Mr. Chairman, Ladies, and Gentlemen,—I must first of all apologize to you for presenting a paper which has been, I regret to say, very hastily prepared, owing to my recent severe illness, and to consequent pressure upon the time at my disposal. I must next ask you to believe that I approach my subject with great diffidence for two reasons—-firstly, the inability of any one mind to comprehend the various and multitudinous thoughts and ideas that must from time to time possess the soul of every true musician; and secondly, because of my personal inability to give adequate expression—even to my own views upon so difficult and delicate a matter as the consideration of the relative position of our Art-Science to the unenlightened or popular world.
