SCIENTIFIC lNTELLIGEyCE.



A second exhibition Of the light educed by mix
turc OF pure oxygen with street hydrogen gas was
given yesterday afternoon In the presence vi several
distinguished gentlemen In darkened compart-
ment ia the offices Of Messrs. Stems, Stevens a
French, ~ Nassau street. To produce the oxygen
gas cheaply and in sufficient quantities resort IL had
to manganesotes compounds Of manganoric acid
with bases), which are deoxodyzed at temperature
OF 500 degrees Fahrenheit by passing hot steam over
them In retorts. The oxygen disengaged Is con-
veyed TO receiver. BY this process manganates.

gas, when pa aged upon magnetism pencil In COM
binauon with the hydrogen, produces pure, soft
white light, sixteen times stronger than the ord-
nary gas or, to express 1t more plainly jet OF

It is believed that in little while II can be made
much cheaper-that Is the oxygen In combination
with pure hydrogen at the burner. and for the
reason that by a new process, for which patents
are held covering the United States by Messrs,
Storms, Stevens a French, the last named gas can
be obtained In large volumes from anthracite

oxygen at exceedingly low figures, viii place the
