1 During three days nothing very remarkable 

 in the weather, the ordinary hot wind of 

 the season blowing. 



1st. Wind very strong and rather gusty, almost 

 a gale, during the night shifted to East and 

 blew fresh; 9 30 of 2nd wind at South, 

 shortly afterwards backing to East, at which 

 it continued steady. 



3rd. Cloudy during forenoon. 



5th. Cloudy and rain drops in morning ; at 5 

 p. m. wind to S. with squalls and again settled 

 at Westward. 



6th. Shower for two minutes from N. W. at 

 noon. 



The temperature is taken in a room, where is neither punka nor 

 tatties; the direction of the wind in the tables is that at the time of ob- 

 servation, and may not be correct to a point, but it is nearly so. Of the 

 shift on the night of the 1st, I can give no further account than I 

 have entered in my notes. I was struck with it at the time as curi- 

 ous, succeeding to such a strong N. W. wind with a falling glass. 



I commence the tables from the 28th ultimo, to shew the steady 

 fall of the Sympiesometer. On that day it stood at the average for the 

 month ; viz. 29° 08' a. m., and 28° 93' p. m., the day before, however, 

 it was as high as 29° 04', and after the 6th, it continued to rise till the 

 11th, when it reached 29° 15', and has since gradually fallen to about 

 29, indicative I hope of the approach of the rains. As Agra is about 500 

 feet, (I believe) above the sea, allowance must be made for that height 

 in comparing these tables with others ; to aid this, I give the average 

 for the month of April here compared with the same in Calcutta ; 

 should a longer series of averages be desirable, I can give you the 

 same for two years nearly.
