one case, which recovered, the temperature never exceeded 39.3°. 
Siedamgrotzky noticed in a tetanic dog, which recovered, the 
temperature to be about normal, 38.4°, at the commencement of 
the disease. On the fourth day it fell below the normal, viz., to 
37.3°, and gradually returned again to the original temperature 
from the fifth to the eighth dav. 
In the nervous form of febris catarrhalis epizootica canum (dis¬ 
temper), the temperature is generally low, and in chorea , it is 
generally subnormal; the same is observed in eclampsia. During 
violent cramps, however, the temperature is increased to 39° and 
even 40°. By the phenomenon of depression a decrease in the 
temperature to 35° was noticed by Siedamgrotzky, in a fatal case 
of distemper caninus. 
I have used the thermometer to diagnose the different kinds 
of colic in horses. For instance, to distinguish an inflammation of 
the intestines (enteritis) or inflammatory colic, in which venesec¬ 
tion is necessary, from the non-inflammatory, which are generally 
due to congestion, and states of the blood caused by emboli in the 
arteria mesenterica anterior, and also from paralysis of the intes¬ 
tines, in which case irritating agents are useful. In the first case 
we find the temperature rises to 40°, whilst in the last it sinks to 
37° and even to 36°, and if a sudden increase takes place in the 
last instance, it is a sign that mortification has set in. Bayer says 
that no correct idea of the temperature can be obtained in colic, 
from the fact that the clysters act as a local means of cooling the 
rectum and vagina. Adam has observed a temperature of 39.6° 
in vagina during enteritis. 
Strangulated hernia and invagination of the intestines are 
always accompanied by a low temperature, and the more extensive 
the incarceration is, the more marked is the decrease of the bod¬ 
ily temperature. 
It was above remarked, at the commencement of this paper, 
that fever and temperature go hand in hand together during dis¬ 
ease, and that they form the initial phenomena. They are due to 
the local changes caused by alterations in the action of the nerves, 
which is followed by an increased consumption of the tissues. 
It has been proved by Liebermeister that the co 2 increased with
