MRS. FRANKLAND has compiled an interesting, instructive, and accurate account of the modern developments of bacteriology. Such subjects as sewage disposal, the prevention of tuberculosis, micro-organisms in milk, air, and foods, which are of public importance, are fully dealt with, and the modern ideas regarding toxins and antitoxins are briefly discussed. No one nowadays laying claim to a liberal education can dispense with a slight knowledge, at least, of microbes and their actions, and for such this work will prove an adequate text-book. Bacteria in Daily Life. By Mrs. Percy Frankland. Pp. 216. (London: Longmans, Green and Co., 1903.) Price 5s. net.
