It would scarcely be possible to show a more striking contrast 
than is afforded by these temperature records, and they are 
an exact parallel of the symptoms observed. In order to avoid 
the error which might arise from a slight variation, the 
diurnal range for the preceding three months is given in each 
case, and also the average for the entire observations during that 
period. 
In the case of the heifer C, which had been inoculated success- 
fully three months before, there were practically no symptoms 
whatever. There will be seen to be a rise of temperature of 
less than 1° on the day succeeding the inoculation, and there 
was a small swelling at the seat of each injection, as might 
have been expected from so large a quantity of blood. At one of 
these points a small phlegmon subsequently formed, but gave 
rise to no trouble. 
In the heifer D, on the other hand, very severe symptoms were 
induced, more intense than in any of the other inoculations, 
and of such severity that the life of the animal was despaired of 
for two days. I ought here to observe that, had I been at the 
moment fully alive to the very small degree of protection which 
the animal had received, I should not have ventured on the
