160 THE AMERICAN MONTHLY. [ August. 
them. Virchow it was who inaugurated this new method and established it on a firm 
basis.” We may see in this the key-note to the treatment followed throughout the work. 
Preceding each section is a chapter of general considerations wherein a most convenient 
summary of the subject in hand is spread before the reader. This summary, with 
later explication of the subject in the remaining chapters of each section, is analytical 
throughout, and the book is thus made an analytical key wherein may be found in its 
proper place the consideration of any subject. 
In treating each subject the author states the facts with discussion of mooted points, 
and cites numerous articles furnishing thus a valuable resumé of the literature on each 
topic. In the review and discussion of this literature the work is brought down to in- 
clude very recent articles in many cases, even so late as 1886. This makes the work 
extremely valuable for students’ use, both by reason of the review of the discussion, 
and the key to the original articles. The list of authors cited contains the names of 
about 1,400 writers; among them Virchow is yeferred to 117 times, Wagner, Weigort, 
-Rindfleisch, Ranvier, Klein, Klebs, Koch, Eberth, Cohuheim, Cornil, and many 
others are often referred to frequently at considerable length. 
As iNustrating the character of treatment more clearly, let us select the section (vi) 
on tumors. Ina chapter of general considerations, taking up the mode of tissue for- 
mation in a tumor growth, with a brief discussion of the use of the word ‘tumor’ 
and references; discussion of the various names for various kind of tumors, the 
clinical character of tumors. The following chapter on mesoblastic or connective 
tissue tumors, considers a, fibroma; 6, myxoma; ¢, lipoma; d, glioma; e, chond- 
roma; /f, osteoma; g, angioma; 4, myoma; z,neuroma ; 7, lymphoma; 4, sarkoma; 
Z, mixed tumors. The third chapter treats of epithelial tumors, glandular, and cancer 
of the various forms. The second and third chapters are well illustrated (37 figures), 
and there is an abundant reference to and discussion of unsettled matters. The fourth 
chapter of the section, the etiology of tumors, discusses pretty fully the views as to 
the nature of tumor and cancer, the origin of cancer, etc. The section covers 71 
pages, and there is considerable scattered through the special pathology part of the 
book besides, making a very thorough though brief treatment of the topic. 
The make up of the work is most commendable; the type is clear, and the intro- 
duction of heavy-faced type at the head, or in the middle of sentences whenever the * 
chief word occurs, makes it easy to learn the subject matter of each paragraph at a 
glance. The index of subjects is very complete, occupying 26 pages, double columns. 
The illustrations are not what lithographs, or even the best photo-engraved plates, on 
plate paper can furnish ; some are actually poor, but the vast majority of the figures 
are excellent. All the figures are made most available by the unusually complete and 
clear system of explanation by reference letters on the drawing and explanatory table 
immediately beneath. A brief epitome of the histological history of the section from 
which the drawing is made is also given in every instance,
