The Chairman closed the session with the following remarks:—

I have now, in a very few words, to close this session, and in so doing I beg to remind you that it is the ninety-ninth session of the Royal Society of Edinburgh. This Society, which was originally an offshoot of the University of Edinburgh, was first started, on the suggestion of Principal Robertson, towards the close of 1782. So that in the latter part of next year you will be able to announce your hundredth birthday. The Society came into existence just one year after its late distinguished President, Sir David Brewster, who was born in December 1781. While individuals pass away, age brings no decrepitude, but rather the reverse, to universities and scientific bodies.
