named, but he makes a curious error in regarding what is now Jessie Bay at the north- 

 western end of Laurie Island, as being confluent with the present Scotia Bay to the 

 south, so that Laurie Island appears to be divided in two by a narrow channel at its 

 western end. The French add only two new names to those of Powell and Weddell 

 already existing: Pte Chaumont and C. Valavielle, both given to prominent points on 

 the north coast of Laurie Island. Pte Chaumont, however, wrongly displaces Powell's 

 original Route Point.

THE BRITISH ADMIRALTY CHART, NO. 1238 



Although D'Urville's Atlas (in which Fig. 6 appears) was not published until 1847, 

 a much earlier chart of the South Orkneys also based on Vincendon Dumoulin's work 

 was published in 1838 in Annales Maritimes et Coloniales. The original of this chart 

 accompanied one of D'Urville's first despatches to France on the early work of the 

 expedition dated "25th May 1838, at sea".^ This chart must be regarded as being of a 

 preliminary nature, a "croquis provisoire", and as such it differs in certain important
