only of the text, was also issued. In the first volume there 

 were twenty-three plates, each illustrative of a new species. 

 Owen described the Notornis, then supposed to be extinct, 

 though living specimens have since been taken ; and Dalmatoff 

 published interesting notes on the European bison. Huxley's 

 first contribution — On the Anatomy of Trigonia — presented 

 by Professor E. Forbes on his behalf-^ was printed in the 

 following year, and, strange to say, the author is entered as 

 " G. Huxley." The Secretary described a hybrid chick between 

 the common and the Victoria crowned pigeon, hatched in the 

 Gardens ; and a hybrid bull belonging to the President, that had 

 been deposited for some time in the Gardens. There was no 

 history of the animal, beyond the fact that it had been imported 

 from India about 1845. It appeared to be the produce of a yak 

 sire and a zebu dam, and the influence of yak blood was visible 

 in the tail and the long hair on the limbs, though the pendent 

 hair was absent from the sides. Notable papers in the last 

 year of the decade were those by Mantell, on Notornis, and 

 Westwood on the tsetse fly, which he described and named. 



Two volumes of Transactions were published: the second, 

 completed in 1841, contained twenty-six memoirs. Those of 

 Owen treated of the osteology of the orang, the anatomy of the 

 Nubian giraffe and the apteryx; the striped ant-eater and 

 the sable antelope were described respectively by Waterhouse 

 and Harris, and there Avere also contributions from Bell, 

 Westwood, and Yarrell. The third volume appeared in 1849 : it 

 contained eighteen memoirs, of which the most important were 

 those by Owen on Dinornis, the dodo, and the gorilla, or, as it 

 was then called, the great African chimpanzee ; and the papers 

 on the apteryx and the marsupials were continued. In this 

 volume is a figure of the femur from New Zealand, on which 

 Owen founded the genus Megalornis, for so at first he desig- 

 nated the great wingless bird, to which the thigh bone, resembling 

 that of an ostrich, belonged. This name, however, was pre- 

 occupied, and it was accordingly changed to Dinornis. 



The returns of the number of animals in the Menagerie are 

 incomplete, those for 1846, 1847, and 1848 being the only ones 



* Huxley did not become a Fellow till 1860, and of course till then could not 

 present a paper.
