interest with which he addressed his inquiries to the authors of the memoirs 
there read, in order to develop a clearer idea of the theories advanced or the 
facts recounted. Nor will they fail to recall the kindliness of his manners, the 
promptness to oblige, and the perfect good-will which marked all his conduct 
toward his colleagues. It was on the 17th of January last that he terminated, 
at the age of 92, his long and admirable career. 
The loss thus sustained by the Society has found a compensation in the acces- 
sion of two new members, MM. Perceval de Loroil and Casimir de Candolle. 
In connexion with the latter nomination, it may not be amiss to say that no 
more agreeable duty could have attended the discharge of my functions as 
president than that of signing the diploma of membership of the son of the 
excellent colleague who is to succeed me in this chair, and grandson of the 
distinguished master who once honored me with his counsels, his instructions, 
and his friendship. 
After what was said by my predecessor, M. Pictet, in the annual report of 
1860, respecting the incorporation into our body of the Free Associates, I need 
only add that we have had no cause to regret this change in our organization. 
The regular attendance of several of them has contributed much to the inter- 
est of our sessions, and we may hope that they will in future take even a 
still more active part in our deliberations and enhance their favors by occa- 
sional communications. Alas, while writing these lines I cannot forget that 
two of the names which we had gladly inscribed on our lists will next year’be 
no longer found there, and that the void which they leave is but an imperfect 
symbol of the greatness of the loss, not only to their families and friends, but 
to the community and the country. The two free associates whom we no 
longer possess are the former syndic, M. Barde, and Dr. Rilliet.
