they penetrate more readily to the bottom of the wound. From 

 the experiments of Dr. Barry, Professor Mangili, and others, it 

 appears that the application of cupping-glasses, as prescribed by 

 Celsus, is a remedy which may prove extremely useful in all cases 

 of bites inflicted by venomous animals. 



With respect to the general measures, experience has shewn 

 that medicines of a stimulating nature are best calculated to 

 remove the powerfully depressing influence that is exerted over the 

 nervous and circulating systems, by this class of animal poisons. 

 The volatile alkali, spiritus ammonioc succinatus, sulphuric ether, 

 and oleum terebinthinse, are the remedies usually employed. Of 

 these the liquid ammonia, administered internally, in the dose of 

 from fifteen to twenty drops, every two hours, is generally regarded 

 as having the best title to the character of a specific for the bites 

 of venomous serpents. Tn South America, where venomous 

 snakes are very numerous, the expressed juice of the Mikania 

 guaco, a plant described and figured by Humboldt, is generally 

 esteemed as the best remedy for the bites of poisonous serpents. 

 The roots of Polygala Senega, Aristolochia serpehtdria, ahguidida, 

 and longifbtia, Prenanthes alba, and the bark of the tulip -tree, arc 

 also recommended.*
