We dined at Sir Alexander Gordon's. The Provost, Professor Ross, Professor Dunbar, Professor Thomas Gordon, were there. After dinner came in Dr. Gerard, Professor Leslie, Professor Macleod. We had little or no conversation in the morning; now we were but barren. The professors seemed afraid to speak.... I talked of the differences of genius, to try if I could engage Gerard in a disquisition with Dr. Johnson; but I did not succeed.
