450 REPORT OF THE COMMISSIONER OF AGRICULTURE. 
veterinary surgeon-general, who, at my solicitation, came immediately 
and examined the animal. He did not pronounce it a clear case of glan- 
ders, but doubted, at least hesitated. The owner, however, consented 
voluntarily to have the horse killed. The post mortem examination re- 
vealed pulmonal glanders in a very advanced stage. A similar ease, of 
which I shall have to give a brief account in another chapter, I had an 
opportunity to observe in 1866, near Dixon, Lee county, Liliois. 
As the principal symptoms of pulmonal glanders are essentially, for 
some length of time at least, only such as are also observed in common 
cases of heaves (one of the most frequent disorders of horses), the diag- 
nosis must frequently be based, as a lawyer would say, upon cireumstan- 
tial evidence. " 
A horse must be suspected of being affected with glanders, first, if the 
peculiar, weak, and dry cough constitutes, compared with the diffieulty 
of breathing, the predominating symptom; if the animal becomes more 
and more emaciated and hide-bound, and if the appearance of the coat 
of hair is such as to indicate the presence of a cachectic disease. See- 
ond, if it is known that the animal in question has been exposed to the 
- contagion. Third, if other horses have become affected with glanders 
or farey, after having been together with the animal that shows those 
symptoms. Fourth, if a horse apparently affected with heaves has pre- 
viously exhibited other symptoms, more or less characteristic or suspi- 
cious, of glanders. Fifth, if other symptoms, such as are observed in 
so-called ‘‘ nasal gleet,” or incipient nasal glanders, make their appear 
ance. 
de FARCY, OR EXTERNAL GLANDERS. 
The name “farey” is given to such cases of glanders in which the 
morbid process has its seat in, and immediately beneath, the skin, and in 
which nodules, boils (glanders-buboes), and ulcers of a very inieectious 
and chanerous character make their appearance in the subcutaneous 
tissue, and in the skin itself. Glanders-nodules and lenticular ulcers in , 
the tissue of the skin, boils beneath the skin, smaller and larger open 
ulcers penetrating the same, a strand-shaped swelling of the subeuta- 
neous lymphatics, swelled lymphatic glands, and wdemata, the latter 
especially in the legs and on the head, constitute the most essential 
symptoms. 
Professor Gerlach discriminates two forms: Subcutaneous glanders 
or common farcy, and exanthematous glanders or skin farcy. 
(a.) Subcutaneous glanders or common farcy.—The morbid process in 
this rather frequent disease has its principal seat in the subcutaneous 
connective tissue, and in the lymphatic system of the skin and be- 
tween the skin and the muscles, but especially on the inner side of the 
hind legs, on the lips, on the neck, between the fore legs, and on all such 
places where the skin is thin and fine. At first distinctly limited swell- 
ings of an inflammatory character (incipient boils or glanders-buboes) 
make their appearance in the subcutaneous tissue. These swellings or 
boils soon commence to dissolve, or to decay, from within; the ulcera- 
tion begins in the center, but the matter, being very corrosive, soon 
works its way into the skin, the boil finally opens, and presents a 
farcy-uleer with a steatomatous bottom, and elevated, corroded, and in- 
flamed borders. At the same time, or even before the formation of the 
first ulcer has become completed, deleterious matter is absorbed by the 
nearest lymphaties, and deposited in the lymphatic glands. ‘The for- 
mer, in consequence, swell to hard and plainly visible cords or strands, and 
the latter to painful and distinctly limited tumors. The partial or total
