The Story of Germ Life: Bacteria.

“Though a popular work, the Story of Germ Life, as told by Prof. H. W. Conn, is so admirable for its lucidity, terseness, and the author’s grasp of the subject, that it may be recommended to any one who is desirous of becoming acquainted with the general features of bacterial life and the baneful and beneficial results of microbic growth and development.”—Journal of Royal Microscopical Society.
