animal had better be slaughtered. In like manner should she be 
treated when the exudate extends to the genito urinary organs. 
“ Males, young stock and calves, I find from experience, can 
be inoculated with little or no risk. This is a very important fact; 
for should inoculation ever become general in the country, the 
necessity for doing it upon our home-bred stock when brought 
into dairies would be obviated by their being done at an early 
period of their life, when the operation, while being equally pro¬ 
tective, is attended with little or no risk, and does not call for any 
after attention. 
“ I have nothing to say on the subject of diet while animals 
are under the operation. It only requires to be rather below than

give any opening medicine, the purpose will be fully and efficiently

“ This, of course, is with the view of lessening any attendant 
fever. I have not, however, found that there ever is much, the 
thermometer rarely rising above 102° F.” 
The above remarks do not include Mr. R’s experience for 1879; 
this is found in the following answers to queries addressed to him 
by Mr. George Fleming: 
1st.—Have any of your inoculated animals yet become affected 
with pleuro-pneumonia ?—Answer, None. 
2d. Have you tried inoculation on any animals but those of 
the bovine species ?—Answer, I have not. 
3d. Will animals once successfully inoculated take the inocu¬ 
lation as markedly as the first ?—Answer, They will not. 
4th. What is now your average mortality?—Answer, One per 
cent. 
Here, then, we have the means of successfully applying this 
prophylactic measure, and the results of the operation fully set 
forth by the most successful operator living. He says:* “So cer-
