described. Numerous blocks of basalt occur, as also of a dark, 

 coarse crystalline rock, which seems to consist largely of 

 pyroxene. 



iMicroscopically I have only examined a slide of the typical, 

 banded grey gneiss. It reveals nothing remarkable except the 

 combination, characteristic of the whole district, of hornblende 

 and biotite in about equal quantities. For the rest it is rich 

 in epidote of a fairly primary appearance. No distinctly granitic 

 characteristics are to be found; the secondary re-crystallization 

 reveals itself in the abundant presence of myrmekite. 



The West Coast of Liverpool Land, near the 

 southernmore of the two large glaciers that push on towards 

 Hurry Inlet. It is interesting to see how much more varied 

 the rocks appear on the west than on the east side of the 

 country. The rocks at the landing place indicated above consist 

 mainly of a series of gneisses in quickly varying layers, chiefly 

 a grey mica gneiss, and also amphibolite and mica-schist-like 

 forms. Curious is a type met with somewhat further inland, 

 which there seems to have a by no means inconsiderable distri- 

 bution. Macroscopically a marked schistosity presents itself in 

 close rows of small, red felspar eyes, and in a slreakily ar- 

 ranged green mineral. Microscopically it can be seen that the 

 rock has been subjected to very strong pressure; porphyritic 

 crystals of both orthoclase and very strongly dismembered pla- 

 gioclasel?) lie in a groundmass, which together with biotite and 

 chlorite is almost exclusively formed of irregular stalk-like quartz 

 individuals extended in the direction of the schistosity. What this 

 rock originally was, it is hard to say; in any case it shows what 

 strong transforming powers have been at work in this locality. 



In one spot a dike of fine, fresh basalt was met with. 

 Besides this there occurred, in the same district, two rocks 

 that deserve special mention. One is a limestone, part white 

 with mica and some tremolile, part malacolitiferous and some- 

 what greenish, and occuring in the gneiss in rather small quan-
