633 where the species are described it is said to be non-motile. The 
same for Bacillus fulvus, which p. 758, is said to be motile, but on p. 629 
is described as non-motile. Notwithstanding that a few of these defects 
. occur, this part will certainly be appreciated by working bacteriolo- 
gists. In this key the following characters are used. (1) Morphologic; 
Micrococci, Bacilli, Spirilla, Leptotricheze and Cladotrichee. Forma- 
tion of spores, independent motion. (2) Physiological characters ; 
relation to oxygen, xrobic, strictly anwrobic, facultative anzrobic, 
growth in gelatin, liquefy or do not, no growth in gelatin, growth on 
potato, in milk, coagulate milk, do not coagulate milk, color of growth, 
chromogenes, not chromogenic, pathogenesis. 
The bibliography has been gotten together with great care, and is 
very full, containing the titles of 2,582 papers grouped under historical 
classification, staining methods, culture media, sterilization of culture 
media, etc. A very large number of papers are cited on the physiolog- 
ical properties, such as lactic acid fermentation, viscous fermentation, 
putrefaction, ete. The literature on pathogenic microorganisms is, 
especially full. Bacteriologists should feel grateful to Dr. Sternberg 
for this work, and also to the publishers for the excellent manner in 
which their part also has been performed. 
Wm. Wood & Co. have during the past four years issued two other 
text books on bacteriology; the English translation of Salomonsen’s 
Bacteriological Technology, by Professor Trelease is well known and 
needs no introduction. A second admirable work, antedating Stern- 
berg’s Manual, is Frinkel’s Grundriss der Bakterienkunde translated 
by J. H. Linsley.? It has been translated into six different languages, 
and those who have been fortunate enough to use the German edition 
know its admirable qualities. The translation before us is an admir- 
able one. The style is clear and there is no difficulty in understanding 
the author. The work contains a great deal on the biology of many 
species that hitherto has not been found its way into English works. 
It is to be regretted however that references to literature are not given, 
but these may readily be obtained from Sternberg’s Manual. No 
figures are given in the book, but the accounts are clear. Future 
editions should have figures. 
For a limited amount of work both of the books noticed above are 
too large. One of the best of the small books with which the writer 1s 
familiar is Abbott’s? Principles of Bacteriology.
