Some of the eminent men who have preceded me in this chair have made their inaugural address the occasion for a forecast of the improvements in practice and the developments in area of the great industry in which we are engaged. Several of these forecasts have been verified by the results; in other cases they have proved to be mistaken; nor need this excite surprise. I believe that few would have predicted, when the consideration of the subject was somewhat unfortunately deferred through want of time at our Paris meeting of 1878, that the basic process would so speedily prove itself to be of such paramount value as we now know it to possess.
