General summary ......... 9 Bibliography 10 Explanation of plates .......... 10 A. INTRODUCTION. It is now generally recognized that the comparative anatomy of tin nervous system can not be profitably studied without recou/se t( microscopic analysis in the peripheral region as well as in the centra organs. It is further recognized that, for their final explanation, th< highly complex nervous organs of mammals, including man, mua await the revisions and additions which such a method of study applied to the lower vertebrates, will suggest for their interpretation Inasmuch as the nervous system is essentially a correlating structun it follows naturally that changes in its mechanism should be studie in connection with a study of the correlated organs and function.'' This gives to the study of the nervous system a broader biologic, significance than is possessed by other organs. But this relation adi much to the technical difficulties and makes it almost impossible tj bring within the scope of a single research the complete analysis 1 even a single form. The shortcomings of the present study from th; point of view are recognized by the author. However, in the methoi pursued, he has had constantly in mind the larger problem, whi< does not recognize the arbitrary distinction between central and p ripheral nervous systems. In fact, he has already collected mm material and information on the central nervous system of Anoli but it seems advisable to reserve that material for a more compl< account of the Anolis brain. The present investigation is carried i enough toward the nerve centers to articulate easily with such a stud;
