ppendix; probably, therefore Mr. Darwin's notes were
published separately as a paper in the "Phil. Mag.") I wonder whether
the "Phil. Journal [Magazine?.]" would publish it, if I could get it
from Ramsay or the Geological Society. (502/3. "On the Power of Icebergs
to make rectilinear, uniformly-directed grooves across a Submarine
Undulatory Surface." By C. Darwin, "Phil. Mag." Volume X., page 96,
1855.) If you chance to meet Ramsay will you ask him whether he has it?
I think it would perhaps be worth while just to call the N. American
geologists' attention to the idea; but it is not worth any trouble. I am
tremendously busy with all sorts of experiments. By the way, Hopkins at
the Geological Society seemed to admit some truth in the idea of scoring
by (viscid) icebergs. If the Geological Society takes so much [time] to
judge of truth of notions, as you were telling me in regard to Ramsay's
Permian glaciers (502/4. "On the Occurrence of angular, sub-angular,
polished, and striated Fragments and Boulders in the Permian Breccia
of Shropshire, Worcestershire, etc.; and on the Probable Existence of
Glaciers and Icebergs in the Permian Epoch." By A.C. Ramsay, "Quart.
Journ. Geol. Soc." Volume XI., page 185, 1855.), it will be as injurious
to progress as the French Institut.

LETTER 503. TO J.D. HOOKER. Cliff Cottage, Bournemouth, [September] 21st
[1862].

I am especially obliged to you for sending me Haast's communications.
(503/1. "Quart. Journ. Geol. Soc." Volume XXI., pages 130, 133, 1865;
Volume XXIII., page 342, 1867.) They are very interesting and grand
about glacial and drift or marine glacial. I see he alludes to the
whole southern hemisphere. I wonder whether he has read the "Origin."
Considering your facts on the Alpine plants of New Zealand and remarks,
I am particularly glad to hear of the geological evidence of glacial
action. I presume he is sure to collect and send over the mountain rat
of which he speaks. I long to know what it is. A frog and rat together
would, to my mind, prove former connection of New Zealand to some
continent; for I can hardly suppose that the Polynesians introduced the
rat as game, though so esteemed in the Friendly Islands. Ramsay sent
me his paper (503/2. "On the Glacial Origin of certain Lakes in
Switzerland, etc." "Quart. Journ. Geol. Soc." Volume XVIII., page 185,
1862.) and asked my opinion on it. I agree with you and think highly of
it. I cannot doubt that it is to a large exten
