Artic. II. Of Camphors. 
Camphor a et Caphura , Off. Caphur * Arab. K «- 
ip* got, recent. Gracor. et Aetii . The Camphore of 
the Shops is a refinous, fattilh Subftance, growing 
fomewhat vifcid under the Teeth, white, tranfpa- 
rent, light, of an acrid, bitterifh, aromatick Talle, 
burning the Mouth, though with a certain Senfa- 
tion of Cold, and of a fragrant Scent like Rofe- 
mary, but more piercing and ftronger. It is fo 
very volatile, that being expofed to the open Air, 
it diminishes by little and little, and at length is 
entirely diffipated. It comes from Jap an , and the 
other neighbouring Hands. 
The Tree from which it is extra&ed is called 
Camphora Officinarum, C. B. P. 500. Arbor Cam- 
phorifera japonica , foliis Laurinis , fruflu parvo glo- 
bofo , calyce breviffimo , Breyn. 2®. Pro dr. et Hort . 
Amftel. [Lanrus foliis Ovatis , utrinque acuminatis , tri- 
nerviis , nididis , petiolis laxis , Lin. Hort. Cliff. 154.] 
In order to procure this Refin, the Wood and 
Root of the Tree are cut into fmall Pieces, and 
boiled in an Iron-Velfel with a certain Quantity of 
Water. The Veffel having a Cover of Straw 
fitted upon it, the Camphore rifes up by Decoc- 
tion, and concreting upon the Straw like a white 
Soot, is fhook off and compa&ed together into a 
Mafs, which feems compofed of many femi-tranf- 
parent, gray, reddifh, or yellowifh Grains, having 
yet a confiderable Mixture of Earth and other Im~ 
R purities.
