ward Forbes. But it was in the long series of papers published by his 

 friend, the lateWilliam Thompson, Esq., that Dr. Ball's extensive know- 

 ledge of the Irish Fauna was particularly manifested. These papers, 

 with additions, were afterwards collected by Mr. Thompson, and in part 

 prepared for publication, under the title of "The Natural History of 

 Ireland." Three volumes, treating of the Birds, were published during 

 the lifetime of their lamented author ; the fourth volume, which ap- 

 peared in 1856, was a posthumous publication. Throughout its pages, 

 the name of Dr. Ball is of continual recurrence ; and he not only gave 

 his valuable aid to its revision as it passed through the press, but contri- 

 buted additional information, which is appended as foot-notes. 



"Cast thy bread upon the waters," would seem to have been Dr. 

 Ball's motto, so desirous was he at all times to impart the knowledge 

 which he by ceaseless diligence had acquired. He not only freely gave 

 from his accumulated stores, but he inspired others with an impulse for 

 the further diffusion and advancement of science. That impulse yet 

 survives, and will assuredly produce good results, though they may not 

 be manifested until " after many days." 



The community in which he lived lost by his death a worthy citi- 

 zen ; yet his name will long be remembered beyond the circle that in- 

 cluded his personal relatives and friends. 



The hard-working mechanic and the toil-worn clerk shall in future 

 years visit, with their families, the Zoological Gardens, as they do now. 

 When enjoying amid its attractions the innocent prattle of their chil- 

 dren, such men will naturally ask, " To whom do we mainly owe the 

 existence of this Garden, and the penny admission, which makes it avail- 

 able to us ?" Let some simple inscription, some unostentatious tablet, 

 answer the inquirer, and tell to him and to his children that the name 

 of their benefactor was Robert Ball.
