claws, with a considerable enlargement in the front of the foot, about 
the size of an egg, and which is very hard. It seems to be a bony 
deposit. The cow is as lame as ever. 
I am very sanguine with regard to the operation, although I am 
in the same situation with far too many of us—and a most shameful 
one it is—of never having seen it performed. I have, nevertheless, 
your valuable works on Cattle and Sheep. I have the owner’s 
consent, and, if you deem it advisable, the attempt shall be made. 
[I, of course, most strenuously advised the operation, the descrip¬ 
tion of which, and of its results, now sufficiently ascertained, 
would be most valuable.—Y.] 
ON CROUP IN YOUNG CATTLE. 
[I am not aware of any English veterinarian who takes notice of 
this affection in cattle. Descriptions are given of inflammation 
of the larynx and trachea and bronchial tubes; but not of that 
inflammatory state of some or all of them which occasions or 
terminates in the discharge of a viscid mucous exudation, or 
the production of a false membrane, of variable size and density. 
We are indebted to M. Barrere, V.S. at Lavardac, for two 
interesting cases of this disease. Some of our readers may, 
probably, be able to increase the list.—Y.] 
Inflammation of the mucous membrane which lines the respi¬ 
ratory passages sometimes presents very singular characters; 
and it is on account of this peculiarity that the inflammation has 
received a denomination little expressive of its character, but 
which usage has nevertheless sanctioned. 
This malady, which has been supposed to be very rare among 
animals, without doubt because it had been little observed, and 
perhaps also because it was confounded with some other affection 
of the respiratory canal, is more frequent than is generally ima¬ 
gined. I beg to relate two palpable cases of it. 
Case I.—On the 27th of March, in the present year, a heifer, 
fifteen months old, in good condition, of an irritable temperament, 
with frequent and painful cough,* was uselessly treated by the 
owner with inefficient gruel and white drinks. 
29M, 9 A.M.—Some alarming symptoms began to shew them¬ 
selves. The animal had lost all its spirit—the cough was painful 
and frc(|ucnt—the respiration difficult—the nostrils dilated—the 
tongue half protruded from the mouth, covered with a white foam.
