 ba\'e L;i\'en snnie facts on (he trans] mrtal of 

 erratic Ijouldcrs and icelicrgs in the Antarctic 

 Ocean. This subject has lalLly l)ecn treated 

 excellently liy Mr. Hayes, in the Boston Joiirmi} 

 (vol. iv. p. 426). The author docs not appear 

 aware of a case published by me {Gcoi^raj^luial 

 JouDtal^ vol. i\'. p. 528), of a gigantic liouldei 

 embedded in an iceberg in the Antarctic Ocean, 

 almost certainly one hundred miles distant 

 from any land, and peihaps much more distant. 

 In the Appendix I have discussed at length the 

 ]irobability (at that tnne hardly thought of) of 

 icebergs, when stranded, grooving and polishing 

 rocks, like glaciers. This is now a veiy com- 

 monly received opinion ; and I cannot still 

 avoid the suspicion tliat it is apjilicablc even to 

 such cases as that of the fura. I )r. Richardson 

 has assured me that the icebergs oft' North 

 America push before them pebbles and sand, 

 and leave the submarine rocky flats quite baie ; 

 it is hardly possible lo doubt that such ledges 

 must be polished and scored in the direction of 

 the set of the prevailing currents. Since writing 

 that Appendix, I have seen in North \\'ales 

 {I.o?nioii Phil. AAii;-. \oI. xxi. p. iSo) the 

 adjoining action of glaciers and ol II ua ting 

 icebergs.
