When the subject of this address was decided upon, I had an idea that I might bring before the attention of this meeting many unfamiliar facts in connection with a most important, possibly the most important, branch of musical composition; but in the interim there has appeared the beginning of an article in Mr. Grove's Dictionary—which, although it is not yet signed, I guess from internal evidence to be the production of Mr. Rockstro—which anticipates many of the novelties I might have advanced, and sets those forth in the most clear, in the most interesting, and (I can say nothing short of the highest terms of eulogy) the most satisfactory and instructive light.
