OF Eve on Light, wrs delivered By Mr.. IT, q
Taylor on Wedcesday evening, December 20
in the large hall Of Institute, and notwith'

attended, eyincing the increased interest ioi
this department as felt BY our citizens. In the
course Of the lecture Mr.. Taylor introduced the

The sparks or current In passing from pole to

feet long, raised II to a white heat which be-

20 inches. This was explained on the undula

Of the atoms of the wire CAUSED by the passage
Of the electric current. The wires Of the bat

Mr.. Taylor Rlluded to Phosphorescence as a
source OF light. II is that property possessed
by FIRE. flies, glow-worms, &C., which Ia some
countries are gathered by the natives in bottles
for the purpose OF illumination.

lectures are illustrated by highly interesting
experiments, and those with any desire for IN
and ussfu scientific knowledge should
not fail TO attend them. The committee upen
their part and Mr.. Taylor 90 his have gone to
c considerable trouble and expense to make these
lectures aud attendant experiments successful
Ia every way and they must both be highly

will no doubt be instructive aud interesting AS
heretofore and amusing also as in some OF the
illustrations some very funny effects will be
produced.

instance OF INDIGESTION we ever heard OF was
that of the man who sat up all night because
he could not decide which TO take OF first, his
coat or his boots. Any one patronizing Charlie

not remain long undecided concerning the
merits of the cheer his liberality affords. His
