Appendix, 
which he afterwards became a Member of Council and Vice-President. 
It seems to have been his intimate friendship with Petrie that first led 
him to the serious study of archaeology. He co-operated earnestly in 
the establishment of the Irish Archaeological Society, founded in 1 840, 
and afterwards in that of the Celtic Society, in 1845. 
In common with all enlightened Irishmen, he had felt much disap- 
pointment and regret when the operations of the Topographical de- 
partment of the Ordnance Survey were stopped by the Government, 
after the publication of the Londonderry Memoir. In 1843 it was 
resolved to take action, for the purpose of endeavouring to induce Her 
Majesty's Ministers to sanction the recommencement and continuance 
of those operations. In January of that year the Academy appointed a 
deputation to present a memorial on the subject to the Irish Govern- 
ment. Lord Dunraven (then Yiscount Adare), acting in concert with 
his Irish friends, brought together a large and influential meeting in 
London, on the 19th of June, in the same year. The result of the etforts 
thus made was, that the then Prime Minister, Sir E,obert Peel, consented 
to the appointment of a Commission to reconsider the entire question. 
Lord Adare was a member of this Commission. Some of the leading 
scholars of Ireland were examined before it, and a highly-interest- 
ing Eeport, based on their evidence, was presented to the Govern- 
ment. That Peport was in favour of the resumption of the Geological 
Survey and the continuance of the Topographical and Historical de- 
partment concurrently with it, though on a separate basis. The recom- 
mendations, so far as the latter was concerned, were not carried into 
effect; and, in that respect, the Commission bore no fruit. But the move- 
ment in which our deceased Member had taken such a prominent part led 
to the establishment of the Geological Survey of the United Kingdom, 
which De La Beche in England and Portlock in this country h aci com- 
menced, but which, up to the period of the labours of the Commission 
of 1843, had received very little encouragement or support from the 
Government. 
On the discovery of the Ardagh Chalice and Brooches, Lord Dun- 
raven procured for us, as we have already had occasion to mention, the 
privilege of exhibiting in our Museum, for a considerable time, those 
valuable works of art. And we have reason to know that it was his- 
earnest desire that they might ere long become the property of the 
Academy. He gave an elaborate account of them in a Paper read 
before us, and which will soon appear in our Transactions. 
Por some years before his death he was engaged in preparing mate- 
rials for the completion of Dr. Petrie's History of the Ancient Eccle- 
siastical Architecture of Ireland." He had personally visited all the 
principal ruins, and had taken photographs, and made ground plans and 
measurements of them, and written descriptive notes. He made pro- 
vision in his Will for the publication of these photographs, which will 
supply a series of illustrations of Irish Architecture, from its earliest 
period down to the Norman Invasion. 
Lord Dunraven was President of the Cambrian Archseological Asso-
