 ... of the lead was 9 lbs., and the tubs, being lashed longitudinally together, rolled in a tideway unfettered, being anchored by the usual lines and heavy stones. The leads sank the casks to the bottom in 2-1/2 fathoms of water, but at that depth they in specific gravity so nearly approximated to their equal bulk of fluid displaced that they could scarcely be felt on the finger. The leads were cast in moulds to the size required, and could be repeatedly used for the same purpose, and it was thought that ...

The mixture had better be allowed to stand several days before filling the tank; for thus the impurities of the chemicals will settle, and the clear liquor can be decanted off. The specific gravity should then be tested with 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 ...

... different from that of natural crystallized CaSO4, known to mineralogists under the name of anhydrite. By the influence of a high temperature it appears probable that a molecular change is gradually induced with production of a crystalline structure, and probably an increase of specific gravity, resulting in the artificial reproduction of the mineral anhydrite. No determination appears to have been published of the specific gravity of plaster prepared by complete baking at a low temperature. The theory is, however, confirmed by the results obtained by workers on the subject ...

When now I presume: water has a body, it has a definite density, it has consistency, weight, etc., I will also presume that I may go on walking over its surface just as over the surface of the earth,—and that, simply because I am ignorant of its fluidity and its specific gravity.
