MR. S. CARLTON-SMITH (Section President): It may seem strange to some, or at least it would have seemed strange some years ago, that a lecture on the electrodeposition of metals should be regarded as of such importance as to be given the prominence of being chosen to be placed amongst the other important subjects of production engineering at our sessional meetings. The fact is that we were asked from several quarters to include this subject amongst our lectures. It is also a fact that there is hardly a production engineer to-day who is not concerned in his production with plating or deposition of metal to preserve or ornament articles which he is daily producing.
