RESULTS. 



Winds variable, the South-west most continuous. 

 Barometer: highest observation 3040 inches; lowest 29/32 inches- 

 Mean of the period 20/88I inches. 



Thermometer: highest observation 75°; lowest 39 ; 

 Mean of the period 55-37°. 

 Evaporatiou 4-09 inches. Kain 2-81 inches. 



This period is remarkable for being pretty equally divided into a dry 

 and a wet moiety : the former commencing with the first quarter, the 

 latter the day before the last quarter of the moon. The return of the 

 first quarter appears (by subsequent observations) to have again nearly 

 coincided with that of dry weather.
