" Ce sont incontestablement de tous les eties dont ce livre nous revele rancienne 

 existence, les plus extraordinaires, et ceux qui, si on les voyait vivans, paroitroient les 

 plus elrangers a toute la nature actuelle." — Cuvier, Ossemens Fossiles, pt. 2, v. 379. 



The upper figure represents Pterodactylus crassirostris, the lower, Pter. brevirosuis 



There existed at a certain but unknown era of the world, animals 

 so different from any with which we are acquainted in a living state, 

 that we seem almost lost in our attempts to understand their structure-'
