260 INTESTINAL PAEASITES. 



young pigs. Ascarides and tseniae are occasionally asso- 

 ciated with the echinorhynchus, producing emaciation, weak- 

 ness of the loins, and rigidity of the hind extremities. In 

 the morning, and until feeding time, the pigs grunt and cry 

 out incessantly, and have even a tendency to bite each other. 

 The fseces become hard and dry, the skin tense, eyes sunken, 

 and the visible mucous membranes are pallid. Debility in- 

 creases, and the animals die from exhaustion. 



Treatment consists, in the early stage, in the administration 

 of a couple of croton beans in food. If by purgation the para- 

 sites are not removed, sulphur may be given' freely. In a 

 strong pig a quarter of an ounce of turpentine may be given in 

 four ounces of linseed oil and a little gruel. Great care must 

 be exercised not to kill the pig in administering draughts.* 



Dogs are often troubled with worms, and most frequently 

 with taenia cucumerina, tsenia serrata, and with the round 

 worm, ascaris marginata the maw- worm; the latter very 

 frequently requires to be expelled. 



Some dogs with tapeworm are not much disturbed, and 

 their condition is only suspected from the appearance of 

 rings of the worm on the tail or excrement. There is, how- 

 ever, constipation, straining, and uneasiness in many in- 

 stances. . It is at all times desirable, especially on farms, to 

 keep dogs clear of tapeworms. 



The maw-worm is displaced readily, especially in young 

 dogs, by means of the following electuary : 



Iron filings . . . . 1 oz. 



Treacle . . . . 4 



A teaspoonful morning and night to dogs. 



Young dogs improve largely on the above treatment. A 

 decoction of quassia or lime water may be used as an injec- 

 tion, with the effect of displacing the parasites. A brisk
