nation being however to the south instead of the north. Quartz 
rock is the most prevalent here. The hot spring alluded to is distant 
500 or 600 yards from the river, and rises out of the level ground 
about midway between the ridges. At the time I visited it in 
November last, it was running in a full stream, but before and 
during the early part of the rainy season, I vras told it is always 
dried up, and when low indicates merely the common temperature. 
I found the sensation of heat intolerable when the hand was 
immersed in it, and Fahrenheit’s thermometer stood at 140 degrees 
at all parts, as well near the surface as within a few inches of the 
bottom. Excepting the increased temperature, this water possesses 
no sensible properties different from rain or common spring water; 
it is clear and tasteless, and although I had not the means of apply- 
ing chemical tests, I have since learned from a friend who made the 
experiment, that these indicated no peculiar impregnation. Gas 
was constantly disengaged from the surface in large bubbles, which 
I attempted in vain to collect. Many virtues are attributed to the 
waters of this spring in the cure of diseases ; and the Brahmans, 
who wait on it, derive considerable emolument from the crowds 
which resort thither for relief. I could discover nothing peculiar in 
the local situation of this fountain, or in the nature of the soil out 
of which it flows. The adjoining district, which was under 
cultivation, seemed to be a strong clayey loam ; and then bore 
flourishing crops. On leaving Monghyr, the country becomes 
again flat, and we meet with no rock on the banks of the river for 
upwards of 200 miles, until we reach Chunar ; at this place several 
low ranges are seen running in a similar direction to those below 
Monghyr. The hill, from which the specimens were procured, 
appears to be the termination of one of these ; it rises, with a 
gradual diminution of its circumference, to the height of several
