WILLIAM COOPER 



but, with his usual caution, and for fear of 

 making another synonym, he let it remain so, 

 until Bonaparte confirmed it as being really 

 new. 



Mr. Cooper also gave the use of his speci- 

 mens and notes to Audubon and Nuttall, the 

 latter dedicating to him the " Mtiscicapa Coop- 

 erz" which, however, had been named M. 

 borealis a little earlier. Mr. Nuttall also fre- 

 quently quotes Mr. Cooper's authority as to 

 other species, which, like this, were first ob- 

 tained by him. 4 



It must be remembered that scientific work 

 was, at that time, printed in America only at 

 private expense, excepting such additions to 

 popular works on travels, or finely illustrated 

 books on birds, etc., as were expected to re- 



4 As an instance, it may be observed that Nuttall quotes 

 Cooper as saying that " Falco Coofieri (described in imma- 

 ture plumage in 1828) bears the same analogy when adult to 

 the adult of Falco fusctts as the young of that species does to 

 the young of Cooperi." Audubon, however, named the adult 

 bird Falco Stanleii, thus subjecting himself to the charge of 

 a lack of scientific accuracy, as he was doubtless acquainted 

 with Bonaparte's work, and indeed felt compelled to acknowl- 

 edge, in 1839, the identity of the species.
