A PECULIAR AFFECTION IN THE HORSE. 
On the 4th of the following month we perceived that there was 
a superficial glandular swelling, of the size of a nut, on her right 
side, accompanied by a general state of lowness of spirits and 
exhaustion, which formed a remarkable contrast with her former 
vigorous habit. 
5th. — M. Damalix and myself examined her, and we were con- 
vinced that the symptoms that she exhibited proceeded from a 
state of serious disease, the nature and seat of which we could not 
determine. 
The following were her present symptoms : — General loss of 
spirit — the head carried low and resting upon the manger — the 
eyes almost closed, and weeping, the conjunctiva of a yellowish 
white, with the capillary vessels well marked — the pituitary mem- 
brane of a paler colour, and covered with small reddish points — 
the mouth hot and clammy, without any redness of the tongue — 
the food taken with indifference, and very slowly masticated — 
slight constipation — the pulse small and quick— a peculiar expres- 
sion of the countenance, with a slow and staggering gait. 
Diagnosis. — We were inclined to anticipate the development of 
acute mange, or gangrenous coryza. 
Treatment. — We abstracted four pounds of blood from the ju- 
gular. There was nothing amiss in the jet or character of the 
blood as it flowed. We administered a strong aloetic drink, in 
order to produce some general disturbance of the system. 
Physical Characters of the Blood. — The blood, as it coagulated, 
exhibited such peculiar characters and changes that we will record 
them, day by day, unto the close of the disease. 
Being received into the proper vessel, it coagulated in about 
nine minutes. The black clot was three times larger than the 
white. Twenty-four hours after it had been drawn from the vein, 
the quantity of serum was about half as great as we generally 
observe it to be. It very nearly equalled the size of the white clot. 
The red clot — le caillot cruorique — which offered a certain degree 
of resistance an hour after its coagulation, was insensibly changed 
into a black, broken-down mass, without any peculiar smell, four- 
and-twenty hours after it had been in the vase. The white clot 
had preserved its natural consistence : it was only somewhat 
whiter, and more elastic. The line of demarcation between the 
white clot and the cruorique one was well marked ; but on the 
surface of the cruor, and the superior part of it, and to the extent 
of a quarter of an inch, it presented a deep green-grass colour, 
which insensibly mingled with the brown tint of the clot. 
Independent of the diminution in quantity of the serous part of 
the blood, that, too, had acquired a greenish yellow tinge, and a 
viscidity like the synovial fluid. It separated itself more slowly
