1 have not yet received the bones, but they will be in 

 New York within a few days at nr)y disposal. I put the 

 question respecting tne matters covering the floor of the 

 cave, in the fullest form, to Mr. Robe, and particularly drew 

 his attention to the probable occurrence of rolled stones, 

 mu'i. &c. supported or invested, together with the bones, by 

 a layer of stalagmite — no mention is made in his letter of 

 such appearances. 



I intend to offer you a paper on the Geography and Geolo- 

 gy of the Lake of the Woods, but I cannot now say when it 

 will be ready, as that partly depends on a map at present 

 unfinished. The matter would be novel and interesting, 

 including the calcareous formation north of the valley of 

 the St. Lawrence,

Mr. Jeffrey, the principal conductor of the Edinburgh 

 Review, has obtained the opinion of Professor Buckland. the 

 celebrated author of the Rehgu ce Diluviance, on the above 

 work of Professor Eaton. In a letter to the Hon. S. Van 

 Rensselaer, Mr. Jeffrey has given the result. Mr. Buckland 

 says, that the " author seems both to understand his auhject, and 

 to have done his work carefully '''' The work contains oideed 

 abundant evidence of extensive and patient examuialion. 

 This point will not be aifected by the adoption or rejection of 

 Mr. Eaton's peculiar views by our geologists. In some parts 

 there is an evident improvement upon some of his previous 

 publications on the geology of our country. Thus at page 

 31, and page 62, and onwards, we find introduced '" Primi- 

 tive Argillite," a rock so clearly separated, and so easily dis- 

 tinguished in our country from "Transition Asgilliie,'' though 

 both are united under the latter name by Bakewell and some 

 others. 



Mr. Buckland makes some objection to the .sfyZe, and com- 

 plains of Mr. Eaton for "affecting some needless novelties 

 in technical language " However true this charge may be, 

 the censure is feeble when compared with the commendation 

 contained in the previous quotation. In our country, the 

 work has been censured for this fault, and more particularly
