. Diseases & disorders of the horse : a treatise on equine medicine and surgery. Horses; Horses -- Diseases; Horse Diseases. 8o notwithstanding the waste, the interior of the horse's stomach may become completely covered with the larvae commonly termed " ; When the bots, which hold on to the lining of the stomach by means of two large hooks, are perfectly grown, they release themselves, and are carried through the intestines along with the excreta, and thus they finally fall to the ground. They then bury themselves below the surface, in order to undergo a transformation from the condition of the bot, to that of the pupa or chr>^salis. When they ha^•e remained thus buried for six weeks, they make their way out of their enclosing cocoons, and emerge as perfect gad-flies. The male insects die, but the females live long enough to deposit their eggs, which are generally about forty in number. The bot passes about eight months of its existence in the stomach, where it is present in the winter months. It leaves in spring or early summer. The fly is developed from June to September, and after the latest females have appeared, all perish in October. Not uncommonly, the presence of bots in the stomach of the horse gives rise to considerable mischief. When very numerous, they may set up serious disease, sometimes even perforating the walls of the intestines. It is not always possible to diagnose the presence of bots in the stomach, but not unfrequently they may be seen in the excrement, or adhering around the anus. When there is reason to suspect their presence in very large numbers, it is well to place a piece of rock salt in the horse's manger, and to administer a drench, consisting of spirit of ether two ounces, of glycerine of carbolic acid three drachms, and of linseed oil a pint. This- may be repeated once every day for four The accompanying pictures show the various forms assumed by the oestrus equi. A is the larva or bot, B is the pupa ca
