conjectures, that he has found the mineralized remains of a pelican less 

 than pelicanus onocratutus, and larger than P. car bo ; of one of the large 

 curlews, with naked necks, disposed by Gmelin under the genus Tantalus; 

 of a woodcock, a starling, and a sea-lark (alouette de mer). 



Judging from the form and proportions of a bone which I have in the 

 marly schist of CEningen, eight inches in length, I suppose it to have 

 been the tibia of some water-fowl. Its extremities are very much in-

 stone ; so that no characteristic marks can be observed. 



On the back of the stone, and in different parts where it has been shi- 

 vered, the seeming remains of feathers are observable. Another spe- 

 cimen, a slender bone seven inches in length, so deeply imbedded in the 

 hard lime-stone of Stunsfield, in Oxfordshire, as not to allow either of its 

 extremities to be examined, is, I have very little doubt, also either the 

 tibia or tarsal bone of some bird.

HAVING now to commence the examination of the fossil remains of

 the manner in which this part of my task is accomplished. I fear that 

 you will, at first, experience feelings of disappointment, on my avowing 

 to you, that the following pages will almost entirely be employed in
