according to the illuftrious writer, with references to volume 
and page, and the addition of the Linnet an names. In the

the Comte de Buff on; and the laft contains the Englifh names 
ufed by Mr. Latham , in his moil comprehenfive Synopsis of 
Birds, in which may be found the fynonyms of the moft ef- 
teemed authors in this clafs of Natural Hiftory; an article im-

mention another great merit in Mr. Latham , in having indefa- 
tigably fcrutinized all the treafures of Natural Hiftory, brought 
home by our daring and inquifitive circumnavigator Captain 
Cook ; and in having added to the catalogue of the feathered 
tribe a number, which has fwelled his lift far beyond that of 
any preceding writer. The great, the pious Mr. Ray, could 
not pronounce that there were more than five hundred known 
fpecies of Birds ; M. Brijfon has enlarged the lift to above four- 
teen hundred : but our Englijh Ornithologift defcribes with exadt- 
nefs near two thoufand five hundred, and imagines that he 
may ftill find fubjedfs fufficient for a fupplemental volume ; 
which, for fome years at left, will leave little for future writers 
to add *.

and, with thofe hereafter to be mentioned in the Supplement, it is probable that the number 
may exceed 3,000.
