The slits werefixed during the experiments with the lead reflector, at a distance of 3*15 their middle points, the lower one being 0*2 cm. above the inlet inlet was covered with aluminium foil 0*1 mm. thick, strengthened by amesh of aluminium 0*4 mm. thick placed under it, an air-tight joint beingobtained by means of sealing-wax. The apparatus was connected to a Topler pump and McLeod gauge by atube bent to exclude the
