PROCEEDINGS OF SOCIETIES. 
that the intruded rocks were injected as horizontal sheets, gently lifting 
and floating up the rocks above them, bnt not otherwise tilting or dis¬ 
turbing them,—and that the igneous rocks were all there, and all con¬ 
solidated into their present condition, before the commencement of those 
great movements of elevation and disturbance by which the Cambro- 
Silurian rocks were tilted and inclined, not only in the south-east of 
Ireland, but simultaneously over all the British islands, and throughout 
Scandinavia and the north-western parts of Europe. 
Dr. Griffith observed that in a paper recently read to the Society, 
respecting a visit made by him to Arklow Bock many years ago, he had 
put forward views somewhat different from, although on the whole re¬ 
concilable with, the statement of Mr. Jukes; and expressed his general 
concurrence in Mr. Jukes’s views, although he confessed he felt still dis¬ 
posed to uphold the old-fashioned metamorphic theory. 
Professor Haughton asked whether the occurrence of a band of 
genuine granitic elvans in the centre of the rocks of this district might 
not render their highly metamorphic condition explicable; whether he 
considered them to have been originally of simply aqueous, or of trap- 
pean ash origin. 
Mr. Jukes having replied satisfactorily to the several queries pro¬ 
posed, Dr. Alexander Carte read a paper “ On a Jaw and Tooth of Ele- 
phas Cliftii, from the Sub-Himalyas.” 
Dr. Griffith then moved that the marked thanks of the Society be 
given to the Provost and Board of Trinity College for their kindness in 
allowing the Society the use of so spacious and convenient a room for 
their meetings. 
Carried by acclamation. 
The meeting then adjourned until the second Wednesday in Janu¬ 
ary, 1858.
