DISCUSSION.
A brief discussion followed the reading OF the
paper. in which Aessrs. Richardson, Chesprough,
Colbert pr. Andrews, and Judge Caton took
part. Mr. Clesb1 ough suggested that perhaps
the irregularities in tue fow, mentioned By Judge
Cation, were caused by loose fragments of rock
| getting into the natural cbanpels OF INe wells,
| aud impeding the course Of the water.
CREATION OF EVOLUTION
! L paper on the - Creation OF Evolution " was
| then read by Prof. Delafontaine. 1t was q long
essay il defeuse Of DarNinit1n, and in opposl-
| ton to the theories Of creation entertained by
| the late Prof. Agassz and other eminent sci-
| entists.
THE PENDULUM EXPERIMENT..
! Mr. Elias Colbert read snort paper on the
| proposed pendulum experiment. bo said the
| Exposition building offered tine opportunity
| for repeating the experiment by which it WAS
demons; ;1ated that the earth turned round on her
| axis daily. It was twenty-threo years since II.
| Leon Foucault suspended ls pendulum from
{! the done Of the Pantheon. in Paris. and set tho
| scientific world in blaze OK excitement.
| The experiment had been repeated in many Of
the cities OF Europe, and at TWO or three points
in the Eastern States, but it had never been
| tried in the West so far as the speaker knew.
The Directors Of the Exposition Building had
signifed their willingness to let it be used for
! the experiment, and it was the duty OF the
Academy to take some action in the matter, and,
| if possible, let the people have ocular demon
stration that the world really did move, as thoy
they had been taught to believe ut SCHOOL
| The General Committee Was instructed to at
