RESULTS. 

 Winds : N, 1 ; NE, 9 ; SE, I ; SW, 4 ; W, 1 ; NW, 14. 



Barometer: Mean heights (the extremes are at the foot of the 



table) : 



For the month 30 . 051 inches> 



For the lunar period (beginning with the day of the 



third quarter, and including the observations of 



the last table) 29*992 



For 12 days, with the moon in south declination 



(ending with the 12th inst.) 30*01 6 



For 15 days, with the moon in north declination 



(ending 27th inst.) 29*998 



Thermometer: Mean heights (the extremes are at the foot of the 

 table) :

For 31 days with the sun in Cancer 63*84 



Hygrometer: Mean for the month at 9, a. m 63 



Evaporation for the month 3*80 inches. 



Rain 1*45 



The rain appears to have fallen chiefly about New and Full Moon, and in nearly 

 equal proportions to each. This is the sum of products afforded by a gauge placed 

 about eight feet above the ground : another on the ground gave 1*60 inch, and this 

 will be employed in future. The character of the month was decidedly that of 

 fine weather. A previous cloudy season having kept the sky obscured at night, a 

 splendid comet, which must have been for several days near enough to us to be 

 visible, disclosed the secret of its presence on the night of the 3d, and was scarcely 

 afterwards seen in this neighbourhood to greater advantage than at this its firs! 

 appearance.
