He lifted the telescope and focussed it, and his heart came leaping up into his throat just as the figure came leaping into close view through the powerful lense. It was Marion Rose, up by the hydrometer that looked something like a lone beehive perched on a wild slope by itself. She was sitting on a rock with her feet crossed, and she was inspecting her chin in the tiny mirror of her vanity bag.
An instrument much used on the Continent is the Beaumé hydrometer. Ebullition or Boiling of Water, Steam. The atmosphere around us is composed of a mixture of nitrogen and oxygen gases; not a compound of these gases, as water is of hydrogen and oxygen, but a mixture more like sand and water or smoke and air.
As I had neither hydrometer nor thermometer to ascertain the weight and warmth of this water; nor time to procure the proper utensils, to make the preparations, and repeat the experiments necessary to exhibit a complete analysis, I did not pretend to enter upon this process; but contented myself with drinking, bathing, and using the douche, which perfectly answered my expectation, having, in eight days, almost cured an ugly scorbutic tetter, which had for some time deprived me of the use of my right hand.
In every case in which the supersalted water is discharged from the boiler in a continuous stream, a hydrometer or salt gauge of some convenient construction should be applied to the boiler, so that the density of the water may at all times be visible, and immediate notice be given of any interruption of the operation.
There's even a hydrometer for testing the batteries." Rick took a look. As Scotty had said, there were two automobile batteries, their cables running up into the projector. "Simple enough," he commented. "Let's see what's on the film." He opened the film gate gingerly and removed the film from the sprockets. Then, without disengaging the spindles, he put the flashlight behind it and bent close.
Domestic Use of the Hydrometer. The adulteration of milk by water may always be detected by the hydrometer, and in this respect it may be a useful appendage to household utensils. Pure milk has a greater specific gravity than water, being 103, that of water being 100. A very small proportion of water mixed with milk will produce a liquid specifically lighter than water.
He took up an electrometer, a hydrometer, a compass, a thermometer, and a Toricelli barometer, together with bottles of water, in order to collect samples of the air at different heights. In 1785 he made a second ascent, when trigonometrical observations of the height of the balloon were made from the French coast, giving an altitude of 4,800 feet.
