Meetings of the Society.

Professor Calderwood, who was somewhat unexpectedly elected 
to the Chair of Moral Philosophy in our University, but discharged 
its duties with great efficiency and success ; and has written and 
edited several important works on mental science. 
Professor Heddle, who contributed to our Transactions eight 
elaborate papers on the Mineralogy of Scotland ; and whose 
extensive collection of Minerals, to the formation of which he had 
devoted the labour of a lifetime, now constitutes one of the 
treasures of the Edinburgh Museum of Science and Art. 
Robert Wilson, who possessed great mathematical ability, and 
contributed a paper to the Proceedings of this Society on the 
Contact of Surfaces, in which he employed the resources of 
geometry in the elucidation of that difficult subject. 
The Hon. Bouverie Primrose, who for many years was 
Secretary to the Board of Manufactures, and evinced the interest 
he took in the prosperity of this Society, by bequeathing to it a 
sum of <£200. 
Sir James Bain, who held the office of Lord Provost of Glasgow, 
and took with him on his retirement from the civic chair of that 
great city a large measure of personal and official popularity. 
Lord Playfair, who for eleven years held the Chair of Chemistry 
in the University of Edinburgh, relinquishing it for a parliamentary 
career, and who, as a legislator, advocated every useful measure for 
the promotion of science and education, as well as political and 
social progress. 
I cannot conclude without mentioning that, during the Session, 
one of our Fellows has been made a Knight Commander of the 
Bath, and Member of the Prussian Order Pour le Merite ; another 
has received a Knighthood ; and a third has been made a Com- 
panion of the Bath.
