They form the principal source of a river, which empties itself into the 
Burrampooter, near Tissoolumboo. 
The wind from the eastward of south, was now the coldest and most 
piercing; passing over the snowy mountains, and dry sandy desert 
before described, it comes divested of all vapour or moisture, and pro¬ 
duces the same effect, as the hot dry winds in more southerly situations. 
Mahogany boxes and furniture,-that had withstood the Bengal climate 
for years, were warped with considerable fissures, and rendered use¬ 
less. The natives say, a direct exposure to these winds, occasions the 
loss of their fore teeth; and our faithful guide ascribed that defect in 
himself, to this cause. We escaped with loss of the skin, from the 
greatest part of our faces. 
September 18. Road to Seluh.y. Near our road to-day found a hot- 
well, much frequented by people with venereal complaints, rheu¬ 
matism, and all cutaneous diseases. They do not drink the water, but 
use it as a bath. The thermometer, when immersed in the water, rose 
from 40° to 88°: it has a strong sulphurous smell, and contains a por- 
tion of hepar sulphuris. Exposure to air deprives it, like most other 
mineral wells, of much of its property. 
September 19. Road to Takui . z Passed some fields of barley and 
pease, and got into a milder climate. Found, to-day, a great variety 
of stone and rock, some containing copper, and others, a very pure 
rock-crystal, regularly crystallized, with six unequal sides. The rock- 
crystal is of different sizes and degrees of purity, but of one form. 
Found some flint and granite, several springs of water impregnated
