OWEVER certain I have prefumed to be in the Synopjts, 

 that the Henharrier and Ringtail were different fpecieSj I have 

 lately had occafion to fufpend that opinion, for the reafons below 

 mentioned, of which the candid reader is left to judge for him- 

 felf, whether there may be foundation or not for retracing it. 



At the time of our fuppofing that the two birds above men- 

 tioned were of different fpecies, we departed from the opinion of 

 that faithful and obfervant naturalift, , M, Brijfon, who joins the 

 two without hefitation, as well as the authority o^ Ray and Wil~ 

 Jughby, with fome others of leffcr note, who likewife efteemed 

 them as one and the fame ; but we were induced fo to do from 

 the teftimony of Mr. Pennant having found a Ringtail of the inale 

 fex, feconded by a fimilar circumftance falling under our own ob- 

 fervation, which naturally led us to fufpedl the pofTibility of the 

 " above-mentioned writers having been miftaken.

 two birds together ; when we fliall find, that, -
