j. sUNspOTS AND RAINFALL.
A pamphlet has recently been published By
Irof. Archibald, Of Patna, on the rainfall Of the
world IN connection with the cloven.ycar period
Of sunspots. The author Is an ardent advocate
Of tt,s modern theory Of tho existence OF stch
aid ho statas hEt views very clearly
10 the present paper. We mar say that bis idca
Ii that tho minimum OF snuspot frequently cor
responds to maximum Of terrestrial tompcra-
ture, md he Is thus 10 accordance with DR.. r. q.
Hahn and BONO other European, as distinguished
from English, physicists who hare dealt with
The question. Not only does Prof, Archibald
cnlcavor to prove the existence Of the rein

pruof. Tho most Interesting portion Of the
inper Is tho explanation nf the reasoa why some
Rtatlono afford results as to pertodfcty Of rat,-
