The surface of this lava lay in wave-like corrugations, like the hide of a rhinoceros, showing that it was or had been semi-fluid. In the centre rose a great, black, rounded cone, like the cupola of an immense blast furnace.
And they play golf in a large, expensive, thorough way because it's the thing to do.... Now here in Essex we're as lax as the eighteenth century. We hunt in any old clothes. Our soil is a rich succulent clay; it becomes semi-fluid in winter when we go about in waders shooting duck. All our fingerposts have been twisted round by facetious men years ago. And we pool our breeds of hens and pigs.
However this may be, rain, even when not very heavy, if long continued, renders recently-ejected castings semi-fluid; and on level ground they then spread out into thin, circular, flat discs, exactly as would so much honey or very soft mortar, with all traces of their vermiform structure lost.
The opinion which seems to be most in favour among learned men and that which I myself hold firmly is, the theory of the Scottish Professor Forbes, namely, that a glacier is a semi-fluid body, it is largely impregnated throughout its extent with water, its particles move round and past each other in other words, it flows in precisely the same manner as water, the only difference being that it is not quite so fluid; it is sluggish in its flow, but it certainly models itself to the ground over which it is forced by its own gravity, and it is only rent or broken into fragments when it is compelled to turn sharp angles, or to pass over steep convex slopes.
Death by drowning occurs when breathing is arrested by watery or semi-fluid substances blood, urine, etc. The fluid acts mechanically by entering the air-cells of the lung and preventing the due oxidation of the blood. Froth like that of soap-suds in the trachea is an indication of a vital act, and must not be mistaken for the tenacious mucus of bronchitis.
Some species grow only in contact with air, others need no more oxygen than they can obtain in the fluid or semi-fluid which they inhabit. Importance of Bacteria in Nature. We might well ask why the myriads of bacteria do not devastate the earth with their marvelous rapidity of propagation.
The yeast plant is a mere sac, or "cell," containing a semi-fluid matter, and Schwann's microscopic analysis resolved all living organisms, in the long run, into an aggregation of such sacs or cells, variously modified; and tended to show, that all, whatever their ultimate complication, begin their existence in the condition of such simple cells.
The liver, the lung, the spleen are attacked to better purpose, without, however, getting beyond the state of a semi-fluid jam, which easily mixes with water and even appears to dissolve in it. The brains do not liquefy either: they simply melt into a thin gruel. On the other hand, fatty substances, such as beef suet, lard and butter, do not undergo any appreciable change.
They usually project from the surface of the bone, and may attain an enormous size; sometimes they grow in the interior of a bone, the so-called enchondroma. The hyaline cartilage composing the tumour frequently undergoes myxomatous degeneration, resulting in the formation of a glairy, semi-fluid jelly, and if this change takes place throughout the tumour it comes to resemble a cyst.
