The origin of the Association is connected with Edinburgh in undying memory through the honoured names of Robison, Brewster, Forbes, and Johnston. In this place, from this Chair, twenty-one years ago, Sir David Brewster said :-"On the return of the British Association to the metropolis of Scot“ land I am naturally reminded of the small band of pilgrims who carried “ the seeds of this Institution into the more genial soil of our sister land.” “Sir John Robison, Professor Johnston, and Professor J. D. “ Forbes were the earliest friends and promoters of the British Association. “ They went to York to assist in its establishment, and they found there the very men who were qualified to foster and organize it. The Rev. Mr. “ Vernon Harcourt, whose name cannot be mentioned here without grati“ tude, had provided laws for its government, and, along with Mr. Phillips, “ the oldest and most valuable of our office-bearers, had made all those “ arrangements by which its success was ensured. Headed by Sir Roderick “ Murchison, one of the very earliest and most active advocates of the “ Association, there assembled at York about 200 of the friends of science.” The statement I have read contains no allusion to the real origin of the British Association. This blank in my predecessor's historical sketch I am able to fill in from words written by himself twenty years earlier. Through the kindness of Professor Phillips I am enabled to read to you part of a letter to him at York, written by David Brewster from Allerly by Melrose, on the 23rd of February, 1831: ~ Dear Sir,—I have taken the liberty of writing you on a subject of con“siderable importance. It is proposed to establish a British Association of “ men of science similar to that which has existed for eight years in Ger“ many, and which is now patronized by the most powerful Sovereigns of that part of Europe. The arrangements for the first meeting are in and “ it is contemplated that it shall be held in York, as the most central city for “ the three kingdoms. My object in writing you at present is to beg that you “ would ascertain if York will furnish the accommodation necessary for so progress; a |
