Nos. 3, 5 and 6 of obsen\ 7th, were not isolated, because, 
though sick, their temperature remained normal. 
Then, finally, a higher degree of temperature does not allow 
to diagnosticate in a bovine, which had not been exposed to the 
virus of pleuro-pneumonia, the existence of that disease; it may 
at the utmost, render it suspicious. 
But the thermometer helps to show assuredly that a diseased 
animal having been exposed to the pneumonic virus , and whose 
temperature remains normal , is not affected with pleuro- 
pneumonia. 
I have mentioned already the three symptoms: diminution of 
appetite, of rumination, of lactation, which always accompany 
the increase of internal temperature. It is somewhat difficult to 
distinguish, at the first meal, an animal which eats less, in a stable 
where the food is not given separately to each animal; or diffi¬ 
cult to notice, at first sight, the animal whose rumination is di¬ 
minished ; it is always easy to see when the lactation is reduced. 
Whoever milks the animal, recognizes it easily. It is for me the 
symptom of pleuro-pneumonia, which will be observed at first, 
just as well as it would in other diseases. 
It arrives that milking decreases suddenly, and is reduced to 
one liter, or even less, after three or four days. But it is not 
always so: No. 4, observ. 8th, gave 10 liters the 17th of Novem¬ 
ber, 15 the 15th. Again, No. 1, observ. 5th, milked 18 liters 
the 27th of September, 12 the 29th, 17 the 7th of October, and 
then came down to 15, to 6 on the 18th, and was almost dry on 
the 19th. Still the temperature had varied but little. We can 
then conclude also that the diminution in the milk is not in pro¬ 
portion with the increase of temperature. 
But the diminution takes place in all diseases. It was dimin¬ 
ished in cow No. 8, observ. 8th, which had a swelling under the 
belly. Nos. 3, 6 and 5, of observ. 7th, had it also, as consequence 
of poor feeding. 
Shall I say a word of the horripilation. It shows nothing as 
far as pleuro-pneumonia goes. I have noticed it in healthy 
animals, tormented by flies. It has been such in some cases that 
while taking observations I often feared the existence of the lung
