The rapid sale of the first edition, of three thousand copies, in but a little over two years, is a gratifying assurance, that the plan and general scope of the work have been well adapted to the wants of the community.

It is believed the present edition will be still more worthy the patronage of the public.

In the description of disease the author has aimed to be as clear as possible, and in the treatment all the new remedies of importance have been introduced, the dose has been carefully given, and great pains taken to make the whole clear and in-telligent.

It is confidently believed that the work will prove a valuable aid to the student, and a convenient and trustworthy family medical companion.

The author takes this opportunity of acknowledging his indebtedness to numerous eminent physicians in different parts of the country who have kindly offered suggestions and contributed important medical facts.

These suggestions and medical facts, it is believed have ma-terially increased the value of the work.
