 ... indicator; the useful work, by a Prony brake; the temperature of the water, by a standard thermometer; and that of the escaping gases, by a pyrometer. The gas itself was analyzed; and its heating power calculated, from its composition, as 617.5[theta]. Its specific gravity was .464; and the volume of air was about seven times that of the gas used (or one-eighth of the mixture), and was only 111/2 per cent. by weight more than was needed for perfect combustion. The results ...

The wooden half-model, he said, was a one-ninety-sixth, instead of the usual one-forty-eighth; yet, even so, it was 5 ft. 7- 1/2 ins. long, as much broad, and 1 ft. 3/4 in. high. ...

... porphyroids are conglomerate, but the majority are true porphyries, having a homogeneous base. Dr. T. Sterry Hunt calls them porphyroid trachytes. They have a black, rarely reddish, vitreous, or impalpable base, approaching obsidian, with a specific gravity of 2.59 in pure specimens, and holding crystals or crystalline grains of glassy feldspar, and sometimes of pyroxene and hematite. They differ from the Old World porphyries in containing no quartz, and seldom mica.[63] D'Orbigny considers the porphyries of the Andes to have ...

While, if any one were to propose for investigation the common properties of all things which are of the same color, the same shape, or the same specific gravity, the absurdity would be palpable.

The experiments with absolute alcohol and with alcohol containing varying amounts of water showed no differences in the results, and hence it is now our custom to obtain the highest grade commercial alcohol, determine the specific gravity accurately, and burn this material. We use the Squibb pyknometer[28] and thereby can determine the specific gravity of the alcohol to the fifth or sixth decimal place with a high degree of accuracy. Using the alcoholometric tables of Squibb[29] ...

The scattered elements of a denser kind, by means of their attraction, gather from a sphere around them all the matter of less specific gravity; again, these elements themselves, together with the material which they have united with them, collect in those points where the particles of a still denser kind are found; these in like manner join still denser particles, and so on.

Its height is remarkably uniform, ranging from sixty to one hundred feet above the water-level. When allowance has been made for average specific gravity, its average total thickness should approximate to six hundred feet. From east to west the formation was proved to be as much as two hundred miles, with one hundred and eighty miles between its northern and ...

Now, to assert that this, ...

True anthracite is hard, compact, lustrous and sometimes iridescent, and is characterized by few joints and clefts. Its specific gravity varies from 1.4 to 1.8. In burning, it kindles slowly and with difficulty, is hard to keep alight, and burns with a short, almost colorless ...

The original tissue is colourless; but according to the nature of the secretions deposited in it, the heartwood is either of a deeper colour, sometimes party-coloured, or at least of a much greater specific gravity than the sapwood. The removal of the juices by any solvent restores the wood to its primitive hue, and renders it again light. The difference of weight of a cubic foot of wood depends not merely on the different quantity of vegetable ...

At last Setoc began to consider Zadig as a sage, and preferred ...

We venture to incline to the opinion that not only the Gulf Stream, but all the constant currents of the sea are due chiefly to difference of temperature and saltness.
