Although the Bust was only placed in the Hall at this time, the offer of it to the Society was made by Sir Eoderick I. Murchison in June 1871, in the following letter to the President:—MY DEAR PROFESSOR,—As it is very improbable, indeed—nay, almost a certainty—that I shall not be able to attend the meeting of the British Association at Edinburgh this year, I wish to send, as my representative, a marble bust of myself, executed by Mr Henry Weekes, R.A., and which is on the point of completion.
