... The vast majority of fossils have been formed under water, and a large proportional number of these—whether the animals were marine, terrestrial, or inhabitants of fresh water—have been formed in sedimentary deposits either of sand, gravel, or other porous material. Now, where such deposits have been afterwards raised into the air for any considerable time—and this has been more or less the case with all deposits which are available for exploration—their fossiliferous contents will have been, as a general rule, dissolved by the percolation ...

... stumps, when I left Port Jackson, showed any symptoms of decay, though some of the trees had been cut down four years. To the different qualities of the wood of Norfolk Island and New South Wales, perhaps the difference of soil may in some measure be traced. That of Norfolk Island is light and porous: it rots and turns into mould in two years. Besides its hardness that of Port Jackson abounds with red corrosive gum, which contributes ...

The same method is used in covering a neteen frame as with the buckram frame. The velvet, if velvet is used, can be glued on, but the material is so porous that it is not very satisfactory.

Then came the chinook, the warm south wind, which eats away the accumulated snow of months in as many days; and the great white banks first grew porous, and then slowly sank away, while the water ran in streams along the streets, or lingered in still pools far under the unbroken crust, waiting to drench the unwary passerby who should venture to set foot upon ...

The ditches were choked with willows and maples to such an extent that they were abandoned only in spots where they asserted themselves, and ...

A small portion of the rainfall and much of the snow water percolates the soil and the porous sandstones which compose the region, and issues in small springs along the edges of the mesas and in the little canyons; but these last only a few months, and they fail in the time of greatest need—in the hot summer days when the ...

Of course, such a change is far more likely to occur to a ring stone than to a turquoise mounted in ...
