The Practice of Medicine. A text-book for practitioners and students with special 
reference to diagnosis-and treatment. By James Tyson, M. D. Fourth 
edition, revised and enlarged, with 240 illustrations, including colored plates. 
Cl., pp. 1305. Price, $5.50 net. Philadelphia: P. Blakiston’s Son & Co. 
1906. 
On the whole Dr. Tyson has given us a splendid book and the value of 
this last addition is much enhanced by Dr. Smith’s excellent chapter 
on animal parasites and the conditions caused by them. 
Diabetes, typhoid fever and a number of other diseases of which the 
author has long been known as a careful student have received a most 
thorough and satisfying consideration. 
All discussions as to treatment are carefully revised and thorough; 
the positiveness with which drugs are recommended and the careful 
details for their administration will do much to retain fast-disappearing 
optimism in this branch of therapeutics. 
One is somewhat surprised that the paratyphoid fevers should receive 
such brief consideration and the discussion of some other diseases such 
as Malta fever, amcebic dysentery, dengue, and even malaria, is hardly 
satisfying, at least to those working with these infections in the Tropics. 
It would seem that the recent literature on smallpox, splenic anemia, 
splenomegalies in general, arterioschlerosis, and several other diseases is 
of sufficient importance to give more of it attention in a book of this 
character, revised as it is to 1906.

Nothnagel’s Encyclopedia of Practical Medicine: Malaria, Influenza, and Dengue. 
By Dr. Julius Mannaberg and Dr. O. Leichtenstern. Edited with additions 
by Major Ronald Ross, F. R. C. S., F. R. S., C. B.; J. W. W. Stephens, 
M. D., D. P. H., and Albert S. Griinbaum, M. D., F. R. C. P. Translated from 
the German under the editorial supervision of Alfred Stangel, M. D.—ClL., 
pp. 769. W. B. Saunders & Company, Philadelphia and London, 1905. 
The volume of Nothnagel’s Practice dealing with malaria, influenza, 
and dengue, is of peculiar interest to the student of tropical medicine 
by reason of the wide distribution and importance of the first of the 
diseases treated and because of the uncertainty of the nature and symp- 
tomatology of that disease so exclusively diagnosed in the Tropics, namely, 
dengue.
