A NEW WORK 
By GEORGE M. NILES, M.D. 
This is a hook you must have to get in touch with the latest 
advances concerning this disease. It is the first book on the sub- 
ject by an American author, and the first in any language ade- 
quately covering diagnosis and treatment. All etiologic theories 
are impartially discussed. Pathology, heretofore an echo of 
European views only, is here presented from an American point 
of view as well, much original work being included.

on the origin of life and its manifestations, the cell and cell 
division, reproduction. ontogenesis, conformity to type, divergence, 
structural and blood relationship, parasitism, mutilation and re- 
generation, grafting, senescence, etc. For the worker in this 
field this book is most valuable.
