ally falls heavily to the ground whilst endeavoring to lie down. 
As a result there is bruising and laceration of the knees, fet¬ 
locks, etc. The paroxysms in the case of a mule lasted from 
four to six hours ; in the case of two horses twenty to twenty- 
four. When endeavoring to walk, which they do only on 
rare occasions, there is marked incorordination of movement. 
In some cases there is slight discharge from the nostrils and in 
all cases more or less oedema under the belly and of the legs, 
especially after a few days 5 sickness. Palpitation of the heart 
and paleness of the mucous membranes are constant symptoms. 
The treatment in the case of two troop horses which were 
under my charge consisted of placing the animals in slings, 
good nourishing food, and the administration of quinia sulphate 
and iron twice each day, with an occasional laxative of oil and 
calomel. The animals recovered after an illness of ten and 
twelve weeks respectively. 
A mule suffering from “ surra ” was given a purgative of 
aloes and calomel and put on an arsenical treatment, but con¬ 
tinued to get worse, until finally it was unable to assume a 
standing position, and in falling down when trying to rise had 
exposed the bones of the knees, so was shot to relieve further 
suffering. To the last minute this animal had a ravenous appetite. 
The chief signs after death were as follows: An abundant 
frothy discharge from the nostrils, under portion of chest and 
belly cedematous, conjunctiva ulcerated; tissues extremely pale 
and infiltrated with a yellowish fluid ; muscular organs friable. 
Peritoneum and pleural cavities contained a considerable quan¬ 
tity of fluid and a number of worms, most probably tli <tfilana 
papillosa. Stomach and intestines normal in appearance, but 
contained a quantity of dark brown foul smelling liquid. Liver 
reddish-yellow and very friable; kidneys palish and a small 
quantity of pus in the pelvis of the left one. Spleen slightly 
swollen, but of normal consistency. Bladder normal, contain¬ 
ing urine, which was fouud to be loaded with albumen. Lungs 
slightly congested. Heart palish, but normal in consistency. 
Brain and cord apparently normal.
