Part 12

A recent work by Prof. Th. Flournoy, entitled ‘Des Indes à la Planète Mars,’[G] contains an account of a remarkable case of mental automatism, or sub-conscious personality. The subject is a young woman of about thirty years, apparently in good health, but always of a nervous and imaginative type. She developed tendencies towards lapses of consciousness, hallucinations and automatic actions; and these developed later, under the inspiration of spiritualistic séances, into a series of cycles, or automatic dramas, in which the medium speaks or writes and acts under the influence of several diverse subordinate personalities. In one of these cycles--which, it must be understood, are continued from one sitting to another, although in her intermediate normal life she knows nothing of what she has said or done in the trance--she becomes Marie Antoinette, and is said to act the part with unusual dramatic skill. In another and far more elaborate cycle the scene is transferred to the planet Mars, and the houses, scenery, plants and animals, peoples, customs and goings-on of the planet are described; sketches are made, and reproduced in the volume, of these extra-mundane appearances. Still more remarkable is the appearance of the Martian language, which in successive séances the subject hears, speaks, sees before her in space, and, in the end, even writes. From the mystery of Mars we are taken to the equally mysterious Hindu cycle; here the medium becomes an Indian princess of the fifteenth century, reveals her history and that of her associates in the Oriental life, tells of herself as Simandini; of Sivrouka, her prince, who reigned over Kanara and built in 1401 the fortress of Tschandraguiri. Wonderful to relate, these names are not fictitious, but are mentioned by one De Marlès in a volume published in 1828; the author, however, does not enjoy a high reputation as a historian. When occasional utterances of the Hindu princess are taken down, they are found in part to have close resemblance to Sanskrit words; while in her normal condition the medium is as ignorant of Sanskrit as she is of any language except French, and is entirely ignorant of both De Marlès and the people of India five hundred years ago. Surely this is a tale, bristling with mystery and improbability, which, if told carelessly or with a purpose, we should dismiss as a willful invention! M. Flournoy has been unusually successful in revealing the starting points of the several automatisms and of connecting them with intelligible developments of the medium’s mental life; and the manifestations, though they remain as remarkable examples of unconscious memory and elaboration of ideas, nowhere transcend these limitations. The sketches of Martian scenery are clearly Japanesque or vaguely Oriental; the Martian language is pronounced an ‘infantile’ production, and is clearly modeled after the French, the characters being the result of an attempt to make them as oddly different from our own as possible; the Sanskrit goes no farther than what one could get from a slight acquaintance with a Sanskrit grammar; and while there is a copy of De Marlès in the Geneva Library (where the medium lives), no connection can be established between either De Marlès or the grammar and the subject of this study. Most of this knowledge of these remarkable sub-conscious states would have been impossible were it not for ‘spirit control’ of one Leopold, who, in accordance with the doctrine of reincarnation which permeates the several cycles, was in his life the famous Cagliostro. By suitable suggestion, Leopold can be induced to make the entranced subject speak, write, draw, or interpret her strange messages from other worlds; and where Leopold says ‘nay’ all progress is stopped. This case has many analogies with other cases that have been recorded, but goes beyond most of them in the complexity and bizarre character of the unconscious elaborations and in the feats of memory and creative imagination which it entails. These accomplishments, it should be well understood, never appeared suddenly or fully developed, but only after a considerable period of subliminal preparation, and then only hesitatingly, and little by little, just as is the case with the acquisitions of normal consciousness; and all these acquisitions bear unmistakable marks of belonging to the same person. The special value of this account thus lies in the accuracy of the description and the success with which the account has been made thoroughly intelligible and significant.

_THE MOSQUITOES OF THE UNITED STATES._

Dr. L. O. Howard, the entomologist of the United States Department of Agriculture, has just published a bulletin entitled, “Notes on the Mosquitoes of the United States: Giving some Account of their Structure and Biology, with Remarks on Remedies.” The author has, for some years, been interested in the general subject of the biology of mosquitoes and of remedies to be used against them, and has brought together in this bulletin all the published and unpublished notes which he has been collecting during this period. The bulletin contains synoptic tables of all North American mosquitoes, prepared by Mr. D. W. Coquillett, and gives detailed facts regarding the geographical distribution of the different species mentioned. All the five North American genera are illustrated and full, illustrated accounts are given of the life history of the two principal genera, Culex and Anopheles, as studied in _Culex pungens_ and _Anopheles quadrimaculatus_. The author calls special attention to the two genera of large mosquitoes, Psorophora and Megarhinus, and urges the importance of the study of these two genera, especially by physicians in the South, in regard to their possible relation to the spread of malaria. Considerable space is given to the subject of remedies, the principal ones considered being kerosene on breeding pools, the introduction of fish in fishless ponds, the artificial agitation of water and general community work. It is clearly shown not only that the mosquito may be, in many localities, readily done away with at comparatively slight expense, but that by careful work many malarious localities may be made healthy. The subject of mosquitoes and malaria is not discussed in the bulletin, which contains simply references to available papers on this subject, like the article by Dr. Patrick Manson, published in THE POPULAR SCIENCE MONTHLY for July, the aim of the author being to bring together all available facts about the mosquitoes of the United States, in order to assist physicians who are studying the malarial relation from the point of view of local conditions.

THE PROGRESS OF SCIENCE.

The British, French and German Associations for the Advancement of Science have held their annual meetings in the course of the past month. In each of these countries and in most other European countries, as well as in America, there are migratory scientific congresses of the same general character. As these have grown up somewhat independently, they evidently meet a common need. Science cannot be advanced by a man working independently and in isolation. The printing press was essential to the beginnings of modern science, while at the same time it was usual for the scientific student to travel from place to place that he might learn and teach. Then in the seventeenth and eighteenth centuries, as the cultivation of science became more general, royal academies were founded. The Royal Society was established at London in 1660 under the patronage of Charles II., the Academy of Sciences at Paris in 1666 under Louis XIV., the Royal Academy at Berlin in 1700 under Frederick I., the Imperial Academy at St. Petersburg in 1724 under Peter the Great, and in other cities similar academies were founded under similar auspices. Then in the first half of the present century, as science continued to grow, the more democratic organizations for the advancement of science were established. The Society of German Scientific Men and Physicians was formed, chiefly through the efforts of Humboldt, in 1822; the Swiss Association in 1829, and the British Association in 1831. Our own Association was established in 1847, but was then the intergrowth of a society dating from 1840. These associations are significant of the spread of science among all the people. Science is no longer the concern of a few men under royal patronage, but the two great movements of the present century--the growth of democracy and the growth of science--have united for their common good.

The British Association held its annual meeting at Bradford, beginning on September 5, under the presidency of Sir William Turner, professor of anatomy in the University of Edinburgh. We are able to publish, from a copy received in advance of its delivery, his presidential address, which traces the growth during the present century of knowledge regarding fundamental biological problems. The addresses of the presidents before the sections are usually written in a way that can be readily understood by those who are not specialists, and are consequently of greater interest to a general audience than some of the corresponding addresses before the American Association. The addresses at Bradford were: Before the section of mathematical and physical science Dr. Joseph Larmor discussed recent developments of physics with special reference to the extent to which explanation can be reduced purely to description; before the section of chemistry Prof. H. W. Perkin argued that radical changes should be made in the methods of teaching inorganic chemistry; before the section of geology Prof. W. J. Sollas spoke of the development of the earth, including the different critical periods in its history; before the section of zoölogy Dr. R. H. Traquair chose as his subject the bearing of fossil fishes on the doctrine of descent; before the section of geography Sir George Robertson considered certain geographical aspects of the British Empire and the changes brought about by improved means of intercommunication; before the section of economic science and statistics Major P. G. Craigie spoke of the use of statistics in agriculture; before the section of mechanical science Sir Alexander Binnie traced the historical development of science; before the section of anthropology Prof. John Rhys dealt with the ethnology of the British Isles, with special reference to language and folk-lore; before the section of botany Prof. Sidney H. Vines reviewed the development of botany during the present century. In addition to these addresses, evening discourses were given by Prof. Francis Gotch on ‘Animal Electricity,’ and by Prof. W. Stroud on ‘Range Finders.’ The usual lecture to workingmen was given by Prof. Sylvester P. Thompson, his subject being ‘Electricity in the Industries.’

Bradford is situated in the coal regions, and is an industrial center devoted especially to the manufacture of textiles. More attention was paid to local interests than is usual at the meetings of the American Association. An exhibit was arranged to show the development of the elaborate fabrics from the unwashed fleeces, and another consisting of a collection of carboniferous fossils found in the neighborhood. A joint discussion was arranged between the sections of zoölogy and botany on the conditions which existed during the growth of the forests which supplied material for the coal, and there were a number of papers devoted to the coal measures and the fossils which they contain. Another subject connected with the place of meeting was the report of the committee on the underground water system in the carboniferous limestone. By the use of chemicals the course of the underground waters has been traced, including their percolation through rock fissures, and excursions were made to the site of the experiments. The local industries received treatment from several sides. Among other discussions of more than usual interest was that on ‘Ions’ before the physical section and on ‘What is a Metal?’ before the chemical section. Features of popular interest were accounts of adventures in Asia, Africa and the Antarctic regions, by Captain Deasy, Captain George and Mr. Borchgrevinck, respectively, and Major Ross’s paper on ‘Malaria and Mosquitoes.’

The French Association met at Paris in the month of August, with the numerous other congresses. General Sebert, in his presidential address, reviewed the progress of the mechanical industries during the century and devoted the last third of his time to a discussion of international bibliography, but without mentioning the International Catalogue which now seems to be an accomplished fact. The secretary of the Association, in his review of the year, devoted special attention to the joint meetings of the British and French associations last summer at Dover and Calais. The treasurer was able to make a report that the treasurers of other national associations will envy. The capital is over $250,000, and the income from all sources about $17,000, of which about $3,000 was awarded for the prosecution of research and to defray the cost of publication of scientific monographs. The national association for the advancement of science of Germany--the ‘Gesellschaft deutscher Naturforscher und Aerzte’--held its annual meeting at Aachen toward the middle of September. An account of the proceedings has not yet reached us, but the congresses are always largely attended and the combination of addresses of general interest, of special papers before the numerous sections and of social functions, is perhaps more effective than in any other society. It also appears to be a considerable advantage for medical men and scientific men to meet together.

While from the scientific point of view the present century has been notable for the development of national associations for the advancement of science, its latter decades have witnessed a growth of international scientific meetings which may be expected to become dominant in the twentieth century. There are at least one hundred congresses, having more or less reference to science, meeting at Paris during the present summer. Perhaps the most noteworthy of these, from the point of view of the organization of science, is the International Association of Academies, which was established last year at a conference held at Wiesbaden. In this Association eighteen of the great academies of the world, including our own National Academy of Sciences, have been united to promote the interests of science. Literature is also included--of the eighteen academies, twelve include in their scope both science and literature, four are devoted to science only and two to literature only. It is planned to have a general meeting every three years, to which each academy will send as many delegates as it regards as desirable, though each academy will have but one vote. In the interval between the general meetings, the business of the Association is to be directed by a committee, on which each academy is represented. The object of the Association is to plan and promote scientific work of international interest which may be proposed by one of the constituent academies, and generally to promote scientific relations between different countries. The Royal Society has proposed the measurement, by international coöperation, of an extended arc of the meridian in the interior of Africa.

The International Congress of Physics marked an advance owing to the fact that it met for the first time this year, and it appears that the proceedings were of unusual interest. This was in a large measure due to the arrangements of the French Physical Society, which did not simply make up a programme from a mass of heterogeneous researches, but secured some eighty reports on the present condition of physical science. These were prepared by many of the leading physicists of the world and when published--as they are about to be in three volumes--will set forth the condition of the science with completeness and authority. There were in all seven sections. In the first, which was concerned with measurement, in addition to numerous reports several propositions were brought forward in regard to units, which, being international in character, are specially fitted for discussion at such a congress. As the members, however, were not in most cases delegates from governments and scientific bodies, no definite action was taken, though some recommendations were made. The decimalization of time was not recommended, nor was the proposal to give a name to units of velocity and acceleration. It was, however, decided that the ‘Barrie’ be adopted as the unit of pressure. The other sections were for mechanical physics, for optics, for electricity, for magneto-optics and radio-activity, for cosmical physics and for biological physics. Among the reports and papers of commanding interest only two can be mentioned--the introductory address by M. Poincaré, discussing the relations between experimental and mathematical physics, and one by Lord Kelvin on the waves produced in an elastic solid traversed by a body acting on it by attraction or repulsion, in which, from a strictly mathematical point of view, he advanced the hypothesis of a movable atom surrounded by an immovable ether. In addition to various receptions, a session was held at the Sorbonne, where Messrs. Becquerel and Curie gave demonstrations with radio-active substances, and one at the Ecole Polytechnique, where President Cornu showed apparatus which had been used in the determination of the velocity of light. At the close of the congress the foreign secretaries placed a crown on the tomb of Fresnel.

While a physical congress was meeting at Paris this year for the first time, the Geological Congress, which was one of the first international congresses to be organized, held its eighth session, beginning on August 16. America, in spite of the number and importance of the inventions it has given to the world, has not as yet done its share for the advancement of physical science, but in geology it occupies a foremost place. It was natural, therefore, that while American physicists were scarcely represented on the programme of the Physical Congress, they occupied a prominent place on the programme of geological papers. Among the three hundred members present, the representation from America included Messrs. Stevenson, Hague, Osborn, Ward, Willis, White, Cross, Scott, Todd, Kunz, Choquette, Adams, Mathew and Rice, and they presented a number of the more important papers. M. Karpinsky, the retiring president, gave the opening address, which was followed by an address of welcome by M. Gaudry, the president of the congress. A geological congress can offer special attractions in the way of excursions, and these were admirably arranged on the present occasion--both the shorter excursions to the classic horizons in the neighborhood of Paris and the more extended ones that followed the close of the meeting. The guide for the twenty long excursions and numerous shorter trips, prepared by the leading French geologists, was an elaborately illustrated volume representing the present condition of our knowledge of French geology. The ninth geological congress will be held at Vienna three years hence.

The International Congress of Mathematics met for the second time at Paris, though there had been a preliminary meeting on the occasion of the Chicago Exposition. There were about two hundred and twenty-five mathematicians in attendance, including seventeen from the United States. M. Poincaré presided, and the vice-presidents, some of whom were not present, were Messrs. Czuber, Gordon, Greenhill, Lindelöf, Lindemann, Mittag-Leffler, Moore, Tikhomandritzky, Volterra, Zeuthen and Geiser. The sections and their presiding officers were as follows: (1) Arithmetic and Algebra: Hilbert; (2) Analysis: Painlevé; (3) Geometry: Darboux; (4) Mechanics and Mathematical Physics: Larmor; (5) Bibliography and History: Prince Roland Bonaparte; (6) Teaching and Methods: Cantor. Valuable papers were presented by M. Cantor on works and methods concerned with the history of mathematics, by Professor Hilbert on the future problems of mathematics and by Professor Mittag-Leffler on an episode in the life of Weierstrass, but the programme appears to have been not very full nor particularly interesting. Time was found for a half-day’s discussion of a universal language, but not to carry into effect the plans begun at Zurich three years ago for a mathematical bibliography. The next congress will meet four years hence in Germany, probably at Baden-Baden.

The untimely death of James Edward Keeler, director of the Lick Observatory, is a serious blow to astronomy and to science. Born at La Salle, Ill., forty-three years ago, he was educated at the Johns Hopkins University and in Germany. When only twenty-one years old he observed the solar eclipse of 1878, and drew up an excellent report. Three years later he was a member of the expedition to Mt. Whitney under Professor Langley, whose assistant he had become at the Allegheny Observatory, and whose bolometric investigations owe much to him. He became astronomer at the Lick Observatory while it was in course of erection, and in 1891 he succeeded Professor Langley as director of the Allegheny Observatory. He was called to the directorship of the great Lick Observatory in 1898. Keeler’s work in astrophysics, including his photographs of the spectra of the red stars and his spectroscopic proof of the meteoric constitution of Saturn’s rings, demonstrated what he could accomplish at a small observatory unfavorably situated. At Mt. Hamilton he was able in the course of only two years to organize thoroughly the work of the Observatory, and to adapt the Crossley reflector for his purpose, taking photographs of the nebulæ that have never been equalled. His discovery that most nebulæ have a spiral structure is of fundamental importance. It is not easy to overestimate what might have been accomplished by Keeler in the next twenty or thirty years, both by his own researches and by his rare executive ability, for it must be remembered that his genius as an investigator was rivaled by personal qualities which made his associates and acquaintances his friends.
