WE agree with Prof. Barlow that considerable refinement in technique is required to achieve gain. In addition to those points which he mentions as essential, it is necessary also to have very good thermal contact between the crystal and the magnetic core, in order that a high input current density may be used without appreciable heating of the crystal. Although only small power gains have so far been achieved, we think that the device is capable of considerable development.
