 been fully satiated. 



A very singular, if not unparalleled, instance of the 

 voracity of the Perch occurred to me when fishing in

 I think, conclusively, that the structure of cold-blooded 

 animals enables them to endure very severe injuries and 

 wounds without experiencing material inconvenience ; a
