stone bed, he had found the overlying Gneiss dipping very 
evenly to the West, as it would do if such were the case; and 
he suspected that there is a similar eastward dip on the other 
side, though the rock was covered up from observation. 
The President, Dr. J. S. NEWBERRY, made some remarks on 
Titaniferous Iron Ores, illustrated by a specimen, from West- 
port, N. Y. It unfortunately happens that many of the Mag- 
netic Iron ores so characteristic of the Alleghany belt, the 
Adirondack, and Canada, are so largely contaminated by 
Titanium that they are practically worthless. The deposit 
from which this specimen came lies just upon the shore of 
Lake Champlain and would be of immense value were it not 
for the quantity of Titanium it contains. In Canada more 
than half the Magnetic Iron ore is ruined by Titanium. Some 
of the largest and most accessible of the deposits of Magnetic 
Iron known come into this category, and any one who will 
devise a method for working these ores successfully will en- 
rich, not only himself, but whole communities, and confer a 
great benefit upon the world at large. The percentage of 
Titanic- Acid in the Canadian Titaniferous ores varies from fifty 
to a fraction of one per cent. The Kane bed, north of 
Coburg, contains eighteen per cent. Titanic-Acid. The ore of 
South Crosby, on the Rideau Canal, about eight. The great 
bed of the bay of Seven Islands thirty four per cent. That 
of the bay of St. Paul’s, ninety feet in thickness, contains forty- 
eight per cent. of Titanic-Acid. On the north shore of the 
lower St. Lawrence, at Moisie, are great deposits of Titaniferous 
Iron sand from which large quantities of Iron are now made 
by the bloomery process, probably the only case known 
where Titaniferous Iron ore is profitable worked alone. The 
reason why this ore can be successfully treated, seems to be, 
that it is composed of intermingled grains of Magnetite and 
Ilmenite. Of these the Magnetite, being much the more fusi- 
ble, is melted, allowing the Titaniferous Iron to pass up in the 
slag. In such cases the two varieties of ore may be separa- 
ted by the magnet, and this is now readily and cheaply done 
by a machine invented by Dr. Larue, of Quebec. By using
