If the molecules in liquid crystalline para-azoxyanisol are oriented by a magnetic field, the coefficient of heat conduction is thereby increased by (roughly) twenty-five per cent. The orientation of the molecules produces also orientation of the swarms, often called liquid crystals. Using the results of this experiment in conjunction with earlier experiments in which the flow of heat has also an orienting effect, one can state that the flow of heat decreases the coefficient of heat conduction.
