may be caused by an involution of one part of the intestine 

 within another. When owing to this cause, the difficulty is 

 frequently removed, by jerking the animal by the hind legs 

 several times, when the pain disappears. But it is generally 

 occasioned by costiveness, which see above*. This may be 

 prevented by using green food, roots, &c., once a week, or 

 by allowing them to browse on the evergreens, pines, &c. 



POISON from laurel and other plants, is cured by pouring 

 a gill of melted lard down the throat, or boil for an hour the 

 twigs of the white ash, and give a i to 1 gill of the strong 

 liquor immediately; to be repeated if not successful. 



INFLAMMATION OF THE LUNGS is produced by improper 

 exposure to cold and wet. The remedy for slight af lee- 

 ions, is warm, dry shelter, and light food. When severe, 

 resort must be had to bleeding and purging freely, then 

 to light bran or linseed mashes. 



ROT sometimes causes the death of a million of sheep in 

 a single year in England, yet it is a disease almost unknown 

 in this country. Foreign authorities ascribe it entirely to 

 excessive humidity of climate, wet pastures, or too watery 

 food. The preventives are therefore obvious. After the use 

 of dry food and dry bedding, one of the best is the abundant 

 use of pure salt. In violent attacks, early bleeding, followed 

 by a dose of '2 oz. Epsom salts, to be repeated if necessary, 

 with a change of diet and location, is all that can be done. 



FOOT-ROT is frequently a prevalent disease among Ameri- 

 can sheep. It is sometimes spontaneous, but more often pro- 

 duced by contagion. In the former case, it is caused by soft, 

 rich, or moist pastures. A dry gravelly or rocky range, will 

 of course be an effectual preventive when owing to this 

 cause. Contagion is communicated, by the absorbents of 

 the foot coming in contact with the suppuration, which has 

 been left on the ground from the diseased part. Absolute 

 safety against this contagion is secured, only by a a total 

 avoidance of the walks of the infected animals, till repeated 

 rains, or what is better, frosts have disarmed the virus of its 

 malignity. Remedies are variously compounded, of. blue 

 vitriol, verdigris, tar, spirits of turpentine, alum, saltpetre, 

 salt, lime, copperas, white lead, antimony, alcohol, urine 

 vinegar, &c., all of which are effectual. The hoof should 

 first be pared and thoroughly scraped. Then apply a wash 

 made of three parts of blue vitriol, one of verdigris pulverised 

 finely, with scalding (not boiling) vinegar; stirring briskly 

 till it is of the consistence of thin cream, and put it upon the
