ANIMAL PATHOLOGY. 
the pleural covering, resembling those which are sometimes seen 
in the dog : in this case, the fauces were also inflamed. The 
heart and larger bloodvessels are usually in a normal state; but 
occasionally little spots of ecchymosis have been seen on the sur¬ 
face of the heart, indicating, not the nature of the disease, but 
the degree of inflammation of the pericardic covering. 
The oesophagus is mostly free from inflammation. The paunch and 
reticulum are frequently filled with half-masticated food, mingled 
with sticks and stones, and various kinds of indigestible substances, 
from which proceeds a most noisome and putrid stench. There is 
frequently a great quantity of wool and hair in the paunch. Gene¬ 
rally there are patches of inflammation on the cuticular membrane 
of these stomachs ; but in a great many instances there is not 
the slightest blush of it. The third and fourth stomachs rarely 
present any morbid appearance, and are generally empty, or nearly 
so. In a few cases, inflammation of the mucous membrane of 
the rectum has been found : this has been probably accidental. 
In the greater number of cases nothing is observed indicative of 
rabies in any part of the intestinal canal. 
There is generally some injection of the pia-mater and arach¬ 
noid membrane. The substance of the brain is also injected, and 
they are principally the arterial vessels that are affected. This 
is particularly evident in the grey substance of the brain, and 
in which there is also a slight tendency to ramollUsement; but 
the medullary substance is rarely affected. In the spinal cord the 
lesions are certainly more decisive. Almost at the commence¬ 
ment of it the grey substance assumes a peculiar colour : it is 
somewhat approaching to lilac. The tint is faint in the cervical 
portion of the cord, but before we arrive at the lumbar portion it 
is distinct enough ; and there are strise, of inflamed substance, 
and the evident injection of numerous minute vessels. This por¬ 
tion of the cord is also perceptibly softened. All this was 
sufficiently plain in the sheep which I examined ; and Professors 
Vatel and Yvart have constantly found it; but, after all, it only 
proves that, in the sheep, rabies is accompanied by considerable 
inflammation of the spinal cord, and particularly of the grey 
portions of it. 
In Swine .—I am ashamed to say that we are indebted to a 
human surgeon for the greater part of what we know of the post¬ 
mortem appearances of rabies in the pig. I only wish that he 
had been candid enough to acknowledge his obligations to the 
first veterinary surgeon who devoted himself to the consideration 
of this disease, and by whom it was most admirably illustrated— 
I mean Mr. Blaine. I have never had the opportunity of examin¬ 
ing a rabid pig, and I much regret it.
