FARCY IN EGYPT. 
JVIinor, and Arabia. It was known to the ancients, but we pos¬ 
sess few documents of its march or its development, and we are 
ignorant of the place whence it had its origin. It is an affection 
peculiar to the horse, the ass, and the mule, but some have 
thought that they had observed it in the It consists of the 
existence of tumours on the skin of greater or less size, and which 
take on them the form of chaplets, knotted cords, buds, or but¬ 
tons, round, oval, ffat, globular, adhering to the skin, or being 
immediately beneath the skin, more or less hard, and finishing 
by softening and suppurating. At the commencement of the 
eruption pressure on the tumours causes considerable pain; the 
lymphatic vessels are much developed, and can be plainly felt; 
there is infiltration and tumefaction of the limbs, with pain and 
great swelling of the testicles, and of the sheath of the penis, and 
of the exterior lymphatic ganglions ; and also anasarca. 
These little tumours or buds appear on every part of the body ; 
on the abdomen, the scrotum, the anus, the tail, the back, the 
loins, the shoulders, the neck, the head, the eyelids, the con¬ 
junctiva, the membrane of the nose, the nasal septum, the coro¬ 
net, and principally on the extremities, where they follow the 
course of the lymphatic vessels. They often appear first of all 
on the extremities, or on the head or neck. 
A single button is perhaps first perceived, which is speedily 
followed by many others. The skin becomes thin, it ulcerates, 
and discharges a matter sometimes thick and white, and some¬ 
times grey or bloody, and sometimes viscid and yellow : now it 
will fall in drops, and presently it will harden upon the skin. 
The ulceration increases—the discharge is fetid ; it has a smell 
sui generis. Fungous excrescences, elevated, rounded, bleeding, 
appear; to these succeed large ulcers, covered by a yellow thick 
crust, thin towards its edges. On the limbs of many horses 
we have seen tumours of a scirrhous ’ nature, and they have 
become of a considerable size. 
In the nasal cavities the buds are generally small—occa¬ 
sionally large; they are, at first, hard—they soften ; they extend 
considerably; they render the septum of the nose, and the 
bones of the nose, carious; and there is an abundant and fetid 
discharge, variable in colour. 
These buds are confined to the exterior membranes. Under 
the skin, and in the interstices of the muscles, voluminous and 
hard tumours are frequently formed. 
All four limbs often enlarge at once. After a certain time, 
the heat and tenderness observed at the commencement of the 
disease disappear. The softening of the buttons causes the 
horn to be detached at the coronet, and pus is thrown out
