A species of Rhus, which was frequent 

 in the marches here was called the poifon 

 tree by both Englifh and Swedes. Some of

 made into the tree, a whitifh yellow 

 juice, which has a naufeous fmell, comes 

 out between the bark and the wood. This 

 tree is not known for its good qualities, 

 but greatly fo for the effect of its poifon, 

 which though it is noxious to fome people,

 more experiments, with no inconvenience 

 to himfelf , another perfon on the contrary 

 dares not meddle with the tree, while its 

 wood is frefh, nor can he venture to touch 

 a hand which has handled it, nor even to 

 expofe himfelf to the fmoak of a fire which 

 is made with this wood, without foon
