farcied, whatever attention may have been paid to his food and 
treatment. 
M. Renault has seen, in the course of the last year, a new 
species of farcy which has not been described by any author. 
It is characterized by the development, almost instantaneously, 
and over a greater or less portion of the skin, of buttons, crowded 
one upon another ; but so small at first that, when they are found 
on a part of the skin covered with hair, their existence would 
not be suspected from the slight irregularity or elevation of the 
coat. These buttons rapidly increase in size ; and on the day of 
their formation, or the day afterwards, a small scab covers their 
summit. Under this scab, which soon falls off, an ulceration 
is established, not deep but spreading, which causes the epider- 
mis and the hair to be detached, and unites all the little wounds 
into one large ulcer, the appearance of which is hideous, and 
the smell fetid and repulsive. 
This ulcer, once formed, has a constant tendency to enlarge 
itself, yet still without much deepening ; the skin, the borders 
of which are at first hard, slowly ulcerating in its turn. That 
which contributes to prolong or to aggravate the evil, and to 
keep the wound almost continually bleeding, is the apparently 
tormenting itching of the part, and which excites the animal to 
be continually biting it, or rubbing it against every thing within 
his reach. The development of this disease is neither preceded 
nor accompanied by any febrile action, and the animal preserves 
his appetite, his condition, and his usual power. If the case 
finishes, as it too often does, by his being sacrificed, it is because 
of the repulsive appearance of the ulcers, whence exudes a sani- 
ous fluid, the stench of which infects the stable in which the 
horse is placed. 
The scrotum, the inside of the thighs, the anterior part of the 
arm, the croup, the shoulder, and the cheeks, are the parts on 
which this disease oftenest appears. Three horses, on which 
were ulcers of this kind, of long continuance, large and nu- 
merous, having been destroyed, we found, after careful examina- 
tion of tliem, no lesion but the diseased surfaces of the skin. 
The glands, the subcutaneous lymphatics nearest to the wounds, 
and even the lungs, were perfectly sound. The extirpation, or 
the general cauterization of the ulcerated surfaces — the applica- 
tion of caustic or absorbent powders — the greatest attention to 
cleanliness — diuretics and purgatives, were in their turn fruitlessly 
employed on the first horses that were submitted to treatment. 
With an exceedingly fine-pointed iron M. R. attempted to fire, 
separately, each of the little ulcers of which the large one was 
made up ; and, in some wounds, presenting a surface of more
