PART III. 

 SPECIAL THERAPEUTICS. 



ON THE VAEIOUS MEDICINAL AGENTS EMPLOYED 

 IN THE TREATMENT OE INTESTINAL AND 

 OTHER ENTOZOA. 



In the preceding chapters the plans of treatment 

 for the different species of intestinal worms, and the 

 best medicines which can be used for their expulsion, 

 have been indicated ; but the remedies winch have, 

 from time to time, been employed have not been 

 fully described. They will, therefore, be now dis- 

 cussed at greater length. 



It would be useless to give an account of the 

 anthelmintics which have received a trial at the 

 hands of various observers ; as their number is very 

 considerable, and the majority of them really possess 

 no special vermifuge properties. Leclerc, in a work 

 published at Geneva in 1715, furnishes a tabular 

 statement of anthelmintics commonly known in his 

 time ; of these, 379 remedies were obtained from the 

 vegetable kingdom, 27 from the animal kingdom, and 

 13 from mineral substances. If all of the remedies 

 which have, since that period, been tried and sug- 

 gested, were enumerated, they would probably be 

 found to amount to double the number mentioned 

 by Leclerc.
