At the bottom of the front of the wrappers for livraisons 45-47 and 48-50 stands 

 this note : La 44^ livraison, contenant les légends explicatives des planches du tome II, 

 ainsi que les planches en retard, paraîtra incessament. Similarly there is a note on 

 the wrapper for livraisons 64-65, which reads : Nota. — Les planches, accompagnées 

 des légends explicatives, paraîtront en même temps que les premières livraisons du 

 tome IV. 



Tome 4 



The first two livraisons (67 and 68, pages 1-32) of this volume, were in one wrapper, 

 dated 1881 : ail other wrappers are undated. De Folin, in a letter of 10 May 1887 

 to DaU, says that up to that date twelve livraisons of volume 4 (i.e. pages 1-192) 

 had appeared. Livraisons 69-78 must thcrefore hâve appearcd between 1881 and 1887, 

 and livraisons 76-78 (pages 149-192) must hâve come out after 1883 for they deal 

 with the explorations of the Travailleur and Talisman in the years 1881 to 1883. 

 The last livraison, number 81 (pages 225-240) vas received by DaÙ on 22 August 1887. 



From thèse notes we see that the following corrected dates of publication 

 may stand. Winckworth's dates for the first volume are correct, but for 

 the sake of completeness I am including them hère.
