one side so as to have it press against the side of bow- 
els, allow it to remain from 3 to 5 minutes, remove carefully 
and note any deviation from the normal. The normal tem- 
erature of the horse is from 99° to 100°. In severe cases 
_ the temperature should be taken every 4 to 6 hours, while 
| in mild cases once or twice per day is sufficient. The tem- 
perature may sometimes run as low as 78 1-2° and the 
horse will servive, but when it reaches 75° it ismy judg- 
ment that death is rapidly approaching. 
RESPIRATION. 
In health the horse breaths from 12 to 14 times per min- 
_ ute, work or excitement increases this, however. The num- 
_ ber of respirations per minute can be readily counted by 
the heaving of the flanks. It requires no especial skill to 
_ distinguish the soft rustling sound of the healthy respira- 
tory murmur, but considerab'e experience is required to 
make one a first-class judge of the sounds obtained by per- 
cussion. Percussion is the act of striking smartly a finger 
of one hand,(resting gently over part to be examined) with 
the first three fingers of the other. In connection with the 
respiratory organs we place the finger over the lung in the 
region of the 6th rib, do our striking and. in case of health 
we find a clear resonant sound, but should disease exist 
everything is changed, depending entirely upon the nature 
and extent of the trouble. The abnormal sounds which 
prevail in diseases of the air passages and lungi will be 
treated under the heads of the various diseases with which 
they are associated.
