been emphasized in recent literature, including experimental work on the projection of the retinal fibers along the visual pathway, new perimetric ap­ paratus and technique, and the newer thought and experience with regard to the fields in glaucoma, the central or cecocentral scotomata of toxic amblyopia and nasal sinus disease, and vis­ ual field changes in the amblyopia of squint. The writings of other authors on their particular topics are freely quoted, with due acknowledgment. The value of some of the new and expensive ap­ paratus for perimetry is carefully ap­ praised. Special attention is called to the author's method of anatomic or physiologic recording of the fields; ac­ cording to which the chart represents the patient's field as viewed by the ex­ aminer in a position facing the patient, instead of depicting the field as looked at by the patient himself. This volume has served and will con­ tinue to serve, not merely as a guide to careful technique, but as a source of reference with regard to conflicting the­ ories and scientific experimentation in difficult problems of ocular and cerebral diagnosis.

Pub­ lished by the authors, Chicago. Probably few of us have fully real­ ized the educational possibilities of stereoscopic photographs. Especially in teaching those who are unfamiliar with the conditions depicted, a good illustra­ tion, and particularly a stereoscopic pair of photographs, with its faithful in­ dication of the relative depths of dif­ ferent structures, possesses some dis­ tinct advantages over even careful ex­ amination of the living subject. The photograph may be examined as long and as frequently as is desired, whereas the owner of a congenital anomaly or the sufferer from some disease of the anterior segment may become intoler­ ant of illumination and manipulation.

NOTICES

This second series of fifty stereo­ scopic photographs has the splendid quality of the first series; and each pair is carefully described on a separate card. Among the many interesting con­ ditions illustrated may be mentioned ectopia lentis, persistent pupillary membrane, embryotoxon, glass within the corneal scar, steel in the iris and in the lens, gunpowder under the con­ junctiva, traumatic rupture of the an­ terior capsule of the lens, traumatic rupture of the iris, pediculosis of the eyelashes, molluscum contagiosum, rosacea keratitis, tuberculous keratitis, dendritic keratitis, separation of the epithelium of the cornea following a fistulization operation, central atrophy of the iris, vascular tumor of the iris, melanoma of iris and sclera, and sar­ coma of the ciliary body. The photographs and the descriptive cards are conveniently fitted into a strong, leatherette-covered box.

Hereditary optic atrophy (Leber's dis­ ease). Julia Bell, M.A., M.R.C.P. Paper, quarto, pages 325-423. Frontispiece portrait of Leber, and pedigree plates. Figures 704-941. Cambridge University Press, Lon­ don, 1931. This is part 4 of the Nettleship Me­ morial Volume, Anomalies and Dis­ eases of the Eye, and is a part of "The treasury of human inheritance," edited by Professor Karl Pearson, F.R.S., from the Francis Galton Laboratory for National Eugenics of the University of London. An outline of the history is followed by an account of the dis­ ease, including: the sex incidence, the character of the onset, and the age at which it occurs; the clinical signs and symptoms of the disease; the course and prognosis; and the association of other disabilities. The final section deals with the hereditary character of the disease and its mode of transmis­ sion. After the name index there is a bibli­ ography extending from Beer in 1817 through 153 titles to Ida C. Mann and H. M. Traquair in 1928. The descrip-
