It is wonderful, that the bark of Loxa {Cinchona officinalis) iliould 

 have been called in Europe, and every other part of the world 

 except its native place, by the name of ^uina-^uina, which, name 

 properly belongs to the tree we are mentioning, always called §>uina- 

 £>uina by the natives, and afterwards by the Spaniards when they 

 firft became acquainted with it. Among the feveral virtues attri- 

 buted to this tree, the molt confiderable is that of its bark, which 

 paffed for an excellent febrifuge, and before the difcovery of the 

 tree of Loxa was in great repute for curing tertian agues, &c. The 

 jefuits of La Paz or Ghucuyapu gathered its bark,, which is ia- 

 tenfely bitter, very carefully, and ufed to fend it to Rome, where 

 it was diftributed under the true name of ^uina-^uina, and ufed 

 for the cure of intermittent fevers. It feems that the bark of 

 Loxa having palled into Europe, particularly to Rome, by the 

 fame means, the new febrifuge has been confounded with the old 

 one, and that of Loxa having been mod ufed, has retained the name 

 of the firft> which is now-a-days. almoft entirely forgotten. The 

 name Cafcari/la, or fmall bark, given to that of Loxa, feems to have 

 been invented in order -to diftinguiih it from ibme other, undoubt- 

 edly the ancient £{ui?ia-£>r/.ina.
