Convinced that anatomy and biology constitute the foundation on which medical education—especially the training of the specialist—should be based, Dr. Claoué has written an instructive textbook on the internal ear. There is a short introductory chapter on development which leads to an account of maldevelopments met with in practice, as well as of the neurovascular pathways along which infection may spread from the ear to the subarachnoid spaces.
The main text is divided into three parts: The first deals with anatomic, pathologic and clinical considerations of the inner ear; the second, with the technic of microscopic examination, and the third, with a study of the ear of the guinea pig. In the first part the inner ear is described, region by region, in separate chapters, each being introduced by a short anatomic review.
