... the old mode of burial. In the tumuli of the Bronze age, on the other hand, where the date can be determined with the aid of the ornaments and trinkets scatered about, the ustion was more complete; the bones are friable and porous, crumbling into dust when touched, and there is nothing to indicate that inhumation and cremation ...

... soft, is fairly tough, as its waxy luster might make one suppose, and in addition, being an opaque stone, slight dulling or scratching hardly lessens its beauty. It may therefore be used in ring mountings. However, it should be suggested that most turquoise is sufficiently porous to absorb grease, oil, or other liquids, and its color is frequently ruined thereby. Of course, such a change is far more likely to occur to a ring stone than to a turquoise mounted in some ...

... is too hot; open the damper ten minutes. Your bread, after it is in the tins, will rise much more quickly than the first time. Let it get light, but not too light—twice its bulk is a good rule; but if it is light before your oven is ready, and thus in danger of getting too porous, work it down with your hand, it will not harm it, although it is better so to manage that the oven waits for the bread rather than the bread for the oven. A small loaf—and by all means make them small until you have gained experience—will not take more than three quarters of an hour to bake; ...

... coal, that which is broken or screened, is best for grates, and the nut-coal, for small stoves. Three tons are sufficient, in the Middle States, and four tons in the Northern, to keep one fire through the Winter. That which is bright, hard, and clean, is best; and that which is soft, porous, and covered with damp dust, is poor. It will be well to provide two barrels of charcoal, for kindling, to every ton of anthracite coal. Grates, for bituminous coal, should have a flue nearly as deep as the grate; and the bars should be round, and not close together. ...

... all Italy must have been ransacked in old times for garden stone-work of exceptional beauty; and these treasures have been put together by some master-hand. Even the formal borders of the walks are of old porous stone, which takes the weather-staining so beautifully, and are carved in endless variety. Now that the gardens have been so long neglected or left in abeyance, the green staining has become perfect. Though the stone-work is itself intact, it has all the picturesque effect of the wear ...

To obtain variations from light to dark in each pigment Jackson scraped down the blocks with a knife; he thus lowered the surfaces slightly and created porous textures which would introduce the white paper or the underlying color. Examination of the prints clearly shows granular textures in the light areas. Scraping to lighten impressions was a common procedure in black-and-white printmaking, and was described ...

There, in a little shop near the church—a dark and cool place, the first shade we had entered for many hours—we drank without ever growing less thirsty. We felt like cinders, so hot, so porous, that the liquid seemed not only to find its way into the legitimate receptacle but to be obliged to percolate, by some occult process of capillarity, the remotest regions of the body. As time went on, the inhabitants dropped in ...

This work was done by the monks themselves, who thought, as Professor Willis suggests, that they could do it better than common workmen. Their work is made of a light and porous kind of stone, treated with plaster on the under-side, and it was rendered necessary by the previous roof, which was of wood, having been destroyed by fire in 1190. Of this fire the piers certainly show the ...

... the reasoning exactly as it occurred to my mind. Its result will be anticipated by many present. All bodies possess the power of condensing, in a greater or less degree, gases and vapours upon their surfaces, and when the condensing body is very porous, or in a fine state of division, the force of condensation may produce very remarkable effects. Thus, a clean piece of platinum-foil placed in a mixture of oxygen and hydrogen so squeezes the gases together as to cause them to combine; and if the experiment be made with care, the heat ...

Therefore, whenever a porous earth or a fissured rock crops out to the light of day, there is, in ignorance of all other facts, some chance of a spring being discovered in the lowest part of the outcrop. A favourable condition for the existence of a large and permanent ...

Burnley bade Hope observe that the water was trickling through in places, a drop at a time; it could not penetrate the coaly veins, nor the streaks of clay, but it oozed through the porous strata, certain strips of blackish earth in particular, and it trickled down, a drop at a time. Hope looked at this feature with anxiety, for he was a man of science, and knew by the fate of banked reservoirs, great and small, the strange explosive power of a little water driven through strata by ...

The ice we took up proved to be none of the best, being chiefly composed of frozen snow; on which account it was porous, and had imbibed a good deal of salt water; but this drained off, after lying a while on deck, and the water then yielded was fresh. We continued to stretch to the east, with a piercing cold northerly wind, attended with a thick fog, snow, and sleet, that decorated ...

As I walked along I observed that the island was composed of white porous pumice stone, without the least symptoms of vegetation; not even a piece of moss could I discover—nothing but the bare pumice stone, with thousands of beautiful green lizards, about ten inches long, playing about in every part.

As each wave lifted and retreated, leaving the porous wall dripping like a sponge, it disturbed countless crabs, rock scorpions and creeping, leech-like things that ran blindly into the holes in the limestone; and, at the water-line, the sea-weed, licking hungrily at the wall, rose and fell, the great ...

In a cross section of Oak or Chestnut the wood is first very open and porous and then close. This is owing to the presence of ducts in the wood formed in the spring. In other woods there are no ducts, or they are evenly distributed, but the transition from the close autumn wood, consisting of smaller and more closely packed cells, ...

There were places in the upper reaches among the Swabian forests, when yet the first whispers of its destiny had not reached it, where it elected to disappear through holes in the ground, to appear again on the other side of the porous limestone hills and start a new river with another name; leaving, too, so little water in its own bed that we had to climb out and wade and push the canoe ...

Red streams had once flowed out of them. A few times we passed near fresh cracks in the ...

The tottering hovel, built of porous stone in rough blocks, was coated with yellow plaster much cracked, and looked ready to fall before a gust of wind.

In walking over this extensive surface, there was occasionally a hollow, drum-like sound beneath the feet, denoting subterranean cavities in the porous and soluble strata beneath the harder upper stratum. It was a natural consequence that a substratum impervious to water should form a bed at a certain level to retain the drainage: by tapping this bed at any point, the water would be discovered; but by piercing the surface ...

Thus the Temple of Zeus at Olympia, one of the two most important religious centers in the Greek world, was built of local poros. The same ...
