CORRESPONDENCE 
LACEPEDE’S TABLEAUX. .. . DES MAMMIFERES ET DES OISEAUX ; 1799 
Lactrrpr’s ‘‘ Mémoire sur une nouvelle table méthodique des animaux 4 mamelles” 
was read before the Institute on 21 Prairial an 7 [9 June 1799]. It was published in the 
Mémoires de l'Institut, vol. iii., in 1801. Louis Agassiz quotes the table as Mém. de 
V'Instit., iii., 1797, an obviously incorrect date ; but many others have quoted it as 1799 
without giving any evidence as to the accuracy of the quotation. As great importance 
attaches to the proper date of this paper, it became necessary for me to investigate the 
matter carefully, but I could not discover any definite statement except that of Engel- 
mann, who in his Bibl. Hist. Nat. 1846, p. 376, refers to it as “‘in-4. Paris. am vii. 
(1799). Plassan. (38 pag.).” Up to the present, however, I have completely failed to 
find this 4to tract ; it cannot be a separate of the Mém. de I’Inst. paper because that was 
printed by Baudouin, and Engelmann gives Plassan as the printer of the tract ; besides 
the pages of the Institute paper are 32 against 38 of the tract referred to by Engelmann. 
But I have found, quite by accident, in Didot’s issue of Buffon’s Hist. Nat., 18mo Paris, 
76 vols., 1799-1806, in the xiv. vol. of Quadrupedes, this interesting tableau, and it is 
dated 1799, and it was printed by Plassan. The title of the two papers (for the birds 
are included) are as follows :—‘‘ Tableau des divisions, sous-divisions, ordres et genres 
des Mammiferes, Par le C™ Lacepéde ; Avec ]’indication de toutes les espéces décrites par 
Buffon, et leur distribution dans chacun des genres, par F. M. Daudin ” (pp. 143-196). 
‘‘ Tableau des sous-classes, divisions, sous-divisions, ordres et genres des Oiseaux, 
Par le Ce" Lacepéde ; Avec l’indication de toutes les especes décrites par Buffon, et leur 
distribution dans chacun des genres, par F. M. Daudin” (pp. 197-346). Both of these 
are referred to as one tract, ‘“‘in-18. Paris, 1802. Plassan,” by Engelmann, Bibl. 
Hist. Nat. 1846, p. 322. 
It will be noted first—That the Genera only are by Lacépede ; and secondly—that aii 
the species are by F. M. Daudin. 
As the period 1798-1801 is a critical one for nomenclature, I need do no more than 
point out the interest of this recovery ; but my friend Oldfield Thomas hopes to prepare 
an analysis of the Mammalia. Ornithologists will find many interesting points to con- 
sider in nomenclature when comparing the above paper with Daudin’s * Traité 
Elémentaire,” which it undoubtedly precedes.

Mr R. Quick writes from the Horniman Museum, that an examination of Mr Harrison’s 
collection of flints from the Plateau gravels of Kent has convinced him that these are 
truly primitive implements. He thus agrees with Sir Joseph Pretwich, and considers 
that Mr Cunnington’s reasoning in our last number (pp. 327-333) is not cogent. 
ERRATUM.—Page 321, line 25. or ‘Siberian’ read ‘ Silurian.’
