308 HERNIA, OR RUPTURE. 



When the horse can he spared, a strong dose of physic is an excellent vermi- 

 fuge, so far as the long round worm is concerned ; but a better medicine, and 

 not interfering with either the feeding or work of the horse, is emetic tartar, 

 with ginger, made into a ball with linseed meal and treacle, and given every 

 morning half an hour before the horse is fed. 



A smaller, darker-coloured worm, called the needle-worm, or ascaris, in- 

 habits the large intestines. Hundreds of them sometimes descend into the 

 rectum, and immense quantities have been found in the coecum. These are a 

 more serious nuisance than the former, for they cause a very troublesome irri- 

 tation about the fundament, which sometimes sadly annoys the horse. Their 

 existence can generally be discovered, by a small portion of mucus, which, 

 hardening, is found adhering to the anus. Physic will sometimes bring away 

 great numbers of these worms, but when there is much irritation about the 

 tail, and much of this mucus, indicating that they have descended into the 

 rectum, an injection of linseed oil, or of aloes dissolved in warm water, will be 

 a more effectual remedy. 



The tape-worm is seldom found in the horse. 



HERNIA, OR RUPTURE. 

 A portion of the intestine protrudes out of the cavity of the belly, either 

 through some natural or artificial opening. In some cases it may be returned, 

 but from the impossibility of applying a truss or bandage it soon escapes again. 

 At other times the opening is so narrow that the gut, gradually distended by 

 fasces, or thickened by inflammation, cannot be returned, and strangulated 

 hernia is then said to exist. The seat of hernia is either in the scrotum of the 

 perfect horse, or the groin of the gelding. The causes are violent struggling 

 when under operations, over-exertion, kicks, or accidents. The assistance of a 

 veterinary surgeon is here indispensable*.
