The terebinthina veneta, or more properly called larigna (as we are 
not wholly fupplied with this article by the Venetians) iflues fpon- 
taneoufly through the bark of this tree, but is more commonly obtained 
by wounding the bark at the diftance of about two feet from the 
ground, and inferting in the wound a fmall canula, through which the 
turpentine flows into proper vefTels, which are placed for its reception. 
This turpentine is ufually thinner than any of the other forts, of
