other measures. Were this given a trial, the number of doses ought to be 
about five. After a fast of at least twenty-four hours, the same ending at night, 
a generous dose of castor-oil should be administered. As early as possible on 
the following morning the real treatment should commence with a dose of the 
salicylic acid, and persist until five doses have been given, with an hour be- 
tween each; and the last be followed, in the course of an hour, by a medium 
dose of castor-oil. 
Were the dog to be treated full grown and one of the largest breeds, each 
dose might consist of twelve grains; in which event the entire quantity taken 
would be sixty grains. For mature dogs of medium size, the dose would be 
ten grains; and for fox-terriers and the like, six grains. As for toys, this agent 
cannot be recommended because of certain peculiar effects; nor would it be 
advisable to administer it to puppies unless they were of advanced age. 
There seems firm ground for the belief that papain deserves a place 
among the drugs of great assistance in the removal of tape-worms. But un- 
fortunately it is very expensive; moreover, much of it on the market is nearly 
or entirely inert. Yet from reliable chemists a good quality ought to be 
obtainable. In what way it is unfriendly to these parasites is not known. 
Evidently it causes the heads to relax their hold on the intestinal lining, and 
doubtless this is the result of some quality which is poisonous to them, for 
several expelled by it have been found stupefied, but were restored and com- 
menced to uncoil when hot water was poured over them. 
Papdin, although of vegetable origin, has properties similar to those pos- 
sessed by pepsin and pancreatin. It should be given three times daily. The 
dose for dogs of medium size and largest breeds is ten grains; for fox-terriers 
and the like, five grains; and for toys, three grains. Each dose can properly 
be given in half a teaspoonful of glycerin and two teaspoonfuls of water. For 
the reasons assigned, papdin cannot be a popular remedy, nor indeed other 
than a remedial curiosity ; but still a discussion of tape-worm destroyers could 
not be complete were not at least bare allusions made to this and similar 
agents. 
The oil of turpentine, which acts best on worms in the stomach, in doses of 
sufficient size either kills or so weakens the tape-worm that it relaxes its hold, 
and is carried downward and out of the bowel. It is safe when properly em- 
ployed, and yet capable of grave injury; hence cannot be recommended for 
general use. Being highly irritating, it should always be administered in some 
other oil or thick liquid, or in the form of emulsion. The oil might be olive 
or linseed, or even castor-oil. It were better, however, that the last be not com- 
bined with it, but held for use about three hours after the turpentine has been 
taken and had opportunity to do its destructive work. An emulsion can be 
made by putting the quantity of turpentine to be used onto a plate with a 
goodly amount of powdered acacia, and rubbing them up until they are well
