206 CHANGE OF PLUMAGE IN HEN-BIRDS. 



Professor Jameson, in his lectures, gives a well 

 attested instance from the writings of Tiedemann, of 

 a domestic cock which lived twenty-five years. 



The computed age of a fowl, correspondent to 

 that of man, whose days are said to be three score 

 years and ten, I would average at 15 years, viz. as 

 about 1 to 5, or 15 to 72. 



Most fowls would probably die under that age, 

 by accident or disease ; but some few may live to the 

 extraordinary age of 25, as old Parr lived to 152, and 

 Henry Jenkins (both of whom died in the county of 

 York) to 169 years of age.
