Influence of the Moon on the Barometer. 



[MaV, 



Nearest full moon, 9 days,- 7 hours ; or 2 days, 7 hours' distance from the 

 depression. 



The minimum depressions of the remaining years are still higher, and irre- 

 gularly placed with regard to the moon's declination, as follows :

Nearest full moon, 24° 9', or nearly 2£ days, distance from depression. 



There are yet some further minor depressions, which we must not omit, as 

 though they are not the minima of any particular years, they are much lower than 

 some of those we have been considering. I subjoin the details of all under 

 29-300 inches.
