The susceptibility of air being known - practically it was negligible in these experiments - that of liquid oxygen can at once be found.
It appears, therefore, that liquid oxygen is by far the most strongly paramagnetic liquid known, its susceptibility being more than four times greater than that of a saturated solution of ferric chloride.
Nitroxyl fluoride, NO 2 F, is formed by the action of fluorine on nitric oxide at the temperature of liquid oxygen (H.
Fleming and Dewar determined the susceptibility of liquid oxygen (Proc. Roy.
