This affection is, like all others of the same kind, either acute or chronic. The former very rarely occurs except from poison, or highly improper food, which has the same effect. The symptoms are a constant and evidently painful straining to vomit, with an intense thirst, dry hot nose, quick breathing, and an attitude which is peculiar - the animal lying extended on the floor, with his belly in contact with the ground, and in the intervals of retching licking anything cold within reach. The treatment consists in bleeding, if the attack is very violent, and calomel and opium pills, of a grain each. These pills are to be given every four hours, to be followed with two drops of the diluted hydrocyanic acid, distilled in a small quantity of water. Thin gruel or arrow-root may be given occasionally in very small quantities, but until the vomiting ceases, they are of little service. If poison has clearly been swallowed, the appropriate treatment must be adopted.
Chronic gastritis is only another name for one of the forms of dyspepsia, the symptoms and treatment of which are given elsewhere.
