290 Mr. Weaver on the Structure of the South of Ireland^ 
of limestone, with their bounding schistose and conglomerated 
rocks, which in their range traverse Cork harbour, and which 
according to my observations are all in parallel position, with 
a dip to the south ; but Mr. Griffith represents them as forming 
successive troughs, with corresponding anticlinal and synclinal 
dips, of which I certainly have no knowledge. In one essen- 
tial point, however, we are agreed, namely, that these parallel 
bands of limestone show, wherever exposed, an interstratifica- 
tion with the adjacent clayslate, both rocks exhibiting in general 
the same organic remains; which are also contained in the clay- 
slate still further south, on the north side of Ringabella inlet, 
and again on the same parallel to the west, adjacent to the 
road leading from Cork to Brandon. But in the clayslate 
and sandstone subordinate to it are found also vegetable re- 
mains, showing a further analogy to similar rocks north of the 
Bride, to those north of the Blackwater, and at Dunmore 
head in Kerry. Mr. Griffith has given us a list of transition 
fossils which he had collected at Ferriter’s cove; and another 
list of those he had obtained from the limestone and clayslate 
of Cork harbour, at Rostellan, Rinniskiddy, &c. Of the lat- 
ter Mr. Sowerby has pronounced some species to be the same 
as occur in the carboniferous limestone, and others to resem- 
ble such as are found in the older stratified rocks of Devon- 
shire; and it might be added also such as occur also in Ferri- 
ter’s cove and in the Silurian system, e. g., Lept(B7ia (Producta) 
lata, Leptana depressa. I may also add, as a further analogy, 
that in the older stratified rocks of Devon and Cornwall, ve- 
getable remains are likewise met with ; e. g., in Devon as ob- 
served by Major Harding, the Rev. D. Williams, Professor 
Sedgwick, and Mr. Murchison ; and in Cornwall by Pro- 
fessor Sedgwick, as noticed by Mr. Ansted in his paper on 
Endosiphonites * (the Clymenia of Count Munster.) 
Every addition to our knowledge is valuable, and I trust 
Mr. Griffith will continue to employ hands in the south of 
Ireland in collecting fossils, for which he possesses so many 
opportunities, 
I have now to advert to Mr. Griffith’s section in the Dingle 
peninsula, in the west of Kerry, which in no part exactly ac- 
cords with my observations. In this section the vertical 
scale is to the horizontal scale as five to one. But the por- 
tion which more immediately claims attention is that which 
extends from the summit of the old red sandstone of the 
Slieve Meesh range f to the carboniferous limestone in the 
Cambridge Phil. Trans., vol. vi. 1838. 
t Called Cahirconree by Mr. Griffith, but which denomination I conceive 
to apply strictly to the mountain range stretching to the west o f Bartrigoun,
