This book in all probability will take its place among the first favorites of the text-books dealing with the subject of which it treats. There is no criticism to offer of the manner in which the subject is presented. Possibly the section on microscopic technic will be found rather short and not complete enough to replace satisfactorily special works on technic. The publishers have done their part well. The illustrations are all creditable, some being excellent. The translator and editor has given due attention to recent American investigations in histology and microscopic anatomy.
