These papers have been already published. 
The Academy have received during the past year many interesting 
communications, notices of which have appeared in our Proceedings. 
In Mathematics we have had communications from Sir William R. 
Hamilton, Rev. Professor Graves, and Mr. Stoney. 
In the Sciences of Observation and Experiment, from Dr. Kinahan, 
Professor Jukes, Professor Haughton, Professor Jellett, Mr. Donovan, 
Professor Greene, and Mr. Jennings. 
In the department of Medical Science the Academy will remember 
that an interesting Report on the remarkable case of M. Groux was laid 
before us by a Committee which had been appointed to investigate the 
matter. 
In Polite Literature we have had communications from Mr. Crof- 
ton and Mr. Drennan. 
In Antiquities, from the President, Mr. Wilde, the Archdeacon of 
Ardfert, and Dr. Reeves. 
It was with very great regret that the Council found themselves 
obliged to suspend all works connected with the Second Part of the 
Catalogue of our Museum; but the exhaustion of the fund which had 
been appropriated to the purpose of completing it left them, unfortu- 
nately, no alternative. Conscious, however, that so important a work 
should not remain unfinished, the Council have taken the only means 
in their power for completing it, by recommending the Academy to 
open a subscription for that purpose. This recommendation having 
been adopted by the Academy, it now rests with the individual mem- 
bers to decide whether or not this work shall be completed. It is 
highly desirable that the registration, at least, of the articles in our 
Museum should be finished, as this is necessary for their safe keeping. 
The Council would remind the Academy that Mr. Wilde has de- 
voted much of his valuable time to this object, and has collected a great 
deal of important information on the history of various articles in the 
Museum, which, but for his zeal and industry, would, in all probability, 
have been entirely lost. The best and almost the only way in which 
the Academy can manifest their gratitude to Mr. Wilde-for his disinte- 
rested services will be by contributing to a fund which will enable him 
to continue and (if the fund collected be sufficient) to complete his un- 
dertaking. 
Four Cunningham Medals were presented during the past year: two 
in Science, one in Polite Literature, and one in Antiquities. 
In the department of Science the medals were awarded to the Rev. 
George Salmon, for his ‘‘ Researches in Analytic Geometry ;”’ and to 
Mr. Cooper, for his ‘‘ Catalogue of Kcliptic Stars.” 
In Polite Literature, a medal was awarded to the Rev. Dr. Wall, for 
his ‘‘ Researches in Oriental Literature,” and in Antiquities, to the Rev. 
Dr. Reeves, for his edition of ‘‘ Adamman’s Life of St. Columba.” 
The Council have much satisfaction in stating that the finances of
