INTESTINAL PAKASITES. 259 



dered sulphate of iron, given in treacle as an electuary. The 

 worms are rapidly discharged, and the young animal acquires 

 strength and condition. Cows are not often troubled with 

 tapeworm, though two kinds tsenia expansa, and tsenia 

 denticulata are occasionally met with in their intestines. The 

 only symptoms of their presence during life are the discharge 

 of rings of the worms, attended by a little intestinal irrita- 

 tion. The best remedy is turpentine in mucilage, or thick 

 linseed tea." 



In the sheep, various species of strongylus, such as Str. 

 cernuus and contortus, inhabit the intestine, but only one 

 tapeworm is known (tcenia expansa.) Though little is 

 known of tapeworm in the sheep in this country, neverthe- 

 less in some parts of the world this parasite is very trouble- 

 some, and destroys many lambs. If I am correctly informed, 

 this is the case in Australia, where, after torrents of rain, 

 portions of tapeworms are readily seen in large numbers on 

 the washed soil. Thus existing as an enzootic affection, it is 

 of great importance, as sheep affected with tapeworm pine 

 and become emaciated, as well as predisposed to a number of 

 other diseases which prove destructive. No properly de- 

 vised means of cure has been suggested. Overstocked land 

 appears to suffer most, and it may be necessary to reduce 

 the number of sheep kept. All the advice that can be given 

 is based on the well-known fact, that in proportion as you 

 invigorate the systems of animals, they are less subject to 

 parasitic disorders, so that sanitary precautions of a general 

 nature are to be adopted. In individual cases, the best 

 remedy is turpentine, given in drachm doses, in thick linseed 

 tea, linseed oil, or gruel. 



The pig is attacked by a large, round intestinal worm 

 (echinorhynchus gig as) a parasite which propagates rapidly, 

 and produces serious disturbance of the intestinal organs of
