II has often been asserted that breath
ing oxygen quickens the action OF the
heart and raises the temperature OF the
body. This assertion has been subject,
cd 10 investigation by Naoumof and
Bieliaref, who find that the prolonged

probable influence on either the pulse
or the temperature. The experiments
we're made on dogs and on the human
subject.
