Mr. Chairman, Ladies and Gentlemen,—Before I begin my paper, I wish to say how highly I value the privilege of putting my ideas before you on this occasion. As regards my subject, I might say that I have given it a good deal of thought for a long time past, and it is one which I should probably not have worked out but for the kindly encouragement at the outset of your late lamented President, Sir John Stainer. I may also say that your esteemed Secretary took me by surprise some ten or twelve days ago by asking me if I were prepared to come forward at this time. I was not altogether prepared, but I shall endeavour to do my best.
