Two volumes of text were published in 1825 and 1833 respectively; the first, after readjustment to fit the "quinarian doctrine," to which Selby was a temporary convert (see [Vol. II, p. 94]), was issued in a second edition at London, in 1841; the second volume bore the imprint of Lizars, who soon after began to work for Audubon.

Selby's plates were for the most part rather crudely drawn, etched and colored, and could be commended only as the work of amateurs who strove for accuracy.

[342] Among the sixty or more persons to whom Audubon carried written credentials at this time were the following: the Duke of Northumberland, Robert Peel, Sir Humphry Davy, Sir J. D. Aukland, Albert Gallatin, the American Minister, Sir Thomas Lawrence, David Wilkie, Dr. Buckland, Dr. Holland, Dr. Roget, Dr. Wollaston, William Swainson, Sir William Herschel, and his son, afterwards Sir John Herschel, John George Children, R. W. Hay, N. A. Vigors, Captain Cook, John Murray and Robert Bakewell (see [Vol. II, p. 134]).

[343] Probably the same that is referred to in his journals as "Mr. Hays, the antiquarian."

[344] J. G. Children (1777-1852) was early interested in chemistry, and at Tunbridge built a good laboratory, in which Humphry Davy conducted many of his early experiments, and while there was seriously injured in October, 1812. In 1824 Children discovered a method of extracting silver without the use of mercury. When Mr. Children, Senior, became insolvent through the failure of his bank, his son obtained a position at the British Museum; in 1816 he was librarian in the Department of Antiquities, but in 1823 he was transferred to a post in zoölogy which was eagerly sought by William Swainson; he was secretary of the Royal Society in 1826-27, and again in 1835-37. He resigned his position at the Museum in 1840, when Swainson was again an unsuccessful candidate, and was succeeded by J. E. Gray (see [Note, Vol. I, p. 353]). Children was not a productive zoölogist, but has been described as a lovable soul, who was never soured by illness or other misfortunes, and who was as zealous in his friendships as in science. See "A. A." (Anna Atkins), Memoir of J. G. Children, Esq. ([Bibl. No. 175]).

[345] In the account which follows, as well as in numerous instances in [Chapter XXXII], I am most indebted to George Alfred Williams, who in "Robert Havell, Junior, Engraver of Audubon's The Birds of America," ([Bibl. No. 232]) (Print-Collectors Quarterly, vol. vi, no. 3, pp. 225-259, Boston, 1916), has given the only satisfactory account of the Havell family and the best analysis of the work of the great engraver.

[346] Mr. Charles E. Goodspeed, who recently sent me two of the original plates of the Prothonotary Warbler, one bearing the legend "Engraved by W. H. Lizars Edinr," and the other, "Engraved, Printed & Coloured, by R. Havell Junr," called attention to the identity of the two engravings. That these two impressions are absolutely identical in aquatint and line is proved by applying a magnifying glass to any part of their surfaces, and by counting and comparing the lines or dots within any selected area whatsoever; in short, they differ only in their legends, and in the coloring which was applied by different hands. That such methods should have been adopted for excluding Lizars' name is certainly surprising. In the first or Edinburgh impression of Lizars' original plate, the artist's legend reads: "Drawn by J. J. Audubon M. W. S.," and names of bird and plant appear at the bottom of the plate in three lines: "PROTHONOTARY WARBLER. Dacnis protonotarius. Plant Vulgo Cane Vine." In the London edition the corresponding designations are: "Drawn from nature by J. J. Audubon F, R, S. F, L, S.," and PROTHONOTARY WARBLER. Sylvia Protonotarius. Lath, Male. 1. Female, 2. Cane Vine.," in four lines.
