PREFACE 
This book is written as a companion to the author’s Manual 
of Gynecology. It also presents, as far as possible on the printed 
page, the methods of teaching the subject he has used with 
satisfaction for the last twenty years. Throughout the book 
an elfort has been made to present the subject clearly and con- 
cisely, and to avoid all unprofitable discussion. The methods 
of treatment and technic of operations advocated have all been 
tested in practice and have given satisfactory results. 
The scope of the book has been rather sharply limited. A 
minimum of embryology has been included. Diseases of the 
newborn child are included only in so far as they occur during 
the puerperium. The chapters on lacerations of the birth-canal 
and consequences of childbirth, while differing somewhat in 
scope, are necessarily very similar to the same chapters in the 
Manual of Gynecology. 
A new classification of deformities of the pelvis is presented, 
classifying them according to their most prominent deformity. 
This method has been found easier for the student to remember, 
and simplifies the discussion of their management. 
Especial care has been given to the description of the mechan- 
ism of labor, with a view to simplifying this, to the student, 
most puzzling subject. The illustrations in this chapter have 
been chosen with the idea of enabling him to visualize the dif- 
ferent presentations, a thing most essential in the proper appli- 
cation of forceps. 
The longest chapter is that on the obstetric operations. Es- 
pecial care has been given to a somewhat extensive description 
of that most dangerous of all obstetric instruments, the forceps. 
The different operations are all detailed, with indications, contra- 
indications and the steps of their performance. 
The entire subject of obstetric hemorrhage is to be found in 
one chapter, with precise directions as to management. 
This book, like the Manual of Gynecology, is presented with 
the hope that it will be found useful by both medical student 
and practitioner, whose time for voluminous reading is limited.
