3. General Observations; all Fresh-water Fishes of

been created where they now live-Deductions
from this fact,

VII. Glacial Theory of the Erratics and Drift of the New
and Old Worlds. By Professor AGASSIZ :-
Glacialists and Antiglacialists.-Erratic basins of
Switzerland. Similar phenomena observed in other
parts of Europe.-Points necessary to be settled;
first, the relation in time and character between the
Northern and the Alpine erratics.—Traced in North
America. Not yet settled whether any local centres
of distribution in America; but the general cause
must have acted in all parts simultaneously. This
action ceased at 35° north latitude; this incompatible
with the notion of currents.-In both hemispheres a
direct reference to the Polar Regions. Difficulty as
to so extensive formation of Ice, removed; difficul-
ties on the theory of Currents, the effects contrary
to experience of Water-Action.-Erratic phenomena
of Lake Superior.-The Iceberg theory.-Descrip-
tion of appearances at Lake Superior.-Drift: con-
tains mud, and is without fossils.-Example of
juxta-position of stratified and unstratified Drift, at
Cambridge.-Date of these phenomena not fully de-
termined, but doubtless simultaneous all over the
Globe. The various periods and kinds of Drift dis-
tinguished.—Accompanied by change of level in the
