84 THE INTERNAL PARASITES OF 



action, accompanied with nausea and spasmodic colic, 

 irritation, a voracious appetite, and more or less loss of 

 flesh. In addition, there may be foetor of the breath, 

 accompanied by a short, husky cough and an im- 

 poverished state of the coat ; and, either with or without 

 any of these symptoms, there may be more or less 

 paralysis. I may here make mention of an interesting 

 case of paralysis in puppies brought under my notice by 

 Mr. Lewis {The Field, Dec. 7, 1872), in which it was 

 instructive to notice how complete a cure followed the 

 administration of a simple aperient drug. Quite recently 

 also, a correspondent, writing from Ceylon under the 

 signature of " Veddah," gave a suggestive instance where 

 paralysis in dogs seemed to be entirely due to worms {The 

 Field, March 15, p. 238). 



A great variety of anthelmintics have been recom- 

 mended ; but for this particular worm there is probably 

 nothing better than castor oil and santonine. As with 

 the lumbricoids of man, so with those of the cat and dog ; 

 in either case they seem powerless to resist the action of 

 this remedy. In the human subject I have known a 

 grain of santonine sufficient to expel a lumbricoid as 

 large as a lob worm ; and in the dog or cat similar expe- 

 riences have followed the employment of from three to 

 five grain doses. Several of my pupils have adopted this 

 mode of treatment with success. The employment of 

 more powerful vermifuges is rarely necessary ; and even 

 the areca-nut powder should generally be reserved for 

 tapeworm. Areca-nut powder is unquestionably a good 

 vermifuge, as I can testify from personal experience; and 

 I observe that it is strongly recommended by " Stone- 

 henge " in his admirable memoir " On the Management 

 of Dogs." It is, however, rather as a taeniafuge than as
