1899] CURRENT LITERATURE 327 
Bacteriology has encouraged the author to prepare the fourth edition, which 
isa thorough revision of the third. The work is divided into three parts ; 
first, the structure, form, physiology and methods of study of bacteria in 
general; second, the contamination and fermentation of milk, and the proper 
means of milk preservation ; third, the relation of bacteria to milk products, 
4s concerns both their desirable and undesirable effects. 
The work is excellent in that it makes practical application of so much of 
the purely scientific work of bacteriology. It furnishes a further testimony 
to the mutual relation existing between research and practice. It seems, 
however, that the book should contain figures of those bacteria found in con- 
nection with dairying, which induce not only unfavorable conditions in milk, 
but also of those which induce diseases of men, since illustrations would 
better enable students of dairying to identify such organisms when present. 
It is quite noticeable that so important a work as the Manual of Bacteriology 
by Muir and Ritchie should be omitted from the author's list of works which 
“contain more or less complete descriptions of the various processes 
‘mployed in studying bacteriology.” 
As a text upon dairy bacteriology the book fills a place not approached 
by any other work, as shown by the fact that it is now used in all the dairy 
schools of the United States and Canada. In addition to the interest in the 
book on the part of students of such schools, the subject is of so much impor- 
— toall users of milk and its products, and the book is so excellently written 
that it should be extensively recommended to all as a study in public hygiene.
