TIertzian waves from lightning Casa

ing fact brought out is that the waves
from n great distance are practically
horizontal. but those from not mere

and OF chrome steel. used as abra9Ves.
Variations OF the process give such
compounds as white lead.
Electric tests have shown Professor
r. c. Bose that the pulsation in plaHts
is similar to that in man and animals.

The electric arc between iron po.es.
which has the popularity OF crater
but slightly luminous, is proven by a.
Broca and A. Chatin to be specially
adapted for medical use on account OF
the. great intensity of the actinic rays
as compared with the heat rays. This
makes it possible to bring the diseased
part within four inches OF an arc OF 20
aInperes and 35 volts. In nine cases Or

The suns philosophers is supposed by

I lar activity, and it is probable that
these waves give the added incandes-
