CONNEXION WITH GLANDERS AND FARCY. 785 
white spots deprived of hair are left behind, so that the horse 
looks speckled. 
Accompanying these symptoms there is great depression of the 
nervous energy. The senses become blunted ; the expression of' 
the animal is dull and heavy; motion of any kind is effected with 
difficulty; and there is great loss of power in the hinder extremi- 
ties. The author considers that this state o-f debility depends 
purely on an impression made on the nervous system. 
After the ulceration has continued for some time, knots or 
tubercles of various dimensions are developed beneath the skin. 
Some of these are as large as a dollar. They are smooth, firm, 
and elastic ; circular in form, and sharp-edged. There is neither 
pain on pressure, nor any remarkable redness of the parts or heat. 
They first make their appearance on the haunches, then on the 
head and throat ; afterwards upon the shoulders, breast, and 
other parts of the body, but have never yet been observed on the 
extremities. 
When they open on the surface, which very rarely occurs, a 
sero-lymphatic matter exudes. After a time this discharge dries 
up, and the tubercles disappear. 
In proportion to the duration and number of the tubercles be- 
neath the skin, and the ulcers on the surface, is the liability of 
the large glands to take part in the disease. Swelling of these 
glands takes place, and in verv many instances a chronic glandu- 
lar affection is the consequence, which not unfrequently termi- 
nates in glanders ; and when the formation of the tubercles has 
prevailed throughout the course of the disease, and the morbid 
secretion has been checked, it ends in farcy, rapidly followed by 
a fatal result. 
Glanders and farcy are not invariably the diseases in which 
this affection terminates. Sometimes a general relaxation of the 
system ensues. Shiverings, never of the whole body, but occu- 
pying individual layers of muscles only, and in single muscles 
resembling the catchings of galvanism, may be observed. These 
partial rigors are accompanied by extreme weakness of the pos- 
terior limbs. 
In some singular instances the loss of power affects one ear or 
the lower part of it; in others, the extreme portion only of these 
organs is affected, so that the tip of the ear, for instance, is bent 
at an acute angle, as if the cartilage was broken. 
Finally, the paralytic affection varies as much in the form 
which it assumes as in the degree, the situation, and the symp- 
toms accompanying it. 
In a few weeks the animal sinks under these symptoms; the 
ulcers and tubercles, in some instances, terminating before death
