A more universally applicable distilling tube is shown in Fig. 156. It consists essentially of a tiny tubulated retort with attached receiver. The liquid is introduced through the side arm which is then closed with a tiny plug of cork or rubber or by fusing. Upon heating the liquid the vapors pass down the nar- row inclined tube, are condensed and collected in the rounded receptacle. To prevent loss the narrow tube between retort and receiver may be wound with wet filter paper. The distillate
