Among the recently proposed appiiea-
lions Of luminous paint Is the making OF
luminous tape for military use in mark
ing out projected earhworks a; night.
Such tape would expose no ray Of light
to the enemy. The paint has also been
placed on glass and used for inspecting
the interior Of boilers, has been applied
TO compasses and to water-buckeis to make
them visible in the dark, and has even
been placed on the back of glass with
which an English railway carriage has
been lined.
A Scottish physician declares that Of

Mr.. w. Mattieu Williams states that
be drew attention in 1877 to the fact that
the North Cape is not the northernmost
extremity Of Europe, as it is generally
believed to be. A low tongue Of rock,
called Knivskjieroddcn or knivskjalod
den, about mile 10 westward of North
Cape, projects further north than the
Cape itself, This insignificant appearing
rock hardly seems to deserve the name

The natives Of America were acquaint-
cd with the use Of colors at very remote
period. Their FIRST coloring materials
were undoubtedly supplied by the ochres,
soot-black, and lime, while experiment
gradually taught them to extract ycgeta-
BILE colors from leaves, fruits, roots, stems
and seeds. An animal coloring matter
like the Tyrian purple, was yielded by
sea-mollusks. The Peruvians and the
Me1icans were able to dye their cloths,
and Peruvian mummy-w rappings have
been found after having been buried for
centuries to still retain their primitive
color.
