PREFACE.

SECOND EDITION.

The preparation of the present edition of this work,
has been attended with more labor and effort, than

the author had anticipated.
The first edition at the time of its writing was de-
signed to embody and present the principles and prac-
tice of the profession in the operative department, in
its highest attainment.
Since that time, however, so great have been the
changes in many points of practice and application of
principles, that those given as the best, nine years
ago, are superseded by others and out of use ; so that
in many particulars the labor has been almost equal
to the preparation of new matter.

The object in this, as in the former edition, has been
to bring the work up to the present status of the pro-
fession ; and though it has been accomplished with
many misgivings and consciousness of defects, the
author is not without hope that it may be of value to
those preparing to enter the profession, if not to those

already in it.
Cincinnati, April 1, 1868.
