F. 
Domanik Schist. 
The reader will find that in the text, p. 413, we have considered the Domanik as the equivalent of the 
Wissenbach schists, and therefore, according to the reasoning formerly employed (see Geol. Trans, vol. vi. 
p. 253), belonging rather to the Uppermost Silurian than the Lowest Devonian. Since, however, the 
chapter on the Timan Range was written, the fossils of the Domanik having been carefully examined 
by Count Keyserling, he finds that its Goniatites are similar to those of Brilon in Westphalia, and Schu- 
belhammer in Franconia. It must, therefore, be considered Lower Devonian, and we have placed it 
accordingly in the Table of Superposition attached to the Map, PI. VI. 
G. 
Igneous Origin of Magnetic Iron Ore. 
In the text, p. 413, we have dwelt at some length on this point, and it may further be curious for 
geologists to speculate on the possible application of the same view to many deep and unfathomed 
masses of iron in other countries. The broad and deep masses of red and often intensely crystalline 
hematite near Ulverstone in Cumberland, which fill chasms in the carboniferous limestone, are now usually 
looked upon as aqueous deposits. But may the striking vein of pure brown hematite charged with man- 
ganese, -which at Lostwithiel in Cornwall seems to rise up through slaty rocks (Devonian) and envelopes 
fragments of them in its matrix, be considered an eruptive dyke like that to which we have alluded at 
Blagodat ? In throwing out this query, we do not say that the English case ought not to be separately 
considered ; for whilst it is possible that it may be explained in a somewhat similar manner to those of 
the Ural, it may, we admit, have resulted from a long-continued humid process — always, however, de- 
pendent on subterranean agency and internal heat and gas — through which the fluid was impregnated 
with metallic or other elements, that have either been crystallized or deposited in amorphous forms
