This is a masterly guide to the science of histology, without which neither anatomy nor physiology can be properly comprehended. It is, as the preceding work, a treatise on microscopical technique, but, as its name indicates, is strictly confined to the subject of histology. The present issue is a thorough revision in every respect, and contains much additional matter. Although the work is very concise, compressed in 488 pages, it contains all the essentials upon the subject of normal histology. We commend the work to our readers, feeling sure they will not be disappointed in it.
