to one side. The power to back was completely lost. If the 
animal, were left to himself he would wander about in a list¬ 
less, aimless manner, or stand for a long time, with head 
c rooped, in a sort of stupor. The mucous membranes were ex¬ 
ceedingly pale. When it was desirous to lead him, we found 
it to be impossible. When the rope was thrown on to him, 
ne reared backward, and it was impossible to get him to move 
forward. In the attempt to lead him, he fell. I killed him by 
opening the jugular vein. 
POST MORTEM CONDITIONS. 
The organs in the abdomial cavity were in the following 
conditions : 7 he stomach was empty, except a small quan¬ 
tity of partially chewed grass and weeds, and a small amount 
o sand and dirt. The small intestines and caecum were in a 
normal condition, except that the coats appeared thinner 
than they should, and the muscular coat was flabby and re¬ 
laxed. I he colon was enormously distended with food, that 
was undigested and presented a partially chewed appearance. 
he spleen was. somewhat shrunken and much more dense 
than normal; kidneys were normal; the liver was consider¬ 
ably shrunken and hardened, and extremely adherent to 
the capsule. The capsule of the liver showed numerous spots 
o moie or less perfectly organized lymph. The liver pulp, 
granular and friable.. 
NERVOUS SYSTEM. 
The spinal cord was softened considerably throughout the 
greater portion of its extent. 
The cerebral hemispheres of the brain appeared normal, 
except a slight congestion and fibrous hardening of the arach¬ 
noid membrane, 7 he middle ventricles were almost filled 
w ith serum of a yellowish color. The fourth or cerebellar 
ventricle was filled with a hemorrhagic effusion, the whole 
base of the cerebellum being covered with a blood-clot, more 
or less organized, and a large quantity (three fluid ounces) of 
sei um bathing the base of the brain, and the medulla oblon¬ 
gata. The hemorrhagic effusion, or blood-clot, completely 
covered the base of the brain, floating in this serum, as well 
as the fourth ventricle, and was held to the brain substance 
1 organized tough fibers and also to the meninges of 
the brain. The blood was deficient in fibrine, only, imper¬ 
fectly coagulating. All of the serous cavities had an abnor¬ 
mal quantity of serum in them. 7 he second case was a brown 
three-yeai-old gelding. The colt showed all the symptoms of 
the other case, except that he was stronger, and, if possible,
