A consideration of apoplexies in general based on the study of a large series of cases has long been needed to confirm or disprove many of the current theories of the mechanisms of the various types of cerebral vascular accidents. Schwartz has studied hundreds of cases and in his book illustrates his results graphically by means of many beautiful photographs. He considers the macroscopic and microscopic observations in hemorrhage associated with hypertension, in softening associated with arteriosclerosis, and in embolism. He has a complete discussion of the pathogenesis of these various types, comparing and contrasting them in great detail. His conclusions are based on a thorough study and should be read in original detail by all interested in cerebral vascular diseases.
