To each chapter, where the amount of detail in the
description requires repetition, a summary has been
added to aid the beginner in fixing the important
points in his memory.

A distinct chapter has been reserved for the Treat-

ment of Syphilis; this includes, besides the thera-

peutic directions, a sketch of the sanitary restrictions,

or preventive treatment.

In conclusion, I must express my sincere thanks to

Mr. Ernest Hart, for revising the chapter on the

Affections of the Eye, and to Dr. Morell Mackenzie

for doing the same to that on Affections of the

Larynx.
