Friedlander Bacillus Bacteremia 411 



ly suggested the Friedlander group. Capsule stain from the 

 subculture was negative but intraperitoneal inoculation in the 

 white mouse yielded typical capsulated bacilli. The mouse was 

 very ill when killed at the end of 18 hours. Gelatin was not 

 fluidified. The organism was definitely a member of the Fried- 

 lander group. As the only physical finding suggested the pos- 

 sibility of a lung lesion the isolation of the bacillus pointed to 

 that region as the most likely diseased area. The X-ray exam- 

 ination on March 26 showed marked density of the right upper 

 chest from the second to the sixth rib. On March 30 this density 

 had decreased to a mere cloudy appearance. 



After a most stormy career for six days during which time 

 the temperature reached 106.8°F., there was a rather sudden 

 change for the better and the patient made a rapid recovery.

Thyroparathyroidectomy in the rabbit.

In reviewing the literature on the parathyroids, one is struck 

 by the lack of agreement in the results obtained by different ex- 

 perimenters following complete removal of the glands, in animals 

 of the same species. For example, Gley, in 1892, when he re- 

 discovered the parathyroids, in his first series of experiments on 

 rabbits, removed the thyroid and parathyroids from sixteen 

 animals. In fourteen of these acute symptoms developed very 

 rapidly and death followed within a day or two. In the same 

 year Moussu repeated Gley's experiment on rabbits and of the 

 eleven individuals on which he performed the complete operation 

 not one showed the acute tetany described by Gley. 



In late August and early September 1920, the writer thyro- 

 parathyroidectomized seventeen half-grown rabbits, keeping six 

 of the same litters as controls. Of the seventeen, one died within
