The upper course of the Soane heing in some places confined, and in 

 others exposed to furious gusts from the gullies of the Kymaon hills, 

 below Kotah, bounded by a continuous precipice of 1000 feet, and above 

 it expanding into a broader and flatter valley, presents many fluctuations 

 in temperature. 



Exposed to the influence of radiation from so extended a surface, the 

 mean temperature is much above that of the lower parts of the same 

 valley (below Tura) the excess amounting to 5°. 4. The nights and
