This fact is of " high geological and genetic interest," as there seems to be some general law determining these proportions and it will be very interest- ing to ascertain whether they hold good in the case of the Sudbury deposits. In the nickel ore in a few places the mineral Pentlandite (Eisennickelkies) has been discovered and in a single case.
