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. 



Much as he had done, how much more might not yet have been

 October last. He received a severe injury on the head while in 

 India, which was the remote cause of his early and lam.ented death. 



Mr. Hennell, the chemical operator at Apothecaries' Hall, lost 

 his life by an extraordinary accident ; he was mixing a large quan- 

 tity of fulminating mercury for the service of the army in India, and 

 being desirous that it should be of an uniform colour, the whole was 

 placed in a large evaporating dish ; as he was stirring it, an explosion 

 of the Mdiole took place, which was attended with his complete de- 

 struction, many parts of the body being thrown to a considerable di- 

 stance. 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. 

 It gives me great satisfaction to be the organ of the Council of 

 the Royal Society in bestowing on your friend Mr. MacCullagh the 

 Copley Medal. It is needless for me to dilate on the profound ma- 

 thematical skill and exemplary diligence with which he has explained
