PHILADELPHIA. PREFACE. 
In issuing a little volume of this character it is 
perhaps but just to say that of course it cannot, 
and is not intended to, replace the larger works of 
the same class. For more minute information, 
extended description and elucidation, suggestions 
for treatment, and other minutiae for which the 
work of reference is consulted, recourse must be 
had to more extended dictionaries, text-books, and 
similar sources of information. 
Nevertheless, it is confidently believed that the 
present volume meets a distinct and imperative 
need of the student, conveying in condensed and 
convenient form concise explanations of innumer- 
able terms for which he is liable to have continual 
use. The medical student daily meets unfamiliar 
technical and scientific terms, of the meaning of 
which it is important he should have immediate 
knowledge—not necessarily an. exhaustive exposi- 
tion, but a hint, a clue—and it is hoped thjs little 
work will supply the desired key. Pains have not 
been spared to insure accuracy of terminology, ac- 
centuation and definition, and the work is supple- 
mented with several useful tables, of factors fre- 
quently used in the etymological construction of 
our medical nomenclature, etc. An appended list 
of Antidotes adds to the value of the volume.

RICHARD C. NORRIS, A.M., M.D., 
DEMONSTRATOR OF OBSTETRICS IN THE 
UNIVERSITY OF PENNSYLVANIA.' 
Price, Cloth, Interleaved for Notes, $2-00 Net. 
***The New York Medical Record of April 19th. 1890, 
referring to this book says : “ The modest little work is so 
far superior to others, on the same subject, that we take 
pleasure in calling attention briefly to its excellent features. 
Smalt as it is it covers the subject thoroughly and will prove 
invaluable to both student and the practitioner as a means 
of fixing in a clear and concise form the knowledge deriyed 
from a perusal of the larger textbooks. The author deserves 
great credit for the manner in which be has performed his 
work. He has introduced a number of valuable hints which 
would only occur to one who was himself an experienced 
teacher of obstetrics. The subject matter is clear, forcible 
and modern. We are especially pleased with the portion 
devoted to the practical duties of the accoucher, care of 
child, etc. The paragraphs on Antiseptics are admirable, 
there is no doubtful tone in the directions given. No details 
are regarded as unimportant. No minor matters omitted. 
We venture to say that even the old practitioner will find 
useful hints in this direction which he cannot afford to 
despise.”
