sous-divisions, ordres et genres des mammiféres par de C™ Lacepéde,” 
[ete.] “A Paris, chez Plassan [etc.] L’an vii de la République,” pages 
1-18; followed by “Tableau des sous-classes, divisions, sous-divisions, 
ordres et genres des oiseaux” [no title-page or date], pages 1-20, and 
“de Vimprimerie de Plassan.” 
The whole is bound in the original boards, and is uncut in two 
places; is obviously a complete and perfect book ; contains the 38 pp. 
tract referred to by Engelmann on p. 376; and was reviewed in detail 
in the Journ. général Litt. France, iii. 1800, Nivése An viii. (December 
21, 1799, to January 19, 1800), p. 7. Having, therefore, found this 
missing book, we are now in a position to speak definitely as to the 
date of Lacepéde’s generic and specific names. They first appeared 
in print quite towards the end of 1799, in the newly found tract. 
They were quoted by Daudin in his “ Traité Orn.” 1800 (Richmond, 
Auk, SNP. B2() they were printed in MZém. de I’ Inst. iii. 1801, reset 
and repaged, and with the “errata” which appeared in p. 56 of the 
“ Discours” corrected; they also appeared, with additions by Daudin, 
in vol. xiv. of the Quadrupedes of Didot’s Buffon in October 1802; from 
which volume separates were issued in the same year, of which one 
copy, and that of birds, is known. It is further to be noted, as a 
correction of my previous note, that of the specific names Lacepéde 
supplied one each to the mammals, as seen in the original tract and in 
the Mém. de ’'Inst., while the whole of the other specific names are 
Daudin’s, and their date must of course be a matter of separate 
individual inquiry. 
Professor Newton, who has followed the whole inquiry in the 
kindest and closest manner, has carefully examined the 1799 tract 
and says: “My impression is that the two ‘Tableaux’ (Mammals and 
Birds), each of which has its own pagination, distinct from that of the 
‘Discours, must have been printed before the ‘Discours’ were— 
and the Birds indeed so long before as An vi., on the 6 Fructidor, 
of which year the table was shown to and a memoir upon it read 
before the Institute, as he himself [Lacepéde] stated on the 21 
Prairial of the following year, when he presented the Mammal scheme. 
You will observe that the ‘Tableau’ of Birds in your copy has no 
separate title-page, and it looks as if that was printed off in An vim 
the ‘Tableau’ of Mammals not being printed till the following year— 
in which year also the little Buffon, according to its original title- 
page (‘chez Saugrain,’ etc.), was printed, i.e. 1799, while in my view 
the original ‘Tableau’ of Birds belongs to An vi. te 1798! 
Whether publication in the strictest sense of the word can be claimed 
successfully for that date is more than I should like to say; but there 
ought, I think, to be no doubt that his genera both of Mammals and 
Birds were published in An vii. (1799).” 
In a further letter Professor Newton points out, that while in the 
Mém. de V Inst. the errata that appeared on p. 56 of the “ Discours”
