Meanwhile Ahab half smothered in the foam of the whale's insolent tail, and too much of a cripple to swim,--though he could still keep afloat, even in the heart of such a whirlpool as that; helpless Ahab's head was seen, like a tossed bubble which the least chance shock might burst.
They are flattened oval in form, circling with gliding motion over the surface film of the water, and occasionally diving, when they carry down with them a bubble of air.
The fire hissed in the waves; the same instant the ship shot by the bubble the sinking pipe made.
If to increase the area of the surface requires the expenditure or or of work, the surface must resist extension, and if the bubble in contracting can do work, the surface must tend to contract.
That the bubble has energy may be shown by leaving the end of the tube open.
The warm bubble bath was relaxing.
It was further thought that the occupation by Great Britain of the country beyond the Orange River had been a bubble and a farce, in which the Cape colonists were all interested; for that it was to them a great gaming table and out of the reach of the police....
Leidenfrost (De aquae communis nonnullis qualitatibus tractatus, Duisburg) showed that a soap-bubble tends to contract, so that if the tube with which it was blown is left open the bubble will diminish in size and will expel through the tube the air which it contains.
It can be restored by moving the bracket till the bubble of the spirit-level is central, and then clamping it.
If now the telescope be directed on the target and this level be brought to the centre of its run, the angle of sight can be read - if afterwards any range ordered is put on the sight and the gun truly layed, this bubble will be found in the centre of its run - so that if thereafter the target becomes obscured the gun can be relayed by elevating till the bubble is in the centre of its run, or at a completely concealed target the angle of sight can, if the range and difference of level are known or can be measured from somewhere near the gun, be put on by means of the micrometer screw, and the gun subsequently layed by putting the range in yards or degrees on the sight drum and elevating or depressing till the bubble is central.
