The Association met at ten this morning, and
were busted for half an hour with the usual routine
business. A few slight alterations being made in
the record of the minutes,
The SECRETARY again suggested to gentlemen who
had papers for reading before the Society, that it
would prove matter of great convenience to have
them filed, and accompanied with an abstract for
the use of the Secretary in making out the minutes
Professor HITCHCOCK recommended that gentle
men would confne themselves to reading an epitome
OF their several treatises; they would probably be
numerous, and therefore time would scarcely permit
their being presented at length to the Society.
DIR. BARRATT read paper entitled Evidences of
Congelation in the Red Sandstone, exhibited by
regular triangular and rhombic marks, of great dis
tnctness." After noticing the bearing of this congo
laton question the temperature Of the earth, at
the earlier periods of animal life, and his finding ice
in the form of rhombs and triangles, in February,
l84l, he added. regard to the sandstone, that the
marks were produced by pressure Of lines in cor
responding figures when in soft state For long
time he had recorded every appearance OF ice tor the
purpose of throwing light upon the past action Of
congelatlon III the production OF these lmprlnts in
rocks. DR.. Barrett concluded by inviting gentle
men to accompany him to a building alluded to by
him, where certain marks were to be seen, in va
rious forms, and which he regarded as decidedly Of
an icy origin.
b. SILIlMAN, Jr arose to say that in certain soft
argillaccous beds in Pennsylvania he had observed
marks such described by DIR. Barrett, but he did
not ascrlbe It to the same causes, but rather regard
ed it the effect of which act in the forma-
| ton of such species of rocks.
Mr.. JOHNSTON thought that the rhomboidal struc-
ture talked of by Dr. Barrett was entirely distinct
from that alluded to by Mr.. Siliman.
The PRESIDENT asked Dr. B. he regarded the triangu.

Dr. BARRArr observed that he had anticipated some op
position and had taken to make long Of
neurological observations which he would be happy

Prof SULLIVAN glad to hear the remarks of Dr. B.
but thought that they could not afford SO much time in

He would move that the Chair should appoint commit
