ANIMAL PATHOLOGY. 
Flying Lameness . — What do we do? We abstract a little 
blood — we give a dose of physic — we foment the whole of the 
limb — we put some additional clothing on the animal ; and the 
next morning we often find him well, or we find that leg well 
and another leg similarly affected. Is this neuralgia or rheuma- 
tism? or a compound of both ? These are questions which we 
cannot answer; for our patient cannot point out to us the precise 
situation of the pain, as being in the course of a nerve, or spread 
over the fibrous membrane of a joint. 
French Opinions of it . — In the French school neuralgia is de- 
cidedly admitted as a malady to which the horse is occasionally 
subject; but it is said to be accompanied by that peculiar twitch- 
ing whence it derives one of its names — the tic doloureux, or 
painful muscular spasm : at least it is affirmed, that this is the 
only symptom by which it can be recognized. 
Hurtrel d’Arboval, professing to quote from the records of the 
veterinary school at Lyons, speaks of a horse that had a con- 
vulsive agitation of the head up and down, and other unusual 
but momentary muscular spasms, and evidently suffering a great 
deal of pain, but in every other respect being apparently well. 
A long course of anti-spasmodic treatment had no effect upon 
him ; but he was cured by being put to severe post work. This 
account is very unsatisfactory, and the case appears to be one of 
chorea instead of neuralgia. I have in vain searched the records 
of this school for the original description of the case. 
Vatel gives the most unobjectionable account of it. He says 
that “the absence of heat of the skin, and frequency of the 
pulse, contrasted with the evident intensity of the pain and the 
disordered function of the part, form the surest diagnosis. In- 
flammation sometimes succeeds, especially when the attack is of 
long duration ; then the lesions observed on dissection are of an 
inflammatory character.” 
Pruritus . — That the domestic animals are subject to intense 
and intolerable pruritus, we have almost daily proof. The suffer- 
ings of a dog with acute red mange, and the lacerations which 
he sometimes inflicts upon himself, are dreadful. I have seen 
him wrought up to that pitch of insanity, that he has torn 
great pieces of integument, and even of muscular substance, out 
of his flanks and the inside of his thighs. It was scarcely 
a week ago that a mare in our infirmary with a papular eruption 
on her haunches, broke her halter in the night, and blemished 
herself for life by tearing away mouthfuls of hair and of inte- 
gument too. A lotion of diluted hydrocyanic acid afforded her 
almost immediate relief. Sheep affected with the scab appear
