 dered in collecting information, as also by placing a room in his offices at the 

 disposal of the Committee. 



Your Committee, in conclusion, have the painful duty to record the death 

 of their late Chairman, Admiral Moorsom, and the regret which they have 

 felt at the melancholy event which has deprived them of their Chairman, and 

 their sense of the great loss which has thus been sustained bj^ your Associa- 

 tion and by the scientific world at large, as well as by the distinguished pro- 



fession to which he belonged.
