years ago, and in much better condition." I may say that there are 

 specimens in Paris, Brussels, and Leyden, as well as in the British 

 Museum collection, which are quite as large as those which I saw in 

 Whitehall Place. I think I may say, without any fear of contradic- 

 tion, that the Gorilla and its osteology and anatomy are far better 

 known than nine-tenths of the mammalia in existence. 



1 have already referred to the author having appropriated Geoffroy's 

 figure of the old and young Gorilla, and Fenton's photograph of the 

 Gorilla-skeleton, to illustrate his work, and, 1 may add, without a 

 word of acknowledgment of the source whence he derived them. He 

 seems to have very peculiar ideas as to the way in which figures may 

 be used to illustrate species, and also apparently to believe that the 

 figures of the same species need not be alike in some important 

 characters : thus, at p. 359, he gives two figures inscribed " Nshiego 

 mbouve arid young (^Troglochjtes calims)," in which the figure of the 

 older animal has rather small, and that of the young very large ears. 

 The figure of the adult is probably an original one ; but the figure 

 given as the young of this which he calls (I believe, erroneously) a 

 new species, is a copy of Geoifroy's figure of the photograph of the 

 common Chimpanzee {Troglodytes niger) ! and at p. 423, the two 

 figures of the " Nshiego mbouve, in his shelter," have both large 

 ears, like the young animal copied from the Chimpanzee ; and as 

 this is drawn by Mr. Wolf, they are probably drawn from that 

 animal : so that three out of the four figures of this presumed 

 species are from the Chimpanzee. 



M. DuChaillu gives three figures of the ' Kooloo kamba,' — the entire 

 animal at p. 270, at p. 360 the head, and at p. 361 the ear and part 

 of the head : the ears of the first two figures are very large in com- 

 parison with the other parts, while the detail figure of the ear at 

 ]). 361 is much smaller ; and the form and expression of the faces of 

 the figures at pp. 270 and 360 are very different from each other. 



The figure of the young 'Nshiego mbouve' given at p. 232 (and 

 we must recollect that this animal is regarded as a new and most 

 distinct species, and named Troglodytes calvus, as distinct from the 

 Cliimpanzee or Troglodytes niger') is a facsimile copy of the figure 

 given by M. GeofFroy in the 10th volume of the 'Archives du 

 Museum,' tab. 7. f. 4, as a representation from life of the young 

 C'himpanzee in the Jardin des Plantes at Paris ! And the figure of 

 the presumed new species, on the plate at p. 359, which, as I have 

 before observed, is so unlike the figure of the older animal on the 

 same plate, is a copy of the same figure of Geoffroy's, but reversed 

 in the copying. 



I examined with care all the specimens of the apes in the collec- 

 tion at White Hall Place, and could only make out two — the Gorilla 

 and the Chimpanzee : they are in different states of goodness, or, 

 rather, badness ; and one had lost the skin and hair of the scalp ; and 

 the above account of the figures of these jjresumcd species renders 

 them very doubtful. 



But the most remarkable instance is at p. 454, where the author, 

 describing an Anoinalurus, says, " On examination, to my joy I found
