LIS tf OF PLATES. 
OO DO 
Piate I.— Frontispiece.—Fac-simile of Roland Savery’s figure of the Dopo in his picture of the Fall of Adam, in 
the Royal Gallery at Berlin. 
Prats I. p. 9.—Fac-simile of Plate 2 of the French edition of Van Neck’s Voyage, fol. Amsterdam, 1601. This 
plate is copied by De Bry, and other editors of Van Neck. The Dopo, at Fig. 2, is also introduced by 
De Bry into the ornamental title-page of his India Orientalis, Pars V. 
Prats III. p. 30.—Fac-simile of Roland Savery’s picture of the Dopo in the Belvedere at Vienna. 
Prats III.* p. 46.—View of the Island of Rodriguez, looking South. 
Prate IV. p. 48.—Fac-simile of the Frontispiece of Leguat’s Voyage. 
Puate IV.* p. 50.—View of Port Mathurin, Rodriguez, looking West. 
Plates II., III., II1.*, IV., and IV.*, are examples of various applications of Avastatic Printing. Plate II. isa fac-simile of an engraving 
executed by tracing the original, line for line, with a steel pen, lithographic ink, and tracing paper. The drawing is then trans- 
ferred, by the Anastatic process, to a plate of zinc, and printed from as iv ordinary zincography or lithography. Plate IV. is 
executed in the same way as Plate IT., except that its details are copied by the eye instead of being ¢raced. Plates III., III.* 
and IV.*, are examples of a new art to which I have given the name of Papyrography, (See Atheneum, Feb. 12, 1848.) It 
consists in drawing on paper with lithographic chalk, and in transferring the drawings, so made, to a plate of zinc, by the 
Anastatie process. These drawings, when printed, bear a close resemblance to lithographs, and enable an artist or a traveller by 
merely using lithographic chalk instead of a lead pencil, to print and publish his original sketches (without redrawing or 
reversing), at any interval of time. For Plate III.* and IV.* I am indebted to E. Higgin, Esq., of Liverpool, who sent the 
drawings by post to Oxford, where they were transferred and printed by Mr. P. H. Delamotte.—H. E. S. 
PuaTE V. 
Fig. 1. Side view of the head of the Dopo, with the dried skin, from the unique specimen in the Ashmolean Museum 
at Oxford. 
Fig. 2. Side view of the head of the Dono, restored chiefly from the celebrated picture, presented by Edwards to the 
British Museum. The great development of the cere, the tubular nostril opening forwards, the form 
and abrupt termination of the horny sheaths which have disappeared in Fig. 1, the extent of the gape, 
and the caruncular folds at the base of the upper gnathotheca, on the forehead, and extending from the 
angle of the mouth, are well exhibited. 
Puate VI. 
Front, side, and back views of the leg of the Dopo, in the British Museum. These two plates were executed 
for that valuable work, the “Genera of Birds,” by Messrs. G. R. Gray, and D. W. Mitchell, who have 
obligingly allowed us the use of them.
