They look at first sight like fine needle- shaped crystals, and their true nature can only be recog- nised by staining. They retain their colour when treated by Gram's method. Gelatine is not liquefied, and indis- tinctly defined colonies occur on the plate and spread out over it in the form of delicate whitish nebulosities.

Gelatine is not liquefied, and indis- tinctly defined colonies occur on the plate and spread out over it in the form of delicate whitish nebulosities. In thrust-cultures in like manner there appear bluish-grey turbid clouds, which permeate the entire gelatine (fig. 99).

Inoculation causes death in house- mice in two or three days, but field-mice and guinea-pigs are immune. The bacilli ure found in the vascular system, and the white corpuscles are often found to be totally destroyed. The blood of the dead animals proves very virulent. Spirochetse Obermeieri.—In recurrent fever Obermeier found spirilla in the blood at the time of the attack. They are about six times as long as the diameter of a red cor- puscle, and move in a very lively manner (fig. 100). They show themselves readily amenable to staining with the ordinary basic aniline dyes, but give up the colour again.
