geologist was so highly valued, that the University of Dublin appointed 

 him as its Professor of Geology and Mineralogy in 1881, on the resig- 

 nation of that chair by Rev. Dr. Haughton. This post Dr. Ball filled 

 with distinction, but he held it only for a short space of time, for 

 within two years, the very congenial position of Director in the 

 National Museum was conferred on him, and to the task of developing 

 this Museum he addressed himself with his energy and single- 

 ness of heart. Yet he never lost sight of his old studies, and wrote 

 many papers on the various branches of science on which he possessed 

 special knowledge, some of which have appeared in our Transactions 

 and Proceedings. 



Of the general excellence of his work, the best guarantee is to be 

 found in his election to the Eoyal Society of London, in 1882, and in 

 the honorary degree of Doctor of Laws, which was conferred on him 

 by the University of Dublin, in 1889. With most of the Scientific 

 Societies of Dublin he stood in close and intimate relation. He was 

 for many years the Secretary of the Eoyal Zoological Society of Ire- 

 land, and took a deep interest in its maintenance and prosperity. In 

 1886 he was elected to the Council of the Eoyal Irish Academy, and 

 held his seat as Member of Council till his death, which took place on 

 June 15, 1895.
