In this connection it should be stated that the vortex principle was also adopted in the Davis vaporizer in its original form, the particular method used in this case consisting of a fan which was caused to revolve within the vaporizer by the action of the mixture being drawn through it, and by this means caused. un- vaporized particles to be whirled out of the ingoing 6
