Rem. This is evidently a natural produdion ; a

Rem. It is a bill or beak by no means unknown in 

 the United States, being common to all ra- 

 pacious birds, fuch as the eagle, hawk, vul- 

 ture, &c. their upper mandible, like that of 

 the prefent fubjed:, having a cultrated point, 

 the diflinguifliing mark of birds belonging to 

 that clafs. From the fize and general form of 

 this figure, it appears to have been defigned 

 to reprefent the beak of an eagle.

 lour, tolerably well poliflied, and not unlike 

 eborty in appearance, but much lefs pon-

Rem. The former part of the writer's conjedlure as 

 to the fubftance of this article is right, as far 

 as it goes : it is not the ordinary coal, how- 

 ever, but what is ufually termed Cannel coal 

 \ampelites'\ as the bare infpedion of the fub- 

 jed will difcover.* Col. Sargent fuppofes, 

 that the fmall perforations in the rim were 

 defigned to fecure it upon a large axis. But, 

 if a rotatory motion was intended to be given 

 to it, an angular perforation in the centre, in- 

 rtead of the circular one there, would have 

 far mere efficiently anfwered that purpofe. 

 It is worthy of remark here, that in the Tranf-

* Were farther proof neceffary, I might refer to the fpecimen of Cannel 

 coal brought from Cincinnati and by me prefented to the Society.
