    [66] Worms. There are three kinds of worms found in horses. The most common and mischievous reside in the stomach, and are named bots. They are of a reddish color, and seldom exceed three quarters of an inch in length. At one extremity ^hey have two small hooks, by which they attach themselves, and the belly seems to be covered with very small feet: They are most frequently found adhering to the insensible coat oft'ie stomach, and then they do not appear to cause any considera- ble uneasiness or inconvenience. Sometimes, however, they attach themselves to the sensible part, and do great injury to this important organ, keeping up a constant irritation, and there- by occasioning emaciation, a rough staring coat, hidebound, and a cough. I have met with several instances of their des- troying the horse, by ulcerating the stomach in a considerable degree; and cases are recorded where they have penetrated quite through the stomach. It is astonishing with what force these worms adhere, and how tenacious they are of life: they have been found to resist the strongest poisons, nor have we yet discovered any medicine capable of destroying them, or of detaching them from their situation. It seems probable that this worn), like the catterpillar, undergoes several changes. It is said to Le originally a fly, which, depositing its eggs in the horse's coat, causes an itching that induces him to bite the part. In this way he is supposed to swallow some of the eggs, which, by the heat of the stomach, are brought to maturity, and pro- duce bots. When the bots are fit to assume the chrysalis slate, they are spontaneously detached, and gradually pass oli' with the faeces. This is the most rational account we have of their production. It has been asserted, that the fly from which bots are pro- duced crawls into the anus of horses, and deposits its eggs there; that the worms when hatched soon find their way further up the intestines, and often penetrate into the stomach. This account is literally copied by a late writer on Veterinary Pathol- ogy;* but it. appears to me rather strange, that any one who has considered die structure of the horse's intestines should fi,r a moment give credit to it. It seems impossible indeed for these worms to crawl from the anus to the stomach; and, as far as irry observation-'goes, tliey^ are never found residing in the intestines. Sometimes we find two or three, but they are evi- dently proceeding towards the anus to he expelled, I have be- fore observed, tiiat I am not acquainted with any medicine that •Ryding's Veterinary Pathology.
