15 
rocks from the Silurian series. He also alluded to the remark made by 
Mr. Griffith relative to the associated igneous strata, and stated that he 
had found them to he similar in composition with those of the "Welsh and 
eastern Irish schistose rocks, as would he seen from several analyses 
which he had some time since laid before the Society, especially noticing 
those occurring at Beenaunmore, discovered by Mr. Boot, of the Geolo¬ 
gical Survey; and Mr. Haughton thought that a lengthened continu¬ 
ance of peculiar igneous action during given periods of deposition will 
argue contemporaneous similarity of sedimentary condition. He had 
examined the Pomeroy district, and he agreed with Mr. Griffith respect¬ 
ing the interstratified igneous beds; also believing from his own obser¬ 
vation, that the strata of the summit of Carrantuohill and of the Hag’s 
Glen were of true Devonian age. He considered that the alleged un¬ 
conformity between the upper and lower Silurians should he found 
very universally occurring before it would become entitled to occupy a 
place beyond suspicion; as mere overlappings or exceptional disarrange¬ 
ments were liable to be substituted for true unconformities; and he 
founded the claim to which Mr. Griffith’s generalizations and reasoning 
were entitled upon their intrinsic merit, as well as originality, and not 
upon the prestige of his name or authority, as Mr. Griffith had never 
presumed upon any adventitious advantages which the well-deserved 
reputation, and high character which he had so long enjoyed, might 
confer upon him. Mr. Haughton also stated, that the value of lithological 
character in the identification of strata ought never to be wholly neglected. 
Mr. Kelly adverted to the vertical strata of the Curlew Mountains, 
and remarked upon the occurrence of Silurian fossils in them, consider¬ 
ing that they were similar to those of the Pomeroy, Clew Bay, Killary, 
and Glengariff districts. He stated that he could see nothing in Mr. 
Griffith’s paper with which he could disagree, except that, in his opinion, 
the Old Bed. rocks of Carrantuohill were not separable from the un¬ 
derlying series; he, however, should say, that the views which he had 
just heard read were those which Mr. Griffith had always consistently 
maintained. 
Professor Haughton then exhibited a fine specimen of the head of 
Oreodon Cullersoni from Nebrasca, IT. S. A., accompanying the exhibi¬ 
tion with general explanatory remarks upon the genus; and, in the 
course of a discussion which ensued, Dr. Carte, and the Director of the 
University Museum, made some observations upon the general charac¬ 
ters of the genus Sus. 
The Society then adjourned its meeting to the second Wednesday in 
December.
