logia' and ' Vetusta Monumenta' for proofs of his varied learning, his indefatigable zeal and industry, and his careful accuracy on every one of the many subjects which he touched. His last and perhaps one of his most valuable communications to the Society of Antiqua- ries, of which he was one of the brightest ornaments (I allude to his paper on the Painted Chamber at Westminster), was completed just before his death. I must not omit to refer also to those beautiful works, in which he so carefully and ably illustrated the history of the ancient and curious seat of his own family, Hengrave Hall, and that portion of Suffolk in which it is situated. Throughout all these varied and laborious pursuits, he displayed not only all the qualifica- tions of a most able and careful antiquary, but also a disposition the most kind-hearted, and a tone of mind the most courteous towards the opinions and feelings of others, as well when differing from them in opinion, as when compelled to notice their errors in the same path of antiquarian learning.

He was an eminent chemist, and had furnished two papers to our Transactions.
It is now. Gentlemen, time for me to perform the most agreeable part of the duty which fails to the lot of a President on your Anni- versary — that of giving the Medals awarded by the Council. As we have not the pleasure of seeing here today Mr. MacCullagh, I shall beg Mr. Wheatstone, as his friend, to transmit his Medal to that gentleman.
Mr. Wheatstone.
