THE first meeting of the American Association for the Advancement of Science was held in the City of Philadelphia, September 20th, 1848. There were then 461 members of the Association, but we have no record of the number in attendance. The second Philadelphia meeting was held September 3, 1884. The Association then numbered 1,981 members and the attendance was 1,261, including 303 members of the British Association for the Advancement of Science and nine other foreign guests. The third Philadelphia meeting was held December 27 to 31, 1904. The total membership was nearly 4,000 and the registered attendance numbered 588 members and 104 members of affiliated societies, making a total registered attendance of 692 members. From 200 to 400 did not register, so that we may safely conclude that the total attendance was at least 890, and perhaps very much larger.* The present meeting is, therefore, the third largest in point * We estimate the number of scientific men in attendance to have been in the neighborhood of 1,200. 240 members of the American Chemical Society were registered, but only 75 for the Chemical Section of the Association. There were nearly 100 members of the American Psychological and Philosophical Associations in attendance, very few of whom registered. The conditions were probably similar in other sciences.—ED. 2 SCIENCE. of numbers since the year 1884. While numbers are not an index of the value of a meeting, they do show the amount of interest taken in its proceedings, and from that standpoint we may conclude that the third Philadelphia meeting was a success. It was also a suecess from the standpoint of number of papers read‘and the general interest in the papers, as well as in all of the proceedings of the association. Tabulating the members according to the sections for which they registered, we find the following numbers: Section. “Ay nie. chin stewie reno 57 Section [By 244 oe Oa corte eee 66 Section Gs.

These figures show that where a national scientific society met in conjunction with the association, the corresponding section was large and where a national scientific society did not meet, the attendance was very small. This would seem to indicate that members of the association prefer to attend a meeting of the national society rather than the meetings of the association unless the two meet together. The University of Pennsylvania placed its halls and laboratories freely at the dis- posal of the association and each day fur- nished a lunch to the members. The asso- ciation has never received more careful at- tention than it received at this meeting. A vote of thanks was extended to the uni- versity, the details of which will be found later on in the report. In former years a daily program has been published, showing the papers to be [N.S. Vor. XXI. No. 523. read that day and giving a list of the mem- bers in attendance. This has always been a severe drain upon the resources of the association and it was decided this year to use but one program, which was dis- tributed to members on the first day papers were read. This single program seemed to answer its purpose as well as the daily programs have in the past, except that many members missed the lists of those in attendance. If some method can be de- vised by which members may know who are present, there can be no objection to the single program. Since the last meeting of the association 377 members have been elected; although this is not as large as the number elected in previous years, yet it shows a steady growth and a growing interest on the part of the public in the work of the association. There has always been great difficulty in getting reports of the association and its work published in the daily papers, except those in the city where the meeting is held. This year the Committee on Policy of the Association instructed the permanent seere- tary to appoint a press secretary. The permanent secretary appointed Mr. Theo- dore Waters. Reports of the meetings were prepared each day and sent to most of the prominent newspapers of the coun- try. It was impossible to make the re- ports as full as desired, as some of the members of the association who read papers did not give their abstracts to the press secretary, although they were requested to do so. If the readers of papers will take pains to see that their abstracts are in the hands of the press secretary, entirely satis- factory reports can be sent out in future. It is greatly to be desired that the press of the country give some attention to the meetings of our greatest scientific society. The two questions of general interest were the time of meetings of the associa- tion and our relation to the affiliated so- JANUARY 6, 1905.] cieties. These questions have been actively discussed before, but they do not seem to be definitely settled in the minds of many. The sections which have been in the habit of giving excursions and those who study objects out of doors, prefer a summer meet- ing, but it seems that a large majority of the association is in favor of the winter meetings, as the general committee unani- mously decided to hold the next meeting during the winter. The committee on policy reported that it had considered this matter and would recommend that this general committee request the next general committee to hold a summer meeting in Ithaca during the summer of 1906. The suecess of this meeting will undoubtedly have a great deal to do with settling the question of summer meetings. There seems to be no objection on the part of the association to holding two meetings each year, one during the winter and one during the summer. The expense involved would be considerable, but the association can bear it and perhaps the best solution of the problem will be two meetings. This is a question which the future must decide. AFFILIATED SOCIETIES. The following Affiliated Societies held sessions in conjunction with the associa- tion: American Alpine Club. The American Anthropological Association. The American Chemical Society. The American Folk-Lore Society. The American Geographers’ Association. The American Mycological Society. The American Philosophical Association. The American Physical Society. The American Psychological Association. The American Physiological Society. The American Society of Naturalists. American Society of Vertebrate Paleontologists. Association of American Anatomists. The Association of Economie Entomologists. The Astronomical and Astrophysical Society of America. SCIENCE. The Botanical Club of the Association. The Botanical Society of America. The Society for Plant Morphology and Phys- iology. The Society for the Promotion of Agricultural Science. Sullivant Moss Chapter. The Wild Flower Preservation Society of America. The Entomological Club of the Association. Eastern Branch of American Society of Zoolo- ogists. The Fern Chapter. The Geological Society of America. The Sigma XI Honorary Scientific Society. The Society of American Bacteriologists. The Society for Horticultural Science. The Southern Society for Philosophy and Psy- chology. The Pelee Club. The association is still pursuing the policy of encouraging the great national societies to meet at the same time and place with it. The association secures rooms, provides accommodations, makes ar- rangements with hotels and railways and in all points takes charge of general arrange- ments without expense and without trouble to the affiliated societies. Nearly, if not all, of the societies meet in perfect harmony with the respective sec- tions. In almost every case the sections have charge of the general session in one half of the day and the affiliated societies have charge of the meetings during the other half of the day. Thus there is no friction and papers are presented before both bodies, while there is the additional advantage of a larger attendance at both the section and the society. It is hoped that this arrangement will appeal still more to the national societies until all of them enter into this arrangement with the association. The attendance of the members of the societies this year indicates that they are willing to cordially cooperate with the as- sociation and turn out in large numbers to attend these joint meetings. There is + SCIENCE. nothing in the arrangement which prevents an affiliated society holding a _ separate meeting at any other time of the year if it chooses. The first session of the fifty-fourth meet- ing of the American Association for the Advancement of Science was called to order in College Hall Chapel, University of Penn- sylvania, Philadelphia, Pa., at 10 a.m., Wednesday, December 28, 1904, by the retiring president, Dr. Carroll D. Wright. Dr. Wright introduced the president-elect, Dr. William G. Farlow, who made a brief address. "Provost Harrison, of the Univer- sity of Pennsylvania followed with an ad- dress of welcome. President Farlow thanked Provost Har- rison for his words of welcome and then asked the general secretary to make the announcements from the council. Mr. Howe (general secretary) : The Council has voted to extend the privileges of associate mem- bership for this meeting to members of the local committee, residents of Philadelphia and vicinity and to members of the affiliated societies. The following committees have been appointed to serve during this meeting: Committee on New Members: The permanent secretary and the secretary of the Council. Committee on Fellows: The general secretary and the vice-presidents of the sections, Mr. Howe, chairman. Committee on Grants: The treasurer and the vice-presidents of the sections, Mr. R. 8. Wood- ward, chairman. It has been decided to hold sessions of the Council at nine o’clock in the morning, but there will be no other general session until Saturday morning at ten o’clock. Dr. Calvert, secretary of the local com- mittee, made some announcements in be- half of that committee in regard to the arrangements which had been made for the comfort and convenience of the association. After the adjournment of the general session the several sections were organized in their respective rooms. In accordance with a suggestion from the committee on the policy of the asso- (N.S. Vou. XXL. No. 523. ciation, the vice-presidential addresses were scattered throughout the week, instead of being given on the same date. It was thought best to have in addition to a vice-presidential address, one or more papers of general interest, which would fol- low the address, thus taking up the greater part of that session. The general program of the week was as follows: GENERAL EVENTS. The council of the association met daily from December 28 to December 31, inclusive, at 9 A. M., in the auditorium, Houston Hall.

The following amendment to the econ- stitution which was proposed at the St. Louis meeting, favorably acted upon by [N.S. Vor. XXI. No. 523. the council and reported to the general session, was adopted: Amend Article 34 by the omission of the words ‘‘On the election of any member as fellow, an additional fee of $2 shall be paid.’’ The proposed amendment of article 4, line 2, to read ‘‘The members of at least one year’s standing, who are professionally engaged in science and have, by their labors, aided in advancing science’’ was unfavorably reported upon by the commit- tee on policy. POLICY OF THE ASSOCIATION. The council appointed Mr. R. S. Wood- ward permanent chairman of the commit- tee on policy of the association. The council voted that the committee on policy of the association be requested to exercise a general executive control of the preliminary arrangements for meetings and of the publications, subject to the control of the council. The committee on policy of the associa- tion reported the following resolutions which were adopted: ‘““That the permanent secretary be au- thorized to offer sets of the back volumes of the Proceedings to libraries, which shall be approved by the committee of the associa- tion appointed by the president.’’ ‘“That the publishers of ScteNcE be re- quested to announce prominently that eut copies will be sent to members who request it:?? ‘“That the committee recommends as members, and if they become members, nominates as fellows, members of the na- tional scientifie societies not now members of the association in eases in which the national scientific society has a qualifica- tion for membership equal to that of the qualification of the association for fellow- ship. The following societies are accepted as having such qualifications : January 6, 1905.] The American Society of Naturalists. The American Philosophical Society. The American Academy of Arts and Sciences. The Association of American Anatomists. The Association of American Physicians. The Association of Pathologists and Bacteriolo- gists.

Binding to be in cloth or boards, as the treasurer and secretary may think proper. Dr. W. H. Hale introduced the following resolution, which was adopted: Resolved, That the American Association for the Advancement of Science hereby extends its hearty congratulations and best wishes to Dr. Martin H. Boye, a founder of this association, and the only surviving founder of the parent association, that of American Geologists, after- wards called the American Association of Geolo- gists and Naturalists, which was founded in this city in 1840, Dr. Boye being present at that time, as well as at the founding of the American Asso- ciation for the Advancement of Science in 1848. Professor C. M. Woodward introduced resolutions thanking the officers of the Uni- versity of Pennsylvania and other institu- tions that had entertained the association and these were unanimously adopted. At the meeting of the general committee, Friday evening, it was decided to hold the next meeting in New Orleans, the work of SCIENCE. if the association to begin Friday, December 29, 1905.

Like the Japanese, the division com- manders, looking well to their supplies of ammuniticn (7. é@., correct theories) and their daily rations (7. e., materials of con- struction and shop practise), push forward now at one point and now at another, cap- turing hill after hill, now on the right, now on the left, and now in the center. The army of science never retreats; it forever forees back the frontiers of darkness, and solves problem after problem from the end- less list of secrets with which the store- houses of nature are filled. It is a glorious thing to belong to this engineering army, to rejoice in its triumphs and to share in its rewards. Its success is not accidental ; its triumphs are not matters of chance. Iingineering blood always tells. Just as we train our best soldiers and sail- ors at West Point and at Annapolis; and as our appliances at military and naval schools keep pace with the arts of war on land and sea; so our schools of engineering, if they are up-to-date institutions, keep pace in the theories they teach and in the laboratories they equip with the best en- Every advance at the front (to resume my simile) means an ad- vance of all supplies and in the enlisting and training of recruits.

In short, our schools of engineering must know the lines of engineering progress. I am well aware that I shall not be able to touch upon many of the important mat- ters which my subject is sure to bring up, and I can not expect to take them in the order of their importance. Probably no rank. [N.S. Von. XXI. No. 523. two of us would agree upon their relative importance ; one’s environment has so much to do with what lies just beyond his hori- zon; so I doubt not you will supplement my statement with most interesting and valuable suggestions. THE UTILIZATION OF WASTE ENERGY. While much has been done and much more is doing at waterfalls and river rapids, large and small, the work of saving the energy which now runs to waste has but. just begun. When the great water- falls are utilized the rapids will rémain. We are lost in wonder when we calculate the possibilities. Measure the volumes which rush over the ‘Sault St. Marie,’ as the waters of Lake Superior drop to the level of Lake Huron; and then again put your measuring rods into the vastly greater volumes which plunge and rush from Lake Erie to Lake Ontario; and still again through the rapids of the St. Lawrence to the sea level. At every vantage ground, the work of utilization has begun and na man now living will see that work stop. Turn next to smaller streams and mountain torrents—what fields open up to the hy- draulie and electric engineers! Mountain reservoirs will serve the triple purpose of preventing destructive floods, of saving the energy for useful work and of aiding irri- gation. At every count the doors open wide for the best of engineering enterprise and the best of engineers, hydraulic, me- chanie, electric, irrigation, and the echo of each department must be heard in the en- eineering lecture-room and laboratory. The electric transformer has made the transmis- sion of energy possible from mountain slopes to far cities, and has unlocked be- wildering amounts cf energy at thousands of points deemed hitherto inaccessible. No one ean see far into the future, but we ail easily see the dawn of a new era of energy saving. The streets of this city may y-t JANUARY 6, 1905.] be lighted by the energy which now runs to waste at Niagara. In St. Louis we look to the slopes and canyons of the Rockies for our supply of sweet, wholesome water—we may yet look to the same regions for the energy to drive our cars and run our mills. COMBUSTION ENGINES. The clumsy steam-engine, with its waste- ful furnace, its huge boiler and chimney, is doomed. It has done great work in producing available energy and in wasting still more. It has played a most important part in modern civilization, and it deserves well at our hands, but nothing ean stay the deeree of progress. Sentence will soon be pronounced, but the day of execution has not been set. I never expect to see the day when steam power plants will cease to exist, but my children will see such a day. Think for a moment of the present com- plicated, indirect method of procedure for converting the energy stored in coal into mechanical energy in a moving piston or a revolving shaft. Coal and air are fed into a furnace where combustion converts them into great volumes of a mixture of hot gases. The greater part of the heat and all the volume of these gases escape through the chimney; a small part of the heat only is drawn off by the steel shell and tubes of a boiler and transmitted to a body of water, which is thereby trans- formed into steam. The steady generation of steam against high pressure, added to its expansion as the pressure is reduced, enables it, when conducted to a cylinder, to drive a piston or revolve a shaft, thereby producing mechanicai power. The clumsi- ness of the operation is equalled only by its wastefulness, which varies from 88 per cent. to 95 per cent. The problem to-day is: What 1s the most direct and most economical road from coal to moving machinery? Engineers are at- SCIENCE. 9 tacking this problem on all sides, and at- tacking it suecessfully—gas-engines, and combustion-engines of various sorts bear witness. The future prime-mover will burn (not explode) its fuel in the working eylinder, and the piston will be driven, first by the products of combustion as their volume inereases, and secondly by their ex- pansion against a diminishing resistance. I predict great things of the Diesel motor. Originally it was designed to burn powdered coal mixed with hot compressed air; but erude petroleum was found to be preferable. So long as oi! flows abund- antly from wells, oil will generally be used, but powdered fuel, native or prepared, will doubtiess prevail ultimately. The economy and directness of the combustion motor can not be excelled, and when a few years of study and experiment have been applied to the work of simplifying the mechanism (it was a century from James Watt to a triple-expansion Corliss), we may expect it to come into general use for all great central power stations. The vitality of the steam-engine is due to-day to the mechanical perfection of its design. Its simplicity is marvelous. It is started and stopped with the greatest ease and it almost takes care of itself. The invention of the steam turbine has prob- ably given to the furnace and steam-boiler another lease of life. The wonderful adaptability of the turbine for electric gen- erators is something which was not an- ticipated. Will not some one design and construct a combustion engine which shall consume continuously oil and compressed air, thus maintaining a high pressure in a gas chest and driving a turbine with the products of the combustion used expansively as is now done with steam? The proposition is an attractive one, both for the lecture room and for the engineering laboratory. It is sufficient now to eall attention to its pos- 10 : SCIENCE. sibility, and to indicate a point for study and progress. It will not be amiss for me to quote the figures given me by the engineer in charge of the Diesel engines which drove. the generators for power and light in the ‘Tyrolean Alps’ at the late world’s fair in St. Louis. These engines, three in number, of 225 horse power each, were the cbserved of many observing engineers during the seven months of the fair. The assistant engineer in charge kept daily records of the work done, and fuel used, and kindly gave me a sample of his reports. The details are extremely interesting. The work was measured at the switchboard, no allowance being made for loss of energy in the engine, air pump and generator. The total work of the three engines between noon and midnight was 2,768.5 K.W.H. This is equivalent to 3,711 H.P.H. Total fuel used (Indiana oil), 266 gals. Fuel per 100 K.W. hours, 9.58 gals. Fuel cost in car-tank lots, 3c. per gal. Cost per 100 K.W.H., $0.287. Cost of the day’s fuel, $7.98 or 2.15 mills per ishieniale Thus one cent paid for the fuel for one- horse power for four hours, forty minutes. The three engines worked under about two thirds of a full load and used three gallons of lubricating oil during the day. The above figures seem to me little less than remarkable. While still wasteful, as nature measures energy, these engines are several times as efficient as the better styles of ordinary steam-engines. Doubtless they lack sim- pheity and the certainty of action which comes from experience and close study; but I can not help feeling that the road to the future ‘prime mover’ runs hard by the construction shops of an internal-com- engine. Let studerts and pro- fessors take warning. bustion [N.S. Vou. XXI. No. 523. ARTIFICIAL CENTERS OF POWER. One of the most important openings for future engineering enterprises is the estab- lishment of large power centers, not only where water power is available, but where iuel is abundant as well. Take, for example, the vast coal mines in the vicinity of the city of Philadelphia and those in the vicinity of St. Louis. In each case the puwer for industrial estab- lishments and all kinds of moving ma- chinery, large and small, in use in the city, including the street cars and the rolling stock on all roads, can well be furnished by electrical currents from large gcnerating establishments near the mines. Add to the above the establishment of gas works sufficiently large to furnish all the gas needed for illumination, for gas-en- gines, for heating and cooking purposes in a great city. In the ease of St. Louis those gas works should be near the extensive coal mines of Belleville and other coal- producing regions only a few miles from the eity. The effect of these two great steps for- ward upon the physical and sociological characteristics of a city can hardly be over- estimated. The ultimate economy and con- venience of such installations are enough to justify them. We have yet to learn how cheaply fuel gas and electric currents can be furnished to large concentrated groups of consumers. But omitting all questions of mere financial economy, what a saving in health, beauty and enjoyment! The Lon- don fogs which we hear so much about are produced largely by London smoke, and the prevention of smoke will to a very great extent be the prevention of the fog. _I look forward to the day when, instead of a small voleano of smoke from a brick crater above every house, St. Louis will have all its heating and cooking done by gas, and all power will be furnished by electric cur- rents, or by gas and combustion-engines, JANUARY 6, 1905.] both gas and electricity coming from the gas works and power plants at the mouths of the coal mines in Illinois. What an era of cleanliness and comfort this presages! This era of cleanliness will be brought about by the engineers. Hence engineer- ing education must see to it that engineer- ing students are prepared for their high mission. The proposed ‘Million Club’ of St. Louis bears no comparison with a pos- sible ‘Clear Sky Club.’ The former pro- poses to seduce 250,000 non-resident smoke- makers imto joining the 750,000 smoke- makers already resident in St. Louis, there- by making smoke enough to shut out the sun entirely (they almost did it during a whole week last November). The ‘Clear- Sky Club,’ on the other hand, will propose to eliminate all smokers by sending coal- burning power plants to the mines, thereby leaving the city so clean and beautiful that 250,000 lovers of pure air, clear skies and godliness will seek homes among us of their own accord. The elimination of smoke, soot and ashes will make St. Louis abso- lutely bright and clean, and similar im- provements here would go far towards pro- ducing the same beneficial results in the city of Philadelphia. Already our cities have, or are making arrangements for, an abundant supply of pure water. This has been and still is a great branch of engineer- ing, and it deserves an important place in our schools of engineering. We must next provide pure air and a clear sky. These steps forward involve no very ereat addition to our engineering knowl- edge, but they give opportunity for engi- neering enterprises, and they show most clearly how essential cooperation is in such work. Large power plants and extensive gas works require much private capital, unless we fly to the extreme of public ownership. The economic construction of large power plants and gas plants; the lay- ing of pipe lines and an unprecedented SCIENCE. i amount of electric cables, all or nearly all underground, constitute a great field and furnish great engineering opportunity. TH PURIFICATION OF RIVERS. We have nearly reached the limit in river pollution. The public welfare will soon make an imperative demand for a halt. < 67449 1 Vn The percentage probable error of go 281808 Ee S/N aes After considering the subject of multiple contingency and its relation to multiple nor- mal correlation the author proceeds to’ give some illustrative examples showing something of the sort of problems to which the method may be applied, and also how it is to be used in practise. The examples include (a) the correlation between father and son in respect to stature, (b) color inheritance in grey- hounds, (¢c) fraternal resemblance in hair color in man, and (d) the correlation between father and son in respect to occupation or profession. The net results brought out by the analysis and confirmed by the numerical illustrations may best be stated in the author’s own words: [N.S. vou. XXI. No. 523. “With normal frequency distributions both contingency coefficients pass with sufficiently fine grouping into the well-known correlation coefficient. Since, however, the contingency is independent of the order of grouping, we conclude that, when we are dealing with al- ternative and exclusive sub-attributes, we need not insist on the importance of any par- ticular order or scale for the arrangement of the subgroups. This conception can be ex- tended from normal correlation to any dis- tribution with linear regression; small changes (%. e., such that the sum of their squares may be neglected as compared with the squares of mean or standard deviation) may be made in the order of grouping without affecting the correlation coefficient.” These results “are not so fruitful for practical working as might at first sight appear, for they depend in prac- tise on the legitimacy of replacing finite in- tegrals by sums over a series of varying areas, where no quadrature formula is available. If we, to meet the difficulty, make a very great number of small classes, the calculation, es- pecially of the mean square contingency, be- comes excessively laborious. Further, since in observation individuals go by units, casual individuals, which may fairly represent the frequency of a considerable area, will be found on some one or other isolated small area, and thus increase out of all proportion the contingency. The like difficulty oceurs when we deal with outlying individuals in the case of frequency curves, only it is immensely ex- aggerated in the case of frequency surfaces. It is thus not desirable in actual practise to take too many or too fine subgroupings. It is found, under these conditions, that the cor- relation coefficient as determined by the prod- uct moment or fourfold division methods is approximated to more closely in the ease of the contingency coefficient found from mean square contingency than in the case of that found from mean contingency. Probably 16 to 25 contingency subgroups will give fairly good results in the case of mean square con- tingency, but for each particular type of in- vestigation it appears desirable to check the number of groups proper for the purpose by comparing with the results of test fourfold JANUARY 6, 1.95.) division correlations. Under such conditions it appears likely that very steady and consist- ent results will be obtained from mean square contingency.” In the caleulation of contingency coefficients the present writer has found that the follow- ing procedure saves much time and _ labor. The value of the independent probability r,,, for each compartment of the table is obtained by the use of a Thacher calculating instru- ment (Keuffel and Esser). With this instru- ment one can read directly to four or five figures the values of any expression which can be put into the form ax/b, where a and b are constants and x is a variable. Since y,, for any compartment equals (n,-m,,)/N for that compartment, it is evident that by taking either n, or m, as the constant, it will only be necessary to make as many settings of the instrument as there are rows or columns in the table. Having obtained the y,, quanti- ties, the sub-contingencies (n,,,— y,,,) may be written down directly, squared from Barlow’s tables, and divided by y,,, with an arithmom- eter or with Zimmermann’s or Crelle’s multi- plication tables. The remainder of the caleu- lations necessary to obtain the mean square contingency and the whole of the calculations for the mean contingency, and their respective coefficients are, of course, easily performed. Proceeding in this way, the calculation of con- tingency coefficients, even though several ex- perimental groupings are made, has been found to take but comparatively little time. The noteworthy features of this method of contingency are found in that it, in the first place, broadens and illumines the whole theory of correlation, and in the second place, brings within the range of biometrical investigation a large series of problems to which it has hitherto been impossible to apply exact meth- ods. One ean but feel that this memoir, like so many of the others which have preceded it in the series, marks a definite and funda- mental step in advance in the steady progress of the science of biometry. Raymonp Peart. ‘GLUCINUM’ oR ‘ BERYLLIUM.’ SoME years ago the question of choice be- tween the two names ‘glucinum’ and ‘ beryl- SCIENCE. 30 lium’ was gone into quite carefully by Pro- fessor F. W. Clarke and also by the committee appointed by the American Association on the Spelling and Pronunciation of Chemical Terms, and the conclusion was arrived at that the name ‘glucinum’ should be used on the ground of priority. In Science for Decem- ber 9 Dr. Charles Lathrop Parsons has stated his grounds for preferring the name ‘ beryl- lium.’ Dr. Parsons is, thanks to his biblio- graphical work on the element in question, thoroughly informed in its literature, but the arguments adduced by him would seem to lead to a conclusion diametrically opposed to that which he has drawn. It was obviously the privilege of Vauquelin, the discoverer of the element, or rather its oxid, to name it. This he never did, but con- tented himself by speaking of it at first as ‘la terre du Béril,’ that is, the earth in beryl. At the close of Vauquelin’s first paper the editors of the Annales added a note signed ‘ Redac- teur’ in which they propose the name ‘ glu- It was of course well known that Guy- ton and Fourcroy were the editors. Vauque- lin’s second paper in the Annales was evi- dently prepared at the same time as the first, or at least before the second was in print. In his third paper, some weeks later, as Dr. Parsons admits, Vauquelin actually adopted the term ‘ glucine,’ prefacing its use with ‘on a donné le nom de glucine.’ The paper in the Journal des Mines was apparently prepared at the same time as the first two papers in the Annales and before the appearance of the sug- gestion of Guyton and Fourcroy, but at its close occurs the note which Dr. Parsons has quoted. In this he states that Guyton and Foureroy have advised him to call the new earth ‘glucine’ and while he evidently does not think the name the best that could have been chosen, he clearly acquiesces in the sug- gestion of the two great authorities and says “Cette denomination sera assez significante pour aide le mémoire.’- Finally, as seen above, in his third paper, he adopts the name. As far as priority goes, the argument in favor of ‘beryllium’ would seem to be that probably Vauquelin would have given the earth some other name had he ventured to dissent from cine.’ 36 SCIENCE. Guyton’s authority, and it is probable that he would have liked to name it ‘ beryllia.’ All of which may be quite true, but actually he did not do it. As regards the German use of ‘ Berylerde’ it was merely at first the natural translation of Vauquelin’s expression ‘la terre du Béril,’ which, as we have seen, he used in no denom- inative sense. If the generally accepted rules of priority have any weight ‘ glucinum’ is the only term to be used for the element. As regards usage, the case is hardly quite as bad as Dr. Parsons seems to think, since the index to the Journal of the Chemical So- ciety (London) for 1903 gives ‘ Beryllium, see glucinum.’ With French, English and Amer- icans using ‘glucinum,’ we can afford to let the German journals cling to ‘beryllium’ a little while longer. Incidentally, what shall we do when the Germans insist on kalzium, kolumbium, karo- linum, zerium and zesium, or will it be keesium ? Jas. Lewis Howe. WASHINGTON AND LEE UNIVERSITY, December 12, 1904. BOTANICAL NOTES. THE STUDY OF FIBERS. Tre book (‘ The Textile Fibers, their Phys- ical, Microscopical and Chemical Properties ’) prepared by Dr. J. M. Mathews, and recently published by John Wiley, should make the study of textile fibers somewhat easier by stu- dents and practical operators. It covers nearly three hundred pages of neatly printed text, illustrated by sixty-nine cuts, in which the author has presented the whole matter in a most helpful way. There is first a use- ful classification of fibers, followed by deserip- tions and discussions of those which enter into fabrics. Some of these fibers are, of course, of animal origin, as wool, hair and silk, and to these are given about ninety pages. The remainder of the book is devoted almost wholly to plant fibers, and here the treatment is especially clear and helpful. The origin, varieties, physical and chemical properties of cotton, and mercerized cotton, are discussed in as many chapters. Linen is given another chapter, while jute, ramie, hemp and several [N.S. Vou. XXI. No. 523. other fibers of minor importance are disposed of in another chapter. An interesting chapter for the general reader is the one on artificial silks, the processes for the production of which “have been attended with a considerable degree of success.’ It is said that artificial silk ‘ has become a commercial article, and is used in considerable quantity by the textile trade.’ Of these artificial silks there are four general kinds, viz: 1. Pyrozylin silks, made from a solution of gun cotton in a mixture of alcohol and ether. 2. Fibers made from a solution of cellulose in ammoniacal copper oxide or chloride of zine. 3. Viscose silk, made from a solution of cellulose thiocarbonate. 4. Gelatin silk, made from filaments of gelatin rendered insoluble by treatment with formaldehyde. Most of the artificial silk is of the first variety, the manufacture of which is carried on in England, Germany, France and Switzer- land. “The fibers are formed by forcing the ether-aleohol solution of pyroxylin through glass capillary tubes, and winding them on frames. As the solution is very viscous it re- quires a pressure of forty-five atmospheres to discharge it through the capillary openings.” A STUDY OF COMPARATIVE EMBRYOLOGY. THE comparative embryology of the Cucuwr- bitaceae (Gourd Family) has been studied by Dr. J. E. Kirkwood, the results of which ap- pear in the Bulletin of the New York Botan- ical Garden (No. 11, 1904). After an instructive historical introduction, the organ- ogeny of representatives of the five tribes (Fevilleae, Melothrieae, Cucurbiteae, Sicyo- ideae, and Cyclanthereae) is summarily de- scribed, and this is followed by a quite particular examination of the embryo-sae in sixteen genera distributed among the five trikes. Twelve fine plates of 166 figures add much to the value of this portion of the paper. In a closing discussion the author finally con- cludes that ‘in most points the differences between the Cucurbilaceae, and other sym- petalous families are more striking than the similarities.’ The paper closes with a bibli- JANUARY 6, 1905.] ography including 89 titles. It constitutes a valuable addition to our knowledge of the embryology of a family whose place in the system of plants is still in doubt. A HELPFUL BULLETIN. Tue office of experiment stations of the United States Department of Agriculture has issued a bulletin (No. 2) consisting of an outline of a lecture on ‘ Potato Diseases and their Treatment,’ for the use of farmers’ insti- tute lecturers. It was prepared by F. C. Stewart and H. J. Eustace, of the New York Experiment Station. It contains summaries of our knowledge of the most important dis- eases which affect the potato in the United States. The descriptions are given in non- technical language, and ought to convince every botanist of the possibility of treating quite difficult subjects in plain English. Fol- lowing the description of diseases, is an ad- mirable chapter on spraying and other pre- ventive measures. Protessor RUSSELL H. ere eek iar 3 Radioactivity and Matter.

ACADEMIC IDEALS.* Tue beginning of an academic year calls up at once the lighter thoughts of pleasing associations and the graver thoughts of in- spiring obligations. Here on the table- land of intellectual life youth and age meet to labor for a season in the fields of knowledge and discovery. The confident optimism of youth seeks to be chastened by the gentle admonition of experience. Youth imparts its buoyancy to age, age im- parts its wisdom to youth, and both are kindled by the glow of elevating aspira- tions. It is a time, therefore, for a blend- ing of our lighter and our graver reflec- tions. Being delegated for the moment to speak to and for this academic body, it has seemed that some considerations on academic ideals might serve to awaken thought and to arouse zeal appropriate to the occasion. ° In the abstract, however, this would appear to be a delicate and a difficult subject; delicate because of diversity of sentiment, and difficult because of diversity of judg- ment, amongst those best qualified to speak, as to what academic ideals are, or as to what they should be. Hence it may seem fitting at the outset to suggest appli- cation to the views here set forth of the Soeratic caution that they ean hardly be exactly as represented, if not the more sweeping caution of Mareus Aurelius— ‘Remember that all is opinion.’ But the delicacy and the difficulty of the subject * Address read on the occasion of the opening exercises of Columbia University, September 28, 1904. 42 SCIENCE. are probably more apparent than real to us; for this is a university assembly, and it is one of the highest functions of a uni- versity to examine the various aspects of debatable questions without suppression of eandor and without loss of humor. The typical American university of our time is a complex organization which has erown up rapidly from the typical Amer- ican college of a half century ago. It has its undergraduate, its professional and its post-graduate schools, as we see them in Columbia University to-day. It has a heterogeneous aggregate of students ani- mated: by a great variety of aims and pur- poses. Its curricula embrace courses of study and research quite unknown to the educated public of thirty or forty years ago; and its degrees recognize professions quite unheard of before the middle of the nineteenth century. Moreover, the modern American university has broken to a large extent with custom and tradition. It is an institution characterized by intellectual agitation, by adjustment and readjustment, by construction and reconstruction, the end of which is not yet in sight. This complex organization is the resultant of the more or less conflicting educational activities of It is a resultant due in part to world-wide influences; it expresses a generalized academic ideal. Whatever may be our inherited prej- udices or our calmer judgments, the attain- ment of this ideal must be regarded as a remarkable achievement. Here, for ex- ample, in this institution, we find all kinds of subjects of study, from the most ancient to the most modern, from the most prac- tical to the most theoretical, from the most empirical to the most scientific, from the most materialistic to the most spiritualistie, all on a plane of intellectual equality and all equally available to those fitted to pur- sue them. Little surprise is manifested at the close juxtaposition of a professor of our times. [N.S. Vor. XXI. No. 524. metallurgy and a professor of metaphysics, and it has actually been demonstrated that professors of poetry and professors of physics can dwell in peaceful activity un- der the same roof. Here too the ten or a dozen faculties and the various student bodies mingle and intermingle in a spirit of cooperation and mutual regard almost unknown outside, and hitherto little known ‘within, the academic world. The mere atmosphere, then, of a modern university must energize and elevate all those who come within its influence. But the domain of this atmosphere is not bounded by academic walls. It is not a limited medium within, but is actually a part of, the unlimited medium of the intel- lectual world; for the modern university has broken also with custom and tradition in allying itself closely with the external world of thought. Through interaction of the intramural and the extramural spheres of thought the instructor and the student are kept face to face with the vantage ground of contemporary life, whence they may look forward as well as backward. The modern university is an institution of learning in the full sense of the word; an institution wherein instructors teach students, and wherein, reciprocally, to a very important degree, students teach in- structors; for that instructor is fossilized who does not learn more per year from his students, if they are worthy of the name, than they learn from him. Together they work diligently not only to become ac- quainted with the known, but still more diligently to penetrate the secrets of the unknown. Among them there is a senti- ment that condemns alike the instructor who would impart knowledge by the meth- od of the rotary calabash, and the student who, with saturnine stolidity, would ab- sorb only the information poured into his ears. Dwelling thus at a university, not apart from, but actually in, the world of _—— LOLCat I Ey. a a ca he 7) ee icc eieeletenineinaldteenttee ee Eee ee JANUARY 13, 1905.] contemporary thought, students may best fit themselves for the- world of contempo- rary life; and while they may justly esteem it a great privilege to graduate from an historie college, or from a professional school of international reputation, they should esteem it a far higher privilege to eraduate from a great university. It should be observed also that the re- sultant ideal which has been attained in our best universities is not fixed but pro- eressive, not inflexible but subject to im- provement. It is a development whose sources are seen in the earliest civilizations, whose growth was dimly perceived during the middle ages, and whose conscious ap- preciation is a realization of the century just past. The method which characterizes this development is the method of science. It dates essentially from the epoch of Gali- leo and Huygens. It rose to a maximum of brillianey in its interpretation of ma- terial phenomena during the epoch of New- ton and Leibnitz, and during the epoch of Laplace and Lavoisier; and it has recently illuminated: a new domain through the labors of Darwin and Spencer. Galileo, Newton and Laplace gave us a system of the inorganic world; Darwin and Spencer have given us a system which includes the organic world as well. The method of science has permeated all regions of thought and animated all of the commercial, industrial, political, social and religious activities of men. Whether we welcome it, deplore it, or indifferently ac- quiesce in it, the fact seems undeniable that the method of science and the doctrine of evolution are the most effective sources of the intellectual enterprise of our day. Through anthropology this method and this doctrine have given a transcendent interest to the study of man; for they show that man may not only investigate the rest of the universe, but that he may, by the same means, investigate himself. Consciously or SCIENCE. 43 unconsciously, the terminology, the figures of speech and the modes of thought of sci- ence are being applied to all subjects and objects of human concern. They have penetrated the depths and the darkness even of the polite literature of our times. But while the ideal thus outlined appears to be the effective, or working, ideal at which we have arrived, it goes without say- ing that it is not the only ideal entertained by those whose opinions on academic ques- tions are worthy of regard. On the con- trary, many eminent minds deplore present tendencies and write and speak regretfully of the vanishing ideals of the past. Grave publicists, accomplished men of letters and subtle philosophers see little but danger in the educational readjustments of recent times. They deplore especially the decline in popularity of those ancient studies long called the humanities and the contempo- rary rise and increasing recognition of the newer studies. Culture, they seem to claim, comes inevitably through the pur- suit of the former, never through pursuit of the latter. They go so far in some cases as to decide at what point the study of a subject ceases to be liberal and begins to be illiberal, or professional. Give a student by the ancient formula, their facile editors say, that modicum of learning which would otherwise be dangerous, stamp him with the degree of A.B., and he becomes an aristo- erat. They take a gloomy view of the rest- less present and they are little hopeful of the future; for they hint darkly of ‘the bankruptey of science’ and of disasters im- pending if we do not return to ancient ideals. Argument concerning these matters is fruitless. Logie avails as little in an edu- eational campaign as political economy avails in a presidential campaign. Appeal must be had to our sense of humor and to the arbitrament of time. It may be ob- served, however, that these apostles of 44 SCIENCE. doubt and prophets of evil are slowly dis- appearing. They are more numerous out- side than inside academic walls, they are less strenuous in large than in small col- leges, and they are no longer dominant in the best universities. From a philosophic point of view they illustrate the action of a most interesting and usually beneficial sociological prine:ple. When consciously applied this principle may be called the law of rational conservatism. When uncon- sciously apphed it may be called, in anal- ogy with a great physical principle, the law of conservation of ignorance. It is so much more important for society to protect itself against the follies of the unwise than it is to profit by the improvements of the wise, that progress comes, generally, only painfully slowly. May we not entertain the hypothesis that the contemporary op- ponents of educational reforms have been animated towards them rather uncon- sciously than consciously? Having drunk deeply at certain fountains of learning, they appear to be sure that there are no others. They seem to have been, and to be, always reeeding. For more than a thousand years, in fact, the gaze of most scholars has been fixed so steadfastly on the glories of the past that it has been pos- sible to advance only by marching back- wards. Through the unconscious action of the law of the conservation of ignorance we are always in danger of disproportionate estimates of educational values and of er- roneous judgments in the larger affairs of life. We involuntarily revert to precedent, commending what is old, condemning what Thus, to give a concrete illustra- tion, fear and panic would be visible in our faces if we did not understand the mythical significance of the names Phobos and Dei- mos lately applied to the moons of the planet Mars; but very few of us would be- tray the slightest mental disquietude at our is new. [N.S. Vou. XXI. No. 524. profound lack of knowledge of the prop- erties of the atmosphere which is the me- dium of communication between you and me in this room. Thus, also, in spite of the obvious aphorism that all men are hu- man, they have been divided into human- ists and non-humanists, Matthew Arnold, for example, being one of the former, and the founder of our John Tyndall Fellow- ship being one of the latter. And stranger still, one might infer from the slowness of legal and constitutional reforms, and from many current arguments opposed thereto, that laws and constitutions are not made by men for men, but that, in some mys- terious way, men are merely experimental material for the training of crafty lawyers and sagacious politicians. But we have broken irrevocably with the past; not in the sense of disregarding the rich heritage of experience from our dis- tinguished predecessors, but in the sense that their customs and traditions no longer dominate us. We have corrected their observations for geocentric parallax; and we must now correct their observations for anthropocentrie parallax, just as our suc- cessors, if they prove progressive, will surely correct our blunders and avoid our errors. The need of corrections for an- thropocentric parallax in educational af- fairs is now widely recognized. It leads to the investigations of Mosely Commis- sions, to the conferences of the Association of American Universities, and to the broad- er conferences of world’s fair congresses. It is the chief source of the educational activities of our day. In these activities are to be seen the most hopeful signs of the times; for while agitation does not necessarily mean progress, serene content- ment is pretty certain to mean stagnation, if not regress. And the readjustment now going on in the academic world must continue. It isa part, simply, of the readjustment going on ee ee aL ae JANUARY 13, 1905.] in the intellectual world at large. We are, so to speak, in a state of unstable equilib- rium, wherein mental repose can be pur- chased only at the price of mental somno- lence. Great as have been the enlargement and the appreciation of educational and professional opportunities during the past three or four decades, we may confidently anticipate still wider enlargement and ap- preciation in the future. New divisions of knowledge may be expected to arise, and old divisions may be expected to undergo marked expansion, redistribution or emendation. The so-called humanities, especially, must be broadened, purified and elevated if possible to the intellectual level of the more highly developed sciences. It is clear, indeed, that in any revision of the humanities some matters may be redis- tributed, if not discarded, with advantage. The reckless amours and the clandestine peceadilloes of ancient and modern royalty, for example, should be transferred from the historian and the novelist to the anthro- pologist, the alienist and the pathologist. Such humanities, and many others of like kind, can hardly stand in comparison with the constancy of the stars and the beauties of harmonic analysis. All these matters of controversy, how- ever, belong rather to the lower than to the higher life of a university. How a student acquires elementary training is an academic question in the narrower sense of the word. The world cares little for edu- cational ways and means unless they can commend themselves by results. Attain- ments must be tested by achievements and proficiency must be proved by progress. To rise to this standard of excellence is the ideal of the higher life of a university. It is only by the pursuit of, and in the real- ization of, this ideal, that instructors and students may keep pace with and contribute adequately to the advancement of modern knowledge. Those who would separate SCIENCE. 45 theory from practice, those who would draw lines of invidious distinction between pure and applied science, along with those who would mistake a part of archeology for the whole of education, are all alike inimical to the trend of current progress. It is the highest function of a university to cherish this ideal and to promote espe- cially the arduous labors essential to fruit- ful original research. Those who ean add somewhat to the sum and substance of per- manent knowledge by the establishment of a physical, a social, an esthetic or an ethical principle, are the greatest benefac- tors of our race. Of the many who feel drawn to this high calling, however, few are destined for fame. Only those who prefer the turmoil of conflicting thoughts to the tranquility of inherited opinions, who can bear alike the remorseless dis- eipline of repeated failure and the pros- perity of partial success, may hope to attain renown. But, as those serve also who stand resolutely and toil patiently at their allotted tasks, so is there room in the grand aggregate of human achievement for the humblest as well as for the noblest of investigators. The ideals, then, of a modern university, like the ideals of the intellectual world at large, contemplate achievement and prog- ress in all grades of work from the lowest to the highest. They demand endless patience and unflagging industry from all who seek to rise above the dead level of mediocrity. The opportunities now af- forded for the pursuit of, for the acquire- ment of, and for the advancement of, learn- ing are greater than ever before. We are the heirs of the ages. But along with an increasing heritage there come increasing duties and inereasing responsibilities. It rests with us to show that we are worthy of this heritage and able to meet these duties and responsibilities. -This is the line of endeavor we resume to-day, and the spirit 46 SCIENCE. of the hour bids us look forward with cheer- ful optimism. R. S. Woopwarp. THE AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE. THE PRESENT STATE OF GEODESY.* THE problems of geodesy, like those of most sciences, enter upon new phases with the accumulation of facts bearimg upon them. The problem of determining the amount of the earth’s compression was added to that of determining the size of the supposed sphere as soon as Newton had demonstrated its oblateness. The contro- versy to which Newton’s theory gave rise was settled by the famous geodetic opera- tions of the eighteenth century which fur- nished the cardinal facts in regard to the earth’s figure and size. What may be regarded as the slow prog- ress of a more precise knowledge of the earth’s dimensions since that time must be attributed to the difficulties inherent in the problem. In the first place the dimensional meas- urements must necessarily be confined to the continental areas which occupy but three elevenths of the earth’s surface. The configuration and relationship of these areas make it impossible to girdle any sec- tion of the earth by direct measurement. Secondly, the admeasurement of these areas is far beyond the reach of individual enterprise and can only take place when the practical needs of governments suggest the utility of great mensurational surveys which at the same time and without great additional expense will furnish the data required for a more perfect knowledge of the spheroid. In making this statement it is not forgotten that individuals and covernments did undertake in all ages * Address of the vice-pres@lent and chairman of Section A—Mathematies and Astronomy, Amer- ican Association, Philadelphia, December, 1904. [N.S. Vou. XX]. No. 524. measurements for the purely scientific pur- pose of determining the size of the earth, for the desire for knowledge on this sub- ject may be reckoned coeval with intellee- tual development of man. Happily it may be said also that by their collective action the governments of the world have shown in recent times that it is considered a governmental function to sup- port and promote researches in this branch of science. I allude, of course, to the ex- istence of the International Geodetie Asso- ciation. It will not be out of place to say in this connection that the association exists by virtue of a formal convention between the participating governments, which are, at the present time, the United States, Japan and Mexico and all the European nations save Portugal, Roumania and the group south of the Danube No account of geodesy would be complete that failed to consider the aims and labors of this asso- ciation. Its history is part of the history of geodesy since 1861. At that time it ’ began its career as the Mittel Europaische Gradmesung. In a few years it expanded into an European association and in 1886 it became international. It is not generally known that it was this association which instigated the French government to invite the world to establish an international bureau of weights and measures at Paris. Without detracting in any way from the labors of Bessel, Clarke and others in intereomparing geodetic standards, the successful labors of the bureau which in consequence was estab- lished in Paris removed at least some of the difficulties that were encountered by the investigators in this branch of science, and by those engaged in the practical work of the measurement of the earth. The history of geodesy is full of in- stances of confusion and wasted energy due to the lack of a common standard, and the results of many are measures which would JANUARY 13, 1905.] - at least have great historic interest are utterly lost to us, because we can not make even a respectable guess at the units used. The adoption of an international unit of length and its necessary auxiliary, a com- mon thermometric scale, and the provision which the various governments made for the reference of their measuring apparatus to a common unit was a step of funda- mental importance. The association as such has no control over. the geodetic operations conducted by the different governments. Its function is to be the intermediary where cooperative action is needed, and to discover and point out along what lines the greatest need for information exists. In pursuance of these duties it has helped to perfect the European systems of trian- gulation by showing where missing links should be supphed, not only by measure- ment of angles and bases but also by addi- tional astronomical observations. It has made absolute gravity determinations with all the accuracy demanded by modern sci- ence and has caused suitable connection to be made by relative measures between wide- ly seattered pendulum base stations, and it has instituted unique relative gravity meas- ures, to which further reference will be made. It organized and maintains the sta- tions for observing the variation of lati- tude in regard to which it should be re- marked that it is the desire of the associa- tion to continue the observations beyond the year 1906, which marks the end of the ten-year period for which that service was tentatively organized. The association strongly desires not only to continue but to extend the service to the southern hemi- sphere and other latitudes than those now oceupied by the permanent stations, and to obtain the cooperation of suitably situated observatories in their endeavor to discover the cause of the phenomena. That the problem of determining the SCIENCE. 47 earth’s dimensions could not be solved by simply measuring two ares in suitable lo- ealities was brought home to geometers by the anomalous results obtained in the eight- eenth century. For instance, according to Lindenau the combination of the two Amer- ican ares, Mason and Dixon’s, measured in 1764, and that of Peru, measured a quarter of a century earlier, gave a value of one five-hundredths for the earth’s compression. The value derived from those measured in Great Britain alone was about nine times as great, or one fifty-fifth, while those made in France, considered by themselves, gave one one-hundred-and-fiftieth. It is not now important to inquire whether these differences are not in part due to the erudi- ties of the methods of measurement em- ployed. They were sufficiently real to throw doubt on the belief that the earth could be represented by a regular mathe- matical figure. Finally, the existence of local deflections of the vertical as affecting the amplitude of ares was recognized, but not taken into account save, perhaps, by arbitrary exclusion of stations showing ex- ceptionally large deflections. The method of finding an osculating spheroid from are measures remained in its essence that of taking averages of meas- urements reduced to the geoidal surface. The differences between the observed direc- tions of the vertical and those computed on an assumed spheroid of reference were treated as if they were accidental errors of observation. At the present time it is the aim of geodesists to assign to the deflections their proper place in the computations and to interpret them by discovering through them and through gravity measurements the manner of the distribution of masses in the interior of the earth. Thus geodesy is trenching on the domain of geophysics and geology. In India, in Europe and in the United States the study of these deflections is re- 48 SCIENCE. celving special attention. In the last- named countries the junction and correla- tion of the triangulation, which was for- merly disjointed, makes it possible to take up the study. Similarly in this country the completion of the transcontinental are and its connection with the lake survey tri- angulation furnished the opportunity and oceasion for adopting a standard datum of geographical coordinates for the whole country. This in turn furnished the de- flections of the vertical referred to a com- mon origin of coordinates on the same spheroid and made it possible to begin the study of the form of the geoid in this coun- try over a very extended area. The investigation has so far been extend- ed over the eastern part of the United States. Here as elsewhere it was found that the curves of elevation of the geoid above the spheroid reflect perceptibly the visible topographic features. A preliminary statement of the scope of these investigations was recently given be- fore the International Geographic Congress by Mr. Hayford, the chief of the computing division of the Coast and Geodetic Survey. From it I quote as follows: The conclusion that for the eastern half of the United States and the adjacent portion of the Atlantic the theory of isostasy is true to a con- siderable extent is reasonably safe. The conclu- sion that the depth within which the isostatic compensation takes place is 205 miles is one which may be modified considerably as the inves- tigation proceeds. The investigation thus far leaves the signs of the corrections to the constants of the Clarke spheroid of 1866 uncertain. Mr. Hayford will give before this meet- ing an account of the method devised by him of computing the topographic correc- tion. The task of computing this correc- tion to a distance of 4,000 kilometers for each of say 500 stations has been rendered possible by this method, which is, therefore, referred to by me as a distinet advance in geodesy. [N.S. Vou. XXI. No. 524. It is hoped that the completion of the study of the data now available in regard to the deflections will serve as a guide to the most effective use in the future of the pendulum, and it is on this account largely that pendulum observations have been for the present deferred by the coast survey. They are, however, being actively made by other nations. A new impetus was given to relative gravity observations by the adoption of short and light pendulums in place of the heavy seconds’ pendulum. Aside from their portability, their lightness insures greater invariability for the knife edges, simplifies the task of securing uniformity of temperature and pressure in the metal cases in which they are swung, and the ease with which a low and constant pressure can be maintained in the case insures the continuance of the swing through so long a period that the errors of the chronometer or, other timepiece are eliminated. Thanks to the efforts of the International Geodetic Association, the widely scattered base sta- tions have been connected with the central station of the association at Potsdam, where a long series of absolute gravity determina- tions were brought to a successful conelu- sion two years ago. The association has available now the data from nearly 1,800 stations seattered over various parts of the globe. A most interesting and valuable extension of relative gravity measures to the surface of the ocean was made two years ago. The principle upon which the new method depends is that if the atmos- pherie pressure is determined at the same time and place by means of a mercurial barometer on the one hand and by the temperature of the boiling point of water on the other, the observed height of the ba- rometer will be affected by gravity at the place, while the result by the hypsometer will be independent of it. According to Dr. Hecker, who carried out the laboratory JANUARY 13, 1905.] experiments as well as the actual test at sea, the suggestion that the two instruments might be used for the determination of differences of gravity was first published in 1894 by Dr. Guillaume, of the Interna- tional Bureau of Weights and Measures at Paris. Dr. Mohn, of Christiania, success- fully apphed the method by actual tests in various places in Norway for the purpose of determining the gravity reduction of the barometer for meteorological purposes. Doctor Hecker installed his apparatus on a steamship and sailed from Hamburg to Rio Janeiro via Lisbon, Portugal, and Bahia, Brazil, and returned on another steamer to Lisbon, making observations both ways. The results of his observations have been published and show: 1. That the intensity of gravity on the Atlantic Ocean between Lisbon and Bahia is nearly normal, and agrees with the theo- retical values computed by means of the general formula published by Helmert in 1901. 2. That the difference of gravity at sea in shallow water and in deep water corre- sponds approximately to the difference of gravity between coast stations and inland stations. These results were submitted to the Geo- detic Association at the last meeting. Means were provided for another expedi- tion and last March Dr. Hecker began his journey, crossing the Indian Ocean and the Pacific by way of Melbourne and Sydney to San Francisco. Thence he recrossed to Japan and China, and we may look for- ward to an early statement of the results, which are being awaited with deep interest. As in the case of the pendulum already referred to, there has been in the last dec- ade a decided improvement and simplifica- tion in instrumental means and methods of work. It is only necessary to cite the in- troduction of tapes and wires for primary base measurement, the introduction of the SCIENCE. 49 transit micrometer for the elimination of personal equation in time determinations, and of the leveling instrument, devised in the coast survey, which is making its way into more general use. With the use of the latter there has just been satisfactorily completed the first precise line connecting the Atlantic, Gulf and Pacific mean sea levels in the coasts of the United States. In all countries the determination of the mean sea level and the establishment of so- called bench marks in the interior are being actively prosecuted as they furnish part of the required geodetic data. In beginning I referred to the measure- ment of continental areas. Let us see what has been accomplished as to the extent of areal measurement since Snellius intro- duced triangulation into geodesy 289 years ago. In our own hemisphere, so far as I am able to learn, about the three-hundredth part of one per cent. of the area of South America has been covered ; of Mexico about one per cent.; of the United States about five per cent. Geodetically the British pos- sessions in the western hemisphere are bar- ren. We may say that less than three per cent. of the western hemisphere has been triangulated. In the eastern hemisphere we find that about forty per cent. of Europe has been covered, but if we leave out Russia the per- centage rises to eighty per cent. for the rest of Europe. The triangulation of Asia is furnished by India and Japan, Java and Sumatra and amounts to about four per cent. Australia shows about two per cent., Africa about two and six tenths per cent., making a total for the eastern hemisphere of about seven per cent. If we exclude the north and south polar regions a little over six per cent. of the available land area has been triangulated, or about one and one half per cent. of the total surface of the globe. These figures 50 SCIENCE. are accurate enough for the purpose for which they were compiled, that is, to show the relatively small area covered. There is, however, another side to the picture, the hopeful one. In South America the are of Peru is being remeasured and extended by the French government. As the work is being carried out with the advice of the most distinguished mathematicians of France, the results will be, in their impor- tance, out of all proportion to the extent and area involved. Mexico has made a brave beginning and is working towards a connection with an extension of the ninety-eighth meridian measurement, of which the United States has completed about three quarters of the amplitude lying in her own domains. Work on the Pacific coast are has been resumed and it has nearly been completed from San Diego to the Columbia River. Two years ago the Russians and Swedes jointly completed an are in Spitzbergen between latitudes 76° and 81°. The Euro- pean ares are being extended eastward by Russia, and one must look forward to the ultimate connection between the Russian trianeulation at Astrakhan or Orsk and the Indian triangulation, however improb- able it may seem if looked at from a po- litical view point. In Africa the work of extending the South African ares northward from the Cape towards Alexandria is well under way, and no doubt need be entertained that the British and Germans will earry it through. A general review of this part of the field of geodesy shows that while some ereat geodetic measurements have been completed or are approaching completion, new ones are being undertaken under the fostering care of different governments. Reasoning from the experience of the past, we may econelude that the solution of one problem in geodesy will disclose the [N.S. Vou. XXI. No. 524. existence of another, and from the trend of the investigations of the present that other than purely mathematical and astro- nomical sciences will be advanced by the search for their solution. That the progress of the branches of science to which this section of our asso- ciation devotes itself was greatly affected by the problems of geodesy was pointed out by Humboldt in language which may fittingly conclude these remarks: Except the investigations concerning the par- allax of the fixed stars, which led to the discovery of aberration and nutation, the history of science presents no problem in which the object obtained— the knowledge of the mean compression of the earth and the certainty that its figure is not a regular one—is so far surpassed in importance by the incidental gain which, in the course of long and arduous pursuit, has accrued in the gen- eral cultivation and advancement of mathematical and astronomical knowledge. O. H. TirtMann. U. S. Coast AND GEODETIC SURVEY. DEVELOPMENTS CHEMISTRY .* Ir has been the custom of the retiring officers to discuss the development of some portion of that field of chemistry in which they were most interested. Since the president of the American Chemical So- ciety will speak on physical chemistry to- morrow night, it has seemed to me that I might break with tradition and discuss the future of physical chemistry rather than its present or its past. We have reached a eritical stage in the development of the electrolytic dissociation theory. The work of Kahlenberg has shown that there are a number of facts which we did not anticipate and which we ean not explain satisfactorily at the pres- ent time. The recent experiments of Noyes show that the dilution law does not hold for any strong electrolyte and that the FUTURE IN PHYSICAL * Address of the vice-president and chairman of Section C—Chemistry, Philadelphia, 1904. JANUARY 13, 1905.] sanie empirical equation describes the be- havior of binary and of ternary electro- lytes. This last fact appears to be fatal to all explanations based on the assumption that electrostatic effects are the disturbing factors. While the mutual attraction or repulsion of two ions or of three ions may easily change the dissociation formula for a binary or a ternary electrolyfe, it is very improbable that the changes will be such as to make two radically different formulas identical. Of course, the hypothesis of hydrated ions gives us some leeway but the outlook is not what it was five years ago. It is too soon yet to say whether we are merely to remodel the electrolytic dis- sociation theory or whether we are to re- place it by something else. My own opin- ion is that reform is what is needed and not revolution. It is evident, however, that we have gone ahead too fast and that we must test more thoroughly the premises on which our conclusions are based. We know of one error. The proportionality between molecular weight and osmotie pressure holds only for the cases in which the heat of dilution is zero. This is stated clearly in van’t Hoff’s original deduction of the van’t Hoff-Raoult formula n/N —log p/p,, but has been pretty generally over- looked. Since the heat of dilution is rarely zero in any actual case, our deductions as to the molecular weights of solutes are always somewhat in error. In the ease of the metals of the alkalies and the alkaline earths dissolved in mereury, the lowering of the vapor-pressure due to the heat of dilution is practically equal to that due to the molecular weight, and we therefore have the surprising result that the appar- ent molecular weight is only about one haif the atomie weight. One of the first things we have to do is to eliminate this source of error in all eases. Another distressing feature in the quan- titative physical chemistry of to-day is that SCIENCE. 51 the field which. it covers is daily growing less. A tenth-normal solution is now con- sidered a concentrated one, and some people are so extreme as to maintain that we can not expect agreement between theory and experiment for anything except infinitely dilute solutions. To my mind a theory which holds only for infinite dilution is necessarily wrong. Here again one prob- able source of error is easy to find. The van’t Hoff-Raoult formula is deduced on the expleit assumption that there is no specifie attraction between solvent and solute. If this assumption is wrong, it is reasonable to suppose that the error thus introduced would become less as the con- centration approaches zero. Under these circumstances the van’t Hoff-Raoult for- mula might represent the facts at infinite dilution without being a true formulation. This is the case with another well-known and important formula. The Helmholtz and the Nernst equations, for the electro- motive foree of concentration cells are identical for infinitely dilute solutions and for these only. The Nernst equation ignores the coneentration of the undis- sociated salt, while the Helmholtz formula- tion does not. The two equations become identical at the moment when the concen- tration of the undissociated salt and the disturbing factor due to it become zero, that is, at infinite dilution. Since the Helmholtz formula applies to all concen- trations, the Nernst formula is necessarily only approximately accurate. This has been recognized explicitly by Planck, though the point is often overlooked. It is quite conceivable that the shortcomings of the van’t Hoff-Raoult formula may be due in part to theoretical inaccuracies and that we have laid too much stress on ‘vari- ations from the gas laws.’ If we introduce the conception of a specifie affinity between solvent and solute in certain eases, notably those in which the 52 SCIENCE. heat of dilution is marked, we combine all of what has stood the test with what is good in Kahlenberg’s conceptions and I believe that we are nearly ready to take a long step forward. One point must be kept in mind, however. Raoult’s experiments preceded his formula. Before we can hope to work out a satisfactory theory of concentrated solutions, we must have ac- curate measurements on concentrated solu- tions and at present we have practically none. We need experiments at constant temperature on the compositions of co- existent liquid and vapor phases for binary systems with one volatile component and with two volatile components. These measurements are not easy to make and that is one reason why they have not been made. We have measured boiling-points and freezing-points because they are easy to measure; but for a theory of concen- trated solutions the value of such measure- ments is very small. This is because we are then measuring the combined effect of the change of the pressure with con- centration and with temperature, whereas we ought to study the two separately. Fur- ther, if we are to express our results in volume concentrations we must give the volume concentrations of both components. It would be absurd to pass from dilute to syrupy solutions of sugar, for instance, and to treat the concentration of the water as constant. Personally, I believe that the theory of concentrated solutions is rela- tively simple and that the difficulties have been chiefly of our own making. My own experience with ternary mixtures confirms me in this view. In developing a theory of concentrated solutions we must also keep in mind the actual properties of the com- ponents, a thing which we have not done in the past. Thus the dissociation equa- tion for liquid chloral hydrate can not be the same as that for liquid chloral aleohol- ate because chloral is miscible in all pro- [N.S. Vou. XXI. No. 524. portions with alcohol and forms two liquid layers with water. This is a perfectly obvious fact, yet no reference to it is to be found in any text-book on physical chemistry. In the last ten years the work of Rooze- boom and others has brought the phase rule to the front as a basis of classification and as an instrument of research. The im- portance of the phase rule is going to in- crease very rapidly in the next decade. The study of alloys has really only just begun. Our knowledge of the carbon steels is still very incomplete and unsatis- factory. In fact, we know the constitution only of a very limited number of binary alloys. Nothing systematic is yet known about the chemical properties of alloys or about the conditions for electrolytic precipitation. The variation of the engi- neering properties, such as tensile strength, torsional resistance, ductility, ete., with varying concentration and varying heat treatment is a subject which can only be worked out satisfactorily with the phase rule as a guide. On the basis of what has been done it appears quite safe to predict that we do not yet know one half the pos- sibilities of our structural metals. Quite recently the constitution of Port- land cement has been established and we owe this result to an application of the phase rule. It will not be long now before we get much clearer ideas on the causes of the strength of cements and of the plas- ticity of the clays. The time will soon come in our engineering schools when the subject known as ‘Materials of Engineer- ing’ will have to be taught by the chemist rather than by the engineer. The applications of the phase rule to petrography will be numerous and will come soon. It is evident that no rational classification of minerals ean be possible until the constitution of the minerals has been determined. The situation in regard JANUARY 13, 190v.] to petrography is much the same to-day as it was in regard to alloys a few years ago and we may reasonably expect as satisfac- tory results from rocks as from metals. More and more people are experimenting with fused salts and the new geophysical laboratory at Washington is planning to study igneous rocks in the same thorough way that van’t Hoff studied the Stassfurt deposits. The problem is a difficult one experimentally, but it can and will be solved. The classification of electrochemistry under the phase rule is a problem of the immediate future. Some work has been done already, but it is confined to the dis- cussion of the electromotive forces of cer- tain reversible cells. What I mean is some- thing vastly wider than this, the applica- tion of the phase rule to all electrolytic and electrothermal processes. Since electro- chemistry is essentially chemistry, a classi- fication which is of fundamental impor- tance in chemistry must be equally neces- sary in electrochemistry. The extension of the phase rule to or- ganic chemistry is an achievement about which we like to dream, but the realization of it seems far off. To treat a large por- tion of organic chemistry as a system made up of carbon, hydrogen and oxygen wiil some day be possible; but at present we are balked by so-called ‘passive resistances to change.’ Theoretically methyl ether, (CH,),0, and ethyl alcohol, C,H,OH, are two modifications of the substance C,H,O and they should be mutually convertible. Practically they are not. Only one of the three dibrombenzenes can theoretically be the stable form. Actually, we can not con- vert any one of them directly into either of the other two. In spite of all this there is really quite a mass of material waiting to be worked up. Reversible equilibrium between hydrogen and oxygen can be realized at all tempera- SCIENCE. 53 tures. Reversible equilibrium between car- bon, carbon monoxide and carbon dioxide is possible above 200°, while reversible equilibrium between carbon, methane, acetylene, ethane and hydrogen can be ob- served above 1200° without catalytic agents. Carbon monoxide and water re- act at 480° in presence of copper. Methane can be made from carbon monoxide and hydrogen at 250° in presence of nickel, while methyl alcohol can be changed to earbon monoxide and hydrogen by zine dust. The decomposition of alcohols into aldehydes, or ketones, and hydrogen is re- versible. Aldehydes can be changed into carbon monoxide and paraffines, though the reverse reaction has not been accomplished satisfactorily. Methylal and acetal are formed by a reversible reaction, while the ester formation has been studied for years. Formic acid decomposes into carbon mon- oxide and water when heated by itself, and into carbon dioxide and hydrogen when heated in presence of rhodium. Starting from carbon monoxide and caustic soda we can make sodium formate, carbonate and oxalate. As yet only a few of these reactions have been studied with care and we do not know how many of them are reversible or what are the temperature limits. We do not even know whether colloidal metals act more effectively than the pulverulent metals, although it is very probable that they do. While we ean not yet tell how far we may be able to go, it is clear that the attempt to apply the phase rule to organic chemistry opens up a most inter- esting field of research both as regards or- ganic chemistry and as regards the theory of catalytic agents. The usefulness of the phase rule in study- ing basic and double salts is being realized more and more by our friends the inor- ganic chemists. The recent work on the changing solubility of the hydroxides of 54 SCIENCE. many of the metals ealls attention to a possibility of error which must not be over- looked. In all eases of hydrolysis there is always a possibility that equilibrium may not be reached in weeks or months. The only safe way is to reach the equilibrium from both sides. In this way and only in this way do we get any clue to the magni- tude of the error involved and it is only after we have done this that we are justified in assuming that a reaction is irreversible. The application of the phase rule to the fractional erystallization of rare earths would certainly lead to marked improve- ments. There are few people who could separate potassium and sodium chlorides by fractional crystallization, getting out all of each salt entirely pure. Even fewer would be able to separate potassium sul- phate and copper sulphate. In spite of this we start in cheerfully on the fractional erystallization of an unknown number of elements having unknown properties. The result of all this is that we reach a point where further separation is impossible and yet we do not know why. - This state of things is really the fault of the physical chemist and not of the inorganic chemist. It is not to be expected that the inorganic chemist can start in off-hand and apply the phase rule to the study of basic and double salts or of rare earths. Before this can be done the physical chemist must work out the methods and must be prepared to sive explicit working directions, possibly in the form of recipes. It must also be clear to you that a study of the conditions of existence of com- pounds, atomic and molecular, is a pre- requisite to any theory of valency, In the past, reactions in organic chem- istry have been studied by physical chem- ists chiefly as examples of reaction velocity. There are two other fields which will re- ceive more attention in the near future, namely, yields and irreversible reactions. [N.S. Von. XXI. No. 524. The question of yields is in a very bad way. In Lassar-Cohn’s admirable book on laboratory methods in organic chemistry there is an enormous amount of valuable material; but there is really very little in the way of theory. Although we know that a reversible reaction will run to an end if the concentration of one of the re- acting substances be kept practicaily zero, surprisingly little use has been made of this principle. We know that certain re- actions take place better in dilute solutions or at low temperatures or in certain sol- vents, but in most cases we can not tell why. In the pyridine method for introducing acetyl or benzoyl groups the pyridine is said to be effective because it is a weak base; but it is much more probable that it acts as a catalytic agent. We do not know how far the dehydrating action of certain reagents is simply a question of vapor-pressure or how far there is a specifie effect due to the particular reagent. The action of sulphurie acid in the formation of ether is something more than a dehydrat- ing effect, and the same is true of the effect of zine chloride in the synthesis of ethyl ehJoride. A single instance will be sufficient to show the state of confusion that exists. Anschiitz’s method of preparing certain esters was to saturate the solution with hydrochlorie acid gas and to allow the solu- tion to stand overnight. Fischer improved on this by adding less acid and by raising the temperature. He boiled for two hours and found that the hydrochlorie acid con- centration could be reduced to three per cent. without affecting the yield. There the matter is left and we are led to look upon a three per cent. concentration as having special merits, whereas this is un- doubtedly merely a result of boiling for the arbitrary period of two hours. If Fischer had boiled for one hour only he would have had to use a stronger acid to JANUARY 13, 1905.] have reached equilibrium in the allotted time. If he had boiled three hours, the lowest permissible concentration of hydro- ehlorie acid would undoubtedly have been less than three per cent. Anschiitz, on the other hand, worked at ordinary tempera- ture and his solutions consequently needed more acid and more time to approximate to equilibrium. All of this is really first principles and it is only one ease out of many. If any one will try to classify and explain the results given in Lassar-Cohn’s book, he will find himself provided with enough interesting research to last him the rest of his natural life. The second field for research to which I have alluded is that of irreversible reac- tions. In inorganic chemistry there are as yet no well-authenticated cases where a re- action starts and then stops short of equi- librium. The results of Pélabon on hy- drogen and selenium and of Hélier on hy- drogen and oxygen have heen disputed by Bodenstein and must for the present be considered as wrong. In organic chemistry we appear to have many such reactions, typical instances being the formation of nitro-benzene and the decomposition of al- dehyde into methane and carbon monoxide. While it is possible that these and other reactions run to an end in infinite time, we have not infinite time at our disposal, and it may, therefore, prove profitable to find out whether and how the apparent end- point varies with varying initial conditions. This work is desirable now and will become necessary if we should ever revise our opin- ions as to the theoretical possibility of an irreversible equilibrium. By definition we ean not determine the existence of an ir- reversible equilibrium by approaching the end-point from the two sides. It seems to me probable, however, that we ean draw conclusions from the reaction velocity. If we are dealing with a case of a theoretic- ally reversible reaction running practically SCIENCE. 55 to an end, I can see no reason why the con- centration of the decomposition products should have any effect on the reaction ve- locity, so long as we confine ourselves to gaseous systems. If, however, we are deal- ing with a theoretically irreversible reac- tion which does not run to an end, the reae- tion velocity would vary with the concen- tration of the decomposition products. It should be noticed that it will not do to reason from the behavior of a system in presence of a catalytic agent to that of a system without a catalytic agent, since the catalytic agent may displace the equilib- rium. Thus ethyl aleohol is decomposed by heated copper into aldehyde and hydro- gen, while heated alumina changes it chiefly into ethylene and water. It was the study of organic solutes in organie solvents which led Raoult to the formulation of his law. It seems probable that a study of organic reactions may lead to an entirely new class of equilibria. If this happens it will throw much light on the preceding problem be- cause it is very difficult to explain some of the peculiarities in regard to yields in or- ganic chemistry so long as we are obliged to postulate reversible reactions only. The theorem of Le Chatelier has been applied chiefly to heat and work effects, but this is by no means the extent of its usefulness. Wherever we get a reversible displacement of equilibrium by lght, it must be possible to make use of this the- orem. The change of color of the silver photochlorides is in accordance with the theorem; but there seems to be no reverse change in the dark. The simplest case with which to. begin would appear to be the formation of ozone. There seems to be a contradiction here. Ozone is known to ab- sorb ultra-violet light and yet it is believed to be formed by the action of ultra-violet light. Whether we are dealing with the same sets of rays in the two eases is a point that has not been settled. In fact. we do 56 SCIENCE. not know definitely whether ozone is formed by the action of ultra-violet light in the ab- sence of electrical waves, though this is a matter easily settled by experiment. We know that ozone gives out light on decom- posing, but we do not know anything about the spectrum of this light. It is quite probable also that we must formulate the theorem of Le Chatelier more exactly than we have hitherto done before we can apply it suecessfully to the phenomena of light. An instance based on electrical phenomena will show what I mean. If a voltaic cell be short-circuited the chemical change will be such as to decrease the electromotive force of the cell. If we do not keep the cell at constant temperature the Joule heat will cause the temperature to rise and this may either raise or lower the electromotive force of the cell. We are then really con- sidering two phenomena, the electrical and the heat effects. One may mask the other completely. In one case, at any rate, we know that we can apply the theorem of Le Chatelier to‘light phenomena. Suppose we have a gas enclosed in a transparent adiabatic vessel and concentrate upon it light of a wave-length that is absorbed by the gas. The temperature of the gas will rise and equilibrium will be reached when the gas has changed so that it no longer absorbs light of that particular wave-length or when the gas emits light of the same wave- length and intensity as that which is acting upon it. This emission by a gas at some temperature of the light which it absorbs at the same temperature is Kirchhoff’s law, which thus appears as a special case of what the chemists call the theorem of Le Chatelier. To be frank, I do not now see how we are to apply this theorem to the phenomenon of phosphorescence, and yet we are dealing with an absorption and an emission of light. I venture to suggest that it is to the application of the theorem [N.S. Vou. XXI. No. 524. of Le Chatelier that we must look for a rational treatment of phosphorescence, fluorescence, chemiluminescence, ete., rath- er than to a theory of vibrating molecules. It will be time enough to discuss the appli- cation to radiations when we have solved the simpler problem of the theory of cold light. A discussion of equilibrium relations would not be complete without some refer- ence to the future of thermodynamics in chemistry. There are two radically dis- tinct ways of considering the relation of thermodynamics to chemistry. One is to look upon thermodynamics as a mathemat- ical shorthand. The aim of thermody- namics is then to present a consistent and formal treatment of the known energy re- lations. In this case thermodynamics deals with the past and not with the future; with the classification of knowledge and not with the discovery of new laws. This is the point of view of most mathematical chem- ists and it is because of this that we do not turn to the mathematical chemist for new ideas. There is another way of consider- ing thermodynamics, namely, as an instru- ment of research. It is not too much to say that the mathematical chemist can work out in a few hours or days results which would take his less fortunate col- league months or even years to obtain. At present the race is to the tortoise and not to the hare; but I can not believe that this will always be so. Other things being equal, the man who can handle his thermo- dynamics will beat the man who can not; but in order to have that take place thermo- dynamics must be considered as an instru- ment of research and not as a branch of metaphysics. We must confess that the mathematical chemistry of the past decade has not done what it should have done and that there is no immediate prospect of any improvement. In the meantime we do not despair. There are great possibilities in JANUARY 13, 1905.] the application of mathematics to chem- istry and some day they will be developed. So far we have considered problems in- volving equilibrium only. When we begin to study the conditions which make a reac- tion possible and which govern its rate, we are brought face to face with our need for a satisfactory theory of catalytic agents. We know experimentally the catalytic ac- tion of many substances on many reactions, but we have not even the first suggestion of an adequate theory. This is a subject of more vital importance than may appear at first sight. I wish to call your attention to two very important matters which de- pend directly upon catalytic agents. The first is the chemistry of plants. We can make in the laboratory many of the sub- stances which the plant makes. Some of them, such as alizarine and indigo, we can make more cheaply than the plant can, and of a higher degree of purity. As yet we can not make any of them in the way the plant does, and this gap in our knowledge will have to be filled by the physical chem- ist, as the problem apparently does not appeal to the organic chemist. The plant does not use reverse coolers or sealed tubes; it does not boil with sulphuric acid or fuse with caustic potash; it has not metallic sodium and chlorine gas as reagents. The reagents on which the plant can draw are air, water and a few mineral salts. As catalytic agents it has heat, light, difference of electrical potential, enzymes—and itself, namely, living protoplasm. From the work of Bredig and others we know that colloidal metals, the so-called inorganic ferments, ean be substituted for enzymes in some eases. As we do not yet know our limita- tions, it is quite possible that we can substi- tute inorganic catalytic agents for the en- zymes in all cases. If that proves to be true we can then duplicate everything ex- cept the plant itself, and we shall be ready to determine how closely we can duplicate SCIENCE. 57 the reactions of the plant. The experi- ments of Sabatier and Senderens in France are distinctly encouraging, even though they do not carry us very far. By means of nickel powder it is possible to reduce acetaldehyde to aleohol with hydrogen at 30°. This is the best result that has been obtained and it indicates the possibilities. When we get a satisfactory theory of ecata- lytic agents we shall undoubtedly be able to duplicate many of the plant syntheses and our failures will be interesting as bringing us nearer to the most difficult problem of all—that of life. Pending the development of a satisfactory theory of eatalytie agents, there is much to be done in the way of experimenting. In view of the fact that mixtures of two catalytic agents often act more intensely than would be expected from the behavior of each taken singly, it would appear advisable to determine the combined effects of inorganic ferments and ultra-violet light. The second problem, which would be easier of attack if we had a satisfactory theory of catalytic agents, is that of the transmutation of the elements. This is now admitted to be distinctly a scientific problem, though not one in which we have made much progress. It is usually as- sumed that it is a very difficult problem. While this may be true, we have not yet reached the point where we are justified in being certain of it. No one has ever at- tacked the problem systematically and all we can say is that the rate of change has been small under any conditions that we have yet realized. That is not surprising. We should naturally expect a low reaction velocity. The rate of change of radium is so slight that it could not be detected by any ordinary methods. The fact that we have never observed any transmutation of the elements does not prove that none has taken place. We had been making dia- monds artificially for years, even for cen- 58 SCIENCE. turies, but nobody thought of looking for them in east iron until after Moissan made his experiments a few years ago. If we aecept Lockyer’s conclusions as to the state of things in the sun, we could undoubtedly break up many of the ele- ments if we could hold them long enough at 6000° C. One difficulty is to get the temperature, and of course we must be cautious about conclusions based on simpli- fied spectra. Many people have thought that radium was to be the catalytic agent which was to change all the elements; but the recent work of Rutherford seems to put an end to this idea. If radio-active lead, tellurium and bismuth are merely these elements plus the radium emanation or one of its decomposition products, there is very little evidence to show that any of our well-established elements are undergo- ing any change from contact with radio- active substances. Another possibility which has been sug- gested is that we could change our elements if we could pump energy into them and change their energy content. This would have to be done electrically if at all. I have been told that Stas was busy during the last years of his life trying to change sodium into something else by an electrical process. The difficulty is to pump energy into the element. Passing a heavy cur- rent through a metal produces no effect that we know of other than to raise the temperature. Taking the element in the state of gas enables us to employ a higher potential difference, but here the effective- ness of the method is limited by the appear- ance of the are. The first stage in the problem would, therefore, be the attain- ment of the highest possible potential dif- ference without causing arcing. In view of the remarkable insulating action of gases under high pressure, it seems as though the silent discharge through compressed gases were the thing to try. The difficul- [N.S. Von. XXI. No. 524. ties people had in proving the dissociation of water at high temperatures makes us realize the possibility that we might decom- pose our elements and never know it, owing to the recombination taking place at once. If we are to simplify our elements by pumping energy into them, it appears that we should work with gases under high pres- sure, with the highest potential difference compatible with the absence of sparking, and with some application of the principle of the hot-cold tube. While the methods of extremely high temperature and of high electrical stress have much to commend them on paper, they are liable to fail owing to the diffi- culty of attaining the proper temperature or the proper electrical stress. The ideal method would be to find a catalytic agent which would accelerate the rate of change and which would eliminate what we should then call the instable elements. Since there is no immediate prospect of our being able to predict the suitable catalytic agent and the conditions under which it is to be used, we must ask ourselves what is the scientific method of attacking the problem of the transmutation of the elements. The answer is a simple one. We must start with the simplest case, study that thoroughly, and work up gradually to the more difficult tasks. We should begin with the cases in which we know a change is possible and should study the allotropic forms of the elements. At present our knowledge of these is disgracefully incom- plete. We know a little about sulphur, phosphorus, carbon, selenium and tin; but even for these few elements our knowledge is incomplete and it is especially unsatis- factory in matters bearing on the rate of change. In most eases the change from one allotropic form to the more stable one is fairly slow. It is not even easy to get large amounts of gray tin. On the other hand, Saunders discovered, quite by ac- JANUARY 13, 1905.] cident, that there were a number of sub- stances, notably quinoline, which convert amorphous selenium into the more stable, black, metallic modification. It is probable that similar results could be obtained with other elements. Kastle has shown that the rate of change of yellow mercuric iodide into the red form varies enormously with the nature of the solvent. The first thing that we need is a systematic study of the allotropic forms of the elements, con- sidering reaction velocity as well as equi- librium. We next take up cases where the change from one form to another can be made increasingly difficult. The three disubstituted benzene compounds, as I have already said, are to be considered as dif- ferent modifications, only one of which can be stable as solid phase at any given tem- perature and under atmospheric pressure. According to the text-books o-phenol sul- phonie acid changes readily into p-phenol sulphonic acid on heating. When bromine acts on phenol in the cold, p-bromphenol is formed, while o-bromphenol is formed when the reaction takes place at 180°. I have not been able to find any record of the p-brom compound changing into the o-brom compound on heating; but the ex- periment is worth trying. When we come to the three dibrombenzenes, we have a case where we know that the three forms are identical in composition and where there is certainly some sort of an equi- librium at the time of formation because the relative amounts of the modifications ean be changed by varying the conditions of preparation. In spite of all this we know no way of converting two of these compounds directly into the third. We could undoubtedly do it if we could raise the temperature high enough, just as we could also convert the elements. It is as yet impossible to attain the temperature at which the elements change rapidly, while secondary reactions interfere in the case SCIENCE. 59 of the organic compounds. So long as we can not change the two less stable forms of any disubstituted benzene compound into the most stable form, there is no reason why we should expect to succeed in what may, perhaps, be the impossible task of simplifying the elements. Summing up, the future developments in physical chemistry will comprise a theory of concentrated solutions, further applications of the phase rule and of the theorem of Le Chatelier, a systematic study of organic chemistry, and a theory of catalysis. Wiper D. BAncrort. REPORTS OF COMMITTEES. Tue following reports of committees were presented to the council. They were accepted and ordered printed: On the International Congress of Americanists. “The International Congress of Americanists held its fourteenth biennial meeting in Stuttgart. Germany, August 18-23, 1904. On June 1, 1904, I received a communication from you announcing my appointment as the representative of the American Association for the Advancement of Science at this meeting. The designation was gladly accepted, as it had already been arranged that I should attend the congress on behalf of the Smithsonian Institution. I now have the honor to report that the meet- ing was in every way a most gratifying success and that the representation of the American As- sociation was duly recognized and published in the official bulletins of the congress. The attend- ance was largely German, but representatives from a dozen other countries were present and took an active part in the proceedings. The papers presented related almost exclusively to American history and anthropology and especially to South American subjects. The Germans as well as the French have given very great atten- tion to investigations on that continent. The next meeting of the congress is to be held at Quebec in August, 1906. Very respectfully, W. H. Homes. On Anthropometry. The committee beg to report that individually and as a committee they have been carrying on 60 SCIENCE. anthropometric work during the past year. It was not feasible to arrange an anthropometric laboratory last year at St. Louis, but this year excellent arrangements have been made in con- nection with the psychological laboratory of the University of Pennsylvania. Measurements of the members of the association are being made by Messrs. V. A. C. Henmon, F. Bruner and G. C. Fracker, with the cooperation of Professor Thorn- dike, Dr. Woodworth and members of the com- mittee. The chairman of the committee is ma- king an extended study of American men of science; two papers have been published on the subject and there is now in press a ‘ Biographical Directory of American Men of Science,’ containing much material that can be used. We may call special attention to the Anthropometric and Psychometric Laboratory of the Louisiana Pur- chase Exposition, arranged by Dr. McGee, head of the Department of Anthropology. The labo- ratory, under the direction of Dr. Woodworth, as- sisted by Mr. Bruner, made measurements of about 1,000 representatives of different races, especial attention being paid to the native races of the Philippine Islands. We ask that the committee be continued and that an appropriation of fifty dollars be made for the expenses of an anthropometric laboratory at the next meeting of the association. J. MCKEEN CATTELL, Chairman. On the Atomic Weight of Thorium. The work on the ‘Complexity of Thorium’ by Chas. Baskerville and R. O. E. Davis, referred to in our Jast report, has been repeated, verified and extended by Fritz Zerban. The investigation was prosecuted partly in the laboratory of the Uni- versity of North Carolina and is continuing in the College of the City of New York. Larger amounts of the pure thorium compounds have been frac- tioned. busied thorium the contaminating constituents prelimi- nary to a determination of its physical constants. Coincident with this work they are studying the properties of the novel impurities, which have : ‘berzelium.’ The research is being aided by the Carnegie Insti- tution. Baskerville and Zerban are at present with removing entirely from the new been designated ‘carolinium’ and Concerning the second problem assigned your committee for supervision, namely, the work of preseodymium, it would make the following re- port: Baskerville and G. MacNider did not suc- ceed in proving the complexity of that constituent [N.S. Vou. XXI. No. 524. of the old didymium. The methods of attack were: (1) Production of higher oxides by fusion with sodium dioxide; (2) fractional solution of the well known black oxide in hydrochlorie acid at variable temperatures; and (3) fractional pre- cipitation of the oxalate at different temperatures —zero, 20°, and 100° C. A Zeiss comparison spec- trometer, purchased by a grant from the council, was used for controlling the progress of the work, which will be continued, We, therefore, beg leave to report progress. Respectfully submitted, CHAS. BASKERVILLE, Capt. Sins Honz, F. P. VENABLE. On Cave Fauna. Owing to the absence of the secretary of your committee in the caves of Cuba during the last meeting of the association, a report on progress was omitted at the St. Louis meeting. Since the last report the following papers based in part at least on material collected with the grant of three years ago have been published: 1. ‘Report on the Fresh-water Fishes at West- ern Cuba.’ Bull.

Further work on this form should consist in noting the changes of the eyes in individuals reared in the light. Several papers are in preparation. Several years ago a Mr. Donaldson died in Scot- land, owner of a farm of somewhat over 182 acres of land near Mitchell, Ind. He was apparently without legal heirs. Suit was brought by the state of Indiana to have this farm escheat to the state. The suit was contested by Scottish heirs of Mr. Donaldson, but was won by the state. This farm is in the midst of the cave region of the Cuba,’ JANUARY 13, 1905.] Ohio Valley, to which belong Wyandotte and Mam- moth caves, and is much more ideally adapted for experimental work with cave animals than either of the larger caves. On it are easily accessible some very large rooms provided with water. On it are the only entrances to an underground stream which I have followed over a mile by actual measurement and from which all of my material of Amblyopsis was obtained. Finally on it the stream comes to the surface under condi- tions that make the farm admirably adapted for surface ponds and pools to rear cave animals in the light. The American Association at its Washington meeting passed resolutions asking the state of Indiana to set this aside for a state reservation, and part of it for an experimental farm for the investigation of cave animals, ete. In the winter of 1902 the state legislature passed a bill in part as follows: “The title of all such lands shall be and remain in the state of Indiana, and such lands shall be devoted to educational purposes. “The control and management of all such lands shall be vested in the trustees of Indiana Uni- versity and such lands may be used by said trus- tees for any proper educational purposes. “Said board of trustees may in its discretion set off any portion of such grounds to the use of the state board of forestry or to that of Purdue University, or any other educational or scientific institution of the state.” In the meanwhile the heirs appealed the suit to the supreme court of Indiana which also ruled in favor of the state in August of 1903. ‘lhe heirs thereupon asked the same supreme court to grant them a new hearing before itself and there the matter has been suspended for over a year. It seems very probable that this farm will ulti- mately pass into the possession of the Indiana University and can then be used for experimental work with cave animals. I have personally received a grant from the Carnegie Institution which enabled me to make further attempts to secure the embryological ma- terial of the Cuban blind fishes, without, however, being entirely successful in securing this much- desired series of embryos. The most notable and systematic piece of cave work so far undertaken is in preparation by my assistant, Mr. A. M. Banta. He is making a phys- ical and biological survey of Mayfield’s cave, situated but five miles from my laboratory. He has determined the distribution of animals in the cave, the per cents. of the total cave fauna that is SCIENCE. 61 accidental, occasional or permanent. He is working in the interrelation of these forms and determining the modifications of the permanent members of the fauna to adapt them to cave life. This piece of work will form a base line for future work with the fauna of caves, and it is very de- sirable that Mr. Banta be enabled to make similar studies of a few selected caves in the various cave regions of America. It is recommended that the committee be con- tinued and that an appropriation of $100 be made to continue the work of the committee. Respectfully submitted for the committee. C. H. E1cENMANN, Secretary, THEO. GILL, S. H. Gace. On Indexing Chemical Literature. The committee on indexing chemical literature, appointed by your body at the Montreal meeting in 1882, respectfully presents to the Chemical Sec- tion its twenty-second annual report, covering the eighteen months ending December 1, 1904. Works Published: ‘A Select Bibliography of Chemistry, 1492- 1902,’ by Henry Carrington Bolton, Second Sup- plement. Smithsonian Miscellaneous Collections, No. 1440, City of Washington, 1904. This supplement brings down the literature of chemistry from the close of the year 1897 to the close of the year 1902. The author died while the publication was in press and most of the proof- reading, as well as the preparation of the index, was done by Mr. Axel Moth, of the New York Publie Library. In the Arbeiten aus dem Kaiserlichen Gesund- heitsamt, volume 21, pages 141 to 155, appears a critical bibliography of sulfur dioxid in wine, by W. Kerp: Indexes on the literature of gallium and of ger- manium, by Dr. Philip E. Browning, of New Haven, Conn., have been completed and accepted by the Smithsonian Institution for publication. An index to the literature of radium and radio- activity has been completed by Dr. Chas. Basker- ville and Mr. Geo. F. Kunz, and is expected to appear in a bulletin of the United States Geolog- ical Survey, as an appendix to a paper by Mr. Kunz on radium. An index to the literature of solubilities, 1875— 1903, by Mr. Atherton Seidell, of the Bureau of Soils, is now in the hands of the committee. The index to the literature of glucinum by Pro- fessor Chas. E. Parsons, of New Hampshire Col- lege, Durham, N. H., has been completed. 62 SCIENCE. As is well known for a number of years such bibliographies as have been recommended by their committee have been accepted by the Smithsonian Institution for publication in its ‘ Miscellaneous Collections.’ It has thus been possible to put into the hands of specialists and others valuable in- dexes which could not otherwise be rendered ac- cessible. That it is not deemed possible for the Smithso- nian Institution to continue this work appears from the following extracts from correspondence with Mr. S. P. Langley, Secretary of the Institu- tion: “The institution has found it necessary to dis- continue for the present the publication of sepa- rate indices to the literature of the various chem- ical elements. “The resources of the Smithsonian Institution, as is well known, are limited, and must be dis- tributed over a very considerable variety of in- terests. When, failing congressional aid, it seemed that the project of the International Cata- logue of Scientific Literature could not proceed without the establishment of an American re- gional bureau, I decided to assume this on the part of the Smithsonian Institution, and the allot- ment made for this purpose is practically all that can be spared for any current indexing work. “The various bibliographies to chemical ele- ments and other chemical indexes could not, ap- parently, have veen projected upon a plan that would fall in with this catalogue, since at the time they were begun no one had the catalogue in mind. Accordingly, I find that the earlier ones come down to 1887, 1893, 1896 and 1900, and a more recent one, thorium, down to 1902. This brings up the entire question of retrospective indexing and_bibliog- raphy. previous to the date 1901, designed to cover the period prior to the beginning of the interna- tional catalogue. Such a project for all science should, of course, only be taken up after mature deliberation, and could only be carried through by international cooperation. Meanwhile it seems prudent for the institution to await a careful consideration on the part of all interested in the whole subject, chemistry, being of course, but one of the large group of sciences whose workers must be considered. In view of these considerations, the importance of which you will, I am sure, rec- ognize, I am constrained to leave the entire matter in abeyance for the present.” In view of the above it may be questionable whether the work of this committee has not been completed as far as it is possible to carry out the oflices for which it was originally constituted. It LN.S. Vou. XXI. No. 524. may, however, be wise to continue it for another year, to await developments. In conclusion, references should be made to the great loss sustained by the-committee, the sec- tion and the association, in the death on November 19, 1903, of Dr. Henry Carrington Bolton, who from the first appointment of this committee has been its chairman. The work of Dr. Bolton in the field of chemical and alchemical bibliography needs no encomium; it is invaluable to all work- ers in these fields. Jas. Lewis Howe, Chairman, F. W. CLARKE, H. W. WILEY. On Electrochemistry. A pure iridium electrode was purchased, and some rhodium powder. It was deemed advisable to precede the electrochemical portion of the in- vestigation by a study of the chemical phenomena caused by these metals when no current passed. With this in view experiments have been made on the action of these metals on formic acid. These have confirmed the qualitative results of Deville and Debray, that the decomposition products are essentially carbon dioxid and hydrogen under these circumstances and not carbon monoxide and water. The reaction starts at a higher tempera- ture than one would have supposed from the statement of Deville and Debray as to ‘gentle heating.’ The rate of decomposition of liquid formic acid is constant when the decomposition products are allowed to pass off, but there is need of the further study of the behavior of the acid in a closed space. This will be taken up next, and after that the electrolysis. The effect of the iri- dium on the chemical and electrochemical equi- librium between chlorine and water will also be studied. For this work your committee asks for a grant of an additional sixty dollars. The committee begs leave to report progress. Respectfully, WILpER D. BANCROFT, Epear F,. SMITH. On Grants. The committee on grants recommended that the following grants be made for the year 1905: To the Committee on Anthropometry, $50. To the Committee on Electrochemistry, $60. To the Committee on Cave Fauna, $100. To the Concilium Bibliographicum, $100. To W. H. Dall, to assist in republishing a rare work on mollusks, the amount to be repaid in the printed volumes, $50. L. O. Howarp, Chairman. JANUARY 13, 1905.] On the Walter Reed Memorial. At a meeting of the association held in Wash- ington, a committee was appointed, of which I was made chairman, to take such measure as might be found wise for securing a permanent memorial of Major Walter Reed, U. S. A., in recognition of his important services to humanity. Acting under this authority, it was at length found ex- pedient, after several preliminary meetings, to form an incorporation in the city of Washington to hold such funds as might be contributed. This incorporation is now endeavoring to raise the sum of $25,000, of which the income may be paid to Mrs. Reed and the principal may be devoted to a permanent memorial of Dr. Reed. More than $13,000 has been subscribed already, a large part of this amount coming from the medical profes- sion. This is all in addition to the action of Con- gress, which has given, on the representations of your committee, an unusual pension to Mrs. Reed. The effort is now making to secure the additional sum of $12,000, and the cooperation of all mem- bers of the American Association for the Advance- ment of Science is urgently desired. Yours respectfully, DANIEL E. GILMAN, Chairman. On the Relations of the Association to the Journal * Science.’ We beg to report that the arrangement by which Scrence publishes the official notices and proceed- ings of the association and is sent free of charge to the members in regular standing on payment of two dollars for each appears to give satisfac- tion.

Boston, Ginn and Company. Pp. xiv + 463. A characteristic feature of mathematics in the last half century is the increasing atten- tion paid to the foundations and rigorous de- velopment of this science. In analysis this movement began with Gauss, Cauchy and Abel in the early years of the nineteenth cen- tury and found its greatest exponent in Weier- strass. The movement thus begun has been continued by such men as Riemann, Dede- kind, Hankel, Cantor, Jordan, Dini, Stolz, Harnack, Peano and a host of younger men. As a result of these investigations it was found that much of the reasoning hitherto employed and in current use among mathema- ticians was either worthless or required to be : JANUARY 13, 1905.) modified, restricted or completed. It thus be- came necessary to rewrite textbooks on an- alysis or to prepare new ones more in harmony with the new teachings. In this way arose the new edition of Jordan’s ‘ Cours d’ Analyse’ and Harnack’s edition of Serret’s ‘ Calcul,’ as well as the new works of Stolz, ‘ Allgemeine Arithmetik, and ‘Grundziige’; Tannery, ‘Théorie des fonctions d’une variable’; Dini, ‘Fondamenti per la teorica delle funzioni di variabili reali,’ In England and America more progressive teachers have felt for some time the need of a modern text-book on the calculus, which is at once rigorous and elementary. The task of writing such a work is not easy. On the one hand, it is necessary to avoid the worth- less and even vicious forms of reasoning which mar so many elementary treatises and which are simply intolerable to one educated accord- ing to modern standards of rigor. On the other hand, the author must not introduce subtilties of reasoning and logical refinements beyond the needs and comprehension of those who are to use the book. The volume under review is an attempt to solve this difficult problem. To our mind the efforts of its author have been abundantly crowned with success. In perusing Dr. Gran- ville’s book one feels throughout that the author has in mind the requirements of mod- ern rigor. The demonstrations, it is true, often rest on intuition; but this is necessary in a first course, as all will admit. They are, however, usually correct as far as they go, and free from the defects we have mentioned above. We believe the present volume is eminently a safe book to put in the hands of the beginner. He will get no false notions which afterwards will have to be eradicated, with much difficulty; he will, on the other hand, acquire a considerable acquaintance with the principles of the calculus and a good working knowledge of its methods. We make now a number of criticisms and suggestions. The definition of limit given in § 29 is not the one given by Cauchy and Weierstrass and now universally accepted. Looked at care- fully, we see it supposes that all variables are SCIENCE. 65 functions of an auxiliary variable, the time. This leads to unnecessary complications in the definition of the limit of a function in § 32. We believe the strict Weierstrassian definition should be given and used. As an aid to comprehension, the author’s notions in these articles might prove useful. In § 34 the notion of a graph is explained; but not with sufficient care, to our mind. How is the reader to know from their graphs that x and log « are continuous functions? The three proper- ties of the exponential function given in this article result from their arithmetical proper- ties and not from their graph, as the author seems to imply. The definition of the derivative given in § 41 is not satisfactory; what the author really defines is the differential coefficient at a point. It is their aggregate that forms the derivative. In §55 the author has avoided an error which is very prevalent. His passage to the limit is, however, not completely justified. He has yet to show that ca AG fe NO Saline = alin ; Av=0 Av Axr=0 Ax The demonstration in § 56 should, it seems to us, be replaced by a simpler one. The au- thor obtains the equation _ dy dx a dx dy ) and then remarks: if dx/dy + 0, we have He should see that there can be no need of making the further assumption, dxr/dy +0: for if it were, the equation (1) could not exist. In §133 the author introduces a double limit without any explanation. As_ such limits are used in connection with double in- tegrals, § 231, seg., they should be explained with care. The footnote on page 194 is un- intelligible to us and certainly will give rise to misapprehension. The theory of total differentiation does not meet our approval at all. The author has treated the subject from the standpoint that the variables x,, x, --- 2, are all functions n 66 SCIENCE. of some one variable. Instead of true total differentials, he gets total derivatives. The du in $187 are not total differentials, but differ- tials of functions of one variable. In the dif- ferentiation of implicit functions the author assumes merely the existence of the partial derivatives. He should assume also their con- tinuity. The form of demonstration is bad, as it requires him to assume (tacitly) the ex- istence of the very thing he is seeking, viz., dy/dx. In the treatment of envelopes, § 141, the author does not as usual give sufficient condi- tions for the validity of his reasoning, but contents himself with the vague statement in a footnote that the process is all right ‘in all applications made in this book.’ This blemish, which a few lines will remedy, should be re- moved in another edition. The definition of an infinite series given in § 147 is not felici- tous. In avoiding the lax definition usually given the author has gone to the opposite ex- treme. The simplest way seems to be to con- sider a,-+a,+a,+, ... in inf. as a symbol to which a meaning is attached as to other symbols, as > <=, ete. The solu- tion of Ex. 3, § 152, is not quite rigorous, as it postulates the covergence of G. In § 160 undefined arithmetical operations are per- formed on series. We can not agree with the author that the remainder in Taylor’s series for several vari- ables is too complicated to be given. The treatment of maxima and minima can be made much more complete without complications or difficulty. The reasoning given at the bottom of page 248 can be made not only ‘ plausible,’ but entirely conclusive, using no more space that that required by the author. In the reduction of indefinite integrals the author proves the trivial formule f(a + dv— dw) = foaw + fa — faw, faa— a fae, but omits entirely the demonstration relative to the transformation of the variable. This is all the more surprising as this transforma- [N.S. Vox. XXI. No. 524. tion is constantly employed, even in establish- ing important theorems. Two chapters, XXIX. and XXX., are devoted to definite integrals. In the first we arrive at the notion of a definite integral by means of the notion of area; in the second, by means of the limit of asum. In our opinion the first treatment is not only superfluous, but should he entirely omitted on several counts. The relatively few blemishes in this work, the reviewer is glad to state, will be removed in the next edition. JAMES PIERPONT. YALE UNIVERSITY. The Study of the Atom, or the Foundations of Chemistry. By F. P. Venasie. Easton, Pa., The Chemical Publishing Co. Pp. 290. The history of an important scientific theory is an interesting study, where it is possible, as it often is, to trace the orderly development of that theory from stage to stage. The evo- lution of the atomic theory is a subject which has claimed the attention of many writers, and the story has been told so often and so well in works on the history of chemistry, that one wonders whether it is not familiar to most chemists. A careful perusal of this book does not disclose any new point of view, or any- thing new in the method of treatment, though the matter is generally presented in a satis- factory manner, especially Chapter V., which deals with the periodic system. In the last chapter of the book the author considers the most recent hypotheses regarding the constitu- tion of matter by J. J. Thomson, Rutherford and others. The book is generally clear, con- servative in tone and, on the whole, well-pro- portioned, though 75 pages, or one fourth of the contents, seems rather too much to de- vote to the conception of the atom before the time of Dalton, especially as this material must be taken entirely from secondary sources. The book may be commended as a good sum- mary for students. BE. T. AntEn. SOCIETIES AND ACADEMIES. NEW YORK ACADEMY OF SCIENCES. SECTION OF GEOLOGY AND MINERALOGY. Tue section was called to order at 8:15 P.M., November 21, 1904, with Vice-president Kemp in the chair and forty persons present. JANUARY 13, 1905.] The first paper of the evening was by Pro- fessor J. J. Stevenson, upon ‘ The Island of Spitzbergen and its Coal,’ and was illustrated by lantern slides. In introducing his subject, the speaker described briefly the coast of northern Norway and its geology, and referred in some detail to Bergen, Hammerfest and other cities. Spitzbergen was then taken up, and its coals and their geological relations were passed in review. The coal beds are of Jurassic age, and the coal is peculiar in that it partakes of the characters of the lignites as well as of the true coals. The second paper on the program was by Professor James F. Kemp, on ‘ The Titanif- erous Magnetite in Wyoming. On account of the lateness of the hour, the speaker pre- sented his topic only in abstract. The mag- netite occurs in two places, fifteen and twenty miles north of Laramie, Wyoming, the former and smaller occurrence being near the Shan- ton ranch, the latter and larger being on Chug- water Creek. Both are in wall-rock of an- orthosite which is practically indistinguishable from anorthosite occurring in the Adiron- dacks. The ores range from 20 per cent. to 40 per cent. TiO,. Thin sections show that they contain green spinels, and one slide pre- sents much olivine. They can be most reason- ably explained as intrusive dikes. In this view the speaker agreed with Waldemar Lind- gren, who has published a brief note regarding them. James F. Kemp, Secretary pro tem. Tue section held a special meeting Decem- ber 2, 1904, with Vice-president Kemp in the chair and two hundred members and visitors in attendance. The meeting was called to order at 8:25 p.m. and the program of the evening was at once taken up. This consisted of a lecture by Professor Albrecht Penck, of the Imperial University at Vienna, who is an honorary member of the academy. The speaker discussed ‘ The Glacial Surface Features of the Alps,’ and gave a brief sum- mary of some of the results of the twenty years of masterly work which has been done by him and under his direction in the Tyrol. Professor Penck described in popular language SCIENCE. 67 the nature of the valleys of the Alps and showed by means of lantern slides and a dia- gram how the glaciers have widened and deepened portions of their rocky basins and produced lakes. After a vote of thanks to the distinguished guest of the evening, the section adjourned. Epmunp Orts Hovey, Secretary. THE PHILOSOPHICAL SOCIETY OF WASHINGTON. Tue 592d meeting was held December 10, 1904. The first paper was read by invitation by Mr. H. H. Kimball, of the Weather Bureau, on ‘ Variations in Insolation and in the Polar- ization of Blue Sky-light, during 1903 and 1904.2. Observations with an Angstrém pyr- heliometer have been maintained by the Weather Bureau at Washington since April, 1908. Comparison with previous observations at Providence, R. I., and Asheville and Black Mountain, N. C., indicate that the quantity of solar radiation reaching the surface of the earth on clear days during 1903 was consid- erably less than during 1902 and 1904, the deficiency from April to September being 16 per cent. as compared with 1902, and 9 per cent as compared with 1904. Observations with a Pickering polarimeter indicate that there have been corresponding fluctuations in the polarization of blue sky- light, the percentage of polarization at a point on a vertical great circle passing through the sun and 90° from it, having averaged 49.6 per cent. from May to October of 1904, as compared with 40.6 per cent. during the same months of 1903. The work of the astrophysical observatory of the Smithsonian Institution and numerous European observations were quoted, showing similar deficiencies in insolation, in the trans- missibility of the atmosphere, and in the polarization of blue sky-light, during 1903. The subject was considered to be one well worthy of investigation by meteorologists. Mr. J. F. Hayford, of the Coast and Ge- odetic Survey, presented some recent results on ‘The Computation of Deflections of the Vertical from the Surrounding Topography.’ 68 SCIENCE. Deflections may be due to irregularity of density within the earth or to attraction of parts of the earth above the surface of the mean spheroid. By an ingenious method, partly graphical, the author had found it prac- ticable to take account of the influence of all known topographical features on the plumb- line at more than 200 stations; it is usually necessary to consider all the land-masses with- in 2,500 miles of the station. When these computed deflections from known causes are combined with the deflections found from geodetic measurements, the quantities to be accounted for by irregularities within the earth’s surface are usually much greater than had been supposed heretofore. Cuartes K. Wrap, Secretary. MICHIGAN ORNITHOLOGICAL CLUB. Tue Michigan Ornithological Club held its last quarterly meeting for 1904 at the Detroit Museum of Art on December 2.

INTERESTING AND IMPORTANT FACTS. In Powell’s ‘Truth and Error’ a_philo- sophie distinction is made by giving special [N.S. Vou. XI. No. 524. definitions to the terms property and quality. A property is an essential characteristic con- sidered in itself; a quality is a characteristic considered in relation to man. Thus the ductility of iron is a property; its utility a quality. The form and coloration of a tree are properties; its beauty or ugliness is a quality. Iron’s property of ductility, when thought of in connection with human needs, is a factor of its quality of utility; and the properties of the tree, when viewed from the standpoint of man’s esthetic sense, are quali- ties. This simple distinction is of far-reach- ing application, because properties are the domain of science and qualities the domain of art. Pure science (with a reservation in respect to anthropology) is not at all con- cerned with qualities, and when the investi- gator deals with them he passes into the field of applied science, or the arts. Failure to recognize this distinction leads to much con- fusion of thought and expression. One of the milder or less harmful, but at the same time most conspicuous, manifesta- tions of this confusion is connected with the word interesting. Not unfrequently an essay ostensibly and mainly scientific will contain the statement that an object, or relation, or other phenomenon is ‘ interesting,’ the context indicating that interest is supposed to inhere in the phenomenon. As a matter of fact, interest is a mental attitude of the observer, and the adjective ‘interesting,’ though ap- plied to the phenomenon, describes only the observer’s relation to it. There are, of course, many legitimate uses of the adjective, and some of these occur in scientific writings. When an author, for example, declares that the insect habits he is about to deseribe are interesting to students of the psychology of the Bombocoreide, it is clear that he does not deceive himself by supposing that he has named a property of the phenomena. Something similar may be said of important, valuable, ete., when employed in scientifie de- scription. In common with novel, pertinent, significant, and the like, they indicate the rela- tions of phenomena to the condition of human knowledge. Just as each observed fact has at some time, temporarily, the quality of novelty, } } | | JANUARY 13, 1905.] so each fact and inference may in some phase of the progress of knowledge serve to explain the previously unexplained, and thus have importance or comparative value. Apart from such temporary and humanistic rela- tions, all facts are equally important or equally unimportant. When, therefore, an author makes the bald statement that a fact is ‘im- portant, he ascribes to it a quality and not a property; and he is self-deceived if he thinks of the importance as an essential character- istic. It conduces to clear thinking as well as clear writing if one fortifies the use of ‘ in- teresting’ or ‘important’ by pointing out the relation which endows the indicated fact with interest or importance. When that has been done the need for the adjective often disap- pears; and if it can not be done, the adjective is a meaningless platitude. G. K. Gitpert. WASHINGTON, D. C. SPECIALIZATION, IGNORANCE, AND SOME PROPOSED PALLIATIVES. I sre leave to use the columns of Science to express a few ideas which may strike some readers as strangely naive, but which have been incubating in my brain for a term of years, and must now at length find some mode of deliverance. I speak as one of that large class of unfortunates who aspire to contribute a few small stones to the temple of knowledge, but who are forced to give so much time to purely routine work that little is left for better things. And that precious little remnant of our time—how do we employ it? Largely in misspent energy and unproductive eficrts; not in the quest of knowledge, but of the means of acquiring knowledge; not in learning facts, but in learning how to learn! After we have deducted the time spent in purely mechanical operations, in developing our technique and in digesting the ever-growing literature of our particular little fraction of a sub-science, how much remains of those brief moments spared from the struggle for bread? Is it a wonder that ‘general culture’ suffers, when even our sister sciences are neglected, or that specializa- tion so often results in an intellectual isola- SCIENCE. 69 tion, fatal alike to the scientist and the man? Platitudes?—of course they are! Who has not deplored these conditions? But we all resign ourselves to them as inevitable, just as we do to a social order which tolerates boss rule, ‘Standard Oil’ and the inheritance of poverty or riches. Who has not wished to halt the march of discovery long enough to allow himself to ‘catch up’? And, seriously, would it be a misfortune if we should be com- pelled to pause for a moment in the exploita- tion of new facts, and properly assimilate the ones we have? But this is not the burden of my modest message. One can not but marvel at the absence of any adequate bureau of exchange among specialists in different fields of knowledge. We have our societies, it is true, where papers are presented which are oftentimes too technical even for the limited circle of members—all fellow specialists in a single science. We have our journals, congested with contribu- tions, good, bad and indifferent. But which one of us can follow all the technical journals of his own specialty, even though his path be blazed by international bibliographic cata- logues? We have our reviews and year-books and Jahresberichten, in which the topics treated are apt to gain in technicality in pro- portion to the degree of abridgment. Various semi-popular periodicals doubtless do a splendid work in making accessible some of the more general conclusions of science, but their eontents are necessarily fragmentary and uncoordinated. In our higher educational institutions we find specialists engaged in two chief pursuits: giving instruction to students, and conducting research. A third possible function of the faculty seems never to be fully recognized, namely, mutual enlightenment. Why is there often such utter isolation between various departments? Why has there not been estab- lished any recognized clearing-house for the exchange of expert knowledge? Much of such exchange doubtless occurs in a desultory and haphazard way, through ordinary social inter- course, so that a man of requisite personal and social gifts may receive and impart much of value. And doubtless various public lecture 70 SCIENCE. courses do something toward meeting this But why not organize in every uni- versity an inter-departmental congress, in which members of the various departments shall present, in as palatable form as possible, the problems and discoveries of present interest in their respective branches of learning? On the face of things it would seem that such an arrangement would necessarily result in an added stimulus and a broader horizon for each member of the staff, and a greater solidarity for the whole. An objector will doubtless be prompt to point out that the above plan, though plausible on paper, would, for one reason or another, be quite impossible in practise. that no suggestion which offers the least hope of lessening the baneful effects of over-special- ization ought lightly to be dismissed. Nor should I be surprised by the quite different criticism that my idea utterly lacks novelty, that it has long since been threshed over by educational experts, perchance received a fair trial somewhere. In reply, I could but cite my own ignorance of these facts as a fine illustration of the very conditions which I have deplored. need. But there is another idea which I cherish just as tenderly—one equally chimerical, may- hap. It is nothing more nor less than the es- tablishment of a sort of human encyclopedia as an adjunct to our libraries. How much of our ignorance is due to the inaccessibility of knowledge! How many questions we allow to pass unanswered, rather than grope blindly The thought lies near to hand that some one could save us that trouble-—some one who would not have to grope. But who? The plain man sends a query to his daily paper, and receives an answer which we hope is more trustworthy than the editorial opinions or news items on the same sheet. Or he may have the temerity to write to an expert, who may be good-natured enough to reply. amongst unfamiliar volumes! But where in our educa- tional system is the man or body of men whose recognized function it is to answer questicns ? Teachers we have by the thousand, employed to impart knowledge in accordance with cer- tain more or less stereotyped courses of study, I can only reply _ [N.S. Vou. XXI. No. 524. but where are the men whose business it is to tell us just those things for which we happen to be seeking? The scientific departments of our government, it is true, give much expert advice on various matters, in reply to corre- spondents, and here, indeed, we find our most instructive models. But their scope is ob- viously limited. Suppose that one of our great libraries were to employ a staff of consulting experts, men of the rank of college professors, whose duty it should be to furnish definite bits of informa- tion in response to legitimate questions, or at least to guide the seeker on his way. The cost of maintaining such a library would doubtless be vastly increased, perhaps doubled -—I leave that for the professional librarian to compute. But over against this added cost could be set the untold hours saved to the student or the layman, searching in un- familiar fields, and the vastly greater facility of the diffusion of. knowledge. My suggestion might easily be caricatured into the proposal that the learner should henceforth dispense with books. Quite otherwise, it is my main object to enable him to do more reading and less groping’; to peruse pages of text, instead of card catalogues and tables of contents; to economize time, and to minimize the loss of energy through friction. Tn the case of a university library, could not such relations be maintained with the faculty as to permit of members of the latter body being called in for expert advice, not sporad- ically, but as a part of the organic system? This would throw an additional burden upon the teaching staff, which would, of course, need to be increased numerically. But would not such a function compare favorably in use- fulness with the teaching of various prescribed subjects to apathetic learners? To the over- burdened specialist, such a system would serve the same end as the plan first proposed, giving him more ready access to other fields of thought, and minimizing the evils resulting from the increasing differentiation of knowl- edge. But here again I fear that the experts may smile at my modest suggestion, either as be- ing utterly impracticable, or as quite devoid ie ee JANUARY 13, 1905.] of novelty or originality. If so, I can but humbly acknowledge my ignorance, adding once more that this unhappy condition merely strengthens my case! Francis B. SuMNER. ULTRA-VIOLET LIGHT IN PHOTO-MICROGRAPHY. To tHe Eprror or Science: Apropos of Dr. Cleveland Abbe’s letter in a recent issue of Science, I would eall the attention of your readers to the fact that the developments in the use of utra-violet light in photo-micrography with apparatus designed at Jena is described in some detail in Hngineering (London), for December 2, 1904, page 760. Ciirrorp RICHARDSON. HOW DOES ANOPHELES BITE? In a recent number of Science Professor Washburn, in the course of some remarks on the mosquito exhibit at St. Louis, prepared by me for the New Jersey State Museum, ques- tions the accuracy of a figure of Anopheles in the act of biting. JI do not understand him to say positively that the figure is inac- curate, only that it had been his belief .that the biting position resembled the resting posi- tion more nearly. The figure in question, which was a large colored one calculated to attract the attention of the passers-by, was intended to duplicate the picture given by Nuttall and Shipley in their work on Ano- pheles, its structure and habits. It is really a very accurate copy of their plate and the position in my chart is just exactly as pub- lished. This is an explanation, not a justifi- cation; if the figure is wrong it should not have been put on exhibition in that way; but is it wrong? When I read Professor Washburn’s note I tried to recall my own experience with Ano- pheles. I recall distinctly, watching speci- mens bite on several occasions, and particu- larly at Cape May, where Anopheles crucians was very plentiful in 1903 and bit freely dur- ing the early morning hours. This habit is unusual in the genus and attracted my atten- ‘tion, so that I gave the insects every oppor- tunity to bite; yet, while I can recall dis- tinetly all the surrounding circumstances, I do not recall just what position the insect assumed when biting. I questioned in turn SCIENCE. V1 every member of the field and office force, and found that they were equally uncertain in the matter. All of them had been bitten and all of them were able to recall specific occa- sions where they watched the insect bite, yet none of them would say positively just what the biting position of the insect really was. During the summer of 1902 Dr. Herbert P. Johnson studied Anopheles for me near Newark, ‘N. J., and kept a number of the in- sects in confinement, allowing them to bite from time to time, and of course watching the operation. I wrote him to the St. Louis University, where he is at present engaged, and received an answer as follows: “ While I have not so distinct a mental picture of the operation as I would like to possess I am very confident he [Professor Washburn] is wrong. The biting attitude he mentions would be a most extraordinary one, and for this reason: it is obvious that the mosquito pumping ap- paratus must penetrate the epidermis before any blood ean be drawn and the epidermis is made up of many layers of cells. To thrust its lancets in obliquely is evidently to encoun- ter more resistance, do more work, and with less prospect of suecess than to thrust verti- eally through the many layers of cells of the epidermis. If there is an easy way of doing a thing, nature does not ignore it for a more difficult way. pheles could introduce its bill vertically and still keep it in line with its body, would be The only way in which Ano- for the body to assume the vertical position, which I have never seen it do. It is always somewhat oblique.” Mr. Henry L. Viereeck, who spent the entire summer at Cape May for me and who espe- cially studied A. crucians, writes: “ In biting Anopheles crucians stand like A. punctipennis as shown in Berkeley’s figure 17; that is, with the body and beak nearly in a straight line and at an angle somewhat greater than 60° to the surface. The disposition of the legs during the act I can not recall exactly, but I feel quite sure they were very much as in the figure I have referred to.” These communications were hardly satis- factory and we looked up every reference that was available, only to find that no one who 72 SCIENCE. has written upon the subject, whose works we had in hand, spoke definitely on the position of Anopheles in actually biting. Nuttall and Shipley deseribe the bending of the proboscis, and in fact the entire mechanism of biting, and other authors are almost as detailed as they; but to the position, no one seems to refer. In the hope of getting other information [ wrote to Dr. L. O. Howard, and received this reply: “I never saw Anopheles bite but once, and that was in the dusk while I was sitting on the platform of a railroad station at Fresno, Cal. My impression was that the beak was not in the plane of the body; but that the head was bent downward. Mr. Pratt, when he was living in Virginia, was frequently bitten by Anopheles, and tells me that he has a positive recollection that the head was bent downward and that the hind legs were curved upward.” I wish it distinctly understood that this is not a contribution to knowledge. It is an illustration of how many men may make ob- servations in certain lines and absolutely ig- nore the most obvious points. It is also in- tended as a suggestion to those who may have made and recorded direct observations on this point, to publish their experiences. Joun B. SmirH. RUTGERS COLLEGE, New Brunswick, N. J. December 22, 1904. SPECIAL ARTICLES. THE DISCUSSION IN THE BRITISH PARLIAMENT ON THE METRIC BILL. Tuere lies before us a reprint from the Parliamentary Debates in the House of Lords on February 23, 1904. The order of the day was the second reading of the bill for the com- pulsory introduction of metric weights and measures into the United Kingdom of Great Britain and Ireland. We will make some ex- tracts from the discussion which will show the present conditions over there and which will interest us because it is universally admitted that the adoption of the metrie system by one branch of the English race will secure its adoption by the other. The reading was [N.S. Vou. XXI. No. 524. moved by Lord Belhaven and Stenton, but the principal advocate of the bill was Lord Kelvin. In order to show how great change had taken place in public opinion on the measure in recent years, as compared with the time not long ago when the chief argument of the op- ponents of the bill was that public opinion was not yet ripe for it, the noble lord presented petitions from thirty town and city councils, representing a population of over 8,000,000, from fifty chambers of commerce, thirty retail dealers’ associations, forty-three trades unions representative of 300,000 workers, sixty teach- ers’ associations, inspectors of weights and measures in eighty districts and a large num- ber of individual signatures, bringing the total number of individuals represented to 333,000. A nearly equal number additional were prom- ised within a week, the Liverpool Chamber of Commerce sending theirs separately by Lord Avebury, together with several chambers of agriculture. The difficulties alleged to be experienced by foreign countries in making the change were declared non-existent. His Majesty’s representatives abroad at the time stated the change was made without much difficulty; though some countries were more rapid than others, there never had been any desire to return to the old system, and the adoption of metric weights and measures had assisted the development of trade. Switzer- land commenced to use the metric system eighteen months from the passing of the law. There was no great difficulty found there in the towns, but it was some time before it was adopted in remote country places. In Ger- many it was adopted more quickly than any- where else. Two years and one month were allowed, and the interval thus granted was sufficient to insure the adoption of the new system in all details; it was an accomplished fact by the day named. There is no desire to go back to the old system, and the change has contributed to a rise of German trade and commerce, foreign trade deriving much bene- fit. There are some persons who object from a dislike to mental effort, and who prefer to muddle on with the British system described by the prime minister as ‘ arbitrary, perverse and utterly irrational.’ To these I reply that JANUARY 13, 1905.] the metric system is bound to be adopted sooner or later, and that personal inconven- ience for a few days should not be allowed to interfere with a measure calculated to promote the trade and prosperity of the country. We have had nine years of permission to use the metric system without thereby rendering ourselves liable to punishment for a breach of the law, and experience has proved that the change from the system that has been so long in use in this country to a new system can not be made over the whole country voluntarily. It is a case for compulsion, and I think the legislature will be thanked by the country for having applied compulsion. In Germany, France and Italy no inconvenience has re- sulted from the introduction of the metric system, and there has never been such a thing as a complaint. The change in Germany oc- cupied only two years. JI have in my hands a statement by Sir Wm. Ramsay, in which he wrote: “I was in Germany during the change there; it gave no trouble whatever and was recognized within a week.” It is interesting to know that the decimal system, worked out by French philosophers, originated in England. In a letter dated November 14, 1783, James Watt laid down a plan which was in all respects the system adopted by the French philosophers seven years later, which the French government sug- gested to the King of England as a system that might be adopted by international agree- ment. James Watt’s objects were to secure uniformity and to establish a mode of division which should be convenient as long as decimal arithmetic lasted, a thing we may consider as absolutely settled. I hope this bill will be sent forward with full pressure to the other house, 333 members of which have declared themselves in favor of it and ready to support it. In introducing the bill, Lord Belhaven and Stenton recalled some of the testimony given in the blue book, known as the ‘ Report on Weights and Measures,’ made to the house of commons July 1, 1895. That report contained three recommendations, viz: (a) That the metrical system of weights and measures be at once legalized for all purposes. SCIENCE. 72 (>) (bo) That after a lapse of two years the metrical system be rendered compulsory by act of parliament. (c) That the metrical system of weights and measures be taught in all public elementary schools as a necessary and integral part of arithmetic, and that decimals be introduced at an earlier period of the school curriculum than is the case at present. Of these recommendations the first was com- plied with by the permissive act of 1897, which made the use of the metric system in trade lawful (it was previously illegal to use it), and the third was adopted under the educa- tional code of 1900. The second is in the bill now before us. An important point in the history of this subject is, that in August, 1902, there was a colonial conference attended by all the premiers of the self-governing colonies, which passed this resolution: “It is advis- able to adopt the metric system of weights and measures for use within the empire, and the prime ministers urge the government repre- sented at this conference to give consideration to the question of its early adoption.” And since that time the colonies have been pushing the matter with great earnestness. The saving of time in education by the use of the metric system is not only in the teach- ing of the tables, but the whole system of com- pound addition, subtraction, multiplication and division, and the system of computation called ‘practise.’ Last year inquiries were made of head masters of schools on this sub- ject, and 197 sent replies, of which 161 said the saving would be one year, 30 said it would be two years, and 6 said that it would be three years. The senior mathematical master of Edinburgh high school wrote: “ An average scholar would save at least a year and a half, probably two. I conceive it to be not only a saving of time, but an economy of mental effort which is incalculable.” The commercial value of the metric system has been reiterated by British consuls in foreign countries for many years. In the Board of Trade Journal, February 15, 1900, the British consul at Amsterdam says: “ The iron and steel manufacturers’ unions of Ger- many have adopted a uniform system of 74 SCIENCE. dimensions based on metric weights and meas- The classifications are making more and more progress in Germany, not in the iron trades alone, but in other manufactures. In the future Germany, and the continent generally, will have a constantly increasing advantage over British manufactures in for- eign countries, unless the metric system be fully and entirely adopted by Great Britain. I may mention as an undoubted fact that the preference which Germany has obtained here over Great Britain regarding railways, bridges and other railway material is mainly owing to the existence of this metric classification.” Other items in the discussion were that Russia had directed her iron and steel works to alter their rolling machinery so as to pro- duce only rods, rails and sheets on a metric seale, that 45 per cent. of British exports were to non-metrie countries and 55 to metric countries (66 per cent. of United States im- ports are invoiced in metric measures). At present Britain has eighty different denomi- nations represented by 155 different kinds of weights and measures, which by this bill will be reduced to thirty denominations repre- sented by fifty-three different kinds of weights and measures, or only one third the present ures. number. Vhe bill was read a third time in the house of lords, May 17, and referred to a select com- mittee to arrange the practical details neces- sary to carry it into effect. It was then passed and sent to the house of commons, and read the first time. This discussion showed that there was a very great popular demand in England for the introduction of the metric system, more than there is in this country at the present time. England is a small country, and the adjacent countries, France, Belgium, IJolland and all Scandinavia use the metric system, hence people in general are brought much more in contact with it than in the United States, where we only touch the metric system directly in Mexico, and even this con- tact is having a decided effect in making the system familiar to our citizens. The principal arguments now relied on by the opponents of the metric system here are that it has not displaced the old measures in [N.S. Vou. XXI. No. 524. countries where it has been legalized, and that its introduction would be a matter of enormous expense. Any one who has had personal ex- perience in foreign travel, or who will take pains to inquire of any of the thousands of emigrants that come among us, will soon con- vince himself that the metric system is the principal system in actual use in trade and ecommerce in European countries. The very large number of working people who appear in Lord Kelvin’s list as advocates of the metrie system are drawn to its support not only by the actual contact with metric- using nations, but also by the handicap im- posed by the British system on getting a useful practical education. This point is increasing in importanee since the complete change of both British and American text-books to the metric system. The absurdity is patent of requiring the workman to use an old system different from that in which all knowledge is gathered by the original workers and com- muniecated to their students, and of which the great mass of operatives are ignorant. The operatives themselves, as soon as they become fully aware of it, demand the possession of this key to knowledge and the higher eduea- tion. We have heard a great deal in the last three years about the enormous expense of adopting the metric system. The great majority of people who talk about this expense do not know anything about the actual use of the metric system, and have not brought one scrap of testimony that supports their views from countries that have made the change, while most of those who advocate the system are in the actual use of it as teachers, investiga- tors, ete. The opponents of the system are in the position of a man who condemns a tool without ever having used it. Now Lord Kelvin said in his argument before the lords that “last year inquiries were made of head masters of schools, 197 sent replies, of whom 169 said the saving of time by teaching the metric system would be one year, thirty said it would be two years and six said it would be three years. The senior mathematical master of Edinburgh high school wrote, that in view of the wearing out of teachers and scholars in JANUARY 13, 1905.] obtaining a knowledge of the British system, the adoption of the metric system would result in not only a ‘saving of time, but an economy ot mental effort which is incalculable. ” Lord Kelvin’s argument applies with even more force to the United States. The com- mittee on coinage, weights and measures say in their report No. 1701, April 21, 1902, made to the first session of the fifty-seventh con- gress: “When we consider there are over 15,000,000 school children in the United States being educated at a public cost of not less than $200,000,000 per annum, the enormity of the waste will be appreciated. In the life- time of a single generation nearly $1,000,000,- 000 and 40,000,000 school years are consumed in teaching a system that as a whole does not agree with any other nation in the world, and which does not offer any advantage whatever to compensate for its complexity. Surely the children and teachers of the country are worthy of quite as much consideration as the temporary personal and pecuniary interests of some manufacturers, who have failed to fur- nish, by either themselves or their representa- tives, any evidence whatever that the manu- factures of Germany or Switzerland have or did suffer any loss whatever by the recent adoption of the metric system in those coun- tries. No one in this country has proposed to affix any penalties legal or otherwise to the use of the customary system, what we do want, and are entitled to work for as citizens, is that the government shall adopt in all its work the metric system, which is already the interna- tional system for a majority of the civilized world.” The American Machinist, of January 14, sums up the matter by saying what is true: “The testimony of men who have kad experi- ence in all parts of the world with both sys- tems in the manufacture of machinery is prac- tically unanimous, that most objections to the metric system are based upon purely imagin- ary difficulties, and that the testimony of men who have not had such experience does not amount to anything. We are constantly asked what advantage will the metric system be to this or that partic- ular business. The whole community is larger SCIENCE. 75 than any part of it, and is entitled to first consideration. We have shown above that one of the largest and most important activities in this country, the business of education, will be enormously benefited, and every other trade or business will also be benefited, by the in- creased effectiveness of mental effert in every direction which is the necessary consequence of substituting a simple and rational system for the complex, irregular and barbarous sys- tem now in vogue.

Tue valuable data concerning the tempera- tures in the free air obtained during the daily ‘soundings’ made at the Prussian Aeronaut- ical Observatory at Berlin, are discussed by J. Homma in the Meteorologische Zeitschrift for October, 1904. The observations considered are those of the year 1903, and they are grouped by seasons and by good and bad days, the temperatures being summarized for differ- ent altitudes. It is to be noted that the as- cents were made at different morning hours, between nine and twelve, and, therefore, the mean obtained is not to be regarded as ac- curately representing the conditions during the twenty-four hours. The vertical tempera- ture gradients for the four seasons show a very slow decrease up to 2,000 meters in winter, and a rapid decrease in spring and summer. The average rate of temperature decrease for the year is about 1.3° per 100 meters near the surface, but decreases aloft, up to about 2,000 meters (0.9°), and then in- creases with altitude. The mean decrease of temperature for May, June and July between the surface and 500 meters is more rapid than the adiabatic rate of 1.8° in 100 meters. BAD WEATHER, GOOD ROADS AND FARMERS. Proressor A. P. Bricuam, in the Bulletin of the American Geographical Society for De- cember, emphasizes the need of good roads in the United States, and points out how great is the handicap of bad roads to farmers and to railroads. In this connection, the weather is an important factor, for when the roads are 76 SCIENCE. bad, the farmer is greatly restricted in the times when he can go to market. If high prices coincide with a period of wet weather and deep mud, the farmer may lose his oppor- tunity of getting his crops to market. In France, cold or stormy days are often used for hauling to market, but American farmers usually have to use for hauling the days which are the best for work on the farm. Railroad receipts often suffer a serious falling off when the weather is severe, and when the country roads are in such condition that farmers can not haul their produce to the train. MONTHLY WEATHER REVIEW. Tue Monthly Weather Review for Septem- ber, 1904 (dated November 19), contains the following articles of general interest: H. Elias, ‘A New Theory of Fog Formation’ (translated from the German); J. H. Spencer, ‘Three Notable Meteorological Exhibits at the World’s Fair’ (the U. S. Weather Bureau, the German and the Philippine Weather Bureau exhibits); and the following notes: ‘ Meteor- ology in Roumania’; ‘ Observations for Twelve Months in Lassa’ (data obtained by M. Tys- bikov, a Russian, who resided in Lassa from August 15, 1900, to August 22, 1901); ‘ Ob- servations at the Franco-Seandinayian Sta- tion for Aerial Soundings’ (from Comptes Rendus) ; ‘Wind Velocity and Ocean Waves’ (from a recent paper by Cornish). NO SECULAR CHANGE OF CLIMATE IN TRIPOLI. VICOMTE DE MATHUSIEULX, in an account of his expedition to Tripoli (Bull. Amer. Geogr. Soc., December, 1904), states it as his opinion that there is no reason for supposing any secular change of climate to have occurred in that region, although others have taken the opposite view. The Latin texts and monu- ments seem, to this writer, to establish the fact that so far as the atmosphere and soil are concerned, everything is just as it was in antiquity. The present condition of the country is ascribed to the idleness of the Arabs, who have allowed innumerable wells to become choked and the vegetation to perish. “Tn a country so little favored by nature, the first requisite is a diligent and hard-working (N.S. Vou. XXI. No. 524. population. The Romans took several cen- turies to make the land productive by dam- ming the ravines and sinking wells in the wady beds.” CLIMATIC CHANGE IN THE LAKE CHAD REGION. Tue evidence from the region between the Ubangi River and Lake Chad, studied by M. Aug. Chevalier in 1902-8, is, however, be- lieved to point towards a progressive desicca- tion there (La Geographie, May, 1904). M. Chevalier thinks it probable that a great river once flowed north across the Sahara to the Mediterranean, and that Lake Chad was mere- ly a back water. Vegetable and animal re- mains indicate an invasion of the Sudan by the Saharan climate, and Neolithic relics indi- cate the former presence of prosperous com- munities. The change is not a regularly progressive one, for Lake Chad sometimes spreads beyond its usual bed as a result of several years of heavy rainfall. Since 1897 the waters have continued to fall. After a drought in 1902, Lake Fittri dried up in the following year, and hippopotami which inhab- ited it went elsewhere. KITE METEOROLOGY OVER LAKE CONSTANCE. Dr. HerceEsett has contributed to a recent number of the Beitrage zur Physik der freien Atmosphire an account of the observations made by him with kites on the Lake of Con- stance, the flights being made from a motor- boat, loaned by Count Zeppelin, during the years 1900, 1902 and 1903. The observations show that inversions of temperature and of humidity frequently occur in the free air which are not exhibited by the observations made at mountain observatories. R. DEC. Warp. THE FIRST OBSERVATIONS WITH ‘BALLONS-SONDES’” IN AMERICA. As is known to many readers of ScIENCcE, there have been despatched in Europe fre- quently during the past ten years ballons- sondes, or small balloons carrying only instru- ments that record automatically the tempera- ture and pressure of the air, thus enabling the JANUARY 13, 190v.] temperatures to be determined at the succes- sive heights reached, the place and time at which the balloons fall indicating approxi- mately the direction and velocity of the upper currents. The ‘aeronautical concourse’ of the St. Louis Exposition afforded an opportunity to undertake these investigations in this coun- try. Accordingly, the work was taken up by Mr. A. Lawrence Rotch, director of the Blue Hill Observatory, in cooperation with Col. J. A. Ockerson, chief of the Department of Lib- eral Arts at the Exposition, and a series of very satisfactory experiments has just been completed. The balloons used in the experiments are the closed rubber balloons devised by Dr. Ass- mann, director of the Prussian Aeronautical Observatory. These balloons are inflated with about 100 cubic feet of hydrogen gas; they expand in rising until they burst, and then the attached parachute moderates the fall. In some eases two balloons, coupled tandem, were employed, and, as only one balloon bursts, the other is borne slowly to the ground and serves to attract attention. The instruments, which were furnished by M. Teisserene de Bort, of Paris, record the temperature and barometric pressure upon a smoked cylinder, turned by clockwork; and the lightest of them in its basket weighs about one and one half pounds. A notice attached to each requests the finder to pack the instrument carefully in a box and return either to St. Louis or to Blue Hill, with promise of a reward for the service. Owing to delays in obtaining the gas and apparatus, the experiments were not begun until the middle of September, during which month four ascensions took place. All of the balloons fell within a radius of fifteen miles, about fifty miles east of St. Louis. Twice the height of nine or ten miles was attained where a temperature of 68° F. below zero was recorded. These experiments were conducted by Mr. S. P. Fergusson, of the Blue Hill Ob- servatory staff. Another series of ten ascen- sions was executed by Mr. H. H. Clayton, meteorologist at the Blue Hill Observatory, during the last part of November and the first days of December, mostly after sunset, in order to avoid the possible effect of insolation. SCIENCE. Yi Fortunately, all these balloons were also re- covered, though the stronger upper air cur- rents carried them further from St. Louis, three of them traveling more than two hun- dred miles, and two, at least, with a speed exceeding one hundred miles an hour, the direction of every balloon being toward the easterly semi-circle. Ten of the fourteen as- censions furnished good records, and the re- duction of the later ones reveals lower tem- peratures than in September, for example, 72° below zero at the height of seven and three quarters miles on November 25, and 76° below at six and one quarter miles on the following day. The fact that all the balloons were recovered indicates the excellent topographical situation of St. Louis for despateching them, and Mr. Rotch expects to make another series of as- censions there this month, in order to obtain the temperatures of the upper air in mid- winter.

Fisher, assistant in the depart- ment of zoology, of Stanford University, de- livered a lecture entitled ‘ Bird-life on a Tropical Island of the Pacific. Dr. Orro Norpenskiotp lectured on his Antarctic exploration before the French Geo- graphical Society on December 16. Puans have been made to erect a memorial to Dr. Franz Riegel, professor of medicine at Giessen, who died last August. Nature states that it is proposed to estab- lish in the University of Liverpool a memorial to Mr. R. W. H. T. Hudson, late lecturer in mathematics, whose brilliant career was so tragically cut short at the end of last Sep- tember. The memorial will probably take the form of an annual prize in mathematics, to be awarded for distinction in geometry, the subject in Mr. Hudson’s work chiefly lay. which Dr. Bensamin West Frazier, professor of mineralogy and metallurgy at Lehigh Uni- versity since 1871, died as the result of a stroke of apoplexy on January 4, at the age of sixty-three years. Mr. C. C. Barrett, an English entomolo- gist, has died at the age of sixty-eight years. Sirk Lornuiran Betz, F.R.S., the author of works on metallurgy, died on December 20 at the age of eighty-eight years. Tue death is also announced of Professor Hermann Wilfarth, director of the Agricul- tural Experiment Station at Bernburg; and of M. Paul Tannery, author of works on the history of science. Foreign exchanges state that the Circolo Matematico di Palermo intends to offer an international prize for geometry at the fourth International Mathematical Congress, which will meet at Rome in 1908. The prize will consist of a small gold medal, to be ealled the Guiccia medal, after its founder, and of 3,000 franes, and will be given by preference, though not necessarily, to an essay which advances the knowledge of the theory of algebraical curves of space. The treatises may be written in Italian, French, German or English, and . uary 15. [N.S. Vou. XXI. No. 524. must be sent to the president of the Circolo Matematico before July 1, 1907. Tut New York Hvening Post states that in pursuance of the written agreement between Harvard and New York Universities, to carry on for ten years a biological station in the Bermuda Islands, a supervising committee has been completed by the acceptance of a third member of the committee, Hugo Baring, who was nominated by the Royal Society of Lon- don, which is a contributor to the enterprise through the Bermuda government. Harvard University is represented on the committee by Hon. Charles S. Fairchild, ex-secretary of the United States Treasury, and New York Uni- versity by Mr. William M. Kingsley, the treas- urer of the university. Mr. ANDREW CARNEGIE has given $263,000 to the Maryland Institute School of Art and Design, thus doubling the assets of the institu- tion. A new building will be erected to re- place the one destroyed in the Baltimore fire. It is also stated that Mr. Carnegie has inti- mated to officials of the Franklin Institute, of Philadelphia, that if they can secure the Franklin fund amounting to about $155,000, in the hands of the Board of City Trusts, he will add an equal sum to the amount. The Franklin fund, £1,000, was left to the City of Philadelphia by Dr. Benjamin Franklin in 1790, to be used in making loans to young married artificers under certain conditions. No loans under the conditions have been made for years. The money will be used for the erection of a new building. Tur Mexican Department of Agriculture is planning a series of meteorological stations to be conected by telegraph with the meteoro- logical observatory in Mexico City. Proressor Boycr, of Liverpool University, has proposed to the Liverpool Chamber of Commerce a scheme for the establishment of a commercial museum and bureau of scien- tific information.

KarusruHe has followed the example of Charlottenburg in establishing a tuberculosis museum. Arrangements are being made by which parties of working people will be en- abled to visit the museum from all parts of the country. WE learn from The British Medical Journal that a private citizen has placed in the hands of the government of the Grand Duchy of Baden a sum of $60,000 towards the founda- tion at Heidelberg of an institute for the study of cancer. The government has given a site for the purpose in the immediate neigh- borhood of the University Hospital, and has promised a grant for the maintenance of the institute. THe completed object-glass of eighteen inches clear aperture for the new observatory was formally delivered to the trustees of Am- herst College on December 31 by Mr. C. A. R. Lundin, the maker and optical expert, rep- resenting the firm of Alvan Clark and Sons. The objective was brought to Amherst by Pro- fessor Todd and deposited in the college vault for safe keeping till the mounting is ready to be erected in the spring. The flint and crown disks were made by Mantois, of Paris, and were pronounced by Alvan Clark the finest pair of disks ever received in his shops. The optical work upon them, figuring, correcting and polishing, during the past two years, fully maintains the highest standard of excellence set by this firm in the forty-inch Yerkes tele- scope, the thirty-six-inch Lick telescope, the thirty-inch Russian object-glass, the twenty- six-inch at Princeton, and numerous others. A Pactric Coast Biological Society was es- tablished at a meeting held in San Francisco on December 10. Its membership includes those who are carrying on research in zoology, paleontology, anatomy, physiology, psychology and botany. Meetings will be held four times a year. At the first meeting Dr. Jacques Loeb gave an address on heliotropism in ani- mals. Professor H. Heath, of the Stanford University department of zoology, was elected pres:dent, and Professor W. J. V. Osterhout, SCIENCE. ee) of the department of botany at the University of California, secretary-treasurer. A MATHEMATICAL section of the California Teachers’ Association was organized on De- cember 26, 1904, at San Jose. Professor G. A. Miller, Stanford University, was elected president, and Mr. J. F. Smith, Campbell High School, secretary. The main object of the association is to arouse more interest in mathematical pedagogy by means of separate meetings for the discussion of recent mathe- matical movements. Tue American Breeders’ Association will hold its annual meeting at Champaign, Illi- nois on February 1, 2 and 3. Special sessions will be devoted to the following subjects: specific methods of breeding corn, wheat, apples and other plants; methods of improving short horns, dairy cattle and other breeds of live stock, breeding disease-resisting plants, Mendel’s law, in-and-in breeding. Mr. Francis Darwin has written the follow- ing letter to the London Times: ‘Greek at Oxford, from a correspondent in 7'he Times of December 27 occurs the remark ‘It will be remembered also that Darwin regretted not having learnt Greek.’ I am at a loss to know on what authority this statement rests. If Darwin had any regrets on the subject of Greek it was when he found that in the two years intervening between leaving school and going up to Cambridge he had almost forgotten his classics, and had to begin again an uncongenial task in order to get a degree. Darwin says of his education at Shrewsbury School: “ Nothing could have been worse for the development of my mind than Dr. Butler’s school, as it was strictly classical, nothing else being taught, except a little ancient geography and history” (‘Life and Letters, I., 31). He was, in fact, a victim of that *‘ premature speciali- zation’ which is generally referred to in a some- what one-sided spirit, and from which the public schoolboy is not yet freed. If the name of Charles Darwin is to be brought into this controversy it must not be used for com- pulsory Greek, but against it. In an article on In 1867 he wrote to Farrar, ‘I am one of the root and branch men, and would leave classics to be learnt by those alone who have sufficient zeal and the high taste requisite for their appreciation’ (‘ More Letters of Charles Darwin,’ II., 441). 80U SCIENCE. Tur Biological Society of Washington offers for sale to the highest bidder, prior to January 15, 1905, its entire accumulation of exchange publications, consisting of about 1,500 serials or parts of serials, pamphlets and volumes on all branches of natural history. An opening bid of $25 is already in hand. The collection will be sold as a whole, and bids for parts can not be accepted. For information apply to the secretary, Wilfred H. Osgood, Department of Agriculture, Washington, D. C. Dr. Henry Fairritp Ossorn, Da Costa professor of zoology in Columbia University and curator in the American Museum of Nat- ural History, will deliver a series of lectures in February, at the Museum of Natural His- tory, on ‘The Evolution of the Horse.’ The lectures will be given under the auspices of Columbia University in cooperation with the museum, on the first three Mondays and the first three Wednesdays of the month. The stibjects are: ‘The Horse as an Animal Mech- anism,’ ‘The Horse in Relation of the Idea of Evolution, ‘The Fossil History of the Horse,’ especially in North America; ‘ The Fossil History of the Horse Continued,’ ‘ Ex- isting Races of Horses, Asses and Zebras,’ ‘Probable Origin of the Domesticated Breeds of Horses.’ A COLONIAL exposition will be held in Marseilles in 1906, for which preparations are being made with great energy. A site has been selected, and 1,500,000 franes has been voted by the department, city and chamber of commerce. The various French colonies have already appropriated 5,000,000 francs to meet their expenses in this exposition, and further financial aid is expected. Proressor Boycer, F.R.S., Dr. Arthur Evans and Dr. H. T. Clarke, who comprise the 13th expedition despatched by the Liverpool School of Tropical Medicine to West Africa for pur- poses of scientific research, sailed from the Mersey, on December 14. We learn from the London Times that on the day before they were entertained to a farewell luncheon by Sir Alfred L. Jones, and a numerous company of Liverpool commercial men were invited to meet them. Sir Alfred Jones in proposing [N.S. Vou. XXI. No. 524. ‘Success to the Expedition,’ said the Liverpool School had accomplished invaluable work in the direction of making the West Coast more healthful and habitable to white men and natives alike. Mr. James Boyle (American Consul) pointed out that Liverpool was rapidly forging to the front as a scientific center, and both London and Edinburgh would soon have to look to their laurels. Mr. Walter Long, M.P., said that Liverpool and the nation at large owed an incalculable debt to Professor Boyce. In the history of British colonization and territorial acquisition the most painful page was that in which one read of the death, not of men who had fallen sword in hand fighting under the flag of their country, but of those countless thousands whose lives had been sacrificed, as they now believed quite un- necessarily, to a deadly and unseen enemy, which had wrought such terrible ravages in the past, and which they had every reason to believe could now be vanquished. This was a great work, and must result in conquests as great and lasting as any that science had yet achieved. Professor Boyce, in responding, said that the feasibility of Ross’s views on this subject had now been proved up to the hilt. UNIVERSITY AND EDUCATIONAL NEWS. By the will of the late E. W. Codman of Boston and Nahant, Mass., an estate which it is said, may reach $1,000,000 will be equally divided between Harvard University and the Massachusetts General Hospital. Ir is said that the classes graduating from Princeton University from 1881 to 1902 have each pledged $10,000 for the erection of a new dormitory. Tue board of trustees of the University of North Carolina has authorized the organiza- tion of a School of Applied Science, consisting of the departments of mathematics and engi- neering, physics and electrical engineering, chemistry, geology and mining. Professor Gore is dean. Dr. H. Metprncer, professor of applied phys- ies at the technical institute at Karlsruhe, has retired from active service at the age of seventy-three years.

THE AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE. A TENTATIVE THEORY OF THERMO-ELEC-— TRIC ACTION.* Let the lines (1)—(1) and (2)-(2) in Fig. 1 be the lines representative respect- ively, of two metals M, and M, in the or- dinary thermo-electric diagram. We may, if we please, think of these metals as copper -and iron, respectively. The lowest horizon- tal line is the temperature coordinate and begins at the absolute zero. () B Ai 2) B ! S | | oS. O° Abs, > ae Jae Ie The diagram is so constructed that the area CC’I'IC is equal to the net thermo- electromotive force, EH, counterclockwise, in the circuit indicated by Fig. 2, in which the left-hand junction is kept at tempera- ture 7 and the right-hand junction at tem- perature 7’. We will suppose that EH’ is expressed in mechanical units, as the * Address of the vice-president and chairman of Section B—Physics, American Association for the Advancement of Science, Philadelphia, December, 1904.

Evi- dently, then, the area CC’l'IC, which rep- (2) Zi T Tat Fic. 2. resents H, represents also the mechanical equivalent of the net amount of heat con- sumed by unit quantity of electricity in one eyele. The arrow-points in Fig. 1 indicate merely the direction of the current result- ing from the net # of the cireuit. It is consistent with what precedes to consider the area BCC’B’B as representing that part of the total, or net, ZH which lies in the unequally heated M, between 7’ and T’, the area B’C’l'D’B’, as representing that part of HE which lies in the junction M,-M, at T’, ete.; and this interpretation is sometimes given as a mere statement of fact. In the course of this paper it will, I hope, be shown that another view of the matter is consistent with the known facts of the case. As this declaration puts me for the mo- ment into a somewhat heretical attitude, let me hasten to say that I hold as strongly as any one to the proposition that the area BCC'B’'B represents the amount of heat absorbed by unit quantity of electricity in going through the metal M, from the tem- perature 7 to the temperature 7”, that the area B’C'l'D'B’ represents the heat ab- sorbed by unit quantity of eleetricity in going from M, to M, at temperature 7”, ete. This proposition is familiar and needs no proof from me; but I wish to develop a little one aspect of it which is sometimes overlooked, an aspect which has a decided pedagogic value and which is at least sug- [N.S. Vox. XXI. No. 525. gestive of the line of thought I wish to fol- low later. As we have in Fig. 1 a diagram in which areas represent heat absorbed, and in which one of the coordinate axes represents tem- perature, the other axis must represent entropy. Let us, therefore, in order to conform to the common practise in the use of the temperature-entropy diagram, make the T axis vertical, and the entropy, or 8S, axis horizontal, thus getting as the equiva- lent of Fig. 1 the Fig. 3. Db’ D RIG. 3. 1 sok It is to be observed that Fig. 3 is the obverse of Fig. 1 so that the arrow points, without any relative change of position in going from one figure to the other, now lead clockwise around the area CC’l’IC. Any one who is familiar with the tem- perature-entropy diagram of the steam- boiler-engine cycle, as given and discussed by Ewing, will see at once interesting points of resemblance between Fig. 3 and that diagram. For example, the sloping line CC’, which indicates one phase of the Thomson effect, the absorption of heat by the electric current in passing through the metal M, from a point at temperature 7 to a point at the highest temperature, 7”, JANUARY 20, 1905.] is analogous to the sloping line which in the steam-boiler-engine diagram indicates the absorption of heat by the feed water. from the condenser in mixing with the hot water in the boiler. The slope of each line implies that the working agent, electricity in one ease and water in the other, takes in the particular quantity of heat repre- sented by the area under the line at a tem- perature below the highest of the cycle, and therefore, does not make the best possible thermodynamic use of the heat supplied and of the range of temperature available. Similarly the inclined line /’J, which indi- cates that heat is absorbed by the electric current in passing through the metal M,, from temperature 7” to the lower tempera- ture 7’, is analogous to the line of the steam eyele which indicates the recovery of heat from the cylinder wall during expansion after cut-off. Furthermore, the horizontal lines C’l’ and IC, indicating the absorption or emis- sion of heat by the electric current in pass- ing, without change of temperature, from one metal to the other, are analogous to those horizontal lines of the steam cycle which indicate absorption or emission of heat in the act of evaporation or of con- densation. To this analogy we shall pres- ently return. Let us for the moment occupy ourselves with a reexamination of the prevailing opinion as to the relation between the heat absorption or emission at the junction of two metals and the difference of potential, or the electromotive force, at that junction, that is, between the thermal aspect and the electrical aspect of the Peltier effect. We shall find the situation not quite so clear as it is often supposed to be. Maxwell* states that the amount of heat taken up or given out by unit quantity of electricity in going from one metal to an- other at any temperature is a measure of **Electricity and Magnetism,’ § 249. SCIENCE. 83 * ‘the electromotive contact force at the june- tion’; and he says that ‘this application * * * of the dynamical theory of heat to the determination of a local electromotive force’ is due to Sir Wm. Thomson.* He then goes on to declare that—‘‘The elec- tromotive force at the junction of two metals, as determined by this method, does not account for Volta’s electromotive force. * * * The latter is in general far greater than that of this article, and is sometimes’ of opposite sign,’’ ete. But it is a remarkable fact that Thom- son, years after he had pointed out the method which Maxwell approves for de- termining contact electromotive force, came out (in 1862) with a letter giving a ‘New Proof of Contact Electricity,’ his famous ‘divided ring’ experiment, in which letter he says ‘‘For nearly two years I have felt quite sure that the proper explanation of voltaic action in the common voltaic ar- rangement is very nearly Volta’s,’’ ete. I do not feel called upon to take up the cudgels for Thomson or for Volta. The point of immediate interest is that Thom- son, after proposing the thermodynamic method of determining contact electro- motive force, found it possible to hold a view contradictory to the soundness of this method. This fact may give the rest of us courage to question the finality even of Maxwell’s opinion as to the relation be- tween electromotive force and heat in the Peltier effect. I believe, too, that Poin- earé, in article 292 of his ‘Thermodynam- ique,’ holds that the opinion supported by Maxwell may be wrong. Let us see what we can do with the question thus raised. By difference of potential, D.., between two points I shall mean the net amount of work which must be done because of the attractions and repulsions of electric charges (to use the convenient terms of * Proc. Roy. Soc. Edin., Dec. 15, 1851; Trans. Roy. Soc. Bdin., 1854. 84 SCIENCE. action at a distance) in carrying unit quantity of positive electricity from point 1 to point 2. By electromotive force, Ey, along a given path from the point 1 to the point 2, I shall mean Fy2 = Day + t1.2Ri2, where 7,, is the current from (1) to (2) and R,. is the resistance of the chosen path from (1) to (2). If either 7 or R is zero, Fi2= Daa, which is practically the case when we have a battery in open cireuit, (1) being one terminal and (2) the other, or when we have under consideration two points on opposite sides of a junction of two metals, but exceedingly near together, even if a current is flowing from one to the other. We have already, looking at Fig. 3, com- pared the passage of electricity from metal 1 to metal 2 to the evaporation of water in a boiler. Now in this evaporation work of two kinds is done upon the water, in- ternal work and external work. The move- ment of electricity across a junction against a difference of potential corresponds to the external work of evaporation. Is there accompanying this movement anything cor- responding to the internal work of evapora- tion? If so, the heat absorbed by the elec- tricity in the movement may be as bad a measure for the difference of potential at the junction as the latent heat of evapora- tion would be for the external work of evaporation. It is not absurd to imagine that there may be some change of state of electricity besides change of potential. It is possible that we should take account of something like an attraction between electricity and the metals with which it is associated. Helmholtz imagined such an attraction in order to explain the action of a galvanic cell, Indeed, we are familiar with the idea [N.S. Vou. AXI. No. 525. that attraction or repulsion exerted on the electric charge which ordinary matter may bear is communicated to the matter itself. When the charge on a pith ball is drawn this way or that, it carries the pith ball along withit. To be sure, this phenomenon and others like it may not indicate any fundamental attraction between ordinary matter and electricity. Perhaps they can all be explained by stresses in the dielectric surrounding or penetrating the ordinary matter; but whatever the true agencies may be, they at least simulate attraction or some physical tie between ordinary mat- ter and electricity. We may, therefore, feel free to make speculative use of such attraction. Our problem is to find, if we can, by use of any reasonable hypothesis, an explana- tion of the way in which heat drives an electric current around the cireuit of dis- similar metals unequally heated. There are two types of mechanical cir- cuits or cycles operated by heat with which we are very familiar, the steam-boiler- engine cycle, in which the circulation may be practically in a horizontal plane, and various convection cycles, commonly used for heating and ventilation, which may be in vertical planes. In the horizontal cycle we must have valves. Circulation is se- cured by heating or cooling a fluid which is free to expand or to contract on one side, but not on the other side, the valves being so contrived as to give the necessary free- dom and the necessary restriction. In the convection eyele we do not necessarily make use of valves. If the heating and cooling are effected at the right parts of the cir- cuit, gravity supplies the differential force necessary to maintain circulation. How can the metals of our thermo-elec- tric cireuit take the function of valves or the function of gravitation and so deter- mine the flow of electricity at the expense of heat energy? JANUARY 20, 1905.] Let us consider first the case of a thermo- electric couple in which neither metal has any Thomson effect, but in which there is a tendency of positive electricity from (1) to (2) at each junction. The thermo-elec- tric force of such a circuit can be accounted for by assuming that metal 2 attracts posi- tive electricity more and negative elec- ‘tricity less than metal 1, and that both these differential attractions increase or . decrease with change of temperature of the electricity. At first glance one is likely to think that the differential forces here imagined must increase with rise of temperature, as it may at first seem that the forces at the hot june- tion must prevail over the opposing forces at the cold junction. But this need not be. The action must be such as to take in heat at the hot junction and to give out heat at the cold junction; but this condi- — tion is perfectly consistent with the pre- vailing of the attractive forces at the cold junction. For, consider the analogous ease of cir- culation of water in a pipe circuit made up of two verticals and two horizontals (see Fig. 5). If heat is applied at the proper part of one vertical and if heat is taken away from the proper part of the other vertical, the water will ascend against the force of gravity at the heated place and descend under the pull of gravity at the eooled place. That is, the attractive force, upon the differential action of which the circulation depends, prevails at the place where heat is taken out from the system. Another analogous case is that of two galvanic cells of precisely the same kind, one cold and the other warm, set to work in opposition to each other. If the cells are such that each would grow warm (aside from the development of resistance heat within its parts) by its own direct action, the cooler cell will prevail, and vice versa. SCIENCE. 85 So, if the spontaneous action at each junction of our two metals, if each junc- tion could have its own way, would be such as to generate heat at the junction, the cooler junction will prevail when the two are opposed, and vice versa. Now we have rather more reason for expecting, in a given untried case, that the - free action of attractive forces will generate heat than we have for expecting that it will absorb heat. Consider, for example, the heat freed as the result of molecular attractions in the condensation of a vapor. Accordingly, if we are to account for a thermo-electrie current, in such a combina- tion of metals as we have imagined, by attraction of ordinary matter for elec- tricity, this attraction varying with the temperature of the electricity, we are nat- urally led to the opinion that the colder junction prevails. The assumption of such an attraction as we have here imagined, with its dependence on the temperature of the electricity and its independence of the temperature of the metal, except as the temperature of the metal determines that of the electricity within it, is much less violent than it at first appears. If there is such a phenom- enon as the expansion of electricity, that is, a diminution of general volume density of electricity, with rise of temperature of the metal containing it, corresponding to the expansion of air or water in the heated part of a convection circuit, this is enough to give just the temperature relation re- quired. For, the lessened volume density of the electricity at the hot junction of the two metals would imply a diminished tend- ency of the electricity to pass over to the more strongly attracting metal at that junction; but just as there is no tendency of water to flow by gravitation along an unequally heated pipe, if this pipe is hori- zontal, so there would be no tendeney for electricity to flow along an unequally heat- 86 SCIENCE. ed homogeneous metal bar, unless the hot parts of this bar attracted a given quantity of electricity more or less strongly than the vold parts. The two metals in which we have stipulated that there shall be no Thomson effect correspond in our thermo- electric circuit to the horizontal pipes of our imagined convection system; and for. the comparison which we are here making it-is well to go back to the usual disposition . of the thermo-electrie diagram, in which unequally heated metals having no Thom- son effect are represented by horizontal lines. Let us now consider a case in which the Thomson effect does play a part, such a ease as that illustrated by Figs. 1 and 3. We ean, apparently, account for the Thom- son effect in any metal by assuming that this metal has a greater attraction for elec- tricity of one sign than for electricity of the opposite sign, and that the difference of these attractions is a function of the temperature of the metal. With this con- «lition the electricity of one sign at any part of a homogeneous but unequally heat- ed metal bar will be subject to a net attrac- ticn, exerted by the metal, toward a place cf higher temperature or toward one of lower temperature, according as the attrac- tion between the metal and this kind of electricity increases or decreases with rise of temperature of the metal; and the other kind of electricity will be subject to a dif- ferent, greater or less, net attraction from the metal; so that a difference of potential would be set up between the hot and cold part of the bar, if the bar were left to itself. If we take the view that the electromotive forces which prevail are those at places where heat is given out, we shall in Fig. 3 have the local electromotive forec, due to ‘the attraction between metal and_ elee- ‘tricity, opposite at every place to the elee- tromotive force commonly supposed to re- [N.S. Vou. XXI. No. 525. side at that place; so that the unequally heated metals and the hot junction will still conspire against the cold junction; but, as the direction of the current is known by experiment to be that which is indicated by the arrow points in Fig. 3, we must in this case suppose that the cold junction prevails over the opposing com- bination. Let us now consider the magnitude of the local electromotive forces. In any case the net electromotive force of the whole circuit is expressed, as we agreed at the beginning, by the area CC’l'IC of Fig. 1 or Fig. 3. But knowledge of the net elec- tromotive force of the circuit tells us little or nothing of the magnitude of the indi- vidual four electromotive forces of the cir- euit. Ordinary doctrine represents these by the areas, already mentioned, under the lines CC’, C'l’, ete., in Fig. 3, down to the line of absolute zero of temperature, but as we now undertake to have the electro- motive force at the cold junction prevail over the other three, it is evident that we must look for other areas on the thermo- electric diagram to represent these local forces. In this case we find such areas above the lines CC’, C’'l’, ete., in Fig. 3, or in Fig. 4, which we will now use in place JANUARY 20, 1963.] of Fig. 3. Thus the area Cbb’C’C, ter- minated above by the temperature lne 7, characteristic of metal 1, may represent the thermo-electromotive force directed from C’ to C in the unequally heated (1). Similarly the area I’d’dII', terminated above by the temperature line 7.,, charac- teristic of metal 2, may represent the thermo-electromotive force directed from I to I’ in the unequally heated (2).* The area 0’b'efd'l'C’, terminated above by the broken line b’efd’, depending on both 7, and T,, may represent the thermo-electromotive force directed from I’ to C’ at the hot junc- tion. Finally the area Cbb’efd’dlC, term- inated above the broken line bb’efd’d, de- pending on both 7, and 7.,, may represent the thermo-electromotive force directed from I to C at the cold junction. This last, larger than the sum of the others, which oppose it, would be the prevailing electro- motive foree. The net electromotive force of the cireuit would be, as in Fig. 3, repre- sented by the area CC’I’IC, and the cur- rent would run, as before, clockwise with respect to the boundary of this area. We have apparently succeeded in ac- counting for the circulation of the elec- tricity by means of differential attractions conditioned by differences of temperature and in showing that the local electromotive forces of the thermo-electrie circuit may be opposite in direction to those which are commonly supposed to exist. But we have as yet given no conclusive reason why heat should go in at one part and out at the other, and we have not yet made any at- tempt to show how heat is used up in the circuit. Our explanation, so far as it has *T, is apparently the temperature at which the differential attraction of M, for the two kinds of electricity becomes zero. A like explanation holds fom: [The sloping lines might curve so as to strike the lines 7, and T., respectively, at any angle. | SCIENCE. 87 now gone, utilizes difference of tempera- ture but does not utilize heat. If we return to the consideration of our analogical convection system, we see that, if we were to put in heat at any point p only and take out heat at the point p’ only, these two points being on the same level, there would be no continued circulation, as we should presently have the fluid at a uniform temperature all the way over from Oo i } p to p’ and at a uniform, though different, temperature all the way under from p’ to p. To maintain circulation we must have the point p, at which heat enters, at a lower level, and therefore at a higher pressure, than the level and the pressure of the point p’, at which heat comes out. The work and the absorption of heat at expansion under high pressure would be greater than the return work and the emission of heat at the lower pressure, and the difference between the inflow and the outflow of heat would be utilized in maintaining tion against some resistance. Do we naturally find anything in our thermo-electrie circuit corresponding to this heat differential ? We have already assumed that the elec- tricity within each metal acts like an ex- pansible fluid, and it is natural to assume that the rise of temperature which causes the expansion of the electricity absorbs heat. That is, we naturally assume next that there is a real thermal capacity of eircula- 88 SCIENCE. electricity, or of the corpuscles moving with it, which would come to the same thing. Moreover, we can hardly avoid supposing that the attraction which we have assumed to exist between metal and electricity holds the electricity within the metal in a state of pressure; and accord- ingly we must recognize in the thermal capacity of the electricity a part accom- plished against this pressure in the expan- sion which accompanies rise of tempera- ture. Returning, with these additional ideas, to the examination of a thermo-electric cir- euit showing no Thomson effect, we find that we must in such a ease suppose that in each metal the heat absorbed by the current of electricity, positive or negative, which is flowing from cold to warm within that metal is balanced by the heat given out by the current of opposite sign, nega- tive or positive, which is flowing in equal strength from hot to cold within the same metal. But at the junctions the case is different. At the junction which is the prevailing’ one, across which each kind of electricity flows from the metal by which its kind is attracted less to the metal by which its kind is attracted more, that is, from a place where the pressure caused by the attraction is less to a place where the pres- sure caused by attraction is more, each kind of electricity will, without change of tem- perature, suffer contraction of volume in the transition, and evolution of heat will result. On the other hand, at the other junction, where each kind of electricity moves, without change of temperature, from a place of high attractive pressure to a place of low attractive pressure, each kind will expand in the transit, and ab- sorption of heat will accompany this ex- pansion. Thermodynamic considerations show us that in such a case as that which we are LN.S. Vou. XXI. No. 525. considering, in which there is no Thomson effect, heat must be taken in at the hot junction and heat must be given out at the cold junction. Hence our theory, with its later assumptions, assumptions suggest- ed, as others have been, by reflection on the manner and reason of the working of an ordinary convection cycle, has led us clearly to the conclusion that the cold june- tion should be, in the case considered, the prevailing junction. But thermodynamic considerations go further. They require that the amount of heat, Q’, taken in at the hot junction at temperature 7’, must bear to the heat, QY, given out at the cold junc- tion at temperature 7, such a relation that Can we without a straining extension of our assumptions meet this condition? Ap- parently we can do so by supposing that electricity in its state of compression with- in each metal obeys the law of a perfect gas. At the hot junction we have the posi- tive electricity going, at constant tempera- ture 7’, from the attractive pressure p to the attractive pressure p — dp, with con- sequent expansion, work of expansion, W’, and absorption of heat equivalent to this amount of work. At the cold junction we have the positive electricity going, at con- stant temperature 7, from the attractive pressure p — dp to the attractive pressure p, with consequent compression, work of compression, W, and evolution of heat equivalent to this amount of work. From the gas law, pv = KT, we have, when T is constant, padv = — dp = — This gives us, since p and dp are the same at the hot junction as at the cold junction, W’:W vs: pdv’ : pdo:: Ws 7: And so ORNONI Ts he JANUARY 20, 1905.] The production of absorption of heat within a single unequally heated metal, the calorimetric aspect of the Thomson effect, is, apparently, easily accounted for without additional assumptions. Thus, according to the theory already stated, the line CC’ in Fig. 4 represents a case in which the attractive pressure of the positive elec- tricity is greater at the cold end than at the warm end, while the attractive pres- sure of the negative electricity is greater at the warm end than at the cold end, of metal 1. According, positive electricity moving from the eold end to the warm end of this metal will expand more, and there- fore absorb more heat, than the mere rise of temperature requires, while the negative electricity in moving from hot to cold with- in the same metal will contract less, and therefore give out less heat, than the mere fall of temperature requires. That is, to use the conventional mode of expression, the current absorbs heat where it flows from cold to hot in metal 1. For the line II’ and the metal 2 the case is wice versa. The conception of electricity, each kind of electricity, as acting within a metal like a perfect gas seems very revolutionary to one who has been strongly impressed by Maxwell’s discussion of the analogy which the behavior of electricity in Faraday’s ‘ice-pail’ experiment presents to the be- havior of an ‘incompressible fluid,’ though Maxwell in pointing out this analogy warns us against being too much influenced by it. The ice-pail experiment, however, as I understand it, proves merely the difficulty in putting an appreciable excess of either kind of electricity into a given space, a difficulty which still exists after all the assumptions of this paper are made. Con- sider, for example, the difficulty of putting any considerable excess of positive or of negative ions into an electrolyte. Indeed, the idea of the electric current within a solid as consisting of two oppositely mov- SCIENCE. 89 ing perfect gases is so like the familiar and commonly accepted idea of the current in an electrolyte, where we apparently have two oppositely moving bodies of ions, each body obeying the gas law in its osmotic pressure, that, instead of being troubled by the heretical character of this view of the current in a solid, I am somewhat con- cerned lest I am failing to give due credit to some one who has already proposed it. Of course, Drude in his electron theory does apply the gas laws in some particulars to the electrons within metals, and I can not be sure that he has not anticipated me in much that is given in this paper, though I did not, so far as I am aware, get from him any of the main features of the theory here proposed. The question naturally arises, Why not determine the direction and magnitude of the local electromotive forces of the thermo- electric circuit, and so get a decisive trial of the case between the ordinary and the proposed view of thermo-electrie action? The reply is that physicists have been try- ing for more than a hundred years to get a satisfactory determination of a single one of these local forces, the one measured by the true contact difference of potential between any two metals, and have, appa- rently, not yet succeeded in the attempt. It is the old question of the Volta effect. Some months ago I was of the opinion that Mr. John Brown, F.R.S., of Belfast, had found a way of getting rid of the dis- turbing effect of the medium surrounding the two metals, zine and copper in his ease, by heating them for several hours in a cer- tain kind of oil. Considerable recent ex- perience with various kinds of oil at the Harvard Physical Laboratory has led me quite unwillingly to the conclusion that the kind of treatment to which Mr. Brown subjects his metal plates may substitute for the disturbing surface condition ac- quired in air an equally baffling surface 90 SCIENCE. condition produced by the action of the oil. An attempt to measure directly the dif- ference of potential between the two ends of an isolated unequally heated bar of metal would, apparently, encounter ob- stacles quite as great as those which have thus far proven unsurmountable in the ease of attempts to measure directly the eontact difference of potential between metals. The outlook is, therefore, not bright for any immediate and final answer, on experimental grounds, to this question of the direction and magnitude of the local electromotive forces with which we have been dealing. I wish to add one afterthought. If elec- tricity flows like a perfect gas through a homogeneous solid conductor of uniform cross-section, its velocity at any given cross- section of the conductor must be, approxi- mately at least, proportional to the abso- lute temperature of this cross-section. Now the ordinary law of resistance in the case of a fluid moving through small passages is this: Resistance is proportional to the velocity. Accordingly, we are led to the conclusion that the resistance encountered by our electric stream should be propor- tional to its velocity, that is, other things being equal, proportional to the absolute temperature at the part of the conductor considered. Now we know that in pure metals this is the general law of resistance, and the fact that this law finds an explana- tion in a conception of the electric current formed without any reference to electrical resistance adds considerable weight to the argument in favor of that conception.

THE ALAMOGORDO DESERT.* THE desert of southern New Mexico lies immediately west of the Alamogordo * Address by the vice-president and chairman of Section G for 1904. Philadelphia, Pa. [N.S. Vou. XXI. No. 525. 106th meridian, west, and approximately between thirty-two and thirty-four, north. It is bounded on the north by the Oseuro range of mountains, on the east by the Sacramentos, on the south by the Jarillas and the Organ mountains, on the west by the San Andreas. As here defined, there- fore, the desert is of comparatively limited area, one hundred or one hundred and twenty-five miles from north to south, and perhaps thirty-five to fifty from east to west; a very convenient little desert, easily manageable, one might suppose, for any naturalist, who, with inborn love of ad- venture, starts out in search of the wilder- ness to find scenes and pastures new. A year ago in this presence, it may be recalled, the present speaker, by aid of photographie illustrations, attempted to sketch the relations obtaining, as would appear, between the geology of the desert and its flora; in the present paper it is intended briefly to resume the earlier argu- ment with such added reflections as may be suggested by present conditions and by recent renewed acquaintance with the prob- lem. The desert of Alamogordo or Tularosa is a great plain, not unmarked, however, by singular topographic inequalities later on to be deseribed. Only the most casual geologic examination is sufficient to show that the plain floor corresponds strati- graphically with the beds in some places exposed at or near the tops of the sur- rounding mountains, in any case far up their flanks. On the east especially lime- stones of carboniferous age rise sheer some 1,000 feet or more straight up from the desert floor, and are again capped by other strata only at length, perhaps 1,000 feet higher, surmounted by materials corre- spondent with those in the level of the plain. On the west the same thing is true; but more emphasized still is the difference in JANUARY 20, 1905.] level between segments of corresponding strata. Here the weird Organ mountains break the horizon by upthrust spires and pinnacles of granite which to some early voyageur crossing these dusty plains sug- gested the pipes and architecture of some far-off organ, and the mountains were so named; but upturned granite means that the sedimentary rocks are here further up- lifted still than on the eastern side, so that we quickly find ourselves in presence of vast parallel faults and our desert hes thus between their giant walls. It is as if half the region between this city and New York should suddenly sink two or three thou- sand feet, or what is the same thing, it is as if the several thousand feet of difference in level were brought about by the depression of the included area, and the simultaneous elevation of the sides. At any rate, the desert plain of the Alamogordo or Tularosa sands is simply the upper surface of a migantic block of the earth’s crust that sank some time subsequent to the deposi- tion of the Jura-Trias and the earlier eretaceous strata of this western world. These strata include, as we know, the famous ‘red beds’ which tinge the moun- tains of half the continent, the red beds with all their gypsums, marls and salts of every description. Accordingly, as a re- sult of this faulting, our desert has for its foundation everywhere great fields of gyp- sum, often for long distances wide-exposed, sometimes thinly veiled by loosened sand, sometimes deep buried by vast deposits of wine-red marls and clays, or covered anon by the products of erosion, whether by water or by wind. The waters from the mountain snows have brought their débris; the winds of the desert have come with their burden, but nowhere has such trans- portation traversed the desert borders, at least in recent times; there are to-day no excurrent nor percurrent streams; the SCIENCE. ot winds die along the mountain walls and the waters sink in the desiccated sands, But this is not all. This great sunken block of earth’s crust seems itself to have been cracked again and again; there are secondary faults, and along the line of one of these thinner or weaker places the sub- terranean energies of the world have some time found emergence. Floods of lava welled up in the midst of the desert, and fountains of fire streamed along the eround, following existent topography for miles and miles, now narrowing to dimen- sions measured by rods between low ranges of hills, now widening for miles across the broader valleys, only to lie at last a vast field of blackened cinder, slowly disin- tegrated by the desert storms. This is one of the most peculiar topographic features of the whole desert. As things terrestrial go, this is a recent phenomenon. The age of the lava may be measured by centuries, a few thousand years, it would seem, at most. The surface over which it poured was a friable, marly soil. As the floods cooled, the mass cracked and gaped in every direction. Rains descending upon the sur- face sank to the ground below and shaped for themselves channels. The lava so un- dermined has fallen into a tumbled ruin of weirdness and confusion, indescribable, impassable. The lava constitutes one of the features of this remarkable desert; there is yet an- other. Along the western border, partly uncovered by erosion, partly by the west- ern winds, great bodies of gypsum lie ex- posed. As this slowly disintegrates the wind gathers the particles set free and bears them eastward, the famous white sands, covering township after township with drifted mineral white as snow. Vast windrows shifting slowly with every storm, and forever reinforced by the unceasing contributions of the west, mark the land- scape over several hundred square miles, 92 SCIENCE. unique, intact, forever changing, yet the same forever. Added to these peculiar and special topo- graphic details of this surprising desert we have, of course, those less noteworthy, the common every-day features of desert make-up: we have mountain slope, rocky fields and hillsides, eroded valleys, marshy sinks, where lose themselves the vanishing torrential streams; wide plains of marly clay, belts of sand-dunes, red sands, yellow sands, also shifting and moving, but, better subservient to the vegetation of the region, these present simply vast fields of low hills or hummocks ten to twenty feet in height, separated on every side by tortuous valleys, winding in labyrinthine fashion, wind-swept, hard and bare. One other topographie feature must yet be added to complete our picture. The forces of erosion even along the mountain walls have kept pace fairly well, at least, with the changes in level. Great canons break back even through the hard, eneri- nitic limestones, dividing again and again where the waters have carved the rugged pathway by which the explorer may reach the mountain summit. The result of this erosion forms a wide talus around the desert, spreading great fan-shaped deposits at the mouth of the cafon, where immense blocks and boulders choke the exit, suc- ceeded by ever smaller rocks and pebbles farther out, until at length only the finest silt is swept along from the widened mar- gin far across the almost perfectly level plain. Now it is evidently needless to say to every wisest man in an ecologically minded such as this, that every one of these peculiar topographic features, whether special or not, will display its own peculiar flora. True, this is not always the ease; this desert must be studied in its entirety, and it will require months of patient research to even sketch its far- audience [a.S. Vor. XXI. No. 525. reaching problems. As a whole the fiora may be said to be that of our western arid regions generally, and yet, after all, it is not just like that of any other region, north, south, east or west; not that it has peculiar species, perhaps, but that it has its own particular groups of species. Two factors, and two alone, as it seems to me, determine the phytology of this desert; the one, difference in the constitution of the soil, referable to its geologic history; the other difference in level, referable to the same initiative. Thus there is a pecul- iar flora on the sands whether white or red; another on the silted plains less liable to transportation by the wind; another where the salts emerge, whether in briny springs and fountains or as_crystals whit- ening the surface of the ground; another for the mountain shelves; and still another for their far-off summits. The El Paso Northeastern Railway passes the desert on its eastern side. There are two stations on the line where for several miles in every direction the surface is a red-brown sand. One of these stations has been by the railroad people appropriately named Desert, the other is Esecondida. The level of the two stations is the same, 4,000 feet, and the flora is identical, although the points are thirty miles apart. Each, however, is by itself unique and entirely separate from the other. The dominant species is Yucca radiosa, so much so that these points are called the yucea desert. Of course, the almost ubiquitous mesquite is there and Atriplex canescens and Arte- misia —— sp.? There are other species, to be sure, such as forms of Chrysothamnus and Ephedra, but the plants first named give to the plain its character as far as vegetation goes, and in topography as well; they not only thrive here and come to abundant flower and fruit, but they hold these peculiar sands otherwise driven about the world by desert winds. -with comparative ease. ---UARY 20, 1905.] Now it is a remarkable fact that the white sands, thirty or forty miles off to the northeast, exhibit an almost identical flora. The student hastens across the intervening desert to meet that shining wall, expecting to find all things new; but, behald, the white sands are sands first of all rather than anything else. Whatever their chem- istry, and they have their peculiar prob- lem for the chemist, only a vegetation that can endure a moving, shifting terrene can flourish here. The white sands form, ac- cordingly, part of the yueca desert. Their relation to vegetation is almost purely physical, but they exhibit some peculiar- ities. They are gypsum, as everybody knows,* but while they move as other sands, they must be compared with wet sands; the vast drifts, thirty to fifty feet in height, are moist often to within a few inches of the surface, and are so compactly driven that one may walk upon the solid surface A white wall like to the appearance of marble is moving slowly eastward, whelming all vegetation as it goes, some of which, able to grow through the encroaching mass, persists, so that all the plants now appearing on the surface, so far as examined, are anchored by lengthened stems or roots to the under- lying older soil. The same yueea that appears at Escondida here emerges some- times by green tips from a snow-white drift twenty feet in height, or anon, seems to crown triumphantly some lower mound. The mesquite holds on, in some places a desperate fight, and certain species ef Rhus —R. aromatica and R. trilobata, perhaps— maintain a perilous existence out over the *The following analysis of this material has been kindly furnished me by Dr. L.

THE NATIONAL BUREAU OF STANDARDS AND ITS RELATION TO SCIENTIFIC AND TECHNICAL LABORATORIES.* THE dedication of a large and well-ap- pointed building to be devoted exclusively to instruction and research in physics is a notable event in the history of a college. In this instance it is the realization of a hope long cherished by many, and by none more than by the present speaker. That so splendid a building has been deemed neces- sary for, the work to be done in physics suggests two things. First, the high stand- ard which Wesleyan is setting for herself in this as in other departments of work, and, second, the rapid development which has oceurred in recent years in physics, rendering imperative an equipment for ex- perimental work of an entirely different order of magnitude from that thought suf- ficient a generation ago. So great has been the demand for the best instruments and standards to be used in experimental work, both in pure and in applied physies, that the government has been led to establish at Washington a national laboratory, one of whose functions is to cooperate with scien- tifie and technical institutions and manu- facturers in the work of improving instru- ments and standards and developing meth- ods of measurement. It, therefore, seems not inappropriate that something be said on this oceasion concerning this work of the national government, so recently in- * An address delivered at the opening of the John Bell Scott Memorial Laboratory of Physical Science, at Wesleyan University, Middletown, Conn., December 7, 1904. 162 augurated as not to be generally known. The bureau of standards was established by act of congress in response to a de- mand for such an institution on the part of many scientists, engineers, manufac- turers and representatives of the national government. The high order of accu- racy required in modern engineering prac- tise and in scientific research made it more than ever. necessary that manufacturers of scientific and engineering instruments should possess correct standards of length, mass and volume, as well as electrical, op- tical and thermometrie standards, and be able to have them reverified from time to time. It was also important that any one engaged in scientific or engineering work could have his instruments and standards tested whenever, necessary. The office of weights and measures, at Washington, had been equipped to do some of the work re- quired in the verification of length, mass and volume for many years, but it was uecessary to send electrical standards, thermometers and pyrometers and many other kinds of apparatus to Europe to be tested when results of the highest accuracy were desired. As this was both expensive and time consuming the consequence was that only infrequently were these more ac- curate tests obtained. The United States held a creditable position among the na- tions of the earth in physical science, and had some of the best physical laboratories in the world; it was leading the world in the manufacture of electrical machinery and some kinds of electrical instruments. To’ be obliged to ask the German imperial or other foreign laboratories to do our testing for us, because we lacked a well- equipped national laboratory for doing such work, was clearly a situation that ought to be corrected, and congress acted promptly when the importance of the matter was brought to its attention. Appropriations were made for laboratory buildings and SCIENCE. [N.S. Vou. XXI. No. 527. equipment and for a director and a small scientific staff, and the bureau began its work July 1, 1901. President McKinley appointed as director Professor S. W. Stratton, of Chicago University, to whom more than to any one else is due the credit for, the establishment and the success of the bureau. A careful study of the Physi- kalisch Technische Reichsanstalt and of other European laboratories was made in connection with the designing of the labo- ratory buildings and the selection of the equipment, and many valuable suggestions were derived therefrom. The laboratories have, however, been constructed after Am- erican rather than European models, al- though in their equipment it has been found necessary to draw very heavily upon European instrument makers. The bureau began its work in temporary quarters and has been developing methods, building and acquiring apparatus and do- ing testing for the government and the public while the laboratory buildings have been under construction. The larger of the two buildings was only recently com- pleted and the bureau is just now moving into it, the first building having been occu- pied nearly a year ago. We now find our- selves, about three and a half years from the organization of the bureau, in posses- sion of buildings and equipment costing about $600,000, with a personnel carefully selected through the civil service and num- bering altogether seventy-one, maintained by annual appropriations amounting to nearly $200,000, and, judged by the magni- tude and importance of the output of test- ing and investigation, ranking second only to the great German Reichsanstalt among the government laboratories of the world doing this kind of work. After this brief epitome of the history of the bureau let me state more particu- larly something of its work and of its rela- FEBRUARY 3, 1905.] tion to the scientific and technical labora- tories of the country. The work of the bureau may be briefly specified under three separate heads as follows: 1. To acquire and preserve standards of measure and to certify copies of the same, and to test and investigate measuring in- struments and to determine the properties of materials. 2. To conduct researches and to investi- gate and develop methods of measurement ; to improve instruments and apparatus for physical measurements and to devise new apparatus, especially for use in testing and in precise measurements. 3. To distribute information regarding instruments and standards to manufactur- ers, state and city sealers of weights and measures, scientific and technical labora- tories, and to any and every one applying for such information. These three functions of the bureau are closely interdependent. To acquire a standard in some cases involves an elab- orate investigation and the independent determination of the value of the stand- ard; and to preserve it may involve subse- quent redeterminations of its value to ascertain whether any change has occurred. A new kind of test often involves the in- vestigation of methods of measurement, or the determination of new standards or the construction of a new instrument. Thus research and testing are intimately con- nected in most of the work of the bureau. The distribution of information, the third function of the bureau, is accom- plished through correspondence and the cireulars and bulletins issued by the bu- reau, and also by the personal visits of people seeking such information. The three fundamental standards of measure are those of length, mass and time. The oldest of these is the unit of time, the second. This ancient unit has successfully SCIENCE. 163 withstood every attempt to replace it by a decimal submultiple of the day. The earth itself is our fundamental timepiece, every revolution upon its axis counting off 86,400 sidereal seconds, from which we immedi- ately derive our standard second. No clock is so perfect a timepiece as the earth and all the standard clocks in the world are corrected by it. What the astronomer does in determining the time by astro- nomical observations, is to read off the time of day or night by means of a tele- scope on the starry face of the celestial clock. The telescope corresponds to the hour hand of a 24-hour dial (there is no minute hand), and the stars mark the sub- divisions of the dial. The best made clocks of human invention go fast or slow by at least some fraction of a second each day, but there is no proof to show that the ter- restrial clock deviates by so much in a thousand years. Thus the unit of time is a natural unit, easily obtained direct from nature and universally employed the world over. The Bureau of Standards does not in- tend to make independent time observa- tions, but will correct its standard clocks from the observations made at the neigh- boring Naval Observatory. The unit of length has a very different history. The foot has been the most wide- ly used measure of length, both in ancient and in modern times. It was derived, as the name suggests, from the length of the human foot and is thus a natural unit like the second; but, owing to the multiplicity of human feet and their varying dimen- sions, this unit has varied greatly in differ- ent countries and in different ages, its leneth ranging all the way from the an- cient Welsh foot of nine inches to the Pied- mont foot of twenty inches. In modern times it has varied from the Spanish foot of less than eleven inches to the Venice foot of over thirteen inches, almost every coun- 164 try using a foot of different length. The confusion resulting from this lack of uni- formity prompted the French in 1799 to adopt a new unit of length, and remember- ing how surely and elegantly the unit of time is fixed by the rotation of the earth, they sought to make the meter, the new standard of length, permanent and inflex- ible by basing it upon the dimensions of the earth. The meter was chosen to be one ten-millionth part of the distance from the equator to the pole of the earth at a particular meridian, and was fixed in con- erete form as the length of a platinum bar, which has been carefully preserved in Paris. Subsequent and more accurate measurements have given a slightly differ- ent value for the circumference of the earth, so that the meter is known not to be, as originally intended, just one ten-mill- ionth of a particular quadrant of the earth. The meter has, however, not been changed, its value being fixed by the length of the platinum standard and not by the earth. Thus the platinum bar has become the primary standard of length, instead of a secondary standard as was originally intended. This is a happy re- sult, for the difficulties of comparing a meter with the dimensions of the earth is too great to make the dimensions of the earth of any value as a standard of length. The original standard meter has been reproduced many times in platinum and iridio-platinum, and many of the civilized nations of the earth possess such duplicates. We have two of them at the bureau of standards in Washington, one of which was recently taken to Paris by Mr. Fischer, and recompared with the standards of the inter- national bureau. The results showed al- most perfect agreement with the compari- son made fifteen years previously, the dif- ference, if any, being not greater than about 0.5 of a micron, that is, 1/50,000 inch. This is one part in 2,000,000 of the SCIENCE. (N.S. Vor. XXT. No. 527. length of the bar and represents about the limit of accuracy obtainable in comparisons of this nature, although the computed probable error of the observations was only .02 of one micron, or less than a millionth of an inch. The third fundamental unit, that of mass, has likewise varied in different countries and in different ages. The most widely used unit was the pound, and before the metric system came into use there were hun- dreds of different pounds in use in Europe, differing from country to country and from province to province, and varying also ac- cording to the commodity to be measured. The ancient Roman pound was equivalent to a little less than twelve of our avoirdu- pois ounces, and from it were derived the various Italian pounds, varying in value from the Venice light pound, equivalent to about eleven of our avoirdupois ounces, — and the Naples silk-pound and the Milan light pound of about twelve ounces to the Piedmont pound of about thirteen ounces and the Venice heavy pound of about sev- enteen ounces. There were silk pounds, and chocolate pounds, and table pounds, and goldsmith pounds and _ medicinal pounds; there were lght pounds, and heavy pounds, and half-heavy pounds and extra-heavy pounds. There were pounds of 12, 14, 15, 16, 17, 18, 20, 21, 22, 24, 2ay 30 and 36 ounces, and the ounces had vary- ing values in different countries and in different provinces of the same country. To remedy this distressing confusion the French, in 1799, at the same time the meter was chosen, adopted the kilogram as the unit of mass, fixing it concretely in a cylin- drical mass of platinum, which was intend- ed to be equal to the mass of a eubie deci- meter of water at the temperature of its maximum density. This, lke the meter, was designed to be a natural unit that could be derived originally at any subse- quent time and in any country. But, as Fresruary 3, 1905.] in the ease of the meter, later determina- tions showed that the kilogram was not exactly equal to the mass of a cubie deci- meter of water as was intended, and hence the platinum secondary standard was adopted as a primary standard of mass and no further attempt made to make it a nat- ural unit. All other countries using the metric system use carefully constructed copies of this original kilogram as their standards cf mass. ‘The process of weigh- ing is even more accurate than the com- parison of lengths, so that the standard kilograms of the various countries of the world are practically perfect duplicates of the original and of each other. In 1875 a conference of the representa- tives of seventeen nations was held in Paris and a permanent international bureau of weights and measures was established and is still maintained. It is located at Sévres, near Paris, and is supported jointly by the participating nations. Its duties are to eare for the fundamental standards of length and mass, to furnish accurately ad- justed copies of the same, and to compare standards which may be returned from time to time. Some other testing is done, including the calibration of thermometers. The work is of the highest order of accu- racy and leaves little to be desired so far as standards of length and mass are con- cerned. The metric system has been adopt- ed by nearly all the civilized nations of the world, excepting Great Britain and her colonies and the United States, and is uni- versally used throughout the world for sci- entific purposes. The electrical units are all based on the metric system and hence electrical engineers employ the metric sys- tem almost exclusively, even in this coun- try. The gain to science and commerce due to the adoption of the metric system can searcely be overestimated and it is to be hoped that it will scon be adopted by the English-speaking countries of the world. SCIENCE. 165 The avoirdupois standard for the United States was defined in 1830 as 7000/5760 of the Troy standard pound of the mint, which in turn was a copy of the British Troy pound, derived from the standard of Queen Elizabeth made in 1588. The latter was derived from the standard of Edward IIl., and this is said to have come from the city of Troyes, France, hence the name, Troy pound. The metrie system was legal- ized in the United States in 1866, and the meter was declared to be equivalent to 39.37 inches and the kilogram to 2.204 pounds. The international bureau began its work in 1879. The iridio-platinum prototypes cf the metric standards were received in this country in 1889. These were so much superior as standards to the brass standard pound and _ the yard, that in 1893 the metric standards were adopted as fundamental standards by the United States and the pound and yard were defined in terms of them. Thus the metrie system is not only legalized in this country, but our fundamental standards are the meter and kilogram and all our weights and measures are derived from these metric standards using the legal equivalents. Few people, perhaps, realize how need- lessly complex our system of weights and measures really is. Instead of a single unit of weight and of length with multiples and submultiples having ratios of ten, and a unit of volume simply related to the unit of length, as is the case in the metric sys- tem, we have a multiplicity of units and all kinds of odd ratios for the multiples and submultiples. I beg your indulgence for a moment while I remind you of some of the absurdities of our system. But first recall how much simpler and more con- venient our decimal coinage is than the English coinage. Nothing could be simpler than the expression of values in dollars and cents; the use of pounds, shillings and bronze 166 pence, to say nothing of guineas, crowns and farthings with their odd ratios, being cumbersome in But our weights and measures are far more cum- bersome and complicated than the English coinage. We weigh most merchandise by avoirdupois weight, gold and silver by troy weight, medicines by apothecaries’ weight, diamonds by diamond carat weight. We have dry quarts and liquid quarts, long tons and short tons, and a hundredweight is not 100, but 112 pounds. Coal is usually purchased at wholesale by the long ton and retailed by the short ton. A bushel some- times means 2,150.4 cubic inches and some- times it means a certain number of pounds weight of a commodity. The American bushel is derived. from the old English Winchester bushel, but the legal English bushel of the present day is larger by 69 cubie inches. On the contrary, the Eng- lish gallon is much larger than the Amer- ican gallon, the difference amounting to about 20 per cent. We measure wood by the cord, stone by the perch, earth by the cubie yard. Moreover, among the different states of the union are considerable differ- ences in custom and in legal equivalents. We are, of course, much better off than the countries of Europe were a century ago, but the difference is all too small. Our medieval system of weights and measures is, however, too deeply rooted to be easily displaced. But the metric system is being used in this country more than is generally realized and our rapidly grow- ing foreign trade is bringing it more than ever to the attention of merchants and manufacturers. In England a strong ef- fort is being made to adopt the metric system, with the hope that ultimately a decimal system of currency may also be adopted. The English colonies are even more progressive than the mother country, and strong influences are at work to secure the decimal system throughout the British comparison. SCIENCE. [N.S. Vou. XXI.

It will be greatly to the advan- tage of the United States to keep abreast of this movement, and not to be the last among the civilized nations of the world to throw off the ineubus of an incoherent system of weights and measures, whose chief claim lies in the fact that it is in general use. The testing of lengths and masses con- stitutes one of the most important branches of the work of the bureau. As I have said, this work has been done by the government for many years, but the facilities for the work are being immensely improved by the bureau so as to extend the range and imerease the accuracy of the work. The new laboratories will contain many new balances and comparators and every pre- caution is being taken to secure the most favorable conditions possible for precision work. When the installation is completed it will probably be the best of the kind in the world. I have said that the three fundamental units of measure are those of length, mass and time, or the meter, kilogram and sec- ond. From these are systematically de- rived various other units, all forming what is often called the centimeter-gram-second system, or, more briefly, the ¢.g.s. system. It is not my purpose to enumerate the vari- ous derived units which are employed in scientific and technical work, but rather to describe briefly some of those employed in the testing and research work of the bu- reau. And first let me speak of the work in heat and thermometry. The testing of thermometers is one of the most important branches of the work of the bureau. This work is under the charge of Dr. Chas. W. Waidner, who is personally known to some of you. Dr. Waidner and his assistants have devoted a great deal of effort to the acquisition of reliable standard thermom- eters and to the investigation of instru- ments and methods. In this they have Fepruary 3, 1905.] availed themselves of the results of the magnificent work that has been done in this field in Europe, more especially at the Bureau Internationale and the Reichsan- stalt, and by the thermometer makers of France and Germany. For our present purpose thermometers may be conveniently grouped as follows: (1) Precision mereury thermometers, to be used as standards or for scientific purposes. They are calib- rated very elaborately and are capable of high accuracy. (2) Ordinary mercury thermometers and clinical thermometers. We test clinical thermometers by the thou- sand and we hope before long that they will come to us by the tens of thousands. Clinical thermometers often change if grad- uated new, and hence they ought always to be aged, tested and certified to insure their eecuracy. (3) High temperature mercury thermometers of hard glass, with nitrogen under pressure above the mercury column, reading up to 550° C. (or about 1000° F.). (4) Platinum resistance thermometers, thermocouples and other forms of pyrom- eters suitable for measuring furnace tem- peratures up to 1600° C. (about 2900° F.). Such instruments are used in many manu- facturing processes, as well as in research problems and hence are found both in scientific and in technical laboratories. (5) Optical pyrometers for measuring the tem- peratures of the hottest furnaces and, ap- proximately, even the temperature of the electric are, the highest temperature attain- able by any known means, namely, about 3950° C. (or 7150° F.). An investigation on this subject at the bureau has recently been published by Drs. Waidner and Bur- gess. (6) Low temperature thermometers, for temperatures below the freezing point of mereury, even down to the temperatures of liquid air and of liquid or solid hydro- gen. Such thermometers use pentane or toluene; or a copper-constantan thermo- couple is employed. For the very lowest SCIENCE. 167 temperatures helium gas is used, helium being the only gas not liquefied at the tem- perature of solid hydrogen, namely, about 16° above absolute zero, or 257° C. (or 430° F.) below the freezing point of water. The bureau has done more or less testing in all these lines except the last, but hopes soon to add this to the list of tests which are made. From the temperature of solid hydrogen to that of the electric are is a wide range, indeed, and a very considerable equipment of apparatus and machinery is necessary to produce and to measure any tempera- ture throughout this range. For the high- er temperatures numerous gas and electric furnaces are required. For the lower tem- peratures a refrigerating plant and appa- ratus for liquefying carbon dioxide, air and hydrogen are required. The bureau has recently purchased the low temperature plant which was operated as an exhibit by the British government at the St. Louis Exposition. This was one of the most in- teresting exhibits of the entire world’s fair. Liquid hydrogen was produced in larger quantity by this plant than had ever been done before, more being made and used in publie demonstrations during the season than the total amount that has been pro- duced since hydrogen was first liquefied. Solid hydrogen is also produced by the apparatus. The optical work of the bureau is not so fully established as the work in weights and measures and heat and thermometry, but three well-trained specialists are de- voting themselves to it and a fourth is soon to be appointed. The work of research and testing in this section, which has been taken up or is soon to be begun, includes the investigation of the optical properties of instruments and of materials; the appli- eation of interference and other optical methods to linear and angular measure- ments; the investigation of the spectra of 168 vacuum tubes and other phenomena in con- nection with the passage of electricity through gases at reduced pressure; and the investigation of questions connected with the polariscopic analysis of sugar and the testing of polariscopes. The latter subject is of special impor- tanee on account of the use of polariscopes in determining the duty on sugar imported into the United States. The bureau has undertaken, at the request of the Treasury Department, to supervise the work of polari- seopie analysis of sugar in all the custom- houses of the country. Sugar is the chief source of revenue among articles imported, the duties .collected by the government amounting to over $60,000,000 per annum. The duty on each importation is deter- mined by the angle through which a beam of polarized light is rotated when passed through a solution of a sample of sugar, the percentage of pure sugar being shown by a specially prepared table when the angle of rotation has been determined. For some years a difference has existed be- tween the experts of the government and those employed by the sugar interests as to the effect of temperature upon the indica- tions of the polariscope, and although the difference is only a fraction of one per cent., it amounts to a large sum when ap- plied to the hundreds of millions of dol- lars paid in duty during the last few years. The question is being contested in the courts and in the meantime the bureau is making some careful investigations on the subject in the interest of the government. Another line of the bureau’s work not yet fully established is the testing of gas and water meters, pressure gauges and manometers for high and low pressures, engine indicators and the determination of the strengths of materials including cem- ents and other building materials. This will probably develop into a very impor- tant branch of our work, in which we can SCIENCE. [N.S. Vou. XXI. No. 527. be of much service to scientific and tech- nical laboratories, as well as to the govern- ment and the public. The official testing of scales, measures of length and volume, gas, water and elec- tricity meters and other instruments by which the commodities purchased by the people are measured is not done in this country as thoroughly as it ought to be. In very few cities do the sealers of weights and measures go about systematically test- ing the instruments employed for measur- ing merchandise. England surpasses us in looking after the interests of the people in this particular. One of the functions of the bureau is to educate the public to the importance of this work. A step in this direction is the national convention of sealers of weights and measures to meet next month in Washington in response to a call issued by the bureau of standards. The various lines of testing and research which have so far been mentioned, namely, weights and measures, heat and thermom- etry, hight and optical instruments, and en- gineering instruments, are included in the first division of the work of the bureau of standards. The second division includes electricity and photometry. In the early days of its development electricity was es- sentially a qualitative science; its modern history has seen it become distinctly quan- titative, and its wonderful development has been largely, if not mainly, due to the use of measuring instruments in studying and applying it. The three fundamental units of measure are the ohm, the unit of resist- ance; the ampere, the unit of current; and the volt, the unit of electromotive force. These are so related by Ohm’s law that — | when two are defined the third becomes fixed and can be determined by the use of the other two. These units are not arbi- trarily chosen, but are determined by ex- perimental investigation. Their magni- tudes depend upon the fundamental units }EBRUARY 3, 1905.] of length, mass and time, and these having been selected (namely, the centimeter, eram and second), the definitions or speci- fications of the electrical units follow log- leally, but their conerete expression in actual standards that can be employed in electrical measurements ean only be at- tained after most painstaking researches in what are called absolute measurements. The two of these three units which have been so determined are the ohm and the ampere. As all other electrical units are based upon these, it is of the greatest im- portance that they be determined with the utmost exactness. At the International Electrical Congress at Chicago, in 1893, they were redefined in accordance with the results of the best determinations made up to that time. The ohm is specified in terms of the resistance of a column of mercury 106.3 em. long, having a cross-section of one square millimeter; the ampere in terms of the quantity of pure silver it will de- posit electrolytically per second from a solution; the volt in terms of the electro- motive force of the standard Clark cell. An immense amount of work has been done by numerous investigators in various coun- tries of the world in the determination of the values of these electrical units, and the figures adopted in the definitions un- doubtedly come very near the truth. Nevertheless, we know from subsequent work that at least two of these units are very slightly in error, and one of the most important problems before the bureau of standards is the redetermination of these fundamental units. The error in ques- tion is small, so small as to be of no eonse- quence in engineering and commercial work. But scientifically it is important, and as instruments and methods are im- proved year by year, any small discrep- ancies in our fundamental units become of more and more significance. The Na- tional Physical Laboratory of England, SCIENCE. 169 the Physikalisch-Technische Reichsanstalt of Germany and the National Bureau of Standards, as well as a few private investi- gators in this country and abroad, are all working in the same direction. The recent International Electrical Congress at St. Louis provided for the formation of an in- ternational commission, whose function it shall be to foster and in some degree direct and coordinate researches of this character. This commission will probably organize and enter upon its work during the coming year. The difficulties to be overcome are so great that only the most elaborate re- searches carried out under the most favor- able circumstances ean be expected to bring us appreciably nearer the desired goal. - Two researches at the bureau of standards during the past year gave re- sults of value preparatory to the rede- termination of the ampere in absolute measure. Orte was by Dr. Wolff, showing how to overcome one of the defects of the standard cell; a new method of preparing the mercurous sulphate yielding a erystal- line product which gives cells of more uni- form electromotive foree than formerly. Professor Carhart, of Ann Arbor, who has been engaged upon this subject for some time, arrived independently at the same result even earlier, the results being an- nouneed by both men at the same meeting in Washington in April last. The other investigation was by Dr. Guthe, who, after carefully studying all the various forms of silver voltameters which have been pro- posed, showed that although different kinds gave slightly different results, cer- tain ones when properly handled, gave practically identical results, and hence could be depended upon for measuring eurrent to a very high order of accuracy. Dr. Wolff is continuing his work on stand- ard cells and Dr. Guthe is now engaged in the absolute measurement of current, by means of a new electrodynamometer. 170 I have been engaged, with the assistance of Mr. Grover, Dr. Lloyd and several other members of the bureau, in the absolute measurement of electric capacity and in- ductance and in the investigation of elec- trical measuring instruments, more espe- cially for the precise measurement of al- ternating current, voltage and energy. These investigations have involved the con- struction of much new apparatus, as well as the thorough study of some well-known instruments. One of the practical prob- lems in connection with the accurate meas- urement of capacity or inductance is the determination of the frequency of the in- terrupter or of the alternating current em- ployed. This usually amounts to obtain- ing the speed of some kind of motor, often an electric motor. For some kinds of work, to be within one per cent. is considered suf- ficiently accurate. For other cases one tenth of one per cent. is none too good. In still others one hundredth of one per. cent. is deemed necessary. In this work we sought to get the frequency to a thou- sandth part of one per cent. This re- quired a very perfect control of the speed, and yet by attention to all the sources of disturbances, and by the use of a very sensitive indicator, the desired result was obtained and an important additional step taken in absolute measurements. Many other interesting and important questions are being investigated, and work enough for years is already before us. These particular examples of the work at the bureau have been cited, not because I presume that you are especially interested in the problems themselves, but rather to illustrate the kind of research work we are doing. The work of testing is being carried on at the same time. Resistance standards, current standards, standard cells, wheat- stone bridges, potentiometers, magnetic in- struments, current instruments, voltmeters, SCIENCE. [N.S. Vou. XXI. No. 527. wattmeters, condensers, inductances and many other electrical instruments have come to us from manufacturers, universi- ties, technical laboratories and departments of the national government. To be abie to get reliable standards and to have in- struments calibrated at a nominal cost is a boon to all careful experimentalists. Heretofore it has often happened that the burden of the work in a given investigation has been to calibrate the instruments em- ployed, and often the facilities at com- mand were insufficient to yield results of high accuracy. Within the last three years (that is, since the bureau has been testing instruments) there has been a marked im- provement in the quality of some kinds of electrical instruments made in this coun- try. It is now so easy to determine whether a resistance box guaranteed by the maker to be correct to one fiftieth of one per cent. fulfils the guarantee, that the maker is compelled to use correct standards and to adjust his resistances carefully in accord- ance with the same. Probably the most interesting collection at the St. Louis Exposition from the stand- point of physical science was the magnifi- cent exhibit of scientific instruments made by Germany. There was a time not so very long ago when France and England surpassed Germany in the production of scientific instruments. But the giant strides which Germany has made in the last twenty years has left other countries in the rear, and this wonderful progress has been largely due to the wise encourage- ment and assistance offered to instrument makers by the German government. This assistance has taken various forms, but the principal factor has probably been the work of the Reichsanstalt and the Normal Aich- ungs Kommission, the two government laboratories doing the work which the bu- reau of standards aims to do in the United States. They have set a high standard for FEBRUARY 3, 1905.] scientific instruments, and have not only shown how defects could be corrected, but have developed the theory and the design of many new instruments. All this has occurred so recently that it is not gener- ally known in the United States, and Ger- man instruments are not as largely used as they deserve to be. We hope that the next few years may witness a similar impetus in the production of scientific instruments in this country, and that the United States may come to hold the same enviable posi- tion with respect to scientific instruments in general that she now does with respect to tools and labor-saving machinery and to certain special classes of scientific in- struments. The advantage of having instruments and standards of high accuracy for engi- neering and research work is obvious and needs no proof. I wish, however, to point out the advantage of using such instru- ments as far as practicable for purposes of instruction, especially in the more ad- vanced laboratory courses. If the appa- ratus is not accurately adjusted the careful student and, perhaps, his instructor as well, is prone to lose valuable time in trying to locate errors that are inherent in the appa- ratus, or in striving for a degree of accu- racy which is unattainable with the instru- ments employed. On the other hand, when the apparatus is known not to be correct it is so easy to attribute to the instruments any discrepancies in the results that care- fess reading and hasty work may possibly be encouraged. It isa great delight to the real lover of quantitative experimental work, of whom a great many are to be found in almost any college class, to do a piece of work with precision instruments and obtain an accurate result, duly checked by proper variations of the experiment. The educational value of such work is cer- tainly greater than when only roughly done; the pleasure derived is incomparably SCIENCE. pba greater. It is by no means necessary that all the instruments of a laboratory be sent away to be tested. If only the laboratory possesses correct standards and suitable comparing apparatus, the calibration or adjustment of most of the other instru- ments furnishes excellent experimental work for the students and assistants of the laboratory. Another important section of the work of the bureau is photometry. This is really optical rather than electrical, but owing to the fact that the chief work is with electric lamps and a very considerable electrical equipment is required, it is grouped with the electrical in our organization. The standards employed in photometric testing are less satisfactory than in most other branches of physical measurements. The quantity of light emitted by a given source is usually expressed in candle power; the ordinary ineandescent electric lamp, being approximately equivalent to sixteen stand- ard candles, is called a sixteen candle- power lamp. The candle as a standard of measure has passed out of vogue, but hght is still expressed in candle power. Various sources of light have been proposed as standards, the Hefner lamp burning amyl- acetate, being most used as a primary standard. As working standards specially prepared incandescent lamps are generally used, and are quite satisfactory. Greater progress has been made in recent years in developing photometers and the auxiliary apparatus for comparing lamps than in perfecting a primary standard of illumina- tion. Although the initial equipment of the bureau for this work is not yet com- plete, we have already done considerable testing, especially in rating lamps to be used as standards by manufacturers and others, and in testing lamps purchased by the various departments of the govern- ment. Millions of incandescent lamps are sold each year on carefully drawn specifi- cations, and it is a matter of considerable importance to know whether the conditions of the contracts are met by the manufac- turers. In addition to the exhibit made by the bureau of standards in the government building at the St. Louis exposition, an electrical laboratory was equipped and the electricity building. This was done at the request of the exposi- tion management, the object being twofold; first to exhibit a working electrical labora- tory, and, second, to do electrical testing for the jury of awards, for the railway test commission, and other electrical in- terests at the fair. The laboratory build- ing, which was within the palace of elec- tricity, and extended along one of its walls for a distance of about 175 feet, was di- vided into six rooms. Notwithstanding the fact that it was a temporary structure the laboratory possessed many of the appoint- ments of a permanent installation; and, although many disadvantages and limita- tions were experienced in doing scientific work amid such surroundings, we succeed- ed in doing a good deal of satisfactory work, including both research and testing. So complete a laboratory has never been installed in any previous world’s fair, and it proved to be of considerable interest both to visitors and to those electrical in- terests which availed themselves of its fa- cilities for testing instruments. FEBRUARY 24, 1905.) It is a matter of measurement that but one fourth of the water in the Niagara River passes over the American Falls. The sill of the falls is ten feet higher on the American side than on the Canadian. How easily the water is driven entirely out of the American channel is seen by the ice dams of the past few years, which, gorging the stream from the upper end of Goat Island to the American side, have turned the water from that channel so that one can cross the bed of the river dry-shod. Let then, from one fourth to one third of the water be permanently abstracted from the river, and the American Falls will be permanently dry. The production of power actual and immediately contemplated by the five companies within their charters will con- sume 48,400/224,000 of the water, or 1/5 —. With the estimated abstraction of water by the sixth (American) company this fraction becomes 58,400/224,000 or 1/4—. Should the proposed additional Canadian plans be effected the proportion will become 88,396/224,000 or 1/3—. In any one of these cases the danger limit is reached and the perpetuity of the American Falls now hangs by the slender thread of improbability that these companies shall produce to their statutory limitations or find a market for their product. It is authentically stated that 800,000 tour- ists visit Niagara annually, bringing an enormous revenue to the place. As soon as the world learns that New York and Canada have shorn this famous place of its beauties, this source of industrial prosperity will be gone. While these magnificent schemes of power development are putting to shame a sentiment of proper pride which should be national rather than local, unlimited horse- power lies idle in the region where these companies hope to find their market and in the development of this none of the finer manifestations of natural power and none of the finer sentiments of mankind would be as- sailed. The address was a strong presentation of the subject and the press of the city joined in the protest against the destruction of the falls. J. E. Kirxwoop, Corresponding Secretary. SCIENCE. 313 DISCUSSION AND CORRESPONDENCE. CONSULTING EXPERTS IN LIBRARIES. To Tue Eprror or Science: Dr. Francis B. Sumner’s letter, published in Scrmmncr, Jan- uary 13, seems to offer an appropriate oppor- tunity for calling attention to certain note- worthy developments at the Library of Con- gress during the administration of Dr. Her- bert Putnam. Dr. Sumner urges the desira- bility of employing, in connection with one of our great libraries, ‘a staff of consulting _experts, men of the rank of college professors, whose duty it should be to furnish definite bits of information in response to legitimate ques- tions, or, at least, to guide the seeker on his way * * * the establishment of a sort of hu- man encyclopedia as an adjunct to the library.’ While this ideal has not yet been attained at the Library of Congress, a remarkable de- velopment in this direction has taken place during the last few years. It is the function of the Division of Bibliography, established in 1900, not only to prepare and publish lists of references on special topics, principally those of current political interest, but also to supply bibliographical information in reply to inquiries received by mail. The reference work of this character has been mainly in the fields of social and political science and his- _tory. As, however, the collection of scientific lit- erature has recently been reclassified and is now in process of being recatalogued, it has become possible to undertake similar work in science. There are on the staff of the library at the present time several specialists repre- senting different sciences, and it is always possible to consult others associated with va- rious branches of the government service. Furthermore, it being part of the policy of the Librarian of Congress to make the collec- tion of bibliographies, indexes, library cata- logues, etc., as complete as possible, unusual resources in the way of bibliographical tools are available at the library. A Science Sec- tion of the library, in charge of the under- signed, has accordingly been organized re- cently and one of its functions is to carry on the reference work in this field, both for in- vestigators at the scientific bureaus in Wash- 314 ington and in answer to legitimate inquiries by mail. Under these circumstances it seems that the facilities now offered by the Library of Con- gress meet the need indicated in Dr. Sumner’s letter to a very considerable extent, and fur- ther advances in this direction will occur if it appears that valuable service can be ren- dered. I conclude by inviting the readers of ScinNCE to make use of these new facilities whenever the library resources to which they have access are inadequate to the needs of the investiga- tions which they have in hand. Communica- tions should be addressed to the Librarian of Congress, and should be marked ‘ Science Section’ if they are-inquiries referring to the mathematical, physical or natural sciences. J.

Department of Agriculture, describing a method of storing and indexing microscopic slides. The Bausch and Lomb Optical Company have designed and are selling an excellent cabinet with card system which has all the advantages claimed by Mr. Marlatt for his and lacking only the envelopes, which I can not but think must be somewhat inconvenient. These cabinets are made in three sizes, hold- ing 500, 1,500 and 3,000 slides respectively. Tiers of trays, each running in its own groove, are constructed to take slides of various sizes. At the bottom are drawers (one, two or three) containing separate cards for every slide, on each of which is printed a form for register- ing the slide: Tray No.—Series No.—Name of Slide—Stain—Mounted in— and two lines for other data. There are also printed guide cards from A to Z. The objects being recorded on separate ecards, the removal of slides necessitates simply the removal of its corresponding card, while the addition of slides requires only the filling out and insertion of new cards. Olassi- fication thus, it will be seen, becomes exceed- ingly simple. The slides may be rearranged SCIENCE. [N.S. Vou. XXI.

DOPPLER’S PRINCIPLE AND LIGHT-BEATS. THERE is a beautiful lecture experiment in illustration of Doppler’s principle due, I be- lieve, to Koenig. A vibrating tuning fork of high pitch, say 2,000 vibrations per second, is moved to and fro near, and at right angles to, a reflecting wall. The waves coming from the fork and (virtually) from its image back of the wall are changed in length by the op- posite motions of fork and image with the result that very audible beats are heard. With a fork of the pitch mentioned, a speed of three feet per second gives beats at the rate of about eleven per second. Although special forks are made for this experiment, they are quite unnecessary. An ordinary © 512 fork of Koenig’s pattern gives a very shrill tone when strongly bowed near the shank and answers the purpose admirably. If the fork is held stationary and the reflecting surface is moved, the effect is the same on account of the motion of the fork’s image. Attempts to secure visible beats by means of light waves of slightly different wave-length have met with no success, partly on account of rapid changes of phase, and partly because of the difficulty of securing two sources whose vibration frequencies are nearly enough equal. Thus if we assume (what is most likely not true) that the failure to observe interference fringes with differences of path greater than, say, 30 em. indicates a change of phase, this would indicate 10° or more changes of phase per second. On the other hand, should we take the two D lines as sources there would be about 10” beats per second. It is evidently almost hopeless to attempt to secure visible light-beats in this manner. If we consider Doppler’s effect, however, the case is quite otherwise. The second form of Koenig’s ex- periment, viz., that in which the reflector is moved, is in principle almost exactly anal- ogous to Professor Michelson’s interferometer. FEBRUARY 24, 1905.] In this instrument the alternations in bright- ness at any point in the field when the slide is moved are beats due to the Doppler effect just as truly as are those heard in the second form of Koenig’s experiment. ALBERT B. Porter. CHICAGO, January 14, 1905. NOTE ON THE BROAD WHITE FISH. In the Proceedings of the American Philo- sophical Society of Philadelphia, XLIIL, 1904, p. 451, plates VIII. and IX., I have wrongly identified the broad white fish, or Coregonus kennicotti Jordan and Gilbert, as the humpback, or Coregonus nelsonii Bean. My error was due largely to lack of material, ignorance of the species from autopsy, and the fact, as I have since discovered, that C. nelsonit does not always exhibit the well-de- veloped hump like that of the type. Possibly when the Siberian forms are carefully studied the nomenclatures of these fishes will be more stable. Henry W. Fow ter. ACADEMY OF NATURAL SCIENCES, PHILADELPHIA, February 5, 1905. RECENT ZOOPALEONTOLOGY.* Durine the past thirteen years great ad- vances have been made in our knowledge of the ancient mammalian life of North Amer- ica, especially through the explorations in the Rocky Mountain region carried on by the Carnegie, Field Columbian and American Natural History Museums. The long Ter- tiary period has been clearly subdivided into a series of stages and substages. This enables paleontologists to record more accurately than ever before the time of arrival and departure of the larger and smaller quadrupeds from North and South America, Asia, Europe, Af- rica, and to determine more precisely when the connection of North and South America was interrupted by a gulf flowing between the Atlantic and Pacific Oceans, and when the connection was again made by the elevation * Abstract of a lecture delivered by Professor Osborn before the Society of Naturalists at the Philadelphia meeting.

The available timber per township runs from ‘3,000 feet B. M. amid the high mountains, up to 59,000 feet B. M. in the northwest corner’ (Dodwell and Rixon). What with fallen timber and under- growth of ferns and shrubs the forest is a veritable jungle. By hard work one can travel a quarter of a mile an hour off the trails! Salal-berry (Gaultheria shallon) and species of Rubus, Vaccinium and Ribes contribute largely to the denseness of the jungle, and furnish abundant food for man and _ beast. The matted tree tops admit only a gloomy light below, and the darkness is deepened by great blankets of Selaginella (S. oregana) and bearded lichen (Usnea) depending from the branches. A thick bed of moss covers all the ground and swathes the bases of the tree trunks. Above 2,000 feet, however, the forest is quite open, but travel is impeded much more seriously by the impassably sharp hog- backs and steep canyon walls. The moun- tains slope more gently southward than on other sides, and it is believed that Mt. Olym- pus could be reached from the valley of the Quiniault River. The major part of the peninsula is held as the Olympic Forest Re- serve. Two reports on this by Dodwell and Rixon (1, U. S. Geol. Surv., 21st Ann. Report, Part V., 1900; 2, ditto,. Professional Paper No. 7, 1902) with maps and illustrations give the best accounts yet available concerning the region. The fauna is equal to the flora in richness. Black bears, panthers, wild cats and wolves are numerous. A few squirrels and the moun- tain beaver are found. Deer and elk are plentiful. The garter snake is the only rep- tile. Wild duck and pheasants are occasional, and the familiar robin is seen about the houses. Salmon and trout of several kinds abound in all streams that are large enough. Quiniault salmon is said to be the finest on the coast. The report of the expedition from the Field Columbian Museum on the mam- mals of the Olympic Peninsula is the only record of its fauna. In each river valley a distinct tribe of In- dians originally made its home. The Makah SCIENCE. 393 at Cape Flattery were studied by Swan, and are an extremely interesting group. ‘The Quillayutes and Quiniaults would equally re- pay an immediate investigation; but their old habits are rapidly vanishing before the gov- ernment schools. Whites began to settle the Quiniault Valley in 1892, but the movement is very slow on account of the difficulty of clearing land and of getting produce in and out. It is estimated to cost $200 an acre to remove the timber enough for farming op- erations. Here, then, is almost virgin soil for any kind of scientific investigation. Just enough has been done to enable the student to start intelligently and progress without interrup- tion on any phase of this interesting region. Henry S. Conarp. JOHNS Hopkins UNIVERSITY, February, 1905. ° es QUOTATIONS. DR. OSLER ON THE PERIODS OF A TEACHER’S LIFE.* I am going to be very bold and touch on another question of some delicacy, but of infinite importance in university life, one that has not been settled in this country. I refer to a fixed period. for the teacher, either of time of service or of age. Except in some proprietary schools, I do not know of any in- stitutions in which there is a time limit of, say 20 years’ service, as in some of the London hospitals, or in which a man is engaged for a term of years. Usually the appointment is aut vitam aut culpam, as the old phrase reads. It is a very serious matter in our young uni- versities to have all of the professors growing old at the same time. In some places only an epidemic, a time limit, or an age limit, can save the situation. I have two fixed ideas well known to my friends, harmless obsessions with which I sometimes bore them, but which have a direct bearing on this important problem. The first is the comparative uselessness of men above *From his valedictory address at the Johns Hopkins University, given at the annual com- memoration exercises on February 22, and printed in the Journal of the American Medical Associa- tion. 394 40 years of age. This may seem shocking, and yet read aright the world’s history bears out the statement. Take the sum of human achievement in action, in science, in art, in literature—subtract the work of the men above 40, and, while we should miss great treasures, even priceless treasures, we should practically be where we are to-day. It is difficult to name a great and far-reaching conquest of the mind which has not been given to the world by a man on whose back the sun was still shining. The effective, moving, vitalizing work of the world is done between the ages of 25 and 40 years—these 15 golden years of plenty, the anabolic or constructive period, in which there is always a balance in the mental bank and the credit is still good. In the science and art of medicine there has not been an advance of the first rank which has not been initiated by young or compara- tively young men. Vesalius, Harvey, Hunter, Bichat, Laennee, Virchow, Lister, Koch—the green years were yet on their heads when their epoch-making studies were made. To modify an old saying, a man is sane morally at 30, rich mentally at 40, wise spiritually at 50— or never. The young men should be encour- aged and afforded every possible chance to show what is in them. If there is one thing more than another upon which the professors of the university are to be congratulated, it is this very sympathy and fellowship with their junior associates, upon whom really in many departments, in mine certainly, has fallen the brunt of the work. And herein lies the chief value of the teacher who has passed his climacteric and is no longer a productive factor; he can play the man midwife, as Socrates did to Thesetetus, and determine whether the thoughts which the young men are bringing to the light are false idols or true and noble births. My second fixed idea is the uselessness of men above 60 years of age, and the inealcul- able benefit it would be in commercial, polit- ical and in professional life if, as a matter of course, men stopped work at this age. Donne tells us in his ‘ Biathanatos’ that by the laws of certain wise states sexagenarii were precipitated from a bridge, and in Rome SCIENCE. [N.S. Vou. XXI. No. 532. men of that age were not admitted to the suffrage, and were called depontani because the way to the senate was per pontem and they from age were not permitted to come hither. In that charming novel, the ‘ Fixed Period,’ Anthony Trollope discusses the prac- tical advantages in modern life of a return to this ancient usage, and the plot hinges on the admirable scheme of a college into which at 60 men retired for a year of contempla- tion before a peaceful departure by chloro- form. That incalculable benefits might fol- low such a scheme is apparent to any one who, like myself, is nearing the limit, and who has made a careful study of the calamities which may befall men during the seventh and eighth decades! Still more when he contemplates the many evils which they perpetuate unconsciously and with impunity! As it can be maintained that all the great advances have come from men under 40, so the history of the world shows that a very large proportion of the evils may be traced to the sexagenarians—nearly all the great mistakes politically and socially, all of the worst poems, most of the bad pictures, a majority of the bad novels, and not a few of the bad sermons and speeches. It is not to be denied that occasionally there is a sexa- genarian whose mind, as Cicero remarks, stands out of reach of the body’s decay. Such a one has learned the secret of Hermippus, that ancient Roman, who, feeling that the silver cord was loosening, cut himself clear from all companions ‘of his own age, and be- took himself to the company of young men, mingling with their games and studies, and so lived to the age of 153, puerorum halitw re- focillatus et educatus. And there is truth in the story, since it is only those who live with the young who maintain a fresh outlook on the new problems of the world. The teacher’s life should have three periods —study until 25, investigation until 40, pro- fession until 60, at which age I would have him retired on a double allowance. Whether Anthony Trollope’s suggestion of a college and chloroform should be carried out or not, I have become a little dubious, as my own time is getting so short. Marcu 10, 1905.] REPORT OF THE COAST AND GEODETIC SURVEY FOR 1904. Tue report of the Coast and Geodetic Sur- vey for 1904 is a record of manifold labors and results which have for their theater of action an area practically coterminous with that of the United States and all its island possessions. The main body of the report con- tains a detailed account of the wide range of important duties devolving upon this bureau, and in the appendices we have a presentation of discussions and results which must prove of great economical value and interest to sur- yeyors, engineers, navigators and physicists. The resurveys and developments impera- tively required to show the changes in harbors and approaches, due to works of improvement or the ceaseless action of natural causes along the Atlantic, Pacific and Gulf coasts of the United States, and to meet the ever-increasing demands of our commerce and navy for up-to- date charts, particularly of the waters of Alaska, Porto Rico, Hawaii and the Philip- pines, gave constant employment to the eleven vessels available for these duties. The hy- drography was prosecuted within the limits of the waters of sixteen states and territories and the topography was carried on in nine. In Alaska the work included the continua- tion of the survey of Prince William Sound, the survey of Controller Bay and a deep-sea examination from the Strait of Juan de Fuca to Prince William Sound, preliminary to the laying of a deep-sea cable from Seattle to Valdez. The Porto Rico work was continued in certain bays and harbors as well as in the development of the conditions in the off-shore waters. In the Philippine Archipelago the survey has secured the cooperation of the insular government and a detailed résumé shows a most satisfactory progress of the tri- angulation, hydrographic, topographic, mag- netic and astronomical operations. By utiliz- ing native assistance in the Manila sub-office twenty-one charts were prepared for publica- tion during the year, and the outcome of the experience with Filipinos as draftsmen, com- puters and engravers is the gratifying demon- stration that they will prove equally as com- petent as the Hindoos have been found in the SCIENCE. 395 British Indian operations and the Malagassys have proved themselves in the French sur- veying work in Madagascar. The reconnaissance for the primary triangu- lation along the 98th meridian was completed to the Canadian border and a scheme was ex- tended eastward connecting this work with the triangulation of the Mississippi River Commission. The execution of the primary triangulation in the Dakotas and Texas was prosecuted at a rate which surpassed even the notable record which had already secured an enviable reputation for the geodetic operations along the 98th meridian, the total extension amounting to 300 miles (500 kilometers). An equal distinction must be accredited to similar work in California and Oregon whereon re- markable progress has been made in connect- ing the transcontinental are work with Puget Sound. The progress of the magnetic work is shown in detail in Appendix No. 3, which includes a table of results of the magnetic declinations, dip and intensity of force observed on land and sea during the year, this being supple- mented with full descriptions of the magnetic stations occupied and meridian lines observed. A new feature is the inclusion of the observa- tions of the three magnetic elements at sea by the Coast and Geodetic Survey vessels in the course of their regular surveying opera- tions. The paper is replete with matters of interest to the surveyor, the mariner, the geographer and the geologist. Thus compre- hensive examination has been made of certain locally disturbed areas, as for example, in Douglas Island, Alaska, in the region of the local magnetic pole found in 1900; and the completion of the magnetic survey of Louis- lana in cooperation with the state geological survey revealed interesting and important re- sults as regards both the magnetic distribution and the secular variation. The table contains the magnetic results at 384 land stations distributed over 24 states and territories and 2 foreign countries. The table of sea results contains 52 entries of magnetic declination, 34 dips and 32 values of the total intensity of the magnetic force in the Atlantic and in the Pacific Oceans. The 396 methods and instruments adopted for the sea work, which have thus far proved successful, are described in detail. In a general retro- spective consideration of the work of the past five years it is pointed out that in this period observations have been made at 1,636 stations of which about one eighth are points previously occupied by the survey and since used for observations to secure data for ascertaining the secular change of the magnetic elements. The work in about a dozen states has been practically completed except for special in- vestigations and secular change observations. During the year a bureau of international re- search in terrestrial magnetism has been created by the Carnegie Institution of Wash- ington, with the inspector of the magnetic work of the coast survey in charge as director, and the cooperation thus ensured is certain to prove extremely profitable in results. The determination of the longitude of Manila from San Francisco, thus completing the first longitude circuit of the earth, was one of the astronomical events of the year, and in Appendix No. 4 is a comprehensive illustrated report on the various instruments and opera- tions used in the undertaking with a com- parative résumé of the various links and re- sults from which the longitude of Manila had been determined from the westward. The generous cooperation of the Commercial Cable Company, through whose patriotic enterprise the work was made feasible, is gratefully ac- knowledged. The results of the determina- tions from the eastward and westward differ only by 08.006 or about 8.8 feet. The other results of this expedition are the determina- tions by the telegraphic method of the longi- tudes of Honolulu, and Midway and Guam Tslands. The third attempt at representing the tide for the world at large, the first having been made by Whewell and Airy and the second by Berghaus, is described in Appendix No. 5. The advancement in recent years of the gen- eral use of the harmonic analysis and the greatly improved tidal data that are now ob- tainable for such a great part of the globe coordinate to make a new presentation of this subject very opportune. The theoretical dis- SCIENCE. [N.S. Vou. XXI. No. 532. cussion of the problems involved, the wide range of data and authorities consulted and referred to, the graphic presentation of the cotidal lines, the results presented and the conclusions deduced make a most suggestive paper and one which will be highly interesting to all students of the subject. The results of the precise leveling operations for the year are published in Appendices Nos. 6 and 7, which submit them in a detail that makes them immediately available for the re- quirements of surveyors and engineers. These extend the precise level net, as previously pub- lished, six hundred miles to the westward, from Red Desert, Wyoming, to Owyhee in east- ern Idaho; and from Holland, Texas, two hundred miles southwest, to Seguin, Texas. An interesting feature is an account of the change in the manner of support for the level- ing rods, with the comparative discussion of the old and the new methods and the conse- quent confirmation of the importance of the new system. The account of operations submitted by the assistant in charge gives the story of the work of the various computing, drawing, engraving and chart divisions of the office, in which the results of the field work are discussed or pre- pared for the publications and charts wherein they are placed at the service of the public. A full account of the first recording transit micrometer devised for use in the telegraphic longitude determinations of the Coast and Geodetic Survey is submitted in Appendix No. 8, with an account of the exhaustive tests it was subjected to and a recapitulation of the results of experience with this form of instru- ment, mainly in Europe, during the last thir- teen years. The results of these experiments indicate that with the transit micrometer the accuracy of telegraphic longitudes may be considerably increased, if desirable, or the present standard of accuracy may be main- tained at much less cost than formerly. The results of all triangulation in California south of the latitude of Monterey Bay are printed in the concluding appendix in full, in- cluding descriptions of stations, as well as their latitudes and longitudes and the lengths and azimuths of the lines joining them. In | ie peel he Marcu 10, 1905.) compact and convenient form there is given aul the information in regard to this triangula- tion that is needed by an engineer or surveyor who wishes to utilize the results in controlling and checking surveys or in constructing maps or charts. The locations of more than 1,300 points are accurately fixed by this triangula- tion. The report, in addition to the details of the foregoing operations and results, contains a record of a wide range of important work for which the aid of a survey was sought because of the special training of its officers. The superintendent attended the Fourteenth Gen- eral Conference of the International Geodetic Association as delegate for the United States and maintained direction of the observatories at Gaithersburg, Maryland, and Ukiah, Cali- fornia, supported by the International Geo- detic Association for the purpose of measuring the variations of latitude; he was also detailed for duty in connection with the presentation of the case of the United States before the Alaska Boundary Tribunal being assisted by one of the officers of the survey. As commis- sioner of the United States he continued the work of remarking the boundary line between the United States and Canada from the Rocky Mountains westward, two of the officers of the survey being employed in the field; and as commissioner of the United States in the In- ternational Delimitation Commission he in- augurated the work of marking the boundary between Alaska and Canada, one of the parties being under the direction of an assistant of the survey. One officer continued on duty as a member of the Mississippi River Commis- sion. One officer having completed the field work of the survey of Mason and Dixon’s line, the boundary between Maryland and Penn- sylvania, was then detailed to prepare the maps and report showing the results of the work. Another officer, at the application of the municipal authorities, remained in charge of the triangulation of the Greater New York territory, and one representative of the survey in cooperation with the Louisiana Oyster Commission continued the survey of the natural oyster beds and reefs for the state of Louisiana. SCIENCE. O97 THE PRESERVATION OF AMERICAN ANTIQUITIES. At a joint meeting of the committees on preservation of American antiquities of the Archeological Institute of America and the American Anthropological Association, held at the Cosmos Club in Washington, on the evening of January 10, the subject of pending legislation was considered. It was decided that a memorandum should be prepared em- bodying such provisions from pending meas- ures, as in the judgment of the joint commit- tee should be incorporated into law, and the same presented to the House of Representa- tives’ Committee on Public Lands, with the request that a bill should be prepared by this committee based on these suggestions. Present: For the Archeological Institute of America, Dr. Seymour, Chairman, Dr. Put- nam, Mr. Holmes, Mr. Bowditch, Dr. Kelsey, Dr. Carroll; for the Anthropological Associa- tion, Mr. Holmes, Chairman, Dr. Putnam, Miss Fletcher, Professor Saville, Dr. Gordon, Mr. Culin, Dr. Kroeber, Mr. Hewett. The memorandum was submitted by the committee at the hearing before the Public Lands Committee on Wednesday, the eleventh. At the meeting of this committee held on the sixteenth instant it was ordered to strike out all except the enacting clause of S. 5603 (the act known as the Lodge-Rodenburg bill which passed the senate last April) and insert instead “an amendment in the form of a substitute”; said substitute being, with a few minor amendments, the memorandum prepared by the joint committe above referred to. The bill as reported back, referred to the House Calendar, and ordered printed, is as follows: Sec. 1. Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled: That for the purpose of preserving and protecting from despoliation the historie and prehistoric ruins, monuments, archeo- logical objects and other antiquities, on the public lands of the United States, all said historic and prehistoric ruins, monuments and other objects of antiquity are hereby placed under the care and custody of the Secretary of the Interior. Sec. 2. That the Secretary of the Interior may make temporary withdrawals of the land on 398 which such historic and prehistoric ruins, monu- ments, archeological. objects and other antiquities are located, including only the land necessary for the preservation of such ruins and antiquities, and may make permanent withdrawals of tracts of land on which are ruins and antiquities of especial importance, not exceeding six hundred and forty acres in any one place. See. 3. That the Secretary of the Interior be, and is hereby authorized to permit examinations, excavations and the gathering of objects of in- terest within such reservations by any institution either domestic or foreign which he may deem properly qualified to conduct such examinations, excavations or gatherings, subject to such rules and regulations as he may prescribe: Provided, That the examinations, excavations and gather- ings are undertaken for the benefit of some repu- table museum, university, college or other recog- nized scientific or educational institution with a view to increasing the knowledge of such objects, and that the gatherings shall be made for perman- ent preservation and not for commercial purposes. Sec. 4. That of all excavations and explorations made under a permit granted by the Secretary of the Interior, a proper written and photographic record with plans shall be made at stated periods, and transmitted for preservation to the United States National Museum. See. 5. That the Secretary of the Interior shall make and publish from time to time such rules and regulations as he shall deem expedient and necessary for the purpose of carrying out the provisions of this act. Sec. 6. That all persons who shall with- out permission appropriate, injure or destroy any public property therein, or injure or destroy any caves, ruins, or other works or objects of an- tiquity therein, or commit unauthorized injury or waste, in any form whatsoever, upon the lands or objects referred to in this act, or who shall violate any of the rules or regulations prescribed hereun- der, shall, upon conviction, be fined in a sum not more than five thousand dollars, or be imprisoned for a period not more than twelve months, or shall suffer both fine and imprisonment, in the discretion of the court.

Tue legislature of North Dakota has passed a comprehensive irrigation code which fol- lows closely the provisions of the suggested state irrigation code drawn up last summer by Mr. Morris Bien of the U. S. Reclamation Service. This is the first effective legislation on the subject in North Dakota, and will put irrigation investigation upon a well estab- lished and permanent basis, so that it is now possible to secure the exclusive services of a competent man as a state engineer. ‘The first state engineer, Professor E. F. Chandler, who began that work last season and has been carrying it on in addition to his work as resident hydrographer for the U. S. Geological Survey and to his regular duties in the state university, now transfers the office to Mr. A. L. Fellows, of Denver, Colo., who has been for the past two years district engineer for Colorado of the U. S. Reclamation Service, and who now under the new law is appointed by Governor Sarles state engineer of North Dakota.

Golumbia University in the Witn of Hew Bork Columbia University includes both a college and a university in the strict sense of the words. The college is Colum- oia College, founded in 1754 as King’s College. The university consists of the Faculties of Law, Medicine, Philosophy, Political Science, Pure Science and Applied Science. The point of contact between the college and the university is the senior year of the college, during which year students in the college pursue their studies, with the consent of the college faculty, under one or more of the faculties of the university. Barnard College, a college for women, is financially a separate corporation ; but educationally, is a part of the system of Columbia University. Teachers College, a professional school for teachers, is also, financially, a separate corporation; and also, educa- tionally, a part of the system of Columbia University. Each college and school is under the charge of its own faculty, except that the Schools of Mines, Chemistry, Engi- neering and Architecture are all under the charge of the Faculty of Applied Science. For the care and advancement of the general interests of the university educational system, as a whole, a Council has been established, which is representative of all the corporations concerned. I. THE COLLEGE. Columbia College offers a course of four years, leading to the degree of Bachelor of Arts. Candidates for admission to the college must be at least fifteen years of age, and pass an examination on prescribed subjects, the particulars con- cerning which may be found in the annual Circular of Information. Barnard College, founded in 1889, offers for women a course of four years, leading to the degree of Bachelor of Arts. Candidates for admission to the college must be at least fifteen years of age, and pass an examination on pre- scribed subjects, the particulars concerning which may be found in the annual Circular of Information. II. THE UNIVERSITY. In a technical sense, the Faculties of Law, Medicine, Philosophy, Political Science, Pure Science, and Applied Science, taken together constitute the university. These faculties offer advanced courses of study and investigation, respectively, in (@) private or municipal law, (b) medicine, (ec) philosophy, philology and letters, (d@) history, economics and public law, (e) mathematics and natural science, and (/) applied science. Courses of study under all of these facul- ties are open to members of the senior class in Columbia College. Certain courses under the non-professional facul- ties are open to women who have taken the first degree. These courses lead, through the Bachelor’s degree, to the university degrees of Master of Arts and Doctor of Phi- losophy. The degree of Master of Laws is also conferred for advanced work in law done under the Faculties of Law and Political Science together. III. THE PROFESSIONAL SCHOOLS. The faculties of Law, Medicine and Applied Science, con- duct respectively the professional schools of Law, Medicine, and Mines, Chemistry, Engineering and Architecture, to which students are admitted as candidates for professional degrees on terms prescribed by the faculties concerned. The faculty of Teachers College conducts professional courses for teachers, that lead to a diploma of the university. 1. The School of Law, established in 1858, offers a course of three years, in the principles and practice of i= and public law, leading to the degree of Bachelor of laws. 2. The College of Physicians and Surgeons, founded in 1807, offers a course of four years in the principles and practice of medicine and surgery, leading to the degree of Doctor ot Medicine. 3. The School ot Mines, founded in 1863, offers courses ot study, each of four years,leading to a professional degree, in mining engineering and in metallurgy. 4. The Schools of Chemistry, Engineering and Architect- ure, set off from the School of Mines in 1896,offer respect- ively,courses of study,each of four years,leading to an appro- priate professional degree, in analytical and applied chem- istry ; in civil, sanitary, electrical and mechanical engineer- ing; and in architecture. 5. Teachers College, founded in 1888 and chartered in 1889, was included in the University in 1898. It offers the fol- lowing course of study: (a) graduate courses leading to the Master’s and Doctor’s diplomas in the several departments of the College: (6) professional courses, each of two years, leading to the Bachelor’s diploma for Secondary Teaching, Elementary Teaching, Kindergarten, Domestic Art, Domes- tic Science, Fine Arts, Music and Manual Training ; (c) a col- legiate course of two years, which, if followed by a two- year professional course, leads to the degree of Bachelor of Science. Certain of its courses may be taken, without extra charge, by students of the University in partial fulfill- ment of the requirements for the degrees of Bachelor ot Arts, Master of Arts, and Doctor of Philosophy. The price of the University Catalogue is twenty-five cents postpaid. Detailed information regarding the work in any department will be furnished without charge upon applica- tion to the Secretary of Columbia University. New York. A HAPPY THOUGHT.

SCIENCE.—ADVERTISEMENTS. ill THE STORY OF THE FRENCH REVOLUTION in THE HISTORIANS’ HISTORY OF THE WORLD (Published by THE OUTLOOK, New York and: The History Association, London.) HE proper study of mankind is history. Withoutit you are unenlightened. But how can you study it in the universal sense. There are 400,000 histories in the Bibliotheque Nationale of France alone, 300,000 in the British Museum. 5,000 new ones are pub- lished yearly in the chief civilized countries. Today you are invited to read 28 volumes on the United States ; yesterday it was 17 volumes on the Tudor period in England. You do not know the elements of world-history without which you are ungrounded and narrow-minded. You have lacked a modern scholarly world-history. You are lost in a labyrinth of diverse books. THE HISTORIANS’ HISTORY OF THE WORLD comes to your rescue. We wish to send you without cost, one specimen volume to prove that the editors have discovered the only satis- factory scholarly method of presenting world-history. They present in the actual words of all the greatest historians and history makers who have ever lived, with original contributions from the most scholarly living writers. We will send you Volume XII. on France from 1715 to 1815, the period of the Revolu- tion because it is intensely interesting and instructive. We are sure it will give you seven even- ings at home of continuous intellectual profit and pleasure. Its 420,000 words include the best writings of 186 great or valuable authorities on French history. Two thirds of the book has been specially translated from the French. You start with a special essay by Professor Alfred Rambaud, the first living historian of France, explaining the exact causes of the Revolution. Presently you come to John Law’s ‘Mississippi Bubble ’’ and ‘‘ frenzied finance ’’ schemes, described by P. E. Levasseur. The Duc de St. Simon reveals the vileness of Louis XV’s court. The de Goucourts portray Madame de Pompadour and ‘‘ Cotollin I.’’ who cost 500,000 lives from Rossbach to Quebec. Many hundred passages of keenest interest treat of war, politics, American colonies, women, philosophy, literature. Then the Revolution.—‘‘ Night and Orcus burst forth. . . . A world destroyed and en- gulfed.’’ Here we can but notice at random odd striking passages—remember that the history is exhaustive, scientific, detailed, consecutive, coherent. M. Thiers, the leading French Statesman of the nineteenth century, writes of the Constituent Assembly and how poor Louis XVI. toyed with the Revolution, losing his own head, and how many others! In words of immortal vivid- ness Thomas Carlyle shows us the Bastile falling. You live through the Reign of Terror, the guillotine orgies, noyades and fusillade that cost at least 20,000 lives. The poet-statesman Lamartine depicts poor Charlotte Corday’s career and execution for killing Marat. Nobler phases are appreciated. France’s marvellous fight against all Europe is described by H. Carnot, son of ‘‘the organizer of victory.’’ Robes- pierre dragged with a broken jaw to the guillotine is the climax of the Terror. ‘© A whiff of grapeshot ’’ and Napoleon holds the stage. His victories from Rivoli to Fried- land are described by Henri Martin, Victor Duruy and many others. Then the debacle. The finest battle picture ever penned, Victor Hugo’s Waterloo, brings that catastrophe before your eyes, while industrious writers like Sir Archibald Alison, and Baron Jomini supply lacking de- tails. In short, this is the most complete and accurate, yet dramatic, presentation of the most | dramatic period in all modern history.

ALPHEUS SPRING PACKARD. ALPHEUS SPRING Packarp, for twenty- six years professor of zoology and geology in Brown University, died at Providence, February 14, 1905. He was born at Bruns- wick, Maine, February 19, 1831. His father, for whom he was named, was for over sixty years connected with the Bow- doin College faculty, and his grandfather, the Rev. Dr. Appleton, was one of the early presidents of the college. At the age of eighteen he entered Bow- doin and there came under the infiuence and instruction of the late Paul Ansel Chadbourne, who fostered and encouraged his natural inclination towards zoological work. Dr. Chadbourne at this time was also connected with Williams College and it was through him that Packard became a member of the Williams College expedi- tion of 1860 to Greenland and Labrador, with which he went only as far as Labrador, where he spent two months collecting, get- ting back to college in time for the studies of senior year. In the senior vacation he, with several other Bowdoin students, went on a dredging trip to the Bay of Fundy. Immediately after graduation in 1861 he accepted the position of entomologist to the newly established scientific survey of Maine and in this capacity he traveled through a large part of the northern wil- derness of the state. On this expedition he made the first discovery of Silurian fossils in the northern part of Maine and obtained material for several articles which were published in the first two reports of the survey. 402 He had now decided on his life work and after the season in the field, went to Cambridge to’ study with Agassiz. Here he devoted himself largely to the study of insects for the three years that he retained his connection with the Museum of Com- parative Zoology, but in his spare time he read medicine and each winter he attended the lectures in the Maine Medical School connected with Bowdoin, from which he was graduated with the degree of doctor of medicine in 1864. In the summer of that year he made a second trip to Labrador, where, with his enlarged experience, he was able to add greatly to the knowledge acquired on his former trip. As a result, besides several smaller papers, he published a large me- moir on the geology and zoology of that region. Later this material was worked over and formed the basis of his book on ‘The Labrador Coast.’ On his return from this second trip to Labrador he enlisted for three years as assistant surgeon and accompanied the first regiment of Maine Veteran Volunteers to Virginia, where he served until the end of the war. These ten months included the whole of his medical practise. After be- ing mustered out he acted for a time as librarian and custodian of the Boston So- ciety of Natural History, remaining there until 1866 when with several of his former fellow students—Hyatt, Morse, Putnam and Cooke—he accepted a position in the museum of the Essex Institute at Salem, at that time one of the most active scientific societies in the country. Then came the founding of the Peabody Academy of Science in Salem. To it the Essex Institute transferred its collections and the scientific corps went with them, Packard being appointed curator of inverte- brates and in 1876 director of the academy. Here he remained until 1878, when he ac- cepted the position at Brown which he held SCIENCE. [N.S. Vou. XXI. No. 533. for the rest of his life. While at Salem he held various other positions. He was for three years state entomologist of Massa- chusetts, lecturer for several years in ento- mology at the Amherst and Orono Agricul- tural Colleges, and for two or three years upon zoology and comparative anatomy at Bowdoin College. He also worked for two summers on the Bache and Blue Light, dredging for the U. S. Fish Commission in the Gulf of Maine. He was connected for a time with the Kentucky Geological Survey, when he made a zoological explo- ration of Mammoth Cave and laid the foundation of his later work on eave life. From 1875 to 1877 he was one of the zool- ogists of the U. S. Geological Survey under Hayden. In 1873 Agassiz inaugurated the Ander- son School of Natural History on the island of Penekese, the first summer school of biology in America. Here for two years Packard gave the instruction in insects and ecrustacea, and when with Agassiz’s death the school was given up, Packard started a similar but smaller summer labo- ratory at Salem under the auspices of the Peabody Academy of Science which he con- ducted until his removal to Providence. This work was later taken up by the late Professor Hyatt at Annisquam, Mass., and continued until the establishment of the Marine Biological Laboratory at Woods Hole. In 1876 he was appointed by the President a member of the U. S. Entomo- logical Commission which was to devise ways and means of checking the ravages of the Rocky Mountain locusts in the trans- Mississippi country. Later the scope of the commission, which lasted for five years, was enlarged so that it might deal with other insect pests. On this service he made two trips to the west, one taking him to the Pacifie coast. Besides these trips he spent the winter of 1869-70 in Florida, stopping on his re- Marcu 17, 1905.] turn at Beaufort, N. C., from which place he brought back large collections of inver- tebrates. The next winter he spent at Charleston, S. C., where he’studied the de- velopment of numerous marine inverte- brates and especially of the crustacea, and where he collected the tertiary molluscs made known by F. 8. Holmes. In 1872 he visited Europe, studying the collections of insects in the large museums and paying especial attention to Walker’s types of lepidoptera in the British Museum. In 1885 he visited Mexico and in 1898 again spent a year in Europe and northern. Africa. Dr. Packard was a most indefatigable worker, the list of papers which came from his pen being numbered by hundreds. Only a few of these can be mentioned here. His first article was upon the army worm and was published by the Maine Scientific Survey. The years at Cambridge were chiefly spent in study, but some of the notes then made were incorporated in numerous later works, although large numbers of ob- servations made in these early years re- mained unpublished at his death. His first large work was the monograph of the geo- metrid moths published by Hayden’s Sur- vey, and scarcely less imposing was his account of the Bombycide issued by the National Academy. His embryological work, which included studies on the devel- opment of the lower insects, appeared in the ‘Memoirs’ of the Peabody Academy of Science and in minor papers elsewhere, while his memoir on the development of the horseshoe crab remained for years the chief source of our knowledge of that in- teresting animal. This work was all done before the days of sections and was based entirely upon surface views and optical see- tions, a fact for which allowance should be made when his mistakes are recalled. His papers on the geology and natural history of Labrador and on the cave animals have SCIENCE. 403 already been alluded to. Possibly his best article was the ‘Monograph of the Phyllo- pod Crustacea’ published in the last report of Hayden’s Survey. Packard was possibly best known for, his text-books. The earliest of these was his ‘Guide to the Study of Insects,’ which for years served as the vade mecum of hun- dreds of budding entomologists. Then came his ‘Life Histories of Animals,’ which was the first attempt since the day of Agas- siz’s Lowell Institute lectures to summarize the facts of embryology, a work which was early superseded by Balfour’s admirable treatise. Then came his ‘Zoology,’ the first attempt to give American students a truly scientific text-book in which morphology and classification were given equal promi- nence. This was followed by several small- er and more elementary works for lower schools, some of which have had a large sale. Later came a second work on ento- mology, in which the morphological side of the subject was strongly emphasized. Packard, along with his friends Cope and Hyatt, must be regarded as one of the founders and chief supporters of the so- called Neo-Lamarckian school of evolution, and his writings in advocacy of these views are numerous. His studies in this direc- tion led him to study deeply the writings of Lamarck and later to bring together all the known facts in the life of this early apostle of evolution. In fact his second trip to Europe was largely for the purpose of ascertaining everything possible concern- ing the man. In speaking of Dr. Packard one should not forget the services he rendered to sci- ence as one of the founders and for twenty years as editor of the American Naturalist. Almost as soon as he reached Salem the magazine was launched and while one by one the other editors dropped out Packard remained in charge. In these days of nu- merous natural history magazines one can 404 hardly realize the boon the establishment of this journal was to the naturalists of the country, and few know its financial vicis- situdes and the sacrifices of its editor dur- ing its early days. Personally, Dr. Packard was one of the most companionable of men. He was al- ways ready to aid and assist the young in their natural history studies to the extent of his powers. He was critical of the lan- guage in which they clothed their facts and the pages of the Naturalist have profited by his revision. He rarely indulged in con- troversy, and although he could say sharp and eutting things, one may look in vain in his published works for any traces of polemics. Dr. Packard was married in 1867 to Elizabeth Derby, the daughter of the late Samuel B. Walcott, of Salem, who, with four children, one a rising naval architect, survives him. J. S. KInesiey. TurtTs CoLLEGE, MAss. ALPHEUS SPRING PACKARD.* I have not known Professor Packard as long, nor as intimately, as many of my col- leagues; and where they have spoken I should remain silent. Neither am I quali- fied to discuss his more immediate scientific work. I can, however, in response to the President’s suggestions, speak of him in the light in which one scientific man sees an- other, older and wiser than himself; but I do so with diffidence. I have, therefore, written down with some care the things which I would not otherwise venture to express. It seems an ungracious confession to make, but it is nevertheless true, that it was through Professor Packard that many of us in Washington, twenty or thirty years * Address given at the memorial exercises at Brown University. Printed in Science at the request of the editor. SCIENCE. [N.S. Vor. XXI. No. 533. ago, became aware of the existence of scien- tifie activity at, Brown University. For age had wearied the enthusiasm of Alexis Caswell twenty years earlier. Yet it was not by his presence that Packard repre- sented her; at least in the years in which I knew him, he was not a frequent attend- ant at scientific meetings remote from Providence. It was his untiring and re- markably pervasive industry that con- fronted us. The president of the National Academy, the director of the Geological Survey and others in authority all felt the force of it; and at one time there were dis- mal mutterings in the high places of legis- lation asking why the public printer’s time should be spent in bringing out the elab- orate researches of one who stood remote from public office. How did this come about? Certainly a man of Professor Packard’s singular modesty, of his almost morbid habit of self-depreciation, was the last to find his way through the mazes of a government lobby. His transparent sin- cerity would have been infinitely removed from all this. And yet there was no mys- tery about it. It was a mere force from within breaking its way. The power of Professor Packard’s intellect bearing on subjects of natural history, the scope and accuracy of his learning and the purity of his scientific ideals were his only resources; and wherever institutions needed the fruits of ripe scholarship to dignify their own scientific activities, these were the first to feel the influence of Professor Packard’s productive zeal, as they were compelled to guide its progress. And so our unobtru- sive colleague taxed the people of the whole United States to publish his magnificent memoirs—because he was genuine. The same facts appear in a different way, in the further story of Professor Packard’s life. I am the last man to speak lightly of the young vigor and the promise of our American institutions, or of our Marcu 17, 1905.] learned societies. But it is nevertheless true that in comparison with the famous academies of the old world we are as yet mere children. In a history of the essen- tials in the progress of science, there is but rare need of the mention of American ac- complishments. We have much of the practise, and we show a degree of inde- pendence in our imitations; but we lack the philosophic depth, the intuitions and the profound originality. It is to the law- giver of science that the true academy is born, and it is by her lawgivers again that it must be nurtured. To men of exquisite genius no climate within the whole range of our immense country has yet been con- genial. ‘ We are apt to smile at the Englishman for the letters which decorate his name. We laugh at the German for his titles and at the Frenchman for his ribbons and his uniform. We smile because to us such insignia mean nothing; and it is to our shame. We forget that these symbols voice a sentiment of almost religious purity. We have not yet learned to constitute nor even to revere a tribunal so august as to be in- compatible with pettiness. We never ask why the F.R.S. is inseparable from the names of Lord Kelvin, of Lord Lister, even in their age and amid the splendors of their glory. To make the French Academy, even on its scientific side, required: the brains of Cuvier, of Lamarck, of St. Hil- aire, of Buffon, of the brothers Jussieu, of Pasteur ; it required Laplace, Lavoisier and Lagrange, Carnot and Cauchy, Fresnel and Fourier, Ampére and Arago, Poisson and Poinsot, to mention only a few; and the dictum of the academy arbitrates with the authority of these tremendous names. Precisely to such bodies of inexorable eritics did the intrinsic strength of the work of Professor Packard ultimately ap- peal. And it was from the judgment of his confréres, from the men who had them- SCIENCE. 405 selves traversed the same intellectual terri- tory and knew it, that he reaped his su- preme honors. From these alone could the reward have come; for below the decisions of his peers, there was no other guide but conscience. Few of us realize how difficult it is, what persistent convictions, what sturdy vigil- ance is required to enter seriously into competition with the whole world, as Pack- ard did; indeed one might say to enter handicapped, against a world richer in its traditions, more refined in its higher intel- lectual atmosphere, more bountiful in its opportunities, than our young country. It takes courage to press forward alone, self- reliant, misunderstood, at peace only with one’s own convictions. Did we think of this in Packard’s case? Did we look at his Linnean and other honors in this hght? Did even our corporation feel that the cause of which it is the supreme guardian, had in Packard been awarded with the most cherished tokens of the world’s approval? Packard was not lacking in his reverence for art, for literature, for music; but his soul cried out for science. He felt instinet- ively that the handiwork of man, however sublime, can not be more than human; and that a finite brain has fashioned all its eul- tures. Nature is the offspring of omnis- cience. He realized what the world was so slow to realize, what only within the last few hundred years has come like a tumul- tuous awakening, that the universe was wrought in the workshops of God, and that she alone is ultimately divine. He felt too that her true poetry is not written in rhet- orie but in mathematics and in the stern logie of science. For all our natural phi- losophies are but an attempt at a picture. We find no adequate symbols in our efforts to restate her methods; our analogies, our metaphors, are gross; we have to shift, to approximate, to neglect. But nature neg- 406 lects nothing! To her the infinitely large and the infinitely small on the boundaries of which we live are alike finite among her infinities. Touch her at any point and your contact is with the eternal. To contemplate the prolific labors of Pro- fessor Packard is to stand face to face with the attributes of genius. I do not wish to make an over-statement. True, there is an order of genius among the geniuses, but there is none in whose heart the sacred fire does not burn. There can be no holier joy than the joy of creative work, and yet it is a joy akin to terror. What is it which pos- sesses a man even in early youth, which impels him despite all obstacles and re- straint to strive evermore, intellectually alone, without approval, profitlessly after an unattainable ideal; whose spell grows more potent as his years ripen, as his toil increases, as the world grows caustic in its rebuke; and that leaves him only with death? Do not suppose that the poet or the sculptor or the martyr alone have it. It burns to-day with subdued passion but with all its pristine and unmitigated fierce- ness in the life of every true student of nature. What is it that can sustain a man when every new avenue of thought discovered is but the approach to countless avenues be- yond; when to finish, be it after years of labor, is only to be ready to begin; what encourages him when the unknown looms with greater vastness as the known is more profoundly mastered; when the very pin- nacle of attainment is the sublime con- sciousness of ignorance, and when to be most renowned is to be most devoutly humble? It is the inspiration which il- lumined the life of our friend, our eol- league, our teacher. Long may his ideals guide us at Brown! Cari Barus. Brown UNIVERSITY. SCIENCE. [N.S. Vou. XXI.. No. 533. THE ASTRONOMICAL AND ASTROPHYSICAL SOCIETY OF AMERICA. Tue sixth meeting of the society was held December 27-30, 1904, at Philadel- phia, Pa., during convocation week, in affiliation with the American Association for the Advancement of Science. Three sessions of the society for the read- ing and discussion of papers and the trans- action of business were held in room 106, College Hall, University of Pennsylvania, on Wednesday, Thursday and Friday afternoons. The number of members pres- ent at some time during the meeting was thirty-six and the average attendance was about fifty. A pleasant social feature connected with the meeting was an informal dinner at the Hotel Walton, Thursday evening, at which twenty-six members and friends were pres- ent. Through the courtesy of Director Doolittle, a number of the members had the pleasure of examining the equipment of the Flower Observatory of the University of Pennsylvania at Upper Darby, and by the courtesy of Professor Snyder the ex- tensive astronomical equipment of the Philadelphia Observatory was inspected by a considerable party. During the meeting five new members were elected. The selection of a time and place for the next meeting was left open for future action by the council. The officers elected were: For 1905: President—Simon Newcomb. First Vice-President—George E. Hale. Second Vice-President—W, W. Campbell. Treasurer—C. L. Doolittle. For 1905-6: Councilors—W. S. Eichelberger, Ormond Stone. On account of the contemplated absence from the country of G. C. Comstock for the ereater part of the year 1905, W. S. Eichel- berger was elected by the council as acting secretary. Marcu 17, 1905.] W. 8S. Eichelberger and C. L. Doolittle represented the society in the council of the American Association for the Advance- ment of Science. By request of a committee of the Na- tional Academy of Sciences appointed to secure international cooperation in solar re- search, a committee from this society was appointed by the president during the preceding summer to cooperate with the committee of the National Academy. The council has made this a standing committee of the society. PAPERS PRESENTED. C. L. DoorirrLe: ‘The Constant of Aberration.’ JouHn F.

The Constant of Aberration: C. L. Doo- LITTLE. The systematic observation for variation of latitude was begun by the author De- cember 1, 1889. This work has been kept up with some interruptions since that time. In 1896 was begun at the Flower Observa- tory a series which it was proposed to con- tinue on a uniform plan for a period of seven years. This design was carried out with but little departure from the original program. Observation on this series was terminated December, 1906. Work is now in progress on a more com- prehensive plan, two instruments being em- ployed, viz., the 54-inch zenith telescope and the 8-inch Wharton reflex zenith tube. The close of the former series seems to mark the proper time for bringing together the values of aberration constant which have been obtained, and for combining them to form a mean which may be con- sidered final so far as may be shown by these observations. The different values found are as fol- lows: SAYRE OBSERVATORY, SoUTH BETHLEHEM, Date.

It has accordingly ‘been assigned the wt. 1, the four remaining walues being given the wt. 2. Combining according to these weights, we find for the mean, I wish this to be regarded as the defini- tive value of this constant as derived from the zenith telescope observations extending from December, 1889, to December, 1903. The Test of a Transit Micrometer: JoHN F.. Hayrorp. When, in connection with an astronom- ical transit as used for time observations, a transit micrometer and chronograph are substituted for a system of fixed lines in the diaphragm, a telegraphic key and a ehronograph, the observer is relieved of the necessity of operating the key at, or as soon as possible after, each of the several instants of transit of the star across the fixed lines. Instead; he is required simply to keep the star image bisected continuously iby the movable micrometer line during its progress across the field of view. In the new process of thought the element of time enters only in an indirect manner. Hence, with a transit micrometer the personal equation becomes so nearly zero, and its variation so nearly zero, that it is difficult to prove that they are not both absolutely zero. The personal equation is one of the most serious sources of error in all time determinations and determinations of right ascension. The destiny of the transit micrometer is to produce a decided increase in accuracy in this class of observations without inerease of effort or cost. ‘The observation of star transits by means “of a movable transit line was first suggested in 1865 by Director Carl Braun of the Kalocsa Observatory. He believed that it was necessary to have the movable line ‘driven by clockwork. He failed to con- struct a satisfactory apparatus. SCIENCE. [N.S. Von. XXI. No. 533. Repsold, the well-known instrument- maker, was the first to suggest in print, in 1889, that no elockwork is required. He constructed a hand-driven transit microm- eter with which excellent results were se- cured. The Prussian Geodetie Institute put the Repsold hand-driven transit micrometer into use on portable instruments in making telegraphic longitude determinations in 1891, and has continued its use to the pres- ent time. In all, it has been used in ten longitude determinations. Utilizing the published past experience with transit micrometers Mr. E. G. Fischer, chief of the Instrument Division, Coast and Geodetie Survey, designed and con- structed in the winter of 1903-4 the tran- sit micrometer which is before you, and which is adapted for use on the transits ordinarily used in longitude determina- tions. It is a hand-driven transit micrometer. It is so well designed and constructed that in the extensive tests, to which I will refer in a moment, it never required the slightest change in adjustment, not even of the pressure of the contact spring, and not a single record was ever lost on account of any failure of the transit micrometer to operate properly. A peculiar and important feature of this transit micrometer is an automatic switch which operates, without the slight- est attention from the observer, in such a manner that a record is made on the chronograph for the middle four turns of the field, and for those turns only. This positively identifies those four turns, keeps the chronograph sheet clear, and enables the observer to practise following the star dur- ing the earlier part of its transit without affecting the chronograph sheet in any way. In Mareh, April and May, 1904, this in- strument was tested by 75 time sets on 18 Marcu 17, 1905.] nights at the Coast and Geodetic Survey office. Sixteen observers took part in this test. The observers were purposely se- lected so as to include some with little or “no experience in any kind of observation, some with long experience in astronomic observations and in handling various in- struments of precision, and some of various erades between these two extremes. Two observers worked at the same time, observ- ing alternate stars, and thus obtaining a determination of their relative personal equation. One of the sixteen observers was in the test continuously, became thor- oughly accustomed to the instrument and method of observation, and served as an intermediary through which all the other observers could be compared with each other. The tests show that for a practised ob- server with such a transit micrometer, the total error for a star, including errors which are constant for all the records as well as the accidental errors of bisection, is nearly the same for stars of all declina- tions if expressed in angular measurement. This is what should be expected if the errors concerned are of the same nature as if the object pointed upon were stationary instead of moving. The accidental errors of bisection are nearly the same expressed in angular meas- ure for stars of all declinations up to 59°, and are probably somewhat less for stars of greater declination. This is an indi- cation that the accidental errors of bisec- tion are of the same nature as if the image pointed upon were stationary, the indica- tion being partly contradicted by the smaller errors for stars of declination ereater than 58°. Good observations can be secured at once with the transit micrometer without pre- vious practise. Practise simply reduces the accidental errors by about 25 per cent. I feel that I may speak with assurance on SCIENCE. 409 this topic, for each of the sixteen observers was foreed to begin observing on the first star that appeared in his field of view, with no previous experience whatever. This point is emphasized for the reason that I had been led to expect that long practise would be necessary before an ob- server could be sent to the field with a transit micrometer. ‘The accidental error of a single record with the transit microm- eter is about the same as that of a single record with a key. During the first half of the tests the driving heads were geared to make one turn in 28.4, when observing an equatorial star. During the last half of the tests the driving heads were geared to turn one half as fast, namely, one turn in 48.8. This ex- treme change in speed produced surpris- ingly little effect on the accuracy of the result. With this instrument the speed of 45.8 per turn, or possibly a slightly slower speed, is believed to be most favorable to accuracy. The tests show that the relative personal equation between any two observers with the transit micrometer is so small as to be masked by the accidental errors of observa- tion. This is equivalent to saying that it is probably less in every case than 8.05, and is, as a rule, much smaller than this. The relative personal equation with a transit micrometer is certainly not more than one tenth as large, upon an average, as with a key. This conclusion as to the relative personal equation applies to inexperienced as well as experienced observers. The literature of the transit micrometer shows abundant corroboration of these con- clusions as to the relative personal equa- tion. It is diffieult to detect constant or sys- tematie errors of any kind in transit mi- erometer observations. All the errors seem to belong to the accidental class. 410 This is far from being true of key observa- tions. The transit micrometer is about to be put into use in the regular longitude work of the Coast and Geodetic Survey. I predict, basing my prediction upon the general experience with transit micrometers as well as on these particular tests, that with a transit micrometer three nights of observations without an exchange of ob- servers will give as great accuracy as has been secured in the past from ten nights of observations with a key, including an exchange of observers. This is a predic- tion of which the truth cr falsity can only be proved conelusively by field experience. I rely upon such experience to be gained within the next five years to verify the prediction. I venture to predict also that the evi- dence in favor of the transit micrometer wil! accumulate to such an extent in the next ten years in fixed observatories, as well as with portable instruments, that the astronomer who uses a key in 1914 for accurate time determinations or determina- tions of right ascension will have difficulty in furnishing adequate explanation of his conduct. An illustrated description of the Coast and Geodetic Survey transit micrometer, with a full report of the tests referred to above, and a brief résumé of a part of the literature of the transit micrometer, is now being printed as an appendix to the Coast and Geodetic Survey Report for 1904. Remeasurement of the Hough Double Stars: Eric DoouiTt.e. The catalogues of new double stars pub- lished by Professor Hough comprise 622 pairs, of which 77 are closer than 3” and 143 closer than 1”; in those pairs in which the distance is greater than 5” the com- panion is usually excessively faint; in fact, there are few of the stars which would not SCIENCE. [N.S. Vou. XXI. No. 533. be difficult with a telescope of much less than 18 inches aperture. The measurement of this fine series of doubles seems to have been strangely neglected. On a few of them, which are of the type of close pairs of equal magni- tude, as 98, 260 and 296, there are a num- ber of rather discordant measures, but the creat majority have received no attention except from the discoverer himself. Thus there are but 87 pairs which have been measured in two different years, and on no less than 358 there is but a single prior measure. The entire list was, therefore, added to the observing list for the 18-inch refractor of the Flower Observatory. Thus far, 360 pairs have been measured on three or more nights and many of the remaining 262 are partially measured; a single night’s meas- ure consists in each case of at least four measures of position angle and four of the double distance. Change has been found in 16 of the close pairs, and among the wider ones there is in 33 instances indication of proper motion. It is the intention, when the work is com- pleted, to publish a catalogue of these stars, including about twenty new pairs which Professor Hough has discovered since his last list was issued. A Study of the Drwing-worms of Several Photographic Telescopes: Epwarp §. KING. In following a star with a photographie telescope we must have for the period of the exposure a clock the hour hand of which will indicate the elapsed time on a scale graduated to seconds or less. We must have the equivalent of being able to determine the time by measuring the posi- tion of the hour hand with a micrometer. If any periodic error occurs in the train of the driving mechanism, causing the tele- scope to be first in advance of, and then Marcu 17, 1905.] behind, its proper position, the stellar im- ages will be elongated into lines having a length dependent upon the amount of the oscillation. If the telescope follows the star only at one extremity of the oscilla- tion, we shall have a series of images sepa- rated by trails, or, if the rate of the tele- scope is changed more, we shall have a trail with dark knots appearing at regular inter- vals. The number of the knots determines the frequency of the oscillation, and almost invariably indicates the driving-worm or endless screw as the offending member. Such a periodie error, as shown by slide 1, is present in nearly all telescopes driven in this manner. This fact is not anything new, but has been recognized for years. The first example that I know of personally occurred in 1888 with the Boyden thirteen- inch telescope. In 1896 the director asked me to determine the periodic error of two of our photographic telescopes. Several series of measures were made of the eight-inch and the eleven-inch Draper telescopes. The method was to view a point of the tail-piece through a fixed mi- eroscope fitted with a micrometer. After each release of the detent by means of the signals given by hand, the position of the point was read and recorded. The reduc- tion of these measures shows that the oscil- lation for the eight-inch Draper telescope was about 1 second, and for the eleven-inch Draper telescope about 0.2 second. These figures correspond to trails of less than 0.01 em. on the plate. Within a few years Dr. Hartman has studied the periodic error of the Potsdam refractor and pro- vided a very ingenious method of correc- tion. o Marcu 17, 1905.] and zoological nomenclature, and that the use of a generic name in the one kingdom did not debar its use in the other. The dif- ferent branches of zoology have now become so extended and specialized that the same rule of divorce might well be extended to the dif- ferent branches of zoology. Little, if any, con- fusion could arise to ornithologists, or mam- malogists, or ichthyologists, if a bird name, a mammal name, or a fish name should have eurrency for a genus of insects, or mollusks, or crustaceans, or echinoderms, or in each of these branches. If it could be agreed—and I am aware of no opposition—that the same generic name may hold good in different branches of the animal kingdom, but must not be used twice in the same branch (as in vertebrates, for example), it would result in the restoration of not a few familiar names that have had to give way under the animal kingdom priority rule, and lessen, if not quite do away with the present incipient call for an impracticable ‘ one-letier rule.’ 5. The Authorily for Names.—lIt is diff- cult to see the reason for Canon X XIX., which appears not to be published in full in The Condor. It is contrary to current usage and to other modern codes, that the authority for a name, given in manuscript on a museum label, is to be cited as the proper authority for such names when published by another author, who supplies the description and as- sumes the responsibility for the species. This canon says: “If a writer ascribes one of his species to some one else, we must take his word for it. Thus the manuscript species of Kuhl and Van Hasselt in the Museum of Leyden, although printed by Cuvier and Valenciennes, should be ascribed to Kuhl and Van Hasselt.” This is not only a confusion of responsibility, but is bibliographically mis- leading, tending to throw the investigator off the track in looking for the original descrip- tion of the species. Unless the publishing author endorses the supposed new species, he simply ignores the manuscript name and takes the responsibility for its suppression, just as in the other case he takes the responsibility for its publication and supplies the necessary description. If the author of a manuscript SCIENCE. 435 name supplies a description to accompany it, which only rarely happens, and the publishing author uses it as inedited manuscript, then the author of the name is also the author of the deseription and is to be cited as the au- thority for the species. In the other case, the name should be eited, in synonyny, as Cuvier (ex Kuhl, MS.), and otherwise as simply Cuvier. In the case of inedited matter, the citation would be Kuhl (in Cuvier, ete.), and otherwise as Kuhl. This, like the other points eriticized above, is a singularly retrograde step. J. A. ALLEN. CURRENT NOTES ON METEOROLOGY. METEOROLOGICAL RESULTS OF THE BLUE HILL KITE WORK. Tue meteorological work done at the Blue Hill Observatory by: means of kites has so often been alluded to in these ‘ Notes’ that no comments on the value of this work are neces- sary at this time. The latest publication in this connection is a valuable report by H. H. Clayton, entitled ‘The Diurnal and Annual Periods of Temperature, Humidity and Wind Velocity up to Four Kilometers in the Free Air, and the Average Vertical Gradients of these Elements at Blue Hill’ (Annals Astron. Obs: Harv. Coll., UNIT. Pt. 1, 1904). Al- though some of the results herein discussed have already been brought forward in previous publications by Mr. Rotch and Mr. Clayton, the compact and careful summary now issued will be welcomed as giving a definite and com- plete presentation of the principal conclusions which have been reached through the well- known, extended and laborious series of scien- tifie kite flights—a field of investigation in which Blue Hill has taken a front rank. A study of the sources of error in the in- struments and methods precedes the discussion of the results. Six possible sources of con- stant error are recognized as influencing the records, and also one source of error, not con- stant, which arises from temporary local dif- ferences of condition, and from the fact that the kites do not rise vertically. A glance at these preliminary pages will show with what extreme care the observations have been treat- 434 ed before being employed in obtaining any definite results. of the sources of error must also bring up many doubts concerning the accuracy of re- sults obtained by observers who exercise less eare. It may be noted that, in Mr. Clayton’s opinion, the excessive temperature gradients, greatly exceeding the adiabatic rate, which have several times been referred to in various publications, are probably due, for the most part, to the fact that the observations in ques- tion were not made simultaneously at the two levels (p. 14). Temporary local differences of temperature may also explain gradients which exceed the adiabatic rate (p. 15). The interest which attaches to all reliable meteorological data obtained in the free air is’ so great as to warrant the inclusion, in the pages of Science, of the following summary of the most important points contained in Mr. Clayton’s report. Diurnal Period of Temperature at Different Heights—On several occasions observations were obtained during many hours at heights of about 3 kms., but there was no evidence of any change of temperature due to a diurnal period. On June 18-19, 1900, for example, the temperature at a height of 2,900 ms. was recorded at intervals throughout twenty-four hours, and although there was a general fall under the influence of some general atmos- pheric. change, there was no appreciable di- urnal period (Fig. 3, p. 16), in spite of the fact that there were only a few cirrus clouds to obscure a small portion of the sky. At 1 km. there is a diurnal period of tempera- ture, as is evidenced by numerous records, but with a tendency to a secondary maximum at night as well as by day. A marked feature is also a sudden fall of temperature after sun- rise (about 9 A.M. in summer), the evidence from the movements of the kites at this time being to the effect that the diurnal convec- tional currents from the ground reach the kites then. This ‘chilling’ of the air at a height of about 1 km. is explained by Mr. Clayton as due to the rise of the ascending currents, on account of their inertia, to an altitude greater than their point of equilib- rium. ‘The ascending air is cooled by adia- SCIENCE. Mr. Clayton’s thorough study - [N.S. Vou. XXI. No. 5332 patie expansion below the temperature of the air into which it penetrates; hence, at the tops of convectional currents of this kind, rising irom the ground, there ought to be a belt of chilled air, above which there must be a higher temperature. Such an inverted temperature gradient is usually found above cumulus clouds. The diurnal change of temperature at the greatest altitude reached by the ascend- ing currents must, therefore, be the opposite of that at the ground, z. e¢., the temperature is lower by day than by night. The records of May 1, 1902, show clearly that an inversion of tle march of the diurnal temperature does occur at the top of convectional currents rising from the warm ground (Fig. 4, p. 20), for while at 500 and 1,000 ms. the afternoon maxi- mum is well marked, the temperature curve becomes inverted at 1,230 ms. At 2,000 ms. there is no perceptible diurnal period. This cooling at the tops of convectional currents begins nearer the earth’s surface early in the 11orning, and reaches a maximum altitude about the warmest part of the day. The di- urnal period of temperature at different heights is graphically summarized in Fig. 5 (p. 25), and verbally, on p. 29. The Diurnal Period of Relative Humidity at Different Heights—In general, the diurnal period in relative humidity is the inverse of that of the temperature at all levels up to and including 1,500 meters. The Diurnal Period in Wind Velocity at Different Heights—Mr. Clayton finds the well-known explanation, given by Espy and Képpen, of the diurnal variation in wind velocity only a partial one, for at night the air from 300 to 1,000 ms. above sea level does not merely resume a velocity of movement proportional to its height, but increases in velocity until its movement is more rapid than that of the air strata above or below the given level. Some other forces must, in Mr. Clayton’s opinion, be called into play besides the retardation of the upper currents by as- — cending currents from below. It is suggested that, as the atmosphere is trying to maintain a mean yelocity of flow having a constant — value for the vertical section above any given ~ point on the earth, if in any given part of ; Marcu 17, 1905.] the section the velocity is diminished, the air must flow faster in some other portion. This theory seems to explain satisfactorily the in- creased velocity between 3800 and 700 ms. at night. The retardation of the air between 900 and 700 meters during the day, due to ascending currents, results in an increased velocity near the ground, and, as this is not sufficient compensation, also in the section of air between 1,000 and 2,000 meters. Hence, at the latter height, the velocity has a maxi- mum by day and a minimum by night, as is the case at the ground. Vertical Gradients of Temperature, Humid- ity and Wind Velocity—At night the tem- perature rises with increase of altitude up to about 500 meters, and not until a height of over 1,000 meters is reached is the tempera- ture in the free air as low as at the ground. During the day the temperature decreases with altitude nearly at the adiabatic rate for dry air up to 500 meters. Above that height the rate decreases, probably owing to frequent inverted gradients and to cloud formation. Between 500 and 1,500 meters the temperature decreases more rapidly by night than by day. The decrease is most rapid in summer and least in winter. During the day the rate of decrease diminishes to 2,000 meters, and then increases again. From 0 to 500 meters the rate is at a maximum by day and a minimum by night, but between 1,000 and 1,500 meters this condition is reversed, owing to the inver- sion of the diurnal period. An important point, noted on page 50, concerns the mean vertical temperature gradient, about which much has been written. Gradients which are the mean of two opposing conditions may not occur at all. The most frequent gradients which actually occur are (J.) an increase of temperature with increase of altitude, between +0°.1 and +1°.0 (C.) per 100 meters, and (II.) the adiabatic gradient, 1°.0 (C.) per 100 meters. Some gradients exceeding the adia- batie rate have been observed, chiefly between 9 a.M.-and 3. p.m. On the average, the rela- tive humidity increases during the day up to about 1,000 meters, and then decreases to about 2,500 meters. During the night the relative humidity diminishes rapidly up to a SCIENCE. 435 height of 500 meters, and then more slowly, to a height of about 2,500 meters. Above 2,500 meters the relative humidity increases slowly again. There is a very rapid increase of wind velocity at night to a maximum at 500 meters, a slight decrease between 500 and 1,000 meters, and then an increase becoming more rapid with increasing height. There is a relatively rapid increase of wind velocity by day from the ground to 500 meters; a slower decrease from 500 to 1,500 meters, and almost no change from 1,500 to 2,000 meters. R. DEC. Warp. MEETING OF THE BRITISH ASSOCIATION IN SOUTH AFRICA. Tue British Association will hold its meet- ing this year in South Africa. In these ex- ceptional circumstances, the general officers of the association requested the council to ap- point a strong committee to cooperate with them in carrying out the necessary arrange- ments. ‘This ‘South African Committee’ has held frequent sittings; and its work is so far advanced that the London Times is now able to make the following announcements: Although the annual circular and program have not yet been issued, pending the receipt of information from South Africa, many mem- bers have already intimated their intention of being present at the meeting. The ‘ official party’ of guests invited by the central execu- tive committee at Cape Town, and nominated in the first instance by the council of the association, numbers upwards of 150 persons, comprising members of the council, past and present general officers and sectional presi- dents, the present sectional officers, and a cer- tain proportion of the leading members of each section. To this list has yet to be added, on the nomination of the organizing committee, the names of representative foreign and colonial men of science, the total number of the official party being restricted to two hun- dred, including the local officials. It is hoped, however, that many other members of the asso- ciation will also attend the meeting. The presidents-elect of the various sections are as follows: 436 A. Mathematical and Physical Science.—Pro- fessor A. R. Forsyth, M.A., Se.D., F.R.S. B. Chemistry.—T. Beilby. C. Geology—Professor H. A. Miers, M.A., D.Sc., F.R.S. D. Zoology—G. A. Boulenger, F.R.S. E. Geography.—Admiral Sir W. J. L. Wharton, K.C.B., F.R.S. F. Economie Science and Statistics—Rev. W. Cunningham, D.D., D.Se. G. Engineering.—Colonel Sir Colin Scott-Mon- erieff, G.C.S.I., K.C.M.G., R.E. H. Anthropology—aA. C. Haddon, M.A., ScD., F.R.S. I. Physiology—Colonel D. Bruce, M.B., F.R.S. K. Botany.—Harold Wager, F.R.S. L. Educational Science—Sir Richard C. Jebb, Litt.D., M.P. The vice-president, recorders and secretaries of the eleven sections have also now been ap- pointed. In view of the numerous towns to be visited by the association, and in which lectures or addresses will be given, the number of lecturers appointed is much larger than usual. The list of these, as at present arranged, is as follows: Cape Town.—Professor Poulton, on Burchell’s work in South Africa; and Mr. C. V. Boys, on a subject in physics. Durban.—Mr. F. Soddy, on radioactivity. Maritzburg.—Professor Arnold, on compounds of steel. Johannesburg.—Professor Ayrton, on distribu- tion of power; Professor Porter, on mining; and Mr. G. W. Lamplugh, on the geology of the Victoria Falls. Pretoria (or possibly Bulawayo).—Mr. Shipley, on a subject in zoology. Bloemfontein.—Mr, Hinks, on a subject in as- tronomy. Kimberley.—Sir William Crookes, on diamonds. As the wish has been conveyed to the council from South Africa that a few competent in- vestigators should be selected to deliver ad- dresses dealing with local problems of which they possess special knowledge, a geologist, a bacteriologist and an archeologist have been invited to undertake this work, involving in two cases special missions in advance of the main party. Whilst Colonel Bruce, F.R.S., will deal with some bacteriological questions of practical importance to South Africa, Mr. ~ SCIENCE. [N.S. Vor. XXI. No. 533. G. W. Lamplugh (by the courtesy of the Board of Education) will be enabled to investigate certain features in the geology of the Victoria Falls, particularly as regards the origin and structure of the canon; and Mr. D. R. Mac- Iver, who is at present exploring in Nubia, will proceed in March to Rhodes in order to examine and report on the ancient ruins at Zimbabwe and also Inyanga. Most of the officials and other members of the association will leave Southampton on July 29 by the Union-Castle mail-steamer Saxon, and arrive at Cape Town on August 15, the opening day of the meeting; but a considerable number will start from South- ampton on the previous Saturday, either by the ordinary mail-boat or by the intermediate steamer sailing on that date. The sectional meetings will be held at Cape Town (three days) and Johannesburg (three days). Between the inaugural meeting at the former and the concluding meeting at the latter town opportunities will be offered to members to visit the Natal battlefields and other places of interest. Subsequently a party will be made up to proceed to the Victoria Falls, Zambesi; and, should a sufficient num- ber of members register their names, a special steamer will be chartered for the voyage home, via Beira, by the East Coast route, as an alter- native to the return through Cape Town by the West Coast route. Thus all the colonies and Rhodesia will be visited by the associa- tion. The tour will last seventy days via Cape Town, or a week longer vid Beira (all sea), leaving Southampton on July 29, and re- turning thither on October 7 or 14. A central executive committee has been con- stituted at Cape Town, with Sir David Gill as chairman and Dr. Gilchrist as secretary, while local committees have been formed at Johannesburg and other important centers. Professor G. H. Darwin, F.R.S., is the president-elect ; and among the vice-presidents- elect are the following: The Right Hon. Lord Milner, the Hon. Sir Walter Hely-Hutchinson, Sir Henry McCallum, the Hon. Sir Arthur Lawley, Sir H. J. Goold-Adams, Sir David Gill and Sir Charles Metealfe. Sir David Gill, Mr. Theodore Reunert and 4 Marcu 17, 1905.] others have taken a prominent part in the initial work. The South African Association for the Advancement of Science is cordially cooperating in the local organization, and will join with the British Association in attending the meeting. The aim of the council has been to secure the attendance of a representative body of British men of science, including specialists in various lines of investigation; and that, along with the generous support of the people and authorities in South Africa, should go far to insure the success of the meeting and to stimulate local scientific interest and research.

Mr. Matcotm Morris was expected to de- liver the Harveian lecture before the Harveian Society of London on March 9, the subject being some modern therapeutic methods in dermatology, with exhibition of cases treated by the X and Finsen rays. Dr. Davin Murray, professor of mathe- matics and astronomy at Rutgers College from 1863 to 1873 and subsequently adviser to the imperial minister of education at Japan and secretary of the board of regents of the Uni- versity of the State of New York, died on March 2, aged seventy-five years. Dr. Aucust BorntRAGErR, associate professor of chemistry at Heidelberg, has died at the age of eighty-five years. Harvarp Universiry and New York Uni- versity again unite with the Bermuda Natural History Society in inviting zoologists and botanists to spend six weeks in the temporary biological station located, as during the past two years, at the Flatts, Bermuda. It is ex- pected that the date of sailing from New York will be July 1. Those who desire to take ad- vantage of the opportunities offered by the station should send applications as early as possible, and not later than May 1, either to Professor E. L. Mark, 109 Irving Street, Cam- bridge, Mass., or to Professor ©. L. Bristol, New York University, University Heights, New York City. Tue Albatross, of the Bureau of Fisheries, has returned to California after four months of deep sea explorations of the South Pacific, under the direction of Mr. Alexander Agassiz. Tue forestry department of the University of Michigan, through the kindness of Dean O. Worcester, secretary of the interior, Philip- pine Islands, who was a graduate of the uni- versity in 1889, has received a collection of herbarium specimens of the forest flora of the islands, which will form study material and assist in preparing some of the students of the forestry department for the Philippine Service. Aw expedition from Indiana University, in charge of John A. Miller, professor of me- chanics and astronomy, and W. A. Cogshall, SCIENCE. 439 assistant professor of astronomy, will go to Spain to observe the total solar eclipse that occurs on August 80. At some point in north- eastern Spain, on a favorable site chosen by Professor A. F. Kuersteiner, of the depart- ment of romance languages, who is now in Spain, they will install their instruments. This temporary observatory will include a horizontal photographic telescope about sev- enty-five feet long, having an aperture of eight inches. Into this telescope the sun’s rays will be reflected by a mirror moving at such a rate that it will reflect rays in a con- stant direction. This telescope, with one ex- ception, will have greater photographic efii- ciency than any telescope that has hitherto been used to photograph the sun during a total solar eclipse, and is designed to secure photo- graphs of the corona on a very large scale. Fietp CotumsBiAN Museum, Chicago, has ar- ranged a course of nine lectures upon science and travel, on Saturday afternoons in March and April, at three o’clock, as follows: March 4.—‘ The Explanation of Indian Cere- monies,’ Dr. G.

Littlefield, of Pawtucket, R. I., Brown University becomes the recipient of the bulk of the Littlefield estate, estimated at $500,000. The will provides that the cor- poration shall apply the money as it sees fit, except that $100,000 shall be used for the establishment of the George L. Littlefield pro- fessorship of American history. By the will of William F. Milton, of New York, his estate will go to Harvard University on the death of Mrs. Milton. The daily papers state that it is worth between one and two million dollars. Cotumpra University has recéived $100,000 from Mr. Jacob H. Schiff to endow a chair of social work, and the new professorship has been filled by the appointment of Dr. Edward T. Devine, general secretary of the Charity Organization Society, director of the School of Philanthropy and editor of Charities. This endowment makes possible the close affiliation between the School of Philanthropy and Co- lumbia University. THE contest of the will of Mrs. Josephine L. Newcomb, who left more than $2,000,000 for the endowment of a college for women in connection with Tulane University, New Or- leans, has so far resulted favorably to the interests of the college. THE regents of the University of Nebraska have recently voted $50,000 for the erection of the first wing of a building to accommodate the department of geology and the State Mu- seum. The condition of the’ department at present is so overcrowded and is so subject to loss by fire that the curator has boxed and removed fifty tons of material during the past school year. This has been lowered for safe keeping in an unused steam tunnel running under the campus. In the hope and full ex- pectation that the legislature of Nebraska will act favorably upon this recommendation of the regents, the Honorable Charles H. Morrill, founder and patron of the Morrill geological expeditions of the University of Nebraska, has offered the department an additional thousand dollars annually with which to pursue geolog- ical investigations both within and beyond the SCIENCE. 7 (N.S.

This will make it pos- sible for the first time in several years to again resume the annual Morrill geological expedi- tions which were so fruitful of results from 1891 to 1901. WituiaMs CoLuece will ultimately receive $12,500 by the will of Mrs. Harriet A. Jones, of Chicago. Mr. E. Wuittey has given $5,000 towards the endowment of a chair of pathology at Oxford. THe Cambridge University convocation has voted to retain compulsory Greek in the ‘ little go’ or entrance examination, the vote being 1559 to 1052. It is understood that a ma- jority of the resident teachers preferred to make Greek optional, but the vote of convoca- tion is largely decided by the country clergy who have qualified for the M.A. Dr. E. O. Lovert, professor of mathematics of Princeton University, has been elected pro- fessor of astronomy to succeed Dr. C. A. Young, who has become professor emeritus. Mr. Harotp L. Mapison has been appointed instructor in zoology in Brown University. Dr. C. S. Gacer, assistant in the. labora- tories of the New York Botanical Garden, is acting as instructor in botany at Rutgers Col- lege for the last half of the collegiate year. Mrs. CorNnELIus STEVENSON, president, and several other members of the board of man- agers of the Free Museum of Science and Art of the University of Pennsylvania have re- signed owing to friction connected with crit- icism of some of the discoveries of Professor Herman V. Hilprecht. Dr. CuHartes G. Rockwoop, Jr., professor of mathematics at Princeton University, has resigned. Dr. Sportiswoop—E CAMERON has been ap- pointed professor of public health at Leeds. Dr. A. R. Cuseny, of the University of Michigan, has been appointed professor of pharmacology and -materia medica in Uni- versity College, London. Proressor L. V.

Section H of the American Association for the Advancement of Science held its regular sessions at the fifty-fourth meeting of the association, which was in progress in Philadelphia, Pa., during convocation week. The American Anthropological As- sociation and the American Folk Lore So- ciety affiliated with Section H. The officers for the meeting were as fol- lows: Vice-President—Walter Hough. Secretary—George H. Pepper. Member of Council—C. B. Moore. Sectional Committee—M. H. Saville, vice-presi- dent, 1904; George H. Pepper, secretary, 1904; Walter Hough, vice-president, 1905; George H.

Officers of the American Folk Lore Society— President, George A. Dorsey in the absence of George Lyman Kittredge. Secretary, W. W. Newell. The address of the retiring vice-presi- dent of Section H, Marshall H. Saville, entitled ‘Mexican and Central American Archeology,’ was delivered Friday after- noon. WEDNESDAY, DECEMBER 28. The afternoon session began with the paper on ‘Anthropometric Work at the St. Louis Exposition: (a) Sense Tests of Vari- 442 ous Races, (b) Physical Measurements of Philippine Groups,’ by R. 8. Woodworth and Frank G. Bruner. Over a thousand individuals, belonging to twenty-two groups and nine races, were measured, and most of these were subjected also to sensory and mental tests. Among the results may be mentioned: the superi- ority of some groups, especially the Fili- pino, in eyesight, and the inferiority of others, the Ainu, Negrito and African pigmy ; the presence of red-green blindness among Filipinos to about the same extent as among whites; the general inferiority of other. races to the white in fineness of color perception, but no special deficiency in per- ception of the violet end of the spectrum. A comparison of the height, cephalic, facial and other indices of several Filipino groups was obtained which showed that, on the whole, the population of the islands is remarkably uniform in physical measure- ments. After the presentation of Professor Woodworth’s paper, the society adjourned to attend the discussion on ‘Mutation Theory of Evolution,’ in Dental Hall. THURSDAY, DECEMBER 29. The meeting was opened by the vice- president, Walter Hough. The first paper was, ‘The Story of a Shield,’ by James Mooney. Professor Mooney said in part: In the old days all men between twenty- five and fifty years of age, in the Kiowa tribe, had shields. They were the personal property of the mounted warriors and, on the plains, this object was the most prized possession of the Indians. When a warrior was killed his shield was usually buried with him. Each shield had a distinct origin, although a number might be made of the same form and from the same dream. Out of 300 Kiowa shields there might have SCIENCE. [N.S. Vor. XXI. No. 534. been 50 shield origins. One man might make many shields, which came from a dream, and the wearers would form a small elan-like body. One of the old shields was that of the buffalo. Its origin was from the buffalo and it had buffalo medicine. It was worn by the medicine men who knew how to eure arrow and gun-shot wounds. As shields were used in warfare, they could be made for no other purpose. The bird shield was of special interest to the speaker, as he had been more closely associated with it than with any other. A story was related of a Kiowa boy who en- deavored to get medicine from a water monster formed like a horned alligator. He approached a pool and looked into the water. He heard the voice of a boy who finally invited him to his father’s tent. The young man went in. He saw seven men seated against the wall of the tent. These men turned into birds. Each had a shield which was fastened above his head. They told the young man that they had heard his longings and that they would give him medicine. They would give him a shield. They also gave him nine songs. The shrike gave him the song that was to be sung when he went into battle. The call of each bird was to be used in battle in connection with the proper shield and accompanying the song of the particular bird. A model of the original bird shield was shown. It had a rainbow, the sunlight and dots representing the ashes thrown down by the old men in the sky. These objects were considered to be great medicine. The inside of the shield contained the secret medicine known only to the owner. This was revealed at the moment that the owner made a charge in battle. Each shield had a number of taboos, the breaking of which was a misfortune; there were, however, many ways of propitiation and thereby overcoming the harm that had been done. Marcu 24, 1905.] Themistology. Epwarp LInpsay. An important branch of the study of man is the science of institutions. Of hu- man institutions one of the most important is law. Law has been defined as any re- straint of the individual by the group which is backed by physical force. This overlooks the idea of rules for the adjust- ment between individuals of the rights in- hering in them by reason of their status in the social organization, which are the ereater part of law. Different terms for these two concepts are needed; the first may be called Nomos, the second Themis. The science of themistology would investi- gate that portion of the law of all peoples embraced within the concept Themis. Eth- nologists have determined that there are various forms of social organization which have existed at different periods and among widely separated groups, and from the study of these have distinguished succes- sive stages in the evolution of society. In the same way we should examine other themal concepts, as marriage in its various forms, contract, ete., and, after collecting all available facts, study them and deter- mine whether there are ideas recurring generally among different groups which pass through a stated course of develop- ment. By this use of the scientific method may be obtained a true science of law. This subject is urged on the attention of anthropologists because the facts must be largely collected among primitive peoples. To distinguish between the two different classes of facts included under the term law, however, is essential to an intelligent collecting of material. Recent Investigations in the Somatic An- thropology of the Brain of Distinguished Persons, of Indwiduals of Various Races and of Criminals. Epwarp ANTHONY SPITZKA. A discussion of the doctrine of cerebral localization, of the significance of brain- SCIENCE. 443 weight and of surface morphology in their relations to the intellect and to race, and of the question of brain-heredity.

In the report of the author’s studies on the brains of notable men (eleven in all) some interest- ing results concerning the weight of the brain, the ‘concept area,’ the cerebro-cere- bellar ratio and the redundancy of the eal- losum were presented in detail.

Newell ealled attention to the presence of Miss Mary Speers, a lady who had collected negro songs. He asked that she be allowed to sing some of these southern melodies. In preparing these songs she demonstrated the need of study- ing the tone of the singer-as well as the notes of the song. Four selections were rendered. Superstitions of School Children. Win S. Monroe. Mr. Monroe has been collecting the su- perstitions and games of children for sey- eral years. One thousand children were questioned concerning good and bad luck. The predominating good luck charm among the girls was a pin; among the boys, a horseshoe. The number of superstitions among the members of both sexes at differ- ent ages were noted and tabulated. These consisted of arrival of company supersti- tions of which there were twenty-three; those concerning the weather, love and marriage, sickness and death, and the num- ber thirteen. He found that the thirteen superstition does not figure to any extent and was not found in children under ten years of age. The Tale of Three Wishes. Wiu1amM W. NEWELL. A negro story of a man who had three wishes. One should have been for salva- tion. Other wishes are made and he is given to the devil. When he is being ear- ried away he begs the devil to pick a pear for him. He is so insistent that the devil finally climbs the tree to obtain the fruit. One of the wishes that the man had made was to the effect that any one caught steal- ing his fruit would have to stay in the tree; thus he had the devil in his power. A second time he gets the devil into his purse es ————= Ra Marcu 24, 1905.] in the form of a'ten-cent piece. In thus using his wishes the man succeeded in keep- ing out of hell. This tale was compared with other wish- stories in which similar details appear. Influence of the Sun on the People of the Hopi Pueblos. J. WAuTER. FEWKES. The epitome of the history of the Pueblos is shown by their ruins. The earliest forms were on the plains. The second period brought them to the base of the mesas, the third and last to the level tops of the table lands. The inclination of the house groups on the mesa tops is in two directions—toward the highest point, to obtain the greatest security possible, and on exposures where the maximum sunlight may be obtained. The houses ofttimes form two lines, the direction being northeast and southwest. This peculiarity was first noted by Cosmos Mindeleff. The reason for this uniformity was not estheticism but the position of the sun. This occurs in all of the Hopi Pueb- los but two. There are three specific causes for this: (1) the growth of the family, (2) the growth of the house group, (3) the position of the sun. Among the Pueblos there are only two places where additions to the paternal home can be made, that is on the northeast and southwest of the nucleus or home group. The reason for this is that the additions must not cut off the sun from the house already built. These additions to the home continue as daughters are born and marry. When a new clan comes to a pueblo it is given a new position which will not conflict with the sun supply of the first group. The growth of these clan houses is a cel- lular one in which the family is the initial cell. This explains the form of most of the modern pueblos. Some of these are rectangular, which is the form of many of SCIENCE. 4405 the old ones. This may be explained by the fact that a number of clans partici- pated in the work of buwilding—both in planning and in earrying out the details of construction, in which ease the form of the town was probably prearranged. Even in this form of pueblo the terraces and door entrances were usually toward the sun. The clans have been a great factor in the formation of the house groups. They are responsible for whatever peculiar features may be in evidence in both the ancient and the modern pueblos. The clan problem is a most interesting one. Its solution can be accomplished in no way save by a thorough study of the migrations cf-each, and its relationship to the pueblo. It is one of the most interesting phases of anthro-geog- raphy or psycho-geography in the scuth- west. The Work of the Unwersity of California. ALFRED L. KROEBER. A general résumé of the anthropological work done by the university was given. Results of former expeditions were pointed out and the present policy cf the depart- ment outlined. Work is being carried on in Peru by Dr. Uhle; in California, espe- cially among the Hupa, by Dr. Goddard, and linguistic and general ethnological work in the same state by Dr. Kroeber. These investigations are under the direc- tion of the departmental head, Professor KF, W. Putnam. FRIDAY, DECEMBER 30. Historic and Prehistoric Ruins Southwest. Epaar L. Hrewert. Professor Hewett has devoted several years to the study of the remains of the old sedentary tribes of the southwest. He has mapped large groups and presented data to the department of the interior in an en- deavor to have certain areas containing ruins set aside as national parks. of the 446 His latest work has been the preparation of changes in and amendments to the bills that have been drawn up for the protec- tion of remains on the public domain. This work enabled Professor Hewett to handle the subject in a very comprehensible way. The groups of ruins were described, the labor expended .in each, and what should be done in the way of preserving them for future scientific work. The various bills for the preservation of ruins were ex- plained, and the objectionable features of each pointed out. Reports of the commis- sioner of the general land office, and a monograph by the speaker were given to members of the section in order that a bet- ter comprehension of existing conditions might be obtained. The Election at Jemez Pueblo. B. REAGAN. Read by title. ALBERT Prehistoric Surgery: A Neolithic Survival. GEORGE GRANT MacCurpy. This paper dealt with a certain type of neolithic surgery having certain points in common with trepanning, and which has been brought to light during the past decade. The type oceurs in France over a limited area lying to the north of Paris between the Seine and the Oise. The ci- catrice is usually in the shape of a T, the antero-posterior branch following the line of the sagittal suture; and the transverse branch, encountered in the region of the obelion, descending on either side to a point back of the parietal protuberances. In addition to the T-shaped lesion, one skull was marked by two oval perforations, one quite large, and two pits large enough to lodge the tip of the finger. The eight or nine specimens already described are all from prehistoric sepultures known as dol- mens. In the opinion of Professor Man- ouvrier the lesions were produced by cau- terization, an opinion which was recently SCIENCE. [N.S. Vor. XXI.

SECTION I, SOCIAL AND ECONOMIC SCIENCE. Section I is in some respects ideally con- stituted. It has a smaller body of experts in its membership who plan its programs and work out its policy. The larger num- ber of members represent business experi- ence and practical social effort. It thus combines in its programs the scientifie dis- cussion and methods of the expert with the results of well-considered experience in social and economic affairs. This year’s program was well supplied with papers: representing both phases of interest. Two joint sessions were held, one with — Section D for hearing a paper by Professor — A. E. Outerbridge, Jr., on ‘Specialization in Manufactures,’ and one with the Society for the Promotion of Agricultural Science, to hear the memorial by Professor W. R. Lazenby on the life of the late Major H. E. Marcu 24, 1905.] Alvord, of the U. S. Department of Agri- culture. The record of attendance of speakers on the published program was one of the best in the history of the section. Out of the twenty-three papers twenty were read in person by the authors. The attendance on the part of the public varied from thirty- five at the first session to seventy-five at the last session. Five different sessions were held, including one afternoon session de- voted to the address of the retiring vice- president, Professor Simeon E. Baldwin, New Haven, Conn., on ‘The Modern Droit D’Aubaine,’ treating of the recent multi- plication of succession tax laws, and their application to non-residents, resulting in double taxation. The following officers were elected : Vice-President and Chairman.—Professor Ir- ving Fisher, Yale University. Council—Marcus Benjamin. Sectional Committee—H. L. Corthell. General Committee—Henry Farquhar. The papers presented included the fol- lowing as reported in abstract: SESSION ON ECONOMIC QUESTIONS. The Basis of Economics as an Exact Science. Professor Srimon NEWwcoMB, Washington, D. C. One of the first things to strike us in the effort to apply scientific methods to eco- nomics is the absence of nomenclature. We notice, in the first place, that there is no name for the organized system of economic phenomena. Herbert Spencer has used the term ‘social organism,’ but the objection to that is that it includes more than is neces- sary. It embraces all phenomena which are social, but there are social phenomena which do not strictly belong to the economic order or which relate so indirectly to it as to be negligible factors in the consideration of economic questions. Another phase of defective definition SCIENCE. 447 may be mentioned. I refer to the fact that there is no name for that portion of wealth which is not capital. Marshall makes use of the inconvenient term of ‘wealth of the first order.’ Referring to the economic order as a whole, we notice, to begin with, that it is a unified system, in which the parts are re- lated as means and ends. In economies these terms, means and ends, take the place of the correlated terms cause and effect in the physical order. That is, the relation of means and ends in economics corresponds to the relation of cause and effect in phys- ics. In the economic order capital is means. The problem, then, is to find the relation of capital means to economic ends. We must study from ends to means and from means to ends according as the one or the other inquiry may be necessary to establish the causal relation which is the business of science to ascertain. Now, as to the method of inquiry. In this procedure we haye to distinguish be- tween machinery which is necessary for production and auxiliary means to an end. The machinery necessary for production is, of course, capital in its essential character. The auxiliary means to ends which capital serves to reach is money. But money, im- portant as it is in its auxiliary function, adds nothing to the power of the machine. Knowledge or direction is needed as an- other auxiliary in the organization of the means to ends of production. Socialism overlooks the necessity for the means of production, and seems to be based on the omission of this mediating factor between man’s wants and his ends. The socialist is like the man who walks to the edge of a precipice and propeses to proceed even at the risk of losing his hfe rather than to build a bridge to pass from one precipice to another. How far can economics be made an ex- 448 act science? It is often said that this sub- ject depends too much on the vagaries of human nature to bring the economic proec- esses within the category of exactness, This is true to some extent. We all know that the corn and the cotton crops, for instance, are uncertain quantities. We know that these affect economic activities to such an extent as to require constant readjustment. On the other hand, it is true that we know just about how a shortage in the corn crop or a marked enlargement in the cotton crop is going to affect the actions of persons interested. We know how the economic order in general, and how the divisions of enterprises directly affected are going to behave, other things being equal, under the changed conditions in the crop yield. It may, therefore, be said that there is a far greater degree of exactness attainable in measuring the force of eco- nomie processess than is usually assumed in the criticism based upon the assumptions of the vagaries of human nature. We may, therefore, be exact in the in- vestigation of the action of causes. For example, we can study with a remarkable degree of accuracy the influence of the in- crease of currency upon prices. We may also maxe the comparative con- dition of the masses in different countries a subject of exact study. Take the five different nationalities of Russia, Austria, France, England and the United States. These are given in the order of the wage income, let us assume. The cost of sub- sistence is about the same in all of them, but wages are lower in the order given. Why is this the case? There must be some exact causes, and the problem is to deter- mine what these laws are. Another phase of the subject of method on the action of causes appears in the ap- plication of mathematical methods or prin- ciples to the study of economies. Jevons, for instance, applied mathematical methods SCIENCE. (N.S. Vou. XXI. No. 534. to the determination of the law of marginal utility thirty or more years ago, and the principle has been extensively used and developed in numerous treatises since then. The law of supply and demand has like- wise been treated mathematically by Mar- shall. - Returning again to the study of the con- dition of the masses, the main question is to find the causes of inequality of income. Methods hitherto pursued have generally lacked comprehensiveness. We may, how- ever, assume that these inequalities are de- termined by the law of supply and demand and by a law of distribution growing out of the law of supply and demand. One of the first things we notice is the creat difference in apparently similar men. The captain of an Atlantie liner, for in- stance, who has millions of dollars of value intrusted to his care, together with thou- sands of lives, may in all outward respects and in mental qualities be apparently the equal of one whose judgment and practical capacity could in no wise be intrusted with so responsible a task as that of bringing a vessel across the Atlantic in safety. The first problem which we may propose for ourselves in this field is that of the effect of supply and demand on the distri- bution of income. In books three and four of my ‘Principles of Political Economy,’ published twenty years ago, I sought to work out this problem in its twofold as- pects: (1) From the standpoint of the — productive process, and (2) from the standpoint of the societary circulation or the monetary movement. The chief diffi- culty in the solution of this problem lies in the numerous complications of the eco- nomic order as represented in changes and the multifarious causes at work. The problem may be simplified in statement by being represented in graphical form. We may, for instance, take the loaf of bread as a product and follow it back Marcu 24, 1905.) through the chain of incipient factors, be- ginning with the farm on which the wheat is produced as the first step; second, Chi- cago as a wheat market; third, the baker; fourth, the house of the consumer. The productive process may be said to termi- - nate, temporarily, at any rate, in the house, extending from the farm of the producer to the house of the consumer. On the con- trary, the societary process, or the mone- tary flow, extends from the house of the consumer back through the baker and through the wheat market to the farm where production began. These two cur- rents represent an exact quantity, in the one ease of goods, and in the other ease of money. They move in opposing direc- tions, and in this respect are analogous to the two opposing currents acting simul- taneously, as represented in electrical theory. There are various other causal factors to be brought into the study of this relation, ineluding such factors as the mechanic, who purchases from the hardware store, the hardware store purchasing from the tool factory, the tool shop purchasing from the rolling mill, and the rolling mill from the mine; but along each of those connections the two currents, productive and cireula- tory, are in active operation, and all of these factors are directly or indirectly con- nected with another factor—the govern- ment. This representation may seem at first glance to be complicated by reason of the numerous currents represented in the two- fold process, the productive and the circu- latory. Could the conclusions arrived at in this method be put in such a form as to have the community accept them? Eeo- nomic conclusions are not easily accepted by the community in general. Why is this so? One reason—possibly the main rea- son—is that economists have failed to dis- tinguish between means and ends. ‘To the SCIENCE. 449 economist ends, rather than means, are im- portant all the time. The economist, as a rule, has laid so much emphasis on means as to diffuse the sum total of impression made upon the mind of the community. Never- theless, the individual member of the com- munity and the community as a whole are interested in results, in ends, in income rather than in outlay, but the income in which they are interested is not the mone- tary income, but real income. I may illustrate this by supposing that in case of our civil war, the policy of the northern states toward the south had allowed ex- ports to be made unhindered, but had pro- hibited all imports except gold and silver. What would the effect have been? The great majority of people would at first hand say that it would have enabled the confederate states to command the control of all utilities they desired, and thus worked exactly contrary to the blockading polhey. But would that have been the ease? We see that it would not, as soon as we realize that gold and silver are means and not ends. If the prohibition of im- ports of economic goods, except gold and silver, had been carried out, the productive process would have been interrupted and the starving-out policy have gone on sub- stantially as it did under the blockade. This illustrates the relative importance of the productive process as distinguished from the monetary movement. Workings of the Anthracite Coal Strike Agreement. Ww. H. Taytor, St. Clair Coal Company, Scranton, Pa. This strike was inaugurated May 12, 1902. Five months later President Roose- velt appointed the commission ‘“‘to inquire into, consider and pass upon the questions in controversy in connection with the strike in the anthracite region, and the causes out of which the controversies arose. By the action you recommend, which the 450 parties in interest have in advance con- sented to abide by, you will endeavor to establish the relations between the em- ployers and the wage workers in the an- thracite field, on a just and permanent basis, and, as far as possible, to do away with any causes for the reoceurrences of such difficulties as those which you have been called upon to settle.’’ Meanwhile the strikers returned to work. Five months later, March 18, 1903, the commis- sion made its report to the president. The report says: ‘‘The occasion of the strike of 1902 was the demand of the United Mine Workers of America for an increase in wages, a decrease in time, and the payment for coal by weight wherever practicable; and where not, then paid by car. The eause lies deeper than the occasion, and is to be found in the desire for the recognition by the operators of the miners’ union. The great strike of 1900 which resulted in an advance of ten per cent. in the wages paid to all classes of mine workers, did not leave either miners or operators in a satisfied state of mind, for both agree that since the settlement of 1900 there have been in- creased sensitiveness and irritation in the mining districts as compared with the previous twenty-five years or more.’’ Every coal mining company finds, as to the discipline, that there is generally a de- cided change for the worse; which, al- though it is known to exist, and is shown in many ways, is still difficult to define. Formerly employees seemed to be willing to turn their hand to anything that would further the work of the company, but now- adays if a man is asked to do a little out- side of his regular line, he refuses to do it or does it grudgingly, telling the foreman ~ that it is not his job. The feeling of sensitiveness and irrita- tion to which the commission referred, has not lessened, but, on the contrary, is a smouldering fire, which breaks forth at the SCIENCE. [N.S. Vou. XXI. No. 534, least provocation. The effect of this un- favorable attitude on operations is reflected in the following typical results showing ~ decreased efficiency generally. One company reporting on all its eol- lieries writes: ‘‘We find that the labor cost of producing coal during the period from November 1, 1903, to April 30, 1904, was 36.9 per cent. greater than during the same months in 1899 and 1900.’’ Two other collieries in the Lackawanna region furnish the following statement, showing decreasing efficiency : TABLE OF COMPARATIVE EARNINGS AND OUTPUT.

The Present Status of Railroading in China. CHuune Hur Wane, Yale Uni- versity Law School. The present method of railroading in China constitutes one of the prime factors in the shaping of the future destiny of that country. While other countries are now lined with networks of railways, we find Marcu 24, 1905.] that in China the ‘iron road’ has not yet become a household word. Foreign ob- servers who have but a superficial view of the subject do not hesitate to attribute the cause of this to the superstition, ignorance, prejudice, and what not, of the Chinese people. In my opinion there are two fundamental causes back of this, the one financial and the other political. If we bear in mind that the construction of every mile of railroad costs upwards of $10,000, we can well imagine the financial diffi- culties with which we are confronted in the construction of a complete system of rail- roads. Moreover, the heavy indemnities and exactions which have been wrung from us by the foreign powers at different periods since the Opium War of 1841 up to the Boxer uprising of 1900 have almost exhausted our resources, and have con- sequently increased the difficulties of our problem. Again, railroading is more than a mere economic undertaking; it has polit- ical as well as strategic importance. The main objection which has been urged by the high officials against the adoption of railroads is that as long as China is not strong enough to defend herself against foreign aggressions, the presence of rail- ways would be a constant menace to the safety of the country. If we read the Chinese state papers on the subject, we shall notice that the problem has been somewhat overestimated in its political and strategic importance, and underestimated in its eco- nomie and commercial aspects. To Li Hung Chang is usually given the eredit for the construction of the first permanent railway in China in connection with the Kiping coal mines, eighty-four miles northeast of Tientsin; but the credit. is justly due to a subordinate official, Mr. Tong King Shing, the pioneer of the intro- duction of modern improvements into China. After the Chino-Japanese War of 1896, SCIENCE. 451 the idea of constructing railroads exclu- sively with Chinese capital was abandoned as being impracticable, and in March of that year an Imperial Edict was issued en- couraging the construction of railroads, and in October, an official of high rank, Sheng Sun Hawai, was appointed Director-Gen- eral of Railroads with full power to raise foreign loans. This was the beginning of the period of ‘concessions.’ Within the past few years ‘railroad con- cessions’ covering about 5,000 miles of rail- way lines have been granted to different syndicates, the largest of which is the Belgian. These ‘concessions’ provide that the ownership in the railways ultimately reverts to the Chinese government. Con- cessions are really contracts between the native company of Chinese railways and the foreign syndicates. Can the South Manufacture Her Own Cotton? CuarutEes Lee Raper, Univer- sity of North Carolina. Slavery was a decided hindrance to the highest industrial development, just as the free negro and the free negro’s ghost in politics are obstacles to present industrial progress. The new south is not largely a product of outside energy and eapital, but is a revival and continuation of the old life; she is a product of the ability of the south- ern white man working under new condi- tions. Though the new south is still far behind the north in wealth and industrial activity, the first twenty years of her life saw more remarkable progress than any other section of this extensive country. General statistics are not all the evidence that goes to the support of the conviction that this section can become the world center of the manufacture of cotton goods. There is much in the general situation to which statistics ean not give adequate ex- pression. Climate, lack cf damaging frost, 452 creat water power and its freedom from ice, and the cheapness of hcusing, clothing and feeding the operatives, are all in favor of this view. The specific facts of cotton manufacture during the last twenty-four years show that in 1880 the southern states had less than 700,000 cotton spindles and about $20,000,000 invested in ectton fae- tories. To-day they have about 8,000,000 spindles, or more than eleven times as many as in 1880. To-day they have almost $200,- 000,000 invested in factories, or ten times as much as they had twenty-four years ago. The greatest need of the present is the direct sale of the products of the cotton mill to consuming markets. This is grad- ually being supplied, and with it the com- plete chain of economie production—the farmer, the manufacturer, the carrier and the merchant—will be primarily in control of the section of the country which is the source of the raw material. SFSSION ON EDUCATION AND SOCIAL SCIENCE. Ameliorative, Preventive and Constructive Social Work: and the Ideal Training for Social Workers. Mrs. ANNA GARLIN Spencer, New York School of Philan- thropy. Social service and social work mean, first, a synthesis of that which is connated in the four basic institutions of society, the home, the school, the church and the state. Social service has in it something of the religious appeal to grow better and stronger, however difficult the growth may be. It has much of charity’s special quality of devotion to those whose personal or social condition makes it most hard for them to live a truly human life. It has some- thing of that dependence upon the organ- ized whole of sceiety which has given the modern state its functions of charity, edu- cation and publie enlightenment through free public benefits. It has much of that spirit of moral reform which i: forever SCIENCE. [N.S. Vou. XXI. No. 534. blazing out in holy passion of rebuke against tyranny of the weak by the strong. It has, most of all, a giant share of that new impulse in education which demands for each child ‘the best development society ean afford.’ The supreme distinction of modern social service lies in its fundamental ideals and the conscious purpose in its application of those ideals. Those fundamentals are: 1. A belief in what Horace Mann ealled the ‘infinite improvability of mankind,’ a deep faith in the essential good quality of human nature, a faith shared with all new types of religious belief and the root of the new education. 2. A belief that the race is not improved solely or chiefly through its moral and inteliectual elite (those capable of becom- ing saints and sages and leaders), but that the race is to be improved most completely and surely by the upraise of the whole mass of mankind. This is a faith in the spiritual essence of democracy. 3. A belief that here and now society has both the duty and the power to under- take consciously, determinedly, systemat- ically and hopefully this upraise of the whole people, this demonstration in terms of absolute democracy of the worth of all human beings. 4. The belief that in order thus to grow nobler, purer and stronger and happier human beings in this wholesale fashion, so- ciety must also work to make a better world for the less fortunate and the weaker hu- man beings now living. 5. The belief that since all the people, especially ‘the least of these,’ are to be lifted, society must hold itself responsible for the welfare, the safety, the chance to erow, the opportunity for education and the ability to become self-supporting, of every human being. This then which we eall social service is a synthetic appreciation and use of the Marcu 24, 1905.] new ideals of education, democracy and re- ligion. This synthetic function divides itself into three main departments of social effort, namely: (1) Ameliorative work, (2) pre- ventive work, (3) constructive work. In all great social activities the three de- partments named work together and, there- fore, the efficient organization of all chari- table and reformatory forces is now indis- pensable to social advance. The modern warfare against disease is a perfect illus- tration of the interaction of ameliorative, preventive and constructive social work. At least one third of all the persons who require relief of a charitable nature do so because of illness or physical disability. Child Labor in Southern Mills. A. J. Mc- Ketway, Assistant Secretary of the Na- tional Child Labor Committee. The southern cotton mill industry is eentered in the Piedmont section of the four cotton states that have mountains, namely, North Carolina, South Carolina, Georgia and Alabama. These are the manufacturing states of the south. This industry grew up in a night, and old historic communities, holding fast to their laissez faire doctrine, found them- selves suddenly confronted with the prob- lems for which they had no social experi- ence and no legislative precedents. All of our industries are infant industries. In 1880 there were 667,000 spindles in the southern — states. In 1900 there were 7,000,000. In 1900 there were 412 cotton manufacturing establishments. In Janu- ary, 1904, there were 900, so that this state- ment of their number is antiquated as soon as it is made. The number has been more than doubled in the last four years. South Carolina stands next to Massa- chusetts in the number of spindles, and North Carolina is ahead of either in the number of cotton mills, the mills being SCIENCE. 453 smaller on the average than those of the other two states mentioned. Considering the shortness of the period of this revival of manufacturing, the south as a whole has acted with commendable promptness in recognizing and seeking to remedy the evils of child labor. The conditions of this industry in the southern states to-day are superior to those in either England or New England and probably superior to those that obtained when the industry was at its best in New England and the operatives: were the hardy children of the New Eng- land soil. Despite the stories that have been published in the magazines at so much per column, it is a source of grati- fication to know that people are buying good clothes and good furniture and pic- tures and books and stoves. The homes of the people are three- and four-roomed cottages, an infinite distance from the one- roomed hut, and every cottage has an acre plat of ground, for the garden, while the pigs and the chickens and the cow have quarters of their own. And there is all of God’s out-of-doors for breathing space. There is no night work at the mill, spinning and weaving departments being evenly balanced so that what is spun one day is woven the next. The hours are long, how- ever, from 6 in the morning to 6:30 at night, with an intermission of forty min- utes for dinner and a half holiday on Saturday. And this brings up the fact that there are too many young children in that foree of a thousand workers and that eleven hours and fifty minutes a day is too long for any child to work in a mill, be the work ever so light. Work of the National Child Labor Com- mittee. SamueL McCune Linpsay, Secretary, New York City. The permanent organization of the com- mittee took place at the house of Robert W. de Forest, New York City, November 28, 454 SCIENCE. 1904, with a membership of forty-six per- sons, constituting, perhaps, as remarkable a group of varied industrial, financial, edu- cational and social interests as was ever brought together in America or in any other country. Its membership now repre- sents fourteen states and the District of Columbia. The object is to secure as nearly as practicable uniform legislation and uniform enforcement of laws on this subject throughout the union. The work before the national committee comprises the education of public opinion, on the one hand, and the bringmg to the attention of both the legislative and exec- utive branches of the state and national governments the results of the careful and scientific study of both existing conditions and remedial measures. The national committee hopes to bring together the re- sults of a larger parental responsibility, the better development of the public school system and the enactment of child labor legislation in the several states and terri- tories, and to coordinate these efforts so that the evils of child labor may be eradi- cated from the industrial system of America. The Press as an Educator. Wm. H. Lyncu, Salem Publie School, Salem, Mo. Jules Verne, the world-famous novelist, wisely predicted that long before the middle of the century novels or romances, in volume form, would be supplanted by newspapers. The newspaper of to-day, great as it is, has yet before it a develop- ment and_ potentiality for usefulness scarcely imagined by its most far-seeing and progressive directors. It must be obvious to all thoughtful per- sons that the newspaper may easily be made the medium of imparting valuable instruction in many departments of knowl- edge on which the very latest text-books are mere blanks. Take, fcr example, the [N.8. Vou. XXI. No. 534. experiments of Marconi in wireless teleg- raphy, so minutely recorded and illustrated in almost every newspaper. Would not the study of the despatches, describing the achievements of the great Italian, by boys and girls sufficiently advanced to under- stand them, be infinitely more profitable than the dull book pages they are com- pelled to read concerning the laying of the first ocean cables so many years ago? To this question there can be only one answer. Take another current subject, with the discussion of which the newspapers have been filled in the most instructive and luminous way—that of Venezuela. What might not a competent teacher, with the aid of the press, have accomplished in the treatment of this question toward instilling in the minds of his pupils correct under- standing and conception of the Monroe Doctrine, let us say, or a knowledge of the Spanish-American republics generally and our relations to them? Then there was a ereat coal strike and the war between Russia and Japan. In the school books are a few meager facts and dates, forgotten almost as soon as they are learned, with respect to that basic factor in the industrial world. With the universal interest centered in the sub- ject and the assistance of the newspaper, the skillful teacher could have done more to expand and inform the minds of all those intrusted to his care than all the text- book writers combined. Children should not, of course, be permitted to read every- thing printed, even in the newspapers. The latest advanees in scientific knowledge, the newest inventions and discoveries, in every branch of human endeavor, are all heralded in the morning or evening des- patches. Years hence the text-books will, as it were, embalm them in their solemn pages. Why should the child be compelled to sit in darkness with the light of knowl- edge blazing all around him? Marcu 24, 1905.] Ethnic Factors in Education. Dr. Epgar L. Hewirt, Washington, D. C. To be published in the American Anthropol- ogist. The American Negro. Epwarp L. Buack- SHEAR, Prairie View, Texas. I, Some Survivals of Primitiwe Racial Instincts in the American Negroes.—The absence or, rather, scarcity of islands and peninsulas and bays and seas along most of the coast line of continental Africa has exerted indirectly a profound influence on African character. As a result, the Afri- can tribes have been isolated from all the great historical world movements, and have remained stationary in their social and tribal relations. Deprived of the stimulus of commercial and maritime influences, they have for centuries lain dormant in respect to the higher or organic life of the human species. Herein les the secret of the southern racial problem. The real crux of this diffi- culty is not the mere color of the skin, as is sometimes asserted. It is the sum total of characteristics, mental and moral, of which the exaggerated physique is the material expression and vehicle—it is this that constitutes a race problem when a group of Afro-Americans comes into any sort of relationship for a continued period with an Anglo-Saxon group. Il. Negroism.—By this term is meant to be conveyed an idea of a sum total of the characteristics—the mere color of the skin, while the most obvious, being really, as it is literally, superficial—which is the result of centuries of a heredity dominated by a fixity and sameness of environment as bar- ren of differentiating and developing fea- tures as the Saharan Desert—a _ heredity wherein the mere struggle for animal ex- istence and reproduction was the moving force, a heredity whose sameness of en- vironment and want of contact, either SCIENCE. 455 friendly or hostile, with different human types, resulted in an exaggeration of qual- ities, physical, mental and moral. Add to the influences of this unvarying African environment and heredity all the influences of American chattel slavery which served to still further exaggerate tendencies al- ready abnormally developed, and the re- sultant is what is here designated negroism. The significance of negroism lies in the de- fective attempt, grotesque to the cultured Anglo-Saxon mind, of the African mind to incorporate into its own thought and being, the real living thought and motives of the Anglo-Saxon race. And herein too lies the gist of the negro question. The remedy for negroism is the develop- ment of Americanism, that is, of intelligent self-respect and a manly regard for others; of self-reliance as manifested in industry and economy and self-support; of a sim- ple, pure, healthy, happy home life as op- posed to polygamous indiscriminateness; a regard for peace and good government and good order rather than a scramble for place and power and spoils; a love of ecun- try, of home and a love of God manifested in a life of simple sincere piety rather than in manifestations of religious emotional- ism unaccompanied or uninspired by the spirit of a genuine Christianity. On the Desirability of Founding an In- stitute for the Study of Blood Poisoning. P. A. Maianon, Philadelphia. In these days of immense activity great problems can be settled only by specializa- tion. The prevention of disease is one of these problems. Medical science deals with the cure of disease; sanitary science with its prevention. Medical and surgical science has been much endowed, but sanitary science has somewhat lagged. Sanitary plumbing and sanitary engineering are about all we hear of in connection with sanitary science. 456 The writer has for the last thirty years been associated with the sanitarians of London, the hygienists of Paris and in a general way with physicians taking partic- ular interest in the prevention of disease, and it has oceurred to him that a good pur- pose would be served if an institute were founded in this country for the special study of blood poisoning, particularly as regards the first step of infection. The physiological, chemical and physical com- position of normal blood is pretty well known, but the immediate phenomena which obtain before the appearance of morbid symptoms do not seem to have been studied to any very considerable degree. The main object of such an institute for the study of the different phases of blood poisoning, their cycle and variety, should be to find out and indicate the means to prevent the infection in each ease. Sociological Features of the National Irri- gation Movement. Guy Euuiorr Mir- CHELL, Secretary of the National Irri- gation Association, Washington. No question before the public to-day presents more interesting sociological phases than does the national irrigation question in America, not only through the great number of homes to be created by artificially watering desert wastes but through the far-reaching effect of the work- ing out of a great government irrigation policy and the general education of the American people on the advantages of this practise both west and east. The social side of irrigation ean be de- scribed in the single clause—irrigation sub- divides and resubdivides lands into small home tracts. Irrigated communities average the small- est farms in the world. The most highly developed portion of the west contains thousands of five and ten-acre farms from which men are making comfortable livings. SCIENCE. [N.S. Vor. XXI. No. 534. The social conditions of some of the most intensely irrigated tracts are perhaps the most nearly perfect of those of any com- munities in the world. Now the effect of the great government irrigation work, which is being pushed rapidly forward, will be to create a west- ern empire of new homes and at the same time, incidentally, thoroughly to educate the people of the entire country on the sub- ject of irrigation. The consequence will be that irrigation practises will finally en- thrall the eastern farmer. The facts as they exist in European countries show that irrigation can be practised with great profit even on land which has sufficient rainfall to grow paying crops. Irrigation is a crop insurer, besides producing double yields, and when it is applied to eastern farm lands the same conditions will result which are found in the arid region—the farms will be divided into smaller and better tilled tracts. Along with the prosecution of the gov- ernment irrigation policy and its great agricultural educational features will come the establishment. of rural colonies through- out the entire country, home-acres for fac- tory employees, making them to an ex- tent independent of their daily wage, and the gradual trend of the city congestion back to the land as the primal source of all wealth. Working along with this policy of intensive farming and high cultivation is a recognized movement to engraft a prac- tical agricultural education, nature study and handicraft work, upon our common school system so that men and women of coming generations will both want and strive to own a home on a piece of land and when they secure it will know how to make it productive and attractive. STATISTICAL SESSION. Beef Prices. Frep C. Croxton, U. S. Bureau of Labor. € Marcu 24, 1905.] An advance in fresh beef affects the ex- penditure of the working-man’s family as much as would the same advance in the price of each of the four items, flour, corn meal, bread and milk. An advance in beef of two cents per pound means (if he buys the same grade and quantity), the ex- penditure of an additional amount equal to the cost of lighting, or to taxes and property insurance combined, or to the expenditure for books and newspapers. The retail price of fresh beef at the present time is about ten per cent. above the average for the ten-year period from 1890 to 1899. The value per pound of the fresh beef exported also shows a de- cided advance. The average value for the last five years was 11.4 per cent. above the value for the preceding five years, and 13.3 per cent. above the value for the five years ending June 30, 1894. A study of prices during the last fifteen years shows that with few exceptions the prices of beef cattle, of fresh beef at whole- sale and of fresh beef at retail advance and decline together, but not to the same ex- tent. The margin between beef at whole- sale and at retail is usually rather close. While some parts of each carcass are re- tailed at two or three times the cost at wholesale, a considerable portion, if sold at all, must be sold for less than was paid at wholesale. In the early part of the pres- ent month, a ‘top’ carcass which cost the retailer seven cents per pound was sold in Washington as follows: 22 per cent. (in- eluding trimmings) at three cents or less per pound; 30 per cent. (including trim- mings) at six cents or less per pound. The demand for fresh beef at home has increased, owing to the increase in popu- lation, the greater proportion of persons living in cities and towns, and to improved industrial conditions during the past few years. The demand abroad, as shown by our exports for the five years ending June SCIENCE. 457 30, 1904, was 21.7 per cent. greater than for the preceding five years, and 55.6 per cent. greater than for the five years end- ing June 30, 1894. The most difficult question encountered in a study of beef prices is that of the supply. The estimates of the Bureau of Statistics of the Department of Agricul- ture show an increase from 1890 to 1904 of 15.6 per cent. in the number of cattle in the United States, while in the same time population increased about 30 per cent., and the exports of fresh beef in- ereased 72.9 per cent. Deducting the amount of fresh beef exported from the amount sold by wholesale slaughtering and packing establishments, the number of pounds remaining per capita was 40.5 in 1890, 34.1 in 1900 and is estimated at 40 pounds in 1904. These figures do not of course represent consumption, but afford some measure of the relative amount of fresh beef sold in each year. One of the most important factors in de- termining the beef supply is the corn crop. The price of corn makes more abrupt changes than does the price of cattle, yet the course of the prices of the two com- modities is almost identical. Above are considered what may be called the natural conditions in the beef industry. It is possible that combinations of packers exist, which would doubtless exert a steadying influence on declining prices; or a combination might be strong enough to control to some extent the prices of cattle bought for slaughtering, or the supply of beef shipped, which would seriously affect the price to the consumer. Movement of Wood Prices and their In- fluence on Forest Management. B. E. Frernow, formerly U. 8S. Division of Forestry. Dr. Fernow refuted, by means of statis- tices presented in the form of diagrams, 458 the position of one of the noted English statisticians, Mulhall, that wood prices had fallen and would continue to fall, because the supply of timber was practically inex- haustible. The data upon which the Eng- lish authority based this conclusion were shown to be worthless. The speaker pointed out the difficulties of securing use- ful data, from which to diagnose the past and predict the future of price movements, and explained that, and why, prices for lumber did not really represent prices for wood or stumpage. From careful compila- tions of the experiences of European forest administrations it was shown that wood prices had for fifty to seventy years in- creased at a compound rate of not less than 1.5 per cent. and for the last ten years at a rate of over 2 per cent., being now at least double what they were fifty years ago. Such data as were available for the United States showed the same tendency and about the same rate; and as the knowledge of the condition of timber supplies in the world was growing, wood prices would in- erease at an accelerated rate ‘until that level has been reached which forces reduc- tion of consumption.’ The influence of the increase of wood prices on forest treat- ment was discussed at length, as tending to supplant the rough exploitation which alone appeared profitable at present, by forestry, 7. e., care for the reproduction of a new wood crop.

The Wheat Situation in the United States. Joun CasseL WriuuiAms, Washington Correspondent, New York Journal of Commerce. SCIENCE. [N.S. Vou. XXI. No. 534. Since the season of 1901 there has been a falling off in the production of wheat in this country, while the increase in consump- tion has gone steadily forward until the point has been reached at which, tempo- rarily, at least, domestic consumption is about equal to the domestic supply and only a small surplus is available for ex- portation. The final figures of the De- partment of Agriculture for the wheat crop of 1904 issued by Chief Statistician Hyde put the total yield at 552,399,516 bushels, against 637,822,000 bushels in 1903, and 748,400,000 bushels in 1901. Though in some years there have been considerable quantities of wheat carried over from one season to another in the visible supplies and in the stocks estimated as remaining in the hands of farmers, the exports of wheat and wheat flour have, from year to year, afforded an approximate measure of the excess of production in the United States over the domestic demand. Owing to the falling off in production and to the increase in domestic consump- tion, exports of wheat from the United States have temporarily, at least, prac- tically ceased and exports of wheat flour have been greatly reduced in volume. The American miller, endeavoring to re- tain his foreign market, is hampered, not only by the shortage of the domestic supply of wheat, but, also, by the inferior quality of a large proportion of that grown dur- ing the past season. The evidence sub- mitted to the treasury department by millers who have asked for an allowance of drawback on the exportation of flour made wholly or in part from imported wheat shows that, while in former years an average of four bushels and twenty pounds of wheat have been required to make a barrel of flour, the average quantity of domestic wheat required this year is four bushels and fifty pounds. Complaint Marcu 24, 1905.} is made that, even if domestic wheat is used to make flour for export, it is ex- tremely difficult to make the quality neces- sary to keep up the reputation of the es- tablished American brands. Across the northern border in Canada there are ample supplies of wheat of good quality, if the Ameriean miller could draw upon that supply of his raw material. The great body of the millers would welcome the absolute repeal of the duty on foreign wheat and there would doubtless be a vigorous demand for this repeal from other elements in the population of the United States if it were generally under- stood that, for some months past, the price of wheat in Canada has been from fifteen to twenty cents per bushel lower than in the United States, and that the effect of this has been to increase the cost of flour in the United States by from eighty-five cents to one dollar per barrel, thus increas- ing the cost of living to every customer of wheat flour in the United States. What is to be the future relation of the domestic supply of wheat in the United States to the domestic demand? The operation of certain tendencies in Amer- ican agriculture seem to indicate that wheat production in the United States can not be expected to increase in the future at a much greater rate than will be neces- sary to supply the increasing domestic de- mand. It is not impossible that the ulti- mate result of the operation of these tend- encies will be to make the United States a permanent importer of wheat under nor- mal conditions. SESSION ON PROBLEMS OF COMMERCE, ETC. Present Status of Maritime Enterprise. Winturop L. Marvin, Secretary of the United States Merchant Marine Com- mission, Boston, Mass. While ocean shipping is in a distressed condition in Europe, it is in a desperate SCIENCE. 459 condition here. The Merchant Marine Commission has visited within eight months all of the chief ports of this coun- try and it has not found anywhere so much as one new steamship designed for foreign trade in process of construction. It is, therefore, more than temporary depression which afflicts the ocean shipping of the United States. We are face to face, unless something heroic is speedily done, with the final vanishing of an old, historic industry. It will be generally agreed that President Roosevelt sent his urgent appeal to Con- gress none too soon. The report and recommendations of the Merchant Marine Commission will be laid before the Senate and House next week.* Though they can not be outlined beforehand, of one fact every member of the Congressional Com- mission is certain, and that is, that with- out vigorous national aid and encourage- ment of some kind we shall inevitably lose the last of our deep sea mereantile marine, not only the ships themselves, but the skilled officers and seamen. The Merchant Marine Commission in its inquiry has found that all the maritime nations of the world protect and encourage their ocean shipping in some way or other. The most conspicuous instance of this practise is Great Britain’s recent grant of $13,000,000 to build two new Cunard steamships, which will receive besides an annual subsidy of $1,100,000 for twenty years. Within sixty years Great Britain has expended about $300,000,000 in sub- sidies to her steam lines through all quarters of the world; and this, with the vigorous discrimination of Lloyds against foreign shipping, has made impregnable the British mastery of the sea, which was first gained by the navigation laws of Cromwell and the victories of Nelson. Report No. 58th To be had upon application * Senate Document, PAT ES 5). Cong., 3d Sess., 70 pp. to Senator Gallinger. A160 SCIENCE. The Merchant Marine Commission has given some attention to the free ship policy. In reply to inquiries addressed to the chief American owners of foreign-built steamships, these companies one and all declare that they would not bring their foreign ships under the American flag if they were given an opportunity, unless Con- gress by subsidy, bounty or discriminating duty enabled them to meet the higher wages of American officers and seamen. The Merchant Marine Commission, therefore, has been forced to turn to the alternative of direct national aid and encouragement to our merchant shipping. The exact con- clusions which it has reached will be re- vealed when the report and recommenda- tions are presented to Congress. Unconsidered Phases of Foreign Trade. Haroutp Boucr, Washington, D. C. To be published elsewhere. This paper was presented orally and ‘dealt with the inadequacy of efforts on the part of the United States to secure a more favorable commercial position in the Far East, in South America and elsewhere, where the best efforts of rivals were making it more difficult each year for the United States to obtain a footing. Analogies Between the Evolution of Inter- national and of Private Law. Epwarp Linpsay, Warren, Pa., Academy of Sci- ences. As the ethics of a people are in advance of its laws so are the ethics of the individ- ual always in advance of the ethics of the people as a whole. The individual is al- ways in advance of the crowd, the group or the state. We would, therefore, ex- pect to find the laws governing nations in their intercourse with each other in a less developed state than those governing in- ‘dividuals in their relations with each other. Such is in fact the case. A comparison of [N.S. Vou. XXL. No. 534, international law with the growth and progress of private law will afford infor- mation as to the stage and development international law has reached and some- thing of what we may expect from its future growth. This comparison was made between : 1. Treaties and Contracts.—Treaties are contracts between nations. In_ inter- national law in respect to treaties the bind- ing force of the engagement is determined more from the formalities of the declara- tion of the treaty than from the agree- ment itself. In an earlier stage of private law this was also true of contracts; origin and history of contracts. 2. War and Trial by Combat; War the Recognized Means of Settling a Dispute.— In private law at a certain stage was em- ployed the judicial combat which degen-- erated into the duel and has now become obsolete. 3. Arbitration and an Action at Law; Arbitration a Rudimentary Judicial Proc- ess.—In private law we have it to-day as a survival in some instances and there is much reason to think that it was a stage in the evolution of law courts and legal pro- ceedings which was passed through by these institutions. International law may be expected to follow the same course of development in general as private law. International legislation, however, prob- ably is inadvisable. Growth of inter- national law best assured by international court to ascertain and declare the law in concrete cases. The Meaning of Maritime Expansion. JOHN FRANKLIN CROWELL, Washington, Dac: The upshot of it all is that we as a people are in the tropics. Moreover, we are there in all probability to stay. Ten or fifteen years ago a professor of history sneered at the idea of the annexation of Cuba. But Marcu 24, 1905.] the recent reciprocity treaty put the com- mercial relations between the two countries on a basis which makes economic annexa- tion inevitable. Furthermore, every lead- ing British possession in the West Indies has for some years been seeking reciprocal trade treaties with the United States, as a means of economic salvation. The fact is that the American tropics find their nat- ural market for raw materials in the United States. We must find enlarged markets in these as yet undeveloped peoples. Step by step both the pressure from within and the course of events from without are drawing us out into relations with transoceanie countries which already make it necessary to look to the main- tenance of communication with the differ- ent continents by sea. At last then we are numbered among the great powers which have borne the burden of the world’s colonization. We are there primarily because of the inequality in the degree of economic development, compar- ing tropical communities with our own. The relation of the more highly developed countries of the temperate zone to the com- paratively undeveloped peoples of the tropies is one of the greatest of problems arising out of maritime expansion. The experience of most countries has resulted in one form or another of political depend- ence on the part of the natives; this polit- ical dependence with its varied institutions has its basis generally in an economic dependence or rather interdependence. Among these economic relations are in- variably lines of communication and com- merece by sea between the foreign country and the dependent territories. Great Britain requires control of the Mediter- ranean by reason of her relations with Egypt, India and Australia. One can not understand the history of modern peoples without taking into account this relation SCIENCE. 461 of the white races to the tropical peoples. With all of its dark pages, there are many proofs of the truth that the greed for gain has been subordinated to dictates of hu- manity, in dealing with these wards of the northern races. The missionary spirit has helped to temper the ferocity of mammon, and sooner or later insisted on the abolition of slavery throughout the entire region of eonquest. There has been a moral ex- pansion running parallel with the political and the economic expansion. Develop- ment of purchasing power rather than wasteful exploration of the population has come at last to govern tropical policy. JOHN FRANKLIN CROWELL, Secretary. THE SAINT PETERSBURG CONFERENCE ON THE EXPLORATION OF THE ATMOSPHERE. As some readers of ScrENCE may remem- ber, the International Meteorological Con- gress which met at Paris in 1896 appointed a committee to further the exploration of the free air, then already in progress in Europe by means of balloons, and at Blue Hill in this country with kites. The committee bears the somewhat ambiguous name: ‘International Committee for Scien- tific Aeronautics,’ and has had for its presi- dent Professor Hergesell, director of the meteorological service of Alsace-Lorraine. Originally consisting of eight members, it now numbers about fifty, representing eleven European countries and the United States, for, although our national Weather Bureau has not had a representative on the committee, the writer attended the meet- ings that were held at Strassburg in 1898, at Paris in 1900 and at Berlin in 1902, and has endeavored to advance the objects of the committee in the United States. The fourth meeting, appointed for last autumn at St. Petersburg, was regarded as of exceptional importance and, according- 462 ly, the invitations issued by the Imperial Academy of Sciences brought together, from ten countries, seventeen members of the committee besides about sixty other meteorologists and aeronauts, the latter both civil and military. At the head of the local committee of arrangements was General Rykatchef, director of the Central Physical Observatory, and to him the sue- cess of the meeting is chiefly due, for, al- though the war with Japan had reached an acute stage, it was not allowed to alter the scientific and social program. The first session was held in the palace of the Acad- emy of Sciences on August 29 (new style), when the order of business was adopted, and the same afternoon the conference was formally opened by the Grand Duke Con- stantine Constantinowitch, president of the Academy, who brought the greetings of the Czar: General Rykatchef then explained the arrangements that had been made for the meeting and Professor Hergesell reported on the work that had been accomplished since the committee had met two years before. The following day the scientifie meetings were begun, these being open to members of the conference, and, with the exception of two days devoted to excursions, they continued until September 3. There were sessions both morning and afternoon which were presided over successively by two members of the committee, and the ques- tions considered came under the following heads: Organization of international ob- servations, special investigations, instru- ments and technical matters, resolutions. As regards the first, it was deemed essential that each country should possess a special organization for the exploration of the at- mosphere and that the results should be published regularly. During the past three years the cost of publishing such observations in monthly volumes has SCIENCE. [N.S.. Vox. XXII. No. 534, amounted to $10,000, and this has been borne entirely by the meteorological sery- ice of Alsace-Lorraine. It is now pro- posed that the various countries participat- ing in the exploration of the atmosphere shall contribute $1,000 or $1,200 annually, receiving in exchange copies of the publi- cation, and this proposition is to be trans- mitted through diplomatic channels to the countries represented at the conference. With respect to the international ascen- sions of kites and balloons which, for sey- eral years, have taken place on the first Thursday of each month, it was decided to continue this practise, but, in order to study the successive diurnal changes, there will be, in addition, ascensions on three con- secutive days during April and August, 1905, the dates during the latter month including the day of the total solar eclipse, August 30, when an ascent of a manned balloon was promised at Burgos, by the Spanish representative, Colonel Vivez y Vich. It was also decided that the balloons should be despatched in each country at the hour which corresponded to its daily synoptic weather-map. A statement of the number of ballons-sondes lost in Europe showed that this did not exceed four per cent. of those liberated. The committee recommended that observations of cloud- drift should be made at the time of each balloon ascension, in order to determine the motion of the upper currents, and in these observations the nomenclature of the clouds ought to correspond exactly with the inter- national classification. For this purpose a new edition of the ‘ International Cloud Atlas,’ which is now out of print, will be issued. Dr. Assmann, director of the aeronautical observatory of the Prussian Meteorological Institute, described the new observatory to be erected in large grounds, thirty-five miles southeast of Berlin, because at the existing Marcn 24, 1905.] observatory, in the suburbs of that city, the trailing kite-wires constitute a danger to life and property. The new establish- ment will be in every respéct a model one, where balloon and kite ascensions are to be made several times a day, a motor-boat on a lake permitting the kites to be flown even in calm weather, and, im this way, it is ex- pected that practically continuous meteoro- logical records will be obtained in the free air. As an indication of what had already been done in this respect, Dr. Assmann ex- hibited a chart, encireling the hall, on which were plotted the isotherms at different heights above Berlin, obtained from the ascensions of kites and captive balloons made daily for more than a year. From them Dr. Berson showed that the wind- direction shifted to the right-hand with in- creasing altitude. To complete an account of the aeronautical establishments in Ger- many for atmospheric soundings, Professor K6ppen described the kite-station of the Deutsche Seewarte, in Hamburg, where kite-flights are made every day that the wind conditions allow, the observations being published the same day, with those obtained simultaneously above Berlin, in the weather-bulletin issued by the See- warte. Professor Palazzo, director of the Italian Meteorological Office, recounted what was being done in Italy to explore the free air, including the recent use of ballons- sondes, and General Rykatchef explained the development of the aeronautical section of the Constantine Observatory at Paw- lowsk, which was later visited by the mem- bers of the conference. Here kite-flights are made whenever possible, the observa- tions being immediately published in the Synoptic weather-report of the Central Physical Observatory. The committee con- sidered that a balloon and kite-station in the southeast of Europe is desirable and ex- pressed the hope that the Roumanian SCIENCE. 463 Meteorological Service would cooperate in the international ascensions, and also that a kite-station might be established at Pola, Austria, thereby filling a gan in the dis- tribution of such stations. Mr. Rotch stated that from the observa- tions obtained with kites at Blue Hill dur- ing eyclones and anti-cyclones the former appeared to be the warmer up to a height of at least two miles. Per contra, M. Teisserene de Bort concluded from his ob-* servations with ballons-sondes in France that the vertical decrease of temperature in cyclones up to six miles was faster than it was in anti-cyclones. This last speaker gave an account of flying kites from a Danish gunboat in the Baltic in 1903, when the record height for kites of more than 19,000 feet was reached, as mentioned in Science, Vol. XVIII., pages 113-14, and he also described recent experiments on his own steam-yacht in the Mediterranean. The most interesting communication, how- ever, was by the president of the committee and related to the atmospheric soundings with kites that he had just executed on board the steam-yacht of the Prince of Monaco, while cruising in the Mediterran- ean and in the vicinity of the Canary Is- lands. It will be remembered that the present writer proposed a more extensive campaign of this nature at the Berlin Aeronautical Congress, and unsuccessfully apphed to the Carnegie Institution for a grant of money to equip a steamship to make a series of kite-soundings through the trade-winds and doldrums. in 1902 he endeavored to interest the Prinee of Monaco in such a scheme, as his colleague, Professor Hergesell, ceeded in doing two years later, and the results of these soundings, which Professor Hergesell announced at St. Petersburg, eminently justified the cooperation. The northeast trade-wind was seen to diminish Moreover, suc- 464 and become more easterly at the height of a quarter of a mile, then falling calm, and even though the kites were lifted by the motion of the vessel to a height of nearly three miles, the southwest anti- trade, which is supposed to form the re- turn-current, was not encountered, though it has been reported at a much lower alti- tude upon the Peak of Teneriffe. The temperature was found to decrease up to ea third of a mile in height, where there was an inversion of temperature persisting throughout a thick stratum and then a rapid decrease with increasing height, these changes being analogous to those pre- vailing within areas of high barometric pressure over the land. The interesting investigations of Professor Hergesell fur- nish additional evidence of the importance and feasibility of carrying out soundings of the atmosphere across the equator and into the southeast trade-winds. The em- ployment of kites to obtain meteorological observations on steamers pursuing vheir regular courses, the practicability of which the writer demonstrated on a voyage across the Atlantic in 1901 (see Science, Vol. XIV., pages 896-7), was discussed and it was reported that two German steamship lines and a Spanish company had agreed provisionaliy to allow observations with kites to be made on their steamers. In view of the importance of studying the meteoro- logical conditions high above the oceans, the committee requested the meteorological bureaus of the various countries to propose to their maritime agencies that kites be employed on the mail and other subsidized vessels, the results of these negotiations to be reported at the next conference. Recording instruments for balloons and kites were discussed in detail, but it was considered inexpedient, at the present time, to recommend the adoption of any special type of instrument, though the committee SCIENCE. [N.S. Vou. XXL. No. 534. requested that a description of the instru- ment employed should accompany all pub- lished observations. The errors of aneroid barometers, caused by residual elasticity and by temperature, were said to be less with the Bourdon tubes than with the usual cylindrical vacuum-boxes and, con- sequently, the former are to be preferred for ballons-sondes. Very light instru- ments of French and German construction were exhibited, in which the barometer was a Bourdon tube and the thermometer either a bimetallic bar, bent in cireular form, or a German-silver tube ineclosed in a polished one. Professor Hergesell showed his instrument for manned balloons, where the necessary ventilation of the thermom- eters is supplied by an exhaust fan, placed in the thermometer-tube just mentioned, and driven by a storage-battery and Dr. Shaw, secretary of the London Meteorolog- ical Office, presented Mr. Dines’s simple meteorograph for kites that costs but twelve dollars. An apparatus was shown by the writer for determining on a moving steamer the velocities of the true and ap- parent wind—which latter only is utilized in kite-flymg—the speed and course of the vessel enabling the triangle of forces to be solved. Most of the other apparatus which was brought before the conference related to the balloons or their accessories. The closing session of the conference was a ceremonious one at which Count de La Vaulx, of Paris, and Dr. Berson, of Berlin, gave accounts of the longest balloon voy- age, from Paris to Kief, and the highest ascension, to 35,000 feet, executed by them respectively. As is usual at these international gath- erings, the social entertainments and visits to scientific establishments were the most interesting features. The first of these was an informal reception at the Grand Hotei before the conference opened, fol- — Marcu 24, 1905.] lowed the next evening by a sumptuous banquet at the Army and Navy Club, which was attended by the Grand Dukes Con- stantine and Peter, as well as by many Russian officers and scientific men of high rank. The Imperial Geographical and Technical Societies held a joint session in honor of their foreign guests, which was followed by a supper. After a morning spent at the Pawlowsk Meteorological Ob- servatory, when a ballon-sonde and kites were sent up from the aeronautical grounds, the Military Aeronautical Park was visited in the afternoon and here all the apparatus of the balloon corps could be inspected, including that which its com- mander, Colonel Kowandko, was about to take to the seat of war in Manchuria. An- other day was oceupied by an excursion into the Gulf of Finland on a small govern- ment cruiser. Notwithstanding a gentle wind, the light hemispherical kites of Mr. Kusnetzof were easily raised by the motion of the vessel and proved very stable.

When the first volume appeared we praised it without stint, expressing the hope at the same time that the other volumes would be up to the standard of the first. This hope has been realized, for the work has shown the rare merit of evenness throughout. Asvolume after volume has appeared, the medical world has become more and more apy preciative of it until now all that we can say is of little account, for each reader has his own opinion of the work ; at least it would seem so from our observation. The opinion oftenest expressed is in accord with our own, namely, that the work is by all odds the best presentation of the science and the art of medicine in the English language.”—New York Medical Journal. ‘« The increasing frequency with which this system of medicine is referred to in general medical literature indicates the popularity of the work and the authoritative nature of the contributions... .

Some of the ablest contributions now being made to educational literature are appearing in the JournaL or Pepacocy. A REPRESENTATIVE OPINION “Tn building up the occupation ot teaching till it becomes a true profession, no magazine is rendering more significant and vital service than the JOURNAL OF PEDAGOGY, which admirably displays the interest of the editor in the science and art of education. Its articles have always been noteworthy for their strength and freshness; its book reviews have been conspicuously valuable, exceeding in number those of the several other leading magazines combined. No field of edu ‘ational effort has been neglected ; and there has been a reason- able apportionment of space alike to the university, the high school, the elementary school, and the kindergarten. Those who are earnest for the better- ment of American education view with the greatest seriousness the endeavor of such a magazine as the JOURNAL OF PEDAGOGY to represent the best thought and practice of the times, and by representing that thought and practice to encourage their influence. To publish such a periodical is a noble enterprise for the welfare of American schools and of the American nation.’’—Dr. W. E. Chancellor, Superintendent of Schools, Paterson, N. J.

THE SIXTH ANNUAL MEETING OF THE S8O- CIETY OF AMERICAN BACTERIOLOGISTS. THE sixth annual meeting of the Society of American Bacteriologists was held at the Laboratory of Hygiene, University of Pennsylvania, Philadelphia, Pa., on De- cember 27 and 28, 1904. The opening address was by President F. G. Novy, of the University of Michigan, on ‘The Hematozoa of Birds.’ On the Hematozoa of Birds: F. G. Novy, University of Michigan. An abstract or partial summary of the results obtained in this study appeared in American Medicine, November 26, 1904. The work in full will come out in two papers, the first of which, dealing with the Trypanosomes in birds, will appear in the second number (1905) of the Journal of Infectious Diseases; the second paper, deal- ing with the Cytozoa, may be expected in the third number of that journal. The Effect of Freezing on Bacteria: ERWIN F. SmirH and DEANE B. SwIncte, U. 8S. Department of Agriculture. More than 100 freezings were made using about a dozen different bacteria— saprophytes and plant and animal patho- genic forms. Quantitative determinations were made in all cases. With the excep- tion of Bacillus radicicola, all of the ex- posures were made in +15 peptonized beef bouillon, using cultures 24 to 48 hours old. Part of the freezings were made in liquid air, the time of exposure varying from 10 minutes to 24 hours, but usually one half hour. The rest were made in salt 482 and pounded ice, the time of exposure be- ing 2 hours. The freezings were made in 5 ee. portions of bouillon in test-tubes of resistant glass. The thawings were made in tap water at 16° to 18° C. The inocu- lations for each set of plates were made in the same way, 2. e., usually with the thin- nest meniscus it was possible to obtain across a l-mm. platinum oese. The petri dishes were carefully selected, those taken being approximately 9 em. in diameter, with flat bottoms. The regular method of work was to make three poured plates (checks) from the inoculated tubes after insuring thorough diffusion, which was obtained by stirring with the platinum rod, shaking and allowing to stand one half hour. The tube was then immediately lowered into the liquid air and frozen slowly from the bottom up to avoid eracking. (This us- ually required four minutes.) As soon as the one half hour or other predetermined time of exposure had elapsed, the tube was removed, warmed for about 3 minutes in the laboratory air and then thawed in water (which usually required another 5 minutes). As soon as the thawing was completed, three more poured plates were made, and these together with the three check plates were then incubated in the dark at 30° C., until the colonies were in good condition for counting—a _ period varying, according to the species, from one to several days. The plates were all put on a leveling apparatus as soon as poured, and in general the distribution of the colonies in the nutrient agar was very uni- form. When the plates were sown thin enough, the entire surface was counted (60 sq. em.); for the thicker sowings the aver- age of 10 or 12 sq. em. was used, or of one half the plate. The following samples from two of the thirty or more slides ex- hibited will give a general idea of the method and results: SCIENCE. [N.S. Vou. XXI. No. 535. BACILLUS TYPHOSUS. (SIX POURED PLATES.)

Streeter’s The Fat of the Land ‘. 0seseiente ae 50,000 St. John’s Collesew ia. soeeirras ae 16,700 During the past week a gift of $100,000 to Rochester University for the construction of a scientific building and $50,000 to Norwich University, Vermont, half for a library and half for an engineering department, have been announced. Ir is announced that a gift of $250,000 has been made to Northwestern University by Milton H. Wilson, a resident of Evanston, and one of the trustees of the institution. Tue London Times states that further papers have been published by the government of India in respect to the late Mr. Jamsetjee N. Tata’s offer of an endowment in the shape of properties valued at £200,000 for the crea- tion of an Institute of Indian Research at Bangalore. Certain conditions in respect to government assistance were attached to the offer, which was first made six years ago, and these have been the subject of prolonged dis- cussion and correspondence between the goy- ernment, Mr. Tata during his lifetime, and his representatives. The papers now published show that the difficulties in the way of a set- tlement have been removed. Guarantees have been offered by the representatives of the donor to secure the full income estimated from the endowment properties, and the management of the latter is vested in a board whose chairman is to be an officer selected by the Bombay gov- struction of the necessary buildings and pro- vision of scientific apparatus, the government wiil make an annual grant to the institute of half the local assets up to a limit of 14 lakhs of rupees, provided that the institute is con- ducted on lines approved generally by the goy- ernment. “ Tue Barney Memorial Science Hall of Denison University was completely destroyed by fire at two o’clock a.m., March 30. The building was erected in 1894 at a cost of $45,000, and the value of the equipment within it was also about $45,000. The department of chemistry, in which the fire started, suffered total loss. The department of physics, which had installed several thousand dollars worth of new apparatus this season, lost most of its equipment, including the greater part of the manuscripts and instruments of the researches of Professor C. W. Chamberlain. The equip- ment of the department of geology, including about $7,000 worth added this year, was nearly all saved. The departments of zoology and botany saved about half of their equipment. There is about $40,000 insurance on the build- ing and contents, and the hall will be rebuilt at once. The most serious loss is the scien- tifie library which has been accumulated dur- ing the past twenty years, chiefly through ex- change with Denison publications and which was one of the richest collections of society transactions and similar serials in the middle west. In making good, so far as possible, this severe loss the generous cooperation of au- thors and learned societies is requested. Au- thors’ separates, duplicates, or society publica- tions, if sent to the permanent secretary of the Denison Scientific Association, Granville, Ohio, will be gratefully accepted as a nucleus of a new library. : Rev. Freperick W. Hamitton, D.D., pastor of the First Universalist Church of Roxbury, has been elected temporary president of Tufts College, to fill the vacancy caused by the death of President Capen. Mr. R. P. Grecory, M.A., of St. John’s Col- lege, has been appointed senior demonstrator in botany at Cambridge. opens | ] | COOP ome antl lt ee, § SCIENCE.—ADVERTISEMENTS.

Y. PENETRATING RADIATION WITH THE ASSOCIATED A-RAYS. As the following investigation is made with the aid of nuclei, certain of their properties bearing on the present subject will first have to be specified. Exhaustions are preferably made at a pressure differ- ence (8p) just below the point (to be called fog limit) at which dust-free non-energized saturated air condenses without foreign nuclei. 6p depends on the particular ap- paratus used. 1. Fleeting Nuclei.—Let the X-radiation to which the dust-free air is exposed be relatively weak, so that the density of ion- ization may remain below a certain critical value. The nuclei observed on condensa- tion are then very small and they require a high order of exhaustion, approaching the fog-limit of non-energized air. They are usually instantaneously generated (within a second) by the radiation, so that their number is definite independent of the time of exposure. They decay in a few seconds after the radiation ceases; 7. e., roughly to one half their number in two seconds, to one fifth in twenty seconds in the usual exponential way. I fancy that these nuclei are what most physicists would call ions; but nevertheless the particles are not of a 562 size, their. dimensions depending on the in- tensity of the penetrating radiation to which they are usually due; and they pass continuously into the persistent nuclei as shown in the next paragraph, where decay of ionization and of nucleation are very -different things. Finally (§3) they are stable on solution. The case seems rather to be one in which the rate of decay exceeds the rate of production. The following is an example of data bearing on this case, N being the number of nuclei caught per. cubie centimeter.

Persistent Nucler.—If the X-ray bulb is approached nearer the fog-chamber or if a more efficient bulb is used so that the density of the ionization within the fog- chamber is sufficiently increased, the rate of production of nuclei will eventually ex- ceed the rate of decay. The nuclei are now persistent for hours after the radiation ceases. The number N per cubic centi- meter increases in marked degree and at an accelerated rate with the time of ex- posure to the radiation, certainly for ten minutes or more, barring the invariable loss of efficiency of the X-ray bulb. These nuclei are large, requiring very little super- saturation for condensation and are much like any ordinary nuclei. They are pro- nouncedly of all sizes and the initial co- ronas are apt to be distorted and stratified beyond recognition. Whirling rains and accompany the first condensation.

The data indicate, moreover, that both of these extreme types of nuclei and all inter- be tested by changing the pressure differ- — ence, 6p, on exhaustion. Intermediate : rates of generation and decay may be ob- | tained by moving the bulb nearer to or farther from the end of the fog chamber. Finally the rates at which the nuclei and the ionization severally decay, between ; which it would be difficult to distinguish in the case of the very fleeting nuclei, stand in sharp contrast with the persistence of — the nuclei of the present paragraph. 3. Fleeting Nuclei Become Persistent on — Solution. Origin of Rain.—ULet the fog- © chamber be exposed to radiation for a few seconds and thereafter exhausted (8p—25) as usual. Closing the exhaustion cock and allowing only time enough to measure the first corona, let the influx cock be opened and the fog-chamber be refilled with dust- free air. The (primary) corona observed is thus dispelled before much subsidence of — fog-particles can take place, though the . rain will naturally drop out. If the fog- chamber is now left without interference * American Journ. Sci, XTX., 175. + Computed from the second exhaustion, after — subsidence of the dense fogs of the first. | ' j ) \ ) Aprit 14, 1905.] (the radiation having been cut off imme- diately after the first exhaustion) for one or more minutes or longer, a second ex- haustion to the stated limits will show a large (secondary) corona relatively to the primary corona. In other words, relatively many of the fleeting nuclei or ions caught in the first fog have persisted, whereas without condensation, they would have van- ished at once after the radiation was cut off. The following is an example of data bearing on this point, ¢ denoting the time elapsed from the evaporation of the first corona to the precipitation of the second, N, the number of nuclei in the first and N, the number in the second corona. =e 60 120 300 seconds. a < LO- 53 27 53 NX 10-3 = 16 7 15 The experiments are complicated by the variable X-ray bulb; but it is obvious that while all the nuclei would have vanished in a few seconds without condensation, about one fourth (in other experiments more) persist indefinitely if reevaporated after condensation from fog-particles. This result has an important bearing on the whole phenomenon of condensation and nuclei. Clearly the latter, after the evap- oration specified, become solutional or water. nuclei, in which the original fleeting nu- cleus or ion behaves as a solute. The de- ereased vapor pressure due to solution eventually compensates the increased vapor pressure due to curvature, after. which at a definite radius, evaporation ceases and a water nucleus results. Such a nucleus, however small, must be large in comparison with the dissolved ion. Hence on conden- sation the water nuclei will capture the moisture soonest and grow largest. Now in any exhaustion about one eighth of the fog particles, 7. ¢., those which are smallest and whose nuclei have been caught at the end of the exhaustion, regularly evaporate into the larger particles to a residue of SCIENCE. 563 water, nuclei. These are then the first to be caught in a sueceeding exhaustion. This is the explanation of the rain which not only accompanies all coronas in dust-free air, but is often dense. It is also an ex- planation of those indefinite alternations of large and small coronas (periodicity) which I described in detail elsewhere. 4. Secondary Generation.—This is a curious phenomenon, showing that the de- caying nucleus is apparently radioactive, or that the walls of the fog-chamber are so, or. else that the large nuclei if left without interference break into a number (on the average about three) of smaller nuclei, whereby the nucleation is actually in- creased in the lapse of time after exposure. In other words, if the nucleation is ob- served without cutting off the radiation in one case, and if in the second ease the nucleation identically produced is observed at a stated time after the radiation has ceased, the number in the latter case (anomalously enough) is in excess. The following examples make this clear, the X- ray bulb being 5 em. from the fog-chamber, and the exhaustion carried to 8p = 20 em.

The determination of the rela- tions of the various sexual phases of the species of the latter family being a matter of considerable difficulty, the collection of suitable material for this purpose consumed much time. The life history of Platynereis megalops proved to be quite as complex as that of the classical P. Dumerilii, present- ing, however, some important differences. With the exception of Nereis arenaceoden- tata, heteronereids of all the species have been found. An additional new species of Nereis was also discovered. The Polynoide and other scaly polycheta are of well- known species, though several new to the region have been found. The large felted polychxte, commonly called the ‘sea mouse,’ of American waters, has always been iden- tified with the European Aphrodite acu- leata. A careful study of specimens taken off Nantucket and Marthas Vineyard show that the species occurring there is quite distinct. The dredging operations con- nected with the biological survey resulted in large collections of polychexta, the de- termination and recording of which re- quired much time. Besides adding several forms to the known fauna of the region, the most interesting of which is the remark- able Spiochetopterus oculatus, this work has added greatly to our, knowledge of the loeal distribution of certain species. Max Morse, fellow in zoology, Columbia University, assisted in the work of the biological survey, as well as in biometric studies carried on by Dr. Sumner. Raymond C.

Apri 14, 1905.] George H. Parker, Ph.D., assistant pro- fessor of zoology, Harvard University, con- tinued, as salaried investigator, his experi- ments of a previous summer upon the hear- ing of fishes, devoting especial attention to the functions of the ear of the squeteague (Cynoscion regalis). The latter consists of a dorsal utriculus, with three semi-circular canals, and of ventral sacculus containing a large otolith. The cavity of the utriculus does not communicate with that of the sac- eulus; hence the ear of this fish, unlike that of most vertebrates, is represented anatom- ically by two separate parts. When the utriculi and their appended semi-circular canals and nerves were cut, the fishes showed characteristic disturbances in their equilibrium, and these disturbances per- sisted till death. Such fishes were as re- sponsive as normal ones to sound vibrations produced by tapping with a mallet on the side of the wooden aquarium in which they were kept. When the otoliths, which are normally quite freely movable in the sac- euli, were pressed by means of pins against the outer, non-nervous sides of their cham- bers and were thus fastened, the fishes showed no disturbance of equilibrium, but did not react to sound vibrations as do normal fishes. It, therefore seems prob- able to Dr. Parker that the utriculus and the semicircular canals are sense organs concerned with equilibrium, and that the sacculus with its contained otolith is an organ of hearing. Henry F. Perkins, instructor in zoology, University of Vermont, and Carnegie re- search assistant, continued his endeavors to rear the eggs of Gonionemus murbachii, with view to a study of the embryology of this form. This task has proved extremely difficult in the past, but preliminary steps were successfully taken. Towing collec- tions of various hydromeduse were also made from the wharf, furnishing material SCIENCE. 571 for a study of the formation of new ten- tacles. L. Charles Raiford, instructor in chem- istry and dyeing, Mississippi Agricultural . College, carried on studies upon the in- testinal bacteria of certain fishes. Cultures were taken from 57 dog-fish and 26 men- haden, and those organisms which appeared to be of constant occurrence were isolated in pure culture. So far as his work has been carried, Mr. Raiford believes that all of the bacteria found are commonly known species. H. W. Rand, Ph.D., instructor in zool- ogy, Harvard University, collected and prepared material for studies of the venous system of the skate. Injections were made of the hepatic portal, cardinal and lateral veins, with a view to determining the rela- tions and connections of these several sys- tems of veins in the posterior region of the abdominal cavity. Dr. Rand also made a series of observations on the respiratory movements of the skate, with special refer- ence to the functions of the spiracle. George G. Scott, M.A., tutor in philos- ophy, College of the City of New York, and assistant in charge of the supply room at the laboratory, carried on studies upon the sporozoa parasitic in various marine in- vertebrates. s Grant Smith, Ph.D., teacher of biology, Chicago Normal School, collected and pre- pared material for the study of the eyes of varlous marine invertebrates. W. L. Sperry, Rhodes scholar elect, car- ried on studies upon the muscular and nervous systems of the star-fish, Astervas forbesi. In this work Mr. Sperry assisted Professor H. L. Clark, who, however, was not himself present this season. Certain features of the musculature were studied in detail and drawn, observations upon the movements of the living animal were made, 572 and experiments were made to determine suitable methods of staining. M. X. Sullivan, Ph.D., instructor in chemical physiology, Brown University, in- vestigated the physiology of digestion in the common dog-fish. Francis Bertody Sumner, Ph.D., instruc- ~ tor in zoology, College of the City of New York, and director of the laboratory, was occupied with (1) work upon the biolog- ical survey of the marine fauna and flora of the vicinity of Woods Hole (see above), (2) the card catalogue record of local spe- cies (see above), (3) experimental and statistical studies of various fishes with reference to adaption and selection. In the experimental part of this work, Dr. Sumner was assisted by Mr. D. W. Davis, in the biometric part by Messrs. Davis, Metcalf, Morse and some other assistants. E. E. Watson, student in Iowa Univer- sity, was engaged in biometric studies of various local erabs. Chas. B. Wilson, A.M., professor of biol- ogy, State Normal School, Westfield, Mass., carried on studies of parasitic copepods, both living and preserved material being used. Many interesting facts relating to the ecology of these parasites, some of pos- sible economic value, were discovered. In a number of cases the life history was traced partially or completely. A consid- erable number of new species were found. Professor Wilson likewise prepared an ex- tensive set of records of local parasitic copepods for incorporation into the faunal catalogue.

ALBATROSS EXPEDITION TO THE BASTERN PACIFIC.* ii: WE left Callao for Easter Island Satur- day afternoon, December 3; as far as 90° west longitude we remained in the Hum- boldt current, as we could readily see from the character of the temperature serials and from the amount of pelagic life we obtained from both the surface and the intermediate hauls. This current also af- fected the bottom fauna, which was fairly rich even as far as 800 miles from the shore while we remained within the limits of the northern current. As soon as we ran out- side of this the character of the surface fauna changed; it became less and less abundant as we made our way to Easter Island, the western half of the line from Callao becoming gradually barren. This current also affected the deep-sea fauna to such an extent that towards Easter Island, at a distance of 1,200 to 1,400 miles from the South American continent, our trawl hauls were absolutely barren; the bottom for the greater part of the line was covered with manganese nodules on which were found attached a few insignificant siliceous sponges, an occasional ophiuran, and a few brachiopods or diminutive worm tubes, the same bottom continuing to Sala y Gomez and between there and Easter Island. Sala y Gomez and Easter Island are connected by a ridge, on which we found 1,142 fath- oms near Sala y Gomez, and 1,696 fathoms between that point and Easter Island. The ridge rises rapidly from about 2,000 fath- oms, the general oceanic depth within about * Extract from a letter of Mr. Alexander Agassiz to Hon. George M. Bowers, U. S. Fish Commis- sioner, dated Chatham Island, Galapagos, January 6, 1905. Aprit 14, 1905.] 100 miles, to over 1,100 fathoms within a comparatively short distance from both Sala y Gomez and Easter Island. The southern part of our line from Easter Island to the Galapagos shows all the features characteristic of the western part of the line from Callao to Easter Island ; like the latter, as far as the twelfth degree of southern latitude, it proved com- paratively barren, the bottom consisting of manganese nodules to within about 250 miles of the Galapagos. The pelagic and intermediate fauna from Easter Island to 12° south latitude was very poor, and the serial temperatures show that we were out- side and to the westward of the great Hum- boldt current. But near the twelfth degree of southern latitude a sudden change took place; the pelagic and intermediate fauna became quite abundant again, and soon fully as rich as at any time in the Hum- boldt current. There was also a marked change in the temperature of the water as indicated by the serials, showing that from the twelfth degree of southern latitude to the Galapagos we were cutting across the western part of the Humboldt current. The great changes of temperature which took place in the layers of the.water be- tween 50 and 300 fathoms are most strik- ing, and show what a disturbing element the great mass of cold water flowing north must be in the equatorial regions of the Panamie district to the south and to the north of the Galapagos. South of the Galapagos the western flow of the Hum- boldt current must be nearly 900 miles wide, and of about the same width when running parallel to the South American coast. : The range of temperatures between 30 fathoms and 150 fathoms is at some points as great as 21°. Such extremes can not fail to affect the distribution of the pelagic fauna, and may account for the mass of dead material often collected in the inter- SCIENCE. 573 mediate tows at depths of less than 300 fathoms, when the range becomes as great as 28°. Such a range of temperature is far greater than that of the isocrymic lines which separate coast faunal divisions. The bottom fauna, as we entered the Humboldt eurrent going north, gradually became richer in spite of its being covered with manganese nodules. ; The two lines centering at Easter Island developed the Albatross Plateau indicated on the Challenger bathymetrical charts, on the strength of a few soundings reaching from Callao in a northwesterly direction and of a couple of soundings on the twen- tieth degree of latitude. The Albatross Plateau is marked as a broad ridge sep- arating the Buchan Basin from the deep basin to the westward, of which Grey Deep and Moser Basin are the most noted areas. Our line from Easter Island to the Gala- pagos showed a wonderfully level ridge, varying in depth only from 2,020 to 2,265 fathoms in a distance of nearly 2,000 miles. The soundings we made to the eastward from the Galapagos to the South American coast, and to the westward of Callao, as well as on the line from Callao to Easter Island, all indicate a gradual deepening to the eastward to form what the Challenger has called the Buchan Basin, with greatest depths of 2,400 to over 2,700 fathoms, and passing at several points near the coast to Milne-Edwards Deep, Haeckel Deep, Kriimmel Deep and Richards Deep, some of them with a depth of over 4,000 fathoms. According to the Challenger soundings the Juan Fernandez Plateau connects with the Albatross Plateau and forms the southern limit separating Buchan Basin from the Barker Basin to the south of the Juan Fernandez Plateau. At Easter Island we found our collier awaiting our arrival. We moved from Cook Bay to La Pérouse Bay to coal, as there was less swell there than in Cook Bay, 574 where we could scarcely have gone along- side for this purpose. Considerable shore collecting was done at Easter Island. We must have brought together at least thirty species of plants. The flora of Easter Island is very poor. There are no trees nor, native bushes—not even the bushes which characterize the shore tracts of the most isolated coral reefs of the Pacific are found there; and yet some of the equatorial counter-currents must occasionally bring some flotsam to its shores. We collected a number of shore fishes and made a small collection of the littoral fauna. The fishes have a decided Pacific look, and the few species of sea- urchins we came across are species having a wide distribution in the Pacific. While coaling, we spent some time ex- amining the prehistoric monuments which line the shores of Easter Island. During our stay at La Pérouse Bay we visited the platforms studding the coast of the bay, and made an excursion to the crater of Rana Roraka, where are situated the great quarries from which were cut the colossal images now scattered all over the island, many of which have fallen near the plat- forms upon which they were erected. Near Rana Roraka, at Tongariki, is the largest platform on the island, about 450 feet in length, to the rear of which are fifteen huge images which have fallen from the pedes- tals upon which they once stood. The plain in the rear of the platform is crowded with stone houses, most of which are in ruins. On our return to our anchorage at Cook Bay, we examined the platforms within easy reach of the settlement, and also the crater of Rana Kao, on the north rim of which, at Orongo, are a number of the stone houses built by the people who quar- ried the great stone images. At Orongo are also found sculptured rocks, but neither the sculptures nor the images show any SCIENCE. [N.S. Vou. XXI. No. 537. artistic qualities, though the fitting of some of the cyclopean stones used in building the faces of the platforms indicate excel- lent and careful workmanship. To Mr. C. Cooper, manager of the Easter Island Com- pany, we are indebted for assistance while visiting the points of interest of the island. He was indefatigable in his exertions in our behalf. We took a number of photographs dur- ing our stay; illustrating not only the pre- historic remains, but giving also an idea of the desolate aspect of Easter Island during the dry season. We arrived at Wreck Bay, Chatham Island, Galapagos, on the third of January, where we found a schooner with a supply of coal. As soon as the ship has been over- hauled and coaled we shall start for Manga Reva, where we ought to arrive the last days of January. We reached Chatham Island towards the end of the dry season. Everything is dried up, the vegetation seems dead with the exception of a few small wild cotton plants, weeds, cactus and an occasional mimosa; and the great barren slopes present fully as uninviting an aspect as when Darwin described them. When the Albatross visited the Galapagos in March, 1891, everything was green, pre- senting a very marked contrast to its pres- ent desolate appearance. ALEXANDER AGASSIZ. SCIENTIFIC BOOKS. Problems in Astrophysics. By Acnes M. Cierkre. London, Adam and Charles Black; Agents in America, The Macmillan Co. 1908. Pp. xvi-++ 567, with 81 illustrations. $6.00 net. Qualified by her authorship of those excel- lent works ‘The History of Astronomy in the Nineteenth Century’ and ‘ The System of the Stars,’ and by her obviously minute and crit- ical study of current research in this field, Miss Clerke presents in her latest work a lucid account of pending problems in astrophysics. Aprit 14, 1905.] Her brilliant style of writing is maintained throughout, and is sure to fascinate even the reader who does not fully comprehend her meaning. Sometimes, indeed, her lavish use of synonyms must puzzle those not familiar with the subject; but it carries her and her readers lightly and pleasantly over some chap- ters that would certainly be dry in the hands of most authors. The keynote of the book is suggestiveness, as the author points out in the preface, and there could be no better tribute to her success in this respect than the use made of her work by astronomers. She clearly differentiates the known and the unknown, and emphasizes what ought to be found out. The book can be commended to the atten- tion of the physicist and the chemist. It is unfortunate that so few workers in the field of chemistry seem to take a positive and active interest in the problems of astrophysics; for in many respects its progress is being delayed while developments are awaited from the chemical laboratories. When these develop- ments come, as when Ramsay solved the mys- tery of helium, the forward movement is rapid. Students of electricity also ought to find considerable of interest in this book and its topics, for our nearest approaches to labo- ratory representations of stellar phenomena seem to be of an electrical character. Yet we really do not know at all how these elec- trical phenomena can be brought into their proper relation to the thermal conditions which doubtless obtain in the stars. The work before us is divided into two parts, ‘ Problems in Solar Physics’ and ‘ Prob- lems in Sidereal Physics,’ the second part oc- cupying something more than two thirds of the volume. The fourteen chapters of the first part deal with the sun’s chemistry, and separately with its successive envelopes. Two chapters are devoted to sun-spots, and they sufficiently disclose our ignorance as to the nature and cause of these familiar but no less puzzling phenomena. The last three chap- ters treat of the solar rotation, the solar cycle and ‘the sun as a whole.” The author’s point of view is the safe and conservative one which has been taught by Young and by Huggins. SCIENCE. 518 Schmidt’s refraction theory of solar phenom- ena is regarded as largely of academic interest. The general reader may safely accept the au- thor’s comments as well balanced; and there is no concealment, but rather a frank avowal, of the extent of our present ignorance on the problems of the sun. Part II. includes forty-one chapters and enters into the personal details—the vie intime—of the stars, possibly rather too minutely for the general reader. But it is decidedly interesting reading, and the reviewer must confess that the belatedness of this re- view is due to the tendency to peruse these details repeatedly to the detriment of obtain- ing a broad survey of the book. The author adopts a rather simple scheme for classifying stellar spectra and gives to each class a chap- ter. Anomalous and bright-line spectra re- ceive an Spectroscopic binaries and eclipsing stars also get consider- able attention. ‘The problem of Beta Lyre’ occupies a chapter of twenty pages, while the longest chapter is devoted to temporary stars, including Nova Persei. After clusters have been discussed, the nebule are taken up in nine interesting chapters, and few of the ob- jects of this class which have been carefully studied are omitted in the author’s detailed treatment. A brief final chapter discusses the physics of the Milky Way. References to the original sources are faith- fully given throughout the work, and appa- rently with few typographical errors, from which the book is otherwise quite free. We wish that Miss Clerke would adopt the use of the convenient word spectrogram instead of making spectrograph serve for both the instru- ment and the photographic result of its use. Slips of the pen seem to be rare, and there are few points at which a conservative reader would interpret the results of observations very differently from the author. The thirty-one insert plates are for the most part excellent. Those printed in the text, except diagrams, are less satisfactory, notably the picture of prominence on p. 104. The light weight of the paper makes the handling of the book a pleasure—and it is likely to ample treatment. 576 be handled rather frequently by many of its owners. Epwin B. Frost. YERKES OBSERVATORY. La Montagne Pelée et ses Eruptions. Par A. Lacrorx. Ouvrage Publié par |’Académie des Sciences sous les Auspices des Minis- téres de l’Instruction publique et des Colo- nies, Paris. 1904. Pp. xxiit 662. 30 plates and numerous text figures. The most complete report on Martinique yet published is that of Professor Lacroix, which embodies the results of his researches during two extended sojourns in the West Indies. Few geologists were better qualified to under- take the task and unusual facilities were of- fered him to make as exhaustive an examina- tion as the conditions would permit of the voleano Pelée. Professor Lacroix was sent, at the sugges- tion of the Académie des Sciences, by the Minister of the Colonies at the head of a scientific commission to study the effects of the eruption of Pelée and to examine into its causes. The commission consisted, in addi- tion to Professor Lacroix, of M. Rollet de VIsle and M. Giraud. After a preliminary visit of little more than a month in June and July, 1902, the party returned to France to arrange for a longer visit in the dry season. The eruption of the thirty-first of August hastened Professor Lacroix’s departure and he arrived a second time at Fort de France on the first of October alone, the other members of the mission being unable to accompany him. During this second visit, which lasted nearly six months, the greater part of the material was gathered upon which the present report is based. Two observatories were established from which the volcano could be watched day and night, and at these posts were cameras and various instruments for the purpose of record- ing with as minute detail as possible all events, or changes in the form of the moun- tain. The results of these observations were correlated by Professor Lacroix, who devoted a greater part of his own time to an examina- tion of the voleano, the collection of speci- SCIENCE. [N.S. Vou. XXI. No. 537. mens, and to obtaining, if one may judge from the illustrations of the book, a large number of very remarkable photographs. In presenting his results Lacroix has ar- ranged them under three heads: The first part, which is by far the longest, deals with the geological and physical problems involved in the eruptions, and contains detailed descrip- tions of the more violent outbreaks. The second part is devoted to a petrographical study of the actual products of the eruption and to a comparison of these with rocks from the other islands of the Lesser Antilles. In the third part, the various products resulting from the conflagration of Saint Pierre are dis- cussed, particular attention being paid to the secondary minerals developed and the effect of intense heat on the old andesite of which most of the houses were built. Much of the information contained in the first part will be familiar to those who have followed Lacroix’s earlier reports and the de- scriptions of the American observers, but cer- tain chapters are of unusual interest to geolo- gists, especially those which deal with the processes involved in the formation of the famous ‘dome’ and ‘spine,’ the theory of the ‘burning clouds’ (nuées ardentes) of the more violent eruptions, the deposits of frag- mental materials, and the various secondary phenomena. After summarizing in chapter I. of the first part the geology of Martinique and the other Antillean islands, and describing earlier eruptions, the author calls attention in chapter II. to the single center of eruption and the absence of secondary vents. A study of the modifications in topography resulting directly from the great eruptions shows them to have been relatively slight, from a geolog- ical point of view, when compared with the devastation wrought. Judging from the reec- ords of cable repair ships no marked changes in submarine topography occurred and the breaking of the cables is attributed to the shelving of deltas at the mouths of streams descending from the flanks of Pelée. In chapter III. Lacroix describes the evolu- tion of the ‘dome’ and offers an explanation of the processes involved in its development. Briefly, the ‘dome’ is the eminence which has ApRIL 14, 1905.] appeared within the old crater (Etang Sec) since the eruption of May 8, 1902, and which was considered by some of the American ob- servers as merely a secondary cinder cone, or an accumulation of fragmental ejected ma- terial about the actual vent. Lacroix denies that it is of fragmental nature and states that it is, in fact, a homogeneous mass of viscous lava surrounded by an envelope of the same substance cooled and consolidated. The ex- planation of this phenomenon and of the re- markable spine of solid rock which has from time to time risen above the dome itself is essentially as follows: The viscous magma on reaching the surface through the throat of the voleano and forming a protuberant mass is quickly surrounded by a solid shell or envelope which protects the still pasty interior from a too rapid cooling. This envelope becomes fissured, under the influence of progressive solidification, and the increase in volume of the mass itself, and through the clefts thus formed fresh molten material is exuded. In this way a homogeneous rocky mass increases in height and volume, bristling with jagged points, glowing like a ‘ charcoal- burner’s fire’ at night, and bounded by abrupt walls which rise from the debris accumulating at its base from incessant superficial crum- bling. Projected materials resulting from violent eruptions play but a small part in the constitution of such a dome. » THE MACMILLAN COMPANY LONDON: MACMILLAN & Co., LTD.

By ERNEST HAECKEL. Translated from the Fifth (Enlarged) Edition by JossepH McCasr. Two volumes, 8vo. With 30 Colored Plates and 512 Other Illustrations, net, $10.00. | HIS work is a comprehensive statement of the scientific grounds for evo- | lution as applied to man. It does not deal with religious controversies, and is scientific throughont. The work is unique in design, which is =" carried out with the highest degree of Haeckel’s literary and artistic skill. Haeckel has always been distinguished for pressing the combination of the evidence from embryology with the evidence of zoology and paleontology. In the present work he devotes one volume broadly to embryology, or the evolution of the individual, and the second to the evolution of the human species, as shown in the comparative anatomy, zoology and paleontology. The last few chapters deal in detail with the evolution of particular organs right through the animal kingdom ; the eye, ear, heart, brain, ete. Every point is richly illustrated from Haeckel’s extensive knowledge of every branch of biology and his well-known insistence on comparative study. The work is written for the gereral reader, all technical terms being explained, and no previous knowledge being assumed ; but the scientific reader, too, will find it a unique presentation of all the evidence for man’s evolution and especially as a study of embryonic development in the light of race development. In the latest (fifth) German edition, to which Haeckel gave six months’ hard work, the plan is carried out with great skill, and the illustrations are very fine. All the most recent discoveries in every branch of science involved are included. It is a thoroughly up-to-date, non-controversial, most comprehensive and scientific treatise on the evolution of man by the greatest living authority on the subject. The English translation is in two volumes, and aims at being especially clear and useful to the general reader. It contains 30 beautiful plates (most by Haeckel and generally colored) and 512 engravings (very many full pages) and 60 genealogical tables.

ALBERT BENJAMIN PRESCOTT. Dr. ALBERT BENJAMIN PRESCOTT, di- rector of the chemical laboratory at the University of Michigan, died at his home in Ann Arbor, February 25, 1905. He was the senior member of the university faculty, and one of the veterans of American sci- ence. Dr. Prescott was born at Hastings, N. Y., December 12, 1832. Educated as a physi- cian, he took the degree of M.D. in 1864, and in that year and part of the year fol- lowing, he served as an assistant surgeon in the United States Volunteer Army. In 1865 he became assistant professor of chem- istry in the University of Michigan; was made full professor of organic and apphed chemistry in 1870; and was dean of the school of pharmacy since 1870; and from 1884 to the day of his death, was director of the chemical laboratory. His whole pro- fessional life as a chemist was spent in the service of the university, as teacher, organ- izer, administrator and investigator dur- ing a period of forty years. In a career like that of Dr. Prescott there is nothing sensational or spectacular. It was a life of obvious duties, uniformly well done, with nothing slighted, and no stri- vings after public recognition. Recognition, nevertheless, came to him unsought, and he had the satisfaction of knowing that his work was appreciated. He became presi- dent of the American Chemical Society, the American Association for the Advancement of Science and the American Pharmaceut- ical Association ; honors as high as any that American scholarship can confer. From 602 the University of Michigan in 1896 and from Northwestern University in 1903 he received the honorary degree of LL.D.; in 1898 he was made a member of the Ameri- can Philosophical Society; and in 1904 he presided over the section of organic chem- istry in the International Congress at St. Louis. The list of honors might be length- ened, but these examples are enough to show the esteem in which Dr. Prescott was held by those who knew him best and were most competent to appraise his merits. As a teacher Dr. Prescott was singularly successful, both in his personal relations with his students and as an organizer of reforms. He began his work at a time when lectures and recitations were com- monly thought to be adequate instruments for scientific teaching ; and when laboratory practice for students was a questionable novelty which only a few American schools had dared to try. From the beginning he took his stand on the side of modern methods, and organized his work along practical lines. The teaching of chemistry in schools of pharmacy and medicine was notably advanced through his efforts; and given a significance which, in this country at least, it had not had before. In this respect Prescott was one of several leaders; less conspicuous, perhaps, than some others, because of his modesty and quiet ways, but none the less potent and influential. He labored unpretentiously, but the results which he sought to accomplish were at- tained. The admirable organization of chemical work in the University of Mich- igan is the outcome of Prescott’s broad and liberal views. No man ean eseape the influences of his environment. The work that comes to him is the work that he must do. In Dr. Pres- cott’s ease, the requirements of his position with respect to medicine and pharmacy, naturally foreed him into the study of or- ganic compounds, but not along the con- SCIENCE. [N.S. Vou. XXI. No. 538.8 ventional lines. Theoretical problems oc- — cupied little of his attention; but analytical — methods, especially in the domain of toxi- — cology, and the investigation of proximate * | principles, such as the alkaloids, took a large part of his time. His researches upon | the alkaloidal iodides, and upon the assay 7 of opium, placed him easily first among American specialists in that class of stud- jes. His ‘Outlines of Proximate Organic Analyses,’ published in 1875, was the first text-book of its kind in the English lan- guage, and it brought him an extended reputation. In the same year he published a monograph upon ‘The Chemical Exami- f nation of Alcoholic Liquors,’ which made ; . him still more widely known. In 1888 he — issued a ‘Manual of Organic Analysis,’ | and he also contributed a fair amount to 4 the general literature of analytical proce — esses. Douglas and Prescott’s ‘Qualitative Chemical Analysis’ has been a standard text-book for thirty years. Dr. Prescott’s position in a state uni- versity naturally brought him into publie service in connection with sanitary affairs. The adulteration of food and the detection of foreign fats and coloring matters in butter were subjects to which he gave much { attention, and in which he was of material assistance to the food commissioners of Michigan. Questions of water-supply and filtration were often submitted to his judg- ment, and in these ways his public useful- ) ness extended far beyond the limits of his ; , state. Unfortunately, work of this kind brings little glory to a man, but its value must not be underestimated. It contrib- utes greatly to the public welfare, and it can be properly done only by one who is ~ thoroughly faithful and conscientious. Such a man was Prescott, whose work was honest from beginning to end. Dr. Prescott early recognized the value of research as a means of education, and so his students often shared in his investiga- Aprit 21, 1905.] tions. treated for the destruction of algz. But there is so much evidence in favor of the harmlessness of copper that it is impossible to even refer to it here. After all, it should be borne in mind that it is not a question of an absolutely pure water as compared with water containing a small amount of copper. It is typhoid- or cholera- or algx- laden water versus copper water. When the efficiency of copper for the destruction of alge had been fully demon- strated, it became a matter of interest, at least, to determine the effect of this metal upon typhoid, cholera and similar disease germs often conveyed by water. As the result of a large number of experiments we were able to determine that while copper was not quite so toxic to these pathogenic bacteria as to alge, still the results were sufficiently satisfactory to make it seem probable that, under certain circumstances, the method might prove of considerable value for the rapid and efficient steriliza- tion of large bodies of water. The conditions governing pollution by alge and bacteria are, of course, very dif- ferent. ‘Furthermore, there are methods already in use, which, if properly applied, Aprit 21, 1905.] SCIENCE. 607 will remove germs from water, whereas copper, is the only means thus far known which accomplishes the desired effect with algee. _ It should be most clearly understood that it was not supposed for a moment that the copper method could be substituted for effi- cient sand filtration or any other means now in use which has been demonstrated as doing the work thoroughly. It was be- lieved, however, and practical tests since made have proved it, that in cases where no system of filtration existed, or where the filter failed, owing to the storage basin be- ing flooded by surface drainage, or because of leakage or other cause, this method was not efficient, that in copper sulphate we had the only remedy for such emergency cases. It should be borne in mind that nothing is more delicate or requires more intelligent and conscientious supervision than a filter plant. Any one who has had an oppor- tunity to visit many such plants through- out the country and really knowing their inside workings, as it were, can not help being astonished at the low rate of efficiency frequently maintained. Consequently, the application of copper sulphate under such circumstances for the purpose of reducing the bacteriological content has been used successfully in enough cases to demonstrate that it has a distinct place in water purifi- cation. Whether it would be efficient and proper to use copper continuously during a considerable period awaiting the completion of a filtration system, is a question to be _ decided by the conditions governing the case. There is no doubt in my own mind _ that under certain circumstances such use is would be justified, and the results would 4 more than repay any outlay of money and | labor. _ Others will discuss more particularly the _ effect of copper upon typhoid, ete., so it is _ hot necessary for me to refer in detail to _ the work carried on by the department along this line. One other point regard- ing the effect of copper when used upon a practical seale is of interest, however. That is, that the theoretical strength, or the amount of copper used to destroy alge and bacteria in the laboratory, is considerably greater than the amount needed on a prac- tical seale. This may be due to the fact that the organisms used in laboratory tests are of necessity more resistant than those occurring under natural conditions; at any rate, results show that where it may require one part in a million of copper to destroy certain alge under experimental conditions, it only takes one tenth or even less than this amount to accomplish the same result in a reservoir containing millions of gallons of water. Dr. Henry Kraemer, Philadelphia Col- lege of Pharmacy, said: The purification of water supplies containing pathogenic organisms being a subject of such vital im- portance, it seems to me that any method proposed for this purpose should receive careful consideration, not only at the hands of water engineers, water companies, health officials and physicians, but by all those who are in a position to test the method, or contribute information regarding it, or to foster a sentiment in favor of it if found to be efficient. It was in this spirit that I undertook to test the method proposed by Dr. Moore and Mr. Kellerman. On account of the false sentiment which had been engendered in Philadelphia with regard to the purification of water by means of copper, and recognizing that the city authorities would not be apt to apply the method so long as there was this preju- dice against it, I determined to consider the method in relation to its application for household purposes. It is, of course, manifestly impracticable for the average householder to use copper sulphate in the purification of drinking water, and my experiments have, therefore, 608 been mostly with metallic copper. I first tried to obtain copper vessels for my ex- periments, but finding that I should have to wait some time to have these made, those on the market being tin-lined, I decided to use copper foil instead, which perhaps is fortunate, as this is more convenient and less expensive. In my earlier experiments I had a num- ber of my students in bacteriology carry on the work, using pieces of copper foil about 25 centimeters square to each 2,000 e.c. of water, allowing this to stand from four to eight hours at room temperature, the copper foil being cleansed with pumice for each operation. Agar plates were made and it was found that there was a reduction in the total number of organisms of from 85 to 97 per cent. For some time past one of my special students has been carrying on this work under my direction, and I may say that in all of those experiments where copper has been used the reduction in the number of organisms has been equivalent to what would be obtained by an efficient filtration system, with the advantage in the ease of the copper treatment that the or- ganisms are completely destroyed. In filtration processes it is generally understood that both typhoid and colon organisms are the first to be eliminated, and without waiting to complete a systematic study of the organisms which persist as well as those which are killed in the copper treatment of water, I thought it well to test the method by using water containing these organisms alone. Inasmuch as results depend in some measure upon the method used, I will try briefly to outline my method before giving my results. 1. Water under three different condi- tions was employed: (a) Distilled water, which was prepared from tap water by first treating it with potassium permanganate and then distilling it two or three times by SCIENCE. [N.S. Vou. XXI. No. 538. means of apparatus constructed entirely of glass. (b) Filtered tap water, prepared by means of a Berkefeld filter attached to a copper spigot. (c) Tap water collected after being allowed to run through a copper spigot for five minutes. All of these were sterilized in an autoclave at 110 degrees for thirty minutes. 2. The cultures of typhoid and colon which were used were pure cultures de- veloped in bouillon for eighteen to twenty- four hours. 3. To 200 ¢c.c. samples of water prepared as above, and contained in sterile Erlen- meyer flasks, were added two three-milli- meter loops of the fresh bouillon cultures of typhoid and colon bacilli, respectively. Counting the duplicate experiments pro- vided for, we thus had a series of twelve flasks, six of them containing typhoid ba- eilli, and six colon bacilli. 4. For studying the number of organisms 1 cc. of the respective solutions was trans- ferred directly to a Petri dish by means of a sterile 1 cc. pipette, and to this was added 10 ¢.c. of Heyden’s nutrient agar which had been kept at a temperature of 40° C. for some time. Three separate plates of the water in each of the twelve flasks were made immediately upon the addition of the cultures, and both the plates and the flasks were kept at a temperature of 35°— 37° C. To six of the flasks were then added strips of copper foil about 15 mm. wide and 18 em. long, these being corrugated in — such a manner that the entire surface was exposed to the water. 5. Plates were made from all the twelve flasks at the end of four and eight hours, and one, two and six days, even in the cases where no organisms remained, and in the cases where they continued to develop, at the end of fourteen, twenty-one and twenty- eight days. The results are given in the following tables: i Apriy 21, 1905.] TABLE I. EXPERIMENTS WITH BAcILLUs Cott. Water without Copper Foil. SCIENCE. Triple Filtered Distilled Tap Tap Water. Water. Water.

UNIVERSITY AND EDUCATIONAL NEWS. Tue cornerstone of the library building of Leland Stanford Junior University was laid on May 15. The building will cost $800,000. At the ceremonies an address to the students by Mrs. Stanford was read. In it she makes the amount. realized from the sale of her jewels, which are estimated to be worth $500,- 000, an endowment fund for the library. Grapuates of Yale University have arranged to purchase for the university the Hillhouse 840 estate, containing thirty acres and costing $510,000. This purchase fixes definitely the direction of Yale’s growth northward beyond the present site of the Sheffield Scientific School. Ir was announced at the meeting of the Yale Corporation, on May 15, that a gift had been received by Yale from a Harvard graduate—whose name was withheld—for the purpose of cementing the good feeling between the two universities. The use of the fund was left entirely to the Yale Corporation, which has voted to expend it for securing from time to time lecturers from Harvard to speak before the students of Yale. President Eliot, of Harvard, has accepted the corporation’s invitation to be the first lecturer. Tue University of Indiana has been granted $100,000 by the state legislature for the erec- tion of a new library. Work is about to be started on the new sci- ence hall of Colby University, which will be erected at a cost of about $90,000. Dr. D. K. Pearsons, of Chicago has made a gift of $50,000 to Montpelier Seminary at Montpelier, Vt., which he attended, conditional upon the institution raising $100,000 within a year. Ar the annual meeting of the National Academy of Design it was voted to accept the offer of Columbia University to form an affilia- tion. It is planned to collect $500,000 for a building, which will be erected on a site fur- nished by Columbia University. Tuer University of North Dakota will open a medical college in the autumn of 1905. Until the clinical advantages are adequate the medical course will extend only through the first and second years of the four years’ cur- riculum. Students who have completed the work at the University of North Dakota will be received into the junior year of the medical schools with which articulation is arranged. The Medical College at Bahia, Brazil, with its equipment and valuable library, has almost totally been destroyed by fire. Dusiin University has recently opened its degrees to women, and the first result has SCIENCE. [N.S. Vou. XXI. No. 543. been somewhat curious. Students who have done their work at Oxford or Cambridge may receive the bachelor’s degree at Dublin. As is well known, Oxford and Cambridge do not give their bachelor’s degree to women, and eighty-four women who had completed the work for the degree at these universities have received the degree from Dublin on the pay- ment of $50 each. Proressor AsapH Hatt, Jr., has resigned as professor of astronomy and director of the ob- servatory at the University of Michigan. Pro- fessor W. T. Hussey, of the Lick Observatory, has been elected his successor. Professor Hussey was graduated from Michigan in 1889. SaMuUEL J. BarNeETT, assistant professor of physics at Stanford University, has accepted the chair of physics at Tulane University, vacant by the resignation of Dr. Brown Ayres to accept the presidency of the University of Tennessee. THE department of physics in the Univer- sity of California has secured the appointment of Dr. A. S. King and Dr. A. W. Gray for the coming year, as instructors. Dr. King will continue the spectroscopic investigations on which he has published already a number of papers. Dr. Gray returns from the Univer- sity of Leyden, where he has been working in the cryogenic laboratory, to a ‘ Research In- structorship on the Whiting Foundation,’ sup- ported from the income of the bequest of Harold Whiting, formerly associate professor of physics in the University of California. Ar Williams College, Mr. William E. Me- Elfresh has been promoted to the Thomas T. Reed professorship of physics, and Mr. Herd- man L. Clelland to a professorship in geology. Dr. E. B. Hour has been appointed assistant professor of psychology at Harvard Univer- sity. Dr. A. R. FERGUSON, senior assistant to the professor of pathology in Glasgow University, has been appointed professor of pathology in the Medical School, Cairo. Tue council of the Linnean Society of New South Wales has appointed Mr. Harald I. Jensen to be the first Linnean Maclay fellow. SCIENCE.—ADVERTISEMENTS.

THE MACMILLAN COMPANY, Publishers, 64-66 Fifth Ave., New York JOURNAL OF PEDAGOGY ESTABLISHED IN 1887 An Educational Magazine of interest to all serious students of education. Some of the ablest contributions now being made to educational literature are appearing in the JouRNaL oF PeEpacocy. A REPRESENTATIVE OPINION “Tn building up the occupation ot teaching till it becomes a true profession, no magazine is rendering more significant and vital service than the JOURNAL OF PEDAGOGY, which admirably displays the interest of the editor in the science and art of education. Its articles have always been noteworthy for their Strength and freshness; its book reviews have been conspicuously valuable, exceeding in number those of the several other leading magazines combined. No field of educational effort has been neglected ; and there has been a reason- able apportionment of space alike to the university, the high school, the elementary school, and the kindergarten. Those who are earnest for the better- ment of American education view with the greatest seriousness the endeavor of such a magazine as the JOURNAL OF PEDAGOGY to represent the best thought and practice of the times, and by representing that thought and practice to encourage their influence. To publish such a periodical is a noble enterprise tor the welfare of American schools and of the American nation.’’—Dr. W. E. Chancellor, Superintendent of Schools, Paterson, N. J.

Y. THE PHYSICIAN OF THE FUTURE.* Tue day which marks the beginning of a career is always one of interest. Espe- cially is this so for him whose career begins, if indeed a career can be said to have definite commencement. But little less of interest, however, is felt also by his friends, and the day partakes of the nature of an Inauguration or a marriage. It is a gen- eral day of rejoicing. The graduate him- self is happy in the thought that his labors, at least for the time being, are over; his friends are glad to see the honor which he has earned, and the general public takes almost the same interest in the graduate that it does in the lover. This particular occasion, when those who have completed the prescribed course of medical and dental science present them- selves to receive their degrees, is of especial interest. This probably marks the last commencement of the medical and dental school of old Columbian. More than three quarters of a century of achievement marks her suecessful career. Thousands of graduates scattered throughout the land are proud of the alma mater who started them in life. The change of name, there- fore, to George Washington University is not looked upon with unmixed joy, espe- cially by the older children. A mother is, perhaps, no less a mother because, when widowed, she marries another man and takes another name. The academic mother * Address delivered before the graduating class of the medical and dental schools of Columbian (George Washington) University, Monday, May 30, 1904. 842 of this widely scattered and numerous family need be no less loved, no less cherished and no less helpful than under her old name. There are some of the arts which are nearer to the welfare of man than others, and the same is true of the sciences. There are two arts, however, which lie very near human welfare and if we were called upon to give up all of the arts but two, I think there would be little difference in choice as to which two should be preserved. The one most important would be the art of agriculture and the next the art of healing. Man first of all must be nourished and next to this, kept in health. We might look forward to a time when lawyers would disappear. We might even grow so perfect as to be able to do without ministers of the gospel. Even the. his- trionic art might be abandoned, and yet mankind be reasonably happy. But strike down agriculture and you strike a blow which is fatal; banish the healing art and you leave man to the ravages of disease. It is, therefore, probably not without some fitness that you have asked a ‘farmer’ to deliver this address, and it is quite becom- ing that on this occasion Ceres and Hygeia should be seen hand in hand. The man who receives his degree believes he knows something and the puble sup- poses that his belief is well founded. The amount known, however, or supposed to be known, varies greatly for different degrees. The college graduate, it has been said, doubtless supposes that he knows all things from A to Z, but the faculty and trustees, with a better idea of his accomplishments, give him only the degree A.B. If I re- member aright my Roman numerals an M.D. should know at least 1,500 times more than an A.B. Yet without doubt the de- gree M.D. or D.D.S. should carry a greater ballast of knowledge than the first degrees SCIENCE. [N.S. Vou. XXI. No. 544, of the academy. We may, with reason, doubt the propriety of conferring the de- eree of ‘doctor’ even upon those who have accomplished as much as you young men who are now before me. Doctor signifies ‘knowing,’ ‘learned.’ The physician should not—and perhaps no one should— bear this degree who has not added some- thing to the sum of human knowiedge. Some of the most famous surgeons and physicians of England ‘are only plain ‘mister’ and I fail to see where there would be any diminution in your skill if the degree which you receive to-night were ‘pachelor’ instead of ‘doctor.’ I am not quarreling, however, with the usual cus- tom, but mention this matter only to show you that bearing this degree you assume a responsibility of which you must strive to be worthy. The doctor is the teacher, the learned man, the knower as well as the doer. He is the man to whom people must come for knowledge, advice and inspira- tion. He is, moreover, the dua, the imperator in the empire of knowledge. Like the thirsting Omar Khayyam, each one should be able to say, ‘Myself when young did eagerly frequent doctor and saint and heard great argument,’ but the doctors and saints should be of better quality than in those medieval days, for in the present day we should not be com- pelled to add, ‘About it and about but evermore, came out by the same door as in I went.’ Health comes largely from good food and good hygiene, but one of the neces- sities to health is good mastication. Teeth are useful for other purposes than merely to improve looks, but even if they were only for this purpose they would be worth saving. Many a man has married @ beautiful set of teeth and, perhaps, after- wards discovered, to his amazement, that they were the fruit of dental science, but — a JUNE, 2, 1905.] you young men who have studied dentistry and have beeome proficient in the art should think the making of teeth to be the least of the purposes of your future life. As in surgery, dentistry is conservative, and you will serve man best if you will en- able him to keep the teeth which nature has provided. The physician of the fu- ture as well as the dentist must be the arbiter of good health, and good health eomes largely from good food and good hygiene; good food well masticated and good hygiene well applied. The farmer furnishes the food, the dentist secures its mastication, and the physician formulates the laws of health and helps to restore to the normal any dis- eased organ of the body. The first thing, therefore, which the physician of the future must see to is the food supply, not that he is expected to till the soil and produce its fruits, but that he is to help in the great work of restoring foods to their normal state. To what lengths have the arts of adulter- ation gone? There is no time to-night to preach to you about the awful evils of food adulteration, not only of its effect upon health, but of its demoralizing effect upon the honesty of commerce. It is a matter of which the medical profession of this country may be proud, namely, that as a unit they stand committed to the cause of pure food, to opposition to fake advertis- ing, to the restoration of honesty in the trade in food products, and to the elimina- tion from foods of drugs which are useful only in eases of disease. The great army of dentists also in this country stand in the same rank. They are aware, in fact, that if the functions of an organ are suspended the organ itself sooner or later suffers atrophy, loses its power of functional ac- tivity, becomes abortive in the course of ages and rudimentary. Thus the great SCIENCE. 843 professions of medicine and dentistry in the future will stand together to fight the evils of predigested and prechewed foods. Predigested food will cause the stomach to shrivel and become finally only a rudi- mental organ. Prechewed food will in the course of ages produce a toothless race. It is bad enough to lose one’s hair, but for heaven’s sake let us keep our teeth! I do not care who makes the laws in this country if you will let me furnish the people with good teeth, nor who writes the songs if I can help to keep the stomachs in prime condition. It will be a sad day for humanity in the future when pepsin loses its savor and is furnished only by the chemist and not by the secretory glands of the stomach. See to it then that future generations have something to chew and something to digest, and’ to this great end much of the energy and ardor of the in- vestigations of our future physicians and dentists must be directed. | The physician of early ages was a magician and necromancer. The medicine man of savage tribes is still practising the art of incantation. It is a far ery to Adseulapius, but before his day even dis- ease was supposed to be the work of evil spirits. In fact the most destructive swine plague that we read about in the Bible was caused by the devils which were east out of sick men, and these devils, taking posses- sion of the swine, caused them to rush into the sea and be drowned. The age of magicians in medicine was followed by that of the empiric, which was a great advance and led to the foundations of real science in medicine. The empiric we still have with us and always will have as long as man has idiosynerasies. We ean never tell in any individual ease what the result of any certain treatment will be because we can never properly estimate the value of the individual idiosynerasy. S44 Empiricism is one of the legitimate aids to science. A great inventor like Edison who wishes to find a certain property tries in logical sequence everything that is prac- ticable, and often it is only after thousands of trials that the substance having the requisite quality is found. So empiricism in medicine is legitimately applicable when guided by scientific reasoning and sound principles. The age of empiricism, however, was fol- lowed by the age of rationalism in medicine and it is on this basis that the science of medicine stands to-day. Perhaps I should not say science of medicine, but the art of medicine, because the art of medicine itself is based upon certain sciences, for instance, the science of anatomy, of physiology, of materia medica, of surgery. In fact there is not a science known to man which may not have some connection with the art of medicine. If we look at the physicians of the pres- ent we find three classes have been founded as a result of rationalism in medicine: First, the general practitioner who of neces- sity must be brought in contact with all forms of human ills; second, the specialist who happily lives in a community where the physician who devotes his whole time to one particular study can be supported; third, the health officer who is the fore- runner of the physician of the future. The foes of rational medicine at the present time are, first, the quack, a man possessing, possibly, high medical training and skill, but unfortunately devoid of those principles of ethies without which the hon- orable practise of a profession is impos- sible; second, the charlatan, a man neces- sarily devoid of any medical training or ability, who plays upon the feelings of his patients and administers nostrums of no value and applied with no science. The third foe of rational medicine is the imper- SCIENCE. [N. 8. Vou. XXI. No. 544. sonal physician, namely, the nostrum, the patent medicine and the proprietary rem- edy. It is appalling to think of the thou- sands and thousands of our fellow citizens who pin their faith to these alleged reme- dies. Some of them have value; they are in fact often the very remedies which are described in the materia medica and the pharmacopeia and administered by physi- cians, but distributed as they are, with absurd claims of efficiency, taken as they are, without the advice or consent of a physician, they become not only one of the greatest foes of rational medicine, but one of the greatest dangers to the public at large. I do not deny to the inventor who dis- covers a new remedy or a new combination of remedies the same right to profit there- from which is accorded to the inventor of a new machine or a new process. The law protects the inventor of such a remedy and he can protect it by patent or by trade- mark, but it seems to me there is no excuse for the secret nostrums and no justification for the methods of advertising them. I know how difficult this problem is; I know what vast returns are received by the pub- lie press for advertising these bodies; I know how valuable the press is and I ap- preciate the great and good work which it does, but there is no justification for using the columns of the public press to deceive the public, to excite fears of dangers that do not exist and create hopes that can never be realized. The physician of the future will see a growing preponderance of preventive medi- cine and the character of the profession in future years will be largely molded by the influence which this growth exerts. The activity of preventive medicine will be shown first in the case of public and domestic hyg:ene. The laws of good living are fairly well known to but few people. June 2, 1905.] The public schools will surely become a medium of transmitting instruction in this line. Public sanitation in the course of its eareer may reach that abomination of con- trivances in so far as offended hygienic conditions are concerned, namely, the sleep- ing car. It is difficult to imagine any con- trivance which human ingenuity could con- struct better caleulated to secure the best conditions for disease and the best methods for propagation thereof than the sleeping ear. Constructed in such a way that ven- tilation is practically impossible; parti- tioned into small compartments, carefully curtained to prevent any circulation of air, if there should be fresh air; provided with enough heating surface to the cubic yard to complete the installation of a Turkish bath, and manned by porters to whom high temperature is an evidence of heavenly bliss, it is not difficult to conceive of the tortures to which the helpless passenger is exposed. These compartments often carry, without any precautionary inspection, per- sons in all stages of phthisis and even other contagious diseases. There is no health officer to inspect Incoming passengers, no provision of the law requiring complete fumigation and no systematic appliance of any kind to prevent or eradicate disease. It has been claimed that the blankets are washed at least twice a year, as if that alone were a sufficient excuse for all of the dangers that exist! Perhaps, if one used the same blanket himself all the time he might not be justified in objecting to such frequent ablutions, but what right have we to ask if such a careful purification of a blanket used by a different person every night is based on any of the broad prin- ciples of hygiene or good taste? The composition of the air in a sleeper filled with passengers, after a night of low temperature can better be imagined than described. It is true that no one is com- SCIENCE. 845 pelled to spend the night in these ecompart- ments, but the ordinary coaches are not much less objectionable, and thus the traveler is left only with the option of staying at home or walking to his destina- tion. The physician of the future will gradu- ally teach the people the principles and necessity of public and private sanita- tion, for domestic hygiene is no less impor- tant than public. That dread scourge of humanity, consumption, will find its most effective foe in the establishment of true principles of hygiene both at home and in public places. ‘ The medical profession of the future will also see extended and placed upon sounder scientific foundations the antitoxin theory of prevention and cure. The world owes a debt of gratitude to Pasteur and his co-laborers in this and other countries for establishing the foundation, on broad scientific grounds, of the idea that im- munity may be artificially, as well as nat-. urally, produced. Jenner was the fore- runner of this great school of medicine, but his practise was absolutely empirical. Neither he nor his followers had any idea whatever of the manner in which vaccina- tion renders the subject practically im- mune to smallpox. Advanced medieal sci- ence has revealed the fact, however, that not only smallpox, but many other deadly diseases owe their toxic development to the compounds produced in the system chem- ically allied with the nitrogenous constitu- ents of the body. The moment these poi- sons become dominant in the system nature makes an effort to eliminate them or to neutralize them. In other words, the toxic body is met and combated by the antitoxic body. One of the greatest triumphs of the science of chemistry has been the deter- mination of the character both of toxic and of antitoxie substances and the development 846 of the method of producing them both, es- pecially the antidote. You have been fully instructed in the principles of this modern branch of medicine and know how closely your future professional activity will be connected therewith. Perhaps it is not wise to prophesy a time when enzymic diseases shall lose all their terror by reason of the discovery of ef- fective antidotes to the poisons to which their ravages are generally due. It is rea- sonable, however, to look forward to the time when the terror of these diseases, namely, diphtheria, typhoid fever, typhus and kindred scourges shall be reduced to a minimum. If, as has been well demonstrated, the germ of typhoid fever is transmitted prin- cipally in water, there seems no reason to doubt the ability of health officers, collabo- rating with broad-minded municipal au- thority and high class engineering skill, to perfect means whereby this deadly germ shall be practically eliminated from our water supply. Consumption may be checked by the establishment of camps of detention where the unfortunate victims of this terrible disease may receive not only the highest degree of proficiency in medical treatment, but also be so segregated from the non-infected portions of the community as to render the spread of the disease diffi- cult. Moses himself was a sanitarian of no mean accomplishments and many of the principles established by him in sanitary science might well be exploited in modern times. The type of camp which he estab- lished for the detention of unfortunate lepers, well modified to suit modern prin- ciples, would serve for the check and prac- tical elimination of consumption. I realize vividly the effect of a mental nature produced upon people of highly sensitive constitutions and of an impres- SCIENCE. sionable nature, such as the victims of phthisis usually are, in being made prac- tically prisoners in an environment of misery and despair. This, however, is not a question of sentiment, it is a principle of existence. It is based upon the undoubted right of the healthy to be protected against the invasion of disease. Moreover, a deten- tion camp might be made attractive in every way with beautiful gardens, sun- shine, flowers, music and all the other agreeable arts of life, and thus the terrors of detention be robbed of their chief sig- nificance. The physician of the future will, there- fore, be the herald and exponent of pro- phylaxis. It seems a contradiction of terms to predict a future for a learned pro- fession, which, if perfected, would rob the profession of all of its emoluments; but with the changed condition of the future physician a change in the character of his emoluments will also come. The medical profession, in other words, will not be paid in proportion to the amount of sickness - which prevails, but rather in proportion to the degree of health which is maintained. That physician will have the largest com- pensation whose parish is freest from dis- ease. He will become the teacher of the principles of public hygiene, as before men- tioned, in the schools, colleges and hos- pitals; he will, in my opinion, become largely a public officer, and every state, city and town will have as one of its chief offi- cials a medical health officer. Surely such an officer is quite as important to the wel- fare of the community as the assessor and tax collector. The physician of the future, therefore, will become more and more active as a citizen and take a more lively interest in public affairs. I have looked carefully over the congres- sional directory of the Fifty-Seventh Con- eress and find that the congress of the [N.S. Vor. XXI. No. 544, a I NI JUNE 2, 1905.] United States contains 319 lawyers, 93 business men, 32 politicians, 12 editors, re- porters and newspaper writers, 8 farmers, 3 teachers, 1 clergyman, 1 military man and 38 physicians. Does it not seem strange that the great law-making body of our country should contain so few mem- bers of this learned profession? Think for a moment of the amount of legislation in which sanitary matters are involved! It is acknowledged by all that the building of the Panama Canal is more a sanitary prob- lem than it is an engineering one. The men who really build the Panama Canal will be the physicians and health officers who eliminate from that infected locality the germs of malaria and infectious dis- eases. If the canal fails it will not be for lack of dredges nor shovels nor picks nor machinery nor money; it will be due to the ravages of cholera, of yellow fever and of other malarial diseases. The importance of the quarantine serv- ice has not been fully recognized. The exclusion of disease is the easiest way to fight it. The splendid work of the Publi Health and Marine Hospital Service is one of the things which the national legislator should carefully support. The legislation relating to pure food is a matter of the utmost sanitary importance. The regulations of interstate commerce which omit the sanitary conditions which have been previously outlined are alto- gether incomplete. In fact it appears that a very large proportion of our legislation which really concerns the public welfare should be accomplished with the advice, the vote and consent of the medical pro- fession, and yet out of more than 400 mem- bers of the national congress only three have had any medical training. The con- gress of the future will contain not less than 1 per cent. of trained medical men, but let us hope as much as 25 or 30 per SCIENCE. 847 cent. Again, there is no reason why a medical training should unfit a man for other duties in connection with public life than those relating to sanitary measures. I can see no reason why a physician should not make a good president as well as a good major general, a good governor or a good mayor, a good member of the common council and especially a most excellent commissioner of sewers. We wish the fu- ture to see the entry of medical men into public life and the assumption by them of all duties of a nature which relate to the public welfare. I can see no reason why lawyers should predominate in our national congress any more than that physicians should hold the. balance of power. Perhaps I can not better illustrate this idea than by quoting from that master of political craft, that learned and erudite statesman, ex-Senator David Turpie, who says in his book, entitled ‘Recollections of My Own Times,’ in speaking of Senator Dr. Gra- ham N. Fitch: Fitch was the only physician who ever served from Indiana in the United States Senate. I have latterly reflected somewhat upon this solitary instance. Years ago we used to send a good many of our physicians to Congress. He, himself, was one of these, and there were several others, among whom I recall Dr. John W. Davis, of Carlisle, in the county of Sullivan, whom I knew quite well. He was the first Indianian chosen to the position of speaker of the House at Washington and was accounted the best parliamentary jurist in the country, perhaps in the world. His rulings were quoted as authority in the English House of Commons and more than once in the legislative chambers of France. Upon his voluntary retire- ment from Congress he was appointed minister of the United States to China; served with distinction among the polished diplomats of the Orient, and returned to accept the appointment of governor of Oregon. He was the first American civilian of official note and station to make the trip home- ward from the east by way of the Pacific. His voyage across the ocean lasted several weeks. I have heard that the account of it, then no twice- told tale, was a story of thrilling, almost tragic interest. 848 In these later times our practitioners of the healing art seem studiously to avoid the cares and labors of political life. Occasionally you may meet a physician in the legislature—even this, as some of their caste say, is unprofessional—but as a body they appear to prefer the position of out- fielders in this arena. There are two notable characteristics of the active and skilled physi- cian—a close observation of detail and a deft attention to the matter in hand—the duty of the hour, of the moment. These qualifications are admirably suited to the requirements of public life. No more favorable hope can be expressed for the future than that the members of this great profession will again resume an active interest and prominent position in the political affairs of the state and nation. The physician of the future will have no easy berth, for, in his profession, as in all others, fitness, tact, erudition and in- dustry must win the way. The sluggard, the ignoramus and the indifferent must fall by the wayside. The number of people entering the med- ical profession is probably too great. In the United States of America, including the Philippines, Porto Rico and Hawaii, there were in 1901, 115,222 physicians in a population of 84,332,610. The last com- plete data we have concerning the number of attendants in medical schools are for 1899. In this year there were, excluding graduate schools, 156 medical schools in the United States with 24,119 students. The growth in the number of medical stu- dents in twenty-one years has been 142 per cent. In addition to these undergradute schools there are eight graduate medical schools which had (in 1895) 624 instructors and 1,813 students, of whom 59 were women. In Germany the conditions are quite un- satisfactory and the overcrowding of the medical profession in that country is a matter of grave concern. There are now in the empire 29,200 physicians, which doubles the number found in 1876. In other words there is one physician in Ger- SCIENCE. (N.S. Von. XXI. No. 544, many for every 1,700 inhabitants. In the city of Berlin 46 per cent. of all the physi- cians have an income of less than $700, and five per cent. of the whole number do not have a sufficient income to return it for taxation. On the other hand, in the iegal profes- sion in Germany 80 per cent. of the lawyers have an income exceeding $2,000. It is estimated that the preparation of a man for the duties of a physician in Ger- many costs about $6,000, and thus it is seen that the income is often less than 10 per cent. of the fixed charge on the capital invested. This leaves practically nothing for the reward of his own personal sery- ices, nor for wear and tear. What are to be the remedies for this condition of affairs in the future? Shall the physicians organize a union and admit only a certain number of apprentices each year, or shall they have the requirements for admission, when properly applied, ex- clude all those who are not extremely well prepared? In the- great school of the Beaux Arts in Paris the number of ad- missions is strictly limited and, perhaps, the great world school of medicine will have to come to this condition of affairs. In fact, an approach has been made al- ready in at least one great medical school of this country, and candidates for the degree of doctor of medicine are not ad- mitted until they hold a previous degree of an academic character or study equal thereto equivalent to the course of study required for the ordinary degree of bachelor of arts. The effect, however, which was anticipated in this particular instance was not realized. Indeed, there was at first a diminution in the number of students in attendance, but, attracted by the greater fame which a degree from such an institution would afford, this condition was gradually overcome and the actual } JunNE 2, 1905.] number of attendants became greater than when admission was easier. This is indeed a serious question. I doubt if the charge for medical services in the country can be much larger than $1.00 per head, and it is thus seen that the 115,000 physicians of this country must be content to divide among them a paltry income of less than $90,000,000 at the present time. Finally, the physician of the future will find his greatest service in prolonging hu- man life. JI am not here to claim that human life is so valuable that it needs always to be prolonged. This may not be so from the general economic condition of affairs, but, personally, I think we are all more or less interested in longevity. It ean not be denied that there is a distinct economical gain in putting a man out of the world after he has passed his prime and before be becomes a burden upon his friends or the community. The asylum and the poorhouse are not to be regarded as shining lights of advanced political econ- omy, but there is something in life besides mere political economy, and the prolonga- tion of existence is regarded as one of the chief functions both of the medical pro- fession and of public charities. On the other hand, it must be considered that there is a distinet economical loss in eutting off from existence a man before he has run the full course of his career. To train a man for usefulness requires now fully a quarter of a century, and it seems onty fair that he should have at least twice that time for the manifestation of his ac- tivities. If, therefore, he be cut off at thirty-five, forty or forty-five, the com- munity is robbed of service to which it is entitled. If old age could be secured without much of the burden now attending it, there would be the gradual ripening and mellowing of SCIENCE. 849 all the functions of the body and mind. If, in short, the human organism could be so constructed and eared for that it would continue its functional activity like the wonderful ‘one hoss shay’ until the time of its final dissolution, such a consumma- tion is devoutly to be wished. The medical profession of the future will find its best exponent in the service of senectitude. An old age without illness or dementation, a ripening without decay, a completion of the functional activity without the breaking down of any organ are steps toward which the medical pro- fession of the future may well direct its energies. Death should not be regarded as a mis- fortune, but as an end, as a termination of a journey which has been filled with delight, as a rest for weariness which comes with the natural order of labor, as an euthanasia and not a dreadful disaster. _ H.

In an early stage of development (em- bryo of 7 mm. total length), each of the more ventral Malpighian corpuscles of the mesonephros is still attached to the peri- toneum by a neck of cells which sometimes possesses a lumen and constitutes a perito- neal funnel. There are usually four, some- times three, such Malpighian corpuscles in each somite. A peritoneal ingrowth arises either directly from the base of each peri- toneal funnel or just mediad of it. These ingrowths are termed funnel sex-cords. Other sex-cords arise from the peritoneum between the funnel sex-cords and the mes- entery. These anastomose with the funnel SCIENCE. [N.S. Vou. XXI. No. 544. sex-cords which in turn unite with evagina- tions from their ¢orresponding Malpighian corpuscles after the latter have broken away from the peritoneum. The bridges thus formed between the funnel sex-cords and Malpighian corpuscles constitute the rete-cords which are thus formed from the distal portions of the funnel sex-cords plus evaginations from the Malpighian corpus- cles. The foregoing applies to the sex- gland along its entire length. The distal ends of all the funnel sex- cords and of many of the other sex-cords contribute to the formation of the adrenal bodies. The anterior portion of the sex-gland of the turtle is homodynamous with the rete region of the genital ridge of the mammals (pig and rabbit). Further Notes on the Chromosome Com- plex of Orthopteran Spermatocytes: C. E. McCuune, University of Kansas. A careful study of a large number of species indicates that the members of a family possess a common number of chromosomes. Im each species there is found a characteristic series of chromosome forms, and these are in many eases pecul- larly associated. In some cases the group- ing is characteristic of the genus, and within the genus the species are marked by variations in size of chromosomes and other parts of the cell. Heterotypical mitoses occur in spermatogonia, first spermatocytes, and second spermatocytes, and in each case witness a longitudinal division of the chromatin thread. In the spermatocytes all the chromosomes do not divide in the same manner. These irregularities of asso- ciation and division are largely due to the action of the accessory chromosome, which - in some eases unite with the one tetrad, forming a trivalent element, and in others with two tetrads, producing a pentivalent mutiple chromosome. From these observa- JUNE 2, 1905.] tions it is concluded that generic and specific characters are the result of differ- ences in size and associations of chromo- somes, and not to variations in numbers. It is also thought that continuous variation may be due to slight differences in size of the chromosomes of the germ cells, while discontinuous variation would be due to alterations in the relations of chromosomes to each other. Regeneration in Nudibranchs: C. M. Cup, University of Chicago. Several species of wolids abundant in the Pacific Grove region were used for experi- ment. It was found that removal of a portion of the body posterior to the middle was fol- lowed by rapid regeneration. The larger the portion removed the more rapid the regeneration. The ganglionic mass is situated posterior to the second pair of tentacles; removal of the whole head anterior to the ganglia was followed by rapid and complete regenera- tion. When the ganglia were removed no regeneration beyond healing of the wound occurred, though the animals often lived for two weeks. Regeneration of posterior portions of the body was less rapid in specimens from which the head anterior to the ganglia had been removed than in specimens with unin- jured head. The specimens from which the head region had been removed had lost their principal sense organs, but still re- tained the central nervous system intact. They were much less active than specimens with normal heads and the posterior parts were consequently subjected in much less degree to the conditions accompanying functional activity of this region; hence in all probability the less rapid regeneration. After the new head regenerated, posterior regeneration in these pieces was fully as rapid as in those with uninjured heads. SCIENCE. 851 Removal of other portions of the body such as the lateral regions of the foot, ete., had no effect upon the rapidity of posterior regeneration. If the animals are not fed a marked re- duction in size, often 50 per cent., occurs in the course of two or three weeks. The Relation of the Degree of Injury to the Rate of Regeneration: CHARLES ZELENY, Indiana University. Two series of the crayfish, Cambarus propinquus, differing only in the degree of injury which they had sustained, were com- pared with regard to the rate of regenera- tion of the right chela and the rate of moulting. In one series, AA,, the right chela was removed at its breaking joint. In the other series, BB,, both chelae were removed at their breaking joints and the last two pairs of walking legs were like- wise removed. Series 4A, comprised 36 individuals and series BB, 41 individuals. A comparison of the two series was made 95 days, 130 days and 153 days after the operation. In each ease the data show very definitely that the series with the greater injury molts sooner than the one with the lesser injury and also regenerates each of its two chele more rapidly than the latter regenerates its one removed chela.

The Sequence of Organisms in a Protozoan Culture and its Irreversibility: Amos W. Prerers, Zoological Laboratory, Univer- sity of Illinois. 852 A definite procedure is followed in the setting and eare of protozoan cultures with a medium of hay infusion. The seed here used came from previous laboratory eul- tures or from field collections. The physio- logical conditions are determined at almost daily intervals by physical and chemical methods. Evidence so obtained points to fermentative action as the beginning of metabolism in the culture. The curve for acidity is of much physiological signifi- eance. An approximate method of estima- tion is used to compare the relative abun- dance of the different organisms and the results are represented by curves. Rela- tive curves have been approximately deter- mined for bacteria, Colpidium, Parame- cium, Amaba, some Hypotricha, Arcella, some Rotifera and Stentor. All efforts to change well-defined curves to decidedly different relative positions in the history of the culture have failed. The maxima of the curves can not be interchanged by teseeding. tised (except for experiment) the cysts or spores of all the organisms found must have been continually present. Mutual antag- onism of the different forms is not a prob- able explanation. The serial succession of the organisms and the parallel physico- chemical changes in the environment point to specific adjustment as a probable hy- pothesis. The determination of some of the specific adjustments of Paramacium and Stentor supports this hypothesis. An Analysis of Physiological Conditions in a Protozoan Culture: Amos W. Prrmrs, Zoological Laboratory, University of Illinois. The influence of the physiological states of protozoa in producing variations from a supposed standard is seen in the results of experiments upon both the directional and the metabolie reactions of this group. To obviate this important difficulty the SCIENCE. Since reseeding was not prac- [N.S. Vou. XXI. No. 544. writer proposes to standardize the given conditions of any culture. Standardiza- tion of the conditions, if suecessful, uses the peculiarities of the physiological states for a more accurate interpretation of the re- sults of experiment, instead of leaving these states as objectionable factors in an experi- mental procedure. The methods to be used must conform to at least two conditions. First, they must not require more than a small amount of culture liquid (5 to 10 ec.) for a test, in order. that serial observations can be made upon the same eulture. Second, they must be sufficiently accurate and sensitive to yield results that show the successive small differences which occur in the history of a single culture. The special methods here applied are mostly volumetric and comprise the determination of: (1) Quali- tative chemical content, (2) free acidity or alkalinity, (3) dissolved oxygen, (4) bi- carbonates, (5) alkali earths, (6) electrical conductivity, (7) oxygen consumed, (8) sulphated nitrogen, (9) ammoniacal nitro- gen, (10) individual salts—nitrites, ni- trates, chlorides, potassium, calcium, ete. For both convenience and accuracy, a sys- tem of standardizing all the necessary volumetric solutions in terms of one orig- inal standard acid has been devised. By these methods one series of data has been taken from various media promiscuously selected for comparison, and another series comes from the history of single cultures. In both series the biological aspect of the media was known. Comparison of the physicochemical and the biological data in- dicates that variations in the former are an approximate expression for correspond- ing changes in the physiological states of the organisms. The methods here selected are therefore serviceable for the physio- logical estimation of the protozoan environ- ment. “ Ae eee ae ee ee ae — ee The Evolution of Cclor Characters: R. M. Srrone, University of Chicago. Color characters are purely relative means of distinguishing various individuals or groups of animals, and their significance varies according to the experience and knowledge of the observer. In birds, color characters are all connected by series of transitional stages which appear perfectly continuous even after careful analysis, and the most highly developed characters may be found in incipient stages not ordinarily observable. A study of the colors of birds has led the writer to believe strongly in an orthogenetice theory of evolution of color characters by continuous variation in birds. Some Observations on the Litoral Fauna of Pacific Grove, Cal.: C. M. Cutt, Uni- versity of Chicago. The Entomological Ecology of the Indian- corn Plant: S. A. Forses, University of Illinois. This paper consists of material in pure ecology selected from the mass of matter accumulated in the course of several years’ study of the corn insects from the economic point of view. It deals with adaptive rela- tions of the corn insects to their food plant and to one another; classifies adaptations of insects to their food as structural, physio- logical, psychological, local, biographical and numerical, giving illustrations of each class; discusses the adjustment by natural selection of the life histories of insects de- pendent upon the same plant; analyzes ex- amples of competition among such in- sects; refers to the agency of natural selec- tion in transforming competitions from the simultaneous to the serial order; and theorizes the whole subject by reference to the general principle of a community of interest between a phytophagous insect and its food plants. SCIENCE. 558 The Fauna of Mayfield’s Cave: ARTHUR M. Banta, Indiana University. Mayfield’s Cave is a small cave near Bloomington, Ind., which presents typical cave conditions having a nearly constant temperature and conditions of light shad- ing from twilight to absolute darkness. Eighty-seven species of animals were taken in this cave as against 68 heretofore known from all of the Indiana eaves. Of the 87 species but 21 are permanent residents and only 8 are found in eaves exclusively. Species including diptera, lepidoptera (2 species), arachnida and the bats hibernate in the cave in considerable numbers. Each cave inhabitant sustains a certain definite relation to the light, some living only in ab- solute darkness, others in dim twilight, ete. Aside from conditions of light and temper- ature, the distribution of eave animals is influenced by moisture, the presence of organic matter which serves as food and the presence of means of concealment. Some of the highly modified and truly ecavern- icolous forms are oceasionally found out- side of caves in springs, about wells, in drains and in similar situations. Change of seasons has little influence upon cave life. Species which are only temporary residents and some of the less highly specialized of the permanent residents are young and local cave forms, while the highly specialized cave inhabitants such as the blind fish, blind eray-fish and the blind earabids are old and widely distributed eave forms. The nearest relatives of cave forms are nocturnal or are dark or shade- loving species, while the food and habits of cave species are exactly similar to the food and habits of their near relatives living in other situations. The habit of hiding un- der loose stones and other debris persists in many cave forms where the habit is ap- parently altogether useless. Cambarus bartont living in the cave possesses less 854 SCIENCE. pigment, and their antenne are eleven per cent. longer compared with individuals of the same species living outside. Guinea-chicken Hybrids: MicHaru F. Guyer, University of Cincinnati. These hybrids, five in number, were pro- duced by crossing a black Langshang cock with a common guinea hen. When young the hybrids resembled more young guineas, although the shanks were feathered, as were those of the father. Traces of these feath- ers still (nearly three years later) per- sist. The hybrids are much larger than guineas and have louder and even more discordant voices. They are extremely wild. The head shows no trace of either the comb of the chicken or the helmet of the guinea, but is covered with feathers clear to the beak. Neither are wattles nor earlobes present. The beak, in color and shape, resembles more that of the guinea. A trace of the guinea’s white face is discernible in the hybrid in the immedi- ate region of the eyes. The neck is very long and snake-like. The feathers are more or less intermediate in structure be- tween those of the parent forms. The tail is erect and never droops like that of the guinea. The large quill feathers of tail and wing not infrequently possess vanes which are black on one side of the rachis and more like the hybrid general plumage on the other. The first one to three primaries are white in all of the hybrids. Guineas frequently show similar white primaries. The color of the head and neck is mainly black, although in two of the forms, there is a decided sprinkling of white feathers in this region. The general ground color of body, wing and tail plum- age is dark gray in three of the hybrids, but in the remaining two it verges more toward a chestnut color. In all, the feath- ers are crossed by narrow lighter colored V-shaped bars which gives the plumage, on [N.S. Von. XXI. No. 544. the whole, a decidedly barred appearance. The conspicuous white dot of the guinea’s plumage seems to be entirely lost. There is, however, a secondary inconspicuous barring in many of the features of the guinea which possibly may be the source of the bars of the hybrid. The forms have not proved fertile and the chief interest in them will center in the chromosomal structures of the germ cells. there is no means of telling their sex. Notes on Cross-bred Chickens: MicHaeu F. Guyer, University of Cincinnati. Barred or white Plymouth Rocks and brown Leghorns were used in crossing. There is much question regarding the ex- act ancestry of Plymouth Rocks, but un- doubtedly the American Dominique and the black Java are the main sources, with probably also a considerable admixture of Brahma blood. The brown Leghorn of to- day appears to be the descendant of an old breed of fowls introduced from Italy in 1834. ‘The offspring, 400 in number, of brown Leghorn 4 & Plymouth Rock 2 were every one black, except for an occasional feather of reddish hue in some of the cocks. While in plumage they thus seem to revert to the ancestral black Java, this is not so true of shape and weight, which varies in al! degrees between that of the two parent types. The white ear lobes of the Leghorn always persist. Some of the progeny, in- deed, resemble black Minoreas very closely. Most of them have the dark slate-colored shanks that commonly accompany black fowls, although about 30 per cent. are yellow shanked. The comb is the most variable structure, exhibiting 3 or 4 to 7 serrations. Not infrequently double combs (two single ones side by side) ap- pear in the cocks. Various crosses among the members of this generation and between them and the parent stocks were made, but At present . Eee JUNE 2, 1905.] the limits of an abstract will not permit record of these results. On the whole, no characters observed, appeared to follow the laws of Mendel with any accuracy. For example, black x black have invariably produced black offspring, so far with the white ear lobes persisting. A black J x barred plymouth 9, among others, pro- duced one male offspring which rather closely resembles a dark Brahma cock. Pure white Plymouth Rocks which al- ways produced white offspring when bred together, never produced white offspring when crossed either way with brown Leg- horns, nor did any of the mongrel off- spring, when interbred. The majority of the offspring were barred, the remainder being nondescripts or occasionally black. Interbreeding this generation resulted in the production of several fowls which were of a pure barred Plymouth Rock type ex- cept for the persistent white ear lobes of Leghorn origin. Observations on some Peculiar Habits of the Mole-crickets: W. J. BAUMGARTNER, Kansas University. The female of our northern mole-cricket, Gryllotalpa borealis, has quite a loud and distinct chirp. This seems to be used as a means of recognition in their dark burrows. This observation is contradictory to the conclusion of all writers who say only male orthoptera chirp, or stridulate. The fe- male of the Porto Rican species Scopter- iscus didactylus has the same kind of a stridulating organ (much smaller and weaker than that of the male) on its elytra, and so I econelude it also chirps. Du Four’s gland of ‘excretory secre- tion,’ which later investigators have con- nected with the copulatory organs, is by my observations and experiments shown to be an effective protective device. A strongly fetid and very sticky secretion is ejected with considerable foree from the siphon- SCIENCE. 855 hke genito-anal opening. This must repel or retard the most ardent pursuer and so protect the soft abdomen from the rear. In the act of copulation these insects assume the relative positions suited to their tunnel-like homes. They turn posterior end to posterior end and ventral side to ventral side, the male lying on his back. The sperm is transferred in a spermato- phore. Scopteriscus has a similar pro- tective gland, but its copulation was not observed. The chirping of the female, the protective anal secretion and the unusual position of male and female in copulation which dis- tinguish the mole-crickets from the rest of the orthoptera are very evidently adapta- tions to life in underground tunnels. The presence of the spermatophore accounts for the annexed glands in the male Gryllotalpa. The Reflex Theory of Orientation as Ap- plied to the Phototaxis of Ranalia: S. J. Houmes, University of Michigan. A Note on the Position of the Temporary Pharynz in the Planarian Embryo: W. C. Curtis, University of Missouri. Mattiesen in his extensive account of the embryology of the European Planaria torva, which has been recently published in the Zeitschrift fiir Wissenschaftliche Zoologie (704), suggests that my desecrip- tion of the orientation of the adult and embryonic pharyngeal structures in P. maculata must have been due to the exam- ination of a single abnormal specimen or. to distortion caused by poor fixation. My ob- servation has been confirmed by Bardeen (702) ; and in another American form, P. simplicissima, Stevens (’04) believes the same orientation to exist, although in this ease the early disappearance of the primi- tive or embryonic pharynx makes the mat- ter difficult to establish. Mattiesen finds that in P. torva the adult pharynx appears 856 SCIENCE. just behind the degenerating embryonic pharynx, which is, therefore, located on the future ventral part of the body as the spherical embryo becomes flattened. This confirms Ijima’s (’84) deseription of the orientation in Dendrocalum lacteum. In B. maculata the point at which the degen- erating embryonic pharynx is last seen is on the dorso-posterior surface. The Arrangement of the Mesenteries in the Cerianthide. J. PuAyFAIR McMurricuH, University of Michigan. In 1892 Faurot observed that the mesen- teries of Cerianthus membranaceus were arranged in groups of four, each quartet consisting of a longer and a shorter fertile mesentery alternating with a longer and a shorter sterile one, and his observation was subsequently confirmed by van Beneden for C. Lloydii. Both authors regarded the quartets as beginning with the fourth mesentery on each side of the mid-siphon- oglyphie line. The study of the develop- ment of the cerianthid mesenteries has shown, however, that the first four mesen- teries on either side of the mid-siphon- oglyphie line constitute a group distinct from the others and are comparable to the eight protoenemes of the other groups of Anthozoa. Among the ‘Siboga’ actinians is a species from Amboina, probably C. elon- gatus Kwietn. In this form there is on either side of the mid-siphonoglyphic line the usual short sterile directive mesentery, then follow two additional sterile mesen- teries, and then a long fertile mesentery which extends almost to the aboral pole of the body. This last is apparently the so- called continuous mesentery, and the inter- est of it lies in the fact that it is the fourth mesentery and not the second, as in all other species that have been examined. This departure, which occurs in all the in- dividuals of the species examined, corrobo- [N.S. Vou. XXI. No. 544. rates the view based on the developmental history that the four mesenteries on either side of the mid-siphonoglyphie line consti- tute a group apart from the rest, and that the quartets should be regarded as begin- ning with the fifth mesenteries. An Improved Form of Reconstruction Ap- paratus: THomas G. Les, Laboratory of Histology and Embryology, University of Minnesota. Doctor Lee presented a very satisfactory form of reconstruction apparatus, which he had designed and which is an improvement over the models now in use. It consists of a cast-iron bed plate 84 cm. (34 inches) thick at sides, and 44 em. (2 inches) thick in the middle. The top measures 23 x 30 em. (9x12 inches), and has been accurately planed and polished, giving an area of 690 sq. em. (108 sq. in.). The side pieces, by which the thickness of the wax plate is de- termined, are moved up an inclined plane which is rigidly fastened to the bed plate in a manner similar to the movement of the object holder in a Thoma microtome. All parts of the top of each side piece are thus always in the same plane. The side piece is moved up and down by a large and accurately made screw at the rear of the apparatus... After adjust- ment the side pieces can be firmly fixed in place by two set screws by means of a small wrench. A metal seale is placed on each side piece, so that any thickness of wax plate can be made from $ mm. up to 1 em. at $ mm. intervals. Thus plates of 3, 1, 14, 2, 24 mm., ete., can be made. Pro- jecting from the bed block are two metal strips with a depression to hold the roller when not in use. This whole apparatus weighs about 67 pounds, and is quite rigid. The roller is of polished steel 30 em. (12 inches) long by 6 em. (24 inches) diameter, with a steel rod projecting at each end and covered by a movable wooden handle. This sy RaSh acl ab et it ale Nether Hele ? ow “~< a _ ¥ JUNE 2, 1905.] roller weighs 17 pounds, but works very easily, indeed. The heating apparatus consists of a metal frame supporting a copper jacket which has a coneavity on its upper surface just a little larger in diameter than that of the roller. This protects the surface of the roller from contact with either the metal or flame. This coneavity could easily be changed into a hot water bath for the roller, if so desired. The lamp is a horizontal Bunsen burner tube with numerous small openings. _ The roller does not require to be heated between each pair of plates, and thus when not in use it is readily rolled up into the support in front of the bed plate. This whole apparatus is very solid, com- pact, accurate and easy to adjust. Some Abnormalities of Growth Produced by Parasites on Alcyonaria: C. C. Nut- TING, State University of Iowa. In their ‘Report on the Aleyonaria of the Challenger Expedition,’ Wright and Studer described a new genus, Calypter- mus, giving as a generic character a certain tunnel-lke structure formed by excessively enlarged spicules, the tunnel being along one side of the stem or branch. Later Studer, in reporting on the Aleyonaria se- eured by the Prince of Monaco’s yacht, de- clares that this peculiar structure is due to the presence of an annelid, and is patho- logical in fact. A similar structure was found by the writer in a species of Tenella secured by the Albatross from Hawaiian waters. The tunnel-like structures, with the annelids inside, were shown by means of lantern slides. In a new species of Dasygorgia from the same collection the writer found certain very greatly enlarged polyps which at first looked like a form of dimorphism hitherto unknown. Upon dissection, however, these monstrous polyps were found to contain, without exception, minute crustaceans, SCIENCE. 857 either embryos or some form of degraded parasite. These were also shown by means of lantern slides from photographs made by the author. It appears that we have here a condition of affairs in an animal organism which bears a close analogy to the production of ‘galls’ in vegetable tissues. The Origin of the Subclavian Artery in the Chick: Wm. A. Locy, Northwestern Uni- versity. (Based on the work of Mr. Sabin. ) The subelavian artery in birds lies ven- tral to the vagus nerve and vena cava; in mammals it occupies a dorsal position with reference to those structures. On this ac- count the subclavian arteries do not appear to be homologous as to origin in these two classes of vertebrates. ° Hochstetter was the first in 1890 to clear the question by show- ing that the definitive subclavian in birds is of secondary origin. Prior to its appear- ance there is a vessel arising from the dorsal aorta, opposite the 15th mesodermic somite, which supplies blood to the wing- bud from the third to the sixth day of development. On the sixth day the sec- ondary subclavian arises from the ventral end of the third aortic arch. This new vessel passes backward and joins with the primary subclavian artery, coming from the dorsal aorta, and, from the sixth to the close of the seventh day of development, the wing bud receives blood from the two sources. The primary subclavian then dis- appears and the secondary subclavian re- mains as the permanent one. Mr. C. G. Sabin, a graduate student in Northwestern University, has traced with great care the embryonic history of the subelavians in the bird and has illustrated the same. His results agree closely with those of Hochstetter, except that he finds the primary subclavian in earlier stages than Hochstetter, and observes that in the early condition the subclavian arises inde- 858 SCIENCE. pendently of the segmental arteries, with which, however, they join later. The illus- trations which Mr. Sabin gives of the actual condition of the developing subclavian ar- teries were very much to be desired, since Hochstetter’s paper was illustrated only by a few simple diagrams. The results are now published in the Anatomischer An- zeiger, Vol. 26, Nos. 11 and 12, with 29 illustrations. The following demonstrations were made before the society : 1. William A. Locy, Northwestern Uni- versity, ‘Dissections Showing the Nervus Terminalis in Scyllium, Trygon and other Selachians.’ 2. William S. Miller, University of Wis- consin, ‘Demonstration of the Lymphaties of the Lung and Stomach in Nectwrus.’ 3. Bennet M.

Tue April-May number of The Journal of Geology contains an article on ‘The Zuni Salt Lake’ of western New Mexico, by Mr. N. H. Darton. It is illustrated by two maps and three half-tones. Mr. Douglass W. Johnson reviews ‘ The Tertiary History of the Tennes- see River’ and concludes that it has followed its present course through Walden Ridge for a long time, ‘ probably since the close of the Oretaceous period at least.’ This article is illustrated by nine figures. Professor B. Shimek contributes an ‘ Additional Note on Helicina occulata, a recent species, which also occurs as a fossil in the loess, and con- cludes that it supports the view that ‘ during the deposition of the fossiliferous loess the climate was not glacial. Mr. Rollin T. Chamberlin describes ‘The Glacial Features of the St. Croix Dalles Region,’ which is il- lustrated by three sketch maps. Professor Stuart Weller describes ‘A Fossil Starfish [N.S. Von. XXI. No. 544. from the Cretaceous of Wyoming,’ which he names Pentagonaster browni. Mr. O. W. Willcox contributes an article on ‘The So- called Alkali Spots of the Younger Drift- sheets,’ which are patches of white efflores- cence which ‘consist of small amounts of sodium chloride and much larger amounts of the carbonates and sulphates of magnesium and calcium.’ Mr. George C. Matson has a paper on the ‘ Peridotite Dikes near Ithaca, N. Y., in which he describes several new dikes in addition to those noted over sixty years ago by Vanuxem and much more re- cently by Professor Kemp, and Mr. Wallace W. Atwood describes the ‘ Glaciation of San Francisco Mountain, Arizona.’ This article is illustrated by a sketch map of the top of the mountain and it is stated that these rec- ords ‘may possibly be those of the southern- most ice which existed in this country during the Pleistocene period.’ To the American Geologist for April Pro- fessor Eugene A. Smith contributes a ‘ Bio- graphical Sketch of Henry McCalley’ with portrait. Professor Warren Upham has an article on ‘The Nebular and Planetesimal Theories of the Earth’s Origin,’ in which he quotes at length from Dr. T. C. Chamberlin’s recent paper on the planetesimal hypothesis. Professor Upham also quotes from Dr. G. K. Gilbert’s paper on ‘The Moon’s Face’ and concludes that his explanation of the origin of the very abundant small and large crateri- form features of the moon seems largely iden- tical with Chamberlin’s hypothesis ‘so far as that hypothesis deals with the segregation of the originally nebulous matter to form planets and satellites.’ Professor J. W. Spencer re- views ‘Dr. Nansen’s Bathymetrical Features of the North Polar Sea, with a Discussion of the Continental Shelves and the Previous Oscillations of the Shore Line.’ Mr. Spencer says that while this memoir ‘treats of the physiographic features of the Polar basin, yet the greater part is devoted to the investigation of continental shelves, not merely of the Arctic basin, but also those of the Atlantie, in which respect it is the most important work that has appeared anywhere. ‘ Professor JUNE 2, 1905.] Shimek’s criticism of the aqueous origin of Loess’ is answered by Professor G. Frederick Wright. Mr. Paul W. Prutzman discusses the ‘ Chemistry of California Petroleum,’ and the number concludes with an article by Pro- fessor Lawrence M. Lambe, ‘On the Tooth- Structure of Mesohippus westoni (Cope),’ which is illustrated by one plate giving four views of an upper molar of this primitive species. The American Naturalist for March con- tains the following articles: ‘The Anatomical Changes in the Structure of the Vascular Cylinder, Incident to the Hybridization of the Catalpa,’ by D. P. Penhallow; ‘The Oc- currence and Origin of Amber in the Eastern United States,’ Arthur Hollick; ‘ Fresh-water Rhizopods from the White Mountain Region of New Hampshire, J. A. Cushman and W. P. Henderson; and ‘The Reactions of the Pomace Fly (Drosophila ampelophila Loew) to Light, Gravity and Mechanical Stimula- tion, by F. W. Carpenter. There are, besides, reviews of scientific literature. ARTERIOSCLEROSIS in its relation to diseases of the nervous system is the subject of the opening paper in the May issue of the Journal of Nervous and Mental Disease. Dr. EK. D. Fisher discusses the clinical aspect, and Dr. Harlow Brooks summarizes the pathology, with reports of three illustrative cases, one of syphilis of the cerebro-spinal axis, one of arteriosclerosis of the brain and spinal cord oceurring in alcoholism, and one of acute arteritis occurring in vessels of the central nervous system in rabies. Drs. W. G. Spiller and C. H. Frazier follow with the presentation of some original views on the subject of nerve anastomoses. They have experimented in this line in the treatment of cerebral palsies, and their suggestions open up a field in neurolog- ical surgery that seems to be full of promise. Dr. Spiller also contributes a short illustrated paper, being mainly the report of a case which came under his observation and seemed to offer valid evidence for the location of the fibers of temperature and pain within the tracts of Gower. Dr. Jas. W. Wherry writes SCIENCE. 859 on the curability of epilepsy, and takes an optimistic view of the question, conditioned on beginning treatment promptly upon the ap- pearance of the disease. His idea of the re- quirements in such treatment consists of ‘A study of each case individually; special adapta- tion of drugs to individual conditions; per- sonal supervision and individualization of diet, absolute change of environment.’ The pro- ceedings of the New York Neurological Society for December 6, 1904, and of the Philadelphia Society for December 27, 1904, are reported.

Davis, of Harvard University, gave an illustrated lecture on the Colorado Canyon, based upon four visits to the Arizona plateaus. He emphasized the origin of the canyon as a valley of normal erosion excep- tional only in depth, as shown fifty years ago by Newberry; its independence of the great fractures of the region whose course is us- ually north and south, as shown thirty years ago by Powell and Dutton, while the canyon is cut from east to west; and the record of a SCIENCE. [N.S. Vou. XXI. No. 544. long geological history magnificently displayed in the canyon walls. This history of the region was traced backwards, first stripping off the horizontal layers of the plateau series, next reconstructing, untilting and stripping off the now inclined layers of the so-called Algonkian ‘ wedge’ and then roughly building the lost mountains of the erystalline founda- tion rocks, commonly regarded as Archean but not yet demonstrated to be of so great an- tiquity. Having thus traveled backwards through the ‘ corridors of time’ to the earliest stage of geological history there recorded, the return journey was made along the normal succession of events. Six long ages of time, occupied alternately by deposition and by erosion, were thus reviewed: Three ages of enormous deposition, requiring a correspond- ingly enormous erosion elsewhere, and three alternate ages of enormous erosion, suggesting an equally enormous deposition elsewhere. The short chapter of canyon erosion was en- tered upon only after the long earlier ages were closed: thus a correction was suggested for the erroneous view that the erosion of a great canyon requires a long part of geological time. The apex of the Algonkian wedge and the associated ancient plains or peneplains of erosion, best seen from Grand View, sixteen miles east of the railroad terminus, were indi- cated as the points on which the attention of the inquiring visitor should be focussed. The voleanic history of the district, as associated with the erosion of the canyon, was briefly touched upon. J. EK. Kirxwoop, Corresponding Secretary. THE NEW YORK ACADEMY OF SCIENCES. SECTION OF ANTHROPOLOGY AND PSYCHOLOGY. A MEETING was held on February 27, in conjunction with the Ethnological Society. General Wilson occupied the chair. The fol- lowing papers were presented: ‘ Anthropom- etry of the Jews of New York,’ Maurice Fishberg. Whether the Jews have maintained their racial purity to the present day is a question that can be examined by comparing the physical type of Jew from different coun- tries. Extensive measurements of Jewish June 2, 1905.] immigrants in New York from various coun- tries of eastern Europe show that the Jewish type in those countries is not Semitic, but varies in the different countries, always ap- proximating, in stature and cephalic index, to the native or Christian population of the respective countries. ‘Anthropometric Work at the St. Louis Exposition, R. S. Woodworth and F. G. Bruner. As many as possible of the racial groups represented at the exposition were measured. The best material was found among the Philippine Islanders, of whom about 700 were measured. The Christianized tribes, such as the Tagalog, Pampango, Ilo- eano, Bicol, Visaya, were found very uniform in physical type. Measurements showed no clear evidence of differentiation among them. The average height of the several tribes dif- fered but little from 161 ecm., the cephalic index differs little from 83, ete. The Moros of Mindanao also are practically identical in physical type with the Christian tribes. The pagan Igorots and Bagobos seem to differ con- siderably from this type, especially in height, which is about 155 cm.; while the Negritos were clearly marked off from all the rest by their kinky hair, small stature (144 cm.), broad nose, and small head in proportion to stature. R. S. Woopwortu, Secretary. THE PHILOSOPHICAL SOCIETY OF WASHINGTON. Tuer 600th regular meeting, held April 15, 1905, was celebrated by historical addresses in University Hall of the George Washington University, followed by a social hour with refreshments. , After a brief address by President Little- hales, half a dozen papers were read giving a review of the activities of the society since its foundation in 1871, under the presidency of Joseph Henry, in the lines of most interest to its present membership. Mr. Gore grouped and characterized succinctly the papers pre- sented in mathematics. Mr. Wead reviewed the papers on physics, beginning with Henry’s “Aberrations of Fog Signals’ and including recent notable work on aerodynamics. Mr. Clarke told of the great local development of SCIENCE. 861 activity in chemistry since 1871. Mr. Gil- bert spoke of the opportunities the society had furnished to discuss questions in geology, in- stancing cases where the discussions had led to important researches. ‘Mr. Hayford re- called some of the notable advances in geodesy that had been presented to the society, Mr. Eichelberger reported on the papers in astron- omy and Mr. Bauer spoke of the activity in electricity and magnetism. A brief letter from Dr. Gill was read regarding the interest in biology before the formation of the other scientific societies. THE 601st meeting was held April 29, 1905. Professor W. S. Eichelberger exhibited one of the Riefler self-winding astronomical clocks belonging to the Naval Observatory and de- seribed its construction. It is in a case from which about one eighth of the air is ex- hausted; the pendulum is of nickel-steel alloy compensated ; the power comes from two small cells of battery and is applied about twice a minute. The rate is very small and very constant. Professor F. H. Bigelow then spoke on ‘Tonization and Temperature-Effects in the Atmosphere.” The great problems in meteor- ology relate to the vertical distribution and semidiurnal curve of temperatures; and to the variations in vapor tension, atmospheric electricity and magnetic field. A great num- ber of curves representing the results of ob- servations on the quantities involved in these problems were exhibited, and the attempt was made to explain the facts according to the modern theory of ionization. The paper will appear in the Monthly Weather Review. Cuarztes K. Weap, Secretary. THE SCIENCE CLUB OF NORTHWESTERN UNIVERSITY.

CONNECTION BY PRECISE LEVELING BETWEEN THE ATLANTIC AND PACIFIC OCEANS. To THE Eprror oF ScieENcCE: In your issue of April 28, 1905, page 673, is an article by Mr. Hayford on ‘Connection by Precise Level- ing between the Atlantic and Pacific Oceans.’ About twenty years ago I wrote to ScIENCE in connection with precise leveling over the Alle- ghanies and the Rocky Mountains, and stated that it might be well to have a systematic determination of bench marks at stated in- tervals owing to the unrest in the earth’s crust. At that time I stated that my work on the corps of the Pennsylvania Railroad had shown me that, however carefully the bench marks might be established at any one time, at the expiration of a comparatively few years there would be a discrepancy between them and the datum plane. The Pennsylvania Railroad has reviewed its bench marks a number of times owing to these discrepancies due to earth mo- * tion. tween the levels of the Atlantic and Pacific Oceans, unless the bench marks were estab- lished by surveys which began and ended at exactly the same period throughout the entire distance, might be due to earth movements between the times of the beginning and the end of the survey. I would again suggest, as I did at my first letter to this paper, that the United States Geological Survey secure not only the lists of bench marks of all railroads, but the varia- tions that have occurred in these bench marks as shown by repeated surveys. If these are carefully tabulated throughout a century, we may obtain important information in regard to the upward and downward crustal move- ments across the continent. Epwarp H. WIitiiaMs, gr.

In comparative studies of the skull it is customary to select one transversal plane de- fined by the axis of symmetry with which it is at right angles and by two points, as the standard plane to which the skull is referred. Some authors have made the selection of the two determining points based on morpholog- ical considerations, while others have en- deavored to determine the physiological hori- zontal position, determining the latter by two points which are more or less accurately par- allel to the direction of horizontal sight. When this problem is considered from a purely morphological point of view, it will be recognized that there is no justification in selecting arbitrarily two points and disregard- ing all others, but that the best method of comparison must be based on the assumption that every point of the skull has equal weight and that the nearest approach of all points must be attempted. In this form the problem is applicable to the comparison of all variable forms. The most favorable superposition of any two forms will be obtained when the sum of The want of agreement, therefore, bewe “the squares of the distances between all pairs of homologous points becomes a minimum. We will refer the body to a system of rect- angular coordinates and eall zw’, y’ and z’ the ordinates of a point of the first body, x”, y” and 2” the ordinates of the homologous point of the second body. By moving the second body by the amounts wu, v and w in the direc- tion of the three ordinates, we can modify the relative positions of homologous points with- out torsion of the body. Then the sum of the squares of the distances of homologous points S(a/ — a//— u)?+ S(y/—y’ — 0)e + >(2’—2” —w)? is to be a minimum. Therefore, >(a/ — a’ —u) =0. And JUNE 2, 1905.] Since we may assume the origin of the first system of ordinates arbitrarily, we may take 32! = Sy’ = 32’ = 0; in other words, we take the geometrical center of gravity of the first body as the origin of our system of ordinates. Then Sa’ = Sy” = Se’ =0; i. e., the two bodies must be so placed that their geometrical centers of gravity coincide. Provided the two forms are symmetrical, this result gives a complete solution of the problem. If the forms are irregular, the de- gree of torsion must be determined which will give the best result. In most cases the form in question will be symmetrical in at least one direction, so that torsion in one direction only need be considered. Starting with the geometrical center of gravity as the origin of a system of polar coordinates, we have for any given pair of points the coordinates I’ and 1” as distances from the center, and a/ and q@” as angles with the zero line. If we _ give the second system of points the torsion &, we find that >i? + V72— oI’ cos (é + a/’ —a’)} must be a minimum; or SVV’ sin (£ + a// —a’/) =0, SVU’ sin (a// —a’) SV’ cos (a// = a) § = Theoretically, the problem can, therefore, be solved. By using a limited number of well- selected points a good superposition of the two forms can be made. Experiments, so far as carried out, indicate that alveolar point, nasion, bregma, lambda, basion and pterion give a good superposition of skulls. It will be noticed that if this method is pur- sued the arbitrary element in composite draw- ings or photographs may be eliminated. Franz Boas. XUALA AND GUAXULE. Tue location of two Indian villages, Xuala and Guaxule, mentioned in some form by all of the chronicles of Hernando de Soto’s wild and unfortunate expedition (1539-41) through SCIENCE. 863 the territory now included in the southern states, are important in determining the route of this Spanish adventurer. If the location of these two villages—especially the first— can be determined with reasonable certainty it will enable us to fix the route of the Ade- lantado with comparative accuracy from his landing place at Tampa Bay, Florida, until he reached the vicinity of Mauvilla in Ala- bama. The widest variation in opinion of the nu- merous authorities touching upon the subject, relates to the position of Xuala; these views, however, may be classed in two unequal groups, as is evident from the following list: The map of Cornelius Wytfliet in his ‘ De- serip. Ptolemaica (1596)’ locates this village on the west side of Savannah River near the head. DeLisle’s map (1707?) in French’s ‘Hist. Coll. La.,’ though indefinite, places it west of the Savannah. Later authorities lo- eate it as follows: Pickett (‘ Hist. Alabama,’ I., p. 8); C. C. Jones, Jr. (‘Hernando de Soto, p. 18); Cyrus Thomas (5th ‘ Ann. Rep. Bur. Eth., p. 95); and Theodora Irving (‘ Hist. Cong. Florida,’ IT., p. 8), all locate it west of the upper Savannah in Nacooche valley, Ha- bersham County, Georgia, or in that imme- diate vicinity. Mr. James Mooney (19th “Ann. Rep. Bur. Eth., pt. 1, p. 195) and Wood- bury Lowery (‘ Spanish Settlements within the United States,’ p. 230, in the text, but not on the map) locate it in the ‘piedmont’ region of North Carolina, about the head of Broad river—which would be about Henderson County. Gilmore Shea in his article entitled ‘Ancient Florida,’ in Justin Winsor’s ‘ Narra- tive and Critical History of America, II.,’ follows, in this part of De Soto’s route, the course given by C. C. Jones, Jr. Bucking- ham Smith on the map in his ‘ Narrative of De Soto’ (Bradford Club Series, V., pl. 5) places Xuala about Habersham County, Georgia, but locates Guaxule to the north- west, apparently about Towns County of the same state, or possibly over the line, in Ten- nessee. Although Shipp (‘De Soto and Florida’) does not locate Xuala, he places Guaxule in Bartow County, Georgia, thus agreeing substantially with Pickett, Jones and 864 Thomas. The ‘New International Encyclo- pedia’ follows, in part, Mooney and Lowery, but also differs from them in part. It will be seen from this list that the gen- eral consensus of authorities—all, in fact, but two or three—locate Xuala somewhere in northern Georgia, most of them in Habersham County, while Mooney and Lowery place it in southwestern North Carolina, somewhere in the region of Henderson or Rutherford County. Although the article ‘De Soto,’ in the ‘New International Encyclopedia’ apparently fol- lows Mooney in locating Xuala, though it does not mention the name, it differs radically from them in regard to the immediately following portion of the route, carrying it down the Coosa, instead of the Chattahoochee. It is rather strange that Lowery on the ‘Sketch Map’ of his work locates Xuala in or near Habersham County, northeastern Georgia, and Guaxule about Bartow County, and follows down the Coosa River instead of the Chatta- hoochee as in his text (p. 230). The object at present is to examine briefly the data and determine, if possible, which of these two divergent views agrees most nearly with the original chronicles of the expedition, and the topography of the country, or whether both are erroneous. All the facts bearing upon this particular inquiry to be drawn from the original chron- icles relate to the march from Cofitachiqui— where the Adelantado was so royally enter- tained by the noted cacica—to Chiaha, where he paused to recuperate because of abundant food and pasture. It is now generally conceded that Cofitachi- qui was located on the east bank of Savannah River, at or near Silver Bluff, about twenty- five miles below Augusta, though one or two authors have contended that it was at the junction of Broad and Savannah Rivers. We shall, therefore, proceed upon the assumption that it was at or in the vicinity of Silver Bluff —as this theory is maintained by the views we propose to discuss; calling attention first to that theory which places Kuala in western North Carolina. From Cofitachiqui, according to all the original chronicles, De Soto and his army pro- SCIENCE. [N.S. Vou. XXI. No. 544. ceeded northward, without, so far as the rec- ords show, recrossing the river, hence on the east side of the Savannah, in what is now South Carolina. However, in order to pro- cure a supply of food the army was divided into two parties, that with De Soto going directly onward, while the other turned aside, some twelve leagues, say the chronicles (prob- ably toward the bottom land), where there was a store of maize offered them by the cacica. Before reaching Xuala they passed through some small yillages or settlements of the Chalaque (or Achalaque) now recognized as the Cherokees. The time given for the march from Cofitachiqui to the Chalaque by the dif- ferent chroniclers differs considerably; Elvas states it was seven.days; Garcilasso, eight; and Ranjel (in Oviedo), only two. Biedma does not mention Chalaque, but makes the time occupied in going from Cofitachiqui to Xuala eight days. As further data regarding the time occupied, it may be stated that Elvas makes the time from Cofitachiqui to Xuala twelve days. Ranjel makes it seven days, mentioning as an intermediate village Gua- - quili—not noted by the others—which he says was three days’ march from Xuala. Garcil- asso makes the distance between the same points fifty leagues. All agree in giving the time from Xuala to Guaxule as five days. As the particular view we are now discuss- ing is that maintained by Mr. Mooney and Mr. Lowery (in his text) and the latter fol- lows the former without going into details, for these we have necessarily to refer to the statements by the former. According to these the Chalaque villages were probably on or near Keowee River, for which point we may assume Anderson, An- derson County, South Carolina, as among the modern names along the supposed route. From this point the Adelantado’s force pro- ceeded to Xuala, which this authority, as al- ready stated, places about Henderson County, North Carolina. From there, according to both authorities, they moved west, ‘down French Broad’ River as far, we are justified in supposing (as no point is mentioned), as to or near the site of Asheville. From there these authors carry them southwest to “¥ JUNE 2, 1905.] White County, Georgia, where they arrive at Guaxule. as this theory supposes, was according to the geologist of the U. S. Geological Survey, who has been at work in that section, most likely, as follows: Using modern names to designate the points; from Anderson, South Carolina, to Greenville, same state, 26 miles; thence across Blue Ridge to Hendersonville, North Caro- lina, 85 miles; thence down French Broad valley to Asheville, 22 miles; thence through Hominy Gap and up Richland Creek to Waynesville, 30 miles; thence through Balsam Gap and down Scott’s Creek to Webster, 24 miles; thence across Tuckasugee River and Cowee Mountains to Franklin, 17 miles; thence across Nantahala River and down Shooting Creek to Hiwassee, 32 miles; thence up Hiwassee River and down the Chatta- hoochee to Nacoochee, White County, Georgia, 25 miles, part of this line being along an old Indian trail. As the distance from Silver Bluff to Anderson is about one hundred miles, two or three more or less, this makes the entire distance along this supposed route from Co- fitachiqui to Guaxule three hundred and eleven miles, and from Cofitachiqui to Xuala, one hundred and sixty-one miles, and from Xuala to Guaxule one hundred and fifty miles. Though the route actually traveled accord- ing to this theory may not have been precisely that laid down, it must have been near to and parallel with it, and the distance and character of the country were substantially the same. Our reasons for rejecting this theory are as follows: First, the distance, at least between some of the points, is too great to have been traveled by the army with its incumbrances, among which was a drove of hogs, in the time specified. These hogs may by constantly moving have become good travelers, and may have accomplished the trip from Cofitachiqui to Xuala, a distance of about one hundred and sixty miles} in twelve days—the longest time given by any of the chroniclers. But when the distance from Xuala to Guaxule, which on this route was at least one hundred and fifty miles, has to be traveled in five days, the time given by all the chronicles—a rate of thirty miles per day—the requirement becomes SCIENCE. This route, if traveled by De Soto ~ 865 an utter impossibility for an army thus ham- pered, and scarcely possible for an army free from these incumbrances, especially through a rough and densely wooded country where there were no other roads than narrow path- ways. This route places Xuala on the west or north of the Blue Ridge which has to be crossed in going from Greenville to Hender- sonville. Another insuperable objection to this route is that it requires us to assume that the ter- ritory of the cacica extended into western North Carolina, or included a detached sec- tion therein with the Sara or Cheraw, a Siouan tribe, as subjects, hedged in between the Cherokees and the Catawbas. This would be extraordinary. This assumption is absolutely necessary, if we follow the theory in question, as it is clear, from all the chronicles, that Xuala was under the cacica’s control. It is even stated by one chronicler that after she made her escape, which occurred between Xuala and Guaxule, it was ascertained that she was at the former village where she and the negro Robles, who escaped at the same time, were living as hus- band and wife. The assumption of this route requires not only the supposition that the Cheraws were her subjects and their country in her kingdom, but also when she escaped she went back northward into western North Carolina instead of continuing southward to her own proper capital. It also necessitates the supposition that her flight was mostly through Cherokee country, where she would more likely have been taken captive and pos- sibly slain than kindly concealed and helped on her way. Another reason for rejecting this theory is that it places Guaxule in White County, Georgia, where no mound of the character de- scribed is known to exist or to have existed. It is claimed by advocates of the theory that there is a mound which will answer the de- seription near Clarksville. This, however, is a mistake. There is, it is true, a mound in that locality, but it will by no means fill the requirements. It is in the- upper part of Nacoochee valley, near its western extremity, 866 and it is only about, or a little over, twenty feet high, elliptical in form and flat on top. Its base diameters are 190 and 150 feet and its top diameters 90 and 60 feet. There are no evidences of terraces or a graded way; the sides slope gradually from the summit. It has been plowed over for many years, but this would not have effaced entirely a terrace or graded way had there been one. Moreover, there were no such indications extant half a century ago. There is, however, a mound in Bartow County, Georgia, which does fully meet the requirements of the chroniclers’ descriptions. Another reason for rejecting this route is that it follows down the Chattahoochee River instead of the Coosa; in other words, elim- inates the ‘Coza’ for which the Adelantado was in search, and which his successors en- deayored to reach. Hamlet is taken out of the play unless the name ‘ Coza’ is transferred to Chattahoochee. Another reason for considering this theory erroneous is that although the army must have passed through Cherokee territory after leaving Xuala, if this route was followed, no mention whatever of this fact is made by any of the chronicles. Finally the theory is erroneous because it is based on a mistake. It is apparent, from the statement of the author we have been re- ferring to, that the conclusion reached by others, that Xuala was in northeastern Georgia, was set aside because he had ascer- tained, as he believed, that there was formerly a tribe of Indians named Suali or Suala in western North Carolina; hence as Xuala might be pronounced Shuala, the two must be one and the same people, in fact he says (Nine- teenth Annual Rep. Bureau of Eth., Pt. 195): “As the province of Chalaque is the country of the Cherokee, so the province of Xuala is the country of the Suali or Sara Indians, better known as the Cheraws.” On this slender foundation of a slight re- semblance in names does the theory appear to be built, which takes De Soto and his army, with their hogs and other incumbrances, into the ‘piedmont region of North Carolina.’ The objection, however, does not stop here, for the statement that there was an Indian SCIENCE. [N.S. Von. XXI. No. 544. tribe in southwestern North Carolina known as Suali or Suala appears to be based solely on the name as used by John Lederer in his ‘Discoveries in Three Several Marches’ (1672). But it has been shown (American Anthropologist, N. S., Vol. 5, No. 4, 1903) that his reputed expedition into Carolina is clearly a fiction, that he was never nearer this point than along the southern border of Vir- ginia, his statements in regard to this section are, therefore, unreliable. What few facts he mentions being obtained, in all probability, from the Indians along Roanoke River, and from the accounts of other earlier explorers, with which he seems to have been familiar. His name Suali or Suala seems to refer to De Soto’s Xuala, of which he appears to have obtained knowledge; in fact, he states that it was obtained from the Spanish. As he knew it was somewhere in the direction of his im- aginary journey without any knowledge as to distance, he uses the name to give weight to his fictitious narrative. Distance would have troubled a writer but little who definitely placed a great lake in western North Carolina and believed that the Pacific laved the western slope of the Alleghanies. Unfortunately, however, for the theory, Lederer nowhere applies the name to the In- dians, but throughout expressly limits it to mountains, giving the name Sara to the In- dians. “ The theory, therefore, as given is abso- lutely without a foundation stone, as the name Suali or Suala was never applied to Indians so far as we are able to ascertain until Mr. Mooney so used it in his ‘Siouan Tribes of the East.’ Believing the foregoing reasons to be en- tirely sufficient for rejecting the theory that Xuala was in the ‘piedmont region of North Carolina,’ we next proceed to give our reasons for believing that this village or province was located in northeastern Georgia, and Guaxule in northwestern Georgia, most likely in Bar- tow County. In attempting to trace that portion of De Soto’s route now under discussion it is best to accept what seems to be the most satisfac- tory evidence in regard to one particular lo- cality mentioned. One item is given by Gar- June 2, 1905.] cilasso in respect to Guaxule that appears to fix this town, beyond any reasonable doubt, at the mound group near Cartersville, Bartow County, Georgia. The statement of this au- thor is as follows: “ La casa estava en un cerro alto, como de otras semejantes hemas dicho. Tenio toda ella el derredor un paseadero que podian pasearse por el seis hombres juntos.” “The house [of the chief] stood on a high hill {mound] similar to others we have already mentioned. It had round about it a roadway on which six men might march abreast.” The ‘similar to others we have already men- tioned’ is evidently intended to signify it was artificial, and this is admitted by all who allude to it. The statement that it was ‘high’ signifies more, in the eyes of the Spaniards, than an ordinary elevation. The large mound of the Etowah group near Cartersville, Bar- tow County, Georgia, is 66 feet high with base diameters of 380 and 830 feet, and top diam- eters about 160 and 180 feet. Running up the south side is a broad roadway varying in width from 37 to 56 feet. In bulk it is next in size to the great Cahokia mound near St. Louis. Here then we have a mound which will completely satisfy the description, and the only one in all that section of the south—as is now positively known—which will do so. Moreover, it is sufficiently near Canasauga River to agree with the narrative. There is no reason, therefore, except to maintain a theory, why this should not be accepted as the site of Guaxule. Assuming this as one fixed point, the possibilities of the position of Xuala become much more limited than without this determination. As the suggestion above mentioned, that the Chalaque villages were near the Keowee River, may be accepted as probably correct, it is ap- parent from the limited time of the march from Xuala to Guaxule—five days—that we must place the former town somewhere in northeastern Georgia, probably in White or Hall County or in that section.

A REGULAR meeting was held on April 11, at the American Museum of Natural History, President Rusby in the chair and twenty-two additional members present. The paper of the evening was on ‘Some Edible Seaweeds, by Professor H. M. Rich- After reference to the indirect importance of plankton organisms as a source of food for -animal life in the sea the speaker referred to - those forms of alge which are used directly by man as foodstuffs. They were grouped roughly under four heads—blue-green, grass- green, brown and red alge. In the first group, specimens of a form much prized by the Chinese were shown, which is, according to good authority, Nostoc com- mune flagelliforme. This becomes highly gelatinous when soaked in warm water and is used as a thickening or sauce. A Japanese form, ‘ Su-zen-ji-nori,’ of more doubtful na- ture, but probably an Aphanothece, was also shown. Among the grass-green forms mention was made of xarious species of Ulva and Entero- morpha, which in dried form go under the mame of ‘laver’ in the British isles and -€ao-nori’ among the Japanese. Among the brown forms only one of the Fucacez was mentioned as an article of food, namely Durvillea utilis, which is said to be eaten by the natives in certain parts of Chili. The Laminaria forms, however, include a large number of edible species. Alaria escu- lenta, common both here and in Europe, was at one time eaten occasionally in the occident. At the present time the Japanese and Chinese make great use of these forms, indeed, after fish, they constitute the chief article of export of the Hokkaido. They are exceedingly plentiful in that region and their collection and preparation for market is a thriving busi- ness. In this connection the report of Pro- fessor Miyabe and others was passed around and attention was called to the illustrations showing the mode of harvesting the seaweeds. The two most important species seem to be Laminaria saccharina (Laminaria japonica) and Ulopteryx pinnatifida (presumably iden- SCIENCE. 895 tical with Undaria distans more recently sepa- rated by Miyabe and Okamura), which are known under the respective names of ‘Kombu’ and ‘ Wakame’ by the Japanese. Many other forms are eaten, however. After reference to the well-known examples ‘Trish moss’ (Chondrus crispus) and ‘ dulse,’ it was said that the two types most used are the delicate Porphyra forms and the more massive cartilaginous kinds, such as various Gigartina, Gelidium, Gloiopeltis species. Por- phyra has also been eaten by Europeans and is said to be used by the natives in paris of Alaska, but it is most highly prized by the Japanese and Chinese. Under the name oi ‘asakusa-nori’ it is put up in neat tin boxes and largely sold in the Tokio markets, it being used by itself or for thickening, giving, as it does, a very glutinous mixture with hot waiter. ‘Fu-nori,’ used chiefly as we use starch, is a mixture of species of Gloiopeltis and Endo- trichia, and, like all these forms, is sold dried. The speaker referred to agar-agar, which, on Wiesner’s authority, is said to come irom different species in different regions. That of Ceylon is from Gracilaria lichenoides, that of Java from Eucheuma spinosum, while the Japanese variety is furnished by Gelidium corneum and cartilagineum and Gloiopeltis tenax. Agar, in addition to its uses as a culture medium in bacteriological research, is said to be employed sometimes as an adulter- ant in the jellies of commerce, where it may be recognized by the siliceous frustules of diatoms, ete., from which it is never free. Other forms of Floridee are used as food- stuffs, attention being called to their figures in a Japanese popular work on the useful plants of Japan. In regard to the food value of alg it ap- pears that many of them, especially the blue- green forms, contain a very high percentage of proteids, though not much else of value. The gelatinifying substances obtained from the red forms appears to be a substance called gelose, which is similar to, or identical with, the pectic substances so commonly found either deposited in the middle lamella of the cells of higher plants, or in the walls them- selves. Mention was incidentally made of the 896 SCIENCE. use of seaweeds in the manufacture of iodine and soda-ash. Dr. Rusby exhibited specimens of Fucus vesiculosus and an unnamed form, which are used medicinally. Dr. Howe spoke of dulse as an article of food and of its occurrence in the markets of New York. After further discussion, adjournment fol- lowed. L. H. Lightnin, Secretary pro tem. THE AMERICAN MATHEMATICAL SOCIETY. A REGULAR meeting of the society was held at Columbia University on Saturday, April 29. On the preceding Saturday the Chicago section met at the University of Chicago.

To THE Eprror or Science: At a time when zoologists are making their plans for summer vacation work it seems opportune to direct attention to the advantages offered even in such a distant territory as the Hawaiian Islands. During a visit to the islands last year, under the auspices of the Carnegie Insti- tution, for the purpose of studying the living corals, I was afforded the privileges of the public aquarium recently established near Honolulu, and the directors of the institution desire it to be known that they will be pre- pared to accord a similar courtesy to other zoologists visiting the islands for purposes of research. The aquarium is a modest structure, erected a little over a year ago, and is under the con- trol of the Rapid Transit Company, though the funds were largely provided by the gen- erosity of different gentlemen interested in the welfare of the islands. It is most ad- vantageously situated at Waikiki Beach, a suburb of Honolulu, and the adjacent coral. flats constitute most favorable collecting ground. Though no special appliances beyond exhibition and experimental tanks are avyail- able, yet the advantages of these and a con- stant supply of sea-water appeal to any stu- dent desirous of carrying out investigations on living forms. Moreover, with a generosity which is very praiseworthy, the directors are prepared to make whatever reasonable adapta- tions may be required. Our knowledge of the marine fauna of the Hawaiian Islands is becoming rapidly extend- . ed, mainly through the reports on the collec- tions made by the U. S. Fishery Bureau, under the direction of President D. S. Jordan, during the two successive seasons, 1901 and 1902. The large addition to the number of species of fishes alone shows how very de- sirable was such faunistic work, and other groups are yielding a corresponding number of new forms. The physical conditions of the coral reefs have been studied in part by Professor A. Agassiz. Though the luxuriance of the life on the reefs does not equal that in \ SCIENCE. 897 the more distant Tahiti, Samoa, or the Philip- pine Islands, yet there is sufficient, particu- larly in such places as Kaneohe Bay, to satisfy the most ardent investigator. For the student of terrestrial forms the islands are particularly interesting on account of the influence of introduced animals and plants upon an indigenous fauna and flora. Representatives from the east and from the west, from temperate and from tropical re- gions, here flourish, and against the pests a strong corps of entomologists is engaged in further introduction of possible remedial forms. The fact that the land shells of the islands served to supply the Rev. J. T. Gulick with material for the theory of isolation adds an interest to the evolutionary biologist. The ethnology and various departments of natural history are well cared for by Professor T. H. Brigham, of the Bishop Museum, and his staff of assistants. As a last word of attraction regarding the situation of the aquarium one may quote from the ‘ Report on Collections of Fishes made in the Hawaiian Islands’ by Professor O. P. Jenkins: Of all situations about the island of Oahu, the submerged reef which extends from the entrance of the harbor of Honolulu to some distance past Waikiki furnishes the most prolific supply of fishes, both as to number of species and amount of the catch. This reef at low water is from a few inches to a few feet under water and ex- tends from one mile to two or three miles from the shore, where the water abruptly reaches great depths. Over the surface and along the bluff of this reef may be found representatives-of most of the shore fauna of the Hawaiian Islands. This reef, so favorably situated, so accessible, and so rich in material, can not fail to be of increasing interest to naturalists who may have the good fortune to devote themselves to the study of its wonderful life.

Hill, John Seward, Frank H. 898 Fayant and E. O. Hovey has finished its first exploration of the northern part of the Western Sierra Madre Mountains of Mexico. A sum- mary account of the first half of the trip, from El Paso to Guaynopita, has been given to the readers of Science. The second half of the journey was no less interesting than the first and was fully as productive of scientific ob- servations. Leaving Guaynopita by pack train on March 11, the first stage of the journey was the climb of 3,500 feet out of the Yaqui (Aros) canon in which Guaynopita is located on to the great mesa out of which the mountains of the region have for the greater part been carved. The contrast in vegetation between different parts of this section may be illustrated by the state- ment that fan-leaf palms flourish in the gorges near the river, while on the high mesa one finds the great long-leaf sugar pine predom- inant. Our course lay southward for sixty or seventy miles along the broad plains and nar- row divides forming the mesa, or connecting different parts of it, and we had abundant opportunity of studying the topography of the great Tutuaca Cafion, which is tributary to the Yaqui (Aros), and of observing the contest for the drainage of the plateau between the streams flowing to the west and those flowing to the east. The dissection of the plateau is more pronounced toward the west, and our cross-section of the cafion of the Tutuaca River from its eastern boundary at the edge of the Mesa Venado disclosed acid and basic lavas, tuffs, agglomerates and conglomerates through six thousand feet of beds. The west- ern rim of the Tutuaca Cafion is near the important Dolores mineral district. Some of the extensive igneous action has been accom- panied and followed by strong mineralization of veins. At Dolores a fifteen-stamp mill of the most up-to-date construction is just being completed under the supervision of Manager J. Gordon Hardy for the treatment of the rich gold and silver ores of the Alma Maria vein by the direct cyanide process. Near Dolores we turned southward again and pursued our course along a series ot high SCIENCE. [N.S. Von. XXI.

In this part of our route we passed through three or four fertile ranches and at Yepachie found the people (Tarahumares and Pimas) living for the most part from the tillage of a small alluvial plain surrounded by low mountains. Here we turned westward again and within a few miles reached the Cerro Boludo (Bald Mountain) district, which, like several others on our route, is character- ized by a mineralized quartz vein twenty to eighty feet wide which can be seen traversing hill and vale for miles. Six or eight miles south of Cerro Boludo lies the little Mexican camp of San Francisco, where a diminutive two-stamp mill feeds a primitive arrastra as a preliminary to pan amalgamation of the gold. Thence the Ocampo trail leads over a divide and across the deep cafion of the Rio de Mayo, down into and out of the Rosario arroyo before the great arroyo is reached in the bottom of which, at the Junction of two branch arroyos, is crowded the mining camp of Ocampo—a place better known by its old name of Jesus Maria. This is the site of many rich gold and silver mines, the most famous of which is the Santa Juliana. From Ocampo to Mifiaca, 100 miles, the trail crosses the high mesa, which has a gentle slope eastward and is partly dissected by compara- tively shallow cafions of varying depths. Mifiaca, the present terminus of the Chihua- hua and Pacific Railway, is in a beautiful broad basin about 7,000 feet above tide, which is traversed by the headwaters of the Rio Verde, a tributary of the Yaqui (Aros) River. At Mifiaca our party took train for Chihua- hua and thence went by rail to El Paso, com- pleting our noteworthy circuit in the western Sierra Madre Mountains of northwestern Mexico. The circuit was not very long, com- pared with the mileage of some expeditions, but the results along lines of physiographie, dynamic and economic geology are of impor- tance and will be published as soon as they can be put into proper shape, while the photo- eraphs taken illustrate as completely as prac- JUNE 9, 1905.] ticable the phenomena observed. Among others the problems of buried mountains, bolsen deserts, ’mesas and the structure of the western Sierra Madres have had much new light thrown upon them, if they have not been solved.

To THE Eprror or Science: In the interest of the dignity of scientific research I wish to repeat the statement, made by me on a former occasion, that I have not authorized the sen- sational reports concerning any work; and that I am in no way responsible for the idio- synerasies of our daily press. JACQUES Logs. BERKELEY, May 27, 1905. A BIOGRAPHICAL DIRECTORY OF AMERICAN MEN OF SCIENCE. THE undersigned is compiling a ‘ Biograph- ical Directory of American Men of Science.’ It was begun as a manuscript reference list for the Carnegie Institution of Washington, but arrangements have now been made for its publication. The book should be ready in the autumn, nearly 4,000 biographical sketches being in type. The proofs have been corrected by those concerned, but in order to secure as great accuracy as possible a revised proof will be sent in the early autumn. This letter is written with a view to secur- ing biographical sketches from those living in North America who have carried on research work in the natural or exact sciences but who have not received proof of a sketch for cor- rection. Some of those who were asked to send the information required did not reply even in answer to a second and third request, and there are, of course, many who should be ineluded in the work but who for one reason or another did not receive the request for information. It is intended that each biographical sketch shall contain information, as follows: 1. The full name with title and mail address, the part of the name ordinarily omitted in corre- spondence being in parentheses. 2. The department of investigation given in italics. SCIENCE. 899 3. The place and date of birth. 4, Education and degrees with dates. 5. Positions with dates, the present position be- ing given in italics. 6. Temporary and minor positions. 7. Honorary degrees and other scientific honors. 8. Membership in scientific and learned socie- ties. 9. Chief subjects of research, those accomplished being separated by a dash from those in progress. The undersigned will be under great obli- gations to those men of science who will send him biographical sketches of themselves or who will secure sketches from those who should be included in the work—those who live in the United States, Canada, Newfound- land, Mexico or Cuba, and who have con- tributed to the advancement of one of the following sciences: mathematics, astronomy, physics, chemistry, geology, botany, zoology, pathology, physiology, anatomy, anthropology, psychology. The compiler of the book hopes that any assistance given him to make it as complete and accurate as possible will be at the same time a contribution to the organization of science in America. J. McKeen Carte.u. GARRISON-ON-Hupson, N. Y. SPECIAL ARTICLES. THE NOMENCLATURE OF TYPES IN NATURAL HISTORY. PracticaL work in the arrangement and eataloguing of ‘types’ and other museum material has shown us that the present nomen- clature is not yet sufficient for critically dis- tinguishing all the different classes of such specimens. Further, some of the terms which have been proposed for the purpose are al- ready employed in other ways: for instance, homotype is in use in biology; monotype is the name of a printing machine; autotype is the term for a printing process. We wish, therefore, to submit the following system of nomenclature; and we hope that, in making it more complete, we have provided a scheme which will render efficient service in the labeling and registration of types and typical material. 900 The terms printed in broad-faced letters are the additions or modifications for which we are at present responsible. A fuller explana- tion of all the terms will be found in the ‘Catalogue of the Type and Figured Speci- mens of Invertebrate Fossils in the U. S. National Museum,’ a work which has been prepared by Charles Schuchert and is now passing through the press; and the present article gives a synopsis of the terms which it has been found necessary to use in connection with that and similar work. We now make another suggestion. After the different terms we have placed, in brackets, the contractions which we propose should be used in the actual marking of small specimens to which it is impossible or inadvisable to affix the full label. Our plan for such con- tractions is this: For types of the first class, two capital letters; for those of the second class, one capital and one small letter; for typical specimens, two small letters. s In the definitions which follow, the term ‘ deseription’ indicates either a description by words, or by a picture, or by both combined. For the sake of accuracy we suggest that the original description by words (type-descrip- tion) be called the protolog, the original description by a picture (type-figure), the protograph. It is obviously more easy to identify actual types from the latter than from the former. Primary types Proterotypes. Material upon which original descriptions of species are based. Holotype [H. T.]. The only specimen pos- sessed by the nomenclator at the time; the one specimen definitely selected or indicated by the nomenclator as the type; the one specimen which is the basis for a given or cited proto- graph. Cotype (more properly Syntype) [S. T.]. A specimen of the original series, when there is no holotype. Paratype [P. T.]. A specimen of the origi- nal series, when there is a holotype. Lectotype [L. T.]. A cotype chosen, subsequently to the original description, to take the place which in other cases a holotype occupies (Aeztdés, chosen, picked). SCIENCE. [N.S. Von. XXI. No. 545. Supplementary types (Apotypes vice Hypotype in use). Material upon which sup- plementary descriptions of species are based. Heautotype (vice Autotype in use) [H. t.]. Any specimen identified with an already described and named species, selected by the nomenclator himself in illustration of his species, such specimen not being identifi- able as one of the proterotypes. Plesiotype [P. t.] Any specimen iden- tified with an already described and named species, but not selected by the nomenclator himself, Neotype [N. t.]. A specimen identified with an already described and named species, selected to be the standard of reference in cases when the proterotypes are lost, destroyed or too imperfect for determination, such speci- men being from the same locality and horizon as the holotype or lectotype of the original species. Typical specimens (Icotypes) (2:zés, what is like).* Material which has not been used in literature, but serves a purpose in identifica- tion. Topotype [t. t.]. A specimen of a named species from the locality of the holotype or lectotype, in paleontology from the same local- ity and horizon. Metatype [m. t.]. A topotype identified by the nomenclator himself. Idiotype [i. t.]. A specimen identified by the nomenclator himself, but not a topotype. Homoeotype (vice Homotype, preoccu- pied) [h. t.]. A specimen identified by a specialist after comparison with the holotype or lectotype (dors, resembling). Chirotype [x. t.]. A specimen upon which a chironym is based (chironym, a Ms. name, Coues, 1884). In addition to the above, we have the use of the word ‘type’ in connection with genera—a given species is the type of the genus. The classification of such types is as follows: TYPES OF GENERA (Genotypes). Genoholotype. The one species on which a genus is founded; or a series of species on * éixdc, gen. étKdtoc, evko for evkoto, to make. Ico type for euphony. JUNE 9, 1905.] which a genus is founded, the one species stated by the author to be the ‘ type.’ Genosyntype. One of a series of species upon which a genus is founded, no one species being the genoholotype. Genolectotype. The one species sub- sequently selected out of genosyntypes to become the ‘ type.’ CHARLES SCHUCHERT, S. S. Buckman. ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE. SUMMER MEETING OF SECTION E. Section E of the American Association for the Advancement of Science will hold a sum- mer meeting at Syracuse, N. Y., July 19-22. Arrangements have been made for making the meeting enjoyable and profitable to all mem- bers of the section. The vicinity of Syracuse is one of great interest in several branches of geology: the fossiliferous rocks of the New York series are well exposed in many ravines; the surface shows most of the phenomena of chief interest in glacial geology; the pre- glacial and the modern topography have been worked out by specialists, and the economic geology of the district is important. The chief study in the field during the meeting will be the gorges and lakes of the glacial drainage, which are the most novel features of the dis- trict. In making its plans for the meeting the sectional committee has accepted the cordial invitation of the committee having in charge the joint summer courses in geology for several eastern universities and colleges to hold a meeting in conjunction with the summer school. The following program may now be pro- visionally announced: Wednesday, July 19, 8.00 p.m—The section will meet informally for the purpose of organ- ization and of listening to short addresses by the officers of the section, the state geologist and others. Professor T. C. Hopkins, of Syra- cuse University, will discuss local geology. Thursday, July 20.—F¥ield day with picnic lunch. The section will visit the Jamesville Lakes, the ‘fossil cataracts’ and the several glacial stream channels in the vicinity of THE AMERICAN SCIENCE. 901 Jamesville and part of the shore line of Lake Iroquois in Onondaga Valley. Field addresses will be given by Professor H. L. Fairchild on ‘The Local Glacial Features’ and by Professor John M. Clarke on ‘The New York Series, with Special Reference to the Paleontology and Stratigraphy of the Syracuse district.’ 8.00 p.m.—Popular illustrated lecture by Professor H. L. Fairchild on ‘Glaciation in North America with Particular Reference to the Effects of the Ice Sheet in Central New York.’ 9.30 p.m.—Social meeting in the rooms of the University Club. Friday, July 21.—Field day with picnic lunch. The party will go by trolley to Fayette- ville and thence on foot to the glacial channels and lakes south and west of Fayetteville. Field address by Mr. Frank B. Taylor, ‘ The Great Lakes in Their Relation to Local Geology,’ .00 p.mM.—Business meeting of the section for the reading and discussion of papers. Saturday, July 22.—To Fayetteville by trol- ley or by boat on the Erie Canal. Visit the Fayetteville Channel, Round and White Lakes, the Mycene and adjacent channel northeast of Fayetteville, Salina ,Shales, Manlius lime- stone, Helderberg limestone, Oriskany sand- stone and Onondaga limestone outcrops. Field address by Professor A. W. Grabau on ‘ The Physical Characters and History of Some New York Foundations.’ Free discussions of all papers will be invited.

ConsiwerRING the fact that the setting and resetting of diamonds for cutting purposes involves the use of an alloy, consisting of tin 902 and lead, the handling of which has been as- certained to produce injurious effects, 7. e., lead-poisoning, the government of the Nether- lands has decided to open a competition under the following conditions. The government desires a medium for the setting and resetting of diamonds to be cut —which needs not necessarily be an alloy— the use of which can not produce effects detri- mental to the health of those handling the same, or an elaborate project of altering the method now in use, in such a manner that no such injurious effects can be produced. The following requirements have further to be fulfilled: 1.

Tue India correspondent of the Lancet writes: “The plague epidemic continues with unabated virulence. For the week ending April 22 54,602 deaths were recorded, as com- pared with 51,786 for the preceding seven days. The death-roll for 1905 promises to exceed all former records. In 1901 the total deaths from plague were returned at 273,679, in 1902 the number rose to 577,427, in 1903 904 it reached 851,263 and in 1904 it was 1,022,299. From January 1 of the present year up to April 15 the number of fatal cases is reported at 576,366, and it is very doubtful whether these figures tell the whole truth. Of the total of 64,214 seizures with 54,602 deaths during the week ending April 22 the Bombay presidency had 3,497 cases and 2,787 deaths; Madras, 65 cases and 65 deaths; Bengal, 4,993 eases and 4,351 deaths; the United Provinces, 18,249 cases and 16,637 deaths; the Punjab, 33,162 cases and 27,362 deaths; Burma, 183 cases and 175 deaths; the Central Provinces, 223 cases and 175 deaths; Mysore state, 50 cases and 40 deaths; Haidarabad state, 401 cases and 316 deaths; Central India, 117 cases and 84 deaths; Rajputana, 2,924 cases and 2,406 deaths, and Kashmir, 359 cases with 215 deaths. These detailed figures will show how the disease has extended over the country and the heavy mortality of the cases. The mortal- ity is higher this week in the Punjab by 3,420, in the United Provinces by 753, in Rajputana by 200, in Burma by 20, in Kashmir by 28, in Bombay city by 132 and in Caleutta by 130. The only noticeable decrease is in the districts of Bengal, where the epidemic seems to be ' abating. In this area, however, the outbreak occurred earlier in the season. During the present outbreak the anti-plague serum from the Pasteur Institute in Paris has been some- what extensively used for the treatment of cases both in Bombay and Calcutta, and, al- though it is early to form a definite opinion, numerous individual reports would seem to show its value. UNIVERSITY AND EDUCATIONAL NEWS. Mr. Perctvan Lowetu has established a liberally endowed fellowship, to be known as The Lawrence Fellowship, for the Department of Astronomy at Indiana University. By the terms of the endowment the fellow is ap- pointed by the department, but the appoint- ment is subject to the approval of the founder. A Lawrence fellow shall be given an opportun- ity for astronomical research at the Lowell Observatory and to prepare a thesis on some astronomical subject agreeable to the director SCIENCE. [N.S.

A CHAPTER, ALMOST UNIQUE IN THE FASCINATING HISTORY OF LATTER-DAY SCIENTIFIC EXPLORING EXPEDITIONS ANTARCTICA, or Two Years Amongst the Ice of the South Pole By Dr. N. OTTO G. NORDENSKJOLD ana Dr. JOHAN GUNNAR ANDERSSON Dr. Nordenskjéld’s was one of the expeditions planned at the International Geographical Congress of 1895, by which a concerted attack was made upon this enormous unknown tract lying around the South Pole. The part assigned to the Antarctic was to approach the east coast of the frozen southern land early in the autumn of 1901, penetrate as far southward as possible and land a winter- ing party of six under Dr. Nordenskjéld himself. She was then to return to the Falkland Islands and Tierra del Fuego, picking up the party in the following spring. But the next year proved the coldest and hardest yet experienced in point of ice conditions. The Antarctic was unable to reach the wintering-place again. Dr. Andersson with two companions attempted to reach it over the ice. The ship tried to force a way farther to the east. Both attempts failed ; the vessel was nipped by the ice and sank ; and all three parties, isolated from each other, had to spend a second enforced winter in those regions, Altogether the book forms as thrilling a narrative of scientific adventure as can be found—all its adverse fortunes seeming to have but enhanced the value of the scientific and geographical observations obtained by the expedition and made far more perfect by being continued through so long a period.

Columbia University in the Wity of Hem Bork ; Columbia University includes both a college and a university in the strict sense of the words. The college is Colum- oia College, founded in 1754 as King’s College. The university consists of the Faculties of Law, Medicine, Philosophy, Political Science, Pure Science and applied Science. The point of contact between t e college and the university is the senior year of the college, during which year students in the college pursue their studies, with the consent of the college faculty, under one or more of the faculties of the university. Barnard College, a college for women, is financially a separate corporation ; but educationally, is a part of the system of Columbia University. Teachers College, a professional school for teachers, is also, financially, a separate corporation; and also, educa- tionally, a part of the system of Columbia University. Each college and school is under the charge of its own faculty, except that the Schools ot Mines, Chemistry, Engi- neering and Architecture are all under the charge of the Faculty of Applied Science. For the care and advancement of the general interests of the university educational system, as a whole, a Council has been established, which is representative of all the corporations concerned. I.. THE COLLEGE, Columbia College offers a course of four years, leading to the degree of Bachelor of Arts. Candidates for admission to the college must be at least fifteen years of age, and pass an examination on prescribed subjects, the particulars con- cerning which may be found in the annual Circular of Information. Barnard College, founded in 1889, offers for women a course of four years, leading to the degree of Bachelor of Arts. Candidates for admission to the college must be at least fifteen years of age, and pass an examination on pre- seribed subjects, the particulars concerning which may be found in the annual Circular of Information. II. THE UNIVERSITY. In a technical sense, the Faculties of Law, Medicine, Philosophy, Political Science, Pure Science, and Applied Science, taken together constitute the university. These faculties offer advanced courses of study and investigation, respectively, in (a) private or municipal law, (b) medicine, (ce) philosophy, philology and letters, (d) history, economics and public law, (e) mathematics and natural science, and (/) applied science. Courses of study under all of these facul- ties are open to members of the senior class in Columbia College. Certain courses under the non-professional facul- ties are open to women who have taken the first degree. These courses lead, through the Bacheélor’s degree, to the university degrees of Master of Arts and Doctor of Phi- losophy. The degree of Master of Laws is also conferred for advanced work in law done under the Faculties of Law and Political Science together. Ill. THE PROFESSIONAL SCHOOLS. The faculties of Law, Medicine and Applied Science, con- duct respectively the professional schools of Law, Medicine, and Mines, Chemistry, Engineering and Architecture, to which students are admitted as candidates for professional degrees on terms prescribed by the faculties concerned. The faculty of Teachers College conducts professional courses for teachers, that lead to a diploma of the university. 1. The School of Law, established in 1858, offers a course of three years, in the principles and practice of pee and public law, leading to the degree of Bachelor of Laws. 2. The College of Physicians and Surgeons, founded in 1807, offers a course of four years in the principles and practice of medicine and surgery, leading to the degree of Doctor ot Medicine. 3. The School of Mines, founded in 1863, offers courses ot study, each of four years,leading to a professional degree, in mining engineerin and in metallurgy. 4. The Schools of Chemistry, Engineering and Architect- ure, set off from the School of Mines in 1896,offer respect- ively,courses of study,each of four years,leading to an appro- priate professional degree, in analytical and applied chem- istry ; in civil, sanitary, electrical and mechanical engineer- ing; and in architecture. 5. Teachers College, founded in 1888 and chartered in 1889, was included in the University in 1898. It offers the fol- lowing course of study: (a) graduate courses leading to the Master’s and Doctor’s diplomas in the several departments of the College: (b) professional courses, each of two years, leading to the Bachelor’s diploma for Secondary Teaching, Elementary Teaching, Kindergarten, Domestic Art, Domes- tic Science, Fine Arts, Music and Manual Training ; (c) a col- legiate course of two years, which, if followed by a two- year professional course, leads to the degree of Bachelor of Science. Certain of its courses may be taken, without extra charge, by students of the University in partial fulfill- ment of the requirements for the degrees of Bachelor ot Arts, Master of Arts, and Doctor of Philosophy. The price of the University Catalogue is twenty-five cents postpaid.

Al- though for practical purposes it is convenient to mark it out into the primary regions of physics, chemistry and biology, and to subdivide these into subordinate provinces, yet the method of investi- gation and the ultimate object of the physical in- quirer are everywhere the same.”—Huxley. Physical seience is one and indivisible; that, as I understand it, is the key note of this great congress, of which public health science forms one section, and as I am in- vited to eonsider, in the brief space of forty-five minutes, the relations of public health science to other sciences, I shall take the lberty of selecting from the whole number of ‘other sciences’ only a few, the relations of which to public health science seem to me for one reason or another espe- cially important at the present time. I accept the term public health science with- out hesitation, for any division of human knowledge which has worked out its own laws with strict adherence to the rules of inductive and deductive reasoning, as public health science has done, and which has reached results enabling it to predict with accuracy, as public health science can now predict, is entitled to a place and an honorable place among the physical sci- ences. Public health science had its rise and a considerable development in the eighteenth century. Before that time numerous pro- cedures tending to protect or promote the pubhe health had, indeed, at one time or * Address before the International Congress of Arts and Science, St. Louis Exposition. ° 906 another existed, but these were largely em- pirical and quite as often directed to the convenience of mankind as to their sani- tary safety. In this class belong the Mosaic code; the water supply introduced into Jerusalem by Hezekiah; the sanitary engineering of Empedocles; the Cloaca maxima; the water supplies of ancient Mycene and of Rome; and all the earlier, and too often futile, forms of quarantine. Even the art of inoculation for smallpox was only an ingenious knack introduced from the east, where it had been long used empirically, and although it was a public health measure now of the utmost interest and capable at the time of great practical service, it had until recently no scientific basis, but belonged in nearly the same class as the amulets and charms, the pray- ers and incantations, of the superstitious. It was not until the middle of the eight- eenth century, namely, in 1767, that Sir George Baker, by the use of the methods of pure inductive reasoning, made the first scientific discovery in public health science in the subdivision of epidemiology, namely, that the epidemic colic of Devonshire, Eng- land, was due to an obscure poisoning by lead conveyed through the common cider used for drinking in that district. In 1774 the foundations of state hygiene and sanitation were laid in consequence of the patient investigations and startling revela- tions of John Howard, by an act of Parlia- ment providing for the sanitation of jails and prisons. The beginnings of marine hygiene and sanitation appear in 1776, when Captain Cook, the navigator, was awarded the Copley medal of the Royal Society for his remarkable success in pro- tecting the lives of his sailors on his sec- ond voyage. In 1796 Edward Jenner, working also in a strictly scientific man- ner, and employing the methods of rigid inductive research, laid securely for all SCIENCE. [N.S. Von. XXI. No. 546. time the foundations of personal hygiene and immunization, by showing how we can produce at will such modifications of the physiological resistance or susceptibility of the human body as to make it immune to smallpox. The importance of these fundamental and splendid discoveries, not only to the public health of the time, but far more to the development of public health science in all the centuries to come, is inecaleu- lable. Reduced to their lowest terms, we have in these eighteenth century discoveries the germs of some of the most important divisions of public health science as it is to-day, namely, (1) epidemiology, (2) sanitation of the environment, and (3) m- munization of the human mechanism, this last the most marvelous phenomenon hith- erto discovered in personal hygiene. Time fails me to do more than name some of the principal steps in the advance- ment of public health science in the nine- teenth century. We have, for example, in 1802, the beginnings of factory hygiene and sanitation; in 1829, the first municipal water filter, one acre in area, constructed for the Chelsea Company of London; in 1834, recognition of the important relation of poverty to public health, in the famous report of the Poor Law Commissioners of that year; in 1839, the beginnings of reg- istration and accurate vital statistics; in 1842, an important report on the sanitary condition of the laboring population of England; and in 1848, a similar report on the health of towns; in 1854, for the first time clearly taught, the lesson, even yet not properly taken to heart, that drinking water may be the ready vehicle of a ter- rible epidemic of cholera. About 1860, striking epidemics of trichinosis first came into public notice, and here, also, belongs the magnificent work of Pasteur, while in 1868, Lister, following in the footsteps of a JUNE 16, 1905.] Pasteur, revealed to the world the basis of true cleanliness in asepsis, and in 1876, bacteriology became firmly established as a science by Koch’s studies on anthrax. The decade from 1880 to 1890 may be ealled the golden age of ewxtiology, for in these years were discovered the hitherto un- known parasitic microbes of typhoid fever, tuberculosis, malaria, Asiatic cholera, diph- theria and tetanus. The last decade of a century which has well been ealled ‘the wonderful,’ witnessed the discovery of antitoxins by Behring and the beginnings of serum therapy. The list is long, and I have not mentioned nearly all of the dis- coveries of capital importance, but because of these and their fruits, I am in the habit of saying to my students that with the single exception of the changes effected by the acceptance of the theory of organic evolution, there has been no modification of human opinion within the nineteenth cen- tury more wonderful, or more profoundly affecting the general conduct of human life, than that in our attitude toward the nature, the causation and the prevention of disease—that is to say, toward public health science. No mere outline like this of the history of public health science can possibly serve to show how, like other applied sciences, this one has not grown as a branch grows from a tree, namely, from a large stem or stock of knowledge, tapering out into thin air, and with its latest growth its least and weakest. That common simile in which the various divisions of science are repre- sented as branches of the tree of knowl- edge, is a grotesque survival of a time when neither trees nor science were understood. No simile is perfect or even approximately correet, but one better than the tree and its branches for the origin and relation- ships of any inductive science is that of a river, rising from various and often ob- SCIENCE. 907 scure sources, growing in size and impor- tance as it proceeds both from the springs within its own bed and by the entrance and contributions of tributary streams, and finally pouring its substance into the mighty ocean of accumulated human knowledge. Up to the time of the establishment of the registration of vital statistics in Eng- land, in 1839, the stream of public health science, although full of promise, was only a slender thread, but when the results of registration were fully enlisted in its service it visibly widened and deepened. Epidemiology, as has been said, had the honor of giving birth to the science in 1767, and it added to its offspring a rich endowment when, in 1854, Dr. John Snow proved that the water of the Broad Street well in London had caused an epidemic, in which more than six hundred persons died of Asiatic cholera. The stream of public health science was still further en- larged and quickened by the revelation in and after the sixties of the simple causes of numerous epidemics of trichinosis and of typhoid fever, the latter sometimes through milk. There was an extraordi- nary popular awakening in England to the importance of sanitation and public health measures in the middle of the nine- teenth century, but we look for some time in vain for any marked inosculation be- tween public health science and other sci- ences, such as physics, chemistry, micro- scopy, bacteriology, climatology, engineer- ing or education. We have, to be sure, minor contributions from the microscopists, such, for example, as that from Dr. Has- sall, who, in 1850, made a careful micro- scopical examination of the water supply of London and showed the presence in the public drinking water of muscle fibers, intestinal parasites and other materials, plainly derived from sewage; but it was 908 not until Pettenkofer and his disciples, in Germany, and Angus Smith and others, in England, began their splendid chemical in- vestigation that the tributary stream of sanitary chemistry enlarged materially that of public health science. In saying this I do not forget that my late friend and colleague, William Ripley Nichols, whose solid contributions to sanitary chem- istry were among the first in America, and will always remain among the best any- where, long ago pointed out that, as early as 1789, Foureroy studied the nature of ‘litharged’ wine, Berthollet (1801) the methods of preserving water for long voyages, Chevreul (1846) various chemical reactions which explain the hygiene of populous cities, and (1856, 1862, 1870) methods of preparing and preserving food; Graham and Hofmann reported upon the use of acetate of lead in sugar refining (1850), upon the London water supply (1851), and upon the adulteration of pale ales with strychnine (1882); Dumas was inter- ested in many sanitary matters and made, among others, reports on the mineral waters of France (1851), on the water supply of Paris (1859), on the treatment of sewage (1867), and on the pres- ervation of food (1870-72); Wurtz was for a number of years president of the Comité con- sultatif dhygiéne and a year before his death was president of the Société de médecine publique. His investigations and reports on sanitary sub- jects are numerous—on the disposal of the waste from distilleries and sugar-refineries, on the colors employed on German toys and in articles of food, on the adulteration of wines, ete. Other names will oceur to us—such as those of Sir Henry Roscoe, Sir Frederick Abel and Dr. Williamson, who served on the Noxious Vapours Commission of 1876; of Frankland, who gave years of service to the Rivers Pollution Com- mission of 1868 and in connection therewith de- vised an elaborate system of water analysis; we think also of Schutzenberger devising a method for the determination of oxygen dissolved in water (not, to be sure, simply for sanitary pur- poses), Mallet studying the various methods of water analysis, Remsen studying the organic mat- ter in the air, and Leeds the practical effect of charging with oxygen (or rather with air) water used for purposes of domestic supply.* *Wm. Ripley Nichols, address before Ameri- SCIENCE. [N.S. Von. XXI. No. 546. I dwell intentionally upon the service of sanitary chemistry to public health science previous to the rise of bacteriology, because I believe that, dazzled as we have been and still are by the blazing achievements of bacteriology, beginning, let us say, with the discovery of the microbe of tuberculosis by Koch in 1882, students of public health science have been too much inclined to un- derrate the past services and present rela- tive importance of sanitary chemistry. I know of few more important contributions to public health science, even since 1882, than the chemical work of the State Board of Health of Massachusetts under the able direction of my friend, Professor, after- wards President, Drown (the successor of Nichols) and his associates and successors ; or that of another friend, the late Professor Palmer, of the University of Illinois, whose chemical studies of the rivers of Illinois will long remain a monument to a life full of promise and too soon eut short, or that of still another friend, Professor Kinniecutt, who fortunately is still engaged in fruit- ful work. I have perhaps said enough, though it would be difficult to say too much, of the magnificent contributions to public health science of Pettenkofer and his disciples in sanitary chemistry; but the work of these investigators in sanitary physics and espe- cially the physies of the soil, of the atmos- phere, of the walls of buildings, and of heating and ventilation, in their relations to the public health are quite as important, and perhaps to-day even more neglected. In view of the increased facilities for transportation and the growing habit of traveling, together with the tendency to outdoor life, which seem to be character- istic to-day of all civilized nations, the next twenty-five years will probably see a re- can Association for the Advancement of Science, Proceedings American Association for the Ad- vancement of Science, Vol. XXXIV., 1885. | es Se ee oe JUNE 16, 1905.] turn to the patient and exact studies of the environment, such as the chemists and physicists began, and have in some meas- ure continued, since the middle of the nine- teenth century. These studies will be directed largely to further knowledge and - control of the environment, but they will not end there, for personal hygiene, owing to recent advances in physiology, is to-day one of the most inviting fields for work and education, and I hardly need to point out to a company of experts that the proper eare and right use of the individual human mechanism reacts favorably and funda- mentally upon the public health no less truly or effectively than an improved con- dition of the environment or of the public health tends to promote the welfare and long life of the individual. The sphere of hygiene may be divided, as it often is, into the two hemispheres, public hygiene and personal hygiene, or it may be cut into one portion dealing chiefly with the human mechanism and its opera- tion (personal hygiene), and another por- tion dealing chiefly with the environment of that mechanism (sanitation). The time has gone by when any one person can safely undertake to deal with the whole sphere of hygiene. The physiologist and the physician must in the future leave to the architect and the sanitary engineer such subjects as housing, heating and venti- lation, water supply and sewerage, pre- cisely as the sanitary engineer has never presumed to deal with foods and feeding, vaccines and antitoxins, exercise, sleep and rest. The former subjects deal chiefly with the control of the environment, the latter subjects chiefly with the control of the in- dividual, and sanitation and hygiene must henceforward be regarded as_ separate hemispheres of the science of health. The science of architecture, if under this head we inelude the principles of building SCIENCE. 909 construction, and the heating and ventila- tion of buildings, has dorie and is doing much of interest and importance to the student of public health science. For my own part, I am continually more and more impressed with the fact that the air supply, especially for the modern civilized and too often sedentary form of mankind, is in the long run quite as important as the water supply, the milk supply or any other supply. Surely, we ean not be too careful of the purity of a substance which we take into our bodies oftener, and in larger volume, than any other, and which has come, rightly no doubt, and as the result of long and painful experience, to be known as the very breath of life. I am well aware that human beings may sur- vive and seemingly thrive, even for long periods, in bad air, but I am certain that for the best work, the highest efficiency, the greatest happiness and the largest life, as well as for perfect health, the very best atmosphere is none too good. Hence I believe that the permeability of the walls. of houses and other buildings, and the heating and ventilation of dwellings, school houses, churches, halls and other public places, require, and in the near future will receive, a much larger share of our attention than they have to-day. In an age characterized by urban life and possessing sky-scrapers, tenement houses and other huge bee-hives, in which human beings aggregating vast numbers spend a large part of their lives, buildings require for their proper construction, lghting, heating, air supply, water supply, gas sup- ply and drainage, the scientific services not only of architects, but of engineers, and such publie buildings form one small sec- tion of the aid which modern engineering science 18 now everywhere rendering to public health science. The present has rightly been called an ‘age of engineering,’ 910 and to no other science, excepting only medicine itself, is public health science to- day more indebted than to engineering science. I have referred above to the con- struction of the first municipal filter at- tached to a public water supply as that of the Chelsea Company of London, con- structed in 1829. How different is it to- day! Not only nearly the whole of Lon- don, but also Berlin and Hamburg, and a thousand lesser cities all over the civilized world, are now protected more or less per- fectly from epidemics of typhoid fever, Asiatic cholera and other water-borne dis- eases by vast municipal filters, ingenious and scientific in design and costly in con- struction, the work of skillful and faithful engineers, and monuments, more precious, if less enduring, than brass, to the con- tributions of engineering science to public health science. Innumerable storage reser- voirs and vast distribution systems for sup- plies of pure water also bear witness to the enormous debt which public health science owes to engineering science, as do proper street construction and, still more, those splendid systems of sewerage with which so many modern cities are equipped, and which not only serve to remove quickly the dangerous liquid waste of human and ani- mal life, but also keep low and wholesome the level of the ground water, reducing dampness and promoting dryness of the ‘environment, and thereby strengthening that physiological resistance by means of which the human mechanism fights against the attacks of infectious disease. Nor do the services of engineering science end here, for the fluid content of the sewers must always be safely disposed of, and sewage purification is to-day a problem of engi- neering science no less important or diffi- cult than that of water purification. These same processes of the purification of water and sewage are matters of so much moment SCIENCE. [N.S. Von. XXI. No. 546. in public health science that in almost every country experiment stations are now main- tained at public and private expense for the purpose of working out the most prac- tical and most scientific methods of purifi- cation. In no respect have the services of engi- neering science to public health science been more conspicuous than in the applica- tion and the further study of the principles involved in the processes of water purifica- tion. It has lately been shawn, for ex- ample, that the introduction of pure water supplies has in many eases so conspicuously lowered the general death rate as to make it impossible to escape the conclusions (1) that the germs of a greater number of in- fectious diseases than was formerly sup- posed are capable of prolonged life in, and ready conveyance by, public water sup- plies, and (2), as a promising possibility, that as the result of the greater purity of the water supply the physiological resist- — ance of the consumers of pure water sup- plies is enhanced, in some manner as yet unknown; the net result being that the gen- eral death rate is lowered to such an extent as to lead to a rapid increase of population in communities previously stationary or multiplying far less rapidly. In the case of the city of Lawrence, Mass., for example, I have recently had the privilege of exam- ining the results of studies by the dis- tinguished hydraulic and sanitary engi- neer, Mr. Hiram F. Mills, which show that since the introduction of a municipal filter, which purifies the water of the Merrimac River supplying water to the citizens of Lawrence, while the population has in- creased nearly seventy per cent., the total number of deaths remains about the same as it was ten years ago. Mr. Mills con- cludes from the results of his studies—and I see no escape from his conclusions—that the introduction of the municipal filter has JuNE 16, 1905.] not only saved the lives of thousands of citizens, but has also caused the population to increase to a point much beyond any which it would have reached had the city continued to use, unpurified, the sewage- polluted water of the Merrimac River. A demonstration of this sort shows how easily the diminishing increase of population un- der a lower birth rate may sometimes be counteracted without resort to that fish- like spawning which seems to be the only remedy of those who are terrified by ‘race suicide,’ so called. Moreover, it is hardly necessary to point out that such a dimin- ishing death rate means a far more rapidly diminishing morbidity rate—in other words, it means a heightened working efficiency of the population as a whole, and it must not be forgotten that for most of the results obtained in the scientific purification of water supplies we are indebted to the sci- ence of engineering. On the other hand, we must observe that engineering science, so far as water puri- fication is concerned, is as yet only in its infaney. and by no means thus far alto- gether satisfactory. In the United States, for example, in the last two or three years a. number of epidemics of typhoid fever. have resulted from the defective operation or construction of municipal filters, and while much has been done, it is clear that much still remains to do. In this connec- tion it should be said that public health science in the United States suffers con- stantly and severely from an unsatisfac- tory condition of the science and art of administration or government in many American cities. Public health works are too often neglected, delayed, mismanaged or built at extravagant cost, to the sanitary and economic damage of the people as a whole, and the tendency is far too common to place the care and operation of costly devices or systems in incompetent hands. SCIENCE. 911 I can not here dwell, as long as I should like to do, upon the mutual relations of public health science and the sciences of legislation and administration. Speaking of my own country alone, I must confess that we are still very deficient in the appli- cations of these sciences. We have not even a national board of health, although we have, fortunately, in the Public Health and Marine Hospital Service a strong sub- stitute for one. The peculiarities of our democratic and republican government have hitherto made it impossible for the people of the United States to secure either from federal authorities or from more local sources that measure of paternal sani- tary and hygienic protection which they ought to have, and it is the duty of every American worker in this field to bend his energies toward a better organization of the public health service in every direction, municipal and state as well as national. The appointment in 1886 of a distinguished hydraulic engineer to membership on the State Board of Health in Massachusetts marked an epoch, so far as America is con- cerned, in both sanitary legislation and administration. This appointment was a formal recognition on the part of the public of the necessity of a larger proportion of engineering science in matters relating to the public health, and the results have justi- fied the new procedure. It is now, for- tunately becoming less rare in America to secure the services of engineers upon such boards and there can be no question that participation of the expert laity with med- ical men is likely to be extended, probably far beyond our present ideas. In a notable discourse before the Inter- national Medical Congress at the Centen- nial Exposition held at Philadelphia in 1876, Dr. Henry P. Bowditch, of Boston, one of the pioneers of hygiene and sanita- tion in America, divided the century then 912 SCIENCE. closing, as to its relation to public health science, into three periods, the first, from 1776 to 1832, a period of reliance upon authority and upon drugs; the second, from 1832 to 1869, a period of true scien- tifie observation; the third, from 1869 on- wards, an epoch in which the medical pro- fession is aided by the laity and _ state hygiene is inaugurated. Dr. Bowditch has much to say of the desirability of a wider. cooperation of the laity in state hygiene and remarks: ‘In all that tends to the promotion of state hygiene hereafter thé laity will naturally and cordially cooperate with the [medical] profession.’ The his- tory of public health science shows Dr. Bowditch’s prediction to have been well erounded. The names of John Howard and Captain Cook in the eighteenth cen- tury, and of Edwin Chadwick, John Simon and Louis Pasteur (not to mention a host of lesser workers) in the nineteenth cen- tury, show conclusively that public health science has been, even from the start, by no means confined to medical men. We may go further and say that even when forwarded. by medical men these have sel- dom been busy practitioners. Sir George Baker and Jenner were, it is true, of this class, but not Pettenkofer or Koch or Ross or Billings or Reed.* Reflections of this sort naturally lead to a consideration of the reciprocal relations of public health science and the science of education. I do not need to dwell upon the beneficial effects of public health sci- ence upon the hygiene and sanitation of school children or school houses. These benefits have long been emphasized by sani- tarians and sanitary reformers, and are sufficiently obvious. The reverse of the picture, however, is by no means so well * “uring the course of an epidemic physicians are too busy to make observations which require much time or care, or to make more than brief notes.”—J. 8. Billings. [N.S. Vou. XXI. No. 546. understood. Unless one is familiar with the facts, it is difficult to conceive how little impression the splendid progress which the last fifty years have witnessed in public health science has as yet made upon the curriculum of education. From top to bottom and from bettom to top the schools, whether primary, grammar, high, normal, technical, medical or any other class, are recreant, inasmuch as they neglect almost wholly any adequate training of their pu- pils in the principles of public health sci- ence, which are confessedly of such pro- found importance to mankind. There is, to be sure, just now a popular wave of en- thusiasm touching the extermination of tuberculosis, but in the United States, at any rate, both schools and universities are singularly negligent of their most element- ary duties in this direction. Yet if what I have said before is true, if the laity are to participate from this time forward with medical men in sanitary and hygienic legislation and administration, if engineers and medical men in particular are to serve upon boards of health or in other executive positions connected with publie works, then, surely, it is the duty of the science of edu- cation to lend its powerful aid and not to fail to save the lives and health of the people as these can be saved to-day, but always to promote that public health and that large measure of consequent happiness which can probably be more easily and quickly accomplished in this way than in any other. As to the function of medical education and engineering education in respect to the dissemination of public health science, I shall say only a word. In spite of the reiteration by medical men of their belief in the importance of hygiene and pre- ventive medicine as a part of the equip- ment of the medical profession, it is a significant fact that in America even the JUNE 16, 1905.] best medical schools devote very little time to any adequate instruction in these sub- jects. It may be that this is wise and that the pressing necessities of practical medi- cine forbid any extended instruction in public health science. I am willing to be- lieve, if I must, that this may be the ease; but if it is, then the community must look for the most part elsewhere than to medical men for adequate investigation, legislation and administration of public health science. Medical men, must, of course, always par- ticipate in the work, in connection, particu- larly, with the control of epidemics and in those forms of preventive medicine which have to do with vaccines, serums and other means of modifying the vital resistance of the human body. But as regards the care and control of the environment, medical Knowledge is not indispensable, and the entrance of the engineer and the sanitary expert upon the field, as foretold by Dr. Bowditch nearly twenty years ago, is to- day a conspicuous, and probably a whole- some, fact. As to the attitude of engineer- ing education toward public health science there can be no question. If what I have said before is true, then engineers are bound in the future to take constantly a larger and more important part in public health work, and must be informed, and if possible trained, accordingly. Moreover, as regards both medicine and engineering, the problem is by no means insoluble, for a very short course of instruction rightly given would easily ineuleate the necessary fundamental principles, while electives or post-graduate work might enable those few whose tastes led them in this direction to investigate and specialize and more thor- oughly prepare themselves for public serv- ice. I can not treat, nor do I need to treat, as thoroughly as I would be glad to do, the mutual relations existing between medical SCIENCE. 913 science, especially the science of medical bacteriology, and public health science. These are already sufficiently obvious and well known. ical men have served, often devotedly and sometimes heroically, in the cause of public health science. I take it, however, that since we have in this congress and in our own department a section of preventive medicine, I may pass over without com- ment this part of my subject. As regards sanitary bacteriology, how- ever, the relations existing between this and public health science are so funda- mental, so extensive and so important, not only on the medical, but also on the engi- neering side, that although we have also in this congress under the department of biclogy, as is entirely proper, a section of bacteriology, I may linger at this point for one moment. The bacteria and other microscopic forms of plant and animal life, all of which are conveniently included under the term microbes, have so lately begun to be understood and appreciated that we must still emphasize their extreme importance. The discoveries of the botan- ists and zoologists and revelations of the microseopists in this domain are compar- able, in their importance to public health science, with nothing less than the revela- tions of the telescope to astronomy. As- tronomy had, indeed, existed long before the invention of the telescope, and public health science, as we have shown above, had its beginnings nearly a century before any considerable progress had been made in micro-biology. But it is not too much to say that the developments in miero- biology since Pasteur began his work have not only revolutionized our ideas of the nature of the infectious diseases, but have also placed in our hands the key of their complete control. Concerning the relations of physiology From time immemorial med- 914 to publie health science, I must not fail to speak. Here is a field absolutely ripe for the harvest, but one in which the harvesters are as yet very few. I have lately had occasion to examine somewhat carefully the present condition of our knowledge of per- sonal hygiene—which is nothing more (and should be nothing less) than the applica- tions of physiologial science to the conduct of human life—with the result that I have been greatly impressed with its vast possi- bilities and promise. Man is a gregarious animal, and mankind is to-day crowding into cities as perhaps never before. More- over, the industrial and commercial age in which we live is characterized to an ex- traordinary degree by the sedentary life. Yet the sedentary life is almost unavoid- ably an abnormal life, or at least it is a life very different from that lived by most of our ancestors. In the sedentary life the maintenance of a high degree of physiolog- ical resistance apparently becomes difficult, and if the vital resistance of the community in general is lowered then the public health is directly and unfavorably affected, so that considerations of personal hygiene have a direct bearing upon the science of public health. There are, to be sure, interesting and suggestive symptoms of a wholesome reac- tion, in America, at any rate, against the evils of the sedentary life. Parks and open spaces are being liberally provided; puble and private gymnasiums are rapidly coming into being; publie playgrounds are thrown open in many of our cities, free of expense to the laboring, but, nevertheless, often sedentary, population; vacations are more than ever the fashion; sports and games are everywhere receiving increasing attention; while publie baths and other de- vices for the promotion of personal hygiene are more and more coming into being. All this is as it should be, but all is as yet only SCIENCE. [N.S. Vou. XXI. No. 546. a beginning. Here, again, the science of education is sadly at fault and in the direc- tion of educational reform as regards per- sonal hygiene lies immense opportunity for a contribution to public health science. The science of statistics, which has done great service in public health science in the past, is likely to do much more in the future. Without accurate statistics of population, mortality and the causes of sickness and death, the science of epi- demiology is impotent, and the efficiency or inefficiency of public health measures can not be determined. And yet in ignorant hands statistics may be worse than useless. It is a matter for congratu- lation to Americans that we now have in Washington a census bureau permanently established and under expert supervision, but until the various states and cities of the United States follow this excellent ex- ample of their Federal Government, one of the most important aids to public health ° science will continue to be wanting, as is unfortunately too often the case to-day not only in America, but in many other parts of the civilized world. Wiuuiam T. Sep@wick. MASSACHUSETTS INSTITUTE oF TECHNOLOGY. SCIENTIFIC BOOKS. Manual of the Trees of North America (Exclu- sive of Mexico). By CHarLes SPRAGUE Sar- GENT, director of the Arnold Arboretum of Harvard University, author of the Silva of North America; with six hundred and forty- four illustrations from drawings by Charles Edward Faxon. Boston and New York, Houghton Mifflin and Company; Cambridge, The Riverside Press. 1905. Pp. 24+ 826, octavo. A few years ago Professor Sargent brought to a successful close his monumental work, ‘The Silva of North America,’ in fourteen massive quarto volumes, and including de- scriptions and figures of 585 species of trees. ———rerrrrr JUNE 16, 1905.] While this must for centuries be the standard work on our native trees, its bulk and cost preclude its use elsewhere than in the herba- rium, museum or library, and it was impera- tive that the same author should prepare a handy field (or rather, forest) manual which should give to a much larger number of people the opportunity of studying our forest trees. This has now been done in an admirable manner in the Manual which made its ap- pearance some time in March of the present year. The book opens with a synopsis of the sixty- one families of plants included, the sequence being that of Engler and Prantl’s ‘ Die Natiir- lichen Pflanzenfamilien,’ and this is followed by an analytical key to the families, based on the characters of the leaves. Then follows the descriptive manual proper, in which after a clear and pretty full characterization of each family there is given a conspectus or analytical key to the North American genera. The char- acters of each genus are set forth much more fully than they are in the usual botanical manuals, and a paragraph is usually appended giving geographical, numerical and economic data. A convenient key enables the student to readily find the particular species in which he is interested. : The specific descriptions leave nothing to be desired, usually including full descriptions of the leaves, flowers, fruits, seeds, the tree as a whole, its winter buds, bark and wood, and are followed by concise accounts of their natural geographical distribution, and the extent of their cultivation for ornamental and other pur- poses. With each species is a figure of the characteristic features of the species, usually the foliage, flowers and fruit. By means of these figures alone one can identify nearly every species. The book is thus thoroughly satisfactory, and must at once become a standard among systematic manuals. It will appeal to the gen- eral botanist as a distinct and notable contri- bution to the literature of systematic botany, and at the same time it will be recognized by students of forestry as an indispensable hand- book. For the latter, in this day of forestry schools and forestry courses of study in the SCIENCE. 915 colleges and universities, it is indeed fortunate that this manual has made its appearance. Without it North American dendrology was a most difficult subject for both professor and student, on account of the scattered and unco- ordinated descriptions in the botanical manu- als—the ‘Silva’ being quite too expensive a work for every-day use by students. This difficulty is now wholly removed by the pub- lication of the manual. Looking over the families which include North American trees, one finds that the coni- fers number 90 species and varieties; the palms, 10; Liliaceae, 9; the Juglandaceae, 15; Sali- caceae, 32; Fagaceae, 52; Rosaceae, 169 (of which 132 are species of Crataegus); Legu- minosae, 34; Aceraceae, 17; Cornaceae, 8; Ericaceae, 9; Oleaceae, 19. The generic and specific nomenclature is modern, so that one finds Tumion (instead of Torreya), Hicoria (instead of Carya), Toxylon (instead of Mac- lura), Malus (instead of Pyrus), Sassafras sassafras (instead of Sassafras officinale), and Catalpa catalpa (instead of Catalpa bignonio- ides). No attempt is made to cite synonyms, the author evidently assuming that the student might well trust him in the selection of the oldest available name. The author has added a handy glossary of technical terms, and the volume closes with a very full index in which English and Latin names are arranged in a single alphabetical series, thus avoiding the nuisance of two indexes, one for the common and another for the scientific names. This book suggests to one that Professor Sargent is the man to give us a similar book devoted to the exotic trees (and probably shrubs also) of which so many are now given in this country. : Cuartes KE.

The Journal of Comparative Neurology and Psychology for May contains an article of 100 pages, entitled ‘The Morphology of the Vertebrate Head from the Viewpoint of the Functional Divisions of the Nervous System,’ by J. B. Johnston, of West Virginia Univer- sity. The ‘head problems’ have recently re- o16 ceived renewed study from the standpoints of comparative anatomy and comparative em- bryology by some of our ablest morphologists, but none of these researches appears to give adequate attention to the recent phases of the doctrines of nerve components and the func- tional subdivision of the system. Professor Johnston reviews this literature ex- haustively from the new point of view and in the light of his own researches (partly not before published), discussing the problems of head morphology and segmentation with illus- trative diagrams and tabular summaries. The phylogeny of the organs of special sense is diseussed fully with reference to their primi- tive segmentation and their derivation from more primitive types of sensory mechanisms. nervous Bird-Lore for May—June contains the fol- lowing leading articles: ‘The Motmots of our Mexican Camp,’ C.

Graton exhibited photographs of Taughannock Falls, New York, and Dr. F. E. Wright ex- plained a new method of determining the opti- cal character of minerals. The regular pro- gram included the following papers: The Ore Deposits of the Ouray Quadrangle, Colo.: Dr. J. D. Irvine. The ore-deposits are located in a small area of about three and one half miles square in the precipitous country in the near vicinity of Ouray, Colo. The rocks of the region comprise a series of sedimentaries ranging in age from Algonkian to Cretaceous, with included porphyries, while the higher hills are capped by thick beds of voleanic tuff. The ores are classified as_ silver-bearing fissure veins, gold-bearing fissure veins, re- placement deposits in quartzite, replacement deposits in limestone. The silver-bearing fissure veins penetrate the sedimentaries and pass occasionally up- ward into the volcanic tuff. They carry galena, tetrahedrite and some other sulphide in a gangue of barite and quartz. Replace- ments of limestone occur where beds of this rock are penetrated by the fissures. The silver values are present in the tetrahedrite. The gold-bearing fissure veins are associated with intrusive dikes of monzonite-porphyry, and contain chiefly auriferous pyrite with some chalcopyrite in a gangue of quartz and erushed country rock. The replacement deposits in quartzite are flat shoots of gold-bearing pyrite with a little galena and other sulphides which have been deposited in quartzite. It is thought that they owe their origin to alkaline waters that have ascended to the quartzite through minute fis- sures. The quartzite is fully replaced only in the neighborhood of the fissures and is sur- rounded by empty solution cavities in the quartzite resembling those usually encountered in the limestone beds. The ores range from $30 to $600 in value. : The replacement deposits in limestone are of three kinds. One is in the limestone beds along the courses of the normal fissure veins JUNE 16, 1905.] where they form flat, lateral enrichments of such veins. 2. Large flat bodies of silica and _ barite with silver-bearing ores associated with minute supplying’ fissures. 3. Deposits of gold-bearing ore composed of an intimate mixture of pyrite and magnetite with actinolite, quartz, epidote and other minerals of supposed contact origin. This class of deposit carries low values in gold and is thought to have been deposited by replace- ment together with the associated minerals by circulating waters subsequent to the porphyry intrusions. The geological age of all of these ores is Post Eocene. Structure of the Great Plains and the Moun- tains on their Western Margin: N. H. Darton. With this communication there was pre- sented an illustration showing the configura- tion of the Dakota sandstone under the Great Plains and on the flanks of the uplifts west- ward. This widespread formation has been extensively explored in its underground dis- tribution, by numerous deep wells, and its outcrop area has been mapped so that the structure of much of the region which it underlies is ascertained. This structure was shown by 100- and 500-foot contour lines and it exhibits many notable features. In gen- eral, under the Great Plains, the formations have but little dip and wide areas are mono- - clinal. The uplifts along the mountain border and in southeastern Colorado are marked features and it has been discovered that there is a low anticline extending across north-cen- tral Kansas and western Nebraska nearly to the Black Hills. In the bottom of the basins about Denver and northeast and north- west of the Black Hills the Dakota sandstone lies below sea level. In eastern South Dakota it abuts against the Sioux quartzite and is overlapped by Benton formation. Two diagrams were exhibited, illustrating the configuration of the Black Hills and Big- horn Mountain uplifts by contour lines drawn at the surface of Minnekahta limestone in the former and Bighorn limestone in the latter.

Profound but local faults along the side of the Bighorn Mountains are notable features, due mainly to local uplift in Laramie time. Fault Phenomena Near Glen Echo, Md.: G. K. Ginpert. The locality is a disused quarry on the north bank of the Chesapeake and Ohio Canal, about one fourth mile east of Glen Echo. The rock is gneiss. It is traversed by numerous systems of joints, as many as twenty having been noted. These are inclined in various directions and at various angles. .The joints of each system are approximately parallel, with interspaces ranging from a few feet to at least several yards. The joint surfaces most broadly exposed are not true planes, but show curvature. Many of the joints are evi- dently surfaces of slipping, or fault planes, the observed dislocations ranging from a frac- tion of an inch to two or three feet. The joint systems may be classed in two series, of which one is younger than the other. Many of the joint faces of the younger series are slickensided, and some of the joints con- tain veins of quartz. The older joints show no slickensides and carry no yeins, although there is independent evidence that they are planes of faulting. Their surfaces have a faint but persistent undulation or mammilla- sion, hypothetical contours are given. east tion. Where two fault planes of the older systems intersect, each is dislocated by the movement along the other, but the dislocated parts are connected by a fluted surface suggestive of an ogee molding. This phenomenon is sup- posed to indicate simultaneous (or alterna- ting) movement on the intersecting planes while the rock was within (or at the border of) the zone of flowage. Similar movement in the zone of fracture produces splintering or crushing at the intersections. The joint systems are interpreted as the re- 918 SCIENCE. sults of successive strains distributed through a long period, the older having occurred when the rock lay below the zone of fracture. Geo. Oris SMITH, Secretary. THE CHEMICAL SOCIETY OF WASHINGTON. Tue 159th regular meeting was held Thurs- day evening, May 11, 1905, in the assembly hall of the Cosmos Club. The first paper, entitled ‘Chemical Glass- ware,’ was presented by Mr. Perey H. Walker. Analyses and tests of durability and solubility of a number of beakers and flasks were given, and samples of the various glasses shown. The most suitable for chemical use were zinc boro silicates, and may be distinguished by permanent trade marks. Much of the lime alkali silicate glass sold in this country is of very poor quality. The second paper, entitled ‘A Colorimeter for General Use,’ was presented by Dr. Oswald Schreiner. The speaker called attention to the increasing use of colorimetric methods for purely analytical and commercial purposes for both organic and inorganic compounds, and also for carrying on scientific studies in physical, physiological, sanitary and agricul- tural chemistry. A colorimeter of improved form was then exhibited and described. The parts coming in contact with the liquids are entirely of glass, mounted in a camera of wood. This instrument has the great ad- vantage of speed and accuracy combined with great versatility of application to colorimetric solutions, together with simplicity in con- struction. The third paper, entitled ‘The Occurrence . of Extractives in Apple Skin, was presented by Mr. H. C. Gore. The quantities were given in which apple wax and apple vitin occur in the epidermis of the apple, both on ripe apples and on apples examined at in- tervals during growth. The method of an- alysis of apple skins for apple wax and apple vitin, stated briefly, consisted of extracting the mare of the skin with petroleum ether, followed by chloroform, the petroleum ether extracting the wax and the chloroform re- [N.S. Vou. XXI. No. 546. moving the vitin. The extracted wax was green or yellow colored, and melted at 59°- 60°. The crude vitin was a white powder tinged with green or yellow and melted at 240°-250° C. The two varieties of summer apples examined were poorer in these extract- ives than the five varieties of winter apples. The extractives were found to increase stead- ily during the growing season. In case of ripe winter apples the wax amounts to about 30 mgms. per apple, the vitin to about 60 mgms. The probable importance of such studies in connection with the disease resist- ance of fruits was discussed. Mr. F. P. Dewey exhibited a specimen of sodium ferrocyanide. A. SEMELL, Secretary.

Day in the chair in the absence of Dr. Ernest von Nar- droff. The program consisted of the follow- ing papers: Purposes and Plans of the Solar Eclipse Expe- dition of August, 1905: S. A. MircHeEtt. Dr. Mitchell gave an outline of the plans of the various expeditions to be made to observe the total solar eclipse which takes place next August and which will be visible in Labrador and Spain. He also spoke of the different problems that the members of the expeditions will endeavor to solve. The U. S. Naval Ob- servatory expedition which Dr. Mitchell will accompany will go to Spain on the U. S.. cruiser Minneapolis early in the summer. The paper was illustrated by lantern slides. Variation of the Duration of Afterglow with Change of Electrical Intensity and Fre- quency of Oscillation of the Electrodeless Discharge: C. C. TRowsrince. A long-continued study of the duration of afterglow has shown that smooth curves can be readily obtained showing the variation of the duration of the afterglow with change of pres- sure of the gas. It has been found that the maximum of duration of these curves, when ee JUNE 16, 1905.] the electrical intensity is small, is at the same pressure approximately as the minimum spark- ing potential of the electrodeless discharge, or the point at which the discharge is most easily started. Also, when the frequency of the dis- charge is altered by a change of capacity, the position of the maximum point of the duration curve is altered to correspond to the displace- ment of minimum sparking potential of the discharge. Lengthening the spark gap and thereby in- creasing the electrical intensity inside of the vessel in which the discharge takes place changes the form of the duration curve, and when the electrical intensity is thus increased above a certain amount the curve obtained is completely altered in form. When the after- glow in the rarefied air is allowed to diffuse into a vessel cooled to liquid air temperature, the duration curve is displaced some distance towards the higher pressure and is also changed in form, other conditions being the same; otherwise, the duration of the afterglow, which in the experiments was approximately thirty seconds, was found to be little different than when the air is at normal temperature. That a long-enduring glow can be obtained at the low temperature of liquid air and a pressure approximately one tenth of one millimeter is obviously important in its bearing on problems of astrophysics.

Trowprince, Secretary. THE AMERICAN CHEMICAL SOCIETY. NEW YORK SECTION. Tue eighth regular meeting of the New York Section of the American Chemical So- ciety was held at the Chemists’ Club, 108 West 55th St., Friday, May 5, at 8:15 p.m. The chairman, Dr. Wm. J. Schieffelin, presided. The program of the evening was as follows: An Improved Form of Viscosimeter for the Testing of Oils: Dante D. Jackson. SCIENCE. 919 The earlier forms of instruments for the determination of the viscosity of oils con- sisted of bottles or bulbs which delivered a cer- tain quantity of oil through an orifice of defi- nite size. The necessity for jacketing such instruments soon became evident, and various methods were employed for this purpose. In only a few cases, however, has any attempt been made to protect the orifice so that a uni- form temperature at this point would be as- sured, and in the cases where the orifice has been protected the oil under examination has been allowed to flow into a vessel which was outside the instrument. This causes a fall in temperature from the beginning to the end of the operation which is very considerable. A form of apparatus designed by the author for the testing of the viscosity of oil at 70° F. (21.1° C.) and 212° F. (100° C.) is so arranged that both the orifice and the oils under exami- nation are kept at an exactly uniform tempera- ture throughout the entire operation, and two very considerable errors in the results are thereby eliminated. Condensation of Succinylosuccinic Ester with Guanidine: A. W. Dox and M. T. Bogert. Various attempts were made by the writers to produce a naphttetrazine of the following structure: N sY~Y = ieee ON es The well-known quinazoline syntheses when applied to p-diaminoterephthalic acid, in which the anthanilie acid grouping is present on both sides of the nucleus, should give such a compound. But diaminoterephthalic acid proved to be very inert, and no condensations could be made with it. It was found, how- ever, that succinylosuccinic ester and guani- dine condensed to a derivative of the above naphttetrazine. The method of preparation and subsequent analyses showed the product to be 2, 6-diimino- 4, 8-dioxy-hexahydro- 1, 3, 5, 7-naphttetrazine. There is a possibility also that the compound exists in the tanto- meric form, having two amino instead of imino groups. The substance is soluble 920 only in caustic alkalies and strong mineral acids. From sodium hydrate it erystallizes as a di-sodium salt in beautiful yellow needles with green fluorescence. On the other hand, a sulphurie acid salt can be obtained in color- less rhombohedra by diluting the sulphuric acid solution with water. Synthesis of Quinazolines from 6 Nitro-acet- anthranil: H. A. Sem and M. T. Bogert. The 6 nitro-acet-anthranil was prepared by the action of acetic anhydride on acetanthra- nilic acid. It is much more reactive than the acetanthranil. It combines at once with primary amines forming first, the acid amide by direct addition, and then by loss of water passing over to the quinazolines. NO, NO, /\—C=0 /\CONHR +NH,R=>| |_ /-—NGOCH, \_/NHCOCH, oO | (7 \N—B ater bon + H,0 SG Ge The 6 nitro-acetanthranil is treated with an excess of the amine in a water solution of 1 to 3. It is brought to boiling and the ex- cess of amine is distilled off. The solution is then made acid with acetic acid and filtered. The quinazoline thus obtained is purified by erystallization from alcohol. The derivatives prepared are the methyl, ethyl, normal propyl, iso propyl, secondary butyl, iso butyl, iso amyl and allyl substitu- tions of the (2)methyl (5)nitro- (4)ketodihy- droquinazoline. These are all white erystal- line solids of high melting points; soluble in hot alcohol, slightly soluble in cold; soluble in dilute acetic acid (from which they can not be erystallized) and practically insoluble in water.

The influence was studied quan- titatively and it was found that the influence was not directly proportionate to the masses of acid present, a limit being reached in each case, although the ratio of acid to the anti- mony present was inordinately large. The maximum effect obtained was for citric acid, which retains, in solution, seventy per cent. of the antimony present. Of the acids studied, ethyl tartaric came next, then malic, while tartaric was the least energetic. The effect seemed confined to the oxy-acids, because succinic acid is without any effect and the influence of the citric acid is entirely lost when its hydroxyl group has been acetylated. The Crystallization of Sodium Iodide from Alcohols: Morris Logs. It was accidentally observed that sodium iodide is extremely soluble in methyl alcohol and was not precipitated, even on the addi- tion of considerable volumes of anhydrous ethyl ether. The alcohol solution, on cooling to room temperature, separates out crystals in long shining plates. Below 0° a voluminous mass of fine needles separates out, which are identical in composition, but different in ap- pearance from those just mentioned. Melting point, 22 to 23°. Formula, NaI.3CH,0O. Under similar circumstances, ethyl alcohol dissolves the salt and erystallizes with it in proportion, NalI.C,H,O, while propyl alcohol yields 5Nal.8C,H,O. F. H. Poues, Secretary. THE TORREY BOTANICAL CLUB. A MEETING of the club was held at the mu- seum of the New York Botanical Garden on Wednesday afternoon, April 26, 1905, with seventeen persons present and President Rusby in the chair. The announced paper by Dr. P. A. Ryd- berg on ‘The Composition of the Rocky Mountain Flora’ was omitted by reason of — the absence of the author. ‘Notes on the Wire-Grass Country of Georgia’ was the title of the paper presented by Mr. R. M. Harper. CC — ——————— JUNE 16, 1905.] The wire-grass country takes its name from the wire-grass, Aristida stricta, which is com- mon all over it. In a broad sense, the wire- grass country coincides with the pine-barrens, which constitute about two-thirds of the coast- al plain of Georgia, but for the present pur- poses the term is restricted to the Altamaha Grit region, an area of about 11,000 square miles. The climate of the region, as compared with New York City, is about 18° warmer in winter and 9° warmer in summer. The rainfall averages about fifty inches a year, and most of it falls in the growing season. The geo- graphical conditions are remarkably uniform throughout, and on account of this uniformity the flora is not very rich, only about one half as many species being known there as in the state of New Jersey, though the area is larger. The region is naturally forested through- out, but the forests are mainly of long-leaf pine, which gives little shade. Consequently, the most striking feature of the vegetation as a whole is the adaptation to sunlight, usually manifested by reduction of leaf-surface. The plants of the wire-grass country can be classified according to habitat into fifteen or twenty groups. The principal habitats are rock outcrops (constituting perhaps about one one-hundredth of one per cent. of the area), pine-barrens (over half the area), swamps, ponds, sand-hills, hummocks and bluffs, some of these with several subdivisions. Civilization has influenced the flora prin- cipally through agriculture, lumbering, tur- pentining and fires. Only a small proportion of the land may be said to be under cultiva- tion. Lumbering has little effect on the her- baceous flora, for the removal of the pine trees does not appreciably diminish the amount of shade. The turpentine operators have been practically all over that part of the country, and have done great damage to the forests. Fires sweep over most of the region every spring, being set purposely by stock-raisers to burn off the dead grass, but the fires do little damage where lumbering and turpentining operations have not been carried on. The known flora of the Altamaha Grit re- ‘tina, Taxodium imbricarium, Aristida stricta SCIENCE. 921 gion consists of about 725 native species of flowering plants, 75 weeds, 20 pteridophytes and 60 bryophytes and thallophytes. The lower cryptogams have been little studied. The largest families are Composite, 100 spe- cies; Cyperacee, 83; Graminer, 68; Legu- minose, 50; Serophulariacex, 30. Some of the commonest species of the re- gion are Pinus palustris, P. Elliottii, P. sero- Serenoa serrulata, Eriocaulon decangulare, Quercus Catesbaei, Eriogonum tomentosum, Magnolia Virginiana, Sarracenia flava, S. minor, Kuhnistera pinnata, Cliftonia mono- phylla, Nyssa biflora, N. Ogeche, Oxypolis filiformis and Pinckneya pubens. The following species are common in the wire-grass country (each being known from at least three counties), but are seemingly confined to Georgia: Sporobolus (a species with terete leaves), Rhynchospora solitaria Harper, Hriocaulon lineare Small, Polygonella Croomu Chapm., Siphonychia pauciflora Small, Viola denticulosa Pollard (with leaves a foot and a half long), Dicerandra odoratis- sima Harper, Pentstemon dissectus Ell., Bald- wina atropurpurea Harper, Marshallia ra- mosa Beadle & Boynton and Mesadenia sp. (near lanceolata). One of the most interesting features of the pine-barren flora, not generally known to botanists, is that the whole region was sub- merged beneath the sea in Pleistocene times, consequently the species now confined to the pine-barrens (from New Jersey to Texas), perhaps several hundred in number, have probably originated since that time. Mr. Harper’s remarks were illustrated by many photographs and specimens. The paper was discussed by Drs. Britton and Rusby. Mrs. Britton then spoke of certain interest- ing southern mosses, especially of Hrpodium, a curious genus having the habit of a Frul- lania or Lejeunea. A species of this collected many years ago by Sullivant at Augusta, Ga., was published by Austin as a hepatic under the name Lejeunea biseriata. Mrs. Britton discussed and exhibited also numerous mosses from the extreme southern part of Florida. 922 SCIENCE. A few of these appear to be undescribed, but most of them are of species that are widely distributed in the West Indian region. Dr. Rusby showed specimens of spurious ipecae roots which have found their way into the markets. The true ipecac (from Ceph- aélis Ipecacuanha of the family Rubiacer) is now hard to obtain and high-priced. Some of the spurious root comes from other species ot the same genus, but the most common . adulterant is from the genus Jonidium (Cal- ceolaria) of the family Violacee. Dr. Rusby exhibited also specimens of Porteranthus stipulatus, which is sometimes called the North American ipecac. Dr. Britton showed living plants of two species of Crassulacee which had come into flower in the greenhouses of the New York Botanical Garden. One was Sedum Nevii, hitherto described from dried material, a spe- cies collected originally in southwestern Vir- ginia, but since found to extend to Indiana. The other was a Pachyphytum from Mexico. Dr. Britton stated that in North America, north of the Isthmus, 284 species of Crassula- cee may be recognized, distributed in 25 genera. Representatives of all these genera have now been studied in the living state. Marsuatt A. Hows, Secretary pro tem. DISCUSSION AND CORRESPONDENCE. THE METRIC ERROR. To tue Eprror or Scrence: In your issue of March 24, Mr. Henry B. Hedrick, of the United States Naval Observatory, Washing- ton, D. C., shifts from one metric fallacy to another. The regulation school children fal- lacy, as illustrated by the Hon. James H. Southard, chairman of the Committee on Coinage, Weights and Measures, in his report to the House of Representatives in 1902, and by Lord Belhaven in discussing a compulsory metric bill in the House of Lords on February 23, 1904, is that the adoption of the metric system will shorten the school life of every child, including all branches of study, from two thirds to three years; in other words, that the eight years will be cut down to seven and [N.S. Von. XXTI. No. 546. one third or even to five years. It is on this basis that Mr. Southard estimates a saving of $1,000,000,000 in every generation. It is clearly impossible to save by the adoption of the decimal system any of the time occupied by the study of non-mathematical branches, such as physical training, penmanship, lan- guages, geography, history, nature study, drawing, cooking, sewing or music. ‘The say- ing must be made in the time devoted to the study of compound numbers, weights and measures, which occupy 20 per cent. of the school arithmetic. Applying this rate, 20 per cent., to the 344 weeks occupied during the eight years by all branches of mathematics, we find 6.8 weeks to be so consumed. ‘This estimate is not only fair, but extremely liberal to the metric system. It is based on the eight- year schedule adopted for the public schools of New York City. The weekly time of 1,500 minutes is apportioned among the different branches, and the uncertain amount of time devoted to study outside of school hours is not included. Thus there is no confusion of schedule weeks with regular weeks. The case is simple. This metric fallacy is the claim that from two thirds to three years of the en- tire school life can be saved by the adoption of the metric system of weights and measures ; when in fact, less than seven weeks is now devoted to compound numbers, weights and measures. Turning from this old fallacy, let us con- sider the new one formulated by Mr. Hedrick to the effect that the adoption of the metric system would save ten per cent. of the time devoted to mathematics, or about two thirds of what ‘may be called a mathematical year of school life. In other words, that ‘the pupil would be about a year ahead in mathematics at the end of the eight years if he had only the decimal system to learn.’ In exposing this new fallacy it is unneces- sary to dwell on the fact that the study of weights and measures in the school is merely very superficial memorizing and that the real knowledge of weights and measures is ac- quired outside of the school by using them; nor on the fact that the 343 weeks covers ~~ = — i ca ey! a Oyting-«' \. at ee JUNE 16, 1905.] geometry and algebra, from which the special study of weights and measures is excluded. We can ignore these considerations because the fallacy of Mr. Hedrick’s claim is due chiefly to his assumption that the use and study of fractions can be restricted to deci- mals. That is impossible because the uni- verse is not built that way. To save time by abolishing the study of vulgar fractions is to promote ignorance, not knowledge. Such a policy of saving, carried to its legitimate con- clusion, would do away with all study and award diplomas for what the graduate from the school of ignorance does not know. The earth, from which the French scientists a century ago thought they had derived the meter, persists in revolving on its axis 365 29928 times during one revolution around the sun. Everything from the chemical com- binations of the elements to the arrangement of the planets and fixed stars proclaims the eternal verity which John Quincy Adams thus expressed to Congress in 1821: Decimal arithmetic is a contrivance of man for computing numbers, and not a property of time, space, or matter. Nature has no partialities for the number ten, and the attempt to shackle her freedom with them will forever prove abortive. It seems like a waste of time to demonstrate this self-evident proposition, but as many, in- cluding the House of Lords and the chairman of the Committee on Coinage, Weights and Measures of the House of Representatives, have reached the opposite conclusion, it may be worth while to ask them to examine a French arithmetic. Take that excellent work by Joseph Garnier, ‘Traité complet d’arith- métrique théorique et appliqueé au commerce, a la banque, aux finance et a l’industrie.’ The fifth edition (1900) contains not merely a few incidental references, but many comprehensive chapters dealing with vulgar fractions. Here are a few chapter headings: ‘ Numeration et propriétés des fractions ordinaires,’ ‘ Reduction des fractions au méme denominateur,’ ‘ Simpli- fication des fractions ordinaires,’ ‘ Conversion d’un numbre entier, et d’une expression frac- tionnaire,’ ‘ Addition des fractions ordinaires,’ ‘Soustraction des fractions ordinaires,’ ‘ Mul- tiplication des fractions ordinaires,’ ‘ Division SCIENCE. 923 ordinaires, ‘Conversion des fractions ordinaires en fractions décimales et réciproquement,’ ‘ Fractions décimales period- iques,’ ‘ Question sur les partages proportion- nels, sur les mélanges.’ If these titles are not sufficient the metric advocate in English-speaking countries can be convinced by reading the French arithmetic and studying its problems. It includes 43 pages on the metric system; 12 pages on old pre-revolutionary weights and measures; 13 pages on the comparison of the old measures with the new; 22 pages on compound num- bers; and 86 pages on vulgar fractions. The chapter on the metric system, entitled: ‘Poids et Mesures—Nouvelles Mesures au Systéme Métrique,’ effectually dispels the illusion that the metric system in its entirety is simple. The system is explained there, not to make converts to the metric cause, but for practical application to every-day work. The metric system in the French arithmetic with its foreign nomenclature and combination of decimal with binary divisions, such as hecto- litre, demi-hectolitre, double decalitre, deca- litre, demi-decalitre, double-litre, litre, demi- litre, double decilitre, decilitre, demi-decilitre, double centilitre and centilitre, is the very uniformity of confusion. There are the same complex vulgar fractions and weird problems that one finds in all school arithmetics, only in the French form perhaps a little more weird. And all this in France more than a hundred years after the following decree was issued by Robespierre: Decree of August 1, 1793. Art. 1. The new system of weights and meas- ures founded on the measurement of the earth’s meridian and the decimal division will be used throughout the Republic. des fractions In the face of such evidence, what is left of the claim that the metric system will save two thirds of a year or two thirds of a minute in the study of mathematics in school? That the teaching of the metric system in American schools at the present time is but a pretense can be proved by asking any grad- uate a few simple questions. The fact is, that the introduction of the metric system into English-speaking countries, instead of making 924 SCIENCE. the edueation of the child easier, will make it vastly more difficult, because it will then be necessary to teach the old system, which will persist in use, and also to teach in fact as well as in name the metric system with the con- fusing ratios, direct and reciprocal, between the English and metric units. If any one wants proof of this he can find it in the same French arithmetic. One chapter, ‘Nomenclature des anciennes mesures et com- parison avec les nouvelles,’ treats of old units, a few of which are: towse, pouce, ligne, aune, pas, lieue, perche, arpent, solive, corde, setier, muid, mine, minot, livre, once, denier, grain. If he still doubts let him go to some great French industry, textile manufacturing for example, and there study the chaos of weights and measures, thus described in 1902 by Paul Lamoitier, a French manufacturer: We are as much in the anarchy of weights and measures for the textile industry as at the time of the Revolution. * * * The famous aune, do you know its equivalent? Exactly 3 feet, 7 inches, 10 lines, and 10 points, er in other words, 1.188447 meters; the foot being equal to .324839 meter and divided into 12 inches, the inch into 12 lines and the line into 12 points. You would not imagine this as you are in the habit of calling it 1.19 meters. You laugh! It is, however, no laughing matter, unless you con- sider it as I do, profoundly ridiculous. * * * I will take my oath that the manufacturer of Rouen if he has not studied each section sepa- rately, has no idea what is the standard of Reims or the denier of Lyons or Milan. And on the other hand the manufacturers of Reims and Lyons are likewise puzzled in making comparisons of the diverse numberings of the diverse materials. Such is the condition of French weights and measures at the present time. The evidence here presented is from French sources and makes ridiculous not only the claim of say- ing in education, but the whole metric proposi- tion as well. This school children fallacy is confined to English-speaking countries where in the absence of experience with the metric system the imagination supplies the founda- tion for argument. The French labor under no such delusion. Of course, if they insist, English-speaking countries can learn about the metric system [N.S. Von. XXI. No. 546. in the high priced school of their own experi- ence, but more than a century of experience in France can be had without money and without price. Samuet S. Date. Boston, Mass., March 27, 1905. WILL THE METRIC SYSTEM SAVE TIME IN EDUCATION 4 In the article entitled, ‘The Metric Fallacy,’ Science, March 3, p. 353, is the statement that, in the New York public schools: ‘The time allotted for all branches of mathematics amounts to 341 weeks for the eight years.’ These figures relate to the actual time spent in recitation, which extends through nearly one year of school life, that is, about one eighth of the entire time. A complete educa- tion, to which Lord Kelvin referred in the British Parliament, includes high school and college, eight years more, which, with the same division of time, gives two years of solid mathematics. In England, one sixth, instead of one eighth is given to mathematics, and it is not extravagant to say that one half of this is wasted because of our barbarous weights and measures. Part of the economy of time shown in this country is due to our decimal money, part to the disuse here of many of the old English measures still taught in the Eng- lish schools, and part to the greater use here of the metric system in our higher education, or perhaps it would be more correct to say, the non use therein of the English system.

It was situated directly over the voleano’s conduit, and numerous explosions occurred in its sum- mit portion. The latter, 7. e., the ‘ obelisk,’ was situated on one side of the dome and rose as a mighty tower to a height of more than a thousand feet above it. While the two struc- tures just referred to have been described as distinct, perhaps in part for convenience in recording observations, there seem to be good reasons, as will be stated below, for consider- ing them as parts of the same massive-solid extrusion or, as termed by some writers, “eumulo eruption.’ In explanation of the upheaval of a mighty spire or obelisk of rigid rock from within the crater of Mont Pelé, two hypotheses have been offered. The obelisk has been considered by several geologists as the freshly congealed and rigid summit portion of a column of molten rock or magma, which was forced out of its conduit in a massive-solid condition. wa A — SCIENCE. 960 “syeuuray yo sdnoad Joyjo uy suoyOUNy pus suBs.o ITA WOSTAVdTTOD UT SB [[AAL SU (SOTJOTITA ‘soroods ‘vaoued ‘satjrurey ‘sxopiu ‘sassulo *9 2) sdnowh “oyjo YT aostivdio0o ur suvsio 10 sdnoid urejy100 JO ssouyqty _— yan “ae UOTy -viper oaydepe, 10 ,a0UaTIaAIp , UL Sutjpnset uornerjuesayip pus uoleztperods Sursvatouy “7wobwoany ‘SQODOTVNY-NON ‘TIT Se. “aourbaa -u09 ut Saypnsar ‘adéy Jo aoreu -txoidde xo Ajirejrcais Avepuooas & Sarsnved ‘suph10 10 sypurup paywjpacun 40 wnjvunssip at jyuepuedepur Sar -slie suoTeydepe reprMig §"7wahwaanog 4 ’ 5 . 5 JUNE 23, 1905.] elected president of the club for the ensuing year.

The Scottish Geographical Maguzine states that an expedition has recently started with the object of thoroughly investigating the oceanography and ‘biology of the region be- tween India and Madagascar. The vessel employed is H.M.S. Skylark, under the com- mand of Captain Boyd Somerville, who is accompanied by two civilian men of science, Mr. Stanley Gardiner and Mr. Forster Cooper, both of whom have already been engaged in scientific work in the area under investigation. The Skylark is to go first to the Chagos Archi- pelago, then to Mauritius, which it is expected will be reached about August 1. The voyage will then be continued via the Cargados reef to the Seychelles, whence the return will be made to Colombo, the starting-point. Messrs. Gardiner and Cooper are to be left at the Seychelles, where they hope to spend some months in scientific work, returning home in January, 1906. It is stated in Nature that at the forty- second general meeting of the Institution of Mining Engineers, held in London on June 2 and 3, several interesting papers were read. Mr. T. Y. Greener dealt with the firing of boilers by waste heat from coke ovens. Mr. M. R. Kirby deseribed the compound winding engine at Lumpsey iron mine. Its steam consumption is only 38 pounds to 40 pounds per indicated horse-power hour. Mr. F. Hird gave the results of tests of the electric wind- ing engine at Friedrichshall, and Mr. E. Lozé deseribed electric winding engines installed at French collieries. Mining education in the United States was discussed by Professor H. Eckfeldt, and in New Zealand by Professor J. Park. Coal mining in India was dealt with by Mr. T. Adamson. Mr. J. Jeffries described the occurrence of underground fires at the Greta colliery, New South Wales. Mr. W. C. Blackett and Mr. R. G. Ware described a striking innovation in mining practise, the use of electrically driven mechanical convey- ors for filling at the coal-face. Two years’ experience has shown a saving of 48 per cent. over the ordinary pick and shovel method. 968 Lastly, Mr. A. R. Sawyer gave an account of the geology of Chunies Poort, Zoutpansberg, Transvaal. Incidentally, he mentioned some old copper workings where native copper oc- curs in some abundance in dolomite. Tue Naturwissenschaftliche Verein at Karlsruhe has, thanks to a considerable legacy, been placed in a position to establish two new stations for seismic observations, the one in an underground passage at Turmberg, near Durlach, the other in Freiburg. Tue London Times states that a large com- pany assembled in the Oxford University Museum on May 31 at the annual conver- sazione of the Junior Scientific Club. An attractive program had been arranged. Pro- fessor E. B. Poulton, F.R.S., delivered a lec- ture on ‘Some Recent Work on Protective Resemblance and Mimicry in Insects, and Dr. A. E. Tutton displayed some of his latest lantern slides of Alpine scenery. There were demonstrations of the properties of radium and spinning tops, experiments on color, and an exhibition of thermit and high tempera- tures, which included the making of artificial diamonds. Messrs. Zeiss exhibited their in- strument for seeing ultra-microscopic par- .ticles, and there was a working installation of wireless telegraphy. The Pitt-Rivers Mu- seum was thrown open, and music was pro- vided by the band of the Grenadier Guards.

THE THE proposed affiliation or alliance of the Massachusetts Institute of Technology with Harvard University was, as we have already reported, approved at a meeting of the corporation of the institute on June 9. Thirty-two of the forty-seven members of the corporation were present, and by a vote of 20 to 12 it was agreed to accept the terms of the agreement drawn up by the committee of the two institutions. Before the agreement can become effective the corporation and overseers of Harvard University must take action and several legal questions must be passed upon by the courts. It will be remembered that on May 5 the faculty of the institute adopted by a vote of 56 to 7 the report of the com- mittee adverse to the affiliation. A full account of the report adopted by the fac- ulty and of the minority report, together with an account of the meeting of the alumni on May 4 has been published in a special issue of The Technology Review. In view of the great importance of the proposed merger for university develop- ment and technological education we re- produce here: (1) The agreement pre- pared by President H. S.. Pritchett and Professor A. Lawrence Lowell on behalf of the institute and Dr. H. P. Walcott and Charles Francis Adams, 2d, Esq., on behalf of the university, now adopted by the cor- poration of the institute; (2) the will of the late Gordon McKay in so far as it re- lates to his bequest to Harvard University, d70 : SCIENCE. and (3) extracts from the report adverse to the alliance adopted by the faculty of the institute and extracts from the minority report. AGREEMENT BETWEEN HARVARD UNIVERSITY AND THE MASSACHUSETTS INSTITUTE OF TECHNOLOGY. Harvard University and the Massachu- setts Institute of Technology, being con- vineed, after a careful consideration of the conditions which affect the work of educa- tion in industrial science, that such work can be greatly advanced and enlarged by a cooperation of the two institutions, in order to secure mutual assistance, render possible a larger enterprise, promote econ- omy, avoid duplication and competition, and give to the purpose of donors who have bestowed money in trust for that object a fuller accomplishment, do make this agree- ment, which shall endure so long as it shall be found to serve, to the satisfaction of both institutions, the objects above de- elared. But, whereas the carrying out of such agreement will require the employ- ment of the income of the funds which the University holds, or will hereafter hold in trust, and the University feels that faith- fulness in the performance of these trusts which it has accepted is its first duty, to which all other considerations must yield, this agreement shall not go into effect until and unless the University shall have ap- plied to the Supreme Judicial Court for instructions and the court shall have made a decree that this agreement may be carried out without violation of its duties as a trustee and in accordance with law and equity. I. The organization of the University, the organization of the Institute, and the title of each to its property and funds shall re- main unaffected by this agreement, as shall also the rights and duties of each in invest- ing and managing its funds. i i The institution for the combined work of promoting and furnishing education in in- dustrial science, which it is the object of this agreement to establish, shall retain the name of the Massachusetts Institute of Technology ; it shall be under the direction of an Executive Committee, and the in- struction therein shall be given by a Fac- ulty, which two bodies shall be constituted as herein below provided. Lau The said Executive Committee shall con- sist of nine persons, to be designated by the Massachusetts Institute of Technology, of whom two shall be the President of the Corporation of the Institute and the Treas- urer of the Institute, and three shall be members of the Corporation of the Uni- versity. Subject to the restrictions herein below expressed, the said Executive Committee shall have the general administration and superintendence of all matters concerning said combined work, including the appoint- ment of officers of instruction and govern- ment, and of servants, the power to remove any of them, the fixing of their salaries and the prescribing of their duties, the care of buildings, property, and equipment, the appropriation of money put at its disposal under this agreement, the fixing, collecting, and expending of students’ fees, and the supervision and direction of the work of the Faculty, these being substantially the powers now conferred on the Executive Committee of the Institute by its by-laws; it being, however, expressly provided that all appropriations from money furnished either by the University or by the Institute, and all proposed appointments or removals of officers whose salaries are to be paid [N.S. Vou. XXI. No. 548. JUNE 30, 1905.] therefrom, shall be submitted to the Cor- poration concerned and approved by it be- fore being finally adopted, it being under- stood that students’ fees shall be deemed to be furnished by the Institute, and that no change shall be made in those fees with- out its approval. The said Executive Committee shall keep records of its proceedings, and shall make reports to the Corporation of the Univer- sity and the Corporation of the Institute annually, and at such other times as either Corporation may request. LV. The President of the Institute for the time being shall be the President of the said Executive Committee, and shall pre- side at its meetings, when present. His salary, as fixed by the Corporation of the Institute, shall be paid from the funds fur- nished by the Institute. He shall be the Chairman of the Faculty, shall have the superintendence of the several depart- ments, and shall act as general executive and administrative officer, subject to the direction and control of said Executive Committee. He shall annually make a re- port to the Corporation of the University and to the Corporation of the Institute. Whenever a person shall vacate the office of President of the Institute, he shall there- upon cease to be a member of the said Executive Committee. iV: The Treasurer of the Massachusetts In- stitute of Technology shall be ex officio the Treasurer of the said Executive Committee. He shall, as Treasurer of the said Execu- tive Committee, have charge of the funds put at the disposal of said committee, shall make such payments as the committee may authorize, shall keep accurate accounts of all money received and expended, and shall make report of his doings annually, or oftener if required, to the said committee, SCIENCE. 971 and to the Corporation of the University and to the Corporation of the Institute. VI. The Faculty shall consist of all the pres- ent professors, associate professors, and as- sistant professors of the Institute, and all professors, associate professors, and assist- ant professors of the University who now give courses of instruction leading to de- grees in industrial science, and such officers hereafter appointed as said Executive Com- mittee may designate. The present pro- fessors, associate professors, and assistant professors of the University as aforesaid shall not be removed nor. have their present salaries reduced without the consent of the Corporation of the University. Subject to the supervision and direction of the said Executive Committee the Fac- ulty shall have charge of instruction and discipline. Var. Subject to the reservations hereinafter set forth the University shall place at the disposal of said Executive Committee, as above provided, the net income of all funds which are now credited on its books to the eredit of the Lawrence Scientific School, also the use of all machinery, instruments, and equipment which the University holds, and the income of all property which it may hereafter acquire for the promotion of instruction in industrial science, and also three fifths, but no more, of the net income which may accrue from the bequest and devise of the late Gordon McKay. Wen: Subject to the reservations herein set forth, the Institute shall place at the dis- posal of the said Executive Committee the net income of all funds and the use of all property and equipment which the Insti- tute may hold for the promotion of instruc- tion in industrial science, reserving only 972 SCIENCE.

(From the Boston Transcript.) such amounts and property as it may re- quire to maintain its organization and to carry on such functions as may remain to it independently of the promotion of indus- trial science. Dx In so far as money contributed by either Corporation under this agreement may be used by the said Executive Committee for the purchase of equipment or supplies, the JUNE 30, 1905.] title thereto shall be in the Corporation whose money is appropriated therefor. xe The site of the institution shall be in Boston on the right bank of the Charles River, as nearly as practicable opposite to Harvard Square, and the Massachusetts Institute of Technology shall there erect, furnish, and equip buildings having the capacity of at least its present buildings. But the Institute shall not be required to proceed with such purchase and construc- tion until it shall have sold a sufficient part of the land which it now owns. Provided, however, that this agreement shall be avoided if at the end of four years from the time when this agreement goes into effect the Institute shall not have purchased said land and proceeded to a substantial extent with such construction. Das Within three years after the Massachu- setts Institute of Technology begins the construction of such new buildings, if the Institute is then prepared to give in its new location to the students of the Lawr- ence Scientific School all needed instruc- tion in industrial science, the Lawrence Scientific School shall be discontinued as a separate school of industrial science so long as this agreement remains in force. DOT, The degrees of Bachelor, Master and Doctor in Science, so far as given in indus- trial science, and all degrees in engineer- ing, together with the requirements of courses of study leading to these degrees, shall be within the province of the Fac- ulty; and these degrees shall be conferred by the Corporations of the University and the Institute, acting separately. Ui Male students in the Institute shall have the same privileges as students in Harvard SCIENCE. 973 University in the use of the playgrounds, museums, and libraries of the University. Under regulations to be made by the two Corporations, and on payment of proper fees, students of the Institute shall be ad- mitted to courses of instruction and the use of laboratories of the University, outside of those pertaining to industrial science, and students of the University to the courses and use of laboratories of the Institute. XIV. The Corporation and Overseers of the University and the Corporation of the Massachusetts Institute of Technology shall each have full right at all times to inspect the institution, and suggest to the said Executive Committee changes in the meth- ods of management. XG The Department of Architecture in the University and in the Institute respectively are not included in this agreement, but re- main unaffected hereby. XVI. It is expressly provided that, as regards the funds and property of the University and of the Institute respectively, this agreement shall be subject to any special terms and requirements upon which such funds and property may be held; and any property or funds which may be held at any time by either Corporation under such terms and restrictions as would prevent the use of them in the precise manner contem- plated by this agreement shall, neverthe- less, be used by the two Corporations re- spectively for the support, benefit, or en- couragement of the scheme agreed upon, in such manner as may be permissible and in accordance with the trusts upon which they may be held. XVII. The arrangements established by this agreement may be terminated at any time 974 either by the President and Fellows of Harvard University or by the Corporation of the Massachusetts Institute of Tech- nology, upon reasonable notice to the other Corporation. In the event of the termination of this agreement, the Massachusetts Institute of Technology must pay, at such prices and upon such terms as the parties may agree upon, and, if they can not agree thereon, as may be fixed by arbitration (usual arbi- tration clause), for any buildings or fix- tures upon said site, paid for with funds furnished by the University. XVIII. This agreement shall take effect when finally adopted and approved by the Cor- poration and the Overseers of the Univer- sity and the Corporation of the Institute, and when and if a decree of the Supreme Judicial Court, as provided for in the pre- amble hereof, shall have been obtained. EXTRACT FROM THE WILL AND CODICILS OF THE LATE GORDON McKAY. I direct that eighty per cent. of the bal- ance of said net annual income, after pay- ing the annuities (the remaining twenty per cent. being held as a reserved fund to cover any future possible deficiency in the annual income to pay said annuities), shall be safely invested by my trustees from time to time until such accumulations amount to the sum of one million dollars, and then I direct my trustees to pay over said sum of one million dollars to ‘the President and Fellows of Harvard College in their cor- porate capacity,’ if said Corporation shall accept the same for the purposes and upon the terms and conditions hereinafter set forth, to be held and applied by them and their successors in said capacity for the purposes and trusts hereinafter declared. I also direct said trustees to pay to the said President and Fellows (if and after SCIENCE. [N.S. Vou. XXI. No. 548. said sum of one million dollars has been paid over to them, as aforesaid) annually eighty per cent. of the balance of the net income accruing from the remainder of my estate after paying the existing annuities; and upon and after the death of the last surviving annuitant I direct said Trustees to pay over to the said President and Fel- lows of Harvard College all the residue of my estate, including all unexpended in- come, all of which said sums I give to the said. President and Fellows of Harvard College, provided they accept the same, as aforesaid, strictly upon the trusts and pur- poses following, namely :— I direct, if the said Corporation, the President, and Fellows of Harvard College accept said gift, that the sum total of all the property and moneys conveyed by my trustees to the President and Fellows of Harvard College shall be forever known and described in the records of the Presi- dent and Fellows and on the books of their Treasurer as the Gordon McKay Endow- ment. I give the President and Fellows full powers to hold, manage, and protect, im- prove, sell, invest, and reinvest at their discretion, from time to time, the property in which this Endowment may at any time be invested. I also give the said Corpora- tion authority, in case the principal shall be at any time impaired through misfor- tune, to accumulate the income of the Endowment, or any part thereof, until the principal shall be made good; but, in order that the principal and income may share in the guaranty or insurance which is derived from the large mass and wide distribution of the University’s investments, I prefer that the investments of the Endowment be merged, as soon and as far as in the discre- tion of the President and Fellows they prudently and equitably may be, with the general investments of the other permanent funds held by the President and Fellows. JUNE 30, 1905.] The net income of said Endowment shall be used to promote applied science :— First. By maintaining professorships, workshops, laboratories, and collections for any or all of those scientific subjects which have, or may hereafter have, applications useful to man; and Second. By aiding meritorious and needy students in pursuing those subjects. Inasmuch as a large part of my life has been devoted to the study and invention of machinery, I instruct the President and Fellows to take special care that the great subject of mechanical engineering in all its branches, and in the most comprehensive sense, be thoroughly provided for by my Endowment. I direct that the President and Fellows be free to provide from the Endowment all erades of instruction in applied science, from the lowest to the highest, and that the instruction provided be kept accessible to pupils who have had no other oppor- tunities of previous education than those which the free public schools afford. I direct that the salaries attached to the professorships maintained from the En- dowment be kept liberal, generation after generation, according to the standards of each successive generation, to the end that these professorships may always be at- tractive to able men, and that their effect may be to raise, in some judicious measure, the general scale of compensation for the teachers of the University. I direct that the professors supported from this Endowment be provided with suitable assistance in their several depart- ments by the appointment of instructors of lower grades and of draughtsmen, foremen, mechanies, clerks, or assistants, as occasion may require, my desire being that the pro- fessors be free to devote themselves to whatever part of the teaching requires the greatest skill and largest experience and to SCIENCE. 975 the advancement of their several subjects. I direct that the President and Fellows be free to erect buildings for the purpose of this Endowment, and to purchase sites for the same, but only from the income of the Endowment. I direct that all the equipment required to illustrate teaching or to give students opportunity to practise, whether instru- ments, diagrams, tools, machines, or appa- ratus, be always kept of the best design and quality, so that no antiquated, superseded, or unserviceable implement or machinery shall ever be retained in the lecture-rooms, workshops, or laboratories maintained from the Endowment. Finally, I request that the name Gordon McKay be permanently attached to the pro- fessorships, buildings, and scholarships, or other aids for needy students which may be established, erected, or maintained from the income of this Endowment. EXTRACTS FROM THE MINORITY REPORT IN FAVOR OF THE ALLIANCE.* I. If the plan is not adopted, Harvard will be obliged to energetically develop the Lawrence Scientific School as a broad col- lege of applied science. With her ‘re- sources, reputation, and large body of alumni, and profiting by the lessons of experience, there is no doubt that she can make this school a success. This is abun- dantly proved by the experience of other universities which have technical schools. This school will be a rival of the Institute in the same community. II. Competition in business or in educa- tion always involves some economic waste. In edueation it is beneficial only if neces- sary to keep up the spur to endeavor. The Institute does not require competition with *This report was signed by Professors Fay, Jaggar, McKibben, Moore, Swain, Walker, and was supported by President Pritchett. 976 Harvard for this purpose, and without it will have ample competition with the rapidly growing schools of the Middle and Western States. III. Of two competing schools, either one will be better than the other or they will be different. If Harvard should build up a great technical school, though ours might on the whole be the better, Harvard would undoubtedly draw to herself many strong students. Every strong student that we lose is a distinct disadvantage to us. We should keep all the strong stu- dents, if possible, and let the weak ones go to other schools. If Harvard should make the Lawrence Scientific School a graduate school, as we understand is desired by its Dean, would not many of the strongest men who come to Boston to study engineering prefer to go where they would be associated solely with more mature men, all having completed their undergraduate courses and devoting themselves entirely to professional work, instead of coming to the Institute, where they would be associated with younger men, and with many special students, in an undergraduate school? IV. Technical education in this country is scareely fifty years old. It is not yet on the same plane with instruction in the so-called learned professions. The time has not yet come for making engineering schools generally graduate schools, lke so many of those of law and medicine. The Institute and most other engineering schools must remain primarily, for some time at least, undergraduate schools; but the level of industrial education will in the course of time be gradually hfted. The engineer, in order to reach the highest standard, will be expected to be liberally trained and yet to be a specialist. The Institute being one of many, when the uni- versity technical schools more generally SCIENCE. [N.S. Vou. XXT. No. 548. reach the standard of the Institute,—and some of them have already fully reached and perhaps in some respects exceeded it, —is there not ground for believing that the young man who desires to qualify him- self most completely for the engineering profession will seek the school which has the broadest environment, where he will be brought into relations with students of other professions ? V. The Institute having shown the way, there are now many technical schools where forty years ago there were few. A great majority of these are intimately connected with universities, and the fees at many of them are very low; they are doing excellent work, some as good work as the Institute; they have a much larger body of students; and they are turning out each year a much larger body of graduates than the isolated technical schools. The influence of these university technical schools, industrially and educationally, is increasing relatively in comparison with the isolated technical schools. May not our own influence di- minish in the course of time, as the body of alumni of the university technical schools increases in number and in influence? Will we not gain by placing ourselves in the main educational current in the coun- try, by allying ourselves with our most powerful university, especially as we can do so without sacrificing our methods or our control? VI. Competition from the West will in- erease. The industrial centre of the country is shifting. When the Institute was established, it was in New England; and even the iron industry and the mining industry were important here. As the years go by, new technical schools will be established in the West, at places like Chi- eago and Pittsburg, either independent or connected with universities. These schools may well be in closer touch with the indus- Junu 30, 1905.] tries of the country than any school in New England would be. When they shall have had time to grow to their full development, what will be the effect upon the Institute of Technology, especially if it is isolated, out of the main current of educational de- velopment, and actively competing for sup- port and students with another strong school not three miles distant? VII. If this agreement is rejected by the Institute Corporation and Harvard ener- getically develops her technical school, Harvard alumni all over the country— lawyers, bankers, merchants, engineers, men in responsible positions in the great. in- dustries—will be enlisted in an active cam- paign to promote Harvard interests as against Institute interests. By acting to- gether and giving the preference to Har- vard graduates, they may at least seriously hamper the growth and retard the develop- ment of the Institute. By allying our- selves with Harvard, we should gain the active support of this large and influential body of men instead of their opposition. VIII. By combination and cooperation instead of competition there is economy in administration; in heads of departments; in libraries and photographs; in museums and collections; in lecture apparatus and similar appliances; in buildings, especially as regards large lecture-rooms not often used; and, to a greater or less extent, in laboratory apparatus. IX. There is also an economy or an in- crease of efficiency in combination, with reference to the instructing force. With the same number of men that would be re- quired for two separate institutions a single institution would allow greater specialization in the teaching, permitting the student to come in contact with a larger number of inspiring teachers, or it would enable more than one teacher to teach the same subject, thus stimulating each to do SCIENCE. 977 his best. This stimulus would be greater if the two teachers were in one institution than if they were in two. There might, and probably would, also be an economy in the number of teachers, especially in the purely lecture courses, and, as already stated, in heads of departments. X. If Harvard energetically develops her technical school, she will probably, in course of time, have more resources avail- able than the Institute, considering her large number of wealthy alumni and their relations to the business world. The Me- Kay will provides ‘‘that the salaries at- tached to the professorships maintained from the endowment be kept liberal, gen- eration after generation, according to the standard of each successive generation, to the end that these professorships may always be attractive to able men, and that their effect may be to raise in some judi- cious measure the general scale of compen- sation for teachers of the university.’’ In the course of time, therefore, when the McKay money becomes entirely available, it seems inevitable that Harvard will have a very high standard of salaries for pro- fessors in her technical school,—probably much higher than those at the Institute. In this ease she could attract to these positions the ablest men, who ean not now afford to be teachers because of the inadequate re- ward. Whether under these conditions the Institute would be the leader in technical education in this community is at least doubtful. XI. Increase in the number of students, if accompanied by corresponding adapta- tion or organization of the teaching foree, should also conduce to economy and effi- ciency. XII. Whether the plan is adopted or not, we can limit our numbers by raising the standard. If increase of numbers is a dis- advantage, we should limit them in this 978 way rather than in any arbitrary way. By adopting the proposed plan, we retain the field, and can get all the strongest students from this community. If there are two schools, Harvard will very likely get as many as we do. XIII. The addition of the Harvard Faculty to that of the Institute would be a distinet. gain. Whether all would har- moniously work together at once is of little consequence. Temporary adjust- ments might have to be made. With broad-minded cooperation a larger effi- ciency would result by adding to our body a staff of able teachers with new ideas and without Institute traditions, but animated by ideals and purposes as high as our own. Of all men the teacher is most likely to get into a rut. In-breeding emphasizes this tendency. The influx of a body of new men with other points of view than our own would tend to counteract it. XIV. If the proposed plan should result in more intimate association between our Faculty and the Faculty of Harvard Col- lege, the result would be beneficial. XV. Institute students are given a nar- row training, and would benefit by associa- tion with men studying the humanities and the other professions. XVI. One great lack which Institute men have always felt is college life and col- lege spirit. Many of them come from their homes or boarding places in the morn- ing, attend their classes, and go home at night, seeing little of their fellows, and gaining no experience in the art of getting on with men. Their after-success will probably depend as much upon their abil- ity to deal with men as upon a knowledge of their profession, and their progress may be much retarded by a lack of some qualities which they might gain at the In- stitute if they could take the time for more intimate association with their classmates. SCIENCE. [N.S. Von. XXI. No. 548. Moving to a site out of town would give the opportunity for a change in this re- spect, since it would render possible the introduction of dormitory life. XVII. The surroundings of many of our Institute students in cheap _ boarding houses, with poor food and the temptations of a great city about them, are in many eases most unfavorable. We believe the distractions and diversions of such a life, and even the distractions in home life from the presence of friends and relatives and from home chores and duties, are much greater on the average than those which would arise under proper management in the dormitory system. The proposed plan would be an. improvement over present con- ditions, because a larger proportion of stu- dents would live in the suburbs, and be- cause dormitories might be established, which is now impracticable. XVIII. Educational institutions must depend more and more upon gifts from wealthy men. Harvard University and the Institute are in the same community. They must appeal for support to the same class of persons, and in many eases to the same individuals. If the two were work- ing together, the finanical results would be better than if the two were working sepa- rately and in opposition to each other. XIX. Rich men who have large sums of money to give away desire to have their gifts expended economieally, and, as a rule, they believe that economy results from combination and cooperation rather than from competition. If this agreement should be declined by the Institute, many of them would say that the Institute was unwilling to cooperate, and thereby in- crease efficiency and economy, while Har- vard University was willing to cooperate. This attitude would render them less likely to give to the Institute. The present plan seems to offer almost June 30, 1905.] the ideal form of affiliation. The Institute students, together with those now registered in the Lawrence Scientific School, number about 2,100; the Harvard College under- graduates number about 2,000. The tech- nieal school, therefore, would be the larg- est part of the combination, and would be subject to its own Faculty. It would seem most improbable that under these circum- stances the smaller body, the great ma- jority of whom are also earnest men, could unfavorably affect the larger and more compact professional body. XXI. The reciprocal privileges which the plan proposes would very likely be of great value to both institutions, partic- ularly in the case of advanced students. XXII. By the plan proposed we ean get all the benefits of combination and coopera- tion without relinquishing the power to do anything we are able to do under present conditions. XXIII. The plan proposed would be of advantage to Harvard for many of the reasons which have already been adduced. XXIV. The plan proposed would be of benefit to the community by giving it on the whole better advantages for technical education than could be obtained in any other way, and by enabling it to enthusi- astically support, financially and morally, a single great institution with which the name of Boston and Massachusetts would be everywhere associated. Conclusion. Weighing the arguments in favor of the plan and those. against it, we believe that those in favor decidedly outweigh those against, and that the possibilities are offered us of building up a better and a greater Institute of Technology than has hitherto existed. We believe, moreover, that the plan would be an educational bene- fit not only to the Institute, but to Harvard SCIENCE. 979 University and to the community. Boston would have one great technical school unit- ing the forces of two great institutions, and with a united community supporting it. It may be anticipated that it would not be allowed to suffer financially. The Institute would be free, under the plan, to develop in any way which might seem best, and it could do anything under the plan it can do at present, with the added advantage of MHarvard’s support. We could draw to us the strongest students not only from this community, but from other parts of the country, without suffering any of the disadvantages which would arise, as we believe, from the active competition of a neighboring and powerful school. The best way, and indeed the only way to ac- complish in full measure the greatest fu- ture for the Institute, would seem to us to lie in securing control of the field of tech- nical education in this community. EXTRACTS FROM THE REPORT ADVERSE TO THE ALLIANCE ADOPTED BY THE FACULTY. In the list of advantages to the Institute connected with the proposed agreement, removal to the Brighton location has been included by few. President Pritchett does not view it with complete favor, and opinions differ merely as to the degree of disadvantage. Apart from the financial question and the mandatory character of the agreement in this respect, the proposed site has disadvantages connected with the housing and life of the students and the problem of transportation. At present 44 per cent. of our students live at their own homes, with advantage to themselves and to the Institute. Un- doubtedly this has an important conserva- tive effect in determining the atmosphere of the Institute. Removal to a more dis- tant site would greatly decrease this num- ber, and increase the total cost of living 980 SCIENCE. to the student body. . It would also intro- duce the problem of establishing a dormi- tory system—a problem altogether too im- portant to be settled thus incidentally. A carefully devised dormitory system, it is true, might not seriously menace the pro- fessional spirit of our students; but the establishment of such a dormitory system in proximity to Harvard College would in- volve exceptional difficulties. Upon the question of transportation it may be said that the means now existing and projected, together with the increased facilities that a demand would stimulate, make the loca- tion as accessible as might be expected of any place at a similar distance from the center of Boston. On the other hand, our present site has contributed in no small degree to the dis- tinct individuality of the Institute. This site, in a busy city, is by many regarded as one of our most valuable educational assets, and has great strategic advantages. Students can live in any of the surround- ing suburbs, and can in general reach the Institute by one line of steam or electric ears without change, and are within walk- ing distance of the railroad stations; and in like manner they can go from the Insti- tute to engineering and industrial works in a wide circle of suburbs and neighboring towns. The central location attracts to our halls educational and engineering bodies that help to make a professional atmosphere, and assist in advertising the Institute to a scientific constituency of the utmost importance. Lack of Definition of the Term ‘Industrial Science,’ as Bearing upon Instruction and wpon Degrees. In connection with the proposed alliance, much has been said of the avoidance of educational duplication; but the terms of the agreement as they stand fail to make [N.S. Vou. XXI. No. 548. it clear that any definite partition has been formulated, either in scientific instruction or in the granting of degrees in science. Nowhere is there a definition of the term ‘industrial science,’ upon the exact mean- ing of which these matters depend. The interpretations of the term which have been given to us, in so far as they make matters clear, imply that the intention is to consent to continued duplication in large elementary courses and in some advanced classes, rather than to attempt the unsound and impossible separation between pure and applied science. It has been explained to us that the intention is to continue in the Institute both instruction and the granting of degrees in such branches of pure science as chemistry, physics, geology, and biology. There is reason to believe that the University contemplates the reten- tion of instruction and degree-giving in all these subjects, as well as the retention of elementary instruction in at least some branches of industrial science as College electives. The University also reserves its right to grant any and all degrees, in ap- plied science as well as in pure science; but the agreement implies that Harvard degrees in applied science would hereafter be granted only upon the recommendation of the Faculty of the Institute. The Insti- tute, on the other hand, seems to agree by implication to discontinue the granting of the Ph.D. degree, and of all degrees in other than ‘industrial science,’ which, as interpreted to us, is to inelude those branches of pure science, already men- tioned, in which degrees are at present granted by the Institute. If, as would ap- pear, the wording of Section XII. consti- tutes an abdication on the part of the In- stitute of the right to grant any degrees other than those specified, why should such an abdication be permissible on the part of the Institute when, as we are informed, JUNE 30, 1905.] the lawyers doubted whether the Univer- sity could legally divest itself of a similar right? Probability that the Earlier Years of In- stitute Work would be Absorbed by Harvard College. Disaster to the integrity of the Insti- tute’s curriculum will, it seems to us, be the logical result of this lack of definition of the term ‘industrial science,’ when it is taken in connection with the fact that the College gives, and is likely to continue giv- ing, elementary courses in mathematics, and in chemical, physical, and engineering subjects. It will be much more natural for a student intending to get an engineer- ing degree to take his elementary work in the College. That such a result is antici- pated by the framers of the agreement would appear from the statement of Presi- dent Pritchett that the stronger technical schools are to take a forward step by which they will be free from much elementary work. Two special causes are likely to contri- bute largely to this result. The first is that the tuition fee at Harvard is $100 less than that of the Institute. Even if the fees were to be equalized, at a serious financial loss to the Institute, there yet re- mains the second fact that participation in University athletics is open only to students enrolled at Harvard. Boys who are in- tending ultimately to become engineers, but who are also ambitious of athletic dis- tinction, or even those who desire the real use rather than the partial privilege of the Harvard playgrounds, would be lkely to take their elementary work in the Col- lege rather than in the Institute. Under existing conditions many parents prefer the professional atmosphere to’ the acad- emic, and send their sons to the Institute rather for that reason than because they SCIENCE. 981 have any particular engineering career definitely planned for them. It ean hardly be expected that this patronage would con- tinue under the altered conditions now pro- posed. Yet the most serious effect upon our cur- riculum, in consequence of such a change of methods, would be the loss of that absolute control over our instruction which we con- sider essential to the maintenance of our standards. If we turn over our elemen- tary scientific work to another faculty, whose educational purposes and methods are essentially different from ours, we make impossible that close coordination of studies which we consider a prerequisite of suecessful technological education. Courses of elementary instruction, actually conducted by the Institute, not only give us a rule of comparison between the scien- tifie preparation that is offered by students coming from other institutions and that which we desire and can insist upon, but they insure an advantageous uniformity of training to the great bulk of our stu- dents in those scientific studies which are the fundamentals of all technological edu- eation. We do not view any prospect of their abandonment with favor. Sacrifice of Control. A further disadvantage of the proposed agreement is the modification that it makes in the present method of government of the Institute. A new Executive Com- mittee is created, of which at least three members out of nine shall be members of the Corporation of the University. It is our opinion that under this arrangement the ‘organization, control, and traditions’ of the Massachusetts Institute of Technol- ogy would not be so safeguarded as to in- spire that confidence in the preservation of its individuality and in the continuance of its educational autonomy which we re- 982 SCIENCE. gard as absolutely essential to the well- being of the Institute and to the efficiency of iis, work? * * * The Department of Architecture. A thoroughly objectionable section of the agreement is that which excludes the Department of Architecture from its pro- visions, leaving the future of one of the original and one of the most brilliantly successful departments of the Institute wholly unsettled and problematical. * * * Loss of Alumni Interest and Support. Another disadvantage of the alliance is the danger that the interest and support of the graduates of the Institute will be sacrificed. An important element in the organic growth of an educational institu- tion is a strong, well-organized association of its alumni, the men who can best appre- ciate the advantages and needs of the insti- tution and who know the places where it can be strengthened. The Institute has such an Alumni Association, with local branches in all parts of the United States, and with a compact subsidiary organiza- tion in the form of an Association of Class Secretaries which has proved itself to be useful and efficient, and which promises to grow in importance. The alumni have shown a deep and enthusiastic loyalty, which has taken a practical form in sub- scription for the William Barton Rogers Scholarship Fund, the Walker Memorial Ruilding, and, more recently and gener- ously, for the Technology Fund. If the proposed alliance is accomplished, the in- terest of the alumni is sure to diminish with their diminished responsibility for the maintenance of the Institute, and may be altogether alienated. The loyalty of fu- ture graduates would at best be a divided sentiment. [N.S. Vou. XXT. No. 548. Conclusion. An institution which has passed beyond its formative period has a right, as a man has, to its own character and individuality. It has earned the right to grow and change along its own lines, and not to be violently wrenched out of them and made over, under new and untried influences, into something different from itself. Such a course might be justifiable as a desperate expedient in the case of a demoralized and decaying school. But the Institute is in no sense a decaying institution. While making no claim to perfection, it desires nothing so earnestly as a fuller and richer though not necessarily a larger growth. In point of numbers, however, the Insti- tute, despite a steady increase in its re- quirements for admission and an excep- tionally high tuition fee, is more than hold- ing its own, not only in Massachusetts, but throughout New England, and not only in New England but throughout the United States. Our defects—and no one is more conscious of them or more desirous to amend them than is the Faculty—are in part consequences of growth and of suc- cess. In part, however, they are inevitable defects of the qualities which have made us what we are. The lack of academic leisure and of monumental college sur- roundings, and the absence of a great part of the social and athletic life of the typical American college,—such losses are a neces- sary price which we and our students pay for the spirit of professional study, of business-like regularity, and of scientific accuracy. In the training of engineers we believe that these qualities are worth vastly more than the desirable things which we sacrifice in order to obtain them. While continuing to insist upon these qualities, we shall be glad, so far as we ean safely do so, to diminish their defects. But we believe that we ean best accomplish this by -_ — JUNE 30, 15905.] remaining free to deal with the problem by methods under our own control. With that high regard for the spirit of university life to be expected from a body of men more than half of whom, as is the case with this Faculty, have received their training from colleges and universities, rather than ex- clusively from technological schools, we are nevertheless firmly.convineed that the ef- fect of direct contact and intermingling of our student body with the dormitory, social, and athletic life of college undergraduates, under the conditions obtaining in this case, would be more harmful than beneficial, and that it would be little less than totally de- structive of the established character and atmosphere of the Institute. A successful and valuable school quite different -from ours might no doubt be de- veloped under university conditions, but that would much better be done indepen- dently, from such beginnings as already exist, rather than upon the basis of our reputation and at the cost of our individu- ality. With institutions, as with men, character is a thing which may be under- mined and destroyed, but which can not be bought or sold or transferred. The success of the Institute thus far has surely not been due to its wealth, to its superior equipment, or to large salaries paid to its instructing staff. Its suecess has been and still is a success mainly of character and morale; and it is precisely these vital qualities which the Faculty believes would be de- stroyed by the changes called for under the terms of this proposed agreement. For it is not merely proposed to remove the Insti- tute to a new site, but to graft it upon another institution. Very grave questions of policy would at onee confront the new Executive Commit- tee in the problems arising from removal and from the establishment of an entirely new type of life among our students, and SCIENCE. 983 from the adjustment of working relations: with the University. The and differences within the Committee to which these questions would give rise, and ought to give rise, might under this agree- ment lead at any time to one of two things:— the rupture of the agreement, or the transfer to the University of a complete control over the working Institute by the election of a majority instead of a minority of the joint Executive Committee from the membership of the University Corporation. The adoption of this agreement would therefore plunge the Institute at once into a condition of uncertainty concerning the preservation of its individuality and con- trol,—an uncertainty probably more preju- dicial to its organic development than an immediate and entire surrender of control would be. Even the full assent of the Institute to the proposed agreement would not make it certain that the project is to be earried out. It would have still to receive the sanction of the University, the ratification of the Overseers, and to await indefinitely various legal proceedings and decisions. All these contemplated delays and uncertainties would be further aug- mented by such other contingencies and delays as must necessarily arise in carrying out so vast and complex an undertaking. This period of uncertainty, extending in- evitably over five or six years, would be most prejudicial to the educational work and to the educational prestige of the In- stitute. In closing, the Faculty is glad, in ae- eordanee with a request made by the Presi- dent, to take this opportunity to state that it fully believes in the possibility of co- operation in effort between Harvard Uni- versity and the Institute, and trusts that this may be secured in the future to as ereat an extent as practicable. There are necessarily limitations to such cooperation, controversies: 984 SCIENCE. but we are convinced that it is possible, by consultation and conference, to secure a cooperation thus limited which will prove beneficial to industrial education in gen- eral, as well as to the particular work of both institutions. By the more frequent interchange of instructors, by allowing to the advanced students of each institution such privileges of instruction in the other, as may be practicable, by the common use of valuable apparatus, by the participation in University and Institute seminars of instructors and students of both institu- tions, by giving advanced courses of lec- tures to the combined classes of both insti- tutions; perhaps by mutual agreement from time to time tc relegate certain branches of instruction to one of the two; by carrying out together advanced engi- neering researches and tests,—by these, and by various other ways that will suggest themselves, much may be accomplished in harmonious effort which should be highly beneficial to both the University and the Institute. This development, however, must be a growth. It can not be forced, as the proposed agreement would attempt to force it, for it is in the nature of con- tinuous experiment, presenting problems for the solution of which no data exist. SCIENTIFIC BOOKS. Madreporaria, Parts III. and IV. By J. Srantey Garprner, M.A., ete. (From ‘ The Fauna and Geography of the Maldive and lLaccadive Archipelagoes, Vol. IL, Supplement I., pp. 933-957, pls. LX X XIX— XCTIIT.) The first installment of Mr. Gardiner’s re- port on the Madreporaria from the Maldive and Laccadive Archipelagoes has already been reviewed in the columns of this journal.* The second installment, which has just been received, contains an account of the Fungida and Turbinolide. *Vol. XX., No. 511, pp. 503-505, October 14, 1904. [N.S. Vou. XXI. No. 548. III. Fungida.—548 specimens, besides a number of young forms and fragments, were obtained. These are divided into 27 species and 2 varieties, representing 15 genera; against 24 species and 9 genera reported by Klunzinger from the Red Sea, and 15 species and 7 genera found by the author in the Pacific. The following is a list of the genera with the number of species referred to each, and the names of the forms considered new: Psammoseris, 1; Siderastrea, 4, S. maldi- vensis, nov.; Agaricia, 1, A. ponderosa, nov., + var. minikoiensis, nov.; Fungia, 3; Podo- bacia, 1; Halomitra, 1; Herpetolitha, 1, H. simplex, nov.; Cycloseris, 2; Diaseris, 1; Pavonia, 1; Leptoseris, 3, L. incrustans, nov.; Echinophyllia, 1; Pachyseris, 1; Coscinarea, 2, C. donnani, nov.; Psammocora, 4; P. di- varicata, Nov. Mr. Gardiner does not follow yon Maren- zeller in referring Stephanoseris to the syn- onymy of Heterocyathus and Psammoseris to that of Heteropsammia, but combines Ste- phanoseris and Psammoseris under the latter name. He goes further and puts the type species of Psammoseris (P. hemispherica) in the synonymy of the type species of Stephano- seris, which was originally described as Heterocyathus rousseanus. I somewhat doubt the correctness of the generic determination of Siderastrea clava, S. lilacea and 8S. maldivensis. Mr. Gardiner calls attention to these ‘having in their sur- face parts the thece of neighboring calices quite separate from one another, joined to- gether only by cost, instead of fused to- gether into a single dividing wall’ This dif- ference did not escape his attention. Mr. Gardiner himself doubts his Agaricia ponderosa really being an Agaricia. I feel rather confident that it is not an Agaricia. The type species of the genus is A. undata (Ell. & Sol.) Lamk; the type specimen is in the Hunterian Museum, Glasgow, where I have seen it and Professor J. Graham Kerr has kindly sent me photographs. The genus can be briefly characterized as follows: Corallum compound, thin, foliaceous. Common wall imperforate, naked, finely striate; no differen- EEE — - —_— ee JUNE 30, 1905.] tiated corallite walls. Calices forming more or less definitely concentric series, which are bounded below by a subealicular swelling or ridge; there is no swelling or ridge above, the septo-coste running directly to the next series. Septa well developed, distinctly radiate, im- perforate. Columella a_ single tubercle. Agaricia fragilis (Dana) agrees in. generic characters with the type and is a closely re- lated species. I think that Mr. Gardiner’s criticism of Professor Déderlein’s monograph, ‘ Die Koral- lengattung Fungia,’ is in some respects too severe. He says: “It is quite clear that that author [Déderlein] has, generally speaking, no scientific basis for his description of ‘ va- rieties.’” The word variety is difficult to de- fine in a manner that will be satisfactory to all systematists, and Mr. Gardiner himself is guilty of an inconsistency. Under Fungia dentigera, he speaks of ‘a true variety, the separating characters of which are discon- tinuous. If the characters are discontinu- ous, the specimens belong to a distinct species. Mr. Gardiner in Part I. of his ‘ Madreporaria of the Maldives and Laccadives’ says ‘ dis- continuous or specific’ variation. Variation in corals is so complex and its causes are so little understood that one should be very lenient in criticizing the efforts of a fellow worker to handle its phenomena. ‘There are mistakes in Doéoderlein’s work; some of his varieties can not be maintained by any of the usually accepted canons of zoological nomenclature, but his work is earnest and he has much advanced our knowledge of the genus F'ungia. I am glad to see that Mr. Gardiner con- siders Podobacia a valid genus, and heartily agree with him in that course. As regards Cycloseris and Fungia, I agree with Déderlein. The only possible basis for their separation into two genera would be in Cycloseris having originally only six primary septa and Hungia twelve. The validity of this character is extremely doubtful, as it rests on a very slim foundation. Without entering into a discussion of my reasons, I will state that I believe Quelch was correct in uniting Cycloseris and Diaseris, SCIENCE, 985 and, as stated in what precedes, I agree with Déderlein in combining both with FPungia. IV. Turbinolide—The number of. speci- mens collected is not given. Six species, rep- resenting 4 genera, are referred to the Tur- binolide. They are Flabellum, 2, F. multi- fore, nov.; Tropidocyathus, 1, T. cooperi, nov.; Heterocyathus, 1; Paracyathus, 2. Mr. Gardiner’s paper is an important con- tribution to the literature of reef corals. He gives valuable notes on variation, careful de- seriptions and figures all the forms described as new and several of those referred to pre- viously described species. The studies being made on the coral faunas of the Pacific and Indian oceans are bringing out many interesting facts of their geograph- ical distribution. I have just completed a study of the Hawaiian Fungida, and may be pardoned for comparing them with those from the Indian Ocean. The following is a list of the species, with notes on their occurrence elsewhere: Fungia (Oycloseris) patella (Ell. & Sol.), east coast of Africa, ete.; Fungia (Diaseris) fragilis (Aleock), Indian Ocean; Fungia scutaria var. dentigera Leuckart, Indian Ocean, ete.; [FPungia oahensis Déder- lein; Fungia paumotensis Stutchb. (fide Quelch), Philippines, ete.; FPungia echinata (Pallas) (fide Studer)]* Indian Ocean, ete.; Bathyactis stephana Alcock, Indian Ocean; Stephanaria stellata Verrill, Panama; Ste- phanaria n. sp.; Pavona varians Verrill, aff. P. repens Briiggemann; Pavona n. sp.; Lep- toseris (1) n. sp., aff. LZ. fragilis M. Ed. & H.; Leptoseris (2) n. sp.; Leptoseris (3) n. sp., aff. L. papyracea (Dana); Leptoseris (4) n. sp.; Psammocora, aft. P. superficialis Gar- diner. A fair proportion of the species actually occur in the Indian Ocean, some as far west as Africa, or have there analogues so similar that specific separation is doubtful. As would be expected, the Panamic fauna is represented to some extent. T. WAYLAND VAUGHAN.

Macxim Marriott and C. G. L. Wo tr. Administration of brombenzol to dogs re- sulted in increased elimination of nitrogen and urea. Urea closely followed total nitro- gen. Preformed ammonia was decreased. Creatinin elimination was not appreciably affected. Total sulfur excretion was not in- creased, but there was almost complete sup- pression of alkali sulfates. Excretion of neutral sulfur, represented for the most part in this case by parabromphenyl-mercapturic acid, was increased 400 per cent. Ethereal sulfate elimination was markedly increased. Total sulfate-sulfur was diminished. Excre- tion of chlorin and phosphorus was practically unaffected. Nitrogen and fat were increased in the feces. The drug caused ulceration of the stomach and intestines, and degeneration of the liver and kidneys. * Non-resident member. 7 The abstracts presented in this account of the proceedings have been greatly condensed from ab- stracts given to the secretary by the authors themselves.

On Experimentally Produced Variations in the Energy of Tumor Growth: Leo Lors. (Pre- sented by James Ewing.) The author’s observations point to the gen- eral conclusion that it is possible to cause an experimental increase or decrease in the en- ergy of tumor growth. Such variations may be brought about by direct stimulating or de- pressing influences on the tumor cells. The stimulation effects may become cumulative. Demonstration: Photographs and Plumage- charts of Hybrid Poultry, with Remarks: Cuartes B. Davenport. Dr. Davenport exhibited photographs and plumage-charts of four hybrids between dif- ferent races of poultry, and also of their parents, and remarked on the nature of the inheritance illustrated by each example. Experimental Cirrhosis of the Liver: RicHarp M. Pearce. (Presented by Eugene L. Opie.) Necrotic lesions were produced in the liver of the dog by injections of hemolytic immune sera of high hemagglutinative power. The author’s observations have demonstrated that cirrhosis may follow extensive primary de- structive lesions produced in this way (a view not yet fully accepted) and thus support the contention of Kretz that cirrhosis is essen- tially the result of a series of repair processes following repeated injuries of liver paren- chyma. Experimental Arteriosclerosis: Ricuarp M. Pearce and E. McD. Stanton. (Presented by J. E. Sweet.) Intravenous injections of adrenalin produce in rabbits vascular lesions that are limited to the aorta and that exhibit more or less definite sequence.’ Five to six injections of 3 to 25 minims of 1-1,000 solutions every 24-48 hours for long periods cause at first histologically important changes in the media. After about 12-15 injections very definite lesions are evident macroscopically. In the experiments continued for 6-8 weeks, the process becomes very diffuse and small dila- tions of the thinner portions of the aorta as- sume the appearance of aneurisms. At this stage the destruction of the elastic fibers is haa « "a=, - —_—_——- JUNE 30, 1905.] extreme and all degenerated areas are in- filtrated with calcium salts. Whether the vascular changes are due to a primary toxic action of the adrenalin or whether they are the result of the increased arterial tension which it causes, has not been determined. On the Chemical and Physiological Properties of Ricin, with Demonstrations: Tuomas B. OsporNE and LarayetTE B. MENDEL. The most active preparation proved fatal when administered subcutaneously to rabbits in the small dose of 0.0005 malligram per kilo of body weight. The toxic constituent of the castor bean appears to be an albumin.

By tryptic digestion the agglutinating power of pure ricin may be greatly impaired or destroyed. The experience of the authors lends no encouragement to at- tempts to ‘purify’ such toxins by methods designed to eliminate proteid substances from the active materials. On a Method of Determining Indol, with Demonstrations: C. A. Herrer and M. Loutse Fosrrr. The authors described a rapid and accurate means of determining indol. It is based on the fact that indol, in slightly alkaline solu- tion, readily condenses with naphthoquinon sodium mono-sulfonate and forms a_ blue crystalline compound that is only very slightly soluble in water but is readily extracted by chloroform from a watery solution or suspen- sion. The condensation product is di-indyl naphtho-ketone mono-sulfonate. Its solution in choloroform is red. The method is well adapted for colorimetric or gravimetric deter- minations. Anesthesia Produced by Magnesium Salts, with Demonstrations. A Preliminary Com- munication: 8. J. Metrzer and Joun Aver. The authors exhibited two guinea pigs which were deeply narcotized by subcutaneous injec- tions of magnesium sulfate. One of these animals had been similarly narcotized twice SCIENCE. 987 before and fully recovered each time. If the dose of magnesium salt is not too large, heart beat, blood pressure and respiration remain nearly normal during periods of narcosis in which any operation can be performed without resistance. Certain maximum doses can not be exceeded without causing extremely toxic effects. Enzymes and Anti-enzymes of Inflammatory EHaudates; Eugene L. Opts. Inflammatory exudates removed from the pleural cavities of dogs one or two days after injection of the irritant (aleuronat) undergo very little change, while those removed three or more days after the onset of inflammation exhibit appreciable though slight autolysis. There is no relation between the amount of digestion and the number of cells which are present. The serum inhibits autolysis in a suspension of the cells separated by centrif- ugalization. The antilytic action of the serum is favored by an alkaline reaction, but is completely prevented in an acid medium. The serum of the exudate contains a pro- teolytic ferment’ which is. active only in an acid medium. In the later stages of such inflammations there is some diminution of the antilytiec power of the exudate. Shallow Well Waters of Brooklyn: Jamus P. ATKINSON. The author’s observations justify the con- clusions that the sandy soil of Brooklyn can not be relied upon as a safe filter for the well waters of that borough, that Brooklyn soil in populous districts seems to be nearing the saturation point for sewage, and that many of the shallow wells in Brooklyn are, there- fore, in growing danger of serious pollution. The Influence of the External Temperature upon the Viscosity of the Blood: Russpiu Burton-Opitz. The author has found that the viscosity of the ‘living’ blood can be greatly influenced by changing the external temperature. Vis- cosity was markedly increased in dogs im- mersed in water at 25° C. Warm water baths (42°-45° ©.) produced a corresponding de- erease in the viscosity. Specific gravity of the blood showed corresponding variations. 988 The Changes in the Viscosity of the Blood during Narcosis; RussELL Burron-Opirz. It was found that the viscosity of the blood is increased by deep ether or chloroform nar- cosis and lessened during light anesthesia. Specifie gravity of the blood was increased by deep and lessened by light ether narcosis. Chloroform, on the other hand, produces a slight deerease during deep and an increase during light narcosis. Hence the specific gravity can not be regarded as a-perfectly ac- curate index of the viscosity. Studies of the Effects of Radiwm on Plants and Animals, with Demonstrations: Com- municated by WituiamM J. Giss. I. Preliminary notes on the effects of radium rays on plants. C. Stuart Gager. Plants are stimulated. For this stimulus there are minimum, optimum and maximum points, depending upon the proximity of the radium to the plant, the strength, quantity and condition of the radium salt, the time of exposure and the nature and condition of the tissue. II. The action of radium rays on Amaba proteus and upon other microorganisms. Louis Hussakof. No visible effects were pro- duced, by even the strongest radium prepara- tions, during periods of observation of about an hour.. The water surrounding the animal in each experiment may have prevented ra- diant effects. III. The effects of intravenous injections of radium bromid. Russell Burton-Opitz and G. M. Meyer. Increased blood pressure, caused by general vasoconstriction, always promptly followed injection of radium prepara- tions in small dogs. This effect was soon followed by a fall of pressure, due to decrease in frequency and accompanied by irregularity of the heart. The variations in blood pressure were extreme. These effects occur after divi- sion of both vagi. Respiration gradually de- creases in frequency until respiratory paral- ysis results. A striking qualitative similarity was found to exist between the effects of pure barium bromid and radium _ bromid preparations of low activity (240 and 1,000). Radium bromid of 10,000 activity, however, SCIENCE. [N.S. Von. XXI. No. 548. differed from barium bromid in failing to cause irregularity in the action of the heart. Quantitative differences were also noted. IV. The radioactivity of the different organs after intravenous injections of radium bromid. Gustave M. Meyer. Thus far determinations have been made only on the dogs used in the experiments of Burton-Opitz and Meyer (II1). Practically all parts except the brain were found to be radioactive. The blood always manifested the greatest radioactivity. V. The influence of radium bromid on me- tabolism in dogs. William N. Berg and Will- iam H. Welker. Feeding experiments have thus far failed to show appreciable results, except an increase in elimination of total sul- fate in the urine. WILLIAM J. GIEs, Secretary. THE NEW YORK ACADEMY OF SCIENCES. OF GEOLOGY AND MINERALOGY. At the meeting of April 3, 1905, Professor Stevenson presiding, the following papers were read: The Physiography of the Adirondacks: J. F. Kemp. The Adirondacks cover some 10,000 square miles, and except for the White Mountains of New Hampshire and the Blue Ridge of North Carolina, are the loftiest summits east of the Black Hills of Sotth Dakota. They are metamorphosed Precambrian sediments and eruptives with a surrounding fringe of Paleozoics beginning with the Potsdam and ending with the Utica, except for the Glacial drift. The eastern portion is mountainous, the western a high plateau which slopes to Lake Ontario. Three peaks exceed 5,000 feet. The general profile of the mountains is serrate, but there is great variety of shape. There are two contrasted types of valleys. One type, doubtless an instance of greater geological antiquity, presents gentle slopes and great maturity of form. Its members run SECTION _east and west, and north and south, and are occupied in some cases by the larger lakes. The second type is more recent, and is due to faulting. The valleys have on one or both sides precipitous escarpments. The cliffs run JUNE 30, 1905.] northeast and southwest or northwest and southeast. A third series of breaks running nearly due north is also at times in evidence. The faults are most often the result of differ- ential movements causing even a marked sheeting of the rocks. The faults run out into the Paleozoic areas, and are shown with diagrammatic distinctness, where they have been especially described by H. P. Cushing. The problem of the drainage is of especial interest. All the waters go ultimately either to the Hudson or the St. Lawrence. The courses of the large streams follow sometimes the older type of valleys, sometimes ‘the later. Barriers of drift have often driven them from their old lines across low, preglacial divides into new ones. The courses of the Hudson and Onondaga are particularly striking illus- trations, each exhibiting one or more marked bends to the eastward. The courses of the two were described and discussed in some detail. The different types of lakes were also de- scribed including the river valleys ponded by barriers of drift, the fault valleys and the relations to the older type of depression. The nature of the ice invasion and its modi- fying effects were passed in review, chiefly along the work of I. H. Ogilvie. With a brief statement of the Post-glacial lake-fillings, ete., which have been especially set forth by C. H. Smyth, Jr., the paper closed. The Paleogeography of Mid-Ordovicic Time: CuHartes P. BrerKey. Both the Cambric and Ordovicic formations contain prominent sandstone strata alter- nating with dolomites wherever exposed in Michigan, Wisconsin, Minnesota, Iowa, IIli- nois, Missouri, Arkansas and Indian Terri- tory. The northern margin, however, is pre- vailingly more arenaceous than the southern, where shales replace many sand beds. At still greater distance, in Ohio, Kentucky and Ten- nessee, these are in turn represented by lime- stones largely. The uppermost one of the series is the St. Peter. This sandstone, as well as each of the more important ones below, is believed to rep- resent an extensive retreat and re-advance of SCIENCE. 989 the sea. Few marks of the erosion intervals are preserved. Only here and there has the mantle of sand permitted much attack upon the underlying dolomite, and the reworking of the sands themselves has obliterated most in- ternal evidence of such history. Much of the sand, furthermore, is wind- blown. This reworking by the sea and the wind is believed to be the chief cause of the extreme purity of the St. Peter. The St. Peter stage of the Ordovicic, there- fore, represents a retreat of the Mississippian sea from the vicinity of Lake Superior to probably as far as Ohio, southern Illinois and Arkansas, followed by a readvance to its original position. The northern part of the St. Peter contains a sedimentary break. In part it is both older and younger than the same formation in its southern extension, while, on account of the reworking accom- panying the sea advance, there is greater con- formity with overlying than with underlying beds. A. W. GRABAu, Secretary. At the meeting of May 1, 1905, Vice- President Hovey presiding, the following papers were read: The Pleistocene Beds of Sankaty Head, Nan- tucket: J. Howarp WInson. When visited by early explorers, the section at this locality was kept freshly exposed by the cutting back of the bluff by the sea, but for quite a period of years this has been pre- vented by the northward extension of the Siasconset apron beach, so that the face of the bluff is now covered with talus and over- grown with beach grass. The locality was visited during the summer of 1904 and considerable work done in ex- posing the section and making a collection of the fossils. This work resulted in the collection of 81 species, 21 of which had never been reported from this point, including Pandora crassidens Conrad not previously found in any horizon above the Miocene, and Serripes laperonsii Deshayes and Macoma incongrua Von Mar- 990 SCIENCE. tens belonging to the Arctic fauna of the Pacific coast and not heretofore reported east of Point Barrow. A number of facts differing somewhat from those reported by former observers were no- ticed and have resulted in a somewhat differ- ent interpretation for the phenomena pre- sented by these deposits. The deposits are not of glacial origin, for (1) numerous delicate and unworn shells oc- cur; (2) bivalves such as Solen, Venus and Mya occur in the position in which they lived with both valves together, and in the case of Venus, with the ligament in place; (3) the faunas are not mixed as would be the case if of glacial origin, the lower beds containing shoal-water species of a southern range, and the upper, deeper water species of a northern and even Arctic type. The lower beds were deposited in a shallow inlet or lagoon, as shown by such species as Mya, Ostrea and Venus and especially by numerous mud crabs and the presence of our edible crab, Callinectes sapidus, while the upper beds were deposited during a subsidence of the area contemporaneous with the advance of the Wisconsin ice sheet, as shown by the deeper water and more northern species. After the destruction and washing into the lagoon of the protecting barrier beach, as shown by the overlying rounded and pure, white sands, the ice reached and passed this point, eventually burying the beds under fifty feet or more of drift. Later, a reelevation took place, bringing the land to about its present position. Early Stages of some Paleozoic Corals; C. E. GORDON. J. E. Duerdon in the Johns Hopkins Uni- versity Circular for 1902 has endeavored to show by studies based on Lophophyllum pro- liferum that the Rugosa exhibit a hexameral plan of growth of the primary septa, in so far as L. proliferum may be taken as representa- tive. Certain studies on Streptelasma pro- fundum show a primary tetrameral plan. The fact that S. profundum is a middle Ordovicie type suggests that this is the primitive con- dition. Moreover, a careful examination of [N.S. Von. XXI. No. 548. Duerdon’s figures shows that they lend them- selves to an entirely different interpretation from that which Duerdon gives. This inter- pretation is that two of the so-called primary septa are secondary septa precociously devel- oped; that their sequence and ultimate posi- tion are the same as those for the secondary septa which appear in the corresponding posi- tions in the corresponding quadrants of a zaphrentoid coral; that the fossula and car- dinal septum are on the concave side of the corallum; and that if Duerdon’s figures be inverted they reveal a perfect similarity to a zaphrentotd coral, as far as the order of ap- pearance and the arrangement of the septa are concerned. The fact that LZ. proliferum is of Carbonic age indicates that it is a modified type of the zaphrentoid coral, the first secondary septa appearing in nepionic stages and thus simula- ting the character of primary septa. A New Lower Tertiary Fauna from Chappa- quiddick Island, Martha’s Vineyard: Tuomas C. Brown. A few years ago while studying the Cretacie deposits of Long Island, Block Island and Martha’s Vineyard, Dr. Arthur Hollick made a collection of fossil molluses and plants from Chappaquiddick Island. The fossil molluses were deposited in the Columbia University collection without being fully and carefully studied. These fossils occur in the island in ferrugi- nous concretions. They seem to have been deposited somewhere to the north of where they are now found, then moved as glacial drift, reassorted and deposited in their present position. From their lithological similarity to concretions containing undoubted Cretacie fossils found elsewhere on Martha’s Vineyard, Dr. Hollick thought that these concretions and their contained fossils must be of Cretacic age. Professor Shaler noted the occurrence of these concretions and their similarities to the Cretacie drift, but being unable to find any distinctive organic remains hesitated to set them down as Cretacic. Professor R. P. Whitfield considered that 7 JUNE 30, 1905.] these rocks could hardly be Cretacic, since the fossils were of a more recent type. A careful study of the fossils has shown that this material is not Cretacie but Eocene in age. This fauna from Chappaquiddick represents a new and distinct Eocene province, differing from all the other Eocene provinces of the Atlantic coast, but no more widely different from these than they are from one another. Although in this fauna there are several species somewhat resembling those of the provinces to the south, on the whole it would seem to be more closely allied to the Eocene of England. The genera most abun- dantly represented in these Chappaquiddick deposits, e. g., Modiola, Glycymeris, are also among the most abundant in the English de- posits. These same genera, although repre- sented in the Atlantic and gulf provinces, are there more sparsely distributed and occur with other more abundantly represented genera that appear to be altogether wanting in the Chappaquiddick deposits. A comparison of this Chappaquiddick fauna with other Eocene faunas indicates that it is of lower Eocene age, the species most closely resembling those found in this fauna being found in the lower beds of the Atlantic and gulf provinces, the Tejon of California and the lower beds of England. These deposits may possibly be of the same age as the Shark River beds of New Jersey, but being deposited in a region separated from this have no forms in common with it. But such correlation could be only conjecture. As the correlation of the well-known Eocene deposits is even yet very uncertain it is unnecessary and impossi- ble to place these beds any more definitely than simply to say that they are Lower Eocene. Structural Relations and Origin of the Limo- nite Beds at Cornwall, N. Y.: O. A. Harrt- NAGEL. The limonite at the Townsend iron mine, near Cornwall in Orange County, N. Y., is found at the base of the New Scotland beds where the latter are in contact with the Long- wood red shales. The source of the iron is evidently from the red shales but whether the contact was due to overlap or faulting has not been previously explained. Two thirds of a SCIENCE. 991 mile north of the mine the Decker Ferry, Cobleskill, Rondout, Manlius and Coeymans formations, having a total thickness of 95 feet, are found between the New Scotland and Longwood beds. In the region of the mine the strata are nearly vertical and in faulting a wedge-shaped block was forced up, bringing the red shales in contact with the New Scot- land beds. A cap of limestone has until re- cent geologic times protected from erosion the mass of soft Longwood shales which now form a steep hill, but which is rapidly being worn away. Types of Sedimentary Overlap: A. W. GRABAU. With a normal sea shore, a rising sea level will produce the phenomenon of progressive overlap, a falling sea level that of regressive overlap. If the sea transgresses slowly, and the rate of supply of detritus is uniform a basal rudyte or arenyte is formed which rises in the column as the sea advances, and whose depositional off-shore equivalents are succes- sive beds of lutytes or organic deposits (bio- genics). Types of such basal beds which pass diagonally across the time scale, are seen in the basal Cambric arenytes of eastern North America, which as the Vermont Quartzite are lower Cambric, and as the Potsdam are Upper Cambric. Again in the Basal Cretacic arenyte of southwestern United States, this is shown, these being basal Trinity in Texas, Washita in Kansas, and Dakota or later on the Front Range. Examples of this type of progressive overlap are numerous and famil- iar. On an ancient peneplain surface the transgressing sea may spread a basal black shale, as in the case of the Eureka (Noel) Black shale, which is basal Choteau in south- ern Missouri and basal Burlington in north- ern Arkansas. Regressive movements of the shore succeeded by transgressive movements give us arenytes which are enclosed in off- shore sediments and which within themselves comprise an hiatus the magnitude of which diminishes progressively away from the shore. An example of this has recently been discussed by Berkey * who finds that the St. Peter Sand- stone in Minnesota marks the interval from * See ante, April meeting. 992 lower Beekmantown to upper Stones River, which interval is represented by several thou- sand feet of calcareous sediments in other regions distant from the shore of that time. In marine transgressive overlaps, later members overlap earlier ones toward the source of supply, 2. e., towards the old-land. In non-marine progressive overlaps, later members overlap the earlier ones away from the source of supply. Thus in a growing alluvial cone, the later formed beds will extend farther out on to the plain away from the mountain. If several successive fans of this type are formed one above the other, owing to successive elevations of the source of sup- ply, only the latest beds of each delta will be found on the outer edge of this compound delta, the hiatus between the beds being fur- ther emphasized by the erosion which the last bed of the first delta underwent during the time that the early beds of the second delta were deposited nearer the source of supply, 7. e., before the last bed of the second delta covered up the remnant of the last bed of the first delta and thus protected it from further ero- sion. A good example of this type of overlap appears to be presented by the Pocono, Mauch Chunk and Pottsville beds of the Appalachian region. These formations are with exception of the negligible Greenbrier member, of non- marine origin, representing the wash from the growing Appalachians. In western Pennsyl- vania only the latest beds of each (barring portions removed by erosion between the dep- osition of the successive fans) are found rest- ing one upon the other, the interval between the beds becoming less and less toward the anthracite regions. A. W. GRasau, Secretary. SECTION OF BIOLOGY. Ar the April meeting Professor H. F. Os- born presented a discussion of ‘The Ideas and Terms of Modern Philosophical Anatomy,’ and Dr. O. R. Hay described ‘Turtles of the Bridger Basin.’ The full abstract of Professor Osborn’s paper was published in Scrence for June 23. Dr. Hay gave a brief descrip- tion of the extent of the Bridger beds and of the nature of the materials composing them. SCIENCE. [N.S. Vou. XXI. No. 548. He expressed the conviction that these deposits had not been made in a lake, but over the flood-grounds of rivers. The region was probably covered with forests, and teemed with animal life. In the streams were numerous turtles. Many species of these have been de- scribed by Dr. Leidy and Professor Cope. In the speaker’s hands are materials for the de- scription of about a dozen more species. The American Museum party of 1903 collected many specimens of the genus and these have furnished good skulls, neck, shoulder and pel- vie girdles, and the limbs. These materials confirm the validity of Lydekker’s group called Amphichelydia, and show that from it sprang the modern super-families Cryptodira and Pleurodira. At the May meeting of the section papers were presented by Professor E. B. Wilson on ‘ Observations on the Chromosomes in Hemip- tera,’ and by Professor H. E. Crampton on ‘Correlation and Selection.’ Professor Wilson’s paper presented the re- sults of an examination of the mode of distri- bution of the chromosomes to the spermatozoa in Lygeus turcicus, Cenus delius, Podisus spinosus and two species of Huchistus. In none of these forms is an accessory chromo- some (in the ordinary sense) present, all of the spermatozca receiving the same number of chromosomes, which is one half the sperma- togonial number (the latter number is in Podisus sixteen, in the other forms fourteen). In all these forms, however, an asymmetry of distribution occurs such that two classes of spermatozoa are formed in equal numbers, both receiving a ring of six chromosomes (in Podisus seven) that are duplicated in all the spermatozoa, and in addition a central one which in one half the spermatozoa is much smaller than in the other half. These cor- responding but unequal chromosomes (which evidently correspond to some of the forms- described by Montgomery as ‘chromatin nucleoli,’ and agree in mode of distribution with that which this author has described in the case of Huchistus tristigmus) may be called the ‘idiochromosomes.’ They always remain separate in the first division, which accord- JUNE 30, 1905.] ingly shows one more than one half the sperma- togonial number of chromosomes, but at the close of this division conjugate to form an asymmetrical dyad, the number of separate chromatin-elements being thus reduced from eight to seven (in Podisus from nine to eight). A reduction of the number to seven in the first division, such as has been described by Montgomery as an occasional or usual process in Huchistus and Canus, was never observed. In the second division the asymmetrical idio- chromosome-dyad separates into its unequal constituents, while the other dyads divide sym- metrically. One half the spermatozoa, there- fore, receive the large idiochromosome and one half the small, the other chromosomes being exactly duplicated in both. Correlated with this asymmetry of distribu- tion is the fact that the spermatogonial chro- mosome-groups do not show two equal micro- chromosomes (as is the case in such forms as Anasa, Alydus or Protenor, where an accessory chromosome is present) but only one, which is obviously the small idiochromosome, the large one not being certainly distinguishable at this period from the other spermatogonial chromo- somes. The final synapsis of the idiochromo- somes is deferred to the prophases of the second division, somewhat as that of the two equal microchromosomes is deferred until the pro- phase of the first division in Anasa, Alydus and some other forms. A remarkable result of the difference in this regard between the forms that possess and those that lack a true accessory chromosome is that in the former ease (Anasa, Alydus, etc.) the first division of the small central chromosome is a reduction- division and the second an equation-division; while in the latter case (Lyge@us, Canus, ete.) the reverse order manifestly occurs. The rela- tion of these observations to earlier ones by Paulmier, Montgomery and others was pointed out, with a discussion of their bearing on the Mendelian phenomena of heredity and the problem of sex-determination. Professor Crampton presented briefly some of the conclusions drawn from the results of his work upon variation, correlation and selec- tion among saturnid lepidoptera. The earliest SCIENCE. 998 studies showed that eliminated individuals, when compared with similar members of the same group that survive, prove to be more variable and of somewhat different types, although this relation between variability and selection is not a constant one. The charac- ters utilized for these preliminary studies, namely, certain pupal dimensions and propor- tions were of such a nature that they could not serve the pupa directly in any functional man- ner, wherefore it was concluded that their con- dition of correlation formed the actual basis for the selective process, formative correla- tion being also distinguished from functional correlation. That the general condition of correlation among the structural characters of pups formed, indeed, the basis for selection was further indicated by the results of a sta- tistical study of the correlations between vari- ous characteristics of pupal groups from several different animal series; although an advantage did not always appear in favor of the surviving group. On the basis of the foregoing, a gen- eral theoretical conception was developed, ac- cording to which the whole series of internal elements and the whole series of external in- fluences were regarded as involved in the determination of the general condition of cor- relation or coordination that formed the basis for selection, as adaptive or the reverse. M. A. Bicrtow, Secretary. DISCUSSION AND CORRESPONDENCE. PRE-PLEISTOCENE DEPOSITS AT THIRD CLIFF, MASSACHUSETTS. To tue Eprror or Science: It has been suggested by several writers (Shaler and Ver- rill) that Tertiary and Cretaceous deposits may occur on the floor of the sea north of their known occurrence on Marthas Vineyard and Cape Cod. ‘Their northerly occurrence on land has not been noted except for the Miocene greensands at Marshfield, Mass. (Duxbury sheet, U. S. G. S.). During the spring field season at Harvard University the writer reexamined the coast from Boston Harbor to Peaked Cliff, fifteen miles south- east of Plymouth harbor, in order to test, by 994 SCIENCE. means of the excellent cliff sections, the sug- gestion of the occurrence of such deposits. Pre-Pleistocene deposits were found at Third Cliff, twenty miles southeast of Boston, and possibly at Peaked Cliff, southeast of Ply- mouth. The section at Third Cliff shows yellow clays at the base conformably overlain by yellow and white sands and succeeded by a bed of bright red sands with an unconformity at their base. On the eroded edges of the red and white beds are deposited dark, glau- conitie and lignitic clays and sands. The entire series of beds has a total maximum thickness of sixty or seventy feet, and out- crops for a half mile along the cliff face. Absolutely no erratic material occurs either within the beds themselves or along the lines of unconformity. The lithologic characters of the lower beds are like those so persistently characteristic of the Cretaceous from Marthas Vineyard to New Jersey; while the upper beds of dark clays appear to be homologues of the Miocene at Gay Head and at Marshfield. This fact, together with the evidence of the unconformi- ties and of the lignites is being examined with a view toward suggesting probable cor- relations with the deposits worked out at Gay Head by Professor Woodworth (Bull. Geol. Soc. Amer., VIII., 1897, 197-212); although the absence of specific paleontologic evidence renders such correlation merely tentative. The detailed descriptions of the beds and the conclusions inferred with respect to their age will be published in a later paper. ” TsatAn Bowman. CAMBRIDGE, MAss. EXOGLOSSUM IN THE DELAWARE. Tue occurrence of the little minnow, Hxo- glossum mazillingua (Le Sueur), in the Dela- ware basin is of interest. So far as I am aware, it has not been taken in any of the tributaries of the Delaware before the capture of two examples which,I caught in the Red Clay Creek, Chester County, Pa., during April of 1904. In this instance I am in- debted to Mr. Alfred ©. Satterthwait, who assisted me in securing the specimens. When [N.S. Von. XXI.

In the Susquehanna basin this fish is abun- dant and I have also met with it in tribu- taries of the Allegheny in Pennsylvania, espe- cially near Cole Grove, in McKean County. Henry W. Fow er.

Proressor Lovén, the Swedish histologist and physiologist who will be best remembered for his discoveries of the endings of the taste- fibers in the papille of the tongue of mammals, as well as of the vaso-dilator nerves, had ex- pressed it as his wish that his brain be pre- served after death and studied by his friend and associate, Gustaf Retzius. With characteristic care and skill Professor Retzius has just published his studies upon Lovén’s brain in Biologische Untersuchungen, Vol. XII., 1905. The brain exhibits a richness of fissures and these are marked by a superior degree of tortuousness and ramification. The subparietal region is very complex in its sur- face configuration, while the central (motor) regions are only moderately developed. The cortical centers for speech and language for- mation are notably large, and Professor Retzius brings this fact into relation with Professor Lovén’s notable powers of clear, ex- act and logical expressions of thought in words; less so in the way of oratorical finesse than in the talented use of the best and most adequate expressions. The weight of the brain is not given in this report though its size is said by Retzius to have been well above the average. Epw. AnTHoNy SPITZKa. APPLES INJURED BY SULPHUR FUMIGATION. RECENTLY some injured Esopus Spitzenburg apples were received at the New York Experi- ment Station with a request to diagnose the trouble. They were of the first grade, each fruit wrapped in paper, and packed in a bushel box. The financial loss was important, as a JuNnr 30, 1905.) considerable amount of high priced fruit had been ruined. Scattered irregularly over the surface of each apple were conspicuous spots of various sizes where the epidermis was dead, discolored and slightly sunken. Each spot was nearly circular, though on some apples the adjacent spots had coalesced, forming a large affected area of irregular shape. Beneath each spot to a depth of a few millimeters, the flesh was dead, shrunken and dry, appearing as though affected with a dry rot. There was no dis- agreeable odor or taste to the dead flesh or epidermis. In the center of each of the smaller spots, and scattered over the larger affected areas, were small bodies resembling the pyenidia of a fungus, but examination showed them to be only the normal lenticels of the apples. Failure to find either fungi or bacteria as a cause of the injury led to the belief that some treatment of the fruit, such as fumigation, might be a cause. Sulphur, being commonly used for fumigation, was experimented with to note the effects of the fumes upon ripe apples. Fruits of different varieties including Esopus Spitzenburg were placed in a bell jar which was then filled with sulphur fumes. After five minutes the fruit was removed and found to have developed numerous spots that were in every way identical with those on the apples received for examination. This experiment was repeated many times with wet and with dry fruits, but the charac- teristic spots were always produced. The spots continued to enlarge for some time after the fruits were removed from the fumes. The presence of a lenticel in the center of each spot would indicate that the sulphur dioxid passes into the fruit at this point and causes the bleaching of the tissue. A similar effect was produced where an artificial break in the epidermis was made. A lenticel makes a strong color contrast with the bleached epi- dermis, thus giving it the appearance of a pyenidium. Sulphur was the only substance used in these experiments; it is possible that other chemicals would produce a similar injury. Geneva, N. Y. Hi. J. Husvace. SCIENCE. 995 THE FLOATING LABORATORY OF MARINE BIOLOGY OF TRINITY COLLEGE. ARTICLES of incorporation have been filed with the secretary of the state of Connecticut ‘to establish and maintain a floating labora- tory of marine biology for exploration in oceanography and the collection and investiga- tion of the organisms of the sea; to supply colleges, museums and other institutions with material for investigation, study and exhibi- tion.’ A vessel of about ninety tons burden will be secured and equipped with the necessary dredges, trawles, tangles, tow-nets, etc., as well as chemical reagents and glassware for work in marine zoology and botany. When the boat is anchored in a protected harbor im- mediately it becomes a laboratory. The vessel, in sailing from place to place in the ocean, will furnish most favorable facilities for the investigation of the distribution and variation of organisms. On each expedition it is planned to stay in some particularly desirable locality for about one month so that problems of eytology, embryology and physiology may be undertaken. Competent preparators, art- ists and photographers will be on the staff so that not only museums and laboratories may be supplied with material, but an effort will be made to meet the specifications of investi- gators as to fixation and preservation, together with sketches, or photographs, of the organ- isms desired for their work. In going to a new region each summer large collections for research will be made year after year and it is hoped to greatly extend our knowledge of the local faunze and flore of the western At- lantic. In the early summer of 1906 the vessel will sail to the Bahamas. After a month in the sub-tropics the boat will weigh anchor for the eruise northward, making a harbor every hun- dred miles or so for the purpose of getting material for comparative studies. In the Bahama Islands the conditions are very fa- vorable for the most abundant and varied organisms since these islands are situated in the mouth of the Gulf Stream where it de- bouches between Florida and Cuba, bringing with it myriads of creatures caught up in the 996 wide cireuit of the current from the equator and through the Gulf of Mexico. The cli- mate, though warm, is agreeable in summer and usually keeps between 84° and 86°. The trade winds blow steadily, the waters are clear and the people honest and simple hearted. Biological investigators have already found the life there in summer both interesting and delightful. These healthful conditions are of great importance for northern men when working hard with both mind and body on the edge of the tropics. While this project centers in Trinity Col- lege, shares have been taken by those inter- ested in other institutions and it is in the largest way for the benefit of all investigators who care to take advantage of the opportuni- ties offered. CuHarues L. Epwarps. FEDERICO DELPINO. By the death, at the age of seventy-two, of Professor Federico Delpino, of the University of Naples, modern botany has lost one of its pioneers. For, according to Friedrich Lud- wig, a leading authority on the subject, the foundations of plant biology were laid by the publication in 1867 of Delpino’s ‘ Thoughts on Vegetable Biology, on Taxonomy and on the Taxonomic Value of Biological Characters.’ Born at Chiavari, in the province of Genoa, his childhood was largely passed in the garden of his father’s house, where he studied closely the habits of ants, bees and wasps and suc- ceeded in discovering the mode in which the great blue-black bee, Xylocopa violacea, con- structs its nests. His education was the classical one usually given to an Italian boy of that day, and his employment for nearly ten subsequent years was in the routine of the custom house. About 1864 a friend called Delpino’s atten- tion to the account of an English observer of the manner in which a Ligurian orchid was pollinated by Xylocopa. Delpino at once re- plied to his friend that there should be a similar apparatus in the flowers of the As- clepiadacee and he hastened to Chiavari to verify this prophecy. Here he quickly found the Xylocopa in the act of pollinating the flowers of a magnificent Brazilian asclepiad. SCIENCE. [N.S. Vou. XXT. No. 548. The discovery of the relation between this plant and its insect visitor was a turning point in Delpino’s career, for the paper which he promptly published at once put him into rela- tions with the botanical world and marked the beginning of a long series of brilliant re- searches. Becoming a professional botanist, Delpino taught successively in the universities of Genoa, of Bologna and of Naples. His predominant interest was always in the relations between plants and animals, but he made valuable researches and thought pro- foundly on other departments of botany, at- tacking problems as far away from his chosen subject as phyllotaxy and plant geography. As a university professor Delpino was prob- ably more feared than loved by his students. No member of the first class which took the final examination in botany at the University of Naples after Delpino’s assumption of the instruction in that department will ever for- get the wholesale manner in which the failures were recorded. His manner, too, would im- press one who met him for the first time as somewhat ascetic. But an experience of al- most ten years, of the unvarying courtesy with which Pr’}-:ssur Delpino, in frail health and loaded wit arches of his own, would re- spond to every demand for an opinion leads the writer to remember him as no less typical an Italian gentleman than he was an ideal scholar. J. Y. BERGEN. NAPLES, May 26, 1905. THE AMERICAN MICROSCOPICAL SOCIETY. Tue twenty-seventh annual meeting of the American Microscopical Society will be held at Cedar Point (Sandusky), Ohio, on July 5, 6, 7 and 8, 1905. The society will be the guest of the Ohio Lake Laboratory under the direction of Professor Herbert Osborn of Ohio State University who has placed at the dis- posal of the meeting all the facilities of the laboratory and who is planning excursions and collecting trips to demonstrate the rich fauna and flora of this region. The meetings will be held in the laboratory with the exception of the president’s address which will be given in Sandusky. JUNE 30, 1905.] The general outline of the program shows that Wednesday morning is devoted to busi- ness, the afternoon to the reading of papers and the evening to the address of the retiring president, Dr. Henry B. Ward, on ‘The Re- lations of Animals to Disease.’ Thursday’s program is especially devoted to medical zool- ogy, the morning being given to papers and the afternoon to a symposium, led by the presi- dent, on animal parasites, their effects on the hosts, with demonstrations of specimens and microphotographs, and discussion. This even- ing the society will be tendered a reception. Friday the program includes papers and a symposium on fresh water biology, led by Dr. R. H. Wolcott, covering the field of limnobiol- ogy. The evening will be spent on the beach and Saturday will be devoted to excursions. Summer tourist rates make Sandusky an easy place to reach from all points, and the new hotel, ‘The Breakers,’ which has been selected as headquarters, insures satisfactory accom- modations. There will be at the meeting demonstrations of apparatus and specimens both by firms and individuals. Persons haying specimens or photomicrographs of parasites and other forms which they may wish to show can send them to headquarters in care of the officers and they will be duly presented and returned at the close of the meeting. COLUMBIA UNIVERSITY AND DR. R. S. WOODWARD. Ar its recent commencement exercises, Co- lumbia University conferred the degree of doctor of science on Dr. R. S. Woodward, formerly professor of mechanics and mathe- matical physics, and now president of the Carnegie Institution of Washington. He was presented by Professor Edmund B. Wilson, head of the department of zoology and Dr. Woodward’s successor as dean of the faculty of pure science, who said: “It is a rare dis- tinction to have attained a position of com- manding eminence at once in scientific dis- covery, in scientific teaching, and in the direc- tion of scientific and educational affairs. It is my privilege to present for the honorary degree of doctor of science one whose many- sided achievement has written his name high SCIENCE. 997 on the rolls of fame for all of these—Robert Simpson Woodward, for many years the hon- ored and beloved dean of the faculty of pure science, and now president of the Carnegie Institution of Washington. In a distin- guished service of more than twenty years under the national government, as engineer of the lake survey, astronomer and chief geographer of the Geological Survey and as- sistant on the Coast and Geodetic Survey, his varied and profound researches won for him a secure place in the front rank of those who have successfully grappled with the great problems of astronomy and geophysics. For twelve years a professor at Columbia, his work as teacher and investigator in the fields of mechanics and mathematical physics has of- fered a model of lofty ideals and exacting standards to his fellow students, whether those whom he taught or those who taught with him. As dean of the faculty of pure science he has served Columbia with a conspicuous devotion, loyalty and success that will not be forgotten. His has been the leadership not alone of the eminent scholar and wise counselor, but of the trusted friend, and his example has taught once again the lesson, greater than any in his own large and difficult field of scholarship, that the cause of learning may be advanced as much by the quality of the man as by the achievement of the man of science. As presi- dent of the New York Academy of Sciences, of the American Mathematical Society and of the American Association for the Advance- ment of Science, he has been the far-seeing and eloquent spokesman of science to his fel- lows. He has now been called to a place of leadership in organized scientific inquiry for which history can not show a parallel. Co- lumbia bids him godspeed, and gladly pays her tribute of honor to one whose life and work have been an honor to her.” SCIENTIFIC NOTES AND NEWS. Tue American Chemical Society met last week at Buffalo under the presidency of Francis C. Venable, of the University of North Carolina.

JOURNAL OF PEDAGOGY ESTABLISHED IN _ 1887 An Educational Magazine of interest to all serious students of education. Some of the ablest contributions now being made to educational literature are appearing in the JourNnaL oF PEpacocy. A REPRESENTATIVE OPINION “Tn building up the occupation ot teaching till it becomes a true profession, no magazine is rendering more significant and vital service than the JOURNAL oF PEDAGOGY, which admirably displays the interest of the editor in the science and art of education. Its articles have always been noteworthy for their strength and freshness; its book reviews have been conspicuously valuable, exceeding in number those of the several other leading magazines combined. No field of educational effort has been neglected ; and there has been a reason- able apportionment of space alike to the university, the high school, the elementary school, and the kindergarten. Those who are earnest for the better- ment of American education view with the greatest seriousness the endeavor of such a magazine as the JOURNAL OF PEDAGOGY to represent the best thought and practice of the times, and by representing that thought and practice to encourage their influence. To publish such a periodical is a noble PE ng for the welfare of American schools and of the American nation.’’—Dr. W. Chancellor, Superintendent of Schools, Paterson, N. J.
