FIG. 1 (Map B). From a photograph by A. B. ARMITAGE (A. 16, i-plate), Dec. 10, 

 1903 ; looking westward to the Royal Society Range from the western 

 shores of M'Murdo Sound. (See Plate XCIV., giving a near view of the 

 glacier-face which can be seen in the mid-distance of this figure.) 



FIG. 2 (Map B). From a photograph by A. B. ARMITAGE (A. 15, f-plate), Dec. 9, 

 1903; looking westward to the Royal Society Range from the western 

 shores of M'Murdo Sound. 



Ice-slabs are to be found occupying all the valleys amongst the foot-hills on 

 the eastern side of the Royal Society Range. They are the remnants of glaciers 

 which once drained the main snow valley, and continued their course to the coast. 

 They are now cut off from their original source and terminate in ice-cliffs some 

 miles from the actual coast, leaving about them, as they gradually dwindle, a valley 

 strewn with morainic rock-debris and boulders.
