These facts must be admitted, I think, to exclude any possibility 

 of doubt as to the truly fossil character of this bone. Its peculiar 

 condition could not have been produced by any artificial means at 

 present known, and most assuredly indicates that it must have been 

 long buried in the deposit from which its metallic impregnation has 

 been derived *. 



That it could not have found its way into that deposit in any 

 other mode than by original imbedding, may be fairly concluded 

 from the entire absence of the least indication of disturbance in the 



* The cogency of these inferences is of course invalidated by the proved incor- 

 rectness of the impressions on which they were founded, as stated in the preceding 

 note. How far the genuineness of the specimen is supported or contravened by 

 other evidence, is a question on which there is at present so great a diversity of 

 opinion among experienced Palaeontologists, that I think it better to abstain from 

 any judgment in regard to it. June 15, W. B. C.
