On Grass 





The rapid drying of the lower strata of the atmosphere during 

 the day, as indicated by the great decrease in the tension of the 

 vapour from 9 a.m. to 3 p.m., is the effect of the great violence of the 

 north-west winds. 



From the few days' observations taken on the Kymore hills, the 

 temperature of their flat tops appeared 5° higher than that of the 

 Soane valley, which is 500 feet below their mean level. I can 

 account for this anomaly only on the supposition that the thick bed 

 of alluvium, freely exposed to the sun (not clothed with jungle), 

 absorbs the sun's rays and parts with its heat slowly. This is 

 indicated by the increase of temperature being due to the night and 

 morning observations, which are 3°.l and 8°. 5 higher here than 

 below, whilst the 9 a.m. and 3 p.m. temperatures are half a degree 

 lower. 



The variations of temperature too are all much less in amount, as 

 are those of the state of the atmosphere as to moisture, though the 

 climate is rather damper. 



On the subject of terrestrial radiation the paucity of the observa- 

 tions precludes my dwelling. Between 9 p.m. and sunrise the 

 following morning I found the earth to have lost but 6°. 5 of heat, 

 whereas a mean of nine observations at the same hours in the valley 

 below indicated a loss of 12°. 



Though the mean temperature deduced from the few days I spent 

 on this part of the Kymore is so much above that of the upper Soane 

 valley, which it bounds, I do not suppose that the whole hilly range
