contains thin layers of radiate-fibrous lin)omte. In one place this 
limonite had a surface of a metallic beetle-green colour. 
As will be seen from the preceding paragraph, the ores consist partly 
Niitun- niul .imility of a mixture of braunite and psilonielane, the latter 
of the ores. mineral predominating, and partly of a mixture 
of pyrolusite and psilomelane, or of either of these latter minerals 
alone. The pyrolusite-psilomelane ore is probably more abundant 
than the braunite-psilomelane ore. 
Sample No. 38 was taken from the outcrop of the hard grey braimite- 
psilomelane ore on the west ascent up to the east peak and was analysed 
at the Imperial Institute with the foUov/ing result : — 
Sani vle No. 38.

and indicates that this type of ore consists of about 1 part of braunite 
to 2 parts of psilomelane. 
Sample No. 39 was broken from the outcrop of pyrolusite and psi- 
lomelane, the latter predominating, on top of the east peak, and for some 
distance down the east descent. The analysis made at the Imperial 
Institute shows : —
