Sabine’s magnetic “ decennial period,” and Schwabe’s period of 
solar spots. 
The law of varying attraction suggests a plausible explanation 
for the approximate mean proportionality of the barometric 
the tidal and magnetic variations, For the ratios of attraction 
of any planet when in solar conjunction, at quadrature, and in 
Opposition, vary as (x + 1)?, n?, and (n— 1), respectively, the 
attraction at the mean distance being nearly a mean proportional 
tween the maximum and minimum attractions. he barome- 
trical fluctuations are occasioned by variations in the gravitation

Ing to my hypothesis, by the oscillations of the air and ether in 
their efforts to restore the unsettled equilibrium, The three dis-

equal in amount but diametrically opposed in direction, This
