Chemical Pathology. By H. Gideon Wells,
Philadelphia, W. B. Saunders Co.
While only a comparatively short time has
elapsed since the appearance of Virchow's
" Cellular Pathology," yet it is significant oi

tions, Normal and pathological processes as
well as bacterial influences in their relation
to higher forms present so many problems
that can be solved only by chemical agencies
