Recurrence of rain — The relation between the moon's motion in declina- 

 tion and the quantity of rain in New South Wales, H. C. Russell {Jour, and 

 Proc. Boy. Soc. New SuuUt Wales, 35 {1901), pp. llS-llo). — kn analysis of rainfall 

 records is made which indicates that rainfall is abundant "when the moon is in 

 certain degrees of her motion south, and when the moon begins to go north then 

 droughty conditions prevail for seven or even eight years, a phenomena repeated for 

 three periods of nineteen years each." The author believes that there is a law con- 

 necting the t\V(i phenomena.

 Assoc Adc. >S'c/., 1901, p. 603). — From an analysis of observations on the chlorin con- 

 tent of rainfall it "clearly appears that minimum amounts of rainfall are marked by 

 maxima of chlorin contents, and vice veisa."
