226 General Notes. [^ 



Polioptila coerulea. — On April 25, 1906, I observed a female Blue-gray 

 Gnatcatcher at Canandaigua. It was occupied in catching insects that 

 were about the blossoms of a maple tree on the edge of a swampy woods. 

 After some time in the upper branches it came down to about eye level 

 and worked along the border of the woods. This gave me an excellent 

 opportunity to observe it well. It moved on gradually in a northerly 

 direction as if migrating, but apparently was not with a flock of migrants. 

 There is one other record for Ontario County, — "Canandaigua, June 3, 

 1886." 



Hylocichla guttata pallasii. — Two Hermit Thrushes in song June 2 and 

 two others June 3, 1906, in the vicinity of West River were recorded by 

 Mr. Antes and me. It would seem that this bird is probably a not rare 

 summer resident in Yates County. "Nest found in Yates Co., May 29, 

 1898." — Maurice C. Blake, Hanover, N. H. 



Notes on the Ornithological Works of John James Audubon. — In ' The 

 Auk' for July, 1906, pp. 298-312, Mr. Witmer Stone has given a 'Bibli- 

 ography and Nomenclator of the Ornithological Works of John James 

 Audubon,' and it seems to me desirable to publish some additional notes, 

 which, although apparently well known to some persons, seem to have 

 escaped the press. 



About ten years ago Mr. Everett W. Ricker of Boston, who has a con- 

 siderable knowledge of ornithological books, showed me what he con- 

 sidered a complete set of Audubon's 'Ornithological Biography' which 

 he had picked up from time to time. This set consisted of the original 

 five volumes, Edinburgh edition, two Philadelphia editions of Volume I, 

 and a Boston edition of Volume II. With one exception they were in 

 the original bindings. I have obtained from him the Edinburgh edition 

 and he has kindly loaned me the other volumes. 



From comparison of various pages, printers' signatures, and typography, 

 it is evident that both Philadelphia editions of Volume I are from the same 

 press, and doubtless struck off at the same time. It being reasonable to 

 suppose that in those days, before electrotyping was practiced, the type 

 would not remain set any length of time. These sheets were then bound 

 with slightly different title pages and imprints as follows.

In his Bibliography, ' Birds of the Colorado Valley,' Coues, after quot- 

 ing the Edinburgh edition, says: "This same 1st vol. (other copies) is 

 said to also bear the imprint, 'Philadelphia, E. L. Carey and A. Hart 

 MDCCCXXXII,' and to be often missing"; and Leverett M. Loomis in 

 'The Auk,' VIII, April, 1891, page 230, refers to "the Edinburgh edition 

 with the Philadelphia title page, (Philadelphia, E. L. Carey and A. Hart,
