He did not, however, enter into the explanation of particular phenomena, as this had been done already by Laplace, but he pointed out to physicists the advantages of the method of Segner and Gay Lussac, afterwards carried out by Quincke, of measuring the dimensions of large drops of mercury on a horizontal or slightly concave surface, and those of large bubbles of air in transparent liquids resting against the under side of a horizontal plate of a substance wetted by the liquid.
In shallower masses a groove was run, and then holes, apparently for wedges, were sunk deeper in the course of it; whether wetted wood was used for the expansive force is not known, but it is probable, as no signs are visible of crushing the granite by hard wedges.
I tell you again that the recollection of the manner in which I saw the queen of France in 1774, and the contrast between that brilliancy, splendour and beauty, with the prostrate homage of a nation to her, and the abominable scene of 1789 which I was describing, did draw tears from me and wetted my paper.
If a number of small enough holes be drilled through a solid substance which is not wetted by the liquid, our knowledge of the phenomena of capillarity shows us that it needs pressure to force the liquid into the holes.
If a thickwalled capillary tube is passed over the platinum tube and its length so adjusted that the liquid rises in it by capillary action just above the level of the tube, the spectrum may be examined directly, and the loss of light due to the passage through the partially wetted surface of the walls of the tube is avoided.
When furs are wetted by rain they should be well shaken and allowed to dry in a current of air without exposure to sun or open fire.
The amalgam is first pressed in wetted canvas or buckskin in order to remove excess of mercury.
Not only the generals in full parade uniforms, with their thin or thick waists drawn in to the utmost, their red necks squeezed into their stiff collars, and wearing scarves and all their decorations, not only the elegant, pomaded officers, but every soldier with his freshly washed and shaven face and his weapons clean and polished to the utmost, and every horse groomed till its coat shone like satin and every hair of its wetted mane lay smooth--felt that no small matter was happening, but an important and solemn affair.
If, however, pairs of metallic disks, made, say, of zinc and copper, are alternated with disks of cloth wetted with a conductor of the second class, such, for instance, as dilute acid or any electrolyte, then the effect of the feeble potential difference between one pair of copper and zinc disks is added to that of the potential difference between the next pair, and thus by a sufficiently long series of pairs any required difference of potential can be accumulated.
Tears wetted her face as men in what looked like black tactical SWAT gear entered the garage.
