When they attain to the diameter of about six inches, they uniformly die, and this they will no doubt continue to do until the decay of leaves and wood on the surface, and the decomposition of the subjacent rock, shall have formed, perhaps hundreds of years hence, a stratum of soil thick enough to support a full-grown forest.
The soundings, which showed a rapid rise in the bottom as the Fram changed her position southward along the Barrier, are also a clear sign that land is close at hand. Finally, the formations of the Barrier appear to be the best proof. It could not rise to 1,100 feet which we measured as the rise from Framheim to a point about thirty-one miles to the south without subjacent land.
Its view of the subjacent plain overlooks the city of Paris by a distance of twenty miles. The fountains and jets d'eau are entitled to special notice, although in extent and variety they are far exceeded by those of Versailles.
At p. 460 of his Manual of Elementary Geology, Sir Charles Lyell gives a list in illustration of this. It appears that in 1709, fishes were not known lower than the Permian system. In 1793 they were found in the subjacent Carboniferous system; in 1828 in the Devonian; in 1840 in the Upper Silurian.
In the neighbourhood of volcanic vents, we frequently observe accumulations of angular fragments of rocks formed during eruptions by the explosive action of steam, which shatters the subjacent stony formations, and hurls them up into the air. They then fall in showers around the cone or crater, or may be spread for some distance over the surrounding country.
According to the theory of Pangenesis, it is necessary to assume that all the gemmules of this anomalous formation, and therefore the mother-gemmule of the cell, and the daughter-gemmules of the special epidermic tissue, and of the very singular subjacent tissue of the endothecium, have been perpetuated, and transmitted from parent to offspring in a dormant state, and through a number of generations, such as startles the imagination, and leads it to refuse its consent to the theory of Pangenesis, however seductive it may be."
The diameter of these near the root is about one foot; but I measured one myself, in 1866, which was 3 1/2 feet in diameter, said by the quarrymen to be unusually large. Root-shaped cavities were observed by Professor Henslow to descend from the bottom of the dirt-bed into the subjacent fresh-water stone, which, though now solid, must have been in a soft and penetrable state when the trees grew.
This required a daily puncture for the evacuation of subjacent fluid, for six days; it then remained adherent, and in about a fortnight it separated leaving the ulcerated surface healed. This patient was not at all confined. Mr. S. aged 30, had a sore two inches in length in the groin, the remains of a phagedenic ulcer.
But, as it is known, the filtering beds of the basins in the water conduits are soon covered with a thick coating of confervae, and the Limnophysalis hyalina then extends from the deepest portions of the filtering beds into the filtered water subjacent.
On the mountains of North Wales and on the Alps, worms, as I have been informed, are in most places rare; and this may perhaps be due to the close proximity of the subjacent rocks, into which worms cannot burrow during the winter so as to escape being frozen. Dr. McIntosh, however, found worm-castings at a height of 1500 feet on Schiehallion in Scotland.
