ON CIIOLKIIA IN DOMESTICATED ANIMALS.

The attack was sudden—in a moment. The first appearance 
was a cramp in the hind legs : she seemed to suffer acute pain, 
particularly in one leg; her eye of a wild, staring, and terrified 
appearance, as if sensible of the pain she had to suffer; her ex¬ 
tremities stiff and cold ; a singular quivering on the shoulder and 
thigh—a finger or thumb would have covered each part. I 
was particular in following your directions as to the treatment, 
which in the end had a decided effect. By first taking a large 
quantity of blood—a severe trembling took place—the same 
quantity of oil given as the others, and several bottles of hot 
water—two or three clysters given—frictioned wdth dry hard 
straw, till a proper heat was produced, and rolled in woollen cloths. 
I have not used fomentation, as in cases when the disease had 
got a greater length : she seems somewhat better at present; but 
would wish you to come this length to-night, if in your power.” 
He has, however, omitted some particulars, inasmuch as he 
does not mention that they were all affected, more or less, with 
purging; and in some of them coagulated lymph formed a great 
portion of what w'as discharged. In some, the purging appeared 
first; in others, the cramps of the legs. It is here proper to 
observe, that a chano-e of feeding had been introduced into the 
byre about eight or ten days before the disease broke out. In 
consequence of the scarcity of Swedish turnips, potatoes had 
been substituted, and to this cause the disease might have been 
attributed; but in other cases this cause was not so apparent. 
The cows that were attacked w^ere standing in various parts of 
the byre. 
In a cow belonging to a gentleman, which I saw just as she 
w'as dying, there w'as a great degree of blueness about the muz¬ 
zle, which was strongly contrasted with the natural whiteness of 
the part. 
I may further remark, although it does not bear directly upon 
the subject before us, that wdthin the last few months I had ob¬ 
served some cases of erythematous disease, which is rather a rare 
affection in the horse :—First, a mare, belonging to Mr. Cunning¬ 
ham, of Culross, was suddenly affected with an eruption over the 
whole body, strongly resembling nettle-rash in the human being, 
attended with dulness, loss of appetite, slight soreness of the throat, 
mouth moist, pulse soft, and little increased; being only 50; 
these sw'ellings on the surface of the body almost entirely disap¬ 
pearing in about twenty-four hours. She was observed by the 
hostler to be cold and uneasy about noon for two days after¬ 
wards ; and on the third day, in consequence of my having 
desired him carefully to watch her, a slight shivering was observed 
from twelve at noon till about one p.m. Considerable weakness
