The dry land thus depressed must, therefore, have existed, as such, before the Carboniferous epoch in other words, in Devonian times and its terrestrial population may never have been other than such as existed during the Devonian, or some previous epoch, although much higher forms may have been developed elsewhere.
His next engagement was scarcely better starred; for the ship proved so leaky, and frightened them all so heartily during a short passage through the Irish Sea, that the entire crew deserted and remained behind upon the quays of Belfast. Evil days were now coming thick on the Devonian. He could find no berth in Belfast, and had to work a passage to Glasgow on a steamer.
The progress of life is then described as the basis of subdivision into Geological Ages; and the subdivisions of geological time are presented as follows: I. Azoic Time or Age. II. Palaeozoic Time. 1. The Age of Mollusks, or Silurian. 2. The Age of Fishes, or Devonian. 3. The Age of Coal Plants, or Carboniferous. III. Mesozoic Time. 4. The Age of Reptiles. IV. Cenozoic Time. 5. The Age of Mammals.
But then it is urged that, though the Devonian rocks in one part of the world exhibit no fossils, in another they do, while the lower Cambrian rocks nowhere exhibit fossils, and hence no living being could have existed in their epoch.
Analogy seems to me to be rather in favour of, than against, the supposition that while only Ganoid fishes inhabited the fresh waters of our Devonian land, Amphibia and Reptilia, or even higher forms, may have existed, though we have not yet found them.
Cassian beds exhibiting an abundant fauna of mixed mesozoic and palaeozoic types, in rocks of an epoch once supposed to be eminently poor in life; witness, lastly, the incessant disputes as to whether a given stratum shall be reckoned devonian or carboniferous, silurian or devonian, cambrian or silurian.
And I take refuge in one of two alternatives: either they existed in our own area during the Devonian epoch and we have simply not yet found them; or they formed part of the population of some other distributional province of that day, and only entered our area by migration at the end of the Devonian epoch.

Return, indeed, was bitter; Endymion-like, ``my first touch of the earth went nigh to kill'': but it was only to hurry northwards again on the wings of imagination, from dust and heat to the dear mountain air. ``We are only the children who might have been, murmured Lamb's dream babes to him; and for the sake of those dream-journeys, the journeys that might have been, I still hail with a certain affection the call of the engine in the night: even as I love sometimes to turn the enchanted pages of the railway a b c, and pass from one to the other name reminiscent or suggestive of joy and freedom, Devonian maybe, or savouring of Wessex, or bearing me away to some sequestered reach of the quiet Thames.
Its GENERIC characters appeared in other species earlier in the Silurian and continued through the Devonian. Its FAMILY characters, represented in different genera and species, range from the Ordovician to the close of the Paleozoic; while the characters which it shares with all its order, the Zoantharia, began in the Cambrian and are found in living species.
