Bacteriology; Pathogenic bacteria; Protozoa. 670 Bacillus Murium mice that had eaten the bread, but also infected others that ate their dead bodies, the extermination progressing until scarcely a mouse remained. In discussing the practical employment of this bacillus for the satisfactory de- struction of field-mice, Brunner* calls attention to certain conditions that are requisite: (i) It is necessary, first of all, to attack extensive areas of the invaded territory, and not to attempt to destroy the mice of a small field into which an indefinite number of fresh animals may immediately come from surrounding fields. The country people, who are the sufferers, should combine their efforts so as to extend the benefits widely. (2) The preparation of the cultures is a matter of importance. Agar-agar cultures are most readily transportable. They are broken up in water, well stirred, and the liquid poured upon a large number of small pieces of broken bread. These are then distributed over the ground with care, being dropped into the fresh mouse-holes, and pushed sufficiently far in to escape the effects of sunlight upon the bacilli. Attention should be paid to holes - in walls, under railway tracks, etc., and other places where mice live in greater freedom from disturbance than in the fields. (3) The destruction of the mice should be attempted only at a time of the year when their natural food is not. Fig. 264.—Bacillus typhi murium (Migula). plenty. By observing these precautions the mice can be eradicated in from eight to twelve days. In the course of two years no less than 250,000 cultures were distributed from the Bacteriological Laboratory of the Tierarznei Institut in Vienna, for the purpose of destrojdng field-mice. The bacilli are not pathogenic for animals, such as the fox, weasel, ferret, etc., that feed upon the mice, do not affect man in any way, and so seem to occ
