Since the discovery by Auer,1 in 1906, of certain rodlike bodies in the red blood cells in a case of acute leukemia, several additional articles have appeared, dealing with the character of these bodies and the type of cell in which they are found. Inasmuch as the literature on the subject is still meager, the report of an additional case may be of some value. The case is of special interest since it is the first, as far as can be ascertained, in which the Auer bodies have been demonstrated in microscopic sections of the various organs.
A résumé of the literature reveals little that was not described in Auer's report. Auer noted that rod-shaped bodies were visible as refractive objects in the cytoplasm of from 6 to 10 per cent. of the "large lymphocytes," in preparations of fresh blood; that they were stained clearly (red) by Wright's and Leishman's
