OF exploration pure and simple very
little remains to be done. The charm
of TRAVELLING through and describing
an entirely new country which may be
practically serviceable to civilized
man has been taken from us by our
predecessors. though limited regions

Polar regions are in a somewhat spec

But knowledge of the past history of
our globe-fit study for human thought
can be gained only by study of the
portions still under glacial conditions.
A method of detecting the presence
OF aniline or salicylic acid in foods
has been developed by c. Laval.

Some highly scientific results have
