthquakes, but neither of the three can be called general. We can usually tell when volcanic action is the cause, and are thus limited in our choice to two. In some cases the cavern theory may apply, but these are rare, and can usually be determined, so that in any region not volcanic the third theory is the most probable. This accounts for the fact that earthquakes are much EARTHQUAKE PHENOMENA. 359 more frequent and violent in mountain-regions of recent origin. The Appalachian, which are the oldest mountains in America, are, there- fore, very free from earthquakes, because the rocks have, as a rule, long since relieved themselves ; while, on the other hand, the compara- tively new Rockies are the seat of more frequent tremblings. There is a theory for the cause of earthquakes, which is rather neglected by scientific men, but which, I think, will explain many of those phenomena not otherwise accounted for. At the mouth of the Ohio, and at Newburyport, Massachusetts, both of which have in times past been the seat of very severe earthquake shocks, the layers of rocks are not badly bent. And, further, I do not see how the theory of bent rocks can explain the frequent repeti- tion of shocks which we have recently seen in Spain, in Newbury- port in 1727, and near the mouth of the Ohio in 1811. These regions had been comparatively quiet for years, and suddenly a severe shock was felt, followed by a series of successive shocks, which, in the case of Spain, have not yet ceased, although the original shock occurred December 24, 1884. The theory, which I have spoken of, and which would explain this, is that there are great quantities of gas accumu- lated at certain points beneath the surface under great pressure, and that this gas, in its attempt to free itself, bursts open the rocks, causing shock after shock, until it has finally relieved itself sufficiently to re- main quiet. This, one will see, is similar to the volcanic theory, except that there is no necessity for the presence of a volcano. What this gas is, does not matter ; it may be accumulations of steam, or it may be evolved from petroleum, or it may be carbonic-dioxide gas evolved by acids working on calcareous rocks. In the Newburyport earthquake, which was the most severe ever recorded in New England, large quan- tities of gas escaped to the surface; and, on the Ohio, gas also escaped. This shock, which was at first wide-spread, finally narrowed itself down to a very limited marshy area and died out. To sum up, then, it may be said: 1. That in volcanic regions earth- quakes are a part of an eruption, premonitory warnings ; 2. That in a limestone country the falling in of the walls of caverns may ac- count for some ; 3. That in regions of recent mountain-making the sudden release of tension causes many ; 4. That the pressure of pent- up gases on the surrounding rocks, which are finally burst, may be the cause of a large number, more especially those which are followed by a long-repeated series of shocks ; and, finally, that in any one of these regions either or all of the other causes may (with the excep- tion of volcanic in non-volcanic regions) enter into the production of earthquakes. 360 THE POPULAR SCIENCE MONTHLY. CURIOSITIES OF STAR-FISH LIFE.* By FEEDEEIK A. FEENALD. FOR a dozen years past, the eminent English zoologist, who has become so widely known as an investigator of animal intelli- Fig. 1.— Upper Surface of a Star-fish {Astropecteri). (From CaBselTs "Natural History.") gence, has spent his summers at the sea-side, studying several common forms of marine life. He compares a season's work of this kind to a prolonged picnic, the pleasure of which is accompanied by a sense that no time is being profitlessly spent. Sail- ing about upon the sunny sea to dip up in muslin nets the creatures at the surface, steaming away far from shore to dredge for other material, and carry- ing on observations among the tanks and bell-jars of a neat little airy workshop, all have their charms. Even the neces- sity of devising makeshift apparatus, and of teaching unskilled hands how to help, adds to the enjoyment, as does the over- coming of similar obstacles in a pleasure- excursion. Dr. Romanes has devoted his attention mainly to jelly-fish, star-fish, Fig. 2.— PedicellarijB (magnified). (From Cassell's " Natural History.") * The material and illustrations of this article are drawn from " Jelly-fish, Star-fish and Sea-urchins," by Dr. G. J. Romanes, the latest issue in the International Scientific Series. CURIOSITIES OF STAR-FISH LIFE. 361 and sea-urchins, or more particularly to the nervous systems, and the movements controlled by them, in these creatures. A star-fish, as we all know, consists of a central disk and five radi- ating arms (Fig. 1). Upon the whole of the upper surface occur numerous calcareous nodules imbedded in the soft flesh, and support- ing short spines. One of these nodules, much larger than the others, is always found a little to one side of the center, and is called the madreporic tubercle (Fig. 1, m). With the aid of a lens we may see also on the upper surface a number of small organs, each consist- ing of a pair of pincers supported on a flexible stalk, scattered about among the calcareous nodules, or attached to the spines ; these are known as pedicellariae (Fig. 2). These organs are provided with mus- cles' by which the stalk is swayed about, and the pincers are opened and shut. What it is that these cm-ious organs are adapted to seize, and therefore of what use they are in the economy of the animal, has long been a puzzle to naturalists, but Dr. Romanes and his associate, Professor Ewart, have succeeded in throwing some light on this point. In some species of star-fish the size of the central disk is increased so as to fill up the spaces between the rays, the form of the animal thus becoming a pentagon. In other species the reverse process has taken place, the rays having become relatively longer, and, being at the same Fig. 3.— A Brittle-stab. (From Cassell'e " Natural History.") time very active, they look like five little snakes joined together by a small circular disk (Fig. 3). Again, in another species the rays branch, these branches again branch, and so on till the animal looks like a mat. Turning now the under surface of our star-fish uppermost, we see that the mouth is in the center of the disk, and that from the mouth radiate 362 THE POPULAR SCIENCE MONTHLY. five grooves, each extending to the tip of one of the five rays (Fig. ?). On each side of these grooves are many actively moving membranous tubes, which are used for crawling, and are called the pedicels or feet. They are closed at the free end, but communicate by a system of tubes within the body of the animal with the madreporic tubercle. It has been surmised that this tubercle acts as a filter to the sea-water which, with some admixture, forms the liquid circulating in the tubes, and Dr. Romanes has proved the surmise to be correct ; for colored fluid, injected under pressure into any part of the system of tubes, found its way to the madreporic tubercle, and oozed through its porous substance. The tube-feet are thrust forth or with- drawn by being distended with liquid or emptied. With the exception of a few at the tip of each arm, every tube-foot bears a sucker (Fig. 4) ; these suck- ers are pressed closely to a flat surface by filling the tube-feet with liquid ; the pressure within the tubes is then lessened, and the greater pressure of the sur- rounding water holds the suckers fast. They are released by increasing the pressure of the liquid Fig. 4. -The Terminal within the tube-feet. Portion op a Tube- rr\^ n i n i • t ± foot (magnified). lhe common star-nsh usually crawls in a deter- minate direction, the feet on the tip of the foremost ray being used as feelers. In a tank, when the star-fish has ascended the side and reaches the surf ace of the water, it often performs peculiar movements which may be called acrobatic. The animal does not wish to leave its native element — in fact, can not do so, because its sucking feet can act only under water — neither does it wish to descend at once. Fio. 5— Natural Movements op a Star-pish on reaching the Surface cp Water. It therefore crawls along the side of the tank, now and then throwing back its uppermost ray or rays to feel about for rocks or sea-weed (Fig. 5). If it finds any solid support it will very likely attach its CURIOSITIES OF STAR-FISH LIFE. 363 uppermost rays to it, and then, letting go its other attachments, swing from the old support to the new. The activity and co-ordination mani- fested in these acrobatic movements, says Dr. Romanes, are surprising, and give to the animal an almost intelligent appearance. The feet of astropecten are partly rudimentary, having lost their terminal suckers, and these star-fish assist themselves in locomotion by the muscular movements of their rays. The brittle-stars are still fur- ther removed in the same direction from the common star-fish ; their tubular feet are of no use for crawling, while their rays are so long, flexible, and muscular, as to enable them to shuffle quite rapidly over horizontal surfaces. Two opposite arms are used upon the floor with the motion of swimming, the animal leaping forward about two inches at each stroke, and, as these leaps follow one another quickly, the star- fish is able to travel at the rate of six feet a minute. A common star- fish can crawl only two inches a minute. Some of the Comatulce, in which the muscularity of the rays has proceeded still further, are able actually to swim by the co-ordinated movements of their rays. The sea-urchin, or echi- nus, is a modification of the star-fish structure, hav- ing the form of a flattened sphere, and is covered with hard spines (Fig. 6). In the living animal these spines are movable in all directions, each being mounted on a ball-and- socket joint, and provided with muscles at its base. Like the star-fish, the echi- nus has a madreporic tu- bercle, pedicellariae, and feet. If we shave off the spines and pedicellariae, we come down to a hard shell, which is hollow and filled with liquid. The liquid resembles sea-water, but is richly corpusculated, and co- agulates when exposed to the air. Five double rows of holes extend symmetrically from pole to pole of the shell. It is through these holes that the feet are thrust out, so that in its main features an echinus is merely a star-fish with its five rays curved into the shape of a hollow spheroid, and then converted into a rigid box, with holes left for its feet to come through. The urchin crawls in the same way as the common star-fish, but makes use of its spines also to help push itself along. The suckers, moreover, in being protruded from all sides of a globe instead of from the under side of a flat organ- ism, are of much more use as feelers than they are in the star-fish. If Fig. 6.— An Echtntts partly denuded of its Spines. (From CasseH's "Natural History.") 364 THE POPULAR SCIENCE MONTHLY. the animal while walking be turned half round, it will continue its movements as before, and hence will proceed in a direction opposite to its former one. When at rest, some of the feet are used as anchors, and others protruded as feelers. All species of the Echinodermata, when turned upon their backs, are able to right themselves. The brittle-stars can easily perform the Fig. 7.— Natural righting Movements of Common Star-pish. needful manoeuvre by wriggling some of their snake-like arms under the inverted disk, and heaving the whole body over by the mere mus- cularity of these members. The common star-fish, however, experi- ences more difficulty, and executes the manoeuvre mainly by means of its suckers. It twists round the tip of one or more of its rays until the feet there situated are able to get a firm hold of the floor (Fig. 7, tffllltllllllllllHllllllllllllllllllllllllllllllllH^ Fig. 8. a), then, by successive action of the feet further back in the series, the whole ray is twisted round (b), so that the under surface of the end is applied flat against the floor (c). The semi-turn or spiral then travels CURIOSITIES OF STAR-FISH LIFE. 365 on down the ray. Usually two or three adjacent rays perform this manoeuvre simultaneously, the spirals of the co-operating rays being invariably turned in the same direction, and, when they have proceeded sufficiently far to drag over the remaining rays, these then abandon their hold on the bottom so as not to offer any resistance to the lifting action of the active rays. The whole movement does not occupy more than half a minute. But it is in the case of echinus that these righting movements become most interesting, from the fact that they are so much more difficult to accomplish. Two, or perhaps three, adjacent rows of suck- ers are chosen out of the five to accomplish the task. As many feet in these rows as can reach the floor are thrust downward and fastened firmly to it ; by their combined action, as by the pull of liliputian ropes, the globe is tilted slightly in their own direction, the anchoring feet in the opposite rows releasing their hold on the floor to admit of this tilt- ing (Fig. 8). The next feet in the active rows are thus enabled to reach the floor, and, when they have established their hold, they assist in increasing the tilt ; then the next feet in the series lay hold, and so on, the globe slowly but steadily rising until it stands upon its equa- tor (Fig. 9). The difficulty of raising such a heavy mass into this Fig. 9. position by means of the slender motive power available is manifest not only from the extreme slowness with which it takes place, but because specimens not perfectly strong may fail completely to reach the position of resting on the equator. Moreover, in some cases when this position has been reached with difficulty, the echinus gives itself a breathing-space, as it were, before beginning its descent. It will be perceived that, as soon as the descent begins, gravity is no longer an obstacle but an aid to the righting movement, and it might be anticipated that the echinus would now simply let go all its attach- 366 THE POPULAR SCIENCE MONTHLY. ments and allow itself to roll over into its natural position. But an echinus will never let go its attachments without some urgent reason, seeming to be above all things afraid of being rolled about at the mercy of currents, and therefore it lets itself down almost as slowly as it pulled itself up (Fig. 10). Single rays separated from a star-fish crawl as fast as the entire animal, and likewise in a determinate direction. They also crawl up Fig. 10. perpendicular surfaces, and when inverted right themselves as quickly as do the unmutilated creatures. A segment of an echinus bearing a single row of ambulacral feet, when propped up on its ab-oral pole, (Fig. 11) will right itself after the manner of entire animals (Fig. 12). It, however, experiences more difficulty in doing so, and very often fails to complete the manoeuvre. Such a segment is, of course, analo- gous to a single detached ray of a star-fish ; but on account of the rigid consistence and awkward shape of the segment — standing erect instead of lying flat — it presents a much more curious appearance in locomotion than does the ray of a star-fish. Dr. Romanes reports observations which show conclusively that the whole external surface, not only of the soft and fleshy star-fish, but even of the hard and rigid echinus, is everywhere sensitive to stimulation. This sensitiveness, moreover, is highly delicate. If any part of the external surface of an echinus is lightly touched with the point of a needle, all the feet, spines, and pedicellarise within reach of that part, and even beyond it, immediately close in upon the needle and grasp it tightly. This simultaneous movement of such a little forest of prehensile organs is a very beautiful spectacle to witness. Here we have proof of the function of the pedicellarife. In climbing perpendicular or inclined surfaces of rock covered with waving sea- weeds, it must be of no small advantage to an echinus to be provided on all sides with a multitude of movable stalks bearing forceps, which can instantly seize a passing frond. The frond being thus arrested, the spines come to the assistance of the pedicellarise, and both to- gether hold the sea- weed steady till the ambulacral feet have time to CURIOSITIES OF STAR-FISH LIFE. 367 establish their hold upon it with their sucking-disks. This operation may be witnessed by drawing a piece of sea-weed over a healthy echinus in the water. The capability of the spines for co-ordinated action is highly re- markable and interesting. Thus, for instance, if an urchin be taken Figs. 11 and 12.— Righting and Ambulachal Movements of several Segments of Echinus. out of the water and placed upon a table, it is no longer able to use its feet for walking, as the suckers can act only under water. Yet the animal is able to progress slowly by means of its spines, which are used to prop and push the globe-like shell along in some continu- ous direction. If a lighted match be held in front of the moving ani- mal, as soon as the echinus comes close enough to feel the heat, all the spines begin to make the creature move away in the opposite direction. There is an urchin-like form of echinoderm called spatangus, which differs from the echinus in having shorter feet and longer spines. When, therefore, a spatangus is inverted it is unable to right itself 3 68 THE POPULAR SCIENCE MONTHLY. by means of its short feet, but uses its long spines to perform the manoeuvre. The process is a tedious one, and there are generally numerous failures ; but the creature perseveres until it eventually succeeds. -♦*♦- ETHICS AND THE DEVELOPMENT THEORY. By GEOEG VON GITZYCKI. THE question of the bearing of the theory of evolution upon morals deserves a serious examination. The doctrine of development breaks at many points with cherished traditional notions, and its op- ponents have predicted that it would result in a spiritual revolution which would convulse society to its foundations by destroying the sanc- tions of conscience and paralyzing the religious sense. The science of ethics has a theoretical and a practical part ; the former, founded on the study of the nature of volition and the moral feelings, the latter having for its object to determine what ought to be. The latter, the establishment of rules of conduct, is the real ob- ject of ethics, while the purely theoretical researches have only the value of means. Ethics can, it appears to us, learn much out of the theory of devel- opment, or can at least find a confirmation of single principles hitherto recognized by only a part of the students of morals. This theory teaches that the feelings and inclinations, as well as the bodily forms, are results of the adaptation of the living being to the conditions of his existence, and are therefore to be recognized as life-maintain- ing functions ; that, the more complicated are the conditions of life, the less perfect is this adaptation : therefore, in the human world, spontaneous feelings and impulses are not safe guides. "We may learn from it, also, to regard the moral feelings and conceptions as the most important part of the adapting of man to the conditions of social existence. It teaches us to bring into special considera- tion the moral conceptions of the most successful nations in the struggle for existence ; for, if their views of right and wrong had diverged greatly from what is really beneficial to society, they would not have reached their dominant position. But the recognition that, in conse- quence of the complicated conditions of life, the adaptation is never complete, must restrain us from ever regarding the " positive morals " of a people — that is, the sum of their actual moral ideas — as being ab- solutely perfect. The development theory, which has made us acquainted, as perhaps no former generation has been, with the idea of progress, has also ac- customed us to regard the moral as one of the fields in which progress takes place ; and, furthermore, to look forward to perfection in the ETHICS AND THE DEVELOPMENT THEORY. 369 moral nature. Moral progress consists, not in men coming nearer to their ideals, but in their ideals reaching a higher plane. This theory shows us how dependent man is upon his race, and how erroneous it is to separate him from that connection. That the faculty of conscience is a result of the adaptation of man to the con- ditions of social existence appears to he doubted by no adherent of the theory of development ; but the exponents of the doctrine vary greatly in their views of the manner in which the moral conceptions arise in individual life. Some regard them as to a greater or less extent in- stinctive, or transmitted by inheritance from the accumulated experi- ence of ancestors ; while others are inclined to accord a more promi- nent agency in the matter to training. We may apparently, however, presume that that which is practically the most wholesome will endure in the character, provided the teacher does not trust too much to the innate moral instincts, but recognizes that, while his child has the qualities requisite to his becoming a moral man under favorable con- ditions, this is not sure to be the case if those conditions are wanting, and therefore exercises extreme care in moral instruction. "We turn next to the answer to the question, What is the bearing of the development theory on the practical part of ethics? Man's place in Nature, as determined by that theory, is very different from that indicated in the older ideas of men ; just as the Nature in which man finds himself set is not the Nature that existed in the conceptions of the past. The new conception of man and his morals again ap- proaches, in many respects, that which was implied in the ethics of classical antiquity. Man no longer stands outside of Nature, but within it, as one of its integral parts. He is subject to the same laws of life as the animals. All in him, like all around him, is a product of natural, regular development. Even his moral part is not something laid upon him from outside of Nature, but something which has been shaped out of his own nature, molding itself according to the conditions of his existence. To an ethicist who accepts this view, morals will ap- pear an affair of humanity and for humanity — for humanity on earth ; and will give the most comprehensive construction of the saying of Christ, that man is not made for the Sabbath, but the Sabbath for man. We can not perceive that this view involves any practically destructive tendencies ; and there are not a few distinguished men who avow the belief that there is no irreconcilable variance between evolution and religion. With this view of the place of man in Nature, the ethicist can not easily oppose the doctrine that the same legality rules in the human will as in all the other processes of Nature. Even in the matter of the appearance of new individuals, the development theory admits no void in the endless chain of causation ; for the dispositions which man brings into the world are, in consequence of it, nothing else than a product of the energies of his predecessors. The recognition of the TOL. XXVII. — 24 370 THE POPULAR SCIENCE MONTHLY. fact of the transmissibility of mental as well as of physical character- istics, if not to the children to the children's children — a transmissibil- ity whose sphere of influence in individual cases is not susceptible of definition — can not but heighten the feeling of responsibility, because we are thereby made aware that the consequences of good as well as of bad conduct extend further than we had supposed. A few adherents of the development theory, including Darwin himself, have held that not the good of mankind, but the maintenance of his existence, is the moral principle resulting from it ; and that feelings of pleasure and of pain are only the means which Nature uses to promote the exercise of life-favoring and restraint from life-injuring conduct ; that the real end of all action is not pleasure and the avoid- ance of pain, not the greatest possible excess of pleasure over pain for as many as possible, not the greatest good of the greatest number, but only the most prolonged existence of the greatest number. The greatest possible endurance of species, or the mere maintenance of species, not their welfare, would be according to this view the chief moral principle. This position appears to us to be a difficult one. The chief moral principle expresses that from which all of the rules of right may be derived, and accordingly means the highest rule of conduct, the highest moral aim of life, or the ethical highest good, and serves as the highest standard of estimation and judgment. Those evolutionists of whom we have just spoken start from a teleological view of the world — from the view that the course of Nature is gov- erned by some purpose. But the majority of the Darwinians are op- ponents of teleology, or try to be. Rolph has shown that, in follow- ing the history of organic development on the earth, we can really perceive no tendency to an adaptation showing design, to the produc- tion of forms that may be represented to human conception as higher. Its result has been only to produce forms better adapted to what is around them ; and the change just as often consists in a deterioration, even though some advantage is always gained for the creature. As not final causes, but efficient causes, working causes, have worn out the river-bed and determined the course of the stream, as it has formed its channel not with reference to its final outlet, but to the local con- ditions, so, as Darwin and his followers have shown, it is with all or- ganic phenomena. The investigator has to break with teleology in all its forms ; and, even in ethics, the question of the object, of the destiny of man, will have to be given up. This idea of a purpose or design in Nature, when we come to analyze it, of a preconceived and voluntary operation working to produce determined effects, presumes by necessary implication the agency of a will behind the causes which are leading up to those effects. It follows, hence, that there is purpose in Nature in the domain of man and the higher animals, because men, and in a certain but very much less degree the animals, form con- ceptions of processes which they strive to carry through ; but that ETHICS AND THE DEVELOPMENT THEORY. 371 aside from these one can speak of Nature's purposes, of purposes which general Nature is pursuing, only if he regards Nature as a thinking and volitional being, or as the creature of such a being. A teleological view of the world thus of necessity always includes some kind of a theological view ; and it seems to be decidedly a non-sequitur to en- tertain the one without holding to the other. We men actually make our continued existence an object of fun- damental importance, because, without realizing it, no other object is attainable. We are thus justified in calling all our properties that contribute to the maintenance of life adapted to that purpose. And, as we refer this same relation to the animal and the whole organic world, we are accustomed also to designate all their life-maintaining properties as likewise adapted. But life is never a purpose to animals. The idea of preserving life does not arise in their consciousness, and can not therefore be the object of a volition ; while the lower animals have no ideas, but only sensations and perceptions. They have, there- fore, no purposes. Still less can we speak of the purposes of plants, for plants have no consciousness. It is thus clear that, so far as the sub-human world is concerned, the designation of the life-preserving attributes of existence as designed, unless we are speaking in a theo- logical sense, is only metaphorical. For this designation implies the premise that life is an object ; and this, in a proper, untheological sense, is true only as respects human consciousness. Thus, a speaker who would avoid transcendental implications and metaphorical modes of speech should always avoid the word " designed," and this can be done without leaving any fact undetermined. But, if we, regarding our belief in God as a justification for the introduction of the divine idea into science, and not heeding the many difficulties which ethics has hitherto encountered in basing its precepts on the presumed will of God, endeavor to determine what his will is, we shall have very little, if any, success in convincing the faithful that it is for the most prolonged existence of the greatest number. Even as relating to men, these persons will not believe that self- preservation as such is the highest good. Bare existence is no good, much less the highest good ; but it may be, if it is a bad existence, the highest evil, and this according to the perfectionist doctrine as well as according to the utilitarian theory of happiness. There is said to be existence, yes, eternal existence, even in hell ; and, according to the ancient fathers of the Church, " the most prolonged existence for the greatest number." Evolutionists, who recognize that life is valuable only as it is good, have occasionally fallen into the mistake of considering among the consequences of conduct only the effects on the condition of soundness, and of disregarding the pain that may be immediately produced by it ; and they have not always been mindful that, according to their own 372 THE POPULAR SCIENCE MONTHLY. definitions, fullness of life can be valuable only if we include in it full- ness of happiness or some cause thereof. Those evolutionists who appeal to the ancient principle of a Nature- fitted life have apparently not sufficiently considered one thing. Sci- ence teaches what has been, but not what will be. If the " tendencies " of Nature which they think they have determined were simply laws of Nature, conditions of the inevitable occurrence of events, there would be no reason in seeking to make a moral imperative of them ; for that can not be a matter of injunction wdrich will without fail happen of itself. But if those " tendencies " are not a fate to be fulfilled with irresistible necessity, but can be antagonized, then the question arises, Why should we act according to them, and not try to counteract them ? If we were once agreed that the complete working out of those tendencies would cross all our desires and hopes, would we rec- ognize the ethic imperative of promoting them ? On the contrary, we should recognize the obligation of so far as possible preventing their realization. And we should obey the moral command to make those tendencies ours, and advance them according to our strength so far as they appear good to us ; as we also should hold a corresponding con- duct to be right without this, without regarding it as advancing natural tendencies. What we should regard as good or evil, as worth striving for or to be avoided, must present a corresponding character to our own perception ; and what that is arises out of our own nature, not out of something different from what that might be. Thus, the final decision as to what is to be striven for and what to be avoided lies in us, in our mind and will. We observe, also, that the aspiration for what is according to Na- ture is so far from being an obvious ethical object, that the ancient Chi-istians regarded the natural as something leading to evil. The an- cient Greeks, on the other hand, premised an agreement of the two ; and so it came to pass that the former held a pessimistic and the lat- ter an optimistic view of the world. But the Greeks did not believe in the natural because it was natural, but because they thought it good ; as the Christians disbelieved in it because it appeared bad to them, and seemed to contradict their moral convictions. We are glad to learn from the evolutionist all he can tell us of the nature of things, and of the means of reaching the object sought after by us. Of this object, however, we do not learn from a natural his- tory of the objective world, but from the study of our own hearts. It is, therefore, self-evident that the utilitarian or the ethicist, who re- gards the highest general good as the chief moral standard, will make use of all knowledge that can cast light on the way to his end. Con- sequently, he will certainly avail himself of all the facts of biology and sociology that are of importance in regard to it. Existence is the condition of happiness. If the happiness of mill- ions of present and future living men is to be assured, then their exist- ETHICS AND THE DEVELOPMENT THEORY. 373 ence must be assured first of all things. Everything, therefore, that is important for the most prolonged existence of the greatest number is also important for the greatest happiness of the greatest number. The utilitarian will utilize all that the evolutionist can tell him — and one thing more. The evolutionist will tell him that there is a correlation, on one side, between disagreeable and destructive, and on the other side be- tween pleasurable and advantageous action ; that the "useful," in the sense of the pleasurable, nearly agrees with the useful in the sense of the life-maintaining ; and that there is a close connection between health and happiness and between disease and unhappiness. While this correlation is far from being perfect, it is, nevertheless, true that a more certain road to happiness lies through maintaining or improv- ing the health than through a direct striving after a maximum of pleas- ure. The same rule prevails in society. The sound health of society must be the practical end through reaching which alone the real pros- perity of society can be attained. The truth that health is a fundamental condition of happiness has, indeed, not been unknown to any ethicist ; that pattern of ancient cheerfulness, the philosopher Epicurus, is an emphatic reminder of this fact. And that the care of one's own health is enjoined also through regard for others, and that the so-called duties toward one's self are really duties toward others, and for that reason only duties, is likewise a doctrine that did not have first to be learned from Darwin and Spencer. But we have to thank Spencer for having adduced, in his exposition of the facts of transmission, so potent evidence of this truth, that no such dictum upon it as Schopenhauer has uttered will ever again be possible. While, however, he has performed the service of defining the physical conditions of happiness with greater emphasis than any of his predecessors, it does not follow that the utilitarian method founded by Bentham will have to be given up. Evolutionist writers have reminded us that too little attention has been paid to health in discipline and in public instruction. This is too true, but it is not in consequence of the application of utilitarian but of non-utili- tarian precepts. And if it has been declared to be one of the results of the doctrine of a correlation between species-maintaining and pleas- ure-bringing action that family happiness is the highest human happi- ness, that is only a confirmation of a view expressed long ago by utili- tarian ethicists, as appeared most plainly a hundred years ago (1785) in Paley's " Principles of Moral and Political Philosophy." If, however, by the phrase, " health of society," something else is understood than a society consisting of healthy individuals, then the word " health " is only a metaphor, and one the sense of which is not clear ; and to put this metaphor in the place of the principle of the happiness of the whole can not be regarded as an improvement. If Bentham should return now, he would have to censure the evolutionist 374 THE POPULAR SCIENCE MONTHLY. ethics in no slight measure for its vague generalities and empty decla- mations, and its playing with phrases, and to combat its lack of cir- cumspection. The evolutionists have joined generally with the utilita- rians, but they are not practical ethicists. They could hardly succeed in actually working with their principle in such a compass as Ben- tbam worked with his. We come now to consider what is the bearing of the Darwinian doctrine of the struggle for existence upon morals. The objection has been brought against this doctrine, in divers phrases and with a variety of statement, that it leads to extreme demoralization. It can not be denied that Darwin's designation of the principle discovered by him as the " struggle for existence " is not fortunate, and is a metaphor, indi- cating a conscious hostile contention between living beings, each seek- ing the other's destruction, that has no real existence as such. And it will not be disputed that Darwin has been led into errors similar to those embodied in the theory of Malthus ; or that great mischief has been done by the use of the phrase " struggle for existence " by per- sons who have never learned the A B C of ethics, but have still be- lieved themselves called to offer their crudities to the public. But those mistakes are not to be alleged against the principle as such. The principle of the natural selection of those beings whose modi- fications best adapt them to the conditions of their life is in the first place only an expression of that which has been, not of that which is to be. It is a law of Nature, not of morals. We are subject to this natural law of organic life, just as we are subject to the law of gravita- tion, or of the persistence of force, wholly without regard to our will. Natural selection is an agent which has operated as the general regu- lator of life upon the actual constitution of what is now existing in the organic world. It is the universal natural force that also regulates hu- man life. And what do we see in human life ? A fearful amount of moral and physical evil which is not prevented, but rather in part be- gotten by that regulator. We make it our task to contend incessantly by our premeditated action against that evil, while we regard the world, which is here without our assistance, not as the best possible, but as something which we must labor to improve and make more rational. What happens through the operation of the universal forces of Nature can not be a moral rule for us ; for those forces produce also everything that is bad. This regulating principle implies that the being which possesses the most advantageous constitution, that is, which is best adapted to the conditions of its existence, has the best chances to maintain itself and to increase ; and it applies to human beings as to all others. The fittest, or best adapted, survive. We have to distin- guish among the life-conditions of man, or in his environment, between the physical and the social factors ; the former regulating in general his physical, the latter his moral constitution. What, now, is the moral constitution which enables the individual ETHICS AND THE DEVELOPMENT THEORY. 375 endowed with it to maintain himself ? The principle of natural selec- tion is not contradicted by any fact in the history of mankind. The determination of what of its members shall survive is an affair of the particular constitution of a society. There are, as Everett * has re- marked, different kinds and degrees of immorality which are always important to the result. A certain degree of honor, according to the proverb, is required for a man to preserve his social standing in a so- ciety of thieves. But, besides the avoidance of flagrant violations of the social contract, there is nothing which is universally and always debarred by the demands of the social environment. The man who was fitted to succeed in the early days of the Roman Republic would have failed in the later age of the empire ; and one whom the social elements of the empire lifted up would have fared badly in the time of the republic. Indeed, societies in which the highest and noblest moral attributes are a passport to success are very rare. The "fittest " in the moral sense, and the " fittest " in the sense of Darwinism, are not often the same. And is this the last word that is to be said for Darwinism in its relation to morals ? Is the judgment that the moral best and the fit- test in the Darwinian sense are often not the same, of unconditioned effect ? We believe not. The principle of natural selection regulates not only the life of individuals ; it rules also over the lives of generations and of peoples. It may, indeed, happen to be the means of success in some one common- wealth to practice the religion of £ s. d. It may be that in a particular society selfishness, cunning, trickery, overbearing violence or fawning subserviency, and moral cowardice, or high living and ostentation, will give good chances for getting on ; men of such characters may have, in some states, the best opportunity to raise themselves and their families, while one who despises injustice, lying, and hypocrisy, will have to go to the wall. But there is, nevertheless, as Matthew Arnold says, "an eternal power, not ourselves, that makes for righteousness." Characteristics, it is true, are transmitted ; but not in the same com- binations as they existed in the father or the mother ; immoral charac- teristics, like those we have named, never in that which is adapted to insure success in a certain constitution of society. If we allow, by transmission or by training, some other peculiar quality to enter into the composition of the character, or if we let a certain quality be lost, then that "lucky balance" that brought success will be destroyed. The chances that the posterity of men possessing such traits of charac- ter as we have sketched will maintain themselves long, that they will not, sooner or later, fail, in consequence of collisions with the " physi- cal, legal, or social sanction," with the laws of health or of the state, or with the demands of society, are not very great. But "the eternal power, not ourselves, that makes for righteous- * C. C. Everett, in " Unitarian Review," October, 1878; "The New Ethics." 376 THE POPULAR SCIENCE MONTHLY. ness," asserts itself in a still more imposing manner. We have hith- erto considered only the lives of individuals and of single generations, but we must also regard the lives of peoples. It is manifest in this collective life, in a vastly higher measure than in individual life, that " the wages of sin is death." As Everett has remarked, again, one society may favor the growth of righteousness and honor, another that of knavery and hypocrisy. In one, drunkenness and sensuality, and similar vices, may cause a man to sink to the lowest circles of society ; in another, they may raise him till he reaches the highest. But here, at last, we have a principle, to which these social conditions are them- selves responsible. The one society will develop one type of charac- ter, the other a different one ; but according to the type of character which it favors will it stand or fall. In this we find in the facts of history a confirmation of the fundamental difference between right and wrong. What we call justice is the only enduring basis on which society can rest. The nations that do wrong and despise justice, which lose themselves in sensual intoxication, are at last broken up, and a purer, stronger, and less depraved race takes their place. If the opinion comes to prevail in a society that the struggle for existence justifies or demands a reckless pursuit of one's own interests, the oppression and ruin of the weak by the strong, the destruction of misery by destroying the miserable, the extirpation of the voice of compassion, which protests within us against such a course ; if phys- ical strength and refined cunning and selfishness are carefully cher- ished as the highest ideal, then the days of that commonwealth are numbered, for it has worked for its own dissolution by authorizing a " strife of all against all," which, true to its precepts, may come in at any moment when a community of interests may not be present. Let periods of want and danger, or of war, ensue, and we shall see what will be the fate of a society in which patriotism, devotion, ideal stand- ards, and regard for truth and justice have been objects of ridicule. All positive human authorities are subject to the authority of life- conditions. If they will not adapt themselves to the nature of things when they deal with the bases of social life, their enterprises will at last be shattered under the might of that authority. Two elements, according to Everett, have contributed more than all else to the success of men in the conflict with animals, and of civil- ized men in contending with barbarous. One of these elements is knowledge, or the power of thought, the other is the force of the social impulse. Ideas on the one side, a self -forgetting resignation on the other, are what have given the victory to the higher races. Whatever restricts the course of either mental or moral development strikes the hardest possible blow against the stability of the social organism. The distinction between right and wrong, to use an expression of John Fiske's, has its roots in the deepest foundations of the universe. The cosraical power of natural selection is not against, but for, morals. MOTHS AND MOTH-CATCHERS. 377 It sanctions the most exalted ethical ideals, such as the choicest minds have conceived. It is a judgment-power, because it permits only that which is right and perfect to endure, and lets the unjust, the base, and the evil perish. The knowledge that this world-power supports virtue, and con- tributes its part in elevating the moral nature, will inspire the moralist in his efforts in behalf of the good, and in his contention against the bad. But we must be careful not to mistake the true significance of this law. There is arising in the newer evolutionist literature a kind of fatalist optimism or optimistic fatalism, the effects of which may be no less disastrous than those of an undiscriminating pessimism. If natu- ral selection is to select the good, then the good must already be there. It does not contradict this principle, that the human race will die out as other species have died out ; but it follows directly from the prin- ciple that the race must die out if it becomes bad. Not without us, but through us, through our volition, conscious of that purpose, will the continuous development go on. In our day, says Salter, in his " Re- ligion of Morals," evolution is sometimes regarded as if it was some- thing outside of us and above us, and we had only to wait on its motion. But evolution operates through you and me. It is only an abstract name for the course which your energy and mine and that of other beings take. It is for better or for worse, according as we are better or worse. It goes on rapidly or creeps along painfully, accord- ing as our thoughts are quick or slow and dead. It is not enough to perceive that the bad will at last perish and the good persist. We must wish it to be the good that will triumph. It is still true that the sources of history are in us. The result of these considerations must be a heightening of the feeling of responsibility. — Translated for the Popular Science Monthly from the Deutsche Rundschau. -++*- MOTHS AND MOTH-CATCHERS. By AUGUSTUS E. GEOTE, A. M. IT. TO understand the way in which our North American moths are distributed (and by North American we mean the territory north of Mexico and the West Indies), we must study the physical geogra- phy of the continent. There is a perfect host of species and individu- als, which depend on special kinds of plants, for the most part, and their diffusion is, of course, limited by the area of the plant upon which their caterpillars subsist. But the greater bulk of the species are not confined in their young stage to one sort of plant, while, from their activity, these flying flowers, the moths, range farther than the more slowly traveling blossoms whose honey they extract. 378 THE POPULAR SCIEXCE MONTHLY. If we take a map giving a bird's-eye view of the continent, with the elevations marked, we can understand the problem better. Ranges of mountains obstruct, valleys and river-channels assist, the dispersion of moths. They travel on the wings of the wind, and an important factor is the prevailing seasonal direction of the air-currents. There is in North America a summer migration of many species from the South to the North, so that, toward the autumn, several tropical kinds have crept up along the coast, or inland, up the valley of the Missis- sippi. The " cotton-worm moth," which, in its caterpillar state, in- flicts great damage at times upon the plantations, is a case in point. Individual specimens or flocks of other moths, such as the " great eye- spot " {Erebus odora), the " blue and green hawk " (Argeus labritscce), visit us yearly, coming up from the West Indies. They die out in the winter here, and leave no progeny behind them to continue the species in our high latitudes. Rivers assist in the dispersion of insects, and, in a less degree, per- haps, the particular insects we are here discussing. Nevertheless, upon leaves and sticks the eggs of moths are floated on the current, while the commerce of the water-routes brings the cocoons with the vege- tables and fruits which it carries from place to place in boats and ships. A bird's-eye view of our continent shows us the elevations of the Rocky Mountains and parallel spurs in the West, and the Allegha- nies in the East. Mountain-ranges stand in the way of the spreading of moths, which perish in the cold atmosphere and the storms which gather about the rocky summits. Our fauna? can be understood by studying the formation of the land in this way. Over the vast plain east of Colorado the same kinds of moths generally prevail. The val- leys in the West, on the other hand, contain a majority of peculiar species or kinds, often more local than in the East. In New York we are cut off, again, by the Alleghanies from many species which are plentiful in Ohio and Indiana. Our tropical wanderers come to us up and along the coast. I have met, sailing on the Gulf Stream, flights of moths, mostly of a few kinds, which fell on the rigging and sides of the vessel in great numbers. In the autumn, on Staten Island, I have captured specimens whose true home was Cuba and Jamaica. Although smaller fauna?, or limits of particular species, are traced by naturalists, our mountain-ranges are the best general guide as to the changes in the sorts of moths which we may expect. From Ohio to Louisiana we meet much the same kind of moths, with a difference in the rarity of certain species, and in the presence of others dependent on particular kinds of plants. But, when we get into the valleys of the Rocky Mountains, we shall have taken leave of the most of our dusty-winged Eastern friends. Some kinds take the voyage with us completely across the continent, but these are comparatively few in number, and are sometimes almost cosmopolitan. So true is it that one branch of a subject leads to quite different MOTHS AND MOTH-CATCHERS. 379 questions and to matters apparently foreign to the immediate inquiry, that here the subject of the range of North American moths leads us into myth and poetry. For, in finding out that we have species of moths which are found in other continents, the question arises at once, How did they get here ? They could not fly over from Europe, nor could they now cross Behring Strait, with the Arctic climate there existing. Imaginative persons have supposed a submerged Atlantic Continent, which bridged the chasm in a remote geological period. The myth of the Atlantis has been recently furbished up under the facts supplied by the deep-sea soundings of the English steamer Chal- lenger, and the discovery of a plateau at the bottom of the ocean, be- tween North America and Europe. But, if it ever existed, it probably did so at a time before the ancestors of our present moths came into being. For a moment, let us leave this matter and look at the question of the affinities of our moths. I have shown, in the " American Journal of Science and Arts," the detailed characters of one family of our moths, the Sphingidce, and what is true of them is true generally. Our moths, in regard to their structural relationship with the moths of the world, fall into three main categories : 1. Those which are peculiar to North America. 2. Those which have their nearest allies in South or tropical America. 3. Those which have their nearest allies in Eu- rope or Northern Asia. With these last we have here to deal, and to account for their presence with us. This class falls into two main groups — those which are absolutely the same, and those which differ more or less, but clearly reveal their common ancestry. But there exists in these respects every gradation. Some differ so little that there is much dispute as to whether they constitute different " species," and some, again, only differ percep- tibly in certain stages. Others differ a little throughout in all stages, and form what are called " representative species." So, far off in Ari- zona, I have found a species ( Copimamestra occidenta) which " repre- sents " a common European species ( Copimamestra brassicce). What is this little moth, with its big name, doing in Arizona, and how did it get there? With regard to those kinds which are absolutely identical in America and Europe, some have evidently come over through com- merce in historic times. We have found out almost the particular voyage which brought the " Avhite-cabbage butterfly " from England to Quebec, whence the insect has spread over the New England and Middle States, to the great injury of our market-gardeners and cab- bage-growers. But of some the distribution is such that this can not be the explanation of their presence here. Of others it may be doubt- ful. I am inclined to believe that another cabbage-insect, the moth called Pluria ni, has been brought over in this manner. But how about our Arizonian Copimamestra? We shall have to leave entomology and go into geology to answer 380 THE POPULAR SCIENCE MONTHLY. this question. Formerly there was a warm climate in the north dur- ing the Tertiary period. This was a certain measurable time ago, when the circumpolar regions had a warm average temperature, with no winter, and the moths of the period were then substantially the same species from Norway across Siberia to Greenland. During this happy time — happy, at least, so far as weather was concerned — we must imagine that no impediment existed to the migrations of animals across what is now Behring Strait. It is probable, even, that the Tertiary epoch, as it witnessed the first appearance of man, saw his first wanderings in North America. He, too, came from Asia by way of the north and Behring Strait. Evolution had performed sur- prising work in the mean while with one branch of the human family, members of which, landing from Scandinavian or Spanish ships, met, upon American soil, the descendants of a migration from Asia to America in a former geological period, and to the east ! At the close of this Tertiary period of the earth's history, cold and snow and ice set in ; the long winter of the ages made its appearance in the shape of the Glacial epoch. The circumpolar moths, whose more humble fortunes we must be content here alone to follow, were forced south- ward gradually by the change in climate which gathered its frigid strength in the north. The European, Asiatic, and American faunae then became separated, the latter the most completely, and by barriers both of ice and ocean. The American species of moths, which for- merly lived upon the shores of the Arctic Ocean, were gradually forced down, year by year, until they reached Mexico, or the elevated por- tions of the Southern States. When the glaciers subsided, and the floods of ice which had submerged the continents gradually melted and slowly drained away, the moths, much changed by the long con- flict, also retraced their steps northward. As marks of the retreat and advance, colonies of moths were left on the mountains to tell of the flood. At this time our " Western clawed cutworm" ( Copimamcstra occidenta) had been long separated from its present European broth- ers, and the differences by which we now recognize the two species as distinct had become slowly established through a long series of suc- ceeding generations. What miles of land and sea separate the two to-day ! The descendants of a common circumpolar species find them- selves partly in Germany, partly in Arizona, and the Southwestern ter- ritory of the United States ! Let us turn back to the other theory, that of a submerged Atlantic Continent. Whatever may be finally proved from geology as to the existence of such an Atlantic bridge, it is clear that the myth of the Atlantis must be separated from such facts, as being of much more recent origin. Primitive man existed reons before the notions which were worked into the poetic and semi-historical myth of the Hesperides and Atlantidcs. The setting sun was followed by human eyes for un- told ages, as it bathed itself in the golden flush of evening, and was MOTHS AND MOTH-CATCHERS. 38 1 at last whelmed by the waters which were held to surround the sup- posed circular flat earth. The sun was the golden apple of the gar- den of the Hesperides, the Golden Fleece after which Jason sailed. The poet transformed the primitive notions into charming myths, which probably had their origin from the observation of low-lying clouds floating, like islands, in a sun-flushed western sky. In this region of imagination and romance it is, perhaps, better — at any rate, it is excusable — to abandon prose and take to verse. So we shall quote a modern rhymer for the explanation of " the Atlantis " : The western sky is all ablaze, And, floating on that golden sea, The clouds, like islands in a maze, Blest dwelling-places seem to be. When first this sight was viewed by man, He thought the earth was flat, not round; That all about its rim there ran An ocean which the land did bound. The poet in those early days Immortalized the sun-flushed seas; He peopled those far slopes and bays, And called the isles Atlantides. And so the legend grew until The clouds in evening's dreamy light, "With which the poet showed his skill, Had vanished from the mental sight ; Instead, the story true appeared, And every sailor did his best, "While straight from port the vessels steered For those far islands in the west. But none returned : of all who went, Who sight of those fair islands caught, Through the white waves the tempest sent The barks which shattered home were brought. o* And some returned no more — but these "Were fabled to have reached the strand, "Where, anchored in luxurious ease, Their ships will never leave the land. The crews lie on these sunny slopes, Purple with fruit, with vintage blest ; The ships are held by flowery ropes In sleepy bays content to rest. The poet steps into his boat, The sunset makes his starting fair ; Through the long night with Death he'll float, And in the morning he'll be there. 3S2 THE POPULAR SCIENCE MONTHLY. The study of the geographical distribution of moths has led us a long way back in the history of our own race, to that East whence art and science sprang. There is only one other fact to be briefly men- tioned here, and that is the discovery by Louis Agassiz, who accom- plished so much toward an understanding of our entire fauna, of a tropical colony of moths inhabiting the southern extremity of the Peninsula of Florida. I have examined the specimens brought thence, now in the Museum at Cambridge. Standing in the way of the south winds and the Gulf Stream, Florida receives constant accessions to its tropical colony of insects. Not a few of the Florida moths seem to have changed a little, and the probability is that here also we may have to do with descendants of a very ancient colonization. Our con- tinent, in fact, has harbored many immigrants besides the Pilgrim Fathers, who are distinguished among these by their greater impor- tance, and the results of their adventurous voyage. The celebrated receipt of Mrs. Glass, which is of such general ap- plication and has served so many literary purposes, must be employed before we can place our specimens of moths in the cabinet. And, indeed, everything depends upon the catching of them, and their ap- pearance after being caught. The scales and the little fine fringes which edge the wings are but delicately fastened to the membrane of the wing itself, and are lost with the lightest rubbing. Some species can never be captured on the wing in a really perfect condition. When the "bee-hawks" {Hemaris sp.) emerge from the chrysalis, there is a dusting of fine scales over the glassy portions of the wings, which is scattered by the first fluttering flight of the insect : " Like gold motes in the air it flies." Again, several moths are ornamented with patches of looser and bright-colored scales which are readily lost, the specimens still appear- ing fresh after they have vanished. Thus the " dark - red under- whig " ( Catocala cara) has the fore-wings adorned with spots of a greenish hue when it leaves the pupa, but they are apt to fall and the wings then appear all of a dark-brown. Not knowing this, the fresh specimens have been described as a new variety, by an enterprising and unfortunately somewhat critical writer, under the name Carlssima. We have the choice of pursuing our entomological prey in each of its stages of growth — of eggs, caterpillar, chrysalis, or moth. If we gather them in either of the first three states, we have to nurse them until they are brought to the last, and, since in this way we can always obtain bright examples, it is much preferred by moth-fanciers. It is, indeed, the only way to obtain adequate information about these insects, and, as they are usually brought through them all with less difficulty than the other insects in captivity, the breeding of moths becomes an alluring and profitable pursuit. Egg-hunting is the least remunerating way of procuring moths, MOTHS AND MOTH-CATCHERS. 383 from the difficulty of detecting the little objects, like pins' heads, upon the leaves and flowers where they are laid. Eggs are usually stuck fast to the under side of the more tender leaves of the plant, though this rule is not invariable, either as to position or choice of leaf. Usu- ally the outer leaves are chosen, and by turning them up with care and running the eye over them, and especially down the midrib, the little whitish or greenish egg may be seen. It requires good eyes and much patience, but I have found the eggs of about twenty species in this way : those of the "bee -hawk" on honeysuckle, of the "Cecropia" on apple and lilac bushes, the "white-lined-hawk" on purslane, etc. The " lackey-moths " ( Clisiocampa) and the " deer-moths " (Hemi- leuca) lay their eggs in circular patches around the smaller branches of fruit and oak trees. The eggs are found sometimes to have been stung by a little clear-winged fly, and out of these, instead of the expected caterpillar, only the tiny but full-grown parasite escapes. The rearing of larvos or caterpillars may be conducted on a variety of plans. I have found an upright box, with glass in front, and per- forated zinc for the sides, or fine wire netting and a solid door at back, by which the fresh food is introduced, very serviceable. A drawer at bottom is filled with fine washed sand, over which is placed a layer of garden-mold, and then a covering of moss. The food is placed in short water-bottles, to keep it fresh, and the caterpillars are placed on these. But, when a boy, I reared many species in an empty butter- tub, covered by common gauze. Almost all caterpillars may be han- dled with impunity. Some of them are ferocious-looking enough to inspire a fear of their biting powers, but they are unable to hurt us in this way. The caterpillars of the " hawk-moths " have a formidable- looking horn on the last segment or ring of the body. I have noticed that inexperienced persons often mistake the position of this horn ; they regard it as being in front, whereas it is attached to the tail-end of the larva. There is nothing " poisonous " about any of these cater- pillars, but two kinds cause a painful irritation to the skin when touched with the hand, by means of the fine hairs which are thus forced into the pores, and, the tips breaking off, cause fever and pain as from a bee-sting. These two are the odd-looking caterpillar of the "brown hag-moth" [Empretia stimulea), and the delicate-green caterpillar, with pink and white stripe on the side, of the " corn em- peror" (Hyperchivia so). Other hairy caterpillars may also produce more or less discomfort when handled, but the frightful stories which circulate in the newspapers from time to time, of people being stung to death by the caterpillars they chanced upon, are all false. Caterpil- lars can not sting, for the simple reason that they have nothing to sting with, and when an injury of this kind has been really inflicted it will be found to have been occasioned by something other than a caterpillar. Hunting for caterpillars is attended usually by more success than the seeking for eggs of moths. One can readily detect the presence of 3 34 THE POPULAR SCIENCE MONTHLY. these often unwelcome visitors by the damage they do to the treas- ures of the gardener and farmer. Many kinds feed in clusters, and make nests into ■which they retire in the daytime, separating usually before full grown and to make their cocoons. The larger species are all solitary, and some are the most beautiful objects one can wish to see. The caterpillar of the " imperial moth," which may be found on the horse-chestnut, tulip, and gum trees in Central Park every Sep- tember, when it is full grown, is a thick, green worm, as long as the thumb, with four beautifully notched horns on the back, behind the head. Delicate hairs adorn the body, and the fleshy feet behind are ornamented by a design in black-and-white, looking like bead-work, and as if the creature wore Indian moccasins. In April and May wre may find the larvae of species which pass the winter in that state. One of our handsomest caterpillars is that of the "great Indian moth" (Ec- pautheria scribonia), black, studded with bristles and with the inci- sions of the rings of the body marked in scarlet. I have fancied that this caterpillar is the one noted by the Indians, and sung of by Long- fellow in " Hiawatha." It is very interesting, no matter what the species is, to watch it through all its changes, and be rewarded finally by the moth disclos- ing all its fresh beauties before our eyes, as it hangs on the side of the breeding-cage. The caterpillars of the "hawk-moths," and many " owlet-moths," enter the ground to pupate ; and for this purpose the sand and soil in the bottom of the breeding-cage must not be kept too dry, nor suffered to become hard. Those which do not go into the ground will transform within cocoons spun among the moss, or on the sides of the breeding-cage. To collect the perfect moths, an empty quinine-bottle must be pre- pared by putting a few small lumps of cyanide of potassium on the bottom, and pouring on sufficient plaster of Paris to cover them per- fectly. When the plaster is set, the fumes of the decomposing cya- nide penetrate through the plaster, and the moth introduced into the bottle is almost instantly killed. Poison-bottles, so prepared, are in- dispensable to the collector, and they can be recommended on account of the speedy and probably painless death which they inflict. The objection to entomology is its apparent cruelty. I think that an un- necessary number of specimens are sometimes killed by the enthusi- astic collector, but, after a little, this fault will be corrected by reflec- tion and experience. When we recollect that insects are the main store of food to numberless birds and animals, besides falling a prey to each other, so that the greater proportion meet a violent death in any case, the comparatively small number which fall a sacrifice to the pleasure of the collector, or supply the studies of scientists, can not in reason be objected to. Our aesthetic pleasures are increased by the contemplation of the lovely colors and delicate patterns which adorn the wings of moths. MOTHS AND MOTH-CATCHERS. 385 That man is feral, and a hunter by nature, is an obvious reflection, even when we step into the shop of an entomologist, such as Cooke's, in London. Nets, traps, and " fearsome gins " of all sorts and sizes meet the eye. Boxes, pins, dark-lanterns, in fact an array of imple- ments too numerous to mention, are there displayed, and, whether we go a-hunting for game or for moths, the ingenuity of man has in- vented a large quantity of apparatus, by which the result may be obtained with the least exertion and the greatest certainty. Simplicity here as elsewhere is, after all, to be commended. A small folding-net which may be carried in the breast-pocket and afterward screwed to the end of a walking-cane, a poison-bottle, and a couple of boxes which may all be carried in the coat-pocket, are a sufficient outfit, and one with which great results in the moth line can be reached. The box for caterpillars should be of tin, and care must be exercised not to place too many together, since some kinds have strong cannibalistic tenden- cies and may devour each other before we get them safely home. But not only by day are moths captured. They fly readily to light in the evening, and the best results are obtained by spreading a bait, made of beer and molasses, with a paint-brush, on the trunks of trees stand- ing free. In the spring and early summer this method of catching moths may be practiced with almost the certainty of taking many rarities. After this means the best plan is to watch the flowers which the moths frequent in the evening in search of natural sweets, and in which occupation we may fatally surprise them. Having caught our moth in one way or another, it must be pinned and set, before placing it in the cabinet. In America the long German pins are used, especially manufactured for entomological purposes. The moth must be pinned directly through the center of the thorax, taking care to displace the scales as little as possible. Setting-boards are easily made by fastening two strips of soft pine-wood upon a thin board, near enough together to admit of the free passing of the body of the moth between them. They must be of several sizes, to corre- spond with the breadth of wing of the moths, which must be pinned with the body resting in the groove and the wings lying flat upon the strips. The board may be ruled across with lead-pencil, at different intervals, the lines serving as a guide to get the wings straight. With a bristle fastened to the end of a little stick, the front wings should be carried forward until their lower margin is about parallel with the hind edge of the thorax. They may be held in position by small three-cornered cardboard braces till all the wings are evenly placed, and then fastened down by strips of smooth paper, kept tightly in place by pins above and below the wings. It takes from a few days to a fortnight to properly dry the moths so that they can be placed in the cabinet. Various and multiple are the store-boxes, implements, and "traps11 of a moth-catcher. To describe them all would take a moderate-sized vol. xxvii. — 25 386 ' THE POPULAR SCIENCE MONTHLY. hand-book. My experience is, that simplicity is the most necessary guide for the collector, whether in the field or closet. A few tools and some cork-lined boxes will accomplish a great deal in the hands of an expert, while the expensive paraphernalia of the novice will fail of adequate result. As a rule, the most pleasure and information are yielded to the student who gradually increases his stores from his own catching, who follows the moths into their retreats, and by his indus- try and pertinacity compels Nature to yield to him a measure of her secrets. Long ago I remember catching moths one summer night in the country, back of Newburg, on the Hudson. What a lovely and per- fect night it was ! A sheen lay over the grass, and the field-daisies stood tall and pale and spectral in the moonlight. Their white flowers looked like silver crowns, waiting for some love-sick damsel to pluck and gather her fate from the number of their petals. They stood in silver and gold, without envying the yellow and brown daisies of the meadows which were hardly open yet. The air was traversed by leather-winged bats, also out after insects, and I felt convicted by being in their company. A pale-green moon -moth fluttered by the skirt of the dark wood, the long " tails " to her wings trailing like the court-dress of a queen. I stayed my hand and let her sweep by, hop- ing that those marauding bats might not espy her as she floated in the night-air, heavy with the scent of roses. For aught I saw, she escaped them, and the peril of having her white body devoured, her green wings clipped from her shoulders, falling idly, like the petals of dying flowers, upon the ground. Painters have not yet learned all they can from the coloring of moths. Some moths are pale-pink and yellow, only these two colors, reminding one of apple-blossoms and yellow moonlight. I saw a panel of C. Colman's once, for the contrast of colors of which it seemed he must have studied the wings of moths. As the musician can use the songs of birds, so the painter may copy the colors of the moths for our greater pleasure and his own benefit. A great deal may be said of the unconscious schooling we get from Nature. " All sorts and conditions of men " and not a few talented and ac- complished women are among the American students and collectors of moths. Before the last quarter of a century, those who interested themselves in America with this department of our fauna were few, and those who published the results of their investigations might be counted on the fingers of one hand. Harris in Massachusetts, Fitch in New York, Kirtland in Ohio, Gosse in Canada, were the best known. Thomas Say, of Philadelphia, published two species in his "American Entomology." But since that time, Professor Packard, Professor Fer- nald, Mr. Henry Edwards, Mr. F. Pepper, Mr. Lintner, and a number of talented writers, have become familiar names to those interested in the subject in the pages of its literature. The " New York Entomo- MOTHS AND MOTH-CATCHERS. 387 logical Club" publishes a monthly magazine, entirely devoted to Lepidoptera. The Buffalo Society of Natural Sciences has issued three handsome volumes chiefly devoted to studies on our moths. In Cam- bridge, Avhere Harris lived and studied, a very useful journal — " Psy. che " — appears, while in London, Canada, Mr. Saunders edits " The Canadian Entomologist " in monthly parts. The various State ento- mologists publish yearly reports, and the Department of the Interior has published valuable monographs and papers relating to our moths in the publications of the geological survey. The great work which has been done in the United States in science has helped also the increase of information upon this comparatively small branch of natural his- tory. I should have mentioned the ladies first, but it is not out of politeness that the conscientious historian records the services to sci- ence of Mrs. Eliza Bridgham, of New York ; Mrs. C. H. Fernald, of Orono, Maine ; and Miss Mary Murtfeldt, of St. Louis, Missouri. Mrs. Bridgham's extensive collection, commenced under the eye of Agassiz himself, is a model of useful collecting for scientific purposes. The species are not represented by single individuals, but the varieties of each species, and a sufficient number of duplicates to allow of the study of the structure and changes, are all carefully placed and la- beled. Years of patient and careful toil have their reward in the most interesting local collection, from a scientific stand-point, I have yet seen. In Europe our moths have been described and studied by two French scientists, MM. Boisduval and Guenie. In Germany, Professor Zeller and Dr. Speyer, together with Herr Moeschler and the lamented and talented Viennese lepidopterist Julius Lederer, have published in- teresting studies upon our North American fauna. In England, the late Mr. Walker accomplished less satisfactory work in the precincts of the British Museum, and is now succeeded by Mr. Arthur G. But- ler, whose work merits all praise. But our best incentive to the study of our moths has been afforded by the example of Lord Walsingham. It is ten years ago since his lordship visited the United States, where, unlike many of his countrymen who come to hunt buffalo, he went West to hunt moths. Lord Walsingham visited California and Ore- gon, and camped out like a true hunter. While his companions took the rifle, he handled the entomological net, and to such good effect that science has been the gainer by hundreds of new species, and a much clearer general knowledge of the subject than before existed. The delicate operation of setting his tiny captures, Lord Walsingham accomplished successfully even on horseback, as the camp was shifted from place to place — quite a feat, when it is recollected that the tiny specimens, many not a quarter of an inch in expanse of wing, require a steady hand and the most favorable conditions to be successfully prepared for the cabinet. This memorable trip of Lord Walsingham's had the result of directing the attention of our collectors to the rich- 388 THE POPULAR SCIENCE MONTHLY. ness of "Western fields for moth-catching. Their cabinets soon pre- sented new "beauties," vying with Indian and Brazilian species in varied colors and far surpassing them in general interest. I said that " all sorts and conditions of men " were among those interested in forming collections of moths, and it may be inferred that there are queer specimens among the owners of the cabinets as well as in the drawers of the cabinets themselves. Moth-catching is a hobby, and, like other hobbies, it depends upon how it is ridden to pronounce upon its value from a social or scientific point of view. Some collectors amass their material from an apparent simple satisfac- tion in possessing rare or odd specimens. They have no appreciation of the bearing which the subject has upon general science, and no higher artistic interest in their possessions than the one that they have some- thing no one else has got, and which it is difficult to obtain. A sort of purposeless mania seems to fall upon many of them, and they might as well get together a lot of old bottles or stones as moths. They deceive each other as to the locality for their rarities. I have even heard of one rabid collector, now happily deceased, who destroyed every specimen he had or could buy up of a certain rare exotic species, except one pair in his own collection, so that he could say he was the only one who had it ! Another openly stated in an advertisement that he " coveted " certain specimens, which he offered to buy ; thus, proba- bly unintentionally, using a word which expressed his condition ex- actly, and in this way succeeding in breaking a commandment and exposing his state of mind at the same time. While the " brethren of the net," as the moth-catchers are fond of styling themselves, are, generally speaking, a friendly and useful class, they necessarily include many who follow the occupation, but are yet not truly of them. From such the gentler student will soon turn away, sometimes not detecting them until he has suffered in purse and cabinet. Like other " confidence operators," they generally take in uninformed and young collectors, whose rarities are speedily trans- ferred out of their keeping by the false statements and industrious letter-writing of these moth-poachers. They are the dark side of a picture which would be otherwise too bright and happy. Among the figures of moth-catchers which have crossed my own path, I finally recall that of a kindly old gentleman, now no more, who for many years was a visitor to my humble study. His beardless, wrinkled face, framed in gray hair, had ever such a good and serene expression as betokened a mind which had caught its serenity from the countenance of Nature herself. I visited him in turn and not un- frequently, and I remember on one particular occasion that he showed me a new capture which he had made on Long Island, a new butterfly, not then described in the books. As he took it from the box and placed it on the table before him, pinned, dried, and set, in all its beauty, a little dog, which was his pet and companion, sprang at his HYGIENE OF THE AGED. 389 knee and with one blow of his paw broke the butterfly. To the old gentleman it was as to Sir Isaac Newton — the loss was great, and the shock must have been intense. Although I had hardly seen the speci- men, I was profoundly affected by the mischance. But he neither struck the dog nor spoke loudly. With a trembling hand and flushed face he set to work at once to gather up carefully the disjointed wings of his specimen, which was happily accomplished, and, with a little gum and much patient dexterity, the damage which seemed at first irreparable was remedied. It taught me a lesson I have never since forgotten. The butterfly was the rare Papilio Calverleyi, of which up to the present time but one other specimen has been found. I have now new faith in that old story, from having witnessed a similar oc- currence, and fresh belief in the goodness of that human nature which science and its pursuit often tend to strengthen and confirm. -+*+- HYGIENE OF THE AGED. By L. H. WATSON, M. D. DIFFERENT epochs in life are marked by the frequency or in- frequency of certain morbid phenomena constituting that depart- ure from the normal standard of health which we denominate disease. What is life ? is the unanswerable question the human race has ever sought to solve. Bichat called it "the sum of the functions by which death is resisted." Physiologists of the present day offer little more that is satisfactory in their definitions, calling it " the aggregate of the phenomena peculiar to living organisms." The inscrutable mystery which surrounds the principle of vitality renders any attempt at definition illogical and unsatisfactory. We have to deal with the phenomena of life, and the functions through which these phenomena are manifested. In the child we have an exuberance of life. Man- hood is the period of repose ; waste and repair seem to neutralize each other ; and calmness, deliberation, and quietude prevail. With old age come disturbance, waste without repair, destruction without building up, action without reaction, decay and death. These phases of animal life are constantly repeating themselves. In discussing the diseases of old age, we have to deal with the phenomena of life, the perversion of functions which have hitherto counterbalanced each other. The prime of manhood and stability is passed ; internal resist- ance now fails to maintain itself against external force. Nutritive action does not respond to the demand to renew effete material. The equilibrium being destroyed, decay and the products of decomposition become the most important factors in the study of the diseases which now threaten to disintegrate this hitherto self-sustaining system. 3Q0 THE POPULAR SCIENCE MONTHLY. It will easily be seen that the diseases which disturb the formerly evenly balanced organism tend toward what pathologists call destruc- tive metamorphosis. Blood-changes, tissue-changes, and secretory changes, are subjecting us to constantly varying standards of health. How to maintain the equipoise as long as possible, and prevent the too rapid decline of the vital forces, as well as to suggest measures — when care and forethought can ward off the blow — is the province of the thoughtful medical man. Threescore years and ten should certainly be reached by most of those who attain adult age, provided no inherited taint weakens the vital forces. It is difficult to determine the exact period of life at which the decline commences. In fact, there can be no absolute stand- ard from which we can predict with unvarying certainty the gradual failure of the physical powers. Some seem to inherit a vitality which almost defies the ravages of time ; but, although they are apparently in the full vigor of life, close scrutiny rarely fails to detect the fact that the scale is tipping downward. We do not grow old in a night, although we often make the remark that So-and-so has grown ten years older since the occurrence of some great grief, or some disas- trous reverse in business. The eye-sight gets poorer, the hair and beard grayer and thinner ; the form is more bent, the walk more uncertain, the circus senilis appears in the cornea. After all, this is not old age; these are all warnings, but the heart is still warm, the eye still bright, the muscles still firm. The world looks as fair and invit- ing as it did in early manhood or womanhood — a little larger print to read, a smoother road to walk on, a few more flannels at night, and a little less labor during the day, with perhaps a greater disposition toward quiet, a greater fondness for home-life, and a disinclination to encourage the enthusiasms which time and experience have so often proved to them to be illusive. We are to consider the physiological and pathological conditions arising during this epoch of life. Many of these are characteristic, and do not earlier manifest themselves. We have many works upon the diseases of children and adult life, but almost none pertaiuing to the diseases incident to age. And yet they are peculiar. The pneu- monia of a child is not the pneumonia of an aged person. Slight ailments, unobserved or disregarded in the adult, become positive dis- ease in advanced life. Our acute fevers, inflammations, fluxes, etc., are not met with among the aged. Congestions, chronic inflammations, tumors of the brain, paralysis, rupture of blood-vessels, enlargement of the heai-t, chronic bronchial affections, dropsical effusions, indigestion, diseases of kidneys and bladder, especially the latter, cancers, etc., are what the physician is most often called upon to prescribe for in old people. Aside from actual disease, the conduct of the life of elderly persons is to be studied and observed. Ordinarily old age brings with it, or should, HYGIENE OF THE AGED. 391 a certain degree of leisure and immunity from the distressing anxie- ties which vex and worry the lives of men actively engaged in busi- ness. The danger of sickness from exposure, as far as the liability to exposure is concerned, and the danger arising from accidents are lessened ; old people are careful, and warily thrust themselves into danger. Calmness, quietness, and a regular habit of life, succeed to confusion, activity, and an indulgent and irregular method of living. Life wanes, the descent is easy and gradual, a peg is lost here and a prop there, the sympathies become blunted, the intellect chilled, the senses lose their acuteness, and "the play is played out." What more delightful spectacle than an aged person in full possession of all his faculties, enjoying life with the zest of manhood's prime, appreciative of the pleasures of the table, the society of friends, the charm of music, and the intellectual feast that a good book presents to him ! Hufeland, in his " Art of prolonging Life," advises old people to eat sparingly. There is a great difference between a "gourmet" or "gourmand" and a glutton. The pleasures of eating dependent upon the sense of taste, when eye-sight and hearing are daily becoming more and more impaired, the possession of leisure in which to cultivate their gastronomic talents, as well as the quiet necessary for the performance of the digestive act, combined with the necessity for careful nourish- ment, prohibit old people from yielding to any mistaken notion that, because they are old, food is of little consequence to them, and that the ordinary rules governing assimilation and nutrition do not hold in their case. A great deal of the immunity of old people from sickness will de- pend upon their power of digestion and assimilation. Food and drink should be partaken of sparingly, and at proper intervals : an overloaded stomach, or a stomach filled with badly cooked food, or food taken at an improper time, will occasion much distress to an old person. At the same time, it may lay the founda- tion for disease which will cut short a hitherto robust old age. If actual pain and danger do not follow this gorging, it will prob- ably entail loss of sleep, and consequent exhaustion, all of which we seek to shield the old from, as we do the child. In the normal act of digestion, the consciousness of that act is wanting. Most persons engaged in active life fail to give the proper amount of time to eating and digestion ; for this natural and physio- logical action to be performed with the ease and perfection of detail which Nature, in her arrangement of the means for such an end, in- tended, deliberation must accompany the eating, and rest of mind and . body the digestion of food. Haste when eating, and activity, bodily or mental, during the digestive process, are fatal to the object for which food is taken. It is only in old age (I refer particularly to America), now, that that leisure which is indispensable to the proper perform- ance of digestion is obtained, and yet, when, after years of toil, we 392 THE POPULAR SCIENCE MONTHLY. perchance through the inheritance of a resisting power which has enabled us to arrive at sixty years of age, and upward, find the time to rest, our teeth are gone, our stomach, from constant action, is unable to act with that promptness and energy which early in life enabled us to digest food on the run, as it were. Then the physician is called upon to encourage, stimulate, and prop up by his art, Na- ture's waning forces. The manifestations of dyspepsia in the aged do not vary materi- ally from those of adults, but the causes are somewhat different ; the treatment is conceived on a plan based on the age and life-long habits of the patient. An aged stomach is not an active stomach. Atony characterizes its functional action. Acid digestion, gastric catarrh, and flatulency, are the leading forms of dyspepsia of the aged. Old people have not in general what we call a healthy appetite. One well-known writer has said that they eat because no other interesting occupation is afforded their senses. This may be true of the very aged, and it undoubtedly is a fact that most people of eighty years and upward find as much pleasure in eating as in almost any other occupation left them. The appetite is often lost when no disease can be detected. There is loss of the sense of taste, and even several days without food does not provoke hunger. In another form, the breath is somewhat offensive, the tongue furred, when in the former case it was clean. Fisher tells us that, if this continues, it leads to senile marasmus or atrophy of the aged. Some old people suffer from a difficulty in swallowing, which seems to be the result of a partial paralysis of the throat ; the pharynx does not respond to the stimulus of food as it passes over it. Solids pass more easily than liquids. Deglutition is more difficult in an upright than in a horizontal position. Fisher speaks of the case of a man sixty years of age who swallowed soft and mucilaginous preparations with great difficulty, but warm food, salty or irritating substances gave little trouble. Day has noticed the same fact, and observes that irritating or highly seasoned foods were the only ones swallowed easily. Canstatt thinks that the abuse of tea and coffee leads to the development of this state, which he says is very common in Holland. Old people are subject to accumulations of gas in the intestinal tract, which not only occasion distress from over-distention of the stomach, causing pressure upward upon the diaphragm, and conse- quent interference with the heart's action, especially when lying down, but also from its passage downward into the bowels. Diarrhoea is one of the consequences of dyspepsia, and it is not unusual to find old people who have several movements of the bowels daily, without any of the exhaustion attendant upon ordinary diar- rhoeas. Another remarkable fact is, that we find, even in very old people, a diarrhoea which would naturally seem to weaken and pros- trate even a strong man, but the effects of which are not noticed until HYGIENE OF THE AGED. m suddenly we learn that death has taken place. Overfeeding is a fre- quent cause of these senile diarrhcEas. The pressure of undigested food in the intestinal canal is followed by a sudden purging, without pain, hut exceedingly rebellious and difficult to conquer. Before treating of the methods of cure for dyspepsia and its accompaniments, such as loss of appetite, difficulty in swallowing, flatuence, constipa- tion, etc., there remains to be studied the food suitable for old people, the quantity to be eaten, and the time for eating. It would be useless to present a dietary list to which one should be strictly confined. A long life of indulgence in eating and drink- ing, as well as diversity of taste, would preclude any attempt at regu- lating the diet of healthy elderly people. To those who have arrived at an advanced age without any form of indigestion, I would suggest a cup of coffee and a slice of dry toast before rising in the morning. The reason why this should be served while one is yet in bed is, that very old people, even when perfectly well, are often subject to a slight faintness and nervous tremor before rising, and the exertion necessary to dress often leaves them too faint to eat. It takes but a few mo- ments to prepare it, and, as old people like to rise early, it is usually an hour or two before the family are prepared for the morning meal. A light luncheon at noon, and dinner not later than five or six o'clock. If the dinner is taken at noon, and supper at six o'clock, it will be found to suit the habits of the aged better in one way, as old people love to retire early. In most countries, among civilized nations, the practice of crowding three meals into the twelve hours or more of daylight has grown to be such a habit that it seems a heresy to sug- gest eating when hungry, day or night ; nevertheless, I would suggest to the healthy and not too aged person to forget the " bugbear " of "not eating before retiring," which compels many a person — otherwise disposed — to pass ten or twelve hours with the stomach in a collapsed condition, while during the other twelve it is constantly distended with food. I would say to the aged, eat sparingly and eat frequently. Let your food be light, and easily digestible, but eat when hungry, whether it be twelve o'clock at noon or twelve o'clock at night. Aged people are light sleepers, and often wake up during the night with an intense craving for food, and a good plan is to have a cup of bouillon and a cracker on a stand near the bed. The broth can be readily heat- ed by an alcohol lamp in five minutes. This simple habit will often procure hours of uninterrupted slumber, which would otherwise be passed in restless longing for daylight and breakfast. I have said, eat sparingly and frequently ; eat sparingly, because the digestive action is not so strong as in earlier life, nor is the demand for large quantities of food so urgent. Eat frequently, for several reasons. The digestive organs are not then burdened with large quan- tities of food, and dispose of it with greater ease. A moderate amount of food in the stomach gives a feeling of comfort and quiet to a person 394 THE POPULAR SCIENCE MONTHLY. whose sole occupation may be a little reading or knitting, or even nothing at all, when extreme age is reached. The kind of food to be eaten varies with the condition : if the old person needs building up, the more nutritive foods, that is, those con- taining the greatest amount of nourishment to a given volume, the greatest proportion of assimilative matter ; if, on the contrary, it is necessary to encourage the digestive action, we select stimulating food. In this connection I shall quote from an eminent French authority : " As age advances, not only is one able to bear with impunity food which is piquant, pungent, and more exciting, but the use of these latter foods is necessary to the physiological conditions acquired by the 'organs of digestion.' "This alimentation becomes especially necessary to individuals whom residence in great cities, sedentary life, and confining work separate in a great measure from the natural conditions of life, found in free air and bodily exercise." With regard to the use of wines or liquor by the aged, I would say, if there is a proper time in the life of a man when he should use stimulating drinks, that time is when he has arrived at a good old age. A glass of sherry or burgundy during dinner often aids digestion wonderfully. When the tongue is pale, and the desire for food absent, a " nip " of brandy will stimulate the stomach into secreting properly. This condition of atony or sluggishness of action is not at all unusual. A glass of milk-punch at night often goes, as a very good and exceed- ingly temperate old lady once said to me, "to the right spot." Coffee is a natural drink for the aged. Its mildly stimulating, soothing quali- ties directly indicate it as a beverage for the old. Gasparin tells us that " coffee has the property of rendering the elements of the body more stable, and thus, if not affording nourishment, it diminishes the waste going on." The origin of many dyspepsias in the old will be found in the lack of the proper means for the complete mastication of their food. The loss of their teeth, and the neglect to replace that loss with artificial ones until a dyspepsia is established, will often entail a long train of ills. A set of false teeth will sometimes remove dyspeptic troubles of long standing. The teeth with metal plates (platinum or gold), al- though more expensive than rubber or celluloid, are to be preferred. Mastication must be well performed even if the food is not very solid. The one golden rule is to eat slowly. Some old people have idiosyncrasies about certain foods, which must not be overlooked. Milk is one of the most easily digested of foods, on account of its various constituents, and can be taken when nothing else is permissible. Eggs, soft-boiled or raw, are easily digest- ed. Oysters, fish, and lamb, follow in about the order named. Beef, mutton, and fowls, and wheaten bread, occupy about the same time in digestion. I have met with two forms of dyspepsia more frequently THE OLDEST AIR-BREATHERS. 395 than any others in prescribing for old people — the acid form, where there is an excess of acid found in the stomach, and the atonic form, where there is sluggish action of the mucous membrane of the stom- ach, and the time for digestion is greatly lengthened. In acid dyspep- sia, Dr. Ringer recommends the use of glycerine, stating that an old gentleman, upon learning that glycerine prevented milk from turning sour, concluded that it would be just the thing to prevent " himself from turning sour." I have used glycerine combined with charcoal with considerable success in remedying this form of dyspepsia. Dilute nitro-muriatic acid, a half-teaspoonful in a claret-glass of water, immediately after meals, breaking up the weaker acids and affording the natural acids of the stomach, is an exceedingly useful remedy. The atonic form of dyspepsia, combined with loss of appe- tite, requires quite a different treatment. The stomach is feeble, and needs stimulating ; two or three grains of capsicum with one half- grain of aloes in a capsule will excite it to action ; the constipation which often accompanies this form will be obviated. When there are accumulations of gas, charcoal tablets au hour or two after meals generally give great relief ; but it is not a good plan to keep up their use permanently, as it tends somewhat toward constipation. Electric- ity is the great tonic for these debilitated, relaxed stomachs. The sympathetic nervous system is rehabilitated, and the most marvelous effects are often produced. The apathetic condition of the intestinal track is dissipated, the liver pours out its bile, and life seems to move on again. Alkalies taken before meals stimulate the flow of the gas- tric juices. Slight fatigue often spoils the appetite, and lowers the digestive power. Nothing so securely revives this as a glass of wine before meals. While small quantities of alcohol aid digestion, larger quantities retard it and encourage gastric catarrh. The quantity of wine or brandy must be small when taken for this purpose. •»♦» THE OLDEST AIR-BREATHERS. WE alluded in the March number of the " Monthly," to the fossil scorpions recently discovered in the Upper Silurian formations of Sweden and Scotland, recognizing them as the most ancient specimens of land or air-breathing animals yet found. The subject has since gained a new interest through the discovery of a still older fossil of an insect, and by these our knowledge of the land of the earth and of some of its inhabitants is carried back by at least two immense geological periods. We therefore give place to a fuller account of the discoveries, with portraits of these newly found oldest inhabitants of the solid part of the globe, collating the facts and borrowing the illustrations from 396 THE POPULAR SCIENCE MONTHLY. the French and English scientific journals. Scorpions had already been found quite abundantly in the lowest carboniferous strata. The first palaeozoic specimen that came to light ( Cyclophthalmus senior) was found in the coal formation of Chombe, Bohemia, and was de- scribed by Count Sternberg in 1835. Three years later another scor- pion (31icrolabis) was described from the same locality. The next discoveries were American, and were made in the coal-measures of Illinois, of two genera which Meek and Worthen described as Eoscor- pius (dawn-scorpion) and Mazonia (from Mazon Creek, where they were found). In 1873 Dr. Henry Woodward showed that Eoscorpius remains occurred in the coal-measures of England and in the carbon- iferous limestone of Scotland ; and in 1881 Mr. Benjamin N. Peach described a considerable number of scorpions which had been obtained by the officers of the Geological Survey of Scotland from the lowest carboniferous rocks of the Scottish border. In his paper, which was published in the " Transactions " of the Royal Society of Edinburgh, he pointed out the general resemblance and almost equally high or- ganization of these ancient scorpions and those of the present dajr, and expressed regret that Messrs. Meek and Worthen had given the name of Eoscorpius to their specimens, " for the dawn of the scorpion family must have been at a much earlier period, and we may hope that their remains wTill yet turn up in the Devonian and Silurian plant-beds when these come to be thoroughly searched." This prediction has been verified in the discovery of the Scotch and the Swedish Silurian fossils. The Scotch scorpion was discovered first, by Dr. Hunter, of Carluke, who obtained his specimen from Lesma- hagow, in Lanarkshire, in June, 1883 ; but the Swedish professor, Lind- strom, although a year later in discovery, anticipated him in announc- ing it and in publishing the description of his fossil. In a letter of November 24, 1884, to M. Alphonse Milne-Edwards, Professor Lindstrom says of his scorpion (Fig. 1) : " The specimen is in sufficiently good preservation, and shows the chitinous brown or yellowish-brown cuticle, very thin, compressed, and corrugated by the pressure of the superposed layers. We can distinguish the cephalo- thorax, the abdomen, with seven dorsal lamina?, and the tail, consisting of six segments or rings, the last narrowing and sharpening into the venomous dart. The sculpture of the surface, consisting of tubercles and longitudinal keels, entirely corresponds with that of living scor- pions. One of the stigmata on the right is visible, and clearly demon- strates that it must have belonged to an air-breathing animal, and the whole organization indicates that it lived on dry land." Professor Lindstrom points out, as a feature of great importance in the conforma- tion of the animal, the existence of four pairs of thoracic feet, large and pointed, resembling the feet of the embryos of several other tra- cheates and animals like the Campodea. This form of feet, he re- marks, " no longer exists in the fossil scorpions of the carboniferous THE OLDEST AIR-BREATHERS. 397 formation, the appendices belonging to which resemble those found in the scorpions of our own day." This species has been named Palce- ophoneus nuncius. The Scottish specimen (Fig. 2) is described by Mr. Peach in " Na- ture " as being about an inch and a half long, and lying on its back on the stone. " Its exposed ventral surface shows almost every ex- ternal organ that can be seen in that position, and in this way serves to supplement the evidence supplied by the Swedish specimen. As in the northern individual, the first and second pair of appendages of the 398 THE POPULAR SCIENCE MONTHLY. cephalo-thorax in the Scottish example are chelate, but the palpi are not quite so robust. The walking-limbs, though not so clumpy as in P. nuncius, also terminate in a single claw-like spike. The arrange- ment of the sternum shows a large pentagonal plate (metasternite). against which the wedge-shaped coxae of the fourth pair of walking- limbs abut. The coxae of the third pair bound the pentagonal plate along its upper margins, and meet in the mid-line of the body, where they are firmly united. The coxae of the first two pairs, as well as the bases of the palpi, are drawn aside from the center line of the body, showing that, as in recent scorpions, these alone were con- cerned in manducation, or rather the squeezing out of the juices of the prey ; from the circumstance of these being drawn aside, the medial eyes are seen pressed up through the cuticle of the gullet, and a fleshy labrum (camerostome) appears between the bases of the chilicerae. " Behind the pentagonal plate and the coxae of the hindmost limbs there succeeds a space shaped like an inverted V, where the test is thin and wrinkled in the line of the long axis of the body. It is just along this line that the trunk or abdomen most easily separates from the cephalo-thorax in recent scorpions, and it is at once apparent that the trunk in this case is as far separated from the cephalo-thorax as it can well be without being detached. Similar longitudinally wrinkled skin is seen to unite the dorsal and ventral scutes up the whole right side of the trunk. At the interior angle of the inverted V there hangs downward a narrow bifid operculum flanked on each side by the combs, which have each a broad triangular rachis set along its lower edge with the usual tooth-like filaments. The combs almost hide the first of the four ventral sclerites, which bear the breathing apparatus in recent scorpions, notwithstanding which all four of these exhibit on their right side undoubted slit-like stigmata at the usual places. The fifth ventral scute of the trunk suddenly contracts posteriorly, and to its narrow end is articulated a long tail of five joints and a poison- gland with a sting. These joints are all constructed on the same principle as those of recent scorpions, and, as the articular surfaces are more highly faceted on the dorsal than on the ventral aspect (a por- tion of the tail of the specimen lying sidewise allowing of these ob- servations), there can be no doubt that the animal was in the habit of carrying the tail over the head (so to speak), and stinging in the same manner as its recent congeners." These characters are shown in the accompanying illustration (Fig. 2), which is on the same scale as that of the figure of the Swedish example (Fig. 1), viz., about twice the natural size. The animal is supposed to have wandered to the sea-shore in search of food, and there been imbedded in marine strata. From the com- pleteness of the remains, it is evident that it can not have been car- ried far out to sea ; the rocks of the formation in which the fossil was THE OLDEST AIR-BREATHERS. 399 found abound in Eurypterids, or fossils of a crustacean allied to the king-crab. Of the recent discovery of earlier Silurian insects, we have the fol- lowing account given by M. Charles Brongniai't to the French Acad- emy of Sciences : " Fossil insects have been found in the carboniferous strata. The coal-beds of Commentry have furnished some thirteen hundred specimens, and Mr. Scudder has |H described six specimens that were found in the Devonian beds of New Brunswick ; but, until very recently, no representative of that class had been detected in any of the more ancient formations. M. Douville, a professor in the School of Mines, has shown me a piece of Middle Silurian sandstone from Jurques, Calvados, bearing a dis- tinct impression of an insect's wing (Fig. 3). The state of pres- ervation is not perfect, but we can still distinguish most of the ner- vation. The wing, which is about thirty-five millimetres long, be- longed to a blattid, an insect of the cockroach family. The hu- meral field is broad, and upon it may be seen the superior humeral vein ; the inferior humeral vein, bifur- cated at its extremity ; the vitrean or median vein, likewise divided into Fig. 3.— Fossil Scorpion, from the upper Silurian rocks of Lesmahagow, Lanarkshire, Scotland, found by Dr. Hunter, Carluke.

The remarkable feature which distinguishes this impression from the wings of all other blattids, living and fossil, is the length of the anal nervature and the scant width of the axillary held. Among the blattids of the coal period, the Prog- noblattina Fritschii (Heer) and the Gerablattina fascigera (Scudder) have a nervation a little resembling that of our Silurian wing. We propose to name this ancestor of the Blattce, Palceoblattina Douvillei, in honor of Professor Douville. " Geologists regard as identical the sandstones of May and Jurques Fig. 5.— Living Blattje, male and female (Bldbera claraziana), from Mexico. in the Calvados, and place them in the Middle Silurian, while the schists of the Island of Gottland belong to the Upper Silurian. Our blatta-wing, then, must be regarded as older than the scorpion described by Professor Lindstrom and the other similar scorpion from the Upper Silurian of Lanarkshire." Besides the engraving of the actual fossil wing in Fig. 3, we give in Fig. 4 an ideal restoration of the same ; and in Fig. 5, for com- parison, a representation of a living blatta from Mexico, the venation of whose wings nearly corresponds with that of the fossil. SKETCH OF PROFESSOR S. P. LANGLEY. 401 SKETCH OF PROFESSOR S. P. LANGLEY. By EDWAKD S. HOLDEN. I HAVE been asked to write a sketch of the life of Professor Langley, to accompany his portrait in this number of " The Popu- lar Science Monthly." Something of the life of every scholar and of every public man belongs to his audience ; while most of that personality which endears him to his friends is their private possession, not to be set forth, except within narrow limits. Professor Langley was born at Roxbury (now Boston), August 22, 1834. Like many another Boston boy, he was sent to the Boston Latin School, where Latin and Greek and little else was taught. Latin and Greek was reputed to be the sum and end of learning, and Harvard College seemed to show dim perspectives of more Latin and Greek. It was no wonder that young Langley, whose genius lay in quite another direction, should look about him, after his graduation from the school, to see if there were not some practicable way in which he could pursue those mechanical and astronomical studies that already had fascinated him. He had little inclination to enter college, and the openings in astronomy proper were very rare in those years, even rarer than now. Since he was ten years old, he had been reading and studying astronomy, making small telescopes, using these and others, with various success, but always with ardor. The practical question of how to shape his life was one that had to be solved, and a variety of causes led to his determination not to go to college, but to become a civil engineer. Here at least was a profession whose basis was mathematical, and in which mechanical tastes and acquirements would have scope. So the practice of engineering was begun ; special cir- cumstances forced him into architecture, and for some years this was his pursuit. These were dull years, mostly spent in the West, where at that time there were few opportunities to display any real ability in this special calling. There is little doubt but that the long and dreary hours spent over the drawing-table were an admirable though tedious preparation for the series of astronomical delineations which have been of so solid a use to science. But, finally, in the lack of real opportunities, archi- tecture ceased to be a profession, and became a business, a means to live simply. In 1864 Langley felt the need of some marked change in his life, and he spent the greater part of the years 1864 and 1865 in Europe. In 1865 he returned to America, then thirty years old, and found himself entirely free, for the first time in his life, to follow his own inclinations. So, at thirty, instead of twenty, we find him as one of vol. xxvii. — 26 +02 THE POPULAR SCIENCE MONTHLY. the regular assistants at the Harvard College Observatory. From this time forward he belongs to astronomy, although many an obstacle was yet to be overcome before he could freely exercise his special and high talents. After a few months at Harvard, Langley was offered the position of Professor of Mathematics at the United States Naval Academy at Annapolis. Before the war, a small observatory had been founded at Annapolis by Professor Chauvenet. It contained a six-inch equatorial, and an exquisite meridian circle, by Repsold, with which Chauvenet had already made some observations. The removal of the Academy to New- port and the resignation of Professor Chauvenet left these instruments unused, and it was Langley's first business to remount them and to place the small observatory on a working basis. The next year was an apprenticeship in the practice of astronomy. In 1867 Professor Langley was invited to become the Professor of Astronomy in the Western University of Pennsylvania (at Pittsburg), and to take charge of its observatory on one of the high hills across the river (Allegheny City). The previous history of the observatory had been a check- ered one, and its equipment was in the last degree inadequate and incomplete. It had been built in a good situation ; there was a dilapidated dwelling-house on the grounds ; the observatory building itself was there ; an equatorial of thirteen inches aperture was mounted ; but this was all. Everything was bare ; the equatorial was not provided with the necessary apparatus ; the observatory was entirely empty, except for a table and three chairs ; and the professor was expected to be active there, while at the same time he was to attend to the full duties of a chair at the college ; no assistants were provided, and the observatory had no income ! It is hardly possible to conceive a situa- tion more tantalizing and less hopeful. A way out soon suggested itself. For the prosperity of the ob- servatory some definite income was essential, and it was absolutely requisite to earn this. What has an observatory to sell, that the business men of Pittsburg — the railways, the iron-masters, the glass- founders — will buy ? Clearly, the only thing they want is the correct time. But will they pay for it ? This was what Professor Langley set himself to provide, and by 1869 the full system was in successful operation and yielding a fair income to the observatory. For some years before, certain other observatories had established more or less complete time-services (at Albany, Washington and elsewhere), but the system at Allegheny was the most complete and elaborate of any, and the first which was looked to for an adequate support of an obser- vatory. Besides regulating the public time of Pittsburg and of numerous private offices, the observatory provided the standard time for the whole system of railways centering in Pittsburg, and daily sent (auto- SKETCH OF PROFESSOR S. P. LANGLEY. 403 raatically by electricity) the beats of its standard clock over the tele- graph lines from New York and Philadelphia west as far as Cincinnati and Chicago, north to Lake Erie, and south to Washington. This system is still in full operation, and has always maintained a high character for accuracy. The United States Coast Survey organized several parties to ob- serve the total eclipses of 1869 and 1870, and Professor Langley went to Oakland, Kentucky, in 1869, as a member of the party of his friend Professor Winlock, Director of Harvard College Observatory. In 1869 his station was upon the very edge of the shadow, and the object of his observation was to determine the limit of total eclipse. In 1870 the station assigned to Professor Langley was at Xeres, in Spain, where he determined the polarization of the solar corona to be radial. During the year 1870 the affairs of the observatory began to as- sume such a shape that some time for original work in astronomy was available. The success of the time-service had created a small fund out of which the more pressing needs of instrumental equipment were provided ; and Professor Langley now began a period of the most incessant work on the minute study of the features of the sun's disk. The situation of his observatory at Pittsburg, where dense clouds of smoke and dust and dirt obscure the heavens, and the meager state of his instrumental equipment, almost forced him to take up the study of the sun, which has light enough to penetrate even a Pitts- burg fog. Fortunately, this study demanded very few auxiliary pieces of apparatus : the telescope has to be directed upon the sun, its motor- clock keeps it constantly pointed upon the same spot, and the observer has to follow, with infinite diligence and patience, the elusive details which the moments of best vision may allow him to glimpse. Two very important and rare qualifications are also necessary. The observer must be entirely unprejudiced and impartial ; recording that which he sees, whether it is expected or not, and recording nothing which he does not see, no matter how firmly he may be convinced that it ought to be visible. This is the first qualification — one of unusual mental constitution ; and the second is one of unusual manual skill. The observer must be able to delineate the most extraordinary and complex details justly and correctly. Both of these unusual qualifications Pro- fessor Langley possesses in a marked degree. His well-known and most beautiful drawing of a " Typical Sun-spot " illustrates this. This has since been copied in very many places, and it has received the very highest praises from all competent judges. Professor Langley's earliest published paper on the sun (February, 1874) may be taken as a type of his best work. It possesses that hardly-definable quality by which we become aware that it was written from a full mind. It is only fifteen pages long, yet we are not con- scious of undue brevity. One has a sense, in reading, that every state- 4°4 THE POPULAR SCIENCE MONTHLY. _____ — — - - — ,- -*-~— - - ^?^^t^-— r~ if ^^T"- ■'•*"."* — ~~*^ |;i;^" ' 'O .:■•§- :-"-4JV*lV .-^ TT.-.^'. rr^-rW Sri __S_ A Typical Sun-spot. ment of fact, or every expression of opinion, is based upon a hundred single instances like the one which is chosen, or upon a hundred con- curring judgments. It is not that you are overborne by weight but convinced by character. This most important paper came at exactly the right time. It first summarizes the works of other recent observ- ers, which, though important, had left the subject in an entirely un- satisfying condition, and then proceeds straight to the subject in hand. The minute details, both of the general solar surface and of the extraordinarily complex spots, are one by one satisfactorily and lucidly described, with indications of the physical conditions to which they are due ; and, finally, the general bearings of all this on the received solar theories are briefly set forth. We may fairly say that this paper is fundamental. It treats of a subject of which little had been accu- rately known, and it leaves this subject in a satisfactory and settled SKETCH OF PROFESSOR S. P. LANGLEY. 405 condition. Four years of labor on this subject had not failed to sug- gest many other researches. A detailed study of the distribution of the heat of the solar sur- face was begun about this time, by means of the thermopile, and was quickly rewarded by the discovery of an unknown thermo-chroic ac- tion in the sun's atmosphere, such that it transmits the light less readi- ly than the heat, owing to the difference in wave-length. An inter- esting consequence of this action is that, if, at any time, the sun's atmosphere should grow thicker, the color of the sun would tend toward red ; if thinner, then toward blue. These changes, which are quite possible, suggest interesting explanations of some of the phe- nomena of the variable stars. The glacial epochs on the earth may be connected with changes in the solar atmosphere. In 1877 we find another outcome of the series of measures of the heat from various parts of the sun's disk, and especially from the umbrae, etc., of sun-spots. The periodic changes in the spotted area of the solar disk, which had long been known, induced the inquiry whether changes in the amount of spotted surface bore any relation to changes of temperature on the earth's surface. The result of the extremely delicate measures of Professor Langley led plainly to the conclusion that the direct effect of sun-spots on terrestrial temperature is sensible ; that, when the spotted area is a maximum, the temperature is on that account lower, and the converse ; but that the total direct effects of the periodic changes in the spotted area on the earth's mean temperature are extremely small, not more than a change of three tenths of 1° C. in eleven years, and not less than one twentieth of 1° C. The indirect effects are not here con- sidered. A thermopile used in connection with the most sensitive galvanom- eters is an extremely delicate instrument ; and Allegheny Observatory now possessed a most complete outfit of this sort. But the most important and pressing questions in solar physics demanded a means of measurement of heat still more delicate. When it wras a question to measure the heat radiation from the different parts of the sun's disk, the thermopile was adequate. But if the heat from one of these parts is spread out into a heat-spectrum several feet or even yards long, it becomes necessary to devise new means of measuring the minute differences between the various parts. Such a device is the bolometer, which consists of two systems of extremely thin steel or platinum strips. Through these two systems an electric current passes. A sensitive galvanometer connected with both sys- tems keeps its needle steady when the currents are equal. If one system is now exposed to heat radiations while the other is protected from them, the temperature of the first is raised, its electric resistance is increased, and the battery-currents through the two sys- tems and the galvanometer no longer balance. The galvanometer- 4o6 THE POPULAR SCIENCE MONTHLY. needle then moves, and the amount of this motion measures the amount of heat disturbance. The sensitiveness of the instrument is from ten to thirty times greater than that of the most delicate ther- mopiles possible, and its constancy specially tits it for its work. The years 1879 and 1880 were given to perfecting this new and powerful instrument. Some of its first results were to show, by direct experi- ment, that the maximum of heat in the normal spectrum was in the orange, not the infra-red (then an interesting fact) ; and that the solar-constant,* as determined by previous methods, was decidedly too small. The most suitable methods of determining this important constant were pointed out. In 1881 Professor Langley organized an expedition to the top of Mount Whitney, in California, for the purpose of applying these new methods under the most favorable conditions. The expenses of the expedition were jointly borne by the United States Signal Service and by the private subscription of a wealthy gentleman in Pittsburg, who had now for some years taken the greatest interest in the re- searches of the observatory, and whose liberality had provided many of its instruments. His name ought to be here mentioned. He has materially aided science in the most liberal and thoughtful way ; but, against his ex- pressed wish that he should be nameless in this connection (as he is in hundreds of other kind deeds), I have no right to contend. The most important single result of the previous experiments with the bolometer had been the establishment of the fact of selective ab- sorption of the solar rays by the earth's atmosphere. The results of this action are so important that I may be permitted to quote from Professor Langley an elementary exposition of them. He says : " Our observations at Allegheny had appeared to show that the atmosphere had acted with selective absorption to an unanticipated degree, keep- ing back an immense proportion of the blue and green, so that what was originally the strongest had, when it got down to us, become the weakest of all, and what was originally weak had become relatively strong, the action of the atmosphere having been just the converse of that of an ordinary sieve, or like that of a sieve which should keep back small particles analogous to the short wave-lengths (the blue and green), and allow freely to pass the large ones (the dark-heat rays). It seemed from these observations that the atmosphere had not merely kept back a part of the solar radiation, but had totally changed its composition in doing so — not by anything it had put in, but by the selective way in which it had taken out, as if by a capricious intelli- gence. The residue that had actually come down to us thus changed in proportion was what we know familiarly as ' white ' light, so that white is not ' the sum of all the radiations,' as used to be taught, but * The amount of heat received from the sun's rays, falling perpendicularly on a square metre of the upper surface of the earth's atmosphere, in a minute of time. SKETCH OF PROFESSOR S. P. LANGLEY. 407 resembles the pure original sunlight less than the electric beam which has come to us through reddish-colored glasses resembles the original brightness. With this visible heat was included the large amount of invisible heat, and, if there was any law observable in this 'capricious' action of the atmosphere, it was found to be this, that, throughout the whole range of the known heat-spectrum the large wave-lengths passed with greater facility than the shorter ones." The effect of this selective absorption on the visible rays is to cut out the shorter wave-lengths proportionally more ; so that to an eye outside of the earth's atmosphere the sun would be far bluer than to us. On the heat-rays taken together, the total amount of the absorption is very great, far greater than had been previously supposed. Professor Langley's experiments give a very great increase in the amount of solar heat reaching the earth over previous determinations, so that for example, according to him, the solar radiation is sufficient to annually melt an ice-shell one hundred and seventy-nine feet thick all round the earth. According to previous determinations, one hundred and ten feet in thickness could be melted. But while Professor Langley finds a vastly greater amount of heat supplied by the sun, his law of the selective absorption comes in to profoundly modify its terrestrial manifestations. Were there no such selective absorption, the temper- ature of the soil in the tropics, under a vertical sun, would probably not rise to that of the freezing-point of mercury. "The temperature of this planet, and with it the existence, not only of the human race but of all organic life on the globe, appears, from the results of the Mount Whitney expedition, to depend far less on the direct solar heat" than on the hitherto neglected quality of selective ab- sorption. The bearing of the observations at Mount Whitney on a great number of important questions, the temperature of the sun, the radia- tion from the sky, etc., etc., can not be here considered for want of space. The solar spectrum previously known was but half of that mapped out by the expedition, and there is good reason to believe that Professor Langley's observations have now revealed the whole of it to us. The partial results of these investigations, published from time to time in foreign periodicals, have done much to make Professor Lang- ley honored in other countries than his own. In 1882 he was invited to address the British Association for the Advancement of Science at Southampton, and did so. His paper on that occasion reminds one of that of February, 1874, in the astonishing fullness of experiment, thought, and judgment which seems to lie just back of the sentences. It comes from a full mind. In the spring of 1885 Professor Langley goes to England at the invitation of the Royal Institution to lecture before it. There are many other most interesting researches of Professor Lang- 408 THE POPULAR SCIENCE MONTHLY ley's which should be referred to here, were it not for limited space. His observations on the moon's heat ; on the solar eclipse of 1878 (at the summit of Pike's Peak) ; his direct comparison of the sun with the molten metal of a Bessemer converter ; his investigations at Mount Etna, Pike's Peak, and Mount Whitney, on the conditions of vision at great altitudes, all deserve more than this brief notice. His published scientific papers are very numerous. A list of the more important of these follows this article. There are forty-six sepa- rate papers in the years from 1869 to 1885. Besides these, the maga- zines have contained many more popular articles ; and his courses of lectures at the Lowell Institute, the Peabody Institute, and elsewhere, have been most successful. Professor Langley is a member of the National Academy of Sci- ences and of numerous American and foreign bodies, and has received the recognition of honorary degrees from various universities.

A PERNICIOUS POLITICAL TENDENCY. THERE is no more important subject for consideration in the present day than that which is involved in the question whether the powers of govern- ment ought to be extended or restricted. The tendency, as every one must be aware, is toward extension, not restric- tion, and one of our contemporaries, the " Christian Union," snubs a corre- spondent who suggests restriction by telling him that he is "about half a century behind the times." The ear- liest form of government, it proceeds to say, is military despotism, the next is one of police regulation ; while the happy dispensation under which we now live is one of industrial co-opera- tion. Government is " organized to do for the community, by community ac- tion, whatever it can do better in that way than in any other." This is a little enigmatical, suggesting as it does that "government" might proceed in a great many other ways than by com- munity action ; but we may perhaps assume the meaning to be that govern- ment is organized to do for the com- munity whatever can be better done through its agency than by any form of private effort or enterprise. The first objection we make to this position is, that a great deal of ambi- guity attaches to the word "better" as here employed. The resources of the Government are practically boundless ; and that the Government, with bound- less means, should do a particular work " better " than it would be done by pri- vate individuals with limited means, is not quite decisive of the question whether the Government should under- take the work or not. Anything can be done well if money without stint is applied to it; but the question remains, Are government methods of doing work really beneficial to the people ? If the Government undertook to manage all the private gardens in the country, on the understanding that it might levy whatever taxes were necessary for the purpose, no doubt there might be a considerable improvement, on the aver- age, in the way in which lawns and flower - beds and vegetable patches would be kept. It would take time to organize the necessary army of garden- ers and laborers ; but the thing could probably be accomplished in the end. There would be fat places for the poli- ticians and clerkships without number, in addition to the actual outside work- ers ; but the vast machine would sooner or later be brought into motion ; and then no doubt some people, carried away by their admiration for the great- er uniformity of government work, would proclaim that the principle of state management had scored another triumph. But meanwhile where would the money come from? Would the whole question of expediency be decid- ed by pointing to the fact, if it were a fact, that, on the average, gardens were kept in better shape by the Govern- ment gardeners than they had been by the private owners? Would not the question of economy call loudly for consideration? And would it not be a further question whether Government was not doing more harm by diminish- ing the power of individual initiative than it was doing good by keeping hedges, and borders, and walks in su- perior trim ? When, therefore, we hear of Govern- ment doing this or that thing " better " than private enterprise would do it, we should like to go below the surface of things and examine a little into under- lying questions, economical and moral. Every one seems to admit that a be- EDITOR'S TABLE. 411 nevolent despotism would do certain things " better " than they are done by oar republican Government. "Why is it, then, that we will not hear of any kind of despotism — that our repugnance to a benevolent despotism is scarcely less than our repugnance to a purely selfish one? Because we hold that the word " better," as applied to the work of a despotism of any kind, is a very shallow " better " ; and that, while cer- tain superficial aspects of the national life might be improved under such a regime, the deep and abiding interests of the country would suffer. "Well, what people have to learn is that something despotic attaches to all government ac- tion outside of the sphere which pe- culiarly belongs to government, the protection of the community from for- eign, and of individuals from private, aggression. All government action is of a compulsory character; all takes away something from the liberty of the individual ; all stands in the way of the spontaneous development of the agen- cies for doing what the Government unnecessarily undertakes. Social bonds are not knit by what the Government does, but social bonds are knit by ev- ery development of private enterprise, by every spontaneous development of means to ends for social purposes. If government managed everything for us, society in the true organic sense would cease to exist. The individual would find himself at every turn face to face with a great mechanism, and would no longer have the sense of be- longing to a living and growing sys- tem. It is easy to sneer at these ideas as being "half a century behind the times"; but whoever does so should remember that at least one illustrious name stands associated with them, and that it is not usual to cite the author of the " Synthetic Philosophy " as a man left in the rear of the world's intellect- ual march. " Democracy," we are told, has left these notions behind, and will never take them up again. What de- mocracy will or will not do in the fu- ture it is rash to assert ; for our own part we venture on no predictions. We should just wish, however, to remark that it settles no question of right or wrong, truth or error, to say that "de- mocracy " has done so and so. De- mocracy, we presume, is not infallible. These abstractions, however, are most misleading. Tell us the exact truth : that a certain community living under certain institutions, and at a certain stage in its intellectual and moral de- velopment has turned its back on a par- ticular set of ideas; and we shall not only know precisely what you mean, but shall also be able to estimate the importance and value of your state- ment. But tell us that the abstraction " democracy " has done the same thing, and we are entitled to reply that no abstraction is capable of any such ac- tion. On the principle our contemporary has laid down, it is impossible to say at what point state action should cease ; for the more the state undertakes the more it is impelled to undertake. To add one new function to-day is to pre- pare for the addition of a dozen within a few years. Take the case of the Eng- lish Government. Having the post- office under its control, it was led to make use of the post-office organization for the issue and payment of money- orders. Then followed the establish- ment of post-office savings-banks ; then the absorption of the telegraph system ; then the establishment of a parcel-de- livery and general express business. On the Continent the post-office collects debts, pays newspaper subscriptions, and carries money in very much the same way as the express companies do here. Where is this kind of thing to stop ? The larger the organization, the greater the temptation to apply it in some new way, or to accomplish by means of it some new object. There are those, no doubt, who think this increasing influ- ence and interference of government a 412 THE POPULAR SCIENCE MONTHLY. hopeful sign, and who look forward to the day when government will seize upon all the great lines of industry and forever hreak the power of private en- terprise ; hut few intelligent persons in this country are of this turn of mind. We would therefore say to those who wish to preserve upon this coutinent a society alive in all its parts and full of individual initiative and resource, to heware how they give heed to the seductive doctrine that government should undertake whatever it can do " better " than private individuals. We might pay too dear for having our gar- den-walks rolled by government rollers, and too dear in many other ways for the alleged benefits of official rule. BEECHER ON EVOLUTION. The Eev. Henry Ward Beecher has worthily crowned his splendid career as a liberal religious reformer by an- nouncing and entering upon a series of discourses to his congregation in expo- sition and defense of the doctrine of evolution in its religious aspects and hearings. The taking of this noble stand in a formal way at the present time is undoubtedly the most moment- ous act of his intellectual and profes- sional life. At a time when most men are worn out and ready to retire, when enthusiasm is usually chilled and opin- ions become hardened and unadaptive, Mr, Beecher strikes into a new field with the fire of youth, and takes the leadership in a movement of religious reform of quite incalculable moment. He commits himself boldly and broadly to the most comprehensive, far-reach- ing, and revolutionary truth yet estab- lished by science, and which carries with it a total reconstruction of the relations of science and religion ; and this he does in opposition to the nar- row-mindedness and dull indifference of the community, and more especially to the organized ignorance, the sacred traditions, the inveterate prejudices, the bigotry and the intolerance of the theological world. We confess to un- affected admiration for the sagacity, the independence, the courage, the loy- alty to conscience and to truth, that have prompted Mr. Beecher to take this brave and significant step. Undoubtedly he has undertaken a very difficult task, and he is aware that he has not much child's play before him. But there are important advan- tages in his position ; and the first of these is, his independence of religious organizations : he has to reckon only with his congregation. In various re- spects, no doubt, his audience is but poorly equipped to appreciate the value of facts and the force of reasoning on the subject of evolution. For it must be remembered that the proof of that great principle is not of a kind to be given to an uninstrueted person at a sitting. It is the diversity, and wide concurrence, and cumulative confirma- tion of the evidences that give the over- whelming force of demonstration to the theory. It must be assumed that Mr. Beecher's congregation has not been very well prepared in the philosophy of evidence, any more than they are familiar with the sciences from which the proofs are derived. It consists of bright, intelligent people, whose men- tal cultivation has been chiefly in lit- erature, politics, and theology; while in proportion to their proficiency in these will they rank low in science knowing little of its facts and less of its spirit and method. Nevertheless, Mr. Beecher's congre- gation has had a very valuable and important preparation, which will be pretty sure to carry them with him in the present movement. Evolution is by no means a thing of yesterday with Mr. Beecher; he has long been on the road to it. The doctrine of progress has been one of the favorite and most powerful elements of his preaching for a quarter of a century. It has been the key to his theological philosophy, EDITOR'S TABLE. 413 and his people have been trained into thorough familiarity with the concep- tion as an all-interpreting principle in both theology and politics. Yet evo- lution is only the expansion and full scientific elucidation and wider sweep of application of the idea of progress. Nor is there anything now in evolu- tion more fatal to orthodoxy than there was a generation ago in the first vague divergence from the old rigid dogmatic systems in recognizing a progressive ele- ment in religion. Mr. Beecher and his people have been themselves evolved into their present position, and might furnish an object-lesson in the law of development. There will probably be more trouble in accepting the newer name appropriate to the later stage of growth than there has been in assimi- lating the underlying truth. We congratulate Mr. Beecher on his intrepid course, and his determination to bring his pulpit into harmony with those revelations of science that a rere- shaping the thought of the age ; and we commend his example to the nu- merous clergymen who give their pri- vate assent to evolution doctrine, and then go on promulgating the old beliefs from desks sacred to antiquated error. SPREADING IT TOO THIN. At a meeting of the Massachusetts Teachers1 Association, held a short time ago, President Eliot, of Harvard, spoke in strong terms of the unsatisfactory character of the great majority of the so-called high-schools of the Common- wealth. Out of a total of two hundred and twenty-eight such schools, seventy- two only had as many as three teach- ers, and the whole together sent only one hundred and ninety-nine students to the colleges of the State during the year 1884. The simple fact, President Eliot states, is that the majority of the schools are not fit to prepare youths for matriculation at college, though in the general system of public-school educa- tion that is a recognized part of their function. " It has been the policy of the Board of Education," wo are told, " to encourage small towns to establish high-schools in order that as large a percentage as possible of the popula- tion may have a school higher than the grammar-school within easy reach." That policy has been so far successful that over ninety per cent of the popu- lation nominally enjoy the privilege in question. The result, however, is a thinning and impoverishing of the edu- cation just in proportion to its exten- sion. Seventy-five of the high-schools are maintained in towns of less than five hundred families. Nearly half of the whole number existing have less than sixty pupils each. President Eliot naturally calls for such a change in the law as may enable two or three or four smaller towns to establish a joint school, and employ in rendering it really effi- cient the funds which now are more or less frittered away upon the mainte- nance of two or more weak and ineffi- cient schools. He also suggests that the colleges should meet the schools half- way by establishing liberal sys- tems of options, so that no student need be debarred from the higher advantages that the colleges afford by his inability to pass an entrance-examination in one or two subjects in which he feels no interest, and which he has no ulterior intention of pursuing. We call attention to this matter be- cause we have reason to believe that the practical evil which the President of Harvard describes is not confined to the State of Massachusetts, but is wide- ly prevalent throughout the country at large. It is a result, no doubt, of our democratic ideas, and of the local jeal- ousies which, it will hardly be ques- tioned, democratic institutions bring in their train, that we try to bring to every man's door what we bring to one man's door. The thing can only be accom- plished, however, at the expense of a marked deterioration in the article sup- 4H THE POPULAR SCIENCE MONTHLY. plied. A good and well-equipped high- school can not, as things now are, be maintained in every village and town- ship. We may have the name of the thing, but the reality we can not have. If the system could be worked at all it could probably be worked as success- fully in Massachusetts as in any State of the Union ; but President Eliot tells us that it does not work well there at all, and that, owing to the poverty of the great majority of the schools, a gap which ought not to exist, and which is inconsistent with the theory of the pub- lic-school system, has established itself between the so-called high-schools and the colleges. The schools ought to pre- pare their students for matriculation at the colleges ; but the most of them neither do nor can do anything of the kind. What applies to the high-schools ap- plies also, generally speaking, to the colleges themselves. They are not what they ought to be, simply because there are too many of them. The conse- quence is, that there is a great deal of false and shallow culture abroad in the land. A college ought to be a place where a youth would be certain to come into contact with men of an altogether superior order of thought and attain- ment. It ought to be the center of a true intellectual life. Of all our col- leges, how many answer this descrip- tion? It is needless to say that the country does not possess a sufficient number of men of real intellectual mark to fill all the chairs in our innumerable " colleges." If it did, we should in- deed be exceptionally favored. Now, the effect of shallow learning tricking itself out in the garb of real erudition is to confuse all intellectual perceptions and standards. We do not say that a little learning is a dangerous thing, but we say that a little learning that mis- takes itself for great learning is apt to make more or less of a fool or a char- latan of its possessor. We do not know whether there is much to be gained by struggling against what seems to bo one of the main currents of the time ; but we are profoundly convinced that the cause of American culture calls for concentration not dispersion of effort, for centralization as opposed to local- ization, for the sinking of petty rival- ries in the endeavor to found strong, permanent, and widely beneficial insti- tutions. Let our common schools which penetrate everywhere be placed on as sound a basis as possible ; let high- schools be established in centers where they can be vigorously and generously sustained ; let our colleges and univer- sities be proportioned in number to the need actually existing for the highest culture, and let them have such sup- port as national and individual interest in such culture prompts — and we shall then have all the necessary means for making the American people the equals in education of any other nation in the world. At present we have a vast but somewhat disjointed apparatus, and the results, however soothing they may be in some respects to democratic pride, are, from the point of view of national culture, far from satisfactory. We call particular attention to the weighty testimony of Dr.Edward Frank- land, the eminent English chemist and sanitarian, to the claims of the Yellow- stone National Park as a great Ameri- can health resort in winter for invalids with chest and pulmonary difficulties. Dr. Frankland has investigated this sub- ject long and carefully, and is especially familiar with the conditions and effects of the celebrated Engadine Swiss sani- tarium in the valley of Davos. Dr. Frankland came to this country last summer, attended the British Associa- tion atMontreal,and, having heard much of the Yellowstone Park, he went there and spent considerable time in examin- ing its claims as a great winter sanita- rium for the American people. He con- tributes to the " Monthly " a valuable LITERARY NOTICES. 415 paper, giving the results of his observa- tions, and the more valuable, as it is a comparative study of the health-merits of the two localities ; the marked advan- tages being in favor of the Yellowstone Park over the celebrated Swiss valley. The article is most instructive, and the subject one of interest and moment to our people. LITERARY NOTICES. INTERNATIONAL SCIENTIFIC SERIES, VOLUME L. The Common Sense of the Exact Sciences. By William Kingdon Clifford. With One Hundred Illustrations. New York : D. Appleton & Co. Pp. 271. Price, $1.50. Professor Clifford was applied to in 1871 to prepare a volume for the " Interna- tional Scientific Series." He was asked if he would undertake a book to be entitled "Mathematics for the Non-Mathematical," the object of which should be to find out how far it is possible to go in explaining mathe- matical ideas to persons of intelligence who have had none of the higher mathematical training. This idea had been before pro- posed to several mathematicians, who agreed that nothing could be made of it ; but it was suggested that if anything could be done with it Clifford's was the genius to do it. Pro- fessor Clifford was struck with the idea as novel and interesting, and said he would make a study of it and see what it promised. The result was so favorable that he decided to undertake the book and give such at- tention to it as his slender health and vari- ous pre-engagements would allow. There was but little doubt that the project was eminently suited to the peculiar character- istics of Clifford's mind ; and that the sub- ject was certain to be handled by him with originality and result in a valuable con- tribution to mathematical literature. But it soon became apparent that there was a serious question about the possibility of his accomplishing the task at all, on account of his declining health. He, however, did considerable work on it, but left it in an unfinished and fragmentary condition at his death in 1S79. In arranging the plan of the work it was Professor Clifford's intention to treat the fundamental conceptions of mathematics in six parts or chapters under the heads of Number, Space, Quantity, Position, Motion, and Mass. Of these six subjects he dealt with but four, dictating the chapters on Number and Space completely, the first por- tion of the chapter on Quantity, and nearly the entire chapter on Motion. Shortly be- fore his death he expressed a wish that the book should only be published after very careful revision ; that the title, The First Principles of the Mathematical Sciences ex- plained to the Non-Mathematical, should be abandoned, and that the volume should be entitled The Common Sense of the Exact Sciences. It was not easy to find a mathematician who would undertake to finish Professor Clifford's work. Upon his death, Professor Rowe, of University College, engaged to do it ; but he also died before accomplishing the task, so that the final revision had to be made by still another hand. There are parts of this work contributed by Professor Clifford which answer finely to the original idea of it, and show what might have been done if he had lived and adhered to the first conception. A mistake was made by the subsequent editors in seeking to finish the work as they thought Clifford would have done it, rather than as in their judgment it might seem best. As it is, the work will probably be found more attractive to mathe- maticians than to non-mathematicians. Annals of the Astronomical Odservatory of Harvard College. Vol. XIV. Parts I and II. Observations with the Merid- ian Photometer during the Years 1879- '82. By Edward C. Pickering, Director, aided by Arthur Searle and Oliver C. Wendell. Cambridge : John Wilson & Son, University Press. 1885. Almost the earliest record we have of astronomical observation is the catalogue of 1 ,028 fixed stars in the " Almagest " of Ptole- my, the epoch of which is a. d. 138. The chief value of this catalogue consists in its clas- sification of the stars into six magnitudes, which classification, so far as those stars which are visible to the naked eye are con- cerned, has been continued to the present day. Since that time many other astrono- mers have made systematic observations on the relative brightness of the stars, the 416 THE POPULAR SCIENCE MONTHLY. comparisons up to the present century hav- ing been made either by the naked eye, or with the assistance of an opera-glass only. About the middle of this century photom- eters specially adapted for comparing the light of the stars were first used by German astronomers. Zollner invented a photom- eter, consisting of a telescope in which the light from a kerosene-lamp, admitted through a very small hole and presenting the ap- pearance of a star, is compared with the real star under observation. C. S. Pierce, of the United States Coast Survey, used such a one in the construction of a photometric cata- logue of 494 stars, published in Vol. IX of the " Annals of Harvard College Observatory." His description of his difficulties with this very imperfectly contrived and still more imperfectly constructed instrument would be amusing, if it did not excite regret that so accurate an observer and excellent a mathematician should have been weighted with an instrument so poorly adapted to the work. Up to within a few years, only about 500 stars had been the subject of photo- metric observation, and for some time it has been regarded as highly desirable that sys- tematic comparisons should be made of the light of all stars visible to the naked eye. In Vol. XIV of the "Annals of the Ob- servatory of Harvard College " we have the records of the most extensive and complete photometric observations ever undertaken. The great attention which Professor Pick- ering, the director of the observatory, has given to astro-photometry, and the large experience he has had with photometers, both of his own and others' construction, peculiarly fitted him for such a task. Part I of the " Annals " opens with a description of the meridian photometer devised by Professor Pickering. Having ascertained by experiment that any change of position on the part of the observer had an injurious effect upon the observations, he constructed his instrument in the form of a broken transit, in which, the line of sight being always horizontal, stars at all altitudes could be observed without moving the head. Experience with other photom- eters had also satisfied him that no arti- ficial light could be a proper standard of comparison for the light of a star. A real star was therefore chosen, and the fact that the pole-star is always visible, and its light, on account of its very slight changes of alti- tude, a constant quantity, directed him in his choice of it as the standard of compari- son for all stars. To make sure that it was otherwise suitable, a large number of ob- servations were made of the pole-star, to ascertain if its light was subject to any periodical variation. A reliable instrument and perfect stand- ard having been thus obtained, and many preliminaries settled which it is impossible to touch upon here, observations were begun in October, lS^, and continued till Septem- ber, 1882. During this period seven hun- dred series of observations were made, in- cluding 94,4*76 separate comparisons, the result being that every star not fainter than the sixth magnitude, between the north pole and thirty degrees of south declination, was compared from three to fourteen times with the pole-star. The whole number of stars thus compared is 4,260. The space to which this review is neces- sarily restricted renders it impossible to give even a passing notice to the immense amount of work expended upon the subject of astro-photometry as recorded in these "Annals." An idea can be formed from the statement that there are in all ninety-one tables, some of which occupy several pages. The " General Catalogue," constituting Table XXVII, alone occupies 211 pages, each line having twenty-six columns, one of which has fourteen sub-headings. Part II of the "Annals," the publication of which has been delayed till the present year, is largely devoted to a discussion of the work of those astronomers, from Ptolemy to the present day, whose estimates of the relative magnitudes of the stars Professor Pickering has chosen for comparison with his own. A very complete list of all known or suspected variable stars is also given, with copious notes as to dates and observers. There is also a chapter on the distribution of the stars. Professor Pickering does not close his work with the advancement of any theories of his own. But, for whatever purpose an exact determination of the relative magni- tudes of the stars may be desired, either for the discovery of variable stars, or to as- LITERARY NOTICES. 417 certain the position of the sun in the Galac- tic Cluster, this volume of the " Annals " fills a place which no other work yet published can make any pretense to. Whether we consider the perfection of the instrument employed, the plan of observatiop pursued, the accuracy and care with which the ob- servations were made, the large number of stars observed, the completeness of the rec- ords, or the exhaustive comparisons that have been made of the observations with those of other astronomers, we are equally satisfied that, so far as the photometric ob- servation of all stars visible to the naked eye in northern latitudes is concerned, the work of Professor Pickering and his able assistants leaves nothing to be desired. The Chemistry of Cookery. By W. Mat- tieu Williams. New York: D. Apple- ton & Co. Pp. 328. Price, $1.50. Since the publication of Johnston's " Chemistry of Common Life," thirty years ago, no book so important has appeared in this line of inquiry as the volume before us. Johnston's work was of broader scope, and, in fact, contributed little to the science of the culinary preparation of foods, to which Williams's work is devoted. Much has been done in this direction in the last generation, and a work was needed embodying the most important practical results. This Professor Williams has now given us in a very satis- factory form. Of the extent and impor- tance of the information conveyed in his pages nothing need be said to the readers of " The Popular Science Monthly," in which the successive articles have appeared ; but, now that they are collected together and offered as a treatise on the science of cook- ery, it is proper to state that the work has been ably done, and is entitled to rank as a standard upon its subject. Mr. Williams has given us " the present state of knowl- edge " on the chemical changes to which alimentary substances are subjected by cus- tomary kitchen operations. His facts and his chemistry are to be relied upon, and his conclusions are generally made with judg- ment, but some of his speculations may be extreme, and will be received with caution. His work has been criticised as if he had made too much of the test-tube and analyti- cal operations, and built unwarrantably upon vol. xxvii. — 27 their results. There are, of course, many things about organic substances and their subtile changes which chemistry can not ex- plain, and it certainly can not give us a complete science of foods. But the author of the present work is quite aware of this, and we do not think he has unduly strained the resources of his science in his efforts to elucidate the subject. His book will prove invaluable to read, for practical instruction, for reference in using common cook-books, and as a text-book for classes wishing to study the science of cooking in a careful and thorough manner. A Text-Book of Hygiene. By George H. Rohe, M. D., Professor of Hygiene, Col- lege of Physicians and Surgeons, Bal- timore. Baltimore: Thomas & Evans. Pp. 324. Every important division of the subject receives some attention in this treatise. It is intended to present the essential facts upon which the art of preventive medicine is based, in such manner as to form a guide for the American student, practitioner, and sanitary officer. Beginning with general considerations in regard to air, water, food, and soil, the author goes on to the special hygiene of dwellings, hospitals, and schools, and takes up also industrial, military, ma- rine, and prison hygiene. Several chapters are devoted to personal hygiene. Histories of the epidemic diseases are given, and the subjects of disinfectants, quarantine, and vital statistics are also included. A list of special works is given with each chapter. The author makes little claim to originality ; the qualities which he has especially sought are comprehensiveness and reliability. The Microtomist's Vade-Meccm. By Ar- thur Bolles Lee. Philadelphia: P. Blakiston, Son & Co. Pp.424. Price, $3. This work — " a hand-book of the meth- ods of microscopic anatomy" — has been prepared chiefly with the design of furnish- ing a complete but concise account of all the methods of preparation that have been recommended as useful for the purposes of microscopic anatomy. In order to make it also a suitable guide for beginners, a gen- eral introduction has been added, and intro- ductory paragraphs have been prefixed, when needful, to the different chapters, 418 THE POPULAR SCIENCE MONTHLY. which, taken all together, go far to make up a formal treatise on the art. To fur- nish to instructed anatomists, for whom the book is primarily designed, information on points of detail as to which their knowl- edge or memory may be at fault, a collec- tion of formulae is given and a number of special methods are described. For begin- ners, again, a collection is furnished of ex- amples, which are not intended for imita- tion, but as hints suggestive of the most fit- ting processes. The Diamond Lens, with other Stories. By Fitz-James O'Brien. New York : Charles Scribner's Sons. Pp. 337. Price, paper, 50 cents. Mr. O'Brien was of Irish birth, a poet and story-writer of bright genius, whose contributions to the newspapers and maga- zines attracted much attention when they were published, and were generally popular and widely read, showing distinct originality and strong powers of penetration and de- scription ; they deserve to be remembered. The present series, including a baker's dozen of the stories, was published in 1881, with a biography of the author, by Mr. William Winter, and now appears again in a second edition. The Life of Society. By Edmund Wood- ward Brown. New York : G. P. Put- nam's Sons. Pp. 270. Price, $2. This work is intended to present a gen- eral view of the various factors, in nature and man, that work upon the structure and methods of society, and of the influence, in turn, of society upon man. The author's object has been, in a systematic study, to obtain as deep and adequate a general con- ception of society as possible, " the society of any township or any country of the world to-day, or the whole world of society in the past. ... I wish," he says, " to find an ex- planation of society that will suit wherever society is in any country, or has been in any country or age. I want to get a general view of the constant part of every society. I want to evidence and illustrate this by social and historic facts, drawn from the wide range of society in the past or the present." In general, he adds, " I hope, then, I have shown the real foundation of social science, though, doubtless, there are deficiencies." The subject is considered un- der the head of the effective causes acting upon society, among which arc the influences of the body, man's intellect, man's will, hab- it and usage, disposition and feeling, etc. ; then are considered various features of so- ciety, the influence of the parts of society upon one another, and of the whole upon the parts ; the growth and progress of so- ciety ; its incompleteness, imperfection, and deterioration ; rhythm and epochs in the life of society ; its laws, restraints, liberties, forms, and institutions ; and, finally, a gen- eral view of the spheres of society. The work bears the marks of laborious thought. The Limits of Stability of Nebulous Plan- ets, and the Consequences resulting from their Mutual Kelations. By Pro- fessor Daniel Kirk wood. Pp. 110. This monograph is an inquiry respecting the extreme limits within which a planet's atmosphere may exist, as measured by the distance from the planet's center, at which gravity and the centrifugal force will be in equilibrium; and further into the original or maximum values of the corresponding distances, which were much greater before the members of the system had contracted to their present dimensions. These found, the author applies the bearing of the an- swers to the discussion of the question, "Were the planets formed from nebulous rings 9» Third Annual Report of the Ohio Agri- cultural Experiment Station, for 1884. By William R. Lazenby, Director. Co- lumbus, 0. : Myers Brothers, State Print- ers. Pp. 240. The theory of the station, it is stated in the introductory part of the report, " is to tell the farmers of Ohio what they most need to know " ; and much of the matter in the vol- ume appears to answer to that description. Field experiments were conducted during the year with grasses, fruit, and garden vegeta- bles. The primary object of the tests is to improve upon the best-known methods of cul- tivation and management. Among practical questions, earnest attention was given to as- certaining the comparative value of the best varieties ; the effects of thick and of thin seeding; the effects of sowing or planting at different dates, different distances, and LITERARY NOTICES. 419 different depths ; the value of different methods of manuring and applying ferti- lizers ; and the comparative merits of dif- ferent systems of culture. In connection with this work chemical analyses were made ; experiments were carried on in self- and cross-fertilization ; investigations were made in regard to the best treatment of certain insect enemies and plant-diseases ; the cli- matic conditions were carefully noted ; and the work begun in practical forest-tree cult- ure was extended. The results of the inves- tigations are intelligently and intelligibly described. We regard the document as a good specimen of what such a report shoidd be. An Introduction to the Study of the Compounds of Carbon; or, Organic Chemistry. By Ira Remsen, Professor of Chemistry in the Johns Hopkins Uni- versitv. Boston: Ginn, Heath & Co. Pp. 364. Price, $1.30. The arrangement of this book is some- what different from that commonly adopted by teachers of organic chemistry. The low- est two members of the paraffin series are first considered, then, in order, their halo- gen, oxygen, sulphur, and nitrogen deriva- tives, and after these any peculiarities of higher paraffins and of their derivatives. Fifty pages are devoted to compounds which are at the same time alcohols and acids or aldehydes, etc. Next some account is given of the series of hydrocarbons homologous with the paraffins, and of their derivatives. The benzene series follows, and the various modifications and combinations of the ring molecule are described. Only the more im- portant compounds in each group, and the more important reactions, receive attention. General directions are given for eighty-two experiments, a fair proportion of which the author advises each student to perform ; for details in regard to analysis, etc., larger works are to be consulted. The author has taken pains to make the student see for himself the reasons for adopting the preva- lent views in regard to the structure of the compounds of carbon, and has aimed to give a general view of the whole field, leav- ing minute descriptions to the chemical dic- tionaries. The book is a welcome addition to the unsatisfactory list of text-books in onranic chemistry. A Reprint of Annual Reports and other Papers, on the Geology of the Vir- ginias. By the late William Barton Rogers. New York : D. Appleton & Co. Pp. 832. With Maps. This republication is made in answer to requests by geologists and others for the reports, which have been several years out of print, or very rare. " Of the value of the scientific discoveries, the generalizations, and the descriptions of the geological forma- tions contained in these reports," says the ed- itor, "there can be no better evidence than the frequency with which they are referred to and quoted by all who are engaged in ex- ploring the geology of the Virginias, and the aid they have given to the development of the industrial resources of these States, which they foreshadowed, and in fact often clearly pointed out, at a time when the ge- ology of the State was unexplored." The reports are arranged substantially in the or- der in which they were made, with the pre- liminary correspondence and the arguments addressed to the Legislature for the continu- ance of the appropriations, so that they have an historical as well as scientific value. The author himself desired to condense and codi- fy the reports, and present them with his special map and sections, as a single whole, but time and opportunity never came for doing so. Thus, the editor's work has been simply to revise the reproduction of the origi- nal reports and maps. But a number of pa- pers additional to the reports, relating to the geology of the Virginias, have 'been em- bodied in the volume. An Introduction to Practical Chemistry, including Analysis. By John E. Bow- man, F. C. S. Edited by Charles L. Bloxam, F. C. S. Eighth edition. Phila- delphia : P. Blakiston, Son & Co. Pp. 248. Price, $2. In this manual is laid out a short course of laboratory work, beginning with general chemistry, and including something of both qualitative and quantitative analysis. The book has been made especially for college students who have not studied chemistry, and have time only to gain some familiarity with chemical operations, without devoting much attention to chemical philosophy. The author has avoided the use of complicated or expensive apparatus, and has aimed to give clear and full explanatory details of 420 THE POPULAR SCIENCE MONTHLY. the several processes. Quantities are given in English measures, followed by metric equivalents. In the part devoted to analy- sis are included blow-pipe tests and deter- minations of specific gravity. Several new examples of quantitative separation have been added in this edition, and volumetric analysis has been given a separate chapter. Ninety cuts illustrate the operations de- scribed. A dozen pages of technical infor- mation in regard to reagents are given, also tables of weights and measures, reactions, and solubilities, lists of salts for blow-pipe examination, etc. The uncut edges of the volume are rather inconsistent with the title, " Practical Chemistry." The Fallacy of the Present Theory of Sound. By Henry A. Mott, Ph. D, New York (printed for the author): John Wiley & Sons. Pp. 103. Price, 50 cents. We are informed on page 7 of this book that "in 1877 Dr. II. Wilford Hall pub- lished a work on the ' Evolution of Sound,' in which he carefully considered, step by step, the present undulatory theory of sound, as elucidated by the distinguished authorities." It is furthermore said that Dr. Hall has shown that the current acoustical theory contains numerous fal- lacies, and, from the language adopted throughout the book, we should infer that it is shown to be childish, absurd, and wholly unworthy of credence. Dr. Mott avows his agreement with Dr. Hall, and he gave a lecture before the New York Acad- emy of Sciences, December 8, 1884, stating Dr. Hall's objections to the present theory of sound, and this lecture constitutes the volume before us. Dr. Mott says that the work of exploding this theory has already been pretty well accomplished, and in his preface he gives the names of divers presi- dents of colleges, and professors thereof, from California to New Hampshire and South America, who have accepted " Dr. Hall's discovery," and abandoned as base- less and worthless the hitherto accepted wave theory of sound. We can not here state Dr. Hall's case as re-expounded by Dr. Mott, but discharge our duty by informing all who are con- cerned about it where they can get instruc- tion upon the subject. Nor have we formed any opinion, from having examined the ar- guments, whether the wave theory of sound has been exploded or not. There is getting to be such a free use of dynamite in these latter days among the supposed fundament- als and essentials of science, and long-es- tablished opinions seem so liable to sudden overthrow, that we are losing our interest in the operations. Perhaps the safest rule to follow in these revolutionary circumstances is to abide by long-tested principles until given up by those longest and most pro- foundly trained in the work of scientific in- vestigation. School Bulletin Year-Book of the State of New York, for 1885. By C. W. Bar- deen. Syracuse, N. Y. : C. W. Bardecn. Pp. 160. The " Year-Book " is intended to serve as a convenient educational directory for the State of New York. It contains sketch- es of the county superintendents and county commissioners, and a list of the principals of village schools and academies arranged by counties. Every alternate leaf is left blank, for the insertion of notes, additions, and corrections. Obiter Dicta. New York : Charles Scrib- ner's Sons. Pp. 232. This is a collection of essays, which may be called critical or discursive, according to the mood of the reader, on " Carlyle," " Mr. Browning's Poetry," " Truth - Hunting," " Actors," " A Rogue's Memoirs," " The Via Media," and " Falstaff." They embody the " gratuitous opinions " of one who seems to be an independent thinker, forcibly and often very pungently expressed. Each es- say has its own quality; that on "Falstaff" is a fund of humor; and they are all pleas- ant reading. The Sun and his Phenomena. By the Rev. T. W. Webb. New York: industrial Publication Company. Pp. 80. Price, 40 cents. Notwithstanding the multiplicity of popular treatises on astronomy, the author has thought there might still be room for a description of the sun, which, confining it- self to a brief but careful enumeration of its phenomena, may be found serviceable in elementary instruction. The most re- cent discoveries are taken notice of. LITERARY NOTICES. 4.21 A Catalogue of Chemical Periodicals. By II. Carrington Bolton, Ph. D., Pro- fessor of Chemistry, Trinity College, Hartford, Conn. Reprint from Annals New York Academy of Sciences. 1885. Pp. 58, 8vo. This bibliography contains the titles of the chief chemical periodicals of all coun- tries, from the rise of this literature to the end of 1884. The titles number 182, and eight languages occur ; the arrangement is strictly alphabetical by the first word ; cross- references are freely introduced, from the editors' names to the journals published by them, and from the chemical societies to their publications. Bibliographical details are quite full ; the different titles borne by a periodical at different periods are ar- ranged in chronological order under the first or earliest title. At the end of the paper is a geographical index, arranged by countries and cities. The material for this bibliography has been drawn for the most part from a larger " Catalogue of Scientific and Technical Pe- riodicals— 1665-1882," by the same author. The larger comprises, we understand, over 5,000 titles, and forms a volume of nearly 800 pages; it will be published by the Smithsonian Institution in a few weeks. The present catalogue will be useful to chemists, and especially to librarians. Bulletin of the Philosophical Society of Washington. Vol. VII. 1884. Wash- ington, D. C. : Judd & Detweiler. Pp. 135. This volume contains the minutes of the society and of its mathematical section for 1884. The society continues to show a vigorous growth. The total number of members enrolled, from the beginning in 1871, is 292. Thirty-five new members were added during the year, and the present number of active members is 173. The annual address of the president, James C. Welling, delivered December 6, 1884, was on " The Atomic Philosophy, Physical and Metaphysical." The " Minutes " include, besides this address in full, abstracts of the papers read at the stated meetings of the society, among which we notice, as of cur- rent general interest, Mr. Russell's on " The Existing Glaciers of the High Sierra of Cali- fornia," Mr. Kerr's on " The Mica-Mines of North Carolina," Mr. Russell's on the " Vol- canic Dust of the Great Basin," Mr. Dall's on the " Volcanic Sand that fell at Unalas- ka in 1883," with Mr. Diller's on the com- position of that dust ; and Mr. Dutton's on " The Volcanoes and Lava-Fields of New Mexico." HOW SHOULD I PRONOUNCE ? Or, THE ART of Correct Pronunciation. By Will- iam Henry P. Phyfe. New York : G. P. Putnam's Sons. Pp. 305. Price, $1.25. The author assumes that the subject of English pronunciation has not, as yet, had its main facts and principles clearly and concisely presented ; and that, among exist- ing books, none consider the question em- braced in the title of the present one in its broadest sense, and endeavor to give it an in- telligent and satisfactory answer. His effort has been to supply this lack ; to furnish the reasons for the directions given, and to in- dicate the means of becoming proficient in the very important art. After an introduc- tory chapter presenting general views and principles, the topics are considered of the physical nature of sound, the nature and use of the vocal organs, articulate sounds, the sounds of the English language, alpha- bets, and the English alphabet. The last topic is followed by complete lists of the various sounds for which each letter in the English alphabet stands, and of the various symbols used for each elementary sound, which are claimed to be the fullest that have ever appeared. Then come rules and sug- gestions for becoming proficient in English pronunciation and the indication of the cor- rect pronunciations, according to both Web- ster and Worcester, of more than one thou- sand words that are frequently mispro- nounced. Proper names are considered in another chapter, and a bibliography of the subject is given in an appendix. The Lenafe Stone : or, the Indian and the Mammoth. By H. C. Mercer. New York: G. P. Putnam's Sons. Pp. 95. Price, $1.25. In 1872 a young farmer in Bucks Coun- ty, Pennsylvania, turned up in plowing a "queer" stone, which he took home and threw into a box with his other "Indian curiosities." It was a piece of a broken " gorget-stone," on which could be discerned 422 THE POPULAR SCIENCE MONTHLY carved lines, describing the outline of a mammoth. In 1881 he sold it in a lump with his other specimens to Mr. James Paxon, for the round sum of $2.50. Short- ly afterward, a smaller fragment was found, which, joined to the former one, completed the gorget, and also the design of a party of Indians hunting a mammoth. The ques- tion necessarily arises, Is the stone with its tracings a genuine aboriginal relic ? It is a very important one in American archae- ology. There appears no reason to doubt the entire honesty of all the persons who arc known to have handled the specimen. Unfortunately, the stone itself is not capa- ble of giving evidence ; for it was not seen, scientifically, till it had been cleaned two or three times, and its possessors had scratched over the lines to make them plainer. Its occurrence where it was dis- covered is unaccountable if it is not genu- ine. It has been submitted to experts in aboriginal relics, and they have expressed different opinions respecting it. Three oth- er carved stones have very recently been found on the same farm, the examination of which and their comparison with this one may throw some light on the subject. Mr. Mercer presents the evidence on both sides with seeming impartiality, but evidently be- lieves in the genuineness of the stone. PUBLICATIONS RECEIVED. Report of the Assistant Director of the U.

The American Association. — The next meeting of the American Association is ap- pointed to be held at Ann Arbor, Michigan, beginning August 20th. The Association at its last or Philadelphia meeting expressed a preference for Bar Harbor, Mount Desert, as the place of its next meeting, if suitable ac- commodations could be secured there, nam- ing Ann Arbor as an alternative place. It has been ascertained that, while hotel-room is not wanting at Mount Desert in July and the latter part of September, all possible accommodations are taken up at the time the Association would meet, in August. At Ann Arbor, the university buildings and the rooms usually occupied by the students will be at the disposal of the Association. The British Association. — The arrange- ments for the coming meeting of the Brit- ish Association at Aberdeen, Septemoer 9th, are nearly completed. The president-elect for the year is Sir Lyon Playfair. The general secretaries are Captain Gal ton and Mr. A. G. Vernon Harcourt, while Profess- or Bonny serves for the last time as acting secretary. The presidents of the various sections arc : A, Mathematical and Physi- cal Science, Professor G. Chrystal ; B, Chem- ical Science, Professor H. E. Armstrong ; C, Geology, Professor J. W. Judd ; D, Biol- ogy, Professor W. C. Mcintosh ; E, Geog- raphy, General J. T. Walker ; F, Economic Science and Statistics, Professor Henry Sidg- wick ; G, Mechanical Science, Mr. Benjamin Baker; II. Anthropology, Mr. Francis Galton. The lecture to working-men will be deliv- ered by Mr. Harold B. Dixon, on " The Na- ture of Explosives." The other lectures will be by Professor Grylls Adams, subject not announced, and Mr. John Murray, di- rector of the Challenger Expedition Com- mission, on " The Great Ocean Basins." How Floras are changing. — Professor C. E. Bessey notices, in the " American Naturalist," on the subject of " Plant Mi- grations," a few instances in which certain plants have disappeared from the flora of a part of Central Iowa, to have their places taken by other species coming in from abroad. Fifteen years ago the Dysodia chrysanthemoides grew by the road-side in great abundance ; now it is scarcely to be found, and is replaced by the introduced " dog-fennel," or " May- weed " of New Eng- land (Anlhemis cotula). Then, the small flea-bane {Erigcron divaricalum) abounded on dry soils ; now it is rapidly disappearing. Mulleins have begun to appear, and the squirrel-tail grass (Hordeunijiibatum), which had no place in the flora, is very abun- dant, and has been for ten years. The low amaranth (Amaranlus bii(oides), which was rarely found, is now abundant, and has mi- grated fully one hundred and fifty miles northeastward. Bur grass, also, a most of- fensive plant, has come in, and appears to be rapidly increasing. Professor Bessey is informed by old settlers that in Nebraska the buffalo-grasses were formerly abundant in the eastern part of the State, but have now retreated for a hundred or a hundred and fifty miles, while they have been fol- lowed by the blue-stems {Andropogon and Chrysopogon), which now grow in great luxuriance all over the plains, where twenty years ago the ground was practically bare. The same is taking place in Dakota. Color of Arctic Animals. — Mr. Wallace's theory that the white color of many Arctic animals is due to protective adaptation or mimicry has been disputed by Mr. Meldola, who speaks of some Arctic animals that are not white, and regards that color as having some relation to the radiation or absorption 424 THE POPULAR SCIENCE MONTHLY. of heat. 'Mr. Wallace, defending his view, says that, " if the white coloration of the Arctic animals stood alone, it might be thought necessary to supplement the pro- tective theory by some physical explanation, but we have to take account of the parallel cases of the sand-colored desert animals, and the green-colored denizens of the ever- verdant tropical forests ; and, though in both these regions there are numerous ex- ceptional cases, we can almost always see the reason of these, either in the absence of the need of protection, or in the greater im- portance of conspicuous covering. In the Arctic regions the exceptions are particu- larly instructive, because in almost every case the reason of them is obvious." The Arctic wolf does not turn white, because he hunts in packs, and concealment is not ne- cessary ; the musk-sheep, yak, moose, cari- bou, and reindeer are able to take care of themselves, and need no protection or con- cealment. The glutton and sable are dark- colored because they live in trees, and must look like them. The raven, living on car- rion, requires no concealment, and continues black. Mr. Wallace is of the opinion that color has very little to do with the absorp- tion or radiation of heat, because those mat- ters are largely determined by the struct- ure and surface-texture of the colored sub- stances. A Mystery of the Growth of Trees ex- plained.— Mr. John T. Campbell relates in the "American Naturalist" his discovery of one of the causes of the phenomenon of particular tracts of land being covered with a simultaneous, nearly exclusive, growth of trees of a particular species. Some have ascribed the phenomenon to a peculiar fit- ness of the soil to particular kinds of vege- tation, which he does not find to exist. His own explanation is very simple, and is to the effect that the matter lies wholly or mainly in the fact of the ground being in a fit condition to receive the seeds of the va- rious species when they fall upon it. Seeds of different kinds fall at various seasons, and when the ground is in various condi- tions as to moisture, etc. Those that find the ground in good condition sprout and grow, if no accident occurs to remove the plants when very young. Mr. Campbell has tested this view in his surveys in the occa- sionally flooded bottom-lands of the Wa- bash River, and illustrates it by following the futures of the seeds of three species of trees. The balls of the sycamore or but- ton-wood begin falling early in the spring months, and, if a flood is receding at the time, they stick to the soft, moist banks wherever they touch them, and particularly along the highest parts of the sand-bars. Were it not for the subsequent floods in the same spring, no other trees could grow, for these would occupy the ground. But they are easily killed during their infancy by overflows, and this is what happens to most of them. The Cottonwood is the next in or- der of shedding seed, and, if another flood is receding while this is taking place, it will have killed all the sycamores which it has covered, and sprout the cottonwoods. These in turn may be killed by the next flood. It is the turn of the maples next to shed their seed, and try for the ground. If either of these species succeeds in making wood with- out a flood, it will hold the ground, and its rivals will not be able to get a place. Last spring the edge3 of the successive planta- tions escaped the next floods after the seeds fell upon them, and Mr. Campbell could see along the river-banks three belts of young trees, and distinguish them by their gen- eral appearance. The upper belt was of sycamore, the second (downward) of Cot- tonwood, and the third of soft maple. In June a bigger flood came than any that caused the seeds to sprout, and killed all the young trees. Water-Melon Sirnp. — In response to the inquiry by Dr. H. Carrington Bolton concerning the manufacture of sugar from water-melons (see June number, page 287), Mr. E. A. Gastman, of Decatur, Illinois, writes as follows: "About 1842 the manufacture of molasses was carried on here in Central Illinois from melons. I do not know how extensive nor how successful it was, but I remember very clearly when a boy on the prairies near Bloomington that our neigh- bors frequently raised large crops of water- melons, from which they made molasses." It will be observed that the extract from Boyle's work communicated by Dr. Bolton mentions a " sirup," not sugar. POP ULAR MIS CELL ANY. 4*5 Madness and Crime. — In an address on "Madness and Crime," delivered some months ago, Mr. Clark Bell called attention to a condition of insanity under which crime is sometimes committed which is not recog- nized by the law and is not often taken no- tice of by the courts. It is the condition that exists when the man is perfectly aware of the nature of the act he commits, and of the fact that it is prohibited by the law and is punishable, but is at the same time in- incapacitated by mental disease from con- trolling his own conduct. The most careful discussion of the question has been made by Sir James Stephen, who has proposed as a solution of it the authorizing of juries to bring in a special form of verdict where the existence of such conditions has been proved. It has also doubtless been the element of the case which has often prompted Ameri- can juries to bring in some of those singu- lar verdicts which have caused remark as con- trary to the law and the facts. In Mr. Bell's opinion, " the time has come when legisla- tors must face this question upon its merits. The able and masterly manner in which Sir James discusses it, the decisions in many of the American States recognizing a different test for responsibility, call for a settled law both in England and America, which would be in accord with the principles of justice and commensurate with the civilization of our age. . . . There is no doubt whatever that the uncertainty of verdicts is largely due to the popular conviction of the injus- tice of the law as it now exists, and as it is frequently construed by the courts. ... It is a legislative and not a judicial question, and must receive public attention commen- surate with its great importance in the ad- ministration of criminal jurisprudence." Sorghnm and Beet Sngar in the United States. — Professor H. W. Wiley, chemist of the Department of Agriculture, in his report on " Northern Sugar Industry," gives the amount of sorghum-sugar manufactured at the principal factories in the United States during the season of 1883 at 726,711 pounds. The factories are at Rio Grande, New Jer- sey; Champaign, Illinois; Sterling, Hutch- inson, and Ottawa, Kansas ; and the Depart- ment of Agriculture. The largest and most successful factory is at Eio Grande, near Cape May, New Jersey, where the soil and climate appear favorable to the production of the crop. A careful calculation leads the author to estimate that the average amount of sugar which can be obtained in market- able form from sorghum is 4-75 per cent by weight of the expressed juice, or 2'37 per cent, or 46*4 pounds per ton, of the cane. Besides this, two other sugars than the crys- tallizable sucrose are present in the juice, but they are not separable in solid form, and enter into the molasses. This yield is pro- portionately very large, and, if the produc- tion of sorghum-sugar should be carried on with success enough to make it a staple crop, the product of molasses will be greater than ordinary consumption can dispose of. The only other uses to which the molasses can be put will be as food for animals and for distillation ; and the latter will be the more money-making. Each gallon of mo- lasses will give a gallon of commercial alco- hol. Happily, this kind of alcohol is said to be only fit for use in the arts. Professor Wiley remarks that the fact must be ad- mitted that the present production of sor- ghum-sugar is not very encouraging after thirty years of endeavor; but nearly all the progress that has been made in it has taken place during the last three years. The out- look is better for the manufacture of beet- sugar, which is pronounced an assured suc- cess on the Pacific coast. The five years' experience at the Standard Sugar Refinery, Alvarado, California, is claimed to have proved that beets raised in that State will yield as many tons per acre and are as rich in saccharine matter as any raised in Eu- rope. During the season of 1883-84 there were produced at this establishment l,027y- 826 pounds of white refined sugar, whilethere were still in tanks at the time of making the report, in process of crystallization, 250,000 pounds more. Corrupt Legislation. — The causes of the defective and corrupt legislation which ap- pears to be one of the crying complaints of the present time have been reviewed in a short pamphlet by Mr. Simon Sterne, who also makes a general suggestion of a rem- edy for them. The causes lie in the meth- ods of procedure of our legislative bodies, which are unsystematic, hasty, and uncon- 426 THE POPULAR SCIENCE MONTHLY sidered. The public good is often the thing least thought of. On the other hand, the predominant general motive is the desire of the party in power to keep the other party out ; and each member of the body has some " axe to grind," either his own, or the axe of his constituents or of some private or corporate interest. The same was the case in England, till the passage in 1848 of the " standing orders," by which a complete sepa- ration was effected in the method of treat- ment of public and of private and local bills. Public bills are now placed under the wing of the Cabinet. Private and local bills are no longer treated as legislation, strictly speaking, but as petitions to Parliament for special immunity or privileges which are conducted by private parties, and are sub- ject to a strict rule of procedure. They are tried as a lawsuit, in which the petition and bill are filed before the beginning of the session, " and opposed at every step, as a whole and in detail, by the Board of Trade and by every private interest which may be menaced or affected thereby. Counter-peti- tions, attorneys, counsel, and a trial, a stand- ing and a day in court to all parties in inter- est before the bill can become a law, pre- vent wrong to individuals ; counsel for the ministry for the public bills, and special counsel for the private bills, committees to aid them in the intelligent discharge of their work, prevent the possibility of working, by collusion, a public wrong." The details of these measures, which we have not space to follow, are carefully adjusted to secure their successful working. The prohibition of spe- cial legislation, which has been incorporated into some of our State Constitutions, is re- garded by Mr. Sterne as unphilosophical ; for there must always be exceptional cases which general legislation can not cover, but for which special provisions are necessary; and it is this need which is recognized in the British system. The prohibition, more- over, defeats itself, for it is evaded, and worse measures are passed for special ends, under the pretense of generality, than could succeed if they were presented in their real character. Mr. Sterne has proposed a de- tailed plan for a system of legislative pro- cedure, modeled after the British " stand- ing orders," which deserves at least to be thought over. British Hens and Eggs.— By actual count (for a census has been taken), Great Britain and Ireland contain thirty million head of poultry of all kinds, twenty million of which may be classed under the head of " chick- ens." The laying hens, which may be esti- mated to constitute one fourth of the chick- ens, or five million head, may lay from sev- enty to two hundred eggs a year. It is safe to average the number at from eighty to one hundred for each hen. This would give four or five hundred million eggs a year. Be- tween a third and a half of the whole stock of poultry are consumed every year. Some of the English cottages derive as much as twenty-two pounds, or a hundred and ten dollars a year, from their fowls, half of which is profit. The poultry are bought up lean by "higglers" or "hagglers," and are fattened for the market by " crammers," who make this their special business. The feeding is performed by machinery, by a rapid process, and the trade is a growing one. The home supply being estimated at eight million chickens a year, and the fowls being valued at two shillings each, we have an annual market value for this stock of £800,000, or $4,000,000. This does not in- clude the turkeys, ducks, and geese, of which eight million are returned in Great Britain and Ireland. If the same proportions of these are brought to market as of chickens, rating them at five shillings a head, we may, by adding the proceeds from them, raise our poultry account to £1,000,000, or $5,000,000. It is impossible to calculate the number of eggs that arc consumed in the United King- dom. If twenty million of the population eat an egg a week, that would be ten hun- dred and forty millions a year. It is known, however, that during 1S83 there were im- ported nine hundred and forty million four hundred and thirty-six thousand one hun- dred and sixty eggs, and they were worth £2,732,055, or five times as many dollars ; and up to the end of August, 1884, six hun- dred and eighty-one million six hundred and eighty-three thousand and forty had been received. The home hens are supposed to furnish five hundred million eggs. Adding these to the foreign supply, and valuing the whole at a penny an egg, we have Great Britain's egg bill, £6,250,000, or $31,250,- 000. POPULAR MISCELLANY. 427 How Yakuts make a Fire— The process of starting a fire employed by the Yakuts and Tungmses of Northern Siberia is quite elaborate, and is thus described by Com- mander Mellville in his " The Lena Delta " : " To start the fire, a dry piece of wood is procured from the high river-banks, many sticks being cut with the axe and rejected until one entirely free from moisture and fit for kindling is found, which is then carefully split and kept dry. The best of the drift-wood is next selected and also split up and chopped into proper lengths. Thus far, so good : but the natives are ignorant of matches, and with only their flint and steel it would seem a difficult matter to start a fire, since they have no rags, either cotton or flax, or any highly inflammable material like sulphur-sticks. But here is where the Yakut and Tunguse ingenuity asserts it- self. The buds of the Arctic willow are forever trying to peep from beneath their thin blanket of snow, and within these buds is a light flossy substance in the nature of thistle-down. Whenever he can, the native gathers a handful of these, and robs them of their down, which he then moistens slight- ly and mixes with ground charcoal, prepared by cooling a lighted piece of birch-wood in the ashes of his hearth. The dampened floss heavily rolled through the charcoal is next covered up and dried before the fire on the same board whereon it was pounded and the charcoal powdered. It is now an excel- lent tinder, igniting quickly into a hot and durable point of fire. But, in addition to it, some light match-stuff is necessary, and, to supply this need, a bundle of fine soft sticks, about thirty inches long, is always kept dry- ing over the fireplace. Before the native sets out on a journey, or, indeed, as often as material is required, the old women of the house take down several of these sticks and carefully shape them into sword-blades. They then rest their knives in beveled notches cut in the flat sides of small pieces of wood, about three eighths of an inch broad, one eighth of an inch thick, and one inch and a half long, and the operation proper begins. Along the wooden sword, which is held against the shoulder like a violin, the knife in its gauge is drawn continuously and rap- idly, and at each draught a thin coiling shaving drops to the floor or into the lap of the operator. A bag full of these fine curls — which, when matted together, very much resemble the American manufactured mate- rial known to upholsterers as ' excelsior ' — is always ready for the traveling native, pre- served dry in the huts beneath the sleeping- skins, and carried in a fish-skin bag on the journey. So, now, with the materials at hand, we will start a fire. The native takes from his skin pouch a bunch of the ' excel- sior ' about the size of a robin's nest, rolls it into a ball, punches a hole in it, and then lays it carefully in the snow. Next, taking a pinch of tinder from the bag which al- ways hangs at his hip, he places it on his flint, and with a quick sharp stroke ignites and incloses it in the center of his nest of shavings, which he then lifts up, holding it lightly with his fingers spread apart for the passage of air, and whirls rapidly around his head at arm's length. At first, a faint, pleasing odor of burning birch steals upon the air, then a light streak of smoke follows the revolving arm, and then the heat within his hand notifies the native that a proper de- gree of ignition has been attained ; he sud- denly ceases his gyrations, tears open the smoking nest, and with a quick puff blows it into flame. Then depositing the blazing ball on the snow, he soon piles his fagots over and around it, and in few seconds his fire is in full blast." Religion and Inebriety. — Dr. T. D. Crothers, considering the question whether faith and prayer, or honest intention on the part of the patient, can alone save him from inebriety, expresses his opinion as in the negative, and says : " In a study of ten cases on this point, I found that seven had been, before and after the beginning of inebriety, active church - members, had experienced conversion and led active lives of faith and prayer for longer or shorter intervals, de- pending on circumstances. Two of these were periodical inebriates, and had, during the free intervals between the attacks, led a most consistent Christian life of faith and prayer. One of the seven exhibited the strange delusion of religious mania when drinking; at all other times he was a quiet skeptic and doubter, but, when once under the influence of alcohol, he was the most ardent religious devotee, exhorting with 428 THE POPULAR SCIENCE MONTHLY great enthusiasm, and asking the prayers of every person he met, to save him. His mind seemed troubled with intense fear of failing to get to heaven, and every thought and exertion seemed directed to this end ; but secretly he drank constantly, never to be stupid, but just enough to keep up a de- gree of excitement. This would last two or three weeks, then merge into a low form of nervous fever, from which he would recover and remain sober for an indefinite time. . . . The other three had been good church-mem- bers before inebriety came on, but on be- coming inebriates left the church." An- other case was that of a clergyman whose inebriate fits always began when he was ad- ministering the wine at the communion. After quoting a few other cases, pertinent but of not quite so striking a character, Dr. Crothers states his conclusions, which are according to the view he has steadfastly held, that " inebriety is a physical disease which must be reached by both physical and psychical means. All methods of treatment must be along the line of natural laws, and include all means, both physical and spirit- ual, that can build up and strengthen the entire man. Spiritual means are only valu- able as they are used with other means, and where they are effectual alone they are the exception to the rule, and can not indicate any direct line of treatment." Butehcr's-Meat and Headaches. — The prescription of a diet largely vegetarian has long been known to be good for per- sons subject to attacks of headache. Dr. Alexander Haig relates, in " The Practi- tioner," a case that came under his treat- ment which indicates to him that this dis- ease and its attendant phenomena are large- ly the result of a poison circulating in the blood, which poison is a product of the digestion of certain foods, especially butch- erVmeat ; and that a cure is best effected by cutting off entirely the noxious food, and aiding the elimination of the poison by the kidneys. The patient was a chronic sufferer from headache, and the afflictions that usually accompany it. lie was a hard student, and was most troubled in winter. On the adoption of a strict vegetarian diet, the attacks, which had been severe, ceased at once, and for six months of the cold half of the year there were only one or two slight ones, although they had been recur- ring weekly. A less strict diet was sub- sequently allowed, and gave practical im- munity, provided butcher's-meat was avoid- ed. It was also found that two or three tumblers of hot water taken every night at bed-time gave increased immunity, and en- abled the patient to take even a little butch- er's-meat occasionally without fear of an attack. The disease was evidently caused by impure blood, and that by imperfection of the digestive process. The connection with butcher's-meat was indicated directly by the facts in the case. It may be ac- counted for possibly by reference to Dr. Michael Foster's suggestion that the pan- creatic digestion of the proteids in excess . is accompanied by the development of bac- teria giving rise to fermentative changes; or by the suggestion made in " Le Progres Medical," that alkaloids are formed in the intestines during digestion similar to those that have been found in the cadaver, and, if they are absorbed in excess, or are not excreted by the kidneys, cause disorders. Another Side to the Clothes Question. — " An Anthropologist " protests, in the " Pall Mall Gazette," that, if an attempt is made to impose European clothing on the natives of New Guinea, they will all be killed off. It is clothes, he asserts, and not liquor or im- morality, that has been fatal to so many na- tives of tropical countries. The Australi- ans and Tasmanians have been clothed, and exterminated, while the North American Indians have been left in their traditional costumes, and thrive. This matter of the natural garb of savages is one " in which Nature can not be safely tampered with. Whether tribes are found clothed only with a loin-cloth, or only with paint, it is the re- sult of a long evolution, an adaptation to environment, and no foreigners should go among such peoples who can not adapt themselves mentally and morally to customs representing that environment. ... In the day that these natives of New Guinea begin to clothe themselves beyond what has suf- ficed for their health, ' they will surely die.' The exact reason for this has not been sat- isfactorily shown, though I have been told in several places that clothing checks some POPULAR MISCELLANY. 429 delicate secretions of the dark skin in warm countries. . . . The germs of European vices are carried too often with European clothes. It is a fact significant of more than female conservatism, to which Mr. Herbert Spencer attributes it, that generally the women of a nude tribe are the last to adopt the fashion of putting on clothes. They are always re- luctant, and sometimes show such shame in their first dress as a European would feel without clothing. In many parts of India there is a profound suspicion of the irrelig- iousness of clothing. The fakir is distressed even by the regulation rag upon which the Government modestly insists, and a fully dressed fakir would be scouted. The late Brahmo minister, Keshub Chunder Sen, ex- pressed the belief that India would never accept a Christ in hat and boots. The mis- sionary should remember that clothes-mo- rality is climatic, and that, if a certain de- gree of covering of the body has gradually become, in the Northwest, associated with morality and piety, the traditions of tropical countries may have equally connected elabo- rate dress rather with the sensualities of Solomon in his glory than with the purity of the lily as clothed by Nature." Persian Carpets. — According to a report by Consul-General Benjamin, of Teheran, the Persian carpets, the manufacture of which constitutes one of the most important features of the industries and commerce of the country, are woven chiefly by the women and children of the peasantry in the villages. A countryman will have a rug made in his own house, and will then take it to the nearest town and sell it for what it will bring. The rooms of the peasantry are small, and hence the rugs are commonly small. Of late years, a larger carpet has been manufactured for the foreign market. Four kinds of carpets are made, large ones and small ones or rugs, the ghilcems, and the umad», or felt carpets. Most of the car- pets intended for the covering of floors, of whatever size, are produced in the central province of Irak and in the districts of Sar- ravend, Garrouste, and Malahir, and are known by the generic name of pharaghan. They are more solid and massive than other Persian carpets, and arc adapted for rooms of large size. Large Persian carpets, which deviate from the usual shape, are made to order, and for an increased price. There are numerous varieties of Persian rugs. In some classes, such as Turkoman, there is general similarity of design, although no two rutrs are altogether identical. In other classes, such as the rugs of Kerwan, Dyo- chegan, or Kurdistan, there is endless va- riety in design or texture. The colors for- merly used in the rugs of Persia were imper- ishable, and rugs a hundred years old show no deterioration in tint. The introduction of aniline dyes at one time threatened the ruin of the manufacture of textile fabrics, but the use of those dyes has been forbid- den by law. The ghikcm, which is largely made in the province of Kurdistan, has a pattern identical on both sides, with firm and brilliant colors, and designs often of extraordinary beauty. Their lightness and flexibility qualify them for portieres and table and sofa covers, and render them easy for transportation. The namids, or felt carpets, are made by forming a frame of the thickness required, or by excavating a space in the ground-floor of a size and depth corresponding with those of the intended fabric. The hair is laid in this and beaten out with mallets, and a design of colored threads is then beaten into the upper sur- face. Silk rugs are peculiar to Persia, and are rare and expensive, although rugs of the finer types, with silken fringes and some- times with a woof of silk in the body of the rug, are not uncommon. Brazilian Oranges. — Oranges flourish and are profitable in all parts of Brazil, and the exportation of them amounts to several millions annually. The Umbigo, the favor- ite variety at Bahia, is without seeds, large, sweet, and delicious, begins to ripen about May, and lasts till September. The most common aDd popular kind at Rio Janeiro is the Siletta, which has a sweet and delicate flavor. The Tangerina is a smaller variety than the Siletta, many-seeded and ripening at about the same time, and has a deep or- ange-colored skin that breaks easily in peel- ing, with an aromatic odor. The orange- orchards are generally situated on low and sandy land, convenient to transportation by water. The trees are planted along from February to May, about fifteen feet apart, 43° THE POPULAR SCIENCE MONTHLY. and begin to bear in about five or six years, yielding then from twenty to thirty oranges each, and increasing their crop for ten years till in full bearing, when they produce from two to three hundred, and, in most favorable circumstances, one thousand oranges a year. The trees remain fruitful for more than thirty years. The cost of cultivating and attending a thousand orange-trees in Brazil is esti- mated at about seventy dollars a year. Climate and Vegetation. — In a paper on the relations of climate and vegetation, M. M. Bergsman, of Flushing, reaches the con- clusion that a mixed climate, with relatively mild winters and warm, sunny summers, is the best suited for the vegetation of the temperate zone. Corn can be cultivated only as a green vegetable in England ; is profitable in Western Europe only to 46°, and in the valley of the Rhine to 49°, but in certain regions of North America to 51°, and even under the Polar Circle in Norway, where it has the sun day and night. Plants much resembling those of Central Europe grow in the Amour region of Siberia, where precipitation occurs only in summer, and that season is warm, in the face of a winter temperature much lower than is observed in the most northern parts of Lapland. Rad- ishes, turnips, rape, and the potato grow as far north as there are settlements, but in the extreme north the potatoes are only as large as walnuts, and the plant never blos- soms in Greenland. When comparing ex- treme continental climates with extreme sea climates, the continental climate has the ad- vantage. The extreme southern limit of phanerogamous plants is in the South Shet- land Islands, latitude 60° to 63° south, and the last trace of vegetation, in cryptogams, is found on Cockburn Island, 64° south. At the same latitude in Northern Siberia is a forest of very high coniferous trees. The chief reason that corn can not be cultivated in Siberia beyond 62°, at Yakutsk, is on ac- count of the constantly frozen condition of the ground at a short distance beneath the surface. In Europe, even, the climate of the northern parts of the British Isles is not suited for many vegetables and other culti- vated plants. It is in Germany where almost all the plants of the temperate zone and those commonly cultivated can be found. Even in that country the summer tempera- ture in general is only a few degrees above that calculated for the latitude. Germany is crossed in July by the isotherm of 68°, and Britain by that of 59°, but the differ- ence in vegetation is not caused by the dif- ference of 9° in mean temperature, but by the difference in the amount of sunshine. Denudation of the Continents. — Mr. T. Mellaid Reade, addressing the Liverpool Geological Society on " The Denudation of the Two Americas," showed that one hundred and fifty million tons of matter in solution are annually poured into the Gulf of Mexico by the Mississippi River. This, it was esti- mated, would reduce the time for the denu- dation of one foot of land over the whole ba- sin— which time has hitherto been calculated solely from the matter in suspension — from six thousand years to four thousand years- Similar calculations were applied to the La Plata, the Amazon, and the St. Lawrence ; and Mr. Reade arrived at the result that an average of one hundred tons per square mile per annum is removed from the whole American Continent. This agrees with re- sults he had previously arrived at for Eu- rope, from which it was inferred that the whole of the land draining into the Atlan- tic Ocean from America, Africa, Europe, and Asia contributes matter in solution which, if reduced to rock at two tons to the cubic yard, would equal one cubic mile every six years. Photographing Colors. — Professor H. W. Vogel has made a report of the final re- sults of his researches on the means of pho- tographing colored objects in their natural shades. Sensitive plates are affected only by the more refrangible rays, so that they present totally unnatural and distorted pict- ures, as to the shading, of colored objects. Believing that the sensitive collodion is af- fected only by such colors as are absorbed by it, Professor Vogel's efforts have been directed to making his plates sensitive to less refrangible rays by alloying the silver coating with a substance capable of absorb- ing those rays. His experiment succeeded with the natural colors, but he could not ob- tain an effect with the duller artificial colors. He then sought for organic substances pos- POPULAR MISCELLANY 43i sessing a power of absorption more intense and lying nearer to the yellow of the spec- trum, and obtained in eosine and in various derivatives coloring substances which hard ly possess more than a broad absorption band in the yellow, and with which he ob- tained the desired result. When these bod- ies were mixed in due proportions with the dry gelatine plates, the yellow of the colored objects appeared quite clear on the photo- graph, but the blue was still always bright- er. Professor Vogel then inserted a yellow glass between the object and the camera, which partly absorbed the blue rays, leaving the yellow unimpaired, and obtained photo- graphs in which the blue, as well as the green and yellow, and partly even the red, parts of the colored objects presented to the observer's eye the same vivid effects as the original. The Objects of Bathing.— The object of bathing, says a writer in the " Saturday Review," is fourfold : to produce a certain amount of nervous shock, that should be followed by reaction and an increased circu- lation of the blood on the surface, resulting in a more rapid change of tissues ; to lower the temperature of the body ; to cleanse the skin ; and to produce pleasurable feelings, and, in connection with swimming, the bene- ficial effects of one of the best forms of physical exercise. The nervous shock and the reaction from it, following the first con- tact with the water, are important points, and to obtain them the plunge or the douche is preferable to any other form of bath. To wade up to the middle and stand shivering and fearful of the momentary feeling of discomfort is neither healthy nor pleasant, and timid persons who dare not plunge boldly into the water should be content with the douche-bath. A large garden hose, with a high pressure of water, held at a distance of fifteen or twenty feet from the body, will give an idea of this most delightful curative and bracing agent. Sea-bathing differs from out-door fresh-water bathing in the greater specific gravity of sea-water and its consequent greater buoyancy and more uniform tem- perature, while the pure air, sunshine, and better sanitary surroundings of sea-side places contribute largely to the results. Mineral baths, as such, have no particular superiority over other baths of the same density and temperature. In addition to the greater healthiness and enjoyableness of out-door bathing, it is probable that the simple exposure of the body to the sun and fresh air is of real benefit, and contributes to the sum total of the good results. Cramps are considered one of the great dangers of bathing, but when they are fatal it is proba- bly the result of syncope or fainting, from failure of the heart's action. A good swim- mer in vigorous health would hardly be wholly disabled by a cramp of only a part of his limbs. Structure of the Edible Birds' Nests. — Mr. Pryer, whose account of his visit to the Gomantin Caves, in North Borneo, has fur- nished a fund of information respecting the edible birds' nests of the Chinese, has pub- lished in a Japan paper an article correcting some misapprehensions that he has found to exist on the subject. That the nests are made from the saliva of the bird he regards as a physical impossibility, for a bird could not secrete in a few days a mass of saliva more than equal, when dried, to the entire bulk of its own body, and then do this nine consecutive times a year. He thinks that some saliva is used by the birds, the alga? being worked up in the bird's mouth in the same manner that mud is worked up by the Japanese swallow. Mr. Pryer at first thought that the black nests owed their color to their being made of the brown out- sides of the algae, while the white nests are made of the inside. This is not correct, for the birds can use only the inside ; the black nests are simply white nests grown old and frequently repaired. How to sleep well. — In sleeping, much depends on securing a comfortable position. Lying on the back would seem to give the most ease, but general experience and prac- tice prove that it does not, and it is liable to some definite objections. In a weakly state of the heart and blood-vessels, and in certain morbid conditions of the brain, the blood seems to gravitate to the back of the head, and to produce troublesome dreams. Persons who have contracted chests, and who have had pleurisy and retain adhesions 432 THE POPULAR SCIENCE MONTHLY. of the lungs, do not sleep well on the back. Nearly all who are inclined to snore do so in that position. For these and other rea- sons, it is therefore better to lie on the side, and in lung-disease to lie on the weak side, so as to leave the healthy lung free to expand. It is well to choose the right side, because, when the body is thus placed, the food gravitates more easily out of the stom- ach into the intestines. Sleeping with the arm thrown over the head is to be depre- cated ; but this position is often assumed during sleep, because circulation is then free in the extremities and the head and neck, and the muscles in the chest are drawn up and fixed by the shoulders, and thus expansion of the thorax is easy. The chief objections to this position are that it creates a tendency to cramp and cold in the arms, and sometimes seems to cause headaches and dreams. The best sleep is obtained when the shutters are closed so as to make the room dark, and the windows are adjusted so as to admit plenty of fresh air. Early rising is not a virtue, unless the riser has secured sleep enough ; and the best rising is obtained when the sleeper wakes naturally. NOTES. Thb works of Darwin, Spencer, Agassiz, Huxley, Adam Smith, and Lewes, are said to be forbidden to be issued from the circu- lating libraries of Russia. The writings of Moleschott, Biichner, Vogt, and Reclus, are also prohibited. Doin, of Paris, has begun the publication of a weekly " Journal des Societes Scienti- fiques," which will contain brief reports of the principal scientific societies, in whatever field, of the great cities of Europe. It costs fifteen francs, or three dollars, postage paid, a year. M. All card has frequently noticed, in passing from his observatory on the Puy de Dome, to the city of Clermont-Ferrand, that, while the air was clear and transparent to the west of the chain of the Puys, it was obscured on the east. On investigation, he found that the obscurity was caused by the dust which the wind, generally blowing from the west, swept up from the rocks over which it passed. This explanation was confirmed by the fact that the fog- like appearance disappeared after a rain. Tiie use of artificial teeth turns out to be of ancient origin. Two curious speci- mens of artificial teeth from the Etruscan tombs, dating from four or five centuries before the Christian era, may be seen in the Museum of Corneto, on the coast of Italy. In the bodies of two young girls, on the jaw of one are still to be seen two inci- sors fixed to their neighbors by small gold rings, while in the other the rings remain, but the artificial teeth have fallen out. The teeth, carefully cut, had evidently been taken from the mouth of some large animal. IIerr Rudolph Jall, of Saarbrucken, Prussia, who has made a special study of volcanic eruptions, states that colliery ex- plosions coincide with or follow closely upon earthquakes. He specifies a number of days during the present season as days which will be dangerous all over Europe. Mr. JosEr-H Thomson, in the relation of his journey through the Masai country in Africa to the Victoria Nyanza, speaks of his troop in one of its marches having "done" little short of seventy miles within twenty-four hours, without a drop of water or a bit of food ! A committee has been formed for organ- izing the celebration of the centenary of the birth of Arago, which will occur on the 17th of March next. OBITUARY NOTES. Among the deaths of the last few months in the scientific world is that of John Bir- mingham, astronomer, of Millbrook, Ire- land, at the age of seventy-eight years. In A. S. Uwarrow, who died a few months ago, Russia has lost one of its foremost archaeologists and the founder of the Archaeological Society of Moscow. He published works on the archaeology of Southern Russia, the tumuli on the Oka (Vladimir), and the Finnish people of the Mesia, who inhabited the country before its colonization by the Russians. Major F. J. Sidney Parry, one of the oldest members of the Entomological So- ciety of London, died on the 1st day of Feb- ruary. Titian Ramsay Peale, the last surviv- ing son of Charles Wilson Peale, the por- trait painter of Revolutionary times, died in Philadelphia, March 13th, in the eight v- sixth year of his age. He was a naturalist, and had fine collections of moths and but- terflies; was one of the founders of the Philosophical Society of Washington ; was a member of the United States Exploring Expedition of Commodore Wilkes ; and was the only survivor of Colonel Long's Expedi- tion to the Rocky Mountains. MICHEL EUO.ENE CHEVREUL. THE POPULAR SCIENCE MONTHLY. AUGUST, 1885. CONCERNING THE SUPPKESSED BOOK. By E. L. YOUMANS. IT will be no news to the readers of this monthly that the volume entitled " The Nature and Reality of Religion ; a Controversy between Herbert Spencer and Frederic Harrison," published by D. Appleton & Co. last March, has been suppressed by order of Mr. Spencer. This catastrophe was the result of a public correspondence carried on between these gentlemen in the columns of the London "Times." Fragments of the letters were cabled to this country as they appeared, and were widely disseminated by the newspapers, pro- ducing some suspense, and giving a confused impression of the affair. At length came the announcement that the disagreeable difference was happily composed ; but with it came also a dispatch ordering the destruction of the book — copies, plates, and all — the damage to be charged to Mr. Spencer. This seemed a curious way of bringing an unpleasant difference between two authors to a harmonious termina- tion ; but, without waiting for explanations, the mandate was obeyed and the book suppressed. The letters themselves are now before us, and as they have not all been previously published in this country, they are herewith submitted to the reader in full : THE SPENCER-HARRISON CORRESPONDENCE. [London Times, May 29, 1885.] A NEW FORM OF LITERARY PIRACY. Mr. Frederic Harrrison has forwarded to us for publication the inclosed let- ter which he has addressed to Mr. Herbert Spencer: " May 28, 1885. " Deae Mr. Spencer : I can not admit that there is anything to justify you in being a party to the American reprint of articles of mine, without my knowl- vol. xxvii. — 28 434 THE POPULAR SCIENCE MONTHLY. edge or consent. I learn accidentally that a volume has appeared in New York, which consists of three recent articles of yours in the Nineteenth Century, printed alternately with three recent articles of mine, with an introduction, notes, and appendix. This re-issue of my articles was made without the knowl- edge of myself, or of the proprietor of the Nineteenth Century, and he tells me that it is a case of piracy. " You now avow (in your letter to me of yesterday) that the volume was issued by your American publishers, and was edited by your friend Professor Youmans, after consultation with you, with your consent and assistance. You also avow that you furnished the editor with controversial comments on my arti- cles, and requested him to append them in his own way — that is to say, you have abetted a clandestine reprint of three articles of mine, interpolated with notes supplied by yourself. I regard this, not only as an act of literary piracy, but as a new and most unworthy form of literary piracy. May I ask if it is proposed to hand you the profits of a book of which I am (in part) the author, or are these to be retained by your American publishers and friend ? " To justify this act you now write that you expected republication in America by my friends. This expectation rests, I can assure you, on a pure invention. No friend of mine, nor any person whatever in America or in Eng- land, has ever suggested to me the republication of my articles, nor have I ever heard or thought of such a project. You quote to me, as your authority, a letter from Professor Youmans, who simply says there is danger of its being done by others, and he adds that I am coming to lecture in America. Again, this is a pure invention. I have never thought of lecturing in America, or of going there, nor has any one on either side of the Atlantic suggested to me to do so. Those who ' convey ' my writings will as readily invent my intentions. Inquiry would have shown that neither I nor my friends had any intention of reprinting any articles — much less yours. And I fail to see how an unverified report that they might be reprinted, coupled with an unverified report that I was going to lecture in America, coidd justify you in promoting and assisting in the unauthorized issue and sale of writings of mine. " This is not a simple case of clandestine reprint. Those of us who do not take elaborate precautions are exposed to have what they write appearing in unauthorized American editions. But it does surprise me that an English writer should connive at this treatment of another English writer, with whom he had been carrying on an honorable discussion. It is, I think, something new, even in American piracy, to re-issue an author's writings behind his back, and sell them interlarded with hostile comment. Reprints, even while they plunder us, spare us the sight of our sentences broken on the same page with such amenities as ' he complacently assumes,' ' loose and misleading statements,' etc. You avow, in your letter of yesterday, that you supplied these comments to my arti- cles ; and if internal evidence did not show them to be yours, by your offer to me to republish them now in England, you treat them as yours. I know no instance of such a practice. It is as if I were piratically to reprint your ' Data of Ethics,' freely interspersed with a running commentary on your practice of ethics, and were to justify my act on the ground that I had had a controversy with you, and that I had heard your friends were about to reprint it. " There is one minor point which serves to show the kind of publication in which you have chosen to take part. My articles in this volume are followed by a cutting from a newspaper account of what the editor calls ' The Little Bethel of the Comtists.' As the volume bears as its subtitle the words, ' A Con- CONCERNING THE SUPPRESSED BOOK. 435 troversy between Frederic Harrison and Herbert Spencer,' tbat newspaper para- graph would only be relevant if it referred to practices in which I had some part, or which I approved. It is well known that I have nothing to do with anything of the kind, and never countenanced it. Nothing of the sort has ever been heard in Newton-hall, where for years past I have presented Positivism as I understand it. The matter is a small bit of polemical mischief ; those who are engaged in plunder are not likely to be fair. But I think it is quite unworthy of a place in a volume for which you are responsible, and which you have authorized and adopt. " You now propose to me to republish this volume in England, where you admit it could not appear without the consent of all concerned. After what you have done I must decline to act with you. I leave your conduct to the judgment of men of sense and of honor. " I am faithfully yours, " Mr. Herbert Spencer. Fkedeeio Harrison." [7'imes, June 1st.] MR. FREDERIC HARRISON'S CHARGE. To the Editor of the Times. Sir: Will you oblige me by publishing the following letter, which is a copy of one to Mr. Harrison, referred to by him in his letter contained in The Times of Friday : " 38 Queen's Gardens, Bayswater, W., May 27, 1885. " Dear Sir : Here are my replies to the questions put in your note of yes- terday. " Just before the middle of January I received from my American friend, Professor Youmans, a letter dated January 2, containing, among others, the fol- lowing paragraphs : " 'And now we have something of a new embarrassment upon which I must consult you. There is a pretty sharp demand for the publication of your con- troversy with Harrison in a separate form, and the publishers favor it. The question is not simply whether it is desirable, for we can not control it. There is danger that it will be done by others, and if that should occur it would be construed as a triumph of the Harrison party — the Spencerians having declined to go into it. '"If I thought no one else would print the correspondence (i. e., the Nineteenth Century articles), I should be in favor of our not doing it. In the first place, for general effect, rhetoric against reason counts as about ten to one. The Comtists are reviving — Harrison is coming over to lecture in this country, and much will be made of his brilliant conduct of the controversy. In the next place he has this advantage of you. Your main work bearing upon the issue is to be sought elsewhere, while Harrison had accumulated all the materials of his assault and gives his whole case, so that the popular effect could not fail to be much in his favor. To the narrower circle of readers who can really appre- ciate the discussion, the republication would undoubtedly be an excellent thing, and I suppose after all it is only these that we should much care for. On the whole it may be politic to reprint. "What do you think about it ? ' " There was thus raised a quite unexpected problem. I had supposed that the matter had ended with your letter to the Pall Mall Gazette; and having expressed (in the Nineteenth Century) my intention not to continue the contro- versy, I hoped it would drop. Here, however, came the prospect of a revival in 436 THE POPULAR SCIENCE MONTHLY. another shape ; and I had to choose between republication by my American friends or republication by your friends, with the implication that I was averse to it. Though I should have preferred passivity, yet, under the circumstances stated, I thought it best to assent to republication. One objection, however, became manifest. While in my replies to you I had pointed out sundry of your many misrepresentations, I passed over others — one reason being that I could not trespass too much on the space of the Nineteenth Century and the attention of its readers. Now, however, when it was proposed that the statements con- tained in your articles should be re-diffused, and take a permanent form instead of a temporary form, I felt that I could not leave unnoticed these other misrep- resentations. Appearing in a volume issued by my American publishers, and edited by my American friend, the implication would have been that statements made by you to which no objection was raised -were correct statements. If words in quotation marks tacitly ascribed by you to me had not been disowned by me (p. 112), it would, of course, have been assumed that I had used them, and that I stood convicted of the absurdity which you allege on the assumption that I had used them. If it had not been shown that an opinion you debit me with (p. 129) is wholly at variance with opinions which I have expressed in three different places, it would naturally have been concluded that I held the opinion. Hence it was clear that unless I was to authorize the stereotyping of these and other errors I must take measures to dissipate them. I therefore pointed out to Professor Youmans the statements which required notice, indi- cated the needful rectifications, and requested him to append these rectifications in his own way. At the same time I forwarded him a copy of the letter which you published in the Pall Mall Gazette, saying that ' if this reprint of the arti- cles is published without this letter, he (you) will inevitably say that his final reply has been omitted. It is needful, therefore, that it should be included.' And along with your letter I sent indications of the points in it which should be noticed. " Do you think I was not justified in this course ? Do you think I ought to have withheld my consent to the republication by my friends, leaving your friends to republish ? Do you think that, having assented to republication, I ought to have let pass without correction your misstatements previously uncor- rected ? If you think either of these things, I imagine that few will agree with you. There is, however, an easy way of bringing the question to issue. All the articles are copyright in England, and can not be republished here without the consent of all concerned. I do not suppose that Mr. Knowles will raise any difficulty; and if you agree to the re-issue of them here, I am quite willing that they should be re-issued. If you think that anything said in refutation of your statements should not have been said, we can easily include an appendix in which you can point out this; and then, if you wish it, copies of the volume can be sent round to the press. "Of course I preserve a copy of this letter with a view to possible future use. " Faithfully yours, " Herbert Spencer. " Frederic Harrison, Esq." I will add but two comments. Mr. Harrison had this letter before him when ho wrote his statement. Does the reader find that his statement produced an impression anything like that which my letter produces? The other comment is this. Asking whether I have any share in the profits, Mr. Harrison not only by this, but by his title, " A New Form of Literary Piracy," tacitly suggests that CONCERNING THE SUPPRESSED BOOK. 437 I have. Merely stating that the affair is purely the affair of the Messrs. Apple- ton, and that not even a thought about money ever entered my head concerning it, I draw attention to the readiness with which Mr. Harrison, without a particle of evidence, makes grave insinuations. And I do this because it will enable the reader to judge what need there probably was for taking the measures I did to prevent the wider and more permanent diffusion of Mr. Harrison's misrepre- sentations. Concerning the newspaper extract describing a Comtist service I know nothing, and greatly regret that it was appended. I will at once ask to have it withdrawn. If three gentlemen, appointed in the usual way, decide that under the circumstances, as stated to me by Professor Youmans, I was not justified in the course I took, I will, if Mr. Harrison wishes it, request Messrs. Appleton to suppress the book and destroy the stereotype plates, and I will make good their loss to them. I am, faithfully yours, HERBERT SPENCER. May 29. [Times, June 2d.~\ MR. SPENCER AND MR. HARRISON. To the Editor of the Times. Sir : I will not pursue this matter further, nor will I insist on Mr. Spencer's fair offer to submit it to arbitration. It satisfies me if he will not claim any absolute and moral right to copyright in America my writings with rectifications of his own. I am accustomed to unauthorized reprints of what I write ; and as I hear there is a brisk sale for these essays {quorum pars minima fui) I will only congratulate the Yankee editor on his 'cuteness. As Mr. Spencer, by his offer, now admits it to be possible that he made a mistake, I am ready to regard his share of it as an inadvertence. I know too well his great generosity in money matters to suppose that any question of profit crossed his mind. But it certainly crossed some one's mind ; and I referred to it only to convince him that eager partisans had led him into a mistake. It is not easy at any time to get him to see this, and to open his eyes I used for once plain words. Conscious that I had conducted a philosophical debate with an old friend with all the deference and admiration that I really feel for his genius, it did pain me to find myself treated as the proverbial dog whom any stick is good enough to beat. The only arbi- tration I now desire is that of some common friend who may convince him that I wish nothing more than a return to the position of philosophic friends who agree to differ about their respective systems. I am, &c, June 1. FREDERIC HARRISON. [Times, June 3d.] MR. SPENCER AND MR. HARRISON. To the Editor of the Times. Sib : Rather than have any further question with Mr. Harrison, and rather than have it supposed that I intentionally ignored his copyright claim, I have telegraphed to Messrs. Appleton to stop the sale, destroy the stock and plates, and debit me with their loss. I am, faithfully yours, Clovelly, June 2. HERBERT SPENCER. 438 THE POPULAR SCIENCE MONTHLY. [ Times, June £lh ] MR. SPENCER AND MR. HARRISON. To the Editor of the Times. Sie : Allow me to supplement my letter telegraphed yesterday, partly to ex- plain how the thing arose, and partly to correct an impression made by your leader of to-day. I was wrong in assenting to the re-publication by Messrs. Ap- pleton. I ought to have borne passively the threatened evils of re-publication by other publishers, and, as my friend has been connected with publishing in New York for thirty years, I supposed his impression that these were coming was correct. But my decision was made in a hurry, without due thought. Believ- ing there was no time to lose, I telegraphed reply, and by the next post indicated corrections to be made in the statements of my views. And here I wish to point out that the notes I indicated were not criticism of Mr. Harrison's opinions, but corrected versions of my own. Any others, if there are any, are Professor You- mans's. I go on to explain that my mind was so engrossed with the due presen- tation of the controversy that the question of copyright never occurred to me ; and the thought that Mr. Harrison might not like his articles republished was excluded by the impression given me that others would republish them if the Appletons did not. Hence my error. But my error does not, I think, excuse Mr. Harrison's insult. By cancelling the rest of the edition and the plates I have done all that remains possible to rectify the effects of my mistake. I am, faithfully yours, Ilfracombe, June 3. HERBERT SPENCER. o [Times, June 6th.~\ MR. HARRISON AND MR. SPENCER. To the Editor of the Times. Sir : May I once more trespass on your space by asking you to publish the following letter from Mr. Harrison ? I am, faithfully yours, HERBERT SPENCER. " 38, "Westbourne-terrace, W., June 4, 1885. Dear Mr. Spencer : As you still appear to think (in spite of my public dis- claimer) that I have brought against you a charge of desiring money profit out of this American reprint, I beg to say that I did not intend to make any such charge, and I do not believe that I have. I regret the use of any words which produced that impression on you. " I am, yours faithfully, Frederic Harrison. " P. S. — You can use this letter as you think fit. " Herbert Spencer, Esq." [Standard, June 10th.'] MR. SPENCER AND MR. HARRISON. To the Editor of the Standard. Sir : The fact that the information to which it refers came through The Standard must be my excuse for asking you to publish the following letter, a copy of which I have inclosed to Mr. Harrison, requesting him to post it after reading it. I am, Sir, your obedient servant, HERBERT SPENCER. CONCERNING THE SUPPRESSED BOOK. 439 " 38, Queen's-gardens, Bayswater, Loudon, W., June 9. " My dear Youmans : I returned borne last night, and only this morning learned that in The Standard of Saturday last there was, in a telegram from New York, a statement to the effect that Messrs. Appleton decline to destroy the stock and plates of the reprinted controversy (as I had telegraphed them to do), on the score that the book would be reprinted by some other publisher. In this expectation they are probably right. But a reprint would necessarily be without the notes ; since these, as implied in your preface, are your copyright in America. Now, though these notes — or, at least, those which I pointed out as needful — are corrections of erroneous statements of my views, yet, rather than have it supposed that I wished to take any advantage of Mr. Harrison in making such corrections, I will submit to the evil of re-issue by another pub- lisher without them ; and I therefore repeat my request that the stock and stereo plates may be destroyed, and the loss debited to me. " One word respecting the proposal of the Appletons to share the author's profits between Mr. Harrison and myself. If any have at present accrued, or if, in consequence of refusal to do as I have above requested, any should hereafter accrue, then I wish to say that having been, and being now, absolutely indiffer- ent to profit in the matter, I shall decline to accept any portion of the returns. " Ever sincerely yours, " Herbert Spencer." Several points in this correspondence, especially in its opening let- ter, require some notice in this place ; but, before making the critical corrections that seem to be required, I desire to say a few words on the peculiar circumstances of American publication which have an im- portant bearing on the present case. Mr. Frederic Harrison took offense at the American reprint in a book of some review articles of his, and pronounces it " a case of piracy." The organs of English opinion, in commenting upon these letters, take the same view. The London " Times," after referring to the graceful and honorable termination of the disagreeable difference between Mr. Harrison and Mr. Spencer, devotes a leading editorial to the discussion of American piracy on the basis of the fresh and strik- ing illustration of it here afforded. Speaking of the effect of the " tolerably rigid copyright law " of England, the " Times " says : " But so far as America is concerned it is different. To the English author that country seems to answer very much to Hobbes's idea of a state of nature. Foreign authors are fair prey ; for them there is or need be no selling or buying of copyrights, and a good book is to be dealt with as a part of the common elements of nature. If any laws govern the matter, it is only those which regulate the capture and re- duction into possession of wild animals." The case is certainly bad enough, but this is an exaggeration. At the outset I admit that on the question of international copy- right, or the claims of foreign authors to property in their books, the English are right and the Americans wrong, so flagrantly wrong as to justify much of the denunciation we receive. The position of our Gov- 44° THE POPULAR SCIENCE MONTHLY. ernment upon the subject I regard as wholly indefensible. Its policy is an outrage upon a class of men who are public benefactors, a dis- grace to the country, and a scandal to civilization. Grover Cleve- land's republic does not recognize that Frederic Harrison and Her- bert Spencer have any right of property in the products of their brain- work. Their productions when brought to the United States belong neither to them nor to anybody else. They are not protected by law, and may be appropriated by anybody without violation of law. There are many in this country who realize the vice of this policy quite as vividly as the foreign victims of it, and who are laboring hard to put an end to it. But, without offering a word of apology for it, there is still something to be said in behalf of those who are compelled to act under a bad state of things which they reprobate, but are for the time powerless to remedy. It is certainly unjust to involve these in the indiscriminate condemnation of the vicious system. It is a good deal easier to denounce it at a distance than to fight it on the spot. Nor is it possible for authors, living under a government which so stringently protects them that they acquire the habit of regarding literary prop- erty as something peculiarly sacred, to fully appreciate the difficulties of publication and the course which business must take under entirely opposite circumstances, where literary property is without any legal protection. With no international copyright it is certainly impossible to act as if we had one. That the Government does not protect him, and that if protected at all it must be done by himself, is the first and vital fact that has to be taken into account when any publisher makes the venture of reissuing a foreign book in this country. The Gov- ernment is, in fact, his enemy, and virtually calls upon everybody to make war upon him. However disposed he may be to treat a foreign author well, to bring out his work in respectable shape, and pay him for it fairly, he meets this ugly circumstance at the threshold of the transaction, that the money he puts into it may be sunk because anybody can reprint the work in cheaper form and without paying the author anything. Nor is this all : the more hon- orable he is, the worse it is for him. Any sense of liberality he may indulge works directly against him. If he publishes the book in good form, pays a decent royalty, and makes it properly known by adver- tising, all this is a temptation to other parties to take advantage of his outlay, and the reputation the book acquires by means of it, to fill the market with mean editions that kill the honest publication. The American publisher is therefore compelled to adopt a policy very dif- ferent from that in England, where books are vigilantly and effectively protected by law. He has to conform to the necessities of a lawless state of things, and must be left to make the best he can of it. But the indiscriminate charges of the London " Times " are not true; all American publishers are not freebooters and pirates. Although it is not possible for them to treat foreign authors with full justice in CONCERNING THE SUPPRESSED BOOK. 441 the absence of international copyright, yet it is false that these au- thors are preyed upon in the unqualified way asserted by the " Times." There are, of course, American publishers, and plenty of them, who are thoroughly unscrupulous ; but there are others, and they are not a few, who do the best they can under the present demoralizing system to compensate foreign authors for their work. They pay them by voluntary arrangement, not the rates that they are accustomed to at home, and not always perhaps as much as they might, but often, as I happen to know, to their own loss, when books are reprinted by others and the market supplied by degraded editions on which the author receives nothing. In the absence of an international copyright law, this voluntary action of American publishers is the only thing practi- cable or possible to mitigate the barbarism of the situation. Imper- fect as it may be, it is an honest procedure in behalf of the foreign author ; and it is now practiced to an extent that should materially qualify those wholesale charges of piracy. The present case is to be regarded in the light of these considerations ; and I think it will be found that the lesson to be drawn from it is quite different from that which has been drawn by the English press. So far as the above correspondence is concerned, the motives that impelled me to take the share I had in bringing out the suppressed book are to be gathered only from a scrap in a hurried private letter to Mr. Spencer ; but, as my act is now branded as piratical, I must be excused for stating more fully the reasons by which I was actually in- fluenced in the course taken. Mr. Harrison had an important controversy with Herbert Spencer on a grave subject, which was published in the "Nineteenth Century." In printing their papers I have the right to assume their purpose to be that they should be read as widely as possible. There was much in- terest in this country to follow this discussion, and we accordingly printed the articles in "The Popular Science Monthly." But, when the controversy was finished, there was a call for its re- publication in a separate form, more convenient, accessible, and cheaper than in the pages of a magazine. The demand was reasonable, and I was anxious to comply with it, that the discussion might be dissemi- nated as widely as possible. I, moreover, desired the republication for the same reason that I had urged Mr. Spencer to go on with the con- troversy with Mr. Harrison. Although knowing the low state of his working-power, and how important it was that he should not be inter- rupted by such side-issues in the prosecution of the great philosophi- cal work upon which he has been engaged for many years, it seemed to me of greater importance that he should seize the opportunity offered by Mr. Harrison's attack to develop more fully his fundamental religious opinions. He had published but little upon that subject for a long time, his views had been much controverted and much misunder- 442 THE POPULAR SCIENCE MONTHLY. stood, and I knew there was a strong desire on the part of many to read everything he might say in further interpretation and elucida- tion of them. His distinctive doctrines were now vigorously and formally attacked by a sagacious adversary, loDg prepared by his spe- cial studies to put them to the severest test. For the same reason that I encouraged Mr. Spencer to give time to the discussion, I desired that his readers in this country should be put in ready possession of it when done. I may add that in this I was impelled by the same gen- eral motives that had prompted me for many years to do what I could to bring Mr. Spencer's ideas before the American people. But there were special reasons which made me wish that the publi- cation should be issued by D. Appleton & Co. This house had printed all of Spencer's works ; and as a present statement of his religious views would be an important addition to them, and would naturally be called for in connection with them, it seemed important that his controversy with Harrison should be brought out in a reputable and permanent shape to take its place with his other books. Besides, there was a high degree of certainty that the discussion would be published by somebody. The names of the eminent contestants, and the interest felt by a large number of people in the subject, were evineed by a strong demand for the publication. The discussion in its separate form was called for by the friends of Mr. Harrison and by the friends of Mr. Spencer, and by others who were friends of nei- ther. It was open to anybody to print it, and there was every proba- bility that it would be picked up and issued in a cheap, catchpenny edition, which is now so common with publications of every kind. I desired, therefore, that the Appletons should bring it out in a respect- able shape, and at a moderate price, that the book might be had at any time in a form suitable for preservation. I protest that these considerations were not vitiated by any covet- ous desire or purpose whatever. Mr. Harrison says it is a case of "piracy"; but, so far as this involves the taking of his property without compensation, there was no thought of it. In his opening letter he virtually accused Mr. Spencer of collusion in the piracy of his articles, from a sordid intention. Judged by this extraor- dinary letter, Mr. Harrison's religion of humanity consists chiefly in imputing vile motives to his fellow-men. He said, "May I ask if it is proposed to hand you the profits of a book of which I am (in part) the author, or are these to be retained by your American pub- lishers and friend ? " Evidently the pecuniary consideration was up- permost in his own mind. But he had here gone too far. Every- body recognized the outrage. The reader will note the striking dif- ference in tone, amounting to a collapse, between his first and his second letters. He withdrew the offensive insinuation so far as Mr. Spencer was concerned, saying, " I know too well his great generos- ity in money matters to suppose that any question of profit crossed CONCERNING THE SUPPRESSED BOOK. 443 his mind." But he knew this no better when he wrote his second let- ter than when he wrote the first. He sent Mr. Spencer a private note asking explanations about the book, and this Mr. Spencer an- swered, but said nothing respecting the copyright ; this did not enter his mind, probably for the reason that the house which issued it had published his books for twenty-five years, paying him regularly on all of them from the first, and he had no care about it, knowing that the equitable thing would of course be done to all concerned. But the inadvertence gave Harrison his opportunity. But while Mr. Harrison exonerates Mr. Spencer from all thought of making profit out of him, he adds, " But it certainly crossed some one's mind," referring of course to Mr. Spencer's "American publish- ers and friend." Yet there was not the slightest wish or design on the part of the publishers of the book to withhold from Mr. Harrison his proper share in its copyright proceeds. They have published the scientific and philosophical works of many English authors, on which they have paid the customary compensation allowed to American authors, and if Mr. Harrison doubts it he can satisfy himself by in- quiring of his neighbors, Tyndall, Lecky, Huxley, Bain, Sully, or the Darwin s, and there is surely no reason why they should not have com- pensated Mr. Harrison in the same way ; and this was certainly their intention. But perhaps the party who desired to plunder Mr. Harrison (he uses the significant word twice in his first letter) was Mr. Spencer's American friend, and that he supposed this " friend " capable of sharp practice is inferable from his remark, " I will only congratulate the Yankee editor on his 'cuteness." Yet the 'cute Yankee editor in this case was the only party to get nothing. Among the several stools occupied by authors and publishers, it was his fate to sit on the ground. Neither by stipulation nor expectation was he to have a cent for his labor in editing the volume, or his efforts in promoting its cir- culation. The reasons which actuated him have been already stated. But as the question is here raised of venal motives in the treatment of foreign authors, and as this transaction has been extensively pa- raded as a flagitious example of American piracy, the editor of the suppressed book is entitled to say that he has done his full share in a practical way toward promoting international equity in the payment of authors for their books. He gave nearly a year's labor to the organi- zation of the "International Scientific Series" for the avowed pur- pose of securing more satisfactory compensation to scientific writers. The project was based upon the condition of the payment of copy- right to each of the contributors from all the countries in which the books were issued. Nothing of the kind had ever been done or at- tempted before ; and, in regard to its result, Dr. John W. Draper re- marked, " Although there are international copyright regulations in Europe, and my various works have been translated into many foreign 444 THE POPULAR SCIENCE MONTHLY. languages, I have never received anything from them except upon the volume I wrote for the ' International Series,' and on that I have been paid regularly by the English, French, German, and Italian, as well as by the American publishers." Fifty volumes have now appeared in that series, and the American publishers have voluntarily paid all the foreign contributors the same as if they had been citizens of the United States. And this they have done in spite of the fact that this honorable arrangement has been disregarded, and various of the vol- umes have been reprinted in shabby twenty-cent editions, on which, of course, the authors have received nothing. This, then, is the way in which Mr. Harrison has been outraged. He had his articles brought out in good shape for such of his friends as desired to possess them in a separate form. He has been "plun- dered " by being protected against plunder on the part of those who might have issued a trivial and fugitive edition of his controversy, and allowed him nothing for it. He has been " pirated " by having volun- tarily secured for him the substantial benefits of an international copy- right law. But Mr. Harrison's articles were used without his consent, and that is what the charge of " piracy" here amounts to. His consent was not asked, because it would have implied control of that over which he had no control. If he had refused, that would not have stopped the publication, but would have simply defeated the purposes of those who knew better than Mr. Harrison did what required to be done. He was not consulted for the simple reason, now obvious enough, that he would be unlikely to make allowance for a state of things utterly different from that to which he has been accustomed. He was not asked, be- cause, while his assent would have done no good, his dissent would have done injury to himself, to Mr. Spencer, and to the public. And that Mr. Harrison would have withheld his consent is far from im- probable. That the book was wanted here by many readers was nothing to him, as is shown by the fact that, when a word would have saved it from destruction, he declined to utter it. Something is of course due to courtesy, but I was not at all certain that courtesy would be met in the same spirit. The feeling of high-toned British authors toward American " pirates " is not usually vented in gracious expression. American experience with such authors is apt to en- gender diffidence in approaching them. Those gentlemanly and honorable publishers, the Messrs. Putnam, having special reasons re- cently to make overtures to Mr. Ruskin for the use of one of his arti- cles (to be paid for, of course), were deterred from doing so because that author " absolutely declined to come into any relation with an American publisher." Mr. Harrison is understood to be a particular and punctilious man, and that he can, upon occasion, pretermit the requirements of amiable civility, and take to "plain words," is amply attested by his letter of May 29th to Herbert Spencer. CONCERNING THE SUPPRESSED BOOK. 445 But, in the matter of " piracy," it is Mr. Spencer who comes in for Harrison's hottest indignation. He accuses him of having invented a new form of it, and aggravated the offense by its clandestine perpe- tration. Now, let us see what it was that Spencer did. After finish- ing the controversy in the "Nineteenth Century," Mr. Harrison trans- ferred it to the "Pall Mall Gazette," in which he printed an additional article, addressed to a new audience, and filled with very objectionable misstatements. It would not do, in editing the volume which was in- tended to be a full presentation of the discussion, to leave this article out. But to print it without corrections would be unjust to Spencer, and to the readers of the book, who wanted and were entitled to the completest statement of the case. There was no call for anything more from Mr. Harrison, who had had his last word, and declared that he should pursue the controversy no further ; but there was a need that corrections by Spencer should be supplied. He accordingly sent me the substance of some additions to be appended as notes, and which I inserted in their appropriate places. I deny the wrongfulness of this act, and the ado that has been made over it seems to me perfectly absurd. Mr. Spencer did what it was desirable and entirely proper that he should do. He had not only the right but it was his duty to defend himself against the erroneous representations of Mr. Harrison ; and I insist that, if any apology was due either way, it was from Mr. Harrison to Spencer for making the misstatements, rather than from Spencer to Harrison for correcting them. Mr. Spencer, as will be seen, prints two paragraphs from a private letter of mine giving reasons which induced him to favor the American reprint, and Mr. Harrison characterizes them as chiefly " inventions." I had said, " Harrison is coming over to lecture in this country," and Mr. Harrison says he never thought of it. I wrote carelessly ; but my meaning was, that he is expected to come, and in this there was no " in- vention." It had been talked about, and there was nothing unlikely in it. The coming of eminent Englishmen to this country to lecture is certainly no unusual thing. Mr. Harrison is a lecturer, a man of ideas which he is interested in propagating, and is reputed to have means and leisure. He has many admirers in the United States, and a reputation which would be certain to secure him good audiences. As it turns out, " the wish was father to the thought," but the rumor was not improbable. I should have referred to it as a contingency, and I simply meant that it might be worth taking into account, with reference to the publication of the controversy. Mr. Harrison says the idea that there was any danger of republica- tion in this country by his friends rested also upon pure "invention." But I did not say this. I wrote to Spencer, " There is danger that it will be done by others, and if that should occur it would be construed as a triumph of the Harrison party." Mr. Spencer's interpretation of it was, "I had to choose between republication by my American 446 THE POPULAR SCIENCE MONTHLY. friends or republication by your friends, with the implication that I was averse to it." And Mr. Spencer was here substantially right. Although there may have been no apprehension that Mr. Harrison's avowed friends would move in reprinting the book, yet, if it had been done by anybody but the Appletons, the inevitable inference would have been that their author had been so badly handled that they de- clined to back him. The book was looked for from Mr. Spencer's publishers, they had printed it in their magazine, they issued all his works, there was a demand for the volume which was certain to make it a safe business venture, and it represented two sides or schools of thought : if, under all these circumstances, D. Appleton & Co. had left the work for others to publish, the certain construction would have been that the book was abandoned to the party opposed to Mr. Spencer. This is the aspect of the case which he had to meet, and it is not at all affected by Mr. Harrison's statement that his friends had no idea of printing the controversy. Another explanation seems here called for. Those who will refer to the second paragraph of my letter, quoted by Mr. Sjiencer, will observe both an indecision and a confusion in the statement. This was due, not only to hasty writing, but to some perplexity in my own mind. I said, " If I thought no one else would print the correspond- ence " (conti'oversy), " I should be in favor of our not doing it " ; and I then go on to give reasons for this conclusion, ending with the remark, " On the whole, it may be politic to reprint." Apparently this indif- ference to publication is inconsistent with the various reasons I have given for strongly desiring it. But there was a consideration not men- tioned in the letter which weighed much with me at the time. I was in very bad health, and was urged by physicians and friends to go South without delay. It seemed therefore to be impracticable, if not impossible, for me to give that attention to the editing and publication of the volume which were prompted by my interest in it. But it will be noticed that, under this conflict of inclinations, though I gave some trivial reasons for non-publication, the conclusion favors reprinting. This shows the predominant feeling, even in a time of depression ; and I must say, as a matter of fact that, though referring the matter as I did in a hurried note to Mr. Spencer, I had not for a moment really relinquished the purpose of bringing out the book. This ex- planation is necessary, that the responsibility may rest where it prop- erly belongs. Mr. Harrison lays stress upon Spencer's agency in " promoting and assisting " in the production of " a volume for which you are responsible, and which you have authorized and adopt." But though Mr. Spencer chose to take the responsibility because he had assented to it, and furnished some notes for it, yet it was neither by his suggestion, procurement, nor desire that the book was issued ; and truth requires me here to say that, if he had discouraged or even opposed it, the book would probably have been reprinted by D. Appleton & GENIUS AND INSANITY. 447 Co. all the same. Mr. Spencer had, in reality, very little to do with the edition. For the Introduction, the had taste with which the notes were embellished, and the newspaper quotation describing the doings in a branch of the positivist church in London which Mr. Har- rison does not like, he is not to be held to account. For his offense in correcting some injurious misrepresentations in a controversial volume published for the use of a people three thousand miles away, the London " Times " declares that Mr. Spencer has made the amende honorable by destroying the book ; and this is the general English view. The equally general American view is, that this ex- treme proceeding was ridiculous, that it benefited nobody, and gratui- tously deprived many readers in this country of a valuable work on an important subject. It is, at any rate, desirable that the responsi- bility for this result should be fixed where it justly belongs. Mr. Spencer made two proposals to Harrison looking to the preservation of the work, both of which were absolutely fair, but neither of which was accepted. Mr. Spencer would have been justified in making a stand upon either of these propositions, and refusing further conces- sions ; but Mr. Harrison's rejection of his overtures left the matter in so unsatisfactory a shape that nothing remained for Mr. Spencer but to cut the knot by ordering the book suppressed. GENIUS AND INSANITY. By JAMES SULLY. THE problems which have so long perplexed the thoughtful mind in presence of that dark yet fascinating mystery, the nature and origin of genius, have recently propounded themselves with new stress and insistence. Whatever may be said against Mr. Froude's neglect of the pruning-knife in publishing Carlyle's " Journals and Letters," the psychologist at least will be grateful to him for what is certainly an unusually full and direct presentment of the temperament and life of genius. Here we may study the strange lineaments which stamp a family likeness on the selected few in whose souls has burned the genu- ine fire of inspiration. These memoirs disclose with a startling distinct- ness the pathetic as well as the heroic side of the great man. In Car- lyle we see the human spirit in its supreme strength jarred and put out of tune by the suffering incident to preternaturally keen sensi- bilities and an unalterably gloomy temperament. In this strange record, too, we find ourselves once more face to face with what is perhaps the most fascinating of the fascinating prob- lems surrounding the subject of intellectual greatness, that of its rela- tion to mental health. Carlyle compels the attentive reader to pro- pound to himself anew the long-standing puzzle, " Is genius something 448 THE POPULAR SCIENCE MONTHLY. wholly normal and sane ? " For there is surely a suggestion of tem- porary mental unsoundness in the idea of that lonely wanderer through the crowded streets of London suddenly seeing in the figures he met so many specters, and feeling himself to be but another "ghastly phantom haunted by demons." And, if all anger is a sort of madness, it is but natural that one should see something of a momentary mania in those terrible outbursts of a spirit of revolt against all things which now and again made desolate the Chelsea home, and wrung from the sage's wife the humiliating confession that she felt as if she were " keeper in a madhouse." The idea that there is an affinity between genius and mental dis- ease seems at first foreign to our modern habits of thought. In the one, we have human intellect rejoicing in Titanic strength ; in the other, that same intellect disordered and pitiably enfeebled. Yet, as has been hinted, the belief in the connection of the two is an old and persistent one. In truth, the common opinion has always gravitated toward this belief. A word or two may make this clear. To the multitude of men genius wears a double aspect. Superla- tive intellectual endowment is plainly something very unlike the ordi- nary type of intelligence. The relation of lofty superiority includes that of distance, and mediocrity in viewing the advent of some new spiritual star may adopt either the one or the other manibre de voir. Which aspect it will select for special contemplation depends on cir- cumstances. In general it may be said that, since the recognition of greatness presupposes a power of comprehension not always granted to mediocrity, the fact of distance is more likely to impress than the fact of altitude. It is only when supreme wisdom has justified itself, as in the predictions of the true prophet, that its essential Tightness is seen by the crowd. Otherwise the great man has had to look for rec- ognition mainly from his peers and the slightly more numerous com- pany of those whose heads rise above the mists of contemporary pre- judice. It is easy to see that this vulgar way of envisaging genius as marked divergence from common-sense views of things may lead on to a con- demnation of it as a thing unnatural and misshapen. For, evidently, such divergence bears a superficial likeness to eccentricity. Indeed, ' as has been well said, the original teacher has this much in common with the man mentally deranged, that he " is in a minority of one " ; and, when pains are not taken to note the direction of the divergence, originality may readily be confounded with the most stupid singular- ity ; and, further, a cursory glance at the constitution of genius will suffice to show that the originator of new and startling ideas is very apt to shock the sense of common men by eccentricities in his manner of life. A man whose soul is being consumed by the desire to dis- cover some new truth, or to give shape to some new artistic idea, is exceedingly liable to fall below the exactions of conventional society GENIUS AND INSANITY. 449 in the matter of toilet and other small businesses of life. Among the many humorously pathetic incidents in the records of great men, there is perhaps none more touching than the futile attempt of Beethoven to dress himself with scrupulous conformity to the Viennese pattern of his day. In contradistinction to this disparaging view, the admiring contem- plation of the great man as towering above minds of ordinary stature seems directly opposed to any approximation of the ideas of genius and mental disorder. And this has undoubtedly been in the main the tendency of the more intelligent kind of reverence. At the same time, by a strange, eddy-like movement in the current of human thought, the very feeling for the marvelousness of genius has given birth to a theory of its nature which in another way has associated it with men- tal aberration. I refer to the ancient doctrine of inspiration as devel- oped more particularly in Greece. It may be worth while to review for a moment the general course of thought on this dark subject. In the classic world, preternatural intellectual endowments were, on the whole, greeted with admiration. In Greece more particularly, the fine esthetic sense for what is noble, and the quenchless thirst for new ideas, led to a revering appreciation of great original powers.* The whole manner of viewing such gifts was charged with supernatu- ralism. As the very words employed clearly indicate, such fine native endowment was attributed to the superior quality of the protective spirit (Sai'/xwv, genius) which attended each individual from his birth. We see this supernaturalism still more plainly in the Greek notion of the process of intellectual generation. The profound mystery of the process, hardly less deep than that of physical generation, led to the grand supposition of a direct action of the Deity on the productive mind. To the Greeks the conception of new artistic ideas implied a possession (Karo^) of the individual spirit by the god. Now, it might naturally occur to one that such an inundation of the narrow confines of the human mind by the divine fullness would produce a violent disturbance of its customary processes. It was a shock which agitated the whole being to its foundation, exciting it to a pitch of frenzy or mania. The poet was conceived of as infuriated or driven mad by the god ; and a somewhat analogous effect of di- vine intoxication was recognized by Plato as constituting the essence of philosophic intuition. f Hence Greek and Roman literature abounds with statements and expressions which tend to assimilate the man of genius to a madman. The " furor poeticus " of Cicero and the " ama- bilis insania " of Horace answer to the Oela pavta of Plato. And to * Socrates is perhaps only an apparent exception, for the odium he excited seems to have been due to the essentially critical and destructive character of his mission. f See the memorable passage in the " Phadrus," p. 244 a, etc. Plato went so far as to suggest that the name navris, seer, was derived from ^aipofxai, to rage or be mad. vol. xxvii. — 29 450 THE POPULAR SCIENCE MONTHLY. the more scientific mind of Aristotle it appeared certain (according to Seneca) that there was no great intellect {magnum ingenium) without some mixture of madness {dementias). It must be remembered, however, that in the eyes of the ancients genius was hardly degraded by this companionship with madness. Men had not yet begun to look on insanity as one of the most pitiable of maladies. So far from this, it was a common idea that the insane were themselves inspired by the action of deity. We have a striking illustration of the absence even among the educated Greeks of the mod- ern feeling toward madness in the fact that Plato was able to argue, with no discoverable trace of his playful irony, that certain sorts of madness are to be esteemed a good rather than an evil.* The influence of Christianity and of the Church served at first to brand mental derangement with the mark of degradation. The doc- trine of possession now assumed a distinctly repellent form by the in- troduction of the Oriental idea of an evil spirit taking captive the human frame and using it as an instrument of its foul purposes. The full development of this idea of demoniacal possession in the middle ages led, as we know, to many cruelties. And, though Christianity showed its humane side in making provision for the insane by asylums, the treatment of mental disease during this period was, on the whole, marked by much harshness. f This debasement of the idea of madness had, however, no appre- ciable effect in dissolving the companionship of the two ideas in popu- lar thought. For the attitude of the Church was, for the most part, hostile to new ideas, and so to men of original power. In sooth, we know that they were again and again branded as heretics, and as wicked men possessed by the devil. And thus genius was attached to insanity by a new bond of kinship. The transition to the modern period introduces us to a new concep- tion both of genius and of insanity. The impulse of inquisitiveness, the delight in new ideas, aided by the historical spirit with its deep sense of indebtedness to the past, have led the later world to extol intellectual greatness. We have learned to see in it the highest product of Nature's organic energy, the last and greatest miracle of evolution. On the other hand, the modern mind has ceased to see in insanity a supernatural agency, and in assimilating it to other forms of disease has taken up a humane and helpful attitude toward it. Such a change of view might seem at first to necessitate a sharp severance of the new ideas. For, while it places genius at the apex of * " Phaedrus," he. cit. Mr. Lecky points out that the Greeks had no asylums for the insane (" History of European Morals," vol. ii, p. 90). On the other hand, Dr. Maudsley tells us that Greek scientific opinion on the subject was an anticipation of modern ideas (" Responsibility in Mental Disease," p. 6). \ See Lecky, op. cit., vol. ii, p. 92, etc. ; cf. Maudsley, op. cit., p. 10. GENIUS AND INSANITY. 451 evolution, it reduces madness to a form of disintegration and dissolu- tion. Nevertheless, we meet in modern literature with an unmistak- able tendency to maintain the old association of ideas. Genius is now recognized as having a pathological side, or a side related to mental disease. Among our own writers we have so healthy and serene a spirit as Shakespeare asserting a degree of affinity between poetic creation and madness : * " The lunatic, the lover, and the poet, Are of imagination all compact," etc. Midsummer- Night' 's Dream, act v, sc. 1. A more serious affirmation of a propinquity is to be found in the well- known lines of Dryden : " Great wits are sure to madness near allied, And thin partitions do their bounds divide." * As might be expected, French writers, with their relish for pun- gent paradox, have dealt with special fullness on this theme. " Intinis esprits," writes Montaigne on a visit to Tasso in his asylum, " se trouvent ruinez par leur propre force et soupplesse." Pascal observes that " l'extreme esprit est voisin de l'extreme f olie." In a similar strain Diderot writes : " Oh ! que le genie et la folie se touchent de bien pres ! " The French writer who most distinctly emphasizes the propo- sition is Lamartine. "Le genie," he observes in one place, "porte en lui un principe de destruction, de mort, de folie, comme le fruit porte le ver " ; and again he speaks of that " maladie mentale " which is called genius. In German literature it is Goethe, the perfect ideal, as it would seem, of healthy genius, who dwells most impressively on this idea. His drama, "Tasso," is an elaborate attempt to uncover and expose the morbid growths which are apt to cling parasitically about the tender plant of genius. "With this must be mentioned, as another striking literary presentment of the same subject, the two eloquent passages on the nature of genius in Schopenhauer's opus magnum. Against this compact consensus of opinion on the one side we have only a rare protest like that of Charles Lamb on behalf of the radical sanity of genius, f Such a mass of opinion can not lightly be dismissed as valueless. It is impossible to set down utterances of men like Diderot or Goethe to the envy of mediocrity. Nor can we readily suppose that so many penetrating intellects have been misled by a passion for startling paradox. We are to remember, moreover, that this is not a view of the great man ab extra, like that of the vulgar already referred to ; it is the opinion of members of the distinguished fraternity themselves who are able to observe and study genius from the inside. * "Absalom and Achitophel," part i, line 163. f See his essay, " Sanity of True Genius," in the " Last Essays of Elia." 452 THE POPULAR SCIENVE MONTHLY. Still, it may be said, this is, after all, only unscientific opinion. Has Science, with her more careful method of investigating and prov- ing, anything to say on this interesting theme ? It is hardly to he supposed that she would have overlooked so fascinating a subject. And, as a matter of fact, it has received a considerable amount of attention from pathologists and psychologists. And here for once Science appears to support the popular opinion. The writers who have made the subject their special study agree as to the central fact that there is a relation between high intellectual endowment and mental derangement, though they differ in their way of defining this relation. This conclusion is reached both inductively by a survey of facts, and deductively by reasoning from the known nature and conditions of great intellectual achievement on the one hand, and of mental disease on the other.* What we require first of all is clearly as many instances as can be found of men of genius who have exhibited intellectual or moral pe- culiarities which are distinctly symptomatic of mental disease. Such a collection of facts, if sufficient, will supply us with a basis for induc- tion. In making this collection we need not adopt any theory respect- ing the nature either of genius or of mental disease. It is sufficient to «ay that we include under the former term all varieties of originative power, whether in art, science, or practical affairs. And as to the latter term, it is enough to start with the assumption that fully devel- oped insanity is recognizable by certain well-known marks ; and that there are degrees of mental deterioration, and a gradual transition from mental health to mental disease, the stages of which also can, roughly at least, be marked off and identified. In surveying the facts which have been relied on by writers, we shall lay most stress on mental as distinguished from bodily or nervous symptoms. And of these we may conveniently begin with the less serious manifestations : 1. The lowest grade of mental disturbance is seen in that tempo- rary appearance of irrationality which comes from an extreme state of " abstraction " or absence of mind. To the vulgar, as already hinted, all intense preoccupation with ideas, by calling off the attention from outer things and giving a dream-like appearance to the mental state, is apt to appear symptomatic of " queerness " in the head. But in order that it may find a place among distinctly abnormal features this absence of mind must attain a certain depth and persistence. The ancient story of Archimedes, and the amusing anecdotes of Newton's * The principal authoritative utterances on the subject are Moreau, " La Psychologie morbide," etc. ; Hagen, " Ueber die Verwandtschaft des Genies mit dem Irresein " (" Zeitschrift fur Psychiatrie," Band 33) ; and Radestock, " Genie und Wahnsinn (Breslau, 1884). This last contains the latest review of the whole question, and is written in a thoroughly cautious scientific spirit. I have derived much aid from it in preparing this essay. GENIUS AND INSANITY. 453 fits, if authentic, might be said perhaps to illustrate the border-line between a normal and an abnormal condition of mind. A more dis- tinctly pathological case is that of Beethoven, who could not be made to understand why his standing in his night attire at an open window should attract the irreverent notice of the street boys. For in this case we have a temporary incapacity to perceive exterior objects and their relations ; and a deeper incapacity of a like nature clearly shows itself in poor Johnson's standing before the town clock vainly trying to make out the hour. This same aloofness of mind from the external world betrays itself in many of the eccentric habits attributed to men and women of genius. Here, again, Johnson serves as a good instance. His incon- venient habit of suddenly breaking out with scraps of the Lord's Prayer in a fashionable assembly marks a distinctly dangerous drift- ing away of the inner life from the firm anchorage of external fact. In the cases just considered we have to do with a kind of mental blindness to outer circumstances. A further advance along the line of intellectual degeneration is seen in the persistence of vivid ideas, commonly anticipations of evil of some kind, which have no basis in external reality. Johnson's dislike to particular alleys in his London walks, and Madame de Stael's bizarre idea that she would suffer from cold when buried, may be taken as examples of these painful delusions or idees fixes. A more serious stage of such delusions is seen in the case of Pascal, who is said to have been haunted by the fear of a gulf yawning just in front of him, which sometimes became so overmaster- ing that he had to be fastened by a chain to keep him from leaping forward. It is plain that in this last case we touch on the confines of sense- illusion. It is probable that hallucinations may occur as very rare experiences in the case of normal and healthy minds. Yet, though not confined to states of insanity, illusions of the senses are commonly, if not always, indicative of at least a temporary disturbance of the psycho-physical organism. And we have on record a considerable number of instances of eminent men who were subject to these decep- tions. It is not only the religious recluse, with his ill-nourished body, and his persistent withdrawal from the corrective touch of outer things, who experiences them. Luther was their victim as well as Loyola. Auditory hallucinations — that is, the hearing of imaginary voices — appear to have occurred to Malebranche and Descartes, as they cer- tainly did to Johnson. The instances of visual hallucinations are per- haps more numerous still. Pope, Johnson, Byron, Shelley, are said to have had their visions. Even so strong and well-balanced a mind as Goethe was not exempted. Nor has the active life of the soldier always proved a safeguard. The stories of the prognostic visions of Brutus and other generals of the old world are well known. Among 454 THE POPULAR SCIENCE MONTHLY. modern ones, Napoleon is said to have had recurring visits from his guardian spirit or genius. In the abnormalities just touched on, disturbance of intellectual function is the chief circumstance, though an element of emotional disturbance is commonly observable as well. In another class of cases this last ingredient becomes the conspicuous feature. By this is meant such an accession of general emotional excitability, and along with this such a hypertrophy and absolute ascendency of certain feelings, as to constitute a distinct approximation to the disorganized psychical state which has been called moral insanity. And here reference may first be made to that violence of temper and that extravagant projection of self and its concerns to the dis- placement of others' claims and interests which might be termed a kind of moral hallucination. How many names in the roll of English writ- ers at once occur to the mind in this connection ! Pope, Johnson, Swift, Byron, to which list must now be added Carlyle, may be taken as typical instances of the genus irritabile vatum. And among foreign deities we have Voltaire and Rousseau, Handel and Beethoven, and even philosophers like Herder and Schopenhauer. Other emotional disorders take on more distinctly the aspect of moral obliquities. And here we have specially to do with poetic genius. Without adopting the slightly contemptuous opinion that poets are, as a rule, a " sensuous, erotic race," one must admit that an untamed wildness of amatory passion has been a not infrequent ac- companiment of fine poetic imagination.* For a clear illustration, however, of the morbid tendency of such irregularities, we must go, not to the comparatively regular life of a Goethe or a Shelley, but to the wild and lawless career of a Rousseau, of whom it was well said by a clever woman, " Quand la Nature forma Rousseau, la sagesse petrit la pate, mais la folie y jeta son levain." To a tempestuous violence of sexual passion there has too com- monly joined itself a feverish craving for physical stimulants ; f and so the pure heavenly flame of genius has again and again had to contend with the foul, murky vapors which exhale from the lower animal nature. No need to tell again the gloomy story of splendid power eaten into and finally destroyed by the cancer of rampant appetite. In our own literature the names of Ben Jonson, Nat Lee, Burns, and others at once occur to the student. Edgar Allan Poe represents the same tragic fatefulness of genius in American letters. Among French- men we have as conspicuous examples Villon and De Musset. Among Germans, Giinther, Burger, and numbers of those about Herder and * Even the spiritual Dante has been found wanting in this matter by no more strait- laced an authority than Boccaccio. f These include not only alcoholic drinks but opium, to the use of which Voltaire, Madame de Stael, Coleridge, and De Quincey, and probably others, were addicted. The excitement of gambling seemed in Lessing's case to fill the place of physical stimulants. GENIUS AND INSANITY. 455 Goethe in the turbulent times of the Sturm und Drang, and Hoff- mann, the novelist, suffered the same moral shipwreck. 2. We may now pass to another class of cases in which the patho- logical character is still more plainly discernible. Outbursts of fierce passionateness may perhaps be thought by some to be, after all, only marks of a certain kind of robust vitality. But no one will say this of the gloomy depression, the melancholy brooding on personal ills, ending sometimes in distinctly hypochondriac despondency, which have not unfrequently been the accompaniment of great intellectual power. It was remarked by Aristotle, who was a long way the shrewdest and most scientific observer of antiquity, that all men of genius have been melancholic or atrabilious.* He instances Empedocles, Socrates, and Plato, and the larger number of the poets. And the page of modern biographic literature would supply many a striking illustration of the same temperament. The pessimism of Johnson, Swift, Byron, and Carlyle, of Schopenhauer and Lenau, of Leopardi and of Lamartine, may perhaps be taken as a signal manifestation of the gloom which is apt to encompass great and elevated spirits, like the mists which drift toward and encircle the highest mountain-peaks. In some cases this melancholy assumes a more acute form, giving rise to the thought and even the act of suicide. Among those who have confessed to have experienced the impulse may be mentioned Goethe in the Werther days, Beethoven during the depression brought on by his deafness, Chateaubriand in his youth, and George Sand also in her early days. The last, writing of her experience, says, " Cette sensation" (at the sight of water, a precipice, etc.) "fut quelquefois si vive, si subite, si bizarre, que je pus bien constater que c'etait une espece de folie dont j'etais atteinte." Johnson's weariness of life was, it seems certain, only prevented from developing into the idea of suicide by his strong religious feeling and his extraordinary dread of death, which was itself, perhaps, a morbid symptom. In some cases this idea prompted to actual attempts to take away life. The story of Cowper's trying to hang himself, and afterward experiencing intense religious remorse, is well known. Another in- stance is that of Saint-Simon, whose enormous vanity itself looks like a form of monomania, and who, in a fit of despondency, fired a pistol at his head, happily with no graver result than the loss of an eye. Alfieri, who was the victim of the " most horrid melancholy," tried on one occasion, after being bled by a surgeon, to tear off the bandage in order to bleed to death. Among those who succeeded in taking away their life are Chatterton, whose mind had been haunted by the idea from early life, Kleist the poet, and Beneke the philosopher. * " Cur homines qui ingenio claruerunt vel in studiis philosophise, vel in republic;! administranda, vel in carmine pangendo, vel in artibus exercendis, melancolicos omnes fuisse videamus ? " Prob. xxx. Aristotle's authority on the point is quoted by Cicero, Tuscul. dlsp., i, 33 ; de divin., i, 88. 456 THE POPULAR SCIENCE MONTHLY. 3. We may now pass to the most important group of facts — namely, instances of men of genius who have suffered from fully developed mental disease. In certain cases this disruption of the organs of mind shows itself in old age, and here, it is evident, we have to distinguish what is known as senile dementia from the impairment of faculty incident to old age. A clear instance of cerebral disease is afforded by the botanist Linnaeus, whose faculties gave way after a stroke. The mental stupor into which the poet Southey finally sank was a similar phenomenon. Swift's fatal disease, the nature of which has only recently been cleared up by science, was cerebral disorganization brought on by peripheral disease in the organ of hearing. Zimmer- mann, the author of the work on " Solitude," who had been a hypochon- driac from the age of twenty, ended his life in a state of melancholy indistinguishable from insanity. The final collapse, under the pressure of pecuniary anxieties, of Scott's cerebral powers, is too well known to need more than a bare mention. Besides these instances of senile collapse, there are several cases of insanity showing itself in the vigorous period of life. Sometimes, as in the instance of Richelieu, who had shown himself an erratic being from his childhood, the madness appeared as a sudden and transient fit of delirium. In other cases the disorder took a firmer hold on the patient. Charles Lamb, Handel, and Auguste Comte suffered from insanity for a time, and had to be put under restraint. Tasso, whose whole nature was distinctly tinged with the " insane temperament," had again and again to be confined as a madman. Donizetti was also for a time insane and confined in an asylum. Among those who became hopelessly insane were the poets Lenau and Holderlin and the composer Schumann, the latter of whom had long been the victim of melancholy and hallucinations, and had before his confinement attempted to drown himself in the Rhine. I have preferred to dwell on the physical aspect of the relation be- tween genius and disease. But no adequate investigation of the sub- ject is possible which does not consider the physical aspect as well. No one now, perhaps, really doubts that to every degree of mental dis- turbance and mental disorganization there corresponds some degree of deterioration and disorganization of the nerve-centers. Psychical dis- turbance and disruption proceed pari passu with physical. This being so, it is pertinent to our study to remark that men of genius have in a surprising number of cases been affected by forms of nervous disease which, though not having such well-marked psychical accompaniments as occur in states of insanity, are known to be allied to these. 4. To begin with, it seems certain that a number of great men have died from disease of the nerve-centers. Among other names may be mentioned Pascal, who had all his life been the victim of nervous GENIUS AND INSANITY. 457 disorders, and who succumbed, at the early age of thirty-nine, to pa- ralysis accompanied by convulsions. Two of the greatest scientific men, Kepler and Cuvier, died, according to Moreau, from disease of the brain. Rousseau was carried off by an attack of apoplexy. Mo- zart's early death was due to brain-disease, showing itself in other ways by morbid delusions, fainting-fits, and convulsions. Another musician, Mendelssohn, succumbed to an attack of apoplexy. Heine's fatal malady, which kept him for seven years a prisoner in his " mat- tress-grave," was disease of the lower nerve-centers in the spinal cord. Other men of genius have suffered from nervous disorders from time to time. Moliere was the subject of recurring convulsions, an attack of which would prevent his working for fifteen days. Alfieri, to whose morbid mental symptoms reference has already been made, suffered when young from a disease of the lymphatic system, and was afterward liable to convulsions. Paganini, the musician, suffered from an attack of catalepsy when four years old, and later on was the vic- tim of recurring convulsions ; and Schiller, who was very delicate from youth, was also the subject of recurring fainting-fits and convulsions. The lesser forms of nervous disorder — headache, malaise, and re- curring periods of nervous prostration — are too common among all brain- workers to call for special notice here. The latest biography of a woman of genius strikingly illustrates this milder form of the pen- alty which mortals have to pay for daring to aspire to the ranks of the immortals. In George Eliot we have one more name added to the list of great ones to whom, to use the words of a French writer, has been granted " le funeste privilege d'entendre crier a toute heure les ressorts de leur machine." 5. One other significant group of facts remains to be touched on. In a considerable number of cases it has been ascertained that insanity or other form of nervous disorder has shown itself in the same family as genius, whether as its forerunner, companion, or successor. Cha- teaubriand's father is said to have died of apoplexy. Schopenhauer's grandmother and uncle were imbecile. Several distinguished men had insane sisters, among others Richelieu, Diderot, Hegel,* and Charles Lamb. One of Mendelssohn's sons became insane, f I have endeavored in this brief review of the alleged facts to give an adequate impression of their variety and range. It now remains to inquire into their precise evidential value. The first question that naturally arises here is whether the facts are well authenticated and accurately presented. A cautious mind will readily reflect that if genius as such is apt to assume an abnormal aspect to average common sense, biographers may easily have invent- * That Hegel's sister was insane and drowned herself is asserted by Moreau, on the authority of an article in the " Revue des Deux Mondes," and quoted by Radestock. f Symptoms of insanity are said by Moreau to have shown themselves in the families of several eminent rulers, including Peter the Great. (See Radestock, p. i,seq.) 458 THE POPULAR SCIENCE MONTHLY. ed, or at least exaggerated, some of the alleged morbid characteristics of the great ; and as a matter of fact there is good reason to suppose that this falsifying of the record of greatness has taken place. I may refer to the story of the madness and suicide of Lucretius, which is ex- tremely doubtful, and may have grown out of a religious horror at the supposed tendency of his writings. The story of Newton's madness, again, which is given by a French biographer, and which is ably re- futed by Sir David Brewster, may owe much of its piquancy to what may be called the unconscious inventiveness of prejudice. Very possi- bly the stories of the visions of Brutus, Cromwell, and others, have had a like origin. Again, it will be said that even medical men — wishing like others to magnify their office — may have been too ready in spying out the symptoms of insanity. If they are fallible in dealing with the living subject, all of whose physical and mental characteristics are accessible to observation, how much more likely are they to err in diagnosing the minds of the dead by help of a few fragmentary indications only ! I think the force of this objection, too, must be allowed. "When, for ex- ample, a French alienist thinks it worth while to write a book in order to prove that the belief of Socrates in a controlling divinity {to SaifjLoviov) was a symptom of mental disease, a layman may be par- doned for demanding a mode of investigation more in accordance with the proud claims of science to our absolute and unstinted confidence. A well-informed and critical reader of M. Moreau's tables of bio- graphical facts will not fail to challenge more than one statement of his respecting the morbid characteristics of great men, ancient and modern.* Allowing, however, for a margin of error, I do not think any candid mind will fail to see that such a body of facts as remains is sufficient to justify us in drawing a conclusion. If men of the highest intellectual caliber were not more liable to mental and nervous dis- orders than others, no such list out of the short roll of great names could have been obtained. No elaborate calculations are needed, I think, to show that mental malady occurs too often in the history of genius.f One might perhaps try to evade the unpalatable conclusion by say- ing that there is genius and genius ; that it is weakly, one-sided, and bizarre originality which exhibits these unhealthinesses, whereas the larger and more vigorous productiveness of an Aristotle, a Shake- speare, or a Goethe, is free from such blemishes.^ I think, however, * As when he sees in Swift's witty pamphlet on Ireland a distinct presage of oncom- ing insanity. In some cases he is inexact in stating his facts, as when he says that Saint- Simon committed suicide. f The proportion is the more striking, because it is not known that insanity is par- ticularly frequent among the more highly educated class of the community. \ This seems to be the idea of Dr. Oliver Wendell Holmes when he distinguishes between poets of "great sun-kindled constructive imagination" and those who have "a GENIUS AND INSANITY. 459 that our facts will compel us to reject this saving clause. There is no question among competent critics of the splendid quality of genius of Swift, of Carlyle, or of Beethoven. Nor in cases of so-called healthy genius can it be said that nothing abnormal ever shows itself. The above references to Goethe may serve to indicate the liability to ab- normal deviation even in the strongest and seemingly most stable type of genius. As for Shakespeare, the instance commonly referred to by Lamb and others who have come to the defense of genius, it is enough to say that our knowledge of his personality and life is far too meager to justify any conclusion on the point.* And this brings us to another very important consideration. If too much has been made of the alleged positive instances, too much has been made also of the apparent contradictions or exceptions. The record of past greatness is far too scanty for the most plodding stu- dent to find all cases of morbid symptoms which have presented them- selves. We who live in an age when a fierce light beats on the throne of intellect, when the public which genius serves is greedy of every trivial detail of information respecting its behavior in the curtained recess of private life, can hardly understand how our ancestors could have neglected to chronicle and to preserve the words and deeds of the greatest of men. Yet such is the case, and the further we go back the scantier the biographic page. Inasmuch, too, as many of the symptoms of nervous disease in the intellectual heroes themselves or their families would possess no significance to the ordinary lay mind, we may feel confident that in many cases where we have a fairly full record important data are omitted. Another thought naturally occurs to one in this connection. With- out indorsing the ancient proverb that the best men die in their youth, we may find good grounds for conjecturing that many endowed with the gift of genius have passed away before their powers culmi- nated in the production of a great monumental work. The early col- lapse of so many who did attain fame suggests this conclusion. And among such short-lived and unknown recipients of the divine afflatus it seems reasonable to infer that there were a considerable number who succumbed to some of those forms of j)sycho-physical disease which have so often attacked their survivors. It seems, then, to be an irresistible conclusion that the foremost among human intellects have had more than their share of the ills that flesh is heir to. The possession of genius appears in some way to be unfavorable to the maintenance of a robust mental health. And here arises the question how we are to view this connection. Is the certain kind of moonlight genius given them to compensate them for their imperfection of nature," and who are invariably " tinged with melancholy " (" Autocrat of the Break- fast-Table," chap. viii). * Even the little that we know does not all point one way. Against the fine business capacity, and so forth, we have to set the youthful excesses of which rumor speaks. 460 THE POPULAR SCIENCE MONTHLY. presence of the creative faculty to be regarded as itself an abnormal excrescence in the human mind ? Or is it that the possession and fruition of the faculty are apt to be attended with circumstances which are injurious to perfect mental well-being? In order to understand the precise relation between two things, we ought to know all about the nature and causes of each. But this we are very far from knowing in the present case. Science has, no doubt, done much to clear up the ancient mystery of madness. We now know that it has a perfectly natural origin, and we understand a good deal respecting the more conspicuous agencies, psychical and physical, predisposing and exciting, which bring about the malady. Yet so intricate is the subject, so complex and subtile the influences which may conspire to just disturb the mental balance, that in many cases, even with a full knowledge of an individual and his antecedents, the most skillful expert finds himself unable to give a complete and exhaustive explanation of the phenomenon. With respect to genius the case is much worse. We may have a clearer intuition of its organic composition than the ancients ; we may be able better than they to describe in psychological terms the essen- tial qualities of the original and creative mind. But we have hardly advanced a stej) with respect to a knowledge of its genesis and ante- cedents. We do, no doubt, know some little about its family history. Mr. Galton, with his characteristic skill in striking out new paths of experimental research, has brought to light a number of interesting facts with respect to the hereditary transmission of high intellectual endowments. But these researches supply no answer to the supremely interesting question, How does the light of genius happen to flash out in this particular family at this precise moment ? A preparation there may be, as Goethe somewhere hints, in the patient building up by the family of sterling intellectual and moral virtues. But this is hardly the beginning of an explanation. How much the better are we able to comprehend Carlyle's wondrous gift of spiritual clairvoyance for knowing that he came of a thoroughly sound stock, having more than the average, it may be, of Northern shrewdness ? To trace the family characteristics in a great man is one thing, to explain the genius which ennobles and immortalizes these is another.* In the present state of our knowledge, then, genius must be looked upon as the most signal and impressive manifestation of that tendency of Nature to variation and individuation in her organic formations which modern science is compelled to retain among its unexplained facts. Why we have a Shakespeare, a Michael Angelo, a Goethe here * Much the same applies to what M. Taine and others hare said about the larger prepa- ration of the original teacher and the artist by the traditions of the community and the spirit of the age. See, for a careful treatment of the whole question of the antecedents of genius, an article by M. H. Joly, " Psychologie des Grands Ilommes" (III) in the " Re- vue Philosophique," August, 1882. GENIUS AND INSANITY. 461 and now, is a question that can not be answered. Our ignorance of the many hidden threads that make up the inextricable skein of causation forces us to regard each new appearance of the lamp of gen- ius with much of the wonder, if with something less of the supersti- tion, with which the ancients viewed it. This being so, we must be content with a very tentative and pro- visional theory of the relations between genius and mental disease. We can not, for example, follow M. Moreau in his hardy paradox that genius has as its material substratum a semi-morbid state of the brain, a neuropathic constitution which is substantially identical with the "insane temperament" or "insane neurosis."* For, first of all, the facts do not support such a generalization. If the "genial tempera- ment " involved a distinct constitutional disposition to insanity, the number of great men who had actually become insane would certainly be much greater than it is. And, in the second place, this proposition reposes on far too unsubstantial a basis of hypothetical neurology. We know too little of the variations of nerve structure and function to pronounce confidently on the essential identity of the nervous organi- zation in the case of the man of genius and of the insane." f A more modest and possibly more hopeful way of approaching the question appears to offer itself in the consideration of the psychical characteristics of genius. We may inquire into those peculiarities of sensibility and emotion, as well as of intellect, which are discoverable in the typical psychical organization of the great man, and may trace out some of the more important reflex influences of the life of intellect- ual production on his mind and character. What we all recognize as genius displays itself in some large original conception, whether artis- tic, scientific, or practical. And it seems not improbable that by a closer investigation of the conditions and the results of this large con- structive activity of mind we may find a clew to the apparent anomaly that grand intellectual powers are so frequently beset with mental and moral infirmity. These lurking-places of abnormal tendencies will, we may expect, betray themselves more readily in the case of artistic and especially poetic genius, which has, indeed, always been viewed as the most pronounced form, and as the typical representative of creative power. No careful student of genius can fail to see that it has its roots in a nervous organization of exceptional delicacy. Keenness of sensibility, both to physical and mental stimuli, is one of the fundamental attri- butes of the original mind. This preternatural sensitiveness of nerve has been illustrated in the two latest records of poetic genius. Car- * Op. cit., p. 463, seq. \ Dr. Haudsley is more guarded, contenting himself with saying, "It is truly re- markable how much mankind has been indebted for special displays of talent, if not of genius, to individuals who themselves, or whose parents, have sprung from families in which there has been some predisposition to insanity " (" Responsibility in Mental Dis- ease," p. 47). 462 THE POPULAR SCIENCE MONTHLY. lyle's lively impressibility to sounds and other sensuous agents is famil- iar to all.* And of George Eliot it has been well said that " her nerves were servile to every skyey influence." And what a range and intensity of emotion are at once suggested by names like Milton, Dante, Shelley, Heine ! This fineness of the sentient fiber stands in the closest relation to the intellectual side of genius. It is not so much an accompaniment of the creative imagination as its vitalizing principle. The wide and penetrating vision of the poet is the correlative of his quick, delicate, and many-sided sensibility. And the stimulus which ever urges him toward the ideal region, which makes him devote his days to the pur- suit of some ravishing idea, has its origin in his rare, almost superhu- man, capacity of feeling. The modest limits of the real world fail to slake his thirst for the delight of beauty, for the raptures of the sub- lime. Hence the impulse to fashion new worlds of his own. And by such ideal activities the emotional sensibilities which prompted them are deepened and intensified. It is easy to see, from this glance at the fundamental conditions of imaginative creation, that it has one of its main impulses in un- common experiences of suffering. The fine nervous organization, tremulously responsive to every touch, constitutes in itself, in this all too imperfect world of ours, a special dispensation of sorrow. Ex- quisite sensibility seems to be connected with a delicate poise of nervous structure eminently favorable to the experience of jarring and dislocated shock. And it is this preponderance of rude shock over smooth, agreeable stimulation — of a sense of dissonance in things over the joyous consciousness of harmony — which seems to supply one of the most powerful incitants to the life of imagination. Hence the dark streak of melancholy which one so often detects in the early years of the great man. Such an attitude of mind must entail suffering in other ways, As the biography of the man of genius often tells us, he is apt to become aware, at a painfully early date, that his exceptional endow- ments and the ardent consuming impulses which belong to them col- lide with the utilities and purposes of ordinary life. The soul intent on dreaming its secret dream of beauty is unfit for the business which makes up the common working life of plain, prosaic men. The youth to whom the 'embodiment of a noble artistic idea or the discovery of a large, fructifying, moral truth is the one absorbing interest, will be apt to take a shockingly low view of banking, schoolmastering, and the other respectable occupations of ordinary citizens. It follows that the man of genius is, by his very constitution and vocation, to a considerable extent a solitary. He is apt to offend the world into which he was born by refusing to bow the knee to its con- ventional deities. His mood of discontent with things presents itself * Goethe, Schopenhauer, and other great men, were particularly sensitive to sounds. GENIUS AND INSANITY. 463 as a reflection on their contented view. On the other hand, his pe- culiar leanings and aspirations are incomprehensible to them, and stamp him as an alien. "II y a peu de vices," says Chamfort, with a grim irony, " qui empechent un homme d'avoir beaucoup d'amis, autant que peuvent le faire de trop grandes qualites." Hence the profound solitude of so many of the earth's great ones, which even the companionships of the home have not sufficed to fill up. And it must be remembered that the ardent emotions of the man of genius bring their extra need of sympathy. Even the consciousness of in- tellectual dissent from others may become to a deeply sympathetic nature an anguish. " I believe you know " (writes Leopardi to a friend), " but I hope you have not experienced, how thought can crucify and martyrize any one who thinks somewhat differently from others." Such isolation is distinctly unfavorable to mental health. It de- prives a man of wholesome contact with others' experience and ideas, and disposes to abnormal eccentricities of thought. It profoundly affects the emotional nature, breeding melancholy, suspicion of others, misanthropy, and other unwholesome progeny. The " strange inte- rior tomb life " of which Carlyle speaks is a striking example of the influence of this isolation in fostering the minute germs of morbid de- lusion. If now we turn to the process of intellectual origination, we shall find new elements of danger, new forces adverse to the perfect serenity of mental health. If the rich biographical literature of modern times teaches us anything, it is that original production is the severest strain of human faculty, the most violent and exhausting form of cerebral action. The pleasing fiction that the perfectly-shaped artistic product occurs to the creative mind as a kind of happy thought is at once dis- pelled by a little study of great men's recorded experience. All fine original work, it may be safely said, represents severe intellectual labor on the part of the producer, not necessarily at the moment of achievement, but at least in a preparatory collection and partial elabo- ration of material. The rapidity with which Scott threw off his mas- terpieces of fiction is only understood by remembering how he had steeped his imagination for years in the life, the scenery, and the his- tory of his country. It is to be remembered, too, that this swift and seemingly facile mode of creation is by no means an easy play of faculty, akin to the spontaneous sportiveness of witty talk. It involves the full tension of the mental powers, the driving of the cerebral machine at full speed. According to the testimony of more than one man of genius, this fierce activity is fed and sustained by violent emotional excitement.* * Byron, Goethe, Dickens, and others attest to this. Compare what George Eliot says about the way in which the third volume of " Adam Bcde " was produced (" Life," voL ii, p. 155). 464 THE POPULAR SCIENCE MONTHLY. The notion of producing a work of high imaginative power in a state of perfect cold blood is, as Plato long ago pointed out, absurd. Spiritual generation only takes place when the soul burns and throbs as with a fever. At the moment of productive inspiration the whole being is agitated to its depths, and the latent deposits of years of experience come to the surface. This full spring-tide of imagination, this cerebral turmoil and clash of currents, makes the severest demands on the controlling and guiding forces of volition. And it is only when the mind is capable of the highest effort of sustained concen- tration that the process of selecting and organizing can keep pace with the rapid inflow of material. Hence, though the excitement may in certain cases be intensely j>leasurable, it is nearly always fatiguing and wearing. But great artistic works are not always flashed into the world by this swift electric process. Some books that men will not let die have been the result of lengthened toil troubled by many a miserable check and delay. The record of Carlyle's experience sufficiently illustrates the truth that there is no necessary relation between rapidity of in- vention and execution and artistic value of result,* Much depends on the passing mood, more still on the temperament of the individual artist. There are others besides Carlyle to whom spiritual parturition has been largely an experience of suffering, the pangs being but rarely submerged in the large, joyous consciousness that a new idea is born into the world. And when this is so there is another kind of strain on the mental machine. The struggle with intellectual obstacle, the fierce passionate resolve to come iris Heine which every student ex- periences in a humble way, becomes something for the spectator to tremble at. Is it surprising that such states of mental stress and storm should afterward leave the subject exhausted and prostrate ? The wild excitement of production is apt to dull the sense still further to the prosaic enjoyments with which ordinary mortals have to content them- selves. More than this, the long and intense preoccupation with the things of the imagination is apt to induce a certain lethargy and stupor of the senses, in which the sharp outlines of reality are effaced in a misty, dream-like phantasmagoria. The reader of Carlyle's " Mem- oirs " need not be reminded how plainly all this appears in his expe- rience. Even the warm and gladdening ray of dawning prosperity failed to cheer him in these hours of spiritual collapse. And he ex- claims in one place that there is no other pleasure and possession for him but that of feeling himself working and alive, f * M. Joly illustrates the same fact by the experience of Voltaire, " Revue Philoso- phiquc," November, 1882, pp. 496, 497. f "Thomas Carlyle," vol. ii, p. 129. Probably one reason why painters so rarely show morbid mental traits is that in their case the function of the senses can never be so completely overborne by the weight of imagination. GENIUS AND INSANITY. 465 In addition to these adverse forces, which have their origin in the common conditions of the life of genius, there are others which, though less constant, present themselves very frequently in co-operation with the first. It has often been remarked that the man of decided origi- nality of thought, being as it were one born out of due time, has to bear the strain of production for a while uncheered by the smile of recognition. And when there is great originality, not only in the ideas, but in the form of expression, such recognition may come too slowly to be of any remunerative value. Neglect or ridicule is the form of greeting which the world has often given to the propounder of a new truth ; and where, as frequently happens, the want of instant recognition means the pressure of poverty, which chafes with unusual severity the delicate fibers of sensitive men, we have a new and con- siderable force added to the agencies which threaten to undermine the not too stable edifice of the great man's mental and moral con- stitution. Johnson, Lessing, Burns, Leopardi, and many another name, will here occur to those familiar with the lives of modern men of letters. In view of this combination of threatening agencies, one begins to understand the many eloquent things which have been said about the fatality of great gifts. Thus one finds a meaning in the definition of poetic genius given by Lamartine when speaking of Byron — " a vibra- tion of the human fiber as strong as the heart of man can bear without breaking." It is not meant here that even when all these destructive elements are present a distinctly pathological condition of mind must neces- sai'ily ensue. Their effect may be fully counteracted by other and resisting agencies. Of these the two most important are bodily energy and health on the one hand, and strength of will or character on the other. Where these are both found in a high degree of perfection, as in Goethe, we have a splendid example of healthy genius. On the other hand, if either, and still more if both of these are wanting, we have a state of things which is exceedingly likely to develop a dis- tinctly pathological state of mind.* How, it may be asked, does it commonly fare with the world's intellectual heroes with respect to these means of defense ? As to the physical defense, it is known that a number of great men have had a physique fairly adequate to the severe demands made on the nervous organization. They were men of powerful frame, strong muscles, and good digestion. But such robustness of bodily health seems by no means the common rule. The number of puny and ill-formed men who have achieved marvelous things in intellectual production is a fact which has often been remarked on. So common an accompani- ment of great intellectual exertion is defective digestion, that an in- * That is, quite apart from any inherited physical predisposition to nervous disease. vol. xxvii. — 30 466 THE POPULAR SCIENCE MONTHLY. genious writer has tried to show that the maladies of genius have their main source in dyspepsia.* No Englishman, in thinking of this question, can fail to recollect that the three of his countrywomen who have given most distinct proof of creative power — Charlotte Bronte, Mrs. Browning, and George Eliot — were hampered with a physical frame pitiably unequal to support the cerebral superstructure.! Coming now to the moral defense, the thought at once suggests itself that, according to the testimony of more than one writer, genius consists in preternatural force of will more than in anything else. It is, we are told, only the man with an infinite capacity to take pains who is truly great. The prolonged, intense concentration of mind which precedes the final achievement is a severe exertion and striking manifestation of will. At the same time, a moment's thought will show us that this pa- tient mental incubation is no proof of the higher qualities of will and moral character. J The appropriateness of the old way of speaking of creative inspiration as a possession is seen in the fact that the will has little to do with bringing on the condition. " The author," said Lord Beaconsfield, on one occasion, " is a being with a predisposition which with him is irresistible, a bent which he can not in any way avoid, whether it drags him to the abstruse researches of erudition, or induces him to mount into the feverish and turbulent atmosphere of imagina- tion." This sense of a quasi-exterior pressure and compulsion is attested by more than one child of genius. In some cases, more par- ticularly, perhaps, among " tone-poets," we find this mastery of the individual mind by the creative impulse assuming the striking form of a sudden abstraction of the thoughts from the surroundings of the moment. And, throughout the whole of the creative process, the will, though, as we have seen, exercised in a peculiarly severe effort, is not exercised fully and in its highest form. There is no deliberate choice of activity here. The man does not feel free to stop or to go on. On the contrary, the will is in this case pressed into the service of the par- ticular emotion that strives for utterance, the particular artistic impulse that is irresistibly bent on self-realization. There is nothing here of the higher moral effort of will, in choosing what wre are not at the * R. R. Madden, "On the Infirmities of Genius." f Schopenhauer, in the passages of his work already referred to, discusses in a cu- rious and characteristic way the physical basis of genius. Moreau quotes approvingly the remark of Lccanus, that men of the finest genius were " of a feeble constitution and often infirm." On the other hand, Mr. Galton, in his " Hereditary Genius," contends that the heroes of history are at least up to the average of men in physical strength. It is to be remarked, however, that the reference to university statistics is apt to mislead here. Senior wranglers can hardly be taken as representative of creative power. \ It is evident that only speculative, as distinguished from practical genius, is here referred to. The man of great constructive powers in affairs — the statesman, general, and so forth — requires will in the higher and fuller sense. And it has been remarked that these organizing intellects rarely exhibit pathological symptoms. GENIUS AND INSANITY. 467 moment inclined to, and resisting the seductive force of extraneous excitants.* These fragmentary remarks may help us to understand the facts of the case. A certain proportion of great thinkers and artists have shown moral as well as intellectual heroism. Men who were able to take the destruction of a MS. representing long and wearisome research, as Newton and Carlyle took it, must have had something of the stuff of which the stoutest character is woven. The patient upbearing against hardship of men like Johnson and Lessing is what gives the moral relish to the biography of men of letters. More than one intel- lectual leader, too, has shown the rare quality of practical wisdom. Goethe's calm strength of will, displaying itself in a careful ordering of the daily life, is matter of common knowledge. Beethoven man- aged just to keep himself right by resolute bodily exercise. In George Eliot an exceptional feeling of moral responsibility sufficed for a nice economizing of the fitful supply of physical energy. At the same time, our slight study of the ways of genius has fa- miliarized us with illustrations of striking moral weaknesses. We have seen a meaning in Rochefoucauld's paradox, that " il n'appartient qu'aux grands hommes d'avoir de grands defauts." The large draught of mental energy into the channels of imaginative production is apt to leave the will ill-provided in working out the multifarious tasks of a temperate and virtuous life. Our conclusion is, that the possession of genius carries with it special liabilities to the action of the disintegrating forces which envi- ron us all. It involves a state of delicate equipoise, of unstable equi- librium, in the psycho-physical organization. Paradoxical as it may seem, one may venture to affirm that great original power of mind is incompatible with nice adjustment to surroundings, and so with per- fect well-being. And here it is that we see the real qualitative dif- ference between genius and talent. This last means superior endow- ment in respect of the common practical intelligence which all men understand and appraise. The man of talent follows the current modes of thought, keeps his eye steadily fixed on the popular eye, produces the kind of thing wThich hits the taste of the moment, and is never guilty of the folly of abandoning himself to the intoxicating excitement of production. To the original inventor of ideas and molder of new forms of art this intoxication is, as we have seen, everything. He is under a kind of divine behest to make and fashion something new and great, and at the moment of compliance recks little of the practical outcome to himself. And such recklessness is clearly only one form of imprudence, and so of mal-adaptation. * This fact of tbe absence of choice, and the ordinary co-operation of the personal will in artistic production, is illustrated further in the rapidity with which the mind casts off and ignores its offspring. " Est-ce bien moi qui ai fait cela ? " asked Voltaire once, on seeing one of his dramas acted. George Eliot attests to this strange unmaternal feel- ing toward her literary .children. 468 THE POPULAR SCIENCE MONTHLY. But, if improvident, he is improvident in a high cause. Emerson and others have taught us the uses of the great man. The teacher of a new truth, the discoverer of a higher and worthier form of artistic expression, is one in advance of his age, who, by his giant exertions, enables the community, and even the whole race, to reach forward to a further point in the line of intellectual evolution. He is a scout who rides out well in advance of the intellectual army, and who by this very advance and isolation from the main body is exposed to special perils. Thus genius, like philanthropy or conscious self-sacrifice for others, is a mode of variation of human nature which, though unfa- vorable to the conservation of the individual, aids in the evolution of the species. If this be a sound view of the nature and social function of the man of genius, it may teach more than one practical lesson. Does it not, for example, suggest that there is room just now for more con- sideration in dealing with the infirmities of great men ? There is no need of exonerating intellectual giants from the graver human respon- sibilities. We do well to remember that genius has its own special responsibilities, that noblesse oblige here too. At the same time we shall do well also to keep in mind that the life of intellectual creation has its own peculiar besetments, and that in the very task of fulfilling his high and eminently humane mission, and giving the world of his mind's best, the great man may become unequal to the smaller forti- tudes of every-day life. To judge of the degree of blameworthiness of faults of temper is a nice operation, which may even transcend the ability of a clever and practiced critic. Perhaps the temper most ap- propriate to the contemplation of genius, and most conducive to fair- ness of moral judgment, is one in which reverence is softened by per- sonal gratitude, and this last made more completely human by a touch of regretful pity. — Nineteenth Century. AN EXPERIMENT IN PRIMARY EDUCATION. By Dr. MARY PUTNAM-JACOBI. I. IN modern times education has been recognized to be something more than an elegant luxury, designed exclusively for the benefit of the " upper classes." It is a force, and a potent and indisputable means, not only for the training but for the evocation of forces. It is able, not only to convey information, but to increase power. It is not simply a social convention, but a real means for attaining real ends. The final ends of education are efficiency and repose. The educated person is he who knows how to get what he wants, and how to enjoy it when he has got it. AN EXPERIMENT IN PRIMARY EDUCATION 469 When a "higher education " is demanded, for any class of persons — as women — it means that it has hecome desirable to train their fac- ulties for more difficult work than that traditionally assigned to them, and also that it is desirable to enable them to get more enjoyment out of any work that they do. The necessary correlative of the possession of powers is the opportunity for their exercise. The existence of a larger class of effectively educated women must increase their demand for a larger share in that part of the world's work which requires trained intelligence. Of this, literature and other art is one and only one portion. The work of the professions, of the upper regions of in- dustry, commerce, and finance, the work of scientific and of political life, is the work appropriate to the intelligences which have proved themselves equal to a course of training at once complex and severe. A person destined to receive a superior education is expected to de- velop more vigorous mental force, to have a larger mental horizon, to handle moi'e complex masses of ideas, than another. From the be- ginning, therefore, he must not merely receive useful information, but be habituated to perform difficult mental operations, for only in this way can the sum of mental power be increased. The order, ar- rangement, and sequence of the ideas he acquires must be as carefully planned as is the selection of the ideas themselves, because upon this order and internal proportion his mental horizon depends. He must be trained in feats of sustained attention, and in the collocation and association of elementary ideas into complex combinations. Since ideas are abstractions from sense-perceptions, he must be exercised in the acquisition of accurate, rapid, fai*-reaching, and delicate sense perceptions, in their memorization, and in the representative imagina- tion which may recall them at will, and be able to abstract from them, more or less remotely, ideas. Habits of rich association of ideas must be formed, and of pleasure in their contemplation. And very early must be offered to the child problems to be solved, either by purely mental exertion, or by that combined with manual labor. And all this care must be taken for girls as well as for boys, so soon as it is seriously agreed that girls may be admitted to a superior as well as to a primary education. The first intellectual faculties to be trained are perception and memory. The subjects of the child's first studies should therefore be selected, not on account of their ultimate utility, but on account of their influence upon the development of these faculties. What sense is there, then, in beginning education with instruction in the arts of reading and writing ? If literature were the main business of life, or if, as was at one time supposed, education meant nothing else but ac- quaintance with literature, there would be some logic in the extraor- dinary prominence habitually assigned in education to the study of modes of literary expression. But, from the modern stand-point, that education means such an unfolding of the faculties as shall put the 470 THE POPULAR SCIENCE MONTHLY. mind into the widest and most effective relation with the entire world of things — spiritual and material — there is an exquisite absurdity in the time-honored method. To study words before things tends to im- press the mind with a fatal belief in their superior importance. To study expression before subjects of thought have been accumulated, is to cultivate the habit, always prevalent in civilized life, of talking fluently without having anything to say. To direct attention to sets of arbitrary signs before attention has been trained by contemplation of real objects, teaches the mind to place conventional and contingent facts on the same level with necessary truths. We thus weaken in advance the power of belief in necessity and reality. Without such power the mind becomes inevitably the prey to a skepticism generated much less by contradictions in the outside world, than by the weakness of its internal organism. What other result should logically be pro- duced, when, to the opening mind, as it turns eagerly to the wonderful world in which it awakens and finds itself, we offer for contemplation, exercise, and earliest sustenance, the alphabet, the abstruse structure of words to be spelled, the grammar of sentences to be construed, the complex gymnastics of copies to be written ? When to the reading, writing, spelling, grammar, and composition in English, we add that of similar exercises in two or three other languages, we evidently de- scribe the education, first, of the children in our public schools, then of those of the so-called " upper classes " ; and show that all is a pro- longed study of words. Words are fossils, which, according to the understanding had of them, are a heap of meaningless stones, or the incarnation of a by- gone life. When the child has once learned to handle present exist- ences, he will be prepared to understand the reflections of a past life in language. When he has had some experience in framing complex abstractions, he can then appreciate the complex abstractions of speech. But, until then, language should not be to him an object of thought, but only an organ of thought. It is not to be driven into him, but only out of him, through the urgent consciousness that something must be said. The inflections, intonations, and emphasis of speech, uttered or written — and which include grammar, rhetoric, punctua- tion, style — must arise spontaneously, as natural clothing of the idea, which insists upon making itself understood. An idea which is once sufficiently vivid in the child's mind can hardly fail to " climb to a form in the grass and flowers " of picturesque baby-speech. On this principle it might be useful to precede study of either spoken or written language by study of gestures and signs. At all events, in my own experiment, the child was taught algebraic signs as a means of concisely expressing certain relations, long before any attempt was made to learn how to write. Thus the important, funda- mental idea was early conveyed to her mind that all arts of expression were subordinate in importance to the subject expressed. Deliberate AN EXPERIMENT IN PRIMARY EDUCATION. 471 study of the arts of expression, which is equivalent to the study of literature, rhetoric, and style, was reserved until after many years of study of things should have accumulated impressions and ideas which spontaneously sought an outlet. Further, the child was taught to draw in simple combinations of lines for many months before attempt- ing to write. When this difficult and complex muscular exercise was approached, she began it with unusual ease, and in a few weeks, at the age of six, already commanded a firm and legible handwriting. Fur- ther, and for the same purpose, no set copy-book was used from which meaningless sentences could be imitated ; but the child proceeded at once to utilize the art of writing in precisely the same way that hu- manity has done in passing from barbarism with spoken traditions, to civilization with a recorded history. She recorded at first with printed, afterward with script characters, the history of a group of hyacinths, whose development she watched from birth to death. The writing, though compelled to be carefully done, was recognized as no end in itself, but as a means to preserve a connected history of a series of interesting events, otherwise liable to lapse into oblivion. The art was thus approached as all arts should be, from the stand-point of its real genesis, and tended to place itself in the same relative position in the child's mind that it had occupied in the real history of the world. Study of the pathological conditions of writer's cramp, and of the numerous brain-lesions which have so marvelously dissected the fac- ulty of comprehending verbal and written signs, has revealed a hith- erto unsuspected complexity in the muscular movements involved in writing, and of the mental processes necessary to language.* The discovery has not yet modified the glaring crudity of the educational methods which persist in beginning mental training with a forced drill in these complex processes and gymnastics. Not speech abstractions, the highest conquest of the mind, but the development of the visual conceptions, which are its earliest sponta- neous achievement, should be the first object of systematic training. Forms and colors are the elements of all visual impressions ; and these are, moreover, susceptible of a scientific classification which can, from the beginning, be rendered appreciable to the child. It is upon forms and colors, therefore, that both perception and memory must first be exercised. The visual impression should be amplified up to the point at which it is able to fix itself on the mind by its own momentum ; therefore, without conscious effort. When the mind has accumulated a stock of reminiscences which can not be forgotten, it will, by so much, have enriched its structure and enlarged its furniture. It is then prepared for voluntary efforts at recollection. The amplification of the impression is effected in two ways : 1. The impression may be associated with an action on the part of the child, * See Kussmaul, " Stoerungen der Sprache " ; also, Lichtheim on " Aphasia " (" Brain," January, 1885). The literature on these two subjects is already immense. 472 THE POPULAR SCIENCE MONTHLY. as when he arranges building-blocks into definite forms. 2. The outlines of the object itself may be magnified, and at the same time roughened, by being copied with sticks, as may be done in the first attempts at map-drawing. The copy substitutes a schematic outline for the real one, but by the very fact blends a mental conception with the simple visual image. This necessity for amplification is very im- portant, and, as it seems to me, very often overlooked. It is strictly in accordance with the physiological law in neuro-dynamics, that a stimulating impression must vary in intensity inversely to the suscepti- bility of the nerve-element to be impressed. The more developed and vigorous the mind, the slighter the object that is perceived and re- membered ; and, as Mr. Froude remarks, men of genius always have tenacious memories. Conversely, the relatively feeble mind of the young child requires a large object to awaken its prehensile faculties. If the memory of children for what has once impressed them is often remarkable, it is because the infantile period of mental development bears much analogy with the character of genius. It seems to me that for several years no abstract statements should be made to a child, except such as may be, at least schematically, rep- resented by tangible objects, and at every new point of even advanced studies recurrence to such schemas may be usefully made. Perception and memory should be indissolubly associated. There are two prevalent errors of method wThich I have noticed : to expect a child to remember what it has never perceived ; and to allow it to perceive without any systematic representation of the object in memory. In the earliest training, contemplation of an object is insuf- ficient to fix its outlines on the mind : it must be handled as well as seen. In my own experiment with a child of four, Froebel's building- blocks were used to construct definite models ; but these, once framed, were repeated from memory. Sometimes the details of an exciting story, as that of " Blue-Beard," were associated with the different de- tails of the model, so that these were more vividly remembered. By building in succession the different rooms in which the various acts of the tragedy were supposed to have occurred, the child learned, on the one hand, mathematical outlines ; on the other hand, to remem- ber history by, in a degree, acting history herself. The principle of this method is applicable to much more advanced studies. President Hill, in his eloquent little book on the " True Order of Studies," emphatically insists on the necessity for a selection of studies which differ widely from the conventional programme. " We awake to consciousness," he observes, "through the fact of motion which re- veals to us an outer world, and a universe of space and time in which that world of matter moves. These space and time relations are the earliest objects of distinctly conscious intellection ; the first objects concerning which our knowledge takes a scientific form. This was true of the race, and it is true of the individual. Before the child has AN EXPERIMENT IN PRIMARY EDUCATION. 473 a clearly intellectual life on any other subjects, it attains a very defi- nite power to distinguish the square, the circle, the oval, the spiral ; and also to recognize the rhythm of verse and music. Out of space and time arise through the suggestions of the material world three princi- pal sciences : geometry, arithmetic, algebra. In considering space we are led to imitate the act of the Divine Intellect, which has geome- trized from eternity. Geometry is the earliest and simplest of all pos- sible sciences." The writer proceeds to point out that " the earliest abstraction from the idea of form is that of number, and out of this idea is evolved the earliest of the truly abstract sciences, namely, arith- metic. But because this science is based upon an abstraction, and not upon a direct perception, it should be made to follow, and not, as is usually the case, precede geometry." Again, " the earliest suggestions of motion reveal to us time as well as space. But space is external to the mind ; time enters into our spiritual consciousness, and measures our flow of thought." To this might be added the anatomical consideration that the for- mation of space conceptions is the function of the cerebrum, from the impressions furnished by the optic nerve ; while the conceptions of time are elaborated in the cerebellum from the experience in succes- sions of events furnished by the auditory nerve. Space conceptions are objective, static ; time conceptions, from the beginning subjective, are at first successive, then become progressive, finally causal, dynamic — when the conception of cause arises from consideration of the sum of antecedent events. Thus this second series of conceptions soon im- pinges upon moral considerations ; the first remains within the sphere of perceptive intelligence. To space, or optic nerve conceptions, be- longs symmetry ; to time, or auditory nerve conceptions, belong har- mony and rhythm. These ultimate ramifications of the primary psychic phenomenon must be held in mind at the moment of beginning to systematize the visual and auditory perceptions which lie at their basis. All object-teaching may be made useful as a means of training to independent observation. But the study of ordinary, i. e., of complex objects, is necessarily empirical, whereas geometric forms can be at once submitted to scientific generalizations, can therefore at once initi- ate the child into scientific method. Dr. Hill recommends the study of geometry to be begun at the age of eight. The child upon which my own experiment was performed began the study of geometric ele- ments before she was four. Some details of her education may per- haps be quoted as the best way of illustrating certain abstract princi- ples. At the age of four and a half she had learned the following elements : straight, curved, slanting, and half-slanting lines, also to distinguish perpendicular and horizontal lines, and to draw either straight or curved lines parallel to each other. She was well acquainted with all forms of the triangle, equilateral, isosceles, right angle, and 474 THE POPULAR SCIENCE MONTHLY. scalene. She knew a rectangle and a square, and the relations to each of the slanting and half-slanting line. She knew also, and was espe- cially fond of, the trapezium, ti-apezoid, the pentagon, hexagon, etc., the circle and semicircle ; and, in solid figures, knew the cube and its apparent relations to the square. She did not merely know the names of these things, but to her eye the whole perceptible universe arranged itself spontaneously into these fundamental forms ; for she was inces- santly disentangling them from the complex appearances of surround- ing objects. Thus a horse-railroad interested her as an illustration of parallel straight lines which never met, the marks of carriage- wheels as parallel curved lines, the marks of horseshoes, as " dear little curves." She learned that the curved line was the line of living things, and that straight lines belonged exclusively to artificial objects. At dinner she divided her cake into squares or cubes, and made penta- gons and octagons with the knives and forks. She learned that by increasing the number of sides a plane figure gradually progressed from a triangle to a circle ; and thus, on first seeing a cylinder, at once comjtared it to a circle, because " it had ever and ever so many sides," and not to a prism with which the superficial resemblance might be supposed to be more striking. The habit of looking for the forms of things led the child to the spontaneous observation of the alphabet, which she taught herself by incessantly copying the letters until she was familiar with them.* It was at this time that her education devolved upon me, and I began to effect the transition from a simple descriptive study of geometric forms toward some conception of their necessary relations. At first the purely descriptive study of geometric forms was continued, and, for several months and by the help of wooden models, extended from plane to solid figures. Later, when she was five and a half, some neces- sary relations were taught. Thus the child learned that three was the smallest number of straight lines which could include a space, by build- ing with colored sticks an imaginary fence around a field in which a goat was to be inclosed. It was obvious that, when only two sides of the fence were completed, the goat would be able to run out and wreak all the destruction in the garden which might be anticipated from a reckless and unrestrained goat. An indissoluble association of ideas was thus established between a geometric necessity and the logic of events. The second axiom taught was the equality of any two objects which were demonstrably equal to the same third. This was learned when the child was five years old ; and illustrated in the first place by its applicability to the solution of pi'oblems otherwise insoluble. Thus, if it became necessary to compare the height of two girls, one of whom lived in Syracuse and the other in Boston, but unable to visit * This first year of the child's education was carried on in the Kindergarten of Mrs. Walton. AN EXPERIMENT IN PRIMARY EDUCATION 475 each other, a common measure was suggested in the person of a third girl living in New York, of more peripatetic habits, and able to travel from one place to another. By the same device the lesser difficulty was overcome, of comparing the length of a floor and the ceiling of a room through the medium of the wall. Ultimately the problem was illustrated by the less conspicuous mechanisms of colored sticks, and then the first algebraic signs of equality and inequality were taught, thus preceding all knowledge of writing. When the idea had been thus copiously illustrated and perfectly grasped, the verbal axiom (" things equal to the same things," etc.) was, by exception, given, and learned with ease. This was proved by the child's remark on one occasion of applying the axiom, " I knew what I was thereforeing." In a similar way were taught some other axioms — thus, that equals being added to equals the wholes are equal, and that the whole is equal to the sum of its parts. The last axiom was illustrated graphi- cally by observation of a large complex fungus which the child hap- pened to pick up during a walk. Each part was apparently inde- pendent, yet so inseparable from the whole in which it inhered, and the whole was so obviously composed of these aggregated segments, that the axiom in question seemed to the child simply descriptive of the object. Thus the mind was early initiated into the recognition of necessary truths, however few, lest otherwise it should never acquire that sense of reality and necessity which is essential to all forcible mental and moral action. At the beginning of the year, the child being four and a half, the study of elementary colors was added to that of form. It was begun logically with observation of the rainbow. The child was led to notice and distinguish its colors in their regular order, and subsequently to reproduce this order exactly by means of colored sticks. As this was a fundamental observation among those furnished by the universe of things, it was constantly allowed to recur in different combinations in the same way as the original theme of a musical symphony. Thus at first the coloi-ed sticks were laid parallel to each other in a simple package. Subsequently the study of form and color was combined by using the same colored sticks to construct angular geometric fig- ures from the triangle to the decagon. Each figure consisted of seven of different sizes and colors, placed concentrically to each other, in the rainbow order. After several months a third complication was in- troduced, by imagining that each color represented a lineal bed of flowers, the flowers having been previously gathered by the child and their colors compared. At this time solid figures would be placed in the center of the innermost plane figure outlined by the sticks, thus bringing out clearly the relations of the sides of such solids to certain planes. Thus a cube would stand in a square, a tetrahedron or pyra- mid in the center of a triangle. This last case offered the occasion 476 THE POPULAR SCIENCE MONTHLY. for a somewhat wicle reach of fancy : for pictures were shown ex- hibiting pyramids in the Egyptian Desert, to imitate which the table was strewed with sand. Then the different triangles were outlined with sticks, representing successive beds of flowers breaking the desolation of the desert — thus, roses and pinks, then marigolds, then yellow snap-dragons, jonquils, and laburnums, then a bed of green leaves, another of periwinkles and blue bells, a sixth of hyacinths and a seventh of violets. Thus the entire exercise embraced conceptions of form, and of the relations of plane to 6olid geometric figures, con- ceptions of color, discovery of the origin of these in a grand cosmic phenomenon, utilization of colors as one means of classification in a new science, that of botany, impressions of beauty from the actual color combinations, and from reference, partly actual, partly from memory, to the lovely flowers suggested ; finally, a large imagination of a distant land more or less distinctly suggested by the picture. The exercise was thus both orderly and complex ; it required a pro- longed effort of sustained attention, and implied the association of quite a number of different ideas into a single massive conception. Finally, none of these ideas were represented by a verbal formula, but each as the scarcely removed abstraction from a tangible object, that the child could freely handle. The exercise was thus a typical illus- tration of the methods which I have defined as suited to develop a higher order of intellectual capacity. The second step in the study of cosmic phenomena, which had been begun by observation of the rainbow, consisted in study of the points of the compass. The child was first taught to construct, from Kindergarten tablets, figures which might serve to indicate the points of the compass ; afterward she was obliged to recognize these points out-of-doors by reference to the rising and setting sun. Every morn- ing she ascertained the direction of the winds and wraves. She was then taught the points on a real compass, and how to direct her coun- try walks by means of this instrument. This was her first initiation into the use of instruments of precision. It wTas gradually extended during the year by means of practical experiments with the mathe- matical compass, ruler, spirit-level, pulley, wedge, and balance. The use of the last instrument, together with that of measures, greatly simplified and abridged the labor ordinarily devoted in arithmetic to learning about weights and measures. The child was taught the met- ric system first, because it was logical, because it assimilated readily with American decimal currency, and because the mutual interconver- sion of weight and capacity practically demonstrated — e. g., by show- ing that a cubic centimetre of water weighed a gramme — prepared the way for the great idea, to come later, of scientific correlations. The English weights and measures were learned afterward, as historical accidents, not logical, but of some practical convenience, as purely con- tingent knowledge to be learned practically as the occasion presented AN EXPERIMENT IN PRIMARY EDUCATION. 477 itself. She was sent to the grocer's to buy a bushel of apples, com- pared quarts, pecks, etc., together, and was never troubled with the senseless memorization of tables. After knowledge of the rainbow and the points of the compass, the third cosmic notion acquired was that of perspective. This was first learned by watching ships passing over the water near which the child was playing, and observing their diminution of size as the distance in- creased. This observation made a profound impression upon the child ; it was, perhaps, the first time that she learned that appearances do not always correspond to the reality of things, and that simple perceptions must be constantly controlled by an effort of the reasoning intellect. A year later, thus, when the child was five years old, the subject of perspective was reviewed in a different connection. She tried to draw a cube, and was shown the device by which a slanting line is made to represent a retreat from the foreground to a distance. This new dis- covery proved as exciting as the first had been, and it was speedily tested on all the pictures hanging in the room. On the first occasion, perspective had appeared like a great and astonishing fact of the ex- ternal universe ; on the second, like an immense achievement of the human intellect, which had thus contrived to accomplish the appar- ently impossible — namely, the representation of solid objects on a flat surface. The lifting of such large horizons makes epochs in the history of the intellect ! The study was not confined to the form or line, but ex- tended to observation of the effect of li^ht and shade — the darkness of a receding surface, the brightness of the nearest point of a spherical sur- face, etc. Then the child reproduced these effects in her own drawing. At this time the child began the study of geographical maps, as another method of emphasizing space conceptions. For so young a child the dissecting map was much simpler than would have been the attempt to make actual surveys of familiar localities, as is sometimes recommended. These were deferred till a little later. By the aid of the dissecting map, the child learned the outline of each of the United States, and their exact relations to each other, while still quite unable to read the names printed upon the models. In putting the map to- gether, the compass was again brought into requisition, and the table on which the map was constructed turned until it faced the real north. The relative situation of places was always learned by reference to the compass, and not by arbitrary signs. With so young a child it was impossible to associate much real in- formation with these unknown states whose geometrical outlines she studied ; therefore, every facility was offered to establish associations of fantasy, either with the shape of the pieces or with the names, as- sociation which the child usually discovered for herself. Thus, she de- scribed Virginia as a kneeling camel ; Texas, for some reason which I could not appreciate, as a man leaning on his pipe ; Maine, as a dog's head ; Tennessee, as a boy's sled, etc. 478 THE POPULAR SCIENCE MONTHLY. The study of the one dissecting map was pursued uninterruptedly for six months. In a few weeks the child had learned to identify and name each piece, either on her model or on other maps, and could put each in its place. Before she left the map she was able to bound any State with the models, or verbally ; also to make strips of successive States, beginning at any point and running in any direction. With the entrance upon her second year, at the age of five and a half, the child began the study of maps from " Cornell's Geography." But in a very little while these were exchanged for a large relief - globe. From the time the child began the study of this globe it became dif- ficult for me to understand how any other method could ever be em- ployed. The picturesque effect of the distinctly outlined continents, visible at a considerable distance, separated by vast tracts of desolate ocean, in which, as the child remarked, " one could easily drown," the mutual relations of parts whose perception need never be disturbed, as is incessantly done when the pupil passes from map to map — all these effects and impressions can be obtained from nothing else but from a globe of adequate size and in relief. The child, when just six, began to draw maps from this globe. On a single very large piece of paper would be represented whatever outlines were discoverable at the maximum distance and at a certain aspect of the globe. The lat- ter was then revolved somewhat, the child remaining at the same dis- tance, and a new map outlined as before, and so on until the entire globe had been, in the major outlines, copied by the child. It was re- served for months of future study to fill in the details in proportion to their successive natural, not political, importance. Four different spheres of thought were prepared for by this study. First, and most obviously, the foundations were laid for all knowledge of physical geography. This foundation was laid in vivid sense im- pressions, and unalloyed with the singular mess of political, historical, and commercial details, with which even the best geographical text- books for children are filled, and which are quite irrelevant to the main issue. When the child could with her finger trace the water- courses all around the world, she received a large fundamental impres- sion not easily forgotten. Incidentally in this tracing she learned the value of canals at the Isthmuses of Suez and Panama. Secondly, a solid foundation was laid for history. The first map drawn was of Africa, on account of its simplicity of outline ; but this involved the basin of the Mediterranean. The second map, passing eastward, took in the strongly accentuated outlines surrounding the Indian Ocean, and indi- cated the Himalaya and the high table-lands of Northern India. In the future it was intended, with these same outlines under the eye, and the picture of them deeply graven on the brain, to indicate the descent of Aryan ancestors from these table-lands toward the Mediterranean basin — the germinal spot of our historical world ; thence the further spread westward to the new hemisphere. The conception of an histori- ON LEAVES. 479 cal germinal spot was again prepared for in advance, by showing the child the cicatricule of a hen's egg, lying like the Mediterranean basin, on a globe. Thirdly, study of the systematized topography of the globe constituted the best initiation into the study of all topographi- cal relations, including those involved in animal anatomy, and there- fore this consideration was not among the least important. Fourthly, an important elementary philosophical training was obtained, as the child learned to analyze into their details the largest pictures offered by the globe, and to arrange these details into orders of successive degrees of generalization. Great care was taken that all pictures or outlines of the same magnitude, and hence visible at the same dis- tance, should be studied at the same time, and not associated with less conspicuous details that required more minute attention. This rule of following successive degrees of generalization in geographical analysis is most imperfectly observed in text-books. It imposes itself in study of the relief -globe. \_To be continued.] -■♦«» ON LEA YES. By Sir JOHN LUBBOCK. II. WE have hitherto been considering, for the most part, deciduous trees. It is generally supposed that in autumn the leaves drop off because they die. My impression is that most persons would be very much surprised to hear that this is not altogether the case. In fact, however, the separation is a vital process, and, if a bough is killed, the leaves are not thrown off, but remain attached to it. Indeed, the dead leaves not only remain in situ, but they are still firmly attached. Being dead and withered, they give the impression that the least shock would detach them ; on the contrary, however, they will often bear a weight of as much as two pounds without coming off. In evergreen species the conditions are in many respects different. When we have an early fall of snow in autumn, the trees which still retain their leaves are often very much broken down. Hence, perhaps, the comparative paucity of evergreens in temperate regions, and the tendency of evergreens to have smooth and glossy leaves, such as those of the holly, box, and evergreen-oak. Hairy leaves especially retain the snow, on which more and more accumulates. Again, evergreen leaves sometimes remain on the tree for several years ; for instance, in the Scotch pine three or four years, the spruce and silver-fir six or even seven, the yew eight, A. pinsapo sixteen or seventeen, araucaria and others even longer. It is true that during 48o THE POPULAR SCIENCE MONTHLY. the later years they gradually dry and wither ; still, under these cir- cumstances they naturally require special protection. They are, as a general rule, tough, and even leathery. In many species, again, as is the case with our holly, they are spinose. This serves as a protection from browsing animals ; and in this way we can, I think, explain the curious fact that, while young hollies have spiny leaves, those of older trees, which are out of the reach of browsing animals, tend to become quite unarmed. In confirmation of this I may also adduce the fact that while in the evergreen-oak the leaves on well-grown trees are entire and smooth- edged like those of the laurel, specimens which are cropped and kept low form scrubby brushes with hard prickly leaves.* Mr. Grindon, in his " Echoes on Plant and Flower Life " (p. 30), says that "the occurrence of prickles only here and there among plants shows them to be unconnected with any general and ruling require- ment of vegetation. We can only fall back upon the principle laid down at the outset, that they are illustrations of the unity of design in Nature, leading us away from the earth to Him who is ' the end of problems and the font of certainties.' " Surely, however, it is obvious that the existence of spines and prickles serves as a protection. Another point of much importance in the economy of leaves is the presence or absence of hairs. I have already observed that most ever- greens are glossy and smooth, and have suggested that this may be an advantage, as tending to prevent the adherence of snow, which might otherwise accumulate and break them down. The hairs which occur on so many leaves are of several different types. Thus, leaves are called silky when clothed with long, even, shining hairs (silver- weed) ; pubescent or downy, when they are clothed with soft, short hairs (strawberry) ; pilose, when the hairs are long and scattered (herb-robert) ; villous, when the hairs are rather long, soft, white, and close (forget-me-not) ; hirsute, when the hairs are long and numerous (rose-campion) ; hispid, when they are erect and stiff (borage) ; setose, when they are long, spreading, and bristly (poppy) ; tomentose, when they are rather short, soft, and matted ; woolly, when long, appressed, curly, but not matted (corn-centaury) ; velvety, when the pubescence is short and soft to the touch (fox- glove) ; cobwebby, when the hairs are long, very fine, and interlaced like a cobweb (thistle, cobwebby houseleek). The arrangement of the hairs is also interesting. In some plants there is a double row of hairs along the stem. In the chickweed only one. This, perhaps, serves to collect rain and dew, and it is significant that the row of hairs is always opposite to the flower-stalk, which also has a single row. Now, the flower-stalk is for a considerable part of its life turned downward, with the row of hair outward. This, perhaps, may ac- count for the absence of hairs on that side of the stem. * Bunbury, " Botanical Fragments," p. 320. Fig. 20. ON LEAVES. 481 Many leaves are clothed with woolly hairs while in the bud, which afterward disappear. Thus, in the rhododendron, horse-chestnut, and other species, the young leaves are protected by a thick felt, which, when they expand, becomes detached and drops off. Many leaves are smooth on the upper side, while underneath they are clothed with a cottony, often whitish, felt. This probably serves as a protection for the stomata. In some cases the hairs probably tend to preserve the leaves from being eaten. In others, as Kerner has suggested, they serve to keep off insects — apparently with the special object of pre- venting the flowers from being robbed of their honey by insects which are not adapted to fertil- ize them. Fritz Miiller, to whom we are indebted for so many ingenious observations, gives an in- teresting case. The cater- pillar of Eunomia eagrus, when about to turn into the chrysalis (Fig. 20), breaks off its hairs and fastens them to the twig which it has selected, so as to form on each side of itself about half a dozen stiff fences, to protect it during its helpless period of quiescence. Vaucher long ago observed, though he gave no reason for the fact, that among the 3falvacem (mallows) the species which produce honey are hairy, and those which do not are glabrous. If we make a list of our English plants, marking out which species have honey and which have hairs, we shall find that we may lay it down as a general rule that honey and hairs go together. The excep- tions, indeed, are very numerous, but when we come to examine them we shall find that they can generally be accounted for. I have made a rough list of the species in the English flora which have honey and yet are glabrous. It does not profess to be exactly correct, be- cause there are some species with reference to which I was unable to ascertain by personal examination, or by reference to books, whether they produced honey or not. My list, however, comprised 110 species. Now, in the first place, of these 110 species, in sixty the entrance to the honey is so narrow that even an ant could not force its way in ; twenty are aquatic, and hence more or less protected from the visits of ants and other creeping insects ; thus we shall frequently find that, if, in a generally hairy genus, one or more species are aquatic, they are also glabrous — as, for instance, Viola palustris, Veronica anagallis, V. beccabunga, and Ranunculus aquatilis. Polygonum amphibium is peculiarly interesting, because, as Kerner has pointed out, aquatic spe- cimens are glabrous ; while in those living on land the base of the leaf TOL. XXVII. — 31 l82 THE POPULAR SCIENCE MONTHLY. produces hairs. Half a dozen are early spring plants which flower before the ants are roused from their winter sleep ; about the same number are minute ground-plants to which hairs could be no protec- tion ; three or four are night flowers ; there still remain a few to be accounted for, which would have to be considered individually, but probably the evidence is sufficiently complete to justify the general inference. Lastly, I must not omit to mention the hairs which have a glandular character. The next point to which I would call attention is the remarkable manner in which certain forms repeat themselves. In some cases, there seems much reason to suppose that one plant derives a substan- tial advantage from resembling another. For instance, Chrysanthe- mum ijiodorum, the scentless mayweed, very closely resembles the camomile in leaves, flowers, and general habit. The latter species, however, has a strong, bitter taste, which probably serves as a protec- tion to it, and of which also, perhaps, the scentless mayweed may share the advantage. These two species, however, are nearly allied to one another, and I prefer, therefore, to take as an example of mim- icry the stinging-nettle ( Urtica) and the common dead-nettle {Lamium album). These two species belong to totally different families ; the flowers are altogether unlike, but the general habit and the form of the leaves are extremely similar. How close the similarity is may be seen by the illustration (Fig. 21), taken from an excellent photograph made for me by Mr. Harman, of Bromley. The plants on the right are true stinging- nettles ; those on the left are the white dead-nettle, one of which is in flower. So close was the re- semblance that, after getting the photograph, I went back to the spot on which they were growing to assure myself that there was no mistake. It can not be doubted that the true nettle is protected by its power of stinging ; and, that being so, it is scarcely less clear that the dead-nettle must be protected by its likeness to the other. Moreover, though I was fortunate in light- ing on so good an illustration as that shown in the figure just when I had the opportunity of photographing it, still every one must have ob- served that the two species are very commonly found growing to- gether. Assuming that the ancestor of the dead-nettle had leaves possessing a faint resemblance to those of the true nettle, those in which the likeness was greatest would have the best chance of survival, Fig. 21. ON LEAVES. 483 and consequently of ripening seeds. There would be a tendency, therefore, according to the well-known principles of Mr. Darwin, to a closer and closer resemblance. I am disposed to suggest whether these resemblances may not serve as a protection, not only from browsing quadrupeds, but also from leaf-eating insects. On this part of the subject we have as yet, however, I think, no sufficient observa- tions on record. Ajuga chamcepitys, the yellow bugle, has leaves crowded and divided into three linear lobes, the lateral ones sometimes again divided. They differ, therefore, greatly from those of its allies, and this puzzled me much until one day I found it growing abundantly on the Riviera among Euphorbia cyparissias, and I was much struck by the curious likeness. The Euphorbia has the usual acrid juice of the genus, and it struck me that the yellow ajuga was perhaps protected by its resemblance. Leaves which float on the surface of still water tend to be orbicular. The water-lilies are a well-known illustration. I may also mention Limnanthenum nymph ceoides, which, indeed, is often taken for a water-lily, though it really belongs to the family of gentians, and Alisma natans, a species allied to the plantains. In running water, on the contrary, leaves tend to become more or less elongated. Subaqueous leaves of fresh-water plants have a great tendency either to become long and grass-like or Jo be divided into more or less hair-like filaments. I might mention, for instance, Myriophyllum ; Hippuris, or mare's-tail, a genus which among English plants comes next to Circaea, the enchanter's nightshade ; Mammculus aquatilis a close ally of the buttercup ; and many others. Some, again, which, when mature, have rounded, floating leaves, have long, narrow ones when young. Thus in Victoria regia the first leaves are filiform, then come one or more which are sagittate, and then fol- low the great orbicular leaves. Another interesting case is that in which Fig 2^ the same species has two forms of leaf (Fig. 22) — namely, more or less rounded ones on the surface, and a second series which are subaqueous and composed of more or less linear or finely divided segments. Mr. Grant Allen has suggested that this tendency to subdivision in subaqueous leaves is due to the absence or paucity of carbonic acid. I have ventured to suggest a different explanation. Of course it is im- portant to expose as large a surface as may be to the action of the water. We know that the gills of fish consist of a number of thin plates, which while in water float apart, but have not sufficient consist- ence to support even their own weight, much less any external force, 484 THE POPULAR SCIENCE MONTHLY. and consequently collapse in air. The same thing happens with thin, finely cut leaves. In still water they afford the greatest possible extent of surface with the least expenditure of effort in the formation of skeleton. This is, I believe, the explanation of the prevalence of this form in subaqueous leaves. Again, in still air the conditions, except so far as they are modified by the weight, would approximate to those of water ; but the more the plant is exposed to wind the more would it require strengthening. Hence, perhaps, the fact that herbs so much oftener have finely cut leaves than is the case with trees. In the Umbellifers, for instance, almost all the species have the leaves much divided — more, I need hardly say, than is the case with trees. Shrubs and trees are charac- terized by more or less entire leaves, such as those of the laurel, beech, hornbeam, lime, or by similarly shaped leaflets, as in the ash, horse- chestnut, walnut. There are, however, many groups of plants which, while habitually herbaceous, contain some shrubby species, or vice versa. Let us take some groups of this description in which the herbaceous species have their leaves much cut up, and see what is the character of the foliage in the shrubby species. The vast majority of Umbellifers, as I have just observed, are herbaceous, and with leaves much divided, the common carrot being a typical example. One European species, however, Eiipleurum fructi- cosum, is a shrub attaining a height of more than six feet, and has the leaves (Fig. 23) coriaceous, and oblong -lanceolate. ■flk1 Fig. 23. The common groundsel (Fig. 24), again, is a low herb writh much cut leaves. Some species of jSenecio, however, are shrubby, and their leaves assume a totally different character, Senecio laurifolius and S. populifolius having, as their specific names denote, leaves respectively resembling the laurel and poplar. In the genus Oxalis, again, to which the shamrock belongs, there is a shrubby species, 0. laureola, with leaves like those of a laurel. ON LEAVES. 485 I would venture, then, to suggest these considerations as throwing light on the reason why herbaceous plants so often have their leaves much cut up.* Next let me say a few words on the reasons why some plants have broad and some narrow leaves. Both are often found within the limits of a single genus. I have ventured to indicate the distance between the buds as a possible reason in certain cases. It would not, however, apply to herbaceous genera such as Plantago or Drosera. Now, Drosera rotundifolia (Fig. 25) has the leaves nearly orbicular, Fig. 25. Fig. 26. vhile in D. anglica (Fig. 26) they are long and narrow. Plantago media (Fig. 27) has ovate leaves, while in P. lanceolata (Fig. 28) they are lanceolate, and in P. maritima nearly linear. More or less similar cases occur in Ranunculus. These differences depend, I believe, on the attitude of the leaf, for it will be found that the broad-leaved ones are horizontal, forming a rosette more or less like that of a daisy, while the species with nar- rower leaves carry them more or less erect. In the daisy the rosette lies on the ground, but in other cases, as in Daphne (Fig. 29), it is at the end of a branch. Any one who has looked with an observant eye at the vegetation of hot, dry countries must have noticed how much the general char- acter of the vegetation differs from that which prevails in a climate like ours. There is a marked increase of prickly, leathery, and aromatic species. The first two characteristics evidently tend to protect the leaves. As regards the third, Mr. Taylor, f in his charming book on * Mr. Grant Allen, who had been also struck by the fact that herbaceous plants so often have their leaves much cut up, has suggested a different explanation, and thinks it is due to " the fierce competition that goes on for the carbon of the air between the small matted undergrowth of every thicket and hedge-row." f Page 311. 486 THE POPULAR SCIENCE MONTHLY. " Flowers," has pointed to the power which, as Tyndall has shown, the spray of perfume possesses to bar out the passage of heat-rays, and has suggested that the emission of essential oils from the leaves of many plants which live in hot climates may serve to protect themselves against the intensely dry heat of the desert sun. Fig. 27. Fig. 28. I am rather disposed to think that the aromatic character of the leaves protects them by rendering it less easy for animals to eat them. In still drier regions, such as the Cape of Good Hope, an unusually large proportion of species are bulbous. These, moreover, do not be- long to any single group, but are scattered among a large number of very different families : the bulbous condition can not, therefore, be ex- plained by inheritance, but must have reference to the surrounding circumstances. Moreover, in a large number of species the leaves tend to become succulent and fleshy. Now, in organisms of any given form the surface increases as the square, the mass as the cube, of the dimensions. Hence, a spherical form, which is so common in small animals and plants, and which in them offers a sufficient area of surface in propor- tion to the mass, becomes quite unsuitable in larger creatures, and we find that both animals and plants have orifices leading from the outside to the interior, and thus giving an additional amount of surface. But in plants which inhabit very dry countries it is necessary that they should be able to absorb moisture when opportunity offers, and store it up for future use. Hence, under such circumstances fleshy Fig. ^9. ON LEAVES. 487 stems and leaves are an advantage, because the surface exposed to evaporation is smaller in proportion than it would be in leaves of the ordinary form. This is, I believe, tbe reason why succulent leaves and stems are an advantage in very dry climates, such as the Canaries, Cape of Good Hope, etc. The genus Lathy rus, the wild pea, contains two abnormal and interesting species, in which the foliaceous organs give the plant an appearance very unlike its congeners. Fig. 30 represents L. niger, with leaves of the ordinary type. In the yellow pea (L. aphaca, Fig. 31), the general aspect is very different, but it will be seen on a closer Fia. 30. Fig. 31. inspection that the leaves are really absent, or, to speak more correctly, are reduced to tendrils, while the stipules, on the contrary, are, in compensation, considerably enlarged. They must not, therefore, be compared with the leaves, but with the stipules of other species, and from this point of view they are of a more normal character, the prin- cipal difference, indeed, being in size. The grass pea (L. nissolia, Fig. 32) is also a small species. It lives in meadows and the grassy borders of fields, and has lost altogether, not only the leaves, but also the tendrils. Instead, however, of en- larged stipules, the functions of the leaves are assumed by the leaf- stalks, which are elongated, flattened, linear, ending in a fine point, and, in fact, so like the leaves of the grasses among which the plant lives that it is almost impossible to distinguish it except when in flower. For a weak plant growing among close grass, a long linear leaf is, perhaps, physically an advantage ; but one may venture to sug- gest that the leaves would be more likely to be picked out and eaten if they were more easily distinguishable, and that from this point of view also the similarity of che plant to the grass among which it grows may also be an advantage. 488 THE POPULAR SCIENCE MONTHLY. Fia. 32. In looking at foliage I have often been much puzzled as to why the leaves of some species are tongue-shaped, while others are lobed. Take, for instance, the black bryony ( Tamus communis) and the com- mon bryony {Bryonia dioica). Again, why are the veins in some leaves pinnate, like those of the beech and elm, and others palmate, as in the maple and sycamore ? My first idea was that this might have reference to the arrangement of the woody fibers in the leaf -stalk. If we make a sec- tion of the stalk of a leaf, we shall find that in some cases the woody fibers are collected in the middle, while in others there are sev- eral distinct bundles, separated by cellular parenchyma. My first idea was that each of the primary ribs of a leaf might repre- sent a separate woody fiber in the leaf- stalk, so that leaves with a single bundle of woody fibers would be pinnate ; those with several distinct bundles, palmate. The first species which I examined fa- vored this view. The melon, geranium, mal- low, cyclamen, and other species with palmate leaves, had, sure enough, several woody fibers ; while, on the contrary, the laurel, rhododendron, privet, beech, box, castanea, arbutus, phillyrea, and other leaves with pinnate veins, had one central bundle. But I soon came across numer- ous exceptions, and had to give up the idea. I then considered whether the difference could be accounted for by the mode of growth of the leaf, and I am still disposed to think that it has some bearing on the subject, though this requires further study. The next suggestion which occurred to me was that it might be connected with the " prefoliation " or arrangement of the leaves in the bud. The first palmate leaves which I examined were what is called " plicate," or folded up more or less like a fan ; while the leaves with pinnate veins were generally " conduplicate," or had the one half applied to the other. But, though this was true in many cases, it was not a general rule, and I was obliged to give up this idea also. It then occurred to me to take climbing plants, and see whether I could find any relation between palmate and tongue-shaped leaves on the one hand and the mode of growth on the other — whether, for in- stance, the one turned generally up, the other down ; whether the one were generally twining and the other clasping, or vice versa. All these suggestions one by one broke down. Among monocotyledons, however, the tongue-shaped preponderates greatly over the palmate form of leaf. With very few exceptions, the ON LEAVES. 489 Fig. 33. forms of the leaves of climbing monocotyledons are in fact just such as would be obtained by widening more or less the linear, grass-like leaf which is so prevalent in the class. This, then, raises the question whether the heart-shaped leaf is the older form from which the palmate type has been gradually evolved. Let us see whether we can find any evidence bearing on this question in what may be called the embryology of plants. The furze, with its spiny prickles, belongs to a group of plants which, as a general rule, have trifoliate or pinnate leaves. Now, if we examine a seedling furze (Fig. 33), we shall find that the cotyledons are succeeded by sev- eral trifoliate leaves, with ovate leaflets. These gradually become narrower, more pointed, and stiffer, thus passing into spines. Hence, we can hardly doubt that the present furze is descended from ancestors with trifoliate leaves. I have al- ready referred to other cases in which the young plants throw light on the previous condition of the species {ante, p. 12). Now we shall have no difficulty in finding cases where, while in mature plants the leaves are more or less lobed and palmate, the first leaves succeed- ing the cotyledons are heart-shaped. This would seem to point to the fact that when in any genus we find heart-shaped and lobed leaves, the former may represent the earlier or ancestral condition. The advantage of the palmate form may perhaps consist in its bringing the center of gravity nearer to the point of support. Broad leaves, however, are of two types : cordate, with veins following the curvature of the edge ; and palmate or lobed leaves, with veins running straight to the edge. The veins contain vascular bundles which con- duct the nourishment sucked up by the roots, and it is clearly better that they should hold a straight course, rather than wind round in a curve. As the nourishing fluids pass more rapidly along these vascular bundles, the leaf naturally grows there more rapidly, and thus assumes the lobed form, with a vein running to the point of each lobe. On the whole, we see, I think, that many at any rate of the forms presented by leaves have reference to the conditions and requirements of the plant. If there was some definite form told off for each species, then, surely, a similar rule ought to hold good for each genus. The species of a genus might well differ more from one another than the varieties of any particular species ; the generic type might be, so to say, less closely limited ; but still there ought to be some type charac- teristic of the genus. Let us see whether this is so. No doubt there are many genera in which the leaves are more or less uniform, but in them the general habit is also, as a rule, more or less similar. Is this 49° THE POPULAR SCIENCE MONTHLY. the ease in genera where the various species differ greatly in habit ? I have already incidentally given cases which show that this is not so, but let us take some group — for instance, the genus Senecio, to which the common groundsel (Fig. 24) belongs, as a type well known to all of us — and look at it a little more closely. The leaves of the common groundsel I need not describe, because they are familiar to us all. This type occurs in various other species of more or less similar habit. On the other hand, the fen Senecio (S. paludosus) and the marsh Senecio (S. palus- tris), which live in marshy and wet places, have long, narrow, sword-shaped leaves, like those of so many other plants which are found in such localities. The field Senecio (S. cam- pestris, Fig. 34), which lives in meadows and pastures, has a small terminal head of flowers springing from a rosette of leaves much like those of a common daisy (JSellis perennis) ; a Madagascar species, as yet I believe un- named, is even more like a daisy. Senecio junceus looks much like a rush ; S. hypo- chcerideus, of South Africa, strikingly resem- bles a hypochceris, as its name denotes. A considerable number of species attain to a larger size and become woody so as to form regular bushes. S. buxifolius has very much the general look of a box, S. vagans of a privet, S. laurifolius of a laurel, ericcefolius of a heath, pinifolius of a fir, or rather a yew. Again, some species are climbers : S. scandens and S. macroglossus have leaves like a bryony ; S. araneosus and S. tamoides like a smilax or (yam) tamus ; S. tropceoUfolius like a tropseolum. Among the species inhabiting hot, dry regions are some with swol- len, fleshy leaves, such as S. haworthii, from the Cape of Good Hope, and S. pteroneura, from Magador. Senecio rosmarinifolius, of the Cape, is curiously like a rosemary or lavender. Lastly, some species may almost be called small trees, such as S. popidifolius, writh leaves like a poplar ; and S. amygdaloides, like an almond. I might mention, if space permitted, many other species which, as their names denote, closely resemble forms belonging to other groups — such, for instance, as Senecio lobelioides, erysimoides, bupleurioides, verbascifolius, juniperinus, ilicifolius, acanthifolius, linifolius, platani- folius, graminifolius, verbenefolius, rosmarinifolius, coronopifolius, chenopodifolius, lavanderisefolius, salicifolius, mesembryanthemoidee, digitalifolius, abietinus, arbutifolius, malvsefolius, erodiifolius, halimi- folius, hakesefolius, resedsefolius, hedertefolius, acerifolius, plantigineus, castaniaefolius, spiroeifolius, bryonioefolius, primulifolius, and many THE FUTURE OF NATIONAL BANKING. 491 more. These names, however, indicate similarities to over thirty other perfectly distinct families. It seems clear, then, that these differences have reference not to any inherent tendency, but to the structure and organization, the habits and requirements, of the plant. Of course, it may be that the present form has reference not to existing, but to ancient, conditions, which renders the problem all the more difficult. Nor do I at all intend to maintain that every form of leaf is, or ever has been, neces- sarily that best adapted to the circumstances, but only that they are constantly tending to become so, just as water always tends to find its own level. But, however this may be, if my main argument is correct, it opens out a very wide and interesting field of study, for every one of the almost infinite forms of leaves must have some cause and explanation. — Contemporary Review. +»» THE FUTURE OF NATIONAL BANKING. By E. E. LELAND. THE ever-recurring question as to the methods which should be adopted for supplying the country with currency promises soon again to demand attention, and to be beset with all its old-time per- plexities. It is the riddle which is presented in turn to each civilized nation, and, although the penalty of default is severe, no satisfactory answer has as yet been found. The national banking system, which has frequently been declared to be the best yet devised, can not be said to offer a solution, for, al- though it served its temporary purpose very well, it lacks, so far as its currency is concerned, the essential element of permanency, being based upon a public debt that, fortunately, is not a perpetuity. Re- cently grave concern has been felt and expressed over the prospective contraction, if not total withdrawal, of the national-bank circulation which is likely to result from the diminished supply of Government bonds. The prospect is generally deplored. Sundry bills were intro- duced into the late Congress, looking to a mitigation or postponement of the consequent evils, but no conclusive action was taken, nor is there much reason to expect that the subject will receive serious con- gressional consideration until it compels attention. It is true that the advocates of a let-alone policy might justify their course by pointing out that the danger of a currency contrac- tion does not appear so imminent as it did nine months ago. Owing to diminished revenue, there have been no recent bond calls, and the reduction of the debt is for the time arrested. But the prices of bonds have so enhanced as substantially to rob the business of issuing 492 THE POPULAR SCIENCE MONTHLY. notes of profit, and, even were the banks willing to keep out their cir- culation for the small recompense which now comes to them, little reli- ance can be placed upon a continuance of the present conditions. The reduction of the Government debt will be resumed, nor is the delay likely to give more time than will be needed in which to devise and put into operation some other plan for furnishing a currency supply. There are many men — so many as to constitute a party considerable in number — who have an ever-ready remedy to administer for this or any similar trouble which threatens our financial system ; that is, an additional supply of legal-tender notes. It is not intended here to dis- cuss this proposition. The evils which are certain to attend an un- limited or largely increased issue of legal tenders have so often been shown, and the greenback clamor has so far died away, that there are grounds for the hope, which let us cherish, that a majority will not call for a Government paper circulation, albeit the United States Supreme Court has decided that Congress has uncontrolled power to create and regulate such an issue. For the purpose of this paper, therefore, it will be assumed that resort will not be had to legal-tender notes for a supply of paper money when the bond-secured national-bank notes shall be withdrawn. There is a school of economists — a title that can not properly be applied to the greenbackers — who hold that it is radically unsound and productive of evil for banks to assume the function of furnishing money ; who maintain that there should be no money other tban a metallic currency, or one which would in all respects act precisely as a metallic currency acts, because not only based upon but actually representing specie of a like amount deposited and held for its redemp- tion. This school would doubtless regard the time of the retirement of national-bank notes as presenting an opportunity for inaugurating their system too good to be lost. Very recently suggestions in this line have been made and widely considered as, perhaps, offering solu- tions of both the paper currency and the silver problems ; and, indeed, if the experiment were a wise one, it never could be made with less prospect of serious disturbance during the transition period, for the process is already begun by the issue of gold and silver certificates which could be increased, if specie were forthcoming, as bank-notes were withdrawn. If any plan embodying this idea were adopted, we should then have a system somewhat similar to that by which England has been supplied with paper money since the adoption of Peel's act in 1844. Under that act the Bank of England is now authorized to issue notes to the amount of fifteen million pounds sterling upon Gov- ernment securities ; beyond this sum the amount of circulation is de- termined solely by the amount of bullion which the public chooses to deposit, for the bank is bound to buy gold bullion at the mint price, whenever offered. The banking department and the issue depart- THE FUTURE OF NATIONAL BANKING. 493 merit are separately managed, and of the latter the directors have no control. Professor Price says that it is not a department of the hank in any sense ; that " it is a self-acting institution of the state, work- ing on the bank's premises, by rules laid down by the state, and abso- lutely beyond the control of the directors." If the terms of Peel's act were at all times rigidly adhered to, this description of the operation of the issue department would be correct. As a matter of fact, however, they are not adhered to, but are sus- pended in times of financial stress, and the directors assume control of the issue department for the relief of the strain upon the banking de- partment and the business community. Three times since the adop- tion of the act has its operation been suspended. The supposition that a " suspension of the act " involves a suspension of specie payments is, perhaps, still common enough to warrant an explanation of its true nature. The Bank of England is the custodian of the principal portion of the reserve of all the banks and bankers of England, and to it the latter must look for money to meet the excessive and unusual demands that are made upon them in time of panic. At such times, therefore, a rapid inroad is made upon the bank's supply of gold, and, if the act of 1844 continues in force, a point is soon reached where the directors are compelled, for self-protection, to cease discounting even upon the best securities. Whenever the strain becomes unendurable, an appeal is made to the Government, through the Chancellor of the Exchequer, to suspend the act. If granted, the legal restrictions upon the bank's note-issues are removed, and the directors are authorized largely to increase their issue without reference to the amount of bullion in their vaults ; the effect of which is that for the time both departments of the bank are under the management and control of the directors. They are not likely to use this privilege recklessly, for the obligation to redeem their notes in gold on demand remains in full effect. More- over, for some reason not wholly apparent, it has become a custom — so far as three instances can make a custom — for the Government to stipu- late that the bank shall charge a very high rate of interest, say ten or twelve per cent, upon the extra note-issues, the profit thereon to go to the state. The result of this is* that prudence and self-interest com- bine to make the directors use the powers conferred upon them most sparingly, and they do so. In but one instance has there been an over- issue. This was in 1857, and to the extent of eight hundred thousand pounds. In 1847 and in I860 the fact of suspension proved sufficient to allay the panic and to avert, at least, its worst consequences. A recent writer recommends the mechanical and local separation of the issue department from the Bank of England to a Government office, as tending to the propagation of clearer ideas on the subject of note currency. No suggestion is offered as to the way in which relief could be afforded in emergencies similar to those which have hereto- 494 THE POPULAR SCIENCE MONTHLY. fore been met by extending the bank's powers, nor is it obvious how any could be given except through the agency of the bank. Extending the comparison between the English system and that of the United States, with the national-bank notes retired, the legal tend- ers, although much greater in volume, might be likened to the seventy- five million dollars that the Bank of England issues against its securi- ties, while the bank's specie-secured issues would find their parallel in the gold and silver certificates. These now amount to something more than two hundred and fifty million dollai's. They have not very far to go before they would equal the national-bank notes outstanding, and the expediency of largely increasing the issue is freely discussed. But in the workings of the two systems here compared there would be an important difference. When the act of 1844 was being urged, its advocates recognized that in extreme cases a rigid adherence to its provisions might be mischievous, and special governmental interference be found neces- sary. Experience has shown that such compelling emergencies do arise. Warned by this, Mr. Lowe, Chancellor of the Exchequer, introduced into the House of Commons in 1873 a bill providing for automatic suspension, so to speak. He proposed that the Government might lawfully suspend the bank act when certain conditions obtained, conditions presumed to be indicative of a panic ; but the bill was not received with favor, and was withdrawn. AVhat the effect of a strict adherence to the act in time of panic would be, it is difficult to pre- dict— it has never been tried. It is not easy to see how, even if it were made lawful, relief could be given in the case of a strictly governmental issue, consisting, for example, of specie certificates and legal tenders. If additional issues of the latter were authorized, how, in time of peace, would they be put .dioat ? Certainly few would be willing to have the Treasury Depart- ment take up the business of banking and make advances on miscella- neous securities. But the time would certainly come when the tem- porary relief given by clearing-house certificates would be found to be, or at least be thought to be, inadequate, and an increase of currency be demanded. Could there be any assurance that the power to make such increase resting in Government officials would be exercised with the caution shown by the Governor and Company of the Bank of Eng- land, who are restrained by considerations both of prudence and profit ? An illustration of the course likely to be pursued was furnished in 1872-73, when forty-four million dollars of legal tenders, which had been retired by Secretary McCulloch, were dubbed a reserve, the re- issue of which was demanded and granted to the extent of twenty-six million dollars. There are ample grounds for the fear that any sys- tem under which the Government should furnish, in whatever form, the whole supply of the paper money of the country, would keep us constantly on the lee -shore of an inconvertible paper currency, THE FUTURE OF NATIONAL BANKING. 495 the capacity of which for working mischief has often been pointed out. It is not probable, however, that there will be any wide departure from existing methods. Outside of the straggling ranks of the greenbackers the national-bank notes are regarded with favor. It can not be gainsaid that the period during which they have been in existence has been a very comfortable one, so far as a good currency for the people could make it so. Whatever theoretical objections there may be to the system, it has worked singularly well, is justly popular, and it is easy to understand why its probable restriction and ultimate discontinuance should be looked forward to with concern. There has been little or nothing in the way of suggestion as to what can be done to perpetuate the national-bank issues. Various plans have been proposed for prolonging their existence ; but closely adhering, as all these plans do, to the theory of a bond-secured cur- rency, they are confined within narrow limits. Secretary Folger and Secretary McCulloch, Comptrollers Knox and Cannon, have substantially agreed in their reports for two years past in recommending — 1. The removal of the tax on bank circulation ; 2. An increase of the percentage of currency which the banks may issue against bonds deposited ; 3. The conversion of long bonds into three, or two and a half per cents, the latter being less likely to be withdrawn for reasons having no reference to the amount of circula- tion needed ; and bills were introduced in both Houses of the last Con- gress providing for the practical application of these recommendations. Their adoption would, however, afford but temporary relief. It would have the merit, no small one it may be said, of enabling us to travel along the well-known road for a while longer, but it would only post- pone the day when a solution of the currency problem must be con- fronted. The true solution has, by some of the gentlemen referred to, been declared to be a reduction of the redundant revenue sufficient to retard the retirement of bonds, and finally to arrest it when their volume shall have reached, or closely approached, the amount requisite to secure the national-bank circulation. To retard the payment of the public debt by reducing taxation would probably be expedient, it certainly would be popular ; but wholly to arrest payment, and, for such a purpose, maintain the debt at a fixed sum, would be another and a very questionable matter. Moreover, a currency thus regulated as to volume would lack the important element of adaptability, or, as it is sometimes called, elas- ticity, for it is not likely that any one would go so far as to suggest that the bond debt should be increased and decreased in accordance with the demands for currency — a method which, if not otherwise questionable, would be so clumsy and tardy in its operation as to serve but poorly. Who in such case should decide what amount of cur- 496 THE POPULAR SCIENCE MONTHLY. rency and consequently of bonds would be needful ? The Secretary of the Treasury or the congressional committee who should be called upon to determine this point would require the same degree of omnis- cience that would be required to fix the proper limit of irredeemable legal tenders. The objections to any arbitrary regulation of the vol- ume of currency have been so often pointed out as to make needless their recital in this connection. To maintain, for the purposes of bank-note security, a Government debt anything in excess of the Government's needs, would be, in effect, to levy a tax upon the community at large for distribution as a bounty on bank-note circulation. It may be said that the benefits inuring to the issuers would be slight and incidental — a not undue reward for the service rendered— and that the real purpose would be the protec- tion of the note-holder, which protection would be worth more than its cost. Thus stated, the proposition would be to make the note- holders a preferred class of creditors, secured at the public cost. It would be pertinent to ask here, By what logical method is the con- clusion reached that this preference should be given to the note-hold- ers alone ? Are there not other classes of creditors with equal claims for protection ? The depositors in savings-banks, the beneficiaries of life-insurance policies, and divers other corporate and private trusts, are now very largely secured by Government bonds, and it is not easy to see why, if the note-holders are to have special protection, these can not with perfect justice ask that they too shall continue to be cared for by the Government. That such demands should be acceded to few will assert, but it would be quite as proper for the Government to furnish security for all as for a part. But it is idle to discuss this proposition at length. Whatever differences of opinion there may be as to the rate at which reduction of the debt should go on, there is little difference as to the general principle that it should be reduced as fast as may be consistent with a proper distribution of the burden. The proposition that it is a good thing to pay one's debts, when abundantly able to do so, is sound, and it applies to an aggregate of individuals — the state — precisely as it does to a single individual. Public opinion will doubtless demands it certainly would be right in demanding, that the volume of the public debt shall be regulated without reference to national-bank-note issues ; the idea that it should, or might with propriety, be regulated with reference to their needs, is radically unsound. Nor, it maybe added, are there any reasons, economic or political, for a resort to such strained methods. That a paper currency is one of the requirements of a great com- mercial country is generally admitted. That such a currency can best be furnished by banks of issue, if not so generally admitted, would seem to be demonstrated by universal custom among civilized nations. The issuance of circulating notes is a legitimate, if not necessary, func- tion of the business of banking. It is one of the forms of the compli- THE FUTURE OF NATIONAL BANKING. 497 cated system of credit which has made commercial growth possible, nor is there any reason why this particular form of banking obligation, constituting, as it does, but a minor part of the total, should, when cre- ated, have other or better safeguards than the remainder. The security furnished by the capital of the banks, by the ability and integrity of their management, aided by governmental supervision, which must needs serve for the greater part of their liabilities, should be adequate for the whole. The checks and precautions, the discrimination, which are applied to the use of credit in other branches of banking, the pro- tection which is found to answer for depositors and holders of checks and drafts, should also be sufficient for the holders of that particular class of " memoranda of claims " known as bank-notes. That this protec- tion can be made practically efficient is amply proved by the history of the national banking system in the United States. During an ex- perience of more than twenty years the average annual loss to deposit- ors has been only one twentieth of one per cent of the total. The public have become so accustomed to the use of a bond-secured currency, and have so generally credited the satisfactory results to the feature of special security, that the suggestion of an unsecured cur- rency, or, rather, a currency not secured by special deposits, is not likely, at the outset, to be received with favor. To many it will re- call the days of wild-cat banking, when the country was flooded with money that was practically irredeemable, and wide-spread and serious loss was inflicted on the community, especially upon the poorer classes, by having worthless issues forced upon them. But there is little dan- ger and no need of a revival of that vicious system. The lessons of the past have not been wasted ; nor are we a " na- tion of rascals," in spite of sundry recent revelations of rascality and weakness. More and more, as civilization advances, does the tendency of people to trust each other increase. Yearly the average of pru- dence and trustworthiness grows larger. If not because of a stronger sense of moral obligation, then because of a better appreciation of the necessity therefor in the conduct of business, men show a growing respect for each other's rights, and place a greater reliance upon the relations of contract. Mr. Spencer says, " Given a nation of perfectly honest men, and nearly all trade among its members may be carried on by memoranda of claims." We have not, it is needless to say, reached an ideal state of perfect honesty — far from it. The adoption, therefore, of an abso- lutely free banking system, without limitations or restrictions, would be an experiment too hazardous to be tried. There is, however, a de- gree of honesty which suffices to maintain a credit system of great ex- tent and complexity, involving the use of enormous sums of promises to pay, and the extension of that system to cover the use of the partic- ular form of promises to pay known as bank-notes is logical, natural, and, with proper restrictions, safe. TOL. XXVII. — 32 498 THE POPULAR SCIENCE MONTHLY. It is true that notes which pass from hand to hand as money are not scanned as closely as are other evidences of debt, nor can there be the same discrimination exercised in their use. They must, if circu- lated in small denominations, of necessity be taken by many who have no means of forming correct conclusions as to the soundness of the issues, and who can least afford to suffer loss. But the circulation of small notes of any sort is to be deprecated. Adam Smith pointed out the difference in the forms of money required for dealers and for con- sumers ; that for the uses of the latter, paper money is not fitted, no matter what its form or security. The soundness of this view has been largely discussed since his time, but the preponderance of opin- ion has been in its favor. Mr. McCulloch, in his recent report, recom- mended the discontinuance of small notes. It would bring out a large amount of silver and small gold, which furnish the best kind of money for the smaller transactions of trade, and afford the best possible pro- tection for the small dealers, the wage-earners — men, women, and children — who suffer most from a defective currency.* If small notes were retired, the smaller savings, the stocking-hoards, would consist of gold and silver, and obviously it is best that this part of the coun- try's reserve — no inconsiderable part — should be of specie. The ag- gregate issue of legal-tender and national-bank notes of denominations under ten dollars is about two hundred and twenty million dollars. It is probable that nearly this entire amount could be replaced with gold and silver before the point of specie saturation would be reached. Such a volume of hard money would supply the best obtainable guarantee against currency disturbances. That, if relieved from the function of furnishing wage and pocket money, a bank currency, suited for the larger operations of trade, and yet not handicapped with the obligation of special bond deposits, could be established with safety, may be asserted. That banks of issue can be safely conducted and furnish a sound currency has been sufficiently shown under conditions far more unfavorable than now obtain in the United States. The Scotch banks are examples. So well have they been conducted that Professor Jevons admitted that their system would be an excellent one for general adoption, " if we were all Scotchmen." It may be fairly doubted, however, whether the satis- factory results in Scotland are wholly due to exceptional integrity, sagacity, and caution on the part of Scottish managers. May it not be that the bank-currency system, properly conducted, has had a fairer trial in Scotland than elsewhere ? One does not need to be very old to remember when this country, especially the West, was dependent upon a paper currency that was, for the most part, of a very trashy kind ; and to remember, also, that * That the forced circulation of a debased coinage, by this or any other method, is not intended to be advocated, need hardly be explained ; but a discussion of the silver question is no part of this paper. THE FUTURE OF NATIONAL BANKING. 499 even then, and in that region, there were notable exceptions. Bank offi- cials will remember how a stray note of the ugly issues of the State Bank of Indiana, or the Wisconsin Marine and Fire Insurance Com- pany, coming in with a pile of gaudy wild-cats, used to " shine out like a good deed in a naughty world," and was promptly sorted out and laid away as a part of the reserve. Those banks, with a few others, hav- ing relatively very large issues, were conducted safely through the vicissitudes of those days, promptly redeeming their notes on the ad- vent of the national system without the loss of a dollar to the holders. But the honestly and prudently conducted banks of that period were not numerous nor strong enough to redeem the vices nor avert the evils of paper-money banking as it was then carried on. The story of recklessness, fraud, and suffering does not need to be retold, and no one would be willing to see the way opened for a repetition of its experiences. The conditions now are very different. The operation of the na- tional banking system for twenty years has brought to its management a class of trained and educated bankers, who are, for the most part, fit custodians of the people's money, and to whom might be intrusted the work of furnishing paper money for the country with greater economy and less risk of loss than would attend the adoption of any other system. The machinery is at hand, is in excellent working or- der, and would need but slight modifications to fit it to perform its work after the obligation to deposit Government bonds against note- issues had been canceled. There are now over twenty-six hundred national banks in operation. They have been organized and located, not with reference to issuing currency, but to supply the legitimate needs of the business community. To guard against the formation of banks for purposes of circulation only, the right to issue might for the present be confined to those now in existence, with a permanent pro- vision that such right should be extended to new banks only after three or five years of successful operation : no permits to be granted except under the conditions now imposed as to location, ratio of capi- tal to population, and of circulation to paid-up capital. A Govern- ment bureau should continue its supervision, and should engrave, print, and furnish the note impressions as a precaution against the possibility of over-issues ; this and any other labor or expense imposed upon the bureau to be paid for by a continuance of the tax on cur- rency. Existing regulations as to reports, examinations, and control in cases of bankruptcy should be maintained, and it might be well to give preference to the claims of note-holders. Notes should, of course, be redeemed in coin or legal tenders on demand, with provision for central redemption. At present there is, practically, no redemption except of mutilated notes. Under the system suggested redemption would be real, and the amount of note circulation be, as it should be, regulated by trade requirements, with no danger of a sudden and un- 5oo THE POPULAR SCIENCE MONTHLY. necessary increase, such as has been seen in the former history of free banking. The question of the constitutional power of Congress to authorize such a system can only be alluded to. It would very likely be raised ; but it may be assumed that it would not prove an insuperable objec- tion. It might be made a condition of granting charters or licenses to banks that they should be required to lend a certain percentage of their capital to the Government whenever called upon, and also under proper restrictions be made depositories of public moneys ; thus, as has been suggested, doing away with the expensive and primitive system of local sub-treasuries. Bankers to make money on their issues must keep them in circula- tion, which could be done by the same means, and those only, that are employed to build up a line of deposits ; that is to say, they must establish their credit by promptly performing their engagements. Governmental interference should be exercised solely with reference to insistence upon such performance. That in some cases there would be mismanagement, dishonesty, and consequent loss, in the future as in the past, is certain ; but the con- trol and supervision of banking should not, any more than that of other branches of business, be regulated upon the hypothesis of fraud. The losses which might come would be comparatively small, would follow quickly upon their causes, would have the advantage of being directly traceable, and so permit the prompt application of remedial measures. With the existing means of swift communication, with the wide distribution of national banks, and the watchfulness which they employ toward each other, and, finally, with the smaller transactions carried on by means of specie, the losses upon bank-notes would not only be small, but would, for the most part, fall upon the banks them- selves, they being the constant custodians of the greater part of the currency ; and they could be trusted to see to it that only such circu- lated as was worthy to have circulation. This brings us to a suggestion which is put forth with much hesi- tation, and only as a suggestion, notwithstanding it is believed that it is sound in principle, and might be made safe in practice. It is simply that the banks should assume the risk, and, as a whole, undertake to protect the rest of the community from loss upon note-issues. To effect this it would only be necessary, so far as legislation is concerned, to continue in force that provision of the existing law which makes national-bank notes a legal tender to national banks. It would seem to be well-nigh certain that the banks could assume this risk of loss, whatever it might prove to be, and still the business of issuing notes afford a larger margin of profit than it now does. For this would be but an application of the insurance principle to one class of the acci- dents to which the banking business is liable. The banking interest, as a whole, would undertake to indemnify the public against losses THE FUTURE OF NATIONAL BANKING. 501 arising from tbe failure of individual banks to redeem their notes. As to the nature and extent of such losses, they already have a much bet- ter basis for estimating them than was available to life or fire and ma- rine insurance companies in their inception. A perfectly trustworthy " table of experience " is supplied by the record of the losses to deposi- tors in national banks for the last twenty years ; these, as before stated, have been only one twentieth of one per cent per annum. This interval covers two periods of panic and consequent depression, and may be presumed to have included most, if not all, of the vicissitudes of the business. If from abundant caution the estimate of probable loss should be put at tenfold that which past experience with the na- tional system has shown, and the present Government tax on currency be added, we should have a total of one and a half per cent on the volume of currency to cover losses and expenses. The premium out of which to pay this charge would be the interest on the excess of the average amount of currency in circulation over the reserve required to be held against it, or say from three to seven per cent, varying with the state of the money market and the location of the banks. This certainly offers an ample margin. The idea is not altogether novel even in its application. It was adopted in the case of the various branches of the State Bank of Indi- ana, and worked satisfactorily. Slightly modified, it is applied by the guarantee companies, which, for a much smaller premium, guarantee employers against the fraud and insolvency of their servants. The suggestion may be somewhat startling to bankers, who, as a class, are proverbially and properly conservative, but the soundness of the pi*in- ciple which underlies it has been demonstrated by long experience and is constantly finding wider application. Bankers daily risk, without thought of fear, far larger sums than such an insurance of currency would involve upon guarantees that are much less stable, that is upon the indemnity furnished by insurance companies, which, both as re- gards sums at risk and premiums charged, conduct their business on comparatively small margins. Should the liability seem too great if extended commonly to all the banks, geographical districts might be created with redemption centers, the mutual guarantee of the banks not to extend beyond the limits of their districts. Objection may be taken that such a system of currency would in- crease the profits of banking. That it would do so, in some degree, is probable, but it is not in the interest of that business that the sugges- tion is made. The public have the deepest interest in the avoidance of perturbations or disturbance in the currency supply. If the prin- ciples presented be sound, and their application correct, it would seem to be clear that the existing banks could continue their present circu- lation, and guarantee it, with safety to themselves and their note- holders ; and that thus might be accomplished the desideratum of paying off the Government bonds, when the time comes, without can- 502 THE POPULAR SCIENCE MONTHLY. celing the bank circulation. If, later, need should arise for a greater volume of currency, arrangements might be devised for increasing the circulation of existing banks or creating new ones. Obviously, the banks themselves should, in such event, have a voice in determining the methods by which this should be done, and in the selection of the persons or corporations to whom the right of issue should be extended. Similarly, in regard to examinations ; thoroughness should be assured, nor need this be difficult. When the banks of a clearing-house are called upon to care for some embarrassed member, a brief inspection enables them correctly to determine the real condition of the appli- cant ; they have a direct interest in getting at the facts. Examin- ers should be chosen, or at least nominated, by the banks. The bureau which supervises the other operations of the banks could, with but little addition of labor or responsibility, conduct the redemption of the notes of insolvent banks, and levy and collect what- ever assessments might be needed to make good deficiencies. But it is needless to enter into an elaboration of details ; they would present no serious difficulties when, if ever, it became necessary to deal with them. It may be said of any suggestions in this connection, that, what- ever opinion may be held of their worth, they are not premature, nor without value, if they provoke the attention of men who are able to do better thinking. The occasional desertion of national banks to the ranks of state institutions, and the contemplated separation of others, as well as the prospect of enforced relinquishment of circulation by all, indicate, plainly enough, that it is none too soon to consider some modification of the national banking system, if it is to be maintained, and it has worked too well to be needlessly abandoned. It would probably be assuming too much to expect that any system of bank issues without special security, however surrounded by safe- guards, would find present favor with our national legislators, or in- deed secure many adherents. A few years ago, some of our ablest financiers, both in and out of Congress, predicted that free banking would follow swift upon the resumption of specie payments ; but pres- ent indications do not point that way. More crude and less scientific expedients are likely first to be tried — and to fail. But it seems not over-presumptuous to predict that ultimately resort will be had to some form of that system. Its convenience and economy are obvious, and will assert themselves. The evils which it involves are such, and such only, as are inherent in the general conduct of business, such as will inhere so long as honesty and mutual confidence are imperfect ; as these improve, the risks will lessen. While the causes exist, the losses will fall ; there can be no perfect safeguards, nor of such as are possible can a paternal government afford the best : they must be looked for at the hands of the people themselves. THE MECHANICS OF HANGING. 503 THE MECHANICS OF HANGING. By JAMES BARR, M. D. ' AS the subject of the mode of carrying out executions has recently engaged public attention, the present is perhaps an opportune time for discussing the question in its scientific and humane bearings, so that some more definite ideas may prevail as to the best method of hanging, and that the details may not be entirely left to the caprice of the executioner. When the law requires the death-sentence to be meted out at the end of a hempen rope, the dictates of humanity de- mand that all the details should be carried out in " decency and in order," and with a minimum amount of suffering to the culprit, and from this stand-point I shall treat the subject. The mode of carrying out the sentence of the law, " be hanged by the neck until you are dead," has usually been left to the discretion of the hangman, the law taking no cognizance as to what is to be the proximate cause of death. Calcraft invariably adopted the short drop of about two feet and a half ; and if I may judge from some speci- mens of his ropes, which are still to be seen at Kirkdale, death must have been produced by a slow process of asphyxia. Marwood adopted what is generally known as the long drop, of which he was supposed by many to be the originator, though it was used long before his time, both in Paris and in Ireland. To Professor Haughlon we are indebted for a scientific exposition * of the rationale of the long drop, and of the mode in which death takes place. Dr. Haughton also gives an elaborate explanation of the American method, which is a scientific modification of the old naval method of running the culprit up to the yard-arm. Having now briefly referred to the different modes of hanging which have been adopted in executing criminals, we will be better able to judge which is the best and most practical method when we have considered the various causes of death. Professor Tidy f says that " in hanging, as in drowning, death does not always take place in exactly the same way. Thus, it may result from — (1) asphyxia ; (2) cerebral hyperemia ; (3) a combination of asphyxia with apoplexy ; (4) syncope ; (5) injury to the spinal cord and pneumogastrics (neuro- paralytic death)." Professor Hoffmann, \ of Vienna, says that, " in hanging, the noose does not press directly on the larynx and the trachea, but almost al- ways slips between the larynx and. the chin. In these cases the basis of the tongue is pushed upward, and pressed against the posterior wall * " Principles of Animal Mechanics," 18*73. f " Legal Medicine," part ii, p. 385. % "British Medical Journal," December 21, 1878, and May 10, 1879. 5°4 THE POPULAR SCIENCE MONTHLY. of the pharynx, completely closing it. The most important agent, however, in this kind of death is the compression of the larger vessels and the cervical portion of the vagus nerve, the upper portion of the carotid being pressed against the transverse processes of the cervical vertebrae before it branches off into the external and internal carotids, and the inner coat of the vessel being ruptured. The jugular veins are compressed at the same time, and the brain can neither receive any more blood nor allow that which it contains already to flow away ; its irritability is therefore extinct. The very important part which both the vagus and the vessels take in causing death by hanging is clearly shown through the following observations : 1. Loss of consciousness following immediately the compression caused by the rope at the moment when the noose is drawn tight by the weight of the body. The truth of this assertion is proved by the fact that no person who commits suicide by hanging ever attempts to rid himself of the rope which throttles him, although he might do so easily by standing up- right, as the body is not always suspended above the surface of the ground. 2. The rapidity with which death ensues and the beating of the heart stops. The few struggling respirations which generally occur in asphyxia shortly before death have not been observed in per- sons who have been hung. It is also well known how difficult it is to restore such patients to life. Death by hanging is, then, complex. It results from the occlusion of the respiratory tubes, from the sudden interruption of the passage of blood into the brain, and possibly from arrest of the circulation determined by the compression of the vagi nerves." These observations of Professor Hoffmann obviously refer to cases of constriction of the neck without dislocation of the vertebras, and show how death should take place rather than how it does in cases of the short drop. The constriction of the neck is not usually so complete as he has assumed ; the carotids are not completely oblit- erated, as shown by the pulse in the temporal artery, and by the grad- ual increasing congestion of the head — owing to the obstruction to the venous return — until at last the tongue is protruded out of the mouth ; nor is the vagus much pressed upon, as evidenced by the long continuance of the heart's beats in manv cases. It shows rather a paucity of reasoning to infer immediate loss of consciousness because no suicide " ever attempts to rid himself of the rope which throttles him." A suicide is a very unlikely individual to change his purpose during the short period which elapses between suspension and loss of consciousness. Dr. Taylor * states that " death from hanging appears to take place very rapidly, and without causing any suffering to the person. Pro- fessor Tidy, also, speaks of the painless nature of death from hang- ing ; while Professor Haughton, in his paper read before the Surgical Society of Dublin, says that " the old system of taking a convict's life * "The Principles and Practice of Medical Jurisprudence," 1865, p. 651. THE MECHANICS OF HANGING. 505 by suffocation is inhumanly painful, unnecessarily prolonged, and revolting to those whose duty it is to be present." Those who speak of the painless nature of death by strangulation arrive at this conclu- sion from the fact that many cases of suicide are not completely sus- pended, and that if they wished they could easily relieve the constric- tion by assuming the erect posture, and in other cases of recovery from attempted suicide by hanging there is no recollection of any suffering. It should be remembered, however, that there is a great difference between the mental attitude of the suicide and one who is about to suffer the extreme penalty of the law. In the former case he is regardless, and perhaps also not very sensitive, of a little suffer- ing, while in the latter every nerve is braced up to resist the inevitable result. Moreover, in those cases of recovery the loss of recollection of suffering does not prove that there was none. It might almost as well be said that, because in many cases of recovery from meningitis there was no remembrance of any suffering, therefore there was none. No doubt, the pain in hanging can under no circumstances be very acute, yet when we see a culprit heaving his chest and almost raising the whole body in his struggles for breath we must conclude that there is at least a considerable amount of mental torture. While death from asphyxia as ordinarily brought about by the short drop is a barbarism which should not be tolerated in this humani- tarian age, yet it might be accomplished without much suffering. If this mode of death be determined upon, then the constriction should be complete, and the compression of the blood-vessels, both veins and arteries, and if possible also the nerves, is of even more importance in the production of rapid unconsciousness than the occlusion of the windpipe. In accomplishing this object the position of the noose is of importance ; it should never be placed over the larynx, as the rigidity of that organ prevents complete compression and also shields the blood-vessels. Below the larynx would perhaps be the best position, but then there would always be the danger of the noose shifting up to the least desirable spot, therefore the most suitable position would seem to be between the hyoid bone and lower jaw. The rope should be thin and pliable, and not very elastic (a silk rope would perhaps be the best), the ring should be placed under the lower jaw, and the drop should be long enough to compress windpipe, blood-vessels, and nerves. If a half -inch silk rope were used I should think a drop of from four to six feet, according to the weight of the prisoner, would be sufficient. As to deaths from cerebral hyperemia, and its combination with as- phyxia, they are merely modifications of the latter form of death, and result from incomplete constriction, the windpipe not being quite oc- cluded, while the venous return is obstructed, but not the arterial supply. They are thus rather slow forms of death, and consequently not desirable. Death from syncope may be associated with any mode of hanging, but is perhaps most frequently connected with the long 5o6 THE POPULAR SCIENCE MONTHLY. drop. It is about the most rapid and least painful, though perhaps the rarest form of death. In a case of syncope, I have seen the heart's action cease in two minutes from the time the bolt was drawn. Fear largely contributes to this mode of death. It now remains for us to consider death by dislocation or fracture of the cervical vertebra?, with consequent laceration of the spinal cord. It is frequently supposed that the injury arises from rupture of the transverse ligament of the atlas and pressure on the cord by the odon- toid process, but, if ever this does occur, it must be extremely rare. Rupture of the transverse ligament could only take place when the rope was adjusted very high in the neck, with the ring directly in front or behind. And even then the odontoid process would be more likely to break than the ligament. The destructive effect occurs at the point on which the strain is brought to bear, and so the seat of injury varies in different cases. I have seen it take place in the fol- lowing situations : Complete separation between the second and third cervical vertebras and fracture of the odontoid process at its junction with the body of the axis ; oblique fracture through the body of the axis, leaving the upper fragment with attached odontoid process in situ, and fracture of the arch separating it from the body of the axis ; complete separation between the second and third cervical vertebras above the intervertebral disk, also slight separation and tearing of ligaments between the atlas and the axis ; and complete dislocation between the fifth and sixth cervical vertebras. In this latter case the ring hitched on the chin, and the opposite part of the noose was low in the neck, so that the long leverage action determined the low posi- tion of the injury. In every case the vertebras were separated at the point of injury for at least an inch, the spinal cord was severed, and the vertebral arteries and all the ligaments were torn across. The shock to the nervous system produces an immediate loss of consciousness, with complete paralysis of all the voluntary muscles. It takes a body moving under the influence of gravity three quarters of a second to fall through the space of nine feet ; and, owing to the velocity acquired, according to the law of uniformly accelerated mo- tion, the time occupied in the last seven inches — during which the stretching and tightening of the rope occurs — is only '0225 of a sec- ond. If to this we add, say, "0275 for the elasticity of the rope, then the whole time during which the shock could be felt is only *05, or one twentieth of a second. Even from this we must deduct the time which it takes for the nervous impression to travel to the sensorium and back, but, as the nerve-current travels at the rate of one hundred feet per second, this is so slight that, like the atmospheric resistance to the falling body, it may be left out of account. Although loss of consciousness, and it is with this that humanitarians are chiefly con- cerned, is instantaneous, yet death, as evidenced by the cessation of the heart's action, does not take place so rapidly. It is possible in THE MECHANICS OF HANGING. 507 some cases that the cardio-inhibitory center may be stimulated, or the vagi compressed, so as to immediately arrest the beat of the heart, yet I am convinced that this is the exception, and not the rule. The respiratory and vaso-motor centers are at once paralyzed. I have never seen even the faintest involuntary gasp, and the arteries feel at once to have lost tone. The excito-motor ganglia of the heart keep up its action, in the majority of cases, for some minutes independently of the central nervous system, and its arrest is probably brought about by a process of asphyxia. The immediate cessation of all respir- atory movements deprives the heart of all assistance in carrying on the circulation, and prevents the lungs from becoming surcharged with blood, as in ordinary cases of asphyxia, but the other signs of death from that cause are usually present, such as turgescence of the right side of the heart and general venous system ; great lividity of the face ; swelling, and perhaps protrusion, of the tongue. It should be remembered that these latter signs are best observed during sus- pension, because when the body is taken down hypostasis occurs quickly owing to the great fluidity of the blood, the tongue recedes within the mouth, and the general lividity on the upper surface of the body disappears, to reappear in the most dependent parts. The right side of the heart soon becomes incapable of driving the unoxi- dized blood through the lungs ; the left ventricle at first readily pro- pels the blood into the lax arteries, but soon the supply is diminished and the contraction becomes feeble, and at the same time the blood is accumulating in the venous system, and thus tending to equalize the pressure, and so at last the left ventricle is unable to drive its modicum of blood through the systemic capillaries. We have thus at the same time both sides of the heart unable to perform their work, and cessa- tion of the cardiac action is the result. The time during which I have observed the heart's action after dislocation of the cervical vertebras has ranged from two to thirteen minutes. As Professor Haughton has shown, the destructive effect on the neck of the criminal is in pro- portion to the vis viva which is acquired by the weight of the culprit and length of the drop ; and, if the drop be long enough, the vertebras are certain to be dislocated, no matter what be the position of the ring or thickness of the rope. The vis viva in any case is equivalent to half the mass multiplied by the square of the terminal velocity. Let W represent the weight of the criminal, and S the length of the drop, then the formula will be : 1 1 W -MV8 = ^26S = WS, ii VT til or the weight of the criminal multiplied by the length of the drop expresses in foot-pounds the amount of work expended on the neck of the criminal. I have not complicated the formula with the co-efficient of the elasticity of the rope — which is very slight — as we will devote some attention to the character of the rope further on. I would now 5o8 THE POPULAR SCIENCE MONTHLY. modify Dr. Haughton's rules by substituting, say, 1,260 foot-pounds for 2,240. If the neck of the criminal be small and delicate, or the rope very fine, then it would be well to calculate on a lower basis — say, 1,120 foot-pounds. Thus, a man weighing 140 pounds would require a drop of nine feet (1,260 -J- 140 = 9), and one weighing 120 pounds should have ten feet and a half (1,260 ~ 120 = 10|). The rope should not be too thick nor too elastic, otherwise the abrupt shock will be broken, and the advantages of the long drop lost ; but, on the other hand, it should not be too thin nor too inelastic, as then there is not merely the risk of the rope breaking, but also of snapping the head off the culprit. The rope should be of the finest and best hemp, pliable, and capable of bearing a strain of at least a ton and a half. About three fourths to seven eighths of an inch in diameter will be found a convenient thickness, and every rope should be tested before being used. I have been told by the master of a ship that, if in the manufacture of the rope the hemp be run through oil, it makes the rope much more pliable. It would certainly prevent it from be- coming stiff when exposed during a wet morning. The iron hooks and couplings to which the rope is attached should be inspected on each occasion. There has been a great difference of opinion regarding the position of the ring ; Professor Haughton recommends that it be placed under the chin, while Dr. Barker, of Melbourne, would have it on the nape of the neck. When the ring is placed in the latter position, the chin naturally falls forward on the sternum, and the rope has no leverage action whatever to assist in dislocation ; and, moreover, the noose does not tighten well on the neck, but the ring lies against the occi- put ; so this position is not only the worst for producing luxation, but also for strangulation. When the ring is under the jaw or chin there is a leverage of several inches, the head is thrown back or to one side, and the noose firmly constricts the neck. In the stretching of the rope the noose tightens several inches ; if, therefore, the ring be placed under the angle of the lower jaw on either side, and directed forward, it will be drawn under the chin in the act of tightening. The noose should be placed as high in the neck as possible, and drawn just suf- ficiently tight to prevent it slipping out of position while the body is falling. If those in authority would lay down a few simple rules as to the manner in which executions should be performed, then it would not require much science to carry them out. These rules might perhaps also have the effect of relegating the executioner more into obscurity, and dispel all illusionary ideas as to his being the possessor of a mystic craft, or one to be feted by the populace and interviewed by the press in order to satisfy a morbid public taste. — Lancet. DIET IN RELATION TO AGE AND ACTIVITY. 509 DIET IN RELATION TO AGE AND ACTIVITY. Br Sib HENKY THOMPSON. [Concluded.] ANOTHER agent in the combination to maintain for the man of advancing age his career of flesh-eater is the dentist. Nothing is more common at this period of life than to hear complaints of indi- gestion experienced, so it is affirmed, because mastication is imper- fectly performed for want of teeth. The dentist deftly repairs the defective implements, and the important function of chewing the food can be henceforth performed w7ith comfort. But, without any intention to justify a doctrine of final causes, I would point out the significant fact that the disappearance of the masticating powers is mostly coincident with the period of life when that species of food which most requires their action — viz., solid animal fiber — is little, if at all, required by the individual. It is during the latter third of his career that the softer and lighter foods, such as well-cooked cereals, some light mixed animal and vegetable soups, and also fish, for which teeth are barely necessary, are particularly valuable and appropriate. And the man with imperfect teeth who conforms to Nature's demand for a mild, non-stimulating dietary in advanced years will mostly be blessed with a better digestion and sounder health than the man who, thanks to his artificial machinery, can eat and does eat as much flesh in quantity and variety as he did in the days of his youth. Far be it from me to undervalue the truly artistic achieve- ments of a clever and experienced dental surgeon, or the comfort which he affords. By all means let us have recourse to his aid when our natural teeth fail, for the purpose of vocal articulation, to say nothing of their relation to personal appearance : on such grounds the artificial substitutes rank among the necessaries of life in a civil- ized community. Only let it be understood that the chief end of teeth, so far as mastication is concerned, has in advancing age been to a great extent accomplished, and that they are now mainly useful for the purposes just named. But I can not help adding that there are some grounds for the belief that those who have throughout life from their earliest years consumed little or no flesh, but have lived on a diet chiefly or wholly vegetarian, will be found to have preserved their teeth longer than those who have always made flesh a prominent part of their daily food. Then there is that occasional visit to the tailor, who, tape in hand, announces in commercial monotone to the listening clerk the various measurements of our girth, and congratulates us on the gradual in- crease thereof. He never in his life saw you looking so well, and " fancy, sir, you are another inch below your armpits " — a good deal 5io THE POPULAR SCIENCE MONTHLY. below — " since last year ! " insidiously intimating that in another year or so you will have nearly as fine a chest as Heenan ! And you, poor deluded victim, are more than half willing to believe that your in- creasing size is an equivalent to increasing health and strength, espe- cially as your wife emphatically takes that view, and regards your augmenting portliness with approval. Ten years have now passed away since you were forty, and by weight twelve stone and a half — a fair proportion for your height and build. Now you turn the scale to one stone more, every ounce of which is fat ; extra weight to be carried through all the labors of life. If you continue your present dietary and habits, and live five or seven years more, the burden of fat will be doubled ; and that insinuating tailor will be still congratulating you. Meantime you are " running the race of life " — a figure of speech less appropriate to you at the present moment than it formerly was — handicapped by a weight which makes active movement difficult, up- stair ascents troublesome, respiration thick and panting. Not one man in fifty lives to a good old age in this condition. The typical man of eighty or ninety years, still retaining a respectable amount of energy of body and mind, is lean and spare, and lives on slender rations. Neither your heart nor your lungs can act easily and healthily, being oppressed by the gradually gathering fat around. And this because you continue to eat and drink as you did, or even more luxuriously than you did, when youth and activity disposed of that moiety of food which was consumed over and above what the body required for sustenance. Such is the import of that balance of unex- pended aliment which your tailor and your foolish friends admire, and the gradual disappearance of which, should you recover your senses and diminish it, they will still deplore, half frightening you back to your old habits again by saying, " You are growing thin : what can be the matter with you?" Insane and mischievous delusion ! It is interesting to observe that the principle I have thus endeav- ored to illustrate and support, little as it is in accordance with the pre- cept and practice of modern authority, was clearly enunciated so long ago as the sixteenth century. The writings of Luigi Cornaro, who was born of noble family in Venice soon after the middle of the fifteenth century, and was contemporary for seventy years with Titian, wrote his first essay on the subject of regimen and diet for the aged when eighty-three years of age, producing three others during the subse- quent twelve years.* His object was to show that, with increasing age and diminished powers, a corresponding decrease in the quantity * " Discorsi delta Vita Solria, del Signor Luigi Cornaro." An English edition, with translation, was published by Benjamin White, at Horace's Head, in Fleet Street, Lon- don, 1768. Cornaro's first work was published in Padua in 1658. In his last, a letter written to Barbaro, Patriarch of Aquileia, he gives a description of his health and vigor when ninety-five years old. A paper in the " Spectator " was one of the first notices of him in this country. See vol. iii, No. 195. DIET IN RELATION TO AGE AND ACTIVITY. 511 of food must be taken in order to preserve health. He died at Padua " without any agony, sitting in an elbow-chair, being above one hun- dred years old." Thus he writes : There are old lovers of feeding who say that it is necessary they should eat and drink a great deal to keep up their natural heat, which is constantly diminish- ing as they advance in years ; and that it is, therefore, their duty to eat heartily, and of such things as please their palate, be they hot, cold, or temperate ; and that, were they to lead a sober life, it would be a short one. To this I answer that our kind mother, Nature, in order that old men may live still to a greater age, has contrived matters so that they should be able to subsist on little, as I do, for large quantities of food can not be digested by old and feeble stomachs. ... By always eating little the stomach, not being much burdened, need not wait long to have an appetite. It is for this reason that dry bread relishes so well with me; and I know it from experience, and can with truth affirm, I find such sweetness in it that I should be afraid of sinning against temperance, were it not for my being convinced of the absolute necessity of eating of it, and that we can not make, use of a more natural food. And thou, kind parent Nature, who actest so lovingly by thy aged offspring, in order to prolong his days, hast contrived mattters so in his favor, that he can live upon very little; and, in order to add to the favor, and do him still greater service, hast made him sensi- ble, that as in his youth he used to eat twice a day, when he arrives at old age he ought to divide that food, of which he was accustomed before to make but two meals, into four; because, thus divided, it will be more easily digested; and, as in his youth he made but two collations in the day, he should, in his old age, make four, provided, however, he lessens the quantity as his years increase. And this is what I do, agreeably to my own experience ; and, therefore, my spirits, not oppressed by much food, but barely kept up, are always brisk, espe- cially after eating, so that I am obliged then to sing a song, and afterward to write. Nor do I ever find myself the worse for writing immediately after meals, nor is my understanding ever clearer, nor am I apt to be drowsy, the food I take being in too small a quantity to send up any fumes to the brain. Oh, how advantageous it is to an old man to eat but little 1 Accordingly I, who know it, eat but just enough to keep body and soul together. Cornaro ate of all kinds of food, animal as well as vegetable, but in very small quantity, and he drank moderately of the light wine of his country, diminishing his slender rations as age increased. I am quite aware that I am reciting a story which must be familiar to some of the readers of this review. But it is by no means widely known, and is too apt an example of the value of the law under consideration not to be referred to here. It must now be clearly understood, as a general rule for men at all ages, that the amount of food ingested ought to accord within certain narrow limits with the amount of force employed for the purposes of daily life. But there is a certain qualification, apparent but not real, of the principle thus enunciated which must be referred to here, in order to prevent misunderstanding or misinterpretation of my mean- 5i2 THE POPULAR SCIENCE MONTHLY. ing in relation to one particular. It is right and fitting that a certain amount of storage material, or balance, should exist as a reserve in the constitution of every healthy man. Every healthy individual, indeed, necessarily possesses a stored amount of force, which will stand him in good stead when a demand arises for prolonged unusual exertion, or when any period of enforced starvation occurs, as dur- ing a lingering fever or other exhausting disease. The existence of this natural and healthy amount of reserved force is of course pre- supposed throughout all my remarks, and its extreme value is taken for granted. That undue amount of stored nutriment, that balance which has been referred to as prejudicial to the individual, is a quan- tity over and above the natural reserve produced by high health ; for, when augmented beyond that point, the material takes the form of diseased deposit, and ceases to be an available source of nutriment. Even the natural amount of store or reserve is prone to exceed the necessary limit in those who are healthy or nearly so. Hence it is that in all systems of training for athletic exploits — which is sim- ply a process of acquiring the highest degree of health and strength attainable, in view of great or prolonged exertion — some loss of weight is almost invariably incurred in developing a perfect condi- tion. In other words, almost any man who sets himself to acquire by every means in his power the best health possible for his system does in the process necessary thereto throw off redundant materials, the presence of which is not consistent with the high standard of function required. Thus what is sometimes called " overtraining " is a condi- tion in which the storage is reduced too much, and some weakening is incurred thereby ; while " undertraining " implies that the useless fatty and other matters have not been sufficiently got rid of, so that the athlete is encumbered by unnecessary weight, and is liable to need- less embarrassments, telling against his chances in more ways than one. The exact and precise balance between the two conditions is the aim of the judicious trainer. We are thus led to the next important consideration, namely, that although broad rules or principles of diet may be enunciated as applicable to different classes of people in general, no accurate adap- tation to the individual is possible without a knowledge of his daily habits and life, as well as to some extent of his personal peculiarities. No man, for example, can tell another what he can or ought to eat, without knowing what are the habits of life and work — mental and bodily — of the person to be advised. Notwithstanding which, no kind of counsel is more frequently tendered in common conversation by one stranger with another, than that which concerns the choice of food and drink. The adviser feels himself warranted, by the experi- ence that some particular combination of nourishment suits his own stomach, to infer without hesitation that this dish will be therefore acceptable to the stomachs of all his neighbors. Surely the intelli- DIET IN RELATION TO AGE AND ACTIVITY. 513 gence of such a man is as slender as his audacity and presumption are large. It would not he more preposterous if, having with infinite pains obtained a last representing precisely the size and the peculiari- ties in form of his own foot, he forthwith solemnly adjured all other persons to adopt boots made upon that model, and on none other ! Only it may be assumed that there is probably more difference be- tween stomachs and their needs among different individuals than among the inferior extremities referred to for the purpose of illustra- tion. Thus, in regard of expenditure of food, how great is the dif- ference between that of a man who spends ten or twelve hours of the day at the work of a navvy, as an agricultural laborer in harvest- time, or in draining or trenching land, as a sawyer, a railway porter, or a bricklayer's laborer, or let me add that of an ardent sportsman, as compared with the expenditure of a clerk who is seated at the desk, of individuals engaged in literary and artistic pursuits, demand- ing a life mostly sedentary and spent in-doors, with no exercise but that which such persons voluntarily take as a homage to hygienic duty, and for a short period borrowed at some cost from engagements which claim most of their time and nearly all their energies ! While the manual laborers rarely consume more food than they expend, and are, if not injured by drink, or by undue exposure to the weather, mostly hale and hearty in consequence, the latter are often martyrs to continued minor ailments, which gradually increase, and make work difficult, and life dreary. Few people will believe how easy it is in most instances to meet the difficulty by adopting appro- priate food, and that such brain-workers can really enjoy a fair degree of health and comfort by living on light food, which does not require much force to digest, and much muscular activity to assimilate — a diet, moreover, which is important to some of these from another point of view — the financial one — inasmuch as it is at least less costly by one half than the conventional meals which habit or custom pre- scribes alike to large classes of men in varied conditions of life. But there is another and more important economic gain yet to be named, as realizable through the use of a light and simple dietary. It is manifested by the fact that a greater expenditure of nerve-power is demanded for the digestion of heavy meat meals than for the lighter repasts which are suitable to the sedentary ; from which fact it results of course that this precious power is reserved for more useful and more delightful pursuits than that of mere digestion, especially when this is not too well performed. But those who have little time for exercise, and are compelled to live chiefly within-doors, must endeavor to secure, or should have se- cured for them as far as possible by employers, by way of compensa- tion, a regular supply of fresh air without draughts, an atmosphere as free from dust and other impurities as can be obtained, with a good supply of light, and some artificial warmth when needed. These ne- void xxtii. — 33 5 14 THE POPULAR SCIENCE MONTHLY. cessities granted, cereal foods, such as well-made bread in variety, and vegetable produce, including fruits, should form a great part of the diet consumed, with a fair addition of eggs and milk if no meat is taken, and little of other animal food than fish. On such a dietary, and without alcoholic stimulants, thousands of such workers as I have briefly indicated may enjoy with very little exercise far better health and more strength than at present they experience on meat and heavy puddings, beer, baker's bread, and cheese. Of course there are workers who belong to neither of the two extreme classes indicated, and whose habits can not be described as sedentary, but who occupy a middle place between the two. For such, some corresponding modification of the dietary is naturally appropriate. But it is a vulgar error to regard meat in any form as necessary to life ; if for any it is necessary, it is for the hard-working out-door laborers above referred to, and for these a certain proportion is no doubt desirable. Animal flesh is useful also as a concentrated form of nutriment, valuable for its portability ; and, for the small space it occupies in the stomach, unrivaled in certain circumstances. Like every other description of food, it is highly useful in its place, but is by no means necessary for a large proportion of the population. To many it has become partially desirable only by the force of habit, and because their digestive organs have thus been trained to deal with it, and at first resent a change. But, this being gradually made, adaptation takes place, and the individual who has consumed two or three meat meals daily with some little discomfort, chiefly from being often indisposed to make active exertions, becomes, after sufficient time has elapsed, stronger, lighter, and happier, as well as better tempered, and manifestly healthier, on the more delicate dietary sketched. People in general have very inadequate ideas of the great power of habit alone in forming what they believe to be innate personal peculiarities, or in creating conditions which are ap- parently part of a constitutional necessity, laws of their nature and essential to their existence. Many of these peculiarities are solely due to habit, that is, to long continuance in a routine of action, adopted it may be without motive or design ; and people are apt to forget that, if a routine of a precisely opposite character had been adopted, precisely opposite conditions would have been established, and opposite pecul- iarities would have become dominant, as their contraries are now. Al- terations in the dietary, especially of elderly persons, should be made gradually and with caution. This condition fulfilled, a considerable change may be effected with satisfactory results, when circumstances render it necessary. To revert once more to the question of flesh-eat- ing, it should be remarked that it appears to be by no means a natural taste with the young. Few children like that part of the meal which consists of meat, but prefer the pudding, the fruit, the vegetables, if well dressed, which unhappily is not often the case. Many children manifest great repugnance to meat at first, and are coaxed and even DIET IN RELATION TO AGE AND ACTIVITY. 515 scolded by anxious mothers until the habit of eating it is acquired. Adopting the insular creed, which regards beef and mutton as neces- sary to health and strength, the mother often suffers from groundless forebodings about the future of a child who rejects flesh, and manifests what is regarded as an unfortunate partiality for bread and butter and pudding. Nevertheless, I am satisfied, if the children followed their own instinct in that matter, the result would be a gain in more ways than one. Certainly, if meat did not appear in the nursery until the children sent for it, it would be rarely seen there, and the young ones would as a rule thrive better on milk and eggs, with the varied produce of the vegetable kingdom. A brief allusion must be made to the well-known and obvious fact that the surrounding temperature influences the demand for food, which therefore should be determined as regards quantity or kind according to the climate inhabited, or the season of the year as it affects each climate. In hot weather, the dietary should be lighter, in the under- stood sense of the term, than in cold weather. The sultry period of our summer, although comparatively slight and of short duration, is nevertheless felt by some persons to be extremely oppressive ; but this is mainly due to the practice of eating much animal food or fatty mat- ters, conjoined as it often is with the habit of drinking freely of fluids containing a small quantity of alcohol. Living on cereals, vegetables, and fruits, with some proportion of fish, and abstaining from alcoholic drinks, the same person would probably enjoy the high temperature, and be free from the thirst which is the natural result of consuming needlessly substantial and heating food. There is a very common term, familiar by daily use, conveying un- mistakably to every one painful impressions regarding those who mani- fest the discomforts indicated by it — I mean the term indigestion. The first sign of what is so called may appear even in childhood ; not being the consequence of any stomach disorder, but solely of some error in diet, mostly the result of eating too freely of rich compounds in which sugar and fatty matters are largely present. These elements would not be objectionable if they formed part of a regular meal, instead of being consumed as they mostly are between meals, already abounding in every necessary constituent. Sugar and fat are elements of value in children's food, and natu- rally form a considerable portion of it, entering largely into the com- position of milk, which Nature supplies for the young and growing animal. The indigestion of the child mostly terminates rapidly by ejection of the offending matter. But the indigestion of the adult is less acutely felt and is less readily disposed of. Uneasiness and inca- pacity for action, persisting for some time after an ordinary meal, indicate that the stomach is acting imperfectly on the materials which have been put into it. These signs manifest themselves frequently, and, if Nature's hints that the food is inappropriate are not taken, they 516 THE POPULAR SCIENCE MONTHLY. become more serious. Temporary relief is easily obtained by medi- cine ; but if the unfortunate individual continues to blame his stom- ach, and not the dietary he selects, the chances are that his troubles will continue, or appear in some other form. At length, if unenlight- ened on the subject, he becomes " a martyr to indigestion," and resigns himself to the unhappy fate, as he terms it, of " the confirmed dys- peptic." Such a victim may perhaps be surprised to learn that nine out of ten persons so affected are probably not the subjects of any complaint whatever, and that the stomach at any rate is by no means necessarily faulty in its action — in short, that what is popularly termed " indiges- tion " is rarely a disease in any sense of the word, but merely the nat- ural result of errors in diet. For most men it is the penalty of conformity to the eating habits of the majority ; and a want of dis- position or of enterprise to undertake a trial of simpler foods than those around them consume probably determines the continuance of their unhappy troubles. In many instances it must be confessed that the complaint, if so it must be called, results from error, not in the quality of the food taken, but in the quantity. Eating is an agreeable process for most people, and under the influence of very small temp- tation, or through undue variety furnishing a source of provocation to the palate, a considerable proportion of nutritious material above what is required by the system is apt to be swallowed. Then it is also to be remembered that stomachs which vary greatly in their capacity and power to digest may all nevertheless be equally healthy and competent to exercise every necessary function. In like manner we know that human brains which are equally sound and healthy often differ vastly in power and in activity. Thus a stomach, which would be slandered by a charge of incompetence to perform easily all that it is in duty bound to accomplish, may be completely incapable of digesting a small excess beyond that natural limit. Hence, with such an organ an indigestion is inevitable when this limit is only slightly exceeded. And so when temptations are considerable, and frequently complied with, the disturbance may be, as it is with some, very serious in degree. How very powerful a human stomach may sometimes be, and how large a task in the way of digestion it may sometimes perform without complaint, is known to those who have had the opportunity of observing what certain persons with excep- tional power are accustomed to take as food, and do take for a long time apparently with impunity. But these are stomachs endowed with extraordinary energy, and woe be to the individual with a digest- ive apparatus of moderate power who attempts to emulate the per- formance of a neighbor at table who perchance may be furnished with such an effective digestive apparatus ! But, after all, let not the weaker man grieve overmuch at the un- even lot which the gods seem to have provided for mortals here below DIET IN RELATION TO AGE AND ACTIVITY. 517 in regard of this function of digestion. There is a compensation for him which he has not considered, or perhaps even heard of, although he is so moderately endowed with peptic force. A delicate stomach which can just do needful work for the system and no more, by neces- sity performs the function of a careful door porter at the entrance of the system, and like a jealous guardian inspects with discernment all who aspire to enter the interior, rejecting the unfit and the un- bidden, and all the common herd. On the other hand, a stomach with superfluous power, of whom its master boastfully declaims that it can " digest tenpenny nails," and that he is unaccustomed to consult its likes and its dislikes if it have any, is like a careless hall porter who admits all comers, every pre- tender, and among the motley visitors many whose presence is damag- ing to the interior. These powerful feeders after a time suffer from the unexpended surplus, and pay for their hardy temerity in becoming amenable to penalty, often suddenly declared by the onset of some serious attack, demanding complete change in regimen, a condition more or less grave. On the other hand, the owner of the delicate stomach, a man perhaps with a habit of frequently complaining of slight troubles, and always careful, will probably in the race of life, as regards the preceding pilgrim, take the place of the tortoise as against the hare. It is an old proverb that " the creaking wheel lasts longest," and one that is certainly true as regards a not powerful but nevertheless healthy stomach which is carefully treated by its owner ; to whom this fact may be acceptable as a small consolation for the possession of a delicate organ. For it is a kind of stomach which not seldom accompanies a fine organization. The difference is central, not local — a difference in the nervous system chiefly ; the impressionable mental structure, the in- strument of strong emotions, must necessarily be allied with a stomach to which the supply of nerve-power for digestion is sometimes tempo- rarily deficient and always perhaps capricious. There are more sources than one of compensation to the owner of an active, impressionable brain, with a susceptible stomach possessing only moderate digestive capabilities— sources altogether beyond the imagination of many a coarse feeder and capable digester. But it is not correct, and it is on all grounds undesirable, to regard the less powerful man as a sufferer from indigestion, that is, as liable to any complaint to be so termed. True indigestion, as a manifestation of a diseased stomach, is comparatively quite rare, and I have not one word to say of it here, which would not be the fitting place if I had. Not one person in a hundred who complains of indigestion has any morbid affection of the organs engaged in assimilating his food. As commonly employed, the word " indigestion " denotes, not a disease, but an admonition. It means that the individual so complaining has not yet found his appropriate diet ; that he takes food unsuited for 5i8 THE POPULAR SCIENCE MONTHLY. him, or too much of it. The food may be " wholesome enough in itself," a popular phrase permitted to appear here, first, because it conveys a meaning perceived by every one, although the idea is loosely expressed ; but, secondly and chiefly, for the purpose of pointing out the fallacy which underlies it. There is no food " wholesome in it- self," and there is no fact which people in general are more slow to comprehend. That food only is wholesome which is so to the individ- ual, and no food can be wholesome to any given number of persons. Milk, for example, may agree admirably with me, and may as certainly invariably provoke an indigestion from my neighbor ; and the same may be said of almost every article of our ordinary dietary. The wholesomeness of a food consists solely in its adaptability to the indi- vidual, and this relation is governed mainly by the influences of his age, activity, surroundings and temperament or personal peculiarities. Indigestion, therefore, does not necessarily, or indeed often, require medicine for its removal. Drugs, and especially small portions of alcoholic spirit, are often used for the purpose of stimulating the stomach temporarily to perform a larger share of work than by nature it is qualified to undertake ; a course which is disadvantageous for the individual if persisted in. The effect on the stomach is that of the spur on the horse : it accelerates the pace, but " it takes it out " of the animal, and, if the practice is long continued, shortens his natural term of efficiency. It is an erroneous idea that a simple form of dietary, such as the vegetable kingdom in the largest sense of the term furnishes, in con- junction with a moderate proportion of the most easily digested forms of animal food, may not be appetizing and agreeable to the palate. On the contrary, I am prepared to maintain that it may be easily served in forms highly attractive, not only to the general but to a cultivated taste. A preference for the high flavors and stimulating scents peculiar to the flesh of vertebrate animals mostly subsides after a fair trial of milder foods when supplied in variety. And it is an ex- perience almost universally avowed, that the desire for food is keener, that the satisfaction in gratifying appetite is greater and more enjoy- able, on the part of the general light feeder than with the almost exclusively flesh-feeder. For this designation is applicable to almost all those who compose the middle-class population of this country. They consume little bread and few vegetables ; all the savory dishes are of flesh, with decoctions of flesh alone for soup. The sweets are compounds of suet, lard, butter, eggs and milk, with very small quan- tities of flour, rice, arrowroot, etc., which comprise all the vegetable constituents besides some fruit and sugar. Three fourths at least of the nutrient matters consumed are from the animal kingdom. A re- versal of the proportions named, that is, a fourth only from the latter source with three fourths of vegetable produce, would furnish greater variety for the table, tend to maintain a cleaner palate, increased zest DIET IN RELATION TO AGE AND ACTIVITY. 519 for food, a lighter and more active brain, and a better state of health for most people not engaged on the most laborious employments of active life ; while even for the last named, with due choice of mate- rial, ample sustenance in the proportions named may be supplied. For some inactive, sedentary, and aged persons the small proportion of animal food indicated might be advantageously diminished. I am frequently told by individuals of sixty years and upward that they have no recollection of any previous period since reaching mature age at which they have possessed a keener relish for food than that which they enjoy at least once or twice a day since they have adopted the dietary thus described. Such appetite at all events as has rarely offered itself during years preceding, when the choice of food was con- ventionally limited to the unvarying progression and array of mutton and beef, in joint, chop, and steak, arriving after a strong meat soup, with a possible interlude of fish, and followed by puddings of which the ingredients are chiefly derived from animal sources. The pene- trating odors of meat cookery which announce their presence by escape from the kitchen, and will pervade the air of other rooms in any pri- vate house but a large one, and which are encountered in clubs, restau- rants, and hotels without stint, alone suffice to blunt the inclination for food of one who, returning from daily occupation, fatigued and fastidious, desires food easy of digestion, attractive in appearance, and unassociated with any element of a repulsive character. The light feeder knows nothing of the annoyances described, finds on his table that which is delightful to a palate sensitive to mild impressions, and indisposed to gross and over-powerful ones. After the meal is over, his wit is fresher, his temper more cheerful, and he takes his easy- chair to enjoy fireside talk, and not to sink into a heavy slumber, which on awakening is but exchanged for a sense of discontent or stupidity. The doctrine thus briefly and inadequately expounded in this j>aper may probably encounter some opposition and adverse criticism. I am quite content that this should be so. Every proposal which disturbs the current habits of the time, especially when based on long-prevalent custom, infallibly encounters that fate. But of the general truth, and hence of the ultimate reception of the principles I have endeavored to illustrate, there can not be the faintest doubt. And I know that this result, whenever it may be accomplished, will largely diminish the painful affections which unhappily so often appear during the latter moiety of adult life. And having during the last few years widely inculcated such general dietetic principles and practice, with abundant grounds for my growing conviction of their value, it appears to be a duty to call attention to them somewhat more emphatically than in preceding contributions already referred to. In so doing I have ex- pressly limited myself to statements relating to those simple element- ary facts concerning our every-day life which ought to be within the 520 THE POPULAR SCIENCE MONTHLY. knowledge of every man, and therefore such as may most fitly be set forth in a publication outside of that field of special and technical record which is devoted to professional observation and experience. — Nineteenth Century. ♦ «» BUILDING AND ORNAMENTAL STONES OF THE UNITED STATES. Br GEORGE P. MEEEILL. WHEN, early in his curatorship in the National Museum, Dr. George W. Hawes, one of the leading American lithologists, assumed charge of that branch of the tenth census relating to the quarrying industry of the United States, it is doubtful if any but himself fully realized the importance of the undertaking aside from its statistical bearings. Dr. Hawes was, however, not a man to be satisfied with fig- ures alone, or one who considered the scope of a census to be merely the compilation of statistics, and in selecting his assistants he did so with especial reference to their qualifications in other lines of work as well. Thus we find upon his list the names of such geologists as Professors Shaler and Wolff, of Harvard ; Hitchcock, of Dartmouth ; Winchell, of Minneapolis ; and others of equal note and ability. These assistants, or special agents as they were called, visited each quarry in person within their respective districts, and, together with collecting the -necessary information relative to the amount, kind, and value of stone quarried, number of men employed, etc., made all possible observations in regard to the geological age of the stone, its disposition in the quarry, weather- ing qualities as displayed in those portions of the outcrop that had been exposed for ages to the action of atmospheric agencies, and, lastly, selected samples of the rock in the form of blocks of sufficient size to dress into four-inch cubes and forwarded them bv mail to the National Museum, at Washington, for further examination.* Here a corps of assistants was employed who selected samples for chemical and micro- scopic analysis, and left the block to be handsomely dressed into a four-inch cube and placed permanently upon exhibition, having mean- while made careful notes upon its working qualities. Small chips of each rock were ground into films so thin as to be perfectly transparent, and submitted to microscopic examination in order not only to deter- mine what the rock was, but also to ascertain if it contained any min- eral constituents liable to unfavorable change on exposure to the weather. Whenever necessary, chemical analysis was resorted to to further aid in the solution of the problems involved. * These blocks weighed from six to ten pounds each, but, being Government matter, were allowed to pass through the mails, though greatly exceeding in weight the limit set by law. BUILDING AND ORNAMENTAL STONES. 521 Unfortunately, Dr. Hawes did not live to carry out the plans he had so carefully laid down, hut the vast amount of material he had been instrumental in bringing together remains to-day in the National Museum, a lasting monument to the industry of the man, and probably the most systematic and complete collection of its kind in any museum in the world. As now being arranged in the museum, the collection comprises some four thousand specimens of building and ornamental stone from upward of fifteen hundred quarries in the United States, together with very many from foreign localities. The importance of such a collection can not be overestimated. Here, within the space of an hour, one can see and examine every variety of stone now quarried, and ascertain its scientific name and chemical or mineral composition, together with the exact locality whence it was derived. That such a reference collection will prove of great advantage to the country at large is evident from the fact that New England granites have been used in nearly every city of impor- tance from Maine to California, sometimes to the almost entire exclu- sion of equally good material close at hand, but of whose existence or valuable qualities interested parties were ignorant. As an illustration of this, it may be stated that many of the public and private buildings of Cincinnati, Ohio, are built of Eastern granite brought by rail and water a distance of over fifteen hundred miles, while within one tenth that distance lie rocks in every respect equally good for the purpose, and that could be furnished at far less cost ! From the published report of the census as it now appears, there were quarried during the year ending May 31, 1880, 115,380,113 cubic feet of building and orna- mental stones, valued in the rough at $18,365,055 ; this being the prod- uct of 1,525 quarries representing an invested capital of $25,414,497, and affording employment during the busy season to upward of 40,000 men. The kinds of stone quarried are principally granites, limestones (including dolomite), sandstone, and slates. In value of total product, regardless of kinds, the leading States rank as follows : Ohio, Pennsylvania, Vermont, Massachusetts, Illinois, New York, Maine, and Connecticut, each of these producing upward of $1,000,000 worth of material. Massachusetts and Maine produce the most granite ; Ohio, New York, Pennsylvania, and Connecticut the most sandstone ; Ver- mont, Illinois, Ohio, and New York the most limestone, while Penn- sylvania leads in the production of slate. The larger portion of our granites are some shade of gray in color, though pink and red varieties are not uncommon. They vary in text- ure from very fine and homogeneous to coarsely porphyritic rocks in which the individual grains are an inch or more in length. The largest woi'ks at present in operation are at Vinalhaven, Maine. The quarries of the Bodwell Granite Company were first opened here in 1850, and the present annual product is some 217,000 cubic feet, val- ued at $112,000. The capabilities of these quarries may behest illus- 522 THE POPULAR SCIENCE MONTHLY. trated by stating that during a visit to the locality in the summer of 1883 the writer was shown the remains of a huge block of granite three hundred feet long, twenty feet wide, and from six to ten feet thick, that had been blown out from the quarry in a single piece and afterward broken up. The largest single block ever quarried and dressed was the General Wool Monument now in Troy, New York, which measured, when completed, sixty feet in height by five and a half feet square at the base, or only nine feet shorter than the Egyptian Obelisk now in Central Park, New York. The stone is light gray, often slightly pinkish in color, and corresponds closely with that from the now abandoned quarries on Dix Island, whence were taken the granite monoliths, thirty-one feet in height, for the Treasury Building at Washington. Second only to the quarries at Vinalhaven are those at Gloucester, Massachusetts — the quarries of the Cape Ann Granite Company. This rock is coarser in texture than that of Vinal- haven, and often of a slight greenish color. The new Masonic Tem- ple at Philadelphia, and the Butler House, on Capitol Hill, Washing- ton, are good illustrations of the adaptability of this stone for gen- eral building purjwses. Closely resembling the Cape Ann granite is that quarried at Quincy in the same State. Quarries were first regularly opened here in 1803, though it was from bowlders of this rock that was built in 1749-'54 King's Chapel, still standing on the corner of School and Tremont Streets, Boston. Quincy granite also was used in the construction of the Bunker Hill Monument, and it was for the transportation of this stone from the quarries to Charlestown that was built the first railway in America. The color of the stone is deep blue gray, and its fitness for interior decorative work is well shown in the granite stairways and polished pilasters of the new City Buildings in Philadelphia. For columns, house-trimmings, and especially monumental work, the granite from Hallowell, Maine, is used most extensively. This rock is of fine and even grain, and very light gray, almost white in color. Its texture is such that it can be carved very readily, and it has been used in statuary work more than any other of our granites. The statues on the Pilgrim Monument, at Plymouth, Massachusetts, are of this stone. An Italian designer, who served his apprenticeship in Roman studios, is employed by this company, and many of the workmen at the quarries are said to be Italians who worked in marble in Italy, but have learned to cut granite since their arrival at Hal- lowell. A granite, closely resembling that of Hallowell, is quarried very extensively near Concord, New Hampshire, and is used for similar pur- poses. Stones similar to these, but not at present in the market, are found near Frederickton, Virginia, and Atlanta, Georgia. The red and pink granites now in the market are nearly all from Calais and Jonesboro, in the eastern part of Maine, though others are BUILDING AND ORNAMENTAL STONES. 523 quarried at Mount Desert, in the same State ; Lyme and Stony Creek, Connecticut ; Westerly, Rhode Island ; and Graniteville, Missouri. The Calais rock, which is at present the most important of these, is a light pink in color, of medium coarseness of texture, and acquires beautiful surface and polish. It is used extensively for door-posts and the bases of monuments in all our principal cities, competing favorably with the coarser red granite from Peterhead, Scotland, or that from St. George, New Brunswick. Black granites are quarried in but two, and these widely separated, localities — St. George, Maine, and Penryn, California. Both stones are fine-grained, and nearly black on a polished surface, their dark colors being due to the abundance of black mica and hornblende that they contain. The greater part of the rock quarried and put upon the market under this name is, however, not granite at all, but diabase, a rock differing from granite in containing neither quartz, orthoclase, nor mica, but composed mainly of a triclinic feldspar and augite. The principal quarries of this rock are at Addison, Maine ; Medford and Somerville, Massachusetts ; York, Pennsylvania ; and near Jersey City, New Jersey. These rocks are all fine-grained and hard, and of a dark-gray color, that from Addison being nearly black when polished. The colors are rather too somber for general building purposes, but, when properly combined with brick or lighter stone, the effect is admirable. The Addison rock is being used to a considerable extent for cemetery and other monumental work, for which it seems peculiarly adapted, and together with the York diabase has been used in the stone- work of the Capitol-grounds at Washington. Diabase from the near vicinity has been used in the construction of the Stevens Institute building at Ho- boken, New Jersey, and the court-house and St. Patrick's Cathedral at Jersey City. The fronts of many private and business houses in the last-named city are also of diabase, but the effect is not good, owing to the somber colors already alluded to. From the fact that Maine and Massachusetts lead in the granite- quarrying industry, it does not necessarily follow that these States pro- duce a greater variety or better quality of material than some others in which the annual product is far less. The supremacy is due rather to natural quarrying and transportation facilities. In Maine especial- ly many of the quarries are situated on hill-sides close by the water's edge, where no artificial drainage is required, and but little carting of the stone is necessary prior to loading it upon vessels, by means of which transportation can be had to all the leading cities of the country without transhipment, an item of no small importance with material so bulky and heavy as stone. Added to this is the fact that the great glacial ice-sheet, that once plowed its way across the whole of New England, has entirely removed the overlying mass of decayed rock and other waste material, and left the fresh granite close to the sur- 5 24 THE POPULAR SCIENCE MONTHLY. face and readily accessible. In regions farther to the south, beyond the limits of glacial action, the granite-beds are still covered with a mass of decomposed rock, often many feet in thickness, and which must be removed before quarrying can commence. It is probably largely due to these facts that the granites of these two States are en- abled to compete so favorably in the Washington market with those from near Richmond, Virginia, a distance of only four or five hours' ride by rail. Granite did not come into general use for building purposes in this country until a comparatively recent date, owing largely to the great difficulty in working it. According to Mr. J. E. Wolff,* one of the earliest stone buildings in Boston was the " stone house of Deacon John Phillips," erected about 1650, and which continued to stand until 1864. It was built chiefly of bowlders from the immediate vicinity. In 1737 was built of bowlders, of Braintree (Quincy) granite, the old Hancock house, since torn down. The granite bowlders scattered over the commons had been very generally used in Quincy for steps, foun- dations, etc., for some years previous to this, until at last the inhabit- ants, becoming frightened lest this supply of valuable building mate- rial should become entirely exhausted, assembled in town-meeting and voted that "no person shall dig or carry off" any stone "on the said commons or undivided lands upon any account whatever without license from the committee, . . . upon penalty of the forfeiture of ten shil- lings for every and each cart-load so dug and carried away." Little did they then imagine that, close at their doors, this same stone ex- isted in such quantities that over half a century of almost constant quarrying has failed to exhaust the supply. It was not, however, until the early part of the present century that granite began to be used at all extensively in and about Boston, when the material was introduced in considerable quantities by canal from Chelmsford, thirty miles distant. It was from the Chelmsford stone that was constructed in 1810 the Boston Court-House, in 1814 the New South Church, and in 1818-'19 the first stone block in the city, a portion of which is still standing on Brattle Street. In this year also a considerable quantity of the stone was shipped to Savannah, Georgia, for the construction of a church at that place. The greater part of this granite was, how- ever, obtained from bowlders, and it was not until the opening of quarries at Quincy, in 1825, that the business assumed any great im- portance. From this time the use of granite for building material in- creased in a marked degree, and the history of stone-quarrying in Massachusetts may properly begin with this date. Under the head of marbles are here included all those rocks con- sisting essentially of carbonate of lime (limestone), or carbonate of lime and magnesia (magnesian limestones and dolomites), which are susceptible of receiving a good polish, and are suitable for orna- * " Building-Stone and Quarry Industry of the United States," p. 282. BUILDING AND ORNAMENTAL STONES. 525 mental work. Vermont is at present the chief marble - producing State of the Union, excelling in this industry all the other States com- bined, having an invested capital of $3,886,000, and producing annu- ally $1,340,050 worth of material. Of this the larger part is ordinary white, veined, or blue marble from Sutherland Falls, Rutland, East Dorset, and Pittsford. Dark gray, almost black fossiliferous marbles are, however, quarried at Isle La Motte, while red, mottled, and varie- gated varieties, used for tilings and wainscotings, are found at Mal- lett's Bay, in the northern part of Lake Champlain. The only statuary marble at present quarried in this country is found at West Rutland and Pittsford, in this State. The rock is of fine and even texture, and without specks or flaws, but differs from its Italian prototype in being of a dead-white color, lacking entirely the peculiar waxy luster so characteristic of the Italian marble. White and bluish marbles are also quarried at Lee, Massachusetts ; Sing Sing, Tuckahoe, and Pleas- antville, New York ; in Montgomery County, Pennsylvania ; and in Texas and Cockeysville, Maryland. The Montgomery County quarries were first opened upward of one hundred years ago, and until as late as 1840 the stone continued to be the general favorite in Philadelphia for all manner of building, although not well suited for the finer grades of ornamental work. Girard Col- lege, the United States Custom-House, Mint, and Naval Asylum, are of this stone, while the seemingly endless rows of red-brick houses, with white-marble sills and caps, have come to be as characteristic of Philadelphia as are the brown-stone fronts of New York. The colored marbles now in the market are brought principally from Tennessee. The ordinary red and white variegated varieties, so commonly seen in table-tops, mantels, soda-fountains, and panelings, are from Rogersville and Knoxville in this State. A fine grade of pink marble is also found at Cleaveland and Knoxville, while a fossil- bearing olive-green variety is brought from Calhoun. A peculiar brecciated stone, which I have not yet seen in the market, is also found here. It consists of yellowish, rounded, and angular fragments of varying sizes, imbedded in a fine, grayish ground-mass. So far as I have yet observed, this stone is entirely distinct from any produced elsewhere. Two fine varieties of gray fossiliferous marbles are pro- duced at Chazy and Plattsburg, in Clinton County, New York, and are known commercially as " Lepanto " and " French gray." The first- named is gray with pink spots, while the last-named is more uniformly gray in color. With the exception of the Tennessee marbles, the Plattsburg stone is more extensively used for furniture and inside decorative work than any other now in the market. The only first- quality black marble now produced in this country is also from New York State quarries at Glens Falls, furnishing a fine grade of this material. Other than in the States above mentioned no marbles of conse- 526 THE POPULAR SCIENCE MONTHLY. quence are now produced east of the Rocky Mountains, though several States are known to contain material that might be thus utilized if put upon the market. California, however, produces two varieties worthy of especial notice. The one is a white, finely crystalline stone, trav- ersed by a network of fine dark lines, in general appearance very much like the celebrated bardiglio marble from the Serravezza quarries, but that the ground-mass is lighter in color. The second variety is the beautiful stalagmite marble, or so-called onyx, from quarries at San Luis Obispo. This stone is pearly white in color, translucent, and traversed by fine, wavy, parallel lines, like the lines of growth upon the trunk of a tree. It takes a beautiful polish, and is quite extensively used for small stands and ornaments of various kinds. Excepting in the matter of color it is identical with the celebrated " Oriental alabas- ter" (wrongly so called), from Blad Recam, near the Ravine of Oned Abdallah, Egypt, this last being of a yellowish or amber hue. The San Luis Obispo rock is the only stalagmite marble of any commer- cial importance at present found in this country, though a beautiful variety, known as "Mexican onyx," is quarried at Tecali, State of Puebla, Mexico. In the way of true conglomerate or breccia marble there is at pres- ent nothing quarried, though a beautiful variety occurs in inexhaustible quantities near Frederickton, Maryland, and in other parts of this State and Pennsylvania. The stone consists of rounded and angular frag- ments, of varying colors and all sizes up to several inches in diameter, of quartz and limestone imbedded in a fine gray ground-mass. This admixture of hard and soft material renders the dressing of the stone a matter of great difficulty, since the flinty pebbles break away from the softer ground-mass in the process of cutting. The large pillars of the old House of Representatives in the Capitol at Washington are of this stone. The rock serpentine, though differing entirely from marble in chem- ical composition, is used for similar purposes, and may be mentioned here. The three principal sources of this rock, or of serpentine in combination with calcite, are Roxbury, Vermont ; Moriah, Essex Coun- ty, New York ; and Dublin, Harford County, Maryland. The Ver- mont stone is deep green in color, and traversed by white veins of calcite. It takes a beautiful polish, and compares very favorably with the Italian verde antique or verde di Prato from quarries in Tuscany. The Moriah stone is similar in color, but granular in text- ure, and spotted, rather than veined. At present it is found in the market in the form of mantels, table-tops, monuments, etc. The Maryland stone is more uniformly green in color than either of those mentioned above, containing very little calcareous matter. It is said to occur in almost inexhaustible quantities and within easy reach of the Baltimore market, but for some unexplained reason little, if any, of it is now in use. A coarse serpentine used for general building BUILDING AND ORNAMENTAL STONES. 527 purposes, but unsuited for any kind of ornamental work, is brought in considerable quantities from Chester County, Pennsylvania. The stone is dull-green in color, soft enough to work readily, and is capa- ble of producing most excellent effects, particularly in rock-faced and rubble work. So far as the writer has observed, however, it has not yet been used to advantage, either alone or in combination with other stone, a majority of the buildings thus far constructed of it being not only failures from an architectural stand-point, but showing a remark- able lack of taste in color combination on the part of their designers. A dull-green building with light, yellowish-gray trimmings can scarce- ly be considered a success artistically, yet this is the style almost universally adopted. The stone has been used quite extensively in and about Philadelphia, and is the one employed in the construction of the buildings of the University of Pennsylvania and Academy of Natural Sciences in that city. It has also been used to some extent in the cities of New York and Washington, though I have not yet observed it elsewhere. No marbles are at present quarried in this country similar to the white blue-veined Parmazo marble from the Miseglia quarries, like the red-veined from Levanto, like the yellow from Siena, the red " Griotte " from the French Pyrenees, or the black and gold (Portoro Venere) from the Spezia quarries. A stone somewhat resembling this last has been received at the museum from Helena, Montana, but the quarries are not worked, nor is the extent of the deposit known to the writer. A beauti- ful bright, flesh-pink marble occurs in abundance in Swain and Chero- kee Counties, North Carolina, but is not now in the market, owing to lack of transportation facilities. Of limestones and dolomites, aside from marbles, large quantities are quarried in the States of New York, Pennsylvania, Indiana, Illi- nois, Iowa, and Missouri. These are mostly of a dull-grayish, uninter- esting color, and their uses are chiefly local. The light-colored oolitic limestone of Bedford, Indiana, is, however, an exception to this rule. Not only is the color pleasing and its lasting qualities fair, but its fine even grain and softness render it admirably adapted for carved work. Several of the Southern and Western States have an abundance of lime- stone and sandstones suitable for general building purposes, but so far as observed few, if any of them, are of such quality as ever to attain anything more than a local market. Kentucky has limestones in abun- dance and of good quality. Kansas is pre-eminently a State of lime- stones. These are, however, for the most part soft and porous, of a dull color, and must be found lacking in lasting qualities in other than a very dry climate. A white, chalky limestone is quarried in Trego County, in this State, and is used in the manufacture of whiting. Oth- erwise than from the product of this quarry, all the other wrhiting man- ufactured in the United States is said to be prepared from imported English chalk. Texas furnishes cretaceous limestones of fine and com- 528 THE POPULAR SCIENCE MONTHLY. pact texture from the vicinity of Austin. Some of these take a good polish, and might be used as marbles. No lithographic limestones that can compare with the imported stone have as yet been found in this country. Silverville, Indiana ; Glascow Junction, Kentucky ; and Saverton, Missouri, each produce fine, even-grained stones of a drab color which have been put upon the market at various times as lithographic stone, but so far as is known to the writer the Missouri stone is the only one now used for this purpose. The total amount of sandstone quarried in the United States dur- ing the census year was 24,776,930 cubic feet, valued at $4,780,391 ; the same being the product of 502 quai*ries representing an invested capital of $6,229,600. Sandstone-quarrying in the United States doubtless began with the itinerant working of the extensive Triassic deposits of " brown-stone " in the vicinity of Portland, Connecticut. Where now are excavations upward of one hundred feet in depth, were then steep cliffs overhang- ing the river, and from these the inhabitants of Middletown and neighboring localities early began to carry away material for general building purposes as well as for monuments and gravestones. To such an extent had this system of free quarrying been carried, that as early as 1665 a resolve was passed similar in purpose to that relative to the granite bowlders on the Quincy Commons, to the effect "that no one shall dig or raise stone at the Rocks on the east side of the river " (now Portland) " but an inhabitant of the town, and that twelve pence shall be paid to the town for every ton of stone taken." Not long after this the quarries thus opened passed from the possession of the town into that of private parties, and what is now known as Brainard's quarry is said to have been operated since 1700. There are now three quarries situated in a line along the river's bank at this place, from which have been taken altogether some 4,300,000 cubic feet of stone, or enough to build a wall nearly two and a half feet high, and one foot thick, around the entire State ! Of the same geological age and general appearance as those of Connecticut, though varying slightly in color and texture, are the brown and red sandstones quarried in Massachusetts, Pennsylvania, New Jersey, and Maryland. In all of these the cementing material that binds together the rounded and angular grains of which they are composed is largely iron oxide, which gives the color to the stone and yet leaves it soft enough to be worked at only a very moderate cost. On account of their pleasing colors and easy working qualities these stones have been great favorites for general building purposes, as the monotonous rows of brown-stone fronts in New York city too well attest. Of about equal importance with these brown Triassic stones are the light-colored subcarboniferous sandstones of Ohio and elsewhere. BUILDING AND ORNAMENTAL STONES. 529 These are all fine-grained stones with but little cementing material, the individual grains of which they are composed being held together simply by the cohesion induced by the pressure to which they were subjected at the time of their consolidation. They therefore work very readily, especially when newly quarried, and have been used more extensively for carved work than any other of our sandstones. They are best represented in the market to-day by the so-called Euclid " blue-stones " and Berea " grits " of Ohio, the former being deep blue- gray in color, while the latter is very light. They are well known to the general public in the form of window stools and caps, door posts and steps, for which purpose they have been very extensively used in all our large cities. Somewhat resembling in general appearance the Euclid blue-stones, but of greater geological age, are the dark, blue-gray compact "gray- wackes," or flag-stones, so extensively quarried in Ulster County, New York, and other parts of this State and Pennsylvania. These stones are of fine and even texture, and split readily from the quarries in slabs, usually but a few inches thick. They are therefore eminently suited for flagging, to which usage they are extensively applied, though they also used for steps and general trimming purposes. The rock quarried at Barryvale, in Sullivan County, is of a similar nature. It was from quarries at this last-named locality that was taken the monster flag-stone, twenty-five feet two inches long, by fifteen feet wide and eight inches thick, that now forms a portion of the sidewalk in front of the Vanderbilt residence on Fifth Avenue, New York. It should be stated, however, that the size of this block was limited only by the means of transportation, and much larger could be obtained at the quarries if desired. Another very important group of sandstone, but of still greater geological antiquity, belonging to the Medina period of the Upper Silurian formations, is quarried extensively at Albion and Medina, near Rochester, New York. These stones are usually of a reddish color and contain a larger portion of siliceous cementing material than any of those yet mentioned ; they are therefoi'e much harder and much less pervious to moisture. The stones are used for all manner of building purposes, flagging, and street-paving. A somewhat simi- lar stone, but of brighter color and Potsdam age, is quarried in the town of Potsdam, in St. Lawrence County, in the same State. This is the stone used in the construction of the Columbia College buildings in New York city. Sandstones of this nature, i. e., with the larger proportion of sili- ceous cementing material, are among the most durable of all our build- ing-stones ; but their extreme hardness, and often poor colors are great drawbacks to their extensive use. In process of dressing such stone an exceedingly fine white dust arises and remains for a long time sus- pended in the air, to the great inconvenience of the workmen, who tell vol. xxvn. — 34 530 THE POPULAR SCIENCE MONTHLY. marvelous stories of its penetrating powers. They have been known to assert that, if an empty and hermetically sealed glass bottle be placed within the sheds where such stones are being cut, it will shortly be found with a fine white deposit of the dust upon the bottom and on the inside, and no argument can convince them that it came there otherwise than through the pores of the seemingly impervious glass ! The quarrying of slate for roofing purposes is an industry of comparatively recent origin in the United States, few of the quarries having been operated for a longer period than twenty or thirty years. The earliest opened and systematically worked are believed to have been those at West Bangor, Pennsylvania, which date back to 1835. The abundance of slate tombstones in many of our old churchyards, however, would seem to prove that for other purposes than roofing these stones have been quarried from a much earlier pe- riod. It is stated, moreover, that as early as 1721 a cargo of twenty tons of split slate was brought into Boston from Hangman's Island in Braintree Bay, which may have been used wholly or in part for roof- ing purposes ; but the greater part of the material for this purpose was imported directly from Wales. It is interesting to note, in this connection, that, daring the business depression of 1876-'80, almost the entire product of the American quarries was exported to England, where it sold for even less than the Welsh slates, though necessarily at very small profits. The return of more prosperous times, however, created a local demand, and the export trade hak been largely de- creased accordingly, though considerable quantities are still sent out to the West Indies, South America, England, Germany, and even New Zealand and Australia. At present not far from $3,328,150 are invested in the slate-quar- ries of the United States, and the value of the annual product is some $1,529,985. Pennsylvania is the leading State in this industry, her quarries be- ing located in Lehigh, Northampton, and York Counties, in the eastern part of the State. These slates are all blue-black in color ; as are also those from Maine, Massachusetts, and Maryland. The Vermont slates are of a greenish or purple color, while those of New York are mostly purple and red, the latter color being found in extensive deposits near Granville, in Washington County. Besides for roofing purposes, slates are used for billiard-tables, mantels, floor-tiles, flagging, and in the manufacture of school-slates. For the last-named purpose a soft, even-grained stone is required, and almost the entire supply is at present brought from Pennsylvania and Vermont. Of late years, the business of marbleizing slates for mantels and fireplaces has become an important industry. All kinds of stones can be imitated by this process, but that most commonly seen is the green verd-antique marble and the variegated marbles of Tennessee. Like BUILDING AND ORNAMENTAL STONES. 531 many counterfeits, however, the work is too perfect in execution, and need deceive none but the most inexperienced. Concerning the future of the building stone industry little that is definite can be said. As the population increases and becomes more fixed in its abode, there naturally arises a demand for a more durable building material than wood, which is still largely used in the country towns and smaller cities. As wealth accumulates, too, better and more substantial buildings are erected, which are often profusely embellished with the finer grades of ornamental stones. The demand, then, is sure to increase. In regard to the amount of the supply there can be ques- tion ; everything would seem to depend on the quality, variety, and cost of working of yet-to-be-discovered material. Are we to continue to import as now the finer grades of our ornamental stones, or will our own quarries, yet perhaps to be opened, produce enough and more than enough for our own use ? I am inclined to think the latter. In many of the Eastern and earliest to be settled States very little is yet known regarding their final resources. In Maine, for instance, fully one half of the State is as yet an unknown land. Its present quarries are nearly all immediately upon the coast. What are the resources of its immense interior can not with certainty be foretold. In the Southern and Western States and Territories, this condition of affairs is naturally greatly magnified. The Virginias, North and South Carolina, and Georgia, all contain excellent material, none of which is now in our principal markets. Michigan can furnish brown sandstones in great abundance fully equal to any now quarried in the more Eastern States, and other sandstones of a beautiful mellow tint are known to occur in Western Arizona. The Rocky Mountain region contains an abundance, both in variety and quantity, of granites, sand- stones, marbles, and the more recent volcanic rocks, as basalts, rhyo- lites, and trachytes. Some of these are very beautiful, excelling any- thing in this respect from the Eastern States. Red granites far ex- celling the red Scottish granites of Peterhead, or the celebrated Egyp- tian " Syenite," occur in inexhaustible quantities. We have seen a black-and-white breccia marble from Pitkin, Colorado, which bids fair to be a formidable rival of the imported Portoro marble from the Monte d'Arma quarries, if it occurs in sufficient quantities and is accessible. A fine field for exploration is offered in the extensive stalagmitic deposits on the floors of the numerous caverns so prevalent in many parts of the country. These deposits, as is well known, are identical in composition with the celebrated "onyx" marbles of Cali- fornia, Mexico, and Egypt, already mentioned. The red and purple porphyries so abundant in New Hampshire, Eastern Massachusetts, and other parts of the country, offer an unfailing supply of beautiful and durable ornamental stones, but which are at present kept out of the market, owing to the great cost of working. This leads us, in conclusion, to an important item in this connection 532 THE POPULAR SCIENCE MONTHLY. that must not be overlooked, which is the fact that, with our present high rates of labor in this country, many of our finest grades of orna- mental stones can not compete in the market with the imported article, even though greatly exceeding them in point of beauty. In the ma- jority of marbles those lines or spots that give to any stone its peculiar attractiveness are in reality flaws, and hence their presence must add greatly to the cost of working. It is safe to say that the beautiful breccia marble from the French Pyrenees, which has been used for wall-panels in the cash-room of the Treasury Building at Washington, would not be worked to any extent from quarries in this country, so long as the imported article can be obtained at present rates. This fact is rendered probable by the cases of the Maryland breccia and the Vermont verd-antique already mentioned. Neither of these is in the market, simply because the imported marble can be furnished at lower prices. With improved machinery and methods of workman- ship there seems, however, no doubt but we may in time compete with foreign cheap labor not only in our own markets, but foreign ones as well. ■»»♦• THE DARWIN MEMORIAL. THE ADDKESS OF PEOFESSOE HUXLEY, AND THE EEPLY OF THE PEINCE OF WALES. IT is not often that the unveiling of a statue is attended with an inter- est at all comparable with that which characterized this ceremony as performed last Tuesday [June 9th] in the great hall of the Natural History Museum. If the greatness of a man is to be estimated by the measure in which he has influenced the thoughts of men, it is scarcely open to question that the greatest man of our century is Charles Dar- win. As Professor Huxley remarked in the course of his singularly judicious and well-balanced address, Mr. Darwin's work has not only reconstructed the science of biology, but has spread with an organizing influence through almost every department of philosophical thought. Yet it was not merely the greatness of the naturalist which invested the proceedings in the Natural History Museum with an interest so unique. It was known to the whole assembly that the man whom they delighted to honor was one whose moral nature had been cast in the same lines of simple grandeur as those which belonged to his intel- lectual nature. It therefore only needed a passing allusion from Pro- fessor Huxley to enable the whole assembly to reflect that it was due as much to massiveness of character as to massiveness of work that within three years of his death Mr. Darwin's name should constitute a new center of gravity in every system of thought. And it was this reflection which gave to the ceremony so unusual a measure of inter- est. Around the statue were congregated the most representative men THE DARWIN MEMORIAL. 533 of every branch of culture, from the Prince of Wales and the Arch- bishop of Canterbury to the opposite extremes of radicalism and free thought. Indeed, it is not too much to say that there can scarcely ever have been an occasion on which so many illustrious men of oppo- site ways of thinking have met to express a common agreement upon a man to whom they have felt that honor is due. The international memorial could not in any nation have found a more worthy site than the one in which it has been placed ; but, if anything could have added to the "solemn gladness " with which the personal friends of Mr. Dar- win witnessed the presentation of this memorial, it must have been the evidence which the assembly yielded that, among the innumerable dif- ferences of opinion which it represented, his memory must henceforth be always and universally regarded as a changeless monument of all that is greatest in human nature, as well as of all that is greatest in human achievement. Concerning the statue itself, we have only to speak in terms of almost unqualified praise. It is, in the truest sense of the phrase, a noble work of art. The attitude is not only easy and dignified, but also natural and characteristic ; the modeling of the head and face is unexceptionable, and the portrait is admirable. The only criticism we have to advance has reference to the hands, which not only do not bear the smallest resemblance to those of Mr. Darwin, but are of a kind which, had they been possessed by him, would have rendered im- possible the accomplishment of much of his work. Although this mis- representation is a matter to be deplored, it is not one for which the artist can be justly held responsible. Never having had the advantage of seeing Mr. Darwin, Mr. Boehm has only to be congratulated upon the wonderful success which has attended his portraiture of the face and figure ; the hands were no doubt supplied by guess-work, and therefore we have only to regret that the guess did not happen to be more fortunate. The following is the address made by Professor Huxley, in the name of the Darwin Memorial Committee, on handing over the statue to his Royal Highness the Prince of Wales, as representative of the Trustees of the British Museum : Your Royal Highness : It is now three years since the announce- ment of the death of our famous countryman, Charles Darwin, gave rise to a manifestation of public feeling, not only in these realms, but throughout the civilized world, which, if I mistake not, is with- out precedent in the modest annals of scientific biography. The causes of this deep and wide outburst of emotion are not far to seek. We had lost one of those rare ministers and interpreters of Nature whose names mark epochs in the advance of natural knowl- edge. For, whatever be the ultimate verdict of posterity upon this or that opinion which Mr. Darwin had propounded ; whatever adumbra- 534 THE POPULAR SCIENCE MONTHLY. tions or anticipations of his doctrines may be found in the writings of his predecessors ; the broad fact remains that since the publication, and by reason of the publication, of the " Origin of Species," the fun- damental conceptions and the aims of the students of living Nature have been completely changed. From that work has sprung a great renewal, a true " instauratio magna " of the zoological and botanical sciences. But the impulse thus given to scientific thought rapidly spread be- yond the ordinarily recognized limits of biology. Psychology, Ethics, Cosmology were stirred to their foundations, and the " Origin of Spe- cies " proved itself to be the fixed point which the general doctrine of evolution needed in order to move the woild. " Darwinism," in one form or another, sometimes strangely distorted and mutilated, became an every-day topic of men's speech, the object of an abundance both of vituperation and of praise, more often than of serious study. It is curious now to remember how largely, at first, the objectors predominated ; but, considering the usual fate of new views, it is still more curious to consider for how short a time the phase of vehement opposition lasted. Before twenty years had passed, not only had the importance of Mr. Darwin's work been fully recognized, but the world had discerned the simple, earnest, generous character of the man that shone through every page of his writings. I imagine that reflections such as these swept through the minds alike of loving friends and of honorable antagonists when Mr. Darwin died ; and that they were at one in the desire to honor the memory of the man wrho, without fear and without reproach, had successfully fought the hardest intellectual battle of these days. It was in satisfaction of these just and generous impulses that our great naturalist's remains were deposited in Westminster Abbey ; and that, immediately afterward, a public meeting, presided over by my lamented predecessor, Mr. Spottiswoode, was held in the rooms of the Royal Society, for the purpose of considering what further steps should be taken toward the same end. . It was resolved to invite subscriptions, with the view of erecting a statue of Mr. Darwin in some suitable locality ; and to devote any surplus to the advancement of the biological sciences. Contributions at once flowed in from Austria, Belgium, Brazil, Denmark, France, Germany, Holland, Italy, Norway, Portugal, Rus- sia, Spain, Sweden, Switzerland, the United States, and the British colonies, no less than from all parts of the three kingdoms ; and they came from all classes of the community. To mention one interesting case, Sweden sent in 2,296 subscriptions " from all sorts of people," as the distinguished man of science who transmitted them wrote, " from the bishop to the seamstress, and in sums from five pounds to two pence." The Executive Committee has thus been enabled to carry out the THE DARWIN MEMORIAL. 535 objects proposed. A " Darwin Fund " has been created, which is to be held in trust by the Royal Society, and is to be employed in the promotion of biological research. The execution of the statue was intrusted to Mr. Boehm ; and I think that those who had the good fortune to know Mr. Darwin per- sonally will admire the power of artistic divination which has enabled the sculptor to place before us so very characteristic a likeness of one whom he had not seen. It appeared to the committee that, whether they regarded Mr. Darwin's career or the requirements of a work of art, no site could be so appropriate as this great hall, and they applied to the Trustees of the British Museum for permission to erect it in its present position. That permission was most cordially granted, and I am desired to tender the best thanks of the committee to the trustees for their will- ingness to accede to our wishes. I also beg leave to offer the expression of our gratitude to your Royal Highness for kindly consenting to represent the trustees to-day. It only remains for me, your Royal Highness, my lords and gen- tlemen, Trustees of the British Museum, in the name of the Darwin Memorial Committee, to request you to accept this statue of Charles Darwin. We do not make this request for the mere sake of perpetuating a memory ; for, so long as men occupy themselves with the pursuit of truth, the name of Darwin runs no more risk of oblivion than does that of Copernicus or that of Harvey. Nor, most assuredly, do we ask you to preserve the statue in its cynosural position in this entrance-hall of our National Museum of Natural History as evidence that Mr. Darwin's views have received your official sanction ; for Science does not recognize such sanctions, and commits suicide when it adopts a creed. No ; we beg you to cherish this memorial as a symbol by which, as generation after generation of students of Nature enter yonder door, they shall be reminded of the ideal according to which they must shape their lives, if they would turn to the best account the opportuni- ties offered by the great institution under your charge. The following reply was made by his Royal Highness the Prince of Wales : Professor Huxlet and Gentlemen : I consider it to be a high privilege to have been deputed by the unanimous wish of my col- leagues, the Trustees of the British Museum, to accept, in their name, the gift which you have offered us on behalf of the Committee of the Darwin Memorial. The committee and subscribers may rest assured that we have most willingly assigned this honorable place to the statue of the great Englishman who has exerted so vast an influence upon the 536 THE POPULAR SCIENCE MONTHLY. progress of those branches of natural knowledge the advancement of which is the object of the vast collections gathered here. It has given me much pleasure to learn that the memorial has received so much support in foreign countries that it may be regarded as cosmopolitan rather than as simply national ; while the fact that persons of every condition of life have contributed to it affords remarkable evidence of the popular interest in the discussion of scientific problems. A memorial to which all nations and all classes of societv have con- m tributed can not be more fitly lodged than in our Museum, which, though national, is open to all the world, and the resources of which are at the disposal of every student of Nature, whatever his condition or his country, who enters our doors. — Nature. MODERN BRONZES.* By PEEEY F. NUESEY, C. E. WE had in the earlier ages of mankind a rough and a polished stone age, a bronze age, and an age of iron, each distinguished by the character of the material that was predominantly used by men for their wsapons and tools, and have now added to those ages one of steel. In a similar manner we are now entering upon a revival of the bronze age, in which that substance in its varieties is to be put through stages of improvement like those that iron and steel have undergone. Many varieties of bronze have been produced within the last few years that possess features strongly distinguishing them from the ancient alloys, and some very remarkable qualities as compared with them, in view of which they are frequently used in place of even iron and steel, The bronzes of the ancients were composed of copper and tin, as is also what is now regarded as bronze pure and simple, mixed in propor- tions varying according to the purpose for which the compound is intended. Other substances, however, are often added, without un- classifying the product, which is still called bronze, provided copper and tin are the chief constituents. Among these substances are zinc, lead, phosphorus, manganese, silicium, iron, nickel, arsenic, antimony, and sulphur. It is the addition of certain proportions of one or other of such substances that constitutes the modern development of bronze manufacture, and which has given us some of the most useful and at the same time some of the most remarkable alloys known. These comprise no fewer than eleven distinct products, all of which find their uses in connection with the practice of engineering. They are : phosphor-bronze, silicium-bronze, manganese-bronze, delta-metal, phos- * From a paper read before the Society of Engineers. MODERN BRONZES. 537 phor-copper, phosphor-manganese bronze, phosphor-lead bronze, phos- phor-tin, aluminum-bronze, silveroid, and cobalt-bronze. There are also other bronzes which are used as substitutes for gold in cheap imi- tation jewelry, but they do not come within the scope of the present paper. The action of phosphorus on copper alloys is principally due to its reducing qualities, by virtue of which the oxygen absorbed by the molten metal is removed, or the oxides formed thereby are eliminated, and the degree is imparted of homogeneity, strength, and toughness peculiar to the chemically pure metal. The phosphorus, by producing these effects, is converted into a cuprous oxide, which floats on the surface of the molten metal in the shape of a very fluid slag, while the superfluous quantity combines with the metal. It is not, therefore, desirable to add to the bronze a larger quantity of phosphorus than will suffice to reduce the oxide present. Phosphor-bronze was first prepared by Dr. Kunzel, of Dresden, and was brought into practical use in England early in 1873. The alloys of this class are composed of copper, tin, and phosphorus, and other ingredients in variable proportions, and are made to be either as ductile as copper, as tough as iron, or as hard as steel, according as the pro- portions of the constituents are varied. The alloys used for rolling and drawing have very different proportions from those employed for castings, bearings, and parts of machinery. The castings of this metal are perfectly sound and homogeneous. Wherever strength, toughness, and durability are desired, phosphor-bronze is found to be better adapted than gun-metal and brass, and in many cases than iron and steel. Having the advantage of not becoming crystalline under the action of repeated shocks and bendings, it is well adapted for making wire-rope, and, not being acted upon by corrosive liquids or the atmos- phere, its value as a metal remains constant. The principal varieties of phosphor-bronze, which are produced by slightly varying the pro- portions of the constituents, are phosphor-bronze duro A, a very dense metal, adapted for bearings carrying heavy wheels running at great velocities, and generally for all quick-speed purposes ; and phosphor- bronze duro B, which is intended for the bearings of hot-neck rolls, and for all bearings having to withstand great pressure. Silicium-bronze was invented by M. Lazare Weiller, of Angouleme, in the search for a material for telegraph-wires, which, together with all the desirable properties of phosphor-bronze, should have a better conducting power. In it phosphorus is replaced by a silicious metal- loid, by the incorporation of which a wire is produced offering the same resistance to rupture as phosphor-bronze wire, by the use of which telegraph lines may be furnished with a light, unoxidizable wire, having all needed electrical efficiency. It is also affirmed of wires of this bronze that they are of equal strength with ordinary wires, while not one tenth as heavy ; and that, if broken, they will not fall to the 538 THE POPULAR SCIENCE MONTHLY. ground as ordinary wires do, but, by virtue of their high elasticity, will spring back and coil up close to the standards. It has long been known that the hardness of bronze could be in- creased by adding iron to it, but that quality appears to be acquired at the expense of ductility and toughness, and for that reason, prob- ably, such alloys have never come into general use. Mr. Alexander Parkes, and the late Mr. J. D. Morries Stirling, were probably the first to propose and carry into practice the use of manganese for improving the quality of bronze. Mr. Parkes combined manganese alone with copper, and used this alloy to form improved alloys of brass and yel- low metal, of which to make sheathing, rods, wire, nails, and tubes. Mr. Stirling, in 1848, proposed to employ manganese in various brass alloys in which iron was present ; and a metal introduced by him was used for some time in railway-carriage bearings. It, however, lacked strength, hardness, and ductility, and has long since been superseded. A manganese-bronze having all the requisites of a useful alloy was introduced in 187G by Mr. P. M. Parsons. It is prepared by mixing a small proportion of ferro-manganese with copper, after which various alloys are formed. The ferro-manganese is melted in a separate cru- cible, and is added to the copper when in a fluid state. The effect of this combination is similar to that produced by the addition of ferro- manganese to the decarburized iron in a Bessemer converter. Accord- ing to Mr. Parsons, while a part of the manganese cleanses the copper of any oxides it may contain by combining with them and forming a slag, another part, with the iron, becomes permanently combined with the copper, whereby the strength, hardness, and toughness of the com- pound are modified, according as the proportions of the constituents are varied. Five different qualities of manganese-bronze are made. In the number one quality the zinc alloyed with the copper is consid- erably in excess of the tin. It may be worked hot or cold, and has great tensile strength and elasticity. Manganese-bronze number two is stronger, and can be cast in sand for special purposes where strength, hardness, and toughness are required ; but it has to be melted in cru- cibles. One of its most important applications is to the production of articles cast in metal molds under pressure ; and the articles thus made have the strength, toughness, and hardness of cast-steel, without any of its defects. It is perfectly homogeneous, and, while not pos- sessing a fibrous texture derived from rolling or hammering, is still fibrous in character, in all directions alike, and, when broken, shows a beautiful silky fracture. It can be cast upon any object, on which it will shrink with a force equal to its elastic limit, and, when released, will show an amount of resilience about double that of steel. Its hard- ness is about equal to that of mild steel. The number three quality is composed chiefly of copper and tin in about the same proportions as gun-metal, combined with a large per- centage of ferro-manganese. Its chief characteristics are great trans- MODERN BRONZES. 539 verse strength, toughness, and hardness, the facility with which it can he cast, and the soundness and uniformity of the castings produced. This quality is used for wheel-gearing, supports and connections of machines, crank-pin brasses, the shells of main and other bearings of engines, axle-boxes, and parts of locomotive-engines. It is also adapted for statuary and for large bells. Its most important appli- cation appears to be for making screw-spellers, for which, in its qualities of strength, non-corrosiveness, and perfect trueness in cast- ing, it seems to be superior to any other substance yet found. The qualities numbers four and five have no particular claim to strength, but are useful for bearings, slide-valves, slide-blocks, piston- rings, and other purposes in which friction has to be taken account of. Delta-metal, the second and latest example of the successful addi- tion of iron to bronze, was introduced, in 1883, by Mr. Alexander Dick, who named it with the Greek equivalent for the initial of his surname. His preliminary experiments were directed to removing the inequalities in the properties of the iron-bronze alloys previously attempted, and he found that all depended on getting exactly the right proportion of iron and preventing its oxidation during the process of remelting. Delta-metal in color resembles gold alloyed with silver. It can be worked hot and cold. When melted, it runs freely, and the castings produced from it are sound and of a fine, close grain. It can not be welded, but can be brazed, and, when of suitable thickness, " burned." The varieties designed for working hot are capable of being stamped or punched, similar to wrought-iron and steel, into a variety of arti- cles which have hitherto been cast in bronze or brass. This property is of much importance, for the articles thus turned out are cheaper and stronger than brass-castings. The iron introduced into the com- pound by Mr. Dick's process is really chemically combined ; and the alloy does not rust, and has no action on the magnetic needle. Delta- metal may be used to replace the best brass and gun-metal, and in many instances iron and steel also — for parts of rifles, guns, and tor- pedoes, tools for gunpowder-mills, parts of bicycles, gongs, various domestic articles, spindles for steam- and water-valves, plungers, pump- rods, and boats. Phosphor-copper is a preparation devised by Mr. W. G. Otto, of Darmstadt, for the purpose of furnishing engineers and founders with a compound, by adding certain proportions of which to a given bulk of metal they can obtain a phosphor-bronze suitable for various purposes. An article called phosphor-manganese-bronze is in the market, but the manufacturer has not furnished a description of it. Phosphor-lead bronze, introduced in 1881 by Messrs. K. H. Kuhne & Co., of Lobau, near Dresden, is regarded as specially adapted for all purposes where metal is subjected to constant wear or continuous friction. The introduction of lead into its composition and its homo- geneousness are said to give it special properties, by reason of which 540 THE POPULAR SCIENCE MONTHLY, the advantages are claimed for it of self -lubrication, greater wearing capacity than any other metal or alloy, coolness under friction, great tensile strength combined with hardness, and non-liability to fracture. Phosphor-tin is a compound designed to be added to copper for the making of phosphor-bronze. The history of the practical manufacture of aluminum does not ex- tend very far back into the past ; in fact, its commencement dates within the limits of the present generation. The three International Exhibi- tions which have been held in Paris since aluminum began to be worked on a commercial scale form so many landmarks in its progress. In 1855 it was met with for the first time in the Palais d'Industrie, in the form of a large bar, and was exhibited as silver produced from clay. In the Exposition of 18G7 it was to be seen in a more advanced stage, worked up into castings and various kinds of useful and ornamental articles. There also for the first time was seen the alloy aluminum- bronze. The Paris Exhibition of 1878 witnessed the maturity of the aluminum manufacture and its establishment as a current industry, having a regular demand and supply for certain purposes within the limits permitted by its somewhat high price. A little more than two years ago Mr. James Webster perfected his invention for producing aluminum, which is now being practically worked, and gives, it is claimed, alumina without a trace of iron, and free from contamina- tion with other foreign substances. The process is being worked by the Aluminum Crown Metal Company, and the metal itself combines strength and lightness with elegance of appearance and general utility. The bronze is of two kinds — white and yellow — the former being used for cutlery and other table requisites where silver and plated goods are now employed, for metallic fittings, and for every purpose where a non-oxidizing, bright surface, with strength, is desired. The yellow metal is adapted, and is used for articles and for details of machinery where gun-metal and other alloys are now employed. It is said to stand well in engine-bearings, and to give satisfactory results when used in screw-propellers. The bronze is made in five qualities, and each quality is made hard or soft as may be required. Silveroid, a metal introduced to public notice early in 1884, is an alloy of copper and nickel adjusted with zinc, tin, or lead, in various proportions, according to the purpose for which it is intended ; but the secret of success in the manufacture is said to lie in a special method of treatment at a certain point in the process. This alloy is a metal of great whiteness, brilliancy, closeness of grain, and tensile strength. Cobalt -bronze has been introduced since silveroid, by the same manufacturers, Messrs. Henry Wiggin & Co., who produced that metal. It is whiter and slightly more expensive than silveroid, and is interesting as containing small quantities of cobalt, with the most de- sirable qualities of that metal, particularly its malleability. It is manu- MEASURES OF VITAL TENACITY. 541 factured in several qualities, the higher grades of which are eminently suitable for casting purposes, have a close, steel-like surface, are sus- ceptible of a high polish, are hard and tough, and possess great tensile strength. MEASURES OF VITAL TENACITY. Br Dr. B. W. RICHARDSON, F. R. S. IN the observations which I have made on animals passing into death by the lethal process, nothing has impressed me more than the curious differences of vitality or vital values of different animals. The differences are so great they seem almost inexplicable, and in many respects they are so. To some extent, however, they come under law, and we may therefore hope that by carefully continued research what is now difficult and involved may be rendered, in time, simple and perfectly clear. The first series of observed facts relate to vital differences in ani- mals of different species. In illustration I may take the cat and the dog. Between these animals the distinction of vitality exists irrespect- ively of age, and of all other conditions and circumstances of which I can gather information. Of the cat it is commonly said that it has nine lives. By this say- ing nothing very definite is meant beyond the opinion that under vari- ous kinds of death the cat lives much longer than other animals that have to be killed by violent means. When any question is asked of the police or of other persons who have to take the lives of lower ani- mals, they tell you, without exception, according to my experience, that the cat is the most difficult to destroy of all domestic animals, and that it endures accidental blows and falls with an impunity that is quite a distinguishing characteristic. The general impression conveyed in these views is strictly correct up to a certain and well-marked degree. By the lethal death, the value of the life of the cat is found to be, at the least, three times the worth of the dog. In all the cases I have seen in which the exactest comparisons were made, the cat outlived the dog. A cat and dog of the same ages being placed in a lethal chamber, the cat may, with perfect certainty, be predicted to outlive the dog. The lethal cham- ber being large enough to hold both the cat and the dog, the vapor inhaled by the animals being the same, with every other condition identical, this result, as an experimental truth, may be accepted with- out cavil. The differences, always well marked, are sometimes much longer than would be credible in the absence of the evidence. I have once seen a cat, falling asleep in a lethal chamber in the same period as a dog, remain breathing, literally, nine times longer, for the dog died 542 THE POPULAR SCIENCE MONTHLY. within live minutes, and the cat not only continued to breathe, in profoundest sleep, for forty-five minutes, but would have been recov- erable by simple removal from the vapor into fresh air if it had been removed while yet one act of breathing continued. This, however, was exceptional, because the cat in the same lethal atmosphere as the dog does not, as a rule, live more than thrice as long ; i. e., if the dog ceases to breathe in four minutes, the cat will cease in from ten to twelve minutes after falling asleep. The character of the vapor used does not make any difference, relatively. Carbonic oxide, carbonic acid, chloroform-vapor, carbon- bisulphide vapoi', yield the same relative results. Pure carbonic oxide kills with intense rapidity, but it kills the cat less quickly than the dog. If instead of a lethal vapor prussic acid be used, in administra- tion by the mouth, the cat dies more slowly than the dog. The same is true in respect to death by drowning. Still more curiously, recovery from apparent death is much more frequent in the cat than in other domestic animals. Mr. Warrington once observed a cat recover from apparent absolute death by prussic acid, eight hours after it had lain as if dead. I once saw a young cat come back to life after two hours of immersion under cold wrater. I do not know many facts bearing on tenacity of life in other ani- mals, but I have observed that sheep in a lethal atmosphere die very rapidly, goats much less rapidly, and pigeons more rapidly than com- mon fowls. There is, apparently, a specific tenacity in all species. In animals of the same species there are distinctions determinable by peculiarities in the animal itself. In one instance where a large number of dogs were put to sleep in the lethal chamber, one was found in deepest sleep, but still breathing, side by side and partly covered by another that was not only dead but cold and rigid. A similar fact occurred last year in the human subject in a mine. A father and son killed by fire-damp lay together, the father dead, the son living, though he, the son, had come first under the influence of the lethal gas. In all the fatal accidents to the human subject from the administration of chloroform or other narcotic vapor we see the same illustration. I doubt whether in any one of these unhappy events the death has been induced by what would be, under the com- mon run of administrations, a fatal dose. But some die from a dose that would not so much as narcotize others. An analogous series of facts is met with in relation to the effects of physical and mental shocks and to surgical operations. The variation of measure of tenacity of life is unquestionable. What is the reason of it ? What is there in one species of animal that gives a measure of tenacity over another ? Why, for instance, is the cat more tenacious of life than the do
