Dodo (from the painting by Goeimare, 1627, in Sion House).] “In this picture, which seems to have been intended as a record of rarities, the foreground represents a sea-shore from which the tide has retired, leaving empty shells of the following genera:—_Nautilus_, _Pteroceras_, _Strombus_, _Triton_, _Pyrula_, _Cassis_, _Cypræa_, _Conus_, _Mitra_, _Turbo_, _Nerita_, _Mytilus_, _Ostrea_, &c. Behind, on elevated ground, are two Ostriches; and below, to the right of the spectator, the Dodo is represented as in the act of picking up something from the strand” (fig. 5). “The head and body of the bird, covering an area as large as the palm of a man’s hand, are seen; but the legs are hidden. The painter of the Dodo, in _my_ picture” (Pl. I. fig. 2), “has given the only complete foreshortened back view of the bird known to me. In the Duke’s picture the head and body are presented to the spectator on a larger scale; and I have nowhere seen the hood or ridge at the base of the bill, from which the bird obtained the name of _Cygnus cucullatus_, so clearly represented. Near the Dodo are a Smew and other aquatic birds, and further off Hoopoes and Terns. In the distance is the ocean, with a sea-monster awaiting the attack of Perseus, who descends on a winged steed to the rescue of Andromeda chained to a rock. Those who have had occasion to describe and figure new species of Testacea, know how difficult it is to find a draughtsman who can give a correct design of the shell to be represented. Unless the artist, like Mr. G. B. Sowerby, jun., is aware of the internal structure of the shell, and acquainted with its organization, a lamentable failure is generally the result. In the picture before us, with one exception—and even in that the specimen may have been distorted—so accurate was the eye of the painter, that if he had been aware of the organization of each shell—knowledge which he probably had not—he could not have represented the objects more correctly. The _Nautili_[14], _Strombus gigas_, _Triton_, and _Pyrula_ are painted with great breadth and power, and all are drawn and coloured with wonderful truth; indeed a conchologist may name every species. One of the _Nautili_ is partially uncoated, to show the nacre, and the other dissected, to display the concamerations. None of the shells have the epidermis, and all are of the natural size. The artificial condition of these subjects, and especially of the _Nautili_, is, it must be allowed, rather out of place in an assemblage of testaceans left on the sands by the retired tide, unless we are to suppose that the sea-nymphs had been amusing themselves by polishing the specimens and displaying the internal structure of one of them; but this very treatment shows that the designs were accurately made from real objects then considered as rarities. With the exception of the Dodo, none of the natural objects represented
