The neck was fitted with two-hi i rubber cork carrying gla^s tubes, one admittingmsr to the bottom of the flask from a small glass externw, constant flow adjustable at any desired level, the otherselected with the reaction tube through i-io. water seal. jtie correct proportions of gas and air were determinedVrial for each set of experiments, solution of the gas inw;r being prevented by a layer of oil. Experimentsired that no appreciable alteration of strength tookpile on allowing the gaseous mixture to stand over-night. (2) Reaction Vessel: (a) Heat Jacket.—A copperglycerin bath, heated by Argand burner, and jacketed withasbestos card to lessen radiation. (6) Reaction Tube.—A U-tube with 1-in. bulbs on thetwo limbs.
