A Second EvsainE In Wonderland.
The second complimentary exhibition
was given last evening by the Lancaster
Microscopical society, in the high school
building on West Orange street, to . select
number Of the pupils OF the boys depart
ment Of said school who had not been
present ut the previous exhibition. and
number Of the teachers employed in the
pnblic schools. An invitation had been
extended by Prof. Buerhle to the various
classes in order below the first in the girls
high school, bnt nobody in any Of these
classes wished to attend. Perhaps the
girls We're not sufficiently awake to the
wonders Of nature to appreciate such an
exhibition. or it may be that they were too
busy with their Christmas preparations to
think Of anything besides. At all events
their absence made room for number Of
teachers who were greatly interested and
heartily enjoyed the profitable evening.
The object Of the society is to popular
ize the use Of the compound microscope,
and to diffuse some knowledge Of the won
ders of mature, rs means Of promoting
the study Of natural sciences. Judging
from the result Of their efforts, this OBJ
ject is in \ fair way Of being accomplished
in some small degree ut least, for q more
interested company Of pupils and teachers
than those in attendance last evening it
would be hard to find. The boys espe-
cially distinguished themselves rs close
observers and showed remarkable indus
try in taking notes Of what was exhibited
with view to writing out ian account of
what they SAW and how it impressed them,
that being the condition upon which tick
cts had been given them.
