brought home from С Fletcher. Besides, already macroscopi- 

 cally, red porphyries, mostly poor in quartz, are very prominent, 

 and further bind together these rocks with those just named. 



Microscopically we can distinguish several varieties of por- 

 phyries among the pebbles, with often a very dense, aphanitic 

 though not really micro-felsitic ground-mass. Among the phen- 

 ocrysts we very often find chlorite accompanied by apatite and 

 ore, and in a distinct crystal form that seems to derive from biotite, 

 even if occasionally hornblende should suggest itself. The re- 

 semblance to the acid extrusive rocks of С Fletcher and the 

 conglomerate pebbles of C. Brown is striking. Then 1 came 

 across a fine granophyre granite. I have also examined a red, 

 rather porphyritic granite. It is hard to determine where this 

 rock should be classed. The quartz is fairly hard pressed and 

 shows no crystallic shape, but is sometimes intergrown with 

 plagioclase in a way that reminds one of a very coarse micro- 

 pegmatite structure. The plagioclase itself usually shows idio- 

 morphic outlines, and microcline is absent, through which the 

 rock differs from the red granites, already described, which 

 crop out in the district and with which in other respects a 

 certain resemblance is to be seen. 



The rocks in the valley between Liverpool Land 

 and Jameson Land (Ryder's Л^аИеу). These rocks, just de- 

 scribed, were met with a little way up the slope towards the 

 higher gneiss-area. Down in the valley itself the rocky foun- 

 dation is not often exposed, but where it is to be seen, for 

 instance near Vargudden, it consists, just as it does on the 

 Fame Islands, for the most part of a coarse ruddy conglomerate 

 which differs from the one just described in its looser con- 

 sistency, and in that the pebbles and grains are mostly com- 

 posed of quartz. Besides these, grains of granitic rock occurred, 

 while in the specimen examined by me only a few small pebbles 

 of micro-granite were seen, though their type could not easily 

 be determined. The matrix chiefly consists of calcareous mass.
