That this excellent book should have passed through five editions in the course of nine years would seem to be ample evidence of its value. It presents a careful detailed study of the examination of the entire nervous system, lucidly informing the reader how each step should be performed, the interpretation to be placed on the observations and the pit-falls to be avoided. The additions to this edition concerning ventriculography and encephalography are valuable addenda. The text is not concerned with the discussion of clinical or pathologic entities; this is a great advantage over other books on neurology as it lends to the brevity, conciseness and clearness which characterize this little volume. It should continue to find an important place among the books of the student of neurology and also the practitioner of general and specialized medicine.
