2. The wads of the Peters Company, inoculated in rats, guinea- 
pigs, and rabbits, produced characteristic symptoms of tetanus. 
3. The powder of the three varieties of cartridges examined was 
negative for B. tetani and B. aero genes capsidatus.

animal experiments, that the wads of certain blank cartridges 
contain B. tetani. Dr. Welsh told me that he considered it 
diagnostic to see an animal in convulsions.
