In the spectacles of gladiators, sometimes, when the sun was violently hot, he would order the curtains, which covered the amphitheatre, to be drawn aside , and forbad any person to be let out; withdrawing at the same time the usual apparatus for the entertainment, and presenting wild beasts almost pined to death, the most sorry gladiators, decrepit with age, and fit only to work the machinery, and decent house-keepers, who were remarkable for some bodily infirmity.
The mirror as it moves throws a beam of light upon a scale and the indications are read by the spot of light. Most novel of all the apparatus of this measuring kind is the odoroscope, which is like the tasimeter described in an earlier chapter, except that a strip of gelatine takes the place of hard rubber, as the sensitive member.
We must avoid, however, falling into the common mistake of holding in little esteem those parts of Faraday's work that did not immediately result either in the production of practical apparatus, or in valuable applications in the arts and sciences, or those which have not even yet proved fruitful.
She came back, followed by a boy carrying a portable apparatus for cooking. "All that Philip wants, and all that we want," she explained, "we can provide for ourselves. Give me a morsel of paper to write on." Unhooking the little pencil attached to her watch-chain, she paused and looked toward the door. "Somebody listening," she whispered. "Let them listen."
With an apparatus like the one here figured, and in which the filtering tube is eight inches in length by about one inch in diameter, about four and a half gallons of water per day may be obtained when the pressure is two atmospheres the mean pressure in Mr. Pasteur's laboratory, where my experiments were made. Naturally, the discharge is greater or less according to the pressure.
One investigator, who strongly disapproves of the trailing aerial, has carried out experiments with a network of wires laid upon and attached to the surface of the aeroplane's wings. But the trailing wire is generally preferred, and certainly up to the present has proved more satisfactory. The greatest obstacle, however, is the necessary apparatus.
Terry came running to him, flushed with her excitement, and shoved the glasses up to his eyes. Temple dodged, fussed with the focussing apparatus, lowered the glasses, and blinked down the road. "It's just a wagon, ain't it?" he demanded. "Looks like " Again she snatched the binoculars. "A lot of men are standing up," she announced.
There was comparatively little difficulty in ferreting out the "vermin" to use the expression of a Walloon historian of that age so that it was only necessary to maintain in good working order the apparatus for destroying the noxious creatures when unearthed.
Plans were made for a line between New York and Philadelphia, and to arouse interest and secure capital the apparatus was exhibited in New York City at a charge of twenty-five cents a head.
In the present state of affairs, my dear general, I hope you will come yourself to Virginia, and that, if the French army moves this way, I will have, at least, the satisfaction of beholding you myself at the head of the combined armies. Lord Cornwallis must be attacked with pretty great apparatus.
