222 The Management and Diseases of the Dog. 
paralysis in dogs seemed to be entirely due to worms 
(Field, March 15, p. 238). 
A great variety of anthelmintics have been recommended; 
but for this particular worm there is probably nothing 
better than castor-oil and santonine. As with the lumbri- 
coids 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 experiences 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 unquestion- 
ably a good vermifuge, as I can testify from personal 
experience ; and [ observe that it is strongly recommended 
by “Stonehenge,” in his admirable memoir, “On the 
Management of Dogs.” It is, however, rather as a teeniafuge 
than as a lumbricifuge that the merits of areca-nut powder 
stand out most conspicuously. The powder may be given 
in half-drachm or one-drachm doses, followed by castor-oil, 
and repeated twice or thrice in the day. In bad cases 
turpentine may be cautiously resorted to, and, when given, 
should be combined with twice as much either of castor or 
linseed oil. The dose of turpentine should be rarely more 
than one drachm, and in no case should it exceed two 
drachms in the very largest dog. Three drachms of 
turpentine have been known to occasion violent convulsions 
in the full-grown dog; and in the case of young puppies 
such a dose would probably prove fatal. Calomel, in one 
to three grain doses, is a favourite remedy with some ; but, 
considering its varied action, it should only be resorted to 
‘ when other remedies have failed. The mechanical irritants 
such as powered tin and glass, or even cowhage. should in
