THERMOMETRY IN CONTAGIOUS PLEURO-PNEUMONIA.

that, where the animal is not out to pasture, the thermometer 
will register 103° or 104° Fah. In this state there will be also 
anxiety, cough, the skin will be shying. But all well considered, 
there will be signs of elevation of temperature due to an inflam¬ 
matory condition, having its seat in the thoracic cavity. When 
the thermometrical examination is made on the first day, it is 
found that 104°, 105° Fah. is often registered ; according to the 
intensity of the attack, the time where the visit is made, the age 
of the animal, whether the animal is in or out of doors, whether 
it is in winter or in summer. From that time to the complete 
development of the disease the temperature increases daily so as 
to reach 107°, 108° Fah. in the vagina, or even 109° in the rec¬ 
tum. I will add that, as maximum of temperature, I have ob¬ 
tained 107° Fah. in the vagina, and have seldom seen animals in 
these conditions recover. 
“ In the sporadic form of pleuro-pneumonia, in gastro-bron- 
chitis, in pneumonia, bronchitis, pleuresy, gastritis, gastro-enteritis, 
and similar diseases, though the temperature may be very high, 
I never found a temperature above 104°, 105° Fah. in the vagina. 
Consequently, no matter how alarming the symptoms may be, if 
the temperature does not go above 105° Fah. it is easy to conclude 
that there is no pleuro-pneumonia present. As soon as there is a 
noticeable lowering in the temperature, it may be presumed that 
the period of increase is ended ; the whole organism is infected, 
there is a kind of rest in the vital activity. If the economy is 
not too much exhausted, and the organic alterations not too ad¬ 
vanced, nature tends to a restoration; if not, the vitality dimin¬ 
ishes, the molecular inertic prevails and the animal ends in suc¬ 
cumbing. In both cases there is a gradual diminution of temper¬ 
ature, not as rapid however when there is a return to health as 
when the disease has a tendency to fatal termination. In cases 
of recovery, as soon as the vital power is somewhat restored, 
nature begins to rid itself, by excretion, of the products of the 
disease; excretion which, I think, continues for three months. 
It is then that, in my opinion, there is danger; it is then the 
period of infection, of contamination par excellence .”
