mal. Death does not always occur when the temperature of the 
body is high, but sometimes after a sudden fall. 
A differential diagnosis between pleuritis and pneumonia by 
the thermometer does not appear to be possible, for Bayer ob¬ 
served much the same phenomena in the one as the other. In 
chronic pleuritic exudations, the temperature remains at about 
39°c. in the horse. 
In acute rheumatism of joints, C. Harms says the temperature 
is about 2° above the normal condition. 
When diseases of an inflammatory nature take on the healing 
process, the temperature slowly decreases about 1° in twelve or 
twenty-four hours; if, on the other hand, the temperature sudden¬ 
ly falls, as from collapse, the patient is in great danger, and in 
all probability will die. 
There is an increased temperature in all fevers , being a char¬ 
acteristic phenomena of fever, which also provides us with the 
best means of ascertaining its intensity. In human medicine, 
fever plays a very important part and is very exactly observed; 
owing to which the thermometer has become a valuable means of 
diagnosis. For instance, in cases where the symptoms are not de¬ 
veloped, or perhaps an uncomfortable feeling is the only symptom 
present, the pulse and other phenomena being little changed, the 
thermometer often proves very valuable in forming a diagnosis. 
This stage of the disease, however, is seldom noticed in our domes¬ 
tic animals. 
Cl. Bernard, after whom Leyden, Traube and Liebermeister 
proved that the increased warmth was the principal symptom of 
fever as the old name fire or felvis (from fevere-to boil) or pyrex¬ 
ia (fire) long ago indicated, as did Galen when he spoke of the 
color prcetor naturam. In fevers, where extraordinary heat is 
suddenly generated, the temperature rises very fast, as we may 
sometimes see an increase of 4° within an hour; the decrease 
however often follows just as quickly. In the fever-shiver, and 
even before, an increase may be detected long before any alter¬ 
ation can be found in the pulse. During the state of fever the 
temperature always remains high, therefore the loss of heat is 
greater; and if the disease decreases in intensity, or the animal
