CORRESPONDENCE. 
first of January to the first of March, when ten cows belonging to 
Wm. Young, whose lands adjoin those of G. Michael Freck, (an 
infected farm) broke out with the disease, five of which died. In 
this outbreak inoculation was resorted to, after which only four 
cases developed the disease, and these on the second day after the 
inoculation. Since then there have been no new cases. Just 
here let me state in answer to inquiries which I have received, 
that the cow which communicated the disease in question to Mr. 
Cramer’s herd is said to have come from Ohio, but that she did, 
or that she was not in New York City long enough to contract 
the disease there, seems to be past finding out. 
That this cow did introduce pleuro-pneumonia in that neighbor¬ 
hood there is no question, but that she became infected in Ohio is 
extremely doubtful. 
In my article on this same subject which appeared in the Jan¬ 
uary number of the He view, it was stated that some of the in¬ 
fected cattle “ recovered.” 
I did not intend to convey the idea that the disease is curable, 
but that cattle may sufficiently recover to return to their milk 
and lay on fat. 
I took it for granted that the profession was entirely satisfied 
as to its incurability, and hence the loose manner in which the 
word recover was used. In an essay which I read before 
the Pennsylvania State Board of Agriculture in May, 1877, 
on this subject, in speaking of the terminations—occurs 
the following : “ Health seems to be reestablished. I say 
seems to be restored ; for in almost every case of this 
kind we find, on a careful examination, more or less diseased 
condition of the lungs, which is present in a latent form, but only 
waits the proper stimulus to make it the nucleus of a contagion 
* 
which may infect whole neighborhoods and bring about all the 
terrible calamities resultant on such outbreaks,” and further on, 
“ Cattle once infected should not be kept for any purpose, but if 
kept should remain apart from all others until fat enough to kill, 
and be disposed of in this manner.” 
To veterinarians the most important point of all is, how shall 
we deal with an outbreak of pleuro-pneumonia ?
