... drapery: it gives the form, but not the stuff. It is the exact reverse with marble. Granulated like a living fibre, yet susceptible of a delicate polish, it can imitate the actual substance of human flesh, with its alternations of opacity and luminousness; it can reproduce, beneath the varied strokes of the chisel, the grain, running now one way, now another, which is given to the porous skin by the close-packed bone and muscle below. Moreover, it is so docile, so soft, yet so resistant, that the iron can ...

... white blotting-paper. All such cases should be very speedily referred to a physician, and the use of needles or other instruments should not be attempted by a layman, lest permanent damage be done to the cornea and opacity result.

These microscopic globules are composed of fatty matter, each surrounded by an envelope of casein, the principal nitrogenous element found in milk. They are lighter than the surrounding liquid, and when the milk remains at rest, they gradually rise to the top and form cream. Casein, ...

The powerful ...

... stationary; and the operations of each would be continual. In the torrid region, nothing but evaporation and heat would take place; no cloud could be formed, because in changing the transparency of the atmosphere to opacity it would be heated immediately by the operation of light, and thus the condensed water would be again evaporated. But this power of the sun would have a termination; and it is these that would begin the region of temperate heat and ...

... bubbles; and the whole plant, instead of rising to the surface of the water as hitherto, hung limp from the fissure where it was placed, and trailed upon the sand. Coincidently, (was it consequently?) a greenish tinge pervaded the water, speedily increasing in depth and opacity. In five days, no object could be discerned six inches from the glass, and my beautiful Aquarium was transformed to an ...

... universal. All the others are partial and limited. All the others, even the newly discovered cathode rays, are subject to obstruction by certain forms of matter; that is, to them certain forms of matter are opaque. But gravitation knows no opacity in the universe. No atom of matter is exempt from its sway. It streams through all obstructive media as though such media did not exist. It would appear that heat, light, electricity, sound, the cathode rays, and all other ...

He dived, swam about beneath, groping in the frightful opacity, but still in vain. Then down through the water came a shout, and he shot to the surface—to see only something white vanish. But the recoil of the torrent from below caught her, and just as he was diving again, brought her up almost within arm's-length of him. He darted to her, clasped ...

... group of flying particles, each one invisible, obstructs light singularly little, even when they are close together, as one can tell by the transparency of showers and snowstorms.

It gives a slight opacity to the culture fluids, and when magnified two thousand diameters appears as a minute spiral or round or stellate organism having a variety of forms. Its size is such that it passes the coarse, but is held back by the finer, filters and it is possible that this does not belong to the same class ...
