ZOOLOGY AND BOTANY, MICROSCOPY, ETC.

Micrococci forty-six are described, and among them aro figured some 
species of Sarcina. Nine spirilla and twenty-one pathogenic bacteria are 
mentioned. With regard to Crenothrix , Beggiatoa , and Cladothrix , the 
old views controverted by Winogradsky about pleomorpbism are still 
upheld. That writer’s work on the sulphur bacteria appears to be quite 
unknown to the author, for Beggiatoa is full of contradictions throughout 
and it decomposes sulphur compounds with development of sulphuretted 
hydrogen. 
Kitt’s Bacteriology and Pathological Microscopy.* * * § — Dr. Th. Kitt 
has published the second edition of his c Bacteriology and Morbid 
Histology,’ with an alteration of title. The work is intended for the 
use of veterinary surgeons and students ; it is a text-book, in fact, but 
of a superior kind, and well adapted to the wants of those to whom it is 
addressed. The illustrations are numerous, and superior to those of the 
first edition. 
Gedoelst’s Bacteriology for Veterinary Surgeons.f — This book, 
which deals with the diseases of animals from a bacteriological stand- 
point, is intended chiefly for veterinarians, though much of it will be 
found useful to those occupied with human pathology. The first portion 
of the work is occupied with micro-biology, immunity, and other general 
questions ; the second section deals with the bacteriology of separate 
diseases ; and the third portion deals with bacteriological technique. 
Gunther’s Bacteriology.J — Dr. C. Gunther has just published the 
third edition of his ‘ Introduction to the Study of Bacteriology and 
Microscopical Technique.’ The work, which has been revised through- 
out, is much enlarged and brought up to date. 
Friedlander’s Microscopical Technique^ — The fifth edition of 
Friedlander’s ‘ Microscopical Technique ’ has just been brought out by 
Prof. 0. J. Eberth. The present edition is intended not only for 
beginners, but also for experienced histologists. The whole work has 
been thoroughly revised, and the most recent methods of researches are 
given in their appropriate places. Special attention has been devoted 
to the examination of the central nervous system, the demonstration of 
micro-organisms in tissues, and to photomicrography. 
Von Kahlden’s Microscopical Technique. || — The third edition of 
Von Kahlden’s Technique for the Histological Examination of Patho- 
logico-Anatomical Preparations has been improved, and enlarged to 
122 pages. Special attention has been paid to the chapters on staining 
bacteria, the skin and the central nervous system, and to that on the 
examination of the blood. In the last chapter the examination of blood- 
spots, hairs, seminal fluid, and fragments of decidua are described.
