. leprosy. According to that gentleman, Garjan Balsam when 
administered internally and at the same time applied to the 
Skin arrests the disease and promotes cicatrization of the 
ulcerating surfaces. In order to test the correctness of this 4

Description.—rhe freshly-drawn Balsam is an opaque 
grey fluid, which when placed in the sun gradually separates 
into two portions, the upper of which is a thick, viscid fluid of 
a dark reddish brown colour, and transparent when P
