PROCEEDINGS OF SECTION C. 413: 
gneisses as I have described. They extend over a_ large 
area of many miles in diameter, within which rises Mount 
Leinster, one of the later plutonic intrusions of the district. The 
sequence of rocks is as far as the intrusive area is concerned— 
(1), quartz diorite ; (2), syenite porphyries and orthophyrs, and 
thus resembles the Frenchman’s Hill area, near Omeo, which I 
have already described in a former paper. 
In the section just described, I find the sequence of rocks to 
be on the whole very analagous to that at the Dargo River. 
There is a passage from the nomal Lower Paleozoic formation into 
metamorphic schists ; then a sequence of schists characterised by 
the gneisses resulting from the metamorphism by pressure of the 
massive quartz diorites, which in this case exist over a wide 
tract adjoining the former. In this case still further minute 
investigations are necessary, but for the present I think that the 
point of demarcation may be placed a little to the eastward of 
the quartzose schists, which I regard as being on the margin of 
the intrusive rocks. 
Part of the metamorphism of the sediments must be no doubt 
attributed to the large intrusive mass of porphyrite. 
The third example is near Mount Livingstone. It is centrally 
situated as regards the whole metamorphic area. It is interesting, 
because there the schists are surrounded by plutonic rocks still in 
a more or less completely massive condition as quartz-diorites, 
and granites. There is in this locality a tract of gneisses 
undoubtedly produced by the metamorphism of plutonic rocks. 
At some distance, and to the north east of the Frenchman’s Hill, 
there is a tract of mica schists, produced by the metamorphism 
of the Lower Paleozoic sediments. Thus the two groups, which I 
have endeavoured to distinguish from each other at the Upper 
Dargo and at Marengo Creek, are found here each one by itself. 
The schists at Mount Livingstone can be studied in 
Green Wattle Creek. They are distinctly bedded, more or less 
nearly vertical on a north westerly strike. The texture of the 
beds varies from rather fine-grained to comparatively coarse- 
grained, with numerous “eyes” of felspar, or of felspar and 
quartz. The character of the beds also varies from the appearance 
of a mica schist to gneiss. Details will be best illustrated by 
describing some of the samples collected. 
The first to be mentioned is a micaceous schist at the lower end 
of the gorge-like valley down which Green Wattle Creek flows 
for several miles. In a hand sample the rock greatly resembles 
some of the light-coloured mica schists which have resulted from 
the metamorphism of the sediments, as, for instance, those near the 
foot of the spur at the Upper Dargo River, of which I have 
spoken already. A thin slice, however, prepared across the 
foliations, shows that the rock is formed of alternate foliations of 
mica, which is almost wholly muscovite, quartz, and small
