xiii. oldal - Studies serve for delight, for ornament, and for ability. Their chief use for delight, is in privateness and retiring; for ornament, is in discourse; and for ability, is in the judgment and disposition of business...
178. oldal - There was a violent effervescence at the upper surface ; at the lower, or negative surface, there was no liberation of elastic fluid ; but small globules having a high metallic lustre, and being precisely similar in visible characters to quicksilver, appeared, some of which burnt with explosion and bright flame, as soon as they were formed, and others remained, and were merely tarnished, and finally covered by a white film which formed on their surfaces.
178. oldal - By this arrangement some brilliant phenomena were produced. The potash appeared a conductor in a high degree, and as long as the communication was preserved, a most intense light was exhibited at the negative wire, and a column of flame, which seemed to be owing to the development of combustible matter, arose from the point of contact.
132. oldal - In the use of this apparatus, the bottle is first filled with the liquid employed, which is best prepared by boiling a mixture of quick lime and sulphur with water, filtering the solution, and agitating it for some time in a bottle half filled with common air. The tube, filled with the gas under examination, or with common air, if that be the subject of the experiment, is next put into its place, and, on inverting the instrument, the gas ascends into the bottle, where it is brought extensively into...
97. oldal - The fixation of calorie in water, by its conversion into steam, may lie shown by the following experiments: — 1. Let a pound of water at 212°, and eight pounds of iron filings at 300", be suddenly mixed together. A large quantity of vapour will be instantly generated ; and the temperature of the mixture will be only 212° ; but that of the vapour produced is also not more than 212...
111. oldal - In this space, the vessel c may move freely up and down. The interval is filled with water as high as the top of the inner cylinder. The cup, or rim, at the top of the outer vessel, is to prevent the water from overflowing, when the vessel c is forcibly pressed down, in which situation it is placed, whenever gas is about to be collected. The gas enters from the vessel in which it is produced, by the communicating pipe...
364. oldal - With regard to the method of laying down the divisions of this scale, those who are accustomed to the use of other sliding rules, and are practically acquainted with their properties, will recognise upon the slider itself, the common Gunter's line of numbers, (as it is called) and will be satisfied, that the results which it gives are the same that would be obtained by arithmetical computation. Those who are acquainted with the doctrine of ratios, and with the use of logarithms as measures of ratios,...
79. oldal - Two glass tubes of unequal lengths, each terminating in a hollow ball, and having their bores somewhat widened at the other ends, a small portion of sulphuric acid tinged with carmine being introduced into the ball of the longer tube, are joined together by the...
374. oldal - The power of the calorimotor is much increased by having the communication between the different sheets formed by very large strips or masses of metal. Observing this, I rendered the sheets of copper shorter by half an inch, for a distance of four inches of their edges, where the communication was to be made between the zinc sheets ; and, vice versa, the zinc was made in the same way shorter than the copper sheets where these were to communicate with each other. The edges of the shortened sheets...
