assisted by lots of patience on the part of the owner. No injec¬ 
tions should be employed, and the less the wound is interfered 
with the better, either with bistoury or probe. In 99 cases in a

set herself right. 
How long may a crih-biter live 1 Generally speaking, till his 
legs are worn out, and he is destroyed in consequence; or till he 
becomes so poor as to be unpleasant to the eye, and for this offence 
receives his death-warrant. Instances of old horses, who are also 
old crib-biters, are numerous. 
Has grogginess of two months' standing ever been perfectly 
cured? This term grogginess is not sufficiently definite—obscure 
foot lameness of two months’ standing has certainly been cured; 
but if ulceration has commenced in the navicular joint, we may 
relieve—we may palliate—we may patch up; but a cure—a per¬ 
manent cure—is seldom if ever effected. 
How soon may specific ophthalmia produce visible cataract? 
Generally speaking, cataract is not perceptible till after repeated

Are Epsom salts a good and proper purgative for sheep 1 An 
agricultural friend tells me, that, whenever he has given them, their 
exhibition has been invariably succeeded by death in a short time 
afterwards. 
A CASE OF THE SUCCESSFUL USE OF THE 
DINIODIDE OF COPPER. 
By Mr. W. Baddeley, V.S., Staffordshire Potteries. 
On the 9th of November last, Mr. Kelshall, of this town, called 
on me to look at a brown mare, aged, and rather low in condition, 
with what he called a humour in the off hind leg. He had given 
her a few diuretic balls, with exercise, but she got no better. On 
examining the leg, I found a small wound on the point of the hock, 
but not deep. The limb was much swollen, hot, and painful. T 
gave a bottle of lotion to apply to the hock, and ordered her to be 
prepared for a dose of physic, with bran mashes, &c.
