170 THEORY AND PRACTICE 



The next two cases were under Dr. Schneider's observaiion. 



Case No. 1 — Gray. Case No. 2 — Eoan. 



The first case developed a swelling 4 by 5. 



Second case developed a swelling 3 by 4. 



Both of these cases showed great depression the day f^iHow- 

 ing the injection and the next day also. It was decided that 

 they had the disease and they were destroyed.

 The irregular course used to be a disease called Bastard Strangles,

 glands and lymphatic vessels about the head. It runs a course

Inoculation with pus from these abscesses will not always
