MEMORANDUM. 



SINCE the text was written, among many services 

 rendered by Mr. Edward Blyth, whose merits as a 

 naturalist are well known, the author has to thank 

 him for an interesting notice of horse-teeth, found 

 at the Big Bone Lick, the well known place where 

 the remains of Mastodon abound, which proves the 

 existence of Equidte in North America during a 

 former Zoology; and, in that particular, invalidates 

 the remarks in the text concerning their pristine 

 absence.
