In this experiment my hand warmed up while in my office. 
(c.) I have observed the increase of temperature, in placing 
the thermometer in the rectum of cow No. 4, observ. 5, the 26th 
of October. 
The heat of the stable was 20°, After one minute the instru¬ 
ment rose to 37°5 to 35°5 ; after two, to 37°6 ; after three and 
after four minutes, it registered the same. 
In cow No. 6, as the instrument is placed in the rectum it 
marked 30° ; after one minute it shows 35°6; 36°8 after two, 
37° 1 after three and four minutes. 
The 28th of October, the external heat was 13° 9. Placed in 
the rectum of cow No. 4, the instrument rises in one minute to 
34° ; to 36°4 in two ; to 36°9 in three ; to 37°4 in four ; and after 
live minutes, to 37° 6. 
Introduced in the rectum of cow No. 6, in six minutes the in¬ 
strument goes up to 37°2. 
These experiments prove that, in the hand, the thermometer 
rises slowly, somewhat fast in the mouth, very fast in the rectum, 
as in those, there is no loss of heat. 
Therefore, it requires live or six minutes (live according to 
Fleming), for the thermometer when in the rectum to reach the 
maximum of temperature; say 36 minutes to take the tempera¬ 
ture only in six animals; in supposing that the animal does not 
rebel against the examination and remains quiet. 
When I wrote the first part of this work, I did not think that 
the constatations of the temperature would ever be difficult or 
even impossible. 1st, on account of a peculiar nervous impression¬ 
ability; 2d, of the irritation produced by the flies; 3d, at the 
pain produced at the tail, by the swelling following the inocula¬ 
tion ; 4th, or on account of excessive warm weather. 
For instance, I have not been able to take it in Nos. 4 and 5, 
observ. 5. 
There are many errors in taking the temperature that one 
may commit. 
For instance, those inherent to the dilatations of the mercury, 
whether the length of the instrument or the bulb alone is intro¬ 
duced in the rectum.
