Monday, 2d May 1864. 
Professor LYON PLAYFAIK in the Chair. 
Some of the foUoiving Communications were read : — 
1. Unpublished Letter of the late Professor Dugald Stewart. 
Transmitted by John Small, M.A., Librarian to the Uni- 
versity. Communicated by the Eev. Dr Stevenson. 
The letter which Mr Small has sent to the Eoyal Society, and 
which, at the request of the Council, I have the honour of bringing 
under the notice of the meeting, was acquired by the University 
in 1861, at the sale of the MSS. of the late Very Eev. Principal 
Lee. It is by no means destitute of historical importance, though 
its main value for us, may rest on the consideration that it was 
written directly from the scene of the convulsion which it describes, 
by Professor Dugald Stewart to the Eeverend Archibald Alison. 
As a zealous student of political philosophy, Mr Stewart took a 
lively interest in the early stages of the French Eevolution, He 
accordingly visited Paris both in 1788 and in 1789; and while 
there he maintained an active correspondence on the subject which 
engrossed him, with his friend Mr Alison. Of this correspondence 
five letters, unconnected with one another, have been printed in 
the Appendix to Professor Veitch’s Memoir, which forms the first 
article in the tenth volume of Stewart’s collected works. These 
five are dated, 27th August 1788, 10th May 1789, 30th May and 
4th June 1789, 27th June 1789, and 17th September 1789.
