Take the aprons of the women; give us the safety-lamps, the oil, the brandy; there, ready; slack off!" Burnham had stepped on to the carriage with the men who were going down.

Here, soak the aprons; Ralph, take this; now then, come on!" Up the heading, in single file, they walked swiftly, swinging their safety-lamps in their hands, or holding them against their breasts.

Grace Darling at her oars, Kane in his open boat, Stephenson testing his safety-lamp in the terrible pit,what were the trophies of Miltiades to these?

A conscience quick and sensitive, under the presence of the indwelling Spirit, is like the safety-lamp of the miner, a ready witness and a mysterious guardian against the deathful damps, that unseen, but fatal, cluster around our darkling way.

From this description, and from the fact that the ball is so small that it can be carried in the coat pocket, or, if necessary, in the waistcoat pocket, it will be apparent what a valuable adjunct Mr. Garforth's invention will prove to the safety-lamp.

It would seem from the foregoing remarks that in any existing safety-lamp, where one qualification is increased another is proportionately reduced; so it is doubtful whether all the necessary requirements of sensitiveness, resistance to strong currents, satisfactory light, self-extinction, perfect combustion, etc., can ever be combined in one lamp.

The lamp can be kept in a pure atmosphere while the sample is obtained by the detecter, and at a greater height than the flame in a safety-lamp could be properly distinguished.

the invention of the SAFETY-LAMP for coal mines, which has been generally and successfully adopted throughout Europe.

We could occupy many pages with the interesting details of Sir Humphry Davy's travels in different parts of Europe for scientific purposes, particularly to investigate the causes of volcanic phenomena, to instruct the miners of the coal districts in the application of his safety-lamp, and to examine the state of the Herculaneum manuscripts and to illustrate the remains of the chemical arts of the ancients.

It is not necessary for me more than to advert to his discovery of nitrous oxyde; to his investigation of the action of light on gases; on the nature of heat; to his successful discrimination of proximate vegetable elements; nor to his most scientific, ingenious, and useful invention, the safety-lamp,an invention reasoned out from its principles, with all the accuracy and precision of mathematical deduction.

Thus, beautiful theories were illustrated by inventions of immediate utility, as in the safety-lamp for mitigating the dangers to which miners are exposed in their labours, and the application of a newly-discovered principle in preserving the life of the adventurous mariner.
