A NEW spectroscope has been devised
by NJ Thollon. 1t can be readily at
tached to- any telescope. The prisms
are so connected and arranged that they
may be moved in a determined way and
so that a ray of light coming along the
axis Of the collimator reaches the axis
of the telescope only after twice trav-
ersing the whole system of prisms with
the minimum of deviation. The instru-
ment combines facilities for fully con-
trolling its great dispersive power, and
for effecting minute measurements of
1spectra. ,.-5.,i ,ns,.a.s.5.s -

Medical anI Surgical Reporter contains
a suggestive editorial on $ Color Blind
ness, its Dangers and Detection Sta
tistics show that in New England one
person out of twenty is color blind, and
the proportion is probably equally large
in other parts of the country. The edi-
tor asks, in view of these facts, whether
the railroad companies take any pains
to ascertain that their engineers, signal
men, etc., have not such a dangerous
defect of vision. Most of the railroads
in Europe subject their employees to Sc
we're tests in regard to this matter.
4 ED1soN's visit to Nevada has given
him q new idea. He thinks that the
size, character and point of groupings
of mineral lode may be determined BY
the difference of the conductivity Of
electricity, provided that the walls o1
] the lodges are lined with clay or decom
posed rock. He will test his theory or
the Comstock lode when he return!
from California. Should his plan prove
practical, instead of running long tun
nels, sinking deep shafts, or boring
here and there with the diamond drill
q miner would apply the electrica
apparatus, and thus find out how mucl
ore there is in a mine, where it lies, it
direction, and the point where its crop
