The treatment should have strict relation to the real or supposed cause of jaundice, and its most evident concomitant circumstances. Some of these symptoms are constant and others variable. Among the first, whatever be the cause of the disease, we reckon acceleration of the pulse; fever, with paroxysms of occasional intensity; and a yellow or reddish-yellow discoloration of the urine. Among the second are constipation, diarrhoea, the absence or increase of colour in the faecal matter, whether solid or fluid. When they are solid, they are usually void of much colour; when, on the contrary, there is diarrhea, the fæces are generally mingled with blood more or less changed. Sometimes the dejections are nearly black, mixed with mucus. It is not unusual for a chest affection to be complicated with the lesions of the digestive organs, which are the cause of jaundice. With these leading symptoms there are often others connected that are common to many diseases; such as dryness and heat of the mouth, a fetid smell, a staggering gait, roughness of the hair, and particularly of that of the back; an insatiable thirst, accompanied by the refusal of all food; loss of flesh, which occasionally proceeds with astonishing rapidity; a tucked-up flank, with hardness and tenderness of the anterior part of the belly. The jaundice which is not accompanied with fever, nor indeed with any morbid change but the colour of the skin, will require very little treatment. It will usually disappear in a reasonable time, and M. Leblanc has not found that any kind of treatment would hasten that disappearance. When any new symptom becomes superadded to jaundice, it must be immediately combated. Fever, injection of the vessels of the conjunctiva, constipation, diarrhoea, or the discoloration of the urine, require one bleeding at least, with some mucilaginous drinks. Purgatives are always injurious at the commencement of the disease. "I consider," says M. Leblanc, "this fact to be of the utmost importance. Almost the whole of the dogs that have been brought to me seriously ill with jaundice, have been purged once or more; and either kitchen salt, or tobacco, or jalap, or syrup of buckthorn, or emetic tartar, or some unknown purgative powders, have been administered.
