tapid and effectual in stimulating the vessels to a heaithy action, and 
on that score should be preferred. If the lampas is owing to the cutting 
of a grinder, relief will be afforded by a crucial incision across the pro- 
truding gum. 
Barss, paps, &c.—The swelling at the mouth of the ducts may gene- 
rally be relieved by a dose of physic and green food, but should it continue, 
a piece of lunar caustic may be held for a moment against the opening of 
the duct every second day, and after two or three applications the thicken- 
ing will certainly disappear. 
WHERE VIVES, or chronically enlarged submaxillary glands, are met 
with, the application of the ointment of biniodide of mercury, according 
to the directions given at page 456, will almost certainly cause their reduc- 
sion to a natural state. 
GASTRITIS. 
Gasrritts (acute inflammation of the stomach) is extremely rare in the 
horse as an idiopathic disease ; but it sometimes occurs from eating vege- 
table poisons as food, or from the wilful introduction of arsenic into this 
organ, or, lastly, from licking off corrosive external applications, which 
have been used for mange. The symptoms from poisoning will a good 
deal depend upon the article which has been taken, but in almost all cases 
in which vegetable poisons have been swallowed, there is a strange sort 
of drowsiness, so that the horse does not lie down and go to sleep, but 
props himself against a wall or tree with his head hanging almost to the 
ground, As the drowsiness increases he often falls down in his attempt 
to rest himself more completely, and when on the ground his breathing 
is loud and hard, and his sleep is so unnaturally sound that he can 
scarcely be roused from it. At length convulsions occur and death soon 
takes place. This is the ordinary course of poisoning with yew, which is 
sometimes picked up with the grass after the clippings have dried, for in 
its fresh state the taste is too bitter for the palate, and the horse rejects 
the mouthful of grass in which it is involved. May-weed and water 
parsley will also produce nearly similar symptoms. The treatment in each 
case should be by rousing the horse mechanically, and at the same time 
giving him six or eight drachms of aromatic spirit of ammonia, in a pint 
or two of good ale, with a little ginger in it. This may be repeated every 
two hours, and the horse should be perpetually walked about until the 
narcotic symptoms are completely gone off, when a sound sleep will restore 
him to his natural state. 
ARSENIC, when given in large doses, with an intention to destroy life, 
produces intense pain and thirst ;—the former, evidenced by an eager gaze 
at the flanks, pawing of the ground, or rolling; and sometimes by each 
of these in succession. The saliva is secreted in increased quantities, and 
flows from the mouth, as the throat is generally too sore to allow of its 
being swallowed. The breath soon becomes hot and fetid, and purging 
them comes on of a bloody mucus, which soon carries off the patient by 
exhaustion, if death does not take place from the immediate effects of the 
poison on the stomach and brain. Z'reatment is seldom of any avail, the 
most likely remedies being large bleedings, blisters to the sides of the 
chest, and plenty of thin gruel to sheathe the inflamed surface of the 
mucous membrane, which is deprived of its epitheliai scales. 
CORROSIVE SUBLIMATE is sometimes employed as a wash in mange, or to 
destroy lice, when it may be licked off, and will occasion nearly the same 
symptoms as arsenic. The treatment consists in a similar use of thin starch
