Gentlemen,—Each member of this Association, if placed in the honourable position of President, would, I presume, have his own special views as to the nature of a Presidential Address, although the selection of a subject might be attended with difficulties. Within the last few years you have wisely determined that such Address shall be a theme for discussion, and it appears to me expedient under these circumstances that the President should aim at bringing before you material of a debatable character, and at the same time that he should endeavour to suggest subjects which may lead to further progress in the special work we all have at heart. Such thoughts give rise in the first place to a feeling of personal inability, and next to a sense of the great responsibility which you have placed upon me. It seems presumptuous on my part to attempt to point out to you new fields of labour, yet I cannot help thinking that the assumption of less reticence as to our individual experiences, and the conclusions such experiences force upon us, would tend towards the development of greater and more beneficial progress.
