NOTE BY THE AUTHOR. For the citation of this rare document, from the only copy known to exist, I am indebted to the kindness of Mr. Ruthven Deane, who writes: "I found this Prospectus bound in the first volume of _The Ibis_ (1859). This copy was previously in possession of the late Pierre Verreaux, of Paris, France, and is now in the John Crerar Library, Chicago, Illinois." Ornithologists will be pleased to find that it immediately sets at rest numerous disputed questions concerning the plates and text of this sole, but ill-fated, attempt at the republication of the original folio of _The Birds of America_ in America. (See Bibliography, Nos. 9 and 10, and Chapter XXXVI, p. 296.) Mr. Ruthven Deane has written me that an examination of the account books kept by the Audubons during the publication of the large and small editions of _The Birds of America_ showed partial payments on the Folio by 23 subscribers; the only name among those not listed in the _Ornithological Biography_ was that of J. R. Peters, who was credited with a payment of $412.00. Mr. Deane adds: "I have a list of the subscribers to the 1840, 8vo., edition, of 1,095 names, New York, Baltimore and Boston taking 501; also a list of subscribers to the _Quadrupeds of North America_, 3 volume, 8vo., edition, of 2,004 names, New York, Boston and Charleston, South Carolina, taking 1,102." APPENDIX IV AUTHENTIC LIKENESSES OF JEAN JACQUES FOUGÈRE AUDUBON 1. _1824._—Oil portrait by himself; painted at "Beech Grove," William Garrett Johnson's plantation, West Feliciana, Louisiana; presented by Audubon to Mrs. Johnson; inherited by her daughter and granddaughter, and now in possession of Dr. D. G. Murrell, Paducah, Kentucky. Size of original, 12 by 9 inches. Reproduced in _The Auk_, vol. iii, 1886 (see Bibliography, No. 184). 2. _1826_ (?).—Oil portrait by himself (?), 18 by 32 inches, West Feliciana; presented by Audubon to Col. Edward Durrive's father, later acquired by Mr. E. Curtis, and now in the possession of Mr. Thomas P. Thompson, New Orleans. My information concerning this doubtful portrait has been derived entirely from Mr. Ruthven Deane, to whom its present owner recently wrote: "My Audubon, by himself, attracts much interest, and grows more real as time makes it familiar." 3. _1826._—Pencil sketch by himself; signed "Audubon at Green Bank _Almost_, Happy!!— Sepr 1826." Made at the home of Mr. William Rathbone, Sr., and presented to Mrs. Rathbone; now in possession of Mr. Richard R. Rathbone, Glen-y-Menai, Anglesey; for reproduction see _The Life and Adventures of John James Audubon_, edited by Robert Buchanan, and Maria R. Audubon, _Audubon and His Journals_.
