GORDON ACADEMY OF NATURAL SCIENCES OF PHILADELPHIA, APRIL 15, 1922 THE AMERICAN CHEMICAL SOCIETY (Continued) SECTION OF CHEMICAL EDUCATION Edgar F. Smith, chairman Neil E. Gordon, secretary First year college chemistry: Witu1amM Mc- PHERSON. A first course in general chemistry: WILHELM Srcerstom. A brief comparison is made of four- teen of the more modern texts in chemistry suit- able for secondary schools. The results of a re- cent text-book survey made by the New England Association of Chemistry Teachers are given. The usual custom of starting beginners in chem- Juny 14, 1922] istry on gases and gas laws is eriticized. The belief that the ordinary student can get more tangible results by starting with more tangible substances is put forth. A scheme of experimen- tation, which was tried out at Exeter some years ago, and which starts the student on some common metals and leads up through a series of ninety experiments to a little chemical investigation of an unknown substance without the use of a con- ception of atoms, molecules and symbols, is de- scribed. The scheme was satisfactory from the point of view of teaching chemistry but had its limitations for those who must primarily prepare students for the college entrance examinations. A possible revision of the College Entrance Exam- ination Board syllabus is suggested. First year chemistry for women: Minnir B. FisHer. Women students who take chemistry as a cultural subject, or as a prerequisite to home economics courses, should be taught in separate groups. They lack background for scientific work, will devote little time to pure science and need very careful laboratory direction and super- vision. Conference periods should be arranged to clear up difficult points. The utmost accuracy in observation and recording of facts should be insisted on. Greatest cultural value is to instill into students greater respect for truth. Greater proportion of time should be devoted to study of chemical history, theory and non-metallic ele- ments. Metric system: EUGENE C. BINGHAM. Metric education has been too largely neglected in the elementary schools, so we need not only to instruct our students in its use, but also in the desira- bility of an extension of the use of the metric system. Particularly we should give an object lesson to students by buying apparatus and chem- icals and selling it in metric quantities. Methods for presenting first year chemistry: F, P. VENABLE. The project method of teaching chemistry: Nei E. Gorpon. items as representing different funda- mental ideas to be kept in mind in planning for two different things in the same laboratory. In the matter of locks for desks in the freshman laboratory the fundamental idea is to save time. Getting into a desk is wholly a matter of routine; hence a time saver is worth while. Therefore compare the time involved with different locks and, as a secondary matter, expense and trouble to the institution. In the matter of reagent bottles it has got into the minds of some that time saving is the fundamental principle. Not so, they are teachers. The time of students spent in look- ing at reagent bottles is well spent; therefore the bottles should be where they can be seen. The fundamental principle is to have excellent reagent bottles where they hold the attention of the stu- dent. A comparison is then made of varieties of locks and of reagent bottles. A chart of the synthetic intermediates: CHAS. W. Cuno. A chart of the various commercial intermediates prepared from the distillates of coal tar, their type syntheses, the relation of these intermediates to one another, and their relation- ship to the common dyes of commerce. Three objects are in view: (1) to give the student in organic chemistry a bird’s-eye view of this im- mense field; (2) to aid the manufacturer and commercial chemist in understanding and covering his field; (3) to show the research chemist possi- ble gaps in present syntheses. Training for agricultural chemistry: W. F. HAnp. [ Vou. LVI, No. 1437 Unified chemistry courses: Jack P. Monr- GOMERY. Standard tests in science, especially chemistry: H. A. Wess. Standard tests have become adopted as a definite method in educational practice. A standard test may be defined as a method of measuring quantitatively a pupil’s intelligence or his achievements in a certain branch of study. Various workers in the field of science as early as 1917 began to publish proposed standard tests in different scientific branches. The different types of tests and methods suggested up to the present time were illustrated. It is proposed by some that a type of quick, rapidly taken test be substituted for the conventional two or three hour examination which is so frequently used. The results obtained with such tests were discussed, and the advantages and disadvantages set forth. The use of standard tests in science has not been widely adopted, for none of them are standardized in the ordinarily accepted sense of the word, the whole matter being in a very experimental stage. Science or athletics? HE. G. Mauin. The steady increase in extra-curricular activities in our col- leges is believed to be largely responsible for the much discussed decline in our standards of scien- tific education. It is believed also that the ab- normal development of commercialized intercolle- giate athletics is the greatest obstacle to restric- tion of such activities to sane and reasonable limits. In this paper it is argued that our stand- ards can not be materially improved until the col- leges divorce themselves from commercialized ath- letics, and that this necessarily involves elimina- tion of the high salaried professional coach and correction of the disproportion now existing in expenditures for athletics and for educational purposes. : SECTION OF HisToRY OF CHEMISTRY C.

Altogether 36 elements and 144 compounds are listed on which computations may be based. The calculation is carried out by means of sliding por- tion, as in the ordinary slide rule, the slider being subdivided into divisions representing the log- arithmie ratios of the numbers from 8 to 330. The ‘equivalent weights’’ as given and the nomen- clature are interesting from the historical stand- point. Reminiscences of Italian McPHERSON.

Quite a number of autograph letters, pam- phlets, pictures and books were shown and some pieces of apparatus. chemists: WILLIAM DIVISION OF ORGANIC CHEMISTRY H. T. Clarke, chairman Frank C. Whitmore, secretary The preparation of methylmercuric acetate and methylmercuric hydroxide: M. C. SNEED and J. Louis Maynarp. During the course of an investigation of the thermal decomposition of mercurous acetate in an atmosphere of nitrogen, the formation of a small quantity of an organic derivative of mercury was noted. This product was assumed to be methyl mercuric acetate, despite the fact that its properties did not agree with those described by Otto. Doubt was cast on the purity of his salt prepared by the action of acetic acid on mercury dimethyl at 120°. Jones and Werner have shown that, at higher tempera- tures, a more complicated reaction takes place with no evidence of the formation of the desired salt. The true methylmereurie acetate has been prepared by four reactions, each of a different type, none of which admits the possibility of the decomposition of the desired organomercuric salt. SCIENCE 53 These methods were: (1) Action of mercuric acetate with mercury dimethyl; (2) Action of methylmereurie iodide and silver acetate; (3) Neutralization of methylmercuric hydroxide with acetic acid; (4) Action of methylmereurie hy- droxide with ethyl acetate. The same organo- mereurie salt was formed in each of the above reactions. It was identical with the mercury derivative produced in the decomposition of mer- eurous acetate. The hitherto unprepared methyl- mercuric hydroxide required in methods 3 and 4 was obtained as a white crystalline solid by the action of moist silver oxide on methylmercuri¢ iodide. An electrolytic method for the preparation of mercury dimethyl: Henry C. Howarp, Jr., and J. Louis Maynarp. Although mercury dimethyl has been obtained by Kraus by the electrolysis of aqueous solutions of methylmercurie salts, the low conductivity of such solutions renders the process unsuitable as a means of preparation of the dialykyl. However, it has been found that the addition of pyridine in approximately equi- molecular quantities increases the conductivity to such an extent that electrolysis becomes a satis- factory method of preparation. In the course of this investigation the conductivities of solutions of methylmereuric hydroxide and several of its salts were determined. It is interesting to note that these measurements show methyl mercuric hy- droxide to be an extremely weak base. This is contrary to the statements in the literature. The asymmetry of diazodiethylglutamate: W1L- tiAM A. Noyes and H. M. Cuites. While Noyes and Marvel did not succeed in obtaining optically active diazo esters in which the asymmetry was due to the carbon atom to which the diazo group is attached, Levene and Mikesha have reported the preparation of such a compound from 1/-diethyl aspartate. We have obtained an active diazo ester, EtO,C-CH,-CH,-CN,-CO Et, from d-diethy]l glutamate ‘by the Curtius method. The carefully purified ester is a yellow oil which boils 92-93° under a pressure of 0.1 mm. Other optically active substances which might have been present were carefully removed and the composition was established by analysis. The specific rotation at 20° for the D line is +1.68°. The specific rota- tion in a 10 per cent. ether solution is +4.03°. The diazo ester, in solution in ether, gives the d-hydroxy ester on shaking with NH,SO,. Sapon- ification of the hydroxy ester gives the sodium salt of a hydroxy acid which is also dextro- rotatory. It is difficult to reconcile the optical 54 SCIENCE activity of this diazo compound with the Lewis- Langmuir theory of the combination of atoms in “‘non-polar’’ compounds. Further observations on the nitration of halo- genated phenols: lL. CHas. RatrorpD and LIANG Yr Ho. Previous work by Raiford and Heyl has shown that the method of nitration of brominated phenols first used by Zincke is suitable for the bromine and iodine compounds, but that the nitro radical fails to replace chlorine; and that, fur- ther, both dibrominated and tribrominated deriva- tives of ortho and meta eresols may be expected to give isomeric nitro derivatives. The small yield (10-12 per cent.) of the para siomeride, 3-bromo-5-nitro-o-eresol, obtained when dibromo- o-eresol was nitrated in this way raised the ques- tion as to whether the position taken by the nitro radical depends more upon the relative position of the halogen atom or upon its character. To get data on this point, 3-chloro-5-bromo-o-cresol and its isomer, 3-bromo-5-chloro-o-cresol, were nitrated. In each case the bromine was displaced, giving the isomeric compounds, 3-chloro-5-nitro-o- eresol and 3-nitro-5-chloro-o-eresol. New organic selenium compounds: Marston Taytor Bogert and Y. G. CHEN. By the action of hydrogen selenide upon acyl anthranilic nitriles, selenoquinazolones have been prepared and studied. Derivatives of 2-phenyl benzselenazole also have been investigated and show some inter- esting properties. The synthesis of a thiazole analog of cinchophen (atphan): Marston Taytor Bogert and EE. ABRAHAMSON. 2-phenyl benzothiazole is nitrated, giving the 6-nitro derivative, which is reduced to the amine, and the latter is then changed to the corresponding carboxyl compound through the diazo reaction. Various derivatives and collateral compounds were prepared. The position of the nitro group was proved by decomposition of the amine and by its conversion to the- benzobis thiazole. Hydrocyanice acid: an ammono carbonous acid and an emmono formaldehyde: EDWARD C. FRANK- LIN. From a purely formal point of view HNC represents hydrocyanie acid as an ammono ear- bonous acid, while the nitrile formula represents it simultaneously as an ammono formaldehyde and as formic ammonid. Sodium ammono carbonite may be nitridized to an ammono carbonate by a considerable number of methods, as, for example, by the action of sodium ammono nitrate and of cyanogen as _ represented~ by the equations, NaNC + NaNa = NCNNa, + N; and [Vou. LVI, No. 1437 NaNC + CN, = NaN(CN), + C. As an am- mono aldehyde, hydrocyanie acid undergoes poly- merization and condensation, forms addition com- pounds with bisulfites, ammonia, water and alco- hol, reacts with hydroxylamine, hydrazine and phenylhydrazine, and is reducible to an ammono alcohol. A study of the optimum condition for the formation of the Grignard reagent: HENRY GIL- MAN and CHas. H. Meyers. Two satisfactory methods for the estimation of the Grignard re- agent are being used. One involves titration with standard acid and the other the measurement of gas evolved when the reagent is decomposed by water. The study concerns those ordinary factors affecting the yield: rate of addition of RX, con- centration of reagents, kind of magnesium, cool- ing during formation, refluxing after formation, stirring, kind of air protection (calcium chloride, soda lime, ete.), catalysts, etc. This preliminary report is on ethyl magnesium iodide. The reaction between thionyl aniline and the Grignard reagent: HENRY GILMAN and Harry L. Morris. In connection with a series of studies on the mode of reaction of the Grignard reagent with compounds having more than one reactive grouping, thionyl aniline (C,H _N=S=O) has been treated with several RMgX compounds. Phenyl magnesium bromide gives a good yield of the anilide of benezen sulfinie acid. Excess of the Grignard reagent gives the same compound. Up to the present no success has attended attempts to determine the mechanism of the reaction—the —MgX may have added either to the nitrogen or to the oxygen. Arsenated heterocyclic compounds prepared from 3,4-diaminophenyl arsonic acid (amino arsanilic acid): W. LEE Lrwis and R. 8. Buy. The great reactivity of the ortho-diamines with a great variety of substances yielding quinoxalines, azimides, piafthioles, imidazoles, etc., suggested the easily available amino arsanilic acid as a fruitful starting point for new organic arsenicals. 3,4-diaminophenyl arsonie acid is made by nitra- ting oxalyl p-arsanilie acid and reducing the nitro compound with ferrous chloride and ammonia. Thus far this compound has been condensed with benzil, oxalie acid, pyruvic acid, maltosone yield- ing the following: 2,3-diphenyl-quinoxaline-6- arsonie acid, 2, 3-diketoquinoxaline-6-arsonic acid, 2-methyl-3-hydroxy-quinoxaline-6-arsonic acid, and 3-(glucosido-erythrityl) -quinoxaline-6-arsonic acid. Derivatives of the beta-chloro-vinyl arsines: W. Lee Lewis and H. W. Stizcuer. The chloro- Juny 14, 1922] vinyl arsines were prepared by the action of acetylene upon arsenic chloride in the presence of aluminum chloride and were separated by frac- tionation under reduced pressure. The following derivatives were prepared: Beta-chloro-vinyl arse- nious oxide, beta-chloro-vinyl arsonic acid, beta- chloro-vinyl di-iodo arsine, beta-chloro-vinyl bi- bromo arsine, hydrated bis-beta-chloro-vinyl ar- senie acid, bis-beta-chloro-vinyl arsenious sulfide and bis-beta-chloro-vinyl arsenious oxide. Chemical and crystallographic notes on the acid phthalates: FRANcIs D. Dopez. The use of potas- sium acid phthalate as ultimate standard in alka- limetry was suggested by the writer in 1915. This salt and the corresponding salts of sodium, am- monium, lithium and magnesium have since been more carefully examined. Acid salts of the formula, 2MHC.H,O,.C,H.0O, (M = K, NH), were also observed. The acid phthalates erystal- lize remarkably well, and invited further study. The potassium, sodium, ammonium and lithium salts have been measured. The potassium and ammonium salts are isomorphous, and also show an interesting isomorphism with the corresponding salts of ortho-sulfo-benzoic acid. The rubidium and cesium salts were also prepared, and appear to belong to the same isomorphous group. In optical properties, the crystals of the potassium and lithium acid phthalates proved interesting, as they exhibit crossed axial plane dispersion toward the violet end of the spectrum. The same variety of dispersion is also very well shown by the mixed erystals of potassium and rubidium acid phthal- ates. The occurrence of formic acid in essential oils: Francis D.

R. Ramsey, Indiana University, Bloomington, Indiana The atom consists essentially of a coil with an iron core mounted vertically, above which is a tray with electrodes so placed that when current is sent through mercury placed within the tray, the current fiows radially toward or away from the center. This produces a magnetic field and a current at right angles and consequently there will be motion in the third direc- tion and the mercury will rotate. The tray is connected to a storage battery. A carbon rheostat may be inserted in circuit to vary the current and it is advisable to have an ammeter to measure the current. The current should be from 2 to 5 amperes. The coil is best operated by connecting to a 110 volt lighting circuit with a bank of lamps for resistance and the ammeter may be inserted for measuring the current. This current should take from 2 to 5 amperes also. The amount of current necessary will depend on the adjustments and should be varied so as to get the best operative conditions. Two balls placed on the rotating surface alternately rotate in elliptical orbits about each other. Three balls rotate in ellipses about each other but the motion is more complicated and more difficult to follow. A larger number of balls form a ring which rotates as a fixed, stable form. Various stable forms such as a ring with one or more balls in the center, or one or more rings may be formed. Other phenomena such as the breaking apart of a stable form by means of concentrating the lines of force through a ring outside and the illustration of radioactive matter, etc., may be shown. A booklet of instructions describing the apparatus in detail and many atomic phenomena that may be illustrated, will be sent upon request. Bulletins of other apparatus recently developed and illustrating some of the more recent developments of science will be sent upon request. A SIGN OF QUALITY \WWIBILC]H] A MARK OF SERVICE / W. M.

Any account of the geology of the Colorado River basin falls naturally into two parts: that which deals with the life of the Colorado River and that which deseribes the preceding ages before the river began to flow. Professor Pack has presented the life history of the river. It is my task. to sketch the earlier history of this part of the continent. With reference to the engineering problems, the geologist is con- cerned with three questions. relating to the sta- bility of the dam as affected by, possible earth- quakes, the nature of the foundation rocks, and the durability of the rocks used in construction. Reference will be made to these matters after the geology has been described. We have become familiar with moving pic- tures, which present a succession of views, each one of which differs so slightly from the pre- ceding that the eye sees their sequence as a con- tinuous movement. The intervals are fractions of a second. The action is timed to our human scale. Geographic changes are exceeding slow. If we would present a moving picture of a succession of landscapes, the intervals between the views would be a hundred thousand or even a million years. Even so, the eye would see a continuous procession of views. Mountains would grow to majestic heights and waste away till their sites became plains. Rivers would develop and competing for territory would be- come master streams or tributaries according to the law of the strongest. Seas would invade the land ‘and retreat from it after ages of occu- pation. Climates, floras and faunas would change. Such is the moving picture of geologie 1 Presented in the Symposium on ‘‘The Prob- lems of the Colorado River’’ at the Salt Lake City meeting of the American Association for the Advancement of Science and the Pacifie Division. 178 history. Even that slow movement of events is be- yond our power to present in its continuity. We can at best represent widely separated con- ditions. And so, in attempting to sketch the history of the Colorado Plateau region, I can give you detached pictures only, some of them so unhke that imagination alone can link them together. It will be simplest to roll the broken film backward from the later, better known events to the earlier scenes, till knowledge be- comes guess and guess fades into surmise in the mists of antiquity. The Colorado River developed during a period before the present plateaus were ele- vated. So great a river system, like a great empire, is the result of many territorial con- quests. The force by which it conquers is due to its fall, for by its fall it carves its canyons and extends its tributaries. Thus the earlier history of the river corresponded with an earler ancient uplift of the plateau country. But that uplifted mass was first gashed by canyons, then became a land of broad valleys and mesas, and finally was eroded to a low plain. A later uplift has raised that plain to its present position, 7,000 feet above the sea, where it is the surface of the plateau. The cycle of erosion just referred to is called the “Great Denudation.” The time of its dura- tion corresponded with the so-called early Ter- tiary. The early mammals drank from the growing Colorado. North America then, as now, stretched from the Atlantic to the Pacific, an undivided continent. Stepping back a million years or so, we see North America divided. A broad, though shallow, strait stretched from the Gulf of Mexico to the Arctie Ocean along the Great Plains of to-day, dividing the continent into an eastern and a western land. The climate was mild and equable. Vegetation flourished in the warm humid atmosphere. It was the Coal period of Colorado and New Mexico. Great saurians dominated the life of the period, yet became extinct, apparently rapidly. Dull brutes, they were incapable of adaptation to changes of environment such as closed the period of their dynasty. During this period, the so-called Cretaceous, the region of the Colorado plateaus was a SCIENCE It is timed to the march of the ages. | [Vou. LVI, No. 1442 watered land with rivers flowing from eastern coast ranges, on the site of the Rocky Moun- tains, toward the Pacific. Among them may have been the stream which eventually grew to the Colorado, but we can not identify it. Still retreating down the aisles of time, we come upon the panorama of a wide North America, united from east to west, but sub- merged along the western margin even to Idaho. This, the Triassic and Permian periods of geologists, might well be called the period of the “Great American Desert.” A red wind- swept delta plain covered the Rocky Mountain states from Montana to Arizona and extended southeastward over Oklahoma and _ Texas. Bleak and arid, it was like the plains of north- ern Siberia. Similar cold, barren lands existed widely throughout the continents. It was a time of stress for all living things and led to the evolution of higher forms than had pre- viously existed when conditions bettered, just as the severe environment of life during the Glacial Period later led to the evolution of man from his ape-like ancestors. The red muds and sands of the desert time reached far into the Colorado Plateau country and, in so far as they were not eroded during the “Great Denudation,” they give the dom- inant color note to the upper gorges of the river. Thus far in our retrospect we have found no epoch during which the plateau country was submerged beneath sea waters. Yet there is written in the strata of the canyon walls a very long record of marine conditions. Whoever has been down the Bright Angel Trail has seen it. The cliffs of sandstone shale and limestone demonstrate by their long horizontal lines of bedding, as well as by the fossils they contain, that they were laid down beneath the sea. It was never a deep sea, yet there gath- ered in the basin more than 4,000 feet of strata. Evidently the bottom sank gradually and the sediments gathered as the basin deepened. Far more impressive evidence of subsidence is found near Salt Lake. There the strata ag- gregate more than 40,000 feet in thickness and indicate a corresponding subsidence of the an- cient foundation rocks. It is clear from the great difference between 4,000 and 40,000 feet that we should not re- Aueust 18, 1922] gard the subsidence as uniform. On the con- trary, it was an unequal warping of the sur- face, which indeed rose and remained land in the region southeast of the canyon, or was but temporarily submerged. The invasion of the sea into western North America began with and extended through the so-called Paleozoic age, that vast lapse of time during which life evolved from the grasping crustacean to the ambitious reptile. It is one of the proofs of evolution that although the Paleozoic creatures are long since extinct, their mentalities still persist in individual men. Ac- cording to geologists the Paleozoic was an era which began with the Cambrian period and closed with the Permian. Various intervening periods are distinguished, but for our study of the Colorado River basin, the Paleozoic stands for one event, the advance of ocean waters over much of the continent, their prolonged occu- pation of its area accompanied by numerous changes of front, and their retreat into the permanent ocean basins. Back to the beginning of the Paleozoic era, including the Cambrian period, we have fairly complete records of the physical geography of the earth and we can trace the major lines of evolution of organic life. We can even attempt maps of the shifting lands and seas, follow the course of great climatic oscillations, and image in our minds the habitats in which our remoter and nearer ancestors lived. If we draw a parallel between human history and earth history we may compare the dawn of Assyria with the beginning of the Paleozoic. But the remoteness of Assyria is to be measured only in hundreds, whereas that of the early Paleo- zoie is to be estimated in as many millions of years. Let us not think, however, that a hundred million years represents a large proportion of the earth’s history, as it is recorded in the rocks of the Grand Canyon. Beneath the earliest Paleozoic strata lie other water laid deposits of sediment, the waste of ancient lands. Only a few fragments of those old records are known, but they testify unmis- takably to the passage of unnumbered ages. We are prone to think the earth must have been in a different state of cooling or had a different atmosphere in so distant a past. But SCIENCE 179 no, the winds blew, rains fell, streams flowed, there was night and day, heat and cold. And within the earth there went on periodically those changes which occasion the rise and sub- sidence of continents, the growth of mountain chains. The Algonkian strata (such is the name geologists use to designate the era) were deeply buried, tilted up, invaded by masses of molten rock and eroded. They record activities identical in kind and intensity with those which are now active in the most youthful ranges, the Rocky Mountains and the Sierra Nevada. Though we look back two hundred million years we find earth-processes the same. Hiven so we have not read the earliest chapter recorded in the rocks of the Grand Canyon. Beneath the Algonkian we come upon an older and different group of rocks. It is a group which never occurs anywhere but at the bottom. It is the foundation of the superficial crust. I speak of the so-called Archean, the oldest rocks known, though by no means necessarily the oldest rocks ever formed. The Archean rocks are not surface rocks, not like the strata of the plateau country. They have risen from depths in the earth’s crust where temperatures are high and _pres- sures are enormous. The typical Archean are crystalline. Whatever the previous state of the minerals may have been, they have re- crystallized. Some, which are called schists, have reerystallized in a solid state under over- whelming and unequal pressures. They have thus changed form, shortening anad lengthen- ing to fit their Procrustean bed. Others, the granites, have been melted and have intruded as tongues of magma into surrounding masses, causing changes of crystalline form in them. Melting and recrystallizing, erystallizing and remelting, these rocks have undergone changes so complete that no one can tell what they may once have been nor through what sequence of kneading, mechanical shearing, folding, and chemical changes they may have passed. The Archean rocks thus represent physical and chemical conditions which exist within the earth’s outer shell. I say advisedly exist, not exisied. For while it is true that we see only very ancient rocks of this character, there is every reason to assume that they are forming now beneath our feet. We know that the 180 earth, though solid, is very hot. We know that very great and unequal pressures exist at depths of a few miles beneath the surface. These are the conditions under which the Archean rocks formed and no doubt are forming. In the laboratory of the Master no reaction oceurs except according to law, and law is eternal, unchanging. ‘There is, perhaps, no thought with which we may more appropriately approach the engineering problems of the Colorado River. The engineers who will speak here of the utilization of the Colorado will describe works of great magnitude: dams surpassing any yet built; reservoirs impounding millions of acre feet of water; values of irrigated lands rising to hundreds of millions of dollars; powers which are to turn the wheels of industry from San Francisco and Los Angeles to Denver. But even so, they speak only as men, of the little works of men. In the laboratory of the Master their greatest accomplishment is infi- nitely small and transient. A laboratory is a place where the forces of nature work changes in material compounds or erystal forms according to law. The me- chanic, the physicist, the chemist arranges the conditions of some desired reaction and under the same conditions observes the identical effects recurring endlessly, unfailingly. If he makes an experiment the personality of the ex- perimenter makes no difference. Even the Master works by law and can not work other- wise. Nor does time make any difference. A billion years ago the law of gravitation held the stars to their courses as it does to-day. In the earliest conceivable eon of the existence of matter the atoms moved to their places in molecules in the same order as now. Yet there is a new development, no doubt also in obedience to law, but so subtle that we can not establish the relation. I mean the evo- lution of mind, which can investigate law, which can conceive and execute great works that rightly constructed will stand for ages. The mind can even trace its own evolution. Backward from human thought to animal instinct, from instinct to mere conscious ex- istence, from consciousness to unconscious molecular reaction runs the chain. It runs un- SCIENCE [Vou. LVI, No. 1442 broken. Life is its characteristic. But if thought is life, then is consciousness also; if consciousness is life, then is molecular reaction also life. In this sense minerals are alive, for they are chemical compounds which react to their environment. The earth is alive, for the reactions of its masses are evidenced in un- ending change. The development of thought from uncon- scious reaction has recently evolved reason. Reason is so young, however, that it is still embryoni¢e and in many humans is in a larval state. Nevertheless, no man becomes a scien- tist or engineer without having to some degree developed it and therein lies the hope of a successful solution of the extraordinary prob- lems of the utilization of the Colorado. The major difficulty in damming the Col- orado is to establish the dam on a firm founda- tion. Investigations of the river’s bed show that it is filled to depths exceeding a hundred feet with large boulders. The dam, if it be a masonry or concrete structure, must be welded to the solid rock in place. It will tax the re- sources of the engineer to the utmost to dig so deep through boulders and to place his foun- dation structure during the few months be- tween floods, which, if unrestrained, will destroy it. . The presence of a boulder bed, of such depth and composed of rocks of such size, was not foreseen. It is due to the power of the floods. At low water the river ripples impotently around the stones. One can hardly conceive that in flood it moves rocks as large as cabins and buoys up a mass of them, rolling them over one another with irresistible foree. But the evidence is there. It does. The bottom of the river in flood is a torrent of rolling rocks, of huge size. They roll, they jam, they tem- porarily resist. The river piles up its waters behind them. The rocks yield and are carried crashing down the channel to come to rest as the victorious waters roll on. It is one of the most daring conceptions of modern engineering that this awful power may be used to build the dam that shall chain it. How, may best be stated in speaking of the types of dams that are under consideration. The engineer and geologist are both cog- nizant of the power of floods. But there are Aveust 18, 1922] some facts regarding the structure of rocks which lie more exclusively in the province of geology. The first of these is what is called ‘Jointing’ in rocks. Jointing is a mechanical effect. It is produced by pressure in the case of massive rocks, like granite, or by torsion in the case of strata, when they are warped. All the rocks of the plateau region are jointed. In the magnificent architecture of the Grand Can- yon, the vertical cliffs are the planes of joints. In the pointed forms which are characteristic of the deepest gorges in the granite, we see the effect of two or more intersecting joint planes. Now joints permit water to penetrate under and around a block of rock. The film of water may be very thin, but to the extent that it sur- rounds the rock it buoys it up, tends to lift it from its bed by virtue of hydrostatic pressure, and may free it from its firm foundations. Engineers are fully aware of this action. They seek to excavate to foundation rocks which show no open joints, or to seal visible joints by cement. Granite is regarded as one of the firmest foundations. It is liable, however, to blind joints, invisible planes on which there has been no actual parting, but the minerals have been strained and are ready to react to forces of decay. Water, not enough to wet, but just enough to moisten, is the agent that sets those forces to work. The engineer can not discover blind joints. Investigation of the minerals by the microscope, a study which is among the most specialized of geologic train- ing, alone can demonstrate whether or not they are present. We may think that the invisible is reason- ably negligible. But the infinitely small is the infinitely powerful and also the infinitely pa- tient. A film of water penetrating a plane of strained crystals may open the way to the ulti- mate destruction of man’s mightiest work. Minerals decay. That is not a familiar thought with many, although soil, a product of mineral decay, is familiar to every one. I said that minerals are alive. And it is because they are alive that they decay, decay being simply the reaction to a change of environment. Evi- dence of these facts is found in the rocks which the engineer must use in building a dam in ihe Canyon of the Colorado. A : 7 The granites and SCIENCE 181 schists of the ancient formations crystallized deep within the crust in an environment of very high temperature and great pressure. Hlevated to their present positions at the sur- face they are in a cool environment, under little pressure. The change produced in every erystal a tendency to change, to disintegrate into forms and compounds better suited to their actual environment. Thus the seemingly solid granite of the Boulder Canyon site is pervaded with disintegrating forces, which will in the course of time, though probably long time, certainly cause it to crumble. Let us now consider the two methods of building the proposed dam, which have been suggested. The first fascinates by its unusual character and its daring. It consists in blow- ing great masses of rock from the canyon walls into the river channel in such quantity that they will form the body of a dam three quar- ters of a mile up and down stream on the base and six hundred feet high. The blasting is not to be done all at once, but in sections from upstream downward and only to a part of the height at any one time. And the river is to be allowed to flow over the fallen rock masses in such manner that it will by its own power dig the deep hollows into which it shall also roll the great rocks. Thus the river shall work its will, but shall lay the masses where it can never move them again. It shall chain itself. The success of this operation depends upon providing by blasting rock masses of such magnitude that the river can not carry them away. We have a report by Mr. Ransome, a geologist of the U. 8. Geological Survey and one of the highest rank, to the effect that the granite of Boulder Canyon is considerably jointed. Conservative knowledge would sug- gest that there are many more joints than ap- pear as actual fissures and that they would cause the granite to break into relatively small masses, in the blasting from the cliffs and sub- sequent rolling by the river. Another question is how “solid” is the granite? That it is so described is natural, for “granite” and “solid” are almost synony- mous terms to English speaking peoples. The significance of words depends upon our asso- ejation with them and our experience of New 182 England granite says that it is the very symbol of solidity. But New England granites have been stripped by glaciers of every trace of de- cayed rock. They are solid because they are freshly exposed. That is not the ease with granites in this western country. For instance there is granite in the imme- diate vicinity of Salt Lake City. It seems solid. It is used in building. It will take a polish. But I am told it will not hold a polish more than three or four years, because the crystals have begun to decay. Professor Pack tells me that he has examined granite in this vicinity from the surface to a depth of 800 feet below it and found even at that depth that decomposition was in progress, as shown by the clouded appearance of certain crystals, the feldspars, under the microscope. The granite of Boulder Canyon is decom- posed on the surface. No one knows, as yet, to what depth. But the geologist has reason to suspect its solidity and must add his objec- tion to those of conservative engineers against the suggestion that the dam be built by blow- ing the cliffs into the canyon. The other type of dam proposed is to be built of reinforced concrete. Concrete may be described as a rock composed of minerals which are permanent under surface conditions because they form in that environment. Mois- ture promotes the consolidation of concrete. Age inereases its strength. So far as the superstructure is concerned, a geologist must reason that a concrete dam will outlive a rock fill dam. The engineering problem in building a concrete dam is that of excavating to solid foundations. It is, in the judgment of con- servative and experienced engineers, reasonably practicable to do so. But, if the conditions of jointing and decay of the rocks are consid- ered as they should be, it will be the geologist rather than the engineer who shall determine whether they are solid or not. The foundations are now being explored by drilling.. It is not enough. A drill may bore out a core within a foot of a weak seam and not betray its existence. The preliminary examination will, no doubt, be followed by more thorough investigation and it may be sug- gested that a method of shafts and tunnel be employed. Shafts sunk, one on each side of SCIENCE [Vou. LVI, No. 1442 the river, and connected by a tunnel at a depth of a hundred feet below the bottom of the channel, would enable a complete examination of the rock, inch by inch. Weaknesses could be excavated and filled. If they should prove too numerous at one hundred feet, the shafts could go deeper to a deeper tunnel. EHventu- ally when solid rock was found, the rock above the tunnel could be cut away to the surface, stoped, as miners say, and the stope filled with concrete would form an impervious curtain wall. Working from the bottom up, the hed of the river would be approached and the deeper foundations would. be laid without ex- posure to the risk of floods. It is not the province of the geologist to instruct engineers and I would not presume to, but the suggestion may stand to illustrate the problem of a deep and secure foundation, that the geologie con- ditions demand. The Garden of Eden was created some five thousand or more years ago by the building of huge dams of earth to control the Tigris and Euphrates, and so well did those ancient engi- neers execute their task that the beauty of the garden became a tradition of all Eurasian races. The garden endured until the state fell. Subtle forces weakened the quality of its citi- zens as moisture attacks the minerals of the granite. Our engineers can build a dam to endure for thousands of years. What is the endurance of our state? What concrete foun- dations of national character are we laying to cut off the underground activities that would destroy it? Baitey WILLIS STANFORD. UNIVERSITY EXPEDITIONS OF THE MUSEUM OF NATURAL HISTORY In one of the corridors of the American Museum of Natural History the oiicials of that institution have hung a map of the world to which labels are attached showing the dis- tribution of its exploring parties and field workers. During the present year a larger number of expeditions have been sent out than ever before. Intensive work is being pursued by each department. In the department of geology, Dr. Edmund O. Hovey is at present on a trip through Cali- Aveust 18, 1922] fornia, Oregon, Washington and _ British Columbia, securing data and photographs for the purpose of the construction of a number of relief models, showing most interesting geo- logical formation in these states. Associate Curator Reeds is working in the vicinity of New York, collecting data for a museum ex- Inbit to show the “Climates Past and Present,” and Mr. Foyles is continuing his studies in northwestern Vermont on the Fort Cassein terrain. For the department of vertebrate paleon- tology, an expedition in charge of Albert Thomson is at work in western Nebraska, seek- ing fossil mammals from the Snake Creek beds of the Pliocene age. Working in the same vicinity is Curator Matthew, who will shortly be joined by Mr. Olsen. Mr. Barnum Brown, who is well known from his success in securing most of the Brontosaurian material now on ex- hibition in the museum, is at work in the Siwalik Hills of India, obtaining fossil mam- mals and other invertebrates from a famous fossil bearing formation. In the late autumn, it is the intention of President Henry Fairfield Osborn to join the Third Asiatic Expedition, which has connected with it, in charge of paleontology, Mr. Walter Granger. Working with Mr. Granger at the present time are Pro- fessors Charles P. Berkey and Frederick K. Morris. Already extensive shipments have been made by this expedition. Mr. Childs Frick, one of the trustees of the institution, will continue fossil collecting in southern Cali- fornia, where he has already obtained an ex- tensive collection from the Pliocene. Dr. Frank M. Chapman, curator of the de- partment of birds, accompanied by Mr. George K. Cherrie and Captain O’Connell, are in Keuador continuing their studies on the distri- bution of bird life in the Andes. They will first investigate southern and southeastern Ecuador and will then conclude their work by a boat trip from Guayaquil along the coast to Paita, Peru. Assisting in the investigations in bird life in Eeuador, Henry Watkins is now engaged in the mountains of Peru. His latest shipment comes from the humid regions north- east of Lake Junin. Ernest Holt, formerly of the United States Biological Survey, is engaged SCIENCE 183 in collecting birds and mammals for the mu- seum in the mountains of eastern Brazil. A collection was recently received from him which was secured around Mt. Itatiaya. Later Mr. Holt will explore still higher peaks. The museum’s representation of bird life from this important region has until now been confined entirely to specimens in the old Prince Maxi- milian Collection. José G. Correia is under- taking the collection of birds at the Cape Verde Islands, and Rollo H. Beck, who is working under the auspices of the Whitney South Sea Expedition, is collecting in the Society Islands. Mr. Beck is accompanied by Mrs. Beck and Mr. Quayle. Mr. Griscom is doing work in New Foundland, while other members of the department are engaged in the local field. The department of mammals has G. H. Tate in Keuador. He will later be joined by an assistant in order that more intensive investi- gations of the life of mammals in this region may be studied. H. C. Raven, who accom- panied Dr. W. K. Gregory to Australia last year, has nearly completed a systematic collee- tion in Queensland and will next go to the great Nullaboa Plain in South Australia. He has already obtained for exhibition and study a series of the marsupial mammals. In September, Herbert Lang, assistant cura- tor of African mammals, will leave for British Guiana for a three months’ trip. At George- town he will join William La Varre and will go up the Essequibo River through the diamond mining district along the Mazaruni. He hopes to go through the savannah country and Mt. Koraima. By studies of the conditions in this section at first hand, Mr. Lang has an oppor- tunity to compare the ecological conditions in the great South American forests and savan- nahs with those of equatorial Africa, a com- parison which has long been needed in connec- tion with the preparation of his reports on his Congo expeditions. Dr. F. E. Lutz, of the department of ento- mology, is engaged in work in the vicinity of Boulder, Colo. F. E. Watson, of this depart- ment, recently returned from a four months’ trip to Haiti where he secured approximately eleven thousand specimens of the lower inver- tebrates, chiefly insects, and about three hun- 184 dred miscellaneous specimens of fishes and rep- tiles. He is now carrying on local field work, having in view the collection of material for several butterfly groups. R. W. Miner, of the department of inverte- brate zoology, is continuing field studies in southern New Jersey in connection with the construction of a new rotifer group. Assisting him is Research Associate Frank J. Myers, whose well equipped laboratory at Ventnor, New Jersey, is the basis of operations. Dr. Russell J. Coles is collecting material for the department of ichthyology off the coast of North Carolina. Mr. Louis L. Mowbrey has sent in some important material for this department from the Florida waters. Dr. G. K. Noble, of the department of herpetology, accompanied by Mrs. Noble, has left for the Dominican Republic. The chief object of this expedition is to secure data, pho- tographs and material toward the construction of the two habitat groups for the new Hall of Reptiles in the museum. The West Indian region is rich in reptilian and amphibian life. Perhaps the two most striking creatures in this locality are the rhinoceros iguana and the giant tree frog. Both these forms are confined to the island of Santo Domingo. The expedition will travel over a large part of the island in the course of its investigations. The rhinoceros iguana is found 'to-day chiefly in the arid south- western portion of the island in the vicinity of a dead sea, the surface of which is more than a hundred feet below sea-level. The giant tree frog has been taken only in the Central Cor- dillera and on the Quita Espuala, a range of mountains in the northeastern part of the island. It will be necessary for the expedition to carry on its work during the height of the rainy season in order to secure information in regard to the life history of the giant tree frog. Although this species is the largest and most spectacular tree frog in the world, its life his- tory is entirely unknown, and the expedition hopes to secure valuable scientifie data as well as exhibition material. While field work in the department of an- thropology is necessarily restricted for the present year, nevertheless, Mr. Nelson, of the Division of Archeology, is in Europe, engaged SCIENCE [Vou. LVI, No. 1442 in a study of the paleolithie and neolithic eol- lections in the museums abroad, and will en- deavor to secure specimens to round out the exhibition series in this museum. During his trip Mr. Nelson will visit Norway, Sweden, Spain and Belgium. Earl H. Morris, who for a number of years has been engaged on the Huntington Expedi- tion work at Aztec, New Mexico, in company with Charles L. Parnheimer, of this city, is now busy making a general reconnaissance of the Navajo mountain region of New Mexico. Dr. P. E. Goddard, of this department, accom- panied by Lieutenant G. T. Emmons of Princeton, left early in June for a trip to the Northwest Coast. It is the intention of this party to secure specimens and authentic data which will make possible an early completion of the North Pacifie Coast Hall. PROPOSED FEDERATION OF AMERI- CAN BIOLOGICAL SOCIETIES Tue second conference called to consider the question of cooperation or federation among biological societies met in Washington in the rooms of the National Research Council, on- April 23, 1922. This meeting was held in pur- suance of a resolution adopted at an informal conference in Toronto, December 27, 1921, and approved by the societies there in session. The conference organized under the chairmanship of Professor L. R. Jones, who had also pre- sided over the Toronto gathering. Plans for the 1922 meeting, in so far as they could be arranged by agreement among the officers of the several societies, were entrusted to a committee consisting of the secretaries of the American Society of Naturalists, Botanical Society of America, and American Society of Zoologists, in cooperation with the permanent secretary of the American Association for the Advancement of Science. The view was generally expressed that the conference should, if it decided to recommend any form of federation, present a definite plan of organization. A committee was accordingly raised to formulate such a plan. This com- mittee, of which Professor F. R. Lillie was chairman, reported to the conference the fol- Aveust 18, 1922] lowing recommendations, which were adopted: 1. That the vote of the Toronto conference in favor of the idea of federation be reaffirmed. 2. That the proposed federation be styled the Federation of American Biological Societies. 3. That the members of the federation be socie- ties, not individuals, and that all societies repre- sented in this conference (a list of which is given below) be eligible to charter membership. 4. That a council of the federation be estab- lished, consisting of two representatives from each society, these to be the president and secre- tary unless otherwise designated by the society. 5. That the council choose an executive com- mittee from its own membership. The committee that made the foregoing re- port was continued as an executive committee pro tempore of the conference, and to it was intrusted the task of drawing up a constitution and by-laws in accordance with the above gen- eral plan. The instructions of this committee eall for completion of its work at a reasonably early date, and the transmission of its decisions and recommendations to the officers of the sev- eral societies by correspondence. It is expected that it will be possible to distribute the pro- posed constitution and by-laws to the members of the societies early next fall. The executive committee pro tem. has the fol- lowing personnel: Frank R. Lillie, University of Chicago; C. W. Greene, University of Mis- sourl1; I. F. Lewis, University of Virginia; C. E. McClung, University of Pennsylvania; A. Franklin Shull, University of Michigan; R. E. Thatcher, Agricultural Experiment Sta- tion, Geneva; H. B. Ward, University of Illi- nois; and B. H. Livingston, representing the American Association (Herbert Osborn to sub- stitute for latter at August 4 meeting). Considerable discussion was devoted to the problem of improving biological publications, a question likely to come before the council, if the plan of federation shall be adopted. This problem was considered so important that it was deemed advisable by the conference that some action be taken without waiting for the establishment of the federation. A special committee was, therefore, appointed to work in cooperation with a committee on the same subject from the Division of Biology and Agri- culture of the National Research Council, to study the whole question of biological publica- SCIENCE 185 tions and report to the conference or to the federation if formed. The personnel of this committee is as follows: A. P. Hitchens, Army Medical School. I. F. Lewis, University of Virginia. C. A. Kofoid, University of California. D. R. Hooker, Johns Hopkins University. The corresponding committee of the Division of Biology and Agriculture of the National Research Council is composed of the following members : E. D. Ball, Department of Agriculture. C. E. McClung, University of Pennsylvania. J. R. Schramm, National Researeh Council. A. F. Woods, University of Maryland. The biological organizations represented at the Washington conference were as follows: American Association for the Advancement of Science. Sections F (Zoology), G (Botany), N (Medical Sciences), and O (Agriculture) of the American Association for the Advancement of Science. Federation of American Societies for Experi- mental Biology. The Executive Committee of the Division of Biology and Agriculture of the National Re- search Council. American Society of Naturalists. American Society of Zoologists. Botanical Society of America.

FRANKLIN SHULL, Secretary of the Conference HUIA ONSLOW At Cambridge, England, on June 27, Mr. Huia Onslow died. He was born in New Zea- land on November 13, 1890, where his father, the Earl of Onslow, was then governor-general. To commemorate the place of his birth, he was 186 given the Maori name Huia, and was regarded as the honorary chief of a Maori tribe. Queen Victoria became his godmother. Favored by circumstance, strong and handsome, he passed through Eton and Cambridge University, with every prospect of a brilliant career. But when taking a holiday in the Tyrol in July, 1911, he struck his head against a rock in diving, and was so severely injured that he became para- lyzed from the waist downward. An appar- ently helpless invalid, he was condemned to spend the rest of his life on a couch, able only to move his head and arms. Many men, so situated, would have given up all idea of useful activities, lamenting a life of supposedly un- avoidable idleness. Not so Mr. Onslow. Hav- ing been much interested in biological subjects when in college, he returned to Cambridge, secured the necessary assistants, and ardently devoted himself to biological research. Those interested in genetics will remember his papers on heredity in moths, based on breeding expe- riments carried on in his laboratory. His doubtless most important work, of 74 pages, was “On a periodic structure in many insect scales, and the cause of their iridescent colours” (Philosophical Transactions of the Royal Society, July, 1921). In this elaborate and fully illustrated paper the iridescent colors of many insects of various orders are studied, using all the modern refinements of micro- scopic technique and the latest pertinent re- searches in physics. All the drawings on the three plates are by Mr. Onslow. < 10-8 em., density (solid) 0.75. Obs. density (liquid) Young 10.7° 0.78715 M.P. 4.7°.

Some derivatives of the lactone produced by condensing cyclo-hexene oxide with malonic ester: E. ©. Kenpatt and A. E. Osrerpere. Tetra- hydro benzene adds hypochlorous acid to form ortho-chloro-eyelohexanol. This with sodium hy- droxide forms cyclo-hexene oxide, which condenses with sodium malonic ester in the same way that ethylene oxide does. The resulting lactone reacts with additional sodium ethylate giving a product which will react with alkyl halides. The proper- ties of the resulting compounds as well as those of certain nitrogen derivatives obtained from the lactones and ammonia have been studied. Derivatives of 2, £-dinitrobenzaldehyde: T. B. DowNnry with ALEXANDER Lowy. 2,4-Dinitroben- zaldehyde was condensed with a number of aro- matie amines, phenols and their derivatives, giv- ing monomolecular and dimolecular condensation OctTopER 27, 1922] products. Monomolecular condensations were effected with tolidine (also addition product), p-aminoazobenzene, chloroanilines, ete. Dimolecu- lar condensations were effected with phenol, o-chlorophenol, resorcinol, bromoresorcinol, guaia- col, dimethylaniline, diethylaniline, ete. Some of the products are dyes and indicators. The quantitative determination of acetic anhy- dride: G. C. Spencer. The proposed method is based upon the action of acetie anhydride and aniline in cold chloroform. An equivalent amount of acetanilide forms. Slight amounts of alcohol and water as found in U. S. P. chloroform do not interfere. The first attempts were made to sep- arate the acetanilide by washing the chloroform solution with dilute sulfuric acid to remove aniline separating the chloroform solution, and evap- orating to dryness in a tared beaker. The gravi- metric method was unsatisfactory. The method adopted was to hydrolyze the residual acetanilide with 10 per cent. sulfuric acid and titrate the resulting aniline sulfate with half-normal potas- sium bromate-bromide solution. Results satisfac- tory for both high and low concentrations of acetic anhydride. The estimation of aliphatic nitrate esters in the presence of certain nitro-aromatic compounds: Witserr J. Hurr and Ricuarp D. Lerrcr. On the basis for the physiological activity of certain oniwm compounds. I. Nitrogen deriva- ties: R. R. RensHaw and J. C. Wart. The pos- sible bases for the different types of physiological action of the simple and the substituted tetra- alkyl ammonium compounds are briefly consid- ered. The following new substances are described: Iodo methyl acetate, acetyl formocholine salts, methoxymethyl dimethyl amine, beta-dichloro- arsine-ethyl trimethyl ammonium chloride, beta- arsenous oxide-ethyl trimethyl ammonium chloride. Improved methods for the preparation of formo- choline and certain other choline derivatives are given. Deaminization of methyl-cis-8-amino-1,212-iri- methyl pentanoate: GLENN S. Sxinner. The de- composition of this ester with nitrous acid has been carried out on a large scale. Reaction prod- ucts are formed in the following proportions: Methyl esters of unsaturated acids, 62 per cent.; methyl esters of hydroxy acids, 36 per cent.; me- thyl esters of chloroacids, 2 per cent. The unsat- urated ester upon saponification gave lauronolic acid which was identified by conversion to the bromolactone. Three crystalline hydroxy acids have been isolated from the saponification prod- uets of the various fractions obtained by distilla- SCIENCE 489 tion under diminished pressure. One of these acids has a tertiary beta-hydroxyl and is identical with the acid of M. P. 101-2°, obtained by the decomposition of the methyl ester of the trans- isomeric amino acid. A second hydroxy acid of M. P. 121° has a secondary hydroxyl as shown by oxidation with Beckmann’s chromic acid mixture. The third hydroxy acid of M. P. 208-10° also has a secondary hydroxyl and is optically inactive. d-Ciseamphonolie acid could not be isolated. No ether acid was formed whereas the methyl ether d-ciscamphonolie acid constitutes 13 per cent. of the decomposition product of the methyl ester of the trans isomerie amino acid. Ammono formaldenydes: Epywarp OC. FRANKLIN. The ammonia analog of formaldehyde, compound of the formula CH »=N—CH,—N=CHp, is only known in the form of its dimer, hexamethylene tetramine. The methods of formation and the properties of hexamethylenetetramine are in har- mony with the view that it is a polymeric form of an ammono formaldehyde. Hydrocyanic acid, represented by the form HCN, is also to be looked upon as an ammono formaldehyde. It undergoes polymerizations and condensations, reacts with acid sulfites and hydroxylamine, and otherwise behaves in a manner closely resembling the well- known behavior of ordinary formaldehyde. International numberings of ring complexes: Austin M. Parrerson and Carnrron FE. Curran. There is at present no uniform system for num- bering parent cyclic compounds. The authors have drawn up a simple set of rules for such num- bering, with the avowed purpose of preserving as many as possible of the accepted numberings, while achieving consistency. About three fourths of the numberings used in Richter’s ‘‘Lexikon,?’ Meyer and Jacobson’s ‘‘Lehrbuch,’’ and the Chemical Abstracts indexes conform to the pro- posed rules. The matter has been taken up with the proper committees of foreign chemists with encouraging results. If their cooperation can be secured it is proposed to publish a classified collec- tion of known ring complexes, the number of which now approaches a thousand. Steric hindrance in the migration of acetyl: L. Cuas. Rarrorp and CHas. M. Wootronx. In previous work (J. A. C. §., 41, 2068) one of us has shown that when an ortho acetylaminophenol is benzoylated by the Schotten-Baumann reaction, benzoyl goes to nitrogen, while the acetyl shifts to oxyxgen. In further study of this behavior the present work was done to learn whether this rearrangement would be prevented by the pres- ence of bromine atoms adjacent to the reacting 490 groups. Acetyl-benzoyl derivatives were prepared from 2-amino-3, 6-dibromo-4-methylphenol, —2- amino-3, 5, 6-tribromo-4-methylphenol, and 2- amino-3, 4, 5-tribromo‘6-methylphenol. In case the migration was observed, which seems to indicate that the bromine atoms cause no hin- drance. The amino cresols used in this work were secured through the nitration of the corresponding brominated ortho and para cresols. When tetra- bromo-o-cresol was nitrated by Zincke’s method (J. Pr. Ch., (2) 61, 564) we obtained two iso- merie mononitrotribromo-o-cresols, in which we were able to prove that the hydroxyl and nitro radicals oecupied ortho and para relationships, respectively, in the two compounds. In this nitra- tion Zincke was able to isolate only one of these substances—the ortho product. The hydrolysis of alkyl sulfates. II: RussELu Morean and H. F. Lewis. The hydrolysis of dimethyl sulfate under the influence of acids, alkalis and salts is described and the following conclusions are drawn: (1) The higher the di- methyl sulfate : water ratio in the water hydrol- ysis, the more rapid the hydrolysis; (2) strong acids in low concentration increase the rate of hydrolysis, but in high concentration retard it; (3) the tendency in alkaline solution is for the second alkyl to come off less easily. No differ- ence between NaOH and KOH in low concentra- tion; (4) acetie acid greatly depresses hydrolysis; (5) salts depress the rate of hydrolysis, even pre- venting the splitting off of the first group; (6) the only substances acting as positive catalysts are the dilute mineral acids, a large number of which have been studied. The interaction of primary aliphatic alcohols and beta-gamma-dibromopropyl-thiocarbimide : RaymMonp M. Hann. Primary aliphatic alcohols react with this substance to form 2-hydroxy-5- BrCH,—CH—S CH,—_N=C—OH This result is contrary to that assumed by Dixon and also to the correction of Dixon’s work by Gabriel, who assumed that the product was BrCH,—CH—S CH,—N=C—OEt Aluminum arylamines: M. L. Crossuey. Alum- jnum reacts with primary and secondary aryl- amines producing aluminum arylamines and hy- drogen. Tertiary amines do not react with alum- inum. Mixtures of the three types of amines can be separated by refluxing with aluminum, dis- tilling off the tertiary amine and recovering the primary and secondary amines from the residue. every bromomethyl-thiazoline, SCIENCE [Vou. LVI, No. 1452 The aluminum compounds are readily decomposed by water and aleohol, giving the original amines, aluminum hydroxides and small quantities of sec- ondary products such as diphenylamine. The aluminum compound is very reactive and makes possible the introduction of alkyl and aryl groups under atmospheric pressure. The action of nitrogen trichloride upon unsat- urated hydrocarbons: G. H. ConeMAN and H. P. Howe tts. Nitrogen trichloride reacts with amyl- ene in carbon tetrachloride to form ammonium chloride and nitrogen gas. No more than traces of other nitrogen compounds are obtained. With butylene nitrogen forms, in addition to ammonium chloride and nitrogen, a n-chloroamine in about 20 per cent. yield. When this product is shaken with concentrated hydrochlorie acid the chlorine atoms attached to nitrogen are replaced by hydro- gen. The resulting amine still contains chlorine attached to carbon. With propylene the reaction takes place more slowly but the products are sim- ilar to those from butylene. A possible explana- tion of the failure of amine formation in case of amylene is offered. : The equilibrium between benzoin and benzalde- hyde: Ernust ANpDrERSON, R. A. JAcoBSoN and M. J. Srurzman. The benzoin condensation is found to be reversible. An equilibrium is reached between benzaldehyde and benzoin when either substance is dissolved in alcoholic sodium eya- nide. Both pure substances can be recovered from such solutions. The equilibrium is of the general type A = 2B. The amounts of benzalde- hyde and benzoin present at equilibrium in vari- ous mixtures check closely with the amounts cal- culated from the equilibrium constant. Di-beta-hydroxyethyl aniline and some of tts derivatives: FE. W. Upson and D. W. McLaren. This substance has been obtained in 70 per cent. yield by refluxing one mol. of aniline with three mols. of ethylene chlorohydrine in the presence of 30 per cent. aqueous sodium hydroxide. The product is obtained by ether extraction and frac- tional distillation of the extract under reduced pressure. Phenyl morpholine has been obtained by a similar process from _ beta-beta-dichloro diethyl ether. Di-beta hydroxyethyl aniline and phomo-morpholine have been coupled with diazo- tized sulfanilic acid giving color substances re- lated to methyl orange. The preparation of pure ortho and para aylenes: H. T. Cuarxe and E. R. Taytor. The literature dealing with the separation of the xylenes is con- tradictory and misleading. It has been found OcToBER 27, 1922] that fractional distillation, selective sulfonation, crystallization of the sulfonic acids and selective hydrolysis of the xylene sulfonie acids all tend to bring about a partial separation of the three xylenes present in coal tar xylene, but that none of these processes alone is entirely suitable for the isolation of the ortho and para derivatives. A satisfactory procedure is described in which the above processes are combined. The preparation of tetramethylene bromide: C. S. Marvrn and A. L. TanenBpaum. Tetra- methylene bromide is a research chemical often needed. Several methods have been devised for its synthesis, but none of these is satisfactory. It has been found possible to obtain the sub- stance easily by the following reactions: Br(CH.)3Br + CgH;ONa = Ph-O(CHo.)s3Br, + NaCN + EtOH + H.SO4 — Ph-O(CH,)3CO.Et, + Na + EtOH — Ph-O(CH»,)3CH,OH, + HBr — Ph-O(CH»y)sCH2Br + Br(CHe2)4Br. The yields in the steps are 80, 90, 80, 65, 40 and 40 per cent. respectively. As will be noticed the yields are good in every step except the last, where equal amounts of phenoxybutyl bromide and tetramethylene bromide are obtained. The former can be converted into the latter by pro- longed treatment with hydrobromic acid. Hydri- odie acid reacts like hydrobromie acid, giving about the same yields of the iodine compounds. Some derivatives of ethylbenzene: F. W. Sut- LIVAN, JR. Ethylbenzene was prepared in good yield by the action of ethylene on benzene in the presence of aluminum trichloride. It was found that chlorine acts on boiling ethylbenzene giving alpha chloroethyl benzene and not the beta com- pound as is stated in the literature. The cor- responding bromide was prepared. Both give phenyl methyl carbinol on hydrolysis. They also give an acetate when boiled with sodium acetate in glacial acetic acid. Styrene is obtained by passing the vapors of chloroethyl benzene over soda lime. The same substance is obtained in quantitative yield when the chloro compound is heated with quinoline. Ethyl benzene gives very good yields of the nitro derivatives when nitrated according -to the standard ‘procedure for the nitration of toluene. The preparation of aromatic alpha hydroxy acids and their esters from the cyanhydrins: G. E. Sem and Is. Kanuear. Seil’s method of hydrolysis of the cyanhydrins by means of sul- furie acid dihydrate was used on mandelic nitrile prepared from benzaldehyde. The yield of man- delic acid was 83 per cent. The ethyl ester was prepared by different methods. The isopropyl SCIENCE 491 ester of mandelic acid was synthesized and its properties were determined. The preparation of methyl red: A. W. Scuor- Ger. Methyl red is prepared by diazotizing an- thranilic acid and coupling with dimethylaniline, following in general the procedure of Tizard and Winmill. Free methyl red in the form of violet crystals is best obtained by crystallization from | acetic acid, the crystals retaining two molecules of the solvent. From the standpoint of ease of erystallization and purity of product, the best procedure is to crystallize from dilute ‘hydro- chloric acid, obtaining the hydrochloride of methyl red. The sodium salt has also been pre- pared and like the analogous compound, methyl orange, is readily soluble in water. New heterocyclic arsente compounds: ©. 8. Paumer. In the presense of two moles of sodium ethylate, one mole of primary arsine condenses with one mole of beta-beta-dichlorodiethyl ether or gamma-gamma-dichlorodipropyl ether to give compounds such ag CH,—CHy Ar—As O Nae The products are high-boiling, stable oils. They give the reactions of tertiary arsines, the arsenic readily passing to the pentavalent state by the addition of oxygen, sulfur, halogens, alkyl halides. Chloroplatinates and mereurichlorides are also formed. The above synthesis is a new reaction of primary arsines. Preliminary experiments show that the method can be applied to secondary arsines and to other halides as well as to dihalo- genoethers. Action of arsenious chloride on quinoline : Joun H. Scummr. (By title). Carbostyril and a product which preliminary analyses indicate to be tricarbostyril arsonic acid have been prepared by the action of arsenious chloride upon quinoline at comparatively high temperatures. Further investigation of this reaction is in progress. On the basis for the physiological activity of certain onium compounds. II. Arsenic deriva- tives: R. R. RENSHAW and E. R. WacGner. Sey- eral new arsonium compounds are described. Tri- methyl arsine dihalides condensed with ethylene and with formaldehyde to form the arsenic analog of neurine and formaldehydo trimethyl arsonium halides respectively. The behavior of the mercuric salts of car- boazylic acids toward heat and the structure of mercurte cyanide: Morris S. KuarascnH and 492 FREDERICK W. StTaveLy. The behavior of the mercuric salts of various substituted acetic acids toward heat has been investigated. It has been found that the reaction products depend to a very large extent upon the nature of the substi- tuted groups. In the case of the mercury salts of alkyl substituted acetic acids the mercury either replaces a hydrogen of the alpha carbon atom, or, if there is none available, no reaction takes place (compare, however, the behavior of trichloroacetic acid). In the case of the mercury salts of the phenylated acetic acids the mercury enters the ortho position in the benzene ring. However, upon heating the mercury salts of sub- stituted acetic acids, which lose carbon dioxide upon heating rather easily, a different reaction takes place: the mereury usually taking the place originally occupied by the carboxyl groups. Thus, dimethyl and diethyl acetoacetie acids behave that way. The stability of the various compounds, prepared in the course of this work, towards various reagents has also been studied, and the significance of the tests pointed out. The action of mercury on certain alkyl iodides and substituted alkyl iodides: J. Louis MAyNanp. During the present work it has been shown that the direct union of metallie mercury and methyl iodide is not hastened by ultraviolet light but is hastened by a specially arranged are light. The reaction is preceded by the formation of a small amount of mercurous iodide. If mercurous jodide is used with methyl iodide, methyl mer- curie iodide is formed rapidly. The action of metallic mercury is confined almost entirely to methyl iodide. The use of mercurous iodide makes possible the extension of the reaction to higher iodides and even to benzyl iodide. The work is being extended both to a study of the limits of the reaction and of the particular wave lengths which increase the speed of the reaction. The structure of the compounds from mercuric salts and olefines: Rocrr ApaMs, F. L. Roman, W. M. Sperry. Two different general formulas have been suggested for the products of mercury salts and olefines, true addition compounds such as HOCH,CH».HeX, and moleular compounds such as CH j:CH2:Hg(OH)X. The former have been shown to be correct by a study of the action of mercury salts on o-allyl phenols, which give products for which no reasonable ‘‘molecular’’ formulas can be written. o-Allyl phenol reacts with mercurie chloride to form 2-chloromercuri- methyl-2, 3-dihydro-benzofuran and hydrochloric acid. Treatment of this product with sodium SCIENCE [Vou. LVI,, No. 1452 amalgam gives the corresponding mercuribis com- pound. Treatment with potassium iodide and iodine gives the corresponding iodomethyl com- pound which, on reduction, gives 2-methyl-2, 3- dihydrobenzofuran. Allyl amine and mercuric chloride give a substance of the following strue- ture, which also can not be easily explained on the basis of a ‘‘molecular’’ formula: ClHg—CH,—CH—CH,NH.HCl— HCI—_NH—CH,.—CH—CH».—H¢gCl The electromotive force of organic compounds: Aldehydes: 8. B. ArnrENson and D. J. Brown. The polymerization of the amylenes: JamMus F. Norris and J. M. Jousrrt. The action of yari- ous concentrations of sulfuric acid on the five amylenes was studied. Trimethylethylene and un- symmetrical methylethylethylene were the most soluble and the most readily polymerized. In the case of these hydrocarbons no alkyl sulfuric acids were formed. The mechanism of the polymeriza- tion appears to consist in the dehydration of the alcohol first formed from the hydrocarbon. Iso- propylethylene was the only isomer which was polymerized without previous solution in the acid. The study of the products formed as the result of the decomposition of the ozonides of the polymers led to conclusions as to the structure of the dimers of trimethylethylene and isopropyl- ethylene. Improved methods of preparation of the compounds studied were found. The relationship between structure and osxida- tion potential of quinones: J. B. Conant and L. F. Fizsrr. The oxidation-reduction potential of a number of quinones is being measured in alcoholic hydrochloric acid by a titration method. The results at 25°, expressed on the hydrogen electrode seale for certain typical quinones are: benzoquinone 0.711, 1,2-naphthoquinone 0.579, 1,4-naphthoquinone 0.484, phenanthraquinone 0.471, anthraquinone 0.155. Measurements of various derivatives show that substitution of hydrogen by Cl, SO3H, COjH or COR increases the potential, substitution by alkyl lowers it. The effect of substituents is not entirely cumulative as the following values obtained with chloroquinones show: monochloro 0.736, 2,6-dichloro 0.746, 2, 5-dichloro 0.707, tetrachloro 0.695. The oxidation of tribromoaniline: W. H. Hunter and A. G. Mayrrs. The oxidation of 2,4,6-tribromoaniline by chromie acid yields almost quantitatively the 2,4, 6-tribromoanil of 2,6-dibromquinone. This reaction may be formu- lated as a benzidine rearrangement, or as a reac- tion of unsaturated radicals. OcToBER 27, 1922] The oxidation of d-mannose with potassium permanganate: W. L. Evans and R. A. Craw- ForD. The oxidation of d-mannose with alkaline potassium permanganate at 50° proceeds with the production of carbon dioxide, oxalic acid and acetic acid. The relative amounts of these prod- ucts depend on the concentration of alkali used. In neutral solutions only carbon dioxide and acetic acid are formed. At low alkalinities, all three are formed, the carbon dioxide fall- ing off rapidly and the oxalic acid rising rapidly with an increase in alkalinity to about 0.15 N, after which carbon dioxide in- creases slowly and the oxalic acid decreases slowly to 1.0 N alkali: Above this point the relative amounts of carbon dioxide and oxalic acid re- main practically constant. Acetic acid remains almost constant over the whole range. Catalytic ammonolysis of beta-naphthol in the vapor state: A. M. Howaup with ALEXANDER Lowy. Mixtures of ammonia gas and _beta- naphthol vapor were passed over a number of anhydrous oxide catalysts in a Pyrex tube at definite temperatures. A study of the yield of beta-naphthylamine was made as dependent on temperature, catalyst, rate of flow and ratio of reactants. Over a considerable range of condi- tions, yields in excess of 90 per cent. were ob- tained, together with some beta-dinaphthylamine. Curves illustrating a marked effect of tempera- ture on catalyst efficiency are shown. Deaminization of the methyl and ethyl esters of dl-alanine and aminoisobutyric acid: A. L. BarkKeER and GLENN 8. SKINNER. The methyl and ethyl esters of aminoisobutyric acid yielded largely the esters of alpha-methyl acrylie acid to- gether with a small amount of hydroxy isobutyric acid. The methyl ester yielded 3 per cent. of acid material which contained, according to the Zeisel determination, 70 per cent. of the ether acid. The ethyl ester yielded 0.5 per cent. of acid material which contained 30 per cent. of ether acid. The esters of alanine yielded the un- saturated, chloro and hydroxy esters together with a high boiling nitrogenous residue. The methyl ester gave 15 per cent. of acid material, of which 60 per cent. was the ether acid. The ethyl ester gave 2 per cent. of acid material containing 70 per cent. of ether acid. The recovery and refining of pyridine: WILBERT J. Hurr. Intermediate complex formation and electronic valence: Bren H. Nicotrr. Ortho and para iodo- amines have their iodine in a mobile state which may be described by calling the iodine ‘‘posi- SCIENCE 493 tive.’’ Two nitro groups, when o-p, produce an even more recognizably negative halogen. But, although two nitro groups thus exceed one amino group, 3, 5-dinitroiodobenzene shows no test for positive iodine; and yet, 3, 5-diamino-chloroben- zene, boiled with alcoholic sodium ethylate, shows no trace of negative chlorine. It is concluded that certain conditions favoring formation of necessary ‘‘intermediate complexes’’ are neces- sary for reaction, and that such considerations must be taken into account in judging electronic structures. The catalytic synthesis of the acetals and their halogenation: JosrpH S. Reicurert, James H. Baitry and J. A. NiruwLanp. The acetals were prepared by passing acetylene into the corre- sponding alcohols in the presence of concentrated sulfuric acid and a mercury salt as a catalyst. The products of the chlorination and bromination of dimethyl and diethyl acetals were determined. The chlorination of diethyl acetal gave a good yield of chloral. Chloral was also prepared by the successive action of acetylene and chlorine on ethyl alcohol. After the required amount of acetylene had been absorbed, the reaction mix- ture was chlorinated directly without the separa- tion of the acetal. In this process one mol, of acetylene takes the place of one mol. each of aleohol and chlorine as compared to the ordinary process of making chloral from alcohol. New derivatives of 2-bromo-6-hydroaxy-1, 4- naphthoquinone: Auyin §S. WHEELER and B. Narman. The preparation of 2-bromo-juglone as given by Wheeler and Scott was improved upon. Its benzoate was prepared. Its bromine was re- placed by chlorine by means of alcoholic hydro- chlorie acid. The benzoate of the chloro com- pound was prepared. A dibromojuglone was made by brominating a hot glacial acetic acid solution of the monobromo compound. The sec- ond bromine entered the quinone ring and none entered the phenol ring in spite of the faet that juglone readily takes up two in the quinone and one in the phenol ring. Both bromines can be replaced by chlorine by means of alcoholic hy- drochloric acid. Acctates and benzoates were prepared. The polymers of pinene. II: G. B. FRANK- FoRTER and Berry SuuuivAN. Improved methods have been worked out for the preparation of the compounds already described, namely, colophene, (Cy¢Hi6) 2, and colophonene, (Cy Hi) 5, to- gether with new derivatives of the same. In ad- dition to the above, new compounds have been obtained which complete the series, namely, the 494 sesquicolophene, (Cy 9H g)g, and the dicolophene, (CyoH16)4-. The properties of the latter resemble the former in their remarkable stability and in the difficulty with which they form derivatives. Some sulfonic acid esters of phenylazophenol and its substitution derivatives: C. E. Boorp, M. D. Counter and HeLen L. Wikorr. (Lan- tern). Several esters of benzene sulfonic acid, p-toluene sulfonic acid and alpha naphthalene sulfonic acid with phenylazophenol and its sub- stitution products were prepared by the Bau- mann-Schotten method. The twenty-one esters thus prepared for the first time, together with the fourteen previously described (Ber., 28, 800, 31, 1782, 2116; J. Pr. Ch., 78, 386), are all sta- ble, easily purified, beautifully erystalline com- pounds melting between 50° and 200°. It is sug- gested that this type of derivative may be of value in characterizing the sulfonic acids. The para derivatives such as p-tolylazophenol and p-chlorophenylazophenol seem best adapted to this purpose. Practical preparation of oxalic acid from acetylene: SistrR Mary Lucretia, Lro J. Hetser and J. A. Nreuwtanp. Oxalie acid can be prepared on a practical scale by passing acetylene into a mixture containing three vol- umes of nitric acid to one volume of water and about two per cent. mercuric nitrate. The forma- tion and loss of nitrogen oxides in the reaction prevents the commercial use of the process. The reaction proceeds through the formation of an intermediate compound which yields aldehyde, which is then oxidized to oxalic acid. Oxalie acid can be prepared by the direct action of nitrogen: oxides on acetylene, by the action of acetaldehyde with nitric acid (3:1), and by the action of nitrogen oxides on aldehyde vapor. Acetaldehyde can be prepared by the action of acetylene on dry mercuric nitrate, by the action of acetylene on the compound obtained by treating metallic mer- cury with nitrogen oxides. The oxidation of propylene glycol with lithium, sodium and potassium permenganates: E. OC. Hytree and W. L. Evans. (a) Propylene glycol is oxidized by neutral permanganate solutions to carbon dioxide and acetic acid at 25° and 50°. Above certain minimum concentrations of alkali oxalic acid is also obtained. (b) The amount of each oxidation product at low alkalinities is influ- enced not only by the concentration of the alkali, but also by the use of either lithium, sodium and potassium hydroxides in connection with each of the several permanganates. Hexabromodiphenyldisulfide: W. H. Hunter SCIENCE [Vou. LVI, No. 1452 and A. H. KouuHasre. This compound is ob- tained by treating the silver salt of tribromothio- phenol with iodine in benzene solution. This ac- tion is normal, and by so much is contrary to the action of iodine on the salts of halogenated phenols to form polyphenylene oxides. Further, molecular weight determinations .in various solvents give consistently low results, apparently showing dissociation of the substance and conse- quent existence of the free radical CgH2BrsS, which does not lose halogen spontaneously. Formation of gouwmaric acids and substituted gamma-butyric acids from resorcinol, orcinol and phloroglucinol: W. D. Laneury and RoGEr Apams. While attempting to prepare certain complex ketones, it was found that beta-chloro- propionitrile and gamma-chlorobutyronitrile do not condense with resorcinol, orcinol or phloro- glucinol in the presence of zine chloride and hydrogen chloride as nitriles ordinarily do to give ketones, but instead condense to give acids, (HO )oCgH3CH CH 2COoH, ete. Alpha-beta- unsaturated nitriles give the same type of con- densation product, indicating without doubt that with these compounds the first step is the addition of hydrogen chloride to the double bond. A new method of preparing unsaturated 1, 4- diketones: J. B. Conant and R. E. Lurz. Sub- stances of the general type RCOCH=CHCOR are of interest because they contain the characteristic linkage of quinone and indigo. Only a relatively few representatives have been previously pre- pared and the methods of preparation are diffi- eult. We have prepared a number of aryl unSat- urated 1,4-diketones by the action of fumaryl chloride, aluminum chloride, and an aromatic hydrocarbon. The yields are good. It is inter- esting that these substances are all smoothly re-— duced to the corresponding ethane derivatives by sodium hydrosulfite or titanous chloride in con- trast to ketones of the type RCH—CHCOR, or™ acids of the type HOgCCH=CHCOH, which are not reduced by these reagents. The preparation of hydroxypyruvic acid: W. L. Evans and G. P. Horr. The following steps were used: (1) pyruvic acid, (2) monobromo- pyruvic acid, (3) its methyl ester, (4) methyl ester of hydroxypyruvie acid, (5) hydroxypyruvie acid. The conversion of (3) to (4) was accom- plished by means of methyl alcohol and potassium formate, (5) is easily obtained from a slightly acidulated aqueous solution of (4). CuarLes L.

However, it was rather because of this differ- ence that I ventured to accept. I found a cer- tain justification on the ground that if in the main these evenings are given over to the re- porting of advances in knowledge, one evening might conceivably be profitably devoted to a consideration of whether we are preserving these advances in such a way that the greatest use may be made of them with a minimum ex- penditure of time, energy, and funds. We ex- pend considerable funds and enormous amounts of energy and time in ascertaining new facts and publishing them in extenso. I believe it is pertinent to inquire whether we have estab- lished adequate means for so recording these facts that the greatest and most economical use is made of them and progress made as largely cumulative as possible. No doubt some of you are wondering what special license I have to discuss this problem. I can answer only that I have none. My con- tact with the subject has been a brief one. I happen to ‘be one of a number who for the past four years have been carrying some of the responsibility in connection with Botanical Ab- stracts, and as such have been impressed with the magnitude of the problem of properly re- cording our information and have become con- vineed that in a large measure we have not in 1 An invitation paper given at the Marine Bio- logical Laboratory, Woods Hole, Massachusetts, August 4, 1922. 496 our present methods reached a fundamentally correct solution of this important problem. The ideal—I take it all are agreed here—is to have all new information so recorded that any part of it, major or minor, can be located promptly and certainly. Classified bibliogra- phies and indexes, in book or ecard form, ab- stracts with subject and author indexes in book form, ete., are some of the means in use to approximate this ideal. I should make it clear that I am here discussing only the recording of information, not criticism. A review of most of these agencies, at least the biological ones, shows that they have been very inadequately supported, have been able at best to do the work incompletely, great as has been the service they have rendered. And, per- haps more important, continuity, because of inadequate financial support, has not been guaranteed, with the result that agencies have arisen, grown to great usefulness, declined, and disappeared, to be followed by gaps before other agencies have got under way. The result is that biological literature is not only inade- quately recorded, but it is recorded in so many places that the task of rather exhaustively con- sulting the literature on many biological sub- jects is indeed exhausting. Moreover, an enor- mous amount of duplication exists, all agencies in the same general field covering the literature in well-known journals, but frequently being forced to neglect that in the less well known. I believe it is worth while to inquire into the fundamental causes of the difficulty and just what sort of service the present worker demands. As the number of research journals and the amount of material published have steadily increased it has become more and more impossible for the individual worker personally to subseribe for an appreciable amount of the literature in his field. More and more he is depending wpon bibliographie and abstract services to bring to his attention the contribu- tions he must consult evitically. It could not be otherwise. But in general the workers desire to own these bibliographies or abstracts, especially the latter, as they constitute, if well done, a sort of master key to the literature. I believe I am correct in saying that usually workers prefer a good abstract journal cover- ing their field to a single or even several re- SCIENCE [Vou. LVI, No. 1453 search journals. Granting that workers need and want most of all adequate abstract and index services, it is clear that if they are to avail themselves fully of such agencies these must be procurable at prices within their reach. In other words, the cost of the service must be relatively low—very low for most of us. See- ondly, the service must approximate complete- ness. It should be of such character that reli- ance can be continuously placed on it to report adequately practically all the literature. Thirdly, the service must be prompt; the de- mands of the worker on his abstract journal are much like those on the newspaper. Fourth- ly, there should be reasonable guarantees of the continuity of the service. é As regards completeness and adequacy, I be- lieve only one type of service has been devel- oped which is generally satisfactory and that is the abstract journal with detailed indexes. Classified bibliographies, even though based on an examination of the texts, can at best but incompletely record the new information, though their utility has been and is very great, especially for libraries. In some instances, notably in the case of libraries, classified bib- liographies in card form are preferred; but for individuals the expense and labor involved in filing and files have not made these very popu- lar. Moreover, such bibliographies are cumu- lative and not periodic. The same objections presumably hold for abstracts in card form. Another objection to the latter is that it is difficult to accompany them by a usable de- tailed subject index. The reason for the popularity of abstracts with detailed indexes is obvious. Unlike bib- liographies, abstracts, if well prepared, quickly give the reader definite information as to the exact content of contributions. In many eases the titles can not do this even though formu- lated with care; and many of them are not formulated with care. Indeed, many are dis- tinetly cryptic. From complete abstracts vir- tually complete subject imdexes can be pre- pared, based, of course, on a careful analysis of the abstract as well as of the title. By and large, the complete. subject index is perhaps of the greatest importance. But its preparation necessitates complete abstracts, unless indeed the indexing should be done wholly from the Novemeer 3, 1922 originals—which would not at the same time yield the much desired abstracts, indispensable for current and reference use. It seems logical, therefore, to prepare the abstracts, and from them the indexes. Annual indexes furnish periodic reference sources which may be cumu- lated from time to time, as desired, to furnish the cumulative reference sources. If we are correct that the most useful instru- ment in general is the abstract journal, how are we to produce it completely, thoroughly, promptly, continuously and sufficiently cheaply to answer the requirements? Obviously the task requires funds. At present there are a great many abstract- ing journals in biology, not to mention scores of research journals that make more or less abortive attempts at abstracting. The sub- seription list of each is small, as most of them serve small groups. We have set up a great many special abstracting journals—in bacteri- ology, physiology, entomology, endocrinology, systematics, phytopathology, ete., ete..—in most eases without correlation, with the result that each can claim only a small list of subscribers and is forced to charge a high subscription rate. It is a fact too often lost sight of that composition, or type-setting, is expensive and that its cost per page is the same whether one or one hundred thousand copies are printed. The fewer the subscribers, the larger the share of composition charge each must bear. With a large subscription list, the amount borne by each becomes negligible and a copy costs little more than the paper, press work, binding, and distribution. An abstracting journal with a subscription list of one thousand or fifteen hun- dred, as is the case with most of them at present, can not hope to yield a surplus suffi- cient to carry on the large amount of exacting routine necessary in a good abstracting journal. Little wonder, then, that almost all our special biological services are embarrassed financially and unable to carry their work forward as it should be carried. Let us at this juncture examine what has been and is being accomplished by another science group going at the problem in another way. I refer to the chemists, who are probably handling the proposition more successfully SCIENCE 497 than any other group. Instead of abstracts of industrial chemistry, organic chemistry, phar- maceutical chemistry, analytical chemistry, inorganic chemistry, ete., ete., they have one chemical abstracts. They have made it one of the official organs of the American Chemical Society and thus insured a minimum circula- tion of well over 13,000. The following are the remarkable facts in this undertaking: Chemical Abstracts publishes annually approx- imately 5,000 pages of probably the best ab- stracts and indexes produced anywhere; it maintains an editorial office, consisting of an editor-in-chief, two associate editors and a clerical staff, and pays its abstractors at a per page rate, at an annual cost of approximately $26,000; but even so, the journal is produced at an annual cost of about $6.80 per member, this including entire cost of manufacture and distribution, support of the editorial office and compensation of abstractors. Consider for a moment another journal, Botanical Abstracts, with which I happen to be familiar. It prints about 1,200 pages of abstracts annually at a cost of $12.00 to each of its 1,100 subscribers, and has not only yielded no income for editorial purposes or for compensating abstractors, but instead has ‘been accumulating a deficit. In other words, Chem- ical Abstracts publishes four times as much material at less than half the price and is able to carry its work forward continuously and efficiently and be relatively free from serious financial embarrassment. Most of our special abstracting journals are being carried on by a few enthusiasts willing to devote much time and energy without compensation. But, how- ever willing these individuals may be, such or- ganizations are subject to frequent partial or complete breakdowns. Their continuity and uniform quality have no reasonable guarantees. Is it possible for the biologists to profit by the experience of the chemists and achieve something equally good or better in the way of this important accessory mechanism? At once we realize that the biologists lack an organiza- tion sufficiently comprehensive and strong to grapple with so large and difficult a problem. There are in this country fifteen to twenty soci- eties of biologists with an aggregate member- 498 ship of over 6,000, but, with the exception of the Federation of American Societies for Ex- perimental Biology which involves four socie- ties, these have been almost wholly uncorre- lated. Recently, however, there has developed a movement which may provide an organization comprehensive enough to measure up to the task. I refer to the proposed federation of American biological organizations which are of a research character and which are essentially national in scope. This movement, as seems not generally realized, began over a year ago when the Botanical Society of America, the American Society of Zoologists, and the Amer- ican Society of Naturalists endeavored to work out some plan to provide for the organization desired by the geneticists without at the same time increasing the already large number of separate and distinct biological organizations and thereby making it still more difficult to handle problems of common concern to all biologists. It was recognized that the oppor- tunity for the organization of special groups must be provided, but also that there are cer- tain large problems which can be properly handled only by a larger, stronger organization, including, if possible, all the societies. As re- gards the immediate problem of the genetics organization, the committee of the three socie- ties recommended that sections in genetics with common officers be created in both the Amer- ican Society of Zoologists and the Botanical Society of America. This recommendation was carried out by both societies, and programs of the joint sections were held at Toronto. The committee went further, however. It recognized that similar organization problems would continue to arise and that something should be done to make such organization of special groups possible and at the same time maintain a certain solidarity of biologists for handling problems of common concern requiring concerted action for their successful solution. It was felt that this could be accomplished by a federation of at least the national research biological organizations. The Division of Biology and Agriculture of the National Research Council was requested to call an informal conference at Toronto of officers of the national societies to consider the SCIENCE [Von. LVI, No. 1453 possibility of a federation. This meeting was held? and, after a general discussion, it was voted to hold an adjourned meeting in Wash- ington in the spring. This was held in April of this year* and was participated in by official representatives from the following organiza- tions: American Society of Zoologists. American Genetie Association. American Society of Naturalists. American Phytopathological Society. Ecological Society of America. Botanical Society of America. American Society for Horticultural Science. Society of American Foresters. Society of American Bacteriologists. American Association for the Advancement of Science, and its Sections G, F, O, and N. American Association of Economic Entomolo- gists. American Society of Agronomy. Entomological Society of America. Federation of American Societies for Experi- mental Biology. Amenican Dairy Science Association. American Society of Animal Production. An executive committee pro tem. was ap- pointed to draw up a constitution to be sub- mitted this fall to the societies represented in the federation conference. While I am not authorized to speak for the committee, I think it may be said with perfect propriety that the federation, if established, will not in the least affect the autonomy of the member societies and that it will concern itself with problems of common concern to biologists.* The Wash- ington conference recognized that one of these problems, perhaps the chief one at present, is publication, and, in particular, abstracts. It therefore appointed a committee to study the problem of providing all of biology with ade- quate abstracting and indexing services. This committee is a joint one, half appointed by the Conference and half by the Division of 2See Shull, A. F.: ‘‘The Proposed Federation of Biological Societies,’?

NOVEMBER 3, 1922] Biology and Agriculture of the National Re- search Council, and consists of the following: Representing the proposed federation: A. Parker Hitchens, D. R. Hooker, C. A. Kofoid, I. F. Lewis. Representing the Division of Biology and Agri- culture: E. D. Ball, C. E. McClung, J. R. Schramm, A. F. Woods. This committee is at work ascertaining the exact situation in abstracting, indexing, and other agencies for recording biological infor- mation throughout the world. Several facts are already obvious. Considering for the mo- ment only the agencies published in English, we have in this country Abstracts of Bacteri- ology, Index to the Literature of American Economic Entomology, Botanical Abstracts (containing in addition to plant research animal cytology amd_ genetics), EHndo- erinology, ete.; in England, Physiological Ab- stracts, Review of Applied Entomology, Review of Applied Mycology, Zoological Record (Part N of the International Catalogue of Scientific Literature), ete. The subscription list of each is small and in many eases the financial sup- port is inadequate to insure that the work will be done thoroughly and in perpetuity. Zoology especially seems in a precarious position since the breakdown of continental agencies and the suspension of the International Catalogue, with the exception of Part N (Zoology), which, however, is financially handicapped. Only in physiology and entomology, and perhaps genetics, is the situation reasonably satisfactory at present. Many of the agencies are hanging on a relatively slender thread; some are likely to break down at almost any moment, indeed, are breaking down. The question is, shall we continue to leave the recording of biological information, only a mechanism, to be sure, but an absolutely indispensable one, to such a pre- carious existence? Primarily there appear to be two methods of handling the situation. (1) The present one of a large number of special abstracting journals or bibliographie services. For such special journals there is a relatively small de- mand and a correspondingly small support. Here, too, it should be pointed out that the more numerous the journals and the narrower SCIENCE 499 the field covered by each, the greater the amount of duplication—necessary duplication under this system since each specialty grades insensibly into neighboring ones on which it depends to a large extent. Furthermore, the conventional line so often drawn between plants and animals is no longer recognized in many lines of work, and rightly so. Separate botan- ical and zoological abstracting journals will not satisfy the geneticist or eytologist, and only im- perfectly many pathologists, physiologists, and ecologists. (2) The other method is the pub- lication of a single comprehensive biological abstracts, corresponding to Chemical Abstracts. Let us consider the second alternative in more detail. (1) Cost. The joint committee has not yet completely determined the approximate volume of biological literature, after delimiting it roughly from clinical medicine, chemistry, physies, geology, psychology, ete. But it is safe to assume that it is at least as large as chemical literature. Let us assume, then, that a journal fully as large as Chemical Abstracts (5,000 pages annually) would be required. If such a journal were made the official organ of the proposed Federation, going to each mem- ber of the constituent societies as Chemical Ab- stracts goes to each member of the various sec- tions of the American Chemical Society (thus insuring a subscription list of 7,000 or 8,000), I believe I am safe in saying on the basis of information in our hands on manufacturing costs that such a journal would cost little or no more than most of the special abstracting journals and considerably less than some of the larger ones like Botanical Abstracts. In other words, a very large journal with a large sub- scription list would cost less per subscriber than a small one with a small subscription list. Let me remind you again of Chemical Ab- stracts with its 5,000 pages annually and an overhead of $26,000 yearly produced at a cost of $6.80 for each member. It may be objected that most biologists would be interested in but a small part of such a comprehensive journal. The same thing may be said of Chemical Abstracts. I doubt whether there would be greater diversity than in Chemi- cal Abstracts, which includes anything from 500 routine commercial analysis to theoretical physical chemistry. The material would, of course, be organized into sections according to the judgment of the biologists and the section or sections of interest could be as easily con- sulted as in a special journal. This objection resolves itself, I believe, into the relatively small item of space occupied on the shelf; this may perhaps be met by some plan of issuing parts without involving a sacrifice of the fundament- ally important principle of uniform support by all members of the constituent societies of the proposed Federation. (2) Duplication. Most of the duplication existing in special abstracting journals would be done away with and the problem would nar- row itself down to the necessary overlapping with a few large abstracting journals in ‘the other major fields—chemistry, physics, ete. Moreover, with such a widely distributed ab- stract journal, research journals might well dis- continue their abstract sections and either de- vote such space to the publication of addition- al research, or to criticism, or both; or effect a reduction in size, and consequently in cost. (3) Cross referencing. Though the ma- terial be segregated into special sections, as many as necessary, suggestive and pertinent material from other sections could be conveni- ently referred to by cross references, each sec- tional editor having complete control over cross references by having access to a complete dupli- cate galley proof. (In the special journals this can be done only by duplicating in large measure the abstracts appearing in other spec- jalized journals.) This cross-referencing would make possible the very complete utilization, with practically no expense, of the valuable leads from related fields on which so much of prog- ress depends. (4) Current files. A single, large, strong journal could aequire by exchange or purchase much of the current serial literature in which its material appears. Chemical Abstracts now receives 550 serial publications, by exchange and purchase, which are available for abstract- ing purposes. The small journal does not have the resources to accomplish this, and yet such files are indispensable for properly carrying on the work. It is to be hoped that some day all SCIENCE [Vou. LVI, No. 1453 American abstracting agencies at least may be brought into correlation in order that they may share each other’s facilities; all the services would inevitably profit by such correlation. (5) Support. Fundamental to the ultimate success of such a comprehensive undertaking would be the adoption of the journal as an of- ficial organ of the proposed Federation. Grant- ing that it can be manufactured, as I believe it ean, for from $6.00 to $8.00 annually, I am inclined to believe that practically all of us would be willing to pay that amount annually for a virtually complete abstracting and index- ing service of the world’s literature in our re- spective fields, especially when it brings in ad- dition equal service in other biological fields in which we have an interest. If this were done, in other words, if a Biological Abstracts, or whatever you choose to eall it, had the solid backing of the biologists of America at least, support, perhaps a permanent endowment, might be secured sufficient to cover the over- head, in which ease the journal could be sold for practically manufacturing cost. Moreover, such an endowment would reasonably guarantee that the work would go forward properly un- der practically all conditions. There is little hope that the numerous separate journals with small backing can command such support. In- deed, the history of these shows that they can not. Let me make it clear, however, that the joint publications committee has no power. Its fune- tion is to ascertain and report the facts. The decision rests with the societies. The committee is by no means ready to report, and I have little idea as to what will be the nature of its report when all factors have been taken into consideration. But I personaliy venture to pre- dict that the permanent solution of the problem lies in the direction of the establishment of a single biological abstracting journal having the unified support of all, or practically all, Ameri- ean biological organizations at least. Obvious- ly, such a solution would necessitate the merg- ing of several existing biological abstracting and bibliographic agencies, and this, of course, should not be done unless it is certam that a real improvement will be effected thereby. We may rest assured that those controlling the ex- NovemMsrr 3, 1922] isting journals will not proceed in this direction until such guarantees are forthcoming. J. R. Scuramu National RESEARCH CoUNCIL, WASHINGTON, D. C. DOES NITRIFICATION OCCUR IN SEA WATER Despite the meager, observational and ex- perimental data which are available on the sub- ject, the idea of the occurrence and activity of nitrifying bacteria in the opea sea is widely prevalent among bacteriologists and botanists. This idea is based, in part, on the reasoning that ocean water should contain the bacteria discharged into it by the sediments and the drainage waters from terrestrial sources; more particularly, however, it is an outgrowth of certain studies which have been made in recent years on the bacterial flora of sea water which, as above indicated, are far from exhaustive and satisfying. for example, Thomsen? has dis- covered nitrite and nitrate producing bacteria in the ooze of the bottom of Kiel Fjord. It has also been reported that nitrite and nitrate forming bacteria have been found in the slime at the bottom of the Bay of Naples. In both cases, however, it is definitely pointed out that the samples studied were obtained from near . land surfaces. Moreover, Thomsen failed to discover the nitrite or nitrate forming organ- isms in sea water or in the plankton or the fixed alge. In commenting on the studies of Keding? and Keutner* on nitrogen-fixing bac- teria of the sea, Drew* made the following statement which shows him to have been con- fused on the subject of two distinet groups of ‘“Ueber das Vorkommen von Mess. Meeresunters, 1 Thomsen, R.: Nitrobakterien im Meere, Vol. XI, Riel. 2 Keding, M.: ‘‘ Weitere Untersuchungen iiber stickstoffbindende Bakterien,’’ Meeresun- ters, Vol. IX, Kiel. 3 Keutner, J.: ‘‘Ueber das Vorkommen und Verbreitung stickstoffbindende Bakterien im Meere,’’ Ibid., Vol. IX, Kiel. 4 Drew, G. Harold: ‘‘On the Precipitation of Calcium Oarbonate in the Sea, etc.’’ Papers from Tortugas Laboratory, Carnegie Inst., Wash., Vol. 5, 1914. Wiss. SCIENCE 501 bacteria wholly different from each other in all respects. He said, “The existence of nitrify- ing bacteria which are capable of absorbing and combining with the free nitrogen of the air> and eventually give rise to nitrates, has been shown by Keding and Keutner, but these have so far only been found in the bottom close to shore or apparently living in symbiosis with alge or plankton organisms.” Later on, however, Issatchenko,* whose original papers are not available to me, claims to have found nitrifying bacteria in the Gulf Stream near Ekaterininsk 72° N. He observed, however, that the presence of such bacteria in the Arctic Seas is still unproved. Issatchenko made this statement eight years after having stated, as reported in a brief note,’ that he had discov- ered a nitrifying bacterium in Arctic sea water. With these unsatisfactory results before him, Berkeley’ decided, in the course of other studies on marine bacteria, to make some tests for a possible nitrifying power of sea water. He inoculated 2 per cent. solutions of ammo- nium sulfate in sea water with samples of the sea water to be studied. He does not state how much inoculum was employed, nor any- thing else relative to the technique of the ex- periments, but the result was that even after three months none of the cultures showed even traces of nitrite or nitrate. In connection with a series of critical studies on the possible connection of bacteria with CaCOs3 precipitation in sea water, which are to appear in the reports of the Department of Marine Biology of the Carnegie Institution of Washington, the writer of this note, unaware of Berkeley’s work which appeared at about that time, determined to make some tests for the possible nitrifying power of sea water. 5 Italics mine. 6Issatchenko, B.

Can., Vol. 13, p. 15. 502 The first tests were carried out at Pago Pago in American Samoa, but they were later sup- plemented by several tests at Berkeley, Cali- fornia, with material collected in Samoa. In the tests just mentioned, the ordinary Omelian- sky solutions for nitrite and nitrate formation were employed, and they were inoculated in two series, one with sea water and the other with caleareous sand taken from beneath that same sea water. Twenty-five ce. portions of sea water and about one gram of the calcareous sand were used as inocula. After three weeks, there was no trace of nitrite or nitrate in the sea water inoculation, but very good nitrifica- tion in the caleareous sand inoculations. The first result is, therefore, in agreement with that of Berkeley, though reached in ignorance of Berkeley’s experiments. It will be noted, however, that Berkeley used sea water media containing 2 per cent. of (NH4)2SOu., which is very different from the weak salt media of the Omeliansky solution which contains only .1 per cent. (NH4)2SOs. In fact, there seems to be no real reason for the use of such high concen- trations of ammonium sulfate, and especially in the presence of a concentrated salt solution like sea water. Nevertheless, the agreement in the results of the two tests is noteworthy. Be- fore discussing further the significance of my second result, namely, with the caleareous sand inoculations, it is best to deseribe some sub- sequent experiments. Thinking that the period of incubation may have been too short in the sea water cultures above described, since the nitrifying bacteria could not in any case be expected to be present in sea water in great numbers, I repeated the experiments on my return to California from Samoa, and allowed the culture to run for eight months in one ease. The results were, however, just the same as in the first series. The inoculations with sea water gave no tests for nitrite or nitrate, and the inoculations with caleareous sand taken directly below that sea water gave marked nitrification. Even these tests did not entirely satisfy me, however, because I still thought that the num- ber of nitrifying bacteria in sea water might be so small as to render possible their total absence from a 25 ec. sea water inoculum. An SCIENCE [Vou. LVI, No. 1453 opportunity to make further tests came, how- ever, during my continued studies on marine bacteria and the lime precipitation problem during the past summer (1922), this time at the Tortugas Laboratory of the Carnegie In- stitution of Washington. On June 9, two 150 ee. portions of Omeliansky’s solution were placed in one liter Erlenmeyer flasks and ster- ilized. When the culture solutions were cool, they were inoculated as follows: one with about ten grams of calcareous sand obtained from the sea bottom near the Loggerhead Key shore; the other with 150 ce. of sea water ob- tained immediately above the calcareous sand. On June 16, tests were made with Tromms- dorff’s reagent of the cultures, which were incubated at room temperature (about 27° to 31° C. constantly). No test for nitrite was obtained in either culture. On June 22, the tests were made again. This time, the eal- eareous sand inoculation showed marked nitrite production, whereas the other culture showed nothing. A further test made on July 21 gave the same results as that on June 22. All of these itests, taken in conjunction with those of Berkeley and possibly those of Isaat- chenko, compel us to the conclusion that either the nitrifying bacteria are absent from the sea water, or they can not function in such concen- trated salt solutions. The former alternative is probably the correct one, since it will be re- membered that my first tests were with much weaker salt solutions, and as Miss Meek and I have shown in a paper soon to appear in the Journal of General Physiology, the nitrifying bacteria can withstand very high salt concen- trations. It may, therefore, be concluded with reasonable safety that the nitrifying bacteria are absent from open sea water and that, there- fore, no nitrification occurs in such sea water. What may be the state of affairs in small areas of the sea close to land and harboring much organic matter is not directly relevant to this particular inquiry. I hope to secure some information on that point soon. Not tne least interesting feature of my tests on this question, however, is the result ob- tained with the calcareous sand inoculations. It is remarkable that calcareous sand, which is in constant contact with sea water, should har- NoveMBrErR 3, 1922] bor vigorous nitrifying organisms, whereas that sea water with which it is in equilibrium in the system should not. It is difficult to account for this, except by assuming that the solution surrounding the sand particles is of a very different nature from that in the sea water above, and yet the possibility of that seems rather remote. Of course small amounts of organic matter covering the sand particles may afford protection for the bacteria. Fur- ther experiments which I am conducting may throw some light on this question. Cuas. B. Lipman UNIVERSITY OF CALIFORNIA A RECENT SCIENTIFIC EXPEDITION TO THE ISLANDS OFF THE WEST COAST OF LOWER CALIFORNIA At the Berkeley meeting of the Pacifie Divi- sion of the American Association for the Ad- vancement of Science in 1921 there was ap- pointed a Committee on Conservation of the Marine Life of the Pacific, Dr. Barton Warren Evermann, chairman. One of the first tasks which the committee undertook was the making of recommendations for the protection of cer- tain of the marine mammals or for the gather- ing of necessary information which would make it possible to advocate a concrete plan in the future. With regard to certain species, there already existed sufficient data so that definite action could be undertaken at once, but with other species practically nothing was known of their present status. This was notably true of the Guadalupe elephant seal, Guadalupe fur seal and southern sea otter, all of which once existed in great abundance along the shores of California and Lower California. Through the activities of the committee, an expedition was dispatched from San Diego to the islands off the west coast of Lower Cali- fornia on July 9, 1922, for the primary pur- pose of securing data on the three above men- tioned species of mammals. The government of Mexico provided the fisheries patrol boat Tecate for the work and met all expenses while the party was in the field. Professor Carlos Cuesta Terron, curator of fishes and reptiles of the National Museum of Mexico, was in charge of the expedition and the Mexican gov- SCIENCE 503 ernment was further represented by Professor José M® Gallegos, of the National Museum, Sis. Joaquin Palacios, inspector, and Rudolfo Lascano, assistant inspector of lighthouses, Sr. Enrique Gonzalez, fisheries inspector, and Sr. Luis Rubio, taxidermist. Through the intercession of Dr. A. L. Bar- rows, of the National Research Council, the National Geographic Soeiety rendered financial assistance which made it possible for the com- mittee to enlarge the scope of its work by securing the cooperation of the California Academy of Sciences, represented by Myr. Joseph R. Slevin, assistant curator of herpetol- ogy, Mr. Frank Tose, chief taxidermist, and the writer; of the San Diego Society of Nat- ural History, which sent Mr. A. W. Anthony, curator of vertebrates, and Mr. Ernest Hinkley, assistant; and the Scripps Institution for Bio- logical Research, represented by Mr. P. S. Barnhart. Mr. Anthony and ‘the writer were placed in charge of the scientific investigations. The motor ship Tecate was admirably suited to the work in hand and the success of the expedition was in no small measure due to the constant interest of Captain Victor Angulo and his well trained crew. Everything possible was done to aid the observers and collectors during the five weeks in the field. The expedition returned to San Diego on August 16, after having visited the following islands: Guadalupe, San Martin, Cedros, the San Benitos, Natividad, San Roque, Asuncion, Magdalena and Santa Margarita. Landings were also made at Ensenada, San Quintin Bay, San Bartoleme Bay and Abreojos Point on the Lower California peninsula. Besides making collections at all of these places the coast line was studied at close range for considerable dis- tances from the vessel, particularly the bighi, known as San Cristobal Bay, where elephant seals are known to have once hauled out in numbers. The herd of elephant seals on Guadalupe Island was carefully studied and counted and, although ‘the results can not as yet be an- nounced, it -may be stated that conditions were very encouraging for the perpetuation of this remarkable species. Many interesting photo- graphs, including motion pictures, were taken of the animals. 504 The entire coast lines of Guadalupe and sevy- ‘eral of the other islands were examined care- fully for evidence of the existence of the Guadalupe fur seal but not a single animal was seen. Many inquiries were ‘also made regarding the species but no information was obtained which would indicate that there remained a living representative. It has apparently gone the way of the great auk, Steller’s sea cow and several other valuable species; commercial hunters can cut another notch on their gun- stock. The old fur-seal rookery grounds of Guada- lupe were examined carefully. Three of these were found and the lava rocks were polished as smoothly as though they had been deserted but yesterday. An estimate based upon knowledge gained on the Alaska fur-seal rookeries placed the original number of animals on Guadalupe at 100,000. The great killing took place in the early part of the nineteenth century and we must look with remorse upon our ancestors who were so thoughtness as to destroy so val- uable an animal. In 1892 and subsequently several expeditions have visited Guadalupe Tsland in the hope of securing specimens for museum purposes but met with no success. Four incomplete skulls upon which the species was founded and possibly a few disassociated bones (yet unidentified) taken by the last ex- pedition seem to represent all there is of it except regrets. No southern sea otters were seen by the mem- bers of the expedition, but information ob- tained would indicate that there are still alive a very few of these excessively valuable ani- mals. The natural history collections made by the expedition were large considering that the islands were visited during the dry season. Specimens in various groups were obtained in approximately the following numbers: birds and mammals, 300; reptiles and ‘amphibians, 1,000; insects, 1,100; land shells, 2,000; marine fossils, many; and miscellaneous fishes, inver- tebrates and plants. The representatives of the Mexican govern- ment are thoroughly alive to the necessity of conserving the natural resources of their western territory. It is not expected that measures will be adopted which will throttle SCIENCE [Vou. LVI, No. 1453 the proper commercial development of the vast wealth of marine life of those waters but it is expected that the Mexican government will provide laws and regulations which will prop- erly safeguard and conserve those resources so that they may continue for all time valuable assets of that government. G. Datuas Hanna CALIFORNIA ACADEMY OF SCIENCES AID TO RUSSIAN SCIENTISTS Tue American Committee to Aid Russian Scientists with Scientific Literature made an appeal through Scrence (June 23, 1922) to the scientific men and organizations of the United States for gifts of American scientifie books, journals and papers to be sent, by aid of the generous cooperation of the American Relief Administration, of which Mr. Herbert Hoover is chairman, to Russia for distribution among Russian universities, scientific organiza- tions and individual workers. In addition to the general appeal through Sctmnce, the com- mittee made a special appeal by letter to vari- ous commercial publishing houses, university presses and scientific organizations which pub- lish journals, memoirs, bulletins, ete. The response to this appeal has been wide- spread and generous. Up to date nearly nine tons of American scientific books, journals and papers published since January 1, 1915, have been collected and sent to Russia. The con- tributors include 70 government and_ state bureaus and experiment stations, 40 universi- ties and colleges and university presses, 25 national and state scientific societies and about 120 private individuals. To make special men- tion of any contributors among the many who have made such generous response to the appeal may seem unfair, but to reveal the interesting fact that commercial publishing houses, which are presumably not primarily philanthropic, or, at least, immediately benevolent in their aims, have exhibited a generosity not inferior to that shown by the more strictly science- supporting organizations, I want to call atten- tion to such examples of good will as shown by the Yale University Press in its contribution of six copies each of twenty-four first class. scientific books published by it, and by Double- day, Page and Company in submitting a list NoveMBER 3, 1922] of their publications and requesting the com- mittee to choose what books it desired. The only disappointment to the committee is that caused by the comparatively small number of private individuals so far represented in the list of donors. A partial explanation of this is undoubtedly to be found in the fact that the appeal was issued at just about the end of the academic year when many professors had left their laboratories for their summer vacation. The committee wishes to express its thanks to all those organizations and persons who have responded to its call and to make known to these contributors an expression, recently received by cable, of the great gratitude of the Moscow representative committee of Russian scientists. It also wishes to repeat its appeal to indi- vidual scientifie workers for contributions of reprints to the number of six each, if pos- sible, of their published papers since January 1, 1915. The committee has at its disposal only a limited fund to cover the necessary clerical work.

Con- tributors should send, with each consignment, one copy of a list of the publications sent by them and five copies of this list (apart from the consignment) together with all letters con- taining advices of shipments, express and shipping receipts to the American Relief Ad- ministration, Russian Scientific Aid, 42 Broad- way, New York City.

Re- quests for further information should be sent to the American Committee to Aid Russian Scientists, 1701 Massachusetts Avenue, Wash- ington, D.

The contributed material is not turned over to the Soviet government, nor is the distribution of this material determined by the Soviet govern- ment. The distribution is effected under the SCIENCE 50 Or general direction of the American ‘Committee by the American Relief Administration work- ing in cooperation with a special committee in Moscow of Russian scientists representing various Russian universities and scientific or- ganizations. The extraordinary independence of the American Relief Administration, extra- ordinary in the light of the existent cireum- stances, as regards its activities in Russia, is perhaps not generally realized here in America. Vernon I The case was of a year’s standing, and had been treated unsuccessfully with arsenic, antimony and emetine. Four doses of “205,” making a total of 3.5 grams, were given. A few hours after the first dose the fever disappeared, and a complete cure ap- pears to have been produced, for four months later there were no signs of recurrence of the disease. The drug therefore appears to be a trypano- cidal remedy of ‘the first importance, and the fact that a single dose confers prolonged immu- nity to trypanosomes suggests that it will be of the greatest value as a prophylactic. A com- mission of German doctors is now in Rhodesia testing the drug, and our knowledge as to its action in man will soon be much more exten- sive. The discovery of “205” promises to mark a great advance in tropical medicine, but it is a remarkable fact that England should be de- pendent on Germany for this advance in trop- ical medicine, for at present Germany has not a single colony, while England has the largest tropical empire in the world. It is not a posi- tion of which we have any reason to be proud, but its cause is simple. Germany appreciates the value of pharmacological research and we do not.—Lhe British Medical Journal. SCIENTIFIC BOOKS Smell, Taste and Allied Senses in the Verte- brates. G. H. Parker. Philadelphia and London, J. B. Lippincott Co., 1922, 192 pages, $2.50. This little volume includes chapters on the Nature of Sense Organs, Anatomy of the Olfac- tory Organ, Physiology of Olfaction, Vomero- nasal Organ or Organ of Jacobson, The Com- mon Chemical Sense, Anatomy of the Gusta- tory Organ, Physiology of Gustation, and Interrelation of the Chemical Senses.

Med. and Paras., 479, 15, 1921. 516 attacks upon problems of this sort in the field of sense physiology, it is needless to say that his survey of the chemical senses is accurate, authoritative and judicious. So bref a sum- mary naturally can make no claim to complete- ness, but it is a well balanced selection of topies of significance to students of physiology, psychology and allied sciences. The more theoretical discussions, especially those centering about the genetic relationships of the receptors, naturally enter debatable ter- ritory. In summarizing his well-known ob- servations on the organization of sponges, which “possess muscles but are devoid of ner- yous tissue,” Dr. Parker reiterates (p. 21) his belief that in phylogeny differentiated muscles probably preceded nervous tissue. “So far as ean be judged these [nervous] elements orig- inated in connection with the previously dif- ferentiated muscle and as a special means of exciting it to contraction.” This conclusion seems both unphysiological and unsupported by the facts. That muscle should be differentiated in ad- vance of the receptive apparatus through which it is activated seems a priori as improbable as that receptors should be developed in advance of the appropriate effectors. And Parker’s own experiments strongly suggest that the so- called muscles of sponges are really excito- motor organs with lowered excitation threshold and that the excitation mechanism is elaborated within them parallel with the contractile mechanism rather than apart and subsequently. Ordinary protoplasm is, of course, both excita- ble and contractile, and in some unicellar forms (e. g., Diplodinium, Euplotes, Parame- cium and others recently described at the Uni- versity of California) there are excito-motor masses of protoplasm in which these two func- tions are both highly developed and in various stages of separation physiologically and struc- turally. In sponges, as in other lowly multi- cellular forms, the excitation factor can not be regarded as lagging behind the contractile factor in the differentiation of the process and apparatus of reaction, even though the tissue involved may look more like muscle than like nerve. SCIENCE [Vou. LVI, No. 1453 In the concluding discussion (chapter 8) all receptors are arranged in three groups: (1) mechanicoreceptors (organs of touch, hearing, equilibration, and probably organs of muscle, tendon and joint sensitivity, lateral line organs of fishes and some others); (2) radioreceptors (organs of vision and temperature); (3) chemoreceptors (organs of smell, taste, general chemical sensitivity, and probably some others). This classification is natural and so far as it goes very satisfactory. But when the author adds (p. 180), “To ascertain into which of these three groups a receptor falls it is neces- sary to know how it is stimulated after which its classification is simple and immediate,” one begins to question how far the simplicity and immediacy of the procedure really takes us. Rays of the solar spectrum with wave length of say .0008 mm. falling upon the retina and upon the skin produce very different excita- tions. Both organs are by definition radio- receptors, but just “how it is stimulated” we do not know in either case, nor do we know how it comes about that, if sensation follows the excitation, it is of red in one case and warmth in the other. Similarly, it has been shown by Parker that ethyl alcohol is an excitant of the organ of smell, the organ of taste and general mucous surfaces and by Carlson of the mucous lining of ‘the stomach also. The threshold is different in each of these cases, the typical-reactions are very characteristic in each case, and the sensa- tions (if any) are likewise distinct. Now the fact that these four organs are all chemo- receptors, while important, is less significant biologically than any one of the other three criteria mentioned. In fact, the classification of receptors in terms of the effective stimulus has a very limited range of usefulness and the ultimate goal of our endeavors should be to add to the simple determination of the adequate stimulus of a sense organ the physiologically far more significant knowledge of the real na- ture of the excitation (that is, of the immediate protoplasmic response to the stimulus) and also a codified statement of the typical or physiologically “normal” more remote effects (reaction, sensation). We are at present very NovEMBER 3, 1922] far from the attainment of this ideal, for, as Parker says (p. 180), “The real difficulty lies in the fact that the numerous receptors that we “now recognize have undergone varying degrees of differentiation and hence their mutual affini- ties are extremely diverse.” On the morphological side the difficulties are even greater, and the various attempts which have been made to determine which of the vari- ous anatomical patterns of end-organs are more primitive seem rather futile. Protoplasm in general seems to be sensitive to all of the three kinds of stimuli of Parker’s classification and morphologically homologous organs seem capa- ble of transgressing our artificial ‘biological laws and “uniformities” in fashion most dis- quieting to the systematist. This is illustrated by Whitman’s description (since confirmed by Hachloy) of the cutaneous sensille of leeches, which are tactile in function on the body but in the head become gradually metamorphosed into visual organs, and also by the way in which both olfactory and gustatory organs may serve on occasion as either interoceptors or exteroceptors, with characteristically different — central connections and reaction types in the two cases. No better summary of this phase of the matter can be given than the concluding sen- tences of Parker’s book: “It is because of the repeated differentiations that characterize the evolution not only of the chemoreceptors but of the other groups of like organs that a classi- fication of them or even a simple enumeration proves to be so unsatisfactory. For they are not unitary elements that can be counted like the fingers on the hand nor are they sufficiently co-ordinated to make classifications easy and natural. They are like the whole organism itself in that they exhibit that kind of diversity that characterizes evolutionary flux.” C. Jupson Herrick SPECIAL ARTICLES PERIGENESIS I am presenting here a short preliminary ac- count of the results of a study of the division figures in Tradescantia virginica L. With the methods used, the structure of the SCIENCE 517 chromosome is that of an achromatic cylinder of jelly-like consistency as described by Vejdovsky (1912) in which the chromatin, however, is imbedded in the form of chromo- meres rather than a spiral. These bodies are so distinct that in any one optical plane, they can be counted. They are made up of flocculated chromatin particles which associate together in rather dense masses which are arranged inside of the periphery of the linin cylinder in such a man- ner that there results a central core of achro- matic substance. The relationships of the chromomeres one to the other seem to be somewhat variable although the chromosome often shows a quad- ripartite cross-section as figured by Merriman (1904), Bonnevie (1908), and by Nawaschin (1910). The effect of fixing, imbedding, and staining this structure gives appearances which have doubtless led to the interpretation that it is longitudinally split. The arrangement of the chromatin particles ‘within the achromatie eylinder may be traced back, in the vegetative stages especially, to the earliest prophases and I do not find anywhere, either in the vegetative or reduction divisions, any further evidence of a longitudinal split so that for the reductions, I agree with Meves and others that there is no side by side pairing of the chromosomes in these stages. I find as did Suessenguth (1921), in spite of the recent evidence in favor of a parallel con- jugation, that the continuous prophase spireme is constricted into the chromosomes in end to end relationships. Muller (1921), in diseussing the work of Troland (1917) says, “If he is right, each dif- ferent portion of the gene structure must— like a erystal—attract to itself from the proto- plasm, materials of a similar kind thus mould- ing next to the original gene another structure of similar parts, identically arranged, which then become bound together to form another gene, a replica of the first.” From the’ phenomena in all metaphase fig- ures, inasmuch as I find the separation is not by longitudinal division, I would limit the above quoted process to the stages beginning with 518 the close of the telophase and closing with the first tendency towards the formation of the spireme or, in other words, to the so-called’ resting condition. E. Haeckel described such a process of growth as the perigenesis of the plastidules though perigenesis as described by Haeckel is not referred to by Muller. The sporophyte cell, from the end of the telophase to the beginning of the next pro- phase, would therefore become, normally, a tetraploid unit with the chromatic contents merely in need of distribution in the case of the vegetative division or, in the case of the reduction division, of random segregation. Actual return to the gametophytic condition is not accomplished till the second division since dyads are separated on the first or so-calied heterotypic spindle. It is assumed that the genes after the genesis of itheir like, reassemble in such a fashion that they form a continuous prophase spireme thread. It is during this reassembling of the genes, this reorganization of the nucleus, that the phenomena of crossing over may occur as well as perhaps some mutations not due ito such factors as non-disjunction, re-duplication, deficiency, etc. My material was examined in the living con- dition, by special staining methods of the living cells in sugar suspensions, by intra- vitam staining, and, as a check, by the standard fixing, hardening, and imbedding methods. Detailed descriptions, drawings, and photo- graphs will be published in the near future. Haroup C. Sanps CoLUMBIA UNIVERSITY THE AMERICAN CHEMICAL SOCIETY (Continued) DIVISION OF RUBBER CHEMISTRY C.

The gaseous, liquid and solid decomposition products of zine ethyl xanthogenate are shown to have no accelerating value. The activity of zine ethyl xanthogenate as an accelerator is due to the unchanged molecule. Liffect of certain tread pigments on tempera- ture developed in pneumatic tires: D. F. CRAVER.

Disubstituted guanidines: WINFIELD Scort. Disubsubstituted guanidines function as accelera- tors as amines and belong to the class of hydro- sulfide accelerators only. Diphenylguanidine reacts with hydrogen sulfide and carbon bisulfide to form a trithiocarbonate, with aniline and carbon bisul- fide to form a dithiocarbamate and with carbo- diphenylimide to form tetraphenylbiguanide. The effect of small amounts of zine oxide and zine carbonate on the tensile strength of rubber cured with disubstituted guanidines is quite marked. The relative curing powers of di-p-tolylguanidine, di-o-tolylguanidine and diphenylguanidine are in the order named, the first being the most efficient. It requires 25 per cent. more diphenylguanidine than di-o-tolylguanidine to produce the same ac- celeration. Studies in W. W. Voert. Thermal changes during vulcanization: Ira WaLtiaMs and D. J. Braver. The measnrement of the temperature developed in the center of a cylinder of rubber sulfur mixture which is im- mersed in a constant temperature bath shows that heat is liberated during the first stages of the reaction. An absorption of heat is indicated during the later stages. The extent of these thermal changes has been estimated when stocks of different sulfur and accelerator content were hysteresis of rubber compounds: NovEMBER 3, 1922] eured at different temperatures.

BREYER.- Reactions of accelerators during vulcanization. V. Dithiocarbamates and thiuram disulfides: G. W. Beprorp and Haroitp Gray. The metallic dithiocarbamates are true accelerators of vulcan- ization. Metallic oxides are necessary to prevent the decomposition of the metallic salts by hydro- gen sulfide or to reform them after decomposition. Hydrogen sulfide changes thiuram disulfides to dithiocarbamates and decomposes the metallic salts. Ammonia increases the curing power of both thiurams and zine dithiocarbamates. These views are supported by chemical data obtained in the laboratory in the absence of rubber. A method for the measurement of resistance to tear in vulcanized rubber: ERLE C. ZIMMERMAN. A method is presented for measuring the re- sistance to tear of vuleanized rubber in terms of work. In this test a sheet of rubber 0.1 inch thick is supported between hooks on the ordinary tensile testing machine, and an autographie chart is taken as the rubber is torn. Resistance to tear is expressed as inch-pounds per square inch of rubber torn, in the formula, Fe WE I Lt in which ‘‘K’’ is a constant, ‘‘A’’ is the work area on chart, ‘‘L’’ is the distance torn, ‘‘t’’ is the thickness, ‘‘e’’ and ‘‘F’’ are the elongation and force in equilibrium at the end of the test. Some data are given of resistance to tear in zine oxide and pure gum stocks. The results of variation in the sulfur and hexa- methylenetetramine content on some of the prop- erties of compounded rubber: H. A. DEpEw. A non-blooming compound must not contain more than 1 per cent. of free sulfur calculated on the rubber. Using hexamethylenetetramine as an ac- celerator, the tensile strength, elongation and maximal area under the stress-strain curve increase with a decrease in the amount of sulfur used, and to a lesser extent are increased by using a large amount of accelerator. The shape of the stress-strain curve is not affected by the sulfur and accelerator content. The vuleaniza- tion coefficient at the optimum cure depends on the sulfur content. An abrasion machine by which comparative wear tests can be made-on laboratory test pieces SCIENCE ‘dients in hard rubber: W. E. Guancy. 519 or on sections cut from tire treads: H. A. DEPEW. A simple abrasion machine is described, on which laboratory test pieces or sections cut from tire treads can be tested for comparative resistance to the abrading or rasping influence of surfaces of known composition. The test pieces fastened at one end, only, are held against a common, uniformly moving, abrading surface with a def- inite uniform pressure. The effect of pressure upon the test piece and the effects of speed and composition of the abrading surface are dis- cussed. A comparison of this method of testing with the loose abrasive method is given. Com- parisons by service tests (tires and heels) are also made. The influence of certain compounding ingre- Several articles have been published showing the action of compounding ingredients in soft rubber goods. Very little has been published thus far with re- gard to the principles of hard rubber compound- ing. Graphs are shown which indicate the mass action effect of sulfur, the curing properties of lime and magnesia and the loading qualities of M. R., tire reelaim and resin in hard rubber mix- tures. A convenient nomograph for rubber chemists: W. R. Hickuer and W. E. Guancy. Rubber chemists have frequently use for tables which will be available for converting the cure of a rubber stock from a known temperature and time to a different temperature with corresponding time.. A formula has been worked out from ex- perimental values and a nomograph constructed whereby it is possible to quickly find the desired cure. Rubber softeners: P. M. AuurMan and C. O. Nortu. The action of rubber softeners on rubber itself has received very scant attention from rubber chemists. The writers in an effort to find out this action heated vulcanized rubber in each of a large number of softeners until total disinte- gration ensued. The comparative rate of dis- integration was also observed by means of a test in which the swelling of the rubber in the soft- enérs was measured. This method was checked roughly. Sulfur, accelerators and both together were added successively to the softeners to find out their effect on the action, with the results that in each case there was an increase in the rate of solvation. The state of cure was also found to have'an effect on the results, as the rate of solvation was found: to be inversely pro- portional to the cure. Mixtures of softeners were found to have, in many cases, the average proper- 520 ties of their components. From these and com- pounding results, the writers are of the opinion that a definite relation can be worked out between solvating action and the effects of softeners on the stress-strain curve. The measurement of temperature in rubber articles by means of thermocouples: ELuwoop B. Spear and J. F. Purpy. Measurements of the temperature in rubber articles by thermocouples are all too low where the depth of insertion is not great, 1-3 inches, and where there is at the same time a temperature differential along the buried portion of the thermocouple wires. The correction to be applied depends upon the depth of insertion, the size of the wires constituting the thermocouple, and the temperature differential. A new method is given for measuring the tem+~* perature in pneumatic and solid tires. Correction curves are given for use where ordinary thermo- couples have been employed. The limitations of the obscuring power test for compounding materials: ELLwoop B. Sprar and H. A. Enpres. Experimental evidence is pre- sented in this article that the obscuring power test for compounding materials is unreliable and often misleading in the region where the diameter of the particles is in the neighborhood of one fourth the wave length of light, viz., O.1 mu. The crystallization of sulfur in rubber and the phenomenon of ‘‘blooming.’’? I: Herperr A. Enpres. A solution of sulfur in rubber exhibits the same phenomena of diffusion, crystallization and super-saturation as are shown by solutions of sulfur in other solvents. When rubber saturated with sulfur at calendering or vulcanizing tem- peratures is cooled, the solubility is exceeded and the excess sulfur separates as super-cooled globules, dendrites or stable rhombic crystals, de- pending upon the rate of cooling. Sulfur bloom is always composed of rhombje sulfur; the stable It may be caused by crystallization at the surface of the rubber, either directly from solution or by transformation from super-cooled globules or dendrites. The microscopic examination of rubber com- pounds containing antimony pigments: A. -F. HarpMAN.

A study has -been made of the effects of several compounding pigments upon the abrasion resistance of vul- canized rubber. It was found that gas black gives the greatest resistance to abrasion, followed by light magnesium carbonate, china clay, zine oxide, colloidal barium sulfate and lithopone, in the order named. There is found to be a rela- tionship, but not a direct proportionality, between tensile strength and abrasion resistance for rubber compounded with reinforcing pigments. Resilient energy gives an approximate index of abrasion resistance with gas black, magnesium carbonate, china clay and zine oxide, but it is not a measure of abrasion resistance with colloidal barium sulfate or lithopone. The data appear to show that hardness (or rigidity) is also a factor in resistance to abrasive wear. The product of resilient energy and hardness is suggested as an index of toughness. Some principles are sug- gested which may be of value in compounding rubber to obtain high resistance to abrasion, including the use of high-grade accelerated mix- ings and combinations of reinforcing pigments in such proportions by volume as to give proper rigidity combined with high resilient energy. Combinations of gas black and magnesium car- bonate in suitable proportions are found to give high resistance to abrasion, high resilient energy and considerable hardness and rigidity.

The preparation of mereaptobenzothiazole derivatives by the methods reported in a previous paper has been extended to include several new mercaptothiazoles not previously described. Other compounds hav- ing a similar structure have been prepared and their curing power compared with that of mer- eaptobenzothiazole. In this way the particular grouping responsible for the activity of mercapto- benzothiazole as an accelerator has been identi- fied. The effect of substitutents in the benzene nucleus of mercaptobenzothiazole upon its activity as an accelerator has also been studied. Cuares L.

CHAMBERLAIN, B.S., A.M., of the Faculty Drexel Evening School, Philadelphia. The text is free from hair-splitting theoretical distinctions, and detailed descriptions of mechanical or electrical devices which properly belong to advanced engineering. Characteristic features are the conciseness of treatment of fundamental principles, with special reference to their application to engineering; the solution of illustrative problems, and the large number of practical problems, mostly new, submitted for solution by the student. Some special features are—a simple and practical chapter on meastirements, errors, ac- curacy and precision and significant figure,—fundamental subjects not often introduced out- side technical books—involving advanced mathematics: a general treatment of physical com- putations, principles and methods of curve plotting and use of vectors, with applications later. as the need arises; logical treatment of Mechanics under the headings of Kinematics, Dy- namics and Statics. The chapter on Electrostatics has been reduced to the minimum amount required to familiarize the student with such ideas as “Potential,” “capacity” and other fun- damental conceptions. Insistence upon the distinctiori between potential difference and elec- tromotive force. This distinction has been found by the author, in common with others who have insisted upon the same discrimination, to aid in preventing confusion, especially when the student considers the potential difference at the terminals of a battery, a dynamo, or a motor. Attention is called, all through, to the fact that all formulas are merely mathematical ex- pressions of definitions or laws, true under certain stated conditions. If these conditions be observed “theory and practice” must always agree. BRUBAKER—Textbook of Human Physiology = ““""" Revised. Enlarged. 367 Illustrations. Cloth, $4.75. By Ausert P.

No attempt will be made in this sketch to do more than to give the briefest outline of historical facts. The extent to which the water of Colorado River is being used for irrigation will appear from the following figures compiled by Mr. H. C. LaRue for 1913. Colorado; area irrigated in 1913 was acres. Wyoming; area irrigated in 1913 was 280,000 acres. Utah; area irrigated in 1913 was acres. Nevada; area irrigated in 1913 was 5,000 acres. : New Mexico; area irrigated in 1913 was 40,000 acres. : Arizona; area irrigated in 1913 was 315,000 acres. California; area irrigated in 1913 was 297,000 acres. Mexico ; acres. 440,000 204,000 area irrigated in 1913 was 50,000 In California the irrigated area now ap- proaches 500,000 acres and in Mexico it is about 190,000 acres. There has, of course, also, been extension of irrigation in the upper states but later figures are not at hand. No Colorado River water was used for ir- rigation in Mexico prior to the construction of the Imperial Canal from which water began to be used in 1901. By 1905 there were about 5,000 acres of land in Lower California being irrigated. In 1910 the area was probably about 20,000 acres and in 1920 had reached about 150,000 acres. The potential use of water from this river and its tributaries can not be stated with any great degree of precision. Some allowances must be made for the fact that just at present each of the several interested states is endeavor- ing to secure recognition of extreme ultimate possibilities in this connection rather than of early future probabilities. For the purpose of "a guide in this discussion the following figures ave noted—the endeavor being to include in the areas noted as irrigable only such as would seem to justify construction of works within the next thirty years. Jn the Green River Basin the extent of ir- rigation in 1913 was about 500,000 acres and SCIENCE [Vou. LVI, No. 1454 expansion within thirty years to about 900,000 acres is to be expected; in the Grand River Basin from about 300,000 to about 420,000 acres; on the lower Colorado from about 400,000 acres to 1,500,000 acres; in the Gila River Basin from 280,000 to some uncertain extent possibly 400,000 acres; in the San Juan River Basin from 117,000 to 500,000 acres; in the basins of the lesser tributaries of Colorado. River from about 61,000 acres in 1913 to about 160,000 acres, and in Mexico from 50,000 in 1913 and 190,000 in 1921 to 600,000 acres. After the war between the United States and Mexico the boundary line between the two countries had to be fixed. This was done in a conference resulting in a boundary line treaty consummated in 1848. But it was soon found that portions of the line westerly from the Rio Grande should have been placed further south and negotiations were commenced for a modifi- cation of the line. The result of these negotia- tions (in 1853) was the acquisition of a strip of land, now the south portion of New Mexico. and Arizona known as the Gadsden Purchase. There is a story current, though probably im- possible of verification and to be considered for the present as without foundation in fact, to the effect that the Commissioners of the United States who made the purchase were given the choice of three locations for a new line. According to this story the line furthest to the south touches the head of the Gulf; but the payments to be made by the United States: to Mexico were graded according to the dis- tance that the boundary would be shifted south- ward and the line requiring the least payment was selected by the United States Commission- ers. Whether this story be true or not we can now see how unfortunate it was to have fixed the line in its established position. It should have been as far south as the head of the Gulf of California so that the entire delta of the Colorado River would have been in the United States. The Commissioners accepted a loca- tion of the line which may at any time become a source of friction and which has already be- come a matter of great inconvenience and some embarrassment to the United States. The boundary divides the delta of the river not along a channel, which would be bad enough, but in such a way that most of the delta slope NovEMBER 10, 1922] toward the south and some of the slope toward the north remains in Mexico. — The absurdity of the resulting situation is daily becoming more apparent and the inter- ruption of diplomatic relations with Mexico (from 1913 to date) has thus far prevented the taking of steps to ameliorate a situation, involving river work in Mexico for the joint benefit of the two countries, which is fast be- coming intolerable. It may be remarked, too, that the seriousness of the situation and the im- portance of having adequate control of the delta section of the river vested in some agency which can accomplish results is not generally recognized. Recall for a clearer understanding of this international political matter the essential physical facts: The Colorado River was found on a course to the Gulf of California 400 years ago by Spanish explorers. a dry Salton Basin. required to evaporate the water from this basin after the river ceased to discharge into it, there is, therefore, positive evidence that for over 450 years and probably for over 500 years the Colorado River has been flowing down the south slope of its delta cone. There is physi- cal evidence, too, easily read, that in recent geological time the river has repeatedly changed its point of outfall from the Gulf to the Basin and back again to the Gulf. The following reference to the Salton Basin is found in the report of G. W. Blake, geologist of the trans- continental railroad survey, 1853: These explorers, too, found As about 50 years were “The present outflows, though but very slight, are probably similar (referring to In- dian traditions of a great flood), and yet it is possible that the interior of the desert might be deluged at the present day, provided no elevation of the Iand has taken place and the river should remain at a great height for a long time—long enough to cause the excavation of a deep channel for New River.” The Indian tradition relating to the ancient lake is thus given by Dr. Blake: “The great water (agua Grande) covered the whole valley and was filled with fine fish. There were also plenty of ducks and geese. Their fathers lived in the mountains and used SCIENCE 0235 to come down to the lake to fish and hunt. The water gradually subsided “poco poco” (little by little) and their villages were moved down from the mountains into the valley it had left. They also said that the waters once returned very suddenly and overwhelmed many of their people and drove the rest back into the mountains.” This aneient lake had a total length from northwest to southeast of 100 miles. Its northern limit was several miles above Indic and its southern margin was 15 miles south of the international boundary in Mexico. It has a mean width of 20 miles. The evaporation of this great body of water, after inflow ceased, caused the mineral contents of the water to be gradually carried to the lowest portion of the basin, where a crust of salts, mainly common. salt, was left in sufficient quantity and of suf- ficient value to justify the establishment of salt works, which were operated for some years by the New Liverpool Salt Company. {t is within the area once covered by the an- cient lake that all of the improved area of Im- perial Valley lies. Calexico, at the Mexican boundary, is at sea level. Imperial, 12 miles farther north, is about 60 feet below sea level, and the cultivated lands near Brawley extend from about 100 to 200 feet below sea level. ' At the northern end of the basin is Coachella Valley with Indio farthest north, and Mecca 190 feet below sea-level near the shore of the lake, when the lake was at its greatest extent in February, 1907. And then there was another Indian tradi- tion to the effect that the Colorado River flowed into a hole in the ground. The explanation of this tradition oecurred to the author of this paper a few years ago and seems simple enough. When the Salton Sea was full, its surface extent was about 2,000 square miles. From this large area of water the annual evaporation was nearly 8,000,000 acre feet of water. This is one half of the normal annual discharge of Colorado River and more than the river’s discharge in a year of light run-off. There were, therefore, probably periods of time sometimes exceeding a year in duration, aside from the filling period, when the Indian saw a river flowing into Salton Basin and saw no 924 water flowing out from this basin. What more natural than that he should assume a hole in the ground through which the river poured its waters into the bowels of the earth? But of particular interest, because of its bearing upon the present discussion, is the main fact that periodically, say for a period ot 500 to 1,000 years, the Colorado River had an outfall into the Salton Basin, that is, down the northern slope of its delta cone and again for a similar period of time the river has dis- charged into the ocean through the Gulf of California. With this fact in mind let the boundary line be traced from the south boundary of Arizona following up the Colorado River for some 20 miles to Pilot Knob, and thence a little south of west in a straight line to the Pacifie Ocean. This boundary line leaves a part of the Colo- vado River delta, Yuma Valley, in Arizona. It leaves the head of the Gulf of California and the main south slope of the river’s delta cone in Mexico; and it leaves the major por- tion of the north slope of the delta cone, in- cluding what is now known as Imperial Valley and also the Coachella Valley, which was once deep under. the waters of the ancient sea, in California. From the earliest studies made of this re- gion by citizens of the United States it is known that the Colorado River originally flowed from near Yuma to the Gulf of Cali- fornia in a meandering channel, having un- stable banks, and inadequate capacity to carry all the water presented at flood stages. The distance in an air line from the head of the river’s delia to the Gulf is in round figures 80 miles. In this distance the river falls 100 feet. It is about the same distance from the head of the delta to the lowest portions of Salton Basin but as the lowest part of the basin is over 280 feet below sea-level the fall in this «lirection is nearly 400 feet. If the river should be permitted to flow into the basin it would take 20 or 30 years to fill it up. There was no immediate danger of the river making a change in its course under the natural conditions that prevailed 50 to 75 years ago ‘because at each flood stage the river banks were overtopped; they were well watered far back from the edge of the stream, and carried a luxuriant growth SCIENCE [Vou. LVI, No. 1454 of trees, brush and grass and they were being constantly warped up by the sediment which the muddy water of the river spread out over the land. But as soon as human activities modified these natural conditions, as soon as a small dredger cut invited the river down the steep northern delta slope, the river broke from its channel and temporarily abandoned its course to the Gulf. This happened in 1905 and it took a little more than a year to put the river back into its old channel. But while this was being accomplished the delta channels went dvy. The vegetation on the parched bank land died out and fire destroyed the plant growth in large part which had, theretofore, protected the area nearest the river against erosion. And so, at the subsequent high stages of the river, there Was more overbank flow and greater concentra- tion of water in the swales leading away from the river and therefore increased danger of the river breaking out of its original channel. 1907 and 1908 passed without this happening, \but in 1909 the river broke a new channel toward the west following the course of what was known as the Rio Abejas or Bee River. The point where this abandonment of the original river channel occurred was about opposite the south boundary line of Arizona. The river has ever since, except for a fer weeks while checked by a levee, been sending its water southwesterly in a round about way, through Voleano Lake and the Hardy Colo- rado into the Gulf. But its flow westerly was on or near the erest line of the river’s very flat delta cone. Its channel is a broad shallow bed of sand of irregular alignment. At flood stages its water submerges ‘broad stretches of country. Its flood waters would preferably drop off the delta cone to the north ‘but have been prevented from doing this by levees. Herein lies the purpose of this statement of physical facts. The levees along the river and along the crest of its delta were and are re- quired for the protection of property in the United States. All of Imperial Valley and of Coachella Valley are menaced. This does not mean that if a breach in the levees occurred and the river again discharged into Salton Basin that all of these valleys would be flood swept. Not at all. The river would simply WoveMBER 10, 1922] flow for a time into Salton Sea doing some damage but it would be turned back again toward the Gulf long before it could make any great headway toward filling the basin. The interesting fact is that the levees which wrevent the river from thus turning to the north and the great undertakings in 1906 and 1907 of turning the river from an erratic course back into its old bed, had to be done in foreign territory, and, moreover, without per- mission or sanetion to do the work by any treaty arrangement. This will be explained by going back a little. When the Colorado River Land and Water Company (after reorganiza- tion the California Development Company) determined to put Colorado River water upon California lands it acquired a large tract of land in Lower California just south of and paralleling the boundary line. It organized in Mexico a subsidiary company, the “Compania de Terrenos y Riegos” and through the agency of this company constructed a few miles of canal from the boundary line, near the river, * southerly and southwesterly, to a connection with a flood water slough known as Carters, or Salton or Alamo River. Meanwhile a di- verting canal was constructed in California tapping Colorado River a few hundred yards north of the boundary line and leading into the upper end of the Mexican Canal. When water was turned into the canal in California it flowed to the Mexican Canal and thence to the Alamo channel and thence back into Cali- fernia, This became the nucleus of the Im- pevial Canal system. However, after a few years there was trouble at the head of the canal. Its upper section was too flat to pass all the silt entering from the river. And so in 1904 the Mexican Corporation made appli- cation to the Mexican Government for a water coneession and the right to construet and main- fain canals in Mexico. This was granted and provides that water may be diverted from the Colorado River in Mexico or may be brought into Mexico from California and conveyed across Mexican territory back into California, subject, however, to the condition that, to the extent of one half of the water in the canal, the landowners of Mexico shall have the right to use this water for irrigation. SCIENCE 525 When Imperial Irrigation District was or- ganized and acquired the canal system of the California Development Company, it accepted the same subject to the conditions of the Mexi- can concession and for the purpose of doing work in Mexico it operates through its sub- sidiary, the Mexican Corporation. It will ‘be recalled that in 1909 when the Colorado broke from its channel into Bee River the Congress of the United States appropriated $1,000,000 to be used in protecting the Salton Basin against ultimate submersion. The Colo- rado River was to be turned back into its old bed and held there. As there was no treaty for the contemplated operations in Mexico, the President designated Mr. J. A. Ockerson to undertake the work. He in turn made the Mexican Corporation his agent and the work went on.. It included not only the turning of the river but also the enlargement and exten- sion of the levee north of Voleano Lake which has since become an increasingly important line of defense for the Imperial Valley. When it is now considered that the control of the floods of the Lower Colorado will benefit about 800,000 acres of delta lands in Mexico and a somewhat larger area in California,— much of this, however, still in wild unimproved condition—the faet will be realized that there should be friendly consultation and coopera- tion between the United States and Mexico in order that the control of the lower river which must be put in a direct course to the Gulf and which must be kept there, may be placed in the hands of a competent agency, preferably the United States, and that arrangements may be made for reducing the flood menace by storing the waters of the Colorado at some point such as Boulder Canyon. And then there is needed, too, some under- standing between the two countries as to the quantity of water which will be allowed to flow into Mexico. It is probable that under regula- tion of stream flow by storage there will be enough water for all the lands in the two coun- tries which may reasonably expect it. But practically all of the water which flows in the Colorado River originates in the United States and if the United States should choose to do so and physical conditions permitted, all of 926 the water could be withdrawn from the river for use within the United States. This will never happen, but negotiations in relation to this matter of giving definiteness to what Mexi- «o may expect have already been too long de- ferred. Not only is this the situation with reference to the irrigation use of water but immediate action in the matter of flood control is of para- mount importance. On this phase of the prob- Jem only a word more need be said. Ever since the river changed its course in 1909 it has been depositing its load of silt, about 112,000 acre feet per year, in the Voleano Lake ‘re- gion. Drift and silt have filled depressions and choked old drainage channels. The first effect of the river’s change in alignment was to depress the river’s flood plane at the head of the Bee River six or seven feet and thence up- stream by Yuma. decreasing amounts to and above But as the years rolled by and the warping up of the Voleano Lake regions has continued, the flood plane has been at a mean rate of about one foot per annum. Where no levee was required before 1908, to the north of the site of the lake (the lake itself has already been filled up with silt and obliterated) there is now a levee 14 feet high, with a railroad on top and with its water slope well faced with rock. And yet last year, 1921, the water at some points rose to the top of this levee. At- tempt is now being made to coax the river into a more southerly course, but, even it this should sueceed, the outfall of the flood waters will then be on a broad flat area which will quickly be filled to delta crest elevation and the same problem as the one of to-day will remain to be solved. The solution of this problem as already stated is comparatively simple when physical elements alone are considered. It is the international aspect which renders it com- plex. Action, at once, I repeat, by the United States is imperative. It may ‘be noted in this connection that about 70,000 people live in the area which is to be protected. Property values of $100,000,000 to $200,000,000 are involved. There are several hundred miles of railroads within the area that must be protected against the floods of the Colorado River. SCIENCE [Vou. LVI, No. 1454 In the matter of developing and putting to beneficial use the water resources of the Colo- vado River, it seems self-evident that the great- est ultimate good should be the main considera- tion. State lines cut but little figure in this matter. Opportunity by any state to divert and deprive earlier down-stream users of their water can carry no right to do so unless this be plainly in the public interest and unless it ibe done with due compensation for property values that are thereby destroyed. It is wise, therefore, that steps have jbeen taken for discussion of the river’s problem as it affects the seven states within which the The Colorado River Commission is the medium for bringing these states into conference. What the outcome of this conference will be remains to ‘be seen. Fortunately the production of water in the watershed of the river is so great that, despite waters of the river originate. all that can be done on its ‘headwaters, to hold back and use the water locally, there will . still enough water get by to make the storage on the lower river and the.extension of irrigation in Arizona, California and Mexico desirable and economically feasible. The development on the lower river is an’ interstate and international matter. It should ‘be undertaken iby the United States. The con- trol of such a reservoir as that which is pro- posed for the Boulder Canyon site, for ex- ample, should never be relinquished to private interests whatever the agency by which the project is carried out. Boulder Canyon dam- site is located on Colorado River just above the point where the river makes its abrupt turn from a westerly to a southerly course. It is some 60 miles in an air line above the point where California’s east boundary line strikes the river and is but a few miles below the mouth of Virgin River. The Colorado River at this point forms the boundary between Nevada on the north and Arizona on the south. The canyon is narrow, being generally report- ed as about 250 feet in width for a distance of one half mile. The sides of the gorge are steep. The rock is granite. The project for storage at this site as now favored by the United States Reclamation Service involves the construction of a dam that would rise to a height of about NovEMBER 10, 1922 550 feet above the water surface of the river. The storage capacity of the reservoir to be ‘ereated ‘by such a dam would be in excess of 25,000,000 acre feet. The discharge of Colo- yvado River at this point may be noted, in, ap- proximate figures, as ranging from 7,000,000 to 22,000,000 acre feet per year. The mean annual discharge may be about 15,000,000 acre feet. The surface area of the reservoir would reach 125,000 acres. The feasibility of a dam of the dimensions proposed seems now to be generally accepted by the engineers who have investigated the dam site. A reservoir at Boulder Canyon would control the flow of Colorado River except the contributions by the Gila River, and the stor- age could be so manipulated that it would eliminate the lower river flood menace to the extent that this menace is due to up river high stages. Such a reservoir would also regulate the flow of the river for irrigation purposes, thereby permitting the extension of the ir- rvigated area, and would generate upward of 600,000 horse power for electrical transmission. It is not enough to know that this reservoir should be constructed. Equally important is the matter of urgency. And this applies with equal force to the reservoir control of the river and to the placing of the lower river upon a ‘direct course to the Gulf. C. HE. Grunsky PROGRESS IN POLYNESIAN RESEARCH In view of the many inquiries regarding the status of the anthropological studies in Poly- nesia, undertaken by the Bishop Museum, a summary statement of progress and results ap- pears to be appropriate. Systematic investigations of the origin and culture of the Polynesian peoples have been condueted by the Bayard, Dominick Expedition and made possible by a generous gift of Bay- ard Dominick, Jr., of New York—funds given to Yale University and placed by the university at the disposal of Bishop Museum. During the summer of 1920 four field parties began their work—the first in Tonga, the second in the Marquesas, the third in Rurutu, Raivaivai, Tubuai and Rapa of the Austral Islands, the SCIENCE ‘ 527 fourth in selected islands of the Hawatian group. Through cooperative arrangements with scientists of New Zealand, physical meas- urements of the Maori and a complete survey of the Maoriori of Chatham Tslands forms part of the program. By the end of this year all the field parties will have returned to Hono- lulu. These surveys supplemented by investi- gations in Tahiti and adjacent islands organ- ized for 1923, will complete the present plans of the Bayard Dominick Wxpedition. Con- tributions to the physical anthropology of Samoa and of Tonga have been published by the museum; other papers are in press or in preparation for publication. The prosecution of this search for Polynesian origins aims at the solution of two distinct problems: (1) the souree of the physical racial characteristics, which have combined to make the Polynesian physical types; and (2) the source of ‘the original elements which formed the basis of the ancient culture of the people. Dependent upon the solution of these is a third problem: the degree in which racial and cul- tural transplantation and stratification are cor- related. Dr. Louis R. Sullivan, physical anthropolo- gist of the American Museum of Natural His- tory, is devoting himself to the study of the racial data secured by himself and by other members of the expedition. He makes the fol- lowing tentative classification of the physical characters which go to make up the two basic elements in the Polynesian peoples: Type 1 is characterized by (1) tall stature, (2) moderately long heads, (3) relatively high, narrow faces, (4) relatively high, narrow noses, (5) straight or wavy black hair of medium texture, (6) well-developed moustache and moderate beard on the chin, (7) moderate amount of hair on the body and limbs, (8) light brown skin, (9) incisor rim present occa- sionally, (10) femur flattened (platymeric), (11) tibia flattened (platyenemic), (12) ulna flattened (platolenic), (13) dips above average in thickness. Type I is the so-called ‘Caucasoid element in Polynesia; sometimes spoken of as Pseudo-Caucasian or Psendo-Mediterranean. Maemillan Brown regards it as Nordic. In its characteristics it is intermediate between some 528 Caucasians and some Mongols. It may eventu- ally prove to be a very primitive Caneasoid type, probably related to primitive inhabitants of Micronesia, Indonesia, and to the Aino and some of the primitive American Indians. It is probably the oldest type in Polynesia (except where it was possibly preceded by the Melanc- siams), and it oceupied all of the Polynesian Islands. At present it seems to be strongest in the southern part of Polynesia. Type II is characterized by (1) shorter stature, (2) shorter heads, (3) low, broad faces, (4) low, broad noses, (5) wavier hair, (6) undeveloped beard, (7) body hair rare ex- cept on the legs, (8) darker brown skin, (9) incisor rim rare, (10), (11), (12) long bones less flattened (data meager, results inferred), (13) lips well above the average in thickness. Type Il is the element so often referred to as Malay, and is undoubtedly the one which has been traced to the region of the Celebes by linguists and ethnologists. Malay is not a suitable name for it, since it is usually restrict- ed to groups more definitely Mongoloid. It ap- proaches somewhat closely Giuffrida-Ruggeri’s Indonesian type. This element has contributed some of the negroid characteristics (full lips, dark skin, broad flat noses), usually attributed to Melanesian mixture. The type is strongest in northern and central Polynesia. Edward $8. Handy, ethnologist of the Bishop Museum staff, and a member of the Dominick Expedition to Tahiti and the Marquesas in 1920-21, has come to the following conclusions with regard to the general ethnology of Poly- nesia. There is a basie Polynesian cultural complex, some of the most important elements in which are: (1) cooking by means of heated stones in ground ovens; (2) the use of stone pestles for pounding food; (3) the use of wood, gourd, and cocoanut shell, rather than pottery, for containers; (4) skillful woodworking and carving; (5) tattooing; (6) the making of tapa, or bark cloth; (7) a characteristic rela- tionship system; (8) the customs of adopting and betrothing children; (9) systematie agri- culture and fishing, taro and potato cultures; (10) professional eraftsmanship and leader- ship in industry; (11) tribal government of simple patriarchal communism; (12) presery- SCIENCE [Vou. LVI, No. 1454. ing heads of enemies as trophies, and canni- balism; (13) ancestor worship, the preserva- tion of genealogies, and the hiding of skeletat remains; (14) inspirational diviners; (15) a speculative creation mythology conceived on, the principle of dualism, expressed in terms of male and female agencies. This complex was. universally distributed throughout Polynesia: but it is most clearly to be distinguished in the historie culiuves of New Zealand and the Mar- quesas, both of which groups may be charac- terized as outposts. These elements being uni- versal, and sbest preserved in the marginal region, may be taken to represent the prunitive,, in the sense of original, Polynesian eculture.. This we may call Culture A. Superimposed on this original culture are. certain other elements, some of the most im- portant of which are: (1) organized govern~ ment; (2) a wigid social classification; (3): complicated systems of land division and own- ership; (4) great sacredness of chiefs and elaborate etiquette; (5) organized dancing as a social and religious institution; (6) organized yeligious ceremonial and priesthood; (7) a generation cult and seasonal rites; (8) haru- spication. As compared with Culture A, this. culture appears to have been characterized by- a higher social and religious, rather than higher technical, development. This group, with other: associated elements, too numerous to include. here, may be called Culture B. t is possible that the elements in Culiure B. may have resulted by a natural evolution from the primitive Culture A. But it is far more provable that they represent the culture of a second immigrating wave of a people, closely related culturally to those of the first wave. Churehill’s analysis of the language led him to. the conclusion that the dialect spoken by the second wave of migrators to Tonga and Samoa was very closely related to that of the original settlers. A study of Polynesian ethnology recently completed by Ralph Linton indicates ‘that the — material culture of the Marquesans and re- lated groups suppont entirely the theory of an, original culture and later overlay. important elements which his study adds to the classification given by Dr. Handy are: to Culture A, (1) a rectangular house with en& The’ more Novemsrr 10, 1922] posts and bed-space; (2) a canoe made of five parts; and (3) the tanged adze; to Culture B, (1) the oval house; and (2) wooden head rests and utensils with legs. It is interesting to note that the basal Poly- nesian physical type (Type I), as worked out by Sullivan, is universally distributed, but strongest in the south, and the original culture (Culture A), also universally distributed, is clearest in the south (New Zealand) and east (the Marquesas). Also physical Type II is strongest in north and central Polynesia, the same region in which elements in Culture B are dominant. This demonstrated parallelism of racial types and cultural stratification rests on conclusions arrived at independently by members of the museum staff working in widely separated fields with no opportunity for con- sultation. It is regarded as a very important contribution to the attack on the Polynesian problem. Another contribution is the defini- tion of characteristics and elements belonging to the respective types and cultures—a pre- requisite to comparative studies. As regards the sources of these racial types and cultural elements and the routes by which they came to Polynesia, the evidence in hand indicates the region of the Malay archipeiago (Indonesia) and southeast Asia as that from which the Polynesian ancestors commenced their eastward drift. Whither, beyond that region the search for ultimate origims may jead, ean not be foreseen. The writing of the earliest chapters in the history of the Poly- nesians and of other Pacifie races must await the definition of ancient and modern Asiatic types and cultures and the determination of early stages revealed through archeology. The work of the acheologists of the Bayard Dominick Expeditions revealed no very ancient human habitation in the central and south Pacific. For the Polynesian settlement the evi- dence serves to substantiate the conclusions of William Churehill, based on linguistie and cul- tural study. The following dates are consid- ered reasonable estimates: A.D. 0, the first Polynesian migratory movement; A.D. 600, a second migration; and A.D. 1000, a period of great Polynesian expansion. According to 8. Perey Smith and other Maori scholars, New SCIENCE 529 Zealand was already in possession of original settlers by the tenth century although the main Maori migration did not occur until the thir- teenth and fourteenth centuries. Dr. Handy has concluded that the Marquesas Islands were first settled in the tenth century or slightly earlier, and Fornander presents good reasons for the belief that the original settlers of Hawaii experienced the coming of a migratory wave at the beginning of the eleventh century. At least three general routes of migration appear to have ‘been used through Indonesia: (1) along the coasts of New Guinea, (2) ‘through Micronesia, (3) through and along the marginal region east of Melanesia. Two years of organized study has shown that the history of Polynesia is fundamentally a field problem and that progress depends upon the accumulation of facts by trained stu- dents. Herpert EK. GREGORY, Director BrErnicE P. Bishop MusEuM SCIENTIFIC EVENTS A FOREST UNDER THE CITY OF WASH- INGTON Evinence of ‘the existence of an ancient swamp in which great trees flourished in days long past, possibly contemporaneous with earliest man in America, has been discov- ered in a deep excavation made for the founda- tion of a hotel under construction in Washing- ton, D. C. Alt a depth of about twenty-five feet below the street level the excavation dis- closed a layer of black swamp muck, contain- ing large quantities of wood, tree trunks and stumps. Some of the stumps are of great size, a few of them reaching a diameter of nine or ten feet. Much of the wood is well preserved, showing clearly the woody structure and the external markings of the bark. A preliminary examination indicates that one of ‘the more common ‘trees of this ancient swamp ‘was eypress. The story of ithese \trees, however, is only a brief chapter of the whole geologic history shown in the excavation, which has just ‘been examined by Chester K. Wentworth for the 530 United States Geological Survey. Ages ago this part of the Atlantic Coastal Plain was from time ito time covered by ithe sea, into which streams swept vast quantities of mud, sand and gravel and boulders which formed thick deposits that covered large areas. When ithe region finally emerged from ‘the sea the Potomac River cut its valley in these deposits, which were carried about here and ithere also by smaller streams. The larger boulders are de- rived from the granite on which the gravel lies, but some of ithe smaller pebbles come from parts of the Potomac basin beyond the Blue Ridge and olthers from veins of quartz in the granites of the Piedmont Plateau. Over the layer of plant débris and muck in this old swamp fine clay and pebbles were laid down {by streams of water during the glacial epoch, when (the northern part of North America, as far south as northern Pennsyl- vania, was covered with immense sheets of thick ice, showing that ithe trees lived in the latter part of the Grealt Ice Age, which is vari- ously estimated to have ended from 20,000 to 30,000 years ago. OPPOSITION TO EVOLUTION IN MINNESOTA Ir was reported in Scrence last week that at a conference in St. Paul, Minn., of pastors representing Baptist, Congregational, Presby- terian and Lutheran churches, it was decided to issue a call for a state-wide meeting of Protestant ministers to oppose the teaching of evolution in the public schools of Minnesota. At this meeting, which was held on October 26, the following resolutions were passed: Preamble—As American citizens we believe in the complete separation of church and state, and are opposed to publie schools—higher or lower. As those. who wish to teach Christianity must support their private schools, we believe it but just that those who wish to teach anti-Christian theories should be forbidden the use of tax sup- religious ‘teaching in ported schools for propagating their opinions. Whereas, The evolutionary hypothesis has come to be accepted by many American teachers, and is increasingly taught in the public schools of Minne- sota, including high schools, our state normals and state university, and SCIENCE [ Vou. LVI, No. 1454 Whereas, This hypothesis, after sixty-three years of study, remains wholly unproven, and has increasingly shown itself to be a foe to the Christian faith, denying as it does the veracity of the Scriptures, Therefore be it resolved, That we, citizens of Minnesota, representing thousands of our fellow citizens, hereby utter our protest against this propaganda of infidelity,.palmed off in tthe name of science, and we call upon the trustees of state institutions to demand of teachers a cessation of such teaching and the removal from our schools of such text-books as favorably present the same. We do this in the interest of true science vs. science falsely so-called; and in the interest of fair dealing. ° We hold that the first amendment to the con- stitution of the United States, ‘‘Congress shall make no law respecting an establishment of reli- gion,’’ was never intended to be interpreted that the state should become sponsor for irreligion; and that it is manifestly unfair to impose taxes upon Christian taxpayers to inculeate teaching inimical to the Bible and destructive of civiliza- tion itself. We have waited patiently for this hypothesis to either prove a truth or to pass from public in- struction. Having now no prospect of either, we demand that the state shall prove its impartiality toward its citizens by dispensing with a subject that is utterly divisive; and is, in the judgment of thousands of its taxpayers, utterly false. And we declare that if the school authorities prove derelict in the enforcement of the law re- lating to the teaching of religion or of theories subversive of the Christian faith, we will appeal to the legislature for the enactment of such laws as shall eliminate from our tax-supported school system this antiscientifie and antiscriptural theory of the origin of man and the universe. THE ADMINISTRATION OF THE UNITED STATES GEOLOGIC SURVEY On November 15, David White completes ten years service as chief geologist. This con- tribution to \the administration of the survey has been at the expense of his own scientific work, even though he has thereby increased the scientific value of the work of his associates. Tt scems fair that his oft-repeated request for permission to return to his own geological studies should now be granted, not only te gratify the natural desire of an investigator November 10, 1922 who has laid aside research problems, one after another, but also to promote the advancement of our science. Effective November 16, W. C. Mendenhall, for more than ten years the geologist in charge of the Lang Classification Board, will be chief geologist. Mr. Mendenhall’s twenty-eight years service in the Survey as assistant geolo- gist and geologist, with field experience ex- tending from the Southern Appalachians to Alaska, is a promise of his broad sympathy with all the problems tthat will come under his direction, and his notable success in using the data contiibuied by ‘the field branches in the classification of the public-lands is equally a promise of effective administration. Mr. Mendenhall will be succeeded as chief of the Land Classification Board by Herman Stabler, his close associate in that branch during the past decade. Mr. Stabler’s demon- strated capacity both in research and in admin- istration assures the continuance of the suc- cessful application of geologic and engineering facts and principles to public land adminis- tration. The return of Mr. White to productive re- search suggests anew the sacrifice involved in the administration of scientific work. Admin- istration by scientists is the key-note of the Survey’s policy, yet the intellectual cost item involved in this drafting of our ‘best investiga- tors must be kept down to a minimum. Had I been free from other demands on my time this past summer, I should have ltaken this occasion to start a somewhat radical reorgan- ization of the Geologic Branch, the chief pur- pose of which would be to reduce its adminis- trative overhead—too many geologists are giv- ing valuable time to work for which they were not trained. Necessarily now, this task of sim- plifying the organization must be left to the new chief geologist and the acting director, but I ask for them a sympathetic acceptance of the proposal for a less elaborate but more elastic grouping of the activities of the branch. Not machinery but product is the measure of eft- ciency in a government scientific bureau. Go. Oris Smiru, Director SCIENCE 531 THE NEW BUILDING OF THE NATIONAL. ACADEMY OF SCIENCES AND THE NATIONAL RESEARCH COUNCIL On the afternoon of Monday, October 30,, the cornerstone was laid of the new building of the National Academy of Sciences and of the National Research Council at Washington, D. C.. This building, construction of which has now been carried above the main floor, oceupies a. desirable location upon an entire block of land. north of the Lincoln Memorial at the western. end of the Mall, commanding an excellent and permanent view of the Memorial, the Riverside: Park and the bank of the Potomac beyond.. The land for this building was purchased. through contributions from a group of twenty- friends of science. The building is designed for two main pur-- poses: To house ithe offices of the two organ- izations for which it is erected, and to provide: space for the exhibition of materials repre-- senting certain of the great achievements of° science in the past and especially of recent contributions of particular significance in the: progress of science. The building presents a. fagade to the southward 260 feet in length, and. will rise to a height of 60 feet above the first floor. In this section there will be three floors. for offices, library and special exhibits rooms.. Behind this will be a rotunda for general ex- hibition purposes which will be convertible at need into a lecture room accommodating, with. its galleries, over 400 people. The plans per-- mit ‘the addition of other units similar to the southern facade, to complete a quadrangle around the rotunda. The building is being: faced with white Dover marble of fine quality and color which makes it in keeping with the ~ other monumental buildings of ‘the city. The- cost of the unit at present under eonstruction. will be over $1,000,000. The funds for the erection of the building were provided by the: Carnegie Corporation of New York. The laying of the cornerstone was ‘a ceremony of the simplest kind without ‘the presentation. of any addresses. It was attended by officers. and members of the academy and of the Re- search Council, among whom was the Honor- able Herbert Hoover, secretary of commerce... 532 The stone, itself, bearing the date “1922” and the initials “N. A. S.” and “N. R. C.,” occupies a position high in the wall of ithe first story at the southwestern corner of ithe building. Within a copper box in the stone were placed significant documents connected with the founding of the National Academy and of the Research Council and lists of the members of both organizations. It is expected that the building will be ready for occupancy in the fall of 1923. SCIENTIFIC NOTES AND NEWS Tr National Academy of Sciences will hold its autumn meeting in New York on Tuesday, Wednesday and Thursday, November 14-16, 1922.

DISCUSSION AND CORRESPOND- ENCE STELLAR DIAMETERS THs determination of star been a matter of considerable interest since the first measures of Betlegeuse were published from the Mount Wilson Observatory. Various predictions have been made for the apparent diameter of stars by Eddington, Wilsing and Hertzsprung, based directly or indirectly upon visual estimates of brightness, eolor and spectral type. The recent work of Coblentz at the Lowell Observatory has afford- ed means of determining new curves of spectral intensities giving data for a revised correla- tion of temperatures and spectral types. Such information, together with the direct thermo- electric measures of stellar radiation made by Coblentz both at the Lick and the Lowell Observatories, affords the basis for the calcula- tion of a star’s surface area if its distance is known, or, wanting aceurate parallax deter- minations, the apparent angular diameter can be computed on the grounds of black body radiation. This serves at least as an inde- pendent method of checking star diameters, and the results of its application to the three stars whose diameters have thus far been measured by the interferometer method may be of gen- eral interest, and are given below: diameters has Russell, SCIENCE 5385 DIAM.

Since, however, this assump- tion is fundamental in applying the laws of radiation from which ithe diameter is com- puted, it is rather remarkable to find stars radiate as nearly like black bodies as the bit of evidence herein contained would seem to show. H. T. Stetson HARVARD UNIVERSITY, ASTRONOMICAL LABORATORY TINGITIDAZ OR ‘TINGIDFE AGAIN “To be or not to be’—Tingitide or Tingide? Logomachy is a “war about words.” It seems .that I have involved myself in such a ‘merry war, driven thereto by my desire as a scientific editor to get at the bottom facts as to what is the correct scientific family-name to give to those insignificant, but very interesting and beautiful little creatures, commonly known as “lace-bugs.” In a little article published in Science (N. S.), LVI, 1922, pp. 334-335, I found in favor of the family name Tingitide. Now comes that excellent entomologist, Pro- fessor H. M. Parshley, of Smith College, and reminds us that in an article published in Psyche, XXIII, 1916, p. 129, he had found in favor of Tingide. His argument in brief is founded upon the statements: 1. “We ean not be sure that Fabricius did in fact adopt the Greek word Tiyyts, the name of a city.” 2. “His use of the genitive Tingis [in a foot- note] shows us that he considered the word his own and indicates what its Latin declension should be.” . I regret that I had completely overlooked Professor Parshley’s article, and duly apolo- gize for the oversight. I am, however, con- 536 strained to state in brief that what he says does not carry conviction to my mind. - As to his first postulate I may indeed say that “we can not be sure” of anything. Fabricius has been dead for over a century, and not even through Sir Oliver Lodge or Conan Doyle can we get into touch with him and ascertain definitely what he was thinking about when he first coined the generic name we still use. But we do know that he had the habit of coining generic names from those of ancient towns and cities. The word Tingis had been in existence two thousand years before Fabricius was born and in its Greek form Tiyyts and in its Latin forms Tingi or Tinge could be found in any dictionary Fabricius might have consulted. The word was no more “his own” than hundreds of other words he used in his writings. It is difficult for me to believe that Fabricius out of the depths of his subconscicus mind fished up an altogether arbi- trary combination of letters, T-i-n-g-i-s, making out of them, as Professor Parshley says, “his own word.” The nomenclatorists of the time of Fabricius had not yet reached the stage attained at a later date by some of their succes- sors, who took random combinations of letters and then by various transpositions and com- binations manufactured words without mean- ing, which they employed for generie and spe- cific terms. Fabricius was a disciple of the old Linnean school and used the Latin language. I question whether he had a sense of “proprie- torship” in words. The fact that he employs Tingis as the geni- tive only shows that he thought that this was the genitive, after the analogy of some other words in the Latin language, and that he did not take the trouble to ascertain what was the true declension of the noun he was employing. Humanum est errare. The genitive of the Latin noun Tingi or Tinge (the equivalent of the Greek Ttyytc, must have been Tingitis, as shown by the adjectival form tingitanus, used by Pomponius Mela, Claudius Mamertinus, et al. Fabricius simply made a slip in his de- clension, which it was easy enough to do. With all due respect to the conclusions of Professor Parshley I contend that we are deal- ing with an old Latin word (found also in the SCIENCE [Vou. LVI, No. 1454. Greek, where it has an i-stem) and that Tingitide is the correct form of the family name, sanctioned by the use of such eminently capable scholars as Stal (by the way, an ex- cellent linguist), Champion, Oshanin, Horvath, Osborn, Drake and a multitude of others. W. J. Houtanp Carnrciz MUSEUM, A MINIATURE PHOTOGRAPHIC DARKROOM Necessity has mothered many an inspira- tion. This trite exclamation was brought to mind by the sudden need of providing dark- room facilities when our commodious attie quarters were closed in order to lessen fire risk. Two alternatives suggested themselves, either to partition off a eorner of a room or ‘to con- struct a portable light-proof developing box. Past experience with small stuffy darkrooms was recalled, and the writer accordingly under- took to build a dark box as a venture. The con- venience of this box, its adaptability to many photographic purposes, and the successful results following its use have led to the pub- lication of this announcement in the hope that others, at present deterred from attempting ‘photography through lack of facilities, may find that the way is easily open. This miniature darkroom is constructed of pressed wood-pulp board nailed over a light wooden frame. Dimensions of 36 inches for width 24 inches for depth and 20 inches for height have proved to be entirely satisfactory. At the lower part of the front face an opening of about 24 by 10 inches admits the arms and hands of the operator. This opening is ren- dered light-proof by two thicknesses of close- woven black sateen cloth continuous with two sleeves. By having the cloth considerably larger than the opening and shirring the edges, free movement of the arms is afforded by the bulging central portion. The ends of the sleeves are made close fitting by elastic bands. Black sateen bloomers can be bought ready made and are of the exact pattern and size, with shirring and elastic fittings ready for attachment to the box. Because of looseness of weave, two superposed layers of cloth should be used. The top of the box has a removable light- NovEMBER 10, 1922 tight cover. This is made possible by tacking a tongue of half-inch stripping around the edge of the cover to fit into a trough at the top of the walls. The tongue and trough are painted matt black, a little Jampblack in weak alco- holic shellac answering for this purpose. The interior of the box need, not be painted, although a white coat affords a better view of manipulations in the interior. To view what is going on inside the box two small windows are provided at the level of the eye when the box is set on a table. The window in front is of clear ruby photo-safe glass, the one opposite is either of ruby glass or trans- lucent ruby fabric. Behind the rear window is placed an electric bulb operated by a switch inside. Another inside switch controls a socket on one wall which may interchangeably have a low eandle-power light for lantern slide making or a high power light for exposing develop- ment papers.

LA Mer. Calculation and experiment show that complex formation (quin- hydrone) in the case of nine substituted quinone- NoveMBErR 17, 1922] hydroquinone systems, is not sufficient to cause any perceptible drift in the values of [[o at least in acid solution when the latter is determined over a wide range of concentrations by the method of Clark, the concentration of the quinone sub- stances yarying between .001 to .003 M. Impuri- ties whose potentials approximate that of the system under examination so closely as to evade detection by differential titration cause pro- nounced drifts, the extent of which depends upon the amount of impurity present as well as whether the impurity has the higher or lower potential. Hlectrometric titrations of silicic acid: WILLIAM STERICKER. Silicic acid was titrated with sodium hydroxide in order to determine what salts it formed. The sol was prepared from ‘reerystallized sodium metasilicate and was carefully purified by dialysis. The pure sol gelled readily. There was no indication of the presence of hydrogen ions or of the formation of any salts. The titration of a sodium silicate solution indicated that this may have been due to polymerization of the acid. Although the first results would indicate that sodium silicate is completely hydrolyzed in dilute solution, titrations with phenolphthalein indicator show this is not so. Synthesis of urea with the enzyme urease: Ep- WARD Mack and DonaLp 8. Vi~tars. The rever- sible action of enzymes has been already shown in several cases, but has never been demonstrated for urease. In the present paper, it is proved beyond any doubt that the equilibrium in the re- action (NH»).CO + 2H20 =>» (NHy4)oCOg can be approached from the (NH4)9COg side, and that the presence of urease hastens very decidedly the attainment of equilibrium. Previous failure to detect the effect was due to (1) starting with too dilute a solution of (NH4).CO3 and (2) not waiting a long enough time for the action, which even in the presence of urease is slow. The action of urease in the decomposition of urea: Epwarp. Mack and Donaup 8. VILLARS. ‘From the work of E. A. Werner and others it seems probable that urea in its reaction with water to form ammonium carbonate takes two courses: (1) it forms ammonium cynanate as an intermediate product, which is itself changed to ammonium carbonate; and (2) it forms ammo- nium carbamate, which is hydrolyzed to car- bonate. By a process of elimination, it has been possible, in the present paper, to show that it is the transformation of urea into ammonium car- bamate which is catalyzed by the presence of the SCIENCE 579 enzyme. Process (1) is not affected by urease. It proceeds at its normal rate in the presence of the enzyme. ’ The acceleration of the hydrolysis of mustard gas by alkaline colloidal solutions: Roprrr E. Witson and Evrerrrr W. Fouuure. A careful series of experiments was carried out to deter- mine the mechanism by which alkaline colloidal solutions, such as those of sulfonated corn oil, so greatly accelerate the removal of mustard gas from contaminated clothing. It was found that these accelerating solutions do not increase the solubility of the mustard gas in the aqueous phase nor the specific rate of hydrolysis, but that in solutions of proper alkalinity they act as car-. riers of mustard gas. The acid produced by the hydrolysis precipitates out tiny oil globules in the aqueous film adjacent to the liquid mustard. gas, and these globules rapidly dissolve unhydro- lyzed mustard gas, and are then swept up into the alkaline portion of the solution and redis- solved, thus permitting rapid hydrolysis of the mustard gas which they carry. Part of the ac- celeration is also due to the fact that these col- loidal solutions keep the mustard gas spread out jn a thin film on the cloth, instead of causing it to draw up into globules, as happens in the pres- ence of solutions of higher interfacial tension. Hydrogen ion concentration and photochemical reaction velocity: G. S. Forsrs and J. C. Woop- HouSE. The speed of photochemical oxidation of quinine by OrO3 in unvaried concentrations is nearly constant from 0.5NH SO, at least to 2.5NH»SO,4. Below 0.5N, the order of reaction with respect to hydrogen ion N,, increases. At 0.01N (the lowest concentration practicable) it is about 1 and is rapidly increasing, presumably toward 2° the value of N,, in the dark. Previously N .,, had been shown, as small con- 3 centrations were reached, to increase from 0 to 1, its value in the dark. The conclusion follows that the oxidation is a reaction stage separate from a preceding stage of photochemical sensi- tization, and slow with respect to it only at low concentrations. Such relations are doubtless more common than suspected. The inhibition of the photochemical decompost- tion of hydrogen peroxide solutions: Wm. T. ANDERSON, JR., and HueH 8. Taytor. (1) The inhibitory effects of 25 typical organic com- pounds on the photochemical decomposition of hydrogen peroxide solutions have been studied im four definite spectral regions of the ultra-violet; (2) The inhibition by such agents has been asso- 580 ciated with the absorptive capacity of the organic compounds for ultra-violet light. A striking eor- relation between these factors has been obtained in the case of benzene, several esters, acids, amides, ketones and alkaloids. The retarding ae- tion of amines and alcohols requires an explana- tion based on other causes than adsorption of light; (3) It has been shown that the inhibitors act more efficiently when in the peroxide solutions than when in a sereening solution of’ similar thickness and concentration. The reduction of copper oxide by carbon mon- oxide and the interaction of carbon monomide and oxygen in the presence of copper and of copper oxide: H. A, Jones and Hueu S. Taytor. (1) The reduction of copper oxide by carbon monoxide has been shown to be an autocatalytic process, copper being the autocatalyst; the reduc- tion occurs at a copper-copperoxide interface; (2) The retarding action of carbon dioxide and of oxygen on the primary reaction of the reduction process, i. ¢., the formation of the copper nuclei, has been pointed out; (3) The mechanism of the carbon monoxide-oxygen catalysis over copper oxide has been shown to be alternate reduction and oxidation of the copper oxide; (4) The mechanism of the catalysis in the presence of copper has been shown to be oxidation of an ad- sorbed layer of carbon monoxide; (5) It has been established that oxygen is a poison in the combination of carbon monoxide and oxygen over copper. \ The calculation of critical values for binary mixtures: A. G. Loomis.’ One of the greatest ex- perimental difficulties in the study of the pressure- temperature composition surface for binary mix- tures in the accurate determination of the critical values for the various mixtures. It is shown in this paper that by employing the equation of Dieterici, which is quite accurate in the critical region, the entire critical line may be very closely calculated; this equation leads to better results than the equation of van der Waals. The com- position of the mixture with minimum critical temperature can be very accurately caleulated by ax finding the expression which makes — a minimum, where az and ba are the attraction and volume constants, each expressed as a quadratic function of the composition. By employing the conditions for phase equilibrium on the critical line and introducing the equation of state in the expression for the free energy of the system, the composition of the mixture with maximum vapor pressure is accurately calculated when the values 7y and Vo SCIENCE [Vou. LVI, No. 1455 of each phase are equated and put equal to 2b, as demanded by the equation of Dieterici. Compound formation and ionization in fused salt mixtures: JAMES KENDALL, E. D. OrirrEen. DEN and H. K. Miuimr. A study of the freezing. point curves for a large number of systems of the types aluminum chloride—metal chloride, aluminum bromide—metal bromide, antimony tri- chloride—metal chloride has shown that here, as in other fields, the extent of compound forma- tion between the two components is primarily dependent upon the diversity of their constituent radicals. The effect of subsidiary factors, such as valence, unsaturation, internal pressure and atomic volume, has also been investigated. Ionization is found to run parallel with com- pound formation in the few systems for which data are now available. The work is being con- tinued. A low temperature electrolyte: W. H. Ropz- BUSH and THEODORE: 0. YNTEMA. Hydrogen chlorid and nitric oxid form a compound at low temperatures of an intense purple color. This is of interest because G. N. Lewis has pointed out that nitric oxid is the only molecule. containing an odd number of electrons that is not colored. It was predicted that this compound would show conductivity in the liquid state. This prediction was verified, a conductivity of 10-3 being easily obtained at 130° K. This is believed to be the lowest temperature at which electrolytic conduc- tion will be obtained. Speculations are offered as to the nature of the compound. Transference numbers of sodium and potassium in miged chloride solution: R. F. SCHNEIDER and S. A. Bratey. The transference numbers of sodium and potassium have been determined in solutions with a total concentration varying from 0.1 to 1.6 N and with varying salts ratios of from 3 KCl and 1 NaCl to 1 Kel and 3 NaCl. While the conductance of such solutions conform to calculated values on the basis of the isohydric principle the ratios of the transference are widely different from the calculated. At a total concen- — tration of 0.2 N and a salt ratio of 3 Kel to 1 NaCl the transference number of the sodium becomes practically zero, indicating that the sodium is not only transported as the cation but is also tied up in a complex anion to such an extent that it moves in both directions at the same rate. The data show that the theory of complete dissociation as advocated by Ghosh can not possibly hold. CHARLES L. Parsons, Secretary Nzw SERIES ANNUAL SUBSCRIPTION, $6.00 Vou.

Why should anybody endow a chair of biology? When I began the study of the subject a little more than a quarter of a cen- tury ago such things were not done. In most of our large universities biology had a fairly secure position, but in all but a very few of the small colleges, at one of which I am proud to say I had the privilege to study, if present at all it was so distinctly only on sufferance. Much doubt existed and was often expressed as to whether this novel subject had any disci- plinary value in the training of the youthful mind, or had any particular cultural worth in the producing of better citizens. Those of us who were irresistibly lured, by the fascination of the wonderful field opened to our vision, to spend most of our time in the biological lab- oratory, were looked upon by our fellow colle- gians as queer freaks of nature, and would certainly have been called Bolsheviks had that overworked appellation been current verbal coin in those days. For the subject distinetly lacked respectability. It was thought by those who pursued the eclassies or other orthodox lines of educational conduct to be a messy business, was known to be smelly, and was generally held to be low. This attitude inevitably called forth a defense reaction on the part of its callow devotees, which resulted in distinctly worse messes and smells than were really requisite for the suecessful pursuit of knowledge in the field. Now all this has changed. Biology has come 1 Papers from the Department of Biometry and Vital Statisties, School of Hygiene and Public Health, Johns Hopkins University. No. 80.

Lichty Chair of Biology in that college. 582 into its own, and the security of its position in the educational world can not be shaken even by so doughty a champion of the powers of intellectual darkness as Mr. Bryan. What has happened in these twenty-five years in biology? And what of the present and of the future? Can we find in the efforts and achievements in this field due warrant for that intellectual respectability that biology has now gained, and for that clear faith in the future which is im- plied in Dr. John A. Lichty’s splendid endow- ment which we are here gathered to dedicate? Perhaps as good a method as any of getting light on this matter will be to attempt a review of the major trends of biology in the past and the present. In doing this we shall find that in every case these trends of ‘thought and research have been responses to some quite naive and simple bit of intellectual curiosity, of the sort likely to arise in a child’s mind, if he turned his thought at all to living nature about him. It may fairly be said that up to the time of Darwin and Wallace and the “Origin of the Species,” all biology busied itself with the answering of one phase or an- other of the following two naive questions: First, how many and what different kinds of animals and plants exist, or have existed, on the face of the earth. Second, regarding living animals and plants as ingenious and complex contrivances, but after all not fundamentally unlike other con- trivances, how are they put together and how do they work? Every boy and girl who collects butterflies, or who pulls a wasp to pieces in order to locate and with safety observe the behavior of i's “stinger,” is in a rough and ready way repeat- ing in his own development the history of the growth of our present knowledge of biology. He is trying on the one hand to get together a collection of the different kinds of living things about him, and on the other hand to inform himself as to their structures and functions. Since the publication of the “Origin of Species” a third question, essentially just as naive, ‘but less easy to deal with objectively and practically, has occupied a great part of ‘he attention and effort of biologists. But that it indieates a sort of intellectual curiosity not SCIENCE [Vou. LVI, No. 1456; essentially one bit more sophisticated than the other two, is plain enough if we remember that all peoples to the remotest historical time, and’ including even savages, have not only thought about it, but also have had theories about it. This question we may put in this way: Third, whence, why, and how came the ani- mals and plants which inhabit the earth to be- here at all? It is, as I have said, in an attempt to answer these three questions, in some one or other of their aspects, that all we know to-day about biology has developed and grown. It is an im- pressive fact, recently discussed with great brillianey by James Harvey Robinson? that always in science, biology no less ‘than all the rest, the motivating problems which have led to the advancement of knowledge have been. simple naive questions about quite common- place things. He says: Those to whom a commonplace appears to be: most extraordinary are very rare, but they are very precious, since they and they alone have- made our minds. It is they who have through hundreds of thousands of years gradually en- riched human thought and widened the gap that separates man from his animal congeners. With- out them the mind as we know it would never~ have come into existence. They are the creators. of human intelligence. The mass of mankind must perforce wait for some specially wide-eyed: individual to point out to them what they have- hitherto accepted as a matter of routine or failed altogether to notice. These mind-makers are the questioners and seers. We classify them roughly as poets, religious leaders, moralists, story- tellers, philosophers, theologians, artists, scien- tists, inventors. They all are discoverers and pointers-out. What eludes the attention of others catches theirs. They form the noble band of wonderers. Commonly unnoticed things excite a strange and compelling curiosity in them, and each new question sets them on a new quest. They see where others are blind, they hear where others are deaf. They point out profundities, complexities, involutions, analogies, differences. and dependencies where everything had seemed as plain as a pike staff. Robinson, in what I have quoted, lays em- 2Robinson, J. H.: ‘‘The Humanizing ef Knowledge,’’ Scrmnce, N. 8., Vol. 56, pp. 89-100,., 1922. NovemBer 24, 1922] phasis on the kind of man who sees the prob- lem. Perhaps it may help by ever so little in the production of such men in this laboratory which we are starting on an enlarged career of usefulness to-day, to emphasize the importance for suecess in biology of bemg simple-minded. II Our first question about the different kinds of living things which people this earth led to the important branch of biology which is called taxonomy or classification. This was for a long time the dominant trend of the subject. The first step toward a proper knowledge of the phenomenal world is obviously to get the phenomena classified in an orderly scheme. In piology this takes the practical form of getting different kinds of plants and animals described, named and classified. Linneus was able to classify all the plants and animals known up to 1735. Nowadays no one person would think of attempting so colossal a task, and if he did would fail by virtue of the inadequacy of the human life span. Instead we find thé worker in the branch of biology to-day devoting his life to one, or at most a few, groups of animals. From its onee dominant position taxonomy has apparently fallen to-day, one must reluc- tantly confess, into rather lower repute in the mind of the general biological public. Neither our professors nor our students of biology ap- pear, with a few brilliant exceptions, to be interested in it. One forms the impression that perhaps four fifths of the Ph.D.’s turned out in zoology at ‘the present time not only never have, but probably never will, for them- selves, identify an animal strange to them, and as for deciding whether the unknown creature has been previously described, or placing it in proper taxonomic relation to its nearest rela- tives, such a problem would be as far beyond their powers as it is beyond their desires. By a curious paradox many modern biologists take precisely that attitude towards and about the living world around them in the practical con- duct of their every day working life, which they would logically be expected to take if it were their deepest conviction ‘that each living thing were the product of an act of special creation— SCIENCE 583: God-given and therefore not to be worried about—and that such a process as evolution had never oceurred. Yet it is beyond question that if a young man embarking on a biological career has a desire to make an enduring contribution to knowledge, of permanent value, and incapable of ‘being upset by any future developments of the subject, his best chance of doing this lauda- ble thing is by becoming a careful, accurate taxonomist. If he describes accurately, care- fully and completely a hitherto undescribed. species of animal or plant, in such a way that any one who reads carefully the description can recognize and identify the thing described, he has chiseled for himself an indelible record in the history of man’s intellectual progress. Some there are who will argue that while what has just been said may be true, the niche in the tablets of history carved in this way is too slight to be of any significance, that, in short, systematic or taxonomic work has only a small and unimportant intellectual content, as compared with other sorts of biological study. Such a view of the case seems to me to be singularly lacking in vision. It means that. the commonplace elements in taxonomic, work have been allowed to overwhelm in their view its broad and deep significance. The labors of the taxonomists have alone given us such pic- ture as we have of the inter-relationships, unity in diversity, and diversity in unity, of animate nature as a whole. It is the systematist who has furnished the bricks with which the whole structure of ‘biological knowledge has been reared. Without his labors the fact of organic evolution could scarcely have been perceived, and it is he who to-day really sets the basic problems for the geneticist and the student of experimental evolution. His facts are the raw material from which the laws of organie evo- lution, in the sense that we speak of physical laws, must ‘be worked out. An example of what is apparently a real law of organic evo- Intion, deduced directly from the simplest taxonomic statistics, is found in the fact that the sizes of genera of plants and animals, as measured by the number of species each con- tains, are not distributed in frequency accord- 584 ing to the normal curve of error, as most chance determined phenomena are, but instead obey with extraordinary exactness, as has been shown by Willis and Yule,? the rule that the logarithms of the frequency of genera plotted to the logarithms of the size of the same genera (i. e., the number of species in each), give a straight line. It is with much satisfaction that we find the leading exponent of the reigning mode in present-day biology, Bateson,* saying of tax- onomy : I had expected that genetics would provide at once common ground for the systematist and the laboratory worker. This hope has been disap- pointed. Each still keeps apart. Systematic literature grows precisely as if the genetical dis- coveries had never been made and the geneticists more and more withdraw each into his special ““elaim’’—a most lamentable result. Both are to blame. If we can not persuade the systemat- ists to come to us, at least we can go to them. They too have built up a vast edifice of knowl- edge which they are willing to share with us, and which we greatly need. They too have never lost that longing for the truth about evolution which to men of my date is the salt of biology, and the impulse which made us biologists. It is from them that the raw materials for our researches are to be drawn, which alone can give eatholicity and breadth to our studies. We and the sys- tematists have to devise a common language. The separation between the laboratory men and the systematists already imperils the work. I might almost say the sanity, of both. The sys- tematists will feel the ground fall from beneath their feet, when they learn and realize what genetics has accomplished, and we close students of specially chosen examples may find our eyes dazzled and blinded when we look up from our work-tables to contemplate the brilliant vision of the natural world in its boundless complexity. It seems probable that we shall before long witness a return to a saner attitude than has prevailed in the last quarter of a century in 3 Willis, J. C., and Yule, G. U.: ‘*Some Sta-° tistics of Evolution and Geographical Distribu- tion in Plants and Animals, and Their Signifi- eance,’’ Nature, February 9, 1922, pp. 177-179. 4 Bateson, W.: ‘‘Evolutionary Faith and Mod- ern Doubts,’’ Screncr, N. S., Vol. 55, pp. 55-61, 1922. SCIENCE [Vou. LVI, No. 1456 regard to systematic zoology and botany; and in the training of our students, by not be- ginning specialization too soon and too vio- lently, give them a more adequate conception than they now get of the orderliness and the diversity which together characterize animate nature as a whole. III The dominant mode in biology in my student days was morphology. I was nurtured on the somewhat arid problems of vertebrate cephalo- genesis and the components of the cranial nerves. Probably few students in these days are excited by such problems. A vague aware- ness that there are such things as cranial nerves no doubt suffices and everyone is just as happy. The whole subject of pure mor- phology, as it was cultivated twenty-five years ago, seems singularly sterile now. It was a highly developed discipline, with a set of rules as rigid, and also be it said about as soul- stirring, as those of the Greek grammar. In its fine spun theories about homology, meta- merism and the like, biology got off on a wrong track, which, as is now practically universally admitted, had only a blind ending. But this does not mean, as those of the younger generation are apt rashly to conclude, that the old morphology was of no value. Intrinsically it was of great value. Few things will transcend in importance in the study of biology, the finding out of all that ean be learned about the way in which living machines are put together. As long as this purely descriptive purpose was the primary and essen- tial object of morphological study, all was well. The business only began to go bankrupt when it took on an essentially metaphysical purpose, and a logically bad, not to say hope- less one, at that. For what the pure morpholo- gists of the eighties and early nineties were trying to do was to infer from purely static phenomena (the intimate structure of the body) the dynamic relations in a course of events (organic evolution). Such a _ task would have been perceived to be hopeless long before it was, except for the seductive lure of certain rules by which the game was played, which rules (such as ontogenetic recapitulation NOVEMBER 24, 1922] of phylogeny, certain aspects of homology, ete.) were mistakenly supposed to be natural laws, whereas in point of fact, at the best they were only imperfect expressions of certain inherent necessities of the philosophic principle of organization, and at the worst just plain buncombe. It is unfortunate that in the reaction against this sort of thing which has occurred in the last quarter-century the pendulum has swung so far as to deprive the present day student of biology of a good deal of the exact rigid morphological training that he got im earlier days. There never has been any better train- ing for hand and eye and mind than that which went with the getting of an adequate under- standing of the comparative anatomy of the vertebrates, no matter what field of biology the student subsequently entered upon as a spe- cialty. So generally inadequate is the training in this field, now, I am told, that several of our best medical schools have found it necessary to devote a not inconsiderable part of the time allotted to.anatomy in the medical curriculum, to the study of vertebrate comparative anatomy, because it is essential to the right understand- ing of human anatomy, and the students do not have it when they come, although they have the bachelor’s degree and have been required to take biology. ; We have seen, in the brief sketch which has so far been given of the course of biological events, that two trends of thought and research that were formerly of major importance have on the whole fallen somewhat into a state of desuetude. It will pay us to inquire a little more carefully into the reasons for this change of interest and esteem, because otherwise we are apt to reach the erroneous conclusion that taxonomy and morphology were never of any real importance or significance in the develop- ment of human knowledge, and that our fore- fathers only deluded themselves in thinking that they were. The fundamental reason for the decline in the cultivation of these two disciplines has already been touched upon. It is found in the fact that taxonomy and mor- phology, as originally practised in their pris- tine purity, dealt solely with static aspects of vital phenomena. Now the only thing of really SCIENCE 585 compelling interest and significance about life is its dynamic character. Organisms live and do things. It is only this which makes them more interesting than bricks or paving stones. But by a eurious quirk of the evolution of intellectual matters, the only group of people, before the publication of the “Origin of Spe- cies,” who, as a group if they perceived this somewhat obvious fact, did anything about it, were the physiologists. The historical development of physiology was bound up with and a part of that of medicine, rather than what we now call general biology. The first systematic treatise pro- fessedly dealing with physiology as an integral part of general biology was Claude Bernard’s “Physiologie générale” and appeared only in 1872. The significance of this is that, in the main, and with only a few notable exceptions, those who prior to that time had been interested in, physiology had been almost wholly con- cerned with workings of the mechanisms solely of the human body, and even in this somewhat narrow field, the significance of the findings for the science and art of medicine held the fore- most place in esteem. All this has, of course, changed with the considerable development dur- ing the last quarter of a century, of general physiology under the leadership of such men as Loeb in this country, Bayliss in England, and Verworn in Germany. But at its best physiology concerns itself chiefiy with only certain of the internal dynamie phenomena of living things, and this is only a small part of the sum total of the activities which constitute life. That all biology should primarily be concerned with dynamic matzers was first brought powerfully to the attention of thinking men by Darwin. The significance of Charles Darwin’s work upon the intellectual development of his and subsequent times has been variously described and estimated. If we go down to real fundamentals it seems to me that we must conclude that one of the most im- portant elements, at least, lies in the making it so plain as never again to be misunderstood, that ithe essential problems of biology are ques- tions of dynamic relationships and not of static phenomena. The immediate effect of Darwin’s work, at 586 least so far as zoology was concerned, was a curious one. If led to an enormous develop- ment of research in what is perhaps the most essentially static branch of biology, namely, pure morphology. The process of reasoning was something like this. Since evolution leaves a record of its progress in the structures of ani- mals, by studying these structures intensively it ought to be possible to reconstruct not only the course, but even also the method, of evolu- tion. Von Baer’s so-called law, to the effect that ontogeny repeats phylogeny, was held to be the key that would unlock all the secret places of organic evolution, and the biological world went more or less mad over embryology. But as has already been pointed out, this line of attack proved to be sterile, so far as the problem of evolution is concerned. Ontogeny does not repeat phylogeny with anything like that degree of fidelity which would ‘be required if it were to be the means of unravelling the tangled thread of evolutionary progress. And the observed static end results given by the structures of existing animals are capable of being produced in too many different ways, as we now know, to make possible any precise con- clusions from ithe mere study of their form as to the dynamic course of events which led to their existence. IV When this fact had become evident and sunk deeply into the consciousness of the working biologists, the way was cleared for the begin- ning of the great movement towards modern general biology. It is an odd mischance of fate that Darwin, who is the real founder of modern general biology, should not have seen any of its fruits in the declining years of his life, but in- stead only an abortive development resting on a ridiculously unsound philosophy. When bi- ology, at the very end of the nineteenth cen- tury, got once more on the right track (for much earlier in its history it had been there, and only got diverted by a _ bad philosophy as to how the iproblems of evolution could be solved) a new world was indeed opened to our vision. And the pass- word to it was experimentation. To the work- ing biologist organisms once more became living SCIENCE [Vou. LVI, No. 1456 things, not desiccated or pickled corpses. I cannot recall that in my undergraduate days there ever was a living animal in the labora- tory, with ‘the exception of protozoa. Cer- tainly none was ever studied in any but a thoroughly pickled condition. As one looks back now on those days he is horrified not alone ~ at the tortuosity of the intellectual pathway by which we attempted to come upon a knowledge of life, but also at the awful waste of alcohol! The keynote of the new biology was dynamic and its methods were, in the main, experimen- tal. Hach of the old disciplines took on a new life. Morphology became experimental mor- phology; evolution became experimental evolu- tion; a new shoot, ecology, sprang up from the gnarled old root of the taxonomic tree; and in some sense as the crowning glory of the whole edifice, animal behavior and comparative psy- chology began to flourish and attain a respecta- bility never enjoyed by the labors of the old- fashioned naturalist, who observed what he called the “habits” of animals and plants. Since these movements I have named com- prise nearly the whole of the major trends of biology in the twentieth century it will perhaps be worth our while to examine a little more carefully into the philosophy and significance of each of them. For on and out of them is to grow the biology of the future, with all the great advances in knowledge which it has in store. NY Modern experimental morphology may fairly be said to begin with Roux. His philosophy may be summarized in this way: organisms are machines which in their operations follow the laws of mechanics. Their structures are as they are because of the operation of these laws upon the plastic and adaptable material of which they are composed. It is the task of de- velopmental mechanics to discover the specific physical and chemical laws which determine the form of particular structures of the living body. On the whole the most feasible way to go about accomplishing this result is to ob- serve the results which follow upon the experi- mental modification of the physical and chemi- eal conditions which environ the embryonic de- “NoveMBER 24, 1922] velopment of particular structures. Then in the favorable case we shall be able definitely to connect and correlate particular physico- chemical events with particular biological events in a causal way. We shall replace metaphysical speculation in the field of mor- ‘phology with observed physical causation. The results of the last quarter century have abundantly justified the faith of Roux and his followers in soundness of this philosophy. So close are we to the events themselves, however, that we cannot justly appreciate, I ‘believe, the enormous significance of the advance in our knowledge of the fundamentals of biology which have come as the result of the labors in this field of a host of workers, under the leader- ship of Roux in Germany and of Morgan in this country. The important advances in this field have, in the main, come from these two countries. The great activity in the fields of experi- mental morphology and developmental me- chanics has also been in considerable degree re- sponsible for the growth and healthy condition of another major trend in modern biology, namely cytology. This is pure morphology at its best, resting on the sound philosophical pur- pose of the exact description of the minute anatomy of the cell. In this field America has again been a leader. HE. B. Wilson’s book,‘ ‘The Cell in Development and Inheritance,” may well be said to mark an epoch, at least in Am- erican biology. The achievements of cytology in the last quarter century have been of no mean importance. This field of research, for example, has played the leading role in clearing up the age old problem of the determination of sex. The discovery by McClung of a mechan- ism in the germ cells, the accessory or sex chromosomes, and the subsequent great exten- sion and solid grounding of this knowledge by Wilson and his students, have served to take out of the realm of mysticism and put into the clear light of ascertained fact the answer to one of the great biological riddles. Again, in this same period cytological research has laid the structural foundation of the mechanism of heredity. The student of the history of science will note here an interesting fact. Discoveries SCIENCE 587 of major importance in regard to dynamic bio- logical events have here been made by a purely static, descriptive mode of research. This is unusual. Why it has happened so fortunately is because the American workers in cytology, in the period of which we are speaking, have at every stage worked in the closest touch with the experimentalists, and have directed their descriptive studies to problems which have made themselves compellingly obvious from and in the experimental work which was going on at the same time, and in many cases in the same laboratory. A static method has worked in cor- relation and cooperation with a dynamic experi- mental method. We see beautifully exemplified here one of the main functions of descriptive science in general, in relation to experimental science. The descriptive worker endeavors to lay the structural foundation of the dynamic events with which the experimentalist directly concerns himself. The fruitfulness of this method and ideal of work in ‘morphology, as compared with sad sterility of the point of view which vainly attempts to solve in toto dynamic problems by a purely static mode of research as the older morphology did, is ap- parent in the recent history of biology. VI Jennings has somewhere said that “An ani- mal is something that happens.” While this happy phrase might well be taken as the slogan for all modern biology, it expresses with par- ticular aptness the point of view of that major trend in recent biological history im which its author was the one of the most con- siderable pioneers and leaders, namely the study of animal behavior. The development of this subject into the prominence it has enjoyed in the last quarter of a century does not repre- sent altogether quite so sharp a break with the philosophy of an earlier time as was the case in the development of experimental mor- phology. The field naturalist had always properly esteemed the importance of things which happened, and there exists, in the older literature of popular and amateur natural his- tory, a considerable mine of rather accurate observations about the behavior and habits of 588 animals under natural conditions. Perhaps some day students of animal behavior from the modern view-point will adequately work this body of ore. It will not be an easy, nor a completely profitable task. The trouble of course is that, generally speaking, the naturalist of the old school was not analytical, but rather anecdotal, in his interest in the behavior and habits of animals. It was just this difference that marked off the new school of animal behavior from the old. If what living things do is the most important consideration in distinguishing them from non- living things, it would seem clear that our knowledge of biology in general is bound to be increased if we apply to the study of what they do such precise analytical experimental meth- ods as will give definite knowledge of at least some of the variables concerned in the determi- nation of why they do it. In short, instead of interpreting what animals do in terms of a crude anthropopsychism why not be objective, and by experimentally modifying and control- ling the animal’s behavior learn something of the biological processes back of it? Around 1900 it was pretty unanimously agreed that this was the thing to do, and it was done. For a few years a glib familiarity with “tropisms” and “reflex movements” was as es- sential to biological respectability as a corre- sponding acquaintance with “genes” and “cross- ing-over” is now. Two schools of thought and opinion erystallized, the one led by Loeb and the other by Jennings. They may be charac- terized, with perhaps the least chance of giving offense to anybody, as respectively the more simply mechanistic and the less simply mechan- istic ways of regarding the happenings called life. The two cohorts of followers fought and bled on the battle-fields of “foreed movements,” “trial and error,’ and so on, with the utmost nobility and sacrifice of ink. Quite unfortunately, as it seems to me, this fundamentally important line of research so brilliantly inaugurated, began after a decade or so to languish. Loeb turned off to physical chemistry and Jennings to genetics, and with the generals gone the armies melted away, to ally themselves to what they supposed to be SCIENCE [Vou. LVI, No. 1456 more auspicious, or at least more fashionable movements. The case well illustrates the po- tency of the sheepish elements in human be- havior. For no informed person supposes for a moment that all the problems of animal be- havior and comparative psychology have been completely solved. Quite on the contrary the field has just been well opened up. And it~ is my conviction, based on some personal ex- perience, that there is no other discipline which gives the student such an insight and grasp of fundamentals in the philosophy of biology as does the first-hand study of animal behavior. Every student in training for a career in any field of biology will find it extremely valuable in his future work to have done a piece of care- ful work in animal behavior under competent direction and guidance. VII We come now to the consideration of what, directly and in its numerous ramifications, is the dominant mode in present-day biology. I refer, of course, to experimental evolution. Begin- ning philosophically as a reaction against the sterility of pure morphology as a method of solving the great problems of organic evolution, it owes its actual origin as a major move- ment in biological thought to two cireum- stances, first, the bringing to light of ‘the long- forgotten papers on the mode of inheritance of characters in certain plants by the Austrian monk, Gregor Mendel; and second, to the in- auguration of the biometric method in biology by Francis Galton, Karl Pearson, and W. F. R. Weldon. It was plain enough to the writers of the Neo-Darwinian school, as indeed to everybody else who had grasped anything of the meaning of Darwin’s work, that the basic factors in organic evolution were variation and heredity. Why not, then, study these factors directly, intensively, experimentally, and quan- titatively? There could possibly be but one sensible answer to this question. And because this is so is the reason that genetics and bi- ometry came upon us with such a rush, and have grown and prospered so vigorously. Bateson, in the address to which I have al- ready referred, tells the story of this change NoveMBrER 24, 1922 in viewpoint in the study of evolution very well, and I cannot do better than quote him again: Discussion of evolution came to an end prima- tily because it was obvious that no progress was being made. Morphology having been explored in its minutest corners, we turned elsewhere. Varia- tion and heredity the two components of the evo- lutionary path, were next tried. The geneticist is the successor of the morphologist. We became geneticists in the conviction that there at least must evolutionary wisdom be found. We got on fast. So soon as a critical study of variation was undertaken, evidence came in as to the way in which varieties do actually arise in descent. The unacceptable doctrine of the secular transforma- tion of masses by the accumulation of. impalpable changes became not only unlikely but gratuitous. An examination in the field of the interrelations of pairs of well characterized but closely allied ““species’’ next proved, almost wherever such an inquiry could be instituted, that neither could both have been gradually evolved by natural selee- tion from a common intermediate progenitor, nor either from the other by such a process. Searcely ever where such pairs co-exist in nature, or occupy conterminous areas do we find an intermediate normal population as the theory demands. The ignorance of common facts bearing on this part of the inquiry which prevailed among evolution- ists, was, as one looked back, astonishing and in- explicable. It had been decreed that when vari- eties of a species co-exist in nature, they must be connected by all intergradations, and it was an article of faith of almost equal validity that the intermediate form must be statistically the ma- jority, and the extremes comparatively rare. The plant breeder might declare that he had varieties of Primula or some other plant, lately constituted, uniform in every varietal character breeding strictly true in those respects, or the entomologist might state that a polymorphic species of a beetle or of a moth fell obviously into definite types, but the evolutionary philosopher knew better. To him such statements merely showed that the re- porter was a bad observer, and not improbably a destroyer of inconvenient material. Systematists had sound information but no one consulted them on such matters or cared to hear what they might have to say. The evolutionist of the eighties was perfectly certain that species were a figment of the systematist’s mind, not worthy of enlightened attention. Then came the Mendelian clue. varieties arising. We saw the Segregation maintained their SCLENCE 589 identity. The discontinuity of variation was rec- ognized in abundance. Plenty of the Mendelian combinations would in nature pass the serutiny of even an exacting systematist and be given ‘“specifie rank.’’ In the light of such facts the origin of species was no doubt a similar pheno- menon. Now while it is true that genetics has by no means solved the problem of evolution as yet, and probably by itself never can and never should have hoped to, the intensive pursuit of this line of inquiry during the last decade has enormously advanced our knowledge of general biology. In the first place, thanks to the bril- liant work of Morgan and his students with Drosophila, we have firmly welded the last links in the chain of a definite proof of ithe causal connection between particular visible details of nuclear structure in the germ cells and particu- lar somatie characters transmitted from parent to offspring in inheritance. The “mechanism of heredity” is no longer a thing to speculate and build broad nebulous hypotheses about. We definitely know a good deal about this mechanism and how it works. In the second place genetics, with cytology as a working partner, as we have already noted, has solved at least in broad outline, the prob- lem of the causation of sex. In the third place, the general results of modern genetic study taken as a whole, and particularly the intensive study of the breeding of animals and plants which the getting of these results has entailed, have made it highly probable, as I think most geneticists, at least, will agree, that natural selection as postulated by Darwin, has had but little if anything directly to do with the causa- tion of the evolution of the living things about us. That natural selection is a process always and everywhere going on in nature (except in the case of civilized man, where its operation has been in large degree suspended by virtue of certain attributes of civilization itself) no competent observer of nature can possibly deny. But that it either does or could bring about evolutionary results attributed to it by Darwin seems in the light of our present knowl- edge, indefinitely more improbable than it did twenty-five years ago. To give all the reasons which exist to support this view. would be 590 wholly impossible with my time limitations. But that these reasons have been convincing to a great number of the most distinguished stu- dents of biology in recent years is certain. Because some of them have frankly given ex- pression to their doubts, has led many well- meaning, but wholly uninformed, and somewhat unintelligent, persons to conclude that leading biologists no longer “believe in evolution.” Nothing could be more hopelessly wrong than this conclusion. Every biologist who has got beyond a first elementary course in the subject knows that organic evolution is an observed and observable fact of nature, of something like the same obviousness and certainty as the fact that unsupported pieces of matter fall to the earth. I suppose that no one, even a “Fun- damentalist,” would think of asking a physicist if he “believed in gravitation.” It is equally absurd to ask a biologist if he “believes in evo- lution.” But just as one may appropriately discuss today the relative merits of Newton’s and Hinstein’s views as to certain phases of the problems presented by the phenomenon of gravitation, so may he with propriety debate the significance of Darwin’s theory of natural selection as a causative agent in the pheno- menon of organic evolution. It must seem to a young man or woman em- barking now upon a eareer in biology that the only thing in the subject of any particu- lar importance is genetics. I wish to point out, with a gravity as becoming as it is difficult to maintain while emitting such a platitude, that this is not true. There is a great deal in biology about which we are abysmally ignorant which partakes neither of chromosomes, nor Mendelism, nor yet of “crossing-over.” And, if I mistake not, little light is likely to be shed on these dark places by the just now so bril- liantly flaring torches that I have mentioned. The advancement of biology has at least one point in common with another fascinating sub- ject, the adornment of women. Both progress evolutionally by a series of waves of fashion. Just now genetics is the reigning mode in biology. Nothing could be more charming, but it is neither the only nor the final word in charm. It is apparently hopeless to expect anything SCIENCE [Vou. LVI, No. 1456 like a reasonably balanced development in bio- logical research, and, in consequence, of teach- ing. And perhaps if we had it we should all be bored. But it can do no harm if we think once in a while about some of the fundamental problems of biology which practically no one is even making an attempt to investigate experi- mentally, and towards the solution of which we _ are apparently making little progress. Time will not permit to say all that I should like to on this point, but I feel that I must in some de- gree indicate that what I have just said about the inadequacy of genetics as at present pur- sued, is not merely an idle gibe. To this end I shall diseuss briefly two matters, adaptation and heredity. The really difficult problem of evolution is adaptation. The original student of adaptation as a biological problem was Lamarck. It was the problem that lay behind and beneath all of Darwin’s work, and he was almost the last in- vestigator who in any systematic way busied himself with the problem. It seems to me that there are only two later students of this problem whose work is of very considerable im- portance, Hans Driesch and Lawrence J. Hen- derson. There is an objectively manifest teleology in animate nature. No thoughtful person can fail to be deeply impressed with the ingenuity and beauty with which organisms and their parts are adapted to the attainment of certain ends beneficial to the individual and the race. How came these adaptations about? What is the explanation? In the principle of natural selection Darwin put forward the first and, so far, the only mechanistic explanation of adaptation, though to Hume not Darwin should be given the credit of origination so far as this particular phase of the problem is con- cerned. It took away, if correct, at one stroke any necessity for the operation of supernatural causes in the explanation of the living world. It was this aspeet of Darwin’s theory of natural selection which disturbed thoughtful theo- logians vastly more than the fact of evolution itself, the descent of man from lower animals. For it was and is always possible, even if not plausible, to argue that tthe Creator chose to work in an evolutionary manner in the build- ing of the world. But a strictly mechanistic NovreMBER 24, 1922] explanation of adaptation, if adequate, destroys completely the very keystone of the arch of any theistic philosophy. Nothing could undermine more completely the prestige of a theistic agency than to prove that it is unnecessary— than to show, in short, that the supposed re- sults of its infinite wisdom and omniscience not only would have occurred, but actually did hap- pen as a result purely of natural, mechanical causes without any external, supernatural inter- vention. The question, however, is: did the manifold adaptations which we see in living nature in actual fact arise through the operation of the processes of trial and error and natural selec- tion? A final answer to this question seems to me impossible in the present state of knowl- edge. In the eighties and nineties the answer would have been, among biologists if not among philosophers, almost unanimously affirmative. Today the case seems much more doubtful. Formally it is posstble to explain many par- ticular adaptations by natural selection. Some it appears impossible to explain in this way, even formally. What wants intensive investi- gation is the whole biology, from every con- ceivable angle, of particular adaptations. No more important problem exists. And its diffi- culty should act as a stimulus rather than a deterrent to its study. To solve it, or indeed to contribute significantly to its solution, will require a different point of view and a differ- ent method from that of present-day genetics. It may seem a little ungracious to suggest, in view of the brilliant results of genetic work which I have already mentioned, and which I yield to no one in admiration of, that the present dominant mode of research in genetics can give us only an incomplete and, philo- sophically considered, somewhat superficial knowledge of heredity, but I am unable to convince myself that such is not the fact. My views on this point have not changed since I discussed it in detail some seven years ago. I then said®:— Mendelism finds its limitations, just as did the 6 Pearl, R. Modes of Research New York (Maemillan), 1915. in Genetics. SCIENCE 591 biometric methods in the fact that from the logi- cal standpoint it is essentially a statistical meth- od which studies only the laws of distribution of things given or assumed. It examines only the distribution of hereditary specificities, and not at all, directly, their origin or determination. The former aim cannot be the goal of genetic science. A method which can travel only so far cannot hope to say the last word in the discussion of the problem of heredity. As a mode of research the Mendelian method of analyzing the progeny dis- tributions rather than the ancestral will always be used. It was indeed one of the most brilliant methodological discoveries in the history of sci- ence. But it has limitations in the direction of what it can accomplish per se in elucidating the problem of heredity. It is altogether usual in current discussions of variation and heredity to neglect completely everything which comes between the two end terms of the ontogenetic series, the germ cell on the one hand and the adult soma on the other. But clearly what goes between is a most essential part of heredity itself. It is astonishing how little has been done on these extremely obvious problems. Two of the four general methods which have been employed in the investigations of the prob- lem of heredity have been seen to be essentially statistical, and two essentially biological. The statistical methods—the biometric and the Men- delian—differ fundamentally only in that the former investigates primarily the ancestry and the latter primarily the progeny. Logically ex- actly the same distinction was found between the two purely biological methods—the cytological and the embryological. The former studies the ancestry of the germ cell (gametogenesis), the latter the progeny of the germ cell .(somato- genesis). All ‘of these methods are valuable, and each has contributed to our present knowledge of heredity. No one of the methods alone can, how- ever, solve the problem. They all have at least one fundamental limitation in common. This is that they offer no means of directly getting at any definite information regarding the origin, cause, or real nature of that specificity of living material which is the very foundation of the phenomenon of heredity. The distribution of hereditary specificities, their putative morphologi- eal ‘‘bearers,’’?’ and many other things about them have been studied more or less exhaustively. The things themselves have been speculated about, but not investigated to any but the slightest ex- tent. 592 VUul In bringing to a close this brief and. inade- quate review of the major trends of biology I want to say a few words about a purely practi- cal movement which is rapidly gaining force and seems likely shortly to have a pronounced effect upon the development of the whole sub- ject, including its theoretical aspects, and par- I refer to the rapidly growing recognition of the fact that all of the activities of all living things, including man, are properly a part of biology in a greater or The practical importance of this lies in its corollary that the biologist may and probably does have something important to con- tribute towards the solution of ‘the most various sorts of human problems, agricultural, medical, social, economic, and so on. During the last quarter of a century it has been increasingly forced upon the attention of university teach- ers of biology that students of sociology, of philosophy, of medicine, of economics, and of many other subjects, who had no intention to become professional biologists, not only wanted to, but needed to know something about biology. At first covertly resisted, this need is now frankly being recognized and in some degrees met by the reorganization of courses, and de- partures of varying degree from the traditional method of teaching this subject. This is, I think, entirely hhealthy and desirable. There is going along with this broadening of the view- point of biological teaching a welcome broaden- ing of the opportunities for a useful and profit- able career in biology. There are already many kinds of applied biology attracting young men and women. And quite beyond the range of these somewhat narrow specialties, we are wit- nessing such phenomena as the employment of research workers in general biology by a great corporation manufacturing electrical appli- ances, to mention but a single instance. To one who embarked upon a. biological career twenty-five years ago, solely because he was seduced by the charm of the subject, and who in yielding renounced, against the advice of family and friends, the supposedly certain and considerable rewards which would come if he continued, as he had tentatively started, on ticularly its teaching. less degree. SCIENCE [Vou. LVI, No. 1456 a career in which he might finally become a teacher of Greek, the opportunities for the biologist of the present day seem somehow humorously magnificent. If in what I have said I have succeeded in any degree in indicating the intellectual justifi- cation of Dr. John A. Lichty’s splendid gift to Mount Union College for the endowment of its flourishing department of biology, my principal object will have been achieved. Under the able leadership of Professor M. J. Seott we may confidently expect the work of the department to go forward in close touch with each new and promising field of endeavor which biology presents. I can not allow myself to close with- out expressing, as a biologist, my deep admira- tion and profound respect for the breadth of vision and deep philosophical imsight which is implied in the endowment by a worker of the field of medicine of a chair of general biology. The Milton J. Lichty Chair of Biology is an- other enduring demonstration of the fact that the most enchanting of all the sciences has really come into its own. RayMOND PEARL ScHooL or HYGIENE AND PUBLIC HEALTH, THE JOHNS HopKINS UNIVERSITY EARTH-CURRENT OBSERVATIONS! Tue Department of Terrestrial Magnetism of the Carnegie Institution of Washington is plan- ning to install earth-current lines for system- atic observations: at its magnetie observatories. During this year such lines are being installed at the Watheroo Magnetic Observatory, about 120 miles north of Perth, Western Australia, and some time later similar installations will be made at the Huaneayo Magnetic Observa- tory, about 125 miles east of Lima, Peru; both of these magnetic observatories are conducted under the auspices of the Department of Ter- restrial Magnetism. Various initial investiga- tions concerning best methods of eanth-current 1Presented before the Philosophical Society of Washington, February 25, 1922. The full paper is published in the March-June, 1922, issue of Ter- restrial Magnetism and Atmospheric Electricity, pp. 1-30. NOVEMBER 24, 1922] measurements are at present in progress at the Department’s laboratory in Washington. In order to take advantage of the previous experience gained in earth-current work, and to ascertain the direction in which further study is desirable, the writer undertook a discussion of the available data, especially of the 11-year series, 1910-1920, obtained at the Observatorio del Ebro, Tortosa, Spain. For tthe first time comparisons could be made between the phen- omena of terrestrial magnetism, eanth currents, and atmospheric electricity, as dependent upon extensive observations at the same station. Ac- cordingly, it has been possible not only to con- firm and extend certain results previously reached ‘by others, but also to draw important new conclusions. It is hoped ithat the present investigation, which had to be confined to a discussion of the observational data on magnetically-calm, or on electrically-ealm days, may ‘be supplemented later by a discussion of eanth-current data on disturbed days. lows: (a) The resultant horizontal earth-currents, as observed at the Ebro Observatory, flow, on the average for the year, in the direction from about 29° west of North to 29° east of South, or, approximately, in the direction from the Magnetic North Pole towards south-southeast. The average value, for the magnetically-calm days during 1914-1918, of the potential gra- dient of the component of the current flowing from true North to South was 0.20 volt per kilometer, and that of the component towards _ geographic Hast was 0.11 volt per kilometer, or about one half of the north-south component. The resultant horizontal potential-gradient was 0.23 volt per kilometer, which during electric or magnetic storms may reach a value 0.8 to 1.0 volt per kilometer. (b) The annual variations of the earth-eur- rent potential-gradients and of the components of the Harth’s magnetism, as observed at the Ebro Observatory, may be related to one an- other as cause and effect only to a very minor extent; both sets of variations may have to be SCIENCE The chief conclusions may be stated as fol-. 593 referred, more or less, to common causes. The range of the annual variation of the north-south electric component is about 2.5 times that of the west-east component. (c) The diurnal variation of earth currents as observed at the Ebro Observatory along lines somewhat over one kilometer long is remark- ably similar to that observed at Berlin along telegraph lines, 120 and 262 kilometers in length, from 1884-1887. In both eases the di- urnal variations for the component of the cur- rent along the meridian is considerably more pronounced (2-3 times) than that along the parallel of latitude. The diurnal variation in the north component of the earth’s magnetism is not such as to correspond to the direct mag- netic effect of the diurnal variation of the west- east component of the earth currents. A simi- lar conclusion had to be reached with regard to the east component of the earth’s magnetism and the north-south component of the earth currents. The general conclusion was that the north-south earth-current might be the result of electro-magnetic induction, caused by the fluctuation during the day of the west-east com- ponent of the earth’s magnetism. If it be re- called that all analyses of the diurnal varia- tion field of the earth’s magnetism have shown ‘that the magnetic diurnal variation is in part to be ascribed to electric currents circulating in the regions overhead and in part to cur- rents circulating within the earth’s crust, exact agreements between magnetic variations and earth-current variations are not to be expected. Tt further remains to point out that until we have some knowledge of the actual course or distribution of the earth currents in the earth’s crust and as to how the conductivity of the crust may vary with temperature and other meteorological causes during the day and at the actual place of observation, attempts to find a quantitative relationship between terrestrial- magnetic and earth-electric effects may be fu- tile. (ad) The horizontal vector-diagrams both for the magnetic and earth-electric components vary during the sun-spot cycle in about the same proportion. The earth-current vector- 594 diagram is symmetrical about a line approxi- mately in the direction of the Magnetic North Pole. (e) The extreme diurnal range of the Ebro earth currents reaches its highest values near the equinoctial months, and lowest near the solstitial months. Earth currents, atmospheric electricity, the Aurora Borealis, and the earth’s magnetic disturbances, all show similar annual variations in the ranges of their fluctuations. (f) The potential gradients of earth cur- rents and of atmospheric electricity apparently vary during the sun-spot cycle, the former de- creasing in the direction of normal flow of ecur- rent, and the latter increasing with increased sun-spot activity. The diurnal ranges of the potential gradients of earth currents, as well as of atmospheric electricity, just as is the case for the diurnal variation of terrestrial mag- netism, increase with increased sun-spot activi- ty. (g) There is evidence of a similar six-hour wave in atmospheric electricity, earth currents and terrestrial magnetism. The analyses referred to in (c) are chiefly those ‘by Schuster, Fritsche, Chapman, Walker, and Miss van Vleuten, the method of investiga- tion employed by them being that first suggest- ed by Gauss, which is based on the well-known Amperian rules of deflection of a magnetic needle by an electric current. The general re- sult reached by these investigators, as stated in (c), has been accepted by every modern mag- netician; it post-dates the investigations by Airy and Weinstein quoted by Dr. Sanford in his recent article?. In this connection it may be pointed out that the conclusions drawn by Dr. Sanford do not depend upon simultaneous earth-current and magnetic data at the same station, as was the case in my investigations. As stated above, my present conclusions ap- ply only to possible relations between the di- urnal variation phenomena of earth currents and of the earth’s magnetism. It does not ap- pear that definitive conclusions can be safely reached until we have at the same station un- questioned coincident magnetic and electric 2Earth currents and magnetic ScrENCE, October 27, 1922, p. 466. variations, SCIENCE [Vou. LVI, No. 1456 data, and until we can furthermore consider in our comparisons only that portion of the magnetic diurnal variation caused by systems of forces below the earth’s surface. A fresh examination is also being made re- garding the relations between earth currents and severe disturbances of the earth’s mag- netism, such as occur during the so-called mag- netic storms. There are some indications which may support the views recently advanced by Satyendra Ray?, though I am not prepared just now to make a definite statement. With the view of giving renewed stimulus to systematic earth-current investigations, a special committee, “to consider and report on best methods and instruments,” was formed at the Rome meeting of the International Section of Terrestrial Magnetism and Electricity last May.

Hopkins Medical The work so far accomplished by these col- SCIENCE [ Vou. LVI, No. 1456 laborators includes: an extensive study of American methylen blues, fuchsins, gentian violets, and eosins for bacteriological purposes; a study of eosin, methylene blue, hematoxylin, orange G and safrdnin for various histological purposes; while work is in progress at present on a number of other stains, including methylen green, Bordeaux red, brilliant green, brilliant — cresyl blue, cresylecht violet, pyronin, and acid fuchsin. The results accomplished are so prom- ising that there is reason to believe that the most commonly used stains ean be regarded as standardized before the following winter is over. It will then be possible to work out some method of certification of stains which come up to the standards. None of this work would have been possible but for the cooperation of such a large number of investigators, who have responded to every call for assistance in a most gratifying way. It was not anticipated at the start that such a large number would be found to take part willingly in an investigation of this sort. The work, of course, has been entirely voluntary. The committee would like, whenever reporting on any stain, to give due credit to all of these collaborators but as such a course is imprac- tical the best plan seems to ‘take the present occasion to make their names publie and ex- press appreciation for their assistance. H. J. Conn, Chairman CoMMITTEE ON STANDARDIZATION OF STAINS, NationaL RESEARCH COUNCIL SCIENTIFIC EVENTS THE RAMSAY MEMORIAL THE unveiling of the tablet in Westminster Abbey in memory of Sir William Ramsay, to which reference has been made in SCIENCE, was the last act in connection with the memorial, a history of which is summarized in the London Times. In 1917 an appeal was issued for £100,000 by a committee, under the presidency of Mr. Asquith, and under the chairmanship of the late Lord Reay. At a subsequent date, the Prince of Wales became patron of the fund. The sum collected in cash is £57,645. In addition, the fund has been augmented NoveMBER 24, 1922] by a number of research fellowships instituted by various dominion and foreign governments, of which the capitalized value is estimated at about £60,000, so that the total sum raised in response to the appeal may be regarded as being nearly £120,000. This sum is believed to be the largest ever raised in any country as a memorial to a man of science. The sum collected in cash includes subserip- tions from Great Britain and Ireland, America, Australia, Canada, Chile, China, Denmark, France, Greece, Holland, India, Italy, Japan, New Zealand, Norway, Straits Settlements, Switzerland and Portugal. The following governments have instituted fellowships of the value of £300 a year: Can- ada, Greece, Italy, Norway, Sweden, Denmark, Spain, Holland, while the Japanese government has instituted a fellowship of the value of 4,320 yen (approximately £463). French and Swiss fellowships have been instituted, part of the cash contribution in those countries being used for the purpose. These fellowships are intended to lead to an orientation of many of the most promising young scientists of the world to England. Chemists from Norway, Sweden, Denmark, Holland, Switzerland, Japan and the United States are already at work in England. The Italian and Greek fellowships are at present vacant, and the Spanish felowship has not yet been filled, although it has been provided. Fellows are studying in London, and at Oxford and Cambridge, at the Imperial College of Sci- ence and Technology, Glasgow, and at Liver- pool. A number of British fellows are also at work. The Ramsay Committee has carried out a number of the objects which were set out in the original appeal. A sum of £25,000 has been laid on one side for the purpose of a laboratory of chemical engineering, to be established at University College, London, where Sir William Ramsay held his professorship for twenty-six years. This building has not yet been erected, though arrangements are now in progress. A sum of £14,000 was handed over to a body of trustees, consisting of Sir George Beilby, SCIENCE 597 Sir Hugh Bell, Lord Crowe, Mr. H. A. L. Fisher, Sir Donald MacAlister, Dr. J. C. Irvine and Sir Robert Hadfield, for the pur- pose of founding Ramsay Memorial Feilow- ships in Chemical Science for British students. Each fellowship is of the value of £300. In addition, a sum of £6,000 in respect of Glasgow subscriptions was handed over to the same trus- tees to provide a fellowship of £300 a year for a Glasgow candidate. A medal bas been struck from a design of the French sculptor, M. L. Bottée. A sum of £210 has been paid to University College, Lon- don, for the institution of a Ramsay Medal from M. Bottée’s design, to be awarded annu- ally to the most distinguished student of chem- istry at University College. There remains a small balance of the Ramsay Fund, after providing for the cost of the me- morial tablet, the disposal of which has not yet been definitely settled. THE ZEITSCHRIFT FUR PRAKTISCHE GEOLOGIE Dr. Puinie §. Smivrx, acting director of the U. S. Geological Survey, permits us to print the following letter from Dr. Franz Beyschlag, president of the Geologischen Landesansialt, Berlin: On account of the sad financial. conditions in our country it is probably known to you that the question of the existence of the Zettschrift fir praktische Geologie, published by me and my col- league Krusch, is at stake. Cost of printing and postage have risen so high that we shall be com- pelled to discontinue the Zeitschrift in a short time, unless help comes. From the request of your librarian to the publisher of the Zeitschrift, Wilhelm Knapp in Halle, I gather that there is a lively demand in America for this Zeitschrift. From that I conclude with right that there is an interest in the existence of our publication and that it is not unlikely that some subscribers can be obtained. Therefore I would be especially thankful to you if you would endeavor ~to secure in the interested circles there a considerable num- ber of subscriptions. The publisher could send the numbers regularly through the American Institute in Berlin so that there would be no postage. In this way you would render the 598 Zeitschrift an extraordinary service and it might perhaps be possible to keep it alive. For our common strivings in the field of practical geology it would be calamitous if this Zeitschrift, after so long existence, was now compelled to go under through financial difficulties. It is a good medium for scientific publication so that authors also would suffer through the passing of the publica- tion. For your efforts in the interest of this matter, I pledge my highest thanks. SIGMA XI AT THE UNIVERSITY OF IDAHO THE thirty-eighth chapter of Sigma Xi, to be known as the Idaho Chapter, was imstalled at the University of Idaho on June 5. Fifteen active members, who were elected to the society while connected with other educational insti- tutions, composed the petitioning group. The installation exercises were conducted by Dr. Henry B. Ward and Dr. Edward Ellery, president and secretary of the national society. The charge to the chapter was delivered by Dean Ellery and the symposium was con- ducted by Dr. Ward. Eighteen science men who were formerly associated with the Uni- versity of Idaho Sigma Xi Club were invited to attend the installation ceremonies. Several active members of the Washington State Col- lege faculty were also in attendance. The following officers were elected: Presi- dent, Dr. J. EH. Wodsedalek; vice-president, Dr. M. F. Angell; secretary, Dr. Henry Schmitz; treasurer, Professor C. E. Behre. A formal banquet was held in the evening at Lindley Hall, University Campus. Among one hundred guests of the chapter were Dr. Ward, Dean Ellery, Dr. A. H. Upham, presi- dent of the university; Dr. E. A. Bryan, com- missioner of education of Idaho; Miss Hthel Redfield, state superintendent of public instruc- tion; Dr. Melander, of Washington State Col- lege; members of the Idaho Board of Regents, the associate members of the former Idaho Sigma Xi Club, and the deans and heads of the arts and letters divisions of the university. Dr. J. K. Wodsedalek acted as toastmaster and toasts were responded to by Dr. Ward, Dean lillery, President Upham and Commissioner Bryan. The installation took place during com- SCIENCE [Vou. LVI, No. 1456 mencement week. Dean Ellery delivered the baccalaureate sermon and Dr. Ward gave the commencement address. Dean Ellery’s subject was “The hills of human help,” while that of Dr. Ward was “The struggle of man with wild life in North America.” THE ASSOCIATION OF AMERICAN GEOGRAPHERS THE annual meeting of the association, in connection with the Geological Society of America, will be held at tthe University of Michigan, Ann Arbor, by invitation of the re- gents of the university, on Wednesday, Thurs- day and Friday, December 27, 28 and 29, be- ginning on Wednesday at 1:30 P.M. The president’s address will be given at the opening of the session ‘Thursday afternoon and will be followed by a series of invited papers. Later in the afternoon, by special invitation, the association will visit an exhibit of rare maps belonging to Mr. William §. Clements, a regent of the university. Sessions will be held in the natural science building where exhibition and smoking rooms are available. Members desiring to exhibit papers, maps, ete., should inform Professor C. A. Sauer in advance.

All interested in geography, or any of its allied subjects, are welcomed at the program sessions of the asso- ciation. Hartan H. Barrows, President Ricwarp EK. Dopes, Secretary Storrs, CONNECTICUT, NOVEMBER 7, 1922 NOVEMBER 24, 1922] THE ECOLOGICAL SOCIETY OF AMERICA TuE Heological Society of America will hold its eighth annual meeting at the Massachusetts Institute of Technology on Wednesday, Thurs- day and Friday, December 27, 28 and 29, 1922. In addition to the general sessions, joint meet- ings will be held with the American Society of Zoologists and the Botanical Society of America. Titles and abstracts of papers to be placed on the program should be in the hands of the secretary by December 1, in order to be print- ed for distribution before the meeting. Per- sons not members of the society may present papers on the recommendation of a member. A dinner to which all persons interested in the society and its activities are invited will be held at the Athens Café, 694 Washington Street, on Wednesday evening. The — hotel headquarters will be at the Parker House, Tre- mont Street, where rooms will be available at rates from $2.50 up. Reservations should be made at an early date. A. O. WEESE, JAMES MILLIKIN UNIVERSITY, Secretary © DECATUR, ILLINOIS THE AMERICAN SOCIETY OF NATURALISTS Tue fortieth annual meeting of the American Society of Naturalists will be held in Boston, Massachusetts, on Friday, December 29, in the. buildings of the Massachusetts Institute of Technology. The headquarters of the society will be at the Hotel Somerset, which is also the headquar- ters of the American Association for the Ad- vancement of Science. Rates at the Somerset are as follows: One in a room, with bath, $4 to $6; two in a room, with bath, $5 to 7. Mem- bers are advised to make reservations early. Information concerning other accommodations will doubtless be available for the final an- nouncement of the society in December. The morning session will be devoted to a cele- bration of the birth of Gregor Mendel and of Francis Galton in 1822. For this program the following speakers have been secured: EH. M. East, T. H. Morgan, J. Arthur Harris and George H. Shull. SCIENCE 599 A symposium on Geographical Distribution has been arranged in conjunction with the American Society of Zoologists. For this pro- gram, papers by Glover M. Allen, Thomas Barbour, E. R. Dunn, C. H. Higenmann, P. P. Calvert and C. T. Brues have been secured. It may be possible to announce others later. A memorial to the late Professor Sedgwick, in the form of a lecture by Professor E. B. Wilson, is scheduled for Friday afternoon, closely following the Naturalists’ symposium on geographical distribution. Following instructions given by the Nat- uralists last year, the officers of the society participated, durmg the year, in conferences looking toward federation of the biological soci- eties of America. Notices concerning these con- ferences have several times appeared in Science. The final result of these meetings is a ‘proposed constitution of such a federation which was printed in Science for September 29. It is expected that reprints of this article in Science will be distributed to members of the ‘society along with the final announcement in December. The question of accepting mem- bership in the federation will be presented at one of the business meetings of the society. The annual dinner, with the address of the president, Professor W. M. Wheeler, will be given on Friday evening at the Hotel Somerset. Blank forms for the nomination of candi- dates for membership in the society may be obtained from the secretary. Attention is called to the rule that nominations must be in the hands of the executive committee at least a year before being acted upon. Accordingly, nominations to be voted upon in 1923 must reach the secretary before the close of the meet- ing (eee A. FRANKLIN SHULL, Secretary UNIVERSITY OF MICHIGAN, Ann Arspor, MICHIGAN SCIENTIFIC NOTES AND NEWS Av the dinner of the Natiional Academy of Sciences, held in connection with the New York meeting on November 15, the Draper Gold Medal was presented to Professor Henry Norris . Russell, of Princeton University. Dr. C. G. 600 Abbot, director of the Smithsonian Astro- physical Observatory and secretary of the academy, a former recipient of the medal, made the presentation address and Professor Rus- sell replied. Frienps of Professor Chandler presented in 1910 to Columbia University a fund which con- stitutes the Charles Frederick Chandler Foun- dation. The income is used to provide a lec- ture by an eminent chemist and for a medal to be presented to the lecturer. Previous lec- turers on this foundation have been Dr. L. H. Baekeland, W. F. Hillebrand, W. R. Whitney, F. Gowland Hopkins and Edgar F. Smith. The lecturer this winter will be Dr. Robert H.

Through the efforts last summer of Dr. Charles L. Parsons, secretary of the American Chemical Society, this publication, edited by Dr. Wilder D. Ban- crofit, of Cornell University, hitherto a strictly SCIENCE [Von. LVI, No. 1456 American journal, was brought under the auspices of the two leading British societies and the American group. Mr. Kenneto M. Gouin, formerly associate editor of the American Journal of Public Health, has severed his connection with the American Public Health Association and the American Social Hygiene Association, to be- come editor of the publications for the Rocke- feller Foundation. The Journal will be edited in future by Dr. Henry F. Vaughan, commis- stoner of health of Detroit, Michigan, assisted by an editorial board composed of Dr. M. P. Ravenel, of the University of Missouri, and Mr. A. W. Hedrich, secretary of the associa- tion. Mr. Wituis H. Ric, of California, has been appointed assistant in charge of the division of scientific inquiry of the Bureau of Fisheries.

Mr. Paut Croun, formerly research chemist of the New Jersey Zine Company, has been engaged by the Patton-Pitcairn Division of the Pittsburgh Plate Glass Company. THE Journal of the American Medical Asso- ciation states that Professor Ramén y Cajal was not able to be present at the recent unveil- ing of the portrait statue at the medical school of Zaragoza, but a letter from him was read in his name, saying that he doubted whether he would have had courage to witness the unveil- ing of his statue even if his health had allowed it. He said he feared tthe statue would ask, “What have you done to deserve ithis honor? Are you not ashamed to be so distinguished when no memorial has been erected to .. .” and he named several Spaniards who had won international recognition among the scientists of ‘their day. He added that the car of Spanish NoveMBER 24, 1922] civilization has been running along itoo long on merely the two golden wheels of ant and litera- ture. It needs two more wheels to keep abreast with ‘the vest of the world, a wheel of science and a wheel of industry. Epwin F. Hopkins has resigned as plant pathologist of the University of Missouri to accept a position as plant physiologist with the Marble Laboratory, Inc., of Canton, Pa. He will be engaged in a study of problems related to cold storage. Leave of absence has been granted by the Corporation of Yale University to Dr. Lafay- ette B. Mendel, Sterling professor of physio- logical chemisry, to enable him ito deliver a course of lectures on ithe Hitchcock Foundation at the University of California in the late spring of the present university year. It is the intention of Professor Mendel ito leave New Haven afiter the dedication of the Sterling Chemistry Laboratory in April, to join the faculty of the University of California for the ‘intersession, which continues from May 14 to June 23, 1923. Professor Mendel has chosen for his subject “New aspects of the physiology of nutrition.” Dr. CHarues H. Griupert, of Stanford Uni- versity, California, who during the past sum- mer has made an extensive investigation of the salmon fisheries in the Alaska Peninsula Fish- eries Reservation, created in February, 1922, was in Washington from October 18 to 26 conferring with officers of the Bureau of Fish- eries regarding conditions tthat he had found in the reservation, outlining future work to be taken up there and discussing the regulations necessary for the calendar year 1923. Dr. Gil- bert visited Seattle on November 16 and 17 for the purpose of conferring with people operating in the Alaska Peninsula Reservation and discussing permits that will be issued for the operations that will be allowed in the reser- vation the coming year. A Danis# scientific mission, under the lead- ership of Professor Olufson, accompanied by the French savant, Professor Bourecart, of the Sorbonne, left Paris early in the present month on a six months’ expedition in the northern SCIENCE 601 Sahara, where it will cover a distance of some 3,000 miles. The members of the mission in- clude ‘the botanist, Dr. Gram, and the geolo- gists, Drs. Storgaard and Kayser. The party, which will start from Tunis, intends to make a detailed study of the Shat-el-Jerid. From Nefita it will proceed to Tuggurt, and thence to Wargla, in the Algerian Sahara. Next it will go to Insalah, and endeavor to explore the Hoggar Mountains. Cuas. R.

He was the author of important contributions to mycology. UNIVERSITY AND EDUCATIONAL NOTES THE annual report of ithe treasurer of Yale University for the year ending June 30 records an unusually large number of gifts, made to meet the conditions of the $3,000,000 sub- scribed to general endowment by Mrs. Stephen V. Harkness. As a result of these contribu- tions and the establishment of six new pro- fessorship funds in memory of John W. Ster- ling, ’64, of almost $250,000 each, the total of Yale’s endowment funds is shown to be $32,662,011.95, an increase of $6,985,001.25 in the last year. Gifts for building and other non-permanent funds received in the same period aggregated $1,651,290.68, while gifts to income amounted to $740,642.24. Included in the latter were contributions of $185,000 from the General Education Board and $30,000 from the Commonwealth Fund to enable the Yale School of Medicine to provide funds for the reconstruction of two wards in the New Haven Hospital, and to build laboratories in that institution, with which the school is affiliated; $70,000 more from the Commonwealth Fund towards the expenses of the department of SCIENCE [Vou.

NovEMBER 24, 1922] DISCUSSION AND CORRESPOND- ENCE RELATIVITY To tHe Epitor or Scrence: Like many others, I commonly read whatever, from books to mere notes, by Dr. Edwin E. Slosson, comes to my notice. Generally I am well pleased, but an exception has just occurred. I very much dislike that pleasantly written article on Relativity in the Scientific Monthly for Novem- ber, 1922. I dislike it because, giving the words used the only meanings recognized by layman and scientist alike, save a few special- ists, several of the assertions are sheer non- sense. Certainly no system of equations, how- ever clever, can prove to one of common sense, the existence of a real fourth dimension; that time and space are not wholly independent; that just because we and the Martians may be unable to synchronize our clocks there is no ‘now’; that time is “curved’’; that a phenom- enon may be seen before it happens; that the mere inclusion of gravitation in a more com- prehensive expression eliminates it from na- ture; and so forth, and so on, through a long list of ‘absurdities—absurd, that is, if their customary meanings be given to the words used. Such expressions catch the attention, be- cause they seem to declare the truth of amazing paradoxes, but they are, after all, mighty poor paradoxes, for their whole secret is nothing but the assigning of strange meanings to familiar words; a sort of cryptic writing. Naturally, ~ all such “crazy” expressions, crazy so long as unexplained, inevitably breed contempt for science and the scientist... — Let us, then, in popularizing the thoughts of specialists, first understand clearly just what those thoughts are, and then put them in the words and cireumlocutions of the other fellow. The real relativist is not playing hob with our understanding of nature, however different his descriptions of certain phenomena may seem; but if the language of his average popularizer is to be taken literally, and no hint, as a rule, is given of any other meaning, more topsy- turvy indeed than the Land of Alice is this finite, limitless universe that simultaneously will be, was, and is. W. J. HuMPHREYS SCIENCE 603 TINGITIDA. OR TINGID/E In connection with this subject there are some other points which I think should be men- tioned. The Ionic genitive Tiyyro¢ and the Attic genitive -ewf show without a doubt that the word Tryy: is an «stem. In Latin it would be an i-stem, Tingi, and the genitive Tingis. That there is a Latin word Tinge of which the stem is Tingit does not concern us for Fabricius did not use it. He could easily have done so had he wished. While these words have the same root they have different stems. The In- ternational Rules instruet us to add -ide to the stem of the name of the type genus. They do not expect us to worry about other words based on the same root. Fabricius was a Greek purist and he based his name on the word Ttyy:d, -10G (onic, -ewt (Attic). In writing this word in Latin he did so correctly using Tingis in the genitive. The stem of the name of the type genus is, therefore, Tingi. The family name correctly should be Tingiide. It is unfortunate that Westwood omitted one 1 in writing the family name but before the days of the International Commission this was sometimes done. We often write Mantide for example based on Mantis, genitive -10¢ (Ionic), -ewC (Attic). If we follow the International Rules we must insert the other i and write Tingiide. And most of us agree that the rules should be followed. A. C. BaKeEr BuREAU OF ENTOMOLOGY A CHEMICAL SPELLING MATCH In Science for October 20, Dr. L. O. How- ard comments in rather facetious vein upon a chemical spelling match described in the num- ber for September 29. He mentions his strug- gles with chemical names during the twenty years he was permanent secretary of the A. A. A. §. and rather approvingly drags in a quota- tion from Forel, who seemed to think that no true scientist uses long words. Dr. Howard is more specific and applies this to chemistry. He arouses not the resentment but the sympathy of the chemist because of the suspicion that he is envious of a body of knowledge (call it science 604 for short) that has such a precisely deseriptive and stable system of nomenclature as chemistry. The chemist, if diligent, can make at least one new compound every day or so and in his spare moments give it a name. Often it is easier than deciding what to call a mew baby. The name he gives will generally stick, because only on rare occasions does some other chemist come along and show that the harness got twist- ed when the radicals were hitched up. Then all that is needed is to rearrange the component parts of the name or to substitute “ortho” for “para” or “meta.” The name tells what the substance is. Doubt arises when a short and easy name is applied. For the chemist a good mame is rather to be chosen than great wealth of description, ‘be- cause it is self-contained. The naturalist must have detailed descriptions, preferably with plates, and is happiest when he can make com- parison with “type specimens.” Tn his spare moments the botanist or zoologist digs around in old books and journals with the hope of resurrecting an old name for some familiar plant or animal. This is called stabi- lizing the nomenclature. It is done because such and such a congress decided that the race for supremacy and final adoption shall be won, not by a name that has come swiftly down the years and is known by all, but by one that stayed at scratch, hidden in some dusty volume. Shuffling the cards for a new deal is another delightful diversion. For such names as X_.._.. (Smith) Jones comb. nov. special honors are awarded, particularly to Jones. The pity of it is that somebody else may come along and soon the specimen becomes Y........ Des (Brown) White comb. noviss. In this way the nomenclature becomes fixed. What is queer about a chemical spelling match? To mame a compound for which the formula is given, or to do the reverse, is good training for the memory. Can one imagine a botanical or an entomological spelling match? Could “aster” or “grasshopper” be drawn in recognizable detail by the contestants? The optimistic chemist will concede that the respec- tive drawings could with some confidence be labelled ‘flower’ or “bug,” but could an ex- pert name the species? Yet the pitifully un- SCIENCE [Vou. LVI, No. 1456 scientific chemist who uses long words to cloak his ignorance can at once tell the correct names of two such closely related species as HeSO3 and H2S0.. TAGS WASHINGTON, D. C.

JOHNSON Boston Society or Natura History SCIENTIFIC BOOKS The Minds and Manners of Wild Animals. By Wiuuram T. Hornapay, Se.D., A.M. New York: Charles Seribner’s Sons, 1922. Pp. Xcoaee If every man devoted to his affairs, and to the affairs of his city and state, the same measure of intelligence and honest industry that every warm- blooded wild animal devotes to its affairs, the people of this world would abound in good health, prosperity, peace and happiness. To assume that every wild beast and bird is a sacred creature, peacefully dwelling in an earthly paradise, is a mistake. They have their wisdom and their folly, their joys and their sorrows, their trials and tribulations. As the alleged lord of creation, it is man’s duty to know the wild animals truly as they are, in order to enjoy them to the utmost, to utilize them sensibly and fairly, and to give them a square deal. With these reflections, the dean of scientific directors of American zoological parks pre- sents his volume on the minds and manners of wild animals. And with the following picture —reproduced here only in part—the curtain falls: On one side of the heights above the River of NovEMBER 24, 1922] Life stand the men of this little world—the fully developed, the underdone, and the unbaked, in one struggling, seething mass. On the other side, and on a level but one step lower down, stands the vanguard of the long procession of ‘‘Lower’’ Animals, led by the chimpanzee, the orang and the gorilla. The natural bridge that almost spans the chasm lacks only the keystone of the The great Apes have traveled up the River of Life on the opposite side from Man, but they are only one lap behind him. Let us not deceive our- selves about that. Remember that truth is inex- orable in its demands to be heard. Into this book Dr. Hornaday has put much ef his philosophy of life as well as the choicest of his observations on the behavior of wild animals in nature and in captivity. The moral purpose which impelled the writer to expres- sion is the defense of dumb creatures. Our author takes special pains to humble man by dwelling on his shortcomings. The reader is told that, though endowed richly with mind and gifts of expression and therefore capable of noble achievement in service and self- development, man at his worst is the most bestial of animals and more brutal than the so-called brutes. “The minds and manners of wild animals” will disappoint not a few scientific students of animal behavior because it is not an exact systematic and analytic description of animal experience and action. It will delight almost everyone else by its directness, sincerity and naturalness. For the tens of readers who may get next to nothing from the book because of the ‘experimentalist jbias’—to which the re- viewer must plead somewhat guilty—there will be thousands who gain useful knowledge, insight and a more intelligent appreciation of wild animals. The book should be taken, in the opinion of the reviewer, as a notable conitribution to nat- ural history, not as a scientific treatise on com- parative psychology. It contains a wealth of amusing, interesting, thrilling and enlighten- ing incidents and personal observations, a somewhat biographical assemblage of reflec- tions and conclusions and a unique thought- provoking collection of brief characterizations of animal intelligence and temperament. Such SCIENCE 605 is the contribution to animal behavior and rights which Dr. Hornaday has made from his almost unexampled wealth of experience as zoologist, hunter and scientifie director of zoologieal gardens. The information presented should be of very considerable practical value to all who have to do with wild animals. Ii would be a profitless task to diseuss in Science the scientific grounds of dissatisfac- tion with a book which is primarily an account of personal experiences with wild animals. Conspicuous among them are terminology, def- inition, canons of judgment, inferences and generalizations. Such matters every scientific reader will note, but will he nevertheless be able, as ithe layman almost certainly will, to enter into and profit by the author’s lifetime of intimate contact with wild animals? Let us hope so. More to the point than a recital of the con- tent of this volume is the injunction, “Read it and thus enter into the author’s knowledge, sympathetic appreciation and insights.” Truth is great. The ways of observing it are as varied as human intelleet and temperament. It were a pity to lose the value of the naturalistic in our praiseworthy attempts to. exalt the expe- yimental study of animal behavior and _ ex- perience. Ropert M. YERKES SPECIAL ARTICLES PROOF OF THE POWER OF THE WHEAT LANT TO FIX ATMOSPHERIC - NITROGEN In a series of wheat cultures in solutions, we have recently proved conclusively that wheat plants, even in only six weeks of growth, can fix large quantities of nitrogen from the air. They possess this power whether nitrogen is supplied to the reots or not. Seventeen years ago, Jamieson! made the startling announcement, based on experiments, that all green plants possess the power of fix- ing atmospheric nitrogen. He supplemented this announcement by another ‘to the effect that 1 Report of Agr. Res. Assn., Aberdeen, 1905, et seq. 606 special organs exist on the young leaves of plants whose function it is to fix the air nitro- gen and he called these organs “albumen gen- erators.” This supplement to Jamieson’s first announcement and the somewhat loose state- ment of his proffered evidence on the nitrogen fixation, coupled with the indelible impression of Lawes and Gilbert’s and Boussignault’s ex- periments and conclusions, caused ithe scienti- fic world as a whole to scout or ignore Jamie- son’s evidence and the earlier contentions of Ville and a few others ito the same effect. In 1911, Mameli and Pollacci? published a state- ment of experimental results which were not subject to the criticisms pertinent in Jamie- son’s case and which proved conclusively that a variety of green plants possess the power of fixing atmospheric nitrogen. Later statements by them® only confirmed their earlier asser- tions. They did not accept Jamieson’s supple- mentary statement relative to the mechanism of the fixation in question. liven the world of science is so conservative as not to have caused a general acceptance of the contentions of Jamieson and Mameli and Pollacci, despite the fact that Moore and Web- ster and Moore, Webster and Whitley,® as well as Wann,® have more recently furnished ample confirmatory evidence with fresh water and marine alge as material. In order to fur- nish further evidence for securing an accep- tance of this new view of nitrogen fixation which is directly opposed to the old established view and to obtain data for the wheat plant which has not been studied in that regard, the writers have recently carried out an experiment resulting as indicated in the general conclusion introducing this brief note. Wheat plants were grown in “Shive’s best” solution of an osmotic pressure of 1.3 atmos- pheres. These solutions were so constituted as 2 Atti dell’Instituto Botainco della R.

The containers for the solu- tion were quart Mason fruit jars and the usual technique was employed. Five wheat seed- lings per jar, and six jars of each kind of solution were employed, thus testing thirty plants with each solution. In the case of the’ solution containing no nitrogen, twelve jars were employed, six of them being kept in the greenhouse until seeds were formed. All the other plants were grown for a period of six weeks only. It is impossible now to go into the many interesting features of this and other experiments which we are conducting on the important subject of nitrogen fixation. Suffice it to say that in a number of series of wheat plants grown without nitrogen and with varying quantities of nitrate, definite evidence was adduced that all the wheat plants fix nitro- gen from the air. Even excluding the nitro- gen content of the culture solutions at the end of the experiment, because of some irregular data in the analyses, there is a gain of nitro- gen from the air which varies in different series from 13 to 21 per cent. of the total amount of nitrogen found in the plant. With the nitrogen in the solutions taken into ac- count, these values will be much larger. A series of experiments with barley is now being completed, and promises to yield similar results to those obtained with wheat. Legumes and other plants will now be studied, and many other features of ‘the subject investi- gated. There can be no question now, how- ever, that the teaching of all our books, and nearly all our teachers on the subject to-day are erroncous and must be changed completely to accord with the facts presented by us, and by the other investigators whom we have cited above. As Moore and Webster have put it, authority has too long held sway over logic and experimental fact. It is high time to let those considerations rule. A full, theoretical and historical discussion of this problem will be given in the detailed account of our experi- ments. C. B Lipman J. K, Taytor NovEMBER 24, 1922 THE AMERICAN CHEMICAL SOCIETY DIVISION OF ARGICULTURAL AND FOOD CHEMISTRY C. 8. Brinton, secretary T. J. Bryan, chairman JOINT SYMPOSIUM WITH DIVISION CHEMISTRY Subject: Edible Fats and Oils. Part A—Manu- facturing and Technical David Wesson, chairman OF BIOLOGICAL Manufacture of edible fats and their pounds: L. M. ToLMAN. Refining losses in the manufacture of edible oils: B. H. TuHurman. Each step through the refining process will be discussed relative to vari- ous vegetable oils, cotton, peanut, soya bean and cocoanut. The action of refining materials in removing undesirable products and impurities is the largest source of shrinkage on most oils. Methods for determining the percentage of impurities, such as lecitro-proteins and _ color- ing matter, will be given, both from laboratory and factory determinations. There are emulsions formed and broken, which are described in detail, giving some experiences of handling them in the factory. One that is not yet handled successfully and causes loss should be interesting to the colloidal chemist. Another step in the process illustrates selective absorption by Fuller’s earth and earbon black. Losses due to volatility and solubility are accounted for with averages for different vegetable oils. Corn otl—its preparation and uses: A. F. Srevers. Corn oil is produced as a by-product in the hominy and cornstarch industries. From eighty to one hundred million pounds are pro- duced annually, of which about 70 per cent. is refined for food purposes. Corn oil is classed as a semi-drying oil but has poor drying qualities and therefore does not enter largely into the manufacture of paints. It is used in the mamnu- facture of soap and in making its greatest progress for practically serving the same ipur- poses as cottonseed and peanut oils. Its physical and chemical properties are similar to cottonseed and soya bean oils. The oil prepared from dry process germs is generally lighter in color and contains less free acid than that made from wet process germs. Edible fats in the baking industry: CHARLES A. GuABAU. This paper is based on the data ob- tained in our laboratory which to us is quite inter- esting especially where the homogenizer has en- tered in. The paper bears the following sub- titles: (1) Introductory; (2) defining the various com- SCIENCE 607 kinds of bakery products in which edible fats are used; (3) how the fats are introduced and incor- porated; (4) why fats are added to bakery products; (5) the results obtained by adding graduated quantities of fat to bread doughs (stereopticon plates); (6) tracing the fat through the dough mass with coal tar derivatives (stereopticon plates); (7) introducing a new method of incorporating fat and mixing the dough; (8) the results obtained by homogenizing fats used in the bakery; (9) the distribution of emulsions through the dough mass; (10) deter- mining the carbon dioxide diffused through doughs containing prepared emulsions and doughs in which the fats are incorporated in the general manner; (11) conclusion. The action of shortening in the light of the newer theories of surface phenomena: WASHING- ToN Puarr and R. S. Fuemine. The following definition of shortening and shortness is used: ‘¢Shortening is any fat or fixed oil used as an ingredient in baked products. That material has the greatest shortening power which, when baked in a dough under standard conditions, gives to the product a minimum breaking strength and a minimum crushing strength.’’ A cookie is seen to be essentially a mass of gluten and starch, soaked in a concentrated sugar solution. Short- ening is the only material in dough not soluble in water or wetted by it. Shortening brings about its effects by extending throughout this dough or cake in layers which separate the par- ticles of the dough or cake from one another and prevent the formation of a continuous solid mass. When care is taken to prevent change of the specimen on mounting, the fat may be seen microscopically in the dough and cake, extending in films around the starch grains. An investiga- tion was made to determine the cause of the difference between the shortening power of the common fats. Viscosity, surface tension vs. air and melting point considered alone are seen to be of minor importance. Plasticity is seen to be a more important factor. The work of Langmuir and of Harkins on phenomena at liquid inter- faces is correlated with the differences in shorten- ing power. The close connection between the action of shortenings and of lubricants is empha- sized. Certain physical and chemical requirements of fats in the evaporated milk industry: HARPER F. ZouLER. The evaporation of milk in a vacuum pan at the temperature and pressure under fac- tory operation necessitates the consideration of factors in connection with the constitution and physical make-up of fats which are uncommon in 608 all other industries in which fats are used. The fat should have an iodine absorption number be- low 30. It must contain a minimum of fatty acid esters which, when hydrolized, will yield fatty acids possessing unusual flavors or odors (e. g., arachidie, theobromic, erucic, ricinoleic, ete.). Its ‘‘ethyl ester value’’ should be quite high, preferably, in the purified natural fat, above 12. The content of stearin and pulmitin should not be high enough to raise the melting point above 50° C. It should be a fat which is readily purified and should not therefore contain sub- stance such as phytosterol, sitosterol, alkyl amines, ete. Happily enough, cocoanut oil and palm nut oil which are widely used in the mar- garine industry because of their availability and physical properties come closer to these require- ments than do any of the commercial fats save butter fat. Inasmuch as the margarine industry used cocoanut oil it was but natural that the compound milk industry should choose it. From the standpoint of condensation in the vacuum pan in the presence of the milk, a good grade of cocoanut oil works more admirably than does butter fat itself. The same may be said of palm nut oil. The high iodine number of some butter fats, 28-42, renders it subject to slight rancidifi- cation (hydrolysis) in the vacuum pan and sub- sequent sterilization. Partially hydrogenated cotton oil may be used providing its iodine num- ber is kept about 30, so that its melting point will not interfere with the pan process. The analytical detection of rancidity: Roperr H. Kerr. The analytical tests used for the recog- nition of rancidity, the chemical and physical differences between rancid and sweet fats, and will give some consideration to the mechanism of tancidity and the changes involved in its develop- ment. Rancidity and a method for its detection: H. C. Basuioum and R. J. Nosir. Rancidity of two types, ‘‘A’’ and ‘‘B’’—‘‘A due to volatile fatty acids, ‘‘B’’ due to volatile fatty acids and alde- hydes. Rancidity ‘‘B’’ detected and compara- tively estimated by means of Schiff’s Reagent (pararosaniline acetate dissolved in dilute sul- furous acid solution). A 0.5-1.0 per cent. solu- tion of the oil in kerosene or preferably benzene is shaken with an equal volume of the reagent in a separatory funnel, continuously or inter- mittently for 30 minutes. If the oil be rancid, a violet to blue coloration will appear immediately or within a few minutes in the benzene or kero- sene layer. The color developed is proportional, within limits, to the degree of rancidity. The test is very delicate and especially suitable for SCIENCE [Vou.

The otl, fat and wax laboratory, Bureau of Chemistry, Department of Agriculture, and its relation to the vegetable oil and fat industry: GxrorcE S. JAMIESON and WALTER F. BAUGHMAN. An account of the vegetable oil and fat investi- gations conducted by this laboratory, discussed under three heads: Olive oil and its substitutes, supply of fats and oils during the war and funda- mental investigations. It is almost impossible to get adulterated olive oil past the barriers at our ports. The small amount of adulterated oil on the market is sophisticated in this country by small firms. During the war our imports of fats and oils exceeded our exports. The first complete survey of the fat and oil industry was made. It © was not possible to increase production of cot- tonseed oil, but production and importation of peanut and soya bean oils were greatly increased. Many new possible sources of oil were investi- gated. The chemical composition of some of the vegetable oils have been determined. A repre- sentative number of authentic samples of cotton- seed and peanut oils have been analyzed to establish the limits of variations in the chemical and physical characteristics of these two oils. A new method has been developed for deter- mining the amount of neutral oil in crude oils. Work is in progress on the isolation and identifi- cation of all constituents of cottonseed oil and their effect on refining. Colorimetry as applied to the vegetable oil industry: Daviy Wesson. Cottonseed oil has always been sold on color and various means have been devised from time to time for reading and recording color. Modern conditions have called for more accurate instruments than those used in the past, using Levibond Tintometer glasses. The Eastman Kodak colorimeter furnishes an ideal instrument for measuring and recording the color of samples where colorimetric measurements only are desired. Where it is necessary to analyze a color as in research work, the new Keuffel and Esser color analyzer is to be preferred. A brief note on the examination of the fat from Theobroma grandiflora: W. C. TABOR. A rapid quantitative method for the determina- tion of arachidic-lignoceric acid mixture in peanut oil: ARTHUR W. THoMAS and CHatr-Lau YU. The chemical composition of sunflower seed oil: Grorce 8. JAMIESON and WALTER F, BAUGHMAN. Sunflower seed oil is used in various foreign coun- tries as a food oil and in making butter substi- tutes, soaps, varnishes and enamels. Several million pounds of the seed are produced annually Novemser 24, 1922] in the United States for poultry feed and the production could be greatly increased. The whole seed contains 27 per cent. to 30 per cent. oil and the kernels which constitute about 53 per cent. of the seed contain approximately 53 per cent. oil. It is a drying oil. S. G. 25/25 is 0.9193; refrae- tive index 20°, 1.4736; iodine number (Hanus), 130.8; saponification number, 188.0; unsaponifia- ble matter, 1.2 per cent.; saturated acids, 7.1 per cent.; unsaturated acids, 86.6 per cent.; iodine number of unsaturated acids, 147.9. The oil con- sists of glycerides of the following acids: oleic, 33.4 per cent; linolic, 57.5 per cent.; palmitic, 3.5 per cent.; stearic, 2.9 per cent.; arachidic, 0.6 per cent.; lignoceric, 0.4 per cent. The chemical composition of soya bean oil: Water F, BAUGHMAN and GrorGE S. JAMIESON. The oil was pressed from mammoth yellow vari- ety of soya beans by an expeller. Specific gravity, 25°/25°, .9203; refractive index 20°, 1.4736; iodine number (Hanus), 128.0; saponification value, 189.5; unsaponifiable matter, 0.6 per cent.; saturated acids, 11.5 per cent.; unsaturated acids, 83.5 per cent.; iodine number of. unsaturated acids, 148.7. Bromine addition derivatives of unsaturated acids were made and analyzed. The methyl esters of saturated acids were fractionally distilled under diminished pressure and fractions analyzed. Oil was found to consist of glycerides of following acids: linolenic, 2.3 per cent.; linolic, 51.5 per cent.; oleic, 33.4 per cent.; palmitic, 6.8 per cent.; stearic, 4.4 per cent.; arachidic, 0.7 per cent.; lignoceric, 0.1 per cent. On the use of n-butyl alcohol in the determina- tion of the titer test of fats and oils: H. A. ScHureTtTE and J. H. Draize. A study was made of the effect of substituting n-butyl alcohol for glycerol or ethyl alcohol as a saponifying medium in the official methods for determining the solidi- fying point of the mixed fatty acids, or titer test, of fats and oils. Inasmuch as the melting point, iodine absorption number and titer test of the mixed fatty acids of a series of fats and oils were found to be substantially the same when sodium n-butoxide, glycerol potash or a hydro- alcoholic solution of sodium hydroxide were used as saponifying agents, it is concluded that the former may be substituted for the others without loss of accuracy. A complete and more rapid saponification, without seorching of the resulting soap, is possible. The fat soluble vitamin: H. C. SHERMAN. This paper constitutes a review of present knowledge of the fat-soluble vitamin with special reference to recent advances and practical applications to some food problems. While the fat-soluble SCIENCE 609 vitamin has been studied mainly by means of ex- periments upon rats, it is now known to have very important functions in the nutrition of ani- mals generally, including men. It is needed by adults as well as during growth. A food supply containing only enough of the fat-soluble vitamin for growth will not support full vigor. When the food furnishes too little of the fat-soluble vitamin the body is weakened and becomes more sensitive to infection. On the other hand the body is able to store this vitamin in eases in which the food furnishes more than is required for current needs. The vitamin should be reckoned with as an im- portant factor in food values. The supplementary relationship between foods of high fuel value and those of high vitamin value is discussed. Color vs. vitamin content of fatty foods: Leroy S. PALMER. Commercial TON PLATT. Thoroughness of digestion of different kinds of fats and oils: C. F. Lanewortuy. Studies of the vitamin potency of cod liver oils. II, The effect of season on the vitamin potency of cod lwer oil—spring oil. ArtHur D. Houses. The present paper is one of a series reporting experiments undertaken to determine the vitamin “A? potency of cod liver oils obtained at dif- ferent seasons of the year. To obtain oils of known origin the author personally obtained oils of cod livers from cod fish and rendered the oils under laboratory conditions. Attention is being given to other factors which vary during the year, such as physical condition, sexual activity and diet of fish. Tests with early spring oil from emaciated fish show that .00202 grams of oil daily is fully adequate for the vitamin ‘‘A’?’ growth requirements of albino rats. The influence of light on the synthesis of vitamin A in sprouting white and yellow corn: J. S. Hugues and W. R. Hornacker. A sample of yellow corn having a high vitamin A content and one of white corn having a low vitamin A content were sprouted both in the light and dark. The vitamin A content of the sprouts not in- cluding the grain was tested by the usual feeding test with rats. The sprouts from. both the white and yellow corn grown in the light had a high vitamin A content. The sprouts from neither the white or yellow corn grown in the dark contained much of this vitamin. The results indicate that the vitamin A content of the seed has very little influence on the vitamin A content of the sprout, but that the sunlight is an important factor in the synthesis of vitamin A. Suggestions in technic vitamin work: Epwarp vitamin preparations: WASHING- 610 F. Kouman. We hear much about the destruc- tion of vitamins by the action of heat and oxida- tion. Vitamin A is said to be especially sensitive to oxidation and vitamin C to both heat and oxidation. But with the exception of a very few instances, the experiments from which such con- clusions are derived do not justify an assumption as to whether the destruction noted was really the result of heat or oxidation. No reference has been found in any experiments relating to the effect; of heat and oxidation in which the oxygen content of the product or of the cooking water has been taken into account. Practically all fruits contain more or less atmospheric. oxygen both in solution and mechanically trapped. To eliminate this a high vacuum is not sufficient un- less the container is jarred by rather sharp blows. More important is the oxygen held in solution by the water used for cooking. This can not be re- moved with less than five minutes boiling, nor is a. vacuum effective unless the container is jarred. For temperatures less than boiling, hours are re- quired, and during this time the dissolved oxygen would be more available for oxidation of the vitamin than the oxygen of the air whichis in contact with the surface. Air-free water dis- solves air very readily and therefore must be kept out of contact with air until used. The chick as an experimental animal in vitamin studies. II—With respect to the fat-soluble vitamins: A. D. EmMmertrr and GAIL PHACOCK. Continuing the study of comparing the chick with the rat and pigeon the findings relative to the fat-soluble vitamins indicate in the case of the White Leghorn breed that they are fairly suit- able for test purposes. the pigeon, the fat-soluble vitamin requirements of the chicken are very much greater. The most prominent symptoms are weak legs, partial paral- ysis, enlarged knee joints, dropping wings, weak eyes, accompanied by xerophthalmia which stimu- lates roup, diminished pigmentation of comb, bill, -legs and feet, labored breathing, poor oxidation and loss in weight. In other words, the chick (male or female) needs both the antirachitic and the antiophthalmie fat-soluble vitamins, while the pigeon appears to need relatively little of either. A lack in these requirements is apparently more markedly evidenced in chicks three to four weeks old than in those that are six to nine weeks old. In fact, the onset of the symptoms are so rapid in the younger animals that it is very difficult to bring about a correction of the ailments before death ensues. Jor practical test purposes our SCIENCE In marked contrast with [Vou. LVI, No. 1456 data, which includes some 600 birds, suggest that chicks about seven weeks old are the most suit- able. Compared with the rat, the chick has its limitations as a test animal. It occupies more space, consumes more food, has a greater range of variation in rate of growth, being more diffi- cult to handle and bring through the cary, and critical period of growth. Milk and ice cream as fatty foods: JEROME ALEXANDER. Since milk contains 88 per cent. of. water, the legal 3 per cent. fat means 25 per cent. of the total solids, so that milk is a fatty food. When the casein coagulates it mechanically en- traps the fat, thus forming a greasy curd which is hard to digest. Cows’ milk has a low protective ratio, t. e., the ratio of casein to lactalbumin, and therefore readily forms greasy curds unsuitable for the human stomach. Increasing the protective ratio by adding any colloidal protector (gelatin, eggs, ete.) prevents this difficulty, and is of especial importance in ice cream, where the fat content is much higher than in milk. The effect of colloidal protection in artificial milks and cheese is still to be worked out. A new method for the determination of vanillin: H. C. BasHioum and Frep Y. Herron. This method depends upon the properties of the alde- hyde group rather than those of the phenolic group as is usually the case. In practice, the solution containing vanillin is saturated with hydrogen sulfide in the presence of hydrochloric acid, whereupon a white precipitate of thio- vanillin is produced. The precipitate is filtered off, washed with water and then dissolved in dilute sodium hydroxide solution in which it easily dissolves, producing a yellow color, the intensity of which is proportional, within limits, to the con- centration of thiovanillin. The soda equivalent of sour milk used in baking: Mary P. Witson and H. A. Wess. Baking soda and sour milk ean not be titrated together with any known indicator. A method of preparing alizarine test paper of approximately N/20 strength (one No. 3 quinine capsule of soda in 4% standard ecupful of water), drying and “‘spotting’’ with mixtures of the N/20 soda, measured in drops, and 14 teaspoon of the sour milk under examination, was worked out. When the spot shows no color change, the number of spots made permit caleulation of the equivalent amounts of baking soda or baking powder per cup of milk of any degree of acidity. CuaRLes L.

TANT HAND) DRISS Sees esusli cco a es Oo ee SCIENCE—ADVERTISEMENTS MONOGRAPHS ON EXPERIMENTAL BIOLOGY Just Published The Biology of Death By RAYMOND PEARL, Johns Hopkins University 64 Illustrations. 275 Pages. $2.50 The author has endeavored in this volume to bring to- gether under a unified viewpoint some of the more im- portant contributions which have been made to our knowl- edge of natural death, from three widely scattered sources: namely, general biology, experimental biology, and _ stat- istical and actuarial science. It is impossible in a limited amount of space to cover a field so wide with anything approaching completeness. To do so would require a series of volumes in place of one. This has not been the au- thor’s object; he has instead hoped that the very limitation of this work might stimulate the reader to penetrate for himself further into the literature of this fascinating and important field of biology. Injury, Recovery and Death In Rela- tion to Conductivity and Permeability By W. J. V. OSTERHOUT, Harvard University 96 Illustrations. 259 Pages. $2.50 This volume endeavors to treat certain aspects of biology according to the spirit and methods of the exact sciences. The treatment is confined to certain fundamen- tal problems which have been studied quantitatively. These studies lead to a theory of some aspects of injury, recovery, and death, as well as of antagonism and permeability. The behavior of the organism in these respects may be predicted with a satisfactory degree of accuracy by means of the eqilations which express the theory in mathematical form. After an introduction the author takes up the problem of Methods of Measuring Electrical Conductivity, The Me- chanism of the Process of Death, Injury and Recovery. Antagonism, Anesthesia, Conductivity and Permeability, and concludes with a bibliography. Smell, Taste and Allied Senses in the Vertebrates By G. H. PARKER, Sc.D., Harvard University 37 Illustrations. 192 Pages. $2.50 Sense organs have always excited general interest, for they are the means of approach to the human mind. With- out them our intellectual life would be a blank. Although the ear and the eye have commonly received most atten- tion, the other sense organs, such as those of smell and of taste, are in reality equally worthy of consideration. Smell and taste, together with certain other senses not so well known, form a more or less natural group in which there is a certain amount of functional interrelation and genetic connection, and it is from this standpoint that these senses are considered in this volume. They illustrate in a way principles common to other groups of sense organs, and these principles will be found to be of an essentially dy- namic character as contrasted with the older conceptions in which function has been brought into relation less inti- mately with structure.

Entered as second-class matter January 21, 1922, at the Post Office at Utica, N. Y., Under the Act of March 3, 1879, THE AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE THE BOSTON MEETING Prans for the Fourth Boston Meeting of the association and associated societies are in a very satisfactory state of progress. The local arrangements are being very efficiently cared for by the local committee, whose chairman is Dr. S. C. Prescott, of the Massachusetts Insti- tute. The secretary of the local committee is Mr. Arthur L. Townsend, also of the Massa- chusetts Institute. The preliminary announce- ment for the meeting will be sent, about De- cember 1, to all whose names are on the roll of the association. As has been announced previously, those attending the meeting will have the benefit of special railway, rates, a fare and a half for the round trip, on the certificate plan. This privilege is available for almost all of the United States and Canada. The sessions will (be held mainly in the build- ings of the Massachusetts Institute of Tech- nology, in Cambridge. These buildings have a floor-space of over fifteen acres. Hach society will be able to have its session rooms near the rooms of the other societies, and still under the same roof. Boston is well provided with good hotels and transportation facilities are very convenient. The announcement will contain the usual list of hotels, prices, ete. Those wishing to make arrangements for rooms before receiving the preliminary announcement should address the local representative of their society, care of the secretary of the local committee. It is better to address the hotel directly, which can be done immediately after receiving the an- nouncement. The association hotel headquar- ters will be the Somerset Hotel. Three general sessions are thus far arranged for the fourth Boston meeting. The opening session will be held on'the evening of Tuesday, 612 December 26, in Walker Memorial Hall at the Massachusetts Institute. At this session the retiring president of the association, Professor EK. H. Moore, of the University of Chicago, will deliver an address on “What is a Number System?” The president of the association, Dr. J. Playfair McMurrich, of the University of Toronto, will preside. The second general session will be held on the evening of Wednesday, December 27, in Walker Memorial Hall. This session is to {be under ‘the joint auspices of the Society of Sigma Xi and the A. A. A. S. The address of the evening will be the Sigma Xi address, this year by President Livingston Farrand, of Cor- nell University, on “The Nation and _ its Health.” A general session will be held on Friday afternoon, December 29, in Huntington Hall, Rogers Building, on the old institute site, Boylston Street, Boston. On this occasion the Wilham Thompson Sedgwick Memorial Lec- ture, under the auspices of the Massachusetts Institute, will be given by Professor Edmund B. Wilson, of Columbia University, on “The Physical Basis of Life.” The following list shows the societies, and the names of their secretaries, that have thus far informed the permanent secretary’s office that they are planning to meet with the asso- ciation at Boston: Section A (Mathematics), William H.

Livineston, Permanent Secretary AUTUMN MEETING OF THE EXECUTIVE COMMITTEE THE meeting was called to order on October 21 at 2:10, in the office of Science Press, New York City, with the following members pres- ent: J. McKeen Cattell, H. L. Fairchild, W. J. Humphreys, Burton E. Livingston, Herbert Osborn, Henry B. Ward. Dr. Fairchild was SCIENCE 613 elected chairman for the session. The follow- ing are the main items of business transacted: 1. The minutes of the last meeting of the committee having been already approved by mail, the permanent secretary read the minutes of the proceedings by mail and telegraph, in the interim since the last meeting, which were approved. 2. The permanent secretary’s annual report on the affairs of the association was read and discussed and it was accepted. The principal features of this report are subjoined. 3. The permanent secretary’s financial report was accepted and ordered to be audited. 4. A letter from the general secretary was read, mentioning that preparations are in progress for a program on the “Origin of Ideas,” for the Boston meeting, under the lead- ership of Dr. James Harvey Robinson, and that preparations are well advanced for a joint meeting of Section C (Chemistry) with the Physiological Section of the Botanical Society of America, with a program on “Photosyn- thesis and the Light Relations. of Plants.” 5. The treasurer was authorized to exchange the association’s holdings in U. S. Victory 434 per cent. notes, which are to be retired, for 4% per cent. U. S. Treasury bonds (1947- 1952) of equal face values. i 6. The chairman of the Committee on Con- vocation Week (Dr. J. McKeen Cattell) pre- sented an informal report, which was accepted. This report will appear in Science. 7. Fifty-seven members were elected to fel- lowship in the association, on regular nomina- tions approved by their respective section sec- retaries. The newly elected fellows are dis- tributed among the sections as follows: F, 40; I, 15; L, 1; K, 1. (It is highly desirable that all members who are eligible to fellowship in the association should be elected. Nominations are made by any member on special nomina- tion blanks secured from the permanent secre- tary’s office or from any section secretary.) 8. Certain editorial features of the journal ScIENCE were discussed. It was voted that the present (practice be continued of publishing in full the retiring presidential and vice-presiden- tial addresses given at the annual meeting. 614 9. Several communications from the secre- tary pro tem. of the executive committee for the proposed federation of American biological societies were read and a resolution was adopt- ed stating that the American Association for the Advancement of Science approves the gen- eral aims and purposes of the proposed fed- eration, and wishes to cooperate with the fed- eration in all possible ways. 10. A communication recommending action by the association, on the subject of proposed changes in the copyright laws of the United States, was received from Dr. M. L. Raney, librarian of the Johns Hopkins University. ' The questions thus raised were relerred to a special committee, consisting of: Dr. C. L. Andrews, chairman (librarian of the John Crerar Library, Chicago); Dr. W. W. Bishop (librarian of the University of Michigan); and Dr. John M. Coulter (head of the department of botany, the University of Chicago), and this committee was requested to make recommenda- tions to the council at the Boston meeting. 11. A communication from Dr. Charles B. Lipman (University of California), writing for the Board of Research of the University of California, and one from Dr. C. A. Kofoid (also of the University of California) were read, regarding the great present need for the preparation and publication éf an up-to-date list of serial publications in science, with anno- tations. The executive committee expressed its approval of these communications but was obliged to defer definite action on this subject till some way may be found lby which the asso- ciation may be able to aid this important project. 12. A communication was received from Dr. Henry B. Ward (of the University of Ilh- nois), recommending that the association adopt a general resolution strongly favoring the scrupulous and complete preservation of the national parks of the United States and Canada, against any form of desecration by any commercial interest. Such a resolution was adopted; its text will appear later in SCIENCE. 13. The permanent secretary was authorized to conduct an intensive membership campaign SCIENCE [Vou. LVI, No. 1457 in the states of New England and New York, just preceding the next annual meeting, this campaign to be based on a special request ad- dressed to every member resident in the speci- fied region, asking him to secure two or more new members for the association. 14. It was unanimously voted that the per- manent secretary be instructed to cable and write to Sir Ernest Rutherford, president of the British Association for the Advancement of Science, inviting him to attend the fourth Boston meeting and to deliver an address, prob- ably on Thursday evening, December 28, with the understanding that the association would meet his expenses. 15. The committee adjourned at 6:30, ito meet at Boston, at 10 A.M., December 26. The evening was spent in an informal discussion of the affairs and prospects of the association. Burton EH. Livineston, Permanent Secretary ANNUAL REPORT OF THE PERMANENT SECRETARY Publications.. About 6,200 copies of the “Booklet of Information” have been sent to prospective members. About 6,500 copies of a four-page leaflet have been sent to the med- ical men of New England, inviting them to be- come members of the association. At the end of September a calendar card, emphasizing the association year (October 1 to September 30) was sent to each member with the statement of his dues. About 11,700 copies were sent out. Along with the calendar card went an explana- tory leaflet on membership. . Circularization for new members. During the fiscal year 1922, 23,933 invitations to join the association were sent to members of affili- ated societies. The cards Show that 1,114 new members have thus far been secured in this way. The invitations sent out in the circular- jzation of non-members listed in “American 1A summary of the annual report of the per- manent secretary, on the affairs of the association, for the period from October 1, 1921, to Septem- ber ‘30, 1922.

All members of the Society of Sigma Xi have the privilege of joining the American Associa- tion for the Advancement of Science without paying the usual entrance fee, but it has thus far been found impossible to send a special invitation to each of these, on account of diffi- culty in securing the membership lists of all chapters of the society. All members of the society who are not already members of the ‘association are asked to send their names and addresses and the names of their respective chapters, to the permanent secretary’s Wash- ington office. He will send them literature that will be of interest. At the close of the fiscal year 1922, about 16,200 special invitations to join the association were sent to members of affiliated societies. About 6,500 of these invi- tations went to medical men in New England. Organization. Each section secretary thas received a card list of the members enrolled in his section, with a cabinet for holding the eards. These lists are duplicated in the Wash- ington office, and both sets are kept up to date by additions and alterations. Each section secretary has been asked to secure a mail ballot of his section committee, for at least two nominations for vice-president and chairman of his section, these nominations to be returned to the Washington office, for the use of the council, on a special blank. It will be remembered that the sections nominate, and the council elects, section chairmen and section secretaries. When a section holds a business session, the nominations secured from the sec- tion committee are to be acted on by the see- tion as a whole. More than one nomination is to be presented to the council, in order that the latter body may have opportunity for choice. The council needs also to know how the votes stood in the section committee. A constitution for the proposed federation of American biological societies was adopted at the Woods Hole meeting, August 4, of the pro tem. executive committee for the federation, at which meeting Dr. Herbert Osborn very kindly represented the association. The proposed con- stitution has been submitted to the council of SCIENCE 615 the association, and should be considered at the Boston meeting, when it will be necessary to decide whether the association will become a member of the new federation. The constitu- tion has been published in Scrmnce (Vol. LVI, No. 1448, p. 359, September 29, 1922). The pro tem. committee voted that the aim of the federation would be to make use of the organ- ization of the association, avoiding the duph- cation of organization wherever possible. It is emphasized by the secretary of the pro tem. committee that the main activities of the fed- eration are apt to. concern publications, not the organization of meetings. The pro tem. committee expressed its thanks to the associa- tion for the financial help received in connec- tion with the Woods Hole meeting, and re- quests the association to continue help of this kind during the formative period of the fed- eration. A similar request has been made of the National Research Council. Copies of the proposed constitution for the federation have been sent by the permanent secretary to all members of the section committees of the four biological sections of the American Association for the Advancement of Science, together with letters asking each member to wnite to his sec- tion secretary in regard to the proposed fed- eration and the attitude that should be taken by. the association toward it, a carbon copy of each letter being also sent to the permanent secretary’s office. A number of replies have been received and the permanent secretary hopes, with the aid of the four section secre- taries concerned, to make a report on this matter to the Executive Committee at the first committee session of the Boston meeting. All members of the biological sections are invited to write to the proper section secretary in this connection, sending copies of \their letters to the permanent secretary. To be considered in his report, letters should be in the section secre- tary’s hands before December 1. Divisions, Local Branch and Affiliated Acad- emies.

Paid-up membership for the three years 1920, 1921 and 1922 was 10,002, 10,160 and 10,566. The rate of increase in paid-up membership from 1920 to 1921 was about 50.5 per cent. increase in total membership. From 1921 to 1922 the rate of increase in paid-up member- ship was about four times as great as was the corresponding total membership rate of im- erease. It seems that membership in good standing is a much better index of our growth than as total membership, and this feature is very gratifying. Financial Affairs. The permanent secre- tary’s annual financial report for the fiscal year 1922 will be published in Sctmnce after the annual meeting, at which time a statement regarding the permanent secretary’s budget for 1923 will be made. Burton .E. Livineston, Permanent Secretary REPORT OF THE COMMITTEE ON CON- VOCATION WEEK! THE committee on convocation week ap- pointed by the council of the American Asso- ciation for the Advancement of Science at the Toronto meeting, and consisting of J. McKeen Cattell, Chairman, Herbert S. Jennings, J. Playfair MeMurrich, Eliakim Hastings Moore and Edwin Bidwell Wilson, begs to report as follows : Twenty years ago the first convocation week meeting of our national scientific societies was held in Washington, from December 29, 1902, to January 3, 1903. Prior ito that time the American Association for the Advancement of Science with the societies affiliated with it had 1 This report has been presented to the executive committee and approved. It is printed in ad- vance of the Boston meeting in order that con- sideration may be given to the recommendations that are made prior to their presentation to the council. DECEMBER 1, 1922] held annual meetings in the summer; the American Society of Naturalists, with an affil- ated group of societies in the natural- sciences, had met in the Christmas holidays. Others ‘of the national societies had met at various times and places. The summer meetings of the American Asso- ciation were found unsatisfactory owing to the difficulty of traveling and the wide dispersion of scientific men at that season. There had been a gradual development in the direction of making the American Association an affilation of scientific societies responsible for their own programs, and the special programs of the sections of the association were becoming less _ important. After long discussion, it was con- sequently decided to transfer the meeting to the Christmas holidays, and to make closer the affiliation with the national scientific societies. A committee, of which the late Professor Charles S. Minot was chairman and the chair- man of the present committee was secretary, proposed and arranged a convocation week meeting of the American Association and other national societies to be held during the week in which New Year’s day falls. The plan was to let the meeting follow Christmas day, at a sufficient interval to allow scientific men to spend the first part of the Christmas holidays at home, devoting the second half to the scien- tific meetings. Extensive correspondence was conducted with universities and colleges and about sixty leading institutions agreed either to let their Christmas holidays include the en- tire week in which New Year’s day falls, or in case that, were mot possible to give leave of absence to those who wished to attend the meetings. It was thought that the official recognition of convocation week would lead the authorities of the universities and other institutions to realize that attendance at scientific meetings is a part of the academic duties and privileges of their teachers. Efforts, in part successful, were also made to obtain payment of traveling expenses by the institutions. A further part of the plan of convocation week was to hold a greater convocation of scien- tific, and perhaps also of learned, societies SCIENCE 617 once in four years, in alternation in Washing- ton, New York and Chicago. It was proposed that at the intervening two-year periods the association should meet in a large central city, where there would be accommodation for all the societies to meet with it. In the alternate years—the end of the year of odd numbers in the calendar—the meeting would be held in a smaller or more remote city, and in this case it was assumed that many of the scientifie so- cieties would prefer to meet singly or in groups, often in smaller university towns. This plan has since been carried out, the four-year con- vocation meeting, for example, having been held at the end of 1920 in Chicago, with a very large representation of national scientific so- cieties and scientific men. The meeting last year was held in Toronto, a smaller city, where, however, the arrangements were admirable and the attendance large. The meeting this year will be at Boston, where the facilities are ample for a large meeting. A difficulty has, however, occurred owing to the prescientific arrangement of the calendar, according to which the same day of the week does not coincide with the same day of the month. When New Year’s day came early in the week, many institutions resumed their regular work in the middle of that week, and scientific men found it difficult to be absent to attend meetings of scientific societies at the beginning of their work. The present com- mittee was appointed with special reference to this difficulty, but was authorized to report on other problems connected with convocation week. This year Christmas occurs on Monday and it was not regarded as feasible to postpone the meetings to the following week. The council at Toronto appeared to be nearly equally di- vided among three alternatives—holding the meeting during Christmas week, extending it over Sunday, or postponing it to New Year’s week. It was finally decided to hold the open- ing session on Tuesday. This has ohvious dis- advantages—it shortens convocation week by a day; it requires most members of the soci- eties who wish to be present at the opening to leave home on or before Christmas day; it does 618 not allow a day in advance of the meeting for preparatory meetings of councils and com- mittees. When Christmas occurs on Tuesday, as it does next year, the balance of the week is too short for the meetings of the different societies, for it is desirable that to a certain extent they meet successively rather than simul- taneously im order to avoid conflicts in the programs. Our committee has decided to recommend that when New Year’s day falls on Thursday, Friday or Saturday, convocation week shall begin on Monday of that week and extend through the week; when it falls on Sunday, con- vocation week shall begin on Tuesday of Christ- mas week and shall continue five days; when Christmas day falls on Monday, Tuesday or Wednesday, convocation week shall begin two days later, namely, on Wednesday, Thursday or Friday, the meetings being continued to include, respectively, Tuesday, Wednesday or Thursday of New Year’s week. It is suggested that meetings acceptable to scientific men and to the community might oc- eur on Sunday. Such would be meetings of councils and committees held at headquarter hotels, and perhaps public lectures. Indeed lectures might be given in the churches as is the custom at meetings of the British Associa- tion which always includes Sunday in its week of meeting. It may also be suggested that one of the main objects of scientific meetings is to \bring scientific men together for acquaint- ance and conversation, and that Sunday could be utilized for such personal meetings, as also for smaller excursions, for informal dinners and the like. The situation in which there appears to lbe most occasion for difference of opinion is when Christmas day falls on Monday or Wednesday. It might in these cases be desirable to meet the day after ‘Christmas, so that in the first case the meeting could be completed in Christmas week and in the second case not extend beyond Wednesday of New Year’s week. The com- mittee, however, recommends that the official opening dates be two days after Christmas, though of course any society could place its first meetings on the day after Christmas and SCIENCE [Vou. LVI, No. 1457 the council of the association and other councils and committees must meet on that day. In addition to the convocation-week meet- ings during the Christmas ‘holidays, it seems desirable that the association should resume regular summer meetings. The sections need not be fully organized, and it would not be ex- pected that most of the affiliated societies would meet. The four summer meetings that have been held since the establishment of the winter convocations—in Ithaca, Hanover, San Francisco and this year in Salt Lake City— have been enjoyable ‘to those able to be present and useful to the communities, to science and to the association. The country is large; scientific men are many and have diverse interests. The association should aim to be of service to all in so far as this is possible without sacrifice of other inter- ests. A meeting in summer, smaller and more informal than the winter meetings, more sec- tional in character, enables the association to visit universities and places mot suited to a large winter meeting or impossible when there is only one meeting a year. Hxcursions and social features may be arranged for a summer meeting, which give it an individual character. The committee proposes that in addition to migratory convocation-week meetings during the Christmas holidays and meetings in sum- mer, it may be desirable to standardize other times and places for scientific meetings, more especially for meetings of committees, boards and the like. In many such groups, for exam- ple, in practically all the committees of the National Research Council, there are men work- ing in different sciences, and the cost and time of travel could be economized if several meet- ings were held on the same or consecutive days. We consequently suggest that it would be an advantage to scientific organization and research if committee and similar meetings were called in Washington in the fourth week in April; in New York City in the latter part of Thanksgiving week; in Chicago about the first of February, and in Wood’s Hole in August. This would give a convenient distribution both in time and place for such meetings. The committee does not regard convocation DECEMBER 1, 1922 week meetings during the Christmas holidays as necessarily final. There is much to be said for placing convocation week in the scholastic year, so that attendance at the meetings may be regarded both by teachers and administra- tors as part of the privileges and duties of scientific men. It is doubtful whether students would suffer by the absence of part of their teachers for a week, and it is certain that it would be to their advantage for their teachers to attend scientifie meetings. It is further the ease that neither midsummer nor midwinter is the best time for traveling or for the holding of meetings. Apart from inconvenience, dysentery in summer and colds in winter are a common sequence. A convocation week in autumn or im spring might be best for scien- tiie men and ultimately in the interest of the institutions with which they are connected. Tt is perhaps not necessary for the com- mittee to enter into a discussion of the advan- tages and disadvantages of large meetings. The inter-relations of the sciences are so fun- damental, however, that it is difficult to make separation in time and place of meetings of societies that is not inconvenient to some and perhaps adverse to the development of inter- relations that are important for the advance- ment of science. It is also the case that a large meeting may impress the magnitude and importance of science on the general public. In addition it may be noted that it is not so difficult either for executive officers or for hosts to arrange for one large meeting as for many small meetings, and there are other ex- irinsic advantages, such as reduced railway rates. On the other hand, it is desirable for men whose work is in the same science to meet ‘to- gether intimately, and the social arrangements for a small and isolated group are usually more agreeable than those for a large gather- ing. The compromise that has been worked out appears to be working with reasonable success, namely, that there be a general con- vocation-week meeting once in four years in three large scientific centers, Washington, New York and Chicago. In New York and Chicago, at least, there is ample ‘accommodation, so that societies can have headquarters and places of SCIENCE 619 meeting that will give them any desired degree of isolation. It might also be useful to arrange a twelve year schedule for convocation-week meetings of the second class, say, in Philadelphia, Balti- more, Pittsburgh or Buffalo four years hence; in St. Louis, Cincinnati, Columbus or Cleve- land eight years ‘hence; in Boston again, or in another New England city, such as Provi- dence, Worcester or New Haven, twelve years hence. Then it might be convenient to ar- range a provisional schedule for minor convo- cation-week meetings for the alternate years, including those cities mentioned when not selected for the twelve-year rotation and cities such as Montreal, Toronto, Albany, Rochester, Richmond, Louisville, Atlanta, Nashville, New Orleans, Houston, Indianapolis, Detroit, Kan- sas City, Omaha, Minneapolis, Denver, Salt Lake City, San Francisco, Los Angeles, Port- land and Seattle. The committee consequently recommends that all national scientific societies arrange to meet in Washington at the end of the year 1924, in New York in 1928 and in Chicago in 1932, and arrange their intervening meetings with a view to this program. The council of the American Association, which is primarily composed of representatives of the affiliated societies, will in accordance with its present policy arrange places of meeting that will be convenient for all societies for the intervening even years, namely, 1926, 1930, ete. For the intervening odd years the association will arrange a pro- gram for places of meeting to which the affili- ated societies will be welcome, but which will, as a rule, be in cities that are smaller and more distant from the center of scientific population. The meeting at the end of 1923 will be in Cincinnati. In \pursuance of these considerations the committee recommends the following resolu- tions for passage by the council: Resolved, That the greater convocation-week meetings of the American Association. for the Advancement of Science and the affiliated na- tional scientific societies be continued as for the past twenty years at four year periods in succes- sion in Washington, New York and Chicago, and that all national scientific societies be invited and urged to join in these meetings. 620 Resolved, That a corresponding twelve-year eyele of meetings for the intervening two-year periods be arranged for large cities in succession in the New England, the Central and the Atlantic States, in which it is desirable that the national scientific societies join. Resolved, That a provisional schedule of meet- ings in other cities for the odd years be arranged jn advance for the convenience of the scientific societies that may find it desirable to meet with the association. Resolwed, That arrangements be made for a summer meeting in 1923. Resolved, That scientific councils, boards and committees can to advantage hold their meetings in Washington during the fourth week of April, in New York at the end of Thanksgiving week, in Chieago on or about February 1, and in Wood’s Hole in August. Resolved, That Convocation-Week be the week in which New Year’s day falls when this is Thursday, Friday or Saturday; that when New Year’s day falls on Sunday, it be the preceding week, that when it falls on Monday, Tuesday or Wednesday, it begin two days after Christmas and continue into New Year’s week. J. McKeen CatTeLL Chairman FUNCTIONS OF THE DIVISION OF GEOLOGY AND GEOGRAPHY OF THE NATIONAL RESEARCH COUNCIL! Tue purpose of this paper is ‘to ask the geologists of the country what ought to be done with the National Research Council. I do not mean to imply that there is any trouble, or any disappointment, or that the right thing is not being done now. But the council is young, very young, and also very plastic, as it should be. It has the possibilities, and the dangers, of an infant. It may be well ito state first certain dangers that do The organization is not likely to die, in the sense of ceasing to exist. If it does there will be left a million dollar building bearing the words National Research not exist. 1 Published in advance to be discussed at a round table of the Geological Society of America at Ann Arbor, December 28. Discussion to be led by David White. SCIENCE [Vou. LVI, No. 1457 Council carved in marble along with the words National Academy of Sciences. In ‘the second place there is no immediate danger of its not having an organization and officers. The income from a few million dollars of per- manent endowment is enough to settle the ques- tion of continued éxistence in some form. So, for better or for worse, the National Research. Council is here, probably to stay. But what the council will be like in ten years or fifty years from now is what no man knows. When all foreseeable possibilities have been: assembled, they gravitate into two main groups. The council may become, on the one hand, a dispenser of “grants” or, on the other, an agency for promoting research in other ways,. mainly by stimulating, organizing or feder- ating the research activity which arises with- out grants. In either case money is paid out and research comes in, more directly in the former case, indirectly in the latter. One of the questions for the future will be whether research comes higher by direct purchase or by the more roundabout method. The above statements apply to the council ias a whole, but our own interest is in a single division, Geology and Geography, which is one of seven covering Science and Technology. It does not follow that ithe seven will, or ought to, develop alike. Exactly opposite divisional tendencies are among the possibilities and may even prove desirable. Before setting forth more fully the option which lies before geologists, it will be well to describe more exactly several of the possible functions of a national council of scientific men. On the approach of war in 1916-17 it suddenly became necessary to find out what was known and who knew it; also what had to be done and who could do it. It was mainly for such purposes that the National Research Council was organized under the Council of National Defense. The details of this war organization were not suited to itimes of peace, but the central idea held over, namely, that it paid to get scientifie men together in groups to take stock of what had been done and what is being done and to advise together concerning the things that remain to be done, especially those which ought to be done soon. DECEMBER 1, 1922] No other purpose can be so basic as this one of taking stock and surveying ithe field. It is the most essential business of men acting to- gether. As a corporate function it can stand on its own merits with or without other fune- tions. This step is worth while whether an- other is taken or not. This is the answer to the question—What can we do it we do nothing else? What is worth while 1f we can do only one thing? It is not yet certain to what extent this function will be realized by the council. If it is mot satisfactorily performed, then some future president of the United States may have ito send out another call as Lincoln did in 1864 and as Wilson did in 1916, asking scientific men to get together and tell us where we are at in science. The function thus described may hereafter be referred to as that of General Survey. Its inevitable complement is the giv- ing out of mformation. This double function is the basic duty of the Research Information Service. The figurative term “Clearing House” is often used and is not imappropriate. A second function is that of coordinating researches and of inspiring and organizing new ones. It is inevitable that any body of men performing the first function described above will be consulted by others who have problems on hand. About the first question a man asks when face to face with a new problem is: What has been done on this question by others? Who else is working on it now? If I am will- ing to do my share of ‘a task too big for one man, how can I get the other phases taken eare of? So the organizing and coordinating of work follows so naturally on the clearing house function that it would be difficult to keep out of it. A third line of activity is found in financing projects. Not all valuable projects require financing. Much valuable energy needs only organizing and coordinating. The council may be a vital agency with or without the financial function. In the original plan the financial function was nowhere distinctly specified; cer- tainly not regarded as essential. It will be well to explain here in just what sense the council or any one of its divisions may be said to be paying out money for re- SCIENCE 621 search. (1) The chairmen of the divisions of Science and Technology and other necessary officers are salaried. (2) Within certain limits, traveling expenses are paid. This applies to. officers on duty and ito members of divisions and committees in attending certain meetings of thei respective bodies; also in some cases to other men invited to participate in confer- ences on problems and projects. (3) A staff. of technical helpers is maintained for the clear- ing house work of the Research Information. Service. (4) When all the expenses of run-. ning the organization (not here enumerated), have been paid, there remains a moderate sum. to be allotted in small amounts to committees for the actual expenses of research. For the most part such sums are given merely to clear the way for starting projects which are ex- pected to be otherwise supported. The expres- sion “priming the pump” has been used, and deseribes the intention fairly well. The great bulk of the money thus far ex- pended under the auspices of the council has. been obtained by solicitation by and for the individual division or committee having change of a project. Generally the donor gives it for a specific purpose. Thus the responsibility for finding the money has been largely on the- men whose project was to be supported. It is. necessary to make this point clear, lest ithe im- pression should prevail that some men are beneficiaries of the Research Council in a sense: that other men are not. There is no scramble to “get in on the deal,” for when the pushers of a certain project have gotten in, they are still in large measure responsible for its sup- port. I say “in large measure”; it is of course true that they enjoy the advantage of having their project stamped with the approval of twenty or more representatives of their own science, picked from tthe nation, and with the further approval of a body representing all sciences, whose business it is to distinguish the most worth while from the merely desirable. In addition jto this advantage, there is some- times some actual aid in solicitation by the general officers of the council and a special committee on Funds and Projects. These are the only ways in which money is 622 dispensed for research. It should be plain from this that the democratic or representa- tive character of the council, designed, as it was, to express ‘the combined judgment of scientific workers, is not in any way impaired by the function of making “grants” or select- ing a list of “beneficiaries.” If the council is ever to become a dispenser of funds, the change would no doubt come about through such a growth of confidence in its work that much larger donations would be made with less and less question as to their use. It is not impossible ‘that this will occur, but the indications that point that way do not affect our division and need not be mentioned here. As tthe great question before the geologists of our country is the use which they can make of their own division, and as the possibility of raising money is often a part of that question, it will be wise to examine briefly the sources of ‘the support thus far obtained for other pur- poses. The several scientific divisions differ enormously in the financial support which they have been able to command. Should this dif- ference be regarded as a measure of efficiency or merely as an indication of difference in method? Ought Geology and Geography with equal leadership and diligence to have cap- tured their “share” of the more than half a million dollars donated for Physies and Chem- istry, or of the like amount given to Medi- cine? These questions may not be answered positively, but it will help some if we inquire what relation the donors have borne to the ob- jects of their donations. In other words— What has been the nature of the “appeal” in each case? When we have finished this anal- ysis we may ask whether Geology should be going to its friends with similar appeals. The largest donations have come from cor- porations holding large trust funds whose income must be distributed. Each one of these corporations specializes more or less in certain fields of science and generally elects to make its donations in fields related to its central interest. Thus tthe Rockefeller Foundation is known ito be interested in Medicine and its con- tributory sciences. In addition to the five mil- SCIENCE [Vou. LVI, No. 1457 lion dollars given by the Carnegie Corporation for endowment and building, well over a mil- lion dollars have been pledged for research by various trusts of similar character. Another lange class of donations, aggre- gating ito date a few hundred thousand dollars, have had for their object some improvement of technique of manufacture or other ultimate ad- vantage in production. The donors to such projects generally represent commercial inter- ests in the corresponding fields of industry. The researches subsidized are of fundamental character but their relation to industry or trade is sufficiently patent to afford a strong appeal to producers. Examples of this class are found in the donations for the Critical Tables of Physical and Chemical Constants and in the support of the Crop Protection Fellowships. A slightly different appeal, looking toward preservation rather than production, is found in the support of the Marine Piling Investiga- tion. A smaller amount must be credited to pure philanthropy or public spirit. In these cases the donor can hope for no return in the way of personal profit, as when a great retail mer- chant gives the money for a biological fellow- ship. While less than one hundred ‘thousand dollars given directly to scientific work comes under this classification, it is fair to mention the one hundred and eighty-five thousand dol- lars contributed by twenty friends to purchase the site for the building. ‘ Lastly, a few thousand dollars have been contributed by states toward cooperative re- searches, such as reforestation and highway problems. The appeal here is for state aid in what is properly a state function. With this classification of donors and ap- peals before us, geologists should ‘be able to run down the list and form some idea whether their science is in position ‘to make effective appeals for money. The list of great trusts is not long and the general field that each one favors is known. Geology is by no means ex- eluded from ‘their interests (recall, e.g., the Carnegie Corporation and the Shaler Memorial Fund) but in no ease is it likely that the National Research Council would be asked to DrEcEMBER 1, 1922] handle their donations. If the measure of use- fulness of a division is found in the funds it handles, this would be discouraging. If, on the other hand, the division is primarily inter- ested in seeing the science advance, the situa- tion may be quite ideal. Illustrations might be given of projects first fostered by the Divi- sion of Geology and Geography and then “turned over” to other agencies. Is there anything in the field of Geology analogous ‘to the interests which manufac- turers have in the improvement of production through study of fundamental principles? Could mining men be asked to get together and finance a study of structural geology or geo- chemistry? To put down the answers which these questions suggest would take more space than is permitted. The most obvious answers would not encourage such hopes for the im- mediate future. Can we appeal to men on the basis of pure public spirit or scientific interest? Certainly Geography does this, if exploration may be called geographic investigation. It is quite true that money thus donated might not gen- erally pass through the hands of the National Research Council, but that is a mere detail so long as the Council inspires the undertaking. Almost the same may be said of state and federal funds. Little if any of this will ap- pear on the accounts of our division, but it would be surprising and ought to be disap- pointing if we do not influence the work of official surveys even to the extent of inducing them in some cases to take up definite projects. The general impression from such a casual analysis might be that our division can not well expect to be asked to administer large donations for geologic research. More largely than any other science, Geology is regarded as a governmental function and no one likes to subseribe to a governmental deficit. An ob- server from the outside might say that Geology is already pretty well supported. Of course geologists know it is mot. But ours is not the only family whose poverty is known better inside than outside. As for Geology in private employ, largely in mining and drilling, there remains a pecu- liar assumption of private interest and the SCIENCE 623 value of secrecy. The pooling of interests to support researches in basic problems has not gone so far among mining men as among steel manufacturers, as the Research Council and the Engineering Foundation have good reason to know. On the other hand the United States Geo- logical Survey and some state surveys, despite all we say when our humor is bad, do provide deliberately for some research in pure science, and the by-product of pure science from both public and private work is large. The nature and amount of such by-products is determined largely by individual interests, as at should be. But it would be all folly to deny that there is much fine enthusiasm resulting in scattered and sometimes fruitless effort; mere lost mo- tion. There are strategic points and timely moves in science as in war. The kind of guidance that comes from cooperation and the fullest possible knowledge of what others are doing ought to be profitable. Can the Re- search Council supply these elements? The situation here referred to is exemplified in the work of our committee on Sedimenta- tion. A few years ago it was tacitly assumed that the manner of origin of sedimentary rocks was completely stated in our elementary texts. Then individual workers began to raise ques- tions. Interest appeared at many points and contributions began. When ‘the Research Council was reorganized on a peace basis one of the first demands made on this division was that it organize the study of ‘Sedimentation. The result has been a tripling of the work and, better still, a conscious planning ito send work- ers into ithe darkest parts of the field. Other sciences have been drawn on for assistance. Men have been newly inspired by finding that their own little studies were highly useful in a big problem. The work may go on a few years more. ‘There is little doubt that, fifty years hence, men will point back to ‘the decade em- bracing these researches as a time in which the study of sedimentary rocks was raised to a new scientific level. Now a point to be emphasized is that the Research Council is paying out no money for this research except for occasional conferences. The work is being done by skilfully appropri- ‘624 ating the opportunities offered by surveys and universities. It can scarcely be said that men have left other studies for this work. In most eases they have merely been asked to direct their efforts toward a certain point, or to have in mind their bearings on another principle. Having set forth something of various ways in which the Research Council works, it should ‘scarcely be necessary to guard scientific men against certain misconceptions. There have deen such and they have done some harm. The first of these possible misconceptions is that the council was designed to superintend research workers and see that they did the right thing; perhaps to assign problems to this and that man and to tell others what fields to keep out of. Such a situation is purely imag- inary. No doubt some newspaper writers, not kmowing the ways of science, did give utiter- ance to such dreams, but ithey should not have deceived scientific men. Another assumption, less absurd but just as wrong, is that the council is an “institution” @arrying on researches on its own account. It has no laboratories, not even a library, except a few reference books. It hires no investiga- tors. It is merely a mode of cooperation. There is something almost fallacious about speaking of the Council as “it”; there is no it; nothing but we. The council does nothing ex- cept what men in groups have always been trying to accomplish. The only valid claim is that men’s combined efforts are being spent ‘to better advantage. Geologists always have con- ferred, analyzed their problems, cooperated and looked around for help. The only ques- tion ‘before us is whether such activities can be facilitated by a bit of machinery for confer- ence, correspondence, record keeping and ad- ministration. To guard against misunderstanding it should be stated explicitly that it is highly desirable that the Division of Geology and Geography should have funds for its own projects. But the poimt which needs emphasis just now is that the thing which is to justify the existence of the Research Council is something quite different. When the geologists of our country have definitely adopted the National Research SCIENCE [Vou. LVI, No. 1457 Council as a mode of operation they should by all means undertake to enlarge its usefulness by financial aid. Nevin M. FennNemMAn NATIONAL RESEARCH COUNCIL, Wasuineton, D. C. NATIONAL RESEARCH COUNCIL'S MEDICAL FELLOWSHIPS Har.y this year the Rockefeller Foundation and the General Education Board jointly pledged to the National Research Council for the administration, through its Division of Medical Sciences, of medical fellowships the total sum of $500,000, payable annually through a period of five years in sums not to exceed $100,000 a year. A special board for administering these fel- lowships was selected with the approval of the National Research Council and the two foun- The board is composed of tthe follow- ing members with 'the chairman of the Division of Medical Seiences of the Natiional Research Couneil (at present Dr. F. P. Gay, professor of bacteriology, University of California) as chairman, ex officio; David L. Edsall, pro- fessor of medicine and dean of the Medical School, Harvard University; Joseph Erlanger, professor of physiology, School of Medicine, Washington University, St. Louis; G. Carl Huber, professor of anatomy and director of the anatomic laboratories, University of Michi- gan; E. O. Jordan, professor of bacteriology, University of Chicago; W. G. MacCallum, pro- fessor of pathology and bacteriology, Johns Hopkins University; Dean D. Lewis, professor of surgery, Rush Medical School, Chicago; La- fayette B. Mendel, professor of physiological chemistry, Yale University; W. W. Palmer, professor of medicine, Columbia University. This board met for the first time on April 18, 1922, and in this and subsequent meetings outlined certain regulations that should govern their decisions in connection with the appoint- ment of fellows and the method and place of their work. Since that time two additional meetings of the board have been held for the purpose of appointing fellows from the list of dations. DECEMEER 1, 1922] applications that have been received. The most essential points decided upon by the board are the following: (1) The fellowships are designed primarily for research as fundamental to a teaching career in one of the medical sciences. For this latter reason it is prescribed that the fellow must work where facilities for, but not obligations in, teach- ing are afforded. (2) The fellowships are for full time and basal salaries of $1,800 for unmarried men and $2,300 for married men have been determined. Salaries in either of these grades may be larger than the minimum, depending upon the number of de- pendents and the locality chosen by the candidate for work. (3) The place of work and the subject chosen for investigation are determined by the candidate with due consideration for the feasibility of the plan proposed. It has been decided that the work may be carried out either in this country or abroad. The first fellows have been appointed and are now at work. In spite of the fact that the funds for these fellowships generously donated by the Rockefeller Foundation and General Education Board were not available and that announcements concerning the fellowships could not be made until relatively late in the year numerous applications have been received and twenty-six candidates have already been accepted. The fellows so far appointed cover the whole group of the specialities of medicine and are divided as follows: Pathology and bacteriology.................... 5 Mie dicin el) tee tes e hs ahr sas eo ese ws teecetee acts 5 SUT C Tey syed ere ET ee ee 6 IP NyS1OLO preys yee ees cae EY 4 Biochemistriyp tee tes eee eae isaeanes 2 FeNG EBON EN Ae 1 Medieal specialties 1 Pharmacology ......... aa Physical chemistry 4 al The work is now being carried out in various medical centers as follows: Harvard Columbia...

SCIENTIFIC EVENTS THE INTERNATIONAL COMMISSION OF EUGENICS As has been noted in Science, the Inter- national Commission of Eugenics met at Brus- sels on Saturday, October 7, and Monday, October 9. According to the report in Lugeni- cal News, there were present Major Leonard Darwin, chairman; Dr. Almert Govaerts, sec- retary; Dr. Van Herwerden of Utrecht, Hol- land; Dr. Winner, Professor of psychiatry, Copenhagen; Dr. Jon Alfred Mjoen of the SCIENCE [Vou. LVI, No. 1457 Winderen Laboratorium, near Christiania, M. Lucien March of “Statistique générale de la France,” and Dr. Pinard, President of the Société Francaise d’Hugénique, Paris; and Dr. C. B. Davenport, of Cold Spring Harbor. It was voted unanimously to invite German delegates to the commission. It was decided provisionally to hold the next meeting of the commission at Lund, Sweden, and the next meetings of the Eugenics Congress in 1924 at Prague. ‘These decisions are contingent upon the possibility of making appropriate arrange- ments for the meetings. The occasion of the meeting of the Inier- national Commission of Eugenics at Bruxelles was taken advantage of for a meeting of the Ligue nationale Belge contre le Péril vénérien at the same place, and an extensive social pro- gram was arranged. On October 7, a lecture was given by Dr. Apert, physician of the hospitals of Paris, en- titled, “L’Hérédité Morbide.” On October 8, in the morning a joint congress of the Ligue contre le Péril vénérien and Fédérations of Anti-Aleoholic Societies of Belgium was held in collaboration with the Belgian Hugenics So- ciety. In the afternoon there was an excur- sion to Waterloo, where an address was given by M. Gheude, député permanent, entitled, “Les buts Eugéniques de Ja Ferme-Ecole.” This was followed by visits to the battlefield and to the Ferme-école Provinciale, the new home for the feeble-minded which it is hoped will be ready for occupancy in the spring. On Monday, there was held the second meeting of the commission, and, at 4 o’clock, a visit to the Solvay Institute of Sociology where Major Darwin gave an address entitled “L’Hugénique” and Professor Wimmer of Copenhagen one on “Mental Heredity.” At 5 o’clock, the Prison de Forést and its laboratory of anthropology were visited. On Tuesday, addresses were given by Dr. Daisy M. Robinson, by M. Lucien March, of Paris, and Dr. Berthollet, of Lau- sanne, on matters partly of anti-veneral and partly of eugenical interest. At half past two in the afternoon, a meeting was held in the large hall of the Solvay Institute of Sociology, at which was inaugurated the eugenics room DEcEMBER 1, 1922] of the institute. Two lectures were given on the practical organizations of eugenics, “in the United States” by Dr. Davenport; “in Bel- gium” by Dr. Govaerts. On Wednesday a visit was made by the Congress to the city of Antwerp. THE FEDERATION OF AMERICAN SO- CIETIES FOR EXPERIMENTAL BIOLOGY Tur 1922 annual meeting of the federation will be held on Wednesday, Thursday and Friday, December 27, 28 and 29, at Toronto, Canada, under the auspices of the University of Toronto. The program will be sent out about December 14. An effort to secure special railroad rates is being made. In case these are secured members will be notified. The hotel headquarters are the King Edward. About 100 men can be accommodated, in either single rooms or in suites each with two bedrooms, in ithe men’s residences of the university. About 12 women can be accommodated in one of the women’s residences. Breakfast for those living in the residences can be obtained at Hart House. ‘The charge for these rooms will be $3.00 for 3 nights, or $2.00 for 2 or 1 night. Luncheons will be provided on the 27, 28, and 29. Dinners will be followed by a smoker on the evenings of the 27 and 28. All these will be given in Hart House, the stu- dent’s club, near the residences and the medi- cal building. The Local Committee is anxious to arrange a large series of demonstrations. As the de- partments of physiology, biochemistry and pharmacology are all in the one building, fa- cilities of all kinds can readily be arranged. All communications in regard ito the same should be addressed to Professor J. M. Olmsted, Medical Building, University of Toronto. The general meetings will be held in the Physies Building of the university. Meetings of the Constituent Societies will be held in the Medical and Anatomy Buildings of the univer- sity, which intercommunicate. The lecture rooms are not distant from each other and it is hoped to have a notice board system, so that the papers to be read in each section will be SCIENCE 627 posted in each other section. Professor An- drew Hunter is chairman and Professor V. H. Henderson is secretary of the local committee. THE AMERICAN PHYSICAL SOCIETY Tue 24th annual meeting (the 118th regu- lar meeting) of the American Physical So- ciety will be held in Boston on December 26- 30, 1922, in affiliation with Section B—Physies —of the Ameriean Association for the Advance- ment of Science. The meetings will be held at the Massachusetts Institute of Technology. At the session in charge of Section B, Pro- fessor G. W. Stewart, the retiring vilce-presi- dent and chairman of Section B, will give the annual address. This will be followed by a symposium on “Jonization Potentials and Atomic Radiation,” and the invited speakers are to be Dr. Paul D. Foote, of the Bureau of Standards, and Professors K. T. Compton and Henry Norris Russell, of Princeton. Members wishing to present papers at the Boston meeting are requested to send abstracts ready for publication to tthe secretary before December 9. The secretary expects to send the program to all members before the meet- ing, but the delays in the mails are so great at present that members should not depend upon the program to determine their attend- ance. Other meetings for the current season are as follows: 119. February 27, 1923. New York. 120. April 21, 1923. Washington. 121. Time not determined. Pacifie Coast Section. Dayton C. MILLER Secretary Case ScHoot or APPLIED SCIENCE, CLEVELAND, OHIO THE MATHEMATICAL ASSOCIATION OF ; AMERICA THE seventh annual meeting of the Mathe- matical Association of America will be held at Room 11, Sever Hall, Harvard University, December 28-29, 1922, in conjunction with the American Mathematical Soaety and Section A of the Ameri¢an Association. At a joint ses- sion of these three bodies the following papers will be read: 628 Reduction of singularities of plane curves by birational transformation: Proressor G. A. Buiss, University of Chicago, retiring president of the society. The grafting of the theory of limits on the calculus of Leibniz: Pxorrssor FiLor1an Cagort, University of California, representing the asso- ciation. Geometry and physics: Prorrssor OSWALD VEBLEN, Princeton University, retiring vice- president of Section A of the American Associa- tion. At the Friday morning session the follow- ing papers will be given: Period of the bifilar pendulum for finite ampli- tudes: Prorrssor H. 8S. Unuer, Yale University. Skew squares: Proressor W. H. Ecuous, Uni- versity of Virginia. On the averaging of grades: Prorrssor C. F. GUMMER, Queen’s University. ; Mathematics at Oxford and the Ph.D. degree: Proressor W. R. BuRWELL, Brown University. Some unsolved problems in the theory of sampling: PRoressor B. H. Camp, Wesleyan Uni- versity. Some unsolved problems in solid geometry: Prorrssor J. L. Cootwwer, Harvard University. It is of special note that the session on Friday afternoon will be devoted to a “Sympo- sium on Mathematical Statistics,” for the pur- pose of strengthening the existing entente cor- diale between mathematicians on the one hand and practicing statisticians on the other. It is hoped that this symposium will be of real service, not only to ‘those who are giving courses in statistics in departments of mathematics, but also to others who may be interested in the application of mathematics to statistical prob- lems. The following papers will be read: The subject matter of a course in mathematical statistics: PRroressor H. L. Rimrz, head of the department of mathematics at the State Univer- sity of Iowa, and chairman of the National Re- search Council’s Committee on the Mathematical Analysis of Statistics. Time series of economic statistics: their fluc- tuation and correlation: Warren M. Prrsons, professor of economics at Harvard University, and editor of the Review of Economic Statistics, published by the Harvard Committee on Eeo- niomic Research. The fundamental concepts of the calculus of mass variation: ARNE Fisuer, statistician of the American Telephone and Telegraph Company, and SCIENCE [Vou. LVI, No. 1457 author of ‘‘The mathematical theory of proba- bilities and its application to frequency curves and statistical methods.’’ The discussion will be opened by RayMoNnD PEARL, professor of biome- try and vital statistics in the School of Hygiene and Publie Health, Johns Hopkins University, and statistician of ithe Johns Hopkins Hospital. CHEMISTRY AT THE BOSTON MEETING OF THE AMERICAN ASSOCIATION Tue Boston meeting of the American Asso- ciation for the Advancement of Science will undoubtedly be the most important to chemists of any of its meetings held for years. Papers on research work completed or in progress are now invited from the chemists of the country. In addition to such papers as may be sub- mitted there will be a symposium on “The Progress of Chemistry,’ and a second sym- posium on “Photochemistry and Plant Physi- ology,” in which the leading chemists of the country will discuss these subjects. In ad- dition the American Physical Society will con- ‘tinue the series of symposia begun last year jomtly with the Mathematica and Chemical Societies. The subject will be “Ionization Potentials and Atomic Radiation,’ and the speakers will be Paul D. Foote, K. T. Comp- ton and Henry Norris Russell. The following list gives the papers already arranged for in connection with the symposium on the progress of chemistry: “Compres- sibilities and the size of atoms,” by Theodore W. Richards, of Harvard University; “Pro- teins and the theory of colloidal behavior,” Jacques Loeb, of the Rockefeller Institute; “X-rays as related to ithe structure of atoms and of crystals,” Wiliam Duane and also George L. Clark, both of Harvard University; “Changes in volume during the solution of solids,” Gregory P. Baxter, of Harvard Uni- versity; “The chemistry of the photographic process,” C. EH. K. Mees, of the Hastman Kodak Company; “The present status of the theory of complete ionization,” D. A. MacInnes, of the Massachusetts Institute of Technology; “The present status of the theory of incomplete lonizaion,” James Kendall, of Columbia Uni- versity; “Ionization potentials and chemical action,” W. A. Noyes, Jr., and “The separation DrceMBER 1, 1922] of isotopes,’ by R. S. Mulliken, both of the University of Chicago. In addition a number of other topics, not yet fully decided upon, will ‘be discussed by noted chemists. At the symposium on photochemistry and plant physiology to be held Thursday, Decem- ber 28, at 2 p.m., H. A. Spoehr, of the Desert Laboratory, will discuss “Photosynthesis,” S. E. Sheppard will speak on “Photochemical re- actions,” and a third speaker will present the subject “Carbohydrate metabolism.” The address of the retiring vice-president and chairman of Section C will be upon the subject “The muclei of atoms and the general system of isotopes.” It is expected that one or two of the ses- sions will be provided with a program by nearby sections of the American Chemical So- ciety as follows: the Nontheastern, the New York, the Eastern New York, the Cornell, the New Haven, the Philadelphia, the Washington, and the Delaware sections. Speakers have been invited to present papers on atomic structure, the electron theory of valence, the nature of metals, the work of various great laboratories, and various other topics of interest to professional chemists. It should be noted that no specific invitations have been sent out for papers on the research work of individuals, but it is hoped that the chemists of the United States and Canada will respond in considerable numbers to the general invitation given in the present notice. The titles of such papers should be sent as soon as possible either to the retirmg chairman, Professor W. D. Harkins, of the University of Chicago, to the secretary of the Northeastern Section of the American Chemical Society, Professor HE. B. Millard, of the Massachusetts Institute of Technology, Cambridge, Mass., or to the vice-president and chairman, Professor W. Lash Miller, of the University of Toronto.

The lectures, which are open to the pub- lic, were begun during the session before the war. Amv Lake Forest College there has recently been reorganized a Science Club, which has been dormant since the departure of Dr. James G. Needham in 1901. The departments of chemistry, biology and psychology are sponsors for the club and supervise the bi-weekly pro- grams, the punpose of which is to stimulate in- terest in the general problems of the three fields. All persons in the vicinity interested in science are invited to attend. The follow- ing are the topies and leaders for the first three meetings: “Hypnotism,” by Dr. W. R. Wells; “The tropism ‘theory as a basis for the interpretation of human behavior,” by Dr. W. H. Cole, and “The constitution of matter,” by Dr. F. B. Coffin. Tue three concluding addresses in the series of illustrated evening lectures given this autumn by the Carnegie Institution of Wash- ington, are as follows: November 28, “The con- stitution of the hereditary material and its relation to development,’ Dr. T.

Those desiring to take part by exhibiting apparatus, materials, ete. should communicate at once with Professor R. P. Bigelow, Massachusetts Institute of Technol- ogy, Cambridge, Massachusetts. Professor Bigelow is chairman of the subcommittee on exhibits for the Fourth Boston Meeting. APPLICATION has been made for reduced rail- road fares, on the certificate plan, for persons attending the annual meetings of the Geological Society of America, the Paleontological So- ciety, the Mineralogical Society of America, the Society of Economie Geologists, the Asso- ciation of American Geographers and the American Association of State Geologists, in Ann Arbor, Michigan, December 26-31, 1922. When purchasing tickets-at the regular one- way fare, certificates of the standard form should 'be obtained from the railroad ticket agent. The granting of return tickets at one half the regular fare is conditional upon there being 250 persons in attendance upon the meetings who hold certificates showing that they have paid 67 cents or more on the go- ing trip. For the purpose of commemorating the serv- ices of William Thompson Sedgwick to the cause of biology and public health, there has ‘been established a memorial lectureship in the depariment of the Institute of Technology which he created. The desire of the founders is that the Sedgwick Memorial Lectures shall be given from year to year by men of dis- tinguished eminence in any one of the sub- jects comprehended within the general scope of biology and public health in order that it may fittingly express the deep and broad sym- pathy of the man whom the lectureship is de- signed to honor. The committee in charge of the ledtureship consists of Samuel C. Prescott, Massachusetts Institute of Technology; Edwin 632 O. Jordan, University of Chicago; George C. Whipple, Harvard University; Gary N. Cal- kins, Columbia University, and Charles-K. A. Winslow, Yale University. The first William Thompson Sedgwick Memorial Lecture will be given in Huntington Hall, 491 Boylston Street, Boston, on Friday, December 29, at five o’clock, by Dr. Edmund Beecher Wilson, Da Costa professor of zoology at Columbia University, on “The physical basis of life.” The lecture will form part of the program of the meeting of the American Association for the Advance- ment of Science, the American Society of Naturalists and other societies during econvo- eation week. Ir is announced from Stockholm that since it has been decided not to award the Nobel Prize for Medicnie for 1921, ithe prize will be added to the Special Medical Fund. The 1922 prize is reserved for next year. Tre Méthane Association, organized in 1916 with the object of advancing industrial chem- istry in Poland, has been reorganized as an Institute of Research, and Professor Moscicki has been appointed director. The government of Poland has made a grant of land in the neighborhood of Warsaw, where buildings for the institute will be erected. Winuiam Eastman Stanpow, a graduate of the University of Denver and a graduate stu- dent at Columbia University, was killed by an explosion in the chemical laboratory on No- vember 17, through the explosion of a chamber containing aniline hydrochloride. PROFESSOR JEREMIAH Gxoras Mosizr, for twenty years in charge of the work in soil physies at the University of Illinois, died on November 10, 1922, at the age of sixty years. A correspondent writes: Professor Mosier gradu- ated from ithe University of Illinois in 1893. He then became an assistant in geology in tthe same institution, in which position he served for three years. After a period spent in high- school teaching he reentered the service of his university in 1902 to take up the work in soil physics, a subject which at that time was largely undeveloped. Professor Mosier was an unusually inspiring teacher and he has won the love and respect of the hundreds of stu- dents who have come under his instruction. In SCIENCE [ Vou. LVI, No. 1457 his field of investigation his interest was broad; but some of the problems which engaged his especial attention were the prevention of soil washing on hilly land, the effect of cultivation, climatological observations, and the soil sur- vey of Illinois, upon all of which topics he made notable published contributions. Pro- fessor Mosier’s chief interest lay, perhaps, in the soil survey of Tllinois, he having been in direct charge of the mapping since the begin- ning of the survey. Under his direction about four fifths of the state have been mapped. Through his long experience in this connection, he acquired an expert knowledge of soil types that made of him a widely recognized authority in soil classification. UNIVERSITY AND EDUCATIONAL NOTES THE $1,600,000 financial development pro- ject for Dickinson College and Pennington Seminary has been brought to a successful con- clusion. Of this amount, Dickinson, it is re- ported, will receive $1,250,000 and Pennington $350,000. The money will be used for build- ings, betterment, liquidation and endowment. Grounp has been broken for the new labora- tory of the department of hygiene and bac- teriology of the University of Chicago, which when completed will be devoted to bacteriologic and chemical research. It will be erected at a cost of $50,000. Unvber the will of the late Sir Wiliam Dunn a further sum of £45,000 now accrues to the School of Biochemistry of the University of Cambridge, making a total gift for the pur- pose of the school of £210,000. Paut Martyn Lincotn, of Cleveland, Ohio, has been elected professor of electrical en- gineering and director of the School of Hlec- trical Engineering in Cornell University. Pro- fessor Lincoln, who is a practicing engineer, was professor of electrical engineering at the University of Pittsburgh from 1911 to 1915. He was president of the American Institute of Electrical Engineers in 1914. CuHartes Hartan Apsort, Pu. D. has re- signed his position at the Massachusetts Agri- cultural College to accept the professorship of DECEMBER 1, 1922] zoology at the University of Redlands, Cali- fornia. Dr. J. R. Currie, a senior medical officer of the Scottish Board of Health, has been ap- pointed to the chair of preventive medicine in Queen’s University, Kingston, Ontario. Dr. H. Strantny ALLEN, of the University of Edinburgh, has been appoimted to the chair of natural philosophy in the United College, St. Andrews, which has become vacant by the retirement of Professor Butler. DISCUSSION AND CORRESPOND- ENCE FINANCIAL SUPPORT OF TECHNICAL JOURNALS It is a not uncommon practice for members of the faculties of our colleges, universities, and other schools to enrich ithe libraries of these institutions by donating copies of technical journals received by tthe individual either by subseription or by virtue of membership in some scientific society. This loyalty to ithe local institution is natural and laudable from the standpoit of the institution, but it may, per- haps, not be realized that if every one of our colleges and universities were to depend upon such gitts for their files of scientific periodicals there would shortly, in the case of many such publications, not be any journal ‘to donate, so inadequate is the financial support of scientific publications. With the exception of ‘those journals, such, for example, as the chemical journals, which have a large and financially profitable circula- tion among practical workers outside of h- braries and faculties, many of our journals de- voted to pure science are barely, or not at all, able !to exist except for generous subsidies. Outside of members of societies of which the publications may be the official organ, paid subscriptions may be expected only from a very few individuals not members, from a very small number of public libraries in our larger cities, and from educational institutions. It is a matter of record that many of our journals devoted to publishing the results of research do not have subscriptions from more than a small fraction of American institutions SCIENCE 633 maintaining a department in the given science, and in many cases {this results because some member of the departmental staff contributes his personal copy to the library. One of our biclogical journals recently faced the necessity of either securing a generous ad- ditional subsidy, or of increasing its subserip- tion rate by one dollar a year, or of suspend- ing publication. The subsidy was not forth- coming and so the subscription price was ad- vanced. Notice to this effect was followed by cancellation of subscripition, not by one of our private, struggling, small colleges, but by one of the largest of our state universities. The letter of cancellation stated that the institution would hereafter depend upon a donated copy. The existence of all of the journals of the class referred to is a matter of vital importance to the colleges and universities. None of them is maintained for its own sake as a business venture. Practically all of them were estab- lished because of the impossibility of securing the publication of the results of research with any degree of promptness—often not within a year or eighteen months, or even longer, afiter the completion of the manuscript. Our colleges and universities should regard practically all of these journals as established primarily for their advantage, and the journals in turn are justified in expecting support from these institutions ito the extent of at least one subscription. The donation of personal copies by professors to the library of their institution may help the library to the extent of a few dollars, but the present extent of this practice is depriving journals, indispensable to donor and benefactor alike, of hundreds of dollars each of support annually. It is an imteresting but regrettable fact that, while it is comparatively easy to obtain money for research, nothing is much more difficult to seeure funds for than the publication of the results of research. C. Stuart GaGcer ACOUSTICAL RESEARCH THE quotation from the London Times on tthe subject of Acoustical Research (November 3, 1922) conveys an impression which seems to need correction. 634 In justice to the life-long labors of the late Professor W. C. Sabine, now gathered into a volume of Collected Papers on Acoustics (Har- vard University Press), it should be said that the practical problem of predicting the acous- tics of an ordinary auditorium in advance of its construction, or of correcting one already. built, was solved by Professor Sabine some twenty years ago. The essential feature to be considered in such a problem is the reverbera- tion and Sabine’s papers on ithis subject are full and complete. Other acoustic questions are, of course, sometimes involved such as the transmission of sound through walls, the effect of resonance, ete. Several of these had also been ‘the subject of prolonged experimental in- vestigation by Professor Sabine at the Jeffer- son Physical Laboratory at Harvard but some of the results were withheld until the work could be completed. His untimely death in- terrupted this program, and since then tthe work has been continued here and at the Acoustical Laboratories at Riverbank, Elinois, under the direction of Dr. Paul E. Sabine, as described in Mr. Munby’s article in Nature, October 28, 1922. Architects in this country have become aware of the importance of Sabine’s results and scores of eases could be cited in which the appliea- tion of the principles worked out by him has Jed to complete success. The opinion that “Architects are still unable to predict with cer- tainty ‘the acoustic properties of the halls and «chambers they design” implies a lack of ‘re- spect for Sabine’s profoundly accurate and thorough work which I am sure no one will maintain who has taken the trouble to acquaint himself with ‘the subject. THEopoRE Lyman, Director JEFFERSON PHYSICAL LABORATORY, HLARVARD UNIVERSITY AUSTRIAN SCIENTIFIC PUBLICATIONS To tHe Epiror oF Science: The present financial difficulties of scientifie and technical journals have no doubt come to ‘the attention of many readers of Scimrncr. I am tempted to eall their attention to a specific case by quoting SCIENCE [Vou. LVI, No. 1457 a recent letter from William Ford Upson, American trade commissioner in Vienna: On a pathetic appeal of Professor Wilhelm Exner, an eminent Austrian scientist, president of the Technisches Versuchsamt, I am sending to the Bureau of Standards, with my compliments, the Mitteilungen des Technischen Versuchsamtes for one year. The publication is in sore straits for lack of funds and its ambition is to get 100 foreign subscriptions at $1.00 per year each, to. enable it to continue publication, but its efforts have proved unavailing except that I am sending out a few copies at my own expense. Could you help in the good work in any way? The Bureau of Standards is already a sub- seriber to this publication, but I trust that the above appeal will put other research laborato- ries or libraries on the subscription list. Wiuuiam F. Mracers BUREAU OF STANDARDS AN APPEAL One hundred Russian university and profes- sional men, mostly scientists, many of them internationally famous, recently exiled from Russia by the Soviet government, are in Ber- lin im serious circumstances. Local charity is housing and feeding them, but they lack sufficient clothing, shoes and pocket money ito get through the winter without acute dis- tress. An appeal has come to the American Re- lief Administration for one thousand dollars to provide some relief (averaging only $10 a man) for these exiles. Unfortunately all of the A. R. A. funds must be spent for relief inside of Russia. .The appeal has been turned over to me. Will the scientific men of America help these suffering scientific men of Russia? A generous friend, Princess Cantacuzene, of © Washington, has given me one half ($500) of the sum needed. I shall be glad to be one of fifty to give $10 each, or one of one hundred to give $5 each, to make up the other half. I will undertake to receive the gifts and send personal receipts for them, and later obtain and publish in Scrmncg a blanket receipt from Berlin for the whole amount received and sent over-seas. ue VERNON KELLOGG NationaL RESEARCH COUNCIL, WASHINGTON, D. C. DECEMBER 1, 1922] SPECIAL ARTICLES ORGANIZATION OF HETEROTYPIC CHROMOSOMES In a recent article H. C. Sands! gives a pre- liminary account of his interpretation of chromosome structure in Tradescantia. This ac- count seems to differ much in fundamentals from the results of a study conducted by the writer on various species of the South African Liliaceous genus Gasteria. To ‘consider only the most interesting’ feature, the heterotypic chromosomes, we find first that at metaphase there are three pairs of small chromosomes in the center of the plate, with four pairs of much larger ones arranged in radiating fashion around them. In favorable material it is easy to see that the metaphase chromosomes are organized internally into chromomeres, though these are somewhat irregularly arranged. Even before they separate the larger chromosomes each show a cleft at the outer end opposite the fiber attachment, and before anaphase is far advanced they are nearly completely divided longitudinally into two halves. Usually this is entirely completed before telophase sets in, and the halves are widely separated. The smaller chromosomes are slow to split, but finally do so. Consequently there is at telo- phase a diploid number of separate chromo- some-halves and the homotypic division has been prepared for. As the larger chromosomes separate in ana- phase it is clear that in each half-chromosome there is a double row of rounded chromomeres. These are few and apparently quite definite in number, well separated from each other and stain sharply in contrast to the almost colorless matrix. As the membrane first ap- pears around the group of telophase chromo- somes (which are well separated in this genus and easily studied) it becomes evident that there are no longer two rows of chromomeres, but that four are now present. When the chromosomes are obliquely placed these can clearly be distinguished, especially in the later stages when the chromosomes begin to broaden at the ends in preparation for a more even dis- tribution of the chromatin in the interkinetic nucleus. The smaller roundish chromosomes 1Sands, H. C.: ‘‘Perigenesis,’’ Screncr LVI, 517-518, 1922. SCIENCE 635 show comparable changes, though less clearly because of their size. It would seem that this can only mean that both the gametophyte divi- sions in the pollen grain have been completely prepared for. The chromomeres which enter the construction of the sperm nuclei seem to be already formed and merely awaiting ithe me- chanical distribution of these mitoses. Unfor- tunately it has mot been possible to trace the history of the chromomeres as such through these two divisions. By a method based on smear preparations it has been possible to largely confirm the re- sults of sectioned material and to obtain fixa- tions in. which synizesis (synapsis) has been almost entirely eiminated. The best results on the anaphase and telophase stages were ob- tained when the dividing cells were pressed from the anther before fixing and embedding. The writer would consider, then, that the ma- terial worked upon, Gasteria, tends to demon- strate a very great precision in the chromo- mere constitution of the meiotic chromosomes. It is hoped that it will be possible soon to make a.full report giving the evidence for the views here expressed. P Wm.

Like the evolution and development of so- ciety, the development of the individual is rapidly coming under more and more conscious- ly and systematically directed control; jwitness the gigantic educational machinery which is the product of the last twenty years. It is, perhaps, safe to say that the systematic direc- tion of the development of the individual is inversely proportional to his initiative, natural gifts and creative power. Morons are cared for; delinquent students are sorted and served each according to his individual need; the average student follows a routine. But what about the intellectually gifted student? Or- dinarily he is held in leash. Let me enter a plea for the emancipation of the gifted stu- dent, giving him a realization of his powers and responsibilities, the freedom to soar un- hampered above the levels of mediocrity, and to live at his highest level of achievement, weaving early his bonds of friendship with scholars. Instead of whipping him into line, let us whip him out of line. One of the great contributions from-modern psychology is the discovery of the individual and the projection of his profile, here and there in quantitative terms, bringing to us the reali- zation that in a given specific mental capacity one individual may have two, five, ten, twenty- five or a hundredfold the capacity of another with whom he is tied up in the educational mold. Our curriculum and our campus sanctions are so effectively set that very often these indi- vidual differences are successfully covered up or smoothed out so that the gifted individual as such is lost to himself as well as to society. A few years ago, particularly during the 1 Read before the Association of American Uni- versities at Baltimore, Maryland, November 9-11, 1922. 642 war, some of us were interested in finding from the senior class in college those who would give the greatest promise of achievement in research work. The rating blank? I have placed in your hands was used effectively for the locating of a certain per cent. of these. Personally I can testify that the individual interviews with those selected on the basis of these ratings furnished one of the most delight- ful and profitable opportunities for personnel work in administration. With the charts before the student and the interviewer, it was possible to enter into the life plans of the individual at a erucial stage in his career and cause him to view the situation in a critical attitude with profound interest. This is a procedure which has amply justified itself. But we soon found that the senior year is too late. At the end of the senior year the student has already chosen his career and, sad to say, often un- wisely, being guided largely by temporary emoluments, a shortsighted estimate of what is worth while, or the easiest outlet for activity at his then recognized level. Business, the in- SCIENCE [Vou. LVI, No. 1458 dustries, special interests, and the older pro- fessions have plucked from the senior class those who are most promising. Without strong traditions in their favor and without the prom- ise of financial rewards, science and art, with very few exceptions, trusting to luck, get what is left. It has therefore become clear that some selection, to be effective, should be made earlier than in the senior year, first, to give scholarship an opportunity in the competition for talent, and, second, to find the gifted stu- dent early enough to give him the advantages of preparation that he may crave and deserve. For this reason, some of us fall back on the opportunity of using the so-called intelligence tests and various substitutes for these at college entrance. These tests should be as much for the purpose of discovering the gifted student as for the purpose of culling out at the lower end. If I may mention a practice which has gradually found its way into Iowa, I may say that those who rank in the highest 10 per cent. at college entrance are summoned by the Dean of the College of Liberal Arts and told 2ANALYZED RATING OF FITNESS FOR GRADUATE STUDY Directions: Record your judgment on each capacity by placing a check mark (Vy) at the appro- priate point in the dotted line. Grade conservatively, bearing in mind that in the long run, for a class, there should be as many marks below average as above. If in serious doubt, put a question mark above the check. Guard rigorously against giving information (to, or receiving from, others who are rating independently, but otherwise consult freely with those who know the student well. At the bottom, cite (1) notable specific evidences of achievements, distinctions, opinions or other data that may throw light on the character of, ability or fitness for some particular field, if you know of any; and (2) mention marked negative traits which might be an obstacle in a learned career.

ZEAL FOR INVESTIGATION: deep in- terest in and craving for original and creative work DECEMBER 8, 1922 that the institution recognizes individual dif- ferences both in regard to quantity and quali- ty; that those having given evidence of un- usually high powers will be expected to show unusually high achievement through the col- lege course; that they will be watched with hopeful interest by members of the faculty; that an effort will be made to give them such personal direction and stimulation as they may need; and that eminent leadership is charac- terized by modesty and service. At the beginning of ithe second year, the Dean of the Graduate College summons them. Hach one is asked to bring three ratings on the blank you have seen; one by himself, one by a student friend, and one by an instructor. In the light of these analyzed ratings and the achievement of the freshman year, we talk over the situation with them individually in preparation for the selection of their major This usually leads to an early introduction to the most inspiring men in the major subjects which they are to elect. The selection of a major is then a distinctive step in the finding process, and the selection of an adviser ceases to be a mere form or a mere tool of administration. This procedure has served also to give mem- bers of the faculty, who are interested in re- search, a fresh interest and a clear point of view in the effort to discover im their classes other persons who show evidence of talent for research; because the gifted students do not necessarily fall in the highest group in mental tests. But even this approach in the freshman and sophomore years has revealed to us the ad- vantage of beginning still earlier. As was shown by Book in the Indiana survey, dull stu- dents are as likely to go to college as bright students. In ithe interest of scholarship it would be extremely wholesome if those who are interested in college entrance could reach down into the high school and inject into that atmos- phere the sentiment that the more gifted a student is in the secondary school work, the more desirable it is that he should go to col- lege. It is only by the cultivation of a personal at the beginning of their junior year. SCIENCE 643 sentiment of this kind that we can draw into the college those high school students of su- perior attainment whose education is now cur- tailed. What I have attempted to say so far is that it is in the interest of creative scholarship as well as culture in general that we should frank- ly recognize the enormous magnitude of dif- ferences in the individual capacity for achieve- ment. and that this principle should be asserted early in the course; first, that students may be found in the adolescent period of enthusiasm and generous aspiration and wisely protected from the machinery which is set automatically to grind high and low to a common grade; and, second, that instincts of curiosity, criticism, collecting and comradeship which blossom in the early adolescent period may be fostered in an atmosphere of freedom, encouragement and opportunity for achievement. Having thus entered upon a program of do- ing what we can to discover the gifted student, what can we do to follow up this discovery in the undergraduate course? This question has been answered by a very elaborate report pre- pared for the Association of American Uni- versity Professors by Professor Wilkins point- ing out sixty-seven varieties of things that may work to this end. I shall not here attempt even to summarize or classify these as they will undoubtedly appear in a formal report of his committee. The Division of Educational Relations, with Dr. Vernon Kellogg as chairman, in the Na- tional Research Council, has made a special project of this problem of the gifted student. It has various committees at work and aims to collect and disseminate information on this subject. I desire to acknowledge my obligation to this Division for inspiration and facilities in the work, but the suggestions I am now about to make are not official; they are purely personal convictions gained in my own experi- ence and observation. In the proposals I am about to make, I shall scrupulously avoid the recommending of any procedure which shall in the slightest detract from the present actual privileges and oppor- 644 tunities that the non-gifted student enjoys. In- deed, the whole appeal for the recognition of the individual in education is as much for the good of the non-gifted as for the gifted stu- dent. I am speaking here from the point of view of the intellectually gifted; but we all know that these have many weaknesses and that there are many other gifts or talents which ‘supplement intellect and in many imstances outweigh it. I shall therefore not tolerate any odious comparisons in terms of superior and inferior, and my appeal for the gifted shall not convey the slightest slur or disparagement of the non-gifted; but the fact is that, in edu- cation as in charity, there has been a constant tendency to give the first and most ardent care to the comparatively helpless. To this I would add some thoughtful equalization of interest. The discovery of the individual and the study of his talents in modern psychology has brought forth a maxim which may well be our educational slogan: “Keep each student busy at his highest level of achievement in or- der that he may be successful, happy and good.” This maxim is so pithy and cogent that we _ ean afford ito read it and reread it, accenting in turn each individual word, as every word of it stands for a principle. Thus, we may emphasize im reading, each, his, highest, achievement, successful, happy and good. Keep the moron busy at his highest level of achievement and he will be happy, useful and good; institutions have demonstrated that fact. Keep the gifted student in musie or art busy at this highest level of achievement and he may become an artist; that has been demonstrated. But science is slow in applying science to its own procedures. The challenge of educational psychology to-day is this: “Keep the gifted student busy at his highest level of achievement and you may find him a delightful comrade, a contributor to the world’s store of knowledge, and a vastly greater man than he could ever have been but for your thoughtful considera- tion.” : To act on the application of this principle, I would urge the extension of the following pro- cedures which have all been tried to some ex- SCIENCE [Vou. LVI, No. 1458 tent in various institutions but need to be pro- moted. 1. Sectioning classes on the basis of ability. We may say in very rough, and conservative terms that, if we think of a hundred college freshmen, chosen at random, and match the ex- tremes against each other, 5 at one end can do more than 5 times as much as 5 at the other end. The next 5 at one end can do more than 4 times as much as the next 5 at the other end. The next 6 at one end can do more than 3 times as much as the next 6 at the other end. The next 9 at one end can do more than 2 times as much as the next 9 at the other end. This accounts for the highest and lowest quartiles. The differences at the extreme are much larger than here represented because one or two at the upper end may be capable of rendering more than ten times the average output for the class, while the one or two at the other extremes are quite certain to fail. If, then, we seek for a practical basis for the sectioning of classes, we shall do well to recognize three levels which we may call the high, the middle, and the low, the middle being as large as the other two together. All too often our educational system is based upon the assumption that, where the great Creator failed to make all human beings equal, it is the business of the school to make them equal. To justify this procedure, the school men have found cover in the argument that this task works toward a democratic ideal; that it represents the rights of individuals; that it is necessary for the successful operation of edu- eational machinery; that it is good for the lowly individual; that the procedure is justified by results. Each of these defenses represents a fundamental error and misconception of fact in educational procedure. The democratic ideal in education, as every- where else in life, is not identical opportunity for all, but equal opportunity in proportion to capacity. The genius and the moron do not have quantitatively the same rights to knowl- edge; they have equal rights in proportion to their relevant capacities (quantitative and qualitative), and one should be as insistent upon his rights as the other. Among the advantages of such sectioning we DrcEeMBER 8, 1922] may note the following: it becomes possible to apply in teaching the pedagogical maxim, “Keep each student at his highest level of achievement.” This will result in the setting up of fair standards for quantity, quality, con- tent, and method of work adapted to a fairly . homogeneous group. This in turn will estab- lish a fair basis for praise and blame. The introduction of fair standards of achievement creates morale in a class. There will therefore be a larger output at all three levels; for such grouping is as advantageous to the untalented student as to the talented. Such progressive segregation is one of the best means of dis- covering and motivating the gifted student; be- cause he is thrown into vital and effective com- petition, works at his highest level of achieve- ment, and enjoys freedom for initiative in self- expression, and these associations are likely to awaken in him desire for progress, a sense of joy in achievement, and a feeling of fellowship. The introduction of this method, if properly managed, will not imerease the cost of instruc- tion, but may reduce it. I have pointed out in two articles on this topic? that there is no insuperable difficulty in the way of conflict of hours and cooperation of staff and that every institution that has given the method a fair trial is continuing it. 2. Honor courses. Let each department in which there are progressive teachers set out one or more courses to which admission may be gained only upon evidence of fitness. The principal factor to take into account should be high scholarship, or creative achievement, or both together with health. The standard for passing should be much higher than in an or- dinary course. The class may well be socialized and the work so arranged as to challenge the in- dividual to wide reading, verification and de- fense of his findings, experiment, independent thinking and self-expression. Under no cir- cumstances should the course be limited to lee- 2I am, of course, speaking of the larger in- stitutions; indeed, the very necessity for differ- entiating students may prove to be a decided dis- advantage to the small college. 3In School and Society. SCIENCE 645 ture or textbook; nor should formal essays or papers be read by the student. It should not furnish an opportunity for the instructor to recite the findings of his researches, although the subject of study will most profitably le within or around his field of research. Admission to these courses should be in the hands of a scholarship committee to which re- commendation for admission and reports of achievement should be made by teachers. As- suming as a unit of credit three year hours; i.e., six semester hours, the exceptional student might ‘be permitted to take one course in the sophomore year, two in the junior year and three in the senior year, but not more than one course of this kind each year in a given de- partment. Thus the amount of credit in such courses might furnish a better basis for de- signing honor students for graduation than the present basis of mere credits courses. in ordinary The existence of such courses would act as a stimulus to the gifted student who might otherwise be disposed to loaf. Dozens of varieties of honor courses are being tried in different institutions. This plan thas the ad- vantage of flexibility, simplicity of administra- tion and a salable proposition to the student. 3. Individual work. Shall the freshman who has read current literature and history extensively and lives in it be forced to ruminate the cud of predigested pellets which form the diet of freshman general history? Shall the gifted student, who, given the freedom of the library, can read up in one half to one fifth the time what is doped out in lectures on special topies, be forced to acquire a specialized knowl- edge-in that specific form and at that set pace? Shall the student who, if given free hands, could pass all college examinations required in a year or two be required to mark time for four years? Or, granted that it is good for him ito be in college for four years, shall his horizon be limited to the scope of course units? Shall the gifted student who can learn the two hour assignments in science or history or lan- guage in fifteen minutes be encouraged to loaf or play the rest of the time? Or shall he be given a different assignment? Shall the gifted student who can do independent work in li- 646 brary, laboratory, field, or creative work have his progress restricted by course units? Such questions are all the more pertinent here to-day because American institutions have answered them in a different way from that in which they have been answered by the older in- stitutions in Europe. The American college coddles the student; laces him into a strait- jacket of forms, and spanks or rewards him somewhat in proportion to his conformity to this corset. Professors talk about academic freedom. Perhaps it is time that we heard from the student about academic freedom. One wholesome practice is to excuse stu- dents from too elementary courses and give them more advanced work. But in many eases there should be another outlet. Students who, on admission or later, give evidence of high capacity for achievement should, on recommen- dation to the department and approval by the scholarship committee, be permitted to register for individual work as a substitute for required courses, work to be counted for credit as in the course. But ithe standard of passing should be much higher than for the class work (1) to prevent rush to this privilege, (2) to call for high achievement on the part of a gifted stu- dent, and (3) to allow for the effect of cram- The test should, however, be more plas- tie and personal than the formal tests on course ming. content. In addition to scholarship, admission to such registration should be based upon evi- dence of fitness for such independent work. The principle of this type of registration once approved by the faculty, ‘the administration of it should be left largely to the departments, so as to make it simple and flexible. Departments might find it possible to have syllabi, bibliographies and study hints avail- able as an invitation to individual work. Oc- casional interviews should be granted, but not for the purpose of telling or teaching. In certain subjects each individual’s work might be so motivated and organized as to carry a considerable number of students in this way rather than in elass, and thereby lighten the Departments might also go so far as to recognize voluntary groups of burden of teaching. two or more students for cooperative study in SCIENCE [Vou. LVI, No. 1458 preparation for such tests as the department might set. In every case, the student would have the advantage of working at the highest level of achievement, would be free from ithe lock-step of the class room, free from the bur- den of being bombarded with matters which he already knows. Mathematics, history, gov- ernment and psychology would be good ex- amples of subjects to pursue in this manner. Mathematics is peculiarly a personal affair; it is a skill which the teacher can not impart. In foreign language there is no reason why a gifted student should spend two years in the class room in learning to read French and Ger- man; ‘but if he is given time and realizes what it is for, he can read French or German litera- ture and science and live in it and use it to best advantage and thereby lay a better founda- tion than he could by merely taking a course. Even laboratory courses might well be mastered in this way. Only gifted students ean profit ‘by this privilege. Inferior, mediocre or aver- age students need to be nursed and coddled by the methods we now employ for all. The privilege is merely an honest recognition of the fact that there are some who can learn for themselves, without tutor, lecturer or class whip. 4. Early contact with mature teachers. Re- cently, a faculty committee in a auniversity brought in a report representing essentially this: (1) that elementary students should be taught in sections not to exceed twenty-five; (2) that elementary students should be taught by the mature men in the department; (3) that the teaching schedule for these men should be reduced in order that they may have itime for research; and (4) that salaries should be raised. One member of that committee, representing a very large department, was asked to prepare a budget for his department embodying these recommendations. Nothing more has been It simply can’t be done. With the present influx of students, there is a tendency to reserve the most inspiring men for the most advanced courses and leave lower courses in the hands of cheap labor. This is especially demoralizing to ithe gifted student. When a department has from two to fifty sec- heard of the report. DECEMBER 8, 1922 tions in the elementary subject it can afford to so organize the course ithat the academically mature and successful man is made responsible for the content and method and meets every student in that course at least once a week. This will probably of necessiity involve the com- bination of the meeting of the class in large di- visions for lectures, demonstrations, or formal exercises under mature men and personal work with the students in small sections under younger men. Let me hasten to say that this must not be confounded wiith the old-fashioned lecture plan with quiz sections; that plan is dead, or should be. But that should not condemn the meeting of ‘the class part of the ‘time in large divisions and part of the time in small sections. Har- vard was one of tthe worst sinners under the old lecture and quiz systems. But to-day Har- vard is in some departments setting a model for this type of organization which imsures in- spiration and thoroughness in the work. The sophomore in economics, e.g., may work under such men as Taussig, Carver, Burbank, Ripley and Day in a single course and carries away something which stays by him (through hfe. The professor in charge of the course himself carries one section made up of Ithe most gifted students. The plan I commend on the basis of my own experience is to recognize three needs of in- struction: (1) inspiration, motivation, and or- ganization of the work; (2) systematic read- ing, practical exercises, or experiments; (3) self-expression. The first can be achieved in divisions of from one to five hundred by ca- pable men; ithe third must be done in small sections; and the second may be directed either from ‘the large division or the small section. The first can be done only by a relatively ma- ture teacher who has marked ‘ability in leader- ship and the power of address. The third may be done by well-selected, young teachers; the second should represent the ingenuity of ‘the mature teacher and the capacity for routine and detail of the young man. The organization and conduct of the large division work may be in \the hands of one man. But where there are distinct divisions in a de- SCIENCE 647 partment, as in economics, sociology, botany, or psychology, the first year course should be a cooperative affair. There is no need or justi- fication for electives ttioward a first year course in a department. There should be only one economics 1, one American history 1, one botany 1; for the majority of students take only one course in the depaytment and a course of the second level may well be built upon the general ‘orientation gained in a general survey course. The finest and most exitreme embodi- _ment of this principle is perhaps the course in ontemporary civilization—a five-hour course required of freshmen in Columbia Uni- versity.+ 5. Time. that may be done for the gifted student. which can not be prescribed but may be included in the general faculty policy of liberality toward the few students who give unmistakable evi- dence of exceptional achievement. One of these factors is time. 6 In diseussing the gifted student problem, a professor who spoke with a German brogue said, “Vot do ve professors vant? Ve vant Vot does the gifted student vant? He vanilts Itime.”’ And he was right. The gifted student wants time to pursue his ideal; and he can best get that by some generous policy of exemption from formal training. This comes hard. I well remember what precious hours our faculty wasted in trying to keep Mr. Steffanson, the now famous explorer, from sub- mitting the evidence showing that he could acquire on short notice those units of learning which we have so logically prescribed in our four year course, all of which he could have There are a number of things time. met in a year or two while he was doing some creative work on the side. (As a matter of fact he did get permission to do that very thing and succeeded. ). This sounds like iconoclasm. dean and the registrar and tthe professor. As a practical administrator I am not calling for any great or sudden revolutionary procedure; 4The October number of the Bulletin of the Association of American University Professors contains valuable material on ‘‘Initiatory Courses for Freshmen.’’ It disturbs the 648 but I should like to enter a plea for the recogni- tion of opportunity for reasonable treatment of the gifted student commensurate with his exceptional powers; and one of the conditions for achievement is leisure and the privilege of working at your own pace. To the now itraditional practice of allowing excess registration in proportion to quality of eredit should be added the proviso that an ex- cess schedule must include an honor course each year, and general health and social orien- tation should be taken into account. is done, the student may combine the saving of time with the winning of distinection—a type of distinction which has real value. A flexible seale of excess registration may then safely have such range that the very gifted student could complete the college course in three years if he so desired. Comradeship. The first and greatest need of the gifted student is comradeship or fellow- ship in the late adolescent pursuit of his ideal if it be the search for truth. Each of us who has had any.degree of success in original work can look back to little incidents where a teacher or a more advanced fellow student conveyed the sentiment; you are good enough to be in my company; see with me this vision; share with me ithis harvest; let us seek truth first hand; I want you ‘to fall in love with my problem; over the mountain top there is hight. This can not be achieved through any formal academic procedure. Probably less than one fourth of the college iteachers in the United States are capable of participating im this privilege, and yet the principle needs to be urged upon the academic community in order that ‘those who have this interest at heart may not trust the machinery to do what it can not do; may not underestimate the great significance of little things in this direction, or may not in the in- terest of modesty or academic courtesy hesi- tate to exercise this privilege.

In- vitation to the home; participation in small groups, clubs, and societies; the enjoyment of special laboratory and library privileges; the exemption from hampering formalities; the en- couragement of rewards of all kinds; ithe stimu-: lation of competition; the organization of rigorous academic wrangling and criticism; the participation in the reading of manuscripts,. ‘the conduct of experiments, scientific expedi- tions, and learned societies. These things are all of very great value to the student who has been taken ito comradeship for research as a neophyte. They come to him because he has been admitted to comradeship and in return he gives his best. He needs counsel to curb his enthusiasms, to acquire fundamental habits and knowledge, to lay good foundations through training in the fundamentals, to fit himself into the social body in which he lives, to care for his health and manners, to seek reasonable outlet for his in- genuity, to keep from being a hermit or a prig, to keep in the humble attitude of a master who is not puffed up over his achievement. C. HE. SEASHORE Stave UNIVERSITY oF Iowa WHAT SHALL BE TAUGHT IN THE FIRST YEAR OF COLLEGE CHEMISTRY?! THERE is much uncertainty among college chemists as to the proper treatment of fresh- men, some of whom had chemistry in high school, while some did not. With a class not exceeding one hundred and a somewhat limited teaching staff, there is no better method than to put them all in the same class with the same text. No apology need be offered for such a procedure. In such small classes the teacher can keep in close touch with the individual student and vary the program ‘to suit individual possibilities. This is especially easy in the laboratory drill where the experiments may be 1 Paper presented at the Pittsburgh meeting of the American Chemical Society. DECEMBER 8, 1922] selected to fit the student’s preparation and ability. In larger institutions, it is more satisfactory to group those with no previous training in a separate class. It is to be hoped they had high school physics as a seientifie foundation. Gen- eral chemistry for such a class should be just what the name implies—a general treatment including traditional descriptive chemistry, physical, industrial, organic, analytical and something of the historical development. Above all, even above the accumulation of facts, ‘this course should give training in real scien- tifie thinking. This seems like a large undertaking, but it merely means that we take the student up on a high mountain and show him the promised land. The fact that the majority of ‘this class will never study any more chemistry is added rea- son for a proper breadth of treatment. The problem is more difficult for students who may possibly feel satisfied with their knowledge of high school chemistry. They enter college to be stimulated and it is fatal to let them feel that college general chemistry has but little in the way of novelty for them. Hence I counsel against a mere hasty review for one semester by way of itransition to some advanced course. Such “rush” courses deadly, dull and unsatisfactory to teacher and pupil. Nothing short of a full year of rather stiff general chemistry will serve the needs of this class and it can be ttaught with all the are freshness - appetites. The high school course was good discipline. It furnished information inspired the student with a liking for chem- needed to whet jaded intellectual much useful and istry. It is no reflection on high school teach- ing to insist that under no circumstances shall a year of chemistry be omitted. The explanation is found in the immaturity of the student, the high school en- -vironment and the lack of time given to the course. college general The college course must cover again the same ground—and much more. It need not, how- ever, be a dull rehash. The broader general chemistry in college must present more funda- SCIENCE mental views. 649 Much more of physical chem- istry, more exact quantitative experiments, and a glimpse of the newer developments such as radioactivity, atomic structure and colloids are a proper part of such a course. A very simple but reasonably complete system of qualitative analysis may well ‘be used as the laboratory drill during the second semester. This teaches system, classification and comparison. The stu- dent greatly enjoys his quest of the unknown and sees a definite.use for a somewhat con- fusing array of facts he may have accumu- lated. That majority who never take ad- vanced chemistry have a right to the joys and benefits of qualitative analysis. During this difficult freshman year the old facts of high school chemistry must be dealt with in an interpretative spirit. When taken behind the scenes, so to’ speak, the student sees a new meaning in the subject. There is small . doubt that unless all ithat has gone before, more or less loosely held in mind, is worked over into a solid foundation ‘the student is chemically crippled for life. A certain amount of forceful repetition is ‘the essence of good teaching. Hven in the second, third and fourth years, we all find it profitable ito repeat and expand what was presented in the freshman year of general chemistry. This makes the thorough chemist. It may be well to mention a number of spe- cific topics to be stressed for the class. The historical development of the system of molecular and atomic weights is far more con- vineing to ‘the student than a mere statement of the system as it now is. In fact a little of the historical introduction to many _ topies interests the class and develops the research attitude of mind. It may seem absolutely ridiculous to talk of research on the part of a freshman, yet clever questioning as the steps of a historical piece of research are discussed will do much in stimulating the student into a research attitude of mind. Structural formulas appal the class on first sight. Later familiarity breeds, not contempt, but appreciation. The confusion of formulas of. mitrogen, arsenic, antimony and usual phosphorus compounds is easily cleared up by 650 constant use of structural formulas. With such practise the study of two chapters of organic chemistry is not appalling. A library shelf, easily accessible and espe- cially selected for students of general chemis- try, pays goods dividends. Other texts, books on the applications and special advertising pamphlets should fill this shelf. Not all will read but those who do are the ones who take advanced chemistry. Stress must be placed on equilibrium, early and late, on solutions, on that fascinating chapter about the periodic system, on the hydrocarbons and their derivations and such other topics as appeal strongly ‘to ‘the teacher. * * *% * * = An informal talk with each student or a written test on entrance will indicate ‘that some who have had high school chemistry will do better in the class with those who had none. Since high schools vary widely in quality of” instruction in chemistry (as do colleges also) the mere name of preparatory chemistry should not be accepted without some investi- gation. Usually the record of the school is sufficient evidence. Harry N. Houmes OBERLIN COLLEGE, OBERLIN, OHIO ON THE EXISTENCE OF A HITHERTO UNRECOGNIZED DIETARY FAC- TOR ESSENTIAL FOR RE- PRODUCTION!

We have employed a ration of casei (18), cornstarch (54) and lard (15) to which putterfat (9) and salts (4) are added, ithe ani- mals receiving separately and daily .4 gram each of dried whole yeast. Such animals are sterile. They are chiefly so in the first generation and wholly so in the next succeeding one. The sterility of dietary origin yields a highly characteristic picture. Animals suffering from it do not differ so pro-- foundly from normal ones in their ovarian: funetion as they do in placental behavior. Ap- proximately the same number of Graafian fol- licles mature and rupture per ovulation and! the ova are fertilized and implanted. The placente are abnormal. They may persist al-. most throughout gestation but show as early as the second day of their establishment begin- ning blood extravasations which increase in ex- tent. Resorption invariably overtakes the pro- ducts of conception. Natural foodstuffs contain a substance, X,. which prevents such a sterility or which cures- the disorder occasioned by the purified dietary regime. We have thus been able to witness a comparatively sudden restoration of fertility ‘to animals of proven sterility, and whose con- trols continued sterile, by the administration: of fresh green leaves of lettuce. Even ithe dried leaves of alfalfa appear to possess a similar potency. The proven efficacy of leaves invites inquiry into ‘the certainty of segregation of the new dietary factor from vitamines A and C. As regards A, at is conceivable that amounts of A adequate for normal growth, freedom ~ from eye disease and, indeed, vigorous health. might sill be inadequate for the reproductive: function. Such a coneeption is apparently strengthened by the reappearance of fertility which we have discovered to take place when the butierfat quota in the above diet is in- creased so as to constitute 24 per cent. by weight.? A sufficient answer to this conception,. however, is afforded by our demonstration that in some dietaries reproduction may be un- hindered when the A content is lower than in 2 Drummond (Biochem.

Such a diet is furnished by rolled oats (40), gelatin (10), casein (5), dextrin (40.3), butiterfat (1), and salts (3.7) (MeCol- lum). It is perhaps also pertinent to point ‘out that we have detected an invariable sign of inadequacy in (the A factor of greater delicacy than ‘those hitherto employed and may thus recognize such inadequacy long before growth impairment, for instance. The sign is con- stituted by a highly characteristic aberration of the estrous eycle. And we have been able to demonstrate tthe persistence of fertility with a wheat-milk ration (Sherman) even in the absence of butterfat and when ithe A deficiency is heralded by the continuous exhibition of the new sign. The beneficial effect of a very high percentage of butterfat> consequently, seems preferably explained ‘by its possession of a, definite though low quota of the fertility con- ferring substance. Furthermore, a sample of cod liver oil tested by us and proven to possess a much superior A content to butterfat is far less efficacious than butter in curing or pre- venting the impairment of the reproductive function. The beneficial dietary factor can not be iden- tical with the antiscorbutic vitamine C, fior curative effects have been secured when ground whole wheat was added ito our purified ration, and the cereals are, of course, notably deficientt in C. Moreover, although some favorable in- fluence on growth thas been noted, at thas been impossible for us to secure with orange juice the fertility effects so evident with lettuce. Lastly, we may refer to the suggestions either implied or expressed in the publications of some investigators (Osborne and Mendel, Kennedy and Palmer) that yeast contains some - toxic substance inimical to the organs of gen- eration and hence causing sterility or that it simply does not contain enough of the water soluble vitamine B. The curative foods could hardly be assumed to. detoxify. Nor do we believe our animals suffered from lack of B, for growth was excellent; and as much as 25 per cent. by weight of yeast (which must have given a great surplus of B) did not change the result. Fertility, when wheat germ is used as a source for B, results not from more B but be- cause wheat germ is also rich in X.

Willson to know that the last months of his. life were actively occupied in the successful solution of certain scientific problems. Professor Willson died at his home in Cam- bridge, November 1, 1922, in the seventieth year of his age. He was a graduate of Har- vard College in the class of 1873, and took his Ph.D. at Wiirzburg a few years later, after specializing in physics, a subject which, in con- junction with his astronomical experience, gave- just the right equipment for his solution of aerial navigation problems at ‘a much later- dalte. The main facts of his professional career are available in the biographical reference books, while others can speak more fully than I of his devotion to the building up of a depart-- ment of astronomy in Harvard College. Fol- lowing his retirement as professor emeritus in 1919, he devoted an increasing amount of time to his own work in Cambridge along the line of air navigation instruments, and this later work is not perhaps so well known. His development of ithe air-craft sextant was a notable achievement successfully demon- strated during the war, and widely adopted Anti-aircraft trans-Atlantic flight, and ground speed indicators were only since. defense, a few of the subjects which claimed his keen- est attention and in which definite progress. had been made.

NOVEMBER 6, 1922 SCIENTIFIC EVENTS MORTALITY FROM CANCER THE Department of Commerce announces that the returns compiled by the Bureau of the Census show that over 76,000 deaths were due to cancer in the death registration area of the United States in 1921, and assuming that the rest of the United States had as many deaths from this cause in proportion to the population, the total number of deaths from cancer in the entire United States for 1921 was 93,000, while for 1920 the number is estimated as 89,000 or 4,000 less than for 1921. The trend of the cancer death rate is upward, the rate for 1921 being higher than that for any earlier year in twenty-three of the thirty- four states. The cancer death rate in the regis- tration area in 1921 was 86 per 100,000 popu- lation, against 83.4 for 1920. In comparing the death rate from cancer in one state with that in another, the bureau uses “adjusted” rates in order ito make allowance for differ- ences in the age and the sex distribution of the population, because, generally speaking, only persons in middle life and old age have cancer, so that a state with many old persons may be expected to have more deaths from cancer than a state with comparatively few old persons. The highest “adjusted” cancer rate for 1921 is 99.6 per 100,000 population for the state of Massachusetts, and the lowest is 47.6 for the state of South Carolina. For a few states ad- justed rates have been calculated separately for the white and colored population. In this group of states the highest adjusted cancer rate for the white population is 95.9 per SCIENCE [Vou. LVI, No. 1458 100,000 population for New York and the highest rate for the colored population is 90.6, also for New York. The lowest adjusted can- cer rate for the white population is 51.5 for Tennessee and the lowest for the colored popu- lation is 36.4 for Florida. The adjusted rates show that the northern states have comparatively high and the south- ern states comparatively low cancer mortality, while there is little difference between the ad- justed cancer rates of the white and colored races of the same states. COLORS FOR TRAFFIC SIGNALS THIRTY-NINE men, representing as many ad- ministrative bodies, trade associations, scien- tifie or technical societies, and government de- partments, make up the sectional committee on colors for traffic signals which was organzed at ‘a meeting in New York City on November 9 under ‘the auspices of the American Engineer- ing Standards Committee. In opening the meeting, P. G. Agnew, secretary of the Amer- ican Engineering Standards Committee, said that this was unquestionably the most repre- sentative group that has ever come together anywhere in the world to discuss this subject. The committee elected as its officers the fol- lowing representatives of the three sponsors for the code: Chairman, Charles J. Bennett, state highway commissioner of Connecticut, representing the American Association of State Highway Officials; vice-chairman, Dr. M. G. Lloyd, representing the United States Bureau of Standards; secretary, Walter S. Paine, research engineer, Atna Insurance Com- pany, Hartford, Conn., representing the Na- tional Safety Council. Because of the difficulty of ‘bringing the en- tire sectional committee together at frequent intervals an executive committee was appointed with instructions to collect information on the subjects coming within the scope of the code, to digest this information, to appoint sub- committees, to arrange for the necessary re- search work, and to draft definite reeommenda- tions for the consideration of the sectional The executive committee consists of the following: committee.

The sectional committee by resolution invited the Aeronautical Chamber of Commerce of the United States to participate in the work of the committee. at the organization meeting of the sectional committee to appoint a sub-committee to investigate the efficiency of all color signals now in use as traffic signals, and where possible to ascertain the reasons for adopting certain colors for specific uses. This committee will investigate the use of various types of semaphores and silent policemen. Another committee will make an original study of specific colors for definite uses as a check upon previous researches and to establish certain colors for traffic signals. A third committee will study non-luminous signs and signals and propose, after thorough research, signs of definite colors and shapes for highways and also for railroad crossings. It was also decided THE CHARLES A. COFFIN FOUNDATION On May 16, 1922, Mr. Charles A. Coffin, in his seventy-eighth year, retired from the active leadership of the General Electric Company. Mr. Coffin has been identified with the develop- ment of the electrical industry since 1882. He was the founder and creator of the General SCIENCE -mittee appointed by the board. 653 Electric Company, of which he has been the inspiration and leader for thirty years. As an expression of appreciation of Mr. Coffin’s great work not only for the General Electric Company but also for the entire electrical industry and with the desire to make this ap- preciation enduring and constructive as Mr. Coffin’s life and work have been, the board of directors of the General Electric Company created on ‘his retirement and now desire to announce the “Charles A. Coffin Foundation.” A fund of $400,000, to be known as the “Charles A. Coffin Foundation,” has {been set aside and the income, amounting to approxi- mately $20,000 per year, will be available for encouraging and rewarding service in the elec- trical field by giving prizes to its employees, recognition to lighting, power and railway companies for improvement in service to the public and fellowships to graduate students and funds for research work at technical schools and colleges. The foundation will be con- trolled and administered by a foundation com- This ¢om- mittee, within the limits of ithe purposes for which the foundation is created, will have power to change the conditions applicable to “the distribution of the fund and the amounts for each particular purpose. The committee proposes to distribute the in- come of the foundation as follows: First. Eleven thousand dollars ($11,000) in prizes for the most signal contributions by. em- _ployees of the General Electrie Company toward the increase of its efficiency or progress in the electrical art. Particularly, the prizes are to further encourage suggestions from workmen. With each prize, the company will give a cer- tificate of award. Second. A gold medal, to be known as the “*Charles A. Coffin Medal,’’ will be awarded an- nually to the public utility operating company within the United States which, during the year, has made the greatest contribution towards increasing the advantages of the use of electric light and power for the convenience and well- being of the public and the benefit of the indus- try. The company receiving the medal will also receive one thousand ($1,000) for its employees’ benefit or similar fund. 654 Third. A gold medal, to be known as the *“Charles A.

The company receiving the medal will also receive one thousand dollars ($1,000) for its employees’ benefit or similar fund. Fourth. Five thousand dollars ($5,000) is to be awarded annually for fellowships to graduates of American colleges and technical schools who, by the character of their work, and on the recom- mendation of the faculty of the institution where they have studied, could with advantage continue their research work either here or abroad; or some portion or all of the fund May be used to further the research work at any of the colleges _ or technical schools in the United States. The fields in which these fellowships and funds for research work are to be awarded are: Electricity; physics; physical chemistry. A committee appointed by the foundation com- mittee will award such fellowships and funds for research work, with the advice and cooperation of a committee of three, one to be appointed by each of the following: The National Academy of Sciences, Institute of Electrical Engineers and the Society for the Promotion of Engineering Education.

In its issue of October 28 Nature says: “In an article on Lord Incheape’s task in the Swn- day Times of October 22, member of the government of India, Lord Meston, makes an alarming suggestion. Speak- ing of things ‘useful, but not essential,’ he says, “many of the. research institutes amd the like will come under ‘the shears.’ The illiberal spirit which inspired our domestic wielders of the axe may thus be carried by one of them ito India—a country which, more ithan any other, perhaps, has benefited by the application of science to ‘useful’ purposes. The plant breed- ers there, alone, have literally added millions to the country’s wealth; new wheats and cot- tons yielding 20 to 30 per cent. more than the indigenous varieties have already been success- fully introduced. It must not be forgotten that, in India, ithe prosperity of agriculture is a fundamental element of the solvency of the government, for there, the state, as owner of the soil, takes one half of the rental value of the land. The sum thus raised approaches a moiety of the whole taxation of the country. It is to be hoped that such a suicidal policy as that indicated by Lord Meston will not be ad- vocated iby Lord Incheape, though as a quon- dam member of the Geddes ‘Committee he may be inclined to repeat its mistakes.” Dr. H.

Tue University of Paris has published com- parative statistics of students matriculated in 1921 and 1922, which are quoted in the Journal of the Medical Association. In July, 1921, the total matriculation reached 21,185 (17,993 men and 3,192 women). In 1922 the number had 21,612 (18,066 and 3,546 women), or an inerease of 427 students. The department most strongly represented in 1922 grown to men was law. Then came medicine, with 4,639 stu- dents (738 women); belles-lettres, with 3,381 students (1,450 women); seiences, with 3,179 students (532 women), and pharmacy, with 743 students (234 women). The department in which the most women are enrolled is that of belles-lettres (1,450 women as against 1,931 men). From 1921 to 1922 the number of 658 French students at the University of Paris increased by $59, while the number of for- eigners decreased by 332. THE annual report of the general progress of the British Museum and of the Natural His- tory Museum during 1921 has been issued. Notes by Sir F. G. Kenyon and Sir Sidney F. Harmer deseribe the additions made to the collections and the rearrangement of rooms. During the year 901,209 persons visited the British Museum, of whom 159,177 were read- ing room students. Visitors to the Natural History collections in Cromwell Road numbered 479,476. PRELIMINARY announcements by the Austra- lian Research Council indicate ‘the scope of the Pan-Pacifie Scientifie Congress to be held in Australia in August, 1923. The program calls for organized conferences on fundamental topics in anthropology, agriculture, botany, en- tomology, geography, geology, geodesy and zoology. Among the discussions in geology formulated by E. C. Andrews are “Relation of coral reefs to glaciation,’ “Structure of the Pacific,’ “Mountain building and igneous intrusion,” “Carboniferous and Permian strat- igraphy’ and ‘Mineral resources of the Pacific.” Arrangements are being made for excursions to the desert, to the tropical jungles and to living coral reefs. By request of ‘the Australian committee, headed by Sir T. Edg- worth David, the National Research Council, which organized the First Pan-Pacific Scientific Conference at Honolulu in 1920, is cooperating to insure a profitable meeting for 1923. ReEPoRTS from Commander J. C. Thompson and Hans G. Hornbostel, representing the Bishop Museum, indicate successful outcome of the explorations in Guam and in the southern Marianne Islands. Much information has been the culture of vanished Chamorros, a flourishing race, at the time of Magellan’s visit in 1521. Under the direction of M. F. Malcolm, assisted by the governor of Saipan, the remarkable ruins on the Japanese island of Tinian, visited by Anson (1749), Mortimer (1791) and Freyeinel (1817), are being studied with a view to enlarging the knowledge of migration routes and inter-rela- tions of Pacific peoples. obtained regarding SCIENCE [Vou. LVI, No. 1458 Harvarp University has come into posses- sion of ithe Farlow botanical library, one of the most valuable collections of books dealing with cryptogamic botany in the world, quarters having been provided for it which meet satis- factorily the conditions of gift contained in the will of Professor William G. Farlow, who died in 1919. Under Prorfessor Farlow’s will, this collection, comprising 11,000 volumes, was given to Harvard on condition that, within three years after the testator’s death, suitable arrangements should be made for placing it in fireproof quarters in proximity to the Farlow herbarium of cryptogamic plants, already owned by the university. These conditions have been met by ‘the decision of the Harvard Corporation to house both the Farlow library and the herbarium in the Divinity Library building. THE expedition sent last July by the Amer- ican Museum of Natural History ‘to the island of Santo Domingo to secure, if possible, speci- mens of the rhinoceros iguana and the giant tree frog, has returned to New York with a large collection, including over two hundred living specimens in addition to the preserved material. The expedition was financed by the Angelo Heilprin Fund and the materials which it collected will be installed in the museum’s new Hall of Reptiles, at present under con- struction. Under ithe leadership of Dr. and Mrs. G. Kingsley Noble, ‘both of the museum staff, the party crossed the entire length of the Dominican Republic while pursuing its in- vestigations. After exploring the Quita Espuela, an outlying mountain range in the northeastern part of the island, the expedition crossed to Constanza, in the heart of the cen- tral Cordillera. From there it pushed on to Barahona, and finally to Los Lajas on the Haitian border. Tue Sigma Xi Club of Southern California held its first regular meeting in Los Angeles on the evening of October 28. About eighty- SIX persons were present including members from numerous Southern California towns. Dr. W. L. Hardin, president of the club, pre- sided. Professors R. A. Millikan, C. G. Dar- ~ win and Paul Epstein, of the California Insti- tute of Technology, were guests of the elub and DECEMBER 8, 1922 were elected honorary members. Professor Millikan told of ithe activities of the scientific committee of the League of Nations, of which he is a member, and discussed what is desira- ble in international cooperation in scientific matters. Professor Darwin addressed the club on “The nucleus of the atom.’’ The following officers were elected for the ensuing year: President, W. L. Hardin, Mt. Washington, Los Angeles; vice-president, L. S. Weatherby, Uni- versity of Southern California; secretary, P. W. Merrill, Mt. Wilson Observatory; treasurer, EK. E. Chandler, Occidental College. Nature notes the assignment to science of the proceeds of the first performance of a great play by a leading dramatist. The play was the tragedy “Judith,” by M. Henri Bernstein, pro- duced at the Gymnase Théatre, Paris, on Octo- ber 12, before a brilliant and distinguished as- sembly, which comprised ministers of state and the chief social and intellectual leaders of the city. The receipts were for the benefit of the French Confederation of Scientific Societies, and amounted 'to about $5,000. M. Bernstein gave /his royalty as author, and Mme. Simone, who took the ititle part and is said to have ob- tained the greatest triumph of her career, de- voted her fee to the same purpose. WE learn from the Journal of the American Medical Association that the national alliance to promote an increase in population in France is planning a competitive contest with prize awards totaling 120,000 franes for the best essays setting forth the eritical demographic situation and the best means of combating the danger. The first prize is 50,000 franes; the second, 10,000 franes; the third, 8,000 frances, while the balance of the 120,000 franes will be distributed in small sums. The essay which is awarded the first prize will be printed by the national alliance and 500,000 copies will be distributed throughout the country. The com- petitors will deal more especially with the fol- lowing topics, but they will not be confined to these: (A) The evil as it exists: (1) the de- crease of the birth rate in France, during the past century; the inevitable further decrease in the future if the most energetic measures are not adopted, and (2) the dangers that lurk in SCIENCE 659 the fall of the birth rate and the catastrophe that threatens not only the life of the nation but also of the individual. (B) The proposea remedies: (1) the respect due to large families and the advantages that they deserve; (2) the reforms needed to raise the birth rate—at the price of financial sacrifices, if necessary; if by the expenditure of certain sums an increase in the number of births ean be brought about, no money could be better expended, and (3) in- struction in the matter of the moral, social and patriotic duty of paternity and maternity— their joys and their rewards. UNIVERSITY AND EDUCATIONAL NOTES Tue University of Pennsylvania will receive $200,000 for the establishment of a department of clinical surgery from ‘the estate of Edmund A. W. Hunter. The (bequest was made with the provision that the addition to the university be known tas “The Agnew and Hunter Depart- ment of Clinical Surgery,” in memory of Dr. D. Hayes Agnew and Dr. Charles D. Hunter. The latter was the son of the donor. A runp of $60,000 for establishing a chair at Tulane University of tropical -diseases and hygiene, and one amounting to $30,000 for constructing an isolation ‘building for the Charity Hospital will eventually be available to these institutions under the will of the late William G. Vincent. THe trustees of Hamilton College have authorized the erection of a lbiolegy-geology and museum building to cost approximately $225,000, and the construction of an addition to the chemistry building the estimated cost of which is $60,000. It may be noted further that the board of trustees, by unanimous vote, with twenty-five of the twenty-eight members of the board present, authorized the fixing of four hundred as the ultimate and maximum number of undergraduates in the college, and directed that all building plans take that num- ber into account as ithe total for which pro- vision should ‘be made. * RurH Oxey, Ph.D., has resigned from the biochemical laboratory of the University of 660 Towa Hospital, Iowa City, to take up the teaching of nutrition at the University of Cali- fornia.

Dr. Uichanco had been on leave for about three years, as a traveling fellow of the University of the Philippines in the United States, spend- ing the larger portion of this period in post- graduate work at the Bussey Institution of Harvard University. DISCUSSION AND CORRESPOND- ENCE WEATHERING UNDER CONSTANT CONDITIONS Durine the past summer the writer visited a number of the paleolithic caves of southern France and northern Spain, and there had an opportunity to study the effects of weathering upon rocks and upon the works of man where conditions have apparently remained un- changed during a time which is variously esti- mated at from 18,000 to 30,000 years. Every geologist from his own observations and reading can give many examples of rapid weathering, such as that on the western front of the Amiens Cathedral probably not an orig- inal stone placed there by the builders in the fifteenth century can be found; that the out- side stones of Westminster Abbey have been renewed five times over; that ithe stone of which the British Houses of Parliament are built has crumbled so rapidly that already it has been necessary to replace many of the stone orna- ments with cast iron. On the other hand, so many objects showing almost no evidence of weathering have been taken from tombs in Egypt where they were 1J. W. Gregory, ‘‘Geology of To-day,’’ page 31. SCIENCE [Vou. LVI, No. 1458 buried for many centuries that little surprise was evinced when the Metropolitan Museum Expedition of 1919-1920,? announced the dis- covery at Thebes, in the chamber of the tomb of a man of great wealth, of a large number of remarkably preserved small wooden models illustrating the daily life of his household: brewers maling beer, cooks making bread, boats with their boatmen, cattle fattening in their stable. These wooden models, which are “practically as perfect as the day they were made,” were carved and stored away about 4,000 years ago, but so little have they been affected by the agents of the weather that even the finger and thumb prints of the men who carried the figures up to the tomb are pre- served as well as fly specks on the models and spider-webs with dead spiders still in them. It is perhaps because of the many archeolog- ical discoveries in arid countries that we have become accustomed to think of the agents of the weather as working slowly only where there is little or no moisture, but the wonder- fully preserved paintings, engravings and clay models which are to be seen in the moist caves of southern France and northern Spain, and which antedate the works of the Egyptians by thousands of years, compel a modification of these views. When the polychrome paintings on the ceil- ings of the great chamber of the eave of Alta- mira, near Santander, Spain, were discovered, careful observers doubted their authenticity be- cause they showed so little evidence of great antiquity: the paint is so fresh that it ean easily be rubbed off with ‘the finger, the colors are probably nearly as bright as when first laid on, and there is no conspicuous flaking of the surface. Notwithstanding their modern appearance it is generally agreed that the paintings were made by paleolithie artists thousands of years before the pyramids were built or Babylon founded. In ithe cave of Combarrelles and in other caves in the Dordogne region of southern France the same absence of conspicuous weath- 2 Bull. Metropolitan Museum of Art, XV, De- cember, 1920, pp. 12-40. DECEMBER 8, 1922] ering is marked: the only obvious change in . the engravings made by paleolithic artists is that the incisions have taken on the buff color of the rock and are no longer white as when first made. In the cavern of Tue D’Audoubert on the estate of Count de Begouen, near St. Girons, in the Pyrenees, is an even more remarkable example of lack of disintegration. In this cave are the clay models of bison which are in nearly as perfect condition as when made. A clay model is almost a synonym for the ephemeral for the reason that a short exposure to ordinary air causes it to dry and erack, and excessive moisture causes it to collapse. These models of bison are in fact slightly cracked but with this exception are unchanged. It is possible that the cracks were formed within the first few weeks after the figures were mod- eled and that none has developed in the 18,000 to 30,000 years that have followed. This seems incredible, but ‘the proof of very great age ap- pears to ‘be well established. The conditions under which the art of pale- olithie man has been preserved almost un- changed for thousands of years are to be found in the uniform temperature, lack of sunlight, and absence of circulating ground water. Although the rock in the Altamira cave is sat- uvated there has been slight movement of ‘the ground water and consequently little solution or deposition has been’ possible. In the cave of Tue d’Audoubert there is now some solution and ‘the composition of the water which drips from the roof of the cave has changed slightly as is shown in some of the stalagmites which after being built by lime deposited from the water now have crater-like depressions in their summits showing ‘that the water is at present under-saturated. It is probable, however, that the moisture content of the air has remained constant and ‘that, because of ‘this, the clay models have not disintegrated. The remark- 3 Comte de Begouen: ‘‘Les Statues d’Argile prehistoriques de la Caverne du Tue D’Audou- bert (Ariége).

SCIENCE 661 able preservation of the Egyptian wooden models to which reference has been made is due to uniform temperature, lack of sunlight and absence of moisture. The explanation of such remarkable preser- vation therefore involves no new principle as it is due to uniform temperature, absence of sunlight, and non-cireulation of ground water. These are, indeed, ‘the conditions under which, deep down in the rocks, the skeletons of the vertebrates of the past are preserved. Herpman F. CLELAND WILLIAMS COLLEGE THE BEGINNINGS OF AMERICAN GEOLOGY To THe Eprror or Scrence: In his letter, “The Beginnings of American Geology” (Science, October 27, 1922), Dr. Marcus Ben- jamin (doubtless quite unintentionally) makes a statemenit which is not only unsupported by faets but which most unjustly reflects upon the character and career of a distinguished Ameri- can geologist, a president of ‘the Geological Siociety of America, and also of ‘the American Association for the Advancement of Saience, and, I think, the most unselfish, modest and self-effacing man of science I have ever known. As in ‘these days whatever appears “in prinit” is hkely to become material for the future historian it seems worth while to correct the er- roneous statement. In his reference ito Dr. Newbenry’s connection with the Geological Survey of Ohio there oc- curs the phrase “owing |to the changes in po- litical administration in Ohio he (Newberry) found himself displaced by a subordinate.” Neither of the two statements dneorporated in this sentence is true. No one who had the good fortune to know Dr. Edward Orton, who was Newberry’s suc- cessor as director of the survey, will be willing to admit that there is the slightest foundation for what is implied in the last phrase; and those who are familiar with ‘the history of that peniod of ithe survey know that Dr. Newberry’s failure ito continue as its head was mot due to a change in political administration in Ohio. During twelve of the sixteen years covering the entire period in which Dr. Newberry may be supposed to have had any sort of connec: 662 tion with the survey, governors of the stalte were of the party which was in power when it was inaugurated through ithe interest and imitia-_ tion of President Hayes, himself twice governor during ‘those years. Nor is there any evidence to show an at- titude of personal unfriendliness itowards Dr. Newberry or the survey on the part of ‘the two governors belonging to the other political fac- tion, each of whom served one term. The plain truth seems to be that for the discontinuance of appropriations for the sup- port of the survey under his administration and for the final ending of it by legislative enact- ment in 1882, Dr. Newberry, himself, was large- ly if mot entirely responsible, though the finan- cial crisis through which the whole country was passing during the early 70’s doubtless had much to do with the limitations put upon its operations. The people of Ohio had been led to believe that the economic and especially the mineral resources of the state would be developed by ithe survey and it is mot suprising that ‘there was impatience when after the lapse of ten or fifteen years nothing of great value on this phase of tthe work had appeared. Instead there had been published elaborate reports upon paleontology, involving large ex- pense for beautiful (and valuable) plate illus- trations, the cost of which for a single volume being as much as $34,000. Afiter ithree years Ithe legislature modified the organization by creating a geological board consisting of the governor, school commissioner and the state treasurer, which was charged with the general supervision of the survey, though this had, apparently, little effect upon the pro- gram of its operations. Volume 4 of the series of reports was pub- lished in 1882, thirteen years after the begin- ning of the work and was devoted entirely to vertebrate zoology. In the meantime Dr. Orton, who had jbeen one of Newberry’s principal assistants, had been especially interested in the economic and mineral resources of ithe state, the extent of which was hardly realized at that time, and material for Volume 5 had been gathered. In April 1882 ‘the legislature made an appropria- tion for ‘the cost of publishing this volume SCIENCE [ Vou. LVI, No. 1458 and at the same time announced that “upon the publication of said Volume 5 the Geological Survey of Ohio is hereby declared to be com- pleted.” It was also provided in the same Act that the publication of this volume should be in charge of a geologist to be appointed by the governor. The governor, the Hon. Charles Foster, promptly appointed Dr. Orton, who had recent- ly resigned the presidency of the Ohio State University, which he had held from its or- ganization in 1873, in order (to devote his entire time to the professorship of geology in that institution. In 1884 Volume 5 was published, being de- voted almost entirely to coal. It has always been the most sought after publication of the survey and the reaction tto its appearance was a provision by the legislature “to extend and complete :the account of the economic geology of the state that was begun in Volume 5.” In 1888 Dr. Orton published a volume on petro- leum ‘and natural gas which has been esteemed as equal in value ito Volume 5. The survey became and has continued to be popular with the people of the state and it has ever since been “a going concern.” On the death of Dr. Orton in 1899 he was sue- ceeded by his son, Edward Orton, Jr., whose development of ithe ceramic interests and meth- ods of the state were of nation-wide importance. Desiring to devote most of his time to this special field he resigned in 1906 and was suc- ceeded by the present imeumbent, Professor J. A. Bownocker who had served as assistant geologist for several years, and who also fills a chair of geology an the state university. It is true that the fact of Dr. Newberry’s absence during a large part of each year, especially during the winter when ithe legisla- ture was in session, had a good deal to do with ‘the dissatisfaction which developed a few years after his work began. Although born in Con- necticut he was, at the age of two years, brought tto Ohio by his parents and the state in which he grew up and was educated always regarded ‘him as one of her illustrious sons. He was a paleontologist rather than a geolo- gist but if he had been tactful enough to place the emphasis of the earlier years of the survey upon those phases of it in which the people DECEMBER 8, 1922] were vitally interested the story of his connec- tion with it might have been different. As it was Ohio saw adjoining states rapidly develop- ing their mineral resources as the result of geo- logical surveys while her own organization seemed to be producing only beautifully illus- trated volumes concerning fossils. There are enough sins legitimately left at the door of state and national legislatures, im con- nection with their dealings with science, with- out adding to their number the failures and mistakes which should really be charged 'to men of science themselves. T. C. MenpENHALI RAVENNA, OHIO NOVEMBER 7, 1922 THE COLLOIDAL STATE Epitor or Science: It seems that one im- portant basis of the anomalous \behavior of matt- ter in ithe colloidal state of subdivision les in the fact that, in the colloidal zone, increase in dispersion is accompanied by a disproportion- ately large increase in kinetic activity of the ultramicrons, which reaches an extreme at atomic or molecular dispersion. The speed of motion of ultramicrons is itseif the resultant of several factors (including size, temperature, viscosity of dispersion medium, concentraition, free electronic fields, ete.), but at probably exercises a very considerable influence in re- actions where colloids are involved, e.g., dif- fusion, adsorption, enzyme action, ete. For some time I have been accumulating data bearing on ‘this question, and would be pleased to hear from any readers of SctpncE who know of pertinent experimental facts. Thus Zsigmon- dy (“Colloids and the Ultramicroscope”) has given tthe size of certain gold ultramicrons and Ultra- microspi¢c examination indicates that gel forma- tion involves aggregation with cessation of visible kinetic activity, and the zone of maxi- mum degree of colloidality (J.

JEROME ALEXANDER 50 East Torty-First STREET, New York City, NovEMBER 13, 1922 NOTE ON THE FUSARIUM WILT DISEASE OF BANANAS In the journal, Phytopathology, of Septem- ber, 19191, Dr. E. W. Brandes deseribed in detail his out-door pot inoculation experiment, demonstrating that Fusarium Cubense, EB. F. Smith is the cause of the very destructive wilt disease of ithe banana, heretofore generally known as the Panama disease. Since then there has been published in Java a paper by E. Gaumamm on a vascular disease of the banana?, in which the author attempts to discredit the work of American investigators of this dis- ease, but particularly that of Dr. Brandes. In a statement by Brandes, of which the writer has a typewritten copy, he reviews Gaumamm’s paper and points out various errors and con- fusion of facts. As the writer, while connected with the United Fruit Company, recently con- ducted an experiment of exactly the same kind as the one by Brandes above mentioned, it may be important to those interested to briefly describe this experiment and the results. The experiment was made just outside the Com- pany laboratory, in Changuinola, state of Bocas del Toro, Panama. In this case the common Gros Michel banana was employed, instead of the variety Chamaluceo employed by Brandes. Otherwise the two experiments were almost perfectly parallel except as to locality. This experiment was begun November 1, 1921. Twenty-five cement pots were employed, set in corresponding holes in the ground, and 1 Brandes, E. W., Banana Wilt. Phytopath. 9.

Sterilizing the soil was done by a Company railway engine, the soil in each pot being steamed two hours, at 110° C. Fourteen pots were thus sterilized and the remaining six were neither sterilized nor inoculated. All the pots were planted with one “bit?” of a banana tuber having two “eyes” and in seven of those sterilized these bits were in- oculated with a laboratory culture of Fusariwm Cubense, while the other seven were not in- oculated. two kinds of culture-mixed at time of applica- tion—one in corn meal decoction and the other in Ushehinski’s solution, both originating from rice tube cultures, three weeks previously. It was applied in quantity of about one liter to each pot. Already in February, 1922, one of the inoculated plants showed signs of disease. By April 1 every one of the inoculated plants was diseased and most of them were even then bad cases. Up to July 12, when the writer lefit Panama, no one of the plants in the in- oculated pots, either sterilized or unsterilized, gave any indication of disease. Besides the added interest that may be attached to this ex- periment, with a different variety of banana in a different locality, the writer is glad, and others will be, that it confirms the painstaking work of Dr. Brandes. It should ‘be added that Dr. J. R. Johnston, director of tropical re- search for the United Fruit Company pro- posed the experiment, in which the writer was also supported and encouraged by the manager, H. S. Blair, and by H. L. Peck, E. C. Adams, and other men of the Company.

DECEMBER 8, 1922] QUOTATIONS INSULIN AS A CURE FOR DIABETES On another page we print an important communication from the Medical Research Council relating to a promising remedy for diabetes recently discovered at Toronto. Dia- betes is one of the more serious afflictions of mankind, insidious in its beginnings, debili- tating in its course, and often fatal. At pres- ent the treatment is little more than an effort to prolong life by a regimen of habit and diet so arduous as to make it very irksome. Dr. F. B. Banting, a young physician attached to the University of Toronto, acting on the known fact that extirpation of 'the pancreas in dogs is followed by a diabetic condition, thought it possible that tthe secretion discharged into the blood by that gland might be the factor inhibiting the onset of the disease, and that its administration in some form might prove a remedy. Experimental work confirmed his theory, which has, in fact, been thought proba- ble for many years. A substance, to which the name “insulin” has been given, extracted from the panereas of the ox, pig or sheep, when injected into the veins of human diabetic patients has frequently given quick relief, and has appeared to lead towards cure. But the remedy ds still in an early stage. The exact constitution of insulin, as, indeed, of many other of the subtler animal essences, is still un- known; its preparation demands high skill and special methods; its administration must be watched by expert physicians. In the opinion of the medical faculty of the University of Toronto, of their American colleagues and of representatives of our own Medical Research Council, any premature exploitation of insulin might gravely disappoint the public, and even prevent the ripening of the hopes of these high authorities. It has therefore been decided to protect and control its manufacture and use in the United States and in Canada. Similar protection and control in this country have been offered to and accepted by the Medical Research Council. To protect the public and to perfect a great boon are objects which com- mand respect. But while recognizing that spe- cial circumstances may in ‘this case justify it, we are not entirely reassured about the meth- SCIENCE 665 od—a feeling 'that seems to have given an apologetic tone to the communication issued by the Medical Research Council. For it is proposed to patent the remedy—a course ex- cluded from the practice of the Pasteur Insti- tute. Pasteur and Metchnikov determined that their discoveries should be offered as a free gift to the world, although the possibilities of fraudulent or foolish exploitation ‘by others, of mistaken use, and even of employing the revenue from patents for further research were present to their minds.—The London Times. JUSTICE FOR THE PUEBLO INDIANS In formally protesting against ‘the passage of the Bursum Pueblo Indian Bill the American Ethnological Society took account only of the plain facts. It is a thoroughly vicious measure, designed to put a premium on fraud and ito commit the United States government to a sweeping raid on ‘the lands and water rights of the New Mexico Indians. -The council of the Peabody Museum of American Archeology and Ethnology of Harvard uses very moderate language when it calls public attention to “the iniquity and hardship” of the bill to the end that it be defeated. The Bursum bill was put through the Senate on the strength of misleading statements. The scheme could not be worked again. Full pub- licity would prevent it. For a little publicity has already rallied to the support of the cause of the Pueblo Indians disinterested persons and organizations that will not desert them or be lulled to sleep as the Senate was. These Indians, living peacefully in some twenty tribal groups, have steadily crowded off lands confirmed to them by the United States government ‘by outsiders having no valid titles. The government is bound to protect them as its wards, but it has failed ‘to do so. But as it turns out, the Pueblo Indians, though voteless, are not friendless. It wholesome sign that before they ‘had united in voicing their own protest against the Bursum bill, friends from many quarters had volun- teered assistance and accepted the burden of the fight in their behalf. Congress and the administration ean not afford to be indifferent been 1S) 666 to the flood of protest pouring in on them against this betrayal of the Pueblo Indians for the sake of a few New Mexico land-grabbers.— The New York World. SPECIAL ARTICLES SERIES REGULARITIES IN THE ARC SPECTRUM OF CHROMIUM THe detection of two sets of related triplets, by Meggers and Kiess, in ithe course of their work on the are spectrum of chromium, induced the present writers to undertake a more thor- ough examination of the spectrum, to find, if possible, other regularities which might lead to While a detailed discus- sion of the work has not yet been completed, enough has been found ito warrant the follow- statements. At least three sets of series whose members are triplets, occur chromium. series relationships. ing in the are spectrum of Of these, two sets are composed of wide triplets, and one set of narrow triplets. The wide-triplet series are parallel; that is, there exists a constant difference between the wave numbers of homologous members. Each component of the first member of the diffuse series is itself a narrow triplet. In the table are given data for the first members of the principal, sharp and diffuse series of the two parallel systems: SCIENCE [Vou. LVI, No. 1458 The narrow triplets which constitute the third set of series are characterized by the frequency differences Av, = 8.80 and Av, = 5.65. Sev- eral doublets in which each of these separations exists and also one with the separation, Ay = 81.37, have hkewise been found. These are suggestive of inter-series combinations. C. C.

American jade and its archeological bearing. Lantern: Henry 8S. WASHINGTON. Microscopie study of many jade objects from Chichen Itza, Copan and localities in Mexico shows that the material consists of a jade-like pyroxene and albite in different proportions; varying from pure pyroxene to nearly pure albite. The pyrox- ene is composed of jadeite and diopside, the com- bination forming a hitherto unrecognized mem- ber of the pyroxene group. Many chemical analyses have been made, amd these, as well as the microscopic thin sections, show that the albite is soluble in the diopside-jadeite up to a cer- tain amount, beyond which it crystallizes out sep- arately. In chemical and mineral characters the Middle American jades differ markedly from those of Burma and Tibet, the chief sources of Chinese jade. These differences, the occurrence of a complete series of the rocks, and the orig- inal pebble form of many of the American jade objects, indicate that the material of the Mexi- -can and Central American artifacts is of Ameri- can, and not of Asiatie, provenance; thus being adverse to the theory of southeastern Asiatic origin for Middle American races and culture. This American jade has not yet been found in place, but it is probable that it comes from toward the Pacifie coast, and two centers of pro- duction are suggested as probable, Oaxaca-Guer- rero in Mexico and Guatemala in Central America.

This paper reviews briefly some of SCIENCE 667 the results obtained in an investigation carried out during recent years with the aid of grants from the Carnegie Institution of Washington, and describes unpublished experiments which furnish a new line of evidence that these enzymes, in their chemical nature, either are proteins or con- tain proteins as essential constituents. While alike in this respect, these two starch-splitting enzymes differ markedly in some of their prop- erties and are undoubtedly different substances. Some of the chief points of resemblance and of difference are briefly summarized and the prob- lem as to the conclusiveness of the evidence re- garding the chemical nature of these enzymes is considered.

Saturated Bredig gold sols: H. T. Beans and L. B. Miuurr. Briefly summarized the paper will present the results of the continuation of our work on the study of the influence of electrolytes on.the composition and behavior of gold sols made by the Bredig method. We have found that a very definite quantitative relationship exists between the maximum amount of gold which cam be dispersed by the Bredig method, and the character and concentration of the electrolyte present. The paper will, therefore, consist in a demonstration of this relationship with curves and data which are in support of the conclusions. Experimental studies on the hydrogen electrode: H. T. Beans and L. P. Hammerr. A study of the practical application of the hydrogen elec- trode and of theoretical questions involved has shown that the hydrogen electrode must function not only as an inert electrode, but as a catalyst for the hydrogen ion reaction. Comparison of various methods for producing the necessary ac- tivity is of interest from the general point of platinum catalysis, and indicates the interesting problem of the potential difference between active and inactive electrodes. These results, together with the results of the study of the effect of oxygen upon tthe electrode have led to a specifica- tion of the necessary conditions for precise meas- urements in buffered solutions, and investigation of the difficulties inherent in the application of the electrode to unbuffered solutions has led to the determination of the reasons underlying these dif- ficulties, and to a new type of electrode which 668 gives satisfactory results in solutions of potas- sium chloride. The interdependence of solvent and solute in ionization phenomena: JAMES KENDALL and Matcoum M. Hartne. In a previous communica- tion (Kendall, Proc. Nat. Acad. Sct. 7, 56, 1921) it was shown that compound formation and ioniza- tion in solutions proceed in parallel and that sol- vent and solute play an equally active part in ionization phenomena. The present article dis- cusses the various possible ionic types which may be produced by the disintegration of compounds formed when two substances RX and R1Y are mixed. Rules are deduced for predicting the relative amount of each type in any particular case from the character of the radicals concerned, and these rules are demonstrated to be in ac- cordance with experimental results chosen from both aqueous and non-aqueous solutions. Some unusual freezing-point curves in fused salt mixtures: JAMES KENDALL, E. D. Critten- DEN and H. K. Minuer. In the course of a de- tailed study of the factors influencing compound formation and solubility in fused salt mixtures, by which 49 new double salts were isolated, some rather remarkable freezing-point curves were en- countered. Two illustrative examples are here de- scribed. In the first—the system A1Brg:NaBr— a two liquid layer region exists between 2.6 and 16.3 per cent. NaBr, and the freezing-point curve on either side of this descends from 95.4° to a eutectic point. The solid phase in equilibrium with the two liquid layers must consequently be a double salt of intermediate composition, unstable at its true melting-point but melting to give two immiscible liquids at 95.4°. In the second type of system, of which SbCl3:SnCly is an example, _ the two liquid layer region is metastable, but approaches so closely to the freezing-point ¢urve as to induce it to become almost horizontal over a very wide range of composition. Ferric hydroxide hydrosol: ARTHUR W. THOMAS and A. FRIEDEN (introduced by M. T. Bogert). A citraconic analog of quinophthalone: M. T. Bogert and K. Asano. The well-known dye quinoline yellow (quinophthalone) is prepared by the action of phthalic anhydride upon quinaldine. It is now found that citraconic anhydride does not condense smoothly with quinaldine, but that when the imide is used in place of the anhydride, a dye analogous to quinoline yellow results. Diaryl thiophenes and diaryl selenophenes: M. T. Bogert and J. P. Herrera. 2,4-Diaryl SCIENCE [Vou. LVI, No. 1458 thiophenes and diaryl selenophenes may be ob- tained in fair yields from ketone anils, of aceto- phenone anil type, ‘by fusion with sulfur or selenium.

The writer points out that every emotional effect transmitted by the singer or other musician through musie is con- tained in the sound wave. This can be inter- cepted and recorded with high precision and the musical effects may then be classified in terms of the measurable attributes of the wave; namely, frequency (pitch), duration (time), amplitude (intensity and volume), form (timbre). All mu- sical expression through sound may be expressed in terms of variables in these four factors. Undernutrition and its influences on the meta- bolic plane of steers: Francis G. BENEDICT and Ernest G. RirzmMan. Based upon experiences with humans, who voluntarily underwent ration curtailment, and upon the well-known inequali- ties in the feeding habits of wild animals, a group of 11 steers were subjected ‘to curtailed rations amounting to approximately one half of their normal maintenance requirements, for a period of about 140 days. Measurements of feces and urine and feed, as well as an extensive series of metabolism measurements inside of a specially constructed respiration chamber, made it possi- ble to study these animals intensively. The cur- tailed rations resulted in a distinct loss of nitro- gen and fat from the body, but the steers recov- ered their initial state by subsequent feeding with hay, concentrates or pasture. Although car- ried through the winter on an extraordinarily low metabolic plane, they suffered no permanent dam- age and all were subsequently fattened for mar- ket.

A general description is given of a method of external examination by which the several stages of the ovarian cycle may be defi- nitely located. The moment of discharge of the ovum from the ovarian follicle may also be ac- curately determined. The several stages of the ovarian cycle may be experimentally modified and ovulation temporarily or permanently suppressed. The type of modification may be recognized by a study of the structural reactions of the uterus and vagina which are indicated by the cellular composition of smears collected from the wall of the vagina. The ovary may ibe used as a very exact and valuable indicator for determining the general metabolic conditions of the individual. The mechanism of selective bacteriostasis: JoHN W.

The paper gives the general results of a mathematical study of the SCIENCE 669 relations exhibited in the socalled crossing-over of the genes, and compares these with those bound to occur if the genes are arranged in series and there is interference between breaks at points near together in the series. The ob- served ratios fall into a peculiar and complex system; by means of a mathematical formula it is shown that this entire system, even to details, is, in all essentials, a necessary result of the serial arrangement with a certain extent of inter- ference. The marked changes that would result from different extents of interference are like- wise shown. A new type of uroleptus formed by permanent fusion of two conjugating individuals: Gary N.

RicurmMyrr (introduced by Frank M. Chapman). The various ¢ol- ors on the petals of flowers and, indeed, the petals themselves are rather generally believed to have arisen in connection with the pollination of flow- ers by insects. A few experiments, including some made recently, indicate that insects respond definitely to ultraviolet rays. This suggested an investigation of the reflection by flowers of ultra- violet rays. It was found that some flowers show ultraviolet while others do not, just as some show blue while others do not. If flower colors are important in connection with pollination by insects, its seems that not only the visible spee- trum but also the ultraviolet should be con- sidered. Recent discoveries of fossil vertebrates in China and Mongolia: W. D. Marrurw (introduced by Frank M. Chapman). Important — fos- sil mammal faunas have been recently discovered in China by the Chinese Geological Survey and American Museum party. The American Mu- seum’s Asiatic Expedition has also been extraor- dinarily suecessful in Mongolia this summer. Three important mammal faunas, Eocene, Oligo- cene and Pliocene were discovered, also. a rich Cretaceous dinosaur fauna. Large collections 670 were secured, including complete skulls and skele- tons and their study is expected to throw much light on the origin and dispersal of the higher vertebrates and of men. The Whitney South Sea expedition of the American Museum of Natural History: ROBERT CusHMAN Murprny (introduced by Frank M. Chapman). For more than two years the Mu- seum has been conducting ornithological investi- gations in Polynesia.

Mutations among birds in the genus Buarre- mon: FRANK M. CHapmMan. From a study of the 160 specimens of Buarremon brunneinucha and B. inornata in the American Museum of Nat- ural History the following conclusions are reached: (1) That Buarremon inornata is a rep- resentative of Buarremon brunneinucha. (2) That the variations in pattern and color occurring in the underparts of brunneinucha, throughout the range of that species, are individual and are not due to age, sex or season, to climate or other ob- servable environmental factors. (3) That isola- tion, partial or complete, has alone supplied the conditions needful to the development and estab- lishment of these characters as the specific at- tributes of Buarremon inornata.

The photo-luminescence of flames: E. L. Nicuots and H. lL. Howrs. When flames con- taining salts of Na, Li, Ca, Ba, Sr, ete., are ex- posed to light the bright bands in their spectra, in general, are enhanced. The effect, although large compared to ordinary fluorescence, forms a small part of the total brightness of the flame and can not be readily detected except by spectro photometric methods. As in ordinary photo- luminescence excitation is by wave-lengths shorter than those of the band itself. There is a meas- urable quenching by exposure to the longer wave- lengths and specifically to ight identical with the SCIENCE . terior [ Vou. LVI, No. 1458 band.

This paper discusses some of the problems in physies and in engineering which were solved in the course of this development, particularly those which relate to the construction of glass and metal apparatus suitable for use with these high powers. The paper will be illustrated by samples of the tubes and by slides showing the general features of their construction. Carrier type multiplex telephony and teleg- raphy: E. H. Cowpirrs. The underlying principles of carrier are discussed particu- larly as they apply to carrier telephony, first, where a single channel of communication is pro- vided, and secondly, where a number of chan- nels are provided over the same pair of wires. Apparatus is shown illustrating the physical steps in the process of transmitting speech from one terminal station to the other. Particularly the perfiormance of filters in dis- -criminating against the passage of currents out- side of the band which they are designed to transmit is demonstrated. In these demonstra- tions use is made of a loud speaking telephone. Spectrum energy curves of the stars: CHARLES G. ABBOT. Affine geometries of paths possessing an in- variant integral: LutTHER P.

THE TREND OF AVIAN POPULA- TIONS IN CALIFORNIA THERE is one besetting temptation to which any student fairly advanced in the exploration of his chosen field would seem justified in yield- ing. This temptation is to hold up to close serutiny any stmking generalization given wide publicity, save it be from the most authorita- tive souree—to see whether it be really founded in fact. A case in point has to do with avian populations. It has been stated or at least implied with increasing frequency in late years, in various publications, especially in those emanating from organizations concerned with bird pro- tection, that serious decrease is taking place in our bird life, and that this decrease is due to the thoughtlessness or perfidy of man and is preventable. These statements and implica- tions are being expressed mot only with regard to the longer and more thickly settled eastern United States, but with regard to the west in general, and to California. Confessedly with some a priori doubt, but with a view to testing fairly the truth of these dicta, I have under- taken an inquiry into the situation in our own state, for the purpose of finding out what tthe facts are—of ascertaining whatever changes in our bird population may, indeed, have become apparent, and the causes therefor. To begin with, of course, terms must be de- fined. In using the word “decrease,” or its opposite, “increase,” in this connection, one of two distinet ideas may be in a person’s mind. He may refer to the number of species, or he may refer to the aggregate number of indi- viduals. Or, both of these ideas may be held, in more or less vague association. To take up the first concept: There is no question whatsoever that a certain few species of birds have become nearly, or quite, extinct, as far as California is concerned, within ‘the 672 past seventy-five years; as examples, the trum- peter swan and the whooping crane. But, com- pensating for these losses, there have become newly established within our territory during that same period some species of foreign souree; as examples, ring-necked pheasant and English sparrow. Checking up the species of both categories, we can reach but the one con- clusion that, as yet, so far as concerns tthe state as a whole, there has been no real reduction in the total number of species; our known avi- fauna at the present moment totals 582 species and subspecies; I am aware of no good ground for supposing ‘that 1f was one unit more or less, seventy-five years ago. If, however, we narrow our attention to given restricted localities, we are confronted with evidence of real and great reduction in species, up to even forty per cent. of the original num- ber, I figure, in some places. It is this local reduction in species, most apparent naturally in centers of human population, that has im- pressed so strongly the ardent advocates of the various sorts of bird protective measures. An entirely different phenomenon, as already intimated, is comprised in the fluctuation of aggregate populations, irrespective of the various species, few or many, represented in them. On this point, my impressions are strong that, throughout the country at large, wherever human influence has had any marked effect, there has been increase in the bird life. In some localities, as pointed out below, this increase may reach as much as tenfold. My reader will at once demand something more tangible than “impressions.” And I am compelled regretfully to admit that figures seem to be wanting. actual record of censuses taken fifty years ago, or even twenty-five years ago. This is unfor- tunate; and it is to be hoped that further lapse of time will see an improvement in this situa- tion. basis or a unit-of-time basis, are now being taken and recorded. The student of ithe future, let us hope, will have plenty of statistical data upon which to base final conclusions. It seems, then, that, in this discussion, I must fall back upon less tangible classes of Numerical censuses, on either an areal SCIENCE We have no [Vou. LVI, No. 1459 evidence—upon memory and upon inferences from other categories of facts. Before citing this evidence, however, let me introduce some theoretical considerations. It is a recognized, established principle that the presence in a region of any given bird species is absolutely dependent upon, first, proper food supply, second, the right kind of breeding places, and third, appropriate cover or protection for individuals—each of these conditions as bound up with the inherent struc- tural features of the bird under consideration. Mark ‘that there are three of ‘these factors, each and all of them essential; if any one of them in a given region becomes effaced, the bird in question can no longer exist there. There are, of course, other factors essential ito avian ex- istence, but they affect all the birds of a given fauna alike. We can deplore, wring our hands, and suffer agonies of regret, but to no avail— except as active steps be taken to restore the critical condition. As a matter of cold cireum- stance, a bird’s disappearance in a given local- ity may be irretrievable—as happens where man has densely settled a territory and inci- dentally or purposely destroyed certain of its natural features unnecessary or inimical to his own existence there. Chop down all the trees and there can be no more woodpeckers; drain the lakes, ponds and swamps and there can be no more water birds; remove the chaparral, and wvren-tits, bush-tits and thrashers ean no longer find proper food and shelter. Cement up all the holes in the campus oaks and there will be no more plain titmouses—for the reason that roosting and brooding places essential to their existence are no longer to be found. Each bird species native in a given region has a different and very special combination of requirements. Existence of each is really de- termined by a very slender thread of cireum- stances which can, in most species, be broken readily. Differences must, of course, be recog- nized in the degree of hardihood, or of via- bility, in the various species of birds—some are on the ragged edge of extimetion, this con- dition in part due to inherent reduction in spe- cifie vigor—the race is naturally playing out, we say; others are hardy, with a large reserve DECEMBER 15, 1922] of specific energy; some can even stand what may aptly be called ecologic punishment. In any one locality the field observer comes to recognize a few or many rather intangible units which he calls “ecological niches’”—sep- arate cubby-holes or dwelling places or habi- tats (in the narrowest sense), which differ in essential respects from one another. If the topography and vegetation be varied, there are many of these niches; if more uniform, there are few of them. Hach niche is separately occupied by a particular kind of bird, and the locality supports just as many species of birds as there are niches; furthermore, the numbers of individuals of each bird are correlated directly with the degree of prevalence or dom- inance of the niche to which that particular bird is adapted. In other words,—and here is the crux of the idea,—both the number of the species and the number of the individuals of each species, in a locality, are directly de- pendent upon the resources of ithe environment, from an avian standpoint. The same notion holds, of course, for all other animals, including Homo. Rate of reproduction in any species has been established down through past time so as to supply the population needed to keep the ap- propriate niche filled. This rate varies with the natural prevalence of the niche, and with the hazards to which the niche occupant is ex- posed. Not only that, but a wide mangin above the normal need is provided to meet that ex- treme emergency which may arise but once in a thousand generations; in other words, there is produced a large surplus—an apparent great waste—of individuals over and above what is needed to keep the appropriate territory fully populated, in order to save the species from extinction at some critical moment; for ani- mate nature abhors a vacuum no less than does inanimate nature. A recent writer in SCIENCE (LV, May 12, 1922, pp. 497-505), Professor A. F. Shull, has, in another connection, called this fact of over-production the “factor of safety.” He says: “The entire struggle for existence is based on the principle that security and advancement are best assured through wasteful over-production.”’ The employment of SCIENCE 673 the factor of safety, I would say, is a manifest device on the part of nature ito insure con- tinuity of species, and hence also to make evo- lution possible. A British ornithologist, Mr. H. E. Howard, has lately put out a book in which he elab- orates exhaustively the idea of the importance of territory to bird life. Kind and availability of territory determine the kind and amount of bird life. In final analysis, when a territory, or, as I would express it, more explicitly, an ecological niche, becomes full, and this im normal times comes to pass very quickly, the individuals within the species constitute each other’s worst enemies. Continued conflict for space—for a piece of land, for an area of meadow, for a section of tree-trunk, for a given unit of volume of twiggery or foliage—is plain to be seen by any diligent observer of bird life. The resulting pressure for territorial expan- sion reminds one of the same pressure obtain- ing among humans; only, among birds, there is no organized warfare. The process is one of struggle as between individuals or pairs of individuals, between neighbors, indirectly, per- haps, as a rule; but also, often, directly, by personal action. The most fit to compete, sometimes the most fortunate, will survive; the less fit will be eliminated. The survival pros- pects of each single individual are small. Vast numbers of individuals are poured in. The “safety factor” in numbers is there in order to insure the persistence, and continued adaptive improvement, of the species. Let us now return to more matter-of-fact considerations. What have been some of the effects of the settlement of California by the white man, upon the environments of birds? Have any ecological niches been effaced? Have any niches been added? Have some been re- duced in prevalence and others increased in prevalence, relatively? What have been the effects upon ithe niche-oceupants? Perhaps the conspicuous changes wrought in the appearance of the landscape in the southwest have resulted from irrigation. In substantiation of this statement, many of my readers can doubtless appeal to his own memory. I, myself, recall traversing long most 674 stretches of the San Joaquin Valley twenty- five years ago, which were then merely arid plains. The vegetation consisted of xerophi- lous grasses and herbs, with here ‘and there traets of lupine or atriplex bushes. The birds observed were scattering horned larks, fewer meadowlarks, and occasional burrowing owls; it being winter, there were more numerous Savannah sparrows and, in rain-dampened places, pipits. Knowing what I do now about censuses, I doubt if there were then more than one bird to the acre, on an average, probably much less than that ratio. Now, regarding the same territory, it would be hard to exaggerate the amount of change in vegetation which has resulted from the water- ing of the ground. Orchards, alfalfa fields, green pastures and streams of running water lined with willows, completely occupy the land. Instead of a very uniform type of environ- ment, with only a few niches and correspond- ingly few species of birds, one finds, upon analysis, a great variety of niches and a much increased number of bird species. What is more, the numbers of individuals are vastly larger. To be sure, the horned larks and bur- rowing owls are gone. But the meadowlarks have multiplied; and, in addition, one sees great numbers of Brewer blackbirds, of mock- ingbirds, goldfinches, swallows, phobes and killdeers. I esitmate the mean population over large areas of the San Joaquin in April, when the lowest ebb for the year is reached, at 10 per acre, or over 6,000 per square mile. Here, obviously, the conditions for abundant avian population have been markedly improved by the coming of the white man with his methods of cultivation. Even more spectacular has been the faunal change wrought by irrigation in Imperial Valley, where luxuriant vegetation with result- ing abundance of bird life has replaced the original sparse vegetation of the desert which supported relatively little animal life. Another biotic modification is brought about by deforestation. Close stands of coniferous trees are replaced by “slashes,” by open young growths, or by mixed brush land and trees. Dense forests, it is well known, are sadly lack- SCIENCE {[Vou. LVI, No. 1459 ing in bird population. The removal of the forests has meant, of course, the disappearance of a few, specialized avian tenants. But in their place, occupying the clearings and mixed growths, is a much greater population both as to individuals and species. Kinglets, pileated woodpeckers, and hermit thrushes may have disappeared; but fox sparrows, chipping spar- - rows, spotted towhees and a host of other birds of like habitat preferences have come in. Cer- tain little niches have been done away with; but the change in the nature of the territory at the hand of the lumberman has resulted in there being many more, new niches; each of these, evidently, of greater amplitude, of great- er supporting power. Very definite change in the other direction has been that made as a result of the draining of swamp lands. Many species thereby have been eliminated, locally, many more species than oceupy the reclaimed land; and, further- more, I feel sure that the numbers of indi- viduals, too, have been reduced, though not in so large proportion. As instances, I would refer to Nigger Slough and Gospel Swamp in southern California, and to the region at the confluence of the Sacramento and San Joaquin Rivers in west-central California. A swamp is really a very complicated type of environment; within it usually may be recognized many “niches” and a correspondingly large number of avian occupants. Among these are the herons, rails, gallinules, song sparrows, yellow- throats and tule wrens, and, if there be open water, coots, terns and several species of ducks. The most serious adverse effect of the human occupancy of California upon bird-life thus far has, I believe, resulted from this reclama- tion of the swamp lands. But, if you will re- sort to memory, or examine a topographic map, you will observe that the total area here in- volved is very small compared with the terri- tory that has been affected oppositely, by irri- gation. Irrigated territory, moreover, is sub- ject to continual and much farther spread, while the possibilities of drainage are almost exhausted. Other modifications of primitive conditions as a result of the white man’s occupation of DECEMBER 15, 1922 the country are as follows: By the clearing of brushlands, for example, in San Fernando Valley, Los Angeles County; by the planting of trees, afforestation, as exemplified in the groves of trees around the Greek Theater and on the Berkeley hills; by the cultivation of dry grasslands, as on the coastal benches of San Diego County; and by the formation of storage reservoirs and canals, which, irrespec- tive of the lands which they water, bring into existence aquatic and riparian types of vege- tation conducive to an abundant bird life. Some of these it will be noted, check against one another, so that status quo, in part of the country, tends in some measure to be main- tained. In general, then, my contention is that there has been, on the average, as a result of the settlement. of California, a marked increase in our bird population. Bird life at large has ben- efited—and this in spite of various adverse fea- tures which also have been imposed. sage should be, therefore, one of optimism to the bird-lover. It is to be understood that I refer to birds of all groups together; not to any particular group. There are vastly more of the so-called “song birds,’ numerically, than there are of the “game birds” and “birds-of- prey.” ously depleted, unquestionably, from various causes associated with man; but probably not My mes- The latter two groups have been seri- more than ten ‘per cent. of our original bird population consisted of game birds and birds- of-prey combined. Permit me now to link up with current no- tions and beliefs in regard to the status of bird life some of the ideas that I have been en- deavoring to express. In a lange proportion of cases the reduction or disappearance of a cherished species of bird, locally, such as may have been laid to other entirely different causes, has really been due simply and inevitably to the reduction or complete effacement of the kind of habitat the bird must have for its ex- istence; in other words, its ecologic niche has been reduced in volume, or destroyed. No one could help it; nor can any one now stay the process, except by restituting the lost factor; for example, when land is bought or otherwise SCIENCE 675 preserved from human use and devoted to the use of the birds, as in national or state bird or game reserves. Of course, in certain areas, such as national parks and forest reserves, the environments and the birds occupying them are being preserved anyway, incidental to other interests. The tendency among sentimentalists has usu- ally been to seek out a cause for the disappear- ance of birds that is directly concerned with their fellow men. The hunter, the boy with the sling shot, the collector, any one of them or all, loom wp as the “exterminators of birds”; whereas, in truth, I believe, it is only in rare cases and then only very locally, that these agencies have had any effect at all. In other words, if my line of reasoning has been cor- rect, legal protection, with ninety per cent. of our bird species, is absolutely unnecessary, save as it applies, and then properly so, to parks, the suburbs of cities, and to logically constituted game and wild-life preserves, where shooting for any purpose is out of order. Recall the geometrical ratio of reproduc- tion, and the consequent powerful potentiality for recovery on the part of bird species. Let me cite here the case of the eastern bluebird as reviewed by Mr. P. A. Taverner in a recent number of the Canadian Field-Naturalist (XXXVI, April, 1922, pp. 71-72). In the winter of 1895-96 a cold wave swept the South Atlantic states, the sole wintering ground of the eastern bluebird. As a result, famine and death reduced the total bluebird population almost, but not quite, to the vanishing point. But in five years the species had recovered “from almost nothing to practical normality.” After reaching normal, a “saturation point of population” for the species, it ceased to in- crease; or, as I would express it, its ecologic niche, of fixed amplitude, was then full. The operation of the “factor of safety” not only saved, but very quickly brought ‘back, the species. Another catastrophe, recorded by Dr. T. S. Roberts (4uk, XXIV, 1907, pp. 369-377) hap- pened to a sparrow-like species, the Lapland longspur, in southwestern Minnesota, the mid- dle. of March, 1904. It was migration time, 676 and a peculiarly wet and thick snowstorm that occurred during the night of the thirteenth is thought to have overwhelmed the birds when in flight high overhead, soaking their plumage and dazing them. At any rate, great numbers hit the ground with fatal violence. In the morning dead and injured birds were to be seen over a wide stretch of country; on the frozen surfaces of two lakes 750,000 dead long- spurs were counted, by the method of laying off sample units of area and checking the birds to be seen on ‘these units. But in spite of this spectacular destruction of individuals the Lap- land longspur was not reported the following years in the winter range of the species (Kan- sas, ete.) as obviously less numerous than usual. Did not the ability of the species to recover from this extraordinary calamity rest in the “factor of safety’? There is good reason to believe that release of intra-specific pressure on the breeding grounds of a species is accompanied by greater productivity on the part of the remaining pop- ulation. he survival chances for the young are greater where the safest type of nesting places is available to all the adults seeking to breed, and where congestion of population, and consequent drain on available food supply, has been relieved. Also, towards the end of the year, when the annual pinch of food scarcity comes into play, in the winter range, a larger proportion of maturing individuals than usual will survive. In other words, from one point of view, calamitous reduction of population benefits the immediately oncoming generations. Let me center attention now upon the sig- nificant fact that certain of our birds are, and always have been, totally unprotected by either law or sentiment—jays, crows, linnets, shrikes and blackbirds. The rate of annual increase in those species is no different, in so far as I am aware, than it is in the vireos, warblers, mockingbirds, tanagers, and purple finches, which latter are looked upon as desirable song- birds. Yet the former are holding their own just as well as the latter, protected, species. Their numbers are always kept up to top- notch commensurately with the prevalence of their niches. They have reached the maximum SCIENCE [ Vou. LVI, No. 1459 population possible to them, consistent with the nature of the country, and they hold to it. We all know of the enmity of orchardists, and agriculturists, and sportsmen toward linnets, blackbirds and blue jays, respectively. Now and then, and there is a case on record as far back as thirty years ago, “blue jay hunts” are held; in one lately recorded in- . stance, at Hollister, San Benito County, 1,531 California jays were killed in one day, in a prize competition for the destruction of so- called “vermin.” Incidentally, you will note that feel particular animosity toward any competitor or rival in their own field! They are right after anything that can be called “vermin” from their standpoint. As far as we can see, as a result of such cam- paigns—shooting of blue jays, netting of black- birds, and poisoning of linnets—there has been only a very temporary and local reduction in the numbers of these birds; two or ‘three sea- sons bring them back ‘to normal: that is, to the maximum numbers which the amplitude of their respective niches will warrant. Bird population, in kind and quantity, is conirolled primarily by conditions of habitat. It is a matter of food and shelter. The natural history collector, as a factor against birds, is only an exceedingly minor influence, one which like all the others, is allowed for by the “factor of safety.” My readers will begin to suspect that I have become sensitive because of the inveighing that certain well-meaning but unin- formed people have undertaken against the killing of birds for specimens. I admit the score. sportsmen JOSEPH GRINNELL MUSEUM OF VERTEBRATE ZOQLOGY, UNIVERSITY OF CALIFORNIA ARE PERMANENT DISTURBANCES OF EQUILIBRATION INHERITED? Tue writer of this note has just brought to completion a long series of studies upon the mechanics of equilibration in the white rat. During the course of these studies certain facts appeared which, though incidental to the orig- inal problem, may be of importance in the DrcEMBER 15, 1922 field of genetics. The facts were observed un- der the following conditions. As a part of our method, we found it necessary to rotate white rats day’ and night in small revolving cages over a period of several months. The eylindri- eal cages, less than a foot in diameter, were ro- tated in a horizontal plane, some at sixty and others at ninety times a minute. Several months after this series of continuous rotations began, a part of the subjects were removed from the rotating cylinder (a) in order to make observations on their behavior subsequent to their long continued rotation, and (b) in order to make room for litters which were born from time to time within the cylinders. Several weeks (the time has varied from individual to individual) after these first subjects had been removed from ithe rotating cylinders, it was discovered that permanent changes in bodily movement and posture had taken place. The most striking changes were (a) circular move- ments about the nest, usually in the direction of the long continued rotation, and (b) a de- cided turning or twisting of the head to the right or to the left. It was discovered, more- over, that these changes in posture were oc- casionally accompanied by swellings and dis- charges from the region of the ear, and more frequently, by decreasing bodily tonicity and finally by death. Further search revealed the fact that this state of “disequilibration” was accompanied by important changes in the character and in the duration of the ocular movements following short rotation periods (20 turns in 10 seconds). Before ‘the appearance of this state of “dis- equilibration,” a few of the subjects with a long history of rotation were mated with other ro- tated and unrotated individuals solely for the purpose of adding to our experimental stock. Curiously enough, however, individuals began to appear in successive generations presenting the same types of disequilibration observed in the parents. That is to say, rotated individuals mated weeks after having been taken from the revolving nests gave ofispring a part of which were disequilibrated in the same manner as their parents. Subjects of this kind have con- tinued to appear at various intervals during SCIENCE 677 the past two years. They have even been dis- covered in the third generation after rotation. Up to this time about sixty disequilibrated in- dividuals have been counted in a total popula- tion of approximately five hundred. Unfortunately, the demands of the experi- ments upon equilibration made it impossible to investigate adequately the genetic implications involved in these materials. Nevertheless, the facts as such were considered striking enough to warrant their presentation at a meeting of the Society of American Naturalists in 1921. The questions and suggestions received at that time have led to the conclusion that the biologi- cal aspects of the problem should be established and that definite attempts should be made to discover (a) whether the stock in our labora- tory may not have given one or more mutations or segregates which, in turn, became the pro- genitors of the curious individuals still appar- ent; (b) whether an experimental method of modifying the function of an important organ has been accidentally discovered; and (ce) whether actual inheritance of such an acquired bodily change can be demonstrated. The first suggestion seems improbable because no similar rats have appeared in a large related control stock running along with the experimental stock. Furthermore, the character of the dis- equilibration has appeared to be regularly de- pendent upon the direction in which the an- cestors were rotated. With respect to the third problem, namely, a possible demonstration of the inheritance of acquired vestibular changes, a number of biologists have offered the sugges- tion that long continued rotation may have induced the production of toxins or of other substances which, in operate after the fashion of the lens anti-bodies, recently de- scribed by Guyer and Smith. It seems desirable, then, to institute a new series of rotations with a new stock and to use, as well, other means of inducing disturbances in the semicircular canals so that more reliable evidence for or against the apparent cases of inheritance in our own stock may be discovered. It is also desirable to know what morphological and structural changes have taken place in the vestibular areas subsequent to long-continued turn, 678 excitation. Fortunately, Professor J. A. Det- lefsen, who has cooperated with the writer ever since the first eases of disequilibration appear- ed, is able to devote a sabbatical year at the Wistar Institute to the further investigation of the facts above described. C. R. Grirrita DEPARTMENT OF PSYCHOLOGY, . UNIVERSITY OF ILLINOIS THE USEFULNESS OF ANALYTIC ABSTRACTS THE various ways in which preliminary ab- stracts should be of service to scientific readers were pointed out about a year ago!, but whether such abstracts as actually prepared and pub- lished would ‘be worth while could be deter- mined only ‘by experiment. This has been done. After analytic abstracts had been ap- pearing in the Astrophysical Journal and the Physical Review? for over two years the fol- lowing return post-card questionnaire was sent by the chairman of the Division of Physical Sciences of the National Research Council to each reader, with the request that he under- score in each parenthesis the word or words which represent his answer to the question im- plied: . I look through (the Astrophysical Journal, the Physical Review) regularly. Before reading the articles, I read the abstracts (always, usually, sometimes, seldom, never). Instead of reading the articles, I read the abstracts in (many, some, few, no) cases. The abstracts have helped me understand the articles in (some, few, no) cases. The abstracts have proved useful in locating in- formation in (some, few, no) eases. I read the subtitles in the abstracts first (sometimes, never). I find the subtitles of value as an index of the abstract (sometimes, never). The abstracts in general give (too much, too little, about enough) information. I think they should be continued (yes, no). IT have the following suggestions to make: 1“* Scientific Abstracting’? by G. S. Fulcher, Science 54, 291, September 30, 1921. 2 The preliminary abstracts in the Physical Re- view are called ‘‘Synopses’’ to distinguish them from the abstracts of papers presented at meet- ings which are printed in connection with the proceedings of the Society.

Since some replies are incom- plete, the sum of the percentages is usually less than 100. 1.

In what ways? According to the testimony of the readers: “They are great time savers’; “They frequently give all information necessary about the articles’; “They double a man’s range of reading.” Moreover, the ab- stracts have ‘been copied verbatim in Science Abstracts and have thus reduced the labor of preparing that abstract journal by ten per cent. The abstracts have therefore to some extent fulfilled their purpose of saving the time of scientific men. How about other sciences? Are astronomy and physies essentially different from chem- istry, botany, zoology, geology, physiology, ete., in their methods of disseminating scientific information? If 93 per cent. of the readers of these astronomical and physical journals find that preliminary abstracts are useful to them, would not the great majority of other scientific readers also find such abstracts use- ful? The responsibility resting upon the editors of other scientific journals is clear. Now as to the nature of the abstracts which _ should be provided. The abstracts which have been appearing in the Astrophysical Journal and Physical Review are of the analytic type developed by the National Research Council.® They aim to give a complete description and adequate summary of the results reported in each article. The replies to the question: 6. Is the amount of information given, in general, about enough, too little, or too much? about enough 79.8 per cent. of readers. too little - 6.7 per cent. of readers. too much 4.8 per cent. of readers. 91.3 per cent. these replies indicate that the abstracts, aver- aging from 5 to 6 per cent. of the articles, have been of about the right length, and it is not believed they could be made much shorter with- out considerably decreasing their value. A distinctive feature of the abstracts is that they contain italicized subtitles which give 3 Deseribed in ferred to above. “‘Scientific Abstracting’’ re- SCIENCE 679 the various subjects involved more completely and precisely than in general it is possible for the author’s titles to do. One purpose of these subtitles is to enable a reader who is not inter- ested in the subject indicated by the author’s title to determine by glancing through the sub- titles whether something of interest to him has not been incidentally included. Until readers became accustomed to these subtitles, however, it was to be expected that most readers would consider them more of an annoyance than a help; but the following replies show that a surprising percentage of the readers have already found the subtitles useful: 7. Do you ever read the subtitles in the ab- stracts first? sometimes never 64.1 per cent. of readers. 17.5 per cent. of readers. 81.6 per cent. 8. Do you ever find the subtitles of value us an index of the abstract? sometimes 63.0 per cent. of readers. never 12.7-iper cent. of readers. 75.7 per cent. Since the subtitles also serve the purpose of assisting in the compilation of a complete sub- ject index and tend to insure more complete abstracts, it is believed this feature should be retained. Only three readers definitely objected to the form of the analytic abstracts. It is the practice of both these journals to submit all authors’ abstracts to an abstract editor to be revised or if necessary rewritten, in conformity with the standards adopted. While a few authors have objected to having their abstracts “robbed of individuality,” a number of readers specially called attention to the importance of having the abstracts edited so that a uniform standard might be main- tained. It can safely be affirmed that since most authors are inexperienced in writing ab- stracts and also differ widely in their ideas of the function of the abstract, authors’ abstracts if not thoroughly edited are sure to fall far short of rendering the service which prelim- inary abstracts should render, even if detailed instructions are furnished. But after the edited abstracts begin to appear regularly, they 680 gradually establish a standard to which authors will conform more and more closely as time goes on, and therefore the amount of editing required will become less and less. Finally, mention should be made of the sug- gestion of several readers that larger type be used for the abstracts than has been the cus- tom. Since more people read the abstracts than read the articles, it would seem obvious that the type of the abstracts should be at least as large as that of the articles. It should not be long before all scientific journals, in fulfilment of their duty toward their readers, provide carefully prepared pre- liminary abstracts of their scientific articles. There can no longer be any doubt of the value of such abstracts. It remains only to over- come the practical obstacles to the introduc- tion of the new policy. In conclusion we desire to express our thanks to the 805 readers whose cooperation gave us the information herewith reported. Gorpon 8. FuLCHER CoRNING GLASS WORKS © SCIENTIFIC EVENTS CONSERVATION OF THE RESOURCES OF THE PACIFIC The following resolutions were unanimously adopted by the Pan-Pacifie Union Commercial Conference, meeting at Honolulu on November 7, 1922: Whereas, It is known that many valuable spe- cies of marine mammals such as fur seal, sea otters, elephant seals and whale, and many spe- cies of important food fishes such as salmon and halibut, formerly occurred in the Pacific in such vast numbers as to constitute the objects of fish- eries whose annual products were worth more than one hundred million dollars, and Whereas, Nearly all of those great natural re- sources have been seriously depleted, many of them even to commercial extinction, through greed and short-sightedness and ill-comsidered fishery methods, and Whereas, It is known that small remnants of fur-seal and sea-otter herds and small numbers of whales and of other commercially valuable species still remain in certain places, and Whereas, The rapid recovery of the Alaska fur- SCIENCE [Vou. LVI, No. 1459 seal herd in the short period of ten years from complete commercial ruin to an annual produc- tion of more than one million five hundred thou- sand dollars, as a result of the international fur- seal treaty of 1911, demonstrates conclusively the wonderful recuperative power of such depleted natural resources of the sea under international cooperation, and justifies the belief that other depleted fisheries can be rehabilitated through similar cooperation among the nations concerned, and Whereas, It is conservatively estimated that these resources when rehabilitated will yield to the world a regular annual product of more than one half billion dollars in value, therefore be it Resolved, That the Pan-Pacifie Commercial Conference strongly recommends that the various countries bordering on, or interested in, the Pa- cific, take such steps as may be necessary to bring about an international treaty for the restoration of the vanishing resources of the Pacifie to their former abundance, that they may be maintained for all time as the objects of great commercial fisheries of which they are easily capable, and be it further Resolved, That this Commercial Conference rec- ommends that the governments of the countries bordering on the Pacific enter into correspondence for the purpose of establishing an jnternational commission for the scientific study of the biology, physics and chemistry of the Pacific in the inter- est of the restoration, proper utilization and con- servation of its vanishing natural resources. THE UNIVERSITY OF WYOMING AND DR. NELSON Tue trustees of the University of Wyoming have passed the following resolutions: Whereas, Dr. Aven Nelson, after five years as president of the University of Wyoming, resigned at the June meeting of the board of trustees, and Whereas, His activities as president ceased October 2, upon the arrival of his successor, Dr. Arthur G. Crane, of Edinboro, Pennsylvania, and Whereas, Dr. Nelson has served this university in various capacities from the infancy of the institution, in all of which he has succeeded to a high degree, and Whereas, His industry, his patience and his scholarship were controlling factors in. carrying the University of Wyoming through the world war and the reconstruction period thereafter to its present success. DECEMBER 15, 1922] Be it resolved, By the board of trustees of the University of Wyoming that we appreciate more fully than we can express his splendid loyalty and labors; that we extend to him our sincere wishes for a continued pleasant relationship upon his return to his former position as professor of botany; that we bespeak for him and Mrs. Nelson a long and happy life and all the joy and satisfaction which come from real service and the ‘knowledge of a duty well done. Resolved, That this expression of our good will be made a part of the permanent records of this board, and a copy thereof be transmitted to Dr. Nelson. W. C. DEMING, President, the Board of Trustees INDUSTRIAL DIVISION OF THE AMERICAN CHEMICAL SOCIETY In order that more time can be given to the presentation and discussion of papers delivered before the Industrial Division, American Chemical Society, it has been decided to ask all who plan to give papers before this division to submit completed manuscripts not later than March first to the secretary of the division. The manuscripts will then be sent to reviewers in a similar manner as contributed articles now submitted to any of the journals of the Amer- ican Chemical Society. Upon favorable recom- _mendation of the reviewers and the officers of the division, the papers -will be included in the final program of ithe division. It has been keenly felt for some time that something must be done to raise the standard of some of the papers which have been given before the division. No doubt the new method will reduce the number of papers to be pre- sented at any one meeting, but it is felt that a few genuinely good papers followed by a suf- ficient ‘time for discussion will be what most chemists desire. many papers on the program that a time limit of seven minutes was allotted with three min- utes for discussion. This time proved to be so short that a speaker could not present the paper in the best manner possible, and the period for discussion was so short that there was practically no attempt on the part of mem- bers to diseuss the subject. THE SCIENCE At Pittsburgh there were so . 681 Since the spring meeting occurs at New Haven from April 3 to 7, inclusive, it is neces- sary for members of the American Chemical Society who are planning to present papers before the industrial division to send their papers on or before March 1 to the secretary of the division.

THE UNION OF AMERICAN BIOLOGICAL SOCIETIES THE most important business before many of the societies concerned at the Christmas meet- ings is the consideration of the proposed or- ganization of the Union of American Biological Societies.1 That there is strength in union has long been believed. The practical questions before the biologists of the country are two: first, is it possikile to achieve effective union in the diver- sity of biological interests; second, is the pro- posed Union of American Biological Societies a sufficiently well thought out plan of organiza- tion to give fair promise of effectiveness? The answer to the first question would. seem to be a clear and obvious “Yes.” More di- verse groups have already shown that they can by union achieve cohesiveness and power. The unbroken record of history, from the time when Benjamin Franklin said, “We must hang to- gether or we will hang separately,” to the present, from ithe first pooling of the common interests of unlike individuals to the Standard Oil Company and the American Chemical So- ciety gives testimony to the real effectiveness and power of united effort. As to the second question, that can only be answered after a study of ‘the plan of organiza- 1 The original name was the Federation of American Biologial Societies. The word Federa- tion in the Constitution has been changed by vote of the temporary executive committee to Union because of the confusion that some have thought would be caused by the similarity of the first provisional name to that of a small group of so- cieties already organized. 682 tion as published in ScieNcE of September 29. .The plan has evolved after long discussion as a matured expression of opinion of the repre- sentatives of some twenty-five organized groups of biologists. If this plan fails it seems likely that we will wait a very long time for any im- provement to come to biology from the con- certed efforts of its scattered votaries. I. F.

Sir Havelock Charles said that, if the aspirations of the school were met, the support of the staff and students would be freely given the new arrangements. TtrouGH the president, M. Appell, the Mar- quise of Arconati-Visconti has given the sum of 100,000 franes to the French National Com- mittee to Aid Scientific Research. THE Paris correspondent of the Journal of the American Medical Association writes that French laboratories “are lacking in financial resources, and that they find it difficult to sup- ply what is indispensable in the way of instru- ments and to secure the new men needed. This state of affairs, so profoundly regrettable, was clearly brought out at a recent meeting of a group of scientists held under the auspices of the Bienvenue francaise, to which representa- tives of the lay press had been invited. Two ways are open to remedy the situation. Pro- fessor Appell, rector of the University of Paris, has announced that a national committee for the aid of scientific research has been founded. It is also planned to address an appeal to M. Poincaré, president of the council of ministers, to authorize, in connection with the centenary of Pasteur, a journée nationale in favor of our laboratories.” In the course of a field trip the past summer with a class from the Univetsity of Chicago, Dr. Adolph C. Noé, assistant professor of paleobotany, secured from Mr. C. D. Young, of Morris, Ulinois, a valuable collection of fossil plants and animals from the Mazon Creek. Mr. Young, who is master in chancery of Grundy County, presented the collection to the University of Chicago. It consists of 900 choice specimens selected from a great number which Mr. Young has been collecting through nearly forty years, and is the last great private 686 collection of Illinois fossils available. The col- lection, which represents a value of several thousand dollars and was given to the univer- sity without any conditions or reservations, will be housed in the Walker Museum of the university.

DISCUSSION AND CORRESPOND- ENCE GLACIATION IN THE CORDILLERAN REGION}! To tHE Epiror or Science: Communica- tions on the above subject by Thomas Large and Frank Leverett have appeared, respective- ly, in the September 22 and October 6 issues of Science. To these the writer wishes to add that during May and June, 1922, he found glacial drift including till with striated stones similar to that mentioned by Leverett at many other places on the Columbia Plateau west and southwest of Spokane. The writer expects to study the region further and to publish the results later on, but the information now at hand is sufficient to warrant the statement that 1 Published by permission of the Director of the U. S. Geological Survey. DECEMBER 15, 1922 during one or more comparatively early stages of the Pleistocene ice from the north advanced over the Columbia Plateau in a southwesterly direction far beyond what heretofore has been regarded as the southern limit of glaciation. The evidence at hand tends to show that the ice extended at least over large parts of Spokane, Lincoln and Adams counties, and less complete information suggests the possibility that the glaciation extended much farther. Concerning the glacial drift, which by the way is not the only evidence the region affords that land ice was formerly present, the alterna- tive ideas that it was brought to place by float- ing ice or running water have been considered and rejected. Large patches of the drift may be seen southwest of Cheney, west of Lantz, and in the neighborhoods of Winona, Lacrosse and Kahlotus, these occurrences being selected for mention at random and not because they are more typical than scores of others scattered throughout the region. The writer wishes to point out that he does not herein attempt to correlate or otherwise define the relations between the glaciation de- seribed and the glaciation already known to have covered the plateau west of the Grand Coulee or an ice stream which, as shown by recent observations, traversed the ecoulee itself. J. T. PARDEE U. S. GEOLOGICAL SURVEY EFFECTS OF COPPER WIRE ON TREES In 1918 the writer heard it stated that shade trees were being killed by driving one or two pieces of copper wire into each. To test the effects of copper wire six young trees from two to four inches in diameter were selected, and on March 21, 1919, there were driven into each tree five pieces of large copper wire 1.5 inches long. The end of each wire was left flush with the outer surface of bark. All wires were with- in six feet of the base of the tree. The trees comprised two hemlocks, two alders, one cedar, one willow. On July 3, 1922 the trees were examined and found to be perfectly healthy. In all cases they had completely healed over the wires, and their growth was equal to that of other similar SCIENCE 687 trees in the immediate vicinity. On cutting into the trees, it was found that there was very little injury to the wood, merely a brown color showing for about 1.5 inches above and below the wire, and about 0.25 inch to each side. Grorce B. Rica UNIVERSITY or WASHINGTON TANGENT LINES Oscoop and Graustein state in their Analytic Geometry, page 176: “A tangent to a conic might then be defined as the limiting position of a line having two points of intersection with the conic, when these points approach coin- cidence in a single point.” This accords with the ancient idea of a tangent as touching a conic at only one point. That idea is given in a paragraph on page 163 of my History of Mathematics, from which Professor G. A. Mil- ler quotes! part of a sentence and then criti- cizes that part. I illustrate this mode of eriti- cizing by quoting from Professor Miller’s re- view the following: “Students can usually prove a large number of theorems which they do not understand.” Serious-minded readers would deny this statement, but when they read the whole sentence and the paragraph from which this fragment is taken, they will ac- quiesce. FLortan Cagort SCIENTIFIC BOOKS i A Treatise on the Analysis of Spectra. By W. M. Hicks, Se.D., F.R.S., emeritus pro- fessor of physies in the University of Shef- field, formerly fellow of St. John’s College, Cambridge. Cambridge University Press, 1922, 231 pp. of text, 92 pp. of tables and 25 figures. The purpose of the book is twofold, to serve as an introduction and handbook and to pre- sent the mature results of the author’s extensive investigations. The treatise is based on an Adams prize essay presented in 1921. For the first purpose the appendix contains the Meggers and Peters tables for corrections to be added to the wave-lengths in air to reduce 1This Journal, October 13, page 421. 688 to vacuum, Rydberg’s values of N/(m + »)?, data for wave-lengths and wave-numbers of lines allocated to series, and the Hicks formula constants, in Chapter V in which he considers the effects of physical conditions, the various Zeeman patterns so far determined, illustrative of Preston’s law, are collected for convenient reference and also the Stark data, and a table of radiation and ionization potentials is included. Chapters II and III give a clear introduc- tion to types of series and to the series systems now recognized in the different groups of the periodic table. In the following chapter Ryd- berg’s rules are discussed in the light of the series systems now determined and of the avail- able spectroscopic data. With the exception of the constancy of N, he considers that all the values are valid; as to N he concludes that we ean not hope to determine exact values of N in the various series and elements from deter- mination of formule constants alone, that it is practically certain that the value in general is larger than Rydberg’s value and nearer Bohr’s limit and that changes in N in the different sequences should not be unexpected. A distinctive contribution by Hicks to the study of series is his modification of the Ryd- berg formula which he writes n = A — N/ (m + p + a/m)? where A is the limit, p. + a/m the “mantissa,” and N 109675 R. U. In his notation the separations from the limit in a series of lines form a “sequence” of values and a particular value is the mth “sequent.” Separation is the differ- ence in the wave-numbers of two lines, v = doublet separation, A = the difference in the mantisse of doublet sequences and is shown to be an integral multiple of the “oun.” The mantisse play an important role in the author’s development of the idea of the oun and “linkages.” He writes A = m q w? where m is an integer, gq a universal constant, and w the atomic weight, which for convenience he divides by 100. From a consideration of the doublets of Ag he finds that q is 361.78. The oun is considered to be a fundamental constituent in spectra and is written oun = 4, = %6 where 6 = 361w?. The evidence given SCIENCE [Vou. LVI, No. 1459 for the dependence of the oun on the square of the atomic weight is very strong, but the ex- istence of isotopes introduces difficulties which the author recognizes but does not succeed in disposing of completely. When a multiple of the oun is added to the limit mantissa, the modification is called dis- placement and a displaced line a “collateral.” This leads to his theory of linkages, “that in certain elements the spark spectra consist almost wholly of long sets of lines differing from one another in succession by certain spe- cial separations which can be calculated from the ordinary series limits and A, these separa- tions may be called links, and a complete set a linkage. These linkages appear to start from ordinary series lines.” The subject of linkages is too complicated for presentation in a review; it aims ‘to relate the lines which do not belong to the regular series to lines occurring in the ordinary series by a set of links. These links may occur in any order forming chains and meshes of lines. That “linkage spectra” repre- sent realities and form a category coordinate with series and ‘band spectra would seem to be a matter for further investigation. The reviewer’s impression is that the author over-estimaltes tthe accuracy of the spectro- scopic data and one wonders whether with more accurate data the evidence for linkages would be increased or lessened. Professor Hicks is convinced that links occur with much greater frequency than a chance arrangement would suggest, but considers the most conclusive evi- dence to be furnished by the large number of regularities, repetitvons, collocations of links and meshes. It is, however, somewhat sur- prising that lines in spark spectra should be related to each other by separations calculated from the limits and the A of the ordinary series inasmuch as spark spectra are charac- terized by their special types of series. Chapters VIII and IX are devoted to a dis- _ cussion of the distinguishing properties of the p and s and of the d and f sequences. For the p sequence the march of the mantisse and atomic volumes is so close that he concludes that the p sequence depends directly on a quan- tity equivalent to the volume of the atom. On DEcEMBER 15, 1922]. the other hand the d and f sequents have as mantisse multiples of the oun. The last two chapters are given to the monatomic gases and to the consideration of miscellaneous questions. This book by Professor Hicks representing extensive researches for data and extended eal- culations based on the material collected and giving the views of one who has studied the subject so long and thoroughly will prove a welcome addition to a working library. It pre- sents a general and connected view, provides a means of ready reference and suggests lines of investigation, It is well indexed and replete with references to original sources. CuHarues E. St. JoHN AMERICAN EOSINS In a recent report of this committee! it was mentioned that a number of satisfactory sam- ples of eosin had been obtained from American sources. At the time this early report was published no very definite data were at hand to show how these samples compared with sam- ples of Griibler’s eosin. At the present time, however, data have begun to accumulate giving a more satisfactory survey of the whole situa- tion and it seems time to publish them. Kosin is a compound of the phthalein series with a formula essentially as follows: a ae KO VN oO eGR eee ese |e, Ne | oN — CO.Kk There are an almost innumerable number of different eosins on the market, differing slightly in chemical composition and having quite dif- ferent properties and_ solubilities. They are usually classed in three or four groups denoted in Schultz’s Farbstofftabellen, fifth edi- tion, under the numbers 587, 588, 589 and 590. Hosin 587 is the stain best known to the staining 1Committee on Standardization of Stains: “¢Preliminary Report on American. Biological Stains,’’? Screncrz, N. 8., LVI, 156-160. SCIENCE 689 biologist. formula given above, namely the potassium salt of tetrabromfluorescein; but the monobrom and dibrom derivatives are also known, and as they sometimes occur mixed with ‘the tetrabrom compound, the composition of this dye varies somewhat. Its color varies accordingly, be- cause the more bromine atoms the bluer the shade. This dye is specified in ithe trade by such terms as eosin, yellowish eosin, eosin Y, and eosin G, water-soluble eosin, eosin W, eosin Y extra, eosin § extra. Kosin 588 and 589 are both known as alcohol- soluble eosin, being only slightly soluble in water, but differ from each other in that 588 contains a methyl group in the place of one of the potassium atoms in the above formula while 589 contains an ethyl group in this same position. Number 588 is more correctly called methyl eosin while 589 is called eosin S or primrose. ae Kosin 590 is a compound in which two of the bromine atoms have been replaced by NOo- groups. This compound, like 587, is readily soluble in water but differs from it bluish color. It is known as bluish eosin, eosin B or eosin BN. It must be understood that with such great variation in the possible composition, every manufacturer puts on the market a product slightly different from that of any other and as these compounds differ in shade each differ- It is typically the same as the in uts ent product is generally known by its own trade designation. This gives the very con- fusing list of designations applied to eosin, of which those mentioned above are merely the commoner It simplifies matters, how- ever, if it is remembered that the terms eosin, yellowish eosin or water-soluble eosin refer to 587, while alcohol-soluble eosin refers to 588 or 589 and bluish eosin to 590. No attempt was made in this work to get uniformity in the technic that was used, each collaborator being asked to use ‘the samples for any purpose and according to any technic with which he was familiar. One of the inves- tigators, in fact, reponts five different tests to which he submitted the samples. As a result, these samples have been tested in a great ones. 690 variety of ways and although at is hardly to be expected that the reports would be uniform under such conditions, it is felt, nevertheless that they have considerable value on account of the number of different methods by which the samples were tested. One of the collab- orators tested tthe samples by the simple stain- ing of bacteria; two used them for counter- staining in the Gram technic for staining bac- teria. In three cases they have been tested in blood stains, in one ease with hematoxylin, in another with methylen blue in the well-known Wright method, and in the third without com- bination with any other dye. Three of the investigators used the samples in tissue stain- ing as a counter-stain against hematoxylin. One of~the investigators, besides using the eosin in blood work and as a counterstain in the Gram technic, reports results obtained in staining cultures of Penicillium. These cul- tures after being killed and fixed were stained in mass, then mounted and examined. Lastly, another collaborator reports using the samples in two indicator media, one with brilliant green and the other with methylen blue. The variety of these methods is sufficient so that there is good reason to feel that any sam- ple which gave good results in all cases can be safely recommended. It was very clearly demonstrated that in the great variety of pur- poses for which these samples of eosin have been used, the American samples almost with- out exception are the best. Some may be slightly better than others for certain special purposes but there seems to be no reason for condemning any of them. Satisfactory samples were obtained from the following American concerns: Eimer and Amend, Harmer Laboratories Company, Heller and Merz Company, N. Y. Color and Chemical Company, Providence Chemical Company, Darwin Chemical Company, Campbell and Company, Geigy Chemical Laboratory, Cole- man and Bell Company, H. 8. Laboratories, E. Leitz, National Aniline and Chemical Com- pany Company and D. H. Pond. The chairman of the committee is ready upon request to furnish investigators with informa- tion as ‘to the apparent merits of each of these samples for particular purposes and as to how SCIENCE [Vou.

Conn, Chairman ZOOLOGICAL NOMENCLATURE In accordance with the provisions respecting the use of “plenary power” by the Interna- tional Commission on Zoological Nomenclature, to suspend the rules in cases in which the appli- cation of the rules will produce more confusion than uniformity, the secretary has the honor herewith to notify the zoological profession that a proposition by Commissioner David Starr Jordan is now before the commission to suspend the rules in the following cases and to “definitely reject the works named below from consideration under the namely: law of priority,” Gronow, 1763, Museum Ichthyologicum.

The secretary is fully persuaded that the ap- plication of the rules to the foregoing publica- tions will continue to result in greater confu- sion than uniformity and he proposes at the expiration of the proper time (one year) to recommend to the commission the adoption of Commissioner Jordan’s proposition. Zoologists interested in this proposition, pro or con, are cordially invited to present their views in writing to any member of the commission so that they can be given due con- sideration when this proposition comes to vote (approximately October 1, 1923). Views, pro or con, which reach the secretary prior to Sep- tember 1, 1923, will be manifolded and sub- mitted to the commission prior to the final vote. C. W. StILEs, Secretary to Commission SPECIAL ARTICLES THE ORGANIZATION OF THE NERVOUS MECHANISM OF RESPIRATION We have been accumulating experimental data on the nervous mcehanism of respiration for some years past, but these results have been for tthe most part presented in preliminary notes only. Cireumstances have arisen which make it seem probable that the publication of the full experimental data must be still further delayed. We wish, therefore, to present a SCIENCE 691 brief summary of our general conclusions at this time. Gad stated that the nervous mechanism of respiration extended from the facial nerve to the lumbar plexus. We must, in all probability, enlarge ‘the field to include the fifth cranial nerve. Any. statement of the organization of this mechanism must take account of all the pertinent elements found in this rather exten- sive region. The primitive nervous mechanism for the control of respiratory movements in vertebrates has its central representation in the medulla oblongata. Against Trevan and Boock’s view? of a primitive respiratory center in the region of the corpora quadrigemina we would say, (1) that we have no evidence of any cells in this region which are sensitive to carbon di- oxide in the same sense that the central cells in the medulla oblongata are sensitive to it; and (2) since the corpora quadrigemina them- selves are not primitive, it is difficult to see how such a primitive mechanism ‘could be lo- cated there. The activity of the central respiratory mech- anism in the medulla is conditioned by (1) the concentration of substances dissolved in the blood, e.g., carbon dioxide; (2) the tempera- ture of the blood flowing through the medulla; (3) the volume of blood flowing through the medulla in unit time, and (4) afferent nerve impulses from various peripheral sensory fields. All these various conditions are summed al- gebraically in the central respiratory mech- anism. This view implies an important exten- sion of our common idea of the summation of stimuli. The afferent nerve impulses arise, in higher mammals, e.g., the cat, from the lungs and the 1 Pike, F. H. and Coombs, H. C., Soc. Ea. Biol. and Med., 1917, xv, 55; Am. Journ.

The afferent paths are (1) the vagus (tenth cranial nerve) from the lungs ‘and ‘trachea, the fifth cranial from the mucous membrane of the nose, the glossopharyngeal (ninth cranial) from the pharynx and the portions of the soft palate, the phrenic? from ithe diaphragm, the sym- pathetic* from the thoracic wall, and the dorsal roots of the spimal nerves from the thoracic and abdominal muscles. The central connections of the vagus do not necessarily extend beyond the medulla oblong- ata. The central connection of the spinal tracts arising from dorsal root fibers are pri- marily with the mid-brain (region of the cor- pora quadrigemina) and only secondarily with the medulla oblongata. We have no evidence of any-itrue respira- tory mechanisms of an accessory sort in the spinal cord. The efferent root cells in the spinal cord have no special sensitiveness to car- bon dioxide. The respiratory rate lbecomes slower after division of both vagi for the reason that affer- ent impulses over the vagi, which are normally summed with the carbon: dioxide in the blood to produce an excitation of the cells of the medulla, are no longer present, and the exeita- tion of the central cells is now dependent in large part upon the carbon dioxide alone. The form of the respiratory movements changes for the same reason that the movements of a limb undergo a change in character when the afferent nerves from the limb are divided, 2.e., both ‘types of movemenits become ataxic. A further fall in the respiratory rate ensues when, in addition to, division of the vagi, there is section of the dorsal roots of the spinal nerves or ‘transection at the lower border of the midbrain because there is a still greater loss of afferent nerve impulses, and excitation of the efferent cells in the medulla oblongata be- comes almost wholly dependent upon the car- 3 Mathison, G. C., Review of Neurol. and Psychi- atry, 1912, x, 553. 4Barry, D. T., Journ. Physiol., 1912, xlv, 473. SCIENCE [Vou. LVI, No. 1459 bon dioxide of the blood. The respiratory movements also become correspondingly more abaxie. Costal movements of respiration fail afiter section of the dorsal roots alone for the reason that the efferent root cells of the intercostal nerves, which are normally excited by impulses from at least two sources—the descending res- piratory motor fibers and the dorsal roots of ithe imtercostal nerves—now receive impulses from the descending fibers only. There is no actual paralysis of the efferent root cells, since costal movements are immediately resumed when contraction of the diaphragm is prevent- ed. This indicates that von Monakow’s dia- schisis effect is due to loss of some nervous impulses normally entering into the process of excitation of a motor cell. Our idea of the manner of action of the nervous mechanism for respiration may be briefly stated as follows. Afferent impulses passing into the central mechanism in the medulla oblongata reach the efferent cells through connections which do not pass out- side of the medulla itself. The central path- ways of afferent impulses over the sympathetic fibers and the phrenics are at present unknown. Afferent impulses coming in over the dorsal roots of the spinal nerves reach ithe efferent root cells through intra-spimal connections, but the discharge of these cells is withheld until the arrival of impulses over the descending tracts in ‘the spinal cord. Impulses from these two sources are summed in the excitation of the efferent root cells. Other impulses from the dorsal root fibers pass up the spinal cord to the region of ithe corpora quadrigemina, but whether over the ventral spino-thalamie fibers? or over fibers in the spino-cerebellar tracts is uncertain. From the midbrain, these impulses are relayed to the cells of tthe respiratory cen- ter in the medulla oblongata. The excitation of these cells is dependent upon the summation of stimuli arising from (1) the concentration of carbon dioxide in the blood flowing through these cells, and (2) the nervous impulses com- ing in over the various afferent pathways. The 5 Ransom, The Anatomy of the Nervous Sys- tem, Philadelphia, 1920, p. 104. DECEMBER 15, 1922 afferent nerves thus have the double function of (1) contributing to the excitation of the cells in the respiratory center, and (2) of con- trolling the movements of the muscles arising from this excitation. While it is undoubtedly true that the respiratory center may act auto- matically under conditions which preclude the effect of afferent impulses® it is our opinion that its normal activity is not wholly auto- matic but partly reflex.

II The application of certain commercial dyes to the reductase test on milk: M1InNin F. DrESSLAR and H. A. Wxss. The decolorization of methylene blue by the reductases in milk furnishes a rapid approximate determination of its bacterial age. In order to make the test more convenient for bakers, grocers, restaurant keepers, cooking classes or housewives, who might wish to test milk claimed to be fresh on delivery, eighty-four dye- stuffs sold under trade names for household use were tested. By a series of eliminations, the most satisfactory ones were determined, eight in num- ber. They are: ‘‘Diamond Dyes’’ (wool and silk), cardinal, garnet, orange, turkey red; ‘‘ Rit’’ dyes, blue, flesh, lavender, red. The decolorization times, which vary for each, but are reasonable, and the effect on various types of milk-whole, skimmer, eream, pasteurized, boiled, malted, con- densed, evaporated, were determined. Sugges- tions for the use of the test by non-technical people are given. Data on the thickening of condensed milk: ALAN LeigHTon and CourTLanp 8. Mupcs. Use of frozen eggs in mayonnaise: S. K.

Mayonnaise made from frozen eggs held well in a warm room for thirty days. Changes in hens’ eggs stored in water glass and in lime solutions: F. C. Cook and J. B. WILSON. Strictly fresh and commercial eggs, which were preserved in water glass (1-10, 1-13 and 1-20) and saturated lime solutions. Separate jars of each were stored in the laboratory and in a cellar. At the beginning of the experiment and after various periods samples of the eggs were examined physically, bacteriologically and chem- ically. Best results were obtained by holding strictly fresh eggs in a 1-10 water glass solution at cellar temperature. Changes of considerable magnitude were found in water, ash and nitrogen contents of both whites and yolks. Bacteria were not found to be a factor in deterioration. Am- monia nitrogen and acidity of fat proved to be the best indices of decomposition. Manganese, aluminium and iron ratio as related to soil toxicity: R. H. Carr and P. H. Brewer. Much emphasis has been given in the past to the isolation of organic toxins which were thought to be the cause of soil toxicity, while in more recent times the trend of investigation has been turned more specifically to soil acidity as the reason for poor crop yield. Investigations which have been conducted on a large variety of soils using the potassium thiocyanate method for soil acidity and toxicity, described hy one of the writers, indi- cates that the cause of infertility of many soils, supplied with sufficient plant food, is due to the presence of soluble manganese compounds in some eases, to aluminum compounds in other instances and sometimes to a combination of the two. The toxicity of soluble iron is not so apparent, as it is usually associated with a considerable quantity of soluble aluminum in an acid soil. The potas- sium thiocyanate method has been found helpful in this study, because of the color changes taking place when these elements are present in the soil in easily soluble form. If the soil is more acid than p,, 5.5 a red color of ferric thiocyanate is produced in the presence of soluble ferric iron and if this soil solution containing manganese is made slightly more basic, a green color will de- velop in the liquor. The depth of the color will be proportional to the amount of manganese in the soil solution. This color begins to form when the soil contains about 0.008 per cent. of soluble manganese. The green color will be found asso- ciated with nonproductive acid soils, and since it is shown that manganese does not precipitate as a hydroxide until a p,, of about 7.9 is reached, 694 a ‘large amount of limestone (8 to 10 tons in addition to that required to remove the red color) will be required. In some instances the cost of this large amount may be prohibitive. The effect of selenium compounds wpon the growth and germination of plants: Victor E. Leyine. The findings of Gassmann (zs. Physiol- Chem., 1917, 100, 209) that selenium is a con- stituent of plants has led to the inquiry as to the effect of selenium compounds upon germination and growth. White lupine and timothy seedlings were used in the experiments. Concentrations of 0.001 per cent. to 0.0001 per cent. show no injuri- ous effect; in some experiments these concentra- tions favor growth. Concentrations of 0.01 per cent. and over are exceedingly inimical to ger- mination and to growth. The compounds may be arranged as follows in the order of diminishing toxieity: selenious acid, selenic acid, sodium selenite, sodium selenate and potassium seleno- eyanate. This order agrees well with that ob- tained with animal experiments testing the rela- tive toxicity of these compounds. It is evident from the results obtained that selenium can not replace sulfur in the nutrition of plants. The determination of nitric nitrogen in the soil solution: WaLTrrR THoMAS. The determina- tion of nitric nitrogen is the béte noir of the soils chemist. Inasmuch as the phenoldisulfonie acid method is the one that is the simplest and most rapid, and therefore more generally used by soil chemists than any other, the author has carried out some experiments on the effect of various flocculating and clarifying agents under carefully controlled conditions by this method and com- pared the results with the Devarda reduction method, which is the only one that has escaped serious criticism. The results obtained by dif- ferent investigators have been very conflicting, but the results of the present investigation indi- cate that: (1) The use of either potash alum or alumina cream (even if neutral) results in large losses of NOg; (2) CaO if freshly ignited is the most satisfactory floeculating and clarifying agent; (3) The Devarda alloy method gives ex- cellent results on the soil solution, but is not ap- plicable to rapid routine work.

Possibilities in the use and preparation of con- centrated fertilizers: Wiuuiam H. Ross. The Haber and other processes for fixing nitrogen and the volatilization method of preparing phos- phoric acid all yield materials, directly or by combination, of different composition and higher concentration than those ordinarily used in the manufacture of fertilizers. Some of these mate- rials, as ammonium phosphate, have chemical and physical properties which make them admirably suited for mixing with ordinary fertilizer mate- rials, or for making mixed fertilizers of higher concentration than any now in use. Others, as ammonium nitrate, can not be satisfactorily used in present fertilizer mixtures unless means can be devised for eliminating or neutralizing prop- erties which interfere with their use in this way. The work of the Bureau of Soils on concentrated fertilizers and fertilizer materials was therefore undertaken not with a view to replacing the or- dinary fertilizer materials, nor of providing high quality fertilizers which would command higher prices per unit, but rather with the double pur- pose of devising means of utilizing new sources of fertilizer materials and of decreasing the cost of handling and transporting fertilizers by increasing the concentration of mixtures which Tequire shipment to a distance. The advantages and disadvantages of low-grade fertilizer mix- tures are discussed and a review given of progress made in the preparation of concentrated fertilizer materials. Recent investigations on the oxidation of sulfur by micro-organisms: J. G. LipMANn. There has been isolated at the New Jersey Agricultural Experiment Station a new sulfur-oxidizing organ- ism which has been named Thiobacillus thioxidans. This organism grows readily in purely inorganic media containing, aside from the usual mineral salts, elementary sulfur. It derives its energy from the oxidation of sulfur and obtains its car- bon from carbon dioxide. It will grow readily in a medium having a hydrogen-ion concentration of 4.0 to 5.0 and will continue to multiply when the hydrogen-ion concentration exponent is below 1.0. The sulfur is oxidized by this organism to sulfuric acid. The acid so produced may be utilized for a variety of purposes. Mixtures of mineral phosphates and sulfur, properly inocu- lated with Thiobacillus thioxidans, will be con- verted into acid phosphate. Inoculated sulfur added to the soil will inerease its acidity to a point where certain objectionable fungi, like those DrcEeMBER 15, 1922] producing scab of potatoes and scurf of sweet potatoes, may be largely if not entirely sup- pressed. The transformation of sodium car- bonate, present in excessive amounts in so-called black alkali soils, into sodium sulfate may be similarly accomplished. The direct use of inocu- lated sulfur for the purpose of supplying sulfates where these may be, present in inadequate amounts, or the use of the same material for the production of potassium sulfate from greensand marl is indicated. The elimination of soil-infest- ing insects, or nematodes and of undesirable vege- tation may also be accomplished by means of sulfur inoculated with cultures of Thiobacillus thiowidans. Trend of modern fertilizer plant construction: Perer 8. Gincurist. This paper will deal with the construction features of up-to-date fertilizer plants, including types of buildings, materials for build- ing construction, equipment for plants and the relation of equipment to the building. Especial attention will be given to the design of plants with the necessary equipment for the economical handling of materials, silos or storage bins for storing phosphate rock, air separation for ground rock, the development of mechanical dens for making ecid phosphate and economical methods of manipulating and bagging finished goods.

SO4 is used to absorb NOs, and part of the NO if the latter is present with NO . The total nitrogen and the nitrous nitrogen in the acid are after- ward determined, and from them the NO» and NO absorbed are calculated. A definite volume of std. permanganate soln., acidified with H3P04, is used to absorb the rest of the NO, and after- ward the excess permanganate is determined. The total NO originally present is the sum of that absorbed in the HpSO, and in the permanganate soln. The method was tried on known quantities of the gases, and was found satisfactory. The action of hydrogen peroxide on photo- graphic gelatino-silver halide emulsions: S. E. SHEPPARD and E. P. Wicurman. A detailed study of the action of hydrogen peroxide on pho- tographic plates has been made with the idea of obtaining more complete data on the subject in order to compare the action with that of light in the formation of latent images. Both the inten- sity (concentration) and time factors were consid- ered as well as development conditions. As a side problem it was found necessary to consider also the effect of concentration of the acid (or alkali) content of the hydrogen peroxide. The effects are in many ways quite similar to the action of light. Other conclusions can not be drawn until further work has been completed. We have proposed the tentative hypothesis that silver nuclei in the silver- halide grains serve as catalytic agents for the decomposition of hydrogen peroxide which is chemi-luminescent. Reactions at boundaries of phases; the problem of promoter action and the theory of the latent photographic image: HucH S. Taytor. From a literature study and from investigations it has been established that the boundaries of two phases constitute a most reactive portion of a heterogeneous system. Evidence is available to show that a number of cases of promoter action ean be attributed to enhanced reactivity of mixed catalysts at interfaces between the components of the catalyst mixture. The analogy between the development of the latent photographic image and the reduction of metallic oxides by various reducing gases at low temperatures can be estab- lished. Studies of the latter are very suggestive as to the necessary extent of nuclei production precedent to the production of a developed image in the individual grain of the photographic emul- sion.

The influence of variation of the catalyzing of acid and of its concentration, of added neutral salts and of their concentration, of temperature and of the solvent, have been made the object of investigation. It has been shown that it is prob- ably the non-hydrated hydrogen ion which is the active catalytic agent. The remarkable results which this leads to, when ether is used as solvent, have been outlined and experimentally verified. The hydrogen ion concentration of buffer solu- tions at elevated temperatures: Ropert E. Wui- son. Despite its importance from a number of aspects, there is practically no data in the litera- ture as to the hydrogen ion content of the various recognized ‘‘buffer’’ solutions at temperatures above 40° Centigrade. Since the Py Of neutral water and of ordinary solutions of alkalies drops off markedly with increasing temperature, on ac- count of the increased donization constant of water, it was especially desired to determine how the alkaline buffer solutions behaved in this respect. Measurements have been made on vari- ous borate, phosphate and phthalate solutions and indieate that the change in p,, between 30° to 90° (ealeulated ion the assumption that the Dey of 0.1 N HCl is constant) is very small, compared with that of ordinary alkaline solutions. This is, of course, due to the fact that all owe their buffer action to the ionization of acid salts of some polyvalent acid. A phosphate buffer solution has been prepared which is acid at 30° and alkaline at 90°, although its p,, remains constant. Most indicators behave much like the buffer solutions, and hence a given color may ‘indicate acidity at low temperatures and alkalinity at higher tem- peratures. The paper presents the results in graphical form. Tracks of alpha particles in gases: B. W. RYAN and W: D. Harkins. The ferrocyanide test for zine: R. D. Muu and A. L. STaLLBAUMER. Potassium ferrocyanide precipitates a white zine ferrocyanide which, when treated with bromine water, turns a ehar- acteristic yellow color. No systematic work has been done to determine the best conditions for the test or to compare its sensitiveness with that of the hydrogen sulfide test. Such work has been done by the authors and leads to the following conclusions: (1) K4Fe(Cn)¢g test for zine is ten times as delicate as the HS test. 0.1 mg. of zine ion in 50 ee. of solution can be detected, 728 1.0 mg. is about the limit for the sulfide method. (2) The test should be carried out in a solution about one half normal with acetic acid and should contain ammonium salts. Warming to 60 aids flocculation. (3) The ferrocyanides of the alka- line earth metals are too soluble to interfere, other metal ions must be removed. (4) The yellow color with bromine water is also given by cad- mium ferrocyanide. Qualitative analysis without hydrogen sulfide: R. D. Muuiinix. G. Almkvist has proposed a method without the use of H»oS, but NaoS fol- lowed by H.SO4. (Zeit. anor. Chem., 103, 221- 242, 1918). I have used for the past two years with qualitative classes a method in which, after the removal of the silver group by HCl, a mix- ture of NaOH, Na,CO3 and bromine water pre- cipitates a group of hydroxides and carbonates, which are then further separated. The As, Sb, Sn, Pb traces, An, Al and Cr are in the filtrate. This is divided by HCl followed by NH,OH, and zine tested for in the presence of chromate and arsenate by the patassium ferrocyanide method. This is a preliminary communication and will be followed by more detailed work on the group analyses and end tests. DIVISION OF SUGAR CHEMISTRY S. J. Osborn, chairman Frederick Bates, secretary Detection of sugar in condensed waters by means of cresol: G. E. Stevens. Fifteen ml. of eresol (U. S. P. Merck) is dissolved in a eastile soap solution (6 gms. soap in 100 ¢.c. of distilled water). The mixture is warmed until a complete solution is obtained. This solution can be made up in litre quantities in the above proportions without deterioration. Approximately one inch of water to be examined is placed in a 6 inch by 5% inch test tube and five to ten drops of the eresol solution is added and then thoroughly mixed. . Cool if the water is hot and then add concentrated sulfuric acid from a dispensing burette, holding the tube in ian inclined position so that the acid will run down to the bottom and form a separate layer, and continue to add the acid until the acid layer is %4 inch deep. The tube is then rolled between the palms of the hands and if sugar is present a reddish black to pink color ring will develop, the color depending upon the concentration of sugar in solution. y/4y? + 4yz i. e., the concentration of the erystalloidal ions inside the protein solution 2y + ¢ is always greater than the concentration of the erystal- loidal ions 2% outside, when zis not 0 or ©. If we substitute for the term 2y + 2 — 2a of the Donnan correction the identical term V ty? + 4yz +22 — \/4y? + 4yz we can visualize why the osmotic pressure is a why it minimum at the isoelectric point, increases with the addition of little acid, reach- ing a maximum, and why it diminishes again with the addition of more acid. At the isoelectrie point no protein is ionized and z being zero, the whole term v/4y2 + 4yz 22 — v/ ty? + 4yz becomes zero. Hence at the isoelectric point the observed osmotic pressure is purely ‘that due to the protein, which is very low on ac- count of the high molecular weight of gelatin. 738 When little acid, e. g., HCl, is added to the solution of isoelectric gelatin, gelatin chloride is formed and some free acid remains, due to hydrolytic dissociation. Hence both z (the concentration of Cl ions in combination with protein) and y (the Cl ions of the free HCl existing through hydrolysis) imerease, but z increases at first more rapidly than y and hence the excess of concentration of ions inside over that of ions outside inereases until the greater part of protein is transformed tmto protein chloride, when the excess of erystalloidal ions inside over those outside reaches a maximum. From then on z increases comparatively little while y increases considerably with further addition of acid, so that z becomes negligible in comparison with y. This explains why the Donnan correction becomes zero again when enough acid is added, and why the observed osmotic pressure becomes as low again as at the isoelectrie point. In the same way it can be shown why the addition of salt has only a depressing effect on the osmotic pressure. Let us assume that there is inside the bag a gelatin chloride solution of Py 3.0 to which NaCl is added. z (the concen- tration of Cl ions in combination with ‘the gelatin) will not increase with the addition of salt, while y (the concentration of the Cl ions not in combination with gelatin) will increase. Hence with the increase in the concentration of the salt the value of y/ fy? 4yz 22 — y/4y? + 4yz will become smaller, finally approaching zero. geen ] T 425 > 7 Ly ast 400 |—}- a ee 375 a A , | Laval, ?

LVI, No. 1461 When another salt than a chloride, e. g., NaNOs, is added to a solution of gelatin chlo- ride, we may assume that the gelatin in solu- tion is gelatin nitrate. Fig. 3 gives a comparison of the curves for the observed osmotic pressure and for the Donnan correction. Both curves rise in a par- allel way from the isoelectric point reaching a maximum which is 450 mm. H2O pressure in the case of the observed osmotic pressure and slightly lower in the case of the Donnan cor- rection. The observed osmotic pressure should be higher than the Donnan correction by the osmotic pressure due to the protein solution itself. A difference exists in the values between py 4.6 and 3.2 but disappears later, and this difference is in all probability the ex- pression of value a, 7. e., the osmotic pressure due to ‘the protein itself. The disappearance of this difference at p,;,; below 3.2 is probably due to the fact that an error of one unit in the second decimal of the p,;,; causes a considerable error in the calculations of z which increases when the p,, is too low. Fig. 3 shows that when we correct the ob- served osmotic pressure for the Donnan effect it follows that the influence of the p,, of the acid on the osmotie pressure is entirely or prac- tically entirely due to the excess of the con- centration of erystalloidal ions inside the mem- brane over that outside and that this excess is caused by the Donnan equilibrium. The osmotic pressure of the protein itself is either not altered at all by the addition of acid or if it is altered ‘the effect is too small to be no- ticeable. There is then nothing left for the “dispersion theory” or for any other of the colloidal speculations to explain. These re- sults were confirmed for crystalline egg albu- min and casein by the writer and for edestin by Hitcheock. We now understand why only the valency and not the nature of the ion plays - a role in the osmotic pressure of protein solu- tions. The equilibrium equation is one of the second degree when the ion with which the pro- tein is in combination is monovalent while it is of the third degree when the ion is divalent. Only the valency of the ion and not its nature enters into the Donnan equation. We can therefore summarize these results by DECEMBER 29, 1922] stating that the so-called colloidal behavior of protein solutions, as far as osmotic pressure is concerned, is merely the result of an equilib- rium condition of classical chemistry which re- sults in an excess of the concentration of erystalloidal ions inside the protein solution over that of an outside aqueous solution, when the two solutions are separated by a membrane which is permeable to crystalloidal ions but impermeable to protein ions. The colloidal behavior of proteins depends therefore entirely on the relative non-diffusibility of protein ions through membranes which are easily permeable to erystalloidal ions. Since the majority of membranes in plants and animals belong to this dlass, it can easily be surmised how great a role the proteins must play in the regulation of osmotic pressure in the body. VI It remains to show briefly why swelling and viscosity of protein solutions are affected in a similar way by electrolytes as is the osmotic pressure. The answer is that we are dealing in both cases with the same fundamental prop- erty, namely, osmotic pressure. In 1910 Procter made the ingenious sugges- tion that the swelling of gelatin might be an osmotic phenomenon and in subsequent papers he and J. A. Wilson put this theory on a quan- titative basis by deriving it from the Donnan equilibrium. They showed that the swelling of a solid gel of gelatin in hydrochlorie acid can be explained quantitatively on the ‘basis of the Donnan equilibrium on the assumption that there exists an excess of concentration of erystalloidal ions inside (in this case H and Cl) over the concentration of the same ions outside, and that the excess of osmotic pressure inside the gel over that outside due to this Donnan effect accounts for that share of the swelling which is caused by the influence of the acid. The agreement of their caleulated values with the observed values’ is excellent. The writer is inclined to consider Procter’s theory of swell- ing and the proof of this theory by Procter and J. A. Wilson as the most brilliant con- tribution to the theory of collaidal behavior next in importance only to Donnan’s theory of SCIENCE 739 membrane equilibria. There was only one de- tail left by these authors, namely, to prove the existence of membrane potentials ‘between the gel and the surrounding aqueous solution at equilibrium. The writer was able to fill this gap and to show that the observed P.D. between gel and surrounding aqueous solution can be calculated with a fair degree of accuracy from the value py inside minus p,;, outside with the aid of Nernst’s logarithmic formula. VII It may seem strange that the influence of electrolytes on the viscosity of certain protein solutions should be explained in the same way, but this seems to be the case. According to Einstein’s formula, the viscosity of an aqueous protein solution is a linear function of the relative volume of the solute occupied in the solution, as expressed in the formula 4 = 1 (1 + 2.59) where 7 is the viscosity of the solution, y, that of pure water, and 9% the proportion of the volume of the solute to that of the solution. If, therefore, the addition of little acid to a 1 per cent. solution of isoelectric gelatin inereases the viscosity of the solution until a maximum is reached and if the addition of more acid depresses the viscosity again, it fol- lows that the addition of acid changes the rela- tive volume occupied by the gelatin in water. This is only possible by water being absorbed by the protein and the question is how to ac- count for this absorption of water by the pro- tein under the influence of acid. Pauli assumed that the ionized protein surrounds itself with a jacket of water which is lacking in the non- ionized protein. If this were true, all the pro- teins and amino-acids should show such an influence of acid on the viscosity of their solu- tions. The writer found that no such influence exists in the case of amino-acids and at least one protein, namely, crystalline egg albumin; if Pauli’s assumption were correct, there is no reason why crystalline egg albumin should not show the same influence of acid on viscosity which is found in the case of gelatin. The dif- ference between gelatin and crystalline egg albumin is that the former sets to a solid gel 740 if the temperature is not too high while the latter does not. The formation of a continuous gel in the gelatin solution is preceded by the formation of submicroscopic aggregates which occlude water and which are capable of swell- ing and these aggregates or precursors of the continuous gel increase in size and number on standing. To test this idea the writer made experiments of powdered gelatin in water and found that such suspen- sions of powdered gelatin had a much higher wiscosity than a freshly prepared solution of This was to be expected if the influ- ence of acid on the viscosity of proteins is due with suspensions gelatin. to the swelling of submicroscopie particles of gel. It harmonizes with this fact that the vis- cosity of solutions of crystalline egg albumin is of a low order of magnitude, which was to be expected if solutions of erystalline egg albumin contain few or no micelle. It was found, moreover, that the viscosity of suspen- sions of powdered gelatin increased under the influence of acid or alkali in the same way as did the swelling of jellies or the osmotic pres- sure of protein solutions. The viscosities were measured at 20° C. When the suspension of powdered gelatin was melted, it was found upon rapid cooling to 20° C. that the viscosity was considerably lower and that the influence of acid had almost disappeared. By these and a number of similar experiments it was pos- sible to prove that the similarity between the influence of electrolytes on the viscosity of gelatin solution and the influence of electro- lytes on osmotic pressure is due to the fact that the influence on viscosity in such cases is in reality an influence on the swelling of sub- microscopic protein particles. This proof was made complete by showing that there exists a Donnan equilibrium between powdered parti- cles of gelatin and a surrounding weak gelatin solution. VIII It may not be amiss to illustrate by way of an example why it is that the neglect of measuring the hydrogen ion concentration of protein solu- tions necessarily leads into errors. In a paper published in 1921 by Kuhn,’ it was intended to 3 Kuhn, A.: Kolloidchem. Beihefte, 1921, xiv, 147. SCIENCE [Vou. LVI, No. 1461 show that different acids of the same valency have different effects on the swelling of gelatin. In order to furnish such a proof it is necessary to start with dsoelectric gelatin and to compare the effect of different acids on the swelling of this isoelectric gelatin at the same hydrogen ion concentration of the gel, since only in that case have the gels the same concentration of gelatin ions. Instead of starting with isoelectric gelatin — or gelatin of a measured PP,» Kuhn failed to measure the p,, of his gelatin, though it makes quite a difference whether acid is added to igso- electrie gelatin or to gelatin at another Py: Purther, instead of measuring the Py of the gel with the hydrogen electrode, Kuhn ecaleulated the hydrogen ion concentrations from Kohlrausch’s. tables as if acid had been added to water free from gelatin and as if the presence of the protein did not alter the hydrogen ion concentration. Our titration curves, however, show that when acid is. added to isoelectric gelatin the hydrogen ion con- centration is less than when acid is added to water free from protein. And finally, on aceount of the Donnan equilibrium the p,, inside and outside the gel are entirely different; yet no mention is made of the Donnan equilibrium in the paper referred to. The hydrogen ion concentrations of protein solutions which were considered as equal by Kuhn were on account of all these errors en- tirely different, and it is quite natural that Kuhn came to the conclusion that different monobasic acids have different effects on swelling, since it would have been a miracle if with his faulty methods he had ever compared two acids of the same p,,, The same criticism applies to all the older experiments on the influence of electrolytes on swelling in which the authors reached the con- clusions that different anions of the same valency have different effects on swelling (Hofmeister series). In all these experiments the authors failed to measure the p,, of their gels and errone- ously attributed effects due to differences of the Py of the gels to the difference in the nature of the anion. Ix We therefore come to the conclusion that the chemistry of proteins does not differ from the chemistry of crystalloids, and that proteins combine stoichiometrically with acids and alka- lies forming protein salts which dissociate elec- trolytically. The enormously large protein ions and molecules can not diffuse freely through gels or many membranes which are easily permeable to small erystalloidal ions. DECEMBER 29, 1922] This fact leads, under proper conditions, to an unequal distribution of the diffusible erystal- loidal ions between a protein solution and an outside aqueous solution; or between a protein gel and an aqueous solution. In this distribu- tion the total concentration of erystalloidal ions is always greater inside the protein solution or inside a gel than in the surrounding aqueous solution. This is the eause of the colloidal be- havior of protein solutions and protein gels. Measurements of membrane potentials have shown that this excess of the concentration of erystalloidal ions inside over the concentration of the erystalloidal ions outside the protein solution or the gel, and consequently all the effects of electrolytes on osmotic pressure, swelling and viscosity of proteins, can ‘be eal- culated with a satisfactory degree of accuracy from Donnan’s equilibrium equation, which is not an empirical but a rationalistic mathe- matical formula. We can therefore state that it is possible to explain the colloidal behavior of proteins quantitatively on the basis of a rationalistic mathematical formula. What ap- peared at first as a new chemistry, the so-called colloid chemistry, now seems to have been only an overlooked equilibrium condition of classical chemistry; at least as far as the proteins are concerned. The oversight was due to two facts, first, to the failure of colloid chemists to measure the hydrogen ion concentration of their solutions, which happens to ‘be the chief variable in the case, and second, to their negleet of measuring and taking into consideration the membrane potentials of protein solutions and protein gels, which furnish the proof that the theory of membrane equilibria must be used to explain the colloidal behavior of proteins. Jacques Lozrs THE ROCKEFELLER INSTITUTE For MEpicAL RESEARCH, New York THE AWARD OF THE HENRY DRAPER MEDAL Tue Henry Draper medal for 1921, awarded by the National Academy of Sciences to Pro- fessor Henry Norris Russell, professor of as- tronomy at Princeton University, was pre- SCIENCE 741 sented to him by Dr. C. G.. Abbot, assistant director of the Smithsonian Institution at the annual dinner in New York City on November 15. Dr. Abbot spoke as follows: The brilliant and penetrating insight of Dr. Henry Norris Russell, of Princeton University, has led dn recent years to a development of as- tronomy so rapid that it has proved thus far impossible to publish really up-to-date text-books on the subject. Before the manuscript of a text on astronomy can be prepared, much less carried through ‘the press, new knowledge renders the treatment. sbale. Dr. Russell has made basic contributions to the great problem of stellar evolution. He saw clearly that the brightness of a star as we see it depends on several factors. First, there is the intrinsic brightness of the star as a source of light. What the tallow candle is to the electric are, so one star may be to another in the bright- ness of its shining surface. Secondly, the total amount of ght which a star sends out depends upon its diameter. Quite recently it has been shown, for instance, that the star Alpha Orionis is three hundred times the diameter of the sun, and accordingly its cross-sectional area is ninety thousand times the cross-sectional area of the sun. Hence, if they were of equal surface brighitness, the star Alpha Orionis would send out ninety thousand times as much light as the sun. In tthe third place, the brightness of the star depends upon its distance from the earth and falls off as the square of that distance. Thus, the sun, which is so near that it takes light eight minutes to come from it, being about two hundred thousand times as near as ‘the next nearest star which takes light three or four years to reach the earth will appear forty million times brighter on that ac- count. With these conditions in mind, Dr. Russell, in collaboration with Dr. Hinks, of England, began by the application of a new photographic method of determining the distance of stars, and in 1910 published the results showing the approximate distance of 55 stars. With this and other such information which had been laboriously acquired by others, he was able to show that the red stars evidently must fall into ttwo classes: one class. sending out very much more ght itthan our sun, and another sending out very much less, and that between these ‘two very widely separated extremes there are no red stars intervening. Going on, he applied the, until then little used, knowledge of the eclipsing variable stars with the 742 most penetrating theoretical ability. For many years measurements have been going on at Har- vard Observatory and elsewhere on the march of brightness of such stars as Algol, in which we see a pair of objects which im their rotation about their common center of gravity periodically eclipse each other. Dr. Russell showed how the elements of the eclipse, comprising the observed brightness and the corresponding jtimes, could be treated in ‘order to give probable relative values of the densities of stars in the different eclipsing systems, and with his pupil and collaborator, Dr. Shapley, who applied Russell’s methods, the re- sults for 87 stars were obtained and published in 1913. In the meanwhile, many additional stars had been measured for distance from tthe earth, and by combining ‘the information then available, Russell showed in 1913 that the stars may be divided into two extraordinary sequences which, following Hertzsprung, he called the ‘‘ giants and dwarfs.’’ In short, the ‘‘giants’’ beginning with the red and going on to the yellow, white and blue, form a series of substantially equal output of light far in excess of that which is expended by our sun, and their densities, beginning with the red stars which are so rare that (the maiterial of which they are composed is more to be compared to a fairly high vacuum than to ordinary gaseous, liquid or solid densities, increase as the sequence goes on until with the blue stars the density has become much more considerable. From this point tthe descending series of the dwarfs begins, and the density reaches in our yellow sun about one and one half times that of water and from this goes on to the very red and small stars whose density is as great or greater than that of the earth itself. So regular is the light progress of this fascinat- img series of dwarf stars thait if one merely ob- serves the type of spectrum which one of its mem- bers possesses he can tell with reasonable limits the total amount of light which is emitted and therefore, in connection with its apparent bright- ness, can determine tthe probable distance away from the earth in space. On the other hand, if a cluster, such, for in- stance, as the great cluster in Hercules which are known to be stars of substanitially equal distance from the earth, contains a group of stars of ap- proximately equal brightness ranging through all the types of spectrum from jthe blue to the red, it follows that (they are all giants and therefore emitting light of a roughly known quantity thou- sands of times in excess of that emitted by the sun, and from this the distance of the cluster SCIENCE [Vou. LVI, No. 1461 ean be fairly well estimated. Such considerations have been pursued by Dr. Shapley in regard to a great many of tthe clusters of stars, and have led him to assign distances in the stellar system some tenfold in excess of those which have been gen- erally assumed before. Professor Russell, taking as his text the frescoes on the walls of the banquet hail which, being known as tthe “College Room,” was dec- orated exclusively with scenes of college sport, replied as follows: Team work wins in science as well as in games. But there is this important difference, that scien- tifie team work is free cooperation; there is no coaching and no central control. If I have done anything to deserve this medal, it is because of the many men who have con- tributed to these investigations. I was particu- larly indebted to Professor Pickering of Harvard for the encouragement that he gave to a young and unknown instructor in his science. When I talked to him about my proposed work on stellar parallaxes, he volunteered his aid and provided me with observations of the magnitudes and spectra of 300 stars, which gave me the first evi- dence of the existence of giant and dwarf stars. Robert Ball says that ‘‘astronomy consists in sitting up all night and doing arithmetic all day.’’ Some men like the one thing better than the other. My part has been largely doing arithmetic. But this would not have amounted to anything without the men who were willing to sit up ail night. Here, again, is scientific team work. At Princeton we are working on double stars. If you can guess how massive a star is, you can calculate how far away it is. If you can guess at the mass of a double star you can caleulate iits distance. Now double stars—at least, those with spectra of ithe same sort—are remarkably alike in mass, so tthat the guess that those which we have not yet investigated are similar to those which we know about is likely to be a very good guess. In this way we have nearly finished caleu- lating the distances of about 1,600 double stars. To calibrate our formule, we use parallaxes de- termined in other ways, which have been gen- erously sent us (published and unpublished ma- terial alike) by Drs. Adams and Schlesinger. All the investigators of stellar distances are now playing on the same team. Not only must astronomers cooperate in re- search, but they must have the aid of the phys- icists and chemists. To know more about the stars we must know more about atoms. In fact, we would not know anything about ithe stars, even DECEMBER 29, 1922) their existence, if it were not for the atoms, which send us infiormaition by means of light. As we now know, each particular kind of light comes from one particular atom behaving in a particular way, each line in the spectrum is due to a special kind of atomic behavior. As seen with the spectrascope, the white or hotitest stars seem to be made of permanent gases, and the red and cooler stars to consist of metallic vapors. The difference in the character of the stars is probably not due so much to differences in constitution as jto tthe character of the radia- tion given off by tthe atoms. If an electron is knocked off by an atom we get a new set of spec- tral lines. If another electron is knocked off, we may get an ultra violet spectrum, which can not be seen or even photographed, since the air is opaque to such short wave lengths. Such gases as oxygen, nitrogen and helium are hard to ex- cite, so they do nat show at low temperatures. But in the hot stars they get stirred up and be- come visible. In this case the metals are so knocked to pieces that they do not make them- selves visible at all. All the stars may have sim- ilar composition, but, since the physical condi- tions are different, different elements reveal their presence in the spectra. The relative degree of ionization of different elements (which determines the appearance of the spectra) depends on an equilibrium under the law of mass action. I had always supposed that this law was the exclusive property of the chemist; but now it appears to be of fundamental importance in agtro-physics. We need the chemist on our team, and we may help in their game too. By comparing ithe spectroscopic behavior of their lines in the sun, sun-spots and stars, it appears that the ionization potentials of all the elements in the periodic table between calcium and nickel are between 6 and 9 volts, increasing steadily along the series. So here astronomy gives infor- mation about properties of atoms, which have not as yet been measured in our laborajtories, owing to practical difficulties. There is no limit in sight to the possibilities of team work such as this. APPEAL ON BEHALF OF THE LEAGUE OF NATIONS FOR AID TO AUSTRIAN INTELLECTUAL WORKERS No greater danger can threaten a civilization than the successive destruction of its homes of learning. It is beyond dispute that the war SCIENCE 743 and its economic consequences have brought intellectual life in one entire region of Europe into an extremely precarious position. The machinery of intellectual life has been seriously impaired in almost all those nations of eastern Europe, to say nothing of Russia, which ex- tend from the Baltie to the Algean. One of them—Austria—is suffering from economic dis- tress to 'a degree which threatens soon to bring all intellectual work to a standstill in the winter of 1922-1923. The truth of this statement is demonstrated by the report which we attach to this letter. Since the report was drawn up, the situation has been greatly aggravated, and its conse- quences are: (1) intellectual isolation; (2) a complete lack of all the appliances which are indispensable for intellectual work; (3) the formation of an intellectual proletariat, less favorably situated than the working-class pro- letariat—for muscle commands better wages than brain; (4) diminishing numbers of stu- dents and a dearth of recruits of the cultured classes for the liberal professions and for the teaching staffs. The committee on intellectual cooperation, constituted by the League of Nations, decided, at its first meeting on August 1, 1922, “ex- pressly to call the attention of the Council of the League of Nations to the desperate situa- tion of intellectual life in certain European countries and the urgent need of intervention.” These words had special reference to the case of Austria. At its meeting of October 4, the Council of the League of Nations requested the committee to launch an urgent appeal to universities, academies and learned 'societies in all countries in aid of Austrian intellectual workers and intellectual life in Austria. We have accord- ingly the honor, in the present Jetter, to invite you to organize measures of relief as soon as possible, with the object of saving one of the most cultured countries in Europe—a country which formerly possessed one of the chief centers of European civilization—from the fate of seeing its higher education and learning disappear from sheer want. We leave it to your judgment to organize 744 such relief measures as you may deem most practical and to employ such methods as you may consider most efficacious; we are prepared to supply you, through our secretariat, with any information or explanations which you may require. We merely beg to draw your attention to the following points: As a result of the depreciation in the Aus- trian exchange, quite insignificant sums, if con- verted into crowns, amount to very. consider- able figures. For instanee, we have pointed out in the attached report that, with the aid of 1,000 Swiss franes, the Academy of Science in Vienna could resume its publications, and that asum of 500 Swiss franes would enable almost any of the great scientific associations—such as the Anthropological Society or the Society for Modern Philology—to recommence their work. We earnestly invite the universities, acade- mies and learned societies of the whole world to send their publications to the Austrian uni- versities, academies and learned societies, or to organize systems of exchange with them. We urge them to conclude with the Amba (the Austrian “office fior providing books and instruments”) agreements for cooperation sim- ilar to that established with England. Such agreements would provide an excellent basis for the organization of intellectual relief and might be extended, with suitable adaptations, to other countries whose needs are similar to those of Austria. As regards the supply of purely material requirements (such as clothing, boots, articles of primary necessity, etc.) it is suggested that agreements should be concluded with the Zegam (the “Central Purchase Organization for Asso- ciations of Intellectual Workers”). We further invite universities, academies and learned societies to organize the exchange of professors and lecturers with similar estab- lishments in Austria, and we suggest that men of science should either visit Austria them- selves or endeavor by means of personal inter- course to break down the wall of intellectual isolation with which that unfortunate country is surrounded. In order to relieve the unhappy condition of Austrian professors, men of science, writers SCIENCE ‘be helping [ Vou. LVI, No. 1461 and artists, who are suffering increasingly from under-feeding, we would urge you to assist them and their families to spend their holidays abroad. It might even be possible—and no form of assistance could be more useful or more ur- gently desirable—to place certain immediately available funds or foundations at the disposal of Austrian men of science and students in order to enable them to continue their re- searches and studies. The aim of these suggestions, which are put forward at the beginning of a winter which may well prove decisive for the fate of Aus- tria, is to encourage to the utmost the organ- ization of relief measures from as wide a field and in as uniform a manner as possible. Much ean be accomplished with small means. In coming to the assistance of Austria, and of other nations whose intellectual life is in danger, you will be strengthening that sense of professional brotherhood which shouid unite all brain-workers, you will be taking effective and practical action to promote intel- lectual cooperation, and, above all, you will to support civilization in the struggle against the most serious peril which threatens it. Kor these reasons we are con- fident that our appeal will not be launched in vain. For the committee on intellectual coopera- tion: H. Bereson, of the “Académie Franeaise,” President G.

THE committee on the establishment of bird sanctuaries in the royal parks, appointed by 1 From the London Times. DECEMBER 29, 1922] Lord Crawford last year, has already added to the amenities of London. THarly this spring small enclosures in Hyde Park and Kensington ' Gardens were prepared by suitable fencing, a small amount of planting, and exclusion of tidying gardeners. The ‘birds accepted the hos- pitality; no fewer than twenty species, in- eluding willow wrens, great and blue tits, red- breasts and lesser whitethroats, spotted fly- catchers, carrion crows, tawny owls, pheasants and moorhen nested there this year. Accord- ing to a report just issued by the committee, it is proposed to extend these successful experi- ments. In Hyde Park the bank near the frame- house and an enclosure beside the magazine are to be allowed to grow wild, and some planting of suitable shrubs is to be carried out. The area on ithe east side of the Long Water in Kensington Gardens and a smaller enclosure on the west side are to be sanctuaries. The Dueck Island in St. James’s Park, two or three sites in Buckingham Palace Gardens, by con- sent of His Majesty, the islands in ithe lake in Regent’s Park, the wilderness in Greenwich Park, and the Isabella Plantation in Richmond Park are all to be prepared and reserved. These admirable sanctuaries, due to the imitia- tion of Mr. Harold Russell, a well-known Lon- don ornithologist, cost little, give pleasure to many, and will not incommode a single human being. They are not to incommode even the London eats, for the committee, after consul- tation with the Office of Works, decided that there was no practical cat-proof fence. But war is declared against the grey squirrels, ab- solute ito extermination in Richmond Park, and intermittent in Hyde Park and Kensington Gardens. Public sentiment will be on the side of these pleasant rogues. The charge against them, of being habitual robbers of nests, is not proven, but, were it so, there are fences in the London Zoo which retained them, and which, therefore, could exclude them from the sanc- tuaries. Their charm persists through the year, and is, indeed, even greater in the bleak months when the migrant birds have left their sanc- tuaries bare. But perhaps ithey will succeed in defeating even Lord Crawford’s competent committee.

FRANKLIN, professor of or- ganic chemistry of Leland Stanford Junior University, has been elected, as already an- nounced, president of the American Chemical Society, succeeding Dr. Edgar F. Smith, for- merly provost of the University of Pennsyl- vania. Dr. Wilder D. Baneroft, of Cornell Univer- sity, was reelected a director of the society and SCIENCE [Vou. LVI, No. 1461 William Hoskns, consulting chemist, of Chi- cago, was made a new director of the society. The following councilors-at-large for the period from 1923 to 1925 also were elected: Drs. Roger Adams, University of Illinois; G. N. Lewis, University of California; Ralph H. Me- Kee, Columbia University, and William Me- Pherson, the Ohio State University. Dr. Franklin was born at Geary City, Kan- sas, in 1862. He was graduated from the Uni- versity of Kansas in 1888 and received his master’s degree in 1890. He was a student at the University of Berlin in 1890-91; he re- ceived the degree of doctor of philosophy at Johns Hopkins University in 1894. He was a member of the advisory board of the U. S. Bureau of Mines in 1917-18; physical chemist of the U. S. Bureau of Standards and consult- ing chemist of the Ordnance Bureau of the Army during the war. Dr. Franklin’s work on hqud ammonia as an electrolitie solvent is familar to all chemists. In addition to his university work, he also was in industrial work for a number of years, serving in the sugar industry and also in the gold mining industry. In the latter work he was stationed at Miramar, Costa Rica, in 1897. Dr. Franklin was chosen from among the four nominees for president of the society who received the largest number of votes from mem- bers of the society. The choice among these four was determined by a vote of the coun- cilors. The three other leading candidates were Dr. James F. Norris, of Massachusetts Institute _ of Technology, Professor Samuel 8. Parr, of the University of Ilhinois, and Dr. Charles L. Reece, chemical director of H. I. du Pont de Nemours and Company, of Wilmington, Dela- ware. THE HAYDEN AWARD OF THE PHILADEL- PHIA ACADEMY Tur Academy of Natural Sciences of Phil- delphia announces the selection of Professor Alfred Lacroix, president of the Geological Society of France, as the recipient of the “Hayden Memorial Geological Award’ for 1923. This award was created by a deed of trust made with the academy, on April 11, 1888, by Mrs. Emma W. Hayden, widow of Dr. DECEMBER 29, 1922] Ferdinand V. Hayden, one time director of the United States Geological Survey, “as a reward for the best publication, exploration, discovery or research in the sciences of geology and pale- ontology.” The award consists of a gold medal, and is made every three years. Previous to 1900 the award consisted of a bronze medal and was made annually. Professor Lacroix was born February 4, 1863, at Macon, province of Sadne-et-Loire, France. Educated at the Lycée of Macon, at the Sorbonne and at the Collége of France, he received the degree of doctor of science in 1889. In 1893 he was made professeur at the Muséum d'Histoire Naturelle, and in 1896, director of the Laboratoire de Minéralogie, Ecole des Hautes Etudes. In 1904 he was elected a mem- iber of tthe Académie des Sciences, and ten years later he became Seecrétaire perpetual of the Section of Physics of the Académie. Pro- fessor Lacroix’s numerous and important pub- lications and discoveries, as well as his ex- haustive studies of Mont Pelée, of the phe- nomena ot contact metamorphism and endo- morphic metamorphism are familiar to all geologists.

This donation, to- gether with that of Mr. Peavey, Mr. Putt- farcken and others, represents the addition of fully 5,000 specimens, all received during the present year and this signifies that ithe Brook- SCIENCE 749 lyn Museum has attained its goal in now pos- sessing the most exclusive and authentic collec- tion of ‘birds and mammals from Long Island. Tse Hurley expedition, which left Australia in August with a flying boat and seaplane to explore the country at the head of the Fly River, Papua, has had its plans dislocated by climatic conditions.

Ir is announced by the United States Geolog- ical Survey, that the price of radium has de- creased owing to the discovery of radium bear- ing ores in Africa, which are easily worked at a much lower cost than the American mimes. This caused a drop from $120,000 a gram to $70,000, which is the lowest price at any time since radium has been used. In connection with Cancer Week, the Survey announced, the state of New York and the city of Philadel- phia have each bought two grams for the use of their citizens, and the city of Quebec one gram. THe Seismos-Gesellschaft, of Hanover, Germany, has lately issued a pamphlet on the determination of underground geological strue- tures and ore deposits by seismic methods, ap- parently an outcome of devices used in locating heavy guns in the war. The needed apparatus can be carried by two men. The work is said to be more expeditious and economical than exploration by borings. A number of sectional illustrations of investigated structures are in- eluded. THe Swedish Parliament, as reported in Eugenical News, voted, May 13, 1921, to estab- lish a Swedish Institute for Race-Biology with 82,500 crowns (Swedish) in addition to the salary of the director. Of this sum, 24,000 crowns are to ‘be utilized for the first equip- 750 ment of the imstitute, 26,500 for working ex- penses, and the remainder for salaries for as- sistants during 1922. Work began January 1, 1922. The institute has its own council, ap- pointed by the king and standing directly under the government. At present it is located at Upsala and the director is nominally on the university staff; but tthe institute is govern- mental rather than university department or agency. The first council comprises: H. Ham- marskjold, lord lieutenant of Upland; A. af Jocknick, Esq., director general in ‘the Royal Committee for Pensions, Stockholm; F.

DECEMBER 29, 1922] DISCUSSION AND CORRESPOND- ENCE RESEARCH IN MARINE BIOLOGY To THe Eprror or Science: Notices of the death of Dr. Alfred Goldsborough Mayor have referred to the lamentable possibility that the undertaking in marine biology which he direct- ed might fail to be continued. Mr. Potts,! Pro- fessor Coe,2 Dr. Davenport? and Dr. Schaeffer,* among others, have voiced or hinted at this fear, that a chief American instrument for re- search might be abandoned. Emphasis has been placed upon the unique opportunities until now provided by the Carnegie Institution Department of Marine Biology for investiga- ‘ions involving travel to more or less distant places, where material of unusually favorable type might (for a short time) be available to especially qualified students. There is another side ito this matter, and since there seems some likelihood of its being overlooked, I venture to comment upon it—for it is an aspect of marine research concerning which a continuous experience of several years as resident naturalist at the Bermuda Biological Station has given me strong con- victions. The “easy work” of zoology is ito a large extent already done—although I have had ex- pressed to me, by an eminent naturalist of the elder generation, the thought that “all the hard problems of zoology have been solved—you younger men need only to fill im the vacant spots.” (Those “vacant spots’!) Research is costly. Adequate return for money and en- ergy to be invested in biological investigation demands, and henceforth will increasingly necessitate, thatthe conditions attending inves- tigative pursuits be the least unfavorable pos- sible. Those whose varied experiences have provided an adequate background for judg- ment in this matter are unanimous in the con- viction that the most suitable locations are ito be found on the shores of tropical or semi- 1 Nature, 110, 224. 2 Amer. Jour. Sci., Ser V, 4, 173. 3 Screncr, N. S., 56, 134. 4 Science, N. 8., 56, 468. SCIENCE ‘in America is sufficiently demonstrative. 751 tropical seas. Supreme variety and abundance of animals, ease of access to them throughout the year, a comparative isolation conducive to their scholarly and productive treatment— these can be found in combination only in the warmer seas. ‘There, some of the wasteful, merely mechanical, handicaps jbo fruitful re- search are eliminated. It is not too much to itake for granted, that studies of this nature are worth while. The financial support of numerous marine stations Yet if we examine the actual operation of these existing laboratories, we find that in general they are utilized for productive work during but a small portion of the year. The splendid material possessions of the Woods Hole Lab- oratory, to take an especially noteworthy in- stance, are as good as wasted, so far as re- search is concerned, during some eight to nine months of the year. The plain fact of the matter is that the existing American institu- tions for research in marine biology are either more or less unfortunately situated, with re- gard ito ¢himatie conditions or otherwise; or else overburdened in their potentially produc- tive seasons by the requirements of elementary instruction—necessary work, and I speak of it only with respect; ‘ut it is not enough. In Mayor’s hands tie Department of Marine Biology of the Carnegie Institution had before it two large tasks—the conduct of explorative expeditions, and ithe upkeep of a fixed labora- tory serving as a central resort at favorable seasons. The workers at the Tortugas Labora- tory: being recruited from college and univer- sity staffs, and the possible season at Dry Tor-) tugas ‘brief at best, the actual time of the laboratory's session each year was necessarily short. The problems atitackable under such conditions are limited in kinds. Some truly fundamental questions can not be faced at all without intimate knowledge of faunal condi- tions over extended periods of time. The no- tion, moreover, that “favorable material” for one kind of “problem” is to be found here in this place, for another kind there in that other place, is largely fallacious. Most naturalists acquainted with the subtropical marine fauna 752 have come into contact with it during only one part of the year, and are unaware of its sea- sonal fluctuations. A permanent marine laboratory, adequately located, engaged actively in research during the whole year, I should suppose to ‘be a ecar- dinal necessity for biological development. As Mayor himself realized, the need is so obvious as to require frequent restatement; ‘his reports, and letters from him, show that ‘the realization of such a laboratory was for him a great hope. In such a laboratory inquiries become pos-- sible which in other situations can hardly be undertaken at all. Temporary social isolation would perhaps have to be faced by resident investigators, and partial loss of contact with libraries; but there are compensations. Time to “sit still and think things over,” on the ground, is of tremendous value in itself. The zoologist’s business, I take it, is to provide an account of animals, in terms, ultimately, of the properties of materials and of their rela- tions. An enormous segment of this task re- mains relatively unexplored. — d 10-8 for Geene 302800 1.00018, and those based on 2.814 X 10° for d., by 2.81355 ; 3.81400 = 0.99984. It should be noted further that Siegbahn!? has more recently obtained a value for : = sin 0 for the Ka, line of copper which does not agree with that which he obtained at the time ‘the above-mentioned ratio was obtained. His new value for 4 is 1537.302 X 10-1 for d = 3.02904 X 10-8 as compared with the CaCO3 previous value 1537.36 < 10 for d = 3.028 < 10-8. Referred to the same nee) (GENS new value of Can = 3.02855 X 10-8) this means a change from 1537.64 x 101 to 1537.056 X 10-11, a decrease of 0.038 per cent. Sinee this correction amounts to more than the difference involved in changing 3.028 X 10-8 to 3.02855 X 10-§ and 2.814 & 10-8 to 2.81355 x 10-8, and since Compton’s value for the density of rock-salt has been criticized as prob- ably too low! it seems premature on the basis of the above evidence to decide in favor of either of the two constants used by Duane.!?. A recent note by Davey! bases a similar analysis upon a value, of N = 6.0642 x 1028 and upon 2.173 gm/em? as the density of rock- salt, thus getting a.spacing for the (100) planes in this erystal of only 2.810 < 10-8 em. Adoption of this value would require extensive correction of all reported wave-lengths without any considerable advantage, and observers agree that rock-salt is a less suitable standard than calcite, on account of the greater prob- ability of inclusions leading to abnormally high densities.

The second method, depending upon the value of h, requires in addition a determination of the potential applied to an X-ray tube. The work of Blake and Duane!® may be consid- ered as a determination of d in terms of h. The values of h collected ‘by Birge!® vary some- what among themselves but 6.560 xX 10-°7 seems a reasonable mean value of the results not depending upon X-ray wave-lengths, and this gives Bencos = 3.0303 X 10-8 or 0.058 per cent. higher than the value given above. This is within the range permitted by the prob- able error in the value of h just taken.

His preliminary study convinced nim that, during the changes undergone by the spermatid as it begins to lengthen into the mature sperm, the entire distal centrole mi- grates posteriorly along the axial thread, eventually forming a terminal “plug” for the caudal sheath at its distal extremity. While a peripheral migration of part of the central ap- paratus in the spermatids of invertebrates was not hitherto entirely unknown, previous ac- counts are few in number and somewhat con- flicting in substance. A reexamination of this phenomenon was, therefore, of considerable interest. The untimely death of Mr. Driver left his work incomplete and his material was delivered to me for further study. Driver de- serves much credit for the excellence of the preparations, which are remarkably well fixed and stained. The method of Benda was used for fixation, and the sections were stained ac- cording to the alizarin-crystal violet technique. My observations were made at a magnification of 1,100 to 1,650 diameters, somewhat higher than that used by Driver in his survey of the material. After a careful study I have reached a dif- ferent conclusion in regard to the migrating “centriole’ from those of Driver and earlier observers. Although there is in the spermatids of Gicanthus a peripheral migration of a body which appears much like a centriole and stains in a similar manner, I am able to demonstrate that the migrating body is not an entire cen- triole, but only a portion or derivative of the distal centriole. In early spermatids of Gicanthus the central apparatus appears as a bar which lies per- pendicularly to the nuclear membrane. The axial thread has already appeared at this early stage. The bar constricts in the center, dividing into a proximal and a distal centriole. Almost immediately a small portion of the latter, en- circling the axial thread, is budded off and begins a migration along the thread. As it moves distally it increases rapidly in size, and eventually becomes as large as both proximal and distal centrioles combined. It reaches a permanent position at the distal extremity of the caudal (mitochondrial) sheath. The re- mainder of the distal centriole continues to lie 760 in close proximity to the proximal one at the nuclear wall; and in cells too heavily stained with crystal violet they appear as a single body, a fact which may account for Driver’s view that only the proximal centriole remains near the nucleus.
