In this list are included two names of European 'celebrity — names 

 which stand in the foremost ranks of Mathematical Science, and Archaeo- 

 logical Learning, respectively. After the able and eloquent tributes 

 lately paid by our President to the memories of Sir William Hamilton 

 and Dr. Petrie, it is unnecessary for us to enlarge on the loss sustained 

 by our country, and by the republic of letters, in the deaths of these 

 distinguished men. But we may be permitted to observe how closely 

 the labours and the renown of both were associated with this institu- 

 tion. Almost all the important researches of Hamilton were published 

 in our " Transactions" or " Proceedings," from the "Essay on Systems of 

 Eays," which first established his reputation, and for which he obtained 

 our Cunningham Medal, to the " Theory of Quaternions," which was 

 the latest product of his genius. The first hints of this Theory were 

 given in communications read before the Academy ; and up to the close 

 of his life, he continued to bring before us, from time to time, the newest 

 developments and applications of the method. In like manner, those 

 works on which Dr. Petrie's reputation is principally founded — the 

 treatises on the Eound Towers of Ireland, and on Irish Military Archi- 

 tecture — were prize essays written on subjects proposed by the Academy ; 

 while for that on the History of Tara one of our Medals was awarded 

 him ; and our members do not need to be reminded how often, to the 

 very last, he took part in our discussions, and by his archaeological 

 learning and skill threw light on the questions which came before us, and 

 illustrated the objects of Art or Antiquity which were exhibited at our 

 meetings. 



Another well-known and much-respected name appears in our Obi- 

 tuary list — that of the Eev. Dr. W. H. Drummond, who was for a long 

 time a member of our Council, and Librarian of the Academy. He was 

 an ardent lover of literature, and possessed much solid learning, as well 

 as general cultivation and refined taste. His mild and amiable nature 

 endeared him to his friends; and when, in 1861, in consequence of his 

 age and increasing infirmity, he retired from the position he had held
