of the Aurora Borealis,’’ p. 220). Lovering observes that the days sig- 
nalized by the frequency of these phenomena are also days which, accord-

stars. Ihave grouped the second means of Baumhauer’s numbers in 
five-day periods, and calculated the ratio of each ordinate to a mean or- 
dinate of 100, in order to justify the following comparison with the auroral 
ordinates, which were similarly computed from Lovering’s table. 1
