A PECULIAR AFFECTION IN THE HORSE.

than in its natural state from the other constituent parts of the 
blood. After twelve hours only, it had gained upon the superior 
part of the white clot so much as to form a layer two lines in thick- 
ness in about twenty-four hours. At this period it was covered by a 
thin pellicle, easily to be taken off with a little precaution, slightly 
yellow on its superior surface, and covered inferiorly by a greasy 
matter of a green colour, which, in our opinion, might give to the 
serum the oleaginous appearance of which we have spoken. Be- 
side this, as if it had been endowed with some corrosive property, 
it had indented the superficies of the white clot with small aper- 
tures, irregular in their form and their depth. 
Q>th. The patient was in a state of depression, even more marked 
than on the preceding evening. The conjunctiva was of a deeper 
red, and the pituitary membrane presented the same colour, with 
petechial spots on its surface. 
Diagnosis . — We are still more inclined to believe, that acute 
mange is at hand. 
Treatment . — Again we bled to the extent of four pounds, and 
administered emollient injections ; friction was also frequently ap- 
plied. The purgative had not acted, although twenty-four hours 
had passed since the administration of it. The blood presented 
the same characters, except that the serum was somewhat less in 
quantity. Its colour was deeper, and its viscidity was greater. 
1th, Qih, 9 th and 1(M. The prostration of strength increases — 
the animal is almost insensible to the objects by which she is sur- 
rounded. She resembled a horse violently attacked by vertigo 
or epilepsy. The pulse and the beatings of the heart have not 
varied from the beginning. The quantity of serum has diminished, 
but the viscidity has increased. The solid parts of the blood offer 
no change. 
On the 11th of April, at half-past 11 o’clock at night, she died. 
During the course of that day we had observed a series of symptoms 
which betrayed great suffering. The countenance was anxious — 
the head was moved backwards and forwards, to the right and to 
the left ; the limbs were approached, as nearly as possible, to the 
centre of gravity, and the back bowed as if in violent colicky pains, 
and then the animal would suddenly lie down, moaning sadly. 
Having lain down, she stretched out every limb, strangely stiffen- 
ing them. There were frequent and convulsive yawnings — abundant 
and glutinous salivation — spasmodic closing of the jaws, alternating 
with violent grinding of the teeth — indisposition to feed — the 
mucous membranes becoming pallid — the pulse not to be felt — the 
beating of the heart 75. 
In describing the morbid lesions, we will follow the course of 
the disease, commencing with the organs that were most affected.
