paid to pseudo-science-astrology, alchemy, physiognomy, oneirology-for "it is not always easy to distinguish a pseudo-science from one which is sound but imperfect." Very little space is allowed to the work of magicians because "their purpose was but too often of a sordid nature," and quite different from the ideals of theologians and scientists. The author says: "Theologians were trying to reach the same goal as the men of science; they generalized prematurely; they were walking along the same road, but much too fast. Magicians did not follow that road at all; they were sidetracked or turned in hopeless circles." There is nothing in Sarton's study to support the doctrine that magic stimulated experimental science. "Magic is essentially unprogressive and conservative; science is essentially progressive; the former goes backward; the latter, forward."

The present volume is an introduction to the history of science from Homer to Omar Khayyam. The marking of the initial and end periods by these great literary names may seem strange to one who does not remember that in Homer there are matters of interest on geography, astronomy, anatomy, medicine, surgery and metallurgy, and that Omar Khayyam was a distinguished writer on mathematics and astronomy. Early Babylonian, Egyptian and Chinese science is not given in this volume because "it is not yet possible to give a continuous account"; this early science will be presented in separate chapters later when it is expected that "our knowledge of these difficult subjects will be materially improved."

The treatment is chronological. From the ninth century B. C. down through the eleventh century, the subject matter is presented in thirty-four periods varying in length from two centuries to half a century. The comprehensiveness of Sarton's scheme appears from his consideration in each period of the contemporaneous science of all the countries of the old world which were scientifically active at that time. The broadened viewpoint thus gained may be illustrated by the seventeenth century which Henry Hallam, with a vision confined to Europe, had called the nadir of the human mind; Sarton, in a more comprehensive view, finds the first half of that century "a golden age in at least four countries-Arabia, Tibet, China and Japan." The heading of each period after the first two bears the names of one or two outstanding scientists; thus we have "the time of Thales and Pythagoras," "the time of Hsüan Tsang," etc. It is of interest to notice that of the thirty-four names, sixteen are Greek or rather Hellenistic, five are Roman, three are Chinese, two are Byzantine, one is Persian, three are Muslim, one is Western European. The treatment of the different periods is according to a uniform plan. First comes a survey of science

in the period considered, then a presentation of the individual scientists classified by the subjects (religion, philosophy, mathematics, astronomy, geography, alchemy, medicine, historiography, law, or philology) in the cultivation of which they were respectively most conspicuous. A very compressed outline of the life and work of each writer is given, followed by a bibliography which in the case of prominent men like Galen covers several pages. Sarton says: "The best way of using this work is to read the introductory chapter and the first section of succeeding chapters, and to consult the other sections only as far as may be necessary to satisfy one's curiosity or to find an answer to a definite question."

Sarton's work is written under the dominance of his conviction that the proper procedure is not to pursue first the history of some one science and then take the history of other sciences, one at the time. This tandem arrangement is repugnant to his ideals. One should study, not the history of the sciences, but the history of science. Moreover, one should not confine one's attention to any one country like Greece or India, but should take a world view of scientific achievement. Such a synthetic process alone will afford a full picture, free of distortion, of the intellectual progress of mankind.

The work is prepared with freedom from national bias and with painstaking care. If the great discovery of the precession of the equinoxes is attributed to the Greek Hipparchos, rather than to the earlier Babylonian astronomer Kidinnu, it is because the positive proof of Kidinnu's achievement has been published only recently, while Sarton's volume was going through the press.

The endeavor of the author, we take it, has been not to produce a book which would rank among the "best sellers," but a book which would be a real vade mecum to all serious students of the history of science. It ought to be in every college library. Readers having already a modicum of knowledge of the history of science, at least in one field, are the ones who will profit most by this publication. Dr. Sarton has the scientific and keen philosophic insight which are necessary for successful historical research in this field. He and many other modern lovers of systematized positive knowledge, when contemplating the achievements of science since the time of Homer in lifting man to higher intellectual endeavor, would hardly hesitate to invoke the scientific spirit in the words which Lucretius addressed to Epicuros: "Thou, father, art discoverer of things, thou furnishest us with fatherly precepts, and like as bees sip of all things in the flowery lawns, we, O glorious being, in like manner feed from out thy pages upon all the golden maxims, golden I say, most worthy ever of

AWARDS FOR RESEARCH AT THE UNIVERSITY OF CALIFORNIA MANY members of the University of California faculty have received awards from the research fund of the university to carry on scientific and scholarly research next year. The research fund was created by the Board of Regents in 1917-18 with an initial appropriation of $2,000. For the academic year 1927-28 the regents have appropriated $85,000 in support of specific research projects. This sum is considerably supplemented by balances available on June 30, 1927, and by liberal donations from individuals and foundations. Grants in support of research are made by the president with the advice of the Board of Research, a committee of the Academic Senate, to individual members of the university or to departments on the basis of the merits of their projects and estimates of the cost.

The data show definitely that once puberty is established, which occurs in the albino rat at about 65 days of age, the ratios between humerus length and body length, and femur length and body length are practically constant, notwithstanding the actual increases which take place in bone and body size. Thus given a humerus or a femur of a male or female albino rat of 65 days of age or over, it is possible to compute from its length the body length of the animal from which the bone was taken, and from this the approximate body weight as well as that of the several organs, more particularly the brain and spinal cord, by the use of the "standard" values established by Donaldson.

LONG-BONE LENGTH AND BODY SIZES IN going over some bone-length, body-length relations observed in a series of albino rats used as conthe trols for another study, it was noted that a singular consistency in ratios existed, regardless of age or body size, once the animals had passed the pre-pubertal stage of development. On remarking this to Dr. H. H. Donaldson, of this institute, he reminded me of the idea attributed to Cuvier that it should be possible to reconstruct an animal from a single bone. While I have been unable to track down this statement in the literature, the figures in the accompanying table show that the principle is not at all preposterous, providing certain obvious limitations are recognized.

It will be noted that, of the two bones, the humerus length bears the more constant ratio to the body length, that of the femur tending to increase slightly with age. While this increase is numerically small, its occurrence in both sexes, combined with the fact that the humerus length-femur length ratio consistently decreases with age marks the distinction as valid, and indicates that of the two the humerus is the better bone for reconstruction purposes.
