of country from Bahar to the foot of the hills con-

towards the foot of the hills, of a very good fort, and bearing 
much fruit. Saw a few lime-trees, and found three different 
fpecies of the fenfitive plant. One fpecies is ufed medicinally 
by the natives of Bengal in fevers ; it is a powerful aftringent 
and bitter; another is the fpecies from which Terra Japonica is 
made, a medicine the hiftory of which we are but lately made 
acquainted with. The third fpecies is well known as the fen-
