Ollivier of Pall Mall, Mr Ruxton took " a glance at the re- 

 spective claims of Great Britain and the United States to the 

 Territory in Dispute," which he has worked out historically

When we reflect that all we have stated is the work of one 

 who had but just attained his twenty-seventh year, and that 

 he has been suddenly taken from us, a victim to climate, in 

 the active prosecution of farther research, — a working-bee col-

On Ancient Sea- Margins, with Observations on the Study of 

 Terraces. By James D. Dana. 



Mr R. Chambers, in his work on " Ancient Sea Margins,''* 

 has entered upon a subject of great scientific interest. It 

 rises beyond the study of isolated deposits, or local pheno- 

 mena, and embraces facts bearing upon the geological history 

 of whole continents, indicating wide changes in the earth's 

 surface, and the latest of this general nature our globe has 

 undergone. The truth, moreover, is exhibited in characters 

 which cannot be mistaken, even by the mind unaccustomed 

 to geological evidence. It is marked in the condition of the 

 soil, and in the extent and features of the fields of our valleys ; 

 and even the higher country along the smaller streams, bears 

 evidence that the same causes have there modified the main 

 outlines of the land, and determined its variations of character.

 plain or prairie along our streams ; and knows that he often 

 may distinguish the different flats by the peculiarities of soil 

 they present.
