The contents of each cellare summarized in Table I. The cells were filled suc-cessively through a single glass manifold attached to thegas-handling system. Before filling, each cell was firstcooled to & 20 K by a small Bowing-liquid-helium De-war. The appropriate quantity of oxygen, admitted &om a calibrated volume at a known temperature and pres-sure, was then allowed
