A new method of etching Oh glass
or porcelain has been patented by
IIerf RetzlafY, Of Berlin. The usual
German process consists In cement
ing sheet Of tinfoil to the surface,
which Is then uncovered for etch-
Ing by skilful cutting out OF the
pattern In the foil, and washing
away OF the cement. The improved
plan Is to perform this operation
more simply and perfectly by chem
ical means. The pattern Is printed
or stencilled In grease colors on the
tinfoil, which Is then fastened to
the glass by ashphat, and the pre-
pared plate Is placed in an acid bath
that dissOlves out the exposed parts
OF the foil. The asphalt is then
washed off, when the glass Is ready
for etching in the usual way.
BY means OF the microtome, Sill
ces OF vegetable and animal tissues
down to thinness Of about 10000
Of an inch are obtained for micro
Scopic study, Prof. Elmer Gates, OF
Washington, has now gone further
and even slices up blood cells and
microbes by cementing them in a
single layer between two glass
slides and cutting the slides apart
with a very thin blade Of copper
sharpened to the highest possible
degree. The fine grain Of the cop
per causes it to take an edge that
no razor can approach. The cells
are again cut by repeating the OPP
Grafton, and 1t is claimed that sill
ces have been made only l-lOO as
thick as the thinnest produced by
the microtome.
| Selenium, hitherto chiefly an in
teresting curiosity Of the chemists
laboratory, has been recently used
for coloring glass. When added di.
rectly to the glass In the melting
pot, it gives fine rose tint, vary
ing somewhat with the purity Of
the selenium and the hardness Of
the glass, and when the seleniun
is mixed with cadmium sulphidt
"a beautiful orange red is yielded.
The new rustpreventing pain

burg, Germany, is composed OF tn,
, perOxides OF carths OF the ceriun
group. These are incorporates

addition of a drier linseed oil boil
ed with a mixture Of boric acid an
the peroxides. Graphite, hanback,
heavy spar, ETC., may be used 70
r coloring. The paint is claimed t
$ fulfill all requirements, having sui
I ticient oxygen to insure hardenin
: of the linseed varnish, with fret

l From experiments by NJ. Rave
l it appears that 6.35 cubic feet ,
e acetylene gas generate in the 81
It engine one horse power per hou
le which is a reduction
It fuel Of two-thirds as compa
l. ed with petroleum.. The mi,
II ture OF air with acetylene b

portion reaches l.35 parts OF gas

st reaches its maximum with II vo

c. pears at 20 to l. The flashing poll
is about 900 o f. most other gas,
used for power requiring tempe

The temperature OF combustion
h much higher than that of 9TH

characteristics Of this gas.
Since the domestication Of IL

Of a half-breed combining the qua
ties Of the two animals, as IL
es mule combines the horse and tt
IS ass. The new hybrid is announc,
" by the Baron de Parama, the an

IN 1t is called, is male of bay col,

% hidden on the body by the thiC

IS sembles that of the zebra, the ia
