From the Finnish Observatory at
Sodankyla there comes an important fact
to students of the electrical condition Of
the earth. Professor s. Semstrom had

vanic battery, with conductors covering
an'area of 900 square meters. Soon the
cone was found to be surrounded with q
halo. This effulgence was of yellow.
white color, and it gave family, but per-
fectly the spectrum Of the aurora borealis.
Further experiments confirm the accu.
