    or disease-inducing to the higher animals, when they have passed through the blood of the lower forms of life, such as Ticks, and have been transmitted by these into the circulation of the higher animals. This view to some extent supports that of Buchner, who states that the ordinary Hay Bacillus—Bacillus suUilis—attains all the virulent properties of the Bacillus anthracis after it has been cultivated in animal media, meat- extract, blood, &c. Since this work has gone to press, the Author has received farther corroboration of the seemingly anomalous occurrence of simple filaments as retrogressive stages in the development of an organism, apparently dependent upon a change in the nutrient medium,—a fact previously noticed in the course of his Louping-Ill investigations, 1882, which has led to a consider- able amount of controversy. These so-called involution stages, as exhibited by the Bacillus typhosus, will be found described and illustrated in a paper by Dr. Edward P. Carter in the Bxdlctin of the Johns Hophins Hospital for June of this year. The thanks of the Author are specially due to his colleague Dr. James Hunter, whose unwearied labours and whose acute judgment and profound learning have contributed greatly to the fulness and accuracy of many of the illustrations, in them- selves unique, in the present work.
