what else was done before adjournment
PROT AGA,siZ referred % the general charac
ter OF the Black banded CyPrina9 Tie said the colors
ton and marking (the black bands OF these animals
goes nothing at all when we md that these bands
Usually considered characteristic OF the species are
only observable in the young animal, and as It grows
the bands fade away
PROT A. continued by remarking that he had found
il necessary to separate the Cyprinlde from those
fish which he calls Cyprn0ddnts,-the two animals
dsrin, in this the former having additional tuber
Gle behind the cerebelum but the CyprlnOdants have
a simple brain without the tuocrcle
Dr. GlBBEs presented 10 the notice OF the Con-
vention remarkable Fossil specimen from the Green
sand formation of New. j. reey Dr. q. moved that 1t

This Section sat to-day only in the morning
being merged in the other in General Meeting in the
afternoon.
The Chair was taken by LET MAURY aud the Section
proceeded to business by listening TO an oral eommun

WAS principally blackboard illustrations, and in the de-
tails excited considerable discussion. Several hypo
theses were developed, which elected analytical re-
marks by Prof Henry, Hare conn oil IA SHhMan'

sufficient that those relations should be supposaols and
that the certainty OF Mathematical reasoning rested
