ANTHELMINTICS. 2t 



however, that tin has not been fairly tried ; 

 and as it is an efficacious anthelmintic in 

 dogs, it may probably be found useful in 

 horses*. Of all the mercurial preparations, 

 calomel is by far the best for this purpose, 

 and may be given with aloes, soap, and 

 some aromatic oil, with a little ginger* 

 Many prefer giving the calomel at night, 

 and the purgative the following morning. 

 Aloes are a good anthelmintic, particularly 

 when mixed with a small proportion of 

 gamboge. Arsenic has been very fairly 

 tried, and does not seem to possess any an^ 

 thelmintic power. A saline substance has 

 been lately introduced from India, as a 

 remedy for that species of worm, termed 

 botts. It seems to be composed of common 

 salt and liver of sulphur, and is named sal 

 indus. It does not appear to deserve the 

 character that has been given of it ; though 

 like salt or brine, it will sometimes cause 

 the common or intestinal worm to be eva- 

 cuated. 



* I have lately had an opportunity of trying the 

 efficacy of Tin, as a worm medicine ; it sometimes 

 destroys them, but not uniformly j and appears 

 to b€ more effectual when joined with Calomel.
