Iii these five animals the diagnosis could he made without the 
thermometer, as the disease was at the period of acme. All were 
killed. 
I observed the following temperatures : 
1st. 38°5 in cow No. 1, 2nd observation, killed by my order. 
2nd. 38°3, raised to 40° in two days by cow No. 4, Sth obser¬ 
vation, slaughtered. I did not make out pleuro-pncumonia, the 
18th and 19th when the temperature was 38°3, but was suspected 
on the 20th, the thermometer registering 40°. 
3d. 38°8 August 30th, thermometer raised to 40°8 Oct. 1st, 
(No. 6, 3d observation). Killed by my order. 
4th. 38°9 August 12th, temperature raised to 40°T and down 
again to 38°9 (No. 1, 3d observation). Animal got well. 
5th. 38°9 the 3d of Nov. (No. 10, 8th observation). This cow, 
which had been sick but one day, and in which I did not suspect 
pleuro-pneumonia, was killed, and exhibited hepatization of her 
lungs. 
6th. 39°3 the 16th of Nov. (No. 1,10th observation), was visi¬ 
ted only when in convalescence. 
7th. 39° the 4th of Aug. (No. 3, 5th observation). Disease 
far advanced. Animal killed by order. 
Sth. 39°5 the 20th of Nov. (12th observation). Slaughtered the 
23d. 
9th. 39°5 the 14th of August; later rising to 41°2. Killed by 
order. 
10th. 39°8 the 19th of October (No. 2, 6th observation). The 
temperature came down to 39°6. Destroyed by order. 
Consequently, the periods of invasion and of increase are ac¬ 
companied with a rise in temperature to 41°. 
To define exactly these two periods, is difficult. It seems to 
be 40° for the period of invasion and 41° for that of increase. 
The period of invasion is not easy to recognize, the symptoms 
observed can belong to other diseases, especially to indiges¬ 
tion. The period of invasion was observed at post-mortem in No. 
10, 8th observation, and No. 1, 12th observation, and also by the 
continuation of the disease in No. 4, 8th observation. Killed the 
20th.
