 ON THE DATES OF PUBLICATION OF D'ORBIGNY'S 



"MOLL, VIV. ET FOSS," 

 "PALEONT. UNIV." and " PALEONT. ETRANGERE." 



By C. DAVIES SHERBORN. 



(Read before the Society, February 8th, 1905). 



D'Orbigny's "Moll. viv. et foss." — According to the Bull. Soc. 

 geol. France (3), iii., 1846, 805, parts i — 6 (480 pp.) appeared in 1845. 

 According to the Bib'. Francaise, parts i — -3 were recorded 16 May, 

 1846, and contained "about 15 sheets and 15 plates." Wiegmann, 

 Archill, 1847, p. 379, says : "Im vorigen Jahresbericht S. 414 ist das 

 erste Heft eines Werkes von d'Orbigny erwahnt worden; Mollusques 

 vivants et fossiles ct. Im Jahre 1845 sind auch bereits die folgenden 

 6 Hefte, mit denen der erste Band geschlossen ist, erschienen." This 

 evidence is so conflicting that we can get nothing definite, so I sug- 

 gest that the simplest way to proceed is to accept the dates given by 

 the author himself and date as follows: — 



up to p. 432* d'Orbigny quotes 1845 



576 „ „ 1846 



„ 605 „ „ 1847 



D'Orbigny's "Pal. Univ." — According to the Bull. Soc. geol. 

 France (3), iii., 1846 (the only record of the appearance of the work 

 that I can find) part i was received 16 March, 1846 (p. 381); parts 

 2 and 3, 18 May, 1846 (p. 499), while on p. 805 of the same volume 

 it is stated that two parts appeared in 1845 containing 160 pp. and 

 40 plates. Here again I think we should accept the statements of the 

 author as follows: — 



up to p. 208* d'Orbigny quotes 1845 



» 368 „ „ 1846 



392 -^ „ „ 1S47 



D'Orbigny's "Pal. Etrangere." — This I have not accessible yet. 

 It is obviously on similar lines to the above two works as some of the 

 plates bear the three titles in their head-lines, though with differing 

 plate numbers. I should adopt precisely the same plan of quotation 

 for dates as suggested for the two above named works. The only 

 record that I can find is Bull. Soc. geol. France (3), iii., 1846, 499 

 and 805 and the information there given is that part i was received 

 on the 18 May, 1846, and contained 80 pp. and 20 plates. M. Paul 

 Klincksieck, of Paris, has kindly informed me, through M. Justen 

 (Dulau and Co.), "La Pal. etrang. est un extrait de la Pal. Univ. 

 comme I'indique un Catal. de I'editeur Gide {pas de Bertrand) que 



* i.e. to the end of the sheets on which the year occurs.
