1.—NOTES ON THE METAMORPHIC ROCKS OF OMEO. 
By A. W. Howirt, F.G.S. 
lw the memoir which I presented to this association; at its last 
meeting, I noted the results of my investigations up to that date 
into the origin, formation and structure of the crystalline schists of 
the Omeo district. Since then, I have continued my work by an 
examination of a considerable number of thin slices prepared from 
samples which I had collected in typical localities. I now propose 
to submit to the association the further results of this enquiry, 
in anticipation of a more complete discussion of the data ata 
future time in the publications of the Department of Mines of 
this colony. 
I now select for illustration three localities, which will afford 
some light on the obscure questions involved in the consideration 
of the mode of formation of these schists, and their relation to 
the sedimentary rocks with which they are associated. 
One locality is on the western margin of the metamorphic area 
at the Upper Dargo River, another on the eastern margin, 
between Mount Leinster and the Limestone River, and the third 
at the base of Mount Livingstone. In each of these places I 
have carefully examined natural sections which cross the strike 
of the schists, and have then studied thin slices prepared across the 
foliations of the collected samples. It will not be necessary for 
the purpose of this paper to do more than to detail the general 
results of this study, with special reference to certain typical 
examples, leaving fuller details for the future, when the quanti- 
tative analysis of certain of the rocks will have enabled me, 
possibly, to speak with greater certainty as to the particular beds 
in the sections, which may be referred to the group of metamor- 
phosed sediments, rather than to the metamorphosed plutonic 
rocks.
