liable to produce introsusception, or entanglement, of them ; 

 and the case is then hopeless. 



SuPEEPURGATioN often follows the administration of a too 

 strong or improper dose of physic. The torture which it pro- 

 duces will be evident by the agonized expression of the coun- 

 tenance, and the frequent looking at the flanks. Plenty of thin 

 starch or arrowroot should be given both by the mouth and by 

 injection; and, twelve hours having passed without relief being 

 experienced, chalk, catechu, and opium should be added to the 

 gruel. 



Worms in the intestines are not often productive of much 

 mischief, except they exist in very great quantities. Small 

 doses of emetic tartar or calomel, with a little ginger, may be 

 given to the hoi se half an hour before his first meal, in order to 

 expel the round white worm ; it must be worked off with lin- 

 seed oil, or aloes, and injections of linseed oil or aloes will usually 

 remove the ascarides, or needle-worms. 



Catarrh, or cold, inflammation of the upper air-passages, 

 should never be long neglected. A few mashes, or a little 

 medicine will usually remove it. If it is neglected, and, occa- 

 sionally, in defiance of all treatment, it will degenerate into 

 other diseases. The larynx may become the principal seat of 

 inflammation. 



Laryxgitis will be shown by extreme difiiculty of breath- 

 ing, accompanied by a strange roaring noise, and an evident 

 enlargement and great tenderness of the larynx when felt ex- 

 ternally. The windpipe must be opened in such case, and 

 the best advice will be necessary. Sometimes the subdivi- 

 sions of the trachea, before or when it first enters the lungs, will 

 be the part affected, and we have bronchitis. Tliis is character- 

 ized by a quick and hard breathing, and a peculiar wheezing 

 sound, with the coughing up of mucus. Here, too, decisive 

 measures must be adopted, and a skilful practitioner employed. 

 His assistance is equally necessary in distemper, influenza, and 

 epidemic catarrh, names indicating varieties of the same dis- 

 ease, and the product of atmospheric influence ; diffeinng to a 

 certain degree in every season, but in all characterized by 

 intense inflammation of the mucous surfaces, and rapid and 

 utter prostration of strength, and in all demanding the abate-
