Grubb, and within the dome erected by Mr. Grnbb for the accom- 

 modation of the great Vienna Telescope. The result of these elabo- 

 rate experiments was a Paper in the Philosophical Transactions "■ On 

 the Determination of the Constants of the Cup Anemometer by Experi- 

 ments with a Whirling Machine," April, 1878. 



Dr. Robinson was President of the Eoyal Irish Academy from 

 March, 1851, to March, 1856. He was President of the British 

 Association, at its meeting in Birmingham, 1849; and was elected 

 Pellow of the Royal Society of London in 1856. It may be truly 

 said that, in few cases has -the early promise of boyhood been suc- 

 ceeded by a more brilliant manhood. Up to the very last years of 

 his long life, in ever cordial sympathy with fellow-workers, he 

 laboured continuously and successfully in the field of scientific in- 

 vestigation, and that too in so many departments of knowledge, that 

 one knows not whether to admire more the force than the versatility 

 of his genius.
