change precludes the need to install a hemi spheric bowl for ganzfeld stimulation within the shielded enclosure where testing is con ducted. Formerly, we presented the stimulus light in Maxwellian view (light focused in the plane of the pupil) via fiber optic wave guides and condensing lenses. The loss of light intensity by the fiber optic system is considerable. The stimulus efficiency is in creased by making the above change. JEROME T. PEARLMAN,

INTERNAL MEDICINE,
This is the third volume of a series of 24, edited by Lloyd H. Smith, Jr. A list of the subject matter of future volumes is printed opposite the title page and it includes a variety of disorders. The editor could not have selected a more qualified author to write volume 3, and the results are excellent. Systemic vascular dis ease so commonly involves the ocular struc tures that this text should be valuable to all medical disciplines concerned with any phase of vascular abnormalities. Although the text comprises only 154 pages with 118 illustrations, there is an ex tensive bibliography of 709 references. The descriptions of the ocular manifestations in general are brief but complete and are ref erenced toward further reading. The index is detailed. The illustrations are of unusual clarity. The nine chapters, each further subdivided are: External ocular signs, Fundus, Sig

nificance of fundus signs, Subjective symp toms and visual field abnormalities, Fundus signs of systemic vascular disease, Occlusive arterial disease in the eye, Occlusive venous disease in the eye, Vasculitis, and Neuroophthalmic complications of intracranial vascular disease. Each chapter closes with a summarizing section. There is little to criticize adversely in this textbook for it is written in the clear and concise style that characterizes Dr. Cogan's previous works. The technique of ophthalmodynamometry in Figure 22 portrays the application of the instrument to the nasal sclera, which is cumbersome and inaccurate. Application to the lateral sclera is the normal method. Furthermore, the Bailliart dial ophthalmodynamometer shown in the same illustration is the most inaccurate and least reliable of the available models. Figure 65 shows a typical fibrin-platelet embolus at a fork of a retinal arteriole but labeled retinal arteriosclerosis. In Figure 88, a calcine or fibrin-platelet embolus lodged in the fork of the central retinal artery in the center of the optic disk is disregarded as the cause of occlusion of the central retinal ar tery. But these are minor exceptions, in an otherwise fine book, recommended not only for ophthalmologists but anyone concerned with systemic vascular disease. ROBERT W .
