OMONG the results of modern, nay, of quite recent, scientific research, I know none more impressive than the recognition of the stream of life, animal and vegetable, which has flowed over the earth during millions of past years. Starting we know not how, coming we know not whence, the stream of life has left traces of its existence in all the rock strata of the earth from the palseozoic onward through the secondary and tertiary .systems, onward to the pleistocene and to those strata which are called recent, though some of them, measuring their duration as men measure time in consider- ing the progress of i-aces and of nations, seem of vast antiquity. Let us consider how the history runs, not entering into details, but taking such a survey as shall bring the broad features of the scene before us, and show its cosmical rather than its merely terrestrial aspect. How first the earth's crust was formed we know not, for the traces of the first formative processes have long since been swept away. Probably each portion was formed again and again, .solidifying and melting, and resolidifying and re- melting, many times over before it finally assumed the solid condition. In some cases the solid part of the crust, being of greater specific gravity than the molten, would sink as fast as formed, to melt again, and again return to the surface, not finally solidifying in a permanent way until many hundreds of thousands, perhaps million.s, of years had passed. Whether any part of the present crust of the earth can be regarded as representing the solid crust fashioned when first these alternations were completed may well be doubted. The so- called Archaean rocks have been supposed by some to be the primeval crust of the planet. But others regard them as belonging to a much later stage. And others yet admit that we cannot tell what interval separated the formation of these, the most ancient rocks of the present earth, from the first formation of a ci'ust upon that region of the eartii where the Archfean rocks are found? But this, at any late, is certain : Whenever the Archaean rocks, which have been exposed in various parts of the earth by long continued processes of denudation, were actually formed, they have mostly (if not all) undergone great changes during the time that they have been buried beneath strata formed later. Moreover, it must be remem- bered that the lower primary rocks which were originally deposited on these Archsean rocks were formed from them by processes ot denudation, and that, therefore, we cannot expect to find anywhere the ancient face of the first-formed cru.st. Indeed, denudation in those remote times, certainly 20,000,000, and probably 100,100,000 years ago, was 'a very much more active process than denudation as it takes place now. For the waters of the ocean were greater by one-half in quantity, were intensely hot, were loaded with destructive acids, were more actively moved ; while the air was not the pure life-nourishing air we breathe now, but an atmo.-^phere whose breath was fire, laden with destructive vapours, swept by tremendous storms, and beai-ing clouds fiom whose bosom descended torrents of hot water, mixed with sulphuric acid, boracic acid, and other powerfully acting liquids. By these destructive agencies the first formed crust of the earth must have been rapidly denuded, and fresh layers formed at the lower levels, to be raised while the higher levels were dspi'essed, fresh denuda- tion following, and fresh layers being formed, probably during millions of years, before life was possible upon the earth. It appears to me, indeed, that in the existence of fossil traces of life, animal and vegetable, in the lowest of the palseozoic rocks, we have decisive evidence that immense periods of time must have separated the formation of the rocks next below them from the first formation of the earth's solid crust. For it is certain that during millions of years following the .solidification of the earth's crust, life must have been impossible. Even apart, therefore, from the decision of the much-vexed question whether the forma- tion named Eozoon found in the Archa?an limestones of Canada is to be regarded as the fossil evidence of a reef- building animal (a Foraminifer), which would throw back still farther the time of the first .solidification of the crust, we may safely conclude that the Archaean rocks represent formations which had no existence with their present structure until millions of years after the earth first had a solid surface. With our present ideas respecting the laws of biological evolution (ideas based, be it rememljered, on observed facts) we may deduce the same conclusion from the character of the fossils found in the lowest of the primary or palaeozoic rocks. We know that whatever may have been the actual beginnings of animal and vegetable life on the earth, the flora and fauna even of the lowest palfeozoic strata cannot have come into existence save as the product of immense periods of past time. In the Lower Silurian rocks, indeed, we have but few fossil traces of the vegetation of the remote time when they were formed ; but this is chiefly due to the fact that the Lower Silurian rocks are chiefly of marine formation. But the animal life, even of the oldest .stratified rocks, suffices to decide the question of duration in the most emphatic manner. Of course, the record is incomplete ; but in its very incompleteness it is the more decisive. We find complex and advanced forms, while the simpler forms, which necessarily existed at the same time, have left no trace of their existence. We can under.stand, then, how all forms of life, simple and complex, animal and vegetable, belonging to earlier strata, have disappeared, leaving no fossil evidence. And the positive evidence given by the fossils we do find, while thus giving to the negative evidence its true meaning, has its own definite and unmistakable value. If we consider, for example, but a single class — say the Trilobites (now extinct, though transiently represented in the Ciirly life stages of the King Crab) — we have as decisive evidence of enoi'mous preceding time-intervals as if we had fossils of 10,000 species of Silurian life, animal and vege- table. Those strange crustaceans existed at the remotest time to which geological history looks back, in many diflerent forms. Each had a strong head-shield to protect its head, a smaller tail-shield, and a ringed body which could be so curled that the two shields came together, and the whole body was protected. Some were nearly two feet in length (possibly some were much larger, but I speak ♦ KNOWTLKDGE ♦ [November 1, 1887. only of existent fossil evidence), and from this size they ranged down to minute forms, such as the Agnosfus Princi'ps, which was less than half an inch long. The number of rings also varied, the Agiwstus having but two, the ilicrodiscus four, the Eri»ni/.9 no fewer tlian twenty- four. Still more strikiug evidence of development, re- quiring hundreds of thousands of years for its full work, is found in the complex ej-es of the more advanced species of trilobites, for while the Ai/nostus was blind, most of the trilobites had eyes, some with fourteen facets, others with as man}' as 1.5,000 ! All thi-ough the Silurian period these crustaceans continued to thrive and multiply and develop into varied forms. But as the millions of years represented by the palaeozoic strata passed on, evolution in the race of trilobites resulted in the development of other races better fitted for the changed conditions of life ; we find no traces of any trilobites later than the carboniferous age; and in that age we find only four, all of which were small. Doubt- less many others existed of which no fossil traces have been left. Doubtless, also, triloliites continued to much later times than the fossil evidence attests. We cannot trace the series of crustacean i-aces which connect the trilobites with their descendants in secondary, tertiary, and recent ages. We cannot even tell what creatures have descended from the trilobites, excepting here and there a race or so, or along what line the descent travelled. We know only that those races which retained their triloliitic characteristics died out, those only survivinj. ■which adapted themselves by changes of structure to sur- rovinding conditions. But the Silurian rocks (the lowest and most ancient of all rocks known to have been life-bearing) were not without vegetable life, and the fossils telling us of the existence of vegetable life show also that immense periods of life must already have pissed before that life began. In the Upper Silurian strata we recognise the spores and stems of flower- less plants (cri/p/ogams). Club mosses and ferns were par- ticularly conspicuous in the flora of those palfeozoic times. "We can dimly picture the Silurian land," says Geikie, " with its waving thickets of fern, above which lycopod trees raised their fluted and starred stems, threw out their scaly, moss-like bi'anches, and shed tlieir spiky cones." But it is only because the cones and spore cases of the club mosses and the tough tissues of the fei-ns have been well fitted to withstand destructive agencies, and so have remained in fossil form (some few even of these), that we are able to speak of these as forming characteristic features of the old Silurian thickets. Doubtless man}- other forms of vegetable life existed, whose traces have long since entirely disappeared. The wonder is, considering the immense remoteness of Silurian time, that any trace whatsoever, either of animal or vegetable life, should have reiched our time. ^lost strange is it to think that even of the denizens of those ancient thickets some traces have been found. Be mains of scorpions were discovered in the Silurian locks of Sweden, Scotland, and the United States almost simul- taneously in 1884; while in those of France, also in 1884, the remains of an ancient cockroach were found. Where scorpions and cockroaches abounded, not only must there have been many other forms of land animals, but animal life must have exi.sted on land during hundreds of thousands of years. For the laws of biological evolution do not permit us to believe in the development of living creatures so com- plicated in structure as the Arachmdcp and the Jllnffiihc, save in vast periods of time. In these early stages of paljeozoic time we find evidence not only of multitudinous life, but of many forms of life. StUl within the Silurian era we find vertebrate forms in fishes akin to the modern sharks, the sturgeon, and the gar- pike. (Tie catfish shares with the cockroach the honour of descent from Silurian times.) Onward through Devonian time vertebrate life presents itself still only among fishes, but now in ever increasing variety and numbsrs. New forms of crustaceans — the Eurypterids — having affinities also with the Arachnids? (scorpions), began to replace the trilobites, from which probably they had descended, though after transformations requiring vast periods of time. Many other forms of life existed also throughout the Devonian period, while an abundant vegetation spread over the land, traces of no fewer than a hundred diflerent species of plants having been discovered in the Old Bed Sandstone. True conifers now began to appear, or at least fossil races of such trees are for the first time recognissd in Devonian rocks. The forests must have been uniformly green, for millions of years were to pass before deciduous trees were to appear. Many forms of insect life existed in those overgreen forests ; fossil wings of insects have been found which seem even to indicate by their size an exceptional wealth of insect life ; for races attain large size only under favour.ible conditions. Thus among several forms of May Fly we find one whose wings must have had a spread of fully five inches ! Strange, be it noted in passing, to find traces thus ancient certainly not less than 20,000,000 of years old, of a creature whose very name— the ^y)/(p»iwo>i natui-alists call it — means the creature of an hour, so short is its actual life, so slight its seeming hold upon existence. But now for the purpose of the sketch here planned we need no longer consider the details of the progress and development of life. We have thus far considered these because they serve to show how far back, lieyoud the time even when the oldest rocks were forming, we must throw the beginning of life upon our earth. But so soon as we have recognised this, so soon as we have understood that periods to be measured by hundreds of thousand.?, if not by millions of years, must have passed while the fauna and flora of even the Silurian rocks were being developed, we can pass onwards over stage after stage of the earth's life, noting how during every stage multitudinous forms of animal and \-egetable life existed. Some forms were as yet in the first stages of development, others fully formed, others highly developed, and others already approaching the time when, having outlasted their proper era, they were about to disappear. In disappearing they left the field open to kindred races not descended from them hut from the same progenitors, having, however, been saved from extinction by such changes as fitted them for their en- vironment. In this sense one may compare the various forms of life, animal and vegetable, to the various individual representa- tives of that form, among whom we recognise at one and the same time the infant, the young, the middle-aged, the old, and those nearing death. For species and genera as well as iniUviduals have their inception, their growth, their full vigour, theii' decay, and finally their death ; though because the pei-iods of time necessary for the full develop- ment and the eventual decay of a race are so long that the lifetime of an individual (even of a longer-lasting type) is usually but a second by comiiarison, we are apt to imagine permanence where in reality there is only relatively long- lasting development and dissolution. It has been because of this that men have so long been led to imagine that races of plants and animals can be neither developed nor destroyed, that all races must have had their beginning in a process of direct creation, and can only have their ending through a proce.--"S of catastrophic destruction. Even when geologists began to recognise the enormous duration not only of the so-called primary, November 1, 1887.] ♦ KNOWLEDGE ♦ secondary, aiul tertiary eras, but of the different systems included in each, they still supposed that the fauna and tioi-a of one era were destro_ved before another era began, those of the new era being specially created. At length, however, the great law of biological evolution was discovered, which shows how genera, species, and varieties undergo modifications fitting them for theii- sur- roundings, modifications individually small but eventually capable of changing [irlien necessari/'^ ) the whole character of the plant or animal so developing — those races which do not duly develop when change is required eventually dj'ing out. Then science began to see that neither creation nor catas- trophe is required to explain the life-histoi'y of the earth. Precisely as the geologist sees in processes such as are taking place now the explanation of all those features of the earth, ocean and continent, mountain range and river channel, hills and valleys, ravines and chasms, which in old times had been explained by processes of catastrophic in- tensity of action, so now the biologist recognises in all the forms of vegetable and animal life, infinitely varied though they are, the product of processes of biological evolution such as we can see in action at this present time, though possibly in the lifetime of a man, or even of a race of men, they may produce scarce discernible changes. (To be continued.) COLLISIONS AT SEA. By Gilbert R. Faith. ACTION OF THE RUDDER UPON STEAM AND SAILINO VESSELS. ANY years ago I had occasion to make a voyage from Halifax, N.S., to Bermuda. The vessel was the Cunarder Merlin, and her commander the '' commodore " of the Ber- muda, West Indian, and Newfoundland line. We left the pier about midnight, and a very dirty night it was. Something very like a gale from E.N.E. was blowing, with fitful storms of rain. We made a good stait, however, and in an hoiu- and a half had steamed past Sambro' light, some twelve or fourteen miles from Halifax, and the danjrerous stony-hearted group " The Sisters," with whom mariners care not to have even a bowing acquaintance (no pun intended), wei'e holding their storm-revels not fiir way. From the time of leaving the wharf I had remained in shelter from the rain under the main companion, smoking and enjoying the scene, if scene could be called what was dimly visible on so dark a night. Suddenly a rush of feet on deck, an excited outcry, and then a tremendous crash on our .starboard side. Simultaneously an immense white spectral object loomed high above us, and instantly vanished astern into the darkness, while down upon the stout hatch- way, the half dome beneath which I stood, rattled blocks and broken rigging. It was the work of a moment to jump on deck, and of little more to kick off my boots, for I thought from the shock that we must founder, and was *I emphasize this because some opponents of the doctrine of evolution imagine they have fully met the arguments of the believers in e\'olution, when they have shown that in some cases races have remained unclianged for thousands of years. This may happen — aye, and much longer periods of changelessness — where the con- ditions have not changed. The Cattish has outlasted tens of thou- sands of races wortliier, it might have seemed, of long continuance. determined to make as good a fight of it as possible. A glance round showed that the starboard bulwarks had been swept away from aljout amidships, and with them boats and a deckhou.se, while the starboard stays of the smoke-stack had disappeared, and the main and mizzen shrouds and backstays swung in against the masts. Some minutes passed before I was able to get a word with one of the junior oflicers, when I learnt that the ship had not sus- tained any serious damage, and that the injuries she had received were all above board. " What was it that struck us?" I asked. He replied, "A large square rigged vessel; she bore down straight upon us under as much sail as she could carry; the beggar carried no lights; but just as we struck, I saw a fellow jump into the bows with a lantern." After I had with some difliculty recovered my discarded boots in the darkness, I walked aft on to the quarter-deck and found the captain near the wheel. "A pretty close shave that, Captain S.," I said. " Yes," he answered quietly and seriously, " hut if I Jmd followed the sailimj instruc- tions ive should not he here now to talk about it." It was not my province to ask him to explain, but I felt that at a critical moment his thorough seamanship had inspired him to do something which contravened oflicia] orders for such emergencies, but had saved our fives. I have since been enabled to form an opinion as to what the gallant little captain did do, and proceed to relate another incident, which will perhaps enable the reader, if interested, to do so too. Several years after the adventure narrated above I was standing on the pier at Halifax seeing oft' some friends on the Cunarder Alpha. As the steamer shot out into the stream a friend who stood near me (a shipowner himself, much interested in matters of navigation, and a keen obiserver to boot) remarked, "G , what course will that steamer take when her helm is put a-port?" I answered, " Why, surely there can be no doubt about it : her heacl will come round in the other direction." " No, it will not," he said. " Her course will be very soon changed to that direction ; but you will find that it is the stern of the vessel which will be deflected to the left, and not the bow which moves round in the direction you suppose. Now take a line along that ship to the white house on the opposite shore, and note the movement." I did so ; and surrendered my opinion at once, for he was right. The following diagrams will illustrate my observation : — No. 1 is the fine No. 1. which I was confident the ship would follow ; No. 2 suggests the deflection which I actually saw. Now my preconceived idea of the movement of a vessel when the helm is put up or down is, so far as my observa- tion goes, the universal belief. If this is so, what a fruitful .source of collisions 1 In the hope of eliciting a discussion which may throw light upon this important matter and lead to beneficial results, I have written the present article. ♦ KNOWLEDGE ♦ [November 1, 1887 Some ten years ago (if my memory serves) occurred the disastious collision between the Grosser Kurfiirst and the KiJnig Wilhelin. The focts of this catastrophe prove, as it seems to me, the principle above stated, and the ignorance of the commanding officers in regard to it. The two vessels in question had in the course of manoeuvring got into dan- gerous proximity while steaming parallel to each other, and orders were given to sheer off and separate, the belief being that, if one helm were put down and the other up, the vessels would diverge in regular curves. What actually occurred was that the sterns of the two vessels approached each other until the collision occurred, which resulted in the sinking of the weaker vessel, and the drowning of the greater part of her crew. In the mquiry wliich was made into the cause of this disaster the officers of both ships were pronounced free of blame, and it was determined to institute a course of experiments to ascertain how the vessels could have come into contact while efforts were being made to separate them. I have never heard what the result of the experiments was, and do not think that it was pub- lished. To illustrate by a diagram. No. I represents the intended No. 1. No. 2. course of the two ships when separating ; No. 2 represents their actual course. Not long after the preceding catastrophe occurred the following collision, which must be well remembered. Two Sound (Long Island Sound, U.S.A.) steamers of the same line, the Stonwgton and Narragansett, were proceeding to their destinations. They had been accustomed to pass each other midway of the route for years, but on this occasion they proved to be approaching each other too directly. The rule of the road was followed on this occasion. Each vessel obeyed the sailing instructions, as was afterwards admitted. If these were adapted to such cases the vessels should have cleared each other. But they were approaching head-on with great speed ; there was not sufficient interval to allow for the stern deflection, and they were brought into collision with such violence that one sank with the loss of many lives. The newspapers commented upon this collision as inexplicable because the sunk steamer was struck upon the reverse side to what would have been expected, which fact is easily explained upon my hypothesis. It was, I believe, by ordering the helms of the Merlin in a sense directly opposed to the published instructions that Captain S. so deflected the after part of his ship in the few moments allowed to him as to receive a glancing instead of a direct blow. As a last illustration, I will instance the loss of the fine steamer Oregon. The facts in this case are unfortunately not very clearly known, but it is generally admitted that she was sunk by a vessel apjiroaching her obliquely from the port side, which in the fog had got too near to be avoided. It seems to me possible that the collision was owing again to the following of sailing directions, based upon ignorance of the principle I am seeking to establish. Diagram No. 1 No. 1. No. 2. shows my idea of what actually happened. No. 2 what might have happened if the instructions had been directly dis- obeyed ; had the vessels then struck, it would have been a glancing blow, which would not have seriously injured the steamer. It is to be hoped that a series of experiments as to the amount of this deflection and its relation to the length, draught, and speed of the vessel might result (if it is not presumptuous in a landsman to say so) in a modification of the sailing instructions for such critical cases as I have above instanced, as may avert collisions arising from similar causes in the future. Since a conversation on this subject here incited by the accounts of two quite recent collisions of English ironclads, a friend informs me that he has observed a steamboat leaving a wharf in Toronto Bay, which he carefully lined by means of a stationary object on the island opposite. The boat was steaming directly away from him at five or six knots, when the helm was ported, and he saw that the whole vessel was deflected to the left side of the line on which she had been travelling, and that it was some seconds after the helm had been ported before her bows crossed that line. Thus : — November 1, 1887.] ♦ KNOWLEDGE ♦ WATCHED BY THE DEAD.* X an essay on "A Novelist's Favourite Theme," t the present writer has shown that in all Dickens's novels except "Oliver Twist" (''Pick- wick " was not a novel), he presented the jucture of a villain or a hypocrite, watched by one whom he despised or regarded lis;;htly, b'lt by whom be was eventually brought to justice. We might even have included " Oliver Twist," if it be considered how little either Sikes or Fagin suspect the watch by which Nancy defeats the projects of the craftier villain and of his dupe Monks. However, the theme is so repeatedly worked into the plots of Dickens's chief works that it was hardly necessary to note a slighter use of it such as this, except by way of showing that the whole series of stories, long and short, is thus accounted for. No one can doubt, we think, after he has examined all the evidence collected in the mentioned essay, that there was something enthralling for Dickens in this thought of a steadfast watch by an unseen or unnoted enemy, a constant danger lurking where no danger at all was suspected. It will have been noticed further, by those who followed us through the survey of Dickens's works in search for this theme, that repeated reference was made to the use of Dickens's favourite idea in his last, but unfinished, work. There, it seems to us, the theme was to have been introduced in its most striking form, in that form which Dickens himself had mentioned in '• Martin Chuzzlewit " as most terrible to think of. Dickens had pictured in his latest completed novel a man supposed to be murdered, but really alive, and watching the ajssociates of the dead murderer of the man mistaken for him ; and therein he had come very near to the idea he had pictured as the most terrible of all forms of his favourite theme. How he had enjoyed this embodiment of his theme one sees in reading the scene where the inspector proposes to arrest Harmon as an accessory in his own sup- posed murder. Of all the strange experiences Mr. Inspector had had, that he admits was the strangest. It had for him, Dickens tells us, all the interest of a clever conundrum, the answer to which he had been utterly unable to guess, and, " giving it up," had been told. Here Dickens had come as near as he had till then found it possible to come to the supreme horror — that the dead should confront his mur- derer— not onlv (as in " Our Mutual Friend ") some man supposed to be murdered should confront the associates of the supposeil murderer, nor even that a mau supposed to be dead should confront a murderer, but that a man supposed to be murdered should keep untiring watch upon the man who supposed himself the murderer. Running through our former essay will be found the idea that this supreme horror was to have been wrought into the plot of Dickens's last novel, and that there is sufficient evidence in the work even in its incomplete state to show this. We propose now, not to examine the story in detail in regard to the mystery of Edwin Drood's fate, which would occupy much more space than could here be sjiared, but to touch on certain features of the story which have hitherto been little noticed, if they have been noticed at all, and to consider certain general principles in regard to the interpre- tation of mysteries such as those involved in this fine un- finished novel. First, the author's idiosyncrasies must in all such cases be considered very carefully. Some novelists like to disclose the meaning of the events described earl}' in a story, so as * This article, tinder the title " Aftermath," forms the last chapter of a little book presently to be pabli.shed by Messrs. W. H. Allen & Co., under the title " Watched by the Dead." t Cornkill Magazine for March 1886. to leave the reader in no manner of doubt as to the real position of affairs. Thackeray had few secrets from his readers ; and accordingly the story which he left unfinished leaves no more doubt as to the ending than if it had been completed and the reader had turned to the last chapter before he had reached the end of the first volume. Dickens's method was difierent. He always left his readers — even the keenest — in doubt as to the actual interpretation of mys- terious matters introduced early in the story, and as to the precise way in which the story was to end. But he was careful, nevertheless, to introduce a number of little details which were afterwards found to have been significant even on these points, and to have been quite clear for clear- sighted readers on some matters which the duller readers supposed to be mysterious. For instance, while I suppose no one guesses up to the last chapter of " Little Dorrit " the nature of the plot in which Eigaud-Blandois, Flintwinch, and Mrs. Clennam were concerned, or the v.^ay in which the story is to end, yet every one of any keenness knows that the old house is to fall before the story ends. Dickens not only made that clear, he meant to make it clear. By a curious accident, the fall of a house excited a great deal of attention a few days before the last section of " Little Dorrit " appeared, and sevenxl newspaper critics asserted that Dickens had cleverly availed himself of the interest in that catastrophe to add an effective scene to his novel. He pointed out, however, that he had been at the pains again and again to describe the premonitions of the coming fate of the old house. And every attentive reader had known that the house was doomed. We may faii-lv assume, then, that in like manner the de- tails of "'The Mystery of Edwin Drood " were concealed; and the actual end of the story was not revealed except to Miss Hogarth, and in part to Mr. Forster, while, nevertheless, the broader features of the mystery were not hidden from the keener class of readers, whose enjoyment of the story Dickens well knew would be enhanced by the i-ecognition of the general character of the plot. Dickens did, indeed, express to Miss Hogarth the fear that the Datchery assumption had been so handled in the last chapter (written) as to disclose too much ; but he could hardly have intended it to disclose nothing. No one knew better than he the zest with which those who really appreciated his work would enjoy the humour and pathos of this assumption. He would not have left his best readers to obtain this pleasure (the kind of pleasure which is most noteworthy in the reading of all his novels), from a second reading, after the plot was known, as with the duller readers of his stories was commonly the case. The keenest reader would have — or rather we must unfor- tunately say, the keenest reader has — quite enough to interest him in the way of unexplained mystery ; but the general interpretation of the " Datchery assumption " cannot be mistaken by any who have really studied Dickens's ways. Albeit we may pause here for a moment to ask how far any novel, turning chiefly on a great mystery, might have been interpreted if the writer's pen had been dL'-.abled ere yet the work was completed. We have already done this "with one of Dickens's own works, and we may find another example in " Our Mutual Friend." Does any one from the beginning doubt that Julius Handford, .John Rokesmith, and John Harmon are one and the same person ? Can any one imagine that Dickens did not mean his readers to note the confusion of Handford under the inspector's questioning, and to see even at that early stage that the body found by Gaffer Hexham is not really John Harmon's. But if that point had been overlooked, a number of others would have been decisive that the whole plot of the story was to turn on the " Rokesmith assumption," and that John Rokesmith was no other than John Harmon. Mrs. Boflin's sudden ♦ KNO^VLEDGE ♦ [November 1, 1887. feeling that the child she had loved had been near hei", she knew not how ; Rokesniith's start when he heard the name of the adopted child (his own name) ; his remarks about John Harmon : these all obviously show who he is, and Dickens meant them to be so understood. We have no doubt he meant the identity of Datchery to be similarly recognised by those who knew his method. (Of course, we have verv decisive evidence in regard to " Our Mutual Friend " that Dickens did not care to make any mystery of the Ilokesmitli assumption ; for long before the end of the story we find Rokesmith talking about the details of the events which had attended his disappearance from among living men. There is no reason to suppose that he intended to be at all more eai-eful about the identity' of Datchery — a little later on though, perhaps, than the story actually reached.) But it may be well to consider, in passing, two other stories, each turning in marked degree on a mystery — viz. " By Pi-oxy " and " The Moonstone." The former novel admirably illustrates our subject. For although the plot is about as unlike that of " Edwin Drood " as any plot could well be, we have in " By Proxy " a man supposed to be dead, watch- ing the man who is guilty of worse than murder — seeing that he has withheld the price at which he had, as he believes, bought his own life at the cost of a better one. Now in " By Proxy " it is essential to the interest of the latter part of the story that the reader shall not be able to conceive how Conway can have been saved, while yet he shall feel that Conway must be alive. Accordingly we have not the slightest direct suggestion of Conway's escape from death, except in the rush of a hasty messenger past the flying wretch Conway had saved. Yet we know that somehow Conway's escape has been achieved ; and at a stage of the story corresponding to that which " The Mystery of Edwin Drood " had reached when the pen fell from the author's hand we have decisive evidence that Conway lives ; nor does any one fail to understand the assumption by which he is enabled to meet his daughter without announcing his escape to the man for whom he has designed a fearful punish- ment. The mystery in " The Moonstone " is altogether different in character, yet equally serves to illustrate our argument ; because in " The Moonstone," as in " By Proxy," "Edwin Drood," and " Our Slutual Friend," the chief interest of the plot (we do not say of the novel as a whole, be it understood) turns on the solution of the mystery. It is noteworthy that, while in the other stories the reader is left in little doubt as to the general solution of the mystery, though altogether doubtful as to details, in " Edwin Drood " and " The Moonstone " even the general meaning of the events de- scribed in the earlier pages is left in doubt, at least for all except the very keenest readers. There are touches in the chapters of " Edwin Drood " preceding Edwin's disappear- ance which show any one who understands Dickens's manner, and has an ear for the music of his words, that Edwin Drood is not actually to be killed, and that the Drood who really is to be seen no more is the light-hearted whimsical boy of the earlier pages. But that evidence was not for all readers. It may even be doubted whether Dickens himself knew how clearly he had disclosed Edwin's real fate fur those who knew his voice, any more th:in many of us know how full of meaning are certain tones of our voice for those who know us well. Nor can one analyse the effect of such tones in a written story any more than in the speaking voice. In reading " Edwin Drood," we (who write these lines) never felt any doubt from the first page to the last that Drood was to be one of the living character's at the close of the story. Yet we could not have given any definite reason for the faith that was in us, until at least the scene where Grewgims tells Jasper that Edwin and Rose had cancelled their plighted troth. In " The Moonstone " no one, we should imagine, has an}' idea as to the real solution, numerous though the facts are which that solution, and that alone, is to explain. There arises a vague suspicion, as we read about Frank's smoking, his sleeplessness, the difference with the doctor, and afterwards that Frank had slept well on the night of the robbery, that these little details are significant. I'osKihli/, if the story had been left unfinished, the same kind of analysis which we have ourselves given to " The Mystery of Edwin Drood " might have led to these points being so carefully considered and put together as to disclose the general nature of the interpretation of the Moonstone mystery — so much, for instance, as flits, that Frank had himself removed the diamond when under the influence of opium, that somehow Ablewhite had got hold of it, and that in some way unknown Miss Verinder was certain Frank had taken it from her cabinet. This would have explained the position of affairs at the close of the first part of the story, and one can imagine no other explanation consistent with our certainty that Frank has not wittingly had any part in abstracting the diamond, that ]\liss Verinder is quite incapable of the trick attributed to her by the detective (really keen though he is shown to be), and that Ablewhite has in some way got the diamond into his hands. The details of the disappearance, however, and of course the singularly effective clearing up of the mystery in this fine story (in our opinion far the strongest of all Mr. Collins's novels), could never have been guessed, no matter how close an examination any reader might have given to the earlier part of the story. Yet even these details are suggested when as yet the end of the story is far off. {To he continued.) COAL. By W. Mattieu Williams. N my paper preceding this I described the general nature and magnitude of the problem of colliery ventilation. I will now endeavour to render intelligible the methods of ventila- tion that are actually adopted, omitting, for reasons already stated, any account of air- ])unips, blowing machines, fans, and other devices for mechanical ventilation, and confining myself to the principle explained in my last, which in this country is almost universally applied. This principle is simply the setting of air in motion by its own gravitation by connecting two columns of air of different weights in such wise that the heavier shall descend and the lighter rise in nearly the same manner as do unequally weighted scale- pans. As it is easier to diminish the density of a given column of air than to increase it, especially where fuel is abundant and cheap, the work of differentiation is carried out by operating on the upcast rather than the downcast shaft. We have simply to raise the mean temperature of one shaft above that of the other, and the required movement is started. The air falls in the cooler and rises in the hotter, forcing its way from the cooler to the hotter through such intervening passages as may connect them. These two shafts may be only a few yards distant from each other, and yet the current of air may be so tortured that it shall travel some miles in passing between. The diagram shows how this is done. D represents, in horizontal section, the downcast shaft, U the upcast shaft, a, b, c, and d are passages or cross i-oads with doors. It is November 1, 1887.] ♦ KNOW^LEDGE ♦ evident that if the door at a is opened, the air will pass directly by the course DreU, as it will take the shortest course open to it. If a is closed and h open, its couree will be D6U ; if a and h are closed, and c is open, the course will be DcU ; if a. b, and c are closed, and <; open, the course will be DdU ; if all the doors are closed, the air must (neglecting the dotted line at present) take the long journey DeJJ. In practice, of course, the arrangements are much more complex, but the principle is the same. It is easy to under- stand that by skilful arrangements of this kind the air may be made to take any longer or shorter course that may be desired, according to the plan of the pit roads and workings. But supposing a thoroughfare is required, as continually happens, through a passage that must be closed to divert the ventilation — that coal has to be run through the pas- sage a while the air current must pass through e, what must be done 1 This problem is solved very simply. In- stead of a single door as marked in the diagram, two doors or " stoppings " are used at sufficient distance apart to allow a tub or train of tubs to stand clear between them with space to spare. The coal enters one door, this door is then sluit, and it proceeds to the other. So far I have only taken the case of continuous passages or roads, but it commonly happens that a working while in progress has no outlet at the working end — is a cul de sac. If the extreme distance of this from the road is but moderate and the coal is not exceptionally fiery, the current of air crossing the mouth of the working produces a ^tir, which, together with the natural diffusive action of gases, supplies sufficient ventilation ; but when there is danger of accumu- lation of fire-damp in the working, a brattice is u?ed, as shown by the dotted line at / in the diagram. This brattice, whiuh is simply a partition of wood or of " brattice cloth," efl'ects a further diversion of the current, compelling it to sweep round to the limit of the working at y and clear out the dangerous gases that would otherwise accumulate there until, with a limited supply of air, they formed an explosive mixture. These brattice -walls are made by simply erecting upright posts from floor to roof, and nailing the brattice- boards and cloth to them, and carefully fitting to roof and floor. Much care, of course, is required in the working of the doors in a large pit where they are numerous and complex. A small amount of leakage from each would, of course, retard or stop the current at the extreme limits of its course. The friction of a long journey effects considerable re- tardation and practically limits the distance through which the air may be forced to travel. Besides this there is another limitation. As the ventilating current proceeds it picks up the inflammable gas and the carbonic acid expired by the miners. It may even render dangerous those parts of the mine that would be otherwise safe by carrying gas from dangerous localities. Therefore in extensive collieries a system of splits is adopted. This will be understood by again referring to the diagram, where, instead of all the air making the long journey DeU, it may be split into four independent currents, one travelling by the course D&U, the second by DcU, the third by Di/IT, and the fourth by DeU. But how can this be done 1 It is simply a matter of balancing resistances. Other conditions being equal, the resistance vai-ies with the length of the journey ; therefore, if resistances be respectively placed at b, c, and d, which shall be just equal to the addi- tional resistance due to increased length of journey in getting round by e, the current of air will divide itself accordingly. This may be carried out by making a small opening at b, a somewhat larger opening at c, and still larger at d, while e remains fully open. In order that all the air shall rush through the diminished opening at b, it must do so at an increased velocity, and this involves in- creased resistance, which varies directly with the length of the journey and inversely with the sectional area of the opening. This balancing of resistance requires skilful management and the aid of regulators to vary the size of the openings as required. In some of the great collieries as much as 300,000 cubic feet of air is passed per minute through all the complications of the roads and workings. As already stated, the power for setting all this air in motion is obtained by heating the air of the upcast shaft. Formerly a stack was built over the pit, and this was heated by a furnace on the surflice. In small shafts a fire was suspended in the shaft, but these are now superseded in large workings by an underground furnace connected with the shaft by an upsloping flue which discharges all the heated products of combustion into the upcast shaft, which is thus converted into a great chimney, the contents of which may be heated to 80° or 100° above the air in the downcast shaft; l-tO" to 160° being temperatures commonly obtained in the upcast shaft. The furnace used for heating is one with a large hearth and thin fire, frequently fed with small coal ; the width of the fire may be .5 to 10 feet, and the fire-bars as much as 6 feet long. Thus a large area of air is heated at once. A few figures will show the power that may thus be obtained in a deep mine such as that of Ashton Moss, which has a depth of 2,850 feet. Let us suppo.«e the diameter of the shafts to be 12 feet each ; their sectional area will be about 113 square feet, and thus each will contain 113 cubic feet of air for every foot of depth. A cubic foot of air at 60° weighs 1-29 oz. avoirdupois; .-. 113 cubic feet weigh 92 lbs., and the total column of air at 60°= 2,850 X 9-2, which, in round numbers, amounts to 26,000 lbs. But in heating air from 60' to 150°, it expands one-sixth of its bulk ; therefore the hot air in the upcast shaft, in such a case, will weigh one-sixth less than the cool in the downcast. This difference amounts to -l:,333 lbs. Thus the vis a tergo, or force driving the air through the roads and workings and up the upcast shaft, will, in this case, exceed a pressure of 4,000 lbs. It would 8 ♦ KNO^ATLEDGE ♦ [November 1, 1887. exert tbat amount of pressure against any unyielding resistance. , , <- • i From this it will be understood bo«' a g.ile of wind may be made to blow along the dark subterranean roads of a deep coal-pit. I may add that the figures above rather under-estimate the actual force, as I have taken the air at surface density. It actually increases as we descend— increasing, of course, all the quantities named. THE ONE-SCALE ATLAS. Map IX. by-Ric3i4 A.Proctor .

N considering such a cliart of stars as appeared in the number of Knowledge for May 1886, considerations of singular, one might almost say quaint, significance are suggested to the mind. Among all those discs representing stars, and each telling the same wonderful and complex story, no two represent the same time. The story told by that star-chart is not simultaneous. It bears the same relation to a record presenting matters as they actually are at a given moment that a story told by a news- paper bears to a chapter in ;i volume of history. When we are looking at one star-disc, we contemplate the self told record of a suu as that sun was many years ago ; when we turn to another sbir-disc, we see a similar record, also relating to a long past epoch, but not to the same epoch. One of the star-discs, regarding it as in a sense a portrait of a remote sun, may be hundreds of years older than another, though both were taken at the same instant on the photo- graphic plate. Pi-obably within the range of this one picture, with its two thousand stars, we have records extending over many hundreds of years. It is true that the picture represents a rich region of the Milky Way, and my own theory of the Milky Way, adopted and supported by such independent thinkers as Herbert Spencer * in England, and Oscar Peschule in Germany, recognises the whole rich galactic mass like that seen in Cygnus as in reality what it appears to be (that is, as truly a stellar cloud, whose farthest portions are not relatively much farther from us than the nearest). Yet it can hardly be but that in the same field of view are seen many stars which do not belong to that cloud, but shine from beyond depths far more remote. Even as regards the great star-cloud itself, moreover, we have a wide range of time to deal with. Judging from the length and width of the great clustering aggregation of the Milky Way in Cygnus, from the heart of which the chart has been taken, we may infer a depth corresponding to more than one-tenth of the distance of the .star-cloud regarded as a whole. Supposing this distance, then, to correspond to a light- iourney of one hundred years — a very moderate assumption when we remember that Sirius lies at a distance of about twenty years' light-journey from us — we find that the farthest stars of the cluster tell us their story ten years after the nearest stars. Thus the strange thought arises that while the chart does not represent the actual state of the pictured stars at the moment when the photograph was taken, it does not even represent the state of those stars — either as to relative position or relative lustre — at any epoch whatsoever. For aught we can tell any star taken at random in the chait may have been extinct many years before it painted its record on the photogi-aphic plate ; or it may at the moment when its light reached us have been in reality very much brighter or very much fainter than its pictured record would seem to show. Stars may in the meantime have shone forth which are not shown in the chart, because the extremities of the light-pencils by which alone their discs could hi delineated had not reached within many thousands of millions of miles of our solar system. Then, again, not a single star in the whole chart is shown in its true * As regards important portions of my theory of the universe I was anticipated by Mr. Herbert Spencer — though I only learned this long after I had advanced that theory. But I am speaking above of the Milky Way regarded as a congeries of stars, iu which aspect I believe I may say that I alone established those details in which my theory differs from that of the Hersohels formerly accepted. position, and no two stars are shown in their proper rela- tive position. For every star of the two thousand travel- ling along through space must have some thwart motion, greater or less (we may exclude as impossible the case of a star moving e.ractli/ towards the solar system) ; and no two stars can have exactly the same thwart motion. Hence have we this strange result, that a photographic record which the astronomer justly regards as a most marvellously exact star-chart, far more exact than any such record as the most skilful astronomers can obtain observa- tionally, nevertheless neither represents what is now, or what ever was — precisely as here shown — at any moment of time. MAGIC SQUARES. By W. Holden-. ?s I have not been hitherto " A Constant Reader of your valuable Periodical," I do not know if you have dealt with the sub- ject of " Magic Squares " or not ; but I have thought that the enclosed would be interesting to your readers. They appear to me to be marvels of ingenuity. About fifteen years ago the methods of construct- ing these " Magic Squares," so called, was discussed in " The Riddler " columns of the Addnkh Observer, of which columns I have the editing. It appears that the rules for constructing squares, of which the root is an odd number as 7 X 7, is very simple. Thus 1 have in my possession a square il X 27, containing all the numbers from 1 to 27^, and of course the sum of every horizontal, vertical, and ,. , r • 1- 27- -f 1 diagonal line is 2/ x - = 9.855. But the method of constrttctiug it is so simple that the figures may be written down consecutively without the slightest hesitation. The case, however, is very difierent when the root is an even number, and especially so when it is the double of a prime number as 14 x 14. But at the time to which I refer, Mr. E. J. C'atlow, who was then engaged as a shepherd in the interior of this " island continent," turned his attention to the subject, and discovered the rules for constructing .squares of every kind, no matter how large. He subse- quently told me that if he had not turned his attention to the subject, and to the German language, his occupation was so monotonous, and the solitude so profound, that he feared he would have gone insane. Some time after his discovery of the rules referred to. Ml-. Catlow wrote a paper describing thtm, and sent it to Mr. C. Todd, C.M.G., our Postmaster-General and Govern- ment Astronomer. The paper was read by Mr. Todd before the Adelaide Philosophical Society, and he stated that in all his mathematical studies he had never met with any rules of the kind app'icable to all numbers. Curiously enough, however, while Mr. Catlow was study- ing the suViject in the far north, Mr. J. B. Bassett, a school- master of Willunga, thirty miles south of Adelaide, was doing the same thing, and the result was the discussion in the Adelaide Observer as to priority of discovery, to which I have referred. Mr. Catlow and Mr. Bassett have both •' joined the great majority," but among the papers of the latter was the square of which No. 1 is a copy. You will observe * Although iu the earlier volumes of Knowledge we had a great number (some said too large a number) of magic squares, and have in MS. snlutions of the still more complex pu;;zles presented by magic cubes, we print Mr. Holden's paper unhesitatingly, as presenting novel and interesting developments.

I have iailed in my attempts to discover the rules for the construction of No. 2. Mr. Campion is a storekeeper. He was in Adelaide about a month ago, and he informed me that he discovered at the beginning of the present year the rules for constructing all such squares. In proof of this, he has since then sent me a " Jubilee Magic Square," 50 X 50. It covers a sheet of paper about four feet square, and is perfect in every lespect. Thus the sum of each column of the outer square is 62,525, with a constant subtrahend of 2,501 on approaching the centre. The sub- joined was published in " The Riddler " a few weeks ago : — - Mr. W.

NOTE ON EUCLID (I. 32). (Prop. 3, Bk. I.; Axio.m 12, Bk. I.; and Parallels). \ COERESPONDENT asks whether Euclid I. 32 cannot be proved by mechanical con- .siderations independently of axiom 12. It has always seemed to me that the pro- position is self-evident, the mind at once picturing some such angular measurement as is .shown in fig. 1. The arrowed rod pq, pivoting round A to position jiq, measures the angle A ; then, pivoting round p, to position p'q', mea^-ures the angle n ; Fig. 1. and lastly, pivoting round c to position p'q', measures the angle c. It has manifestly pivoted through two right 12 ♦ KNOW^LEDGE ♦ [November 1, 1887. angles, lying now in the same direction as at first, with changed ends. Hence the three angles, which are together equal to the angle through which the rod has pivoted in all, amount together to two right angles. With regard to axiom 12, and the treatment of the whole subject of parallelism and non-parallelism in Euclid, the trouble seems to arise from two causes : First, the use of a negative definition of parallel lines, instead of a positive definition from which the negative property could be deduced ; and secondly, from the wish to prove certain matters really axiomatic — for instance, that opposite or vertical angles are equal. The axiomatic ideas underlying axiom 12, which .as presented in Euclid (with its converse, Euc. I. 16, as a jyroposltion and in company with pro- positiuns relating to parallels) is not axiomatic at all, may be thus dealt with : — If the straight lines ab, de, crossing in c, be supposed shifted so that the point c falls at c. in ab, ab remaining unchanged in position, and de falling into the position fgh, FH can nowhere cut de. For any argument showing that GF produced towards f would cut cd produced towards d. would equally show that ce produced towards e would cut GH produced towards h. And if both intersections occurred, the two straight lines de and fh produced far enough would enclose a space. This, however, is not axiomatic, unless we take it for granted that the angle fgb, which (we see from the way in which it was obtained) is the same as the angle dcb, is equal to cgii, which (for a like reason) is the same as the angle ace ; for the obviousness of the argument depends on the fact that we have the same arrangement precisely when we look at the figure as it stands that we have when we reverse it. Now it is not one whit more obvious that two straight lines will not enclose a space than it is that opposite angles are equal, or that two straight lines ca7i in any way be so drawn as never to meet. After it is seen that fgh obtained by moving acd to position agf will not cut dce, it ought to be equally obvious that any straight line q/ througli a on the side of gf towards d must cut CD, no matter how small the angle /gf may be. For the point _/' Ls some distance from gf, and by doubling of this distance will be doubled (this may be proved by superposition), and the doubled distance will in turn be doubled in the same way (by quadrupling g/'), and so on as long as we please : hence we must at length by successive doublings obtain a distance less than the dis- tance of any point in ED from fh ; in other words, c./ pro- duced far enough must pass to the side of ef remote from FH — that is, G/'will eventually cut ED. Or we may put the matter in the form of a general axiom, — Through a given point (g), outside a given straight line (dce), only one parallel can be drawn to that line. These properties, whether presented as axioms or reasoned out, serve all purposes. But in reality, if such matters are to be reasoned out, then the statement that two straight lines cannot enclose a space should be reasoned out too ; and I do not envy any one vvho makes the attempt. In fact, it leads directly to the discussion of non-Euclidean geometry, a part — and a useless part — of Dream INIathe- matics. Of the following three propositions, winch, dealt with as a subject for reasoning, would be the more difficult 1 — First, Through a given poitit there cannot be drawn a straight line in the same plane as another straight line, irhich, being jn'odiioed sufficiently far both ways, shall meet the latter straight line on both sides of the given point.

A FIVE-FOLD COMET. HE figure illustrating this article is taken from L'Astronornie, and represents the re- markable Southern Comet of January last, as drawn on successive days by Mr. Finlay, of Cape Town. The comet was first seen by a farmer and a fisherman of Blauwberg, near Cape Town, on the night of January 18-19. The same night it was seen at the Cordoba Observatory by M. Thome. On the next night Mr. Todd discovered it indejiendently at the Adelaide Observatory, and watched it till the 27th. On the 22nd Mr. Finlay detected the comet, and was able to watch it till the 29th. At Rio de Janeiro M. Cruls observed it from the 23rd to the 2.5th ; and at Windsor, New South Wales, Mr. Tebbutt observed the comet on the 2sth and 30th. Moonlight interfered with further observa- tions. The comet's appearance was remarkable. Its tail, long and straight, extended over an arc of 30 degrees, but there was no appreciable condensation which could be called the comet's head. The long train of light, described as nearly equal in brightness to the Magellanic clouds, seemed to be simply cut off at that end where in most comets a nucleus and coma are shown. This comet has helped to throw light on one of the most perplexing of all the ])uzzles which those most perplexing of all the heavenly bodies, comets, have presented to astronomers. In the year 1668^a comet was seen in the southern skies which attracted very little notice at the time, and would probably have been little thought of since had not attention been directed to it by the appearance and behaviour of certain comets seen during the last half-century. Visible for about three weeks, and discovered after it had already passed the point of its nearest approach to the sun, the comet of 1068 was not ob.served so satisfactorily that its orbit could be precisely determined. In fact, two entirely different oibits would satisfy the observations fairly, though one only could be regarded as satisfying them well. This orbit, however, was so remarkable that astronomers were led to prefer the other, less satisfacforj- though it was in explaining the observed motions of the comet. For the orbit which best explained the comet's movements carried the comet so close to the sun as actually to graze his visible surface. November 1, 1887.] ♦ KNO^A^LKDGE ♦ 13 Moreover there was this remarkable, and, indeed, absolutely unique peculiarity about the orbit thus assigned : the comet (whose period of revolution was to be measured by hundreds of years) actually passed through the whole of that part of its course during which it was north of our earth's orbit plane in less than two hours and a half! though this part of its course is a half-circuit around the sun, so far as direction (not distance of travel) is concerned. That comet, when at its nearest to the .sun, was travelling at the rate of about 330 miles per second. It passed thi-ough regions near the sun's surface commonly supposed to be occupied liy atmosp'ieric tuattev. calculate the return of comets.) The comet of 1680, called Newton's, was the very first whose orbital motions were dealt with on the principles of Newtonian astronomy, and Halley's was the first whose periodic character was recognised. In 1843 another comet came up from the south, and presently returned thither. It was, indeed, only seen during its return, having, like the comet of l(i()8, bsen only discovered a day or two after perihelion passage. Astro- nomers soon began to notice a curious resemblance between the orbits of the two comets. Remembering the compara- tive roughness of the observations made in 1668, it may be The CoDstellatiou?, thougU'uunamed, can readily be identified, when it is noted that the Comet's course, as here presented, began in the constellation of the Crane. Now, had the comet been so far checked in its swift rush through tho.se regions as to lose one-thonsandth part of its velocity, it would have returned in less than a year. But the way in which the comet retreated showed that nothing of this sort was to be expected. I am not aware, indeed, that any anticipations were ever suggested in regard to the return of the comet of 1668 to our neighbourhood. It was not till the time of Halley's comet, 16S2, that modern astronomy began to consider the question of the possiljly periodic character of cometic motions with attention. (For my own part, I reject as altogether improbable the state- ment of Seneca that the ancient Chaldean astronomers could said that the two comets moved in the same orbit, so far as could be judged from observation. The comet of 1843 came along a path inclined at apparently the same angle to the earth's orbit-plane, crossed that plane ascendingly at appre- ciably the same point, swept round in about two hours and a half that part of its angular circuit which lay north of the earth's orbit-plane, and crossing that plane descendingly at the same point as the comet of 1668, passed along appre- ciably the same course towards the southern stellar regions ! The close resemblance of two paths, each so strikingly remarkable in itself, could not well be regarded as a mere accidental coincidence. 14 ♦ KNOWLEDGE ♦ [November 1, 1887. However, at that time no very special attention was directed to the resemblance between the paths of the comets of 1843 and 1668. It was not regarded as anything very new or striking that a comet should return after making a wide excursion round the sun ; and those who noticed that the two comets really had traversed appreciably the same path around the immediate neighbourhood of the sun, simply concluded that the comet of 1008 had come back in 1843, after 175 years, and not necessarily for the first time. It must be noticed, however, before leaving this part of the record, that the comet of 1843 was suspected of be- having in a rather strange way when near the sun. For the tirst observation, made rather roughly, indeed, with a sextant, by a man who had no idea of the interest his obser- vation might afterwards have, could not be reconciled by mathematicians (including the well-known mathematician, Benjamin Pierce) with the movement of the comet as sub- sequently observed. It seemed as though when in the sun's neighbourhood the comet had undergone some disturbance, possibly internal, which had in slight degree affected its subsequent career. According to some calculations the comet of 1843 seemed to have a period of about thirty-five years, which accorded well with the idea that it was the comet of 1068, returned after five circuits. Nor was it deemed at all surprising that the comet, conspicuous though it is, had not been detected in 1713, 1748, 1783, and 1818, for its path would carry it where it would be very apt to escape notice except in the southern hemisphere, and even there it might quite readily be missed. The appearance of the comet of 1668 corre.-iponded well with that of the comet of 1843. Each was remarkable for its extremely long tail, and for the comparative insignificance of its head. In the northern skies, indeed, the comet of 1843 showed a very straight tail, and it is usually depicted in that way, whereas the comet of 1668 had a tail showing curvature. But pictures of the comet of 1843, as seen in the southern hemisphere, show it with a curved tail, and also the tail appeared forked towards the end during that part of the comet's career. However, the best observations, and the calculations based on them, seemed to show that the period of the comet of 1843 could not be less than 500 years. Astronomers were rather startled, therefore, when, in 1880, a comet appeared in the southern skies, which traversed appreciably the same course as the comets of 1668 and 1843. When I was in Australia, in 1880, a few months after the great comet had passed out of view, I met several persons who had seen both the comet of that year and the comet of 1843. They all agreed in .saying that the resemblance between the two comets was very close. Like the comet of 1843, that of 1880 had a singularly long tail, and both comets were remarkable for the smallness .and dimness of their heads. One observer told me that at times the head of the comet of 1880 could barely be discerned. Like the comets of 1665 and 1843, the comet of 1880 grazed close past the sun's surface. Like them it was but about two hours and a half north of the earth's orbit-plane. Had it only resembled the other two in these remarkable characteristics, the coincidence would have been remark- able. But of course the i-eal evidence by which the associa- tion between the comets was shown was of a more decisive kind. It was not in general character only but in details that the path of the comet of 1880 resembled those on which the other two comets had travelled. Its path had almost exactly the same slant to the earth's orbit-plane as theirs, crossed that plane ascendingly and descendingly at almost exactly the same points, and made its nearest approach to the sun at very nearly the same place. To the astronomer such evidence is decisive. Mr. Hind, the Superintendent of the " Nautical Almanac," and as sound and cautious a student of cometic astronomy as any man living, remarked so soon as the resemblance of these comets' 1 paths had been ascertained, that if it were merely accidental the case was most unusual; na}', it might be described as unique. And, be it noticed, he was referring onl}' to the resemblance between the comets of 1880 and 184.3. Had he recalled at the time the comet of 1668, and its closely similar orbit, he would have admitted that the double coincidence could not possibly be merely casual. But this was by no means the end of the matter. Indeed, thus far, although the circumstances were striking, there was nothing to prevent astronomers from interpreting them as other cases of coincident, or nearly coincident, cometic paths had been interpreted. Hind and others, mvself in- cluded, inferred that the comets of 1880, 1843, aiid 1668 were simph' one and the same comet, who.se return in 1880 probably followed the return in 1843 after a single revo- lution. In 1882, however, two years and a half after the appear- ance of the comet of 1880, another comet came up from the south, which followed in the sun's neighbourhood almost the same course as the comets of 1668, 1843, and 1880. The path it followed was not quite so close to those followed by the other three as these had been to each other, but yet was fai" too close to indicate possibly a mei'e casual resemblance ; on the contrary, the resemblance in regard to shape, slope, and those peculiarities which render this family of comets unique in the cometai-y system, was of tlie closest and most striking kind. Man}' will remember the startling ideas which were sug- gested by Professor Piazzi Smyth respecting the portentous significance of the comet of 1882. He regarded it as con- firming the great pyramid's teaching (according to the views of orthodox pyramidalists) respecting the approaching end of the Christian dispensation. It was seen under very remarkable circumstances, blazing close by the sun, within a fortnight or three weeks of the precise date which had been announced as marking that critical epoch in the his- tory of the earth. Moreover, even viewing the matter from a scientific stand- point. Professor vSmyth (who, outside his pyramidal para- doxes, is an asti'onomer of well-deserved repute) could recognise sufficient reason for regarding the comet as por- tentous. Many others, indeed, both in America and in Europe, shared his opinion in this respect. A very slight retardation of the course of the comet of 1880, during its passage close by the surface of the .sun, would have sufficed to alter its period of revolution from the thirty-seven years assigned on the supposition of its identity with the comet of 1843, to the two and a half j'ears indicated by its apparent return in 1882, and if this had occurred in 1880, a similar inter- ruption in 1882 would have caused its return in less than two and a half years. Thus, circling in an ever narrowing (or rather shortening) orbit, it would present!}', within a quarter of a century or so perhaps, have become so far entangled among the atmo- spheric matter around the sun, that it would have been unable to resist absolute absorption. What the conse- quences to the solar system might have been none ventured to suggest. Newton had expressed his belief that the effects of such absorption would be disastrous, but the phj'sicists of the nineteenth century, better acquainted with the laws associating heat and motion, were not so despondent. Only Professor Smyth seems to have felt assured (not being despondent but confident) that the comet portended, in a very decisive way, the beginning of the end. iSToVEMBER 1, 1887.] ♦ KNOW^LKDGE ♦ 15 However, we were all mistaken. The comet of 1882 retreated on such a coui'se, and with such variation of velocity as to show that its real period must be measured not by months, as bad been supposed, nor even by years, but by centuries. Probably it will not return till 600 or 700 years have passed. Had this not been proved, we miglit have been not a little perplexed by the return of apparently the sume comet in this present year. A comet was discovered in the south early in January, whose course, dealt with by Professor Kruger, one of the most zealous of our comet calculators, is found to be partially identical with that of the four remarkable comets w-e have been con- sidering. Astronomers have not been moved by this new visitant on the well-worn ti-ack, as we were by tlie arrival of the comet of 1882, or as we should have been if either the comet of 1882 had never been seen, or its path had not been shown to be so wide ranging. Whatever the comet of the present year may be it was not the comet of 1882 returned. No one even supposes that it was the comet of 1880, or 1843, or 1668. Nevertheless, rightly apprehended, the appearance of a comet travelling on appreciably the same track as those four other comets is of extreme interest, and indeed practically decisive as to the inter- pretation we must place on these repeated coincidences. Observe, we are absolutely certain that the five comets are associated together in some way ; but we are as abso- lutely certain that thej- are not one and the same comet which had travelled along the same track and returned after a certain number of circuits. We need not trouble ourselves with the q>ie.stion whether two or more of the comets may not have been in reality one and the same body at different returns. It sufKces that they all five were not one ; since we deduce precisely the same conclusion whether we regard the five as in reality but four or three or two. But it may be mentioned in passing as appearing altogether more probvble, when all the evidence is considered, that there were no fewer than five distinct comets, all travelling on what was practically the self-same track when in the neigh- bourhood of the sun. There can be but one interpretation of this remarkable fact — a fact really proved, be it noticed (as I and others have maintained since the retreat of the comet of 1882), inde- pendently of the evidence supplied b}' the great southern comet of the present year. These comets must all originally have been one comet, though now they are distinct bodies. For there is no reasonable way (indeed, no possible way) of imagining the separate formation of two or more comets at different times, which should thereafter travel in the same path. No theory of the origin of comets ever suggested, none even which can be imagined, could account for such a peculiarity. Whereas, on the other hand, we have direct evidence showing how a comet, originally single, may be transformed into two or more comets travelling on the same, or nearly the same, track. The comet called Biela's, which had circuited as a single comet up to the year 18-46 (during a period of unknown duration in the past— probably during millions of years), divided them into two, and has since broken up into so many parts that each cometic fragment is separately undis- cernible. The two comets into which Biela's divided, in 1846, were watched long enough to show that had their separate existence continued (visibly) they would have been found, in the fulness of time, travelling at distances very far apart, though on nearly the same orbit. The distance between them, which in 1846 had increased only to about a quarter of a million of miles, had in 1852 increased to five times that space. Probably a few thousands of years would have sufliced to set these comets so far apart (owing to some slight difference of velocity, initiated at the moment of their separation) that when one would have been at its neare.st to the sun the other would have been at its farthest from him. If we could now discern the separate fragments of the comet, we should doubtless recognise a process in progress by which, in the course of many centui-ies, the separate cometic bodies will be di.sseminated all round the common orbit. We know, further, that already such a process has been at work on portions removed from the comet many centuries ago, for as our earth passes through the track of this comet she encounters millions of meteoric bodies which are travelling in the comet's orbit, and once formed part of the substance of a comet doubtle.ss much more distinguished in appearance than Biela's. There can be little doubt that this is the true explanation of the origin of that family of comets, five of whase members returned to the neighbourhood of the sun (possibly their parent) in the years 1668, 1843, 1880, 1882, and 1887.* But it is not merely as thus explaining what had been a most perplexing problem that I have dealt with the evidence supplied by the practical identity of these five comets' orbits. When once we recognise that this, and this only, can be the explanation of the associated group of five comets, we per- ceive that very interesting and important light has been thrown on the subject of comets generally. To begin with : what an amazing comet that must have been from which these five, and we know not how many more, were formed by disaggregative proces.ses — probably by the divellent action of repulsive forces exerted by the sun I Those who remember the comets of 1843 and 1882 as they appeared when at their full splendour will be able to imagine how noble an appear- ance a comet would present which was formed of these com- bined together in one. But the comet of 1880 was described by all who saw it in the southern hemisphere as most remarkable in appearance, despite the faintness of its head. The great southern comet of the present year was a striking object in the skies, though it showed the same weakness about the head. That of 1668 was probably as remai-kable in appearance as even the comet of 1882. A comet formed by combining all these together would cert^nnly surpass in magnificence all the comets ever observed by astronomers. And then, \yhat enormous periods of time must have been required to distrilnite the fragments of a single comet so widely that one would be found returning to its perihelion more than two centuries after another I When I spoke of one member of the Biela group being in aphelion when another would be in perihelion, I was speaking of a difference of only three and one-third years in time ; and even that would require thousands of years. But the scattered cometic bodies which returned to the sun's neighbourhood in 1668 and 1887 speak probably of millions of years which have passed since first this comet was formed. It would be a matter of curious inquiry to determine what may have been the condition of our sun, what even his volume, at that remote epoch in history. * It may be interesting to compare the orbital elements of the five comets above dealt with. They may be presented as follows ; but it should be noticed that the determinations must be regarded as rough In the case of Comets I. and V., as the observations were insufficient for exact determination of the elements : — I. 11.

SIR HENRY ROSCOE ON ATOMS. |HE general press has done scant justice to Sir Henry Eoscoe's Presidential Address to the British Association, the Times leading the way in speaking of it as too- technical both in subject and treatment. Doubtless it is so for the majority of readers, who need everything pounded into pemmican or con- densed into a sort of Liebig's Extract, but not for those who desire to know as far as can be known everything about something rather than something about everything. Sir Henry wisely talked on the subject of which he knows most, and bis words were as admirable and clear as his substance was weighty and suggestive. After justifying the researches of the chemist by their economical results, he pointed out how at the back of all speculations concerning the nature of the motions of which matter is the vehicle, there lies the profoundly interesting question as to the nature and mutual relations of the atoms themselves, the building materials of the universe, and which have known no change amidst the ever-changing combina- tions into which they enter. Eighty years ago, Dal ton, working in no luxurious labora- tory.but "with the meagre apparatus of a few cups, penny ink-bottles and self-made thermometers and barouieters, dis- covered that a'oms combine in deBnite proportions of weight and volume with other atoms. He thereby changed chemistry from a qualitative to a quantitative science, giving an impetus to research which at last promises to bring us within sight of the fulfilment of Faraday's prophecy, that " in the end there will be found one element with two polarities." Many workers followed on the lines laid down by Dalton ; notably Prout, who formu- lated the theory that the atomic weights are multiples of the atomic weight of hydrogen, the lightest of the .so-called elements, and which he argued might be regarded as the primordial element, the materia prima, from which the others are formed by successive condensations. The researches of the past few years establish the fact that certain of the elements possess such strongly marked likenesses as to warrant their classification into groups, but the.se groups did not appear to be connected with one another, nor to have any relation to the f;xr larger number of elements not falling into groups. Recently, however, a marked advance towards proof of the common origin of all the elements has been made, in which an English chemist (Newlands) led the van, but in which a Eussian chemist (Mendelejelf) has outstripped him in showing that if the seventy "elements" which have thus far been discovered are arranged " in the order of their atomic weights from hydrogen as 1, to uranium, the heaviest, as 240, the series does not exhibit continuous advance, but breaks up into a number of sections, in each of which the several terms pre- sent analogies with the corresponding terms of other series. Thus, the whole series does not run a, b, c, d, e, f, g, h, ic, (fee, but a, b, c, d ; A, B, C, D ; «, fi, y, 8, and so on, in recurring similarities." In this we have a periodic law, as it is called, which embraces all the elements according to the increasing value of_ their atomic weights, and which has restored to their rightful place in the succession certain elements for which no place in any of the series of groups could be found. More than this, .and as evidencing to the fruitful play of the imagina- tion, ISlendelejeB', finding certain gaps between neighbouring elements, pointed out that they could only be filled by elements possessing chemical and physical properties which he accurately specified. And, sure enough, some of these vacancies have been filled by the discovery of elements with the properties which Mendelejefi' predicted they must possess. This is as interesting a romance as the discovery of Neptune, the existence of which, it will be remembered, M. le Verrier and Professor Adams independently deduced from the anomalous movements of Uranus, and which " floated into the ken " of Dr. Galle at Berlin when he pointed his telescope to that part of the heavens where the mathema- ticians told him he wovild find the planet. Commenting on this significant grouping of atoms, Pro- fessor Huxley, in his masteily siu'vey of the progress of science in Mr. Humphry Ward's " Eeign of Queen Victoria," says that it " is a conception with which biologists are very familiar, animal and ])lant groups constantly appearing as series of parallel modifications of similar yet different primary forms. In the living world, facts of this kind are now understood to mean evolution from a common proto- type. It is difiicult to imagine that in the not-Hving world they are devoid of significance. Is it not possible, nay pro- bable, that they may mean the evolution of our ' elements ' from a primary form of matter? Fifty years ago such a suggestion would have been scouted as a revival of the dreams of the alchemists. At present it may be said to be the burning question of physico-chemical science." And although no known energy heat that we ain apply Gin separate any one atom into two, so that, as Dalton said, " no man can split an atom," we do not any longer speak of it as indivisible ; all that can be said is that it has not yet been divided. That triumph awaits the chemistry of the future, and, when it is accomplished, the witness to the imity of the universe will be complete. coucealcL SHAKESPEARE AND BACON.* By Benvolio. ' Though in thy stores' account I one must be ; For nothing hold me, so it i^lease thee hold That nothing me, a something sweet to thee : Make but my name thy love, and love that still. And then thou lov'st me, for m)' name is WILL." Ska Iirfjica re's " i'onnets." N" the -'Nineteenth Century" for May 1886 an article appeared, in which a particularly pre- posterous development of the absurd Baconian theory of Shakespeare's plays was brought before the notice of Shakespearean students. We were assured that Mr. Ignatius Donnelly had discovered a cipher which had been craftily within the folio edition of Shakespeare's plays, published after his death, and that in two or three months Mr. Donnelly would publish most surprising readings from the cipher. It does not seem that Shakespearean scholars were very much impressed. The best of them all, the late Dr. Baynes, editor of the '• Encyclopaedia Britannica," brought out half a year later an appreciative essay on Shakespeare, in which the Baconian theory was not even mentioned. And now Mr. Donnelly feels moved to repeat his assertions and to renew his promises. In the first |)lace, Mr. Donnelly has persuaded himself that Bacon took special interest in planning cipher systems by which recoi-ds, such as could not safely be published, * It is proposed to enter presently in these columns into the study of Shakespeare's nature as unconsciously disclosed in his works, whence also something of his life may perhaps be gleaned. The present essay, from the American " Forum " for October, may be regarded as fitly introducing the series of papers thus planned, llr. Donnelly's foolish assault on the character and capacity oE Shakespeare having in reality (absurd though it was in itself) started tlie line of thought of which the proposed series of papers will be the outcome. November 1, 1887.] ♦ KNOWLEDGE ♦ 17 might be preserved ready for reading, when, later, the key of the cipher was indicated. As a matter of fact, when dealing with " Writing," in the third division of his section on the " Organ of Speech " in his " De Augmentis," Bacon does describe a cipher of his own, which he invented in his youth, at Paris.* But Mr. Donnelly would have done well to notice that Bacon very definitely expresses his opinion about the qualities which a good cipher should poosess. If Mr. Donnelly is right about the imagined cipher in the folio edition of Shakespeare, that cipher would be a very bad one, according to Bacon's ideas. " A good cipher," says Bacon, " mu.-t absolutely elude the labour of the de- cipherer," which the folio cipher has failed to do ; and " it must yet be commodious enough to be readUy written and read," whereas the cipher in the folio, according to Mr. Donnelly'.s own account of it, would have been fearfullj' difficult to write, and, as we can judge from the long delay of Mr. Donnelly's promised volume, and the small portion of the folio which he promises to decipher at first, the cipher is singularly difficult to read, even when its key has been discovered. Passing over the overwhelming antecedent improbability that Bacon ever wrote a line of the Shakespeare plays, and the extreme unlikelihood that he would have devised so cumbrous a cipher (when a few documents left to be read fifty j"eai's or so after his death would have served the full purpose attributed to him), let us consider the evidence in detail. Mr. Donnelly believes that the words of a hidden narra- tive were to be placed in such situations in the plays, as printed in the folio edition, that when the key was dis- covered the whole narrative could be put together, Bacon's authorship proved, and many un.suspected details of his life, and of the history of his period, disclosed. It is not easy to present with gravity the first pait of the evidence on which this idea, antecedently so absurd, has been baaed. We ai'e told that Bacon felt sure some student of Shakespeare would notice the frequent appearance of the words " Francis," " Bacon," " Nicholas," " William," " Shakes," " peere," " Shake," " speare," " spurs," " spheres," &c., in the his- torical plays ; he knew further that the ingenious student of the future would immediately associate this observed fact with what Bacon had said about ci]jhers in his " De Augmentis," and, " having once started upon the scent, would never abandon the chase until he had dug out the cipher." The mixed metaphor is Mr. Donnelly's own. But now see what curious proof of the existence of special peculiarities Mr. Donnelly has obtained. On page o3 of the '■ Histories" the word " Bacon" is the 371st from the top of the first column. Now there are seven italic words in that column. Multiply 53 by 7 and we get 371! On page .54, we find in the first column twelve words in itjdics. Midtiply 54 by 12 and we get 648. Counting words from the top of the first column of page 54, we come to the word " Chuffes," in which even the lively fancy of a Donnelly cannot recognise any specially Baconian significance. It is rather hard, because the word " Bacon " occurs in the poetic compound " bacon-fed," thirty-two words earlier, and the word " Bacons," eight words further on.f * The cipher is interesting as anticipating the Morse alphabet, in so far as it depends on the varied placing of things of two different kinds — Italic letters and Koman letters in the case Bacon describes. t I venture to offer Mr. Donnelly a hint, just here. May not these numbers, .32 and S, be highly sigaiticant i Eight is contained four times in thirty-two. Xow the word " Bacon'' appears only four times in all Shakespeare's plays; and in two of these cases it appears not simply as " Bacon," but in one place as " Bacons " and in the other as part of the compound " bacon-fed." Now, applying a certain rule we imagine we have discovered, we fail to get any Baconian word, but we find two of the " Bacons " out of all the But Mr. Donnelly is not to be foiled by such a difficulty as this. Nay, he does not even mention it. Not finding anything to suit him on page 54, from which he had obtained the number (j48, he turns back to page 53, without any reason assigned, and finds there the t548th word to be Nicholas — tlie Christian name of Francis Bacon's father. Even this marvellous result is only obtained by humouring the count. Mr. Donnelly admits that in this case words in brackets are to be omitted ; and he must have some system of counting hyphenated words as one or two to bring out the desii-ed result, or else such words as "'twere" for "it were " " a clocke " for " o'clock," and so forth, may be con- sidered single or double as required. Mr. Donnelly appears not to have been deterred by the failure of the method on page 54 from trying it on page after page, until at last, coming to page 67, he obtained something like a success — at least, to one so sanguine as himself. There are six italic words in the first column of page 67, 6 times 67 is 40l*, and the 402nd word on page 67 is " S. Albores," for " St. Albans," the place from which Bacon's title was fciken. It rather impairs the value of this coincidence that if we are to take " S. Albones " thus as one word, so also should we take " S. Nicholas " as one. Mr. Donnelly has already taken just so much of this word as his case wanted ; though, indeed, the iniquity which his theory attributes to Bacon, Shakespeare, Ben Jonson, and all others supposed to be in the plot, is so great, that he might well have taken the whole word — the name of the patron saint of those who commit rascality under cover of darkness — as specially belonging to the imagined cipher system. What he does in one case he should do in the other, only it would not suit his theory to have only " Albones." I cannot weary the reader with examples of other methods of counting, invented by Mr. Donnelly to serve as occasion mav require. It must be admitted that it is not his fixult that no constant rule will serve him. Sometimes he must be free to multiply by the number of words in brackets instead of by the number of words in italics ; sometimes to count from the top of the page itself, sometimes from the page before, sometiiues from the page after; sometimes to count hyphenated words as single, sometimes as double, and so on. But I cannot follow him in detail, because no sensible reader can be expected to examine many of these inanities. Suffice it that among the words found by these multitudinous devices are " volume," " maske," " his," " greatest," '• therefore," " shown," " image," " but," " own," and others, which assuredly no one but Mr. Donnelly will regard as amazingly significant. One case only will I cite as illu.strating Mr. Donnelly's singular readiness to be startled into conviction by casual coincidence. The reader should carefully note each detail separately, for there is absolutely nothing to connect them together. The number of page 75 multiplied by 12, the number of italics in the first column of another page, page 74, gives tiOO; and the number of page 76, multiplied by 11, the number of words in brackets in the first column of the same page 76, gives 836. Now counting from the top of the first column of page 74, omitting words in brackets, and counting the hyphenated words no longer as two words but as one, the 83Gtli word will be found to be the 304th word of four in Shakespeare on either side of the word we have lit upon — one of them four times as far from it as the other. " Can this be accidental?" Mr. Donnelly should have inquired. Are not the chances thousands to one against the occurrence of so many twos and fours in connection with the word "Bacon"? If any doubt can remain on this point, it ought to vanish when we notice that the numbers 8 and ?>2 are each multiples of four and powers of two, these powers being also four less one and four plus one respectively . One can go on with such drivel, however, indefinitely. 18 ♦ KNOWLEDGE ♦ [November 1, 1887. page 75, and is the amazingly significant word " found " ! Beginning from the top of page 75, and counting onward in the same way, the 836th word is " out." But counting from the same points, taking in the words in brackets, and counting each hvplienated word separately, we find the same two words, " found " and " out," each as the 900th instead of the 83()th word in its respective count ! On attaining this result, about as interesting as the dis- covery that the number of words in one of the books of the " Iliad " or " Odyssey " chances to be a perfect square, Mr. Donnelly exclaims : " Can any man believe that this is the result of accident 1 It could not occur l)v chance one time in a hundred millions. The man who can believe this is the result of chance would, to use one of Bacon's compari- sons, ' believe that one could scatter the letters of the alphabet on the ground, and they would accidentally arrange themselves into Homer's Iliad.' " It must be admitted, however, that the error into which Mr. Donnelly foils as to coincidences of the sort is a common one. " What strange hands were dealt us," someone will say at whist ; "I wonder what the chances were that those particular hands would be dealt : millions to one against, I should imagine ! " The answer is that the odds were more than six hundred and thirty-five thousand millions to one against those exact hands, but that the question of chance is not affected. Every set of hands at whist might he regarded as a mar- vellous coincidence if we viewed the matter in that way. The real question is. What is the probability that in a given set of hands odd coincidences may be found, if we look care- fully for them 1 and the answer is, that nearly always you can find such coincidences if you look for them with suf- ficient patience. And so it is with such counting of pages, italics, brackets, words, hyphens, &c., as Mr. Donnelly has fruitlessly undertaken. You are bound to find hundreds of siich coincidences as he notes for marvels. But we must notice also the str.ange reasoning by which Mr. Donnelly has persuaded himself that the text of the folio has been altered — " twisted," as he sa3's, " to conform to the requirements of a mathematical cipher "■ — -though Bacon was weak indeed in mathematics. Mr. Donnelly notes the appearance of italicised words, hyphenated words, and words in parentheses, which he insists on calling brackets, and represents as brackets when (pioting. He does not seem aware of the fact that when the folio was printed it was the custom to italicise all pro])ei' names as they are italicised in the folio, to hyphenate all connected words, such as "lean-on," "get-over," " find-out," &c., and to use parentheses to inclose words presenting an interjected expression or thought, which in modern printing would ordy be inclosed between commas. (I prefer this old usage myself.) To show how ready Mr. Donnelly is to imagine peculiari- ties where in reality all is in order, I note that he regards the lines " You are too {jreat to be (by me) gainsaid," and •' I cannot think (my Lord) your son is dead," as printed in an unusual and unnatural fashion ; and he asserts that in the first part of " Henry IV," such phra.ses are not so printed. Yet had he but turned for comparison to the most striking of all these passages in the first part of " Henry IV." which relate to the Percy plot, he would have found the lines " This bald, unioynted Chat of his (my Lord) Made me to answer indirectly (as I said)," precisely matching the cases which he deems so strange. It would lie impossible to convince Mr. Donnelly that lines which he quotes as strange, coutoi'ted, confused, &c., are perfectly natural and especially Shakespearean ; for he mani- festly has not the slightest germ of the faculty which enables the critic to recognise at once the touch of Shakes|ieare's hand. He finds such expressions as " the dole of blows," walking '• o'er perils on an edge" (compare "on the unstead- fast footing of a spear "), and so forth, altogether unnatural. He cannot even understand so simple a passage as — " The lives of all your lovicf;' complices Leane-on your health, the which, if you give o'er To stormy passion, must perforce decaj' ; " asking gravely how lives can decay, when Shakespeare clearly speaks of Northumberland's health decaying. But the greatest absurdity of all, in this connection, is Mr. Donnelly's elaborate mystification in regard to the lines " Or what hath this bold enterprise bring forth, More than this being which was like to be / " Of course, " bring " is a misprint for " brought " : the folio is far from being so carefully printeil that that need astonish us. But Mr. Donnelly says the line '• more than this being which was like to be," reads like an extract from Mark Twain's recent essay on " English as She is Taught." Yet, even as Mr. Donnelly misquotes the line, it should perplex no one. " What," asks Morton. " hath this bold enterprise brought forth, more than this comlition of affairs which was likely in any case to have come to pass 1 " It should be noticed, by the way, that iu the folio the line runs — " More then that Being, which was like to be ? " " Then " is equivalent to " than," and " that " slightly alters the sen.-e ; but the point to be noticed chiefiy is that the cajiital " B" marks the word " Being" as a noun (condition, state of affairs), and not the participle for which Mr, Donnelly has manifestly taken it. The comma, also, after Being, makes the sense obvious. The meaning of the passage should be clear, however, without this evidence from the folio itself. With a lively imagination for the suggestion of im- possibly ingenious cipher systems, and complete freedom from such restraints as Shakespearean scholarship would impose, Mr. Donnelly may read almost anything in the folio edition of Shakespeare. He can make his own history of Bacon's secret Shakespearean life, and find every item of it in the plays as printed in that edition. I have little doubt that in this w.ay he has found already, to his own satisfac- tion, what wo\dd be most surprising if really regarded as the work of Bacon. The first sentence lie ]iublicly claimed to have read would of itself astound any one who had made any acquaintance with Elizabethan literature. It begins, '* I was in the greatest fear that they would say that the image," &c. He might almost as reasonably have made Bacon say, " It was too awfully awful to think that they would say that," etc. Not a sentence published between the years 1.550 and 1050, or even until later than 1750, re- sembles in structure the sentence attributed by Mr. Donnelly to Bacon, a master of the tersest stj'le of which the English language is capable. Mr. Donnelly's marvellous first-fruit was not only a sentence of purely nineteenth-century English, but a very clumsy example even of that. Finally, Mr. Donnelly pretends to wonder that English- men should be wroth with him for striving (as he puts it) to pass tiie fame duo to the author of the plays from one celebrated Englishman to another. The pretence is twofold. No Englishman that I have ever heard of, and no American of English descent (to whom Shakespeare's fame must be as dear as to the native-born Englishman, since birthplace is the merest accident), has ever viewed the Baconian theory of Shakespeare's plays with an}' feeling resembling wrath. A foolish fancy like that theory may provoke a smile, but certainly no anger ; and our amusement can only be in- tensified by such an amazingly absurd extension of the November 1, 1887.] ♦ KNO^A^LEDGE ♦ 19 theory as Mr. Donnelly has wandered into. But the theory, could it lie established, would not hand the fame of " gentle Will Shakespeare" to Bicon, the keen logician and potent reasoner ; it would bring discredit to tiie n imes of both, as also to others esteemed for varied attainments and qualities, whom the Baconian theory associates with Shakespeare and Bacon in a cowardly and shameful plot. By Eichard A. Proctor. Ix this number are begun several of the subjects promised in the announcements made respecting the eleventh volume of Knowledge. How much more might be done if the public would give one tithe of the support to a magazine relating to science which they will give to a magazine incorpo- rating sensation stories by tenth-rate novelists, few, save the proprietoi's and publishers of scientific magazines, can guess. Every month's issue of a magazine like this involves a sacri- iiee of time, labour, and money, entirely inconsistent with the sound old saying that " the labourer is worthv of his hire." * * * By an odd coincidence, just after reading through, in Knowledge for September, an article in which true loyalty and false loyalty were contrasted, I opened the October issue of " The Forum " at the stupendously silly — unless it is to be considered the bitterly sarcastic — article by General Lord Wolseley on " Queen Victoria's Eeign." General Wolseley found in the Jubilee clatter evidence of love for a family representing " all that we most delight to dwell on in our history," " the heirs of our lion-heai-ted Eichard " (recognised Ijy history as one of the coarsest, and at heart most cowardly of ruffians), " of our Henries of York and Lancaster" (the Henries of York are unknown to history, and onh' one Henry of Lancaster was even respect- able in character and conduct, the fourth Henry being a treacherous murderer, and the sixth a nonentity), and "of our own great Tudor Elizabeth." Queeu Victoria's kinship to Elizabeth is remote — to say the least — considei'ing that we have to go back to Henry VII. befoi-e we can advance down the line of descent to the one Stuart King of England, through whom the Hanoverian line claims kinship with the earlier mouarchs of this country. But when we consider that less than a thousandth part of the Queen's blood came from that Stuart monarch, it is rather absurd to grow en- thusiastic about the attributes of the present royal family. Ask Mr. Francis Galton how much of the old fighting and ruling qualities of the Xorman kings could have been handed down by direct hereditary descent even to the later Plan- tagenets, and his answer will hardly favour the idea that, for example, George III., whom WolseJey openly ridicules as a blundering old ass, or George IV., whom solier history recognises as a brainless and heartless humbug, could have inherited any exceptionally kingly attributes from those ad- mirable ancestral plunderers. Loyalty like Wolseley's, which depends solely on the asserted amiability and good sense of the actual monarch, and openly despises her nearer ancestry, is not loyalty at all, even of the poor kind considered — and assuredly cannot be tinselled into better semblance by refer- ences t ) far-back ruffians palmed off in children's histories as gallant knights and able rulers. * * * It is not here and thus, however, that General Wolseley chiefly blundeis in his easily explained enthusiasm. He deliberately quotes, as the most characteristic samples of true loyalty, conduct which in the selfsame breath he calls superstitious or silly or ignorant (or all three). He was " much struck " by " a newspaper descrijition of the unveil- ing of the Queen's statue in India," telling how the ignor.ant natives, regarding it as a kind of idol, " rushed forward and kissed the feet " of it ! " The simpler the nature of the peeple," he justly says (he mzist mean his whole article ironically), " the more unquestioning is their religious faith and that loyalty which is akin to it." Then he tells how a little girl, after the Hyde Fni-k fete, went home and told her mother she had seen a balloon go up which had taken "the Queen to heaven." " The idea may " (sic) have been '' silly in itself, but it signified a train of reasoning in which loyalty was evidently a prominent element." Could anything more sarcastic have possiblj' been said by the keenest advocate of true versus false lojalty ? * * * Nest, the gallant opponent of the superstitious but most loyal followers of the Mahdi tells us how " a ])oorly-clad nursemaid, pushing a perambulator before her through the crowds in the ' East End,' " expounded //cr ideas about the Queen — and he grows enthusiastic over her utterances : " This simple nursemaid," he says, '• like millions of other people, was imbued with the species of hero-worship which in monarchies is known as loyalty." * * * Then he somewhat liberates the feline from its encom- passment by dwelling on the fact that " personal devotion to the sovereign is more apt to be" (or to seam) lively, " when all favours, rewards, and punishments emanate directly from the throne : the less this is the case, the feebler we should expect to find those feelings of which loyalty is compounded." Pos.sibly General Viscount Wol.seley has had occasion to appreciate both that kind of gratitude which has been described as " a lively sense of favours to come," and that anxiety as to punishment which naturally, as he says, suggests the sense of personal — aye, intensely personal — loyalty. If so, he may well ask, consciously and anxiously, whether the spirit which teaches men to despise adulation of the powerful and to advocate true self-respecting loyalty, "confers a boon upon mankind " (as represented by number one) in " seeking to eradicate loyalty " (of the false kind) " from the human heart." But if this is the way in which such friends of loyalty, falsely so called, defend it, such loyalty, could it but speak for itself, miglit exclaim " Save me from my friends," — with almost as much reason as Gordon at Khartoum. MYTH, RITUAL, AND RELIGION.* HE science of comparative mythology is for- tunate in having had the methods of its expositors subjected to severe tests at what is still an early stage of its history. We owe no small debt to the scholars who rescued materials which imbed men's thoughts while at low levels of culture from the hands of dictionary-makers .and allegorists, and who made plain its deep and long hidden significance. But this must not blind us to the defects of their method, which, as our readers scarcely need to be reminded, explains the repulsive and ludicrous features in the myths of higher races as due to what Professor Max Miiller calls a " disease * " Myth, Ritual, and Religion.' a; Co. By Andrew Lang. Longmans 20 ♦ KNOWLEDGE ♦ [November 1, 1887. of language," to the forgetting of the purer primitive meaning untlerlpng the names of the gods and heroes of mytholog}', and which it is contended, by an appeal to their supposed etymologies, were, in the first instance, names of the sun, the dawn, the tliunder, and so forth. The arguments in support of this, presented in attractive guise and with much show of reason, in Professor Max Miiller's well-known essay, reprinted in the first volume of his " Chips," and elaborated in Sir George Cox's " Mythology of the Aryan Nations," have held the fiekl for some years, being only now and then attacked by skirmisliers, or by the light artillery of clever parody. But of late a growing feeling of the insufficiency of a method which rests chiefly on evidence from words as to whose meaning experts difler, and which, moreover, interprets only the myths and rituals of ancient and modern civilisations, while ignoring or under- valuing those of savage races, has arisen, the result of which is to condemn that method as untenable in the main, and as applicable only to a very small portion of the great body of myth. The impetus to this discrediting of etymology as the sole key to interpretation came from a comparison of the myths of the higher with those of the lower races, which brought out the fundamental likenesses between them in the coarse and wild elements common to each. Anthropologists ex plain the presence of these elements in Greek, Vedic, and other mythologies, as survivals from the lower culture out of which Greeks and Brahmans have emerged. They are the old Adam which has never been cast out. Like the ancestral l^istory of the type which the embryo repeats in its advance from the egg to the full-grown state, myths pre- serve traces of the intellectual and spiritual tj'pes in which their earliest forms were cast, and thus add their witness to the unity and continuity of history. Thus viewed, myths, rituals, and religions, wherever found and in whatever refined or unrefined connection, fall into their related place in the general march of man's de- velopment. It is of this sound and verified method of anthro|)ology — which has no limitation of race or zone — that Mr. Lang is the most prominent and cultured ex- ponent. He can claim for it, as his letter to Eusebius in the delightful " Letter's to Dead Authors " shows, a vener- able antiquity, since the learned Bishop of Cresarea, in treating of the " pagan " mythologies, argued that " they descend from a period when men in their lawless barbarism knew no better than to tell such tales. Ancient folk in the exceeding savagery of their lives made no account of God, but betook them to all manner of abominations. Growing a little more civilised, men sought after something divine, which they found in the heavenly bodies. Later they fell to worshipping living persons, especially medicine men and conjurors, and continued to worship them even after their de- cease, the Greek temjjles being really tombs of the dead. (Which, by the way, applies to every Roman Catholic church, since, according to Papal traditions, unconsciously conserv- ing the barbaric worship of ancestors, there can be no altar where there are no relics.) Finally, the civilised ancients, with a conservative reluctance to abandon their old myths, invented for them moral or physical explanations like those of Plutarch and others earlier and later." Mr. Lang's diligence has also unearthed an essay by Fontenelle, a nephew of Corneille, which was published in 1758, and in which he explains the absurdities of the old mythologies as the legacy of the savage and ignorant an- cestors from which every civilised race is descended. He " concludes that all nations made the astounding part of their myths while they were savages, and retained them from custom and religious conservatism." This could not be better or more briefly put. The space given to a quarterly review article would only suffice to furnish an outline of the profusion of illustration from ancient and modern sources with which Mr. Lang supports his general thesis. The present volumes — as easy to read as a novel, and far more entertaining than nine- tenths of the novels published nowadays — are a careful and elaborate restatement of all that Mr. Lang has hitherto published in fugitive form or in the more collected essays comprised in his earlier book on " Custom and Myth," which was the subject of a lengthy notice in this journal three years ago. Brushing aside the notion that even in the lowest and crudest myths we touch the beginnings of thought, Mr. Lang gives a rapid but sufficient survey of the interpretation of ancient and modern mythologists, wisely transferring his answer — complete and crushing as it is — to the objections raised against the anthropological methods, chiefly by Pro- fessor Max Miiller, to an appendix. The body of the book is thus relieved of contentious matter, and filled with ex- amples drawn from the lower and the higher culture, bringing out with clearness the remarkable coincidences between the myths of Greeks and Bushmen, of Finns and Kaffirs, of Aztecs and Zulus. Some prominence is given at the outset to the widespi-ead — we may say universal — attri- bution of life and personality to everything by savages, and to their belief in descent from sun, animal, or plant, as the key to their theologies, rites, and customs. Very much remains unexplained, but the agreement of the evidence drawn from races between whom no intercourse has taken place since their first dispersion leaves little doubt that such practices as the prohibition against marriage between members of the .same tribe-name or totem, and against eating the animal which gives its name to the totem, arise from belief in the near kinship of man and brute. Mr. Lang's skill in disentangling an intricate subject from the webs of theory-spinners is markedly shown in his two chapters on the gods of the Indian Aryans and on the mythology of Egypt. His sanity of view is apparent in the conclusions at which he arrives concerning the latter, and which agree with the general conclusions reached through- out the volumes. " In Egypt, as elsewhere, a mythical and a religious, a rational and an irrational, stream of thought flowed together, and even to some extent mingled their waters. The rational tendency, declared in prayers and hymns, amjilifies the early belief in a protecting and friendly power making for righteousness. The irrational tendency, declared in myth and ritual, retains and elaborates the early confusions of thought between man and beast and God, and between things animate and inanimate. On the one hand, we have almost a recognition of supreme divinity ; on the other, savage rites and beliefs shared by Australians and Bushmen. Egyptian religion and myth are thus no isolated things ; they are Ijut the common stuff of human thought decorated or distorted under a hundred influences in the course of unknown centuries." Mr. Lang has an easy task in explaining why certain groups of myth, even those of whole races, as Finns and Scandinavians, should be excluded, at least, for the present, unless his volumes are to grow to unwieldy size. But he gives no reasons for the omissions, here and there, which betray a reluctance to include the myths and legends of .Judaism and Christianity as due to the like ciiuses which explain the myths and legends of other religions. Silence upon this subject does harm in fostering prejudices which ai-e strengthened when the mythologies and cosmogonies of a Semitic tribe are treated as an integral part of sacred writings into which there enter elements as coarse and crude as those which are found in Yedic hymns and savage legends.

We can only conclude this inadequate notice by saying to the solar mythologists that if, after honestly weighing the arguments advanced in this important work, they be- lieve not Mr. Lang and his cloud of witnesses, " neither will they be persuaded though one rose from the dead." In Cheviots Glens. By Jane T. Stoddart. (Oli- phant.) — This is a very pleasantly written story of modern life on the Scottish Border. The scenes and characters are not ostensibly sketched from life ; but, presuming that they are, none of the originals would, we think, have any good reason to complain that Miss Stoddart had not done them justice. It is a little odd to find the shepherd's son marrying the squire's daughter, even though he was a " meenister " ; but we suppose '• they do these things better " in Scotland, or oftener, at any rate, than we do here. We have spent a very pleasant hour " In Cheviots Glens," and hope to meet Miss Stoddart in the neighbour- hood again. My 3Iicroscope ; and Some Objects from my Cabinet. By a QuEKETT Club-man. (Eoper &. Drowley, Ludgate Hill. Is. 6d.)— The Quekett Club, to which this'little work is dedicated, is not Ukely to increase its credit largely by the connection. We are totally unable to see the raison d'etre of the book. Gosse's " Evenings at the Micro-scope " has been cheaply reprinted. Houghton's " Microscope and the Wonders it Reveals " is selling at less than a shilling, and there are a dozen other little works which will each tell the beginner twenty times as much as he can learn from the pages before us. It is an elegantly got-up little book, thick paper, large type. The binding is good. The printing is well done. But that is all we can say of prai.se. The illus- trations are few and poor. One roughly depicting a hydra is suggestively labelled on the back " a monster." There is a group of diatoms fairly well drawn in the chapter on "A Skeleton." But the text, instead of giving even their names, indulges in a few generalities on Auhicodiscus orien- talis, which is not figured. The other chapters treat on "An Eye," "A Wing," "A Slice of Rock," &c., and make a few remarks on a spider, a butterfly, and so forth. The work contains 78 pages. Eighteen are absolutely blank ; eleven more, including tlie dedication and table of contents, share seventy-five words among them. In conclusion we can only regret that any one professing to love the micro- scope can say so little for it at the price. t A Junior Course of Practical Zoology. By A. Milner Marshall, M.D., D.Sc, M.A., F.E.S., assisted by C. Herbert Hurst. (London : Smith, Elder, & Co. 1887.) As an introductoiy text-book for the student of zoology, the work of Dr. Marshall and INlr. Hurst leaves httle or nothing to be desii-ed. Written with scrupulous care by men peraonally thoroughly familiar with the objects and processes they describe, and illustrated by woodcuts which, if few, are excellent, the student who will sedulously work through the graduated series of dissections so carefully and minutely treated of in it, will have attained a very con- siderable knowledge indeed of animal morphology. Our authors begin with the most rudimenfairy forms of life, the amoeba, paramecium, vorticella, (fee. (the so-called " infusoria ") ; and then ascend throvigh the hydra, the liver- fluke of the sheep, the leech, earthworms, and the like ; the crayfish, cockroach, lancelet, and dogfish, to the rabbit, fowl, and pigeon. An immense araouut of honest work is embodied in the volume before us, which will doubtless speedily attain high rank as a handbook in schools of anatomy and physiology. Lessons in Elementary Mechanics. By W. H. Grieve, P.S.A., late R.N. (London : Longmans, Green, & Co. 1887.) — In simple language, and with an abundant supply of illustrative woodcuts, Mr. Grieve treats of the six •' mechanical powers " of the old books on Natural Philo- sophy : the lever, the wheel and axle, the pulle}', the in- clined plane, the wedge, and the screw ; as also of liquid pressure, the hydrostatic press, liquids under the action of gravity, and the parallelograms of forces and of velocities. The examples selected are derived from objects in familiar use, and the pupil must be abnormally stupid or idle who foils to understand Mr. Grieve's very plain exposition of them. He has done his work well. Handbook of Practical Botany. By E. Strasbueger. Edited from the German by W. Hillhouse, M.A., F.L.S. (London: Swan Sonnenscheiu, Lowrey, & Co. 1887.) — We are glad to welcome Professor Strasburger's admirable manual of structural and physiological botany in its English dress, supplying, as it does, a want in our microscopical literature. Nor has our examination of the work seemed to furnish much, if any, justification for the apologetic tone in which Mr. HUlhouse speaks of his translation, since this appears, as far as we can judge, to render the sense, and even in some sort the diction, of the original very well indeed. Famed as Herr Strasburger is as a microscopical manipulator and observer, the exhaustive mass of detailed description of the dissection and preparation of plants for examination which this volume contains cannot fail to be of the greatest interest and use to the vegetable histologist and physiologist. Nothing is omitted which can facilitate the processes described, and profuse illustration supjjlements directions themselves of the most explicit character. There are careful tables of the plants used for study, the re-agents employed in their examination, preparations for mounting them, ifcc. In short, this is a book which every microscojjist ought to have, and every botanist must have. An Introduction to Machine Drawing and Design. By David Allan Low. (London : Longmans, Green & Co. 1887.) — This very practical little book is the work of a man thoroughly familiar with the subject of his descriptions, and who further possesses the faculty of impax-ting his own knowledge easily and pleasantly. It should be studied not only by the young engineer but by the fitter, turner, and, in "fact, everybody who has to make drawings of machinery or work from them. The Problem of Ecil. By DakielGreesleaf Thompson. (London : Longmans, Green, t Column. By "Five op Clubs." CLEVEELY B.\D I'LAT. HAVE given some attention for a long time past to the way in which good play at whist prevails over had play : so that although for an evening, or even for several days, inferior play may secure the greater number of points, in the long run better play tells, and a certain percentage of advance infallibly shows itself ere many hundreds of points on either side have been scored. Nearly always, I have observed, the moie scientific play (by which I do not refer to as knowing all the settled details of plaj- — the 'echo," the "penultimate," and so forth, but follow- such details " signal," the ing true strategic principles) succeeds most notably against those points on which the unscientific player is most apt to pride himself. Among these are : — (1) Playing for ruffs; (2) drawing two trumps for one when the enemy have declared great strength in trumps : (3) always declining to force the enemy; (1) putting off play by which a sure trick will go to the enemy — though nothing can prevent the trick so going, and it may be of es.-ential impor'ance to throw the lead into his hand at the moment ; but there are many other clever dodges which are sure ways to failure in the long run, though they may turn out well perhaps five or six times in a score of trials. But nothing shows the whist player better the value of sound play than to play for a while with a partner who does not under- stand the true principles of whist strategy, and puts trust in unsound dodges. Especially, while as yet he is unaware of his partner's foibles, does he suffer ; for with a partner of known ineptitude he. of course, does not attempt the higher strategy, knowing that his plans will inevitably be knocked on the head. Here is an example, which I will not put into tabular form, but describe it as it presented itself — unpleasantly — to my attention. I was the original leader, and, on examining my hand, found that it contained the following pleasing set of cards (the ace of spades having been turned on my right) : — Sjiades— queen, ten. nine, four, three ; diamonds — king, queen, knave, ten, eight ; hearts — ace ; and (•/«/'.«— king, nine. This was a charming hand to play, with a good partner, holding a fair supporting hand. The object to be aimed at, of course, is to bring in the long diamonds : and with five trumps, heart ace, and a guarded king in clubs, this seems very likely to be brought off. [The score was " One all."] Had I been free to look at my partner's hand in this case, I should have made sure of bringing it off with ease, unless he proved to tie a very weak player. Let us see what happened : — t)i course I led a spade, the original fourth best trump ; a small trump fell on my left; my partner played the knave; and the trump card, the ace, took the trick. My right-hand opponent, Z, led heart five ; my ace took the trick ; and four and three fell from T and B, showing that two must be with Z ; and, of course, three others, since he had led his fourth best. I now naturally led the spade queen, the three high trumps left in my hand being now in sequence. King took it on my right, my partner played a small trump, and Z renounced. This renounce looked, of course, un- favourable for my plans ; in fact, I could tell that Y either held two more or three: if he only held two, however, I was s ill sure of success in bringing in my diamonds, provided my partner played rightly. Y returned his partner heart six (the lowest left, except Z's two), my partner took the trick with the king, Z played the two, and I discarded club nine. At this stage tlie game was won. Jly partner held another small trump. We had already made two trices to the enemy's two. If my partner led his trump I should have made two inore tricks, extracting both Y''s ; have led diamond king, which Y would have taken with tbe singleton ace he held ; and on his leading a heart (his only reasonable lead, but it was indiff'erent what he held, as my partner held club ace) I should have ruffed and made mv four remaining diamonds, the last trick going to my partner's club ace. We should thus have made four by tricks. But my partner deliberately committed the atrocity of forcinc me (original trump leader though I was 1) by leading a heart, on which Z put a little one, so that I had not even the satisfaction of ruffing the best heart, yet was unable to resist the force, as I could place two more hearts in Y"s hand, so that the force could be repeated by him, and then by Z. (The inexperienced whist-player may ask how I knew Y had two hearts left : simply because my partner not leading the best, Z's play showed he knew Y could take the trick, which at once made his return of the lowest at the fotirth trick indicate three hearts then in hand, for every good player returns the lowest of three, the highest of two.) I therefore ruffed, and now, play as I might, we could make only two by tricks. I led my diamond king ; Y' took with the ace, and, forcing me in hearts, remained with two trumps to my one. It I had taken out both his trumps, and then led diamond king, he would have brought in his part.ner's hearts, and we should have fared worse. If I had taken out but one of his trumps and then played the diamond king, he could have forced out my last trump with a heart, and on ruflirg my diamond queen would have led his remaining heart. My partner's reason for his atrocious play was that he saw a chance of giving me a ruff, and making one of his own trumps in a ruff. For the chance of one trick (my rui", of course, was not a trick gained) he — the weak hand — ruined (instead of helping) the play of his strong-handed partner. It is because of such iniquities as these that Deschapelles said good players of their own hand are detestable partners. From some statistics I have been collecting now for two or three yeas 1 have been led to the conclusion that, while simply know- nothing partners lose about one trick in ten, clever playtis of their own hand lose about one trick in s^ven. LoNDOX Fogs. — Mr. Ernest Hart, of the Smoke Abatement Institute, fears that London will always suffer from fogs, because it is placed in a river valUy, on a clay soil, and is bordered on the Essex side by low-lying lands very imperfectly drained, and on the north side by the Harrow Weald. The fogs generated— the results of damp exhalations — are greatly aggravated b3- the parks, most of which require draining. But if the smoke is got rid of, the fogs will be much less dense. d^ur CI)f£!si Column. By " Mephisto.'' MATCH, BLACKBUEN'E v. GCNSBERG.

In Chinese, frequentatives or the repetition and continua- tion of an action are expressed by repeating the primitive syllable, as mo-?«o = to go on rubbing; ho-ho^bo keep on drinking; t'ia a- t'iau — to jump about. The repetition, however, sometimes serves to intensify the meaning of the primitive. It gives the notion of "a good many," "all," " every," to a single, as jin, man, jin-jin, everybody, * " Journal of the Anthrop.

Similarly in colloquial speech, we say, " He went on write, write, write ; " "I like it very, very much ; " " Oh, go on, talk, talk, talk," and so on. In the early stages of language there seems to have gene- rally prevailed a love of reduplication for the mere pleasure of repstitiou, as well as for the sake of greater clearness and pictorial eSect. In South America there is a river Bio-bio, a rodent tuco-tuco, and so on ; and the Maori dictionary is full of words of such formation as mati-mati, toe; emi-emi, tree ; dki-dki, to urge ; and dti-dli, to drive away. In Hebrew the superlative is formed by repetition of the ad- jective. In Breton from 7ndd comes mdd-mdd, best ; from fidl, bad, fall-fall, worst. The French have bon-bons, goodies. Reduplication seems, therefore, to intensify an action or quality ; and duration of time, as well as large- ness and smallness of dimension (intensification), is also ex- pressed by the lengthening out of vowels. With regard to the long vowel of the present ten.ses of Latin and Greek verbs, in place of the short vowels of the stems, and the strengthening of the final consonant, it has been suggested that its origin is really imitative, denoting the duration of the act, as when we say, " He came creeeping along,"or" He draairls out his words." Thus, phalno, scr'ibo, dlco. While, on the other hand, the short penult of etupon, elabon, elathon, &c., agrees with the momentaiy nature of the act.f In the many words and roots which I have mentioned, and in thousands of others which I might record if space permitted, the imitative or pictorial origin is clear ; and as I have shown + that the trace of the origin of words is easily and most frequently obliterated by the growth and wear aud tear of language, the inference is patent that imitation must have played a most important part, if not the most important part in the first development of speech. AMERICANISMS. Gobbler, for a turkey cock, is probably no more an Americanism than Bow-irow for a dog. Readers of "The Pioneers" will remember how the owner of the unlucky turkey to be shot at by Leatherstocking and the big Vermonter calls to his bird, " Poss up a gobbler." The expression belongs i-ather to nigger patois than to American English. Go. A State is said to go Democi'atic, or to go Repub- lican, when it votes for one or the other cause after being for a time doubtful, or on the other side. Go BV, To. To stay ; not to go by, as we understand the words in England. This peculiar usage belongs to the Southern States. The exj^lanation is not .so diflicult as might b3 expected. Where in journeying a traveller has a choice of ways, as in the South is generally the case, a friend will say to him, " Go by my plantation and stay with me," meaning simply choose that way. Later such a re- quest would be shortened into "Go by aud stay with me." Southerners do well to get a convenient expression for such cases, seeing that they are of all men in the world the most hospitable and generous. Go FOR, To. To go for any one, in the sense of attack- ing him, appears to be an expression of Southern origin, though now heard commonly enough all over the States. t T. H.

For if a Southerner's generosity knows no limit, neither does his combativeness, when he considers it j ustifiably excited. Go IT ALONE, To. In euchre a player may decide to play the hand alone, his partner turning down his cards (sometimes after giving the best card to the lone player, who then discards his worst). Success in such a case counts double, as also does failure. A player who thus decides to play alone, is said to " go it alone," and a similar expression is applied to one who decides to carry out any business operation on his own sole responsibility, and without help from others. Go IT Blind, To. At poker a player who bets on his hand before seeing it is said to "go it blind," and the usage is extended to any one who in any undertaking trusts I lindly to chance. Golly ! Used euphemistically (says Bartlett I) for "God." Dogberry could hardly have beaten this; God forbid but God should go before such a villainous niggerism as Golly.

E have received the following exhilarating letter from a correspondent who evi- dently does not appreciate " Our Whist Column ": — Exactitude being tlie chief corner-stone ot science, ought the word " scientific " to be applied to a game, of which a liaphazard groping in the dark is a chief cliaracteristic ? This is a question that recurs to me each month after a perusal of the Whist articles in Knowledge. Meanwhile I wonder how long there will be persons who entertain the belief that there is some liigh level of this happy-go-lucky game to which they attain, whilft they look down with contempt on what they style " Home AVhist." Whist, indeed, is a game of such complexity, the whole thing being worked, too, so much in the dark, that the " superior " player never discovers that he is living under a dehL-iion ; and, if he cannot show by final results that hi« play is more successful than the commonplace play of Mr. Humblemind [but Mr. Bumblepuppy never has a humble mind] " he falls back on his iad luck for an explanation." But is it possible that the human mind can go on deceiving itself in this way ? Certainly it may ; for is not the great whist player wlio lives in such delusion in the same boat with many other classes 1 For instance, there are those men who set them- selves up as judges of horseflesh ; they never in the slightest degree realising the complexity of the subject on which they pronounce their confident judgments, though it is perfectly clear to a man of discernment that the intrinsic value of an individual horse as a useful animal can only be discovered by long-continued trial. Politicians and philanthropists, again, deal with questions of great complexity without even for the most part ever discovering that they are so. No failure in the past abates their confidence as they press forward with one idea in their heads. Then there is the weather prophet. He, deluded creature, will call his forecasts " scientific." His case clearly justifies the belief that there can be men who hold that they play a superior " scientific " game, when in truth their play is in effect in no wise superior to that of any person with a passable memory, who can keep his mind on the carcl- table, and who properly appreciates the old proverb about '• a bird in the hand." Self-delusion being the explanation, we need not be astonished at what would otherwise be very surprising, namely, new orthodoxies springing up in whist, over-confident people now putting forward fresh discoveries, which they suppose to have been overlooked by hundreds of thousands of players ot past generations, who gave up almost their whole minds and time to the game. Neither need one wonder at seeing each high priest protesting that the other high priests have really no scientitic knowledge of the game on which they presume to instruct the laity. Fbancis Kam. Mr. Ram need not have been at the pains to go so far afield for illustrations of persons who knowing nothing of a subject delude themselves into the belief that they know a good deal. P^very paradoxist shares this delusion, and internal evidence might have shown Mr. Ram how natural it is. I may state one or two facts which should help to put Mr. Ram right, only I fear he will not accept them. First, scientific play does not depend quite so much on imaginary advantage as Mr. Ram imagines. The matter has been put to the test in the most crucial manner — scientific play being matched against unscientific over the selfsame hands dealt in the usual way to a set of players in one room, and repeated card for card for player.s in another room, and the superiority of science thus tested has come out in a way which surprised even experts. The details of the experiment are given in " How to Play Whist," pp. 199 to 201. Sufiice it here to .say that, in all, sixty-six hands were iilayed, absolute equality being secured in regard to cards ; and the scientific players came out eleven points, one. rubber, and twenty-orie tricks ahead of the un- scientific I Of course, the estimate by tricks is the truest ; and it is remarkable that, although, as luck would have it. the cards were very unequally divided in the two rooms, insomuch that in one room the good players were eighteen points ahead, while in the other they were seven points behind, they came out ahead, as reijards tricks, in both rooms, being nineteen ahead in one room, and two ahead in the other ! In passing, I may note, that I, of all men, least deserve to be charged with despising Home Whist, having written a little book under that name for the special inculcation of correct play. For two years past I have enjoyed sounder and better whist in my home circle than I have ever had or have ever seen played (in so many as half a dozen con- secutive sets) at an}' club. I have seen sound play matched against the clever plans of first-rate players of their own hands (or " bird-in-thebu-h " players) for game after game, till the tricks (honours being left uncounted) have amounted to thousands, and with as steady a gain by scientific p'ay at rates ranging from 8 to 12 per cent., as though the cards had been packed to secure it. I have seen scientific com- bined p'ay matched against the uncultured whist of a keen card player having single dummy for partner, and even here, where the odds are supposed to be nearly 10 per cent, in favour of dummy, scientific play has prevailed decisively (about 9 per cent.). At double dummy, of course, science is everything, and it very seldom happens that even at a single sitting of any length science is beaten by lucky cards. But in fact scientific players can recognise every trick secured by sound play or lost b}' irregular play. When an opponent, by playing out his aces and kings, gives up com- mand, and lets long suits come in and make trick after trick, the scientific player does not need much of his science to see how his gain has been made. When a clever bumble- puppist craftily leads a singleton and rejoicingly makes his rutf, the scientific player knows just how it has happened that through that too clever dodge three or four tricks have come to him which otherwise he would never have made. If Mr. Ram has ace, queen, and a small one of a suit, and the eleventh round has come, the enemy on his left holding (to the knowledge of every observant player at the table) king, knave, and a small one, he makes his bird in the hand the ace, lamenting only his bad luck, not his feeble play, when two tricks go to the enemy ; but if, under like circumstances, a correct player leads the small one, and on the return of the suit makes both the ace and queen, nothing will persuade the un.skilful player that the result came from no groping in the dark, but was simply inevitable, and as obvious beforehand to the sound player as the sun in a clear sky. Even if by some amazing chance one can show a player of this sort that in such a case scieitce has saved a trick which nescience would have thrown away, he cannot see the importance of the point. " A trick here, or a trick there, what can that matter ? " he will say. " Why, you yourself admit that by bad play a trick may be made which sound play would have lost. One set of casual tricks balances the other — for anything you can tell," and so forth. But that is just what science knows not to be the case. The scientific whist player can look on complacently when bad play wins a trick here or a trick there, knowing that in the long run all -siich gains are balanced by corresponding losses ; the scientific whist player can in like manner com- placently see play which he knows to be best five times out of nine, turn out badly four times for every five times that it turns out well ; but .science knows assuredl)' that every trick made by s ientific play where unsound play would have missed it, is so much to the balance of gain which in the long run is bound to stand out beyond the gains and losses either way depending on the mere run of the cards. As regards his closing remarks, that authorities dispute December 1, 1»»7.J KNOWLEDGE 00 over the scientific principles of whist, I need only say that Mr. Ram must be quit* unacquainted with the literature of the game. There are not two opinions on any one of the leading principles of whist play. The questions which Mr. Ram has seen discussed have had about as much to do with whist science as a discussion about the best pattern for the backs of cards would have had. All the discoveries which various writere on whist have claimed to make have related to methods of indicating the nature of the players' hands without actually showing the cards. The science of whist indicates the best way of playing such and such canls under such and such conditions. Experience and practice enable good players to infer where the cards lie, and so to ascertain under what condition they are pursuing their strategy. "Methods have been devised (more or less recently) for showing certain details of a player's hand independently of inferences based on his strategy. The differences of opinion which have arisen i-especting these methods relate to no principles of whist science, but to the questions : First, whether the game is improved or impaired by devices which tend to assimOate it to doable dummy ; secondly, whether the gieater advantages which skilful (as compared with unskilful) players may gain from such devices are fair advantages ; and thirdly, whether, with players of average skill more is gained by informing partner about details of one's hand, than is lost by giving the opponents that infor- mation. The fact that I am bringing out in these columns the whist science of old Mathews as well worth studying by modern players, shows how little the principles of scientific whist have changed since Mathews' day. But I am no more at issue with any of the leading whist-playei-s of to-day about whist principles than I am with ^Mathews or his pre- decessor Iloyle. ( Here and there views have changed about some detail or so, depending on nicely balanced chances — as in the ca.se of the old lead of Queen from Queen, Knave, nine, now only adopted on special occasions, and in regard to covering an honour with an honour second hand ; but I have been speaking of leading principles.) With regard, however, to the signalling methods now in vogue, and little likely to be given up, I certainly hold strongly now by the opinion that, though they have introduced no new scientific principles (nor have been advanced, I suppose, with any idea of changing the principles established of old), they have greatly injured whist as a recreation. Weak players have become i-elatively weaker since they consented to let these signals be introduced — precisely as they would become relatively weaker still if they allowed kicking under the table, significant coughing, sneezing, drumming, and the like, to be adopted as systems of legitimate signalling. They would become weakest of all if a kind of whist were introduced which would be the most diflicult and the most scientific game of all — whist in which all four hands were displayed as they practic;\lly are in double dummy, but four plaj'ers were engaged as in coijimon whist. This, by the way, would be a magnificent game so far as its dependence on skill was concerned ; but as a recreation it would be altogether inferior to whist as ordinarily played. Lastl)-, I may remark on the idea underlying Mr. Ram's letter, that where there is chance there can be no science, bec;uise there Gin be no exactitude. Science seldom secures exactitude, though it strives after it. But if there is a subject about which science is exact, it Ls in the existence of law in chance results. A game depending on the throw- ing of dice may be a pure chance game in one sense ; but the player would come out badly in such a game who should fail to recognise the exact scientific value of the chances involved. WATCHED BY THE DEAD. OW in " Edwin Drood," the first part of the stoi7, that Ls the part which ends with the disappearance of Edwin and the close of the sequent inquiries (constituting the first six- teen chapters), forms but one-third of the book as left by Dickens. Had no more been written more might still have been guessed as to the interpretation of the mystery than could have been readily guessed about the " Moonstone " mystery if only the first part of Mr. CoUins's story had been completed. Apart from the feeling, not to be explained or communicated, which assures those who undei stand Dickens's manner and know the meaning of his tones, that Drood is not dead though changed, there is clear evidence not only that Drood is alive, but that Grewgious knows Drood is alive. We will note first what every reader ought to note, though somehow it has been overlooked by many ; we shall then touch on a circumstance which might naturally enough escape notice, though when once noticed it is decisive. Grewgious is not a suspicious man, though keen and observant, with a very strong sense of what is just and right. He had had no suspicions of Jasper. The interview between him and Ja-sper in Chapter IX. — the last before the disiippearance of Drood — is perfectly friendly. Xay, Grewgious. a man who could not pay compliments, says in that interview, " Come, Mr. Jasper ; / know //our affection for your nephew, and that you are quick to feel on his behalf" When Jasper accepts the compliment " with a friendly pressure of the arm," Mr. Grewgious "nods his head contentedly." He shakes hands in the most friendly way with Jasper at paiting, though rather quickly correcting Jasper's " God save them both " into " God bless them both." Contrast this with Mr. Grewgious's behaviour when next they meet, and we feel at once that Grewgious has learned, somehow, that Ja.sper is the wretch we know him to be — or, as he puts it later, that Jasper is a wild beast and a brigand. A verv short time has passed since their friendly interview ; nothing has ostensibly happened to shake Grewgious's confidence that Jasper loves Edwin Drood ; and Grewgious Ls understood to have every reason to regard Jasper with special sympathy. For Jasper's well-loved nephew is sup- posed to have been murdered ; and for many hours Jasper has been " working and toiling " to find traces of his nephew — "now in barge and boat, now ashore among the o.siers, or tramping amidst mud and stakes and jagged stones in low- lying places, where solifciry watermarks and signals of strange shapes showed like spectres." He has just returned home exhausted — "unkempt and disordered, bedaubed with mud that had dried upon him, and with much of his clothing toi-n to rags." Surely a man to be very much pitied by Grewgious, who " knows his affection " for the missing man. Nothing but absolute certainty that Jasper is a murderous villain could now prevent Grewgious from showing him such sympathy as even Crisparkle, angry though he is at the suspicions cast on Neville Liindless, does not refuse. (It is important to notice that Mr. Grewgious knows little or nothing about Neville.) So far, however, from showing any sympathy with this unkempt, exhausted, and miserable man, Grewgious is curtly abrupt at the very beginning of the interview, and shows a hardness and cruelty to Jasper as it proceeds such as nothing but the absolute certainty that he sees Drood's would-be murderer before him could justify. Grewgious, who knows scarcely anything about Neville, has no special reason to be angry at suspicions cast upon that young man. Yet every word" of Jasper's implying suspicion of Neville, however indirectly, is sharply corrected. " Have you seen his sister ? " 36 ♦ KNOWLEDGE ♦ [December 1, 1887. Jasper asks, Neville's name not having yet been mentioned. " ]V7iose t " asks Grewgious, curtl}' and turning his eyes with exasperating coolness on Jasper's face. " The suspected young man's," Jasper replies. " Do you suspect him t " Grewgious asks. But even this is little. Grewgious has come to tell Jasper that which, if Jasper were innocent, would only interest him, and would certainly not be particularly distressing in the midst of the intense anguish and suspense Jasper is supposed to be enduring — viz. that Edwin Drood and Rosa were no louger betrothed when Drood disappeared. Only if Jasper had murdered, or supposed he had murdered, Drood, because of a furious hatred of his nephew as betrothed to Rosa, would the information have any special siguificance at all. But if that were so, it would indeed be a terrible blow to Jasper. It would not only show him that he had plotted, and so far as he knew carried out his murderous scheme, against a man of whom he had no reason to be jealous, but that actually his murder had helped to remove an obstacle from the path of a more dangerous rival. Now, if we merely note that Jasper receives Mr. Grewgious's news with horror, we find nothing particularly significant in this scene. But there is much more in it. Grewgious kiioios that his news will be received with horror. He warns Jasper of this, and even offers to put off the communication till the morrow, possibly because he feels a pity for the weary wretch before him, vUlain though he knows Jasper to be. But as Jasper concentrates his attention to listen, Grewgious resumes his determination, " with compressed and determined mouth, now," he looks at the fire, as with provoking slowness and " internalness " he opens the statement. As he reaches the part w-hich will move Jasper, Grewgious " looks fixedly at him sideways." Jasper's face grows ghastly before him ; but he has no com- punction. Sentence by sentence he strikes the wretch, till at last he " saw no ghastly figure, sitting or standing ; saw nothing but a heap of torn and miry clothes upon the floor." " Not changing his action even then, he opened and shut the palms of his hands as he warmed them, and looked down at it." If Grewgious did not know him for the murderous wretch he was, his treatment of Jasper here, and after- wards, is sheer brutality ; yet Grewgious is a kindly man and a gentle. It is absolutely certain, then, from this scene alone, that Grewgious knows what Crisparkle, Neville, and the rest do not know, or even suspect, that Jasper himself has striven to murder, and in intent has murdered, Di'Ood. From whence can Grewgious have learned this? He might have learned some few facts from Rosa which would suggest suspicion — as that Jasper was jealous of Drood, that she herself had an indefinable and inexplicable dread of her music teacher, nay, that she had striven to warn Drood against Jasper. But even if we were not clearly told in Chapter XX., six months after the disappearance, that Ro.sa was ashamed of her own suspicions (mistakenly judging of Jasper's conduct by such rules as might apply to average men, but not to " a horrible wonder apart," like him), we should be sure that nothing which so delicate and sensitive a mind as hers could have communicated to Grewgious would have sufficed to convince him that Jasper was Drood's murderer. The knowledge of which Grewgious made such terrible use might, of course, have come from Rosa; it would, indeed, have very naturally been imparted to him by her : but his knowledge that it would torture Jasper, his certainty that Jasper deserved to be so tortured, his manifest conviction that Jasp?r was a murderous villain deserving no mercy, these could not possibly have been de- rived from anything Rosa had said to him. We might interpret part of Grewgious's conduct, indeed, by supposing that while he had learned from Rosa about the breaking off of the engagement, he had also discovered that Drood had been murdered, and murdered by Jasper. This, of course, might easily have happened. Durdles, with that curious gift of his, by which he could tell when there was anything inside a tomb (a gift enabling him, in one specified case [see Chapter V.], to find how one of his workmen had left some rubbish in a six-foot space inside a tomb), might well be supposed to have discovered Drood's body, and the quick- lime cast over it by Jasper, on the very night of the murder (assumed, on this view, to have been accomplished), and he might have brought to Grewgious convincing evidence that Drood was killed, and that Jasper had done the deed. This would account for everything we have thus far men- tioned. But this explanation must, for another reason, bo absolutely rejected : it will not hold water for an instant. If Grewgious (to say nothing of Durdles) knew that Drood was dead, even without knowing further that Jasper had killed him, he would assuredly not have let the matter rest here. He is a man singularly obedient to the dictates of duty ; and he would know that duty imperatively required him, in the case supposed, to make known such facts as this explanation assumes him to have learned. It would have been utterly inexcusable, nay, it would have made him an accessory after the fact, and have been justly punishable as a crime if he had not brought his knowledge at once to light, while the evidence which had satisfied him still remained available for the purposes of justice. We may set the idea utterly on one side that Grewgious knew Drood to have been actually murdered by Jasper. Since it is certain that Grewgious, during this remarkable interview, knows Jasper to be a murderous villain, while it is equally certain that he knows Jasper is not actually a murderer, nothing remains but that we should conclude that Grewgious knows Drood to be alive while he also knows him to have been murderously assaulted by Jasper, nay, flung into the tomb, after the jewellery so well known to Jasper had been removed. Grewgious would know also that Jasper supposed he had heaped quicklime over Drood's dead body, so that all trace of that body and of its clothing might in a few hours be destroyed. For we know this to have been part of Jasper's plot ; and manifestly Grewgious knows everything Jasper had plotted. While thus, and thus onl;/, can Grewgious's conduct be explained — his torturing Jasper without compunction, on the one hand, and his not striving to bring him to justice on the other — we find here the explanation of a little detail which no one seems to have specially noticed, though it is singularly significant — in fact, absolutely decisive. Just before Drood vanished, Grewgious had entrusted to him a ring which was the sole memento Grewgious had of Ro.sa's mother. He had loved her, and loves Rosa because she reminds him of her so strongly. He could hardly bear to part with the ring, even to Rosa. " It was hard," he says, " to lose the ring, and yet it must have gone from me very soon." For it was to be given to Rosa on her betrothal. But he charges Edwin solemnly, " by the living and by the dead," to restore the ring to him if Edwin's engagement to Rosa is cancelled. " Will it come back to me 1 " he asks lumself .sadly, when Edwin has taken it away. " My mind hangs about her ring very uneasily. But that is explainable. / hare had it so long, and I have prized it so much/" (All this means, for all who understand Dickens, that the ring is presently to be in danger of disappearing.) That ring was not given to Rosa. " Let the sorrowful jewels be," Drood said to himself. He would i-estore them to Rosa's guardian " when he came down ; he in his turn would restore them to the cabinet from which he had unwillingly taken them." " Let them be ; let them lie unspoken of in his breast. . . . Among the niighti/ store of wo7ider/ul chains that are for ever forging, day and night, in the vast iron- December 1, 1887.] ♦ KNO>ArLEDGE ♦ 37 toorks of' time and circumstance, there was one chain forged in the moment of that sin/tU conclusion, riveted to tlie founda- tions of heaven and earth, and gifted irith invincible force to hold and drag." Grewgious knows that the ring he so prized has not been given to Rosa. He knows it is not among the jewellery found by Crisparkle in the river. Yet he says nothing I He neither causes .search to be made for jewels which were of such interest to himself, nor does he say aught which would lead to this particular clue being so followed that perhaps by its aid the murderer might be brought to j ustice 1 We venture to say that Dickens had made no such blunder as this view would imply. It was not without a special purpose either that he dwelt on Grewgious's sorrow and anxiety about the ring, or that he directed the reader's special attention to the ring as eventually to lead to the detection of the criminal. He himself had tliat ring in his thoughts throughout all the circumstances following Drood's disappearance. He must also have known that though careless readers might overlook the ring, or at least the interest of Grewgious in it, some among his readers would assuredly notice the point. Grewgious is not careful about the ring, or about the detection of the supposed murderer, siinph/ because he has the ring back in its cabinet, and because he knows of Jasper's attempted crime, and of Jasper's stroke having failed of its aim. He says in Chapter XXII. he " holds decidedly that John Jasper is a brigand and a wild beast in combination." Such a man as he would have said nothing like this unless he had known of Jasper's muiderous assault on Drood, and of his being to all intents and purposes a murderer. Such a man as Grewgious would assuredly not have suffered the prized relic of his lost love to be in the hands of a villanous wretch like Jasper, or to disjippear without an effort to trace it. But he could not have leai'ned anything about the ring, nor could he have learned aught about Jasper's villany, except from Drood himself (for, as we have seen, the mere discovery of Drood's body with the ring upon it is not an admLssible explanation). So much established — beyond, we think, any possibility of question — the explanation of " the Datchery assumption " is no longer difficult. But we believe that this assumption, to use Dickens's own word, can be interpreted independently of the decisive evidence obtained from the behaviour of Grewgious. We know that the very last reference by Dickens to his story was an expression of anxiety lest, in the treatment of the Datchery assumption in the last chapter, he should have shown too clearly how the stoiy was to be developed. We think the fear was fully justified. For we cannot see how any one who understands Dickens's manner can read that last chapter without being convinced that Datchery is Drood. In the earlier part about Datchery there was more care to conceal his identity. Even a fairly careful reader might doubt whether the character were an assumption at all — except, perhaps, for the obvious fact that Datchery wears a wig of white hair, and 'the probable circumstance that the eyebrows are dyed black (or they would hardly have been mentioned). Even though the careful reader may decide that Datchery is disguised, he would scarcely be led to conclude that Datchery is Drood, clearly though he may have seen that Drood is not dead. Dickens artfully makes Drood inquire about Mr. Tope as if he knew nothing of the verger, and still more artfully makes Drood lose himself on his way from " the retiring Grozier " to Jlrs. Toj)e's rooms. Of course the inquiry corresponded well with Datchery's obvious wish to conceal his identity ; while Drood's losing his way, even if not regarded as part of the same plan, would be only too ea.sily understood by any one who has resided in a cathedral town and knows how readily one may get " very cold indeed " in the search for even a well-known nook from an unknown hotel " of retiring disposition " like the Crozier. (We know Rochester — Cloisterham, that is — pretty well ; but we would certainly not undertake to find our way easily through all its labyrinthine passages.) Of course, with the knowledge that the Datchery character is an assumption, as Dickens told Miss Hogarth later, even the scenes in Chapter X VIII. suffice to show who Datchery is. Thei-e is no one in the story but Drood himself un- accounted for, except only Bazzard. NowBazzard is not only a fool, but a dull one, and a curmudgeon ; Datchery is neither the one nor the other. Bazzard has no sense whatever of humour ; Datchery is full of dry fun. Bazzard is as clearly intended to come to utter grief in the end as was Silas Wegg in " Our Mutual Friend ;" Datchery is just as clearly intended to triumph in his plans. One might almost as reasonably imagine that Datchery is Honeythunder as that he is Bazzard. But in the last chapter of the book the evidence that Datchery is Drood is so clear that no one can doubt its meaning, though many may overlook its existence till it is pointed out. We would in particular invite all who love the writings of our later " Wizard " — the Wizard of the South — to com- pare very carefully the scene between the opium-eater and Drood in Chapter XIV. and the scene between the same oiHum-eater and Datchery in Chapter XXII 1. It would not be fair for lis to quote, as we might do, sentence after sentence from one scene for comparison with sentence after sentence from the other. Let the reader who has not yet done this do it for himself; he will be well repaid. The close resemblance between the characters of Drood and Datchex-y will at once be obvious ; the humour and the pathos of each will be fully appreciated. Of course, we compare Datchery only with Drood as seen in that last scene before the disappearance, when sad after his parting from Rosa, whom he loves — -though even then he does not know it, " the vanity and caprice of youth " (soon to dis- appear for ever) " sustaining the handsome figure of Miss Landless in the background of his mind." The Drood of the eai'lier scenes is dead — " Poor youth, poor youth," Dickens says of that Drood ; and many readers suppose he has condemned Di'ood altogether to death. But the closing passages of the two scenes must be quoted to show how absolutely identical are the tones ' in which Drood and Datchery are spoken of, though of course we cannot make this clear to those who have no ears for such tones : — From Chapter XIV. This is not an inspiriting close to a dull day. Alone, in a seques- tered place, surrounded by ves- tiges of old time and decay, it rather has a tendency to call a shudder into being. He makes for the better-lighted streets, and resolves as he walks on to say nothing of this to-night, but to mention it to Jack as an odd coincidence to-morrow; of course only as a coincidence, and not as anything better wortli remember- ing— still it holds to him, as many things better worth remembering never did. He has another mile or so to linger out before the dinner-hour ; and, when he walks over the bridge and by the river, the woman's words are in the rising wind, in the angry sky, in the troubled water, in the flicker- ing lights. There is some solemn echo of them even in the cathe- dral chime, which strikesa sudden surprise to his heart as he turns in under the archway of the gate- house. From Chapter XXIII. Mr. Datchery pauses with the selected coins in his hand, rather as if he were falling into a brown study of their value, and couldn't bear to part with them. The woman looks at him distrustfully, and with her anger brewing for the event of his thinking better of the gift; but he bestows it on her as if he were ahstracting his mind from the sacritice, and with many servile thanks she goes her way. John Jasper's lamp is kindled, and his lighthouse is shining when Mr. Datchery re- turns alone towards it. As mariners on a dangerous voyage, approaching an iron-bound coast, may look along tlie beams of the warning light to the haven lying beyond it that may never be reached, so Mr. Datchery's wist- ful gaze is directed to this beacon and beyond. 38 ♦ KNOWLKDGE ♦ [December 1, 1887. Rightly to understaud the force of the resemblance between " the two scenes, of which these passages are the close, it must be remembered that if Datchery is really Di-ood. then in each scene we have the same person ; in eiich scene Drood shows the same kindly and considerate way of talking to the old and feeble (" always kindly," we aie told of Drood ; and as kindly to the child as to the aged, if Datchery is Drood), in each Drood has been reminded by the old opium-eater of his love for Eosa ; in the first he had just made the sacrifice of that plighted troth which he had but then learned to value; in the second his thoughts were on that sacrifice — no other — when the old woman thought he was weighing the value of a few coins ; in one scene he has a foreshadowing of the danger to be feared from Jasper ; in the other he knows the danger he has to face in exposing Jasper for the ^-illain he is. We can understand, then, how it comes to pass that the selfsame tones are heard in both passages throughout both scenes. Even the old opium-eater somehow felt, she knew not how, that the white-haired man addressing her was no other than the " young gentleman " she had met there before.* We must not be duller-witted than she was. Note, further, that when Datchery had met Jasper without being detected, he regarded that as a ditficult task achieved — •' For a single bufler, living on his means," he said, " I have had a rather busy afternoon." But after the scene with the old ojsium-eater, he says of his work, " Hum I ha I a very small score, this ; a very poor score." Albeit, when he finds that she has, like himself, a strong feeling against Jasper, he adds "a thick line to the score, extending from the top of the cupboard door to the bottom," and falls to " on his breakfast with an appetite " — these being the very last words of the story, and signifiamt words they are. Some other points disclosed in the story as written may be noticed here, though, in truth, it would be easy to fill a volume with the consideration of the multitudinous touches introduced by I)ickens into this only half-written novel. It is clear that Kosa knows perfectly well that Drood is not really dead. Of course, Grewgious would not let Jier for whom he had such tender and chivalrous feelings remain a moment in doubt on this point. But, apart from that, her whole conduct is inconsistent with the belief that she is as troubled by the mystery of Edwin's disappearance as she certainly would have been, sensitive and tender-hearted as she was, had it really been a mystery to her. Even the way in which she speaks of Jasper to Grewgious as ''his uncle," shows that they both think of Drood as a living man. But this is shown even more clearly by the very passages which some regard as suggesting that she sorrows for Edwin as dead. When she is first beginning to be in love with Tartar she thinks of Edwin, saying, " Poor, poor Eddy 1 " Now, had she formerly loved Edwin, the newly-born love for Tartar, Edwin being dead, would have suggested this thought, naturalh' enough. But as she had never felt more than a sisterly love for Edwin, it is clear there is another meaning in her sorrowful thought of him : and what else should it be but the thought that nuw there is no hope for * It was no new idea of Dickens's thus to picture the unconscious influence of individuality making itself felt through all disguise, through all real change of condition. We have already noticed one case — viz. where Mrs. BofBn somehow feels that John Harmon, whom she had last seen and known as a child, is near her, when the realJohn Harmon is there disguised as the secretary, Rokesmith, and now a man who, though still young, has been made serious and grave by many sorrows. And there are many other e.'iamples. Of course we are carefully told that the old woman was reminded of the former meeting with Drood "by the sight of the place " But this is only to blind us as far as possible to the truth that she recalls the former conversation, because, changed though he is in appearance, she is talking to the ven- man with whom she talked before. Edwin that she ever can love him. She knows Edwin is alive ; she knows that Edwin loves her ; she has heard this through Grewgious, and has even promised Grewgious (pro- bably) that if ever the time should come when she may feel love for Edwin she will sa\' so. When she comes to Grew- gious after Jasper had terrified her, and has begun by saying that " she had taken a sudden resolution," she remembers this promise, and, lest Grewgious should think the sudden resolution related to Edwin, says in the same breath, " Poor, poor Eddy ! " — an exclamation which the keen old man is not at a loss to understand, as we note by his sympathetic response. And every expression of regret for Eddy on Rosa's part will be found to relate to her dead love for him, or rather for the love that had never lived. How, then, was the story to have ended ? It appears to us that, independently of what Dickens said to Forster on this point, the end is very clearly foreshadowed. Of the four men who are in love with Rosa, two are to die. Jasper will be driven to the tomb where he supposes Edwin's dust to lie, to seek for the ring of which in due course Grewgious will tell him.* There, seeing his supposed victim (as the outside picttu-es of the original monthly numbers show Edwin I)rood) standing alive and threatening, he w-o\ild fiy with a shriek from the menacing vision, as he would con- sider it, to be pursued by Neville, Tartar, and Crisparkle (as also shown on the cover) up the \\ inding stairs along which he had led Drood a year before to his doom. In this pursuit, or rather in the attack on Jasper, Neville was to be slain. (No character in all Dickens's novels was ever more distinctly doomed to death, by the clear evidence of the narrator's tones, than Neville Landless.) The death of Jasper was, we conceive, to have been like that of Jonas Chuzzlewit and of Slinkton in " Hunted Down ; " Rosa was to marry Tartar ; and Helena, Crisparkle. We imagine that Dickens would have found noble exercise for his special powers in showing Neville Landless rejoicing in the happy fortune of Tartar's love for Rosa, though he had viewed so angrily Edwin's seemingly prosperous love, in the days when Edwin was not in earnest and did not even know the love that was in his heart. Edwin was doubtless to remain to the end devoted to Rosa, even as Grewgious had remained devoted to the memory of Rosa's mother. There was to have been no bitterness, however, in Edwin's heart towards Tartar in regard to his own less fortunate love. A certain wistfulness such as we see already in Datchery, and on Rosa's part a certain sad regi-etfulness — nothing more : nothing to pain those who had followed Edwin's story, more than we are pained by the gentle tenderness of Tom Pinch's love for Mary Chuzzlewit— a love as tender and as pure as his love for her as Mary Graham. OvSTER-OPEXlss MosKET. — Mr. Alfred Carpenter, of the Marine Survey Office. Bombay, has observed Macacus monkeys on the island off Sniith Burmah opening oisters with a stone. Ttey bring the stones from high-water mark down to low water, selecting such stones as they can easily grasp. They effect the opening by striking the base of the upper valve until it dislocates and breaks up. They then extract the oyster with the linger and thumb, occasionally putting the mouth straight to the broken shell. The way they have chosen is the easiest to open the shell. * In the singularly amusing conversation between Grewgious, Oisparkle, and (eventually) Tartar, a conversation in Dickens's best style, Grewgious, in advising that the caller (Tartar, as it turns out) shall be admitted, remarks that it is well ti take advantage of any such opening as may present itself. " I could relate an anecdote in point," he says, " but that it would be premature." It is impossible to say what this refers to, but one may guess that perhaps Grewgious when in Cloisterham had looked in at fhe jeweller's who had talked with Drood about his jewellery, and from him learned (what Drood had learned") that Jasper had a most exact knowledge of all Drood's ornaments. This would have suggested the power of the ring to hold and to bind the guilty wretch. December 1, 1887.] KNOVy^LEDGK ♦ 39 A STUDY OF CHILDHOOD. 3HE profoundest philosophers of our day have not thought it beneath them to discuss matters which are commonly legarded as outside the domain of science, in a trul}' scientific spirit. Faraday analysed a tear ; Darwin has based important theoretical views on the analysis of a smile, a frown, a sneer, a gesture of hand or head or shoulders. Darwin noted in particular the expression of the emotions in very young children — a subject of inquiry of extreme importance when it is considered that, according to the Darwinian theory of the origin of man, we should find in very young children the strongest indications of those characteristics which link the human race with races next below them in the animal world. In the unborn child may be traced the various stages of progress, from the ascidian to fish-like and thence to reptilian forms, and so onwards to the lower and thence to the higher mammalian type. The newly-born child shows in many chai'acteristics, which disappear with advancing years, his kinship to the most advanced mam- malian type short of man. As tiine passes, the simian characteristics are replaced by those which are now recog- nised only in uncivilised races — the progression not ending in infancy, however, or even in early youth, but (at any rate with the best representatives of civilised races) continuing into middle life, i^ince our kinship with savage human races is not questioned (though for aught that appeal's it might very well have been doubted, and is, indeed, as it is, altogether misundei-stood by many), there is more scientific interest in the study of the very young child, whose move- ments and characteristics, carefully observed, throw clearest light on the question of man's kin.ship with the higher mammalian types. Hitherto the mental and physical development of very young children has not been .systematically studied. Tiede- mann, in the last century, gave some attention to the sub- ject, but his work has little value in the present day.. In a work of some 4-10 pages, Professor Preyer, of the University of Jena, made the first three years of a child's life the sub- ject of careful and systematic study. He carefully con- sidered the progress of the child from week to week, or the apparent cessation of progress in various parts of the child's development, and attempted to explain the various phenomena successively observed. It is hardly necessary to say that the standpoint from which Professor Preyer observed and made his inferences was that of the evolu- tionist. Aided by his studj- of the ways and habits of the young of lower forms. Professor Preyer anah'sed the phe- nomena of the infant mind with a success which perhaps he otherwise would hardly have been able to achieve. Professor Preyer worked on a single suhject — a boy of his own. Here, at the outset, it is to be noticed that while many of his observations may be such as would have been noted in other cases, perhaps in all, observations made on one child c-t have been some judg- ment of distance and direction here, because his eyes could not guide the capture, as when it was made with the hands. Hearing is defective for several days after birth. Young mothers should note this, by the way. I have known cases where a mother has feared that her child was born deaf because it paid no attention to noises not accompanied by movements it could feel. In one sense every infant is born deaf, owing to the condition of the aural conduits : and even when the organs of hearing are no longer impeded there is often no power of discriminating .sound for several days. Professor Preyer found, he says, that "the first un- mistakable movements of the head in the direction of a sound occurred in the eleventh week." (This seems not quite consistent with his statement that on the eii;hty-fii>t day the child tried to look at a drinking-glass which was emitting sound.) At the end of the sixteenth week the movement of the head in the direction of a sound — that is, so that the eyes were directed towards the spot whence the sound came — " had attained the precision and certainty of a reflex movement." The sense of feeling is next dealt with by Professor Preyer. His observations .seem to show that the surface of the body is somewhat less sensitive to touch just after birth than it afterwards becomes. So also the difference of sensibility in diflerent parts of the body incre^ises for soiie hours after birth. Immediately after birth the body seems almost insensible to variations of temperature, but soon becomes tolerably keen. Thus, when the bath was cooled down to 32i° centigrade (90i° Fahrenheit) the child appeared content, but with a further lowering of 1^° centi- grade (2j° Fahrenheit) the child began to cry. The most perfect sense at birth is taste. " The discrimina- tion of quality, namely, sweet, bitter, salt, and sour, is possible from the fir.st, provided sufliciently strong stimuli are employed. If weak solutions are iLsed the tactual sensa- tion overpowers the gustatory, and the child is indiflerent." The sense of smell seems at first to be associated with the sense of taste. In the seventeenth month, when a hyacinth was held to the child's nose, the youngster tried to fcike it into its mouth. It is not altogether clear, however, that the sense of smell is distinct from that of taste. Professor Preyer considers that the first odour known to the child, that of its mother's milk, is so inseparabh' bound up with the pleasure of feeding and the sense of taste, that the child argues in this case the smell is pleasant, therefore this is something nice to eat. But the senses of touch and sight are involved here, and it seems to me, from what I have observed in a great number of cases, that they have at least as much to do with the child's attempt to eat what is offered to it as any sweet smell the hyacinth might have had. If a piece of twisted paper, or a ball of cotton, is held to a child's nose, he will take it into his mouth, tho\igh it has no odour, pleasant or otherwise. This habit continues to the middle of the second year, or even later, though after the first eight or nine months the child's wish seems not so much to taste as to test the object presented to it. Professor Preyer considers tliat fear is an inherited instinct with young children. Of this there can be very little doubt ; though it is to be noticed that children in the same family differ very much as respects timidity, both in regard to the degree of fear they show under the same con- ditions and to the circumstances which chiefly aflfect them. In some cases fear doubtless results from association, and may often be ludicrously out of proportion to the exciting cause. A boy of mine who during his first teething bad been in charge of a strange nurse, showed .■■igns of anxiety afterwards when she approached, as if (but of course the interpretation may not be correct) he associated her appear- ance with the pain he had sufl'ered when he first saw her. Professor Preyer says that " the timidity of young children before small animals can only be explained as the result of inheritance." He noticed this first in the ninth month, " and as late as the thirty. third month the child cried in a ludicrous manner at the approach of a puppy only a week or two old." The timidity, here, is rather anxiety in the presence of the unknown and mysterious than an inherited fear of small animals. I have noticed that an anxious, half- frightened (but also half-curious) look always comes over a child wlien it sees, hears, or feels anything of a striking nature for the first time. Professor Preyer points out that blinking the eyes on the sudden approach of an object does not necessarily imply an intensified fear of danger. It seems rather to be a result of experience, not being noticed during the first two months, and is therefoi-e presumably an acquired habit. But he regards the fear of falling when the child begins to walk as instinctive. Here, it .seems to me, he is in error. If the fear of falling were instinctive, we should, I imagine, see more trace of stich fe^r in very young children when they are held high in the air, and still more when they are tossed up (as some will unwisely do with their children) to the ceiling. But this is not usually, or indeed generally, the case. I hold my youngest boy high up above the gi'ound, and he only crows with pleasure. I let him down suddenly from that height, and he shows no signs of fear, only a sort of quaint perplexity at the sudden change of position. So, again, I agree with Sir. Sully in thinking that the timidity displayed by Dr. Preyer's little boy in the twenty- first month, when the child was taken close to the sea, is an inherited fear. As Mr. Sully well remarks : " Much of children's early shrinking is undoubtedly due to a kind of shock which is given by certain things. One may easily suppose that the vast expanse of water, especially when attended by movement and the peculiar voluminous .sound, would produce such an efleet ; and it is certain that some- thing of children's fear of animals, especially of dogs, is December 1, 1887.] ♦ KNO^WLEDGE ♦ 41 occasioned by shoct. A boy of mine showed very decided and strong fear," proceeds Mr. Sully, " amounting to childish terror, at dogs, after one of these animals, which had secretly entered the room with his mistress and ensconced himself under the table, suddenly ran out towards the child, barking. ' Bow-wow ' remained for months after the type of every- thing new and disconcerting. When hearing a strange sound he would run to his mother and hide his face, ex- claiming ' Bow-wow 1 ' He showed a dislike to worms, which he also called 'bow-wow.' I think that there is no doubt that inheritance played a part here, but something must be allowed for the mere disturbance of the shock. The fact that a child may be completely upset by the father or mother donning a slight disguise seems to me to point conclusively to this. Dr. Preyer's facts on this head are interesting, but hardly full enough. There is no reference to the seemingly whimsical timidities of children towards strangers. My observations have convinced me that there are certain peculiarities of face and tone of voice which at once rouse strong fears in the child ; and M. Perez and others have pointed out that young children shrink from persons dressed in black. Would Dr. Preyer say that these are cases of an inherited association 2 " MOVEMENTS IN THE STAR DEPTHS. I^^IONG the many contrasts between the seem- ing and the real presented by the teachings of astronomy, there is not one more sur- prising than the contrast which exists be- tween the seeming fixity of the stars and the tremendous velocities with which in reality ever}- star is urging its way through space. For wluit evidence could be more convincing, it would seem, than that which the study of the heavens has aflbrded in support of the theory that the stars are fixed ? Thousands of years ago the constellations are as the}' now are ; Orion with its belt, the seven stars of the plough, Cassiopeia's chair, the garland of stars in Perseus, the Pleiades and Hyades, all the principal star groups were figured by ancient astronomers as we should figure them now. Where else can we find such stability I And if, in thousands of years, the star groups have not changed in form, how can we reconcile the evidence of fixity with the a.ssertions of astronomers that all the stars are in rapid motion, and some certainly moving so swiftly that no form of motion known to us on earth is comparable with these tremendous velocities? The answer to these questions is exceedingly simple. Indeed, the whole subject of the stellar research depends on very simple conditions ; for the magnificence of the problems involved prevents the astronomer from dealing with any but those more striking features which can be considered with- out the use of complex or recondite methods. The fact is, then, simply this, that the stars are so far off that their motions, though inconceivably swift, produce no change of place which ordinary observation c;xn recognise. The effects of motion arc reduced by distance, precisely as the dimensions of an object are reduced. As a ship on the horizon, though she may be urging her way swiftly through the water, yet seems at rest, so the distant stars seem un- changing in position, though in reality they travel many miles in every second of time. It is indeed worthy of notice that the effect of the enormous distances of the stars in diminishing their apparent motion is the exact counterpart of the effect of the same distances in preventing any appreciable stellar displacements on account of the annual motion of the earth in her wide orbit. These two circumstances correspond in every respect. We read with astonishment in our own books of astronomy that, though the earth's orbit has a span of 185,00(1,000 of miles, yet even the nearest star is seen in apparently the same direction (so far as any but the most delicate instru- mental observation is concerned) from opposite sides of this enormous path. But we should observe that it follows as a dii'ect inference that if a star travelled as many millions of miles athwart the line of vision it would seem to be unchanged in position, even though that star were the nearest in the heavens. So that we perceive at once how little reason there is for inferring from the aeeming stability of the star groups that the stars are at rest. The great marvel of all is that the groups remain unchanged in appearance during the year, though the earth shifts so enormously in position. That fact is the true basis of all our ideas respecting the vastness of the stellar measure, and once this vastness is recognised the wonder rather is that any stars should seem to move at all than that close telescopic scrutiny is required to detect stellar movements. If astronomers could only apply the same process for recognising stellar motions which they have to apply to examine the distances of the stars, we should know very little about the movements of the stars. It is not commonly known how little has been really done by astronomers to determine star distances. There are not four stars in the whole heavens whose distances have been satisfactorily determined ; and there are not twelve which, under the most rigid scrutiny, have given even the slightest signs of having a measurable distance. All the host of heaven, save these few, all the thousands of stars seen on the darkest and clearest night, all the millions revealed by the telescope, and all the millions on millions of them which no telescope yet made bj- man can reveal, lie at immeasurable distances. And yet the measuring line which has been used is of incon- ceivable length. A single length of it brings us to the nearest star. Alpha C'entauri, more than 200,000 times further away than the sun ; another length added brings us to two other stars, one lying in the Swan and another in the Great Bear ; and astronomers know pretty certainly that from thi-ee to ten or twelve lengths of this enormous line would give a distance within which lie all the twelve nearest stars. But they have no means of pushing their measui-ing rod further out into space. Not only can they not do so now, but it is unlikely that any improvements in telescopic construction will enable them to do so at any time. But the stars whose motions have been recognised are not some ten or twelve, but are counted by thousands, and there is every reason to believe that astronomy will one day count them by tens of thousands. The reason of this diflerence between the mastery which astronomers have obtained over one problem while its sister problem remains almost untouched is easily presented. To determine the distance of a star the astronomer must determine a diflerence in the star's direction, which is repeated oscillatingly year after year. If we imagine a line drawn from the star to the earth, the earth end of the line would travel round and round in a circle 18,^,000,000 of miles in diameter, the line itself swaying like a gigantic pendulum, and the effect to the observer on earth would be precisely as though the star were travelling round and round in a circle 18.5,000,000 of miles in diameter, a line from the earth to the star swaying like a gigantic pendulum. It is the sway of that pendulum that the astronomer has to measure, and how small that sway is will be understood when I mention that in the case of the nearest star it cor- respond.s to the motion of the minute hand of a clock or watch in the 200th part of a second. But in the case of a star travelling onward with enor- 42 ♦ KNO^A^LEDGE ♦ [December 1, 1887. mous velocity through space, it is not an oscillating but a continuous motion that has to be determined. In a year this motion may be less (and curiously very much less) than the annual swaying motion of the nearest star. But in the course of many years it becomes measurable or even (in the astronomical sense) considerable. We speak of the astro- nomical sense, meaning the way in which an astronomer considers displacements, which to ordinary observation are altogether inappreciable. With the telescope, magnifying such displacements several hundredfold, and also supplying the most delicate means of testing displacement, a change of place equal to the hundredth part of the moon's seeming diameter, instead of being barely discernible (as it certainly would be to the unaided vision) is a phenomenon altogether obvious and startling. Even so, however, by far the greater number of the stars move so slowly on the heavens that the lifetime of a single observer would be insufficient for an exact determination of a star's rate of (apparent) motion. There are some few stars indeed which are moving with abnormal rajiidity ; and these could have their rates determined in twenty or thirty years with great accuracy. Yet even among these the amount of change in an ordinary lifetime seems surprising small. For instance, the star which moves most rapidly of all — not a bright and conspicuous star as might be supposed, but a star so faint that it has not been thought worth while to give it a name in ordinary star lists — moves in sixty years over a distance less than one-fourth of the moon's apparent dia- meter. So that if an observer twenty years old noted the place of this star, and in his eightieth year observed it again, it would be that seemingly insignificant arc which he would have to measure — not to recognise such and such a dis- placement, but to measure its amount with accuracy. Of the real rates of stellar travelling we can form no exact ideas, simply because the stars' distances are unknown. There is a method by which the rates of stellar approach and recession can theoretically be determined ; but as yet it has not been applied with anything like exactness. It ap]iears proliable that the average rate of stellar travel is about twenty miles per second, a wonderful velocity if we consider that each star is a sun like our own, and that, like the rest, our sun, with his family of planets, is travelling with kindred velocity through space. By Richaed A. Proctor. I WRITE my Gossip for this month " by Susquehanna's side," at Wilkes-Barre, IPennsylvania, and in a hotel called "The Wyoming Centre." As I write, a wretched steam-whistle is sounding out the signal demanded by law when steamers on a river sight each other; but otherwise, as the shades of evening close over the scene, it is easy to conceive that in the days of the imaginary " (Jertrude " the valley of the Susquehanna looked much as it appears before me now, save for a very modern and business-like bridge just within sight on the right. * * * The story is a touching one as Campbell tells it. It is a slight matter that Wyoming is never pronounced Wy'oming, as the rhythm requires in the line On Susquehanna's side fair Wyoming ; but always Wyoming. Unhappily, there is a much more serious detail in which reality and the Gertrude story are at issue. Campbell remarks, and might with fail' reason have remarked, had he ever visited the Wyoming Valley, that " though the wild flower on the crumbled wall " and " ruined homes a sad remembrance bring " (so nearly as my memory serves me) " of what thy gentle people did beftd, yet thou," meaning Wyoming, "' wert once the loveliest land of all." It rather destroys the charm of the legend to learn, as is well known here " by Susquehanna's side," th.at of the three hundred and more who went forth to attack the Indians on that sad occasion, barely thirty were sober — all the sober ones, by the way, escaping with their lives. The descend- ants of the old settlers are a little sore when the real inwardness of the old Wyoming story is mentioned, though many of them mu.st of course be descended from the sober thirty. A CORRESPONDENT sends me a cutting from the Spectator, in which a certain explosive is described which can produce its full efl'ects without any heavy substance like cannon, mortars, or the like, from which it need be discharged. From a paper tubing it would be as effective as from a twenty- ton gun. Hence certain direful effects are anticipated for nations like the Swiss, who have hitherto owed their safety solely to the difficulty of conveying artillery into their mountain fa.stnesses. My correspondent asks whether such an explosive and such singularly " light " artillery are possibilities. They will become so when " action and reaction " cease to be equal and opposite; that is, never. * * * Another correspondent asks me whether I consider the influence of the moon on the weather worth the attention given to it in a recent number of Longman's Magazine. Since I consider the influence of the moon on the weather as nearly as possible nil, it should hardly be necessary for me to say that I do not. Regarded as superstitions be- longing to the old time when the moon shared with the sun and planets very potent influence over man, the fancies about the moon's weather significance are quaint and amusing enough. But it would be a waste of time to con- sider whether after all there may not be some meaning in them, since, without a single exception, they bear the clearest traces of their unscientific origin. * * * There is one lunar fancy only which has (though its inven- tors knew nothing of this) a quasi-scientific interpi'ttation. I refer to the notion that if the old moon is seen very distinctly in the new moon's arms wet weather will probably follow. As I pointed out many years ago, illumination of the moon by the earth, when, the moon being " new," the earth is " full " to her, must be to some degree greater when the earth's sunward face is cloud-covered — and as that face lies west of the observer's station when the new moon is seen in the west (the sun having recently set) we have in the bright- ness of the old moon in the new moon's arms a certain indication of cloudy skies west of the observer, whence usually weather travels. But those who know how per- sistently the old moon is seen clearly and strongly, even to the time of the moon's first quarter, in countries which have clear skies, while in hazy climes the old moon is seldom seen, must feel well assured that the distinctness of the old moon depends fiir more on clearness of sky than on any increase in the amount of " earth shine." * * * A CORRESPONDENT would like to see that explanation of an ice yacht's travelling faster than the wind, to which reference is made in my article on the curve in base-ball. In one of the first few numbers of Knowledge such an explanation is given. It may suffice to note here that with a strong beam wind, if an ice yacht travels no faster than December 1, 1887.] ♦ KNO'WLEDGE ♦ the wind, she is practically sailing 45 degrees or four points from the effective wind resulting from the combination of her own speed with the winds. If her speed is iacreased, she is sailing closer to the effective wind. But an ice yacht, which makes no way, and is little resisted bj' friction, can sail much closer than four points to the effective wind — in other words, her velocity will continue to increase long after she has attained a velocity equal to the wind's. Unfinished Worlds. By S. H. Paekes, F.R.A.S., F.L.S. (London : Hodder & Stoughton. 18S7.) — It is not, at first sight, very easy to see the raison J 'etre of Mr. Parkes's volume, inasmuch as he simply reproduces (not even always correctly) facts to be found in every modern work on popular astronomy extant. The most apparently obvious motive underlying his work would seem to be that of bolstering up Su- J. W. Dawson's weak and inept attempt to disprove the antiquity of man on the earth. But, having said this, we must in candour add that our author describes the objects of which he treats picturesquely enough, and that the perusal of his book by those approaching the consideration of its subject for the first time will be very likely to implant or stimulate in them a taste for the study of the heavens. We have said that 3Ir. Parkes is not always correct in his reproductions of astronomical facts, in Ulustra- tration of which assertion we may quote his dictum on page 31, that it is " not determined whether the stars making up the galactic region are arranged in the form of a ring, with our sun and his planets in the centre," the fact being that it has been incontestably proved that by no possi- bility can such structure account for observed appearances. He is seemingly familiar with Herschel's first diagram, and knows nothing of what has been done since. Again, we should like to know when — and by whom — the supposition of the variability of Algol was found to be inconsistent with that of the revolution of a large dark planet round it, as stated on page 40. Further, he ought to be aware that the supposed determinations of the axial inclination of Yenus to the plane of her orbit are worthless; and, moreover, that a dense atmosphere would keep in the heat like a blanket and not suffer it to radiate into space as he imagines on page 74. And yet again, what in the world does he mean by Mars coming into '•partial opposition (I) . . . about every two years " ? The synodical period of that planet either is, or is not, 779'82 days. He should read up the technical meaning of opposition in any standard work on astronomy. He might as sensibly talk of partial nothingness. Into his teleological argument it is wholly needless that we should follow him ; though we may perhaps point out that on page 223, among other places, he muddles up Darwin's theo»y with Lamarck's. Has he ever opened "The Origin of Hpecies"] Students of celestial physics will be cui ious to know how and when Dr. Huggins (with Dr. W. A. ]\Iiller at his elbow) ever had to ask Dr. Frankland and IMr. Lockyer to corroborate his observations ; while astronomers will laugh outright to find the last- named gentleman's name quoted as that of an authority, in company with those of 8ir William Thomson (not Thom^json, as Mr. Parkes calls him), and Professors Young and Langley, on page 62. Aslronomicnl RevJ/ttions. (London: E. Dexter. 1887.) — • It is difiicult to enter into the feelings of a man who, knowing nothing whatever of his .subject, sets himself calmly to dogmatise upon matters of scientific fact of whose true nature and bearings he is in the most profound ignorance. and who claims to teach that of which he has not himself the most distant glimmering. Of the supernal conceit of the anonymous author of the mass of rubbish whose title heads this notice some idea may be formed from the peroration of his first chapter, in which he has bean asserting that the precession of the equinoxes is caused by the trade winds blowing the earth round Mi " And thus," he says, " more than two thousand years after the discovery of the phenomenon by Hipparchus, the true physical cause of the precession of the equinoctial points now, for the firsc time, stands revealed to the human intellect." Eeally the idea underlying this explanation (1) is delightful. The gentleman who lifted himself by the waistband of his own trowsers — to employ a current col- loquialism— " wa.sn't in it " with our author. Pending his purchase, and study, of some shilling book on mechanics, we would suggest a simple experiment to him. It is to take a pair of bellows into a sailing boat, and see how fast he can drive her along by their aid. In Chapter II. the secular acceleration of the moon's mean motion is traced to " the earth's rotatory motion round the axis of the ecliptic." In Chapter III. we learn that the diminution of the obliquity of the ecliptic will continue until it and the plane of the equator coincide I Chapter lY. shows that there is no such a thing as aberration ; in fact, that Bradley was a mere idiot. It is the deviation of the plumb-line that causes what we call aberration! ^wt finis coronal opus, and, just as schoolboys save up a piece of crackling or fat for the last, so has our author reserved his choicest revelation for his concluding chapter. The Hersehels — father and son — Miidler, Struve, Proctor, and others have fondly theorised on the constitution and structure of oar stellar surround- ings, on the assumption that the fixed stars are (practically) infinitely distant suns like our own. Not a bit of it ! " The sun, which occupies the centre of our solar system, is the only visible self-luminous body at present existing in the celestial spaces." We are surrounded by a concave sphere of land and water, from the internal surface of which this sun is reflected hundreds and thousands of times (of course only from the water). But, as in the case of the earth, what is now land may in time become water, and vice versd, so that when a fresh bit of the concave becomes watery enough to reflect our sun, a new star appears ! We feel that an apology is due to our readers for wasting even the space we have done over such utter, irredeemable trash as this ; but (always assuming that the writer of it is responsible for his actions) no denunciation can be too severe of any one of his intellectual calibre who presumes to teach that of which he knows less than nothing. His fan-ago of nonsense is beautifully printed and bound. Seven the Sacred Number. By Eichahd Samuell. (London : Kegan Paul, Trench, k Co. 1887.) — Reflecting on the shortness of human lite, there is something terribly saddening in the thought of the awful waste of time of which the author has been guilty in the compilation of the astonLshing mass of puerilities which make up the volume before us. He suflfers from what we may call septemania, in the most virulent form. Everything (he fancies) — or nearly everything — in the Bible is septenary in its arrange- ment or signification, or both ; and when it is not, Mr. Samuell insists that it ought to be, and punctuates, re- divides, alters, or otherwis3 juggles with the text in order to make it so. The amount of the most perverse ingenuity he exhibits in his exegetic ramblings is marvellous. He ha.s, moreover, the most supernal contempt for Biblical critics who differ with him, and pooh-poohs poor creatures like Westcott and Hort without mercy when their interpreta- tion of a pas.sage clashes with his own heptadic tomfoolery. Leaving, however, his work in its more purely theological 44 ♦ KNOWLEDGE ♦ [December 1, 1887. aspect to the tender mercies of competent Hebrew scholars, let us turn for a few moments to his chapter on " The Number Seven in Nature." Now, to begin with, he here alles;es that there are seven constituent colours in white light, which everyone possessing the merest smattering of science knows to be false. So, again, with our arbitrary arrangement of seven musical tones. But it is when our author arrives at our absolutely artificial systems of classifi- cation in the animal, vegetable, and mineral kingdoms that he shines the most. That they are purely conventional and in- vented to facilitate the study of the objects included in the various categories never seems to have occurred to him ; and the way in which he gets seven out of Cuvier's classification is delightful. A page or two further on he is driven to sepa- rate the aquatic mammalia (as a class) from the terrestrial ones to eke out one of his " sevens," and, later still, to adopt a kind of table from Mr. Ralph Tate to show that there were seven geological epochs I He is very great, too, in chemistry, and it will, we think, rather astonish Professors Eoscoe and Schorlemnier to see how ingeniously details in their classical book are twisted to fit Mr. Samuell's craze. We almost wonder that, in this connection, he did not give the seven bodies in alchemy. What we have said about zoological classification may be repeated, mutatis mutandis, with reference to our absolutely artificial arrangement of clouds ; while, on cognate pi-inciples, he finds seven conti- nents and seven oceans in the globe. The human body bothers him rather more, and here he flounders considerably in his efforts to show indications of some heptadic arrange- ment. Even the exploded delusion of phrenology hiis to be invoked to drag in thirty-five primitive faculties and seven rules ! Then there are seven races of men, seven sciences (Heaven save the mark !), and we sulisequently are treated to some of the arithmetical properties of the number seven. As our author obviously knows nothing whatever of the theory of numbers, he may be surprised to learn that the properties which so astonish him have their origin in our decimal system of notation, and would pertain to another number in, say, a duodecimal one. But we have already devoted very much moi'e space than it deserves to a book which would be merely ridiculous but for the pity we must perforce feel for its author. Wrapped up^ in an overwhelm- ing sense of his own almost superhuman wisdom and acumen, he is calmly thankful that to him has been revealed, in these latter days, that hidden meaning of the Bible, and, incident- ally, of creation generally, which has hitherto been concealed from the best and wisest of mankind. To any one who cares to peruse a perfect example of what we have previously spoken of as the most absolutely perverse literary ingenuity we commend the study of " Seven the Sacred Number." But he ought to be a good-tempered man, of large and charitable views, or he may finish by speaking very dis- respectfully indeed even of the author's common sense. A Treatise on Geometrical Optics. By R. S. Heath, M.A. D.Sc. (Cambridge University Press. 1887.) — Dr. Heath's volume may be described, with but scant exaggera- tion indeed, as the very model of what a work on geometrical optics should be. He has availed himself cf the researches of Abbe, Gauss, Helmholtz, Listing, and Maxwell, to say nothing of those of Cayley, Lloyd, Rayleigh, and Tait, with the result that he has succeeded in producing a text-book of great excellence. In the case of Gauss's theory of lenses. Dr. Heath works it out by elementary geometrical methods in accordance with the general plan of his work ; but subsequently supplements this by Gauss's own beautiful analysis ; which we a little fear will have to be skipped by many who will otherwise make good use of the book. The examples appended to each chapter seem remarkably well chosen. The chapters on recent improvements in the microscope, and on meteoro- logical optics, contain much that is at once novel and interesting. Philip's Flanisphere, showing the principal Fixed Stars visible for every Hoiir in the Year from Lat. 35° South. (London ; G. Philip & Son.) — This planisphere is identical in form with that of the Northern Sky, issued by the same publishers, of which we were enabled to speak so favourably on page 21 of our tenth volume, and will be found corre- sponding!)' useful by dwellers in South Australia, New Zealand, South Afiica, and part of South America. Elementary C'heuiistri/. By M. M. Pattison ^Iuir, M.A., and Charles Slater, M.A., M.B. Practical Chemistry. By M. M. Pattison Muir, M.A., and Douglas Carnegie, B.A. (London : C. J. Clay & Sons ; Cambridge : Deighton, Bell, & Co.) — Conscientiously written and brought carefully up to the present stage of our knowledge, the two volumes whose titles head this notice form an admirable and thoroughly trustworthy introduction to the study of chemistry ; and the beginner who will lead them attentively through and perform the experiments described in the second of them with his own hands will have acquired a sound knowledge of the fundamental principles of the science, and laid a solid foundation for future study. The experiments seem particularly well chosen. We have, of course, made no attempt to check the figures which abound in the book, but, opening " Practical Chemistry " almost at random at page 20G, we find the logarithm of 0'3937 given as 9 5951742; the real log. of 03937 being 9 (or, strict!)', 1) -5951654. Moffatt's Deductions from Euclid. (London : Moffatt & Paige.) — These are series of riders, corollaries, itc, to the familiar propositions of the first sis books of Euclid, some of them original and others derived from various sources. Their great use lies in the means they afford the student of finding out how far he has understood the various pro- blems and theorems which they illustrate;, and for this pur- pose they seem remarkably well adapted. An Elementary Treatise on Light and Heat. By Rev. F. WiLKiNS Aveling, M.A., B.Sc. (Loudon : Relfe Brothers.) — Elementary Chemistry. By J. C. Buckmaster. Revised and Corrected by C. A. Bickmastek, M.A., F.C.S. (London : Moffatt & Paige.) — A Pupil Teacher's Handbook of Alijebra. By Rev. A. D. Capel, M.A. (London : Joseph Hughes. 1887.) — Innumeral)le additions have been made to our textbooks of science since the craze for examination set in, and " the cry is still. They come." Many of the more recent ones have been leally too good for merely cramming purposes, and Mr. Aveling's work is among them. Both Mr. Buckmaster 's and Mr. Capel's books too at least fulfil the purpose for which they were written. A Treatise on the Ititegral Calculus. Part I. By Ralph A. Roberts, M.A. (Dublin : Hodges, Figgis, & Co. Lon- don : Longmans, Green, tt Co. 1887.) — We have a solitary fixnlt to find with Mr. Roberts's valuable addition to our mathematical text-books. It is this : that his own ac- quaintance with his subject is so intimate and profound that he occasionally loses sight of the fact that the student must, ex necessitate, approach its con.sideration from a dif- ferent standpoint, or lower level altogether, than he does. But having said this, we have little but praise for his book. His explanation of elliptic integrals is remarkably good, and throughout the work the numerous and well-chosen examples leave nothing to be desired. The Peal History of the Posicrucians. By Arthur Edward Waite. (London : George Red way. 1887.) — We would recommend Mr. Waite's very painstaking volume to all who may be desirous to get to the back of the December 1, 1887.] KNOWLEDGE 45 Eosicrucian mystery (or imposture). So much nonsense has been talked and written about this imaginary order that it is quite refreshing to find a writer competent and willing to reduce the legend to its true proportions, and show how and when it had its origin. In Mr. Waite's pages we are furnished with the means of estimating the rhapsodies of such writers as Fludd, Yaughan, and Heydon at their true value, and of realising the extent to which such deceivers were themselves deceived. "We cannot quite agree with our author that '• there is no traceable con. nection between Masonry and Rosicrucianism," because every mason will at once detect the extent to which the imaginary ceremonial of the supposititious sect was bor- rowed from masonic ritual. Mr. Waite is justifiably severe on the modern aping of the non-existent msdiceval fraternity. A Professor of Alchenuj. By Peucy Ross. (London : George Red way. 1887.) — In the volume before us, Mr. Ross has told the painful story of Denis Zachaire, an alchymist of the sixteenth century. His weary toil after the secret of the [ihilosopher's stone, and supposed success ; his marriage with a nun who had fled from the vice of a convent ; her batrayal, by one of the French nobility, to the bloodthirsty scoundrels who, under the title of the Holy Inquisition, so admirably illustrated one phase of the " infallibility " of the Romish Church ; her death by poison, and the subsequent murder of Zachaire himself by De Fonce, afford a vivid picture of those bad old times for whose return some perverted intellects yet sigh, happUy in vain. First Lessons in Science. By the Eight Rev. .J. W. CoLENSO, D.D. (Bishop of Xatal). (London : "William Ridgway. 1887.) — Here is the most delightful and instruc- tive introduction to astronomy for children that we have, so far, ever come across. It appeiirs to have been written twenty-seven years ago, but for the purpose of introducing the young to a knowledge of the system of which our own world forms a member, and of the universe of suns by which it is surrounded, it is as valuable now as on the day in which it was penned. The old solar jiarallax was, of course, employed by Dr. C'olenso, and the editor of this reissue of the bishop's work has left the resultiug figures and quan- tities intact in it. This, however, can interfere but slightly, if at all, with the educational value of the book, which we heartily commend to all who are interested in the intro- duction of science into our elementary schools. Slulies in Machine Desijn. By C. F. Archer. Series I. and 11. (London : Griffith, Farran, Okeden .fc Welsh.) — These clearly executed examples of mechanical di-awing will be found useful alike to the apprentice in the drawing-room and to the fitter at the lathe or bench. The first series con- sists of six plates of elementary examples, showing how to draw such simple pieces of mechanism as bolts and nuts, pistons, cylinder covers, P (Ih. 55m.) Notes.

(i) White here misses the win ; Kt to Q2 was the winning move, for Black could not play Q x R on account of White's reply Q X Rch, K X R, Kt to R5 ch regaining Q with a rook ahead. (j) Although from the appearance of the position it would seem at tirst glance that White could have done better, yet on closer examination it will be found that any other line of play would not have been favourable for White. If, for example, White played 27. P to Kt.5, P x KP, and White cannot play 28. P x BP on account of R to Kt7ch. (/t) P to R4 would have been stronger. (/) This move ensures the draw.

The Ereninu Star (Punedin, New Zealand), of September 7, 1887, states that there can be no doubt that Professor LoiSETTB's .System of Memory-Training is of great practical utility, and refers to information a Dunedin Student has acquired by the aid of the System in these words: — "Jlr. W. B. Eyre has demonstrated to our satisfaction that he can answer any questions correctly on the fol- lowing subjects — The Kings and Queens of England ; the Kings and Presidents of France ; the Presidents of America ; the names of Shakespeare's plays and the characters in the principal tragedies; the specific gravities of metals; the logarithms of numbers up to 100; when ancient philosophers and modern celebrities fiourished ; the dates of various inventions; the winners of the English Derby and the Melbourne, Sydney, and Dunedin Cups ; the averages made in batting and bowling by the Australian cricketers in England and the English team in Australia ; the results of the Otago and Canterbury cricket matches and the Oxford and Cambridge boat- races ; the heights of the notable mountains of the world and all New Zealand ones, as well as of monuments and spires; the average height of European soldiers ; and the length of the longest rivers in the world, &c. By the aid of the system Mr. Eyre can also repeat b.ickward as well as forward any list of figures wliich may be read to him, and he also assures us tliat be recollects poetry and prose with much greater ease than formerly. It is not improbable that he will give a public exhibition of his powers." Contents op No. 25. PiQE 1 The Stre.%m of Lite Collisions at Sea. By Gilbert R. Faith 3 Watched b.v the Dead 5 Coal. Ev W.

(Concluded from iKuje 3.) l»w;ZSjj^N the carboniferous strata, which in some places tf/^ rSw attain a thickness of nearly four miles, we tind V^si K$^ evidence of an amazing wealth of vegetation — ^1** iKia uniform in geneial character, for as yet the earth seems to have had no seasons so far as heat was concerned — but very varied in details. The most characteristic peculiarity of animal life was the prevalence of amphibia, represented chiefly by immense creatures resembling the modern salamander, but attaining a length of seven or eight feet. Enormous sharks swept through the seas of the time, armed with teeth capa- ble of crushing the strong incasing armour of the ganoid fishes which proliabiy formed their prey. As the Permian era came on, the Flora and Fauna changed by slow processes of development, both still retaining, however (over the whole earth, so far as can be judged), their tropical character. We find so marked a contrast in passing from the Permian system to the Triassic — that is, from the highest of the primary to the lowest of the secondary stiata — that had not experience taught us to recognise in such marked change merely evidence that many leaves are missing from the geo- logical record, we might be tempted to believe, willi the geologists of former times, that the primary forms of life had been for the most part replaced by new creatures. In our time, however, all we infer from the great change in many forms of animal and vegetable life is that immense periods of time passed after the last of the Permian strata were deposited before the tirst of the Triassic rocks began to be formed. The records of these vast time intervals have been destroyed by denudation. Some, however, of the old genera of plant life and of animal life still remained. Conifers, which had existed in the previous era, were now- more numerous and in greater variety. But Cycads were the predominating form of vegetable life throughout the Mesozoic per-iod, which has been called, on this aocount, the " Age of Cycads." Amphi- bians now increased in numbers, while lizards made their tirst appearance (so far, at least, as the geological record attests). Deinosaurs, which may be regarded as a connecting link between birds and reptiles, appeared and disappeared during the Mesozoic era — becoming extinct, like other transitional types, within a comparatively short time, though the absolute duration of their existence on the earth may probably be mea.sured by millions of years. The footprints of some of these creatures, which walked on their hind less, were mistaken by the earlier geologists for the traces of gigantic birds ; but although birds, and gigantic ones, ap- peared during the Mesozoic ages, the deinosaurs were not flying creatures. When we consider the enormous size of some of them, a^^ the hrontosiinr, whose feet left imprints a square yard in area ; the stegosaur, whose bony back-plates were 3 feet across; and the ailantosaur, the most massive of all known creatures, probably of all creatures which have ever existed (it seems to have been about 100 feet long and 30 feet high), we may regard the power of laying as not one which deinosaurs needed or were likely to possess. In this age, also, the great sea saurians throve, multiplied and died out. The ichthj'osaur, with eyes a foot in diame- ter; the long-necked plesiosaur, the pythonomorphic, or serpentine, saurians, of which no fewer than forty varieties have been recognised, some of them being more than 75 feet in length, were among the denizens of the sea in Mesozoic time. This was the age also of those bat-winged reptiles, the Pterosaurs, some of which were of enormous size. But these again were probably transitional forms, and are now extinct. The birds of the ISIesozoic ages, which show many reptilian characteristics, represent more successful lines of development ; and though none of the birds known to belong to Mesozoic times remained in later ages, the birds even of our own time afford in their structure abundant evidence of their descent from those earlier birds, or from their con- temporaries. It was in the long-lasting Mesozoic or secondary ages, further, that mammals, afterwards to obtain dominion over the earth, first made their appearance, though tlie traces of them are but few and far between. Teeth of a small mar. supial animal akin to the banded ant-eater of New South Wales are found as low as the Triassic strata (the lowest of the secondary formations), while in the Jurassic, or next higher system, other forms of insectivorous marsupials are found, along with one which Owen regarded as an herbivor- ous placental mammal and another which he regarded as probably carnivorous. (/Jeology has now long passed that stage of its progress when the tertiary, or Cainozoic, periods were supposed to be separated by a distinct line of demarcation from the secondary, or Mesozoic. The cretaceous system, or chalk, was found to be in many places succeeded by beds of pebljle, sand and clay, of entirely different character from any of the chalk formations. In these upper beds no fossils could be found which had been recognised in the chalk. But re- searches, at once wider and more detailed, showed that parts of the leaves which seemed thus to be missing exist else- where. The break in the continuity of deposits in some places shows only that denudation had either completely re- moved the missing strata before the higher beds began to be deposited, or else in certain regions no strata were deposited. Yet on the whole we find a marked change in the earth's aspect in Cainozoic times, as well as a characteristic difference in the manner in which the crust of the earth behaved. During the Tertiary period the continents of the earth were fashioned nearly into the forms they have in our own time. Processes of contraction affecting a crust which, owing to increased thickness and diminished plasticity, no longer yielded easily to the pressures and strains acting upon it, resulted in the formation of the great mountain ranges, by the upheaval (through side pressures) of the thick and deep strata formed during the primary and secondary periods upon the original crust. Parts of what was sea-bed at the be- ginning of Tertiary time are now found three miles above the sea level ; and doubtless other portions were raised even higher, but have been carried down fiom the positions so reached, by the action of the denuding forces which have carved the peaks and pinnacles of mountain ranges, until in many parts the inner Archaean core has been exposed. In the Tertiary strata we recognise first the signs of a diversity of temperature beginning to exist in different parts of the earth. Early in Tertiary time, indeed, even the 50 * KNOW^LEDGE ♦ [January 2, 1888. arctic regions had a mild climate, but towards the close of the long-lasting periods of the Tertiary age snow and ice had spread, not only over the whole of the arctic regions, but even over parts of the European and American continents ■which at present are free from them. This, however, must be regarded as indicating only a temporary extension of the northern snows and ice. Even during eras belonging to the close of Tertiary time the earth possessed on the whole a warmer and more equable climate in high latitudes than she has now. The vegetation of the earth now began to resemble closely the vegetation of the present day. Nearly all the genera of later Tertiary vegetation still throve on the earth. Animal life began also to resemble the animal life of to-day much more closely than duiing preceding eras. Mammals not only made their appearance on the earth, but, as usual with successful in- coming types, they showed at the outset of their career a richness and fulness of development such as they do not present in these times. The pachyderms, still the largest of the land mammals, were much larger in Tertiary times than now. In Tertiary ages, also, gigantic cetacean sea mammals, the ancestors of the whales, dolphins and kindred races of our own times, gradually took the place of the monstrous .sea saurians of preceding ages. The division of Tertiary time into Eocene, Miocene, and Pliocene periods indicates the recognition among geologists of the growth and development of modern forms of animal and vegetable life during the Cainozoic eras. For these names imply simply '• Dawn of Recent," " Fewer Ilecent," and " More Recent," '■ forms of life " being undei-stood. The lower Tertiary strata are called Eocene to show that recent forms of life begin to be recognised in those strata; in the Miocene strata recent forms of life are more numerous than they had been but still not so numerous as the ancient forms, while in Pliocene recent forms have not only in- creased in number but they now exceed the ancient forms, and in gradually increasing degree, till as we are passing from the upper Tertiai-y to the lower Quaternary or recent strata we have to change our descriptive term from Pliocene or more recent (than ancient) to Pleistocene, or mostly recent. In considering the Flora of the Eocene period, we are chiefly struck by the evidence it affords of the extension of a climate still tropical over regions now temperate, and of a climate still warm over regions now intensely cold. Plants now only found in the hotter parts of Asia, Africa, America, and Australia throve then in Canada, Scandinavia, and Siberia. Ferns and evergreens were numerous, but many deciduous trees — elms, hazels, willows, planes, chestnuts, &c., — had now made their appearance. The Fauna of this period also indicates a generally tropical climate extending over the temperate zones, and a temjjerate climate extending to far within the arctic regions. Reptilian life was no longer so preponderant as during Mesozoic time, the reptiles still thriving in the Eocene period being chiefly turtles, tortoises, and crocodiles, closely resembling those now existing. Re- mains of birds are found more freely in Eocene strata than in the lower formations, though avian fossils are naturally not abundant in any strata, the power of flight saving birds from most of those forms of death which favoured the pre- servation of fossil remains. True mammals now made their appeai'ance in great numbers. Small pony-like animals appeared — the ancestors probably of the horse, ass, zebra, and quagga, but differing from the modem equine races in possessing most of the toe of each foot, whereas the Equus of to-day possesses only the middle toe complete, the side toes being represented only by rudimentary splints. Hogs of various kinds, deer and antelopes, squirrels, lemurs and bats had now appeared. Races also now seen for the first time, but not destined to last to our own day, throve and multiplied during the Eocene period — creatures (the tino- ceras and deinoceras) like the rhinoceros in structure, but having six horns instead of two, and like the elephant in size, were now the most powerful denizens of the forest. Throughout the closing part of the Eocene period, called sometimes the " Uligocene " (or '"' Few-recent "), there was a general though slow progress towards the condition found during Miocene time, during which the Flora and Fauna showed a marked advance towards the characteristic forms of recent geological time. Still, however, even in the Mio- cene agL, the forests which adorned temperate regions resembled rather those found in India and Brazil than the forests of middle Europe and other such regions now. Beeches, laurels, oaks, and poplars, as well as magnolias, myrtles, sumachs, mimosas, and acacias, were now abundant. Through the forests ranged giraffes, deer, antelopes, three- toed horses, wildcats, bears, sabre-toothed lions, monkeys, and apes. The deinotherium and mastodon were doubtless, however, the most powerful land animals ; the deinothei'ium, as large as the elephant, with two immense tusks in the lower jaw, curved somewhat like those of the walrus ; the mastodon, a foi-m of elephant, but in some cases armed with four tusks, two in the lower as well as two large tusks in the upper jaw. The forms of insect life also were par- ticularly rich, especially the wood beetles, which attained often singularly large dimensions. Frogs, toads, lizards, and snakes were also numerous in the Miocene period. Large cetaceans traversed the Miocene seas (their ear-bones are found in considerable numbers in the raised sea-beaches belonging to this part of Tertiary time). In Pliocene times, as the name implies, modern forms of vegetable and animal life had become still more common. Tropical types of vegetation were no longer found in the higher temperate latitudes, and the forms gradually ap- proximated more and more in character to those now occupying the corresponding regions. The Fauna also pre- sented similar characteristics. Tribes of animals roamed over Europe in the earlier portions of the Pliocene period which are now found only on the southern side of the Mediterranean. In England, even in the latter part of Pliocene time, the hyena, rhinoceros, elephant, and other animals, now limited to tropical or sub-tropical regions, must have been numerous to account for the frequency of their remains. No definite dividing line can be drawn between the Tertiary and Quaternary periods. The change from Eocene to JSliocene, or from Miocene to Pliocene, corresponded closely in character with the change from Pliocene to Pleistocene. Ever since the time when life, vegetable or animal, had first appeared on the earth, multitudinous forms cf life had come into existence, had risen into greater or less prominence according to their surroundings, and had in some cases died out, in others had developed succeeding races more or less closely akin to them, and in yet others had continued scarcely changed even throughout the millions of years which separate the beginnings of the Pala'ozoic pei'iods from our own time. The steady advance of the stream of life, with its various waves thus either dying out, or merging into other waves, or progressing scarcely changed age after age, had gradually led to the development of more and more of those forms of vegetable and animal life which we regard as be- longing specially to the present age of our earth's history. For gradually the earth's surface had changed from a condition utterly unlike what now exists to nearer and nearer resemblance to its present aspect. At the be- ginning the internal heat had extended its influence over the whole surface of the earth, throughout the whole ocean. Jan-uary 2, 1838] ♦ KNOWLEDGE ♦ 51 even tbrougliout the whole atmospliere ; and the stream of life on the earth had corresponded in character to this uniformity of thermal condition. But as during millions of ages the internal heat gradually diminished, the earth began to lecognise, as it were, more dearly age after age the influ- ence of the central sun, one day to become supreme in determining the conditions of life. Throughout the later Palaeozoic, the earlier and later Me.sozoic, and even the earlier Cainozoic periods, the sun's influence was small in determining diflerences of condition between diflerent parts of the earth. But from the middle of the Tertiary era on- ward to the beginning of the era which we recognise as i-ecent — though in reality it has already lasted some l!00,000 or 300,000 years— the influence of the sun has in this sense been paramount, that it has divided the earth into climates, corresponding generally though not exactly with zones limited by various latitudes ; that is, with zones within which the sun's direct influence as mensured by his mid- d.iy height in diflerent parts of tie year has such and such definite range. What we call the Quaternary period may be regarded as beginning with the time when the sun's influence thus be- came-predominant ; when the earth's suiface became divided in respect to the forms of vegetable and animal li:e, as well as in the astronomical sense, into the tropical and sub-tropical zones, the temperate zones, and the arctic and antarctic regions. The range of the various climates which we may call ti'opical, temperate, and arctic, alteied measurably, even markedly, from time to time. Sometimes the glacial regions invaded regions which had been temperate in climate, nay, had even presented semi-tropical forms of life ; at others the ice ma.s.ses retreated even w ithin their present limits. MOON LORE AND ECLIPSE SUPERSTITIONS. By " Stella Occidens." the beginning,, according to the Elder Edda, there were two worlds — Xiflheim, or the nebulous world, and Muspelheim, or the fire-world. Muspelheim was so hot that it jurncd and blazed. The heavenly bodies were made from its sparks, and these were ])laced in the heavens by the gods, to give light to the world. The sun knew not bis proper siiberc, The stars knew not tbeir proper place. The moon knew not where her position was ;' There was nowhere grass until Bor's sons The expanse did raise, by whom the great Midgard was made. From the south the sun shone on the walls ; Then did the earth green herbs produce. The moon went aheSd, the sun followed, His right hand held the steeds of heaven. Mundilfare was the father of the sun and moon, and thej' were placed in the heavens. The sun travels at a great rate, as if some one were pursuing her for her destruction. It was supposed that a wolf, called Skol, pursued the sun, and would one day overtake and devour her. In like manner a wolf called Hate — Hrodvitneson — runs before the sun, and pursues the moon, that will one day be caught by him. These two wolves are the sons of a giantess, who dwells in a wood called Jarnved, situated east of Midgard (the earth, and the abode of a race of witches). The most formidable of all these witches is one called Maanagarm (moon-swallower). He is filled with the life-blood of men wlio draw near to their end, and he will swallow up the moon, and stain the heavens and the earth with their blood : — The moons devourer, in form most fiend- like, And tilled with the life-blood of the dead acd the dyiag. Reddens with ruddy gore the seats of the high gods. Then shall the sunshine of summer be darkened. And fickle the weather ! Conceive ye this or not ? » A Mongolian myth asserts that the gods determined to punish Arakho for his misdeeds; but he hid so well that no one could find his hiding-place. They therefore asked the sun, who gave an unsatisfactory answer; but when they asked the moon, she told where he was. So Arakho was dragged forth and chastised. In revenge he pursues the sun and moon, and, whenever he comes near enough, an eclipse occurs. To help the sun and moon in their sad plight a tremendous noise is made, till Arakho is scared away. The Aleutians and the Icelanders apparently have the idea that the moon should be treated with great respect, otherwise she would punish them by throwiug down stones. A story is told about an Icelander who stole a piece of cheese. Whilst he was eating it, he happened to notice the moon shining brightly overhead. He stuck a piece on the end of his knife and otTered it to the moon. Another time a sheep- stealer, who was feasting on a leg of mutton he had stolen, observed the moon shining bright and clear. Ho also in- vited the moon to take part in the feast in the following words : — O moon, wilt thou Od thy mouth now This dainty bit of mutton eat ? A voice from the heavens replied : — Wouldst thou, thief, like Thy cheek to strike This fair key, scorching red with beat ? A red-hot key fell from the sk}^ burning on the thief's cheek a mark which remained for ever afterwards. This was supposed to have originated the custom of branding thieves, though why a key should have been chosen in this case it is difficult to imagiue.t In Scotland, Devonshire, and Cornwall, pointing at the moon is an insult to \>e care- fully avoided, or the most dire results may follow. At Whitby when the moon is surrounded by a halo of watery clouds, the seamen say that there will be a change of weather, for the moon-dogs are about. An amusing story is told about a fisherman in Torquay. A gale having taken place during the night, he said he had foreseen it, as he had noticed a star ahead of the moon towing her, and another astern chasing her — " I know'd 'twas coming safe enough." In the Yedic hymns Rakha, the full moon, is supposed to make beautiful garments for night and morning, with a needle which can never be broken. She weaves together the roseate hues of morning, and the soft mellow tints of evening. The Danes have elves called " Moon Folk." The man of this race is like an old man with a low- crowned hat upon his head ; the woman is very beautiful in front but behind she is hollow, like a dough-trough, and she has a sort of harp on which she plays and lures young men with it, and then kills them. The man is also an evil being, for if any one comes near him he opens his mouth and breathes upon the rash moital, and his breath causes sickness. It is easy to see what this tradition means ; it is the damp marsh wind laden with foul and dangerous odours ; and the woman's harp is the wind playing across the marsh- * "Xorse Mythology," Anderson, pp. 17C-1T9. ■f Harley, " Moon Lore," p. 150. 52 ♦ KNOWLEDGK ♦ [Jakuaey 2, 1888. rushes at nightfall.* In the " Midsummer Night's Dream " the fairy queen says to the king : — These are the forgeries ot jealousj' ; And never, since the middie summer's spring, Met we on hill, in dale, forest, or mead, By paved fountain, or by rushy brook, Or in the beached margent of the sea, To dance our ringlets to the whistling wind ; But with thy brawls thou hast disturbed our sport. No night is now with hymn or carol blest : Therefore the moon, the governess of floods, Pale in her anger, washes all the air. That rheumatic diseases do abound ; And this same progeny ot evil come.s From our debate, from our dissension ; We are their parents and oiiginal. Among the Mexicans an eclipse of the moon is supposed to be the moon devoured by a dragon. The Hindoos have the same belief, and both nations continued to use the expression long after they had discovered the true cause of an eclipse. t Captain Beechman relates that one evening when he was at supper with .some friends in the island of Borneo, thev heard a great noise outside. " The natives were yellinar, and clattering brass pans and gongs, and firing off guns. When we inquired the reason of their excitement, one of the natives pointed up to the heavens, and said, ' Look there; see, the devil is eating up the moon 1 ' " Among the Chinese the belief exists that the moon during an eclipse is being devoured by a hungry monster. In order to frighten him away, and to save the moon from total destruction, certain ceremonies are performed by the Chinese mandarins, which form, in fact, part of their official business. An instrument made of bamboo splints is beaten, which makes a great noise, supjMsed to penetrate the very temple of Heaven itself. Tapers are lighted at the begin- ning of an eclipse, incense is burned, the mandarins prostrate themselves on the ground, and the priests recite formulas, all this Listing until the eclipse has passed off. We are naively told that they are invariably successful in driving away the hungry monster.J At one time in Canton the sky happened to be cloudy during an eclipse, and we are told that the courtiers con- gratulated the emperor that lie had been spared the pain of seeing the sun devourerl. Among some of the American Indian tribes a belief exists that the moon is hunted by huge dogs, catching and tearing her till her soft light is reddened and put out by the blood flowing from her wounds. " At a lunar eclipse the Orinoco Indians would work hard, as they imagined the moon was veiling herself in anger at their habitual lazine.ss." § It was customary among the Romans to take their brazen pots and jsans and beat them together, making a most unearthly noise, duriug an eclipse. They also lit torches and firebrands, and carried them abotit with them, hoping by these means to release the moon. The Mexicans would make a great noise during the eclipse with musical instruments, and would make their dogs howl, hoping the moon would have pity on them because of their cries. The Creeks did likewise, and they explained this strange custom by saying that the big dog was swallowing the sun, and they could prevent him from doing so by whipping the little one.?.

They would offer presents to the god whom they supposed to be swallowing the moon.* 'The Sinalos fancied that a battle was taking place in the moon, of great consequence to those on earth. The people would encourage the moon by shouting and yelling, and would shoot flights of arrows at her, so as to distract the enemy.t In eclipses of the moon the Greenlanders carry boxes and kettles to the roofs of their houses, and beat on them as hard as they can. The Lithuanians think a demon is attacking the chariot of the sun ; darkness comes, and though the sun will be saved many times, yet it must be destroyed at the end of the world. Among the Moors the people ru'i about as if mad during an eclipse, firing their rifles, so as to frighten the monster, who, they suppose, wishes to devour the orb of day. The women bang copper vessels together, making a noise to be heard at a very great distance.t TRICKS OF MEMORY. EMOPiY, which differs so gi-eatly among in- dividual men, varies also in such marked degree in the same person at different times that we are all intei'ested in the inquiry how far memory is a measure of mental strength. In childhood and boyhood we find memory occupying .so high a position among mental qualities, that the idea grows up with most of us that he who has the best memory has also most talent, if even a remarkable memory be not regarded as of itself proving absolute genius. At least this is so inmost of our schools, where the boy who remembers his lessons best takes highest position, not he who best understands them. I learned very early that memory and mental power, though they may be associated together, are yet very different things. I valued my memory, which had often stood me in good stead in examinations, the only tests with which boyhood is apt to be acquainted ; but I valued more the power of understanding and enjoying the reasoning of dear old Euclid, the one geometrician with whom, in those days, English school lads could become acquainted. Soon after I had left school — and when I was a freshman at college — I made the acquaintance of a young man of about my own age who possessed a most marvellous memory, while he also showed most marvellous mental density. He had occasion to pass examinations in Euclid, and one would have said that he would have been singularly successful in these examinations, for though he had only read through our college Euclid once, he could recite or write out the whole of it. Or, if preferred, he could begin at any point where one might start him and reproduce any quantity verbatim et literatim — atq^ie punctuatim, so far as that was concerned. But not only was he utterly unable to under- stand a word of it all — he had not even brains enough to keep his real ignorance of Euclid to himself. He was always forgetting the good old rule ne quid nimis ; and as he did not know where to stop in his marvellous recita- tions, the examiners naturally came to the conclusion, per- fectly justified by the facts, that though be knew his Euclid by heart he knew nothing about geometry. His knowledge was akin to that of one who should repeat by rote a number of Greek or Hebrew words the meaning of which was unknown to him ; or like that of a tutor I once had, * Harley, "Moon Lore," p. 173. t Grim'in's " Teutonic Mythology," p. t Ibid. p. 173. 707. J-^N-i-AEY 2, 1888.] ♦ KNOWLEDGE ♦ 53 ■who when hearing me deal with a problem in Euclid would send me back to relearn my lesson if I called a triangle A C B instead of A B C as the book showed it. ^ye need not then either despair of our mental powers when we hear of marvellous feats of memory, or think that our minds are failing because with advancing years our memory may occasionally play us false. Memory, as Dr. Diordat, of Montpelier, long since pointed out, and as hun- dreds of facts show, is rather the offspring of the vital force than of the intellectual principle ; and it is not surprising if in old age, when the vital force diminishes, memory should sometimes fail, even while the intellectual power preserves its full integrity. As for marvellous feats of memory, though they certainly indicate possibilities of future develop- ments which would greatly increase man's grasp over mental problems, they need no more dL^courage those who feel incapable of any achievements in this line than the mental powers of Blind Tom should cause those who see his performances to despair because they can never hope to do the like. The examples themselves which most strikingly display the capacity of special brains for remembering words and syllables show also how little this capacity has to do with intellectual power— some of them indeed seem almost to suggest that a very keen memory may be a mark of disease. That excessive keenness of memory may result from a diseased cerebral action is indeed certain ; but fortunately we are not obliged to regard this fact as giving any unplea"- sant significance to exceptionally good powers of remem- brance. If foolish, or even idiotic persons, or persons in the delirium of fever, have manifested remarkable memories, men like :Macaulay, Prescott, Euler, and others have had marvellous memoiies without being feeble-minded and without the aid of disease. Pepys tells us of an Indian who could repeat a long passage in Greek or Hebrew after it had been recited to him only once, though he was ignorant of either language. This man would doubtless have been able to repeat (so far as his vocal organs would permit him to imitate the sounds) the song of a nightingale or a lark, through all its ever- varying passages, during ten or twenty minutes, and with as much understanding of its significance as of the meaning of the Greek and Latin words he recited so glilily. We cei° tainly need not envy that particular " poor Indian " his "untutored mind," though as certainly the power he possessed would be of immense value to a philosopher. If any one is disposed to believe that perhaps after all that Indian may have been a man of powerful understand- ing, a case of even more wonderful recollection of mere sounds will at least dispose of the idea that the man's pecu- liarly retentive memory proved mental power. Coleridge relates, in his '' Literaria Biogniphia," that in a Roman Catholic town in Germany a young woman who could neither read nor write was seized with a fever, during which, according to the 'priests, she was posses^sed by a polyglot devil. For she talked Latin, Greek, and Hebrew, besides uttering sounds which, though not understood by her hearers, had doubtless meaning, but belonged to languages unknown to them. " Whole sheets of her ravings were written out," says Coleridge, " and were found to con.sist of sentences intelligible in themselves, but having slight con- nection with each other." It appeared rather" inconsistent with the theory of demoniac possession that .some of these sentences were Biblical ; but as it is proverbial that the devil can quote Scripture for his purpose, this evidence might not have availed to save the girl from such rough treatment for her -'possession" as would probably have served very ill for her fever. Fortunatelj", a physician, who, being sceptically inclined, was disposed to question the theory of a polyglot spirit, " determined to trace back the girl's history. After much trouble he discovered that at the age of nine she had been charitably taken bv an old Protestant pastor, a great Hebrew scholar, in whose house she lived till his death. On further inquiry it appeared to be the old man's custom for years to walk up and down a passage of his house into which the kitchen opened, and to read to himself in a loud voice out of his books. The books were ransacked, and among them were found several of the Greek and Latin fathers, together with a collection of Rabbinical writings. In these works so many of the pa.s- sages taken down at the young woman's bedside were identified, that there could be no reasonable doubt as to their source." If the girl had remembeied these passages in a normal way, and had merely uttered them during her sickness, the story would have been remarkable enough, since she was altogether uneducated. But, as a matter of fact, she re- membered none of thorn in health, either before or after her sickness. It was doubtless the activity of the circulation during the access of fever which brought out as it were the impressions of sounds really recorded in the brain, but so lightly that except during such situation she remained unconscious even of their existence. A case cited by Dr. Abercrombie confirms the suggestive theory that the stimulus which fever gives to the circulation (sign of disease though it is) may bring dormant mental im- pressions into temporary activity. A boy at the age of four had undergone the operation of the trepan, being at the time in a stupor from a severe fracture of the skull. After his recovery he retained no recollection eil;her of the accident or of the operation. But at the age of fifteen, during an attack of fever, he gave his mother an account of the operation, describing the persons who were present, and even remembering details of their dress and other minule particulars. Even an accident may stimulate the memory in such sort as to recall long-forgotten neutral impressions, and so to convey that the mind is regularly retentive. Dr. Aber- crombie relates a case of this kind which suggests many perplexing problems in regard to memory. A ruan who had been completely stunned by a blow on the head remained still partially out of bis mind when he had recovered from the first effects of the blow. In his unconscious ^tate he spoke a language which nobody in the London hospital to which he bad been removed could understand, but which was presently found to be Welsh. It was subsequently dis- covered that, though Welsh liy birth, he had been thirty years away from Wales when the accident occui'red, and had quite forgotten his native tongue. On his restoration to full consciousness he lost his Welsh again completely, but recovered his English. The effects of an accident — in destroying temporarily, or, .so far as it appears, wholly — all neutral impressions received within certain intervals, are sometimes curious enough. Thus Dr. Carpenter mentions the case of a friend of his— a clergj'man — who was pitched out of a phaeton, and received a severe concussion of the brain. On recovering he found that he had forgotten all that had happened, not only when the accident actually took place, but during some previous time. The last thing he remembered was that he had met an acquaintance on the road just about two miles from the accident. An access of fever may produce, as we have seen, a local disturbance of brain functions. It is further worthy of notice also that the recollection a man has of events preced- ing intoxication is apt to be similarly limited in a definite but not readily explicable manner. I remember a Cambridge man who, though not given to 54 ♦ KNOW^LEDGE [January 2, 1888. di-inking, and now " a sober man among Lis sons," was more than once overtaken by liquor during the time when he bad yet to learn his brain's exceptionally limited power of resisting the action of intoxicants. This man would not only be unable to recall what had happened during the time when he was intoxicated, but a number of preceding events which had taken place while be was still perfectly sober. His friends would tell him of things which had happened a full hour before he was " overtaken" (as the quaint expression has it), which had altogether passed from his remembrance. He used to say that his recollection was clear up to a certain point, bej-ond which everything seemed " veiled." But it was clearly shown by an experiment which he arranged for his own satisfaction — being one of the inquisi- tive sort — that the veiling was, as it were, extended back- wards from the time of actual intoxication, for whereas his forgetfulness extended over the whole interval from the fir.>t glass of wine (which he always remembered drinking) to the sixth or seventh at which intoxication began, he couLl remember with accustomary readiness all that happened at a sitting where he had drunk four or five glasses of the same wine. Of course he had to trust to his friends to note for him at what stage intoxication began ; in fact, until he had learned this from others he could know little about it, because of the peculiar veiling of past events which took place after he had passed that stage. But his friends not being of the sort who rejoice to see a man under the influence of liquor, he had confidence in them; and beiides, he could prove so much as tliis for himself, that whereas he could never remember more than the first glass if he drank tco much, he could drink four or five glasses safely, remem- bering all that happened. What he could not learn for himself was, how many more glasses he could take without intoxication. At last he could only obtain this knowledge in such sort that he was conscious of it while intoxicated ; for his friends found that after the sixth or seventh glass, which produced intoxication, he could always remember every detail of what had happened during previous acces- sions of the temporary insanity we call drunkenness. The way in which this man's mind came out from the " veiling" was as strange and as suggestive as the way in which it was thrown under that veiling. I remember being present at the moment when consciousness or sanity (whicdi- ever we choose to call it) came back to him. He was a mathematician, and a man had put in his hand to test his condition a mathematical treatise on mechanics, over which my friend had maundered, as drunken men will. Suddenly his mind seemed to straighten up, and, in response to a remark that he was " screwed," he turned to the pages in the book dealing with the screw, and said quaintly, " See liere, A. You 're a classical man, and know nothing about mathematics ; but these angles, Alpha and Beta " (showing a diagram^ " represent the pitch of these screws. Now you needn't pitch into me about being screwed, for if I 'm screwed at an angle Alpha, you're screwed at an angle Beta." (A. really was at the time the worse for liquor, l)ut the other who had been so a moment before, was, from the moment lie had opened t!ie bock, perfectly clear-minded, and a few minutes later was at his mathematical studies.) Mr. NOKDEXSKIOLD some time ago received an account from Don Carlos Stolp, of San Fernando, Chili, of his observations of the "red sunsets" of 1883-1884, from a point on the ,\ndes about 15,000 feet above the sea, and afterward Senor Stolp sent some specimens of an atmospheric dust which he had observed at the same time. Analysis of this dust .showed that it had no relation to volcanic dust, but that it was of the liind regarded as cosmic dust — containing the iron, nickel, phosphoric acid, and magnesia constituents characteristic of tlie cosmic deposits. There is, however, no evidence that this dust was connected with the red IJglit. EDISON'S PHONOGRAPH. y answer to questions about his phonograph, Mr. Edison said recently : — " Perhaps I am wrong in telling you any- thing about my phonograph, becattse what I claim for it is so extraordinary that I get only ridicule in return. I am so confident that when the apparatus appears it will dispel all doubts as to its practicability and working value, that I can afford for the present to ignore all kinds of criticism, and keep at my work regardless of the storm which I have been raising by telling a few people that there was such a thing as a perfected phonograph in existence. I am sure that while scientific men may doubt that I have succeeded as well as I say I have, they will admit that there is nothing at all impossible in what I claim, and that the germ of the perfected phonograph, shoidd such a thing appear, is very clear in my old toy of ten years ago, which was exhibited all over the country, and was then acknowledged to be one of the wonders of the century. Just consider for a second what my old phonograph is, and think how little needed to be done to bring it to a working instrument. With my roughly-constructed instrument of 1877 I reproduced all sorts of sounds, getting back from the phonograph some- thing like the original sound. Of course you had to yell into the thing ; and the reproduction of conversation was often something of a caricature of the original. Neverthe- less, to obtain a result that could be understood was doing wonders ; and most people who remember my exhibitions will admit that, while I did not produce a commercial machine, I made a very interesting and creditable attempt, and my whistling and singing phonograph was a wonder. "There were all sorts of objections in detail to my first instrument. It weighed about one hundred pounds ; it cost a mint of money to make ; no one but an expert could get anything intelligible back from it ; the record made by the little steel point upon a sheet of tin-foil lasted onlj' a few times after it had been put through the phonograph. I myself doubted whether I should ever see a perfect phono- graph, ready to lecord any kind of ordinary speecii and to give it out again intelligibh'. But I was perfectly sure that if we did not accomplish this, the next generation would. And I dropped the phonograph and went to work upon the electric light, certain that I had sown seed which would come to something. For ten years the phonograph has come up in my brain automatically and almost periodi- cally. I would turn it over and over mentally when I had nothing else to think about. W^hen I couldn't sleep at night, when travelling, when worried about business affairs, I would think the phonograph over and jot down any new ideas for future experiments. Eight months ago I began laboratory work upon it again, and a month ago I stopped because I could see no further improvement to be made. It is a finished machine — simple, cheap, effective, not liable to get out of order, and it does everything that I ever hoped the perfected phonograph might do. " My phonograph will occupy about as much space on the merchant's desk, or at the side of the desk, as a typewriter does. It will work automatically by a small electric motor, whicli runs at a perfectly regular rate of speed, is noiseless, and starts or sto[)S at the touch of a spring. Suppose the merchant wishes to write a letter, he pulls the mouthpiece of the phonograph to him, starts the motor with a touch, and says what he has to say in an ordinary tone of voice. When he has done he pulls out a little sheet and rolls it up for the mail. The recipient places this sheet in a similar phonograph, touches the motor spring, and the instrument will at once read out the letter in a tone more distinct January 2, 188S.] KNOWLEDGE ♦ 55 clearer, more characteristic of the voice of the writer than any telephone you or I ever heard. The phonograph voice is not a loud voice, perhaps not more than twice as loud as the sound you get from a good telephone, and an earphone will be necessary. This, however, may not be an objection, inasmuch as people do not always want to have their letters heard all over the otEce. In aiming for loudness in the phonograph, I went astray in my first experiment ; I should have tried for clearness. The present apparatus will satisfy any one who is half satisfied with the telephone. Of course, there are no disturbances in the phonographic message such as those made by induction along a telephone wire, and, as the apparatus will repeat the letter over and over again, it is possible to understand every .syllable, even in a noisy oiEce. I was so overcome with the .'uccess of my first instrument, finished about six weeks ago, that I doubted whether I could make another equallv good, and I went to work at once to do so. My second instrument works as well as the first, and I have forty woikmen employed in making the tools for the manufacture of the first lot of 500 phonographs. They will cost GO dols. apiece. " Now for some speculation as to what people mav do with the phonograph. I am confident that it will be found in the ofiice of every busy man. I am confident that the editor and the reporter of the future will never think of losing time by writing with a pen or dictating to a stenographer when the printer can set type better from the dictation of the phonograph than he can from copv. I have already perfected an apparatus whicli allows the phono- graphic message to be given out in pieces of ten words eacli. The printer touches a pedal with his foot and the phonogi'aph says ten words. If he sets the ten correctly, he touches the pedal again and gets ten words more. If he is in doubt he tries another pedal, which makes the phono- graph repeat. In the future some method may be found of combining the phonograph and the telephone — that is to say, the phonograph may be made so delicate as to take down the sound from a telephone and give it out again when wanted. As yet I have not attempted any such thing. The vibrations of the telephone diaphragm are too delicate for use in the phonogiaph. In business I think that the phonograph will be used everywhere. Outside of business it is hard to say exactly to what uses it may be put. As it will record and repeat any kind of musical sound, and as the process of duplicating the phonogram, as I call my sheet of metal which has passed through the phonograph and become impressed with certain sounds, is very cheap, the phonogram copy of a lecture, a book, a play or an opera need cost but a tritle. " For music, I know that you will simply laugh when I tell you wliat I have done with the two instruments that I have finished. I have got the playing of an orchestra so perfectly that each instrument can be heard distinct from the rest ; you can even tell the diflerence between two pianos of different makes ; you can tell the voice of one singer from another ; you can get a reproduction of an operatic scene in which the orchestra, the choruses, and the .soloi-sts will be as distinct and as satisfactory as opera in this sort of miniature can ever be made. Opera by telephone has been done in Paris and London more or less .successfully, but the phonograph will eclip.se the telephone for this purpose bej'ond all comparison, and phonographic opera will cost nothing, because the phonogram can be passed through the phonograph, if necessary, a thousand times in succession, and once the machine is bought there is no other cost beyond tbe trifle for phonograms. For books, the phonogram will come in the shape of a long roll w-ound upon a roller. To make the first phonographic copy of a book, some good reader must of course read it out to the instrument ; once that is done, duplication to any number of thousand or million copies is a simple mechanical work, easy and cheap. Now, just think a moment what that means. " Suppose you are sick, or blind, or poor, or cannot sleep. You have a phonograph, and the whole world of literature and music is open to you. The perfected phonograph is going to do more for the poor man than the printing-press. No matter where he is. the poor man can hear all the great lectures of the world, can have all the great books read to him by trained readers, can hear as much of a play or an opera as if he was in the next room to the theatre, and all this at a cost scarcely worth mentioning. I remember that when the telephone was first announced it was said that now people in the wilds of Africa or America might assist nightly at the performances of the Paris Opera House ; the wires from that favoured spot might run to all parts of the world. Well, we have not yet got to that, although it is a scientific possibility for the future to perfect in detail. But the phonograph will make such a thing perfectly easy. The phonographic record of a performance of the Paris Opera House can be duplicated by the thousand and mailed to all parts of the world. I don't know but that the newspaper of the future will be in the shape of a phonogram, and the critic will give his readers specimens of the performance and let them hear just how the future Patti did her work, well or otherwise. This sounds like the wildest absurdity, and yet, when you come to think of it, why not 1 Have I told you enough to make you believe that I am joking? Well, I am nothing of a joker, and this is all the most sober kind of statement. Within two months from now the first phonographs will be in the market." COLLISIONS AT SEA. By W. B. RoBiNsox, Chief Constructor, E.N. (Retired). HE interest and importance of the following communication will be recognised by all readers. " Gossip " is omitted this month to make room for this letter, which reached me at my Florida home rather late. — E. P. "Eeferring to Mr. Gilbert R. Faith's paper on ' Collisions at Sea ' in your November number of Knowledge, let me say that the article in question has been written under an entire mistake regarding what happens when the rudder of a ship is put over. The effect of putting the helm over when the ship is under way is to tend to make her turn, as she proceeds, nearly around her centre of gravity, and to finally revolve in almost a circle, her speed being lessened till it reaches, with the same horse-power, nearly a fixed quantity. The trials of all the ships of the Eoyal Navy prove this to be the ca.se ; hence Mr. Faith's supposition that a ship, so to say, pivots on her bow, is an error. I semi herewith a photograph of the port bow of the Konig Wilhdin, which collided with and sunk the Grosser KurfUrst, from which picture it will be seen that the former ship must have struck the latter at an oblique angle with her starboard bow. The photo was taken when the ship was in dock at Portsmouth before the injured bow was touched for fitting a temporary one designed by me. The supposition that ships when turned by their helms pivot on their bows being a mistake, all Mr. Faith's deductions therefrom become erroneous. — W. B. Eobinson, Chief Constructor, E.N. (Eetired)." [The subject with which Mr. Faith and Mr. Eobinson have dealt is so important that it deserves to be very thoroughlv ventilated. Mr. EobiuEon's statements com- 56 ^ KNOW^LEDGE ♦ [January 2, 1888. maud acceptance, being based on experiments of a decisive character. Tliey also correspond with theoretical con- siderations, and I expected, indeed, when I inserted Mr. Faith's interesting and suggestive paper, to find his state- ments corrected to some such degree. For it was manifest to me, viewing the matter merely as a problem in hydro- dynamics, that putting a ship's rudder over to either side must tend to cause (apart from loss of way) rotation around a vertical axis passing nearly through the centre of gravity. But I cannot agree with Mr. Robinson that Mr. Faith's deductions become erroneous. On the contrary, Mr. Robinson has proved for us that Mr. Faith's main deduc- tion is sound. If two ships are proceeding on such a course as would bring one slantingly into the side of the other, and they are already close, following the sailing instructions will only make the collision more destructive, unless when the rudder is put over by the latter she pivots round her stern — • which does not happen. Running directly counter to the printed instructions, would, on the contrary, give her a good chance of escape. — Ed.] MATERIAL OF THE UNIVERSE. HAVE just completed a chapter of a book on astronomy, in which I have had to consider the measuring and weighing of the solar .system, and I must confess that although I have long been acquainted with the v.arious facts in detail which I have found occasion to discuss in the chapter, I have risen from the study of those facts as thus collected with such feelings of awe at the marvels of our universe, .and wonder at man's resolution in mastering tlie secrets of Nature as I have never before experienced — at least in like degree. I propose now to run through some of the results belong- ing to tliis chapter in the history of astronomy, and then to .show .something of their bearing on our estimate of the universe, regarded alike with reference to its extension in space and to its duration in time. Our earth's weight, not estimated by the comparatively rough methods of compaiison in which a mountain serves as the counter weight, or the approach towards the e.arth's centre permitted in a mine is trusted in to indicate the earth's density, but definitely weighed against known oiasses of matter, amounts to about .590,0.54,000,000,000,000,000 tons — a mass easily expres.sed in numbers, l)ut utterly incon- ceivable by the human mind. The moon, at a distance of 238,830 miles, has a mass equal to about one eighty-first part of the earth's ; but even her smaller mass is as hopelessly beyond our powers of conception as that of the great globe on which we live. I am not sure but that, looking on the moon as she rides high above tlie horizon and noting how small she looks, queen though she be of the orbs of night, there is not somet hing more i mpressi ve in the thought that that calmly beautiful globs contains 7,300,000,000,000,000,000 tons of such matter as makes the mass of our earth, than even in the consideration that our earth weighs nearly eighty-one times as much. The earth had always seemed the very emblem of stability and massive might, insomuch that though man in his days of ignorance imagined compara- tively narrow limits to his terrestrial domain, there were hardly any limits to the mass or quantity of matter he might attribute to her. But the full size of the moon is visible to every human eye ; and the contrast between the apparent and the real is much greater when, for example, we consider that that silvery surface at which we look yonder is 2,160 miles in diameter and contains 7,300,000 square miles of just such rock surface as we have on our earth, than when, looking out upon our earth as far as the eye can reach, we learn that the real extent of the earth is many thousandfold greater than the area thus .^.urveyed. And if this is so in striking degree in regard to the moon's apparent size, it is still so in more impressive manner when we consider her mass. Passing beyond the moon to the region of space outside, we may turn at once to the sun. Within his fiery globe lies very nearly the whole mass of the solar system. He looks no larger than the moon, but he is 60,000,000 of times larger, and more than 26,750,000 of times as massive. His mass surpasses our earth's 330,500 times, a disproportion of wdiose full meaning we can only form a fair idea by con- sidering separately first the inconceivably large mass of the earth, and then the enormous number represented by the figures 330,500. On this last point I may remark that few (so far as my observation has gone) form definite concep- tions of the meaning of large numbers, even when such meaning is well within their power of appreciation. To most men 300,000 is a number whicli, even when it represents money, is not definitely difl'erentiated in the mind from such numbers as 200,000 or 400,000, or even from such numbers as 30,000 or 3,000,000. Yet there are simple ways of obtaining a clear idea of what it represents. Draw a straight line 10 inches long, and, completing a square on it, divide up this square into 100 small squares by lines 1 inch apart drawn parallel to the sides. Take a corner square, and, dividing its .sides into tenths of an inch, divide it like the large one into 100 small .squares. Then the meaning of the number 10,000 is very clearly shown so soon as we notice that our 10-inch square contains 10,000 such .squares as make up the 1-inch corner square. The eye sees in this case the degree in which 10,000 surpasses 1 ; and we all know the truth of old Horace's saying, Segnius irritant animos demissa per aures, quam qiur sunt oculis suhjecta fidelihus. It is now ea.sy, without further drawing, to imagine ten such squai'cs as our large one, and thus to recognise the significance of the number 100,000. Thirty such squares would picture the meaning of 300,000, the small tenth-of- an-inch square in the corner being the unit. And thus we can readily form a good mental conception of the degree in which the sun's mighty mass surpasses the earth's — though we still remain, and must for ever remain, unable to appre- ciate the stupendous significance of the six hundred millions of millions of millions* or so of tons contained within the bulk of our terrestrial home. * According to our English system we call this six hundred trillions. In America the expression would be quintillions. I object altogether to use an expression which has no true significance. It includes the number .5 (quint) ; but no 5 is logically includible in it. A quintillion, according to the English system of numeration, signifies a million raised to the fifth power; according to the American (want of) sjstem, it signifies a million multiplied by a thousand raised to the fourth power. One c.in get a 5 in, indeed, thus : A quintillion is a thousand multiplied by a thousand raised to the fifth power; but that is an obviously unsymmetrioal way of representing a thousand raised to the sixth power. If the American system were sound logically and mathematiciilly, it would not be so convenient as the English system, for when we get into such numbers .as trillions, qu.adrillions, and so forth, which only happens when we are comparing numbers all of whicli are very large, it is desirable not to contuse comjiarison by having too many different names, or (which is the same thing) by separating our classes of numbers by divisions too closely set. Lastly, in giving names to large numbers the English .system is superior to the American, though there is no difference in the numbers of words employed. The first example, taken at random, will serve to show this to the logical arithmetician. Letthe number be 321, 563,482,793,81 2,4,')6,259: for this the American name would be three hundred and twenty- four quintillions, five hundred and sixty-five quadrillions, four hundred and eighty- two trillions, seven hundred and ninety-three January 2, 1888.1 ♦ KNOWLEDGE ♦ One of the most impressive thoughts respecting the sun's mass is the might which it represents — might ahsolutely essential to his rule over the solar system. To give b^- a simple example an idea of the sun's tremendous power, imagine an immensely powerful magnet acting at a distance of one mile on a particle of uon. and trj' to conceive the slow motion by which at first that particle would respond to the magnetic attraction. Now suppose this magnet ! replaced by a body having the sun's attractive might, but all collected in a one-inch globe ; and suppose, further, that this concentrated sun acts on a body from the distance of a mile all the time (a whole second is all the time I ask for), retreating from the body as, under its attractive influence, the body moves towards it, and so always maintaining that distance of one mile unchanged. Then, in that second, the attraction on the body would be so great as to communicate a velocity of 31,000 millions of miles per second. Or, in a period of time so inconceivably short as one millionth part of a second, our sun's mass, concenti-ated into a one-inch globe, would at a mile distance (kept unchanged) communi- cate the tremendous velocity of 31,600 miles per second. Our sun surpasses in mass all the members of his family together more than 74.5 times, so that there is no question of his absolute supremacy over that family. Yet 8ii- John Herschel fell into a mistake when he asserted that, if all the planets were in a row on the same side of the sun, each at its proper mean distance from the sun, the centre of gravity of the whole system would lie far within the globe of the sun. The centre of gravity would be 937,000 miles from the sun's centre. This does not prevent the sun from exerting supreme sway over the planets, however. Indeed, the fixed centre round which the sun and all the planets travel — this centre being the centre of gravity of the solar j system at the moment — is nearly always within a much smaller distance from the sun's centre than I have just named, since it vei-y seldom happens that even three of the chief planets of the system conjoin theii- influence on the same side of the sun. The sun's motion around the common centre may be regarded as made up of motions in a nearly circular ellipse at a mean distance of 460,000 miles due to Jupiter's attraction, in another at a mean distance of 253,000 due to Saturn's attraction, and in two others at mean distances of 79,000 and 145,000 miles respectively, due to the attractions of Uranus and Neptune, all other attrac- tions being relatively inappreciable. And jast here I cannot but touch, in the way of correc- biUions, eight hundred and twelve millions, foar hundred and fifty- six thousand, two hundred and fifty-nine ; the English name for the same number is three hundred and twenty-four trillions, five hundred and sixty-five thousand four hundred and eighty-two billions, seven hundred and ninety-three thousand eight hundred and twelve millions, four hundred and fifty-six thousand two hundred and fifty-nine. Each name contains forty words, but the English, with its hundreds of thousands of trillions, billions, millions, and upits, is much more systematic, and conveys a much clearer idea than the American with its hundreds of quintillions, quadrillions, trillions, billions, millions, thousands (observe the entire change in the character of the nomenclature here), and units. I think it hardly necessary for me, after now some fourteen years, during which 1 have shown the utmost readiness to appreciate things American at iheir full value— a readiness which many among my fellow countrymen regard as extreme and unpatriotic (though that is nonsense) — to explain that it is from no desire to find fault that I thus dwell upon the unscientific and illogical nature of the system of numeration adopted in American schools. The system, employed as it now is, throughout the whole of the great American section of the English-speaking race, involves serious inconvenience from the mere fact that it differs from that employed elsewhere where English is spoken and written. Probably when it was intro- duced American arithmeticians hardly looked forward to the time when America would take so large a share of the scientific work of the English-speaking races as she does at present. tion, on the strange mistake made by my friend Mr. Mattieu Williams in imagining that the motion of our sun in the path thus determined, about the common centre of gravity of the solar system, can in any appreciable degree affect the condition of the sun's interior. He has presented in his suggestive book, " The Fuel of the Sun " — a book full of novel ideas, but not free from startling mistakes — the quaint notion that as our sun goes circling round and about the common centre of gra\ity of the solar sy.st€m, his material is swayed about with all sorts of effects and influences, stirring it up, intermingling it, keeping it active, and so forth, as might happen, for example, if the glowing fuel within some great furnace were constantlv stirred up by the swaying round of the whole furnace by some powerful mechanism. The mistake is, perhaps, a not tmnatural one. Something akin to it was made even by so skilful a mathe- matician as Professor .Simon Newcomb, when, in the first edition of his " Popular Astronomy," he presented the tides as a product of centrifugal tendencies called into action as our earth circles around the common centre of gravity of the earth and moon.* Mr. Williams's idea about a stirring up and shaking together of the solar fuel is entirely erroneous. If the sun were swinging bodily round a fixed axis, in such sort that while some parts of his mass (being near to that axis) moved much, there would result a certain stirring up of the solar material which might, for anything I know to the con- trary (though I have given no attention to so purely hypo- thetical a case), have some such effects as Mr. WiUiams imagines. But there is no such swinging. The sun moves as a whole (with inconceivably slow motion, too), around or upon his somewhat complex orbit, each particle moving in an orbit of exactly the same size, so that there is no relative motion among the different parts of his mass, and therefore no strains or pressures are produced and no interchanges of position occur. I imagine that few recognise fully the next most striking feature of the solar system after the amazing superiority of the sun's mass — I mean the startling discrepiucy between the outer family of planets and the inner. Each contains four primary bodies — .Jupiter, Saturn, Uranus, and Neptune forming one. Mercury, Yenus, the Earth, and Mars forming the other. But while the combined mass of all the four inner planets is not quite twice the mass of the earth, the four outer planets together exceed the earth in mass no less than — in round numbers — 450,000 times. Can we possibly regard two families so disproportioned as resembling each other in kind 1 I have been engaged now so many years in endeavouring to persuade students of astronomy, both on « prion grounds and on the more satisfactory evidence of observed facts, that the giant planets are unlike the terrestrial planets even as they are unlike the sim, each forming a definitely distinct class, that though I may say I have now succeeded, I can hardly expect very readily to persuade the general reader that Jupiter and Saturn must be altogether * I was rather interested in this mistake, because on the strength of it, and a kindred mistake about the earth's reeling motion in 25,868 years being similarly caused, I had been taken sharply to task by the editors of " Johnson's Cyclopedia " for not introducing some such explanation of the tides and of precession into the astronomy of the " American Cyclopsedia." Here, wrote my severe and anonymous critic (or to this effect), was our American astro- nomer, all ready with a new cut-and-dried explanation of these phenomena, and Messrs. Appleton pay this " blawsted Britisher " for reproducing the old one. The old one, however, chances to be right ; the new one (as it appeared shortly after in the first edition of " Newcomb's Astronomy ") is wholly wrong ; and even in the very mild and modified form in which it appears In the second edition, it has no value whatever as an original explanation, being only a recondite way of presenting the most unsatisfactory portions of the old one. 58 ♦ KNO^A^LKDGE ♦ [January 2, 1888. unlike our terrestrial home, and must have had in the past, as they will have in the future, quite different life histories. But .such is certainly the case. It might be inferred from what we know of the disproportion of the masses, and all the more certainly from what we have recently learned to consider extremely probable respecting their general resem- blance in structure. (For, unlike collections of unlike materials might by some strange chance have like life his- tories ; but such similar Ufe histories could never occur in unlike collections of like materials, or in like collections of unlike materials.) It is, however, noteworthy how, even within each family of planets — the family of giant planets and the family of terrestrial planets — differences of size and mass exist which suggest marked differences of life history, and also enable us to infer from analogy great differences among the com- ponent members of higher systems, as sidereal systems, systems of such systems, and so on to higher and higher orders endlessly. I have said that the whole of the inferior family of planets is less in mass than twice our earth ; in other words, our earth surpasses all the rest put together. Venus in turn surpasses Mars, Mercury, and the moon together ; Mars surpasses Mercury and the moon together ; each member of the family, in fine, surpasses all those less than itself taken together. Turning to the f^imily of giant planets, we find the same law there. Jupiter surpasses Saturn, Uranus, and Neptune together some two and a half times ; Saturn surpasses Uranus and Neptune together more than threefold ; Neptune surpasses Uranus and all the rest (moons, rings, cfcc.) of the outer system, with the whole system of terrestrial planets and satellites thrown in. {To he co7ifinued.) LARGE TELESCOPES. HAVE been glad to notice that my friend Pro- fessor Young has come round to the opinion I liave been somewhat strenuously maintaining, that the great telescopes which have lately been made are capable of better and more interest- ing work than hitherto has been accomplished with them. I have not seen yet the article itself in the Forum, wherein Professor Young has indicated the value of great telescopes, and the way in which work done with them can increase our knowledge and extend the horizon of astronomy ; but I have before me a characteristic passage fx'om his essay, the tone of which shows clearly that Professor Young fully indorses the views I have expresed respecting the fine telescopes made so skilfully by the Clarkes and others, and (in several cases) presented so generously to astronomers by men or societies of adequate means. " The reasonableness of wanting larger telescopes still," says Professor Young, " is identically the same as that of wanting a telescope at all." This, though somewhat tautologically expressed, is in reality the essence of the whole matter. Astronomy wanted telescopes that moi-e of the universe might be seen and studied, and as far as pos- sible understood ; and each increase of telescopic power has come in lesponse to the longing of astronomy for a wider range of view, increased insight and better understanding of the wonders which lie concealed from ordinary vision in the remote depths of space. When one of these far-seeing eyes of astronomy, promising keener vision than had yet been attained, has been provided, and when one of the observing army of astronomy has been set in charge of it, high expectations are naturally formed respecting the work it will accomplish. No one who under- stands optical laws can for a moment doubt that such a telescope will do more than one of inferior light-gathering power. This is so, even though a smaller instrument be to some degi-ee superior in actual quality ; but as a matter of fact our opticians are improving year by year the quality of their instruments while increasing the size of the gi-eat eyes they make for scanning star-strewn space. Accordingly astronomy has a right to expect that, even though no actual discoveries may be made by means of a new telescope of superior qualities, the details of objects already known will be better examined, and so be more fuUy understood. As Professor Young well says, " It is not possible now to go out at night as some seem to think " — who must be entirely ignorant of the work astronomy has already done — " and pick up discoveries as one would gather flowers in a forest ; but we may be sure of this," the large telescope " will collect data, with micrometer, camera, and spectro- scope, which will remove many old difficulties, will clear up doubts, will actually advance our knowledge— and what is still more important, will prepare the way and hew the steps for still higher climbing towards the stars." The last half sentence may have more metaphor than meaning, more rhetoric than reasoning ; but though we may not quite know how much Professor Young i-eally means by hewing out steps for climbing towards the stars (after all this is not more highfalutin than Horace s " star-striking with his sublime top"), his main argument is sound. A larger telescope, even when used only for going over ground already surveyed with smaller ones, is capable of doing most important and valuable work. The small telescope may dis- cover objects, precisely as the naked eye discovered the sun and moon and planets ; but the larger one will show better what those objects really are, revealing details which before had been either wholly unseen or so imperfectly seen as to be misunderstood. A larger telescope still will show the details of those details, and fresh details, to be still further and more completely analysed when higher powers are applied — if only the larger telescope is zealoTisly applied to such work. Many interesting examples might be cited of the way in which large telescopes properly used complete the work begun by smaller ones. Consider, for example, the discovery of the sti-ange Saturnian appendage which we now know as the ring system of Saturn. As every one knows, it was Galileo, with his little telescope, who discovered that Saturn had something about him which was unlike anything yet seen. Old Saturn, said Galileo, in his fanciful way, has two satellites which attend him on his way. Later, in a more businesslike communication to Kepler, he said : — " Saturn consists of three stars in contact with one another." And last, addressing the world of science, he announced that he had observed the remotest (or the highest, "as it was still the fashion to call the most distant) planet, to be triform — altissimum planetam tergiminum observari. Such was the discovery of the Saturnian ring-system. No larger telescope could rediscover it ; but every increase of telescopic power applied to Saturn has taught us something more about the system. Galileo was never able to understand why the attendants who guided Saturn on his way were so variable in aspect, and still less why, when he looked at Saturn in 1612, he could see no attendants at all. Hevelius, with larger instruments went some way, but not very far, towards interpreting the mystery. He analysed as well as he could the Saturnian changes, and this is his sesquipedalian report of the results he obtained: "Saturn," said he, "presents three various figures to the observer — to wit, in manner following: — first, the monospherical ; secondly, the tri- spherical ; thirdly, the spherico-ansated ; fourthly, the ellip- January 2, 1888.] ♦ KNOWLEDGE ♦ 59 tico-ansated ; fifthly and lastly, the spherico-cuspidated," of which many a popular reader in those days might have re- marked— if thei-e had been popular readers then — what Gilbert's devoted lover remarks of the Tupperian senti- ment : — " A fool is bent upon a twig, but a wise man fears a bandit," Which I know was very clever, but I couldn't understand it, Hevelius meant simply, however — though he expressed himself anything but simply — that t^atnrn looks sometimes like a globe, sometimes like three globes, sometimes like a globe with handles, sometimes like an egg with handles, and sometimes like a globe with projections. Further telescopic research by Huyghens showed that Saturn is surrounded by a flat ring inclined to the plane in which the planet travels. Cassini's larger telescopes showed the ring to be double ; further re.searches disclosed divisions in the outer ring ; then the inner dark ring (semi-transparent, so that the planet's outline can be seen through it) was discovered ; and with each increase of telescopic power fresh discoveries were made, which are going on still, and will doubtless continue to go on for a long time yet to come. Only it is to be observed of this case, as of all such cases, that if each astronomer who was put in charge of each new telescope had been unwilling to examine with it the Saturnian ring-system because already some one else had discovered such and such details, all this pleasing progress wotild have been brought to an end. It will presently be seen why I dwell on this rather important consideration. There is scarcely an object of telescopic study which has not in some such way rewarded each increase of telescopic power and each fresh inquiiy by keen-sighted and earnest observers. Every planet either shows more of detail, or shows the details of its surfoce more clearly, or shows that details supposed to have been seen have no real existence when increased telescopic power is applied to its examina- tion. The stars not only appear in greater numbers under such increase of power, but single stars are resolved into double, triple, or multiple stars ; minute companions are resolved into sets of attendants ; and movements are detected and measured which with smaller telescopes might have escaped notice, or only been recognised after a much longer time had elapsed. The star clouds or nebulae are seen in greater detail with larger telescopes, and indeed many new nebulas are usually discovered when higher telescopic powers than had before been used are applied to the search for them. The structure of comets is more and more clearly shown as larger telescopes are used in the study of cometic mysteries. And last, to return to our more immediate neighbourhood, the study of the sun and moon has progressed very obviously and decidedlj' as larger telescopes have been applied to the details of the surface of either orb. I may take the examination of the sun's surface as illus- trating in a very effective way the advantages to be derived from the use of large telescopes. Galileo, Scheiner, and Fabricius could recognise little more than the fact that the sun has spots on his face at times, and that these spots are carried round in such a way as to show that the sun rotates on his axis. Hevelius noted the maculce or mottling, and the faculce or bright streaks. Wilson recognised the changing appearance of the spots, and the evidence that they are depressions. The elder Herschel recognised the coiTugations. Nasmyth called attention to details which he called the willow-leaves, comparing the appearance to that which would be produced if a number of luminous objects of a form somewhat resembling that of the willow leaf were strewn on a somewhat darker ground.

January 3, 1888.] ♦ KNO^ATLEDGE ♦ By W COAL. Mattieu Williams. THE PKAIX.iGE AND PUMPISG OF COAL-MIXES. HE vexed question of the duration of our coal-fields woxild have been quite settled ere this, had our means of removing the water from coal-mines remained as they were pre- vious to the inventions of James Watt. As I long ago explained, the end of our coal -digging will occur long l)efore our coal-se-ams are exhausted, long before the physical po.ssi- biUties of working the coal are exhausted. It will be deter- mined commercially when the cost of obtaining coal at home exceeds that of importing it from abroad, or of the growing of wood. With the tread-wheels, hoi-se-gins, water- wheels, and other pumping-machines that were in use at the begmning of the last century applied to our present workings, coal would now cost far more than firewood, and, even with the steam-engines that preceded tliose of Watt, it would cost nearly as much. As it is, in spite of all our improvements, there are great well-known coal-seams re- maining unworked, and pi-actically unwoikable, for the simple reason that the cost of removing the water added to the ordinary cost of coal-getting would exceed the market value of the product. All this coal is, in colliers' expressive language, " drowned out." If coal-seams occurred in non-porous rocks, such as granite and compact hmestone, like the marble of Carrara (where I have walked a couple of miles underground without seeing water), no drainage nor pumping would be required, but this is far from being the case ; the chai-acteristic rocks of the coal measures are porous sandstone and shale. Here and there are alternating strata of what the sinkera call " metal," or hard compact rock practically impenetrable to water, but for the most part the rock above the coal permits the in61- tration of much of the rain water that falls on the surface. That which oozes or pours through the sides of the shaft may be resti-ained by " tubliing," as already described, but the water that comes through the roof and sides of the roads and workings must be first collected by drainage and finally removed by pumping or hauling to the surface. There are some few dry coal-mines, of which I shall speak hereafter. The drainage is eftected by the simple device to which I have already alluded, that of beginning to work on the deep, i.e. at that part of the estate where the coal is deepest, and then proceeding upwards along the natural slope of the seam. The water may thus run down the roads or by special drains or " water gates," until it reaches the shaft, which is sunk to a considerable depth beyond the lowest opening of the roads in order to form a sumph or receptacle for the water, from which sumph it is drawn by winding buckets or pumps. Some primitive coal-mines were drained without any winding or pumping. This is possible wherever the seam occurs in hilly districts and Kes at a higher level than the bottom of the valley. In such cases, an adit-level, i.e. a narrow tunnel, may be cut from the lowest part of the intended working, through the side of the slope, into the open valley. The water, of course, flows down this into the river, or in some cases directly into the sea. This is still used wherever the configuration of the counti-y renders it possible, but unfortunately for the present generation, our forefathers have nearly, if not entirely, exhausted such deposits of coal. It is in lead and copper mines that adit drainage is now more available. I need not describe the mechanism of pit-pumps — pumps ai'e pumps everywhere, and are properly described in treatises on such machines. The special feature of coal-pit pumps is their great size in some instances, and the depths from which they raise the water. In old times, when only the seams of coal near to the surface were worked, the simple so-called "suction pump" was used, acting, as in these post-Torricellian days we all know, by the pressure of the atmosphere. But this pressure could only sustain a little more than a 30-feet column of water, and therefore at greater depths, pumping by successive stages, or the use of lift -pumps or force-pumps wiis adopted, or more commonly in tlie early days the water in the deeper pits was raised by winding, by using large buckets that dipped into the " sumph" in the manner I described when on the subject of pit-sinking. Costly as may be the raising of water from coal and other mines, its costliness has made mankind the richer. This cost was the chief stimulant to invention in the birth and growth of the steam-engine. The primitive machines of Papin, Savery, Xewcomen. Leupold, Beighton, and Smeatcm were constructed for pumping water from mines, and the first eflbrts of Watt with his separate condenser were de- voted to the same object. There was a double advantage in this. Not only was the engine especially suitable for such work, but such work reacted with special benefit on the engine which had to overcome a gi-eater deadweight than that of water down in the darkness of a pit sumph. The deadweight of prejudice had also to be b'fted out of the still lower and darker depths of human stupidity, and the inventions brought to the light in spite of the resistance of vested interests. The damaging power of these detestable agents was proved by the fact that they crushed Dud Dudley's great invention of the manufacture of ii'on by pit coal and ruined the inventor, thereby causing a halt of about a century in the progress of this important branch of industry. The impossibility of crushing the steam-engine and its in\entors arose from the fact that its work in pumping water from mines was so easily and obviously measui-able. The quantity of water raised from a given depth by the expenditui-e of a given amount of fuel admitted of such definite statement that misrepresentation was drowned by it. A few figures indicating the progress we have made in this direction will be interesting. When Smeaton com- menced his improvements, the average t, and on whose tomb he inscribed the simple words, '■ A dear, good child," evidence the tenderness of the man- he was fond of animals, courteous even to the more inferior species, known as boi-es; careful in money matters, extending this to the small con- cerns of the villageFriendly Club; he betrayed an anxiety, strange in a man of his wealth, about leaving his children a competency ; there was a curious side of penui ionsness in his economy of paper, from the b.icks of old MSS. to the fragments of .spills. He took snuff when he worked, and smoked when he rested, glad, after the more serious tasks and correspondence of the day were over, to listen to novels, for which he had a great love so long as they ended happily and contained " some person whom one can thoroughly love, if a pretty woman, so much the better." Strangely enough, he lost all pleasure in music, art, and poetry after thirty. When at school he enjoyed Thomson, Byron, and Scott ; Shelley gave him inten.se delight, and he was fond of Shakespeare, especially the historical plays ; but in his old age he found him "so intolerably dull that it nauseated me." This curious and lamentable loss of the higher a>sthetic tastes is all the odder, as books on history, biographies, and travels (inde- pendently of any scientiiic facts which they may contain), and essays on all sorts of subjects, interest me as much as ever they did. My mind seems to have become a kind of machine for grinding general laws out of large collections of facts, but why this should have caused the atrophy of that part of the brain alone on which the higher tastes depend I cannot conceive. A man with a mind more highly organised or better constituted than mine would not, I suppose, have thus suffered ; and, if I had to live my lite again, 1 would have made a rule to read some poetry and listen to some music at least once every week, for perhaps ilie jMrts of my brain now atrophied would thus have been kept active through use. The loss of these tastes is a loss of happiness, and may possibly be injurious to the intellect, and more probably to the moral character, by enfeebling the emotional part of oui- nature.

Before pasting the ends of the 68 ♦ KNO^A^LKDGE ♦ [January 2, 1888. second ring, give the paper a single twist (fig. 2), and before completing the third ring give the strip two twists. These twists in the completed rings (1 nnd 2) will be so much the less perceptible in proportion as their diameter is greater. If we take a pair of scissors and cut through the circum- ference of ring No. 1 in the direction shown by the dotted lines, we shall obtain two rings, as shown in No. 1'. Pro- ceeding in the same way with ring No. 2, we shall obtain a single elongated ring, as shown in No. 2', and with No. 3, two rings which are connected like the links of a chain, as shown in No. 3'.

THE STAR OF BETHLEHEM. F there is one feature of popular converge about astronomy which inrlicates more clearly than another the generally-prevalent ignorance of science, it is the absurd nonsense now so often heard respecting what is called " the Star of Bethlehem." I suppose that at least 2,000 letters must have been addressed to me with inquiries about this non-existent orb. Again and again I am gravely told that the Star of Bethlehem has already appeared, its place of appearance being at one time York- shire or Devonshire, in England, at another Algiers or Con- stantinople or Tobolsk, at another a village in Kentuck}', at another in Buenos Ayres or Rio Janeiro. There are certain times when the Star of Bethlehem is sure to )je discovered somewhere or other. One of these brought with it " Professor " Klein's discovery in Kentucky last summer ; another was distinguished by the discovery of the erratic star by a young lady in Texas last November. Luckily, a j-ear and a quarter must elapse before the same Star of Bethlehem is likely to be discovered — somewhere about March 25, 1889 ; then again after a few months, on or about June (3, we are likely to hear that some village professor or some young girl or some sky-contemplating local lunatic has seen the Star of Bethlehem : after which it will not be till the end of October, 1890, that the mystic orb will be noticed. Napoleon Bonaparte was one of the discoverers of the Star of Bethlehem ; but he made a better use of it than the young lady in Texas or the " professor " of Kentucky. He pointed to it as it shone ftuntly in the heavens by day, and, instead of displaying ignorance, he took advantage of the ignoi-ance of his officers, saying, " That is my star I " prob- ably knowing quite well that the orb at which he pointed was Venus, a world nearly as large as that for a small por- tion of whose surfiice he had stained that surface with the blood of myriads of men. For all the announced apparitions of the Star of Beth- lehem the Planet of Love has been responsible. She always can be seen in full daylight for a few days at the time of her greatest brilliancy. And, although it is nowhere stated in the Gospel record that the Star of Bethlehem was visible in the daytime, it seems somehow to be taken for granted that it did present and will again present this exceptional peculiarity. Yet, by the singular perversity of ignorance, the very persons who look for the Star of Bethlehem by day, proclaim their belief that it is the star which is called Tycho Brahe's — a star which shone out in 1572 in the con- stellation Cassiopeia, and which could be seen all through the night all the 3-ear round in all the countries and places whence people imagine they have seen the mystic orb. Tycho Brahe's star, the situation of which is perfectly well known, even if the very star has not (as is probable) been identified with a catalogued eighth-magnitude star (shown in my large northern chart of 324,198 stai-s), does not pass below the horizon of any place in higher latitude than 2Gi deg. north. Whenever that star changes in brightness even by a single magnitude, astronomers will know of the change and may be trusted to .attend to it ; though not one among their number imagines for a moment that there is the remotest connection between that distant sun, probably at least a hundred years' light-journey from us, and the Star of Bethlehem. The story of Tycho Brahe's star has been so often told, that I shall here say little on the subject, directing the reader's attention rather to the real story of t'ae Star of the Nativity, as related by one who was probably not Matthew, since the Ebionites who accepted Matthew's as the only trustworthy Gospel rejected the story of the Nativity as a later addition, dating probably from about the year 110. The history of Tycho Brahe's star diilers in no important details from that of the equally brilliant temporary star known as Kepler's. It blazed out suddenly close by the star Kappa of Cassiopeia, the faintest of the four stars which mark the back of the Seated Lady's Chair. At firet it was brighter than Venus iit her brightest. This superiority was not due to the fact that the star was visible at night (whereas Venus is never .seen on a dark sky), for the new star could be seen in the daytime. Probably, by-the-bye, it may be this peculiarity of Tycho Brahe's star which has led to the notion that whenever Venus is seen in the daytime the Star of Bethlehem has returned. But it speaks rather ill for the intelligence and information of the general public that because a star which has certiiinly nothing whatever to do with the Star of the Nativity, and which if visible now at all would show all night, was for a while visible in the day- time, therefore another orb which is not a st;ir at all, and which returns periodically to daylight visibility, should be taken for that orb, although the place of Tycho Brahe's star shows in the night time no star even of tiie sixth or seventh magnitude.* The statement that Tycho Brahe's star has been identified with two stars which .shone out respectively in the years 945 and 1264 is far from justified by the evidence. Oa hunting over old records, two were found which very doubtfully suggested that celestial objects which might have been stars, but might also have been comets, had been seen in the years 9-45 and 1264, either of which might have appeared where Tycho Brahe's star was seen, or, on the contrary, might have been anywhere within a distance of 10 or 12 degrees from it. Of course, if these were merely apparitions of Tycho Brahe's star, which I regard as wildly improbable, then since an interval of 319 years elapsed between their appearance, and an interval of 308 years only between the later of the two and Tycho Brahe's star, it is evident the variable is not regular in its returns. And since 315 years have already passed since Tycho Brahe's star was seen, the prospect of a return of the star to visibility is somewhat doubtful, apart from the more than doubtful character of the evidence on which the identity of the stars or orbs of 945, 1264, and 1572 has been based. If, however, it should happen, as it very well may, that Tj-cho Brahe's star should blaze out within the next few years, the general » An attempt was made to save the Texan Star of Bethlehem from detection as an impostor last October by announcing that though it had been visible for several days it had vanished, so that astronomers need not hope to persuade the world that it had not really appeared. But, unfortunately, that self-same supposed star was ijlazing out morning after morning as Venus, the Morning Star, while night after night, all that time, the place of Tycho Brahe's star was absolutely vacant so far as naked-eye vision was con- cerned, and occupied only for telescopic vision by an eighth magnitude star. o KNOWLEDGE ♦ [Februahy 1, 18S8. public may rest confidently assured that its apparition will be in no way connected with the star described in the Gospel of Matthew. As to that record itself, it is singular that any doubt should exist as to its meaning. That the story relates to an astronomical event is of course certain. Had some meteorological phenomenon been in question the narrative would unquestionably have been otherwise worded. The event was certainly astronomical ; the magi were certainly astronomers. Saying this is in eftect saying that the magi were astrologers, and that the event was chiefly interesting in its astrological aspect. Farrar and Geikie in their lives of Christ follow all theo- logians of any weight who have ever dealt with the narrative of the Nativity in admitting this. But theologians seem to bs unconscious, one and all, of the overwhelming difficulty in which this interpretation lands them. "We find them placidly discussing the wide- spread belief in astrological ideas and in the supposed influence of the heavenly bodies ou the aflairs and fortunes of the human race — not as if they were striving to get rid of a great difliculty, but as if the discussion were part of the explanation of the Star of Bethlehem. Not once, so far as my own reading extends (and this subject has been one about which I have read much) does any theologian note that the ideas of astrologers were altogether erroneous, and that confident faith in such fancies implies a degree of ignorance, not to say superstition, which however natural in the beginning of the Christian era, is entirely inconsistent with the belief that this portion of the first Gospel is inspired — as theologians understand inspiration.* But perceiving the absolute impossibilitj' of reconciling the story of the star of Bethlehem and its manifestly astrological significance with scientific facts, we are not merely led but forced to inquire whether some outside origin of the story may not be found. When we find that the Ebionites, though naturally disposed to view with special favour the Gospel of Matthew, rejected the story as foreign to the genuine narrative, we are encouraged to believe that decisive evidence on the subject must have existed in their time, which should bs accessible also to us, since the Ebionites were not profoundly learned. In reality the external origin of the tradition (once the inquiry is suggested) is as obvious as daylight. The story of the star is told, in every detail, of the birth of each of the sun-gods — Osiris, Horus, Mithras, Serapis, and the rest.f But the original myth was not mythical at all. It belonged simph' to the systematic observances which appertained to sun-worship as regulated by an astronomical and astrological priesthood. Each portion of the day deter- mined by the sun's apparent motions was measured by a.stronomical observation, from the dayspring of one day to the dayspring of the next. In like manner each portion of the year determined by the sun's motion above and below the equator was measured by astronomical observations which were in truth religious observances. * The erroneous ideas implied in this part of the narrative are not alone. The " exceeding high mountain " from whose summit " all the kingdoms of the earth and their glory " could be seen is as consistent with the science of eighteen hundred years ago as the star which appeared and disappeared and reappeared and linally travelled before the magi on their seven-mile walk from Jerusalem !o Bethlehem; but it is entirelj' inconsistent with the geography as well as with the astronomy of scientific times. And it is hardly necessary to say that certain passages relating to the end of the world are written with manifest want of appreciation of the require- ments of longitude and latitude and of a rotating world nearlv 200,000,000 of square miles in area. t Doubtless this was part of the evidence on which the Emperor Hadrian, in the year 137, based his belief that the Christians of his day wers worshippers of Serapis. The method of these observations is known, since it remained in vogue long after actual sun-worship had died out, and long after more exact methods of measuring the sun's yearly movements had come into use. Each stage of the sun's annual course was determined by the heliacal rising of a certain star, that is, the rising of the star at such a time that the star was just visible before the approach of the sun to the horizon obliterated all fainter lights from view. In variable climes this method would have no exactness at all. Even in Egypt and Chaldea it w;is but rough. But in point of fact all the methods employed by worshippers of the heavenly bodies were rough : for they were devised when as yet men knew little of astronomy, and they remained sacred afterwards (as always happens in such cases), despite their roughness and simplicity, partly even because of these. Of all the epochs marking the sun's annual course the winter solstice, or the time when the sun's gradual descent below the equator ceases and merges into ascent, was the most important and critical in ancient times. In the earlier days of ignorance men must have feared lest the change would never be brought about, the sun passing away farther and fivrther south till he disappeared for ever, and with him all heat and light and life. The recognition of the fact that their god's southward course had ceased (that he was standing still, as the word solstice implies) restored hope to men's hearts, a hope changed to the certainty that he would return, bringing life back to the world, so soon as it was announced that he was moving northward from his staying place. Later, when the religion of the sun was fairly established, the heliacal rising of a particular star was the sign for which the priests of the sun waited before they announced to the people the birth of the god of the new year. And therefore, later still, in every myth of the birth of the sun god we find this observance forming a prominent part of the story. We have, in foot, in the story of the Star of Bethlehem, a simple repetition of what the priests of the sun actually did. They watched the sun, whose heliacal rising was to indicate the birth of the year god ; as soon as they had seen that star in the east, just before the stars vanished with sun- rise, they proclaimed the good news to the people. The magi, or astrological priests, watched the star in the east ; the magi saw the newh'-risen stars obliterated day after day by the sun of the old year (the slaughter of the innocents) ; the magi traced the course of the star in the east until, just at the time of the solstice (December 25, according to the old system), it came and stood over the place where the sun god of the new j-ear was to be born, just showing above the horizon as his first raj's proclaimed hLs approach. Then the ange's or messengers of the magi announced the birth of the sun god of the year. And lastly, the magi or high priests oflered up the people's gifts of myrrh, frankincense, and gold, all mystically typical of the solar worship — the sun being, in fact, in the old astrological system, represented by gold. Such was unquestionably the manner of announcing the birth of the sun god by observation of the star- of his nativity in sun-worshipping days — the details being essen- tially astronomicitl, or rather astrological. Those who can regard as accidental the agreement between all these details and the details of a story which appears onl}' in one Gospel and \\'as rejected by the ver^- race who accepted that Gospel alone, must attach very little value to the evidence from multiplied coincidences. If the explanation is rejected according to which this account is mythical and interpolated, then we have to accept the explanation given by leading theologians, accord- February 1, 1888.] ♦ KNOWLEDGE ♦ 75 ing to which the story corresponds with the astrological notions, admittedly mere superstitions, of those ancient days.

SHAKESPEARE AND HISTORY. y^Cji^jjMSg^ 1 1 E character of Richard III., in Shake- speare's ])lay of that name, has ever been considered one of Shakespeare's finest crea- tions. Whether we consider the wonderful variety of aspects under which the hunch- backed tyrant is presented to us, or the force and spirit with which each is drawn, we are alike a.stonished and delighted. But this picture, which is so excellent an illustration of the poet's power, is no correct portrait of the third and worst of our English Richards, any more than the bodily distortion attributed to Richard III. is historically just. So much variety of opinion has existed among historians in regard to Richard III., that it is difficult to form an opinion as to the man's leal character. There is no part of history which is involved in so much obscurity as the War of the Roses. Many important incidents which, were they well authenticated, might assist us to form an opinion as to Richard's character, are diflerently stated by historians, or even by some entirely denied. Possibly, I may remark in passing, the question of the character of our English kings may in itself have little interest for our readers, most of whom, I suspect, have gotten over the foshion of regarding the lives of the Kings and Queens of England as the most important parts of history. Men of sense regard our English kings as only important historically because of the immense amount of mischief their rapacity, ambition, and general villany have occa- sioned. Yet Shakespeare's creations are always worth studying, and we cannot but take an interest in the com- jiarisou of the picture of Richard III. drawn by Sliakospeare and the real villain of history. It was perhaps natural that Shakespeare, who wrote at a time when the intellectual progress that had begun when the Tudors were established on the English throne had reached a high development, should form an exaggeratedly unfavourable estimate of Richard III. It was natural that he should contemplate with something of horror a reign whose annals are so dark, and should ascribe to that kmg the largest share of the blame for all that disgraced his time — for the savage manners and the dishonourable con- duct which characterised nearly all the leading men of that age. Another reason, probaljly, for Shakespeare's feeling of intense dislike for Richard III. was that the last king of the House of York was the personal enemy of Henry Tudor, the grandfather of that queen who, with all her faults, was the pride and glory of Shakespeare's time.* * Mr. Donnelly's assertion that the writer of the historical plays hated and even despised Elizabeth is fairly disposed of by the Some historians even confirm the story that Richard III. met his death at the bands of Henry VII.— a story naturally accepted by Shakespeare as dramatically eifectivo ; but there is not a shadow of evidence that they encountered on the field of battle. Had they done so, the event of Bosworth Field might have been difierent. For whatever his faults may have been, Richard was a stark warrior. It is certain, be the explanation what it may, that Shake, speare has drawn Richard's character darker — which was by no means necessary — than historic truth would justify. In the contest between the rival houses of York and Lancaster, Richard acquired early the reputation of a brave soldier and an able general. He does not a])pear to have been at that time in any way distinguished from his brothers, Edward and George, or the young nobility who fought in the same cause. Yet to this part of his life Shakespeare, following Holinshed, attributes two of the most brutal murders — the public stabbing of Prince Edward at Tewkes- bury and the secret murder of Henry VI. in the Tower. Other chroniclers than Holinshed confirm Shakespeare in this, but it is exceedingly unlikely that Richard took any personal part in either murder. In like manner, the murder of Clarence, which Shake- speare attributes to Richard, and represents I^dward as regretting, was almost certainly ordered by Edward alone. Edward was as unscrupulous as Richard subsequently proved to be, and Edward's sitspicions of George show that in all probability the three brothers were fairly matched in this respect. The Plantagenets, as a family, never allowed kinship to interfere with their ambitions, any more than did their Norman predecessors, or the Ttidors, who succeeded the rival Plantagenet houses of York and Lancaster. On the death of Edward, Richard does not at first seem to have entertained any idea of .seizing the crown. He was justified in claiming the protectorate, not only by his near relationship to Edward, but by the general prejudice against the Woodvilles (the family of Edward's widow). But from the moment Richard obtained the regency he was placed in a position in which he found it impossible to maintain him- self without constant watchfulness. The Queen's family began to form plots and intrigues against him. He knew that the authority he possessed while Prince Edward was a minor would not secure him against future dangers. The young Prince, as he grew up, would be most likely to side with his mother. Beside.?, he could scarcely but recall the fate of another Gloster who had held a similar position, and had been murdered when the Prince for whom he had held the reins of power had mounted the throne. It was with such dangers before him that Richard was led to assume the sovereignty, an act doubtless of treachery and villainy, closing scene of " Henry VIII.," when the historical plays merge, as it were, into contemporary history : — '■ The words I utter Let none thinke flattery ; for they'l tinde 'em truth. This Royall infant, Heaven shall move about her ; Though in her cradle, yet now promises Upon this land a thousand thousand Blessings, Which time shall bring to ripenesse ; she shall be (ISut few now living can behold that goodnesse) A Patterne to all princes living with her. And all that shall succeed. Salia v/ii" never More covetous of wisdome and fair Vertue, Than this pure Soule shall be I All princely graces That mould up such a mighty piece as this is, ■\Vith all the Vertucs that attend the good, Shall still be doubled on her.'' With much more to the .same effect. All this in the folio edition, where Mr. Donnelly reads his I'.aconian abuse and ridicule of Queen Elizabeth. Note, moreover, that this was probably written after Klizabeth's death (" Eichard III." was written many years before that event). re ♦ KNOWLEDGE ♦ [February 1, 1888. even though it was thus intended as a means of safety against the treachery and villainy of others. How far the character of his opponents would have justified the seizure of power from them need not be considered. The wrong was done against one who was at least innocent of any actual offence against Richard. Yet we must recognise some distinction between an act of rapacity almost essential to Richard's safety, and an act of villainy deliberate!}' plotted against the innocent Prince, his nephew. Up to this point in his history Richard had been far from encountering that universal hatred which is pictured in Shakespeare's play. On the contrary, he seems to have been rather popular than otherwise ; and his accession to the regency was hailed with delight by the English people. But we enter now on a darker scene, of which this act was the prelude. It rendered Richard at once unpopular. Our English race has always, even in the dajs of its semi- savagery (the good old times, as .some fondly call them), been quickly excited to indignation at the sight of the weak and innocent oppressed by the crafty and rapacious. The executions — murders though they perhaps were — of Rivers, Grey, and Hastings had been so much in accordance with the practice of those pleasant times, that they had attracted little notice and roused still less excitement. But in de- priving the boy-Prince of his inheritance Richard was offending the whole nation, while exposing England to a repetition of those scenes of horror which had but lately ceased, and from the effects of which the country was still suffering severely. Accordingly, Richard found this measure received with so much indignation, and his new power so insecure, that the murder of the Princes seemed to him the only way to protect himself from those who were eager to restore to them their rights. The murder of the Pi-inces was Richard's destruction. The wrath of the English people at his usurpation turned at once into execration ; and thenceforward there was no villainy of which they did not believe him capable, scarce .any known to have happened during the evil days of the War of the Roses of which they were not prepared to regard him as the actual perpetrator. Men could scarcely believe that so iinnatural a murderer possessed the form or attri- butes of humanity. It is difficult, even now, for any one of the English I'ace to do such justice to Richard as should be meted even to so great a villain. We must not forget, how- ever, that — though hanging would have been too good for him — thei-e is a distinction between murder suggested by iin.scrupulous ambition combined with the dread of imminent danger, and that inherent ferocity and brutality, that love of cruelty for cruelty's sake, which characterises the Richard of Shakespeare's creation. It is interesting to notice how Richard's crimes and their punishment were connected. The usurpation by which Richard had sought to make himself secure brought greater dangers with it. The crime by which he thought to pro- tect himself against these led to his overthrow and death. We cannot wonder that even in the semi-savage England of the fifteenth century this should have happened. The light of chivalry, such as it was, had been dimmed amid the disorder and depression of the civil war; yet the nation was not slow to raise its voice in ominous tones against the king who had been guilty of a crime so cruel and so cowardly. Richard himself seems to have begun to recognise the finger of Providence in the misfortunes which now began to frill upon him. His demeanour and gestures during the lattei' part of his life indicated the terrors suggested by a guilty conscience. He continued to oppose with vigour and capacity the plots and intrigues which now thickened around him, but it was with evident anxiety as to the result. He could no longer trust his nearest friends. He could perceive fear and hatred ill- concealed in the countenances of all around him. When the stoi'm which had so long been gathering on the horizon at length burst over him, Richard found the means he had prepared to stay its progress turned against himself. Richard's conduct, however, in this last scene of his life was marked by singular courage and energy. He fought resolutely to the last, and he finally met defeat and death on Bosworth Field with all the valour for which the Plantagenets had long been famous. In the Richard of history, then, we have a man distinctly different from the Richard of Shakespeare's play. Possess- ing energy and talents, and a high position in the nation, Richard III. found himself so placed that these advantages involved serious dangers. There seemed to him to be no middle course : he must either do or sutler wrong. That he chose the former in such an ago, though it must be con- demned, is not greatly to be wondered at. His character has been well summed up in the statement that " he difiered little from the ordinaiy nobleman of his time, except that circumstances gave him the power to perform signal acts of treachery and to profit by them." As regards Richard's capacity there can be no question. Every act of his recorded by history speaks of the man of energy and decision, who amidst plots and intrigues sees at once the best path for safety, and follows it without scruple or compunction. He would probably have failed had he attempted to oppose secret plots with craft and policy. He met them and dispersed them openly and vigorously. In the family of Edward's queen he had to contend with those who, having been raised from an humble condition, enter- tained .a natural aversion to a prince whose family claims were older and stronger. They spared no efforts to bring about his overthrow. We cannot rightly judge, however, of the character of the Richard of history, nor rightly appreciate the Richard of Shakespeare's powerful play, without consiilering the tendencies of that dark and gloomy age. In judging any man's conduct it is always important to consider the times in which he lived, but it is specially so in the present instance. There has seldom been an age whose character has been so marked as was t'nat of the age preceding the Reformation. Generally in each succeeding era of a nation's history the elements of good and evil, of order and disorder, exist side by side — in different degrees, but still actively present, and in some degree counteracting each other. But at the close of the War of the Roses the elements of order seemed to have almost wholly disappeared. The very groundwork of society sesms shaken. The kingly power, the Church, and the nobility, had all at the same time lost their influence on the people, while the people were, as yet, altogether unable to control their own destinies. England had seen the throne occupied by the usurper Henry TV., the rightful king murdered, the lawful heir in prison. After the brilliant but short reign of Henry V. they had seen his son a mere puppet in the hands of the nobility — now in the nominal possession of power, anon flying for his life. It was natural that they should lose that devoted attachment which the kingly dignity had once inspired — an attachment which, worthless though it would be now, was once an important element of the nation's strength. It was the same with the Church. The nation had seen its abuses laid bare by Wycliffe and his followers, and had also felt by bitter experience the change which had taken place fiom the comparative purity of former times. They noted the selfish and often evil lives of many who professed to be their teachers ; they suffered from the rapacity and avarice of the priesthood of the time. We cannot wonder. February 1, 1888.] ♦ KNOWLEDGE ♦ 77 then, that the Church had lost the hold it had once had on the confidence, if not on the aSections of the people. The nobility had in large degree forsaken the chivalry of their forefathers, which, though coarse, was wholesome. They were no longer distinguished from the commonalty by valour or capacity, but only by splendour and luxury. While the old order had thus passed away, the new order which was to replace it had not yet appeared. A sense of insecurity, accompanied by a dis.solution of all restraints of honour, can be recognised in all classes in that dark era of English history. As Hume has well .said, " All that we can distinguish with certainty through the deep cloud which covers that period is a scene of hoiTor and bloodshed, savage manners, arbitrary executions, and treacherous and dishonourable conduct in all parties." If any man in that age had reason to feel its .savagery, or was likely to be in- fluenced by it, it was Eichard. In the earlier part of the civil war his family were treated as traitors and rebels, his father was slain, one brother forswore himself and fought against his own relations, another murdered his traitorous brother, and he hiniself had been compelled to endure and inflict wrongs of the most cruel nature. His usurpation and the crimes which followed it were a very natural sequel to a life-experience so brutalising. Of Richard's domestic life we know little. History gives no sort of support to the stories of domestic villany intro- duced as parts of the picture of the Shake.spearian Richard. It is unlikely that the real Richard was a dutiful son or an affectionate husband, but history does record that he was a loving father. Nay, some historians attribute his worst crimes in part to his anxiety to secure the throne for his son Prince Edward. ARCTIC ORIGIN OF ARYAN RACES. HERE are few developments of the genor.al doctrine of evolution more interesting than those which relate to language. The dis- cussion of the origin of languages and dialects, and their development after they have come into existence, is sufliciently interesting ; but more interesting still is the study of languages in their relation to the past history of races. It is as bearing on the e\-olution and development of races, much more than as bearing on the evolution of lan- guage, that philological researches chiefly interest the student of science. There is one sulyect of special interest in the past history of i-aces on which the stmly of language promises to throw light. Whence did each race first come ? Whence, in par- ticular, did that great division of the human i-ace, the Aryan or Indo-European, to which we our.selves belong, take its origin] Over what regions, again, has this par- ticular stream of human life flowed since first it had separate existence ? Of old, when the more thoughtful strove to deal with such questions as the diversity of language, they gave com- paratively simple answers to such questions as these. It was enough to suppose that all men originally spoke one language, and that that language was miraculously con- founded, insomuch that different sets of men and women (quite possibly different pairs) had to form different races and nations. There w.as no difliculty in all this to primitive thinkers. They could see no special reason why a single pair should not start a thriving race ; indeed, they imagined the process repeated whenever some new race was to be originated, especially when it seemed to them that by such a theory either the importance of their own special family might be enhanced, or the specially undesirable character of their own enemies might be indicated. The question of the origin of Aryan races was one of those with which primitive thinkers dealt in this simple fashion. It was enough for them to conceive the .Japhetic, Semitic, and Hamite races to have sprung from three men, sons, indeed, of one father and one mother, but by special interposition of deity provided with different, nay, widely contrasted racial characteristics. It is to be presumed that, following on this special ordinance, there was understood to have been some arrangement by which the three great divisions of the human race, thus originated, were kept distinct one from the other — besides, of course, that mira- culous ordering of things by which the degeneration of the descendants of a single pair was supposed (if any attention at all was given to this dilficulty) to have been in some way prevented. It is hardly necessary to say that the Japhetian theory of the origin of Aryan races has long since taken its place with students of science beside the Babel theory of the origin of languages. The Caucasian theory of Blumenbach, though it held its ground long enough to give wide circulation to the term Caucasian as a fit name lor the Ai-yan races, has also long been abandoned. But no satis'actory solution had yet been obtained for the problem of the origin of the Aryans. Pott, Lassen, and Max Miiller maintained that the highlands of Central Asia had in all probability been the cradle of these races ; but there was very little evidence to show that this theory was correct. The chief argument used by those who supported it was based on the supposition that Sanscrit is nearest of all the Indo-European languagey to the primitive Aryan — a belief, however, for which the evidence wa.s very slight. We can clearly trace back the course of the Aryans into Lower India from the valley of the Ganges, and into this region from the Punjaub, into which region again they doubtless entered from the Hindoo Koosh. But we can trace them no farther back. It is true that the farther west of India we trace the language the less original we find it, insomuch that we may fairly infer that, while the Aryan Indians migrated to the south- east, the Aryans of Persia and Asia Minor migrated west- wards. For all these sections of the Indo-European race we may find a cradle in the highlands of Central Asia west of ilurtag and Belurtag. But we cannot conclude safely from this that those highlands were the cradle from which the whole Indo-European division of the human family came. The Greek, the Roman, and the Romanic languages may be referred to the same Central Asian source from which the Persian or Iranian and the Sinscrit were derived, and yet it would remain unproved that the Hungarian and Lithuanian languages and dialects were derived thence, and with doubt on this head would come in doubts as to all forms of Teutonic and Celtic languages. Now the researches of Cuuo, Geiger, Schrader, and Penka tend to show with constantly increasing force of evidence, that the languages of Middle and Western Europe were derived from regions lying north and east of these regions — in other words, from the regions around the Baltic. The Rev, Canon Taylor, in a paper of singular interest recently read before the British Association, points out that the evidence indicates the Baltic provinces of Russia, or what we used in old times to call Finland, as the central region from which the Aryan races sprei\d— one great division travelling southwards and eastwards over the central high- lands of Asia, to occupy India, Persia, and Asia Minor ; another travelling southwards and westwards over Prussia, Poland, Hungary, Germany, Denmark, Gaul, and the^ British Isles. Each of these great divisions threw oft' bi-anches in various direction.s, insomuch that we find the 78 ♦ KNOWLEDGE ♦ [February 1, 1888. Aryans who had first spread eastwards extending themselves westwards beyond Asia Slinor to Greece and Italy, while of the Aryans who had first spread westwards, some extended themselves northwards into the Danish peninsula, and then westwards and southwards over the British Isles, France, Spain, and even Africa (where the Kabyles ai-e distinctively Aryan) and others passed from parts of Southern Germany eastwards again. On such points there must ever remain much doubt, but the evidence grows clearer and stronger, year by year, that the real centre of dispersion was in North-eastern Europe, and not in Central Asia. MATERIAL OF THE UNIVERSE. [Concluded from page 58.) TOUCHED in my last on the relative masses of the various members of the solar system, and in so doing considered in a sense their relative might, for on account of that myste- rious power which matter possesses of attract- ing matter we measure the strength of each orb in the universe by its quantity of matter, to which its attractive action at any given distance is strictly proportional. But there are other circumstances by which the import- ance of the several planets, measured by reference to the sway which each is cap.xble of exerting on surrounding matter, is influenced, if not directly determined. For example, consider the power which the sun has of communicating velocity to matter drawn to his sui-face from a distance. In this there is not only evidence of attractive might, but also of potentialitj' in regard to other attributes not less important to the sun regarded as the chief orb of the solar system. For the sun's light and heat, as well as other qualities which he possesses as a radiant orb, depend on this effect of his attractive energy. We do not, indeed, at present attach much weight to a theory once in vogue, according to which the sun's light and heat were regarded as due to the actual impact of meteoric bodies drawn toward him in countless millions from outer space. But the theory now generally accepted, according to which the sun's heat is the thermal equivalent of the mechanical pro- cess of contraction, going on constantly in consequence of the sun's powerful attractive action on the materials of his own globe, does in reality quite as definitely attribute his light and heat to his attractive energy as did the old meteoric theory ; and we may take the velocity he is capable of generating in bodies drawn to him from great distances as aflbrding a measure of his power — one might almost say his vitality — in this respect, quite as confidently as though the direct impact of such indrawn matter stirred his surface to intense heat, and so caused it to glow with intense lustre. Now assuming as I do throughout my book (still in the stage of growth) that the sun's distance is 92,780,000 miles, which I consider probably far nearer the truth than Newcomb's ninetj'-two and one-third millions, I find that his mass amounts to 330,500 times the earth's, and that the velocity with which matter drawn to his surface from an indefinitely gi-eat distance would impinge vertically upon that surface is no less than 382'57 miles per second. It is hardly necess;iry to say that none of his dependent orbs compares with him in this respect. If a body were let fall upon Jupiter from an indefinitely great distance, being drawn to Jupiter's surface by that planet's sole attraction, the velocity of impact would be but 37'37 miles per second. In Saturn's case the velocity would be 22-58 miles per second ; in Neptune's [case 1372 miles; in the case of Uranus 13"25 miles; in the earth's G-913 miles (this represents the velocity of seven miles per second with which .lules Verne's Columbiad had to shoot forth those venturesome travellers to the moon) ; in Venus's case the velocity of impact, always supposing each planet left alone to generate the greatest possible velocity, would be only 6 '218 miles per second: in the case of Mars it would be 3'179 miles; in that of Mercury 2-901 ; while lastly, our small companion planet, the moon, if left to do its best alone on matter approaching it from a very great distance, could not generate a greater velocity than 1-1:82 mile in each second of time — though this, by the way, is a considerable velocity, being about four times the velocity with which a cannon- ball leaves the mouth of the best cannon men have yet been able to construct. Bat no planet is able to exercise its control on an approaching orb in this undisturbed fashion. There is only indeed a comparatively limited region within which the rule of a planet is superior to that of all other bodies, even including the sun. Each planet has in this sense a special domain, the limits of which are determined by the considera- tion that whereas a bodj- outside those limits is drawn more strongly toward the sun than toward the planet, within them the reverse holds, and though it may be but for a time that the planet exerts superior influence, the influence of the planet on a body so situate is greater than that of the sun or than the combined influence of the sun and all other bodies whatsoever. The sun, however, is the only orb whose power in diminishing the control of the several planets over sur- rounding space need be considered, all other influences being relatively insignificant. He aflects the rule of planets in two distinct ways : — First, by his direct power in draw. ing matter toward him more strongly than any planet can, unless the body is comparatively close to its surface ; and secondly, by communicating such velocities to bodies mov- ing within the solar system that even wlien they enter the domain of a planet they remain within it but a short time. Since his power in both respects depends on his distance, or rather on the planet's distance from him, we find the outer planets set in a relatively higher position as independent rulers than the mere superiority of their mass would imply; nay, the outermost of the outer family is set absolutely higher in regard both to extent of domain and influence within such domain than even the two chief planets Jupiter and Saturn themselves. I have calculated the extent of the domains of the several planets, and the velocities with which matter entering those domains would pass through them independently of the action to which they are exposed during their passage. The results are, I think, interesting, presenting, as they do, the relative sway of the difierent members of the solar system in a somewhat new light. All the four terrestrial planets have domains very limited in extent compared with those of the four outer planets. The spherical domain of Mercury has a diameter of only 32,000 miles ; and as bodies which chance to pass through it have velocities ranging up to no less than 42 miles per second, ^Mercury's chance of much influencing bodies passing near him is very small. Oiir own moon, though she has less than a fifth the mass of Mercury, has much more power in this respect, her domain being about 36,000 miles in diameter, while the greatest velocities of bodies passing near her are but 26 miles in a second. Tenus has a domain 106.000 miles in diameter, and at her greater distance from the sun the maximum velocity of passing bodies is reducel from the 42 miles per second Februaky 1, 1868.] ♦ KNOWLEDGE noted in Mercury's case to only 30 miles. Our earth has a domain about 3l'2,S00 miles in diameter, and the maximum sun-imparted velocity of bodies entering that domain is 26 miles per second. As the span of the moon's orbit is neai-lj- 478,000 miles, the moon is not within the earth's domain, nay, lies 77,500 miles beyond the range within which the earth's rule is supreme, so that the moon is to be regarded as a companion planet rather than as a mere satellite. Mars is the only member of the sun's special family of planets — for so I think we must consider the terrestrial planets to be — which has dependent bodies under its own special influence. For the domain of Mars is nearly 165,000 miles in diameter, while his satellites travel at dis- tances of only 5,820 miles and 14, GOO miles, respectively, from his centre. At the distance of Mars the greatest velocities of passing bodies, so far at least as solar influence is concerned, amount to 21 miles per second, and Mars can do little to perturb bodies moving so quickly, even though their course should carry them through the very midst of his domain. So soon, however, as wo pass to the wide region within which lie the paths of the giant planets, we find planetary domains far wider in extent and wherein planetary in- fluences are exerted under conditions much more favourable. The domain of Jupiter has a diameter of nearly 30,000,000 miles, within which the whole system of the Jovian satel- lites, the span of which is but 2,800,000 miles, is swayed by the planet's supreme influence, slightly modified by the sun's perturbing action, indeed, but only in the same sense in which the motion of the earth around the sun is modified by the perturbing action of Jupiter. The domain of Saturn is even larger, but so slightly that one may speak of the domains of Jupiter and Saturn as practically equal. (Their actual diameters are, respectively, 2t), 824, 000 miles and 20,912,000 miles.) And though the Saturnian system of satellites has nearly twice the span of the Jovian system, the diameter of the orbit of his eighth .satellite being no less than 4,500,000 miles, yet this system is as completely under Saturn's control as the motions of the terrestrial planets are under the control of the central sun. Matter which has entered within these two nearly equal domains travels with sun-imparted velocities ranging up to eleven and one-half miles jier second in the case of Jupiter and to eight and one-half miles per second in the case of Saturn. Over matter so moving both Jupiter and Saturn may exert very consider- able influence, modifying not only the direction of motion, but also — which is a point of much greater moment — its velocity, and so modifying the span and period of orbital motion which such matter may have had around the sun. It is to be noticed that not only is the domain wide in each case within which either Jupiter or Saturn exerts superior influence, but the comparativeU' slow motion of sun- influenced matter through that domain causes the matter which has entered it from without to be much longer sub- jected to disturbing influence than it would be if it rushed along there with the velocities of 21, 26, 31, or 42 miles per second with which matter crosses the domains of Mars, the Earth, Venus, and Mercury. In this respect Uraniis, with a smaller domain than either Saturn or Jupiter, and weaker influence within that domain, has an advantage over both those chief giants of the solar system. For the greatest velocity (sun-imparted) with which matter can pass through the domain of Uranus falls short of 6 miles per second. The span of the domain of I'ranus is not far short of 24,00(1,000 mUes, and the system of Uranian satellites, the span of which is about 1,000,000 miles, lies well within the limits of the Uranian domain. But Neptune is, of all the members of the solar system, the one whose domain is widest, and whose influence within his domain is most strikingly pai'amount. This domain has a diameter of more than 40,000,000 miles, and in volume it is nearly equal to all the other planetary domains put together. Matter passes through this domain when entering it by chance from without under solar influence only, with velocities which range no higher than 4| miles per second ; and as Neptune is so powerful that matter drawn to his .surface under his own influence alone would have a velocity of impact amounting to 13f miles per second, it is evident that Neptune must be capable of perturbing the movements of such matter in very large degree. Such are the relations of matter as we find it distributed within our solar system. A total quantity of matter sur- passing even the tremendous mass of the eai'th no less than 331,000 times appears in this system aggregated into various discrete masses, nearly all, however, being at the centre, whence it may not only influence but warm and illuminate all the rest. We see the various masses, according to their amount and position, exercising sway over larger or smaller regions of space, and over more or less important subordinate .systems. We note, further, the antecedent probability — and the evidence obtained by observation assures us of the actual fact — that the larger these several masses are, the more they retain of the heat due to the primary process of their aggregation, the more nearly do they resemble the chief mass in their power to warm — possibly in their power to illuminate also — the bodies circling around them. If these details of our solar system were not, though I think thev are, most interesting in them s si ves, they would be made supremely interesting by the comideration that each one of the stars tells us of an aggregation of matter re- sembling our solar system doubtless in origin, though the circumstances of their formation may have led to difl'erent details alike of distribution and condition. Here in our solar system certain processes acting according to the known law of universal gravitation, and also according to those physical laws on which the generation of the so-called physical forces depends have led to the gathering together of an enormous central mass with the generation and steady emission of immense quantities of light and heat. Yonder in space we see in each star evidence of the steady emission of immense quantities of light and heat, assuring us of the past aggregation of immense quantities of matter. Our solar .system is the one case we can actually study of the aggregation of matter under laws not yet clearly recognised, and still farther from being fully inter- preted. It may perhaps be in one sense as hopeless to endeavour to guess how other such aggregations have been formed as it is to endeavour to ascertain from our earth's life history the life histories of her fellow-worlds, or from the condition of our moon the state of all such orbs as have, like her, passed onward to the final stage of orb life, the condition of death. But even as from the laws of the life of any one animal we ain form a general idea of the laws of the lives of other animals, and as the study of one plant afibrds data for the determination of the general laws of plant life, so we may fairly infer the general nature of the final stage of orb life from the condition of our moon, the general laws of world life from the life history of our earth (so far as we have been able to read it), and lastly the general nature of other sun-circling systems from the study of the distribution of matter within our solar system, and the state in which the matter so distributed exists, whether in the supreme central mass, in the larger or smaller among the subordinate masses, or in the relatively minute sub- divisions of the original material of the system which wo recognise in asteroids and satellites, in meteorites, aerolites, and finally in the particles of mere cosmical du.st whoso presence is attested by the phenomena of falling stars. 80 ♦ KNOW^LEDGE ♦ THE ONE-SCALE ATLAS.

RUDLER gave an admirable lecture on Tuesday, the 17th inst., on "Caves and Cave Men." The lecturer began by saying that the London clay, gravel, and sand are too soft to admit of the formation of caverns, which occur chiefly in the chalk and lime- stone. He showed, by photographs of the rocks near Flamborough Head and on the Dorsetshire coast, how the destructive action of the waves, keeping up a perpetual cannonade of small stones against the cliffs, washes away the softer portions of the rocks so as to form caverns. Water acts also by dissolving the chalk. The rain-water absorbs carbonic acid from the air, which enables it, as it trickles through the fissures, to dissolve a little of the chalk or limestone, thus gradually enlarging the fissures till it forms large caverns. Mr. Rudler, with the help of some beautiful photographs, explained how the water, charged with limestone, drips from the roof and forms stalactites and stalagmites — the former resembling icicles hanging from the roof, the latter formed underneath them by the drip, and rising in conical masses from the floor, or sometimes consolidated into a floor of remarkable hardness. The cave of Gayleureuth, in Cxermany, is of this kind. Under the stalagmite floor is a red-brown loamy earth, which has been long known to contain bones. Goldfuss and Cuvier discovered that these were the bones of extinct animals. In 1822 the skeleton of a lai-ge animal was found in a lead-mine in Derbyshire, and this proved to be the skeleton of a rhinoceros, an animal now found only in Africa. In the cave of Kirkdale, in Yorkshire, were found an immense number of bones, which Dr. Buckland ascer- tained to be chiefly those of the hyena, now met with only in Africa and Asia. Other bones which were found with them appeared to have been gnawed ; and, comparing these with bones gnawed by hyenas in Wombwell's menagerie, Buck- land found that they had been gnawed precisely in the same manner. Clearly, then, this had once been a den of hyenas. Other animals of which bones have been found in this or other caves are the cave-bear, the cave-lion, the Irish elk, and the mammoth. What this latter animal w,as Hke we are not left to infer merely from its skeleton, for a carcass of one was actually found in Siberia so perfectly preserved by the ice in which it was imbedded that dogs ate some of the flesh. It was a kind of elephant, with long curved tusks and long hair, fitting it to live in comparatively cold climates. Was man living at the time when these animals existed here ? Other caves enable us to answer this question in the affirmative. In 1852, Professor Boyd Dawkins found in Wookey's Hole, in Somersetshire, together with bones of the hyena and cave-bear, a number of stone weapons, evidently chipped and sharpened by the hand of man. In Kent's Cavern, at Torquay, are two distinct strata contain- ing bones, separated by a floor of stalagmite 2 feet thick. The upper layer contains stone imjJements much less rude in con.struction, evidently the product of a higher stage of culture, together with needles and fish-hooks made of bone, and also the skull of a very formidable kind of tiger. These early men were not without some knowledge of art ; for we find scratched on some of their bone implements very toler- able representations of the reindeer, the mammoth, and the Irish elk, and even of a hunt, with the figure of a man. The cave-men appear to have lived by hunting and fishing, with weapons of stone, bone, and wood, and to have clothed themselves with skins, which they sewed together with bone needles. When men took to agriculture and learnt to build huts, they, as a rule, no longer lived in caves. But caves have been used in later times as rallying-points, or for purposes of concealment or defence, or as places of sepulture. The lecture was illustrated by excellent lantern views. It was listened to with profound attention, and greatly applauded at its close. The chairman, Mr. Marshall, announced that the lecture on the 24:th inst. would be by Professor Bonney, F.R.S., on " The Oldest Monuments in Britain and Brittany." We understand that he will be followed, on the 31st, by Professor Ram.say, on " Speech made Visible; or Picture-writing as it was and as it is"; and that on February 7 Dr. Percy Frankland will lecture on "Germs in the Air"; and on February 14, Mr. E. Wethered on " Volcanoes and Earthquakes." M. C. Martineau. 1 Clifton Place, Sussex Square, W. NOTES ON AMERICANISMS. Grist. A large quantity. So far as I know, this term is not used in this sense in England, even as a provincial expression. Grit. A term for strength of character. It probably had its origin in districts where grindstones or millstones were much used ; for the value of these depends on their strength or hardness of texture, and only sandstone pos- sessing good qualities for grinding can properly be called iirit, or be said to have f reply to a correspondent (Mr. J. E. F\,oose), J! rsf, I do not think the sun will ever be inhabited, but I do not know; secondli/, the central orb of the universe, if such an orb there is, needs no centripetal force to keep it in its place, but I do not think there is such an orb, though here again I do not know ; thirdli/, I suppose when our system dies it will still obey the laws of gravity, seeing that a dead lion is as obedient to these as a live dog ; and fourthly, I cannot tell why our earth's shining in past ages on an inhabited moon, if our earth ever did so shine, is to be represented " for the sake of argument " by " the reversed position " of a globe fifty times larger than ours (why larger?) shining upon the earth. There i.?, however, no "scientific opinion about the moon's having been inhabited," for " knowledge is of things we see." I HAVE received several interesting and valuable com- munications respecting Mr. Faith's article about " Collisions at Sea." One of these I published last month ; another I publish this month ; and I have still a third which will interest readers of Knowledge. * * * Americans of sense are relieved to find that those in their own country who took interest in Sullivan are matched by at least an equal proportion of persons in the old country taking interest in one who would be almost a match for a gorilla. Yet how much more interesting if the gorilla itself could be trained to pugilism ! * * * The Saturday Review remarks of me in a recent issue that I do not love it, while — Safurdai/ Eeviler though it has been called by the profane — it dislikes nothing and no one. I dislike many things myself : among others, untruth and unfairness. But to dislike a paper or a magazine would be preposterous. I know enough of journalism to be able to distinguish an article written by a student and a gentle- man from one written by a charlatan and a humbug, or from another written by a soured " old woman " of either sex, even though all three articles appear in the same paper'. Averaging my ideas about the Saturday Revieio as I have had occasion to regard it personally, I have rather a liking for it, for I have had occasion to observe in its pages — (1) Ple.asant and strong notices of my work ; (2) pleasant, though unfortunately weak, notices ; (3) unpleasant notices, iLseful as giving me an opportunity of correction (with or with- out use of the thong) ; and, lastly, some notices, so manifestly unfair or so femininely spiteful that they were their own severest corrective, and could do me nothing but good, whether noticed or left alone. [I personally very seldom adopt the afl'ectation of " letting abuse alone " — I " go for it," as my American friends say, enjoying the work heartily, and striving to do it thoroughly.] Febrcaey 1, 1888.] ♦ KNOWLEDGE ♦ 91 Ix the Jatakas, or Buddhist Birth Stories, so called be- cause they narrate the exploits of the Buddha in the 550 births through which he passed before attaining Buddha- hood, there is a story called the " Flight of the Beasts," which the recent ridiculous scare in Birmingham — the " Brummagem scare," as we may name it — calls to mind. * * * This Daddabha Jataka tells of a hare who, sitting under a cocoanut sapling, thought to himself, " If this earth were to come to an end, where should I be, I wonder ? " At that moment a bilra-fruit fell upon a leaf of the sapling, and so startled the hare that he scampered away, thinking that the event was really happening. Another hare, seeing him run, and learning the cause, started off; then a third and a foui-th hare took to flight without knowing the reason, and so on until one hundred thousand hares in like manner followed their example. Likewise all the other animals who .saw them, asking the meaning, went at headlong speed, and as the Bodisat chanced to see them, and heard what fear caused their flight, he bethought himself how to save them from destruction. So rushing with a lion's speed, he out- stripped them, and then roaring a lion's roar, so that they halted aflrighted, he asked them why they ran. And the elephants replied that they knew not what was the sign of the end of the world, but that the lions knew ; and in like manner one beast after another answered until they came to the hares, and last of all to the first hare, who told the Bodisat of the falling of the bilra-fruit. The Bodisat then took the hare on his back, and bounded along to the forest where grew the sapling, when, as it chanced, a bilra-fruit fell upon the sapling, and the Bodisat returned with the hare to the assembled beasts, whom he dispersed with words of comfort. At Birmingham the bilra fruit fell in the shape of an astrologer's propbecj- that dire things would happen on January 11 by reason of the conjunction of Mars and Uranus. The old women (were they, after all, hares en- chanted for the nonce into human shape 1) scampered to the police stations, and, foiling to get support or comfort from the constables, clubbed their pennies together and bought Bibles. Others stayed in their beds, their faith in the prediction confirmed by the Cimmerian fog that enveloped the town. And thLs is a.d. 1S88 1 * * * OcR readers may like to know that Messrs. Longmans announce the publication of Mr. Edward Clodd's " Story of Creation " in the early part of this month. The substance of the book appeared in this Journal, but the chapters have teen revised and in great part rewritten, while the text has the advantage of being illustrated by numerous woodcuts and diagrams. The price of the book is six shillings. t .Jolly, F.R.S.E., F.G.S. (London : Blackie k Son.) — A more ad- mirably common-sense little book than Mr. Jolly's has not recently appeared. It ought to be in the hands of every teacher of geography in the kingdom. The Physiological Effects of Artificial Sleep. By Dr. Mathias Eoxri. (London : Bailliere. Tindall, i Cox. 1887.) — Dr. Both has great faith in hypnotism, or artificially induced somnambulism, as a cure for various forms of neurotic disease, and in his small pamphlet gives a selection of cases to show how wonderfully efficacious this mode of treatment has proved. His brochure is worthy of stud\- by all labouring under any form of nervous complaint, from the but too familiar neuralgia to those more obscure species of disorder in which the mind is more or less affected. Humanism versm Theism is a series of letters by Egbert Lewixs, M.D. (London: Freethought Publishing Company. 1887.) — There is no God but Lswins, andXaden is his prophet, may fairly be held to summarise the contents of this queer little tract. Mr. Montague Tigg in " Martin Chuzzlewit " " didn't believe that he didn't believe, hang him if he did," and Dr. Lewins seems drifting rapidly in the Tiggian direction. Pneumatics. By Charles Tomlixsox, F.R.S., F.C.S. Fourth Edition, enlarged. (London : Crosby Lockwood ife Co. 1887.) — Few writers in the present day possess the art of popular scientific exposition in a gi-eater degiee than Mr. Tomlinson ; and in this fourth and enlarged edition of his well-known treatise on pneumatics, in " Weale's Series," he worthily sustains his reputation for rendering somewhat recondite physical questions easily intelligible to the reader ignorant of mathematics. The Practical Engineers Handbook. By Walter Hlttox, C. and M.E. (London : Crosby Lockwood & Co. 1887.) — Arranged in a very convenient form for reference, Mr. Hutton's excellent cyclopaedia of modern engineering workshop pi-actice leaves nothing to be desired. Amoly illustrated by no less than 371 woodcuts, and brought down in every department to the latest date, this is a volume which should be upon the shelves of everyone engaged in any of the numerous branches of modern mechanical engineering. The Modern Treatment of Disease by the System of Massage. By Thos. S. Dowse. M.D., F.R.C.P. (London : Griffith, Farran, Okeden, k WeLsh. 1887.)— Among the ; latest of medical " fads " the treatment of disease by rubbing, pounding, and kneading the human body occupies a conspicuous place, and in the volume before us Dr. Dowse instructs us in the methods of '-effleurage," "'petrissage," " tapotement," and so forth. This used, we imagine, to be called sham-pooing, but possibly we have arrived at the real thing at last. If, though, we ever, for our sins, were com- pelled to undergo this peculiar process, we think that, like Sarah Battle, we should prefer " a quiet rubber." Recent Advances in Ehctricity. Edited by Hexrt Greer. (New York. 1887.)— In a series of articles by the editor of the Ekctrician, Professor Thomson, and Professor Edison, an account is given of all the more recent advances in applied electricity ; and we have illustrated descriptions of the latest devices for electrical storage, of the method of telegi-aphing from a train in motion, of a navigable balloon or air-ship electrically propelled (with a cheerful engraving of the destruction of a town by shells or bombs dropped from the car thereof), of Mr. Edison's contrivance for the production of electricit)' direct from fuel, and so on. This pamphlet will be found useful by all engaged, either prac- tically or theoretically, in the study of electrical science and art. Bulletin of the United States Fish Commission. Vol. VI., for 1886. (Washington. 1887.)— In the 471 pages which make up this volume will be found an enormous mass of detail in connection with the breeding, rearing, catching, curing, and even cooking fish, derived from information supplied from all parts of the world. The interest and importance of this will become apparent when we reflect upon the incalculable wealth of food which fish might supply, and to how very limited an extent we avail ourselves of it. There is a certain fitness in our receipt of this valuable work at the time when an Anglo-American Com- mission on International Fishery is sitting in the United States. The Microscope in Theory and Practice. Translated from the German of Professor Carl Xaegeli and Professor S. ScuwEXDENER. (Loudon : Swan Sonnensehein, Lowrey, ife Co. 1887.) — This translation of a portion of Xaegeli and Schwendener's well-known work (partly made by Mr. Crisp, though mainly by Mr. J. Mayall, jun.) may supplement our leading English text-books, but will assuredly never supersede them. At almost inordinate length, its anthora enter into details a large proportion of which are to be found in such books as Dr. Heath's admirable " Geometrical Optics," to the exclusion of matter of much moi-e real interest to — because le=s accessible by — the observer with the microscope proper. The small part of the volume devoted to technical microscopy is huddled up to make room for all this and cognate matter on polarisation. The portion on testing the optical power of the instrument would be useful to our opticians, but for the fact that the)- happen to be familiar with it already. The really valuable part of the book is that which is explanatory of microscopic vision, and which treats of the theory of microscopic observation generally. All those who conceive that the images of the markings on a diatom are produced in the same manner as that of a church spire in a landscape viewed with the naked ej-e, should study this portion of the work before us carefully. The}' may do so profitably and with advantage. Sprains. By C. W. Mansell Moulix, M.A., M.D., F.R.C.S. (London: H. K. Lewis. 1887.)— It is a common saying that a simple fracture is not half so had as a serious sprain, although undoubtedly in a large number of cases the gravity of the latter form of injury is too much underrated. As Dr. Moulin says in his preface 94 KNOWLEDGE ♦ [Febeuaey 1, 1888. to the excellent and thoroughly practical little volume now before us, " It has been sniil, and not untruly, that in all probability half the t-rippleil limbs and stitiened joints that are met with every day date their starting-point from the occurrence of some apparently trivial accident of this description." It is, then, to a practically exhaustive account of the nature and treatment of this grave form of lesion that our author devotes his work ; and, although addressed primarily to the surgeon, it is written in such perspicuous and untechnical language that the layman may read it both with pleasure and protit. Dr. Moulin advocates more active modes of treatment (including galvanism, massage, pressure, &c.) than those ordinarily .adopted ; and no one can, we think, rise from the perusal of his book without being con- vinced that his ideas on this subject are justified alike by science and by common-sense. Sound, Light, and Heat. By Mark R. Wright. (London : Longmans, Green, & Co. 1887.) — Earth Knoic- ledge. By W. Jerome Harrison, F.G.S., and H. New- land Wakefield. (London : Blackie & Siou.)^Mineralog>/. By Frank Rutley, F.G.S. (London : T. Mm-h j.)— Euclid, Book II. Arranged by A. E.

Capel, M.A. (London : Joseph Hughes.) — The mass of educational works whose titles we have grouped above are all more or less directed to the fur- therance of that vicious system of examination whose ultimate result can only be that of cramming the rising generation with everything and teaching them nothing. The first three books on our list, however, are I'eally too good for their professed purpose. Mr. Wright has boiled down Tyndall, Sedley Taylor, and Ganot in a fashion calcu- lated really to impart a considerable amount of sound infor- mation. The " Earth Knowledge " of Messrs. Harrison and Wakefield is an honest and readable treatise on the bastard science of " physiography," and as absolutely superior to a volume bearing the latter title, recently issued from South Kensington itself, as it is possible to imagine. Mr. Butley's " Mineralogy," too, contains a very large amount of informa- tion indeed compressed between its two covers. The rest of the works specified demand no special notice.

Nobody is infallible, and the player who makes the least number of mistakes is the strongest player. In Tournament play every mis- take counts, whereas in match-play it does not to that extent, for if a player loses a game in a match, he can always recover himself if he is the stronger player. The following incredible series of mis- takes occurred in the game, Gunsberg r. Burn, played in the Tourna- ment of the B.C.A. Bubs.

White has made three successive weak moves, and under certain awkward circumstances such play might give rise to grave conjec- tures. The result of the loss of this game was that Gunsberg was not absolute first, but tied with Burn. Experience has proved that luck sometimes equalises itself. Having had bad luck in the above game, Gunsberg had a piece of good luck in his game with Bird, which, although it did not fully counterbalance the loss of the previous game, yet it enabled him to remain in front. The position was as follows : — GUXSBERG. Black. Whitf. Eir.D. Black had been lighting an up-hill game for a long time, and had no chance by correct play. He played Kt to Q3, which gave White the opportunity of mating in two moves by Q X P (ch), K X Q, and B to Kt2 mate. White, however, did not see this pretty but by no means so verj' obvious move, but played BxP, an inferior move, to which Slack replied with KtxB P X Kt Q to R7 (ch) and wing. Even on his last move White would have done much better by playing Q X Kt, when the win would not by any means be assured b3" Black exchanging Queens, as White would remain with too many Pawns.

Ruffing and Foecing. {('tintinned from p. -17.) HEN your partner shows a weak game, force him, whether or not you would otherwise be right in so doing. It is seldom right to refuse a ruti' when j'our partner, if a good plaj'er, visibly intends you should do it ; if he is a bad player your own hand should direct you. Should your partner refuse to trump a certain winning card, try to get the lead as soon as you can, and play out trumps immediately. When 3'our partner plays a thirteenth card, and most of the trumps are unplayed, he generally means you should put a high 1 rump to strengthen his own hand. [Either leave the card alone, to draw a trump from fourth hand, or trump with }"our best.] I'LAY OP Teumps. Take every opportunity (when sufficiently strong) to show your partner that you can command the trumps. In that case he will keep his own strong suit entire ; whereas if the strength of trumps were with the adversaries, his play would be to keep guard on their suits, and to throw away from his own. [We have here, again, the true principle of the discard as determined by the posiiion of trump strength.] If you have, as fourth player, to win a small trump, and you hold a sequence of three or more, win with the highest and play the lowest afterwards [thus informing your partner of your strength] Keep the trump card as long as you can when your pariner leads trumps [or when you are strong in trumps yourself] ; the contrary if an adversary leads them. Thus, in the former case, if the eight is turned up and you have the nine, throw the nine [when one or other of the two is to be played] ; in the latter case, play the card turned up, even though you have the seven and six. It is equally advantageous to lead up to as through an ace ; less advantageous to lead up to a king turned up ; and disadvantageous to lead up to the queen. It frequently happens when you have Jed from six trumps, that after your second lead you remain with three or four cards, the best being in an adversary's liand. In such situations play a small trump. This has two advantages — first, it prevents the stopping of your partner's suit; and secondly, it gives you the tenace in what- ever suit the adversary may lead. This, mutatis mutandis, will show that it is bad play to lead the best trump, leaving others in the hands of your adversaries. It may do good to keep it in hand, as you may be able to stop an adversary's suit with it ; and it can answer no good purpose whatever to play it out. [The last statement is, however, too general, and is indeed flatly contradicted by Mathews's own statement in another place, where he says] If, however, they both have tiumps and your partner none, it is right to take out two for one [though this in turn is too general, for often you play the enemy's game in so doing. Nothing but practice and experience can show what is best in particular cases. Still the general rule remains sound.] If you remain with the best trump, and one of your adver- .>^aries has three or more, do not lead your trump, as it may stop the suit of your other adversary. Moderate players have generally a decided aversion to part with the best trump, though single, thinking that as they cannot lose it, and it can make but one trick, it is immaterial when it does so [and misled also in many cases by the hope of drawing two trumps from the enemy with it, if they can lead it instead of rutfing with it.] This is a dangerous fault [though in cases, of course, it may lie judicious, never essential; usuall)'] When your adversary plays out his strong suit, ruff it immediately rather than give his partner an opportunity to ihrow off his losing cards. Do not, however, go into the contrary extreme, or trump with the best trump, with small ones in your hand, for fear of being over-trumped. This is a nice part of the game, and can only be understood by practice and attentive reasoning. The last trump is often of most material advantage to a good pl.ayer. Thus, A has the thirteentli trump, with the ace and four small ones of a suit not yet played, of which the adversary leads the king and queen ; by passing them both, A probably makes three tricks in tlie suit, but had he won the king he could not possibly make more than one. He might safely win the C|ueen, however, and take out a third round, trusting to his thirteenth trump to bring in the remaining two, which would then probably be long cards in the suit. Without the thirteenth or a sure trump re-entering card A could not probably in any play make more than one trick in the suit. When all the trumps are out, if you have the commanding card of your adversary's suit, you may play your own suit as if you held the thirteenth trump. If the trumps remain divided between you and your partner, and you have no winning card yourself, it is good play to lead a small trump, to put the lead in his hand that he may play off any leading cards he may have, and so give j'ou an opportunity to throw away leading cards. For ir^st.ince, A remains with two or more trumps and two losing cards; B, his partner, with a better trump and two winning cards. It is evident that if A plays a losing card he will make merely his own trumps ; but if he plays an inferior trump, and so puts the lead into his partner's hands, B will play his winning cards, while A throws away his losing ones. [The ques- tion is only of one trick if A only holds two trumps and two losing cards ; but if A holds three trumps and two losing cards, his partner also holding two losing cards in the same suit or suits, A loses two tricks if he leads a losing card.] SCIENCE IN WHIST. Mr. Ram writes to us again as follows : — " If a whister, who claims to play a game which may be legiti- mately styled 'srientific,' were atter, say, the fourth round of each game, to put in black and white a list of the cards which he opined were in each of the other three hand*, and were at the same lime to make a forecast in detail of what the play of each of the four players for the remainder of that game would in his opinion be ; and at the end of the said game were to com|:iare the document with a coresponding statement which had been made by a fifth person who had actually seen the cards, how long would he con- tinue to style his play ' scientitic ' ? ' Five of Clubs ' allows that ' bad ' play may be successful against ' good ' play for daj-s together ! In what proportion of games would a bad chess-player beat a good player ? Is not the play in whist necessarily always a mere muddling along ? " Whist is no " mere muddling along," as Mr. Ram would find if he knew anything of the game. Since he evidently does not, it would be idle to attempt to convince him. As to his question, I simply reply that the experiment he suggests, if tried at a table where all the players knew the game, would quickly shew even those who know little of whist the value of scientific play. Where two partners play scientilically again.«t two who know little of whist, the infiuence of science is increased, though the power of reading all the hands is diminished. Alheit, it very seldom happens that among even the best players the first four rounds show the position of all the chief cards. Usually nearly all is learned by about the middle of the hand, after which nearly everything depends on strategy. But sometimes the position of several important cards remains hidden nearly to the last. Even then, however, the scientific player can tell the relative chances that such and such cards lie in such and such hands ; and if he then plays according to his estimate of the chances, he is playing scientifically, and will come out right in the majority of instances. When whist is mere muddling along, as, doubtless, all the whist Mr. Ram has ever played has been, the game is wearisome in the extreme. I do not care to sit down myself to play whist when even one of the four players is ignorant of the language and science of the game. With two such players as opponents, and a good partner I should be sure of winning heavily in the long run But it is infinitely pleasanter to be so matched by good play as not to win heavily or at all, in a series of games sufBciently long to eliminate llip effects of chance. N.B. — Mr. Ram can never tell the difference between scientific whist and bumblepuppy till he has played as one of a whist party, all four of whom are sound players. Contents op No. 27.

N old times men looked round upon the eartb, seeing there the whole world, the kingdom over which the gods ruled, while in the heavens above they recognised the temple in which their gods abode and were enshrined. There is something strangely impressive in the thought of what earth and heaven must have been to men in those days. We talk of myths doubtiugly and coldly, because we cannot readily place ourselves in the position of those who were moved to make myths. We cannot readily picture to our minds what they not only paw, but felt; what — if we consider their position aright — we see they could not help feeling. The grave busi- ness man is as unable to recall the fancies of his two- year-old childhood, and s3 interpret the feelings of his two-year-old child, as the more advanced races of man to-day to recall the feelings with which the child-man con- templated the mysteries of earth and sun and moon, and the yet more marvellous mystery of the star-strewn heavens. Our school children can at least verbally describe the globe of the earth ; they can name the great distance separating us from the sun, and speak of his size and might and power ; they can tell how Copernicus and Kepler and Newton ex- plained the strangely seeming movements of the planets. But grown men in old times could not inteipret aught they saw. To them the earth's renewal of life year after year was a standing mystery ; the sun, as day by day he renewed bis victory over the powers of darkness, yet day after day sunk to seeming death in the blood-stained western fields, was as a living, acting, and enduring being, a veritable giant l)ower, rejoicing as a giant to run his course. The moon seemed of set purpose to bear sway over the skies of night, as month after month she returned to full midnight glory, and though she " nightly changed in her circling orb,'' waxing and waning in power, even in this her individuality and self-power seemed attested. She seemed to measure time for man, as if specially considering bLs wants. Even more strikingly did the planets, as they pursued Their wandering course, now high, now low, then lr!cl, Progressive, retrograde, and standing still, peem to exercise powerful sway over the destinies of men. It was not merely, as Wordsworth sang, that those " radiant Mercuries " Se?med to move, Carrying throngh ether, in perpetual round, Decrees and resolutions of the gods, but that they seemed to be themselves veritable gcds. Men watched the movements of those divine beings even as children in Catholic churches watch the entrances and the exits of mitred bishops, robed priests, and surpliced acolytes, recognising in each a solemn religious meaning, though not knowing what their movements and ministrations may precisely signify. Tliey had no need in those days, so far as worship was concerned, of " temples made with hands," for the arched dome of heaven, alike by day and by night, was their temple, the sun and moon, the stars and planets, were their gods. But that they might note with due pre- cision the positions and movements of these ruling powers, they required earthly structures, and those structures, thus raised to watch the movements of their gods, became sacred : their pyramids and towers were like lady-chapels within a vast cathedral, their gnomons and obelisks were as altars or other essential adjuncts of their Sabaistic temples. Turn without passing through all the intermediate stages of men's progress, at once from the simple adoration of those older times, when men prostrated themselves bodily before the orbs of heaven, to the teachings of modern science, and it might seem that men had become on the one hand altogether wiser, on the other altogether less reverent. Think what the earth is to us now in its lessons of a vast antiquity of ever-changing aspect, of ever-varying forms of life 1 Consider the infinite depth and solemnity of the tones in which the heavenly orbs speak to man to-day ! We are then disposed to smile at the simple, the almost touching ignorance of mankind, during the childhood of their race. Yet, even as the grown man looks back with something of regret upon the fond hopes of youth, and even on the fooUsh fancies of boyhood and the illusions of infancy, so might the profoundest student of to-day be led to envy former ages their simpler faith, did he not recognise that the univer.se as we see it today, rightly understood, j)resents a grander and more enduring temple for men, a more wonderful powei- for their worship than the men of old times could even have imagined. Consider the steps by which men passed from their former contented ignorance to their present growing, but ever un- satisfied, thirst for knowledge — noting at every step how the unknown and unexplained seemed ever to be the place of Deity, but that while the unknown was ever passing into the domain of the known and the unexi)lained into the domain of the understood, men's recognition of the immen- sity of the unknowable, the infinity of the inexplicable, has been ever growini; clearer and more defined — so that whereas once men saw a temple in the skies and deities in the orbs of heaven, the universe itself is now recogniseil as the temple of the godhead, the power working in and through all things as Almighty Omnipresent — aye, and Ever-manifest — Deity. First came the recognition that our earth is a globe, and the measurement of that globe's size. The n.ations of old times had doubtless come to recognise the earth as occupying a large space, for they knew that long distances separated Babylon from Egypt, and either from India, and fo forth. None of the earlier nations can have doubted that the earth's surface must be measured by millions of square miles, or the equivalent of such spaces in their modes of measurement. Still, the surfivce they had imagined as belonging to the earth was almost as nothing compared with the 200 millions of square miles which thej' recognised as forming the surface of the entire globe, even when they had measured but small arcs of it, and surveyed but a minute portion even of the regions known to them. Then the recognition of the fact that this globe-shaped home of the human race is suspended, as it were, in mid space, even if it be considered (as by them it was considered) to be the fixed centre of the universe, must have had an impressive effect on the minds of thinking men. Still all this was as nothing compared with the signifi- cance of the demonstration by Copernicus that the earth and the planets form one family, the sun being the centre about which they all travel. Because, so soon as this had been 98 ♦ KNOWLEDGE ♦ [March 1, 1888. accomplished, it became possible to foi-m a clear idea of the relative distances and even some idea of the actual distances of the other planets, and thus to form adequate ideas of the relative importance of those orbs as compared among them- selves, and even as compared with the eai'th. The addition to the universe of five other worlds, probably at least as large (on the average) as the earth, was assui'edly a most striking achievement. No wonder if the more narrow- minded among religionists, unable to reconcile such a dis- covery with the limited ideas they had formed of the might and wisdom of the Deity, shuddered with horror at the daring of the Copernicans in imagining (nay, in even venturing to prove), that there may be other worlds than ours. Even this, however, was in turn but nothing when com- pared with the discovery of the real meaning of the stars, following almost immediately on the recognition of the real nature of the planets. Tycho Brahe, who was moved with something like indignation against the doctrines of Coper- nicus, pointed out at once that if they were true every star must be an orb of enormous size and splendour, perhaps comparable even with the sun, which he regarded as preposterous. For, said he, our earth could not circuit in this immense orbit which the fond Copernicans as- sign to her, without causing the constellations to change entirely in aspect in the course of each year. In autumn or winter, for instance, we look at the constellation Orion from a position many millions of miles away from that which we occupy when we look at that constellation in spring. Hence the star groupings would present an entirely altered appear- ance, unless we are to imagine that such a distance as 100,000,000 of miles (the real distance is 18(5,000,000 of miles, but Tycho Brahe did not know that) counts for nothing as compared with the distances of the stars. But if so, if they really lie at distances which must be measured by thousands of millions of miles, we need only remember that our sun removed to such distances would look no larger than a star, to see that we must regard the stars, manifestly self-luminous as they are, as veritable suns, if this pernicious Copernican theory is admitted. When Kepler and Newton had established the Copernican theory on altogether irrefragable evidence, and when the telescope enabled men to measure the planets, still grander ideas about the universe began to force their way into men's minds. It was seen that Jupiter and Saturn are very much larger than the earth, and are the centres of systems of subordinate worlds. With increasing accuracy in the estimates of the sun's distance, it was seen that all the planets are farther off, and therefore larger than had been supposed. It became, in fine, certain that the earth is not the chief member of the family of worlds attending ujion the sun. But this was nothing compared with the amazing sig- nificance of the self-same telescopic teachings in regard to the stars. Not only did every increase in the estimate of the sun's distance increase in corresponding degree men's estimate of the stars' distances, but every increase in the power of estimating position made clearer and clearer the apparent fixity of the stars, and therefore threw them, as it were, farther and farther back into the abysses of space. It had been wonderful enough that the eye could detect no relative displacements among the stars as the earth circled in her wide orbit around the sun. But it presently became clear that, even with the immense increase in the power of determining positions which the telescope gave to astrono- mers, no sign of change could be detected during the year in the position of any star. Bradley attacked the problem, but though he worked so well that he was able to detect the annual change due to the aberration of light and the nutation (or nodding motion) of the earth's axis, he dis- covered no annual displacement. The best astronomers in Great Britain and on the Continent attempted the task and failed. At length astronomers gave up hope, beginning to regard the stars as, all and severally, too far removed to afford appreciable evidence of displacement as the earth revolved in her wide orbit around the sun. But just when success was despaired of, a double success was secured. Henderson, at the Cape of Good Hope, recognised the measurable annual displacement of the bright star Alpha Centauri ; while Bessel, at Konigsberg, recog- nised a smaller yet measurable displacement of the faint star (barely visible to the naked eye) numbered 61 in the constellation of the Swan. (Bessel had chosen this faint star for observation because it is moving much more rapidly on the star sphere than its fellows, as if it were rela- tively near the earth, so that its motion, though not really greater than that of other stars, appeared greater through the effects of proximit}'.) But when at last the problem had been mastered, when for the first time the actual dis- tances separating us from the stars, and the stars from each other, came to be recognised, how tremendous those dis- tances were found to be ! The nearest of all the stars in the heavens lies twenty millions of millions of miles from us, in such sort that light speeding with a velocity of 187,000 miles in a second takes more than three years in coming to us from that star. Our sun removed to the same distance would appear but as a star — nay, he would be a very much smaller star, in appearance, than that nearest of all our neighbouring suns. But in the meantime, while one set of astronomical researches was showing astronomers the immensity of stellar distances and the sunlike character of every star, another set of researches had shown and was showing the vastness of the numbers of the suns within our galaxy. The thousands of suns visible to the naked eye had increased to hundreds of thousands in the days even of Galileo. Another century had shown astronomers that the stars within telescopic range must be counted by millions. Sir William Herschel's gauges of the star depths had shown that our estimate of the numbers of the stars must run into tens and even hundreds of millions. And to-day, it is well known that if the most powerful of the telescopes made by man could be used in surveying every portion of the heavens, the total number of stars which would be brought into view would far exceed one thousand millions. The increase with each increase of telescopic power has, more- over, taught the lesson that we can in no sense limit our estimate of the number of stars by the number which even our most powerful telescopes would show. If we could double the space-penetrating power of our telescopes, we should probably much more than double, we should increase manifold, the number of stars — that is, of suns — which would be brought within our ken. Not thousands of millions, but probably millions of millions of suns exist within the limits of the sidereal system. Bather — I ought to say — they exist within the limits of our sidereal system, for doubtless this system is no more to be regarded as single within the viniverse than our solar system is unique within the star depths. Every star tells us of a sun. and probably of a solar system, in such sort that we must recognise thousands of milHons of solar systems in the galaxy. May we not fairly assume, then, that in like manner our sidereal system is repeated millions of millions of times within some systena of a higher order. That system may be in turn repeated many millions of times within a system of a higher order. And so on, to higher, and higher orders, absolutely without end. Recognising this as the teaching of the astronomy of to- March 1, 1888.] KNOWLKDGE ♦ 99 day, and noting how great to us appears tlie earth itself, though she is but the first step in an evergrowing series, each successive term of which enormously surpasses the preceding, we cannot but perceive that it is infinity, not mere vastness with which we have to deal : " End is there none to the universe of God : lo, also, there is no be- ginning." SHAKESPEARE SELF-DRAWN. By Besvolio. I.— "TITUS ANDRONICUS." lEAST attractive of all the Shakespearean plays, in certain passages absolutely repul- sive, " Titus Andronicus '' is yet in many respects most interesting to the Shake- spearean student. When as yet little had been done towards classifying Shakespeare's plays in the probable order of their pro- duction, it was natural that this play should simply be rejected as not Shakespeare's work at all, save, perhaps, that a passage here or there might be regarded as thrown in by his master hand. It was obvious that the author of " Macbeth," " Othello," and " King Lear," whose method of tr&iting tragic horrors is so powerful, ctin- not have been also the author of the crude horrors, the repulsive yet weak and almost ludicrous sensationalism of " Titus Andronicus." And that remains obvious still. But Shakespeare in 1.587-89 was not Shakespeare the author of " Hamlet," " Julius Cresar," " Macbeth," and " Coriolanus." He was a young man, country bred, impei-fectly educated, associated with dramatists and actors of greater knowledge and experience, one in whom the audacity of youthful genius was tempered indeed, but not by his own judgment but by deference to the judgment of men really his in- feriors, whom he then naturally regardeel as his superiors. Moreover, it must be remembered, that even if Shakespeare himself, as a very young man (from twenty-three to twenty-five) had been able, against the judgment of experi- enced actors, to decide that plays like Kyd's " Spanish Tragedy," and the other bloody tragedies which had been in vogue for years before he came to London, were coarse and repulsive, he wovdd still have been disposed to believe that such tragedies, nevertheless, must be purveyed for audiences whose tastes probably were as coarse as those of the modern audiences at the Victoria Theatre and (till lately) of the Surrey Theatre. It is certain that Shakespeare, even far later in his career as a dramatist, wrote for the groundlings as well as for the more cultured among his audiences ; it is certain aLso, that, until late in that career, he regarded play-writing as belonging to an inferior order of literjiry work. We can hardly suppose that Shakespeare failed to recognise later the value of his plays as poetrj' ; but he had probaV)ly written a dozen plays before the time when he would have set any of them on the same level with his " Lucrece," or even with his " Venus and Adonis." Thus, in considering Shakespeare's part in the production of " Titus Andronicus," the earliest of all his plays, we are free to admit much which we should at once reject if the plaj' belonged to a later date ; while, in the case of offen- sive, even repulsive passages, which we may thus either attribute to Shakespeare's pen or regaid as having passed his scrutiny uncondemned, we may recognise rather the modesty of his youthful mind, accepting what his elders approved, and even writing in the style which seemed to them good, than absolutely coarse tastes even at the time when he was little more than a half-educated country lad, Shakespeare's connection with " Titus Andronicus " is much more clearly made out than his authorship of many of the plajs which bear his name. The play is one of six tragedies mentioned by Meres (Palladis Tamia, Wit's Treasury) in L598, .as proving Shakespeare's excellence ; and it must be remembered that the association of Shakespeare's name with a plaj- in the days when as 3-et his fame was not established on the firm footing which it afterwards had, is much more decisive of the question of authorshi]j than similar evidence would be in after years when Shakespeare was the acknowledged leader among the dramatists of his age. We can understand how Fletcher's name came to be dropped from the title-leaf of " Henry VIII.," of which Fletcher certainly wrote more than half; but had not Shakespeare written much more than the half of " Titus An- dronicus," his name would certainh' not have been associated with it when it appeared (perhaps 1.589) or for many years after. Even if we had to accept the whole play as Shakespeare's (which, fortunately, is forbidden by external and internal evidence alike) we should find scarcjly a gi'eater contrast between "Titus Andronicus" and "King Lear" (the later tr.agedy to which it is nearest akin), than there is between " Love's Labour's Lost," the earliest comedy, and " Twelfth Night," Shakespeare's finished work. As much of the falsely heroic as there is in '' Titus Andronicus," so much at least is there of false humour in " Love's Labour's Lost." It has been remarked by a laborious Shakesjiearean student respecting " Titus Andronicus," that it would be unsafe to attempt to point out certain passages as Shake- speare's, because we do not know the distinguishing features of his style when be first began to write for the stage. To my mind this remark suggests small critical acumen. It would be unsafe to point out certain pas.sages as not Shake- speare's, and for the reason indicated, that we do not know what characteristics distinguished the Shakespeare of the time when "Titus Andronicus" appeared. But this need bj- no means prevent us from recognising passages as undoubtedly Shakespearean which present characteristics such as his work, and his alone, has displayed. Viewing " Titus Andronicus " thus, the student who has entered into Shakespeare's mind and character, and has learned to know the ring of his music, will, I believe, recog- nise much more of " Titus Andronicus " as certainly Shake- speare's than critics of the Furnivall school imagine ; while he will be disposed to reject as not Shakespearean much less than he would were the play to be dealt with as belonging to the prime of Shakespeare's dramatic career. Nearly the whole of the fii'st scene Ls Shakespearean in tone. In particular the description by INIarcus Andronicus of his brother's services to Rome, all but the first few lines is manifestly from the same hand, as yet, however, unpractised, which later wrote Coriolanus's speech, be- ginning " Hail, lords 1 I am returned your soldier." Compare with this also the speech of Titus himself in scene ii. : — Hail Rome, victorious in thy monrning weeds I Lo, as the bark, that hath discharger! her fraught. Returns with precious lading to the bay From whence at tirst she weighed her anchorage, Cometh Andronicus, bound with laurel boughs, To re-salute his country with his tears. If in this speech and much which follows in scene ii. we recognise the " 'prentis han'," that hand is still manifestly the hand of Shake.speare. Even in the schoolboy Latin introduced here and elsewhere throughout this crudely con- cocted tragedy, we may find something Shakespearean, ay, and something throwing light on Shakespeare's character ia 100 ♦ KNOWLEDGK ♦ [March 1, 1888. boyhood and jouth. We have a touch also of Shakespeare's own self in the lines : — Wilt thou draw near the nature of the gods ? Draw near them, then, in being merciful ; Kweet mercy is nobility's true badge. The touch is all the truer that it is dramatically inappro- priate. When Portia speaks of mercy as " an attribute to God himself," as " mightiest in the mighty," and as befitting " the throned monarch better than his crown," we feel that it is Portia who speaks ; and, though we need not there- fore regard the passage as wholly without significance respecting Shakespeare's own nature, we have yet in the dramatic fitness of the sentiments a sufBcient explanation independently of Shakespeare's personal character. But when Tamora speaks so nobly of mercy, ignoble of nature, and cruel as she was, our sense of the dramatic impropriety of the sentiment in her mouth enables us the more confidently to regard that sentiment as coming from Shakespeare's own heart. Tamora might have begged abjectly for mercy; but she could no more have pleaded with such earnestness of reasoning than Portia, most intel- lectually gifted of all Shakespeare's women, coidd have pleaded with Shy lock to be merciful only out of pity. Later in scene ii. we come in all probability on the materia] of the original play, which Shakespeare can only have left in despite of his better judgment The murder of Mutius by Titus would be repulsive were not the passage made utterly ridiculous by the coolness with which Titus, Lucius, Martins, and the rest treat the whole affair. If Shakespeare kept this play, as it remained after his re- writing and revision, and later looked it over, how his developed dramatic taste must have been at once offended and amused by the remark of Lucius as he enters on hearing his brother's dying cry : — My lord, you are unjust ; and, more than so, In wrongful quarrel you have slain your son 1 * In the beginning of act 2 four lines occur which no one but Shakespeare could have written — at least, as lines in a play dating so far back as 1589. I refer to the description of sunrise : — As when the golden sun salutes the morn And having gilt the ocean with his beams Gallops the zodiac in his glistering coach. And overlooks the highest-peering hills. I do not remember, by the way, the use of the word " peer " in the sense here given to it by any of Shakespeare's dramatic contemporaries. Shakespeare himself uses it in a kindred sense in " Henry V.," where Henry, speaking of the French " horsemen on yon hill," says : — . . . yet a many of your horsemen peer. Further on in act 2, in the passage which introduces the repulsive lusts of Demetrius and Chiron, we find lines which are remarkable as being the only passage repeated (in effect) thrice over in Shakespeare's works. She is a woman, says Demetrius of Lavinia : — She is a woman, therefore may be woo'd ; She is a woman, therefore may be won ; She Is Lavinia, therefore must be lov'd. In the first part of " Henry VI.," in a scene unmistakably from Shakespeare's hand, Suffolk says of Margaret: — She's beautiful, and therefore to be woo'd ; She is a woman, therefore to be won. * Yet even this, regarded as due to mere carelessness, is matched by Imogen's coolness when Guiderius, whom she had loved as a brother (not knowing that he actually was her brother) has been condemned to death. " Thou art dead," says Cymbeline to Guiderius ; and Imogen is only moved to remark that she has mis- taken the man whom Guiderius had killed for her husband. — Oymheline, last scene. And if any doubt could remain that these are Shakespeare's words, it is removed when we note that his 41st sonnet has the lines : — Beauteous thou art, therefore to be assail'd ; tientle thou art, and therefore to be won. The thought here conveyed, and the form in which the thought is presented, must have had a singular charm for Shakespeare, that he (who so seldom repeats himself) thus frequently repeats this idea in almost the same words. I know of no passage more truly Shakespearean in "Titus Andronicus" than the forest scene, as described (iuapjiropriately enough) by Tamora, that " unhallowed dam," addre.ssing the ravenous tiger and accursed devil," Aaron the Moor : — Jly lovely Aaron, wherefore look'st thou sad. When everything doth make a gleeful boast / The birds chant melody on every bush ; The snake lies rolled * in the cheerful sun ; The green leaves quiver with the cooling wind. And make a checker'd shadow on the ground ; Under their sweet shade, Aaron, let us sit, And whilst the babbling echo mocks the hovmds, Keplying shrilly to the well-tun'd horns. As if a double hunt were heard at once. Let us sit down and mark their yelping noise. And after conflict, such as was suppos'd The wandering prince and Dido once enjoy'd. When with a happy storm they were surpris'd, And curtain'd with a counsel-keeping cave. We may, each wreathed in the other's arms, Our pastimes done, possess a golden slumber ; While hounds, anrl horns, and sweet melodious bird.^, Be unto us, as is a nurse's song Of lullaby to bring her babe asleeji. One might imagine this addressed by Venus to Adonis ; one might imagine it part of a poem written by Shakespeare on the theme of his " Venus and Adonis," but in another strain ; one may even imagine in it a picture of fair but forward Anne Hathaway pleading with her youthful love : but while one can see no fitness in words such as these placed in the mouth of the fiendish Tamora, one cannot imagine that any penned them but Shakespeare. The style is his, the thoughts are his, the words are his ; but, beyond and above all, the music is his, and none other's. Repulsive as is the rest of this scene, no one, I think, who compares the appeal of Lucretia to Tarquin in Shakespeare's " Lucrece " witli the appeal of Lavinia to Tamora and her sons, can doubt that the former is not more certainly Shake- speare's work than the latter. The scene is one on which no reader cares to dwell, even to note what is beautiful amid so much that is horrible, Yet w-hat could be more pathetic than Lavinia's appeal 1 — Some say that ravens foster forlorn children, Tlie whilst their own birds famish in their nests : O, be to me, though thy hard heart say no, Nothing so kind, but something pitiful. Sciittered throughout " Titus Andronicus " we find many expressions and tones characteristically Shakespearean. Compare, for instance — Martins. To prove thou hast a true-divining heart, with JiiVuH. Oh God ! I have an ill-divining soul ; and Demetrius. I would we had a thousand Roman dames At such a bay, with the lines — Ah ! that I had my lady at this bay,t To kiss and clip me till I run away, * Probably a misprint for " coiled," a word which might be so wriiten as to be mistaken for " rolled." t The word " bay " is here used in the hunter's sense, as again in Titus's speech at the beginning of scene 2, act ii., " Uncouple March 1, 1888.] ♦ > KNOWLEDGE ♦ 101 (in the fourth of the poems — some undoubtedly not by Shakespeare, but this one certainly from his pen — included under the strange heading " The Passionate Pilgrim "l ; and again — Aarun, Here's a young lad, fram'd of another leer, with CeHa's, " he hath a Rosalind of a better leer than you." "Titus Androniciis " is well worth .studying for the many truly Shakespe;irean Ijeauties it contains, if only one can overcome the sense of disgust which several scenes in the play tend to inspire. Once recognised as in the main Shakespeare's work, it is suggestive as to his character in youth, and as to the development of his poetic and dramatic instincts. Apart from direct suggestions of this sort, there is something singularly suggestive of Shakespeare's modesty at this part of his career, in his adhesion for the time to the older tragic style, which even then he must have recognised as distasteful, if not repulsive. HAVE GHOSTS BEEN SEEN? EW subjects tax more stringently what may be called the scientific conscience than the matter of apparitions. The student of science recognises two clear duties in all scientific inquiries. In the first place, he must strive to see things as they are ; and in the second, he must speak of them as he sees them. Against strict obedience to the first duty prejudices of all sorts, shapes, and sizes often oppose themselves ; but when he has resisted the temptations thus soliciting him to careless or sceptical or unfair inquii'V, he is often still harder beset by the temptation to conceal views that he thinks may injure him either among fellow-workers in science or in the lay world. In regard to ghosts and goblins, science has travelled along smoothly enough so long as apparitions of particular classes have been in question. The whole subject of hallu- cinations has been explored by science so thoroughly that no one now is perplexed by stories of visions such as those that troubled Nicolai, Jilake the painter, Mrs. A. (of Brewster's "Natural Magic"), and a number of other persons. The vision in such cases is but " the blot upon the brain that will show itself without," and science is " not to be over- awed by what it cannot but know is a juggle born of the brain." Nor has science been much concerned about those old- fashioned ghost stories, telling how sheeted foims and unearthly sounds have affrighted sensitive folk under con- ditions suitably suggestive. We have learned to understand how readily under such conditions as the gloom of night, chilly air (starting shivers and tremors, which of themselves suggest unearthly feelings), and so forth, the mind will unconsciously form false images out of dimly seen objects, or transform unexplained noises into sounds significant of horror. A waving cloth becomes a beckoning sheet-clad ghost; the creaking of a door sounds like the shriek or moan of some one in agony. Out in the open air, in gloomy woods, or valleys half hid in mist, sights and .sounds that by day would not be noticed are by the active mind changed to awful appearances or terrible noises. To this day, for instance, in parts of England, the noises here and let us make a bay." Shakespeare's love of hunting comes outmost markedly in his earlier plays and poems, as in "Titus Andronicus," •' Love's Labour's Lost," " Midsummer Night's Dream," and " Venus and Adonis." * From the Cosmojiolitan, a leading American monthly magazine. made at night by migrating birds are regarded as the bark- ing and yelping of the Gabriel hounds (" CJabriel " is itself a suggestive transformation from " gabble "), which in recent times — I mean somewhere within the last ten or twelve centuries — have been found by the foolish country folk to be the souls of unbaptised children ; while (since the hounds have never done any harm directly) it has been held reason- able to regard them as indicating some approaching trouble for those who may hear them. There has not only been no trouble in interpreting the ghosts and goblins of this type, but no difficulty has arisen in consequence of visions and voices which have seemed to simulate the appearance or tones of the dead. Here the argument from coincidence, rather too freely urged aljout apparitions in general, may be safely used. Undoubtedly fancies of the kind described are so numerous, that we may f^iirly expect some among them to correspond (in the manner characteristic of ghost stories) with the supposed return of the spirit of the dead to his earthh' home. Especially is this the case when we remember how such f^incies are in- fluenced by predominant ideas, and how, therefore, a person whose mind is full of the thought of some dear lost one would be more apt to form a mental picture of the dead friend or relative than of some form or face entirely un- familiar. Even where several persons have seen, or seemed to see, one and the same vision, science is at no loss to explain the illusion, because it is well known that the thotight of one mind is suggested readily in such cases to another mind liable to similar impressions. Consider, for instance, the well-known story of the widower, who thought he saw in the dusk of evening the form of his late wife (only recently deceased) sitting in a garden chair ; he called one of his daughters, and asked in awe-struck tones whom she saw sitting there 1 And the daughter saw her mother. Another daughter being called was similarly impressed with the thought that her mother sat in the chair which in life she had been wont to occupy ; but when, summoning up his resolution, he went forth into the garden to speak to bis " late departed saint," lo ! he found not her in her habit as she lived, but her garden dress, which a maid had placed over the seat. It is obvious that the thoughts filling the mind of the father transformed a dress into an apparition, and it is probable that this thought was conveyed from his mind to his daughters', rather than suggested independently to them. In any case, there was no real apparition. It is when we turn to visions of living persons, or to thoughts and suggestions relating to living persons, at a dis- tance from the person affected by the vision or impression, that we find evidence most difficult to deal with, and the results not only difticult to explain, but not altogether satis- factory for discussion, because the number of those who welcome the discussion of all such matters, either with credulity or with ridicule, enormously exceeds the number of the more thoughtful. The following is one of the best authenticated of a class of stories whose name is now becoming legion : — • In September 18.57 Captain W., of the Gth Dragoon Guards, left England to join his regiment in India, leaving his wife at Cambridge. On the night between November 14 and 1.1, 18.")7, she dreamed that she saw her hu.sband looking very ill, and she thereupon woke in great agitation. When she looked up she saw the same figure standing by her bed- side. He ajipeared in uniform, and as if suffering intense pain. He then gradually faded from her view. At first Mrs. W. supposed she must still be asleep ; but rubbing her eyes and listening to the breathing of a cliild beside her, she convinced herself that what she had seen was no dream. In December 1857 a telegram from the seat of war 102 KNOWLEDGE ♦ [March 1, 1888. appeared in the morning papers, stating that Captain W. had been killed before Lucknow on the Ji/teenth of November. The family solicitor applied for further infor- mation as to the date of Captain W.'s death, which Mrs. W. felt sure must have taken place on the fourteenth, and not on the fifteenth. But the date given in the telegram was confirmed at the War Office. At this time a singular cir- cumstance came to light. The solicitor chanced to mention the case to a lady, a friend of his, who, according to his account, had a tendency to see visions. Turning to her husband, she said, " That must have been the same appari- tion I i^aw on the evening when we were speaking about India." They were able to fix the date, by means of a receipt for an amount paid that day, as the fourteenth of November. The solicitor on this applied to the War Office again, saying that the friends of Captain W. were persuaded there must be some mistake about the date. The officials stated, however, that there could be no mistake, since the death was referred to in two despatches from Sir Colin Campbell, who in both cases gave the date as the fifteenth. Tn March 1858 a letter arrived from a brother-officer, giving an account of Captain W.'s death. This officer, who had been riding beside Captain W. when he was killed, stated that death occurred ou ihe fourteenth of November. Finally — though whether on the strength of this officer's evidence or through faith in the apparition's truth to time — the date was altered to the fourteenth. It seems never to have occurred to any one to consider the difference between Indian and Englisli time. If the time of Captain W.'s death really coincided, as Mrs. W. then and thereafter firmly believed, with the time of her dream, then, imless she went to bed unusu.ally early, he was killed on November 15, Indian time. Suppose, for instance, she had her dream at ten o'clock on the night of November 14, then at that moment it was twenty-four minutes past three on the morning of November 15 at Lucknow. Supposing it was later, as the account suggests, then we may well suppose that daylight had already broken on the morning of the 15th at Lucknow, at the hour when Mrs. W. had her midnight dream at Cambridge and her husband met with his death. One other narrative, before we consider the philosophical aspect of the multitudinous stories of this kind which are vouched for on good authority : and be it remembered, in passing, such stories as these can be unmistnkably confirmed, and have frequently been so confirmed, independently of the veracity of the persons who assert that they saw the vision or experienced the impression considered. The following story is related almost in the words of the Bishop of Carlisle, better known in former days at Cambridge as Dr. Harvey Goodwin, the eminent mathematician : — A Cambridge student had ari-anged, some years ago, with a fellow-student tliat they should meet together at Cam- bridge for the purpose of reading. A short time before going up to Cambridge to keep his appointment, one of them — from whom Dr. Goodwin had the story — was in the south of England. Waking in the night, he saw, as he imagined, his friend sitting at the foot of his bed. He was surprised by the sight, the more so as his friend seemed to be dripping with water. He spoke, but the apparition shook its head, and presently disappeared. But the vision reappeared a few minutes after. Information was soon received that at about the time when the apparition was seen by the young student his friend had been drowned while bathing. It will be remembered that Lord Brougham had an experience very similar to the one just related ; and there are other cases of the same kind — that is, cases in which an apparition of a distant friend, at or near the hour of death, has been seen by one to whom a promise had been made, the fulfilment of which had been prevented by death. It must be admitted that, as the Bishop of Carlisle has said, the evidence in regard to apparitions of this sort is such as would be regarded as decisive in any matter of independent scientific research. The a jMsterio7-i eyidence, in fact, considered alone, would be regarded as conclusive : it is only because of the strong a priori unlikelihood, amounting with many to the impossibility that such in- fluences from a distance can be exerted under any conditions, that the student of science finds the force of the evidence weakening, not indeed absolutely but relatively, until he is almost ready to reject it Sfcte h 'a "■•n0/es ; German ja. In Arabic i>/ answers to our i/es or yea when followed by an oath. Although the origin of the affirmative particle is not satisfactorily discovered, that of the negative is quite clear. When the infant is not hungry, or does not wish to take anything into its mouth, it moves its head from side to side to avoid the object offered, at the same time closing its lips tightly, and when the voice is exerted through the closed lips the sound m or /i is given out.* This accounts for the widespread use of these sounds to express the negative, as in the Greek ;)((', Latin ne, whence nego, French nier, Illyrian nekaii, On. neila, vita, to sny iie, " deny, refuse." It will be remembered that the expression of the negative is usually accompanied by a lateral shake of the head. The simplest form of the negative in Latin and Teutonic languages is ne, whence iwn from ne-unum, old form nenu, in the same way as our none from ne one or no one, German nein. from ne-ein, and later English no. From it the Romans got the compounds ne-quis, ne-cuter {neuter), nuUiis, the substantive ne-inon-, German, nie-mand, the adverbs nunqiiain, n\isquam, and the verbs ne-queo, ne-scio, ne- uolo, afterwards nolo. In Anglo-Saxon we have nis, " is not," niU, " was not," ic ndt, " I wot not," >c nah, " " I own not," with ic nali, "I own;" ic nabbe, " I have not," if nelle, '"I will not," with a perfect noMe, similar to our expression ii:illy-niUii, "whether he will or no." Jamieson gives the old Scotch nam, " am not," 7wr, " were not," nat, " wot not," as well as nold. The very word not itself is a similar compound of Gothic ni-raiht, Anglo-Saxon naiviht, German nicht, and our nawjht. Chaucer says, " They knew him navght." Old Scotch has noct, E.. Brunne noght, and Robert of Gloucester 7iogt. Lat. non is reduplicative, and has a stronger sense than ne, as in the repetitive French ex- pressions ne . . . pas, ne . . . point, ne . . . rien. Ma. is one of the forms of the negative in Semitic languages ; in Hebrew it is used as an interrogative, and in Arabic as the negative of the definite or absolute present, and of the perfect not. In Arabic there is also an interrogative form, amd (used in the same way as the Latin nonnc), with dialectic varieties, ama, liamd, liama, &c. ; in Hebrew there is also a form with the interrogative he, followed by xm. Another form of the negative is la in Aiabic, lb and al in Hebrew, probably a derivative from the older ni form. Both are combined in the Arabic lam, negative of the per- fect lamma, '' not yet" ; Heb. lamma, " why? " In oaths the Hebrew im is a negative particle, but it commonly means if. Probably the original meaning of im * See "Thought and Language," x. Knowledge, vol. vii., pp. 474-47.5. was " is it not ? " A in in Hebrew ^ nothing, or 7iot ; as in a in lee, I have not, is also used in an interrogative sense, '• where," Arab, ai/in. Indeed, in most languages the negative readily passes into the interrogative, as, " Is it not so t " In Chinese the negative adverbs are : 7nii, " to be without "^no or not, the opposite of yii', " to have ":=" yes there is"; pil, not, the most common negative, which has no other use ;_/?, " not to be — false," it is not opposed to sM, " to be" = ''yesit is"; wn, "not to have " = '• without " = m«- i/iii, also much used (the Canton dialect expresses the nega- tive of possession by mo) ; mo, •' not, do not," a synonym of p)'', " not," and m in the Canton dialect, which is the equivalent of the mo and pn of the books. Here pa and /(' have doubtless their origin in the pooh, faugh sound with which we reject a nauseous morsel, and similarly an unpleasant proposition, while the w in wil is most likely the phonetic representative of the earlier form with in. With regard to the interrogative use of the negative as in Aryan and Semitic languages, in Chinese mo is a final interrogative in the Mandarin, and n'l in the Canton dialect. In Chinese, as in several other languages, two negatives make an affirmative : thus, mo-fl, in ngo mo ft shivo-]nixing pu ch'tng, "I surely do not lie at all," and uutf'i, and /7 with pa ai'e similarly used, as/7 fil pit. k'o, " cannot do without him." IF?? is sometimes u.sed as a pro- hibitive " Do not I " and so also is mo when it stands alone. Asironomt/ for Amateurs. Edited by John A. West- wood Oliver. With the Assistance of T. W. Backhouse, F.R.A.S. ; S. W. Burnham, M.A., F.R.A.S. ; J. Rand Caprox, F.R.A.S.; W. F. Denning, F.R.A.S.; T. Gwvn Elger, F.R.A.S. ; W. S. Franks, F.R.A.S.; J. E. Gore, M.R.I.A., F.R.A.S. ; Sir Howard Grudb, F.R.S., F.R.A.S. ; E. W. Maundee, F.R.A.S. ; and others. (London : Long- mans, Green, & Co. 1888.) — Mr. Westwood Oliver and his very able stafT of coadjutors have produced a work of endur- ing value to the astronomical student in the volume before us, of which it is not too much to say that it should be carefully studied by every incipient observer who hopes or wishes to do any work whatever of scientific value. For it is especially with such work, as contradistinguished from mere desultory stai'gazing, that this capital little book con- cerns itself; and, no matter to what special branch of astronomy the beginner proposes to devote his energies, he will here find explicit directions, from a master hand, for the most successful method of prosecuting his studies, and enriching science by the results of his personal labour. After a preliminary discourse on the leading divisions of astronomical research by the editor, we have a thoroughly practical chapter on the telesco)je and observatory by Sir Howard Grubb. Then ISIr. Maunder follows with an equally practical one on solar observation ; while it is only necessary to mention Mr. Elger's name as the author of the chapter on the moon to indicate its value and excel- lence— a remark which we may equally extend to Mr. Denning's dissertations on the planets and on meteors. The last-named gentleman also contributes a chapter on comet-seeking. The subject of double stars is admirably treated by him who is Jacile princeps as their observer and discoverer — we mean, of course, Mr. S. W. Burnham ; while equal justice is done to that of variable stars by Mr. Gore. Mr. Backhouse and Mr. Baird Gemmill treat jointly on stellar distribution; a chapter on the zodiacal light being founded on contributions by the gentleman first named and Mr. Arthur Searle. The work concludes with March 1, 1888.] ♦ KNOW^LKDGE 11^ a short account of the methods of observing the (ques- tionably astronomical) phenomenon of the aurora by Mr. J. Rand Capron. "SVe think that our mere precis of the contents of the volume whose title heads this notice will practically suffice to justify the terms of commenda- tion in which it commences. Certainly no more useful work to the beginner has yet appeared. A very careful perusal of it has failed to reveal more than three obvious errata. The iirst occurs on page 129, where it is alleged that "the solar parallax ... is now adopted at S'TS'," which is certainly not the case. The parallax adopted ia this country is SS4S", while the Belgian results make it greater still. At the time we write the American ones have not been made public. Perhaps the author was think- ing of Dr. Gill's Mauritius results, which are — Dr. Gill's and nobody else's : and of which he himself says ('' Dunecht Observatory Publications." vol. ii. p. -1-), "We do not attach very much importance to the value of the parallax deduced." The second mistake appears on page 1.30, where it is alleged of Venus, in and close to inferior conjunction, that " the interior region of the disc is seen perceptibly lighter than the dark background of the sky on which it is projected." Practical observers of repute have seen it darker than the light background of the sky on numerous occasions, so that the statement as it stands is far too unqualified. The third error we have noted is in the engi-aving of the ••Aurora theodolite" on page 3li, where that instrument is represented with an object-glass which has, in reality, no existence. Capital: a Critical Analysis of Capitalist i'roduction. By Karl Marx. Translated by Samuel Moore and Edward Avelisg, and edited by Frederick Excels. (London: Swan Sonnenschein, Lowrey it Co. 1887.) — • "The common-sense reader, unfamiliar with the rudiments of political economy, will rise from the perusal of this com- bination of virulent declamation and pseudo-scientific exposition with a feeling akin to that experienced by the incipient logician when he makes his firat acquaintance with the old puzzle of Achilles and the Tortoise. He will find a good dei^l that appears to him at fii-st sight in- expugnable in the shape of sequent argument ; but under- lying which he feels intuitively there is some stupendous fallacy. It is only upon re-reading Herr Marx's two volumes that he will thoroughly realise how the dominant TDotive of their author is an almost insane class-hatred ; and how, in his endeavour to gratify it, he is absolutely in- different whether he is dealing with fact or fiction. An extract taken absolutely at random will illustrate this. It is one that strikes our eye as we write, and occurs in the form of a footnote on page 2-50, which begins thus, " In England even now occasionally in rural districts a labourer is condemned to imprisonment for desecrating the Sabbath, by working in his front garden." If Herr JIarx does not know this to be absolutely false, his translators and editor do, and the mere retention of such an allegation in its pages shows the animus with which the work is written. It is quite true that, on rare occasions, that pest the '• common informer, " has summoned a tradesman under the very dis- creditable, but practically obsolete. Act 29 Car. II., c. 7, for doing '■ work of his ordinary calling upon the Lord's Day," and has obtained a conviction ; but this is a very difi"erent thing to that alleged by the author of the work before us. A labourer working in his own front garden is not " following his ordinary calling," and the statute does not apply to him in any way. The whole book is one sustained tii^ade against the middle-class capitalist. The mere sight of the word " bourgeois," or the idea of the social condition it implies, appears to exercise an influence on Herr Marx compared with which that of a red rag on a bull may be regarded as sedative and tranquillising. The perusal of a work like this to any one who has studied such masterly and scholarly expositions of economic science as those of Mr. Dunning McLeod, is like reading an essay b}' a boy in the Fourth Standard at a Board School, by anyone familiar with the undying work of Addison and Steele. Manual of the Sextant. By Charles \V. Thompson', F.R.G.S. (London: John Bumpus. 1887.)— Mr. Thompson's excellent manual of the sextant may be confidently recom- mended to all travellers and explorers whose outfit of instru- ments is confined to the one of which it treats, together with an artificial horizon and a chronometer. The optical principles on which its action depends are clearly explained, and this explanation is followed by a detailed description of the construction and use of the sextant as at present framed by our leading makers. Then the beginner is instructed how to use the instrument in observing altitudes and angular distances, and the methods of employing it to determine latitude, time, longitude, and the variation of the compass, and to set O'.it a meridian line, are taught in a manner so simple, that no moderately attentive reader can possibly fail to thoroughly grasp the modes of obtaining the results sought. Wisely eschewing formuhe. our author works out numerical examples of the various processes at full length ; and, at the end of his book, furnishes all the tables necessary for the reduction of the observations made. When !Mr. Thompson's volume runs into its inevitable second edition, we should recommend him to obtain and describe one of the remarkably ingenious prismatic sextants made by Pistor and ^lartins, the opticians in Bsrlin. These instruments measure angles up to 180^. And we may add in conclusion, the expression of our surprise that in a bDok in other respects so complete, no mention whatever is made of the method of determining the excentricity of the sextant — a matter of vital importance, if it is to be employed for refined work. The Brassfoiiiuler's Manual. By Walter Grah.am. Seventh Edition. (London : Crosby Lockwood, vt Son, 1887.) — When a book on a pureh' technical subject has run into its seventh edition, it may fairly be assumed to have criticised itself, and to have established its own claim to excellence. Assuredly in the present case the success achieved has been well deserved, for a more complete little manual than Mr. Graham's we have rarely come across. Invaluable to the commercial brassfounder, it will be found replete with information of use to the amateur who tries his hand at the construction or repair of optical and other scientific instruments. The workman who buys this little volume may further derive very great benefit, outside and beyond that of a merely technical character, by the careful perusal of pages 20 and 21. The Eskimo Tribes. By Dr. Henry Eixk. (Williams & Norgate.) — The principal object of the present work, the eleventh of a series on Danish investigations in Greenland, published at the cost of the State, and which its learned author has made more accessible by an English version, is to furnish an idea of the elements of the little-known Eskimo language. But for us the main interest lies in the earlier chapters, which discuss the mode of life, dwellings, religious and social arrangements of the Eskimo tribes, and especially in the first chapter, in which Dr. Eink, while expres.sing no decided opinion, collates the evidence which tends to confirm the theory that they migrated from the interior of Alaska, dispersing northwards until their final settlement in Labrador and Greenland. The subject is of importance as a con- tribution to the movements of races in prehistoric times, and to the general question of man's origin in, and migi-ation from, northerly hemispheres. As our readers 118 ♦ KNOWLEDGE ♦ [March 1, 1888. may remember, Professor Boyd Dawkins inclines to the theory that the Eskimo are the descendants of the men of the reindeer period, who retreated in a north-westerly direction, a theory based upon certain physical similarities and upon like customs. But this short notice is not the place for its discussion, and, moreover, we hope to return to the subject at a future time. Students of folk-lore and traditions are familiar with Dr. Rink's volume of Eskimo tales, and he has placed them further in hLs debt by the publication of the present treatise. Tenants of an Old Farm : Leaves from the Note-booh of a XaturaHst. By Henry McCook, D.D. With an Intro- duction by Sir John Lubbock. (Hodder & Stoughton.)— No compliment is paid to science by dressing up its facts in the guise of fiction, and the wonders of insects, especially ant-life, which are the subjects of this book, stand least of all in need of the story-teller's artifice to enhance interest in truths which are " stranger than fiction." As Dr. McCook has, however, with some hesitation as he tells us, chosen to season natural history with romantic admixture, we must be thankful that the work has fallen into hands as competent as his. The book is written in an attractive and animated style, and is amply illustrated with accurate, and often fantastic, woodcuts. 'I (Pur WBWt Column* By "Five of Clubs." A SAMPLE OF LAST CENTUUY'S WHIST. -I' l.^S'-'i3' j ^^ Australasian publishes an interesting ilhistra- "°* " "^ tion of the whist of a century ago. It remarks tliat " in 1871 Jlr. Hugh Lennon ]ii-escnte(l to the Jlelbourne Public Library a poem in heroic metre i which was published anonymously in London in 1791. Tliis bears the title of ■■ Whist, a Poem in Twelve Cantos." The author " thought iiroper to assume the character of a vain, petulant stripling, whose opinion of his own wit and abilities is so overweening that he thinks they entitle him to fall foul of everything that comes in his way." In his poem he not only embodies the accepted canons of the long whist of a century ago, but also discusses the requisites of a good player. Of these he signifies three in particular :— (1) Jlcmory, (2) judgment, C3) temper. , To the tenth canlo he prefixes the following argument : — "Temper, the third requisite at whist. Three causes of loss of temper. (1) Bad Inck, (2) cross play, (.3) a bad partner. Cards a terrible trial for the temper. Story of Smilinda and her lover Pusillo." This story is in brief that "Pusillo" was very much in love with " Smilinda." Being a very cautious " bird," however, he thought it best to make " one nice experimeat" before deraanriing the lady's hand, whereby He might the certain knowledge gain, If she her temper could at cards retain. The opportunity presents ifself when Pusillo and Smilinda are partners at whist against " cousin Booby's son, a country squire," and " Aunt Rebecca." Pusillo begins by making some deliberate mistakes which are of no great consequence. Smilinda is fuming inwatdly, but her eyes continue " to retain their placid charm." At length, in a close struggle for an all-important odd trick, Pusillo commits a gross blunder, and throws away the game. Thereupon The gentle creature could endure no more, She started up, she stamped, she raged, she swore. Proclaimed her wrongs, and threw the cards away, Nor longer in his presence deigned to stay. And thus that flame, wliich had for years endured. In one short minute was entirely cured. In the text the author describes the play of the hand in a general way ; in an appendix he gives in detail the cards which fall to the several successive tricks. The result is the earliest example of an " illustrative whist hand " with which we are acquainted. More- over, the hand is fairly well played throughout, except just at the point where Pusillo deliberately throws away the chance of wimiing the odd trick." „/D. (trumj)s).— S, 5. -"I.C.— Q, 7, 5. D.

NOTES ON THE PLAY. Trick 1. — Booby leads cor- rectly from his numerically strong suit. Trick 2. — But in preference to returning the club Rebecca ought to have led either her spade ace or her diamond eight. Also, if the club was to be re- turned at all, the seven ought to liave led, not the five. Trick 3. — Smilinda properly discards the spade two. Trick 5. — Smilinda — " Nov; with careful eye her hand surveys. And from the knave a heart unwilling plays ; A vile, unlucky lead in every view— (.\nd yet what better could the virgin do .' Her king of spades but once defended lay. And could not to the ace he left a prey ; Her trumps, the last resort, were now too few. Since one from four her former triumph drew). A vile, unlucky lead ; for full command Lay couched in ambush in Rebecca's hand." Trick 6— " And now Rebecca's queen a trick to gain Had sanguine hopes ; nor did she hope in vain. The lead should ne'er be changed without a cause, So from her hand another heart she draws." Trick 7 — Of course Smilinda ought to have played the heart ten. Trick 10— " But now the nymph no longer would delay, Though rather weak, her suit of trumps to play." Trick 11.— Here, again, Smi- linda plays the higher, instead of the lower, of two sequence cards.

(a) The object of this move is to facilitate rapid castling on the Queen's side. We have seen many fine games played in this opening where this has been done. White will subsequently be compelled to play P to Q4 to develop his game, and prevent the Black KB harassing the White K by playing to B4. Under these conditions, Black by castling QR besides bringing his K into safety for a time, brings his Rook to Qsq, thereby establishing a kind of masked battery on the Queen, which the latter is usually compelled to avoid by moving on the King's file. Black will then direct his play on the Queen's Pawn, and, under certain circumstances — for instance, to be able to play R to QS (eh), and for other combinative purposes — Black may sacrifice a piece effectively. These are some features of the game if Black castles QR, but it he fails to do so, then P to B3 becomes a loss of time, as Black will probably have to play P to KKt4 to defend his KBP, which would give White two squares, namely Q6 and KBG, where he threatens to place his Queen's Knight, which often succeeds when the defence is indifferently conducted, result- ing sometimes in the loss of the Black Queen ; this is brought about by a series of moves whereof the following are the essential ones, namely QKt to B3, P to Q4, P to Ko, Kt to K4, &c. Then, again, we have often observed that tlie Black P on B3 makes an ultimate advance of the White Q's P — if properly supported by the Kt on QB3 — all the more effective, for if then Black takes. White, amongst other things which he might do, may retake with his Knight, which then would occupy a strong and menacing position on Q.5 ; in the alternative of Black not taking the P on Q5, it leaves White the option of weakening Black's Q's si•-. But if calculations based on the known configuration and struc- ture of the mountain indicate that its mass would produce an attraction /on a body at its summit, and t" be the observed time of oscillation at the mountain's summit. Thus, if the times of oscillation t and t'' be accurately oompa'-ed, while t' is computed, we obtain the ratio of t' to t", or V,,' j^j to -./^■^ whence the ratio of / to (j' and thence to g is obtained ; and thus the mass of the earth may be compared directly with that of the mountain. Of course, though the principle of the method is thus indicated, the actual computations are by no means so simple. only consider the repulsion exerted by a mass filling B, every particle of which is to b ; supposed to repel with a force exactly equal to that with which it would in reality attr.^ct. Let us suppose our mine to be cylindrical, tig. .S, representing a section through the axis and the sbaft S coincident with the pro- longation of the axis. A pendulum is swinging at Q and another at P ill Q S produced. The shaft is supposed so narrow that we need not consider it, and, for convenience, we suppose its length equal to half the depth of the mine: — Let r = earth's radius 2 a = mine's depth (Q P) a = length of shaft (Q S) h = radius of cylinder (B P) Then the attraction at Q is equivalent to the attraction of a sphere of radius r, diminished by the attraction of the cylinder A U, that is (from the known value of the last-named attraction — = *--.f - 2 IT p |a - s/ia^ + b' + ■Jd^^n/'] .

Though it is tolerably obvious that this method of deter- mining the earth's attraction must be even less trustworthy than experiments of the Schehallien type, the method com- mended itself to the mind of Sir George (then Professor) Airy, and after two failures in the Dolcoath mines, he had the method tried in the Harton Colliery, near South Shields, where a depth of 1,260 feet was available. It is not necessary to describe the contrivances by which two pendulums were compared, one swinging at the top the other at the bottom of the mine, the pendulums being inter- changed after intervals of 10-t hours and 60 hours — that is, each working 104 hours above and below, and then each working 60 hours above and below. The work was con- ducted with great care and skill by Mr. Dunkin, of the Greenwich Observatory, to whom, however, no portion of the credit has hitherto been given in treatises on astronomy. The observations showed that at the foot of the mine either pendulum gained two seconds and a quarter per day, bhow-ing that gravity was increased by xaJ^jTy part. This result cannot be sensibly in eiTor, so carefully were Mr. Dunkin's operations conducted. But the inferred increase of density towards the earth's centre — that is, the deduced mean density of the earth — can by no means be regarded as ascertained with corresponding accuracy. We do not make an ordinary foot rule more precise for measuring purposes by careful and complicated experiments on the changes it undergoes under the varying influences of temperature, moisture, and so forth — it remains a foot-rule still, with all a foot-rule's shortcomings as a measurer. The complicated calculations and corrections effected by Mr. Dunkin did not even touch the real defects of the mine method of weighing the earth ; it remained rough and untrustworthy. A com- parison of the final i-esult with that obtained bj- experiments of the Schehallien class — which, though certainly not trust- worthj', were at least as trustworthj' as the mine experi- ments— suffices to show how little either method can be trusted. The earth's mean density, as calculated by Jlr. Airy from the Harton experiments, was 6-565 times that of water, and the results of the mountain and mine methods combined appear as follows : — • Mean DeDsity (Water"s=l).

James, from attraction of Arthur's Seat 5316 Dnnkin and Airy, from experiments in Harton Colliery 6.JGJ Mean 5-386 The mean value is probably, as we shall see, near the truth ; but as the greatest value differe from the least by 1852, or more than a third of the mean, the results — except Colonel James's — are discredited by the very circum- stance that the mean value is nearly right ; and all three attraction at Q is greater than, equal to, or less than the attraction at P. Putting (■)■) equal to zero, we get 3 ■jYa'^^b- = 3 J -f 2a or 36 a= + 9 J= = 9 J= ^ 12 o J ^- 4 a^ that is .32 a = V2h. Hence, if i, the radius of the cylindrical mine, is equal to tour- thirds its total depth, the attraction at P will be equal to that at Q. If the mine be wider, the attraction will be greater at P than acQ. All other cases may be similarly treated, though, of course, the problem will not in all cases be so simple as the above. methods are discredited, the correctness of Colonel James's result being thus shown to be merely accidental. If the length of a piece of ground had to be measured, and one workman said that measuring it in a certain way he found it to be 471 feet long, while another using a different method made it 49.5 feet long, and a third, using yet another method, found it to be 657 feet long, their employer would not regard their work or their methods as satisfactory if he presently found that a thoroughly trustworthy measurement showed the piece of gi-ound to be 550 feet long, even though that is not far from the mean of the results obtained by three unsatisfactory methods. And if, later, a fourth work- man, employing one of those methods, deduced as a result 539 feet, trust in that method would not te greatly increased. It would be felt that either the approach of the result to the truth was accidental or it was more or less consciously forced. Airy expressed the opinion that the result of the Harton Colliery experiment was comparable on at least equal terms with those obtained by other methods, though it differs by 20 per cent, from the mean of the results obtained by all methods, and the results presently to be considered do" not differ by more than 2 per cent, from their mem value, nor by 4 per cent, from the general mean. I prefer the opinion of Sir Edmund Beckett (now Lord Grimthorpe), that the result of the Harton Colliery experiments " cannot be accepted," and is " not to be compared in value " with those obtained by the Cavendish experiment. The ingenious Michell, to whom science owes the first satisfectorv' reasoning about the architecture of the sidereal heavens, devised the method of weighing the earth which is commonly named after the eminent chemist Cavendish, who first successfully applied it. ( To he concluded.) COAL. By W. Mattieu Williams. -MINERS' LAMPS AND COLLIERY EXPLOSIONS. APPILY for themselves, few or none of my r&aders have any practical acquaintance with absolute darkness. "With the excep- tion of a skilfully devised horror — the dark punishment cell in some of our prisons — scarcely any place can be found above ground where such darkness prevails. But in a coal-pit, without lamp, it exists in perfection. The lighting of a coal-mine is a serious problem, not because illuminating gas is dear, but for the opposite reason. Lead, copper, and other mines in which metals and their ores are worked, are lighted by the primitive device of wearing a candle in the front of one's hat while travelling down the shaft or along the working.*, and sticking it in a miner's candlestick, a lump of clay, which is superior to ordinary candlesticks, inasmuch as it may rest on the ground or con- stitute its own bracket by being dabbed against a wall, or take any other position required. Primitive oil-lamps of pattern closely resembling those found so abundantly in Pompeii, or metal lamps with a hook at one side for attachment to the hat or hanging to ledges, are used, and others with a spike below for simdar purpose; but the candle and lump of clay is the general favourite. Paraffin lamps have been lately introduced. Candles and such lamps may be used in some coal-mines, but these are exceptional, the majority of coal-mines beinw " fiery." This means that hydrocarbon gas, which has been 126 ♦ KNOW^LEDGE ♦ [April 2, 1888. occlufled or imprisoned for ages, starts forth on breaking down the coal, and may acoumuUxte to a dangerous amount. So far as I have been able to learn, no coal-mine is free from " fire-damp ; " in those that are worked with naked lights, " blowers " of gas may occasionally be heard, and seen when the men apply their candles to them, producing great jets of flame by their ignition. Mr. Galloway has now satisfactorily proved that hydro- carbon gas is by no means the only source of dangerous explosions. Coal-dust mixed with air forms an explosive of terrible potency, and in most of the great colliery explosions it has been a serious factor, in some cases probably by far the most serious. A small explosion of gas, which alone would do no mischief, may operate by blowing up and firing the dust in its immediate neighbourhood ; and this secondary explosion may do the like furliier on, and thus the blown-up dust may act like a train of gunpowder with the most terrible results. The drier the pit and workings, the greater is this danger, and as we descend to deeper and deeper seams, dry workings become more and more common, and thus the coal-mines of the future will become progressively more and more dangerous. We read in pretty books about the miner's glow-worm lamp, and a pretty picture is thrown upon the magic-lantern screen of the lecturer, displaying a collier at work with a bottle full of these pretty creatures hanging by his side to cheer and guide him in his work. I doubt whether such a pretty lamp ever existed outside of thei-e pretty books and pretty pictures. It may have been tried, but, having kept a few pet glow-worms for a couple of years in a fern case, and watched their habits, I conclude that they would object to being bottled in crowds, and would not waste their ilhuuinating energies when thus imprisoned, especially as they light up for the purpose of courtship only during a short courtship season. The " steel mill " was really used. It was a wheel with steel periphery, which, when raf>idly rotated with a flint pressed against it, threw out a shower of sparks. These gave sufficient light, but they were also capable of firing the gas. I have illustrated that to a class by thrusting a brightly-heated iron wire through a bladder containing a mixture of hydrogen and oxygen gases, which thus treated explodes instantly. The spai-ks of the steel mill are simply incandescent particles of steel. The introduction of the wire-gauze lamp altered all this. Herious explosions that occurred in Durham in 1812 led to the formation of a Society for the Prevention of Accidents in (Joal-miues. It was at a meeting of this society in Sun- derland in 1813 that Dr. Clanny, of Newcistle, exhibited his first lamp. He had worked upon the problems for some time. George Stephenson, then a humble engine-wright at the Killingworth Colliery, Newcastle, was doing the same, and practically introduced a wire-gauze lamp in 1815. His first lamp was ready on October 21, further improved on November i, and fairly and practically in use November 30 at Killingworth under the name of the " Geoi'die Lamp." I will not enter upon the controversy respecting the per- sonal merits of the difterent inventors beyond expressing my opinion that the merit of Davy was rather that of demonstrating the rationale of the action of the wire gauz3 in resisting the passage of flame between its meshes than of the invention of the lamp. There can be no doubt that too much has been claimed for Davy, Smiles, in his Life of George Stephenson, concludes that the illustrious chemist and the humble engine-wright arrived by wholly independent paths at a knowledge of the facts concerning the non-passage of flame through tubes and small apertures. The principle upon which the efficacy of the Geordie or Davy lamp depends may be easily demonstrated by lowering a piece of wire gauze upon a common gas flame. As the gauze descends it will be seen that the flame does not pass between its meshes, but is effectually extinguished when it touches the metal. On applying a light to the upper surface of the gauze another upper flame appears, which is evidently a continuation of the partially-extinguished flame below. The gas passes between the meshes, but the flame cannot. Neither can a flame travel through cold metal tubes of small bore ; but if either the gauze or the tube be made red-hot, it no longer stops the flame. A further demonstration is afforded by making a candle with a small thread wick, and when the wick is lighted pas.sing over it a metal ring with an opening equal to the whole width of the flame. Although presenting no mechanical obstruction, the flame is completely extinguished by the cold ring. The reason is very simple. The flame is due to the energetic combination of the hydrocarbon gas with oxygen, but this combination does not occur unle.ss the gases be heated to a certain point. This heat, which is necessary for the continu.ance of the combustion, is carried away by the metal, which is a good conductor. The potency of metal in carrying away the heat of a flame is well shown by stretching a pocket-handkerchief, or piece of rag, over the convex side of the bowl of a silver spoon, and plunging the fabric into a gas-flame. It may be held there for some time without being even scorched, but if the experiment be repeated on a wooden spoon a hole is rapidly burned in it. The flame of a jet that is issuing with some force — as from a blow-pipe or Bunsen burner — may pass through the gauze according to velocity of issuing gas and size of mesh. Also, if the gauze is red-hot, its power of obstructing the flame is lost. These facts indicate a limitation to the practical efficiency of the miner's lamp. When surrounded with gas outside, the space within the gauze is filled with flame, and this warns the miner of his danger. But the warning may itself be fatal if he becomes alarmed, and rushes forward too rapidly, or sways his lamp cai-ekssly, and thus produces a through current that shall blow the inner flame outward. It is rarely that a human being is placed in a position demanding more of true courage than that of the miner when the flame of his lamp wick first elongates, then is surmounted by a blue cap, and finally flashes into a lambent flame that fills the lamp. He must hasten to the shaft for his life's sake, for if he is too tardy the gauze will become red-hot. If he rushes forward, or otherwise moves his lamp with a speed exceeding 4 or 5 feet per second, he will probably kill himself and all his comrades. In the midst of this dilemma he knows that others are in the same position, and that lack of courage and' coolness of anj- one may be destructivo to all. A number of devices have been adopted to diminish this danger, far too many for me to describe or even name here. Double gauze, glass protection outside the gauze, as in the " Geordie," are among these, and are more or less effective, but none are perfect. My surprise is not that so many colliery explosions occur, but that they are so few. The flippant comments on the ignorance of the miners that are so commonly made are really due to the ignorance of the commentators. The old story of the man who was descending a dangerous pit with a lighted candle on his hat, and, when reprimanded, replied, " Well, arnt I got my Davy ? " may amuse a magic-lantern audience, but those who know the simple but .shrewd-minded colliers are amused ia contemplating the self-sufficient silliness of the audience, who can suppose that their fellow-men, who are daily carry- ing their lives in their hands, are ignorant of the primary conditions upon which their safety depends. It is true that familiarity with any danger induces a April 2, 1888.] ♦ KNOWLEDGE ♦ 127 certain degree of recklessness, and jjossibly some disasters may have arisen from foolhardy fellows uncovering their lamps to light their pipes; but every collier can gauge the amount of explosive gases surrounding him by the state of his lamp tlame, and there is such a thing as public opinion underground. Any man known to be guilty of risking the lives of all his fellow-workers for the sake of a smoke would not escape unpunished by those upon whom the outrage had been committed, especially by the women above ground with vested interests in husbands below. Considerable progress has recently been made in the electric lighting of mines. Portable batteries and accu- mulators are used as sources of power. Their weight, as at present constructed, is a great objection. This will probably be diminished with further progress. But even this will demand protection, as the breaking of the glass bulb of an incandescent lamp would expose a filament of burning carbon nearly as dangerous as a flame. Perhaps their worst defect is the absence of the warning which is given by the behaviour of the common lamp flame. LIFTING GREAT WEIGHTS. IFTING exercises are open to the objection that they tend only to increase the strength of the body, activity not being increased by any of them. A man who follows lifting work only will be a slow mover, and what Blaikie calls "muscle-bound," meaning that the muscles themselves, by their undue or disproportionate development, limit the play of limb. Without agreeing with him that the full degree of lissomeness which can be attained by exercises of a contrary tendency is desirable, we must admit that a muscle-bound condition is disadvantageous. Yet lifting exercise, pursued with due consideration of the necessity for an adequ.ate amount of correcting exercise, is exceedingly useful, because in our daily life we constantly find occasion for the use of the lifting powers of the body. Lifting from the shoulder ought to be but a portion of the lift from the ground to the full height of the upstretched arm or arms. To lift a pair of weights from the ground, slowly raising them to and past the level of the shoulders, and thence to thrust them upwards, still slowly, till the arms straighten, is a much severer exercise than to raise the same weights from the shoulder only. And this last, again, is more trying than to send up the same pair of weights with sufficient velocity to carry them past the dead part of the lift, which ranges from the height of the mid-chest to a few inch&s above the shoulder. I, who can make no claim to exceptional strength, can readily (or could a year or two since, and suppose I still can) lift any one not exceeding 140 or 1.50 lbs. in weight to the full upward reach of my arms if I start right ; but I could not lift two-thirds of that weight slowly from the ground to above my head, or even slowly from the height of my waist. The way to lift any one easily in that manner is to place one hand upon the waist, passing the other under the knees so that the liody of the carried sinks somewhat, a motion resisted by the elasticity of the arms and legs of the carrier and converted into an upward motion from a height favourable to lifting — such rapidity of rise being communicated that the body is carried over the dead part of the lift, after which the arms readily straighten and carry the weight to the full height. The exercise is not to be recommended, however, as a safe one for the pei-son lifted, because the person lifting has to shift the hold of both hands on the way up, and if this is not deftly done an unpleasant fall is apt to result. (The last time I attempted a feat of the kind 1 was standing before a tall wardrobe with my wife, when she remarked, joking, "I wish I could get into that top shelf" — into whose recesses she had been vainly reaching. I naturally pretended to take her in earnest, and in another second she was on the level of that shelf, but I fear not more favourably placed for getting what she wanted than when on the floor. In that case, however, there was no danger of a fall because of the wardrobe's position. ) Nathalie, a French female gymnast, was able, according to Farini, to take two .5G lb. weights from the ground, one in each hand, and put them slowh' above her head. Let those who can easily put up two such weights with a quicker motion, try the slow movement, even with much smaller weights, and the}" will recognise the difference. Farini pointed out to Charles Reade that putting up an agile gymnast is mere child's play to this, " because, in dealing with the live object, the strong stoops, the agile springs, and the strong arms are at an angle of -tS before the weight tells ; now," proceeds Reade, " the ai-ms, as they near the perpendicular, can hold up three times the ^\eight they can put up." (He should rather have sjiid that the arms as they near the perpendicular can put up three times the weight they can lift up before they reach that position : they can, however, lift up from the ground twice the weight they can push up to their full upward reach.) Lifting at arms' length exercises, so far as the arms are concerned, an entirely different set of muscles from those used in putting up weights. Nor can strength be so satisfac- torily tested, or compared, by the former as by the latter exercise. A long-armed man is here at a disadvantage, and judging by the weight he can lift, might appear weaker than a short-armed man really of less power in the arms. I remember the disgust with which when at college I found men whom I knew to be no sti'onger than myself able to lift greater weights at arms' length, till I noticed that the unusual length of my arms, which span horizontally fully half a foot more than my height, put me at a disadvantage, owing to the extra leverage involved. Our strongest man at Cambridge Univei-sity then (18.")<3 to 18G0 was my time) was, I believe, Mr. Duncan Darroch, who rowed "four" in the 'Varsity boat in 1858, the year when Cambridge rowed the fiimous race (which they won by 2 feet 6 inches) with the London (_'lub eight, manned by Casamajor, Playford, the Paines, and other famous oarsmen of the days before sliding seats were invented. Mr. Howard Snow, afterwards one of the masters at Eton, and now — but with altered name — head master at Cheltenham College, and himself a fiimous oarsman, stroke of the Cambridge boat in 1857 (and bracketed first in classics in 1858), wrote of Darroch, in somewhat doggerel rhymes : — He'll lift as much as any other one can Will Duncan ; He has the strength of an entire barrack, Has Darroch ! Darroch could lift a 56 lb. weight at arms' length. But Darroch was short-armed for his height, and, as I remember him, a muscle-bound man. Few men can expect by any amount of training and practice to acquire the power of lifting such a weight as 56 lbs. at arms' length. Thirty pounds would be a very fair arms'-length lift for men of average strength ; and even that would require exercise and training. Very good exercise in lifting can be obtained without special apparatus, as by lifting chairs in different ways. Thus the chair may be lifted at arms' length by a front rung gi-asped knuckles upwards or knuckles downwards ; or by the lower end of a front leg — the back being in every case brought to a vertical position, and so maintained while 128 ♦ KNOV\rLEDGE ♦ [April 2, 1888. the lift lasts. Strength may be tested either by the weight of the chair lifted, or by the time during which the chair is held out. It is noteworthy that often the man who can lift the heaviest chair at arm.s' length in some particular way, may be surpassed by another when the mode of lifting is altered. And, again, those who lift the heaviest weights in these ways are not always tho.^e who can maintain their hold longest. R°solution comes in as a factor in the last-named test. One will often see a great and strong but easy-going man lift out at arms' length a weight which another cannot bring for a moment to that position, who yet will not hold out half that weight for half the time at which it will be held out by the weaker, whose resolute will enables him to sustain his hold to the very last. In all these forms of lifting the arms are chiefly con- sidered. Yet in reality the lower limbs have their work to do, not only in sustaining the extra weight, but in sustain- ing also the weight of the body. It is only in exercises which require the body to be lifted from the ground that the legs get no woi-k. Such exercises are among the severest tests of strength, bacause they reverse the usual order of things. To a sloth, accustomed always to have its weight suspended, such exercises would come naturally : to men they involve always a certain extra amount of ditiiculty as compared with exercises in which the sustaining power of the legs is called into action. I need not touch on feats in which the body is merely raised from the ground a certain number of times by the action of both arms or of one arm only, or from a single finger — as can readily be done after sufficient practice. I do not, indeed, know what is actually the "record " for feats of this sort. But for the actual lifting power of the arms, I know of no feat ever accomplished wliich has surpassed one which Nathalie, the lady mentioned above, was in the constant habit of performing. She could extend her body from the horizontal bar, supported only by one hand grasp- ing the bar, knuckles downward ; then (for so far the feat was not uncommon) she could put the other hand behind her and take the bar with it, holding the body horizontally by that hand. Farini told Charles Ileade that be had never met with a male athlete who could do this ; j'et, added Reade, "it was not knack: it was complete eithcr-handed- ne.ss, coupled with gigantic strength." Speaking of lifting the weight of the human body, I may touch here on a somewhat absurd fancy many entertain about an experiment in which four per.sons lift a fifth on the tips of their fingers. I have repeatedly heard this ex- periment spoken of as something very marvellous. The person to be lifted draws in his breath and stiffens himself generally ; the four who are to lift him also draw in full breaths, " and then," the story goes on, " he is lifted with- out any apparent effort " — meaning, of course, that he is lifted quite easily. As, indeed, why should he not be 1 Tlie person lifted usually weighs about 120 lbs., and each of 'the four lifters would think it no great effort to lift 30 lbs. with the forefinger. Drawing in a full breath is always a good preliminary process for any muscular effort ; and after this process each of the four lifters does easily what he can always do easily, lifting not the fifth person bodily, but just a fourth portion of his weight — 30 lbs., or -10 at the outside. In all lifting feats the lower limbs are really taxed, even though the arms seem to do the work. To suppose other- wise were to make a mistake as foolish as that of the Irish- man (though why such stories should be put always upon Irishmen I do not know) who thought to relieve his horse by putting the meal sacks, which formed a large portion of his load, over his own shoulders. I,ift a weight how we may, the legs have to bear it. It will be understood, then, that whatever weight the arms may seem to lift in any ex- periment, the whole body can be made to lift much more. In all stories of great weights which have been lifted it will be found that the lifting power of the whole body has been in question. This, indeed, is true of all the most remarkable feats of strength which have been recorded. One need not consider the feats of a Hercules {i.e. Herakles) or of a Samson, seeing that both one and the other is a sun- god, of whom naturally wonderful feats are narrated. (The very name Samson means the glorious sun.) Feats actually noted and recorded are sufficiently surpris- ing witliout considering feats purely mythical. The famous strong man, Topham, of Islington, may be considered a fair illustration of those cases of exceptional development of strength — without exceptional muscular development — of which we hear from time to time, as we hear from time to time of men remarkably large or remark- ably small. It would seem as though some physiological peculiarity in such men enabled them to get from their muscles much more nearly their full action than (as physio- logists know) is ordinarily possible. Toisham could take a kitchen poker and twist it round hLs neck in such sort that four or five strong men were unable to untwist it — a feat which he accomplished as readilj' as the twisting. He could squeeze a pewter pint-pot flat in bis hand, double up a crown piece (familiarl}' known in former times as a " cart-wheel ") with his fingers, and break a short piece of tobacco-pipe by side jn-essure between two fingers opened out in V-shape. This last feat, as depending on the action of muscles very seldom trained to do any work, is specially remarkable ; it serves to confirm the belief that Topham was able, as it were, to charge his muscles with an exceptional supply of nerve force. They were certainly not unusually developed, though of course they were above the average size. Van Eckeberg, an athletic German, lifted a weight of nearly 3,000 lbs. by the use of the strength of his whole body. He stood within a well-balanced framework heavily loaded, and to be raised by straps attached to a strong waist- band. The lifting power was obtained by straightening his lower limbs (almost straight just before lifting). The heavily- loaded framework was thus raised an inch or two, a slight swaying movement showing the spectators that it was really free from contact with the ground. So powerful was Topham's frame for this sort of work, that he pulled against a strong dray horse- -his body being in a horizontal position, and the pull of the horse being resisted by the pressure of his feet against two stirrups, so that the action was akin to that of Van Eckeberg's in the lifting experiment. Unfortunately, after he had successfully resisted the pull of one horse in this way, he had one of his knees .shattered in an attempt to pull against two horses, and thereafter he was disabled from the performance of feats of this kind. Great care indeed is required in all lifting exercises to avoid any sudden change in the direction of the pull. The secret of this great lifting power of the legs in such work lies in the fact that the action has that exceedingly effective leverage which is employed in the Stanhope Press — firmiliarly known, in fact, for this very reason, as " knee leverage." When the legs are nearly upright the knees may be perhaps half a foot from the position they take when the legs are straightened. While they move through this half foot the body is not raised more than perhajjs half an inch ; consequently the power used in straightening the legs is multiplied into a twelve-fold greater lifting power. It is beaiuse of this powerful knee-straightening action that lifting exercises are apt to develop abnormally the muscles of the lower and inner end of the front thigh.

Blaikie learned in this way, at the age of seventeen, to lift a thousand pounds after only six months' practice. These who prefer to lift an actually measured weight will find it necessary to adopt some such plan as was employed by Topham, preparing a framework to bear the weight, and standing in its midst so as to lift the weight by means of symmetrically-attached straps. For the body cannot, when all aelant, bear such a weight as a thousand pounds. Whether such exercise is good for the body as a whole depends a good deal on the opportunities which a man has for corx-ecting an abnormal development of the lifting muscles by means of other exercises, increasing the develop- ment of other muscles and giving activity as well as strength to the frame. NOTES ON AMERICANISMS. Habitak. Corruption for the French word Iiahifant, a landed proprietor on a small scale. The word is seldom heard outside Canada on the northern side, and Louisiana on the southern. When heard in the middle States, it usually has a sound as entirely different from the Fiench pronunciation as " Movey Star " is different from "Mauvaises Terres," or " Lagrange " (rhyming with " range ") from the French " Lagrange." Had have. Hadn't oughter, and kindred combinations and abominations are heard about as frequently in the States as in the old country. Would that Bartlett " had have " been justified in imph'ing that Americans only use expressions which they " hadn't oughter " such as these. Hail fro.m, To. The good old sea-phrase, " hail from " for come from, bdomj to, is heard in America as in England, though America has done her best to destroy her own sea- carrying trade. But to call " Hail from," thus used, an Americanism, is as absurd as it is to call " Hang out," for live inside, American. Bartlett naturally does both, seem- ing to know as much about English usage as the Saturday Riview knows about Americanisms. Hamsiock. 1 . The use of this word for a swinging- bed, though of South American origin (Spanish Jamaca) has now been for more than a century so widespread that to regard it as an Americanism would be absurd. The use of the " hammock '' as an open-air couch in gardens, on porches, and so forth, is, however, undoubtedly much more common in America than in the old country, the summer climate inviting to lazy ways of lying (or " laying," as nine tenths even of the " society people " of America call it), reclining, sitting, and so forth. The grandsons — aye, and the .sons, too — of men who in England would be ashamed to be lolling and sprawling half the time, loll and sprawl all the time in America. But for the constant infusion of new blood, the American population would develop in a few generations into a race no longer using chairs, except of the lazily rocking sort, and regarding the upright position as involving an exhausting tax on the energies. 2. The word Hammock is used in the Southern States, for " a piece of ground thickly wooded, whether a prairie or a hill, and distinguLshed from the immense forests of thinly scattered pines, which with a few exceptions cover the whole face of the country" (where the word " hammock" is in vogue). This definition is from an article in the Xorth American Revien: The word is not found in either Webster or Worcester. I can find no evidence as to its origin, since it is clearly quite distinct from the old word " hummock " for rounded knolls. It is painful to have to admit ignorance about an Americanism, with the Saturda;/ Revieir ready to pounce on everj^ indication of my having undertaken in these " notes " a task for which I am totally unfitted. I may, however, remark that even as I had been myself using for years two of the Americanisms which that omniscient weekly strove to exploit as " recent inventions," I know by actual experience what "hammock land" is, though I am unable to say how the word " hammock " came into use. I write these lines with half a dozen tracts of hammock land in view, and with one such tract within five minutes' walk, a portion of which has been cleared away for my own special " potato patch " (the " potato " growing on it being at present grape vines, however). I must ask the readers of these " notes " to excuse me for occasionally reminding them that I have had (and have) somewhat exceptional oppor- tunities for comparing American with English expressions and ways. I should not have thought of so doing had not the greatly daring review which has recently made itself for ever famous by attributing to Sir William Jenner the in- vention of vaccination — when he was presumably a very young man, a century ago — written of my modest "notes" in terms implying that they had been evolved from my moral or immoral consciousness. Yet are there some things, strange to say, which the average Saturday Review writer really does know, and know by the best of all possible evidence, and among these is the fact that some writers would for a consideration pen a treatise about the Himalayan Snows, with no wider experience than a back attic in Grubb Street would afford, or discuss the campaigns of Napoleon or of Moltke with no better knowledge of the military art than may be obtained in school- boy scrimmages. Haxd. — It will hardly be believed that Bartlett includes the expres.sion " hand " used in reference to proficiency — as when we say that a man is a " good hand " at fighting, or a " poor hand " at accounts — among Americanisms ; but he does ! Handsome for generovs, is of course as thoroughly English as any usage can well be. But Bartlett who includes this usage among Amei-icanisms, overlooks an expression which, though occasionally heard in England, is so much more commonly heard iu America, that it might well have been one of Bartlett's set. In America the expression' " he did the thing handsome " would not be thought remarkable, though a small percentage might be aware that it is incorrect. Hang. To get the " hang " of anything, meaning to learn its nature and peculiarities, is an expression which has long been in use in the old country, but is perhaps oftener heard in America. Hang, Arol-nd, To, signifying to loiter about, is only an Americanism in regard to the word " around," which is used here where in England we should say "about" or " round." I am inclined to think that the word " around " constantly used in America where we say " round," is in reality the more correct adverbial form, " round " being a corruption by clipping, which in strict- ness should be written " 'round." I have myself become so accustomed to the American usage that I have found the word " around " making its appearance frequently in my ^vriting, insomuch that an English friend of mine whoiskindly helping me in the revision of my " Old and New Astronomy " has had occasion to alter " around " into the more usual "round" in quite a numter of places. I was thus led to examine my earlier works, written before I had lived in America, as I have during about six years out of the last fifteen, partly expecting to find that I used the word "around " as freely then as now. But in my " Saturn and its System " I find that where I should now be apt to write" " around " I wrote either " about " or " round," the 130 ♦ KNOAVLEDGE ♦ [April 2, 1888. former much the more fiequently, probably because the word " about " is constantly used in mathematical works when rotation or revolution is in question. In passing, I may remark that my first acquaintance with the American usage was formed when (somewhere about the year 1855) I heard Mrs. Florence as the " Yankee Gal " singing tbe well-known song " Bobbin' Around." But the refrain " As we went bobbin' around," familiar though it became, did not so far affect my English as to make me write of Saturn as bobbin' around the sun. He still continued seilateh-, even Saturninely, to " revolve about " the ruler of the solar system. Hano Out, To. Bartlett not only regards this as an Americanism, but identifies it as Western, almost as Chicagoese. It was already old in England before Chicago began to be a place. Those elegant medical students, Messrs. Bob Sawyer and Benjamin Allen, could have enlightened ^Ir. Bartlett more than half a century ago about this bit of old English slang. Haxg Up One's Fiddle, To. To give up ; an expression frequently heard in the Middle and Noi-thern States, but probably of southern (nigger) origin. " Hang up nm fiddle and um bow-ow-ow " will be recognised as part of the refrain of a very ancient nigger song. Happex in. To. To come in accidentally, short for " to happen to come in." Happen on. To. To happen to meet, short for " to happen to come upon " such and such a person. The later, but now not very recent, Americanism for this idea, is " to strike." Where of old a man would say, " I happened to come on our friend Mr. Jones yesterday," an American would formerly have said (and many Americans would still say), " I happened on friend Jones yesterday," while an American of to-day, especially if a westerner, would be apt to say, " I struck Jonas yesterday." Hard Case. A term not unknown to the British police for an irreclaimable criminal, extended as an Americanism to hopeless rakes, blackguards, drunkards, poker-players, et id r/enus omne. Hard Pan. Bartlett describes this as primarily a geolo- gical term ; but though a geologist may occasionally speak of a hard and water-tight stratum of hollow shape as a hard pan of clay or gravel, or describe such a stratum as the hard pan below such and such strata, yet the term " hard pan " has not in this indefinite form }"et taken its place in the geological vocabulary. " Hard pan " as an Americanism, signifying the bottom of things, is doubtless derived from mining experience. A man might dig for gold through sti'atum after stratum without altogether losing hope, till he came down to the hard water-tight stratum below ; but when he had thus reached " hard pan " he gave up. To say, then, " W'e are coming to ' hard pan,' " or " we have now reached ' hard pan,' " is equivalent to saying. We are now beginning to know with certainty, or we can now form a definite opinion. The ide;\ is more poetically expressed, but with the same inner significance, in Wordsworth's well-worn lines : — To the solid ground of nature Trusts the mind that builds for aye. Hard Row to Hoe, A. A tough business to get through. Haliburton has made us familiar with this expression as an Americanism, but it may be regarded as surely of English agricultural origin. Hardshell, used as an adjective for thorough-going, is probably a pure Americanism, since the term was originally suggested as the difi'erence between the hardshell and soft- shell crab, and we have no soft-shell crabs in the old country. {To he continued.) THE STARS OF OTHER TIMES. {C ontimoed from page 112.) HE southern stereogi-aphic map in the present number needs no separate explanation, being drawn on the same plan as the northern, and having the same general interpreta- tion. It is, however, altogether the more in- tei-esting map of the two. The stars north of the ecliptic have alwaj's been visible up to about 60° 30' north latitude, and the stars in the northern map, which ranges 10° south of the ecliptic, have been always visible, at suitable times and seasons, as far north as about 56° 00'. But stars shown in the southern map are for the most part such as are only brought into view in northern latitudes by the .slow precessional motion of the equator along the ecliptic, and after being thus in view for a time — hundreds, or it may be thousands of years, according to their position on the star-sphere — are carried out of view again, so a-s to be unknown in the latitudes where they had so long been known, during hundreds of future generations. Moreover, the aspect of the .southern stir groupings as they rise to their greatest height above the horizon of northern lati- tudes, changes continuously with the precessional movement, much as the aspect of northern star-groupings changes during the night. As Cassiopeia and Andromeda, for example, Auriga, Bootes, and Cepheus, are sometimes pre- sen'ed in such positions that tbe figures associated with them have the uprightness desirable with men and women, but at other times are aslant or inverted, prone or supine, so the ship Argo and the altar Ara have held very diflerent positions at their culmination in past times than now, and will continue slowly to change in position as the precessional motion continues. Doubtless it is due to such changes as these that several southern constellations are no longer recognisable from any resemblance between their configuration and such objects as altars, .ships, animals, and men. For a star-grouping which will readily suggest to the imaginative mind the idea of some known object when that object, so imagined, would be in a natural attitude, will suggest no such idea in any other position. To see this we have only to consider the case of the constellation Orion. In one position this grand star-group suggests the idea of a giant holding a shield of some sort in front of him, and standing upright, while in another it suggests the idea of the giant raising himself towards the upright position, and in yet another, that of the giant slanting forwards as if running down a slope. But seen near the horizon at the equator, when the giant would have to be imagined either prone or supine (supine in the east and prone in the west), the constellation does not suggest the idea of a man at all : while in the southern hemisphere, though the idea of a giant is again suggested, it is a giant of another figure and presented in a diflferent way, the shoulders of our northern Orion representing the knees of the southern giant, and vice versa. Thus it becomes a problem of some interest to determine how the star-groupings associated with diflerent objects and figures appeared when those particular constellations re- ceived their names : for thus not only may we be able to correct our determination of the date of such naming, but we may obtain evidence more or less satisfactoi-y respecting the occurrence of changes among the stars, we may be able to find some explanation of the ideas of men in old times respecting the constellations, and we may even be able to find an interpretation of certain religions which were associated in far-off" times with the stars. The study of the .southern star-chart will serve to show Ai'KiL 2, 1888.] ♦ KNOWLEDGE ♦ 131 THE ZODIAC AND THE SOUTHERN STARS ln'Kii't''A.l'roctor. Soiilo of Stai- Ma.^iiitudo3.

I would invite special attention to the position of the ship Argo, which was horizontal when cul- minating at the former epoch, aslant in the days of Hippar- chus and Ptolemy, and is now more aslant still. As a ship may be said to be in her natural position when on an even keel, we have in this result evidence of some force to show that the constellation received its name at the earlier period, or more than 3,000 years before the Christian era. At any rate, further inquiry into this question is suggested. {To he continued.) EVOLUTION OF LANGUAGE. By Ada .S. Ballin. X.— ROOTS AND THEIR USES. AVING spoken of the probable origin of a large number of roots, we can now turn with interest to the use of roots in the various languages known to us. As Mr. Garnett announced in 1849, after a searching analysis of more than eighty languages, word endings were originally uninHected pro- nominal roots, with a locative signification. Roots are all that Ls primitive in language, and sentences are even now found wholly composed of these elements. In a private letter to me, Mr. Frederick 11. Balfour — than whom few are more familiar with the Chinese lan- guage and its dialects, as used at the jiresent day, as well as with the classical or literary languige — once observed : " I may safely say that it would be difficult to write one sentence which did not consist of roots, for every character embodies a root idea, and is used for ordinary purposes, in literature as well as conveisation, without inflection." According to the manner in which roots are combined, we find three stages of language : — • I. The radical, in which, as in Chinese, roots are used independently, supplying the place of all parts oi speech, as « cluing, " employ stick," meaning " with a stick." II. The agglutinative, in which two roots may be joined to form a word, in which compound one root may lose its independence, the stage called by Max MiiUer, to whom this classification of language i.s due, the terminational, exemplified by the Turanian family, in which the lOot stands out clear from the termination, as, for example, from the Turkish root hakar, to regard, we have hakarim, hakar-sin, and so in conjugating the verb. III. The inflectional, in which two roots may be joined together to form words, both losing their independence in Aryan and Semitic languages. As long as every word or part of a word is felt to express its own radical meaning, a language belongs to the first or radical stage. As a specimen of this stage, Chinese is the stock example ; but although it is alwa^'s regarded as a monosyllabic language, a large proportion of its parts of speech are formed of two charactei-s (root words) joined or used in apposition, each of which supplements and explains the other. The combination thus eflected presents a distinct dLssyllable. As Sumner says: — " A word in Chinese //*«;/ consist of one .syllable, but, from the want of grammatical inflections, and from the limited number of .syllables in use, a monosyllable is rarely intelligible when alone ; it generally requires some adjunct to limit or strengthen its meaning." Chinese words have neither classification nor inflection, and distinctions of case, number, person, tense, mood, and so on, are non-existent. The meaning of a character or word, and its place in the sentence, generally determines to what category of our grammar it belongs ; but frequently auxiliary syllables and particles distinguish the parts of speech. The syllables which serve to strengthen the original notion expressed by the chief syllable denote the (cjent, an object, the completion or expansion of the chief idea, or " are purely formative in character, and produce nouns or verbs, adverbs or adjectives, as conventional u.sage has determined." * A noun, from its position, may become a verb, or it may so stand with another noun as to signify a preposition. Thus hid-shan, " descend a mountain " ; hid-fCimj, " lower room " ; shdn-hid, "at the foot of a mountain," hid in other combinations meaning " below " ; icai, " exterior " ; ivai-ktro, " foreign countries " ; kivo-wni, " out of the country." The Chinese word cannot therefore be regarded as really either noun, verb, or other part of speech, since, under different conditions, but without any change in itself, it may come to represent each in turn. Chinese words which may be classed under our head of nouns, as far as regards their use or derivation, may be divided into three kinds : — 1. Primitive nouns, mono- syllables bearing their original signification, and generally used in the monosyllabic or crude form, such as jin, " man " ; fan, " rice " ; ch'a, " tea." The class is not a large one, and the monosyllables are not understood by the ('hinese when pronounced separately, being only used in connection with other words — as "a man," >/i kb {one), jin ; k'ifdn, '• to eat rice " = " to dine " ; fsaicfdn, " early rice " = " breakfast " ; or wan-fan, " late rice " = " dinner " ; and so on. 2. Nouns derivative, made by the addition of one or more formative syllables — a much more numei'ous class, which always remain nouns, while some of the former class may be used as verbs. The formative syllables in these nouns .serve the same purpose as terminations in inflectional languages. Thus jin, man; kfmg-jin, a workman; sJieii, hand; shwul-sheu, "water hand," a sailor; ilr, infant; nil ilr, " a girl " ; jin-ar, " a man " ; kiii, " family " ; jin-kid, " people." 3. Composite nouns, which are formed by the connection of two or three .syllables, each of which retains its proper signification. The same syllable may be repeated, as nal-nal, " married lady of rank " ; or synonyms may be united, as sm-c/idng, " the heart, the feelings " ; or a noun may be formed of two verbs, as Mng-wei, " actions," from two words meaning, ' to do." Nouns expressing the abstract notions of verbs are generally formed in this latter way, just as the infinitive is used in Greek and German — ro TV)(fiir, das Leben, das Haben, and so on. Two adjectives are united to form nouns, as chln-pail, " precious-precious ":=a jewel ; yiu-mun, " sad-sorrowful "^sorrow. Many nouns are formed by placing generic terms, as, for example, the equivalents for tree, stone, fish, &c., after the special object ; as we say limestone, fir-tree, and the like. Words expressive of time and place, generally used as prepositions or adverbs, also enter into the composition of nouns, as in the former exam- ples : tsaii-fdn, " early rice " ; Ger., Friih-stilck, " early piece " ; wdnfdn, " late rice " ; Ger., Abend-brod, " evening bread," for the evening meal, supper; k'ln-ji, " now-day ":= today. Cf. the uses of riv and ttu/Vu. The modes of expressing abstract notions are exceed- ingly interesting. A common method is to combine opposites, as " light-heavy "^weight, " many-few "=quan- tity, " long-short "=length, " high-low "=:height, and so on. Others are formed by the addition of such words as ?) bj- joining an auxiliary to the primitive, as tie-si, " fall, die "= fall down dead ; (c) by prefixing to one verb another denoting power, oriip the islands from the ocean, is by no means ])vominent. We have details of the descendants of poly- gamous gods which rival the genealogical chapters of Scripture in their dryness ; but these are followed by many variants of the wide-spread myth of the separation of earth and sky, the substance of which, old at its base but new in much of its super.structure, is as follows. Eangi (heaven) and Papa (earth) were lying together, and all between them were vines and creepers, tender plants, and red water. All was dark, and their children were born therein, but having seen a glimmer of light in the armpit of Rangi, they re- solved to separate their parents. However much the myths ditfer in detail, they agree in assigning this task to Tane. Having sundered apart his fiither and mother, he propped up his father, but not liking to see the nakedness of the pair, he caught stars and threw them heavenward " to beautify Rangi, that he might be comely," and then went sunwards to bring trees and plants wherewith to clothe Papa. But the love of the parted ones was unabated ; the tears of Papa are carried to Rangi as mist and dew, and the sighs of Rangi are borne on the west wind to Papa, " tickling his ears " ; in another myth " he sighs for her in the winter, and this is the origin of ice." The dualism of Christian and other theologies peeps out in the myth that after Tane went to heaven, Tu and Eoko destroyed the ci'eatures which he had gatheied for food, and then, follow- ing him, fought a battle on the borders of heaven, when Tu was slain and Eoko cast down, like Satan and his wicked angels. And passibly we have some mixture of Eastern and Oceanian legend in the creation of man out of red clay, and of woman from a sloppy mixture which Tane makes in human shape, and then infuses life into it by processes which cannot well be detailed here. Neither are the tradi- tions without a deluge, which Ta-whaki caused by stamping on the floor of the heaven until it cracked, when torrents of water flowed down and covered the earth. When he died, the * I.e. tabu, or taboo, as we commonly spell it, signifying the setting of something apart from human contact, itvesting it with an inviolate or sacred character. We have given the word another meaning, applying it to forbidden subjects, as " tabooing " a conversation. green parrots took some of his blood and stained their feathers with it, hence the red colour of those birds to this day. Parallels and resemblances are not evidence of borrowings ; the same explanations of like ])henomena are often given by races at corresponding levels of culture. But, in the cases before us, we know how probable it is that alien elements have been assimilated, or that they have become confused with indigenous elements in the minds of chiefs who, as Mr. White remarks, " would have given the whole Maori hi.story," both true and legendary, " but, unfortunately for us, these men were born too late ; that is, their education began after the Whare-Kura and its rites had been neglected." The lament or incantation which heads each chapter evidences not only the grace and fulness of the Maori language as a vehicle of poetic feeling, but also the truly astounding aptitude of the Maori mind for abstract thought. Remembering that the idea of a Supreme Being did not exist among the tribes, we, however, need very satisfactory proof that the subtle speculations embodied in the theory of Aeons, beginning with the age of thought and ending with the age of gods and men, and that such definitions as those which are given in this volume, e.g. of Tua as mean- ing " Behind all matter," and " Behind that which is most distant," are the genuine equivalents of Maori thought, and not the unconscious gloss of philosophic interpreters. How easy it is to make a serious mistake in the New Zealand tongue the following story, which is cited from Mr. Buller's work, shows : — I knew a missionary who, in the early days, had a lesson in Maori in not the most pleasant way. It was expedient to give an occasional present to the chiefs in order to secure their good offices, for the lives of missionaries and their families hung upon their caprice. One day the said missionarj' was giving a small three- legged iron pot to an old chieftain, who, instead of being pleased with it, flew into a great rage, much to the surprise, and somewhat to the terror, of the donor. The cause of this was, he had said, " Mou tenei," whereas he ought to have said, " ilau tenei." Both phrases have, in English, the same meaning, " This is for you ; " but, in M.iori, there was an important distinction. By the latter form he would have been understood to say, " This is an iron pot for you to do with as you please;" but, by the unfortunate, but ignorant use of the other form, he was heard to say — what he never Intended to say — " This is an iron pot for you 1o he cookfd in." Hence the fury of the insulted chief. ROYAL VICTORIA HALL. {To the Editor o/ Knowledge.) LECTRIC BELLS " formed the subject of a very interesting lecture given at this hall on Tuesday last by Prof Sylvanus Thompson, who, instead of travelling hurriedly over a large space of ground, confined himself to explaining thoroughly and clearly this small department of electric science. Ringing one of the many hells displayed on the stage, he inquired where the power was to be found which rang the bell 1 Imagine an intelligent savage investigating one of our common house-bells, with a crank to convert a per- pendicular into a horizontal pull, tracing back the wires till he found the man at the other end pulling them. In like manner we must trace out the less obvious force at work in the ringing of an electric bell. It is no case of pulling, for the wires hang slack. We find one of the wires is con- nected with two bobbins of coiled wire, which, when the bell is ringing, constantly pull and let go a jiiece of iron connected with the clapper of the bell. The other wire is connected with thLs piece of iron, passes thence to an electric battery, Apkil 2, 1888.] ♦ KNOAVLEDGE ♦ 137 and on to the button whicli we pi-ess when we want to ring the bell. By pressing the button we make metallic communication between the free ends of the wires, so that a current can pass from the battery along them ; and this current acts on something contained in the wire bobbins. That something is a core of soft iron, which, while the current passes along the wire which surrounds it, becomes strongh' magnetic, and attracts the iron keeper connected with the clapper. But, by a very ingenious con- trivance, at the moment the iron is attracted the metallic connection is broken and the current ceases. The iron coio thereupon ceases to attract the keeper, and the current is re-established, a jerk being given to the clapper each time this happens. A number of experiments were shown, illustrating both permanent and induced magnetism ; and a variety of forms of electric bell were exhibited, from very sweet-toned church bells of a small size to a contrivance intended to wake up servants, which, when once the button is pushed, goes on ringing inces:?antly till the tormented servant goes to the bell and pulls a handle. Dr. Thompson then went on to inquire where the power comes from to produce these results, for we can never have results without a cause. There is no such thing as " perpetual motion." Wherever we have power, something must be spent to produce it. Here, it is clear, the power starts from the battery. "What is used up there ^ In ordinary steam-engines we burn coal ; in a gun the fuel is gunpowder ; in a battery it is zinc. Zinc is combustible in air, though not freely so, and in a battery it is burnt in acid, the combustion going on while the current passes and the bell rings, but at no other time. There are methods of obtaining a current without a battery ; for instance, by turning a handle, and causing a coil of wire to rotate in presence of a permanent magnet. But the same principle holds with all. Something is used up to obtain the power ; in this case the man who turns the handle plays the part of engine, and the food which he has eaten is consumed to do the work. Dr. Thompson, in the course of his lecture, spoke of the large extent to which electric power is used in Xew England, as many as 200 shops in one town being supplied with it, from wires laid under the streets, as our gaspipes are laid. But for vested interests, he said, the same thing might be done in London, and power supplied to workshops with much economy both of sp.ace and money.

Longmans, hearing from the printers that a last revise had yet to be sent out, supposed there w£s some risk of the issue of Part II. being delayed, and very prudently (on that — mistaken — view of the case) ordered the postponement of the issue of Part I., lest there should be any breach of continuity in the issue of parts. ■If ^ * The original delay (from January 1 to March 1) was not my doing, but as I was disabled for two months by a serious accident the delay occurred ha])pily, for I think the issue must have been interrupted had Part I. appeared on January 1. * * * The New York papers of February 21 announce the death of a man named Romayne Dillon, who, though an utterly worthless ruffian considered in himself, aflbrded an interesting illustration of the inelHciency of American justice, where such trifling offences as murder and brutal assault are concerned — that murderous form of justice called lynch-law being the pleasing product of this inefficiency of normal justice. As I have for twelve years or so regarded this man as one who had had his pistol ready for myself— all un- knowing of his cheerful purpose — 1 take some personal interest in his case. DuRiXG the last fortnight of December 1875, I was a guest (most of the time) at the Westminster Hotel, Union Square, New York, my customary stopping- place when in that city. I used often to pace xip and down the ground- floor corridors, where, as I supposed, no guests had rooms, finding a sense of relief in this peripatetic habit from the monotony and solitude of hotel life in America for those of domestic tastes and proclivities. I noticed occasion.all}', but did not note, a kind of subdued growling (like old Bill Barley " in the beam ") as I passed a particular door. I had no idea that this gi'owling was in reality exceedingly por- tentous, and, as I have every reason to think, personally thi-eatening. * * * On the evening of December 31, when I was in the read- ing room, I heard a report which, in my inexperience, I regarded as due to the fall of some metallic substance on the marble pavement of "my" corridor. But other readers, " being acquainted with the [sound] before," knew it meant shooting, and in a second or two every reader was in the corridor. Here we found an unfortunate fellow — John Dilliber, his name was — sitting against the wall supported by one of the waiters. He had been shot, but the man who had shot him had gone back to his room. * * * Dilliber made the following statement while he was waiting for the elevator : " I don't know why the man shot me. He came out in his shirt-sleeves while I was walking up and down the corri. No more instructive example of the emptinesi of metaphysicil siJeculation could well be found. Insect Wai/s on Summer Days. By Jen.mett Humphreys. (London : Blackie &, Son. 1888). — Flower-Land. By Robert Fisher, M.A. (London and Manchester: John Hc3'wood. 1SS7). — We have classed these two books together as affording, each in its way, an excellent introduc- tion to natural history for children. Miss Humphreys makes each insect tell its own story, and has devised a system of inemoria technica of the generic and specific names of those so described in the shape of nonsense verses. As for Mr. Fisher's book, no child resident in the country, or who ever has the chance of spending twenty-four hours among heath, field, wood, or hedgerow, ought to be without it. It is a very long time since so admirable a little book for the ver}^ beginner in botany has appeared. Dottinjs of a Dosssr : Revelalioni of t/i; Innv Life oj Low London Ijodging - liousjs, by Howard J. Goldsmid (T. Fisher XJnwin, 20 Paternoster Square), is a little book calculated to be of tho greatest possible value in attracting the eye of the public to the wrongs of an unfortunate class, which has hitherto been neglected by phil.inthropists. Tho dosser is a person too poor to afi'ord a settled habitation, who, when he oi' she can scrape together tho necessarj^ four- pence, hires with it a bad for the night in .some low lodging- house, and, when the money is not forthcoming, promenades the streets all night, or finds a resting-place on a seat on the embankment or on a doorstop, if the policeman on the beat will permit it. The doiser is below the class of jnc- turesque poor for whom so much has been done of late ; ho would need a bath and a new suit before ho could enter tli! " People's Palace " at the East End i ho and his rags and his dirt have been hitherto beyond the pale of fashionable benevolence. INIr. (Juldsmid writes boldly of the wretched squalor into which these jioor unfortunates ai'e thrust by the inefEciency of the law respecting common lodging- hous.'s. The quotation on his title-pige is from the Common Lodging-houses Act of 1851 : '• Wiiereas it would tend greatly to the comfort and welfare of many of Her Majesty's poorer subjects if provision were made for the well orderino OF COMMON LODGING HOUSES," but his wholo experienc3 shows that no such jirovision has been made. With an admirable courage Mr. Goldsmid has obtained person.al evidence of the state of affairs by himself becoming an inmate of a large number of these houses, which may fairly be taken as ■samples of the rest. He has found them in a rickety ami broken-down condition, with improper sanitary arrange- ments; the kitchens, in which the lodgers sit and cook their .saxnty meals, filthy in the extreme ; tho bedrooms still more loathsome, invariably overcrowded, and the beds full of vermin. In some rooms, which can hardl}' accommodate thrca parsons, the law p^rmits eight to be huddled. Yet these places are periodically inspected, and " we must suppose, therefore, thac it is per- missible for the proprietors of the ' doss house ' to half poison their lodgers, and compel them to inhale an atmo- sphere which would be regarded as intolerable at any well- regulated sewage wharf." In almost all these houses men and women are herded together without any regard to U2 KNO^WLEDGE ♦ [April 2, 1888. morality or even decency, and numbers of poor children grow up in the midst of surroundings which will surely bring them to join the crowded ranks of the criminal classes. The School Board does not reach these children, and a lodger in one of the houses told Mr. Goldsniid that there was not a School Board officer in the metropolis who would "dare to show 'is ugly mug 'ere." The police inspectors whose duty it is to regulate these houses, visit them only during the daytime, when the lodgers have departed, order has been to a certain extent restored, and the fearful odours of the night have gone off; hence they gain no adequate ideas of the real state of afldiirs, and legis- late for what they do not understand. Mr. Goldsmid holds that the administration of the Lodging-houses' Act should be taken out of the hands of the Commissioners of Police, and that a company should be formed to supply clean and decent accommodation for poor lodgers. He suggests that blocks of the artisans' model dwellings, now being erected in all parts of London, should be arranged so that the rent could be paid nightly instead of weekly, that bithing conveniences should be provided, and that plain, wholesome food should be sold ready cooked on the premises at similar prices to those charged in coflee-houses. He believes that such a company should pay a dividend of 10 to 12 per cent., even if giving the best value for the money. The present common lodgingdiouse keepers, he calculates, make about 125 per cent, profit, wrung from their poorer brethren, whom they keep in a horrible condi- tion of filth, squalor, and degradation. Wo consider Mr. Goldsmid's suggestion a wise one, and recommend it to practical philanthropists. " Dottings of a Dosser " should be very widely circulated. THE FACE OF THE SKY FOR APRIL. By F.R.A.S. HE sun may be watched for the infrequent and insignificant spots whicli appear on his surface. The zodiacal light may still be seen in the west after sunset at the beginning o£ the month. Tlie aspect of the night fky is sliown on map iv. of "The Stars in tlieir Seasons." Minima of Algol (" The Stars in their Seasons," map xii.) will occur 1.5 minutes after midnight on the 15th, and at 9h. im. P.M. on the 18th, all other minima happening in daylight during April. Mercury is a morning star throughout the month, but rises such a little while before the sun that he is but indifferently placed for the observer — a remark which, )iiultitis mntandis, appHes equally to Venus. Mars will be in opposition to the sun on the Gth, and but for the fact that he has South Declination, would be well placed for observation. As at this time his disc subtends an angle of some 18", a consider- able amount of areographical detail may be made out with com- paratively moderate optical means. He is situated to the north-cast of Spisa Viiginis ("The Stars in their Seasons," map v.) Jupiter does not soutli until the early morning, but towards the end of April may be seen before midnight, though he is too close to the horizon to be at all fairly observable. Moreover, his South Declina- tion is so considerable that even when on the meridian liis altitude is too small to admit of the employment of a high power in viewing him. By the end of April his angular equatorial diameter will amount to 41-5". He is travelling from the south-west corner of Ophiuchus towards ^ Scorpii ("The Stars in their Seasons," map vii). As scarcely any certainl}' observable phenomena of his satellites will occur before midnight, we need not occupy space with them here. Saturn is travelling rapidly towards the west, and must be looked at as soon as ever it is dark enough. It will be noted that his rings have closed up to an extent such that his north pole is now visible. He is moving towards •>) Cancri and the Prsesepe ("The Stars in their Seasons," map iii.). Uranus will come into opposition to the sun on the 4th, .so that he is now in a fairly good position for the observer. He will be found about tliree diameters of the moon to the west of B Virgiuis ("The Stars in their Seasons," map v.), and may be at once distinguished from the surrounding stars by his bluisli unmistakable planetary disc, when viewed with adequate power. Neptune has disappeared for the season. The moon enters her last quarter at 4r3m. past noon on the 3rd, and is new at 9h. 7'7m. o'clock in the morning on the 11th. She enters lier first quarter 7'8m. before noon on the 19th, and is full at Oh. 221m. A.M. on the 26th. High tides may be expected about the last-named date. Three occultations only of fixed stars by the moon will occur at convenient hours during the present montli. The first will hai^peu on April 16, when X'- Orionis, a star of the Cth magnitude, will disappear at the moon's dark limb at 9h. 27m. P.M., at an angle from her vertex of 139°. It will reappear at her bright limb at lOh. 2Gm. p.m., at an angle of 300° from her vertex. Then on the 19th, 9 Cancri, of the 6th magnitude, will disappear at tlie dark limb of the moon at 7h. 34m. P-M., at an angle from her vertex of 70°; reappearing at her bright limb at 8h. 45m. P.M , at a vertical an,gle of 308°. Lastly, on the 22nd, B.A.C. 3837 (also a 6th magnitude star) will disajjpear at the dark limb at 6h. Um. P.M., at an angle of 90° from the moon's vertex. The star will reappear at the bright limb of the moon at 7h. 32ra. P.M., at an angle from her vertex of 173°. At noon to-day the moon is in Ophiuchus, through which she is travelling until 8h. A.M. on the 2nd, at which hour she passes into Sa.gittarius. Slie leaves S.agittarius for Capricornus (" The Seasons Pictured," plate xxi.) at 3h. P.M. on the 4th, and Capricornus in turn for Aquarius at 4h. P.M. on the 6th. Her journey across Aquarius is completed by 9h. P.M. on the 8th, when she enters Pisces ('• The Seasons Pictured," plate xxii.). It is llh. P.M. on the 11th when, in her passage over this great straggling constellation she reaches the northerly prolongation of Cetus, and an hour or two afterwards she has crossed it and emerged in Aries (" The Seasons Pictured," plate xxiii.). By 7h. 30m. P.M. on the 13th she has traversed the constellation last named and passed into Taurus. As she travels through Taurus she arrives ,at 7h. P.M. on the 16th on the western edge of the nortliernmost portion of Orion. E.xactly twelve hours later (i.e. at 7h. A.M. on the 17th), she crosses its eastern boundary and emerges in Gemini. Here she remains until 4h. A.M. on the 19th, when she crosses into Cancer (" Tlie Seasons Pictured," plate xxiv.). She is in Cancer until 6h. P.M. on the 20th, when she enters Leo. Her passage through Leo termin.ites at 7h. A.M. on the 23rd, at which hour she quits it for Virgo ("The Seasons Pictured," plate xxv.). At 3h. 30m. A.M. on the 26ch, her journey over the constellation last n.amed finishes, and she passes into Libra (" The Seasons Pictured," plate xxvi.). As she travels tlirough Libra, she arrives at 8h. P.M. on the 27th at the western boundary of the narrow northern spike of Scorpio, and when she has crossed this by 4 o'clock the next morning, it is to come out in Ophiuchus. She remains in Ophiu- chus until 3h. P.M. on the 29th, when, for the second time this month, she enters Sagittarius. There we leave her. By "Five of Clubs." MATHEWS ON WHIST. The Tenaoe. {Continued from page 96.) Hg^^^^HOUGH "tenace," or tlie advantage of position,* 1"""'"^'^ ; cannot be reduced to a certainty, as at piquet, and it is often necessary to relinquish it for more cer- tain advantages; stil), no man can be a whist- player who does not fully understand it. The principle is simple, but the combinations are various. If A has ace, queen, and a small card of a suit, of which li has king, knave, and another ; if A leads the small card, he letains tenace, and wins two tricks; whereas, if he plays the ace, he gives it up and makes but one. But if B is to lead, he has no tenace ; and lead which card he will, he * The word " tenace " has no connection, as many imagine, with the cards ten and ace in a suit, though it very often happens that the major tenace is actually constituted of these two cards. The word is a substautival form of the French adjective "tenace," tenacious, AoWi»r/, and implies the "hold "which the tenace gives over the suit. "Major tenace," or the first and third cards, gives the stronger hold ; but minor tenace gives a good hold too, in each case, though only if the holder of either tenace is led up to — when, with major tenace, two tricks are made, the second best card being held safe, while w-ith minor tenace, one trick is made, the third best card being held safe, wherever it may lie. The second best guarded, if led up to, is as good as the minor tenace. April 2, 188S.] KNOV/LEDGE 143 mail make one trick, and can make no more. The study of this easy instance, well considered, will enable the player, with some practice, to adapt it to more apparently intricate situations. The following case?, which happen frequently, will further explain the principles of the tenace: — Y is left with four cards and the lead, viz., the second and fourth trump, and the ac3 and a small card of a suit not played. Nine tramps are out. A, Y's left-hand adversary, lias the first and third trump, king and a small one of the suit of which Y leads the ace : what card should A play ? If A keeps his king he cannot possibly win more than two tricks : he should, therefore, play the king : for he thus brings it to an equal chance whether he wins three tricks or two. By placing the cards you will perceive, that if A's partner has a better card that Y's, Y cannot make either of his trumps, which, had E retained the king, he must have done. Y has three cards of a suit not played (the last remaining) viz , king, queen, and ten ; A holds ace, knave, and another ; Y leads the king ; if A wins it he gives up the tenace, and gets but one trick ; whereas, if he does not, he makes his ace and knave by preserv- ing it. A has ace, knave, and ten of a suit which his partner leads. If he puts on the ace, and his partner has no honour in the suit, he gives up the tenace, and can only win one. He should, therefore, play the ten (particularly if the lead is forced) ; for by this he pro- bably wins two tricks. It often happens that with only three cards remaining in his hand, the leader has the worst trump, and ace, queen, or some tenace of another suit. In this case he should lead the trump, to put the lead into an adversary's hand. By these means he preserves the tenace. This, though self-evident on proper consideration, is what good players never think of. Tenace is easily kept against your right-hand, but impossible, without great superiority of skill, against your left-hand adversary. You should not only endeavour to preserve the tenace, an advan- tage of position to yourself when it is evident that the winning cards lie between you and an adversary, but jou should do all in your power to give it to your partner, when you perceive that the strength in any suit lies between him and your left-hand adversary. In this case bear in mind that when the left-hand adversary or you lead, the tenace is against the adversary, whereas, if your partner has to lead, the tenace is in favour of your adversary. False Cabds. There is nothing more necessary to be explained to the beginner than what is usually denominated " nnder-play," as it is a constant engine in the hands of the experienced to use successfully against the inexperienced player. As an illustration of under-play — You return the lowest of yonr left-hand adversary's lead, though you have the highest in your hand, with a view to your partner's making the third best, if he has it, and still retaining the commanding card in your band. For instance, if A, fourth player, has ace, king, and a small one of his left-hand arlversary's lead, to under-p'.ay, he wins the trick with the ace and returns the small one, which will generally succeed if the leader has not the second and third in his own hand. You will see by this [putting yourself in the position of the player on whom this under-play is tried] that if you lead from a king and others, and your right-hand adversary, after winning with a ten or knave, returns it, you have no chance to make your king but by putting it on [assuming that your right-hand adversary is under- playing ; but even if he is not, his return of your lead would show your king probably worthless, a? it would indicate shortness in the suit, so that you cm lose little by playing the king]. The following is another situation for under-play : — A remains with the first, third, and fourth cards of a suit, of which he has reason to suppose his left-hand adversary has the second guarded; it he leads the fourth, it is often passed, and A makes every trick in the suit. [It is hardly necessary to say that the lead is not the first in the suit.] [This play is usually right if you are strong in trumps; but if you are weak, it is generally the best play to make your certain tricks as fast as you can, for the adversaries are probably strong in trumps, and therefore weak in some other suit, which probably is your strong one. Even in this case, however, if you are well protected in the other plain suits, the under-play indicated by Mathews is good ; for, if successful, it gives you good forcing- power in the suit, which will probably enable you to make the balance of its strength. If you gain but one trick in this way by a long card in the suit, it must be remembered that one trick made by " play " in a hand signifies an important percentage of ad- vantage. This is what weak players constantly overlook, not recognising the effect of good strategy unless three or four long cards in a suit are made against them. The sound player knows that one trick made by play in each hand would give him marked advantage, while one trick lost in each hand by bad play would signify crushing defeat in the long run. So great an advantage; indeed, cannot be expected from even the best play against the worst.] The term " ur.der-play " is now often, but incorrectly, used for all cases where a false card is played — that is, a card higher or lower than the one which would be played in accordance with normal whist language. The cases above considered are instances of under- play, except that in the detailed illustration of the first case the ace is played fourth hand from ace king instead of king as usual : this is "over-play," making the following "under-play" more effective, since the original leader of the suit would be apt to place the king anywhere but in your hand. What follows in regard to false cards relates to " over-play." Though it is certainly more regular ti win your adversary's as well as partner's lead with the lowest of a sequence, stiU I recom- mend occasional deviations from that maxim ; as it is of the greatest advantage to give your partner every information in his suit or your own, so it is often well to deceive your adversaries in their suits. It will now and then deceive your partner also ; but if done with judgment, it is, I think, oftener attended with gocd than bad effect. There are also other situations where it is highly necessary to deceive the adversary. For instance, Z, last player, has a tierce- major and a small trump ; a tierce-major with two others of a second suit ; king, and a small one of a third ; with queen or knave, and a small one of the fourth suit, of which his adversary leads the ace. It is so very material for Z to get the lead before he is forced, that he should without hesitation throw down the queen or knave as the most likely method to induce his adversary to change his lead. But this mode of play should be reserved for material occasions, and not by its frequency give cause for its being suspected. [This may be regarded as the earliest suggestion of the signal for trumps. If the adversary should not change suit, Z's partner on the faU of the small card would perceive that Z had played the high card to avoid being forced, and if he himself took the second trick would immediately lead trumps (his best, if short in trumps), precisely as in response to the trump signal of to-day. This way of indicating a wish for a trump lead belonged, however, to whist strategy, and was not, like the modern signal, a merely conventional arrangement, as little belonging to whist strategy as signalling by coughing, sneezing, or kicking under the table would be.] ( To he concluded.')

In an end game a good player shows to advantage. Both exact- ness and ingenuity are necessary to carry a difficult ending 1o a successful issue. Some players excel in one kind of end play, sucli as those involving br I iant sacriKces : ethers, again, are very good at pawn play. Probably the mo.-it useful knowledge is possessed by the placer who lias a knack of drawing games whicli seem to be lost for liim. It is beyond doubt an acquirement peculiar to some players more than others, and an experienced player will always take into his calculation the style of end game play of his opponent, and suit his play accordingly ; for to emerge with anything like an even ending against some players may mean to secure victorv, whereas with other players no advantage short oE a piece will secure an absolute win. The following two endings are ingenious examples how lost games are saved by drawing: — De. Smith. Black. ■WnrrF. Mb. W. Donisthobpe.

White replied by K to Qr, Kt to B5 K to B6 and the game was therefore abandoned as a draw.

In drawing the star-maps, which appear in Knowledge for March and April, I have lighted on peculiarities which have a singular bearing on an ancient record of a universal deluge long regarded as full of difficulties. A series of coincidences which are very strange indeed if they are merely accidental, points, apparently, in the clearest way to an interpretation w-hich is not indeed absolutely new (were it so I might find the evidence less striking), but for which certainly there has hitherto been no such evidence as that which I am about to suggest. I have had occasion of late, in dealing with the opening chapters of a book on Astronomy (now nearly a quarter of a centui-y in preparation), to consider the aspect of the stellar heavens as seen by Babylonian and Egyptian astronomers. So far as I know, no modern student of astro- nomy has been at tlie p:iins to pictui'e the starry skies as they appeared at particular long-past epochs in the history of astronomy. Here and there cases have occurred where some special star or constellation has been set back (as it were) so many thousands of years, in order to ascertain what position it had in the days of Ptolemy or Hipparchus, or, farther back still, in the time — some 2200 years B.C. — to which the buikling of the Pyramids of Egypt was first assigned by those who regard the descending passage as a polar pointer, or yet further back to that time — about 3-400 years B.C. — when the same star was in view down that descending passage, and when, according to Egyptologists, the dynasty of the Pyramid builders held sway over the land of Egypt. I have myself, accepting that remoter date as unquestionably the true era of Cheops, Chephren, and the rest of the Pyramid builders, noticed many details of interest in the stellar skies of those da)'s. I find, for example, that the ascending passage and the great gallery within the Pyramid, besides commanding (by reflection at a water surface) the pole-star of the period, bore directly on the star Alpha (Jentauri, remarkable as the nearest of all our sun's fellows in the star depths. The long trenches dug outside the eastern edge of the Pyramid's base (and called by Professor Smyth the azimuth trenches) bore on the bright stars Arcturus and C'apella at their rising, and were doubt- less associated with the observation of the rising of these stars, so as to be visible just before sunrise — a relation called the heliacal rising of these first-magnitude stars. The Pleiades were at that time exactly on the equator, a much more critical and interesting feature than Professor Smyth had looked for when he sought a date near the year 2200 B.C., and selected one which put the Pleiades on the meridian passing through the sun's place at the spring equinox — for the equator is of all the circles on the celestial sphere the most easily recognised and the most obviously interesting. But while I had noticed many such points as these, and had indeed been much attracted by their study, I had not been able to find time for what I had long intended — the construction of maps which should show tlie whole of the starry heavens a.s they would have appeared at or about tliat critical time when the astronomy of the ancient Babylonians and Egyptians (as distinguished from the modern Nebuchad- nezzars, Pharaohs, and the rest) reached its culmination. No astronomer who studies carefully wh.at is known about ancient astronomy, can fail to recognise in the astronomy of the later Chaldeans the signs of decadence and degenera- tion. Nor can we wonder that it is .so. Clearly in tiie days of the earlier kingdoms of Babylon and Egypt, astronomy had been regarded as full of material promise. A 11 the ancient astronomers wei'O astrologers : it was the astrological aspect of astronomy alone which had invited them to the laborious and expensive works by which they had hoped to force from the skies the secret of the stars, and to give to their ruling dynasties the power not only of reading but of ruling the celestial orbs. That hope had been in great measure disappointed. Astronomers still from time to time renewed their aspiration.s, and we find records that kings and rulers put trust in the promises of their astrological magi and diviners; but never again did whole nations contribute as they had done in the days of Cheops and Chephren, and in those of the builders of the Babylonian temple of the planetary spheres, to erect temple-observatories for the study of the movements of the heavenly bodies. The building of the Great Pyramid and (contemporaneously with it) its fellows in the Ghizeli plains, marked the time when astrological astronomy reached its highest j)liase of development. It was at once the science and the religion of the great Eastern nations of those days. Cities were built to the sun and moon. All the works of human life, fiom the day when the babe's nativity was cast to the time when the body was to be committed to the tomb, were regulated by the movements of the heavenly bodies, whose influences as deities were sujiposed potent over all transactions from the most trivial to the mo.st important. When leisure, or rather the course of my literary labours, gave me the opportunity to construct a planisphere' of the ancient skies, I took for my epoch 3400 years b.c, because while that accorded well witli the date assigned by Egyptologists to the reign of Cheops, it brought the pole- star. Alpha Draconis, or Thuban, into the direction aimed at by the long descending passage, cut (some four feet squai'e) into the solid rock below the Pyramid, and con- tinued right through the massive stonework to a total distance of more than a Jiundred yards. It has always seemed to me preposterous to question the astronomical significance of this ])olar pointer. One might as reasonably question the astronomical use of the monster sundials and other shadow-throwing structures in Delhi, Benares, &c. — as, indeed, non-astronomical persons would most certainly do if we did not chance to have records of the objects with which these masses of stonework were .set up, and of the astronomical uses to which they were applied. The men of the Pyramid times may not have made such advances in science as the men of our own day, but they were not wanting in sense. We may be sure they did not make these obviou.sly astronomical passages and galleries merely to symbolise imperfectly for after ages such knowledge as they possessed, but with a very definite purpose. We may confidently accept as obvious the theory, first advanced by Sir John Herschel, that that long passage was a polar pointer, the longest and most massively constructed ever m.ade by man. We can have no doubt that Thuban, the mid star of the Dragon, was the pole-star towards which it 146 ♦ KNOW^LEDGE ♦ [May 1, 1888. was diiecteJ. This leaves us only two dates between which to choose, for the time of the important astronomical era marked by the building of the Great Pyramid — viz. about 2200 B.C., and about 3400 B.C. — unless we care to go back some 27,000 years farther, when again we find a pair of dates, about 31,000 and 32,200 years B.C., when Thuban was rightly situated. We may safely reject all such exceedingly remote dates, however, as Egyptologists agree in assigning to the dynasty of Cheops, C'hephren, &c., dates between 3200 and 3600 before Christ. For the date 3400 b.c, then, I construcled my charts, expecting to obtain interesting and curious results. I hoped in particular to find explanations of references to the stai's by poets of later days, who recalled old sayings in ignorance of the fact that the aspect of the heavens had altered since those sayings had been in vogue. For experience shows that there are few subjects in which old ideas retain their influence more tenaciously than they do in regard to the aspects and movements of the heavenly bodies. The first glance at my maps (when they were completed in such sort that the skies of 5300 years ago were presented before me) served to explain several familiar passages of the clas.sics. For instance, Virgil's well-known lines, Candidus aurati.s aperit quum cornibus aiiLum Taurus, imply as distinctly as possible the idea that the year began (which would mean that the sun crossed the equator at spring) when the sun was on the Bull's horns. But in Virgil's time, the sun was not in the constellation of the Bull at all when the year began (in the old sense of the words). The point where he crosses the equator had passed out of Taurus, over Aries, and had already entered Pisces at that time. The sun in Virgil's age was passing over the Bull's horns in the middle of May, a time which cannot by any astronomical or meteorological artifice be regarded as the opening of the 3-ear.* But in my chart for 3400 b.c, the sun was right on the Bull's horns at the beginning of spring. Another passage in Virgil finds an explanation from the same chart. In his "Pollio," taken from a Siliylline prophecy of venerable but unknown antiquit}', we find him saying. Jam redit et Virgo, redeunt Saturnia regna, as if there were some connection between the constellation of the Virgin and the return of the beneficent influence poured forth by the sun in summer. Pope, indeed, in his introduction to his eclogue, " Messiah," goes so far as to draw a parallel between this ))assage and the well-known passage in Isaiah, " Behold a A^irgin shall conceive and bear a son." But without entering into a discussion of the Virgin birth attributed of old to sun-gods, Osiris, Horus, * I may remark here that Chaucer is more careful in this matter, but has been blamed by Tyrwhilt for an error which he had not made. In the prologue to the " Canterbury Tales," he speaks of the time (which he there indicates as ia April, and in other places marks as late in April) as that When Zephyrus . . . with his swoote breath Inspired hath in every holt and heath The tender cvoppes, and the yonge sun Hath in the Ram his halfe course y-run. On this Tyrwhitt remarks that this would place the time of the pilgrimage in the end of JIarch. But Tyrwhitt lias confounded the sign with the constellation. Our almanacs speak of the sun entering Aries on the day of the autumnal equinox, meaning the sign, winch for convenience still has its " iirst point " at the place where the sun crosses the equator. But the sun does not really enter the constellation of the Ram till a month later. Chaucer, who seems to have been well versed in the astronomy of his day, says rightly that the sun had run half his course in the Kam towards the end of April. Mithras, Serapis, Adonis, and the rest (and naturally ascribed later to such teachers as Zoroaster, Gatitama, Plato, and others), we may at once find an explanation of Virgil's reference when we note that at the time to which all his astronomical passages must be referred, the sun — who was leaving Taurus in spring — was entering Virgo at mid- summer. I might consider a number of similar matters, many of them of much interest, but that I should thus leave little space for the special discovery which I wish here chiefly to consider. Tlie celestial eqttator drawn for the year 3400 B.C. runs along the whole length of Hydra, the great sea-serpent, from his Heart, marked by the star Alphard (or the Soli- tary, known also as Co?- Ilydrm) to the tip of his tail. The head and neck are reared above the equator, that is, on its northern side, which for Egypt and Babylon would of course be above, and the two small constellations, the Raven and the Cup, which, though undoubtedly very ancient, were as undoubtedly parts of the Sea-serpent as well as inde- pendent constellations, rise above the equator, as if the body of the Sea-serpent showed here slightly above the ocean level. This peculiarity of the starry skies of the time we are considering, recalls the old idea that around the heavens as around the earth is coiled a mighty serpent, associated with the ocean waves surrounding the frame of the earth. In the description of the constellations in the shield of Herakles we find (following Elton's translation) what corresponds closely with this peculiarity :■ — • Rounding the utmost verge the ocean How'd As in full swell of waters, and the shield All variegated with whole circle bound. Remembering that the same poem describes the Dragon as " coil'd "— . . . full in the central field, With eyes oblique retorted that askant Cast gleaming tire, which corresponds precisely with the polar position of the Diagon at the time we are considering, we see that the rounding of the utmost verge by the ocean " swell of waters " may fairly be regarded as extremely significant. It matters not in the least whether we adopt or reject the idea, thrown out Ijy me eighteen years ago, that the original description of both the shield of Herakles and the shield of Achilles (two unquestionably solar heroes) related to the dome of a zodiac temple for the worship of the sun. It suffices that in each case the poem speaks definitely of the constellations. Each shield contained them, so that the object originally described undoubtedly presented the constellations as on a dome or hemisphere, or in a chart, and my sole contention here is that the reference to the Dragon as the polar constellation, and the sea waves as bounding the circuit of the constella- tions, indicates the period to which the picturing of the constellations belonged. In passing, however, I may remark that the identity of many lines in the two descriptions shows that in each we have part only of what was originally a much longer poem ; and, while it is unlikely enough that objects like the constellations would be selected for the adornment of a warrior's shield, and improbable that in a grottp of songs like those composing the " Iliad, ' so long a description would be devoted to a mere shield (unless a poem already extant provided convenient material), it is utterly incredible that a poem so long as the original from which both " shields " were deriveJ, should ever have related to such a subject as a mortal warrior's shield, or have been but part of a single book of an epic poem. The shield of Jove himself in the " Iliad " is described in four lines ; the poem from which the shields of Herakles and of Achilles May 1, 18SS.] ♦ KNOW^LEDGE ♦ 14; have been borrowed cannot have been much less than a thousand lines in length. It was the recognition of the peculiar correspondence be- tween the equator and the long body of the Sea-serpent (ranging past the zodiacal constellations, the Crab, the Lion, the Virgin, and the Scales) which led me to inquire into the position of some of the most remarkable constellations of the earliest known systems of astronomy. Naturally I turned first to the great constellation Argo, which is, or rather was, altogether the most striking of them all. Let me, however, premise that few even among astronomers seem to understand how in ancient times the constellations were dealt with. It requires a long and careful study of old descriptions and old globes and pictures, to recognise what the constellations re;illy must have been ; and modern astronomers, those at least who are chiefly engaged in sur- veying the heavens, take little interest in inquiiies of the sort, ilost of them imagine that the constellations have always had about the limits assigned to them in modern charts. And since it is obvious that, as thus defined, the star groupings show for the most part very little resemblance to the various objects after which they are called, it is quietlj' taken for granted that men in old times called the star groups by names assigned for the most part in quite arbitrary fashion. Mr. Lang, in his interesting volume " Custom and Myth," has an essay on star myths, which is partly based on the idea that there is no real resemblance in most cases between a constellation and the object after which it is named. " The most eccentric modern fiincy," he says, " which can detect what shape it will in clouds, is unable to find any likeness to human or animal forms in the stai-s." Yet the forms are there in the star-groupings, in some cases so strongly sug- gested, that once noted they cannot readily be lost. Mr. Lang himself notes the Crown, where the resemblance is obvious when the heavens themselves are studied, and also easy when the modern constellation-maps are considered. The Dolphin is another example where the fitness of the ancient name is easily .=een. A case or two of this kind ought to suggest that, in other cases, where the resemblance may not appear so obvious, and where there may be no resemblance at all when the modern constellation is exa- mined, either some important changes have taken place among the stars themselves or else the modern constellation differs gi-eatl}' from the old one. Eejccting the former supposition as contrary to the evidence — for though stars have changed in brightness there is no evidence of changes numerous enough to spoil the old constellations — we examine the other. But here at once we fi^nd how the difiiculty has arisen. The modern constel- lations not only differ from the ancient ones, but have been formed on an entirely different plan. The old constellations overlapped freely; the modern ones, on account of the special purposes which they are intended to fulfil, fit like the counties in a map of England. The care with which this requirement is now attended to belongs in reality to quite recent times, though probably even in the days of Hipparchus and Eudoxus something of the sort had been attempted. There are clear signs that even long after the Greek lettering of Bayer was adopted, the constellations remained somewhat overlapping. Thus the star which Bayer called Alpha Andromeda; he also called Delta Pegasi, as it formed an essential point in the configuration of both constellations. But as the modern astronomer does not care two straws for the mere configuration of the constellations and cares a gi-eat deal about simplicity and uniformity of nomenclature, one of these names had to be given up. Consequently the modern student of the stars looks in vain for Delta Pegasi in the charts. lie finds Alpha, Beta, and Gamma, also Epsilon, Zeta, Eta, and so on, nearly to the end of the alphabet ; but Delta Pegasi he cannot find. Yet the star which was so named is of the second magnitude. In like manner the constellation Auriga wants the star Gamma, which formerly marked the spot where Auriga overlapped Taurus. The star remains, of course; but it now only has one title. Beta Tauri, instead of being called also Gamma Auriga^. In modem charts, showing the constellations, we find lingering traces of the old iisage, carelessly though these figures have been dealt with. Thus the Scorpion's claws had been for too long a time and too intricately mixed up with the legs of the Serpent-holder to be readily extricated. By a desperate efibrt the constellation boundaries have been kept apart, though both Scorpio and Ophiuchus have lost stars in the contest. But the figures showing these two constellations still present one claw of Scorpio amicably twined round one of the Serpent-holders legs, the other extending behind the southern scale of the Balance. It may be noticed in passing that the Scorpion and the Balance illustrate the change from the ancient method in another way. It is well known that for a time the Balance disap- peared from Greek star maps, notwithstanding its impoi-tanc* as a zodiacal sign, and its exceedingly ancient standing. Then the claws of the Scorpion were withdrawn and the Scales resumed their place, many imagining that the Balance then first took its place in the heavens. But this is an altogether mistaken position. They merely resumed the place which they had formerly occupied. Now when we are no longer limited to the modern con- stellation outlines, in our search for the star-groupings in which men of old found resemblances to various objects, animate and inanimate, we can readily see where these resemblances were imagined. For instiince, whereas the present Lion of the star maps, is an altogther feeble creature, with a nose like a rat, and no tail at all, the ancient Lion, whose head was on Cancer, its mane over Leo Minor, and the tail formed by the group called Berenice's Hair, while his hindpaws fell on the Sextant, and his forepaws over the Sea-serpent's head, was really a magnificent stellar animal, whose form can still be clearly recognised among the stai's. So with the Bear : where our maps show his long tail — imagine a long-tailed bear and what the ancients would have thought of our raising such a nondescript to the heavens ! — fell really the outline of a portion of his back. A large part of his body covered that ridiculous modern constellation, the Hunting Dogs ; his head for a wonder has been left, and most neatly pictures the peculiar head of .a bear (though it also served the Egyptians for the head of a hippopotiimus), while the long plantigrade paws are also most characteristi- cally indicated. He is chased, this real old Bear recognised by all the nations of antiquity from China to Peru (the long way round), by the Herdsman Bootes, with uplifted arms : so, at least, the old watchers of the stars saw the figure of the Ploughman ; but modern astronomers have thought it necessary to deprive him of his right arm, which has been assigned to the constellation Corona. By modern astro- nomers in this case, I refer to the contemporaries of Hipp.archus and Ptolemy. And so with many others of the most interesting of the ancient constellations. They have been separated where they formerly overlapped. Then pieces have been taken off them to form such ridiculous con- stellations as the Clock, the Painter's Easel, the Pneumatic Pump, the Flying Fish, the Chameleon, the Shield of Sobieski, and ahost of other absurdities which discredit the memory of Hevelius, Lacaille, and others who, like them, should have known better.

For instance, in a recent issue, a Newark (N.J.) authority (?) gives the modus operandi for catching and killing thf saurian, when its skin is wanted. One method was to get tbe 'gator amused at some side-splitting (New Jersey ?) tiile, or else tickle him under the fifth rib, and when he opened his huge mouth in an amused grin, to seize tbe opportunity and thrust a big harpoon through his tongue. The 'gator would then good-naturedly butt himself against the bank until be felt the throes of final dissolution, when be would float up against the wharf, give up the ('gator) ghost and be in readiness to be skinned. Again, the spectacle of " Alligator Piatt " riding on a 'gator's back, " geeing and hawing," so as to make a good landing, would make even the most ill-natured and fierce bull saurian that ever in- fested these waters, split his sides with loud guflaws ! It should have been added to this that he trained them and drove them in pairs to plough his orange grove 1 The 'gator is beset witli dangers from tbe first, which probably accounts for his somewhat unfriendly disposition. 'The female finds some secluded sandbank exposed fully to the sun's rays, scoops out a hole two or three feet deep with her fore paws, lines it with old rubbish, grass, &c., and lays a layer of eggs from 2.3 to 200 at a time. These are care- fully covered over to a height of three to four feet with grass, small sticks, &c. From the moment of laying tbe eggs scores of enemies are in wait. The big sand cranes and eagles are not averse to a good meal of 'gator's eggs, while bears, wild cats, and foxes take them as a great delicacy. Then comes the naturalist and curiosity hunter, and hundreds of eggs are gathered by these insatiable seekers. The old female is very fierce at this time, and lies in wait near by, and has been known to attack men even in the defence of her nest. Finally the young 'gators are hatched by the sun's rays, and the mound seems alive with what looks like young snakes. These young ones are smart and lively from the first. The old bull 'gator, with an idea of the good things of life, has been taking a sly intei'est in this incuba- tion, and when the young ones got out he is on band to take a good meal on infant alligator. Many fights have been witnessed between the female and the nuxle, in the former's defence of her young. The young ones, until they reach a length of a foot, are with the old female all the tiuie. Their great delight is to lie basking on the sunny sand bank, clustered in one big mass. Upon the slightest alarm the old mother utters a hoarse call, opening wide her capacious mouth, and the youngstei'S scramble in for safety. Formerly they were plentiful on all tbe streams and lakes in this State, but the iudisciiminate shooting has scared them off into the more inaccessible bayous and lakes. In tlie lower portion of the State, in the everglades, they are hunted vigorously for their skius. Scores of hunters secure from ],0tlO to 1,.')00 skins annually, and as they receive f^l each for them, they obtain what is to them a princely income. " Alligator Piatt," one of the oldest hunters in that section of the State, lives on Lake Tohopekoliga, and his .■•tories of miraculous escapes from 'gators and boars aie tlioroughly enjoyed by the touri.sts who have the good fortune to hear him narrate any of them. * Jacksonville (Fla.) correspondence St. Louis Glabe Democrat.

URING the present approach of !Mars, who passed opposition on April 11, careful ob- servations should he made by those who possess large telescopes, or have control of well-provided observatories, on the so-called "canals" of Schiaparelli, and especially on the duplication of the canals. The planet will b3 more favourably situated than Schiaparelli himself supposes for the investigation of these phenomena. He recog- serve to show observers of Mars that whatever may be the accuracy of Schiaparelli's observations, he has not correctly delineated the planet's aspect, while it will equally show students of physical geography and believers in the uni- formitarian views now prevailing throughout science gene- rally, that the "' double canals " have probably no objective existence. Yet we cannot reject Schiaparelli's observations, renewed as they have been by himself at successive oppositions of Mars since the phenomenon was first observed, and confirmed by Celoria, Perrotin, and Trepied. I suppose Schiaparelli himself has given up the wild notion suggested by him, and accepted by several of the ultra-cautious astronomers of the inductive school (in which r.ashness and caution strangely interchange places), that the can.als and their duplications are the work of Martian inhabitants. For though a purely inductive philosopher (acting on the inductively cautious principle that every- thing observed is to be accepted precisely as observed, and not to be corrected by any such rash process as deductive analvsis) might gladly accept the idea that Martian beings could first construct canals thousands of miles long and twenty or thirty miles wide, and then duplicate these in two years or so of terrestrial time, even inductive caution can scarcely be capable of believing that the second canal of each pair would be destroyed as each i\Iartian summer approached and renewed soon after the next following spring. The interpretation which, with deductive r.ashness, I suggested for Schiaparelli's observations soon after they were first announced seems so strikingly confirmed by his later Fio. 1.— Chart o£ ilars by Signor Schiaparelli, showing his double canals. ni.ses in the appearance and disappearance of double canals a periodicity depending upon the Martian seasons, having observed that they come into view soon after the vernal equinox of the northern hemisphere, and gradually dis- appear— that is, fewer and fewer of them are seen — towards northern midsummer ; and he has invited astronomers to observe whether similar phenomena are to be noticed after the autumnal equinox of the northern hemisphere — that is, after the vernal equinox of the southern hemisphere. But he does not notice that there is reason to expect a recurrence of the phenomena which have perplexed him (and by which he has perplexed many) as the autumnal equinox of the northern hemisphere approaches — and under more favourable conditions than after the equinox, because most of the " canals " are in the northern hemisphere of Mars. Fig. 1 i-epresents Schiaparelli's chart of Mars on a modification of Mercator's projection. A glance at it will observations and the recognition of a seasonal periodicity in the phenomena, that I venture to recall attention to it now, when it can be tested by observations which may prove even more effective, if not decisive. " Some difference of opinion," said the late Mr. Webb, " may possibly be expected concerning the.se strange appearances" — a tolerably safe prediction — "and the consequent enfeebling (to say the least of it) of the long-admitted terrestrial analogy m.ay be, ^ to some minds, unacceptalile." I have one of those " minds," a mind which obstinately declines to give me the otium cum dijnitiite resulting, so far as I can judge, from the placid acceptance of strange observations as signifying just what they seem to signify, and not at any price to be interpreted according to known laws and established analogies. " But," Mr. Webb went on to say, " the established reputation of the observer " — Schiaparelli — " demands at any rate a respectful attention to his statements." With this opinion 150 KNOWLEDGE ♦ [May 1, 1888. I must express the fullest agreement : only, it has always seemed to me that when an observer of established reputa- tion has made a series of striking observations, respectful attention involves careful examination of his work. If I were myself devoted to observation, and \mable (as is the case with many of our best observers) to give much time to analysis, I should not be very grateful to those who claimed the acceptance of my observations precisely as they stood, without inquiry into their significance, or such due com- parison intei- se and with observations made by others as would be essential to their satisfactory interpretation. To this I may add that the basis of such analysis should always, in my opinion, be admitted analogies. I know of no theoi-y now accepted as sound which ever had any other foundation. I regard Schiaparelli's observation as one of the most interesting ever made by the telescopist. At the same time, I consider his " double canals " as having no existence in nature. " But," says the purely inductive philosopher, " he has seen them, and therefore they must be objective realities." Hevelius said the same of the star-discs which his telescopes showed him, and became quite angry (for an astronomer) when his measurements of those discs were Fic. 2. — Construotiou for determining tlic axial pose of Mars on tlie meridian, Jlay ], 18S1. lookeA on with doubt. If his telescope had been a little better he would have seen not only seemingly well-defined and measiu'able star-discs, but a series of very obvious and unmistakable rings round each star. And probably the more simply inductive philosophers of his time would have been indignant (philosophically, of course) at those who would not admit the enfeebling, to say the least of it, of long-admitted solar analogies, and give such respectful attention to the observations of the eminent astronomer as would have been involved in the supposition that other suns than ours have immense rings round them, so situate through some strange influence that they are none of them foreshortened, but all appear exactly circular. The interest of Schiaparelli's observations resides (for me) in the circumstance that they indicate the existence of an analogy between Mars and the earth, which, though long suspected, had never before been demonstrated. Unques- tionably not duplicate canals on Mars, nor phenomena due to our own atmosphere, the double marks were as unques- tionably seen ; and we need not bo in a hurry to say that " explanation is set at defiance," since there is nothing suggestive of inherent inexplicability in these appearances. On the contrar}-, we seem guided easily towards an inter- pretation which promises to remove every ditticulty. Parallel lines apparently seen where no parallel lines can be reasonablj' supposed to be, suggest certain optical phe- nomena in which we see parallel lines as the optical images of lines really single, circles as the optical images of points, and other optical products — as they may be called since they are not optical illusions — which by no means correspond with the real nature of the object under obsei'vation. The optical image of an exceedinglj' fine bright line on a rela- tively dark ground observed through a telescope is a broader bright line, on either side of which run two parallel lines much less bright, and outside these again other still fainter lines. Under particular conditions of relative lustre in the source of light the eye would recognise only the two rela- tively dark parallel bands on cither side of the median bright streak of measurable width (depending on the aper- ture of the telescope employed). Is it not, on the whole, more likely (to say the least of it) that what Sohiaparelli has taken for sets of double canals are simply the two relatively dark streaks on either side of the bright diffraction images of exceedingly fine luminous streaks on Mars, than that those objects arc really "double canals" on toe enormous scale imagined, or that the Fio. 3.. -Meridians atid lalitude-pamllels of Mars rn the meridian, May 1, 1888, for an inverting telescope. phenomena are otherwise wholly inconsistent with " admitted terrestrial analogies 1 " The varying aspect of these objects would be readily explained on this supposition, nay, wculd be a necessary consequence of the hypothesis that the luminous streaks ai'e Martian rivers. Moreover, the change of ajipearance would be likely to occur at precisely the season when Schiaparelli has found that it does occur. Rivers on Mars would be fivr too delicate objects to be seen with their own proper outlines even with the most powerful telescopes, whether they were bright streaks on a darker ground or dark streaks on a lighter ground. It is not likely that there is any river so large as the Nile, probably there is not one so large as the Danube or the Volga on the ])lanet Mars, and a river would have to be at least twenty times as wide as the Nile, taking the average of the lowest five hundred miles of its flow, to be seen with the telescope at Mars's distance. Usually a river if visible would be seen as a dark streak on the lighter background of the continent, just as the Martian seas are usually darker than the lands. Such a river would be perceptible, though not actually visible with its true outlines, through a good telescojie, as a dusky streak many times broader than the river itself. But May 1, 1888.] ♦ KNO\VLEDGE ♦ 151 if under special atmosplieric conditions there were mists over the waters of the river, or the river being frozen remained snow-covered in spring after the snows liad melted from its shores, the river would be bright on a darker back- ground, and then the difTraction image of the river would appear as a broad band of light between a pair of parallel dark streaks. At other times the river would not be seen at all, the continent with its rivers being more or less enshrouded in cloud and mist. It seems reasonable to suppose that (1) during the winter months of the northern hemi.'^phere the rivers on Mars would not be visible, or would at least not be conspicuous ; (i) after the vernal equinox the clouds and mists hiding the continents and rivers in great part from view would melt awav, but would linger longest over the river beds ; and (.3) as summer approached the mists would melt away during the midday hours over the rivers also. The observations of Schiaparelli, as I have endeavoured to interpret them, correspond with this sequence; for (1) in the winter of north Mars no dark streaks are seen, or but few, and those indistinctly; (2) in the spring are seen the parallel dark streaks ; and (3) towards summer the duplicated streaks become single. Now during May, June, and July, ]\lars will be passing through the late summer and autumn of his northern hemi- sphere, and it will be interesting to inquire whether the dark single streaks, indicating clear skies over the river beds of Mars, change again into the dark double streaks indicating mist along the river tracks, before passing as winter advances, under those envelopes of mist and cloud, which will hide the rivers altogether from our view. I give in fig. 2 the construction for determining the posi- tion of the polar axis of Mars, and the opening of the equator on May 1.* From that date onwards the planet's presentation will not differ importantly while the planet is favourably situated for observation, so that fig. 3, the pro- jection for the inverted telescopic aspect of the planet (on the meridian) will serve well enough to the end of this Martian season. WEIGHING THE EARTH. (Concluded J'rom. pcuje 12-3.) yS-O jijiiiSSjyi HE principle of the method is Olustrated in fig. 1. Here a and h are two small globes at the ends of a uniform rod r r' , suspended in a horizontal position by the cord or wire c C, attached to its centre C. The horizon- tal rod, left to itself, tends to a mean posi- tion which may be called the position of rest, though, as a matter of fact, when the suspension is as delicate as it has to be in the experiments considered, the rod never is at rest, but oscillates constantly, and very slowly, through short arcs on either side of its mean position. A and B are two heavy globes, which can be brought readily into such positions as are shown in fig. 1, where their attractions tend to draw a and h towards them in the direc- tions shown by the arrows. The result of these disturbing influences is to sway the rod r ?•' from what had been its position of rest, when undisturbed, to some new position of rest, as n n' or m m', about which it oscillates as before. The processes of observation are as follows : First, the time of oscillation of the undisturbed rod Ls noted, to ascertain the force of torsion which has to be overcome to produce a given displacement. Then, the large globes being brought up to such positions as A and B, their distance * See Knowledge for February 1, 1S84 (vol. v.), p. 71, for an account of the simple process to be followed in all such cases. from the positions of rest of a and b when these were undisturbed is carefully measured, and the new position of re.st taken up by « and b is ascertained, the times of oscillation being noted throughout, so that any change in the torsion may be recognised and taken into account. This having been done, the globes A and B are removed to the mean positions M, M', and the balls a and b are allowed to return to their position of rest. Then the globes A and B are carried round in the same direction until A is close by b on the left, and B close by a on the right, when their attractions tend to displace a and b in directions contrary to those shown by the arrows : the position of rest of the rod r >■' is next ascertained (the times of observation being throughout carefully noted) as before. From these observa- tions, the attractions of the globes A and B on the balls a and b (or b and a) can be determined, since the times of oscillation indicate the torsion, and the position of rest determines how much of the torsion is overcome by the globes' attraction. By calculating next what the attraction of either globe would be if, instead of being at its measured distance from the neighbouring ball, it were at the earth's centre, and comparing this with the known attraction of the whole earth, we can ascertain how much the whole mass of the earth exceeds the known mass of the leaden globes : in other words, we can ascertain the mass of the earth, and Fig. .,.-•' M' 1. — Illustrating the Principle of the Cavendish Experiment. (Baili/.) therefore — its volume being known — we can determine its mean density. Cavendish, near the end of last century (" Phil. Trans.," 1 798). applied this method in a form somewhat simpler than that described, but depending practically on the same prin- ciples, deducing a mean terrestrial density of 548. Hutton, re-examining C'avendi.sh's experiments, reduced the deduced density to 5 32 ; but many prefer Cavendish's own treatment of his observations. The experiments made by Cavendish were not very numerous, neither were those of Reich, of Freiberg, who in 1838 deduced by the .same method a mean terrestrial density of 5 '44. We must attach much more weight to the ex- periments made by Francis Baily in 1838-42, since they were not only conducted with singular care and caution, but were obtained in many diflerent ways (though, of course, all by the same general method) and by a ver}- large number of experiments. It will be well to give a few details respect- ing Baily's work, that the trustworthiness of his estimate of the earth's weight may be fully recognised. The rod rr', fig. 1, of 6.'f feet long, was of light wood (in nearly all the experiments), and was suspended in various ways in the different experiments, viz., on single copper wire •0178 inch and '0219 inch in diameter; on two parallel iron wires 0'177 inch, 0367 inch, and 0'415 inch apart; on two brass wires 0-380 inch and 0'415 inch apart ; and on two silk fibres 0177 inch, 0-307 inch, 0380 inch, and 0-415 inch apart. At the ends of the rod were attached balls of dif- 152 ♦ KNOW^LEDGE ♦ [May 1, 1888. ferent material and size in diffe:-ent experiments, viz , H-inch platinum, 2-inch ivory, 2. inch glass, 2-inch zinc, 2-inch lead, 2.Viuch lead, and 2.\-inch brass. In a small number of experiments (fifty-six) the wooden rod was replaced by a brass rod without balls. The torsion rod and its suspension were enclosed in a case with a glass at one end. The devices by which the effects of electricity, magnetism, radiation, and other disturbing iniiuences were as far as possible eliminated need not be described, u9r the multitudinous experiments considered by which explanations of irregular discordances were sought for or corrections introduced. Nor is it neces- isary to describe or picture Baily's instrument either as a whole or in detail — the general principle of liis method, already sufficient!}' explained, being all that ij wanted and all that the student really needs to understand. Let it suffice to note that the experiments for the correction and explanation of discordances were more numerous than those actually employed for the determination of the earth's mean density. The experiments thus used amounted in all to 753. Of these, however, 5(i, above-mentioned, when only a brass rod was used, were not seriously intended for the determination of the earth's mean density. They are well described by De Morgan as " a defiance to the apparatus to fail if it could." Yet they indicated a mean density below (5 — a result much nearer the truth than the Harton Colliery experiments had given, costly and complicated though they were. The remaining G97 experiments gave results ranging from 5") to •5'8-t7. The mean value deduced by Baily (due weight being given to each set of experiments) was 5'G6. Cornu, in 1872, applying the same method with improve- ments suggested by recent scientific developments, obtained the value 5'56. He did still better work in applying to the more numerous experiments of Baily, as recorded, correc- tions justified by recent physical discoveries. He found that as thus corrected Baily's elaborate and beautiful experiments indicated a mean earth-density of 5 '55. The following table presents the results of the application of Michell's method : — Cavendish 5--I8 „ (revised by Hattcn) . . . -. .5 32 Reich . . .

Taking the eai'th's mean density at 5 '55 times the density of water, the earth's mass=59b,(J54,000,000,OUU,000,000 tons. The earth's equatorial radius contains in round numbers 20,926,200 feet, the polar radius being . J^ less, and 35-943 cubic feet of water weigh one ton. Hence, the earth's mass, expressed in tons, which when duly worked out (the use of logarithms will greatly help the reader who cares — as every reader should — to test the calculation) gives the above value. There is a method by which, I think, the mass of the earth might be directly compared with that of a known mass of lead or other heavy metal, without the difficulty arising from the varying torsion, under varying conditions, in the Michell method. The plan suggested (but in an unwork- able form) by Professors Richer and Mayer, of the Berlin Universit}-, will be readily understood from figs. 2 and 3. A B D is a globe of lead, which might be three or four feet in diameter, whose centre is at C. At M, the highest point of this globe, a small .steel block is set, on which rests the knife-edge c of a balance a c h. The large globe A B D is pierced along the vertical directions AD and BE, imme- diately under the extremities n and h of the baUvnce-arms c a and c b, in such sort that the balance can be u.sed to weigh bodies either above A B or below D E, or one above A B and the other below I) E, as in the case illustrated in fig. 2, where a weight lu above A is weighed against a (t)- s>, Fifj. 2. Ilhistrating a plan suggosted for weighing the earth directlj- against a globe of heavy metah weight w' below E. Fig. 3 .shows the balance on a larger scale, and illustrates the arrangement suggested as best for applying the weights. Immediately above the centre- piece c (the knife-edge of which rests on the liorizontal surface k I at e) is a thin ])late of polished steel which, when the balance is level, has its plane at right angles to the then horizontal direction a b. A horizontal beam of light from a distant source, situate either on the left or on the right of the apparatus as pictured, falls on this steel mirror, and when the balance beam is level returns after reflexion upon its horizontal track, but when the beam is inclined the return ray is inclined to the horizon. Thus the reflected ray ]iractically serves as a very long index by which to measure the deflection of the balance. [In the actual experiments the light could be sent out and received as in the observations for determining the velocity of light by Fizeau's and Wheatstone's methods.] Two weights exactly equal and similar suffice for all the experiments, but pre- ferably four sliould be provided, so that in any set of experi- ments there need be no occasion to transfer a weight from above the large globe to below or via versA. It would be desirable also that sets of weights of different materials should be employed, so that diversities depending on the physical qualities or inter-relations of different substances might be eliminated. The weight-holders are shown in fig. 3 at ;), q, J) , and q . Their construction should be such that with the least amount of disturbance a weight, such as is shown at fi and 5', may be added, removed, or transferred, as the experiments proceed. The scale-pans and weights should depend from knife-edges at a and h, in tlie usual way where delicate weighing is required. The method of the experiments is as follows in a case where a full set of four weights is employed : — May 1, 1888.] ♦ KNOWLEDGE ♦ 153 All the four weights to be used in a given set of experi- ments are to be first cai-efully weighed against each other, in pairs, above A B and below D E. every pau- being thus tested, each weight in each test being put on one side of M in one trial and on the other side in another, and the indica- tions of the long light-pointer cai-efully noted in each of the twenty-four trials thus made. [Six pairs of weights can be selected from the four ; and taking any pair, v: and vj' , these can bo weighed against each other in two ways in the upper weight-holders, and in two ways in the lower, or four ways in all. Thus twenty-four weighings must be made to eliminate all errors arising from differences — however minute — between the weights.] Next each pair of weights must be balanced against each other, one being above and the other below. One such trial is illustrated in iig. 2. The weight w above A, which should exactly balance the weight w' set in the scale-holder above B, will not balance here:. ON THESCALEOF THIS FIGURE. A WRTICk. DISTANCE OF ABOUT 13 INCHES IfJTERVENEi Fig. 3. w' set^below E. For while each is drawn downwards with equarforce by the earth's mass — or with only such minute and calculable difterence as results from the distance of w from the earth's centre being greater than the distance of w' — to is drawn towards C, or downwards, by the attraction of the great globe A BD, while w' is drawn towards C, or upivards, by the same attraction. The amount of deflection, as indicated by the light-pointer, is to be carefully noted ; then the weight iv is to be transferred to B and the weight w' to D, when an opposite deflection will take place, which is to be similarly noted. Next the two experiments are to be repeated, the weight iv' being above and the weight w below. Corresponding experiments are to be made with each of the six pairs of weights which can be formed out of the four. The mean of the observed de- flections compared with the mean of the twenty-four pre- ceding observations (in all of which the beam is approximately horizontal) will supply the means of compax-ing the attrac- tion of the earth with the atti-action of the globe A B D. Of course many details must be taken into account : as, the weight of the wires or cords along A D and B E ; the angles such as C tn D and C iv'B when w and lu' are in equilibrium ; the difference of the distances of w and w' from the earth's centre ; and the like. But all such matters are readiU' calculable from the original data and the indica- tions of the ray- index. Here is a rough calculation of the effects we may expect to recognise in such experiments : — Supposing the globe A B D to be of lead, and therefore of twice the mean density of the earth, and i feet in diameter, its mass compared with that of the eai-th is as 2(2)^ to (10,500,000)3; but the weights w and to', neglecting theii- distance from the surface of the large globe and from the vertiaxl diameter, are only 2 feet from the centre of the globe, while they are 10,500,000 feet from the centre of the eai-th. On this account the attraction of the globe is greater than the attraction of the e00s. for single correct letters. 37,oOOs. for two „ „ 8,000s. for three „ „ 2,000s. for lour Total . lOO.oOOs. paid on prizes. The sum paid in, at 5J. for each of the 456,976 tickets, would be 190,407 shillings, and it is Ln this degree that the public, in purchasing large numbers of tickets on this plan, are wronged. That is, they pay 190,407 shillings, and get back on tlie average only 100,000 .shillings on each set of 456,976 trials. But the promoters of the scheme have to pay one halfpenny for each ticket issued, and charge a penny for postage — according, at least, to their circular ; so that they actually make 228,488 pence, or 19,041 .shillings, more, by this seemingly slight overcharge for postage. At a moderate computation of the expense for printing tickets, advertising, etc., the " National Prize Competition Society " make the usual proportion of profit on the lottery they conduct, viz., between eighty and one hundred per cent 1 It is at this rate that the Louisiana Lottery Company get the better of their foolish victims. The Geneva, Hamburg, Brandenbui-g, and other lotteries, get similar gains. The " National Prize Competition Society " advertise their lottery scheme as " a novel system of money-making " — and truly, in one sense. The deluded public suppose the money-making is for them, but the society attends to that part of the business, and, though the system is in reality old enough, yet it has been so clothed in a new garb that it tiikes in the weaker sort just as thoioughly as though it were altogether new. How it has come to pass that, as I am told, the law has not yet stopped the " novel system of money-making," and punished the law-breakers, I know no more than I know how it comes to pass that respectable serials have pei'mitted the " National Prize Competition Society" to advertise in their columns. THE RELIGION OF THE ANCIENT BRITONS.* ROFESSOK EHYS'S satirical reproach in his preface that " of course it is not pretended thaD anything connected with the history of religion among the Celts — or among the Teutons, if it comes to that — could vie in popularity with the pedigree of the last idol unearthed in the East, or even with the dis- covery of a new way of spelling Nebuchadnezzar's name," is fully warranted. For we have been indolently content to remain in shameful ignorance concerning the question of the religion of the races dominant in these islands before the lloman inva.sion. Our training, both at home and school, on Sundays as well as on week-days, has fostered this ignor- ance. Classical studies have usurped, and still unduly usurp, the scholar's time, as if all of value in the history of mankind is confined to a strip of Mediterranean seaboard. Romulus and Remus, Cecrops and Pisistratus, are f imiliar uames to the student ; perchance he has heai'd of Arthur, but not of Nud and Manannan MacLir. He knows the Iliad and the Odyssey, but not the songs of Edda and the breezy, bracing sagas, the Volsung and the Niblung, which, as William Morris says, " should be to all our race what the Tale of Troy was to the Greeks." And, in like manner, as the old artificial division of history into " profane " and " sacred " shows, instruction in the religious development of mankind rarely, except to point a false moral or a mis- leading contrast, passes beyond the age and races covered by the Bible. For the larger number of folk, the political history of Britain begins with the invasion of Julius Ca?.sar, and its religious history with the mission of Augustine. Out of the material gathered by the famous emperor, as the result of jjersonal observation, and by Tacitus, whose information was, however, secondhand, a few sentences describing the general features and mode of life of the " ancient Britons " were spun, and then the story of the successive invasions which resulted in the " making of England " was woven according to regulation pattern. Whether the wild tribes * " Lectures on the Oriyin and Growth of Religii.n, as illustrated by Celtic Heathendom." Ey John Rhys, Professor of Celtic in the University of Oxford. (Williams & Norgate: 1888.) May 1, 1888.] ♦ KNOW^LEDGE ♦ 161 of the northern and western parts, and the somewhat more advanced tribes of the southern pirts, of the island were aborigines, and if not, whence they had come, and what was their relation to the races overspreading the northern hemisphere, concerning whom no written records exist ; what remains, either tangible, as weapons of war and the chase, or intangible, as language, legend, myth, and custom were extant, neither historians nor antiquaries tarried to ask. What a vast and interesting, if obscure, field they left unexplored we are beginning to see, thanks to the industry and zeal of Professor Rhys and kindred labourers. The old indifference and ignorance, due not only to defects of educjition just referred to, but also to the delusion that " when Britain first at Heaven's command arose from out the azure main,'' she succeeded to the spiritual lordship and pi-ivileges which the Jews had forfeited,* and appeared equipped, Minerva-like, complete in all wisdom needful to eternal salvation, are giving place to the desire to know whether the couree of man's progi'ess in these islands runs parallel or not with that of other civilised races, and if so, what evidence is supplied by survivals. It is as a contribution to this question that Professor Rhys's volume, in which the history of religion is for the first time com[)reliensively treated from the Celtic point of view, demands attention. Its somewhat late place in a. valuable, if unequal, series itself illustrates our remarks on the tardy recognition of the importance of ancient British religions, but better late than never, and we will not lay reproach at the doora of the llibbert Trustees, who are spending their money to good purpose. Rarely has a more obscure and tough subject been taken in hand than this with which Professor Rhys bravely grapples, for the materials are not only scanty and scattered, but are often hard to interpret. They consist of a few references in ancient writers, and of inscriptions on votive tablets and other monuments preserved in local museums and described in transactions of provincial societies. Draw- ing primarily on Ciesar's account of the Gaulish religion, which may be taken as applicable to the religion of the British Celts, since they migrated from Gaul, Professor Rhys has sought to identify the Gaulish with the Roman Pantheon. He remarks that, " unfortunately for the study of Celtic religion and philology, few of the monuments of Gaul supply us with inscriptions in the national tongue ; and probably all of them, whether in Gaulish or in Latin, date after the advent of the Roman conqueror and the initLation of his policy of assimilating the gods of vanquished Gaul with those of Rome. This policy took a very definite form under Augustus. He, as ponti/ex maxlmus, united the religions of the Roman world ; but the manner in which Africa and the E;ist were treated could not be recommended in the case of Gaul and Spain ; so when he undertook to restore the position of the Lnres and Penates he included among them the Gaulish divinities, who were henceforth styled Augusll. The result in each instance was that the name of the Gaulish god came to be treated more or less as a mere epithet to that of the Roman divinity, with which he began to be regarded as identical : thus the (iaulish Grannos became Apollo Grannus, and Belisama became Minerva Belisama, and so in other cases. ... In a word, the Gaulish gods and goddesses were reduced in rank, and forced, so to say, to become more or less Roman ; but they * A delusion of course rampant among the eccentrics who believe in the descent of Britons from tlie lost Ten Tribes, and wlw identify the British Lion with the Lion of the Tribe of Judali !

The search for resemblances is justified not merely by the similar polytheistic stage of the conquering and the conquered races, but by their common, if remote, relationship, Celts and Romans being members of the scattered Aryan family. As illustrating the method adopted in this volume : when Ctesar speaks of the Gauls as making Mercury the inventor of arts, the patron of trades (as he was among the Romans) and of roads and journeys. Professor Rhys cites an inscrip- tion in which the god is described as Mercurio Aug. Artaio, the Gallic atlix bsing cognate to the Celtic ilr, plough-land. Again, Mars, god of war, is equated with the Gaulish god Caturix, a compound meaning king of war or lord of battle, tablets having been found near Geneva and elsewhere with this inscription, Marti Catur(igi), kc. Ca;sar tells us that Mercury was worshijjped as supreme, and the degradation of Mars, who was once the chief Celtic god, to the third place (Apollo being second) is, as Professor Rhys remarks, probably due to the progress of the people in the arts of peace. How far the author has succeeded in his laborious attempt none but Celtic scholars can determine ; and even were we competent to dt^liver judgment, our readers would resent the introduction of the abstruse and tedious matter which this would involve. They may share our reliance on the caution and accuracy which have thus far distinguished Professor Rhys's investigations, and may follow him with confidence through this labj'rinth where lurk the disguised and disfigured gods whom our predecessors worshipped, and who have in many cases still further eluded us by becoming changed into the kings and heroes of romance. Certain it is that the Celts had their departmental deities, and that the characters of these were more or less akin to nature- gods of other polytheistic races. Among these stand out the Celtic Apollo, healing sun- god, Belenus, the reputed founder of Caerleon, and from whose name some derive Billingsgate ; Aine or Aina, queen of heaven, mother of the gods ; Taranis, god of thunder, to whom certain trees and plants are sacred ; Manannan MacLir, a sun-god ; Nodens, or Nud, and his alter ego Lir, seagod, worshipped both in Britain and Ireland. During the Roman occupa- tion a temple was erected to Nodens at Lydney on the Severn, his wife being the Irish goddess of the Boyne, while Lud, whose name reappears in Shakespeare's " Lear," and whose daughter figures in Celtic romance, perhajjs survives among us in London, if that name be not, as some anti- quaries think, derived from Llyn-Diu, the " lake-forfc." Upon this Professor Rhys has the interesting remark that " the association of Llud, or ' King Lud,' as he has come to be called in English, with London, is apparently founded on a certain amount of fact : one of the Welsh names for London is Caer-Liid or Lud's Fort, and if this is open to the suspicion of having been suggested first by Geoffrey, that can hardly be supposed possible in the case of the English name of Ludgate Hill. The probability is that as a temple on a hill near the Severn associated him with that river in the west, so a still more ambitious temple on a hill connected him with the Thames in the east; and as an aggressive creed can hardly signalise its conquests more eflectually than by appropriating the f^mes of the retreating faith, no site could be guessed with more probability to have been .sacred to the Celtic Zeus than the eminence on which the dome of St. Paul's now rears its magnificent form." But besides the major gods of the Celtic Pantheon, there is a crowd of dii mitwres, both native and borrowed, spirits of forests, springs, and rivers, which last had their own special divinities, as shown in the Dee and other streams with kindred names. The mountains were dedi- cated to airy powers; every village was protected by the 162 KNOWLEDGE ♦ [May 1, 1888. "mothers," oi' guardian spirits, who ap])ear in medifeyal legends as the White Ladies, the three foiries, the weird sisters, the wild women of the woods ; while in the giants and dwarfs and the fairies and goodies of nursery legend other minor deities reappsar. Forming a dark background to this spritely company, we find another and older creed, familiar to us as Druidism, concerning which the most foolish speculations and bizarre theories have been broached. Upon this Professor Ehys has much to .say which is of interest, and in connection with which we advise the perusal of his little book on" Celtic Britain,"* as also of the chapter on the religion of the British tribes in Mr. Elton's scholarly and delightful " Origins of English History." f As this latter book is out of print, it may be we'l to quote the opening sentence from Mr. Elton's fine chapter : — The religion of the British tribes has exercised an important influence upon literature. The medi.tval romances and the legends which stood for history are full of the "fair humanities" and figures of its bright mythology. The elemental powers of earth and fire, and the spirits which haunted the wavts and streams, appear again as kings in the Irish .annals, or as saints .and hermits in Wales. The Knights of the Round Table, 8ir Kay and Tristram, and the bold Sir Bedivere, betray their divine origin by the attributes which they retained as heroes of romance. It was a goddess, Bca quirdani j)liaiiiastica, who bore the wounded Arthur to the peaceful valley. " There was little sunlight on its woods and streams, and the nights were dark and gloomy for want of the moon and stars." This is the country of Oberon and of Sir Huon de Bonrdeaux. It is the dreamy forest of Arden. In an older mythology it was the realm of a King of Shadows, the country of " Gwyn ab Nudd," who rode as Kir Guyon in the " Faerie Queene," And knighthood took of good Sir Huon's hand. When with King Oberon he came to Fairyland. The history of the Celtic religions has been obscured by many false theories which need not be discussed in detail. The tr.aces of revealed religion were discovered by the Benedictine historians in the doctrines attributed to the Druids; if the Gauls adored the oak- tree, it could only be a remembrance of the plains of Mamre ; if they slew a prisoner on a block of unhewn stone, it must have been in deference to a precept of Moses. A school pretending to a deeper philosophy invented for the Druids the mission of preserving monotheism in the West. In the teaching of another school the Druids are credited with the learning of Phrenicia and Egypt. The mysteries of the "Thrice-great Hermes" were transported to the northern oak-forests, and every difficulty was solved as it rose by a reference to Baal or Moloch. The lines and circles of st.anding stones became the signs of a worship of snakes and dragons. The mined cromlech was mistaken for ,an altar of sacrifice with the rock basin to catch the victim's blood and a holed-stone for the rope to bind liis limbs. In inquiring into the origin and nature of Druidism, it is necessary to have a clear idea of the succession of races in Britain prior to the Roman invasion. We may leave out of this list the men of Paljeolithic times who ranged the country under a more or less arctic climate, waging war against the huge mammals of tho Quaternary epoch, and whose chipped tools and weapons are found in the river- drifts and under cavern floors, for it is certain that no continuity of race can be proved between these savages and any tribe or nation now found in Norlh-Western Europe. Between their disappearance and the arrival of a more advanced race great physical changes occurred, Britain having been submerged, then laised, reunited to the Con- tinent, and then finally separated. But the I'ritain of Neolithic and far later times, down to a period long subsequent to the Roman invasion, was, in its superficial features, not the Britain of to-day, but a land of fen and forest, the highways through which determined the ancient boundaries of its several kingdoms. Despite Mr. Ruskin's * Published by S.P.C.K. London. 1882. f London: B. Quaritch. 1882. Jeremiads on tho degradation of the climate of England through the blotting out of her skies with " Manchester's devil darkness, and sulphurous chimney-pot vomit," and of the troubling, not as by the angel at Bethesda, of her streams with the pollution and filth of her factories, we are in much better case now than then. When the legions of C;esar first disembarked they found the island little better in most parts than " a cold .and watery desert. According to all the accounts of the early travellers the sky was stormy and oliscured by continual rain, the air chilly even in summer, and the sun during the finest weather had little power to disperse the steaming mists. The trees gathered and condensed the rain ; the crops grew rankly, but ripened slowly, for the ground and the atmospliere were alike over- loaded with moisture. The fallen timber obstructed the streams, tho rivers were squandered in the reedy morasses, and only the downs and hill-tops rose above the perpetual tracts of wood." The herds of mammoths, rhinocero.ses, and other pachyderms ; the cave-lions, cave-bears, hyamas, and other beasts of prey, that had roamed through the jungles and wallowed in the rivers during the alternating polar and tropical climates of the Old Stone Age, had vanished, and in their place wild boars and o.xen (the urns of Ca'sar), elks and other animals, for the most part extinct, tenanted the forests and swamps. Wolves prowled over the long desert that stretched from the Cheviots to the Peak ; beavers built in the streams ; and only the cry of the cormorant and other sea birds broke the silence that reigned over the expanse of peat-bog that .stretched inland on the west, over tho swamps of the midlands, and over the dreary fens that spread in monotonous flatness eastwards. Masses of forest so dense as to bo in some districts impenetrable, stretch^ ing, as did the Andredsweald, one hundred and twenty miles, with wide expanses of moor and swamp, that surrounding the higher ground where Ely Cathedral now stands exceed- ing sixty miles across ; narrow strips of arable, and wider breadths of pasture land, spread over the estttaries and across tho inland valleys — such, broadly outlined, were the features of England from pre-Roman times till a thousand years later, despite much that had been accomplished by the military spirit of the Romans and the industrious energy of the Saxons, whose work the Norman, with his passion for the chase, undid so ruthlessly. This description of the physical .aspect of our island applies still more to the Neolithic age, when no Aryan husbandman had yet struck his plough into the soil, or burned the timber into charcoal for the smelting of tho abundant ore. The earliest known Neolithic settlers in Britain were a short and thickset people, with long or oval heads, dark hair, probably swarthy complexions, .aquiline noses, long n.arrow foreheads, and with the tibia or shiiibone presenting in many cases that flattened, sabre-like form, called platycnemi.a — a feature not so much indicative of ape-like ancestry as of physical change dire to the freer and more constant use of certain muscles which are brought into action in hanti)ig game on foot, and such-like occupations. These people, the Kynesii, of whom Herodotus speaks as dwelling outside the Pillars of Hercules, furthe.st away towards the setting of the sun, are now generally identified with the remnants of non- Aryans known to us as Iberians, found in various parts of Europe, descendants of the wide- spread race whose relics — tombs, and stone circles marking the transition from burial-place to temple — exist by thou- sands in both hemispheres. Notable among these remn.ants are the Basques, living in the Western Pyrenees, and speak- ing a relatively modern language which is the sole survivor of the Iberian family of speech, and, fo far as is known, without affinity with .any other language in the world. But it is obvious that unless the untenable and indolent theories May 1, 1888.] ♦ KNO\VLEDGE ♦ 163 of some historians respectiDg the universal extermination of subject races in these ishinds be accepted, some traces of such a folk are not to be confined to the Basque district, and in proof of this we hare indications of their presence nearer home. There are in many parts of Ireland, of the Highlands of Scotland, and the Western Isles, traces by no means infrequent of a short, black-haired, long-headed stock, described as having a strange foreign look, of whom the late Mr. Campbell of Islay, in his remarkable collection of tales gathered orally in the West Highlands, gives a typical example. He says, " Behind the tire sat a girl with one of those strange foreign faces which are occasionally to be seen in the Western Isles — a face which reminded me of the Nineveh sculptures and of faces seen in St. Sebastian. Her hair was as black as night, and her clear dark eyes glittered through the peat smoke. Her complexion was dark, and her features so unlike those who sat about her that I asked if she were a native of the island, and learned that she was a Highland girl." * Neither is the swarthy type absent from England and Wales, not only in ancient Siluria (comprising Glamorganshire, Brecknock, Monmouth, &c.), but in some parts of East Anglia, also in the south- west, and even in the Midland Counties, in which last, with their traces of the predominant intiuence of the Saxon and Danish conquerors, we might expect to find only a fair- haired and light com plexioned folk. •■When we consider the many invasions of strangers, and the oscillations to and fro of difierent peoples, it is impossible not to realise the strange persistence of the race. Through nil the troubles which followed the conquest of Gaul by C.-esar, and of Britain by Claudius, through all the terrible events which accompanied the downfoll of the Roman Empire, causing the Britons to be exterminated over a large part of England, and the almost total extinction of the ancient type of Roman in Italy, the Iberian lived, and still is found in his ancient seats, with physique scarcely altered, and oflering a strong contrast to the fair-haired Celtic, Belgic, and German invaders. The Iberian race is known to the ethnologist and historian merely in fragments, sundered from each other by many invasions and settlements of the Aryan race. It is shown b}- the researches into caves and tombs to have been in possession of the whole of Europe north and west of the Rhine in the Neolithic age, and has been traced by Dr. Yirchow into Germany and Denmark." f Next in succession to it is the Celtic immigration, the invasion of Britain by tall, round-headed, fair-haired, large- limbed men, bringing with them a mighty motor power in human progress in their knowledge of the use of the metal bronz? which they had acquired along the route. These Celts were divided into two groups, the one, and the earliest to cro.ss the sea and repeat the conquest of Gaul in the con- quest of Britain, being the Gaidhelic or Gaelic, formerly written by themselves Goidel. From this branch, the Goidelic, are descended the people in Ireland, the Isle of Man, and the Northern Highlands, who speak Gaelic. The second group, the Brythonic, from Brython, the Welsh form of Briton, are the ancestors of the Welsh people and the Britons, the ancient Gauls being also included with them, since the Brythons were Gauls who came over to settle here. To one of these two branches every Celt belongs. The remains of these Celtic and of the pre-Celtlc peoples indicate what befell the latter. The round barrows of the wolds of Yorkshire contain about an equal proportion of the .skeletons of long-shaped and round-shaped skulls, pointing to intermai'riage and generally friendly relations between the tn'o ; but in the southern parts of the i>land the round- headed type is dominant, pointing to the expulsion of the pre- Celtic. {To he concluded.) * " Tales ot the West Highlands," iii. 14 1. t Boyd Dawkins's " Early Man in Britain,' p. .S31. Emin I'dfilia in Central Africa. Being a Collection of his Letters and Journals. Translated by Mrs. R. W. Felki.\. (Geo. Philip ct Sons.) — Pending the arrival of Stanley's relief expedition the world is longing to know all it can about the brave and unselfish Emin, and his friends have exercised a wise discretion in publishing the letters and extracts from journals which he has sent to various correspondents during the past ten years. To future generations, when time shall have given its truer propor- tion to events which are yet too near us for right focus, there will, we think, be no more striking and dramatic figures of our day than Gordon at Khartum and bis trusted friend Emin, who happily survives to maintain firm and bloodless rule in Central Africa, protecting his people from the slave-hunter, and refusing to desert them at the prospect of approaching relief. In the last letter which this book gives, dated Wadelai, April 17, 1887, he tells Dr. Felkin that he will not leave his post. " If the people in Great Britain thiok that as soon as Stanley or Thomson comes I shall return with them, they greatly err. I have passed twelve years of my life here, and would it be right of me to desert my post as soon as the opening for escape presented itself? For twelve lorg years I have striven and toiled, and sown the seeds for future harvests, laid down the foundation-stones for future buildings. Shall I now give up the work because a way may soon open to the coast ? Never . . . All we would ask England to do is to bring about a better understanding with Uganda, and to provide us with a free and safe way to the coast. This is all we want. Evacuate our territory ? Certainly not I " * And this is the man to whom our late poltroon Government permitted the Egyptian Government to "give the sack," to put it plainly, in the early part of 1886. "It is," Emin says, " a cool business despatch in the fullest sense of the term, not acknowledging by a single word the cares I have borne for three years, my fights with Dangola and negroes, my hunger and nakedness, not giving me a word of encouragement in the superhuman task of leading home the soldiers, which now lies before me. However, I am accustomed to this sort of thing. In the years 1878-80, during which the river was blocked for twenty-two months, I held the country and people together, and showed for the first time that we could maintain ourselves by our own strength without any supplies from Khartum, and not only did I spare the Government expense at this time, but also proved practically that the province could, under an honest administration, yield a surplus. . . . Yet, who has given me even a word?" Emin, "the Faithful" (faith justified by works, in this case) is the Turkish name which, to smooth his intercourse with the Mohammedans, was adopted by Eduard Schnitzer, who was born in 1840 at Oppeln in Silesia. He became a student of medicine, and his passion for travel and love of natural history carried him to Turkey, where he procured an appointment on the staff of the Yali of Asia Minor, and ultimately entered the Egyptian service, being sent to Khartum, and thence, as the chief medical officer of the Equatorial province, of which * Since this notice was written, a letter appears in the Timrs of April 10, under date Wadelai, August IC, 1887, from Emin Pashi, expressing the same firm resolve. 164 ♦ KNOWLEDGE ♦ [May 1, 1888. Gordon was governor. The two men became fast friends ; and when Gordon was appointed Governor-General of the Soudan he promoted Emin as governor of the Equatorial province, which extends from nine degrees to two degrees north of the equator. A clear and indispensable map, which Mr. Eavenstein has engraved for this volume, enables the reader to follow with ease the various journeys described. It is the record of these visits to the dilferent parts of his province that the letters and journals mainly embody, and they supply a vivid and interesting narrative of the incessant and varied work which Emin has carried on in the face of stupendous difficulty, danger, and discouragement. While engaged in raising and drilling troops, substituting native for Egyptian soldiers, promoting trade, encouraging cultiva- tion of coffee, indigo, cotton, and other products, adding large districts to his territory, not by war, but by skilful negotiation, converting a deficit of over 30,000/. into a surplus of 8,000Z., Emin has also found time to make e.^ten- sive observations on the geology and general features of the province, to form large collections of its jjlants and animals, and to gather copious details concerning the manners, customs, and beliefs of its various tribes, notably of the Monbuttus, a cannibal, but, in many respects, advanced race, to whom he devotes a special section (pp. 18(5-213). Despite a good de;vl of inevitable repetition and of sameness in details, the letters and journals deserve to be read with- out skipping, a task the more easy because their translation has been so skilfully done by the wife of Emin's missionary friend.

By Joseph Prestwich, Professor of Geology in the University of Oxford. Vol. II. (Clarendon Press.) — This volume completes the important work into which the ripe results of fifty years' study of the science at which the Oxford pro- fessor has laboured con amove are gathered, and it is from cover to cover worthy of his high reputation. We notice that the publishers give prominence in the advertisements of this book to the advocacy of " the non-uniformitarian views of geology " by its distinguished author, but surely lie can be no party to the sounding of this note of challenge, since his attitude is not that of the defiant extremist which that implien. The day is happily past when the scientist is •sunk in the partisan, for the diflerences between contending schools are often found to be rather of terms than of prin- ciples. Because Lyell, after careful sifting of evidence, abandoned the old catastrophism and argued from the ascertained opei ations of existing causes, that th e same causes, allowing for variation of degree, have sufficed to bring about past changes, a host of purblind followers have contended for an unalterable tiniformitarianism. It is against such extreme applications of the doctrine that Professor Pj'estwich contends when he says that " while the laws of chemistry and physics are unchangeable, and as permanent as the material universe itself, the exhibition of the consequences of those laws in their operation on the earth has been, as new conditions and new combinations succe.s.sively arose in the course of its long geological history, one of constant variation in degree and intensity of action." * Perhaps the word " constant " implies more than we are prepared to admit, but, as Pro- fessor Huxley remarked in his anniversary address to the Geological Society in 18C9 on Geological lleform, " there appears to be no sort of necessary theoretical antagonism between Catastrophism and Uniformitarianism. On the contrary, it is very conceivable that catastrophes may be part and parcel of uniformity." And he illustrates bis meaning by the working of a clock, the good time-keeping Vol. i. p. VI. of which means uniformity of action. " But the striking of the clock is essentially a Gitastropbe ; the hammer might be made to blow up a barrel of gunpowder or turn a deluge of water ; and, by proper arrangement, the clock, instead of marking the hours, might strike at all sorts of irregular periods, never twice alike, in the intervals, force, or number of its blows. Nevertheless, all these irregular, and appa- rently lawless, catastrophes would be the result of an abso- lutely uniformitarian action, and we might have two .schools of clock thcori.sts, one studying the hammer, and the other the pendulum." In his first volume Professor Prestwich dealt with the nature and distribution of the materials forming the crust of the earth, and with the several agencies by which, in the remodelling of those materials, the strati- fied have been developed from the unstratified rocks. The present volume treats of the original condition of that crust, of its anatomy, history, and organic contents, and concludes with a discussion of those abstract phy.sical and cosmical problems which relate to the evolution of the globe and of the system to which it belongs. The distinctive feature of the author's treatment of the stratigraphical branch of his subject is in his insistance on the impossibility of any universal scheme of classification, the formations in distant areas being correlated not by identity of species, but by the presence of the same characteristic genera, the large community of which amongst the Invertebrata everywhere is most striking. He remarks that " the great time- divisions are of almost universal application, but the smaller ' breaks in continuity,' which are of frequent occurrence in all areas, are subject to constant differences of extent and value ; consequently, in filling up the details of the several geographical areas, each one is found to have its own local stamp, and possess its own special terms, some knowledge of which is as essential to the geologist as is the language of a country to the traveller, if he would pass through it with profit " (p. 3). As novel and informing commentary on this, we have several tables of classification showing the equivalent strata in various parts of Europe, and in America, Asia, Africa, and Australasia, with brief " lists of the characteristic genera of plants and animals attached for the purpose of showiug the distribution of some of the more important life forms over the globe at the several con- temporaneous epochs." Altogether, the space given to the geology of other countries is a unique and valuable feature of the volume. Convenient summaries of the faunas and floras of each period are supplied, so that a great mass of facts is helpfully grouped for easier gi-a.sp by the student, for whom also an abundance of excellent plates and wood- cuts, together with a geological map of Europe, are provided. In the chapter on the Quaternary or Pleistocene period, to our knowledge of which the author's researches have largely added, some remarks on the place of man in the geological record are included, and it is significant of a turn in the tide to find Professor Prestwich admitting the probability of man's existence in North-Western Europe in the glacial epoch, the duration of which he thinks may not have been longer than from 15,000 to 25,000 years. This is in keeping with the generally shorter estimates of time than are usually demanded by geologists which characterise the volume, and so far jiaves the way for reconciliation betweea geologists and physicists. Chamherss Encyclopcedia. Vol. I., A to Beaufort. (W. & R. Chambers. 1888.) — The publishers remind us in their preface that their great work has been before the world in complete form for twenty years. Revision has gone on at frequent intervals, but the time has arrived for an entire recast of the matter, involving the rewriting of a large proportion, so as to bring down the information to date. So far the work has been well and thoroughly done ; May 1, 188S.] ♦ KNOWLEDGE ♦ 1G5 and never did an undertaking more nobly redeem the promise of its preface than this first volume of the new edition, which, for the convenience of the many, is also iinder issue in monthly parts. Even to the few who can afl'ord to buy the bulky " Encyclopa?dia Britannica ' this moderate sized and cheap companion is as indispensable as the " finder " to a big telescope. Not relying solely on authorities whose names might justify our taking their contributions on trust, we have gone over the majority of the articles with considerable care, and the result warrants the highest [jraise that we can give. Mr. Grant Allen's article on Anthro- pology is a masterly and lucid survey of the science ; the cognate articles on Animism, Animal- and Ancestor- Worship are models of brevity and clearness, while includ- ing material for the reader to form bis own judgment on Herbert Spencer's and o[)posing theories : the article Ballad, by the same skilful hand, has had the advantage of revision by Andrew Lang and others. Professor Tail's article on the Atom supplies, inter alia, an untechnical account of the periodic law of the elements ; the article on Matthew Arnold — now, -we must sorrowfidh' add, gone to his rest — seizes in a few words the characteristics of his work both in prose and verse ; while among the contributions from the United States, the insertion of which happily protects the work from Transatlantic thieves, we must single out as especially complete and interesting Dr. Greene's article on the American Indians. Per contra, under Animal, the writer, in speaking of the presence of chlorophyll in certain infusorians and other inver- tebrates, overlooks Sach's explanation that it is not a proper constituent of their bodies, but due to the presence of vegetable cells which they assimilate; under archa;ology. Dr. Anderson has not sufficiently insisted on the totally unlike conditions and characters of the Palaeolithic and succeeding ages ; the discovery of a deep .sea A,scidian {Octanemus Btjthii's) by the C/ialknger ex- pedition might have been noted in the article under that heading, and the article on the Aryans will soon need con- siderable revision. To descend to trifling errors, " Robert Maitland " should be " Thomas Maitland " in the article on Anonymous. We should add that the maps, which are both political and physiail, and also the woodcuts, are very superior to those given in the old editions, and that the typography is perfect. Marahuna : a Romance. By H. B. Marriott Watson. (Longmans.) — We think this story marks the approaching exhaustion of the modern romantic school, to which Hugh Conway's and Eider Haggard's tales gave chief impetus. It was an inevitable reaction from the colourless, anah'tical, white-of-egg flavoured studies of Howell and James, making any change of diet welcome to the confirmed novel-reader. Not that this book lacks an original side, but that the combinations are limited and the surprises discounted. The talk on shipboard is too " high-falutin'," and Marahuna herself inspires languid interest, the only quality in her n hich gives force to the character is akin to that which Grant Allen presents so powerfully in " For Maimie's Sake." The scenes of the story alternate between the Antarctic circle and Hampshire ; the origin and flite of Mai-ahuna our readers mu t learn from the book itself. Civilisation and Progress. By John" Beattie Crozier. New edition. (London: Longmans it Co. 188S.) — No one can rise from the perusal of the work whose title heads this notice without the conviction that its author has es- tablished a claim to stand high among the most profound and original thinkers of the day. He has set himself an ambitious task, and he has very narrowly indeed escaped entire success. In his search for a consistent theory of civilisation and progress, Mr. Crozier successively discards the histoiical, the metaphysical, and the psychological methods, and founds his own new organon on " the laws of the human mind in its entirety as a concrete unity " — an e'astic definition which crops up, as a deus ex machind, throughout the work. That such laws are immutable is taken for granted. Portions of the work before us must irresistibly attract the reader. We may instance chapter vii. of Part. I. and the whole of Part IV. among them. But the man who sets himself to frame a new method for the investigation of the factore and causes operative in the advancement of the human race should above all things be impartial, and this our author assuredly is not. His unreasoning admiration of democracy in the abstract to a large extent blinds him entirely to its operation in the con- crete. Certainly his picture of America is evolved from the depths of his own moral consciousness. Everyone personally familiar with the United St;ites knows that jiolitics there are practically abandoned to the scum and dregs of the population, and that an American gentleman (and there is an upper class even in Mr. Crozier's model Piepublic) repudiates with scorn and loathing the slightest sympathy or fellowship with the caucus -mongei-s, log-roller.^, and wire-pullers who dominate all political matters what- soever there. A great many hard things have been written and said about the Corporation of the City of London, but Mr. Bottomley Firth himself would scarcely dare to in- sinuate the pos-ibility that the Lord Mnyor and Aldermen could ever be guilty of the infamous corruption and pecula- tion of which the municipal authorities of New York were convicted at a compai'atively recent date. As for current French Republicanism, no further reference is needed to it here. When evolution shall have develo])ed a superior type of the human race, Mr. Crozier's supposititious Re- public may become an accomplished fact : at present " the laws of the human mind," as known to us in their out- ward manifestations, present an insuperable bar to the realisation of his Ltopian dream. The constitution of a country may confer political equality upon every one of its citizens: but to suppose that they can or ever will become socially equal is as reasonable as to imagine that their height or the colour of their eyes can be regulated by a statute. Jla'gre the small display of fanaticism which has elicited these remarks, the author of " Civilisation and Pro- gress " has produced a work of very high merit, and one which will repay perusal and reperusal. The English in the West Indies ; or, the Bow of Ulysses. By J. A. Froude. (Longmans.) — In the present work Mr. Froude gives us the result of his acquaintance with a very different batch of colonies from those which formed the subject of his brilliant sketches in " Oce;ina." If it lacks the freshness and vigour of that book, drawn as these quilities were from the material dealt with, it has a more romantic flavour, mixed with bitterness at the neglect which has allowed whilom bright jewels in the possession of the Crown to become dull and tarnished, or, as the author in repeated metaphor says, the bow of Ulysses to remain unstrung. In his own matchless prose Mr. Froude tells how tha Caribbean Sea, from Trinidad to Jamaica, was the cradle of our naval empire, the scene of exploits to furnish the most stirring cantos if ever England's victories on the seas are done into an epic poem. All the romance of adventure and conquest in the New World defiles before us ; every hero, from Columbus to Drake and Rodney, is there, " the captains of the ships and all the ships in order." But the main subject of the book is the West Indies of to-day, with the problems of England's position towards the decreasing white and the increasing black populations, which our party leaders, miscalled statesmen, ignoring inherent difi'erences in the capacity and power of self- 166 ♦ KNO^A^:.EDGE ♦ [May 1, 1888. control of races of mantiiul, liave aggriivated by their exportation of parodies of the mother institutions — house- hold suffrage, representative assemblies, and so forth. They have ignored the fact that the personal relations between master and servant liave ceased to exist with the abolition of slavery, and that the political elevation of the negro has done, and can do, nothing to establish new relations. We must confess that Mr. Froude, although paradoxical as ever, makes out a strong case for the government of those islands as Crown colonies. No tinkering with their political con- stitution can arrest the decay of their staple industry — .sugar ; capital and enterprise can only be tempted to remain in Jamaica, Dominica, and other suffering islands, or be attracted thither anew and be engaged in remunerative channels, by the firm rule of white over black. Let the superior race withdraw, and the negro populations will relapse into barbarism, with its revolting superstitions, cannibalism, devil-worship, &c., as they have in llayti. We have said enough to indicate that, as a contribution to the mode in which tlie mother-country is to discharge her duty to these neglected, but lovely and fertile, islands of the West Indies, Mr. Fronde's book demands serious perusal. Juvenal in Piccadillij. By Oxoniensis. (Vizctelly ct Co.) — Satires seem almost anachronisms nowadays. Since Alfred Austin published his " Season " we do not remember one that has .appeared to lash the humours and follies of the towzi until the present brochure, which, free from the exaggerated tones of the great Roman, finds material for its crisp and brightly-written verse in vices and affectations which have changed their zone but not their nature. Messrs. Blackwood & Sons send us a new and almost entirely rewritten edition of the late Professor David Page's Introductorn Text-Booh of Geology, the merits of which need " no bush " from us ; from Messrs. Smith & Elder we have Volume XIV. of their noble Bidionai-i/ of National Biotjrapln/, comprising Damon to D'Eyncourt, and therefore including the famous name of Darwin, the article on whom is fitly ii-om the pen of his son and biographer; amongst current serials we have to acknowledge the West- minster lieview, containing a delightfully fresh paper on Heine; the Cenliiri/, the C'l/dopaalia of Education, Lowj- maris, in which appears Mr. Be.'ant's important pai)er on making provision for girls ; and Bahij, an Illustrated ^[afjazine for Mothers, which, we ho|)e, will be received by them as its prospectus says it has been received by the press — "with open arms." The author of ,S'iuilig/it (reviewed on p. 140) complains that we I'epresent him as explaining gravitation by the action of light, whereas he only stated that light "developed" gravitation. He further objects to a quotation from his volume anent meteorites being earthy atoms separated from the air by cold pressure and vegetation. What he meant was that by "the death and decouipo.sition of Fauna and Flora their dusts do rise, and may become constituents of meteorites when separated from the air by cold pressure " (!). We trust that our readers will appreciate the value of these corrections, and judge how far they aftect the validity of our original judgment on the book in connection wdth which we have been asked to make them.

Blackburne was made the victim of the severe criticisms and strictures of one of those professors of " the art of problem construction," who make problems, solve problems, and judge problems according to strict rules and canons. Herr Spitzleris not satis- fied with a mere effort of the imagination con- ceiving a pretty idea and shaping it into problem form ; he has ajsthetic notions about " beauty of construction," " economj- of force," "difficulty," "originality," " purity," "harmony," &c , and unless a composition can stand all these tests, the Professor does not think much of it, Accordinglj', when Jlr.

Not so, however, the Professor, for, said he, " Speaking .of end-games generally as played by great players, I do not think there Is any cause for great admiration. In most instances a mate is accomplished by brute force, and though a piece or two may be sacrificed, yet the object is the same — to force mate in a few moves by a most direct method, check, check, check, and mate Com- pared with a fine problem," be said, " the best end-game played is but a clumsy and raw production. I have never yet seen a mate forced in an end-game by a quiet and non-threatening move, which makes problems so beautiful." " Well," said a well-known chess editor, " I think I can show that Professor Spitzler is wrong in his basis of comparison between end- games and problems, and his consequent strictures. For the sake of comparison, let me ask you whom would you think the greater general, the commander who wins an actual batlle in the field bj' rough lliough clever and bold manoeuvres ; or the staff officer who, in imitation of this event, works out a scheme which he puts into execution on the parade ground, when, as a result of a sham fight, both armies being like clay in his hands, he wins a battle with greater ' brilliance,' ' economy of force,' ' difficulty,' ' harmony,' and * purity of manteuvring ' .' ' And as for the assertion that the quiet move is never found in practical end-play, I can contradict that by a game just received by the American mail, which was played only last month by Steinitz at Havanna.

I'OTS on the sun are both small and very infrequent' liut his disc may be watched on clear days. The in,;,'ht sliy is depicted on map v. of " The Stars in tlieir ISeasons." Mercury is a morning star at the licginning of May, coming into superior conjunc- tion with the sun on the 10th. Then of course he travels to the east of the sun and becomes an cNening star. At the end of the month he may be caught with the naked eye after sunset, over the N.W. by \V. part of the horizon. Venus is a morning star, but her appearance is singularly insignilicant when compared with that which she presented last November, when so many fatuous people hailed her as " the star of Rethlehem." Mars is still a striking object in the n'ght sky, but his angular diameter is steadily and sensibly decreasing. It will be noted, too, by the sharpsighted observer with the telescope that he is no longer quite round. He will be found between 8 and y Virgiois (-'The Stars in their Seasons," map v.). On the night of the 5tU he and Uranus will be so close together as to be in the same low-power tield of a telescope. Jupiter is visible near to midnight, in fact sooner, but is so very low down that to be seen in the least degree favourably he should be looked j. AVhen the stone is brought to rest this kinetic energy remains in the movements of the stone's particles and of the particles of air around it — either in actual displacements, or in the vibratory motions whose efl'ects are rendered sensible as heat. The former neither falls under definition a nor under definition h, because the particles moved draw towards some and from other particles. Nor can the vibrating particles be said to display attractive or repulsive (aggi-egating or separating) tendencies, their motions being essentially alternating. Mr. Clodd's — or rather, I suppose, Mr. Allen's — barrel of gun- powder has, on the other hand, unquestionably separating or expansive or repulsive potencies, which become kinetic when the powder is fired. Yet even here definition h does not apply to these tendencies in the rigid or definitive manner imagined by Mr. Allen and conceded by Mr. Clodd. The bottom of the barrel is pressed towards the ground bj- the action of what is technically called the explosive force of the powder ; a fragment of the barrel, after flying a certain dis- tance, strikes some other body : in each case the action dis- played— so for as the wood, the ground, and the struck body are concerned — is of the kind producing motions drawing particles of ponderable matter together, not separating them. If this reasoning is objected to for the reason tluit the particles of gunpowder alone are to be understood as having potential energy according to definition h, the fault lies with the definition, which either says too much or too little — too much if we are to be thus limited, too little when the case of the stone is considered (for where are the particles potentially tending to separate in the stone's case ?) The fact is, Mr. Allen has obviously misunderstood alto- gether the trouble in regard to the inexact expressions em- ployed occasionally by Sir R. Grove and Professor Tyndall (one may add Professor Huxley and Mr. Herbert Spencer), a mistake arising rather from the assurance that they could not be misunderstood, than from want of familiarity with the accepted limitations of the words " force " and " energy " as technically used from the time of Newton tintil now — in treatises on dynamics. Sir W. R. Grove was taken to task, in somewhat pedantic sort, for speaking of electricity, heat, light, and the like, as physical " forces " in the title of his well-known work and elsewhere, instead of always (as in many parts of that treatise) speaking of them as " afl'ections of matter." He in eflTect replied that the word " forces " as thus used could not well be misunderstood. His chief object had been to show that those " aflfections of matter " are " modes of motion," and every one would know that " modes of motion " cannot be described as " forces." Considering specifically (p. 18) the objection that "the term force" should be used " not as expressing the eflTect " (that is, motion or some afiection of matter involving or depending on motion) " but as that which produces the eflfect," he says, " this is true, 172 KNOWLEDGE ♦ [June 1, 1888. and in this its ordinary sense I shall use it in these pages " — because " the terra has thus a potential meaning, to depart from which toould render lamjtuige uniiUeUi/jible " ; though, as he quite correctly points out (the remark in no sense i.ffeoting his opinion as to the impropriety of any attempt to alter the technical use of the word "force"), " we must iruard against supposing that we know essentiall}' more of the phenomena by saying they are produced by something " ( force), " which something is only a word derived from the constancy and similarity of the phenomena" {motions of various kinds) we seek to explain by it. Assuredly Sir \V. R. Grove would be far from welcoming the proposed limitation of the word " foi-ce " to one-half of its accepted significance, and the substitution of the word " energy " for the other half, with accompanying maltreat- ment of " attraction " and " repulsion " scarce!}' less pain- fully tending to (and suggestive of) bewilderment. Professor Tyndall was very sharply, and as I think most unfairly, taken to task for using the word " force " (both in the singular and plural) as Sir W. E. Grove had done. Yet Professor Tait was undoubtedly right in saying that " the sense in which Newton uses the word ' force ' is the sense in which we should continually use it" (if we are professedly using it technically) " if we desire to avoid intellectual confusion." And certainly Tyndall, who re- peatedly distinguishes between attractive and repulsive '• forces," and clearly recognises the correct meaning of "energy" as simply the capacity (potential or active) for doing work, would ha sorely troubled at the thought that any looseness of expression on his part, where his real meaning could not be misunderstood, should have suggested the astounding idea of merging the distinctive word " attraction " into the general word " force," and the equally distinctive word " repulsion " into the word " energy," which (as constantly used in scientific treatises on dynamical physics) is perfectly distinct from all three. Professor Huxley, whom I hold to be the most perfect living model of the man of science (because of all men known to me he is the readiest alike to maintain what he considers should be maintained and to concede what he considers should be conceded), used the word "forces" where, as he afterwards noted, the more general term " powers " would have been better. Is he likely, therefore, to rejoice to see the good old word which has now for two centui'ies done the .same office in ten thousand scientific treatises invited to do half duty, and another word of entirely distinct character invited to abandon its own useful office and do the other half of that duty] Far from it. AVith characteristic manliness he goes out of his way (as weaker men v.'ould hold, but such a man as he can spare the extra travel when it seems necessary) to say that he would rather now write " powers " where he formerly wrote " forces." How Mr. Clodd has come to regard this frank admission by Professor Huxley that the word " force " should be limited to its proper use, into support of the entire misuse of that word (and others) I altogether fail to understand. What men like Sir Wm. Thomson (whom Sir R. Grove — rather significantly — calls Thompson), Pro- fessors Cayly, Adams, Sylvester, and their like, would say to the suggestion that the words "Force," "Attraction," "Repulsion," and "Energy" should be shuffled about as Mr. Allen has suggested I can guess, though I would rather not say. Tlie mildest punishment they would intlict — though I fancy it would not be found very easy penance — would be that Mr. Allen sliould suggest some way of expressing the ideas now represented by " Energy," " potential energy," and " kinetic energy " ; for assuredly his new definitions, whether regarded as rigid and definitive or as loose and ill-fitting, would leave these conceptions entirely unrepresented. The more severe would suggest that Mr. Allen should revise according to his novel ideas the whole body of scientific literature relating to matters dynamical. The nature of the task may be inferred from the first two steps which would have to be taken. How- would Mr. Allen re-word the two first laws of ISTewton, remembering that, though originally written in Latin, these laws were repeatedly referred to by Newton as worded in English, thus? — - I. Everij body ■pe.rseveres in its state of rest or of uniform motion in a riyht line, unless it is comjMlled to change that stale hy forces impressed on it. II. The alteration of ^notion is even proportional to the motive FORCE impressed, and is made in the direction of the right line in which that force is impressed. ilay I be permitted to present a parable for the benefit of — whomsoever it maj' concern 1 For centuries the words " trade " and " wealth " (" poten- tial "and "material") had been used in all treatises on Political Economy in the sense in which tliey are still understood. But it chanced that several writers — among them an able theologian, a learned lawyer, and an ex- perienced archaeologist — in writing on their several subjects used the word " trade " where the more general word " com- merce " would have been better, and seemed (but only seemed) to confound the word " mani;factures " with the expression "material wealth." A pedant or two corrected this, though the writers criticised pointed out that no one could misunderstand their meaning. Hearing of this, an entomologist of great acumen as a naturalist and singularly graceful as a scientific writer, but whose studies gave him no actual occasion to write about trade or commerce or manufactures, or political economy generally — who, in fact, rather disliked these subjects — advocated an entire change in business language. Let us hereafter, said he, call all forms of importation trade and all forms of exportation vjealth. ... It was urged that the four good words — — Trade, Import, Export, and Wealth — would all be put to entirely new uses, if the change were adopted ; that the literature of political economy would have to be rewritten ; and that new expressions would now have to be adopted to express what had heretofore been understood by Wealth, Material Wealth, and so forth. One might as well, said one, speaking as in a parable, propose that Dress should signify the Clothing of Men, and Costume the Clothing of Women. Whether the innovator (who had in the mean- time taken to writing fairy tales) was convinced, this de- ponent sayeth not. But the new usage was not adopted^ and it never will be. Mr. Grant Allen would do well to test the idea expressed in his privately published pamphlet by preparing a small treatise on some dynamical subject involving all four of those conceptions — " Force," " Energy," " Attraction," and " Repulsion " — respecting which he has been moved to anxiety. Unless I mistake, he would find his rigid and definite meanings perplexingly elastic and confusing. A pamphlet on the motion of a shell moved by the repvdsive action of exploding powder, and travelling in a resisting medium, first against the attractive action of gravity, and afterwards in response to that action, would afl^ord excellent exercise, not only for the writer, but for the reader (if the new nomenclatui'e were consistently adopted), especially if the shell were suffered to explode just before reaching the earth, and the movements of its parts (assumed equal and of given number) were carefully dealt with. Science is entitled to ask that those who suggest new uses for words which have been for centuries used {by Her, at any rate) in determinate ways, should in some such way show the con- venience and value of the new nomenclature, and manifest June 1, 1888.] ♦ KNOW^LKDGE ♦ 173 some sort of right (based on special knowledge) to propose changes in the language of science. My protest has been urged in the interests of the class of writers for whom I my.-elf have striven to cater, and for whom Mr. Grant Allen and Mr. Clodd have catered most successfully. The former in particular (I know my friend Mr. Clodd will not be angry with me for putting the matter thus) is, to my mind, simply unequalled by all our English writers on popular science for grace and elegance of style and versatility of treatment. (It grieves one to the heart to think that powers such as his should for want of the due appreciation of science in our day be increasingly wasted on those who appreciate only sensational fiction.) But it is because I feel deeply interested in the spread of Found information about scientific matters among the general public, that I protest earnestly against changes which, by separating the language of scientific literature from the language of exact science, would tend if accepted to make " confusion ■worse confounded " — bj' replacing mere ditficulty of appre- hension (such as all exact scientific studies involve) by sheer bewilderment. Carelessness in the use of scientific terms is doubtless unfortunate ; but studied inaccuracy would be a disastrous remedv. THE STAR STORY OF THE FLOOD. [Continued from j/aye 147.) jMONG the constellations which have thus been deprived of their ancient character, none equalled in interest the great ship Argo. It is difficult for any one who studies a modern map of this constellation to imagine that it was ever like a ship. Nay, the resemblance cannot now be well traced even in the heavens, for a reason presently to be con-idered. Yet the configuration of an immense ship, with lofty, well- rounded poop, with masts and sails, and deck and keel, is singularly striking, when the original extent of the con- stellation (reduced by modern astronomers) and its original position (changed by that slow precessional reeling of the earth which has for its period 29,000 years) are taken into account. As to the original extent of the gi-eat ship Argo, astro- nomers of two distinct ages have been at work cutting ofl^ parts of the ship piecemeal. Originally, as the heavens still tell us, the ship had a noble prow as well as that lofty stern of which I have spoken. But the astronomers of some 2,500 years ago, in altering the figure of a man standing at the prow into a Centaur, removed to make the horse part of the Centaur the stars which had originally formed the prow of the great ship. (I have no authority for this last state- ment except the prow-like form which the stars of the Centaur's body picture ; but for the former there is the evidence of ancient astronomers that the constellation which later represented the centaur Cheiron — identified by some with Noah — originally represented a man, not a man-horse.) In the time of Eudoxus (about four centuries before Christ), ■whose ideas about the constellations the poet Aratus pre- sented two centuries later, Argo represented the stern half of a ship, drawn backwards into harbour. I find that, as might be expected, thus corresponds with the aspect and position which the constellation then had. "When at its full height in the southern skies of Greece, or Egypt, or Persia, Argo's keel was aslant, the stem end being consider- ably higher than the fore part, so that as the diurnal motion carried Argo along stern first, the motion was like that of a ship drawn stern first up a slant shore. At present this idea is no longer suggested, the slant being now so great that nothing but hauling a ship stern first up a cliflf would correspond with the celestial position and motion of Argo ; and ships are not so commonly hauled up cliffs in that manner, that even the most imaginative mind would find such an idea absolutely forced upon it. In the time of Eudoxus also, the poop of the ship had been to some degree interfered with as -nell as the prow, for some of the stars of the stern are wanted to complete the figure of the Greater Dog. But probably in Eudoxus's time there was not the least difficulty in regarding these stars as doing double duty. The fore-half of the ship had been bodily removed, but the outline of the stern was not pro- babh- impaired at all to make room for Canis Major. In our time, of course, this has happened. The outline remains still somewliat like that of an ancient poop, but it is not nearly such a fine poop as the old ship had. Not only the stare marking the dog's hind quarters have been removed, but as the outline of the poop is thus contracted, another group of stars formerly belonging to Argo can no longer be included within the outline. Out of the stars of this group Hevelius formed the constellation Noah's Dove, apparently judging that it was a rather ingenious device to represent the dove as flying from what was originally the rudder (or stern oar) of the ark. But the moderns have done worse even than this, clipping off one part of the keel of the ark to make, or help in making, a Chameleon, and another part to help in making a Flying Fish. This was Lacaille's work. On the other side — that is, in the ship's upper works — he was equally absurd, setting in the ship's masts — or perhaps on the roof of the ark — an Air Pump, of all unlikely objects to occupy such a position. Another modern constellation, the Southern Cross, though really part of the original ship, was taken from it long before modern times, to form the hind feet of the Centaur. The modern astronomer, there- fore, has not constructed the Cross out of the ark, in which there might have been found a world of suggestive meaning, but has abstracted it from what was already an abstraction, the hinder portion of the centaur Cheiron. So soon as we picture the stars of this region as they were in the time of the Great Pyramid, and (practically) for three or four centuries before and afterwards, we find such a ship as the modern stellar skies no longer present— a constellation so striking that even the least observant must have recognised its ship-like form. In the first place, Argo fills in the most remarkable part of the whole heavens. Covering the richest region of the stellar skies, it is bordered by a broad tract which is abso- lutely the darkest part of the star-sphere. Between the thinly strewn region -nhich marks the sails and mast of the ship as at present pictured, and the long winding stream of stars marking the sea-serpent Hydra, over a tract ex- tending from the head and shoulders of the Centaur to the constertation of the Little Dog — a range of nearly ninety degrees ! — there is not a single star of the first, second, or third magnitude, whUe there are only three stars of the fourth, and very few of the fifth magnitude. The rich tract formerly occupied by the Great Ark, and now occupied by the Centaur, Cross, Southern Fly, Argo, the Dove, and the CJreater Dog, though less in extent than this poverty- stricken region, contains six first-magnitude stars, twelve of the second magnitude, thirty-two of the third — that is, no fewer than fifty stars of the first three magnitudes alone, besides an amazing waalth of stars of the fourth, fifth, and sixth magnitudes, and widely spreading masses of the Milky Wav. Ihe region thus richly crowded with stars of all orders, and distinguished from the sun-ounding heavens not only by the poverty of the region just described but also by another but narrower poverty-stricken region on the other 174 ♦ KNOWLEDGE ♦ [June 1, 1888. side (the keel line of the ship), is about eighty degrees long and forty degrees broad. Now, in the time of the Pyramid builders, this region was so situated that its length was parallel to the horizon when the region was at its highest above the southern horizon. Thus the great ship had its proper position as floating on a sort of heavenly sea, the horizon of which was the celestial equator, along which was the great Sea-serpent, floating lazily ouwards — for the motion of the star sphere carried Hydra forwards, his head reared above the sea level, towards the west. It is to be noticed also that the elevation of the ship above the natural horizon of Babylon, Persia, Greece, or Egypt, was such as to give the ship the most natural appear- ance possible, for the keel would be actually on the horizon of the three first-named regions, and raised very little above the horizon in the latitude of Athens. From a picture which I have drawn showing the southern skies of Babylon at midnight in winter — about the time con-esponding to the middle of December — I find that Argo must then have pre-sented such an appearance that it would require no liveliness of imagination whatever to picture a grand celestial ship there — nay, rather that only the dullest imagination could fail to have this idea suggested to it most strongly. Certainly the scene then presented by the star- strewn skies .above the southern horizon was more striking than any which the skies present now, in any latitude and at any hour. Recognising this remarkably suggestive aspect of the heavens in the days of the pyramid builders, and remem- bering the importance attached to the ship Argo alike by ancient observers of the stars, and as belonging to ancient myths, I was led to inquire further respecting the constella- tions brought successively above the southern horizon as the year passed on. In the first place, I observe that preceding the arrival of the great Ship .as the ruling southern constellation at night, there came a long array of those watery constellations — Capricornus, Aquarius, Pisces, and Eridanus — which the ancient astronomers regarded as undoubtedly associated with Hood and deluge on the earth. Till far later times, the belief prevailed that when all the planets are conjoined in Capricorn the world would be destroyed by flood ; but the superstition had its origin in that remote time to which we are now extending our survey. An old idea of mine was thus recalled to me, that in the constellations of the watery kind (as the old astrological astronomers considered them), the ship Argo, and certain others, the story of the flood as related in Genesis is presented — men either finding in the lieavens the record of what had happened on the earth, or picturing a series of events in the heavens which they later transformed into a terrestrial legend. But now I had the means of dealing with this idea much more satisfactorily than when I touched upon it formerly in a merely sug- gestive way. For, in the first place, I now had the' exact aspact of the stellar heavens for every month and every hour of the night at the time to which the story must be referred, and in the latitudes whence the Egyptian and Babylonian astronomers observed the heavens ; and in the second place, the reading of the Ninevitish cuneiform inscriptions on the one hand and the study of Egyptian Biblical lore on the other, had thrown enough light on the deluge narrative to show how it was in a general sense to be interpreted. In what follows, I employ the story of Noah in Genesis chiefly as giving the best record we probably have of what at the time of the Captivity was the accepted account of the deluge as to times and seasons. Probably the cuneiform inscriptions, as read by Messrs. George Smith, Sayce, and others, present rather a popular form of the legend than the full record which the priests of Babylon possessed, and which they were ready to communicate to the more learned and devout among the Hebrew priests. At any rate, it is clear that precise details as to dates were given to the scribes and priests of Judah, and by them transferred to their sacred books, the narrative being only so far modified as to emphasise the story of the origin of the Hebrew race as the chosen people of God. The story, alike in Egypt, in Babylon, and in Jerusalem, relates to the tenth of the first generations dealt with by legend or history. Noah is the tenth antediluvian patriarch ; Hor is the tenth Egyptian god ; Xisuthrus is the tenth Chaldean king. The idea associated with the deity, king, or patriarch — according to the race among whom the story appears — is that of rest. The singular prophecy by Lamech respecting Noah, thus finds a partial interpretation : " This same shall comfort us for our work and for the toil of our hands because of the ground which the Lord hath cursed." But the explanation becomes clearer when we recognise in Noah a solar hero, and in the account of the deluge a very ancient solar myth — as Gold- ziher, Steinthal, and other Hebrew scholars (rejecting Pro- fessor Max Miiller's idea that the Hebrews had no mythology) have learned to recognise. Xisuthrus is the sun at setting ; the journey of Xisuthrus is the journey of the sun at night below the horizon : but also, as in all solar myths, the sun is dealt with here as god of the year, not solely or even chiefly as god of the day. Thus, the hero of the deluge legend is the god of winter, which, like night, brings rest from agricultural labours. As in all solar m3'ths, however, we find in the legend of the deluge the record of a full year, and — as has long been considered remarkable by Bible commentators — precisely one year of 365 days. The life of Enoch, it is to be noticed, is given as 3G5 j-ears, and it is noteworthy that a certain confusion may be recognised between Enoch and Noah, as between their Egyptian and Babylonian analogues. The seventh Egyptian god, like the tenth, is named Hor ; and, again, Xisuthrus, the Babylonian Noah, is translated after the close of his achievements as a solar hero, as Enoch is translated after his solar life of 30.5 days. It is true that the year of 365 days was not in general use either in Egypt or ChaldsEa ; but the length of the year was known to tho astronomers of the Pyramid time with much greater accuracy than even the period of 365 days would indicate — probably it was known within a few minutes of the true value. Just here it may be noticed that the Jewish Midrash compares the course of the sun to a ship coming from Akramania (wherever that may be) with 365 ropes, and to a ship coming from Alexandria which has 354 ropes (354 being the number of days in a lunar year). There is a Phrygian legend that the king or patriarch Annakos, i.e. Enoch, being more than 300 years old, pre- dicted the flood, and prayed with many tears and lamenta- tions for the people. The dates directly associated with the flood in the Babylonian account, presented (we may assume) in Genesis, belong to Mesopotamia, where great floods attain their greatest height in spring, at the season indicated as the time when Noah's flood w-as at its highest. Dr. Bell tells of a flood in Mesopotamia so high at this season, that as far as the eye could reach nothing could be seen from the highest tower of the Baghdad mosques but a great waste of wateis, studded here and there with a few date groves, which appeared like little islands : '■ Thousands of square miles," he says, " were at that time under water." These floods commonly begin towards the end of October, and the waters continue to increase, though the rains are not continuous until sju-ing. But, of course, the Baby- lonian record of the flood, though it may have been June 1, 1888.] ♦ KNO^ATLEDGE ♦ 175 suggested by a natural Mesopotamian flood of this kind, relates to a Hood much more widespread and far more terrible ia its eSbcts. We have here intermixed, after the customary mythical fashion, the magnified and intensided events of an ordinary flood, the diurnal progress of the sun- god (and especially his joui-ney in a ship beueatli the horizon) and the annual journey of the sun as god of the year, during a time when all the heavenly powers combined their influence in the watery constellations. So much premised, let ns trace the annual progress of the constellations which, at the time of the Pyramid builders and their Baliylonian fellow-workers in astronomy were below the horizon of the star sphere — marked by the equator — and let us see how far the constellations as pictured corrft'^ponded with the . events recorded in the narrative. It is to be observed that the mere agreement of a few cases would count for little. The agreement of several, in precise order, as well as in the characteristics of the con- stellations, would be more significant. But if we shall find the whole circuit of the star-sjihere corresponding with the Babylonian narrative as presented in Genesis, and even the dates and periods there mentioned adequately represented, then, as it seems to me (regarding the matter as merely one of probabilities), the evidence will be decisive. I picture to myself observers stationed in the grand meridional gallery of the Pyramid of Cheops, or in some similar observing passige in the Temple of the Planets at Babylon, watching, night after night, throughout the year, the constellations occupying the southern skies below the celestial ecjuator — which at the Egyptian observatory ranged sixty degrees above the southern horizon and .some two degrees less above the Babylonian. Only it must be remembered that the constellations they would see on the midnight sky would be those whose influences would affect their solar god, not at the season of observation, but iust half a year before or after, when the sun would be travelling through or past those constellations. Beginning, then, with the seventeenth day of the second month, which all agi-ee would correspond with the end of October, we find the part of the stellar heavens in conjunc- tion with the sun to be the beginning of the watery constel- lation C'apricornus, regarded by ancient astronomers as of all the signs the one which most directly threatened flood. Thence for the space of nearly five months' journey the sun was in conjunction with none but watery constellations. After the Seagoat came the Water-Bearer Aquarius, whose jar and the streams flowing from it are pictured very strik- ingly in the heavens, however imperfectly shown in the modern much-i-educed constellation. Then follow Pisces, the Sea-Monster Cetus, and the streams of Eridanus. (In my opinion the water streams from the vessel borne aloft by Aquarius were regarded as extending over C'apricornus on the one side, and on the other over the Fishes, the Sea Monster, and the great river Eridanus, the whole of this large region of the heavens being most curiously traversed by a network of interlacing star-streams.) For one hundred and fifty days the sun was in conjunction with these watery signs, viz , from the end of October till about the time of the spring equinox, when also the terrestrial skies in Babylon seemed to respond to the.se watery influences. Now it is noteworthy that, although this watery region extended over one hundred and fifty days' sun-journey, the special flood signs extended only over forty days of the solar path. From the beginning of Capricornus to the place where the main stream from the water-can of Aquarius crosses the sun's path — or from near Alpha of the Seagoat to near Phi of the Water-Carrier, there are just forty days of solar travel. This corresponds precisely with the record of the flood. The rain was on the earth forty days and forty nights — and after the end of an hundred and fifty days (including the forty) the waters decreased. At this stage we find, in the stellar story of the flood, the Ark floating on the wide expanse of pictured sea. Above, along the equator, lies (or rather lay, at the time to which we are looking back) the fall length of the great Sea-Serpent ; below that water horizon extended a broad tract of star- less sky ; and below that again the starry splendour of the great ship her.self. Counting now to the tenth month on the first day of the month, ■' when the tops of the mountains beg.an to be seen, we reach the place where Cor Hydr», the Sea-serpent's Heart, stood on the equator, the horizon of the celestLal sea. Then followed forty days more, at the end of which Noah opened the window of the ark which he had made, and sent forth a raven." Now just at the corresponding pomt we find the ancient constellation of the Rxven, standing on the Sea- serpent, or just above the equator, as if finding no place on the land. If we were to trust the modern pictures of the Haven, this might seem of little moment. For with charac- teristic perver.sity, the modern map-makers have turned this constellation upside down, and the case becomes one of those referred to l)y Mr. Lang, when the liveliest imagina- tion can trace no resemblance between a star gi-oup and the object pictured. But the old globes and charts set this light. The raven is in reality a very characteristic bird. His high-shouldered attitude when at rest, and a certain angularity of wing then shown, are features which strike the observer at once. Now the constellation Corvus, repre- senting the chief of the Corvidce, the Raven, is also striking. It is a small group, but well marked, and surrounded by conxparatively vacant skies. So soon as we picture a Eaven standing upright on the Sea-serpent's back, not as in modern pictures in the attitude of a fowl picking up seed, we recog- nise the outline of a raven in the star-group, as distinctly as we see a Dolphin in the group so called, a crown in Corona Borealis, and other objects in similar small but well-defined groups. Thus the Haven of the flood story is well pictured in the heavens, and occupies precisely the position corre- sponding to the dates in the Babylonian record, as preserved for us in (ienesis. Then follow three weeks, or twenty-one days, correspond- ing to the intervals at which the dove was sent forth. I might dwell on this reference to the week, the first of the kind in the Bible pages, as of itself sufficing to indicate the astronomical, and especially Babylonian origin of the story. But I pass on to consider the I'est of the record. I cannot find three doves in the stellar picture, nor could they be reasonably looked for. It is curious, however, that there are three characteristic undulations of the tail of Hydra, i.f. stars which recpiire to bo connected by an undulating line to keep up the serpentine idea — ranging over precisely three weeks of the diurnal motion of the star-sphere. The crests of the undulations are marked (1) by the stars Gamma and Psi; {i) by the star Pi; and (.3) by a set of five small stars bearing no Greek letter, but numbered by Flamsteed 5-i to 59. And now we have reached the prow end of the ark, and find standing there the human part of the Centaur, a fine manlike figure. This constellation has always been regarded as bearing sacrifice to the Altar, Ara. He was upright in the southern skies at the time we are dealing with, a circum- stance which helps the imagination in picturing the figure of a man. His head was marked by a group of small stars ; Theta and Iota marked his shoulders, Alpha and Beta his feet. A long straight row of stars, extending on the east to Kappa, marked the spear or rod, on which ho bore an animal, later called a wolf, towards the altar. Few of the human constellations are so characteristically defined in the 176 * KNOWLEDGE ♦ [June 1, 1888. heavens as the man part of the Centaur, with his spear and offering for sacrifice. Standing upright, some twenty-five decrees in height, and so that as seen from the ascending passage of the Great Pyramid, he just stood, when due touth, within the portion of the heavens commanded by the srrand eallery, this stellar figure must have presented stroncrly the idea of a man offering sacrifice — at least to a race accustomed to see their priests daily engaged in sacri- ficial observances. But the Altai-, where is that t The constellation of the Altar is there still, both in the heavens and in our maps. But since the fifteenth century the altar has always been represented upside down, insomuch that the Centaur is represented as carefully applying a wolf to the altar's in- verted base, a proceeding which would have seemed un- reasonable even to one of the drunken Lapithre. However, there is luckily no sort of doubt that this arrangement of the altar is only a " modern improvement." The Farnese globe shows the Altar upright — that is, as upright as it could be since the precession of the equinoxes tipped it over. Manilius distinctly suggests its uprightness when he speaks of the Altar as Ara, ferens thuris, stellis imitantibus, iijnem. For an inverted Altar could not have been seen as bearing any- thing. Turning to the heavens of 3400 or 3500 B.C., we find the Altar truly upright, and we see the smoke of the incense, imitated by stars in the rich streams of the IMilky Way, which extend from the altar like ascending clouds and wreaths of smoke, over the Scorpion on one side and over Sagittarius on the other. The brightest galactic stream here is that over Sagittarius, where, indeed, the 'Milky Way has at once its most resplendent and its most variegated aspect. The incense smoke from the altar on the side towards Scorpio fades off into the dark background of the sky, but on the side towards Sagittarius there is a bright and continuous stream, gathering in places into I'ich cluster- ing masses. The sacrifice of Noah is accepted by Deity, the smoke bearing the essence of the fire-consumed flesh was of a sweet savour in His nostrils, to use the quaint expression of later Bible writers. " And God said," says the ancient record we are following, " This is the token of the covenant which I make between Me and you and every living creature that is ■with you for perpetual generations : I do set my bow in the cloud, and it shall be for a token of a covenant between Me and the earth." It may be regarded as a mere coincidence, though strange as coming after the coincidences already noted, but certain it is that in the cloud rising from the Altar, the bow of Sagittarius was recognised by the ancient worshippers of the sun and moon and stars. There is the figure of a man or god, standing on the other side of the Altar, facing the man who offers sacrifice (coining upright, like him, on the meridian of the time we are considering), and this figure holds out in the cloud from the Altar a celes- tial bow (twenty degrees in length), which might well have been regarded by the astronomical priests of those days as typifying the rainbow, and its promise as recorded in the ancient story of the flood. And here in the stellar skies, as in the detailed record, the year has completed its full circle. Imme- diately beyond the figure of the being holding the bow, we come upon the constellation of the Sea-goat, where the story of the flood begins again in the heavens. On the seventeenth day of the second month the flood began, according to the record in Genesis, on the seven and twentieth day of the second month was the earth diy — a year of twelve lunar months had passed, 354 days (the 354 ropes of the old sun-ship story), and in addition eleven days, completing the solar year of 365 days. If we have I not here a solar myth, pictured in the stellar heavens, and, as it were, reflected in the terrestrial skies, and the annual floods of Mesopotamia, then it would seem as though all belief in solar myths and nature myths must be rejected ; for certainly in not one single case have the believers in such myths found such evidence as we have found here. I do not say that no such evidence might be collected for those other myths. 1 believe that by the help of astro- nomical research the evidence of those myths can be greatly strengthened. But certainly in the present case, the first I think which has ever been dealt with in this manner, the evidence seems very striking. If it is all to be exi)lained away as due to mere chance coincidence, then must the coincidence be regarded as so remarkable, that even as such it is well worth studying. GROWTH OF THE ALPS.* HE Alps have been studied longer and more thoroughly than any others of the great mountain ranges of the earth. Their struc- ture is, in fact, typical. Although it is now considered doubtful whether any of the exposed portions of the Alps can be regarded as of Archaean age, there is absulutel}' decisive evidence of the growth of the Alps from Silurian strata through all the higher primary formations, and thence upwards and onwards through the secondary and tertiary periods to the great glacial age which was, as it were, the threshold of the period through which Europe is now passing. The record we have to read is necessarily imperfect. The forces by which stratified rocks are sub- jected to plications and fractures have acted with amazing energy on the Alpine strata. The characteristic features of the lower strata have gradually disappeared among those of the crystalline masses forced through them. " The whole geological aspect of these mountains," says Professor A. Geikie, " is suggestive of former intense commotion." The record has also been in large part destroyed by denuda- tion. '• Twisted and crumpled," Professor Geikie proceeds, " the solid sheets of limestone may be seen as it were to writhe from the base to the summit of a mountain ; yet they present everywhere their truncated ends to the air, and from these ends it is easy to see that a vast amount of material has been worn away. Apart altogether from what may have been the shape of the ground immediately after the upheaval of the chain, there is evidence on every side of gigantic denudation. The sub-aerial forces that have been at work upon the Alpine surface ever since it first appeared have dug out valleys, sometimes acting in original depres- sions, sometimes eroding hollows down the slopes. More- over, they have planed down the flexures, excavated lake basins, scarped the mountain sides into clifi" and cirque, notched and furrowed the ridges, splintered the crests into chasm and aiguille, until no part of the original surface now remains in sight." But though the Alps thus " remain a monument of stupendous earth-throes, followed by prolonged and gigantic denudation," they yet attest with sufiicient clearness the processes by which the material of their structure was originally formed. The volumes in which the record was written are all more or less incomplete, but none are abso- lutely missing — unless it be the first, if we can speak of the first volume of a series which in point of fact can scarcely be said to have had a beginning. * Chiefly from an article on "The Everlasting Hills," in the Fortnight!!/ Itevierc. June 1, 1888.] ♦ KNO^A/^LEDGE ♦ IT", The first leaves of the first extant volume are so blurred that their meaning is doubtful. Formerly it was held that a continuous belt of absolutely Archaean rocks can be recog- nised westwards of the central portion of the Alpine range. But now it is doubted whether the Alpine formations once regarded as Archasan aie really so. Yet even holding them, as the only possible alternative compels us, to be but metamorphosed equivalents of what originally were lower Palfeozoic strata, their record i^: scarcely less im- pressive. A little higher — that is, a little later in the volume — we find unmistakable Sihu-ian, Devonian, Carboniferous, and Permian rocks, uimiistakable becau.se of the fossil forms present in tliem. The oldest fossils actually recognised are Upper Silurian, and speak of a time which, even at the most moderate computation, must be set twenty millions of years back. No geologist, no palceontologist, no biologist of repute would admit any approach to so recent a date as that ; but asti'onomical and physical considerations appear to suggest that we should to that degree shorten the immense periods of time which the geologist regards as demonstrated by the terrestrial record. Taking only that degree of remoteness, and noting that these Upper Silurian strata rest on unfossiliferous ci-ystalline rocks which are certainly much older, our record goes far enough back to overwhelm us by the unimaginable time intervals of which it bears testimony. It is curious to read, in these older books of the earth bible, not only of organic remains speaking of the former existence of seas covering the innermost core of the Alpine range, but of abundant corals of Devonian age. For corals are the products of such slow proces.ses of formation that they are eloquent in the evidence they give respecting time. In the carboniferous strata, which belong to a later portion of this earliest Alpine record, we find evidence of an abun- dant flora, no less than sixty forms of vegetation character- istic of that era having been recognised. How many thousands of years the sea stood there and coral reefs were builded up, how long the interval may have been during which for a while these seas retreated and forests grew on the low-lying lands above their level, we cannot tell. But we know that those periods must have been incom- parably longer than those by which we measure the history of man. Red .sandstone tracts attest the progress of the Permian era and renewed presence of the sea. Higher (measuring stratigraphically), and therefore later, we find limestone strata crowded with evidence of marine life. Wiiole layers of these Triassic i-ocks are formed of the crinoid stems of fos.sil echinoderms, sea-urchins, brachiopods (including the famili.ar* but most ancient mollusc, the common terebratula), are found in large numbers. Coi-alsnre abundant, and fossil cephalopods, including multitudes of nautili, tell us not only of the forms of life present in that ancient Triassic sea, but also that the more ancient seas could never have departed wholly from the Alpine region, seeing that many of these Triassic fossils are survivals of forms of life belonging to the Palaeozoic period. In passing it may be remarked that certain strata, somewhat metamorphosed but manifestly belonging to the Trias, were penetrated in piercing the Mont Cenis tunnel, and showed a thickness of more than thirteen thousand feet. On the Northern Apennines these strata include the celebrated statuary marbles of ( 'arrara. * Familiar in appearance, and so commonly found by the sea- shore, attached to submarine bodies, that probably every one who has ever walked beside the sea has handled dozens of their shells; yet science not only recognises their vast antiquity, but has given them verj' hard names, calling them " pala;obranchiate acephalous bivalve brachiopod molluscs." The great thickness of the Triassic limestone in the Eastern Alps a[ipears to show that they must have formed in open seas, free from inroads of sandy or muddy sediment. It is believed by some that in the conglomeratic dolomites of the Eastern Alps we can recognise signs of the breakers of that ancient sea, grinding down the coral reefs and carry- ing the thin dolomites into the lagoons within. Higher and later yet, in the Jurassic sei ies, we find similar evidence. Reddish well-bedded limestones, so crowded with Terebratula diphi/a as to be called the Diphya limestone, lighter lime.stones full of ceplialopnds, immense coral reefs — all these atte.st the long-Listing intliience of this second stage of the great ^Icsozoic or secondary period in the formation of the Alpine range. Then came the last stage of the secondary period, the Cretaceous. It is strange to picture a time when, where now the Alps rear their snow-covered pe;iks, there were wide seas, beneath whose surface such layers were forming .as those out of which the chalk cliffs of Albion have been carved. Nay, we have evidence that in that selfsame region were once seas bounded by just such clifls, for while we find layers of Cretaceous formation hundreds of feet thick in the Alps, we find also intercalations of coal-bejiring fresh- water beds, showing how the seas from time to time retreated for periods long enough to permit of the aggre- gation of these coal-bearing strata. From some of the lake- beds of that age in the Alps large numbers of reptilian remains have been obtained, incliuling dinosaurs, turtles, a crocodile, a lizird, and a pterodactyle ; in all, no fewer than fourteen genera and eighteen species. Hut, of course, the greater portion of the matter belonging to the Cretaceous era in the Alps is of marine formation. And now the record brings us to recent times — not more, perhaps, than a million of years ago, or some such trifling period as that. Of the earlier tertiary era, the Eocene, the dawn of modern life-forms has left clear evidence in the Alpine rock- masses. A remarkable feature of the Eocene strata in the Alpine region is the presence of immense erratic boulders of far greater antiquity, apparently carried off by great glaciers from Archaean masses such as still exist in' Southern Bohemia, and borne across sea on ice-floes to tlie Alpine shores. But if a wide sea existed during the Eocene age in the Alpine region, there were alternations during which land appeared, for in the Northern TjtoI a seam of coal thirty-two feet thick occurs as an Eocene deposit. The Oligocene .age, still nearer to our own time, is repre- sented with wonderful fulness in the Swiss Alps. Massive mountains, such as the Rigi and Rossberg, are almo.st wholly formed from Oligocene strata, several thousand feet in thick- ness, out of which they have beeti carved. Tliey attest very clearly the presence of the sea, but they have also preserved in singular perfection large ntunbers of the plants originally clothing the neighbouring Alpine shores, and even the insects which, in those far-off ages, flitted through the Alpine woodlands. In the Miocene or latest portion of the tertiary age we have clearer and fuller evidence yet. " In the Oeningen beds," says Archibald Geikie, " so gently have the leaves, flowers, and fruits fallen, and so well have they been pre- served, that we may actually trace the alternation of the seasons by the succession of the diflerent conditions of the plants. Selecting 482 of those plants which admit of com- parison, Heer remarks that 131 might be referred to a tem- perate, 266 to a fub-tropical, and 85 to a tropical zone." Between 800 and 900 species of insects have been obtained from Oeningen. Wood-beetles were especially numerous and large. " Nor did the larger animals escape preserva- tion," to quote Geikie's rather odd expressiou, in the silt of 178 ♦ KNOW^LEDGE [June 1, 1888. tlie Oeningen Lake. Tapirs, mastodons, rhinoceros, musk deer, apes, opossums, three-toed horses, were among the in- habitants of that Alpine region. Ancient ruminants long since extinct were numerous. The huge dinotherium floated on the lake, or held on to the banks by the huge tusks of his under-jaw. Frogs, toads, lizards, snakes, squirrels, hares, beavers, were abundant, as well as numbers of small carni- vores to feed upon them ; for if Nature " never makes mouths but she finds food," she assuredly attends to the converse arrangement with at least equal anxiety. The last stage of all — that is, the last of all the grander stages of geologic time — belongs to the glacial era. As far as Lyons along the Rhone valley, extending through the transverse valleys of the Jura as far as Ornans (near Besancjon), along the Rhine valley above Basle, over the Black Forest, and down the valley of the Danube beyond Sigmaringen eastwards (joining the glaciers from the Bavarian Alps) as far as Munich, far out into the plains of Lombardy on the south, the moraines of the mighty Alpine glaciers of the Pleistocene age can be recognised. In some places the moraine rests on marine Pliocene beds ; and there are reasons for believing that In several directions the glaciers reached the sea, as those of Greenland do now. The Great Ice Age, whose stupendous records thus remain, was not continuous. In interglacial periods the ice retreated, and allowed an abundant vegetation to flourish, even in the heart of Switzerland. The strata belonging to these milder periods overlie the moraines of more ancient glaciers, inter- stratified with sands and river gravels, and are in turn sur- mounted by erratic boulders, the product of a later glacial era. With these Pleistocene pages, bringing the history down to within perhaps a hundred thousand years of our own time, our study of the Alpine record may well cease. It is but one set of books, one set out of many of like nature, some promising to be more striking still in their teaching when they have been fully studied. Other mountain ranges speak of still more stupendous processes of formation, and even of vaster time-intervals. Others, less massive, speak nevertheless of a more venerable age, since they have now gone far upon their road to decay. Others, although they have become mere wrecks, are yet more interesting as being the earth's most venerable antiques. The hills are indeed " everlasting," viewed as men must view them. Even as the stellai' regions are for us practically infinite, so do the records of the earth run over periods which are for us practically eternal. Yet in another and a grander sense the everlasting hills are evanescent. They flow From form to form, and nothing stands ; Like mists they melt, the solid lands — Like clouds they slia|ie themselves and go. Geological AHCaiTBCTURB. — A curious effect of the wear and tear to which the earth's crust is ever being subjected is exhibited in the singularly capped pinnacles e.tisting on the South River in the Wahsatch Mountains. There are hundreds of these slender pillars, ranging in height from forty to 400 feet, most of them crowned by large caps of stone. Tliey are not works of human art, as might almost be imagined, but are the memorial monuments of the once rounded hills, from which they have been cut by the action of air and water. These pinnacles alone remain of some square miles of solid rock, which has been washed away to a depth of too feet. The greater hardness of the surface has caused it to resist corrosion more than the underlying rock, thus leaving the huge stone caps perched high in air on the points of the thin columns. At one point, while this carving process has been going on, a thin wall of rock was penetrated, leaving a lofty natural bridge or arch, which adds to the picturesqueness of a remarkable landscape. DEPENDING SIMPLE MECHANICAL TRICKS ON GRAVITY. MONG mechanical tricks few are effective than those depending on more ravily, and few are more readily managed, the constructions required for such tricks being usually very simi)le. They are also highly instructive and suggestive. It is indeed easy for the young mechanician, as soon as he has caught the principle on which they depend, to devise new tricks, not less striking than those more familiarly known. In the first place it should be noted that in most of the mechanical tricks depending on gravity the observer is to some degree deluded ; for the selfsame principle of gravity may be illustrated in such a way that the experiment seems natural and ordinary, or in another which makes it appear surprising and even startling. Take, for instance, the experiment of suspending a weight on a coin standing on edge upon the point of a needle. This is illustrated sufliciently in fig. 1. Two knives K and K' are thrust into a cork C, into the under side of which, as shown in the figure, a coin, ss' (a shilling is the most convenient) is thrust. When this combination is placed in the manner Fig. 1. Fig. 2. shown, so that the under edge of the coin rests on the point of a needle n, fixed vertically in any way (as by thrusting it through a cork in the mouth of bottle B B'), the apparently unstable poising is found to be in reality perfectly stable. The knives can be struck so as either to .set the balanced combination oscillating or to set it rotating upon the needle's point, without any risk of the balance being destroyed. Though this experiment or trick has a surprising ap- pearance, the principle on which it depends may be illus- trated in practically the same way without causing any surprise whatever ; and though this is not the thing specially aimed at in mechanical tricks, yet it is instructive to see how a trick which seems surprising when perfoi'med in a particular way resolves itself into a quite ordinary experiment when difi'erently arranged. This may be done ibr the trick we have considered by means of such an arrangement as is shown in fig. 2. Here a needle or other .sharp-pointed support is fixed vei'tically into a bar A B, and on the point of this a wire beaiing two weights W and W', and attached in the manner shown to a disc D (which may be a shilling if preferred), is set simjjly hanging upon the needle's point. In this experi- ment it is so obvious that the case is merely one of suspen- sion, the equilibrium being akin to the swinging of the pendulum, that the experiment has scarcely even any interest for the observer : he sees at once that the wired weights ouf/hl to hang freely and .safely on the needle's point. But it is obvious that if we remove the part of the wire under the weights, and replace the parts D W and D W by straight wires we have reproduced — without alter- June 1, 1888.] ♦ KNOWLEDGE ♦ 179 ing the character of the experiment — the selfsame conditions which produce a more surprising result in the case illus- trated in fig. 1. There is a familiar toy which represents a di-agoon mounted on a galloping horse. This hoi-seman may be set prancing on the edge of a table in the liveliest fashion with- out any risk of an upset, and when so moving seems to pre- sent a perplexing puzzle, even though the source of his stability is displayed without anj concealment. The horse and his rider are really kept in stable equilibrium by means of a weight at the end of a curved wii'e which passes from the stomach of the horse downward and backward, so that when the horse is set upon his hinil legs at the edge of any support the weight is under the hoise's hind feet. In this position the weight is practically as the bob of a pendulum ; the only diflerence is that the weight is connected by a curved wire and the wooden figure of a horse with the part resting upon the place of suspension, whereas the bob of a pendulum is usually at the end of a straight wire. When we set the horse galloping, we set the weight underneath swinging, preci-sely as we might set a pendulum swinging ; and there is no more chance of the horse upsetting than there is of a well-swung pendulum jumping off from its place of support. A number of experiments akin to the galloping dragoon may be devised for exhibition without any special appai-atus. Take for instance a heavy handled carving fork, a cork, a strong needle, a flat-headed nail, and a piece of wood, ' and the tension along the string .« .«' make the connection between the weight suspended and the point of suspension suflicient as against all the forces which are in operation. The weight of the pencil and poker together acts vertically downward through the centre of gravity G, and since this is below the point P the equi- librium is stable. G oscillates under P, precisely as the bob of a pendulum swung from P would oscillate. In these experiments we have simply a suspended body, so shaped that when it is poised the centre of gravity is hanging below the point of suspension. Thus every move- ment given to the balanced body raises the centre of gravity above its lowest portion, just as any movement given to the bob of a pendulum raises it in greater or less degree. The swinging motion illustrates the tendency of the centre of gravity to seek the lowest position which it can attain. This is the secret of all experiments in equilibrium. In cases of stable equilibrium the centre of gi'avity tends to rise under the action of external forces, and the force of gravity brings it back, the body oscillating like a pendulum around the position of rest ; in cases of unstable equilibrium it will be found that the action of external forces tends to depress the centre of gi'a\'ity, to which movement gravity lends its aid, in such sort that the body moves farther and farther away from the position in which it had been unstably poised. The trick in the experiments above described con- sists in so arranging matters that a position of stable equilibrium is made to look like a position of instability. (^To be continued.) The well-known firm of W. Watson Sc Sods, of 313 High Holbom, occupied a very important position at the late Crystal Palace Photographic Exhibition, and their exhibits attracted con- siderable attention from the trade and amateurs alike.

The work of com- parison between the many hunJreds of drawinjrs of the planet available for stuily lias taken a longer time than anticipated. But the map will be ready now very soon. In the meantime I woidd call the atten- tion of observers to the excellent opportunity they now have for studying the featm-e which Schiaparelli attributes to " double canals." I have accepted as the best available explanation of the observed a]jpearances, that the rivers on Mars observed under different conditions account for all observed appear- ances. First. If, as is probably the case in the winter of either hemisphere of Mais, there is much cloud over a ^Martian continent, the rivers on that continent would not be dis- cernible at all. Secondly. If, as is probably the case, for some time before each equinox the clouds clear away from a continent on Mars but .still hang over the Martian rivers on that con- tinent, they would cause the rivers to appear like silver threads of exceeding fineness if Mars could be seen as he is. But in a telescope even of great aperture the points of light along the river would be seen as diffraction discs, each sur- rounded by a ring of definite diameter ; and the combina- tion of all the.se diffraction discs would form what would look like a relatively bright streak bordered by two dark streaks (corresponding to the daik spaces around each diffraction disc). [The relatively bright streaks correspond- ing to the bright rings would not be recognised as bright streaks, being merged in the light backgi'ound of the Martian continent.] Thirdly. When the clouds were cleared away from a Martian continent, and also from the rivers upon it, which must often be the case during ISIartian summer, the rivers would appear like dark streaks — of course much broader than the livei-s reall}' are, because the image of a point along one of these rivers is not point-like, even with the most perfect telescope. All that has hitherto been observed by Schiaparelli, Perrotin, Thollou, and others corresponds with the theory here advanced. (It was first advanced by me in the Newcastle Weekly C/ironicle very soon after Schiaparelli announced his startling discovery of the Martian double canals.) What is now wanted is a series of observations of Mars near the autumn of the northern hemisphere (on which most of the " double canals " have been seen). Mars will pass the equinox (autumnal for his northern hemisphere) on or about August 6, and will be well placed for this particular research during June and July. It will hardly be necessary to remind observers that they should carefully try the effect of varying the aperture of the telescope they may use. If the " double canals " are phenomena of diffraction they would be best seen with a certain aperture, such as would give to the dark ring round the diffraction di^c of a star a diameter equal to from a tenth to a twentieth of the diameter of Mars. If the space between the " double canals " be found to correspond with the span thus resulting for a given aperture, the diffraction interpretation of these phenomena would be confirmed ; if the space varied with varying aperture, and in accordance with the known relations between the aperture of the object- glass and the size of the diffraction disc, that interpretation would be established. THE NEW ASTRONOMY.* ItOFESSOR L ANGLE Y (we hope we are right about the title, but our author's title- page mentit)us nothing which in England wovdd be regarded as implying professorship) gives as the rai'ioii d'etre for his book the desire to reach those members of the com- munity on whose support the endowment of research chiefly depends. He has written, he says, not for the professional reader (whatever that may mean — in England professions are very various), "but with the hope of reaching a part of that educated public on whose suppoit he " (])resumably the " professional I'eader ") " is so often dependent for the means of extending the boundaries of knowledge." This vague purpose may be a sufficient reason for the shortcomings of the book before us. Professor Langley evidently has a very poor idea of " that part of the educated public on whose support, etc." But whether this be so or not, the mere idea of the endowment of research has long since been made to " stink in the nostrils " of the British public. Professor Langley himself has passed from a fairly salaried position with splendid opportunities (of which he has well availed himself) for independent research to a position much better salaried, but without those oppor- tunities. We propose, then, to examine his book with strict reference to its worth, and without considering (what in a different connection we would consider with enthusiasm) his undoubted services as Director of the Alleghany Obser- vatory to the caiise of <.)riginal research. In the first place, we note that " the educateil public on whose support " he depends would seem to be regarded by him as better able to judge appearances than so mere a trifle as intrinsic value. Or it may, perchance, be his pub- lishers, Messrs. Ticknor ife Co., of Boston, who suppose that the public will be content with the weight of paper and binding supplied them, without considering the amount of information conveyed, or of new thoughts suggested. Be this as it may, Professor Langley's book is amazingly heavy for the number of pages it contains, and better suited for the desk than the hand — save of the athlete to whom the raising of 5G lbs. at arm's length is a pleasing exercise. The cover positively creaks as it is opened, so stoutly and strongly (and, alas! so heavily) is it built. Sterne objected to the application of rule and square by the critic to the books he may have to consider ; but in the case of the book before us, such points as weight and structure force them- selves upon the I'eader's — or rather the holder's — attention. We find that '' Professor " Langley's " New Astronomy " weighs rather more than Sir John Herschel's "Outlines of Astronomy " and Mr. G'lodd's " Story of Creation " together. This is a serious matter. Without rushing at once to the conclusion that we can in such cases adopt the idea conveyed in the famous epitaph — Lie heavy on him, Earth : for he Laid many a heavy load on thee, or insisting with the Greek philosopher of old that a big book is a big evil, we may at least ask whether the import- ance of the contents, in this case, corresponds with the weight of the book. It may be temper resulting from wrist-weariness, or it may not, but we are moved to say that the number of pages in Professor Langley's book is surprisingly small compared with the weight ; the quan- titj' of matter surprisingly small compared with the number of pages ; the amount of astronomical information amazingh' small compared with the quantity of matter ; the proportion " The New Astronomy. Tlclcnor & Co.) By Professor S. P. Langley. (Boston : 182 ♦ KNOWLEDGE ♦ [June 1, 1888. of original matter singularly small compared with the number of statements ; and, lastly, the ratio of tlie true to the new even more startlingly insignificant. The most striking statements in the work are that the sun is much hotter than any except Ericsson, Secchi, and ZiUlner have imagined, and the moon under her midday sun much colder, for neither of which statements is a particle of evidence vouchsafed (probably because " that part of the educated public on whose support, itc," is not supposed to be capable of understanding anything so highflown as evidence). We Aentui-e to maintain the superior probability of the accepted doctrine on both points, though as Professor Langley pro- fessedly eschews mathematics and expresses even contempt for them, we cannot explain our reasons for preferring the law of Dulong and Petit to that of Newton (where the excess of temperature of the radiating body is considerable). By the general piiblic in America, the style of writing ado]ited by Professor Langley is, we understand, considered pleasing and attractive. We take a passage at random to illustrate American tastes (if we are rightly informed) in such matters. INIr. Langley is talking about the November falling star.s : — " If the reader will admit so rough a simile, we may com- pare a flight of these bodies to a thin swarm of swift-flying birds — thin, but yet immensely long " (strange birds !), " so as to be, in spite of the rapid motion, several years in pass- ing a given point " (still, we must repeat, these are strange birds l), "and whose line of flight is cut .across on the 1.3th of November, when the earth passes through it " (that is, through the line of flight of a flight of these bodies). " We are only there " (where?) "on that day, and can only see it" (what?) "then, but the swarm is years in all getting by " (sic), " and so we may pass into successive portions of it on the anniversary of the same day for years to come. The stars appear to shoot from Leo only because that con- stellation is in the line of their flight when we look up to it" (but whether "it" is the constellation, or the line, or the flight. Professor Langley does not say), "just as an interminable train of parallel flying birds would appear to come from some definite point on the horizon." (t'an we confidently conclude that an interminable train of parallel birds, whatever parallel birds may be, would necessarib/ appear to do anything in pai'ticular, unless something more definite about their interminable trainery is indicated for our guidance ?) One of the strangest things in this treatise on " The New Astx'onomy " is, that whereas the subject would seem too large even for a work as capacious as Herschel's " Outlines of Astronomy," in this work, which contains less than a fourth as much letterpress as that noble treatise (though it is priced at half as much again), the author seems constantly concerned lest each single thing he has to tell " that educated part of the pviblic on whose support, &c.," should not occupy an adequate amount of space (not to mention his anxiety to introduce matter wholly in-elevant). Here, for instance, is the way in which he spins out the stale old story of Galileo's anagram about Saturn (we can afibrd no larger type) : — " When Galileo first tumedibls glass on Saturn, he saw, as he thought, that it con- sisted of three spheres close together, the midiUe one being the largest. He was rot quite sure of the fact, and was in a dilemma between his desire to wait longer for further observation, and his fear that some other observer might announce the discovery if he hesitated. To combine th&se incompatibilities " {^ic), " to amiouDce it so as to secure the priority, and yet not announce it till he was ready, might seem to present as gi-eat a difficulty as the discovery itself " {we are not joking : every word of this is in the text ! ) ; " but Galileo solved thi", as we may remember, by writing it in the sentence, ' Altissimum planetam, tergeminum observavi ' (' I have observed the highest planet to be triple'), and throwing it, in the printer's phrase, ' into pi,' or jumbling the letters which made the sentence into the monstrous word — 8>L\JSMRMJLMEB0ETALEVMJPVNKSVGTTAVJRAS, pnd publishing ItiL^, which contained his discovery, but under lock and key.* He bad reason to congratulate himself on his prndence, iSic, Sic." * Mr. Proctor in " Saturn and His System " had a whole volume as large as " The New Astronomy ") to give to Saturn, yet we find Even this, however, is far from being the worst example of attenuative expansion in this ingeniously constructed work. As to space-filling, we have full-page pictures of a cracked glass globe, a shrivelled hand, a falling man, a lightning flash, a scene from the Bes.semer works. Pro- fessor Langley's camp at Alount Whitney, Vesuvius during eruption, and other non-astronomical matters. Thiity-one full-page pictures in the book are printed as plates (most of them being quite unworthj' of any such distinction), yet counted in the paging. But for this ingenious device (which we have never seen in any book of the sort printed out of America), Professor Langley's book, which seems to contain 2.50 pages, would show but 188. Professor Ijangley is an excellent observer in certain departments of physics (despite his weakness — and worse — in matters mathematical), and has done work which has been highly and justly valued; but he has not treated his public with resiiect, or the publishers of the " Century Magazine " (for whom the essays gathered into this volume were written) with fairness. There are five or six good (but by no means new) pictures in his " New Astronomj'," and about two pages of matter at once sound and originally suggestive ; all the rest might have been presented in aliout fifty pages, including cuts. 'The " New Astronomy " is strongly though not hand- somely bound, and well printed on singularly stout and glossy paper — but, on the whole, we feel sorry for " that educated part of the public " (presumably the American public is meant) " on whose support, &c. &c.," if the opinion which Professor Langley and his Boston publishers appear to have formed of their capacity is just. We believe, how- ever, that the general public in America, as well as in England, want the cream of science, and will not be content with a sky-blue dilution ; and we are sure that no devices of printing and binding will make Brother Jonathan regard a little treatise as a large one, though it be " fixed " as a large volume. SHAKESPEARE AND DONNELLY. AI'OLLO AND THE MUD-DAUBER. R. DONNELLY has enabled even the dullest to see what sort of value is to be attached to his critical comments on Shakespeare's work and personality. For at length he has jjublished some of the products of his crypto- gamic cyphering — products with which neither Shakespeare nor Bacon, but Ignatius Donnelly alone, has had anything to do. With regard to the legitimate criticism in Mr. Donnelly's book, we note only that it contains no new idea from begin- ning to end. The argument based on parallel passages is too puerile for comment, though we can believe that any one knowing little of Elizjibethan literature may honestly believe that the resemlilances are striking. The now notorious cypher, like all such inventions, is one by which anything whatever could be pro\ed. With four root numliers any one of which may be taken, as many modifiers, the power of counting words on any column of any page, from the top or from the bottom, with or without bracketed words, with that all the story told by Mr. Langley from "He was not quite sure" to " under lock and key " (134 words, counting the anagram a.s 4) is conveyed in 53 words as follows : — " He announced the supposed discovery to the world of science in the form of an anagram produced by transposing the letters of the sentence : • Altissimum,' &c., 'I have observed that the most distant planet is triform,' adopting this fanciful plan to prevent other astronomers from claiming the honour of the discovery." Juke 1, 1888.] ♦ KNOW^LEDGE ♦ 183 hyphened words counted separately or as one, and other variations which !Mr. Donnelly allows himself, he can, of course, find everything he wants to find. We must take what he finds as what he tells us that he wanted tlay of that name, which curiously illustrates the u.se of this term. " He came down to the footlights," said the enthusiastic narrator, describing the death scene — " he came down to the footlights — yes, sir ! — and he wrapped the star-spangled banner around him, and died like the son of a hoss." Higher praise could no American give. Hound. Although the word "hound" is in use in America as in England for a term of reproach, as also is " dog," you may use the word without offence in American society : but to use the female name for the species, even in talking about dogs and sport, is regarded by persons of the kind described under " hose " as an offence of the first magnitude. Hounds. A name very appropriately given to a gang of cowardly ruffians, akin to " white caps," " vigilants," and other such villains, who banded themselves together under the pretence of " regulating " immigration into C.alifornia in the old days of 18-1:9. It may be hoped that most of them were in the long run shot or hanged, as they deserved. How? Pronounced Jiaoivl This interjection used for ivhat 1 and intended as an abridgment of" how's that t " (for " what did you say ? "), is very often heard in New England, and not unfrequently (owing to intermixture) in other States. It has a vulgar sound, more marked, I imagine, in the ears of cultured Americans, who have learned to asso- ciate it with inferior culture, than with us English folk, who simply regard it as an amusing Americanism. How d'ye i Pronounced " howdy " — Southern for " how do you do 1 " How's THAT FOR HIGH 1 Bartlett absurdly puts as the equivalent for this quaint expression — "What is your opinion as to the height of it 1 " He might as well have said that it signified " How many inches, ascertained trigono- metrically, does it span in a vertical direction 1 " The expression is always used in a quaint and half-ironical manner. For instance, a man will show a picture in flaming colours, and with glaringly gi'otesque figures, and ask " How's that for high 1 " Or he will ask the question after reading some absurdly grandiloquent passage in a speech or descrijition. Hub. Boston is commonly known in America as " The Hub" — shoi'tfor Hub of the Universe. (How's supposed to be known) in which lie all the vague possibilities man is ever ready to l)icture where ignorance or imiierfect know- ledge permits, is the true domain of religions aspirations in so far as they belong to emotional faich. We now propose to supplement those papers by a series showing in what bcnse. religion is the outcome of knowledge, and how the religion of every nation and of every .age has ever been the expression of the knowledge (such as it has been) of each nation and each age. We shall, in fact, strive to do for religion from one special point of view what Professor Drummond has striven to do for it from another. He has endeavoured to show that in the spiritual world there aie natural laws akin to those which the student of science has learned to recognise in the world of m.atter. We shall endeavour to show that the men of every age and nation have striven to embody in their religion sr.ch natural laws .as they knew or supposed they knew. In other words, we shall strive to show the eminently reasonable character of all religious .S3'stenis, nay, of each specific religious dogma — granted onlj' that men had lightly apprehended the signifi- cance of the facts of n.ature as seen by them and as they understood them. Wo may thus learn bow it has come to pass that certain doctrines have been almost universally accepted ; others limited to special races or to special times. We shall learn to distinguish what is probabl}' well founded from what is probably unsound in the religions of the human race — not by considering religious doctrines in them- selves, but by striving to understand on what ideas about natural facts or natural Laws they were originally based. And in this way the true bearing of science on religion will bo recognised. For few fcientific teachings have any direct bearing on religious doctrines ns actually developed, even when they may have the most decided and decisive bearing on the ideas out of which the development of that doctrine sprang. As the discoveries of astronomy h.ave no direct bearing on the doctrines of astrology, while fully inter- preting most of the facts on which those doctrines were originally based, so is it with the teachings of modern science in relation to nearly .all the doctrines of every religion the world has known. Science can seldom prove or disprove any dogma of religion, but science can in a number of instances s.ay confidently that this or that fact on which such and such dogmas were primarily based must be intei'- ]n'eted thus or thus — as it was interpreted by tho.se who first found in it the germ of some special religious teachintr, or (it may be) rjuitc otherwise. In such an inquiry science is working, without doubt, within its proper iield. For it is the special aim and pur- pose of science to interpret facts if it can, and to classify them (for future interpretation, perhaps) where it cannot. The student of religion will also heio be engaged on an infjuiry which leally bears upon religion : for he cannot but be interested in consideiing the origin of specific religious doctrines; and where ob.served facts or supposed facts and natural laws more or less clearly discerned have led (.as they alw.ays have led, first or last) to religious views, it cannot but interest him to inquire how far the observations were real or illusory, and in what degree laws really hold which men have supposed they had determined. The inquiry will extend to each one of those dogmas of religion to which Professor Drummond has striven to extend the idea of natur.al Law, but other matters (outside his sul ject) will be considered also in our discussion of religious views as the expression of men's knowledge, real or supposed, of nature and her workins;s. THE RELIGION OF THE ANCIENT BRITONS.* II. T is among the non- Aryan. prc-C'eltic dwellers in Britain that Druidlsra flourished, and became in large measure mingkHl with Celtic poly- theism, so that the elements of each are not easy of separation. C.o^sar says of it that it " is thought to have been invented in Britain, and to have been carried over to Gaul ; and at the present time those who wish to gain a more precise knowledge of the system travel to that country for the purpose of studying it."t The straightforward and interesting account which he gives of G.allic Dniid- ism, of the functions of the priesthood and character of the ceremonies, is therefore to be applied, with local modifications, to Britain. But wo must guard against giving high-sounding names and titles, and crediting philo- sophic qualities, to a religion so barbaric in its origin and essence as that of the earlier rtices of the.se islands, judging from analogy and from the dcscriiitlon of Tacitus and other writers, must have been. A good deal of speculation has been expended on the deriv.ation of the name Druid, the Irish word for which is dmoi, meaning a magician or sooth- sayer; but Profes.sor Rhys, after weighing the matter, and citing evidence concerning tree-worship, inclines to the old etymology drus, "oak," as the true one. Not only was that tree, as the emblem of Jupiter, .sacred among the Romans, who also called the acorns "juglans," i.e. " Jovis glans," the fruit of the god ; among the Greeks, in whose literature and legends there is frequent reference to the oak as sacred to Zeus, who, as the source of divina- tion, spake through the rustling leaves of the ssicred oaks at Dodona ; among the Scandinavians, as the tree of Thor ; and among the Teutons, as shown in the many vestiges of holy o ; ■whence F c . « D =B T> . ac. .-.

Join E A and draw D L perpendicular to A B, bi.secting A K in L (beaiuse AD^DC). Then since LD and AE are parallel and B L=^ A B 'BD = § BE=i Bo; the same result as by the " great engine." But the " great engine " did the work more easily.* The Saturdatj Ileview having displaj-ed its profundity thus effectively, proceeds in the following strain : — In tlie table of contents, we were astonished to find the heading " Elliptic Integrals," [In reality the heading is " Elliptic and Hyperbolic Integrals," but to have roentioned this would have baulked the S. R.'s attempt at sarcasm.] but on looking up the chapter found not a word about them, as ordinarily understood, but only a proposition about finding the area of an fllijise by inte- gration. Must we conclude that the author did not know what the phrase meant ? [The S. R. naturally leaves it to be understood that we must come to this distressing conclusion.] Now if I were given to betting, I would be prepared to offer a tolen^bly large wager that the writer of this critique (save the mark !) does not in the least know what an " elliptic integral," as commonly understood, really is, or why it is called an " elliptic integral," or for what purposes the .so-called " elliptic functions " were discussed by Legendre. The way in which he emphasises the word "ellipse" (for the italics are his) shows this clearly enough. Evidently that sarcastic emphasis would have come in quite as effectively if he had had to say that he only found a proposition about rectifying the arc of an ellipse by inte- gration— though such a proposition would have related unquestionably to " elliptic integrals " as commonly under- stood. The fact is that the phrase " elliptic integrals," as com- monly used, is a con^-enient misnomer. In the rectification of an ellipse (centre as origin of co-ordinates, major axis 1, and eccentricity e), we obtain the equation — f / i ga x^ s^\ A / — d X (where s represents the arc), and putting a;=sin 6, so that do: — cos, OdO, we get s=\^T. e de. * Here are two easj' problems which either the beginner in the Differential Calculus or the geometrician can solve: (I) Deter- mine the maximum cylinder which may be inscribed in a given sphere. (2) Determine the cylinder of maximum surface which may be so inscribed. Now the term " elliptic integrals " is applied conveniently, but not correctly, to expressions of the form, where ^/(x,X)dx X=^/ a + b.T + cx^ + dx^ + ex** d and e being not both equal to zero. Such integrals can be classified into others, of which all not expressible by algebraic, logarithmic, or inverse trigonometrical functions, have one of the three forms : — ^'^ J Vjl-c'sir^e ^"* J ^ {l-c^-sir?ed6 dd and (iii J(l+^ the integrals being all taken between the limitt-, 0 .and o. The second form is that already obtained for the rectifica- tion of the arc of an ellijise ; and for this rea.son, by no means a perfect one, these integrals are all, for convenience, called " elliptic integrals." But if mathematicians may for convenience call several orders of integrals " elliptic " because one among them really is elliptic, as appearing in dealing with the rectifica- tion of the ellipse, they are surely free if it suits their con- venience (as it did mine in the present case) to call certain integrals " elliptic " which are really elliptic, as appearing in dealing with the quadrature of the ellipse — especially if (as 1 did) they prevent all possibility of mLstake by com- bining with the term " elliptic," thus used, the term " hyperbolic " similarly used, because it relates to an order of integrals appearing when we are dealing with the quadrature of the hyperbola. I wanted a convenient heading for a chapter on integrals relating to the ellipse and hyperbola, so I called them " elliptic and hyperbolic integrals." I knew that on the one hand the readers for whom I was writing could not be in any way misled by this nomenclature, especially as the chapter itself sufficiently explained the use of the words. I was equally well assured that no mathematician acquainted with the technical (but scarcely correct) use of the phrase " elliptic integrals " could be for a moment misled, if by any chance he looked over my simple pages. And although the idea did occur to me that critics of the S. R. class — neither learners nor learned — might cavil, that did not in the lea.st trouble me. I knew that on the one hand I was certain to encounter cavillings of that .sort, and that on the other I should know well how to treat them, and shoidd even be able to apply them to a useful purpose, as I am now doing. That the notice I have been dealing with is feeble and spiteful may be explained by the fact that it appears in the paper called the Saturdai/ Review — by some (by others less euphoniously). Does this remark sound unmannerly '( For my own part, I think it does. I withdraw it. I was only trying an experiment. The S. E. says that the defects (invented) which it pretends to recognise in my two small and unpretentious books, " First Steps in Geometry " and "Easy Lessons in the Differential Calculus," "may be ex- plained by the fact that they consist of papers written for the magazine called Knowledge." I wanted to see how such a remark applied even to the Saturday Revikr might sound. 1 cannot thick that it sounds well. As for the remark thus rudely made by the S. R., it chances to be untrue — no very strange chance of late, when the S. R. is in question. The substance of the two books dealt with was not written for Knowledge, though it ap- peared in Knowledge. (The Saturday Review never could • If under the radical higher powers of x appear than the fourth, the integrals thence deducible are called " ultra-elliptic " or " hyper- elliptic." 202 KNOWLEDGE [July 2, 1888. be logical, even in its better days.) Both works were written long before Knowledge began its career. They were submitted by Messrs. Longmans to the Rev. Mr. Griffin, of O.spriuge, a Senior Wrangler of long standing and well known as a mathematician of great power. After carefully examining both works, he recommended Messrs. Longmans to accept them for publication, and accordingly an agreement was drawn up in regard to these two works, and this agreement — which lies before me as I write — bears a date preceding the Lssue of the first number of this magazine. The effort of the ,S'. 7?. to be disagreeable was well tiled, however. THACKERAY AND THE REVIEW." SATURDAY ERE is my Sat'iinhcy Revieiv, and in an American paper subsequently sent to me, I light, astonished, on an account of the dinners of my friend and publisher, which nre described as ' tremendously heavy,' of the conversation (which does not take place) and of the guests assembled at the table. 1 am informed that the proprietor of the Cornhill, and the host on these occasions, is ' a very good man but totally unread,' and that on ray asking him whether Dr. Johnson was dining behind the screen, he said, ' God bless my soul, my dear sir, there's no person by the name of Johnson here, nor any one behind the screen,' and that a roar of laughter cut him short. I am informed that I have touched up a contributor's article ; that I once said to a literary gentleman, who was proudly pointing to an anony- mous article as his writing, ' Ah I I thought I recognised your hoof in it.' . . . Then the graceful writer passes on to the dinners, of which it appears the editor of this maga- zine ' is the great gun, and comes out with all the geniality in his power.' Now suppose this charming intelligence is untrue. Suppose the publisher never made the remark beginning, ' God bless my soul, my dear sir,' kc, nor any- thing resembling it ? Suppose nobody roared with laughing. Suppose the editor of the Cornlnll M(iija:ine never ' touched up ' one single line of the contrilnition which bears the mark of his hand ? Suppose he never said to any literary gentle- man 'I recognised your hoof in any periodical what- ever? . . .

[This paragraph, as it stands, would give an unfair idea of Thackeray's strictures. The Saturday I'l'vieiv in 1860 was a powerful paper. Those were the best days mentioned by Matthew Arnold in his pi'aise of the American paper The Nation. In the article quoted Thackeray speaks of the Saturday Review as piquing itself (" and justly and honourably in the main ") on its gentlemanly as well as its literary character. It was then, moreover, usually manly, though it was always chai'acterised by the weakness indi- cated by declining ever to correct or admit mistakes, to which, in common with all things human, it was liable. We find even a man of science like Darwin, though remarking with reference to a critique in its pages that " One cannot expect fairness in a reviewer, so I do not com- plain &c.," I'ecognising real worth in a Saturday Review criticism of his " Origin of Species."
