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

 Thuffday the 31ft of May laft, before the Royal 

 Society, on account of the happy opportunity 

 you were fo kind to give ine of dilTeding the 

 African Bearded Vulture, which you Ihewed 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 aélions, not only 

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

 other bird whatfoever, will be found in the a- 

 bove mentioned le6lure, in the tranfadlions of 

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

 deed fome others mentioned in my ledure, were 

 never obferved before, it rnay not be improper 

 to add a little account of them to your Pliftory 

 of the Vulture, if you think proper -, for they 

 are about the fame fize, and in the fame fituation 

 with thofe of the Haliîetos, which gave occafion 

 to the ledlure ; and both birds are nearly related 

 to each other, being of the fame genus. 



" This mufcle on each fide is about two 

 inches long, arifmg flefny by three diglti from the 



fécond.
