^ ANIMALS IN BIENAGERIES. 



habits, he must, in almost every instance, have recourse 

 to others : he is absolutely shut out from all other 

 sources of information ; and he is, from necessity, often 

 obliged to avail himself of resources used by others on 

 similar occasions. Nevertheless, if he judiciously select 

 from the best authorities, and reject those which he con- 

 siders questionable, he at least may do some good, by 

 discountenancing what has not the appearance of truth, 

 and thus purifying animal biography from some of its 

 numerous errors. Besides, the stream of discovery is 

 constantly bringing within our reach morsels of truth and 

 of veracious anecdote, which require adding to the general 

 stock of know^ledge ; and these will sometimes so alter 

 the former history of an animal *, as to give it an en- 

 tirely new character. 



The scientific ornithologist will, we hope^ be satisfied 

 by the description of more than two hundred new or 

 little known birds contained in the Third Part ; being 

 that portion of our ornithological labours which want 

 of space obliged us to omit in a former volume, and of 

 v^diich, in fact, it should be viewed as an Appendix. 



Such a considerable number of quadrupeds have been, 

 at different times, imported into England, and exhibited 

 in menageries, that it became absolutely necessary to 

 make a selection. We have, therefore, omitted the ele- 

 phant, the rhinoceros, the oran-outang, and a few 

 others of the best known ; since their histories have been 

 so often repeated, that they must be in the hands of 

 almost every one. This has given us more space for the 

 introduction of others, whose natural history has been 

 illustrated by the observations of recent travellers.
