This volume, the first of two, is designed by the author to fill a long felt gap in neurologic literature. Clinical neurologists usually have had an early training in anatomy and pathology of the nervous system but until recent years have been little concerned in physiologic problems, even though their field has given them excellent opportunity to study human physiologic experiments. To enable the neurologist to correlate his anatomic background with physiologic methods and to stimulate their application to the clinic, Spiegel has written this excellent book. Naturally, in such a work, modern neurologic conceptions of each chapter of neurology are excellently summarized, so that the book is of extreme value not only to the clinician but also to the investigator. The first volume alone is the most stimulating of recent neurologic monographs.
