Prof. BRocKIEsBY read paper infinitely describ
ing several rems ksbe instances Of frozen wells three
al Owego in of which the ice was two feetthck 10
March: ole in Otis Berkshire County, Mass, and one
in Brandon. In all the water came through gravel,
and generally it WAS shallow.
Prof LOOMS thought il less strange that some
wells sbonid freeze than tina. all shonld not The
coM AIR in Winter would Of course flow down in
10 the well and if there WAS no circulation between
the wser in the well and that of the surrounding earth

Prof. HoRsroRD, in a paper on the alleged occur

Prof HoRsruRD read another psper showing that
as pe arls were formed by the previous formation OF
carbonate Of ammonia through injury, int ANIMATION
and putrefacon the carbonate of lime IN the coral
results from double decomposition OF the carbonate
Of ammonia residing from the decowposiVon Oh
minnie sea animals and the suphste Of lime in the
water. He concluded with comparing water
taken from the Gulf Stream between Florida and
Havans, with that taken off Boston liaroor. Inc
southern water was more dense, as might nave peen
expected than the nor hern. 90
After a short paper by Prof. MALLET, Mr.. t.
STERRY HUM suggested that the carbonate OF lime
for corals mig ht have been furnished by the decompo
sion Of the carbonate Of soda which was carried into
the ocean by many rivers from alkaline springs
