(into which apparently the granite is intrusive), a tcrystalline lime- 

 stone, the second striking 7 S. of S.S.E., dipping 10 on the western 

 side, the third striking 10 N. of E., dipping 85 southerly, but with 

 many contortions. On the south side are fgranites, of which, accord- 

 ing to Mr. Conway, the mountains rising on this side of the lower part 

 of the glacier consist. The moraine on the right hank furnished an 

 ordinary limestone, a black argillite, and a crystalline limestone ; the 

 medial one a fine-grained gneiss, a sandstone, a slaty (? felsitic) tuff, 

 a limestone, a pseudo-jade (marked as rare), and three other speci- 

 mens (of which the bulk of the moraine is said to consist), viz., a 

 crushed gneiss, a sandstone, and a slate. 



About this point a marked change takes place in the scenery. 

 From the higher part of the Biafo glacier the mountains are charac- 

 terised by needle-like forms ; further to the east, though lofty, they 

 are more rounded in outline. In this part Crystal Peak rises on the 

 right bank of the Baltoro glacier. From its southern slope come 

 (order uncertain) t nn e-grained gneiss, a tcalcitic quartz schist, a 

 tdark mica schist, fdolomite, and fliniestone (both crystalline), a 

 ffine-grained gneiss, and another gneiss (crumpled). A specimen from 

 the summit of Crystal Peak unfortunately consists mainly of crystal- 

 lised quartz, but to this a little brecciated rock adheres, some frag- 

 ments in which effervesce slightly and may be limestone. The mass 

 of practically unaltered sedimentary rocks, of which the moraine has 

 already given ample evidence, may therefore include the Crystal 

 Peak. On the ascent to White Fan Pass, south-east of the same 

 peak, were collected a tmica syenite, and a crystalline but fine- 

 grained fwhite dolomite. A greyish -^crystalline limestone occurs, 

 it is said, apparently belonging to a mass of green rock, in which are 

 thin seams of fnoble serpentine. Halfway up to this pass the strike 

 is recorded as S.E., the dip being 75 to the south-west. A diorite 

 comes from the Angle Peak, i.e., that which rises from the above- 

 named mass west of the Godwin- Austen glacier. 



The moraines from Gusherbrnm give a sandstone and earthy lime- 

 stones. The right bank of the Throne glacier fphyllite, fargillite, 

 flimestone (these three being associated), fslate, and a flimestoue 

 breccia (this, however, might be a fault product). From the left 

 bank of the same glacier (whether in situ is uncertain) a fine- 

 grained gneiss, a granite, and a dolomite (the last is said also to 

 occur on the Golden Throne). The strike in the mountains by the 

 glacier is said to be 7 S. of E.S.E. (dip about vertical) and this 

 continues all along the valley. The moraine starting from the 

 western foot of Golden Throne affords sandstone, grits, and cal- 

 careous grits (both schistose), limestones, and dolomite, and the 

 peculiar felstone described above. Mr. Conway states that the last- 

 named rock occurs on the mountain, and appears to form bands in the
