OstetGren's mind Is fully as Important as that
laid open by the making OF liquid dir. Air
consists OF about three narts o. NITROGEN 70
the specific gravity Of both is 30 nearly tho
same that they remain init mately mixed. But
about the liuueiyina point the difference be-
comes perceptibe. and Mr.. Ostergren eays
that 1t is. possible TO separate them by gravity
rated from milk. or the:oSyRen can be lioue-
fed. leaving the, nitrogen ttee. IL pure oxy-

and many others would develop: 10 gan be

Gunpowdcr as an explosive for guns or shells.
Mr.. ostergren has ALREADY arnlied f3r nnti
eEts Tor a gun and shall. IN which alcohol
or charcoal and liquid oxygen are to be used
for the charges. In the gun alcohol would be
used because it makes no smoke. While In the
shell charc oal would do, for the more smoke
made about the enemys position tho better
BY this system plant In fort or aboard ship
would produce the LIQUID oxygen as 1t IL
needed. and pipes would take the charge OF
oxygen and alcohol to the breech Of the gun.
The turning Of two cocks would charge the
gun after the she'll was inserted. while the load
Ing OF the shells would be equally easy.
Another idea which Mr.. Ostergren 10 deyel-
oping IL the use OF liquid air as q means to
facilitate the Ions: distance transmission OF
in Distributing eIsctrlc power 10 the resistance
CT the conductors. which either required the
use Of extremely high voltaaes. which have
again to be reduced for use, or the use Of great
Quantities OF extensive metal In the conduct
ors., 1t is a well-known fnct that pure metals.
no electrical resistance Mr.. OsterGren has
designs for an electric conductor, which shall
he kept at this low temperature by liduld air
under conditions which he believes would be
both practical and economical. Such CON
ductor he thinks. would enable. a current to
he transmitted as readily from Niagara Falls
to this city az from the Falls to Buffalo.
These" said Mr. Ostergren. are but sug-
Restons as to the possible uses OF liquid air
and the other products Of the liauefying pro-
cess. They may be developed and they may
not, The thing q value which We are doing
dreds OF persons viii come forward to develop
the uses for It. 1t 10 possible. also. that the

oxygen OF the air. N ay be used TO produce am:

solve another OF the great problems OF the
