~SECOND EDITION, ENLARGED~

The work of Drs. Boehm and Davidoff is well known in the
German edition, and has been considered one of the most
practically useful books on the subject of Human Histology.
This second edition has been in great part rewritten and
very much enlarged by Dr. Huber, who has also added over one
hundred original illustrations. Dr. Huber's extensive
additions have rendered the work the most complete students'

"Is unquestionably a text-book of the first rank, having
been carefully written by thorough masters of the subject,
and in certain directions it is much superior to any other
histological manual."
