SCIENTIFIC ANO INDUSTRIAL

A study of partially -incubated eggs
with double yolks has been made by
a French experimenter. The results
disprove the general notion that dou-
bic chickens are produced from two
yolks under pressure. as IN the two
cases observed OF double embryo the
monstrosity came from II of the
yolks quite independently of the
other. In one of these cases the sec
ond yolk produced a single chick.
thus illustrating III one egg two kinds
of twins-two young ones produced
together, and two from a single egg
cell.
At q recent meeting of the Paris
Academic des Sciences a communion
ton by NJ. Georges Claude was made
on the explosive power Of acetyleno
at very low temperatures. Tho solu-
bility OF acetylene IN acetoDe increases
very rapidly As the temperature dl-

Centigrade iissoiying more than 1000
volumes OF the Gas. 4 PLATINUM wire
may be kept at 4 red heat IN this So
luton without any explosion taking
place. Liquid acetylene at so de-
srees behaves admirably.
Professor George Forbes says it is
worth the while of users of power.
and especially goll miners, to look
into the relative cost Of steam and
electro-hydraulic works, even when
the transmission IS for a very long
distance. He holds that many II gold

the coast, Professor Forbes found 1t
more economical 10 generate power by

Dwellers along the River Spey III
Scotland complain of the killing of
the fish, and other injurious effects,
produced by effiuents from the distil-
leries along its banks. The question
how the Spey, and other rivers SINH
larly situated, may be protected from
such pollution Is being discussed.
One interesting suggestion is that the
deleterious products of the distilleries
might be gotten rid of by being blown
high in the air in the form of mist.
It is asserted that the atmosphere
would not be iniuriously affected Ill
this way. and that there would be no
perceptible increase in its moisture il
the mist were blown to a sufficiently
great height. At q height of 200 feet,
it Is calculated, about eight gallons of
the Objectionable liquid might be
sprayed into the air every minute
without being noticed by the inhabit-
ants Of the surrounding country.
Owing to the cutlery AGAINST the
dangers experienced in the manufac-
ture of phosphorus matches, a French
Government commission was APP
pointed in 1895 to find a substitute for
6 yellow phosphorus. After consider
able search and investigation nothing
was found to answer the purpose, IN
til two Of the chemists of the State
mandatory submitted samples Of
matches of their own invention, in the
making Of which phosphorus sesqui-
. sulpuide and chlorate Of potash were
used. The sesqui-sulphide IS a gray
yellowish substance prepared by
+ heating amorphous phosphorus,
which is non-poisonous, and sulphur.
The combination with chlorate OF
:. potash makes q match which ignites
, at 203 degrees Fahrenheit, and on
, sequcntly has only to be rubbed as
! any ordinary match. 1t burns quiet
5 ly, and the general public does not
g notice any essential difference IN the
new matches from those it has been
, accustomed to use. They are not
poisonous, and to effect death q would
4 be suicide would have to eat the ends
q OF some G000 matches.
a The Demand For Human Hair.
t Five tons of human hair is required
annually by London dealers III that
commodity. Most Of it comes from
France and Italy, although there are
C consignlnents from all over the world.
Is At Limoges there IS an annual hair
market and peasant girls from the
country round dispose of their locks
