DEPTHS AND DEPOSITS OF THE WEDDELL SEA. 
789 
Endurance results have nothing fresh to bring forward. Much that is new has, 
indeed, been found in recent years and been published, mainly in foreign periodicals. 
Such are, for instance, the finding by the Swedish Expedition of a rise between 
Joinville Island and the Powell Group, and the extremely important line of soundings 
made by the Deutschland between the South Orkneys and the South Sandwich 
Group. The latter show not a simple rise, but a series of alternate rises and deeps 
trending E. — W. and perhaps linking these two island groups. Reference may also 
be . made to a rock reported by a whaler in 1916 as lying in latitude 58° 31' S., 
longitude 41° 48 ' W. Much more evidence, however, is certainly required before it 
can be decided whether the necessary link between the geologically similar regions 
of Graham Land and Patagonia connects all the island groups forming the so-called 
Southern Antilles, or passes somewhat more to the west, as Professor Gregory would 
have it.

Sand and pebbles. 
A dredging made in this position brought up a 
mass of sponges. The bottom deposit was 
sandy, with many pebbles (the largest 2 inches 
across) of : — Grey grit, common ; purple sand- 
stone ; granite with white felspar, common ; 
basalt ; dolerite ; syenite (possibly).
