The equivalent thus deduced is far greater than that brought out 

 by the Sikkim observations. It indicates a considerably higher 

 temperature of the atmosphere, and is probably attributable to the 

 evolution of heat during extraordinary rain-fall, and to the formation 

 of the surface, which is a very undulating table-land, and everywhere 

 traversed by broad deep valleys, with very steep, often precipitous 

 flanks ; these get heated by the powerful sun, and from them, 

 powerful currents ascend. The scanty covering of herbage too over 

 a great amount of the surface, and the consequent radiation of heat 

 from the earth, must have a sensible influence on the mean tempe- 

 rature of the summer months.
