From the foregoing measurements it will be seen that, while the length is less, the expanse is greater than those published. These swifts were first observed by Professor Bruner while on a government entomological expedition in the summer of 1891. At the direction of Professor Bruner his ornithological assistant, Mr. J. B. White, shot and prepared the above specimens this past summer. Being in charge of the Morrill geological expedition sent to this region by the University, I had occasion to fall in with Professor Bruner's party, and to observe these swifts personally. We must have seen several hundred at Squaw Canon flying in and out among the buttes which rise with nearly vertical walls five hundred to twelve hundred feet above the Hot Creek Basin. Having occasion to visit this region several times annually with parties of students, it is to be hoped that we may obtain data for further notes, and that it may be possible to secure their nests and eggs, in spite of their inaccessible abodes.

A JOURNAL OF TWO SUMMER CRUISES account for the incredible velocity attributed to the Star 1830 of Dr. Brendel's Photographs of Auroras. IN your issue of July 22, 1892, you copied from The Scottish Geographical Magazine an interesting notice of the expedition made by Dr. Martin Brendel and Herr O. Baschin to Bossekop on the northern coast of Norway, last winter, to study the northern lights and attendant phenomena. Therein mention was made of the photographs of the aurora obtained by Dr. Brendel. By his courtesy copies of some of these pictures are before me. Dr. Brendel modestly regards them as valuable chiefly for what they promise for the future. He hopes to visit the Arctic regions again with a much better equipment. But he has already achieved a great feat in securing even these photographs, the first of the kind ever taken. Tromholt's attempt in 1885 cannot be regarded as a success. The faintness of the light, the quivering and shifting of the auroral rays, and the non-actinic quality of certain colors, combine to make this a very difficult task. Dr. Brendel Exchanges.

THE GEOLOGICAL PUBLISHING CO., Minneapolis, Minn. does not say who manufactured the plates which he used; but they measure four by five inches. With a steady, diffused glow on an arch he has had very fair success, with an exposure of between forty seconds and five minutes. With a greatly agitated, curtain-like display, and an exposure of only one minute, he lost all detail. But a very sharp picture was secured, with an exposure of six seconds, of one end of an arch, which was composed of radiant streamers; the structure is distinctly shown. The pictures were obtained between Jan. 4 and Feb. 1, this year. On the night of Feb. 13-14, a heavy snow-storm prevented observations of the famous aurora of that date; but, as has already been mentioned, a remarkable magnetic disturbance was recorded by the needles. The scientific world will wish Dr. Brendel good luck in his future endeavors, and will watch eagerly to see whether he finds it practicable to determine the parallax of auroras by this method. JAMES P. HALL. Brooklyn, N.Y., Oct. 8. BOOK-REVIEWS. The Horse: A Study in Natural History. By WILLIAM H. FLOWER, Director of the British Natural History Museum. New York, D. Appleton & Company. 66 THE Modern Science Series," edited by the distinguished scientist, Sir John Lubbock, is not primarily designed for the specialist, nor, on the other hand, for the class of readers that reads merely to be entertained. It attempts rather to supply accurately, yet in language divested of needless technicalities, such information as is needed by everyone who desires to keep fairly abreast of the progress of modern knowledge. The name of the author of the present volume is in itself a guarantee of the accuracy and interest of its contents, and in the reading we are not disappointed; for within 204 short pages the Dyspepsia Dr. T. H. Andrews, Jefferson Medical College, Philadelphia, says of Horsford's Acid Phosphate. horse and its relations to nature are presented in a sketch which is at once attractive and thorough. In the first chapter the ancestral relations of the horse are especially considered; the second chapter discusses chiefly the horse's living allies; while the third and fourth chapters are devoted to structural features. But what adds unusual interest to the book is that the bearing of the facts upon the origin of the horse is in every chapter constantly kept in view. "The anatomy and history of the horse are . . . often taken as affording a test case of the value of the theory of evolution, or, at all events, of the doctrine that animal forms have been transmuted or modified one from another with the advance of time, whether, as extreme evolutionists hold, by a spontaneous or inherent evolving or unrolling process, or, as many others are disposed to think, by some mysterious and supernatural guidance along certain definite lines of change." The conclusion is forced home to the reader that the horse is a very highly specialized type derived from a generalized ancestor by slow and gradual change, or evolution. The one-toed animal was once five-toed, and its heel was less raised above the ground than now; its teeth were once fitted for a much wider range of diet; its neck was short and a collar-bone, now absent, was once present; its tail was long; its brain - and especially the cerebrum was small; instead of the open plain, it frequented the shady or often marshy borders of lakes and streams. The various pages in the history of this evolution are presented as they have been recorded in the book of nature till at last the genealogy is traced back to the five-toed and otherwise generalized type, Phenacodus,, of early Eocene age. The work is illustrated with twenty-seven clear, well-selected cuts, of which that of the quagga deserves especial notice as being from the first photograph known to have been taken from the living animal. The external appearance of the book is unusually attractive. RACES AND PEOPLES. By DANIEL G.

In the first part of this work the author dwells on the errors in our mode of treating Neurasthe subject which still prevails; in the secthenia, consequent on the wide ignorance of ond part, attention is drawn to the principal' causes of the malady.

To the Readers of SCIENCE: During the past year it has been found possible to enlist the interest of scientific workers in the success of Science to such an extent that more than nine hundred have promised contributions during the coming twelve months. Not only are contributions of merit coming in ever increasing numbers from American scientific men and women, but we are now securing our first contributions, in ar y quantity, from abroad. We know that this development in the usefulness of Science is appreciated, not only from the many kind letters received, which are always inspiring and which we wish our friends would mark as at our disposal for publication, but from a marked increase in the number of new subscribers. Science owes its existence to the munificence of two gentlemen, whose names we do not feel at liberty to publish, who contributed very nearly $100,000 toward the support of the paper in its early years. There is no longer need of such liberal subsidizing, but we do need cash subscriptions from all who feel at all interested in a weekly journal of science in America. There is no question that scientists are cosmopolites and that a journal is the more useful to them the more it is international in its character. As the result of our efforts to develop the use of Science abroad, we have recently published articles from V. Ball, Dublin; Edward T. Dixon, Cambridge, England; A. H. Keane, London; David MacRitchie, Edinburgh; Edward Seler, Berlin; Isaac Driving the Brain at the expense the brain we the body. Ex- make healthy flesh-refreshing sleep-such are methods.

Liveing, Cambridge, England; the Marquis de Nardaillac, New Method of Protecting Property To develop this international feature of the paper an enlargement to twice its present size will be necessary, and an increase of the price to six dollars. If we can secure a sufficient increase in the number of subscribers we can promptly enlarge and improve Science still further, but cannot without, as in the past the work, as will be seen, has been largely a labor of love. Within the acquaintance of each of our readers there must be some one sufficiently interested in the development of what we hope is a valuable means of scientific discussion to subscribe six dollars, and we urge each and all our friends to do what they can to help. If the number of new subscribers is as large as we hope, one half of the enlarged Science would be printed and published in London to facilitate promptness of publication. Form of Subscription. N. D.
