_Symptoms_: Vomiting of blood, sometimes of a bright red colour, at other times dark red or venous blood; and when it has been retained in the stomach some time, it comes up liquid of a coffee colour. _Treatment_: Give the following mixture:— _Recipe_: Tincture Thalaspi, 24 drops. Liquor Bismuth, ½ ounce. Water to 3 ounces. _Doses_: One teaspoonful to a tablespoonful[1] every three or four hours. _Diet_: Milk, also Benger’s food with milk, kreochyle with Vichy water. Brand’s essence and milk, either peptonised or plain, is the best food. When sickness is very severe, stomach should be rested for twenty-four hours, and the dog fed with nutritive enema, say from one[1] to six tablespoonfuls peptonised milk every three hours alternately, with a beef suppository (B and W). These may be purchased in different sizes. =Blindness, Amaurosis=: _Symptoms_: Eyes clear and bright, pupils large, with a greenish look. Loss of colour to eye—as the iris is so dilated, cannot be seen or scarcely seen. Sometimes follows distemper; a result of fits; great excitement or exertion, as violent vomiting. Pupil will not contract when exposed to light, except very strong sunlight. _Treatment_: Disease seldom curable. Try following eye drops:— _Recipe_: Sulphate Eserine, ½ grain. Water to 1 ounce. One drop to be placed in the eye three or four times a day. Give one[1] to seven drops tincture nux vomica three times a day in water after food. Blisters or seton to back of neck can be tried; also galvanism. =Blisters=: Collection of blood, water, or serum under first skin; result of a burn as a rule. _Treatment_: Cut blister, squeeze out contents, apply boracic ointment on lint, and bandage. =Blisters, To Apply=: It is somewhat difficult to raise a good blister on a dog—much more so than on a horse, or even a person; but a fluid called liquor epipasticus will do so if properly applied. The hair should at first be cut off closely from the part where it is intended to apply the blister; the skin should be then thoroughly washed with warm water and soap, and afterwards well dried. Then the blister should be rubbed on with a piece of wool tied around a stick for about five minutes. The person applying the blister should be careful not to get any of it on his fingers, as it may make them very sore. Over the blister put a piece of either grease-proof paper or brown paper, and apply a bandage. This blister is very poisonous, and the dog must not be allowed to lick it on any account. The next day, if the skin is not well blistered, rub in for two or three minutes a little red blister ointment. Forty-eight hours after the first application of the blister it may be washed off, the parts carefully dried with a soft cloth, and then anointed with boracic ointment. =Blood Poisoning=:
