above the millstone-grit. 
Florence Court, the seat of the Earl of Enniskillen, is situated on the 
Calp series, which we observed was cut into by several water-courses 
and drains. The mansion is handsome, and surrounded by noble trees ; 
one avenue of the silver fir alone commanding the attention of the 
naturalist. The museum is an octagon room lighted from the roof, and 
contains, with the exception perhaps of Sir P. Egerton's, the finest 
private collection of fossil-fishes in Great Britain. On a platform in 
the centre there towers the perfect skeleton of the gigantic elk, 
Mcgaceroa Hilernicus, and the walls are surrounded by glass-cases 
filled with the choicest fossils. We actually revelled among the 
remains of fossil-fish, from the pigmy teeth and spines of the Upper 
Silurian, to the stony yet fresh-looking specimens of the Tertiaries. But 
to none did we pay such especial attention as to the Ichthyolites of the 
Old Ked Sandstone, very many of which were obtained from localities 
rendered classic by the pen of the lamented Hugh Miller. There were 
the stonyrelics of those long-dead organisms, with their delicate shadings, 
and " the dingy deep gray of the stone converted into light-buff, 
and on this ground, not verj"- different from that which the limner would 
choose for a drawing in chalk, the fossils stand out in delicate azure, 
and varying in tint from a deep ultramarine to a light verditure." 
While, as we mused on the Coccosteus and Dipterus, the Cephalaspis 
and Glyptolepis, and those bituminous schists of Caithness, with " the 
colour as intensely black as that of the sealing-wax of a funeral letter, 
and turned over the pages of the work that describes these wonders in 
words so vivid and so true, we thought that 'Devonian' seemed 
scarcely the term to apply to those strata that have furnished those 
organisms and their history ; while right glad are we to find that the 
chief of Siluria, in his new edition of his well-known work, still holds 
well and firmly, as regards the Scotch and Herefordshire districts, to 
the good old title of ' Old Eed Sandstone.' " 
The Calp of this district extends from Lough Erne to Bandoran, on 
the south-east coast of Donegal Bay ; and in Belmore, near Enniskillen, 
and Ben Naglin, near Florence Court, it is surmounted by 600 feet of 
upper carboniferous limestone. There is an impure limestone of the 
Calp scries, which in this district is highly fossiliferous and full of 
encrinital heads and stems, with large and perfect Product!, whcih benig
