Bone Marrow in Tularaemia

Bone marrow in animals dead of tularaemia has been under observation in our laboratory since May 11, 1929, during which time we have studied the maxrow of the femur in the following animals infected in the laboratory: Blacktailed jackrabbit, Lepus; Cottontail rabbit, Sylvilagus ftoridanug; Belgian hare, Oryctolagus cuniculus (domesticated); Guinea pig, Cavia cobaya; California ground squirrel, Otospermophiluw grammurus beecheyi; Cotton rat, Sigmodon hispidu*. The present article does not consider the lesions of tularaemia in organs other than marrow except for an occasional reference for purposes of comparison.
