NEW YORK BOY INJURED

CAMBRIDGE. Mass, May 19.-Atherton
Kinsley Dunbar of Cambridge, Mass.
fellow in research in cryogenic en-
gineering at Harvard. and William
Connell of Cambridge. a carpenter.
were killed instantly late to-day by the
explosion of tank of liquid oxygen
in the basement OF the Jefferson Ply
sical Laboratory at Harvard. An as
sistant and six other students were in
jured.
Mr. Dunbar, who was engaged in an
army test experiment in liquifying
oxygen, was blown to pieces. Connell.
who was working in an adjoining
room, was killed by the shock of the
explosion.
Two of the injured students were
graduates assisting Mr.. Dunbar in re-
search work. The others. freshmen,
were taking a lecture in a classroom
above and were hurt when the rush
of air blew the floor out.

According to the college office the ex-

Graduate students who had been as
sisting Mr. Dunbar in his experiments
advanced the theory that the accident
was due 10 a leakage of oil into the
LIQUID oxygen tank. Mr.. Dunbar had
just oiled a valve at the top OF the tank
when the explosion came.
On the floor above Mr.. Hoover was
conducting a course in physics. Demon
strating TO class OF freshmen an effi-
cheney motor generator. According to
the assistant there was a sharp sound
like the report OF a gun. and then the
floor OF the classroom rose. and there
was n rush OF gas and smoke. The
generator fell from its stand on Mr..
Hoover's foot. crushing II badly. Four
members OF the class suffered injuries
to feet and ankles. Windows on two
floors OF the building and In the Cruft
Laboratory nearby we're shattered.
Mr.. Dunbar had just recovered from
injuries caused by similar though
less powerful explosion more than a
month ago. fie was In a hospital for
some time and returned to his duties
only two weeks ago. According 10 men
engaged In research with him he was
trying to work out cheaper process
for the manufacture Of certain gases
Tor commercial use and also was inves-
tigating vapor pressure
