WONDERS OF LIQUID AIR
LARGO AUDIENCE LISTENS &c
PROF. F0STERS LECTURE.

AAS1's N US AAGLS
Prof. Eugene c. Foster delivered an
absorb.ngly ente tanning lecture last night
at the Peoples church on Liquid Air.
Prof. Fosters audiences have been of
the largest, and the attendance at the
Peoples church last night was no excep-
ton to the rule.
All the apparatus for the experiments
to be performed during the evening was
placed upon tables on the front of the
rostrum. When Prof. Foster made his
appearance he took glass from one Of
the tables, had it filled with liquid aid
by the boy who assisted him, and sprin-
kled it upon the floor. The liquir iname-
diately disappeared in a cloud Of white
vapor, apparently, but which was in real
1ty miniature snow storm. Prof. Foster
then said:
Before 1 begin with my experiments I
want to make a few preliminary re-
marks. I have found in my travels over
the country that many people have diff
Guilty in believing that there is such a
thing as liquid air. Some even suspect
me Of beng possessed OF a little of Her
mann's cleverness.a a That idea must be
dispelled. This substance have here is
really liquid, and, generally, it can be
handled with impunity It looks ahout
IKE water, and has blush tint, and is
OF ABOUT the same weight as water
Liquid air is a comparatively recent
discovery. 1t was made as early as 1877
IN 1893 1t was made in fairly large o11an-
titles. AT the present time we can mako
1t by the gallon or keg Or barrel, and at
comparatively small price 1 say com
pdFatIVely small price because it costs
ABOUT 20 gallon. The first ounce that
was made cost 81, 600 or more.
