“…Without seeking to present an adequate survey or bibliography of the work which is largely based upon Pryor's pioneer investigations one might refer to Miss Sawtell's recent work in which she extended the method to include lower end of radius and ulna (6,7). That there is value in this method there is no doubt.…”

“…Sawtell (1928) had used the X-ray to study sex differences in the bone growth of young children, and considered that sex differences appeared constantly in the acceleration in the female in areas of spreading ossification and an early differentiation in the breadth of the male radius and the size of the head. The rate of calcium metabolism was suggested to be more rapid in females, with a greater resistance to tetanus and rickets.…”

Although a quick glance at the abstract and contents pages seems to indicate a wellstructured, carefully thought-out and coherent thesis, the production of this was not a rational process. I am privy to an occasional reminder of this when delving into a drawer of my desk and discover some long-abandoned and deservedly forgotten draft of this thesis. To be given three years or more spending time reading in the many libraries attached to this University is a rare privilege, and 1 count myself very fortunate to be able to do this.This thesis had its ontogeny through the patience of Dr. Diana Mason, a brilliant and much-loved obstetrician in Wellington. My initial interest had been stimulated by gynrecological activities, and especially from reading descriptions in childbirth literature about 'cephalopelvic disproportion' describing an indication for operative delivery. This indication has the effect of a red rag to a bull for heirs of Dr. Pangloss' such as myself. It seemed to indicate a maladaptation, a misproportion or mismatch between what the mother was physically capable of bearing, and what the neonate grew to. I felt sure there was some key to understanding why cephalopelvic disproportion still occurred. Perhaps the father's size had some relationship? Surely such disproportion would have otherwise rapidly disappeared by the normal processes of natural selection. The title with which I registered for a Ph. D. reflected such aspirations: "Racial diversity in pelvic architecture and cephalopelvic disproportion in New Zealand". Physical anthropology with an obstetrical slant.

“…Kjerrulf (77) contributes height and weight measures on 1,244 Swedish children between seven and fourteen years of age. Heart action (87), bone growth (112), myopia (119), and growth of head-form (133,134) have all been subjects for careful study. They are not here discussed, but the references given briefly abstract the source material.…”

Since 1927, the field here to be reviewed has opened up at an increasingly rapid rate. A good beginning can be made with Langdon-Davies' popular chapter on the " history of human ideas about sex differences " (79). Five factors are cited as causing the myth of the " female character," and a prophecy of the future of womankind is attempted. Sumner and Keller (124) present a vast amount of carefully gathered and documented data on the social side of sexual relations, especially in primitive man. Briffault (21), a British anthropologist, offers extensive and exhaustive documentation for his thesis that the basis of human culture lies in the primitive sentiments about woman in her reproductive capacity; his three volumes contain approximately 2,300 pages. Bauer (10,11), a Viennese gynecologist, tries to prove that sex determines all of woman's actions, no matter how trivial, from birth to death, citing many references in his study of the physical, mental, sexual, and erotic aspects of feminine life. Scheuer (113) offers a historical contribution to the psychology of sex. Heilbron (60) believes woman to be inferior, " above all in the central organ, the brain." A good bibliography of titles, from classical literature to modern experiment, is found in Weith-Knudson's popular book (128). The feministic note is represented in such studies as that by Kennedy (76), using a Japanese setting.Turning to bibliographical studies, it will be unnecessary to more than mention the following: Allen (2), Ellis (44), Lincoln (86), Louttit (88, 89), Scheuer (114,115), and Woody (135) ; these give the careful student the key to the better material. In addition, Goodenough's (54) statement of a program for future research, together with a short summary of some studies in this field, is important and stimulating. Current work on sex differentiation and sex determination in animals is reported in such periodicals as the /. of Exper. Zoology and the Biol. Bull, for 1928 and 1929 especially. II. Physical Differences. Anatomical studies may be passed over rapidly in favor of studies of behavior differences. Over one thou-
