192 Scientific Proceedings, Royal Dublin Society. 
inclusive, he gave three very elaborate and valuable anniversary 
addresses on the progress of geological science. Our Journal 
contains besides several other contributions of his. Towards the 
end of 1850 he was appointed Superintendent of the Geological 
Survey of India, which post he held until the early part of 1876. 
The important work accomplished by that survey under his 
superintendence is too wide a subject for us to give evena sketch 
of on the present occasion. Oldham was wisely averse to the 
direct correlation with each other of Indian and European forma- 
tions which are admitted to be comparable homotaxially. In 1875 
he received from the Royal Society a “Royal Medal” “for his 
long and important services in the science of geology.” His death 
took place at Rugby, where he had lived since his return from 
India. 
Robert Harkness, Professor of Geology in Queen’s College, 
Cork, was born in 1816, and died Oct. 4, 1878. He was a native 
of Cumberland. He obtained the Professorship in Cork in 1853, 
and in the same year joined this Society. He came to this country 
with an already made reputation as a geologist, having begun to 
write ten years before, and having contributed various papers to 
the Journal of the Geological Society of London, the Reports of 
the British Association, &c. He was admitted a F.RS. in 
June, 1856. During his sojourn in this country he wrote several 
papers on various subjects of Irish geology. He it was who first 
pointed out the connexion between the metamorphic rocks of 
Donegal and those of the west of Scotland. Latterly he had 
investigated a good deal the geology of his native Lake District. 
On account of ill-health he had resigned his professorship shortly 
before his death, which event deprived our Society of one of its 
Vice- Presidents. 
Walter L. Willson died March 27, 1878. He joined the Irish 
Geological Survey in 1845, and our Society in the following year. 
Our Journal contains some papers contributed by him. His survey 
work lay in the south-eastern and southern parts of the country. 
He was engaged on the first map (that of Wicklow) issued by 
the Irish Geological Survey after it had become a distinct depart- 
ment from the Ordnance Survey. This map is dated July 26, 1848. 
After remaining on the Irish Survey for twelve years, Willson, in 
the early part of 1857, joined the Indian Geological Survey, in
