the summit level of the Ohio canal, and about one thousand one

Mr. Dana read a communication on the occurrence of magne- 

 sia and phosphoric acid in recent corals, as discovered by Mr. B.

Prof Hitchcock remarked on the abstract of a paper by Dr. 

 Webber, of New Hampshire, read on Thursday morning, and 

 which he had seen in the National Intelligencer, on the formation 

 of the terraced banks of Connecticut river, which was identical 

 with the theory proposed by himself in his final reports of 1830 

 and 1841 on the geology of Massachusetts. He did not doubt 

 the originality of the view in question with Dr. W., but as no 

 notice had been taken by any writer he had seen of the views in 

 his final reports, he thought justice to himself required the men- 

 tion of the fact.

 New Haven, on the last Wednesday of April, 1845.
