horse on which most of the painters mount him. Professor Owen 

 informs me that Roland Savery's picture containing the Dodo, in the 

 Berhn collection, hears the date of 1626 ; and that the colovir of the 

 Dodo in the Duke of Northumberland's picture resembles that of the 

 portrait of the bird, of life size, by the same painter, now at Oxford. 

 L'Estranjie describes the hue of the back of the livin": Dodo which 

 he saw exhibited in London "about 1638," as of " dunn or deare 

 colour."
