The data of this table are not of much importance in connection 

 with the present discussion. They shew that the average decrease of 

 temperature with elevation (as determined from day and night observa- 

 tions) varies from 1'9° per 1000 feet in the North- West Himalayas to 3*3° 

 per 1000 feet in Beluchistan and Sind, where the general climatic con- 

 ditions at that time are apparently very similar to those of the Punjab. 



The following table gives the average daily range of temperature at 

 the plain and hill stations of each pair of stations.
