length is very distinct, resembling the grain of bamboo or 
cane. Its streak greenish gray. Insoluble in nitric acid. 
The ore itself has but little of the metallic look » and does not 
move theneedle. External colour, dark brownish dirty red ; 
Streak, dark fine red ; powder, the Same, very fine and ra- 
ther smooth. 
The streak and powder are uncertain, being sometimes as 
above, atothers the streak is brown grey, as well as pow- 
der, the hornblende being so intimately mixed with the mass, 
The results of fusion also vary. Alone it does not fuse on 
charcoal, but blackens with borax 3 the dark powder gives a 
dull red opaque glass ; in the oxidating flame, wine yellow ; 
in the reducing flame fine dark (green ?) colour, which be- 
comes more green on eooling. 
This variety does not appear to be very common, it fs q 
curious specimen, 
N°. 1L.—Mountain ore (cated also take ore,) from the 
mountain it almost composes being near the lake, Marmora, 
This ore is a very massive looking variety with an even 
fracture and argillaceous appearance. In nitric acid insoly- 
ble. Colour of fracture, iron black or steel gray ; it is gene- 
rally coated by alight crust of brown oxide, Powder by 
file black ; streak, metallic. Moves the needle, and is evi- 
dently earthy magnetic oxide ef iron, 
This ore is very abundant at Marmora, and js used fox 
making the best bar iron there, It is probably inexhaustible, 
N°.1V.—Red ore, ar ochrey red oxide of iron, Marmora, 
This has an earthy aspect ; strongly soils the fingers of g 
deeper indian red than its own external colour, which ig 
dull brick red, byt when cut fine indian red. #racture earthy. 
Powder dark red. Streak red and shines a liitle. Lasily 
cutand broken, Nitric acid changes the colour of the mass, 
Or appears to discharge it. No other effect from dropping 
the powder into nitric acid than a metallic scum arising 
and floating on the surface,
