fell on the 26th.) To this Audubon must have replied, but his letter is 

 missing from the Linnaean collection. To that lost letter Swainson's 

 letter of "2d October 1830" undoubtedly is an answer. The letters are 

 published in the following Journals : 

 1830, Aug. 22 (Manchester). Audubon's letter proposing cooperation, 



etc. (Synopsis in Proc. Linn. Soc, London, May 22, 1900, p. 26; 



republished in Osprey, IV, p. 24 ) 

 1830, Aug. 26. Swainson's letter (undated) published in Auk, XXII, pp. 



32-34- 

 1830, Aug. 29. Audubon's letter in reply to last : apparently lost. 

 1830, Oct. 2. Swainson's letter in answer to last, published in Auk, XV, 



1898, pp. 11-13 ! republished in Osprey, IV, p. 171, V, pp. S, 9. 

 Let us hope that the editor of 'The Auk ' will procure a cop}' of Audu- 

 bon's letter of Aug. 22 and publish it. — Theo. Gill, Washington, D. C.
