Since we last assembled here, and shortly after the last meeting of the session, the British Association met in our city. Though the first meeting of that body was held at York, yet the proposals and counsels which called it into existence, and led to its organisation, emanated from Edinburgh. It originated, in fact, from the suggestions of a distinguished former President of this Society, Sir David Brewster (then Dr Brewster), aided principally by two former secretaries of the Society, Professor Forbes and Sir John Robison.
