THERMOMETRY IN CONTAGIOUS PLEURO-PNEUMONIA. 137 
I say probably, for the high temperature may indicate the invasion 
of another febrile disease. 
Of course these conclusions are somewhat incomplete. 
This part of my paper was submitted to the Academy of 
Medecine in June, 1876, and it was plain, in reading it, that I 
was a partisan of thermometry as means of diagnosis of pleuro¬ 
pneumonia, in bovines which had been exposed to the contagion 
but presented as yet no other symptoms. 
It is in Mr. Brown’s reports to the Privy Council that the 
use of this means of diagnosis is recommended, and in a circular 
of the sixteenth of January, 1874, that it is indicated as already 
reported.* * * 
This measure was so severe and important that I took the 
resolution to experiment on the means of diagnosis thereto indi¬ 
cated. 
First, I will observe that a weekly visit is insufficient; visits 
must be more frequent, if one desires to protect healthy animals 
from contagion. Before relating my numerous observations, I 
may present some notes found amongst my journals. 
Mr. Fleming, editor of the Veterinary Journal , advises to 
introduce the instrument in the rectum to a depth of one deci¬ 
meter, and to leave it about five minutes. In the vagina he has 
observed a difference of less than 0.2° to 0.5°, a difference, which, 
according to Gerlach, is about 1°. Mr. Fleming found also a 
difference between the morning and the evening, or after exercise. 
He gives for normal temperature, 38.5° for the bull, 39.25° for 
the cow, 39.5° for the calf. The Veterinarian of 1869 publishes 
an article from Dr. Richardson, which fixes the temperature in the 
ox to 101° Fah. He says that an increase of the temperature of 
a warm blooded animal is fatal at 11° or 12° Fall., and that lie 
never saw a case of recovery after an increase of 12°. In this 
paper, no more than in that of Mr. Fleming, it is not a question of 
plenro-pneumonia. In the same journal, in 1870, two other 
articles on the same subject are found. 
In the first is reproduced an article from Mr. Mayor. The 
observations reported are on the horse, and speak of the effects of 
“June number American Veterinary Review, p. 108.
