Lecture Bef0Fe fhe Cooper Union Association
for the Advancement Of Science and Art.
DR.. J. +. Boynton delivered lecture last evening
before q large audience In the great nall Of the
Cooper Institute, taking as his subject 1.-THE Earth
and the Moon.n This was the second OF course Of
six lectures on the natural history OF creation, un.
der the auspices OF the Cooper Union for the Adj
vancement OF Science and Art, snd was illustrated
by q succession OF admirable VIEWS, developed ON
canvas by the stereopticon.
Mr. Hewitt Secretary OF the Institute, prior to the
delivery OF the lecture announced that II was the
intention OF the trustees, as this course was
completed to give series OF FREE scientific and phi.
losophica lectures on Saturday evenings throughout
the winter, and the announcement was greeted with
hearty applause by the audience.
DIR. Boynton after few remarks Introductory to
his general theme, said that all matter with which
are acquainted was susceptible OF being divided
until the particles became small that tho eve
could not discern them and, even when assisted by
the microscope could not estimae their size. There
was no substance that. under certain circumstance
could not he rendered Invisible, or reduced to the
condition OF vapor. steam even gases. And 80
the substances which enter int the composition OF
the earth were once In state ~ vapor OF gas, but
10y cooling and various other CHANGES had become
condensed into the solid or liquid or case
Gus substances which we ind upon our
earth. And union Of these PARTICLES had resulted
IN the formation Of large bodies, the sum- earth
and moon and other planets, Until their united dr.
mensions were beyond our power OF realization or
conception planet like ouB thrown into one Of
