ion results, seems to leave no doubt that the infection was in no 
y due to extraneous contamination. It must be remembered 
hat at the time of the autopsy we came to the conclusion that 
he case was not one of tuberculosis, and, therefore, no further 
onfirmation was sought. 
The fact that two separate cases of tuberculosis in unusual 
>calities in this herd occurred within a year, seems to indicate 
Dme unusual source of infection. None of the farm hands had 
iberculosis, as far as could be learned. Possibly the infection 
lay have been accomplished through the agency of some smaller 
limals, rodents for instance, about the farm, in whom tubercu- 
sis would not be suspected. 
The fact that no subsequent cases appeared in the herd this 
iar points to some transient source of infection of an unusual 
laracter.
