7000 feet beneath the crests, which consisted of white coral and pieces 

 of lava. Off the Kurile Islands the sea-bottom consisted of greyish 

 black sand, gravel, and lumps of lava. Similar sand occurred at the 

 Aleutian Isles. C. E. De R.

Remarks on a collection of worked flints, chiefly palaeolithic, from 

 Canterbury, and from the coast between Heme Bay and Reculver. It 

 is maintained that the Canterbury implements are of ruder workman- 

 ship, and probably older than those from Reculver ; and the author 

 supports this view by contrasting the geological characters of the 

 implement-bearing beds in the two localities. E. W. R.

The specimen was found in 1863 in peat at Burwell Een, and was 

 described at the time in the Antiquarian Communications to the Camb. 

 Antiq, Soc. (vol. ii. no. xiii. p. 285). Reasons are now given why the 

 celt must have been fixed in the skull at the time it was covered up by 

 peat. W. T.
