[16] I have given details (the first, I believe, published) on
this subject in the first edition, and in the Appendix to it.
I have there shown that the apparent exceptions to the absence
of erratic boulders in certain countries, are due to erroneous
observations; several statements there given I have since
found confirmed by various authors.

[21] In the former edition and Appendix, I have given some
facts on the transportal of erratic boulders and icebergs
in the Atlantic Ocean. This subject has lately been treated
excellently by Mr. Hayes, in the Boston Journal (vol. iv.
p. 426). The author does not appear aware of a case published
by me (Geographical Journal, vol. ix. p. 528) of a gigantic
boulder embedded in an iceberg in the Antarctic Ocean, almost
certainly one hundred miles distant from any land, and
perhaps much more distant. In the Appendix I have discussed
at length the probability (at that time hardly thought of)
of icebergs, when stranded, grooving and polishing rocks,
like glaciers.
