Micro-organisms of the Mouth.* — Dr. W. D. Miller has recently 
published the second edition of his work on the micro-organisms affect-

resulting therefrom. The present edition has been thoroughly revised 
and much enlarged : it contains 448 pages, and is illustrated by 134 
engravings and 18 photographs.
