This extensive monograph on the cerebrospinal fluid is one of the most thorough and complete works on the subject. An enormous mass of detail, concerning the normal values for the chemical and physical properties of this fluid, has been arranged in a most serviceable and interesting manner. In the second portion of the work, the pathologic variations in theee properties are so fully discussed that little is left to be desired.
The style of the book is clear and concise. The arrangement of the subject-matter is excellent. This book is one which should be in the library of every laboratory worker and should porve of great interest and value to the clinician.
