_Symptoms_: There is vomiting, but not to the same extent as is seen in cases of arsenic poisoning. The vomited matter, when taken into the dark, is generally luminous, and it gives off that well-known odour of phosphorus which resembles the smell of garlic; the same perfume may be detected in the breath. If the dog survives the acute stage, in the course of a few days the symptoms of jaundice may develop; there is also a tendency to hæmorrhage from the nose. Poisoning by phosphorus is often followed by convulsions, but sometimes coma; in other cases noisy delirium. _Treatment_: In treating cases of poisoning by phosphorus, oils and other greasy substances must be always avoided, as it easily dissolves in anything of an oily nature, and when such occurs greater mischief happens. An emetic of sulphurate of zinc, from five[1] to twenty grains in warm water, should be given as quickly as possible, and repeated in ten minutes. If it has not acted, salt and water or ipecacuanha wine may be given instead of the zinc, when the latter cannot be obtained. After the sickness has ceased, administer a free dose of Epsom salts, and keep the dog’s strength up with Brand’s beef-tea jelly; also give barley or rice water to drink. _Carbolic Acid_: _Symptoms_: The dog shows signs of great pain, and is violently sick; the lips, mouth, and tongue are white, swollen, and hard. There is great prostration and signs of collapse, the lips and ears being cold. The urine is of a dark brown colour, sometimes even black, or it may be altogether suppressed. When a fatal dose has been taken, the pupils are contracted, the dog soon becomes comatosed, breathing difficult, and death follows. It is rather characteristic of carbolic acid poisoning that the patient, a short time before death, often seems to rally, making one (even persons of experience) think that the worst has passed, and that he is going to get better. But a sudden collapse often occurs, and death takes place unexpectedly. All cases do not run this acute course; the membrane of the tongue and mouth may be badly burnt, which peels off, leaving a large raw surface, which ulcerates. The same may occur in the throat, and even in the stomach and bowels; and the dog gradually dies from exhaustion, or even blood poisoning, a week or ten days after the accident has happened.
