Agricultural Bacteriology by FI. W. Conn, published by 
P. Blakiston’s Son & Co., pp. 1-412, 1901, is a study of the rela¬ 
tion of bacteria to agriculture with special reference to bacteria in 
the soil, in water in the dairy, in miscellaneous farm products and 
in plants and domestic animals. The author does not attempt to 
confine himself strictly to bacteriology — as for instance he says 
“it has been a growing conviction that a considerable number of 
phenomena, hitherto attributed to Bacteria, are directly due to a 
class of chemical ferments called enzymes.” These are not there¬ 
fore excluded from consideration in this book. In Part V para¬ 
sitic bacteria are considered and the species causing some of the 
common diseases are considered. It is an admirable book for 
students and for general readers.

The treatment of our species is similar in plan to that followed in 
the author’s previous articles. New names are Bjerkandera fra- 
grans (for Polyporus fragrans Peck), Trametes unicolor (for 
P. unicolor Fr., and P. obtusus Berk,), Coriolus hirsutulus (for
