PREFACE TO SECOND EDITION.
The sale of this work has now exhausted the first edition of
five thousand copies. This happens to come at a time when I am
unusually busy in the preparation of a work on the pathology of
the dental pulp and the investing tissues of the teeth, and, as I
do not feel that a revision of this work is necessary at the present
time, I publish a second edition with the correction of a few
errors and omissions.

PREFACE TO THIRD EDITION.
It having become necessary to print a third edition of this
work, I have thought it advisable to include the essential fea-
tures of the studies of Mottled Teeth, a report of which, pub-
lished in the Dental Cosmos for February, 1916, was the last
scientific writing by my father. It was completed but a few weeks
before his death. I have also substituted in Vol. II for the chap-
ter on Pulp Treatment, the chapter on the same subject as pub-
lished in the Special Dental Pathology, which contains more of
detail. There are also a few additional illustrations.
