ON EPIZOOTIC DISEASES. 
discharged from the skin of a green colour. There is a sad de- 
gree of itching. The animal is continually rubbing himself against 
the trees and walls It is exceedingly contagious. 
The fourth species is an articular disease — morbus articularis. 
It principally attacks the feet. The skin clings to the bones — it 
is rough and hard to the touch — the bone of the spine is pushing 
through the skin — the hair stands on end — the whole body 
seems contracted and curved and extenuated by famine. This 
disease rapidly progresses, day after day, and it is with great diffi- 
culty that its progress can be arrested. 
The fifth species is farcy — morbus far cinosus. In this disease, 
on many parts of the body, and particularly on the hind limbs, 
numerous granules or small tubercles are collected together. 
They appear on the haunch — on the parts of generation — on the 
sides — on the articulations. The tubercles disappear on some 
parts to shew themselves more thickly and annoyingly on others. 
The animal evidently grows thin, although his appetite continues 
the same. Sometimes all the eruptions disappear for awhile, 
and he seems like other animals. Bleeding is of no service in 
this disease. 
The sixth species is connected with the kidneys — morbus sub- 
renalis. It appears to resemble more a disease of the kidneys 
than any thing else, and therefore the name that is given to it. 
Sometimes the whole of the hind limbs are seemingly affected 
with palsy. The animal is unable to move. This is generally 
a fatal symptom. He coughs with pain — his countenance ex- 
presses dreadful suffering — the skin adheres to the parts be- 
neath — the spine of the back is prominent — the patient loses all 
inclination to eat or to drink — he almost seems to get thin as we 
look upon him — and, if prompt succour is not afforded, he dies. 
The loins are the parts first affected. 
The seventh species is the morbus elephantiasis — the leprosy of 
quadrupeds. The skin is rough and hard to the touch — there is 
a burning heat over the whole of the body, especially on the 
back — large scabs are formed, resembling the bark of trees — the 
nose, the head, and the feet, are covered with small granules or 
pustules. Ozena frequently accompanies this disease. 
Beside these seven species of disease, of which the greater 
part are chronic, there are others of an acute character ; of this 
kind are those allied to mania, whose seat is principally in the 
head. The patients neither see nor hear as usual. They are 
either dull and stupid, or become formidable by their disposition 
to mischief. They die before they scarcely begin to lose flesh. 
Such is the account which Vegetius has left of the diseases 
most to be feared, and the greater part of which have occasionally,
