TABLE XLIII. — Quantity of Rain with reference to the Moon's Age. 



The results for the greenhouse-gauge are deduced from observations from March 6, 1837, till April 9 

 1842, including 62 lunations. The results for the observatory-gauge are deduced from observations from 

 July 7, 1842, till July 28, 1848, including 75 lunations.

The results for the two gauges differ. By the greenhouse-gauge, the greatest amounts of rain fell when 

 the moon was both new and full, and the least fell at the quadi-atures. It is right to state, that much confi- 

 dence could not be placed in any result from this gauge, since it is sheltered from NE. winds by neighbouring 

 trees, and its position upon the ridge of the greenhouse-roof seems to unfit it for even relatively accurate 

 determinations ; as the summations were made for this gauge, it has not been considered proper to withhold 

 them. By the observatory-gauge, the greatest amount of rain fell about thi-ee days after new moon, and the 

 least fell at full moon ; the same result is obtained from the sums for both gauges. The result for the obser- 

 vatory-gauge is very distinctly marked.
