Note 20 — Chapter XXVII · EASTERN VISIT AND EXPLORATIONS IN THE NORTH ATLANTIC

It was possibly during his visit to this city that an experiment was made in bringing out some of his plates by lithography. Two copies of a large plate, possibly the only one produced, lithographed without colors, were shown to me by Mr. Goodspeed, of Boston, in the summer of 1910; these represented the "Rallus crepitans—Marsh Hen," and bore the following legends: "By John J. Audubon, F.R.S., &c., &c.," and "Drawn & Printed by Childs & Inman, Philadelphia, 1832." Three birds are here figured in place of the two which appear in the plate of this species which Havell later engraved, and in composition the two publications are quite distinct.
