"A clever chemist has invented an
automatic sensitive paint which is a
bright yellow ut the ordinary tempera-
ture. but, l.. III being brought into
warmer atmosphere, it changes color
gradually, until at 800 degrees, it be-
comes bright red. 1t returns to its
original color upon cooling and may be
heated with the same effect over and
over. 1t is suggested that this paint
may be used with advantage to detect
rise in the temperature of the frac-
tional working parts OF machinery.

There can be no doubt as to the ex-
istence of diamond in meteoric iron.
This is the first time that this precious
stone has been found in what may be
considered its primitive gangue. In all
the rocks where it has been hitherto
met with, even in the pegmatite of
India, we may see that it has been in
troduced as such during the formation
of the rock. Here, on the contrary, the
very state of the diamond, which APP
pears as fine powder disseminated in
certain parts of the meteoric iron, seems
to indicate that it has taken its origin
on the spot and has been formed during
the consolidation or the capitalization
of the mass.-C Friedel, Complies Rem
