LETTER XI. 



To the same. 



SELBORNE, September gt/i, 1767. 

 T will not be without impatience that I shall 

 wait for your thoughts with regard to the 

 falco; as to its weight, breadth, &c., I wish 

 I had set them down at the time; but, to 

 the best of my remembrance, it weighed two 

 pounds and eight ounces, and measured, 

 from wing to wing, thirty-eight inches. Its 

 cere and feet were yellow, and the circle of its eyelids a bright 

 yellow. As it had been killed some days, and the eyes were 

 sunk, I could make no good observation on the colour of the 

 pupils and the irides. 1 



1 It was a peregrine falcon, falco fcregrinus. ED.
