important a part in the operations, whether useful or destructive, of life; but books in which satisfactory accounts of them are given are as yet rare, and hardly accessible. The author of the present paper, who is Professor of Botany and Horticulture in the Illinois Industrial University, has prepared it with the object of presenting, in language as far as possible freed from technical terms, the principal and most interesting facts now known about these active agents. He also gives references to other sources of information on the subject.
