The last month was remarkably dry, but the present si ill 

 more so, rain having fallen on 4 days only, and on these it was 

 very slight, scarcely amounting to T J T of an inch. In no month 

 has there fallen so limited a quantity tor the last fifteen years 

 at least. The barometer, though not so high as in the preced- 

 ing month, wss considerably above the mean. The temperature 

 was 2 0 above the average, which is to be attributed to the effect 

 of powerful direct solar heat, for the wind was seldom from 

 warm quarters, and the nights were frequently frosty, the clear 

 state of the sky being favourable to radiation. The difference 

 between the highest temperature in the days and the lowest at 

 nights averaged as much as 30 0 ; on the 13th it was 42°. Be- 

 tween the 24th and 38th the weather was extremely hot for the 

 period of the season. The dryness of the air on the 25th was 



Mean Pressure from the 3 daily observations 30.076 inches.
