a. announced IN the Journal der Goldschnsiedksast
for producing gold-like alloy from copper and an
timony. one which. even II exposed for some time
to the action of ammoncal and acid vaporu, does
not lose its gold color The Journal says that 10 i'd
mirable is the product in question that II b
rolled and worked like gold without containing the
slightest admixture OF the Same, besides being far
less costly than other precious and senipreofous
metals as we'll as the compounds and alloys used
o. substitutes for these. Briefly. this alloy consists
OF copper and anthony in the approximate ratio Of
400 10 g. and ia realized by adding 10 molten copper
as IL has reached certain degree Of heat
the said percentage Of anthony. and when tho lat
ter has likewise melted and entered into intimate
union with the copper. some charcoal ashes, mag
nesium and lime-spar arc added 10 the mass whom

the action of such O material admixture Of hux II
not entirely apparent, the alloy Is said 10 lose
thereby certain porosity otherwise present and an
exceedingly great density OF the cast metal 10 Oh

The scientific difficulties encountered in all attempts
to create life" are foroibly presented in contri-
button to the NORTH american ReufetD by Prince
Hrapotkin. His opinion Is that the main interest In
this line now lies not so much in adding q new
product TO the already long list Of chemically pre-
pared organic substance in catching tho secrets
of the tiny living laboratories in the vegetable and
animal cells. investigation reveals the fact that u
the present time. about one hundred and eighty
different acids aromatic OILS, fats. oolorine matters
and so on-whioh Gro only found in nature pro-
ducts Of vital activityhave already been prepared
in various Laboratories ont OF Inorganic matter
that in fact. of them already fabricated in
this way for trade. and every year brings some new
achievement in the same direction. It need hardly
bs said that this Is new field Of research. Indeed
NJ far back a 1929 the news that wohler had
obtained. out of Inorganic stua. certain substance
urea, which occurs in nature distinct product Of
vital activity in animal life. upset current ideas.
After this. Rerthelot proved that tho ynthess Of
organic bodies must be pursued and may be
achieved in . quite systematic way. going step By

An immense and constantly growing commercial
industry has boon developed in southern Europe
namely, the making OF mncaroni. vernioeri

ton. sngularly enough. the United States Consul Al
Lyons declares that, AZ yet no American wheat has
beon found acceptable to manufacturers in this Line
the requisites for the best qualities being u hard
grain. having . large percentage Of gluten and q
small one OF starch. The statement comes from
an American chemist living near Lyons that the
wheat most sought after for this purpose
comes from Algeria, and . fair article 10 found in
