THE GEOLOGIST, 
carboniferous deposits ; and I had been assured that the same uncon- 
formability had been detected in the Forest of Dean ; but a careful 
examination, with Dr. Melville, has since convinced me that there ia 
no such imconformability between the Upper Brownstones and the 
overlying masses of conglomerates and red and yellow sandstones in 
this or the Blorenge district. In Ireland the local geologists persist in 
limiting the term Old Eed Sandstone to a series of deposits which there 
most certainly pertain more to the carboniferous group, viz., the 
conglomerates, red sandstones, and yellow and grey sandstones, which 
pass upwards conformably into the Coonahola grits and carboniferous 
slates. The equivalents of our cornstoncs and brownstones of Brecon 
and Monmouth may be studied at Glengariif, at the head of Bantry Bay, 
where the lowest rocks seen are the GlengarifF grits, or upper cornstones, 
overlaid by the Dingle slates or brownstones, and the red sandstones of 
the conglomerate series, with no unconformability. At Muckross, near 
Killarney, the yellow sandstone may be seen, and it overlies the red 
sandstone of the conglomerate series throughout the south of Ireland. 
These yellow sandstone-beds are especially fossiliferous in the Kiltorkau 
district, and have furnished Lycopodiaccous plants, the Spheno2)teris 
Hihcrnica, Anodon Julcesii, the teeth of Dcmlrodus, and a dermal plate 
of Coccosteus. They are, no doubt, the equivalents of the Dura Den 
beds of Scotland, of the beds in the escarpment of the Daren, near 
Crickowell, in Monmouthshire, where Sir 1\. Murchison detected a 
scale of the Holoptychius ; and of the Farlow sandstones in Shropshire, 
where Mr. Baxter, of Worcester, discovered a Ptericththys. Professor 
Haughton exhibited some fossil stems of plants from these deposits at 
Hook Point, County Wexford, which were allied to Stigmaria, and 
curiously entwined by some climbing plant of that ancient epoch. The 
yellow sandstone may also bo seen at Quakertown, near Mallow, en 
mite from Killarney to Dublin ; but the most instructive section from 
the cornstone series of the Old Red (Glengariff grits) to the carboniferous 
slates, inclusive, within the reach of Killarney, is at Bantry Bay. 
" Green Erin " should be " Hospitable Erin." We were strangers 
in the land ; so that the " Come and see me " of a distinguished and noble 
naturalist, who resided in the north of Ireland, sounded right pleasantly 
in our ears ; and truly courteous and kind was the welcome he gave. 
We met at the Droghcda terminus, and our host, who acted as our 
cicerone, knew well the geological formations of the railroad-excavations
