The magnetic properties OF Etruscar
| vases, lately gtudied by DIR. Folghera
tier, have not only thrown light on tho
cnrth's magnetic history. but have nf-
forded a possible key to mystery OF
ancient art, Archaelogists have had
three hypothesis to account for the
| color of these vases, some supposng
that special Kind of clay was used,
others that the clay was mixed with
fine carbon or lanipback, and still
others that the coloring matter was IN
| troduced after the vases had been
formed. To account for the magnetic
properties of the vases, they must have
been heated to more than 1870 deg c., a
| temperature to or beyond which the
clays experimental on stu retain their
| Elasticity. AS carbon mixed with clay
| disappeared at $50 deg, and fragments
| OF the old vnses lost their color at that
temperature, the first two hypothcses
| were disproved. ana the third WAS

Ordinary floors IRE condemned by
scientific men because they retain
dust, In which dangerous germs are
fostcred and made to hold their vlr-

are safer but less agreeable 10 the feet.
Nj. Captain. a French hyFienist rec
omnendB woodpulp floors, which
have no cracks, are soft to the feet,
and are bad conductors of heat and
sound, while their cost Is considerably
less than that of ordinary flooring.
1t Is believed that such floors viii prove

For detecting Alterations in checks

liquids. He paints the paper with a

brings out traces OF erased writing by
making the paper partially transparent
