covered in the Sea^Eagle and other birds, read on 

 Thurfday the 31ft of May iaft, before the Royal 

 Society, on account of the happy opportunity 

 you were fo kind to give me of differing the 

 African Bearded Vulture, which you fliewed to 

 them at one of their meetings, in order to fearch 

 for the fame mufcles, which I found in your 

 company. 



Whatever relates to their adtions, not only 

 in the Eagle and Vulture-kinds, but alfo in every 

 other bird whatfoever, will be found in the a- 

 bove mentioned leélure, in the tranfaftions of 

 that time : but as this pair of mufcles, and in- 

 deed fome others mentioned in my ledture, were 

 never obferved before, it may not be improper 

 to add a little account of them to your Hiftory 

 of the Vulture, if you think proper ; for they 

 are about the fame fize, and in the fame fituation 

 with thofe of the Halistos, which gave occafion 

 to the leélure ; and both birds are nearly related 

 to each other, being of the fame genus. 



" This mufcle on each fide is about two 

 inches long, arifing flefhy by three digiti from the 



fécond.
