This is a most interesting contribution, dealing largely with the gross anatomy of the brain. Most students of cerebral comparative anatomy have devoted themselves to a study of the tracts and nuclei; that is, the comparative anatomy of brains cut into microscopic sections. Professor Anthony takes the brain as a whole, discusses its weight, its general form, its flexures and its axis.
In the introduction there is a review of the structure and function of the elementary nerve cell, and a description of the division of the nervous system into the cerebrospinal and sympathetic systems. The embryologic development of the cerebrospinal system is described. The general form of the brain is discussed in chapter 1: the structures visible from the superior aspect of the brain of mammals are telencephalon, metencephalon, and myelencephalon, with rarely the corpora quadrigemina and epiphysis. In man only the telencephalon is visible from the top. On
