336 GEOLOGICAL NOTES — HONEYMAN, 
Arisaig “ Archeean,” or the Archean of Cape Breton, the Cobe- 
quid Mountains, &e. 
2.—MAGNETITIC. 
Through William Ross, Esq., Collector of Customs, Halifax, I 
have received a specimen of magnetitic sand from Cape Breton. 
Of 100 grains, the magnet separated 15. The remainder largely 
consists of garnets and amethyst (?), and possibly titanite ; gold 
is wanting. It is possibly derived from the Archean erystal- 
tine rocks of Coxheath. The locality where it is found being 
Ball’s Creek. It is said to be in considerable quantity. I have 
not yet seen any garnets in the rocks of this series, either in 
Nova Scotia or Cape Breton. Magnetite is found. Paper “ Arche- 
an Gneisses of the Cobequid Magnetitic, 1880-1.” 
3.—MAGNETITIC. 
I am indebted to 8. D. Macdonald, F. G. S., for the specimen 
which I am now to describe. It is from Cape Rosier, P. Q. Its 
weight is 65 grains. Of this, about 10 grains are taken up by 
the magnet. The remainder consists chiefly of garnets and 
amethystine grains. It is very like the Cape Breton specimen. 
Boulders were collected in the same locality. These are of gran- 
itic and syenitic gneisses. In the one garnets are seen, and 
in the other grains of magnetite. So that the rocks that fur- 
nished these boulders, in all probability, are the sources of the 
sand of our specimen. It is therefore of Archzean (Huronian) 
origin, like the Cape Breton magnetic sand. 
4.—MAGNETITIC. 
There is yet another specimen in the Museum collection to 
which I would refer. It is several years since I received it. It 
was brought for the purpose of getting my opinion of its value. 
Its mineral constituents are the same as of the three last de- 
scribed, but it far excels these in the proportion of magnetite. 
It covers the magnet very readily. I think that this was the 
reason why I did not receive definite information regarding its 
locality. If the locality is not in Newfoundland, it is in some 
part of the Labrador coast. There is a piece of magnetite in the 
specimen. It is doubtless of Archean origin.
