(In The American mercury magazine, Dec. 1927)

Then came a piercing burst of greenish-blue light from a long tube which looked like a curious mercury vapor lamp.

[explosive substances] gunpowder, dynamite, gun cotton, nitroglycerine, nitrocellulose, plastic explosive, plastique, TNT, cordite, trinitrotoluene, picric acid, picrates, mercury fulminate (arms) 727. whack, wham, pow.

At its base the cylinder is prolonged into two little rods, h and h', which plunge into two mercury cups, G and G'.

For four successive days, near the summit of the pass on the western slope, mercury froze at noon.

But the Dead Sea was living up to its reputation, quiet, inert, like a mercury mirror for the starsa brooding place of silence.

" A tall regulator-clock, with its mercury pendulum, ticked upon the wall; the noise of the heavy rumbling in the streets was softened into a low monotone, and now and then a bit of coal rattled upon the fender.

The new mercury pump constructed by Messrs. Greisser and Friedrichs, at Stutzerbach, is remarkable for simplicity of construction and for the ease with which it is manipulated, and also because it enables us to arrive at a perfect vacuum.

The higher the level of the sea, the less becomes the sum of the resistances of the rheostat, since the column of mercury puts in short circuit all the divisions of the rheostat, whose contacts are comprised in the height of the column.

[5708] "nullis ille movetur Fletibus, aut illas voces tractabilis audit;" Let thy Mercury-reason rule thee against all allurements, seeming delights, pleasing inward or outward provocations.

The mercury reservoir having descended, the bulb empties itself, and then the tap is turned on again, in order to establish communication with the exhausting tube.

The temperature of the blood is about 97 or 98 degrees, and if the temperature of the air be below the temperature of the blood, of course when the hand is applied to the thermometer the mercury rises.

A misplaced word might send her away as oblivious of him as a globule of mercury rolling free from the grasp.

The fault, as I had not and have not the smallest doubt, depends in some way on the crystallization of the mercury silvering.

" It was a solid phalanx of men which had collected around the moveless bodies as swiftly as mercury sinks through water.

The parts are then washed in a perchloride of mercury solution, covered with a mixture of powdered iodoform and boracic acid, over which a pledget of carbolized tow is placed, and then a bandage over the whole.

In order to obtain as great a deflection of the balance by the method suggested by Prof. Mayer, each of the mercury spheres must exert the same attraction as our lead block.

"And in hot weather the mercury swells, puffs itself out and creeps up inside the little glass tube.

Defiance, deference, contempt, and pity all blended in his mien, but over all was an I-am-the-one-you-are-the-many atmosphere of confidence that turned my spinal column into a mercury tube.

The water does not freeze until the thermometric mercury tumbles down to eighteen degrees above zero, or fourteen below the ordinary freezing point.

The chlorine liberated at the anode is employed in the manufacture of bleaching-salt, and the sodium is liberated at a mercury cathode, with which it at once enters into combination as an alloy.

But Marconi is experimenting to reduce the noise, and the use of the mercury vapour invented by Peter Cooper Hewitt will do much to increase the rapidity in sending.

The inventor has heretofore made mercury column gauges for gunpowder pressures, which were too large for direct attachment to guns, but were connected with special powder chambers to test the pressure, etc., of confined explosives.

9. Q.Is the vacuum in the condenser a perfect vacuum? A.Not quite perfect; for the cold water entering for the purpose of condensation is heated by the steam, and emits a vapor of a tension represented by about three inches of mercury; that is, when the common barometer stands at 30 inches, a barometer with the space above the mercury communicating with the condenser, will stand at about 27 inches.
