ON THE JESUITS' BARK-TREE. 3,><) 



outside, though in some rough and scabrous. When well 

 dried, the inside is of a dark-brown colour. Its flavour at 

 first is sweet, with a mixture of the taste of horse-radish, and 

 of aromalies of the East ; but when swallowed, of that very 

 bitterness and astringency which characterises the Peruvian 

 bark. It yields these qualities strongly to water, both when 

 cold, and in decoction. Half an ounce boiled, from two 

 pounds to one pound of water, made as strong a decoction as 

 three times its weight of the Cinchona vera. The colour was 

 brown, but not turbid. 



I have had many opportunities of trying its effects, espe- 

 cially in remittents, which are the most common and fatal fe- 

 vers in these climes. A vomit, or gentle purge, if necessary, 

 was first given ; and then immediately this bark, as soon as 

 they operated. I observed that it strengthened the stomach, 

 checked retching and vomiting, corrected morbid humours in 

 prima: vice, and conquered speedily the disease. My success 

 in such a dangerous malady, leaves not a doubt on my mind 

 but that it will prove equally efficacious in every other case, 

 where a tonic and antiseptic medicine is indicated.
