THERE is a famous tree, befides the Peruvian bark {Cinchona 

 officinalis of Linnaeus), known in feveral provinces of South 

 America under the name of ^ina-^inaf and in the province of 

 Maynas on the banks of the river Marannon under that of Tatchi, 

 A fragrant refin diftills from the trunk by means of an incifion. 

 The feeds, called by the Spaniards Pepitas de ^ina-^tina, have the 

 form of beans, or of flat almonds, and are enclofed in a kind of 

 doubled leaf, between which and the feed is found a little of the 

 fame refm that diftills from the tree. Their chief ufe is to make 

 fumigations, which are reputed cordial and wholefome, but their 

 reputation is much lefs now than formerly. 



This tree grows plentifully in feveral provinces of High Peru, as 

 in the neighbourhood of Chucuifaca or La Plata, Tarija, Mifque, 

 Lipes, &c. The natives make rolls or mafles of the refin, which 

 they fell at Potofi and Chucuifaca, where they ferve not only to 

 fumigate or perfume with, but alfo for feveral other ufes in phyfic, 

 fometimes under the form of a plaifter, fometimes under that of a 

 compound oil made from the refin. This fxibftance is fuppofed to
