It obvious that means devices of

practical advantages which may derived
from inclosing the terminals contacts a
closed receptacle are readily realized the
fullest extent.

. The rate rotation of
the wheels depends upon the rate of
5 relative movement the mercury, and hence
if the mercury caused flow one direc
tion and the wheels carried bodily the
opposite direction the rate rotation, and
consequently the frequency the makes and
io breaks, will very greatly increased over
that which would obtained the wheels
