Half-way the length of the sluice-boxes the finest gravel, yellow and black sand, dropped through perforated sheet-iron grizzles into the "undercurrents" while the rocks and boulders rushed on through the sluice-boxes to the river.

The roads were beginning to thaw out, and the country was black and dirty looking. Here and there on the dark mud, grey snow crusts lingered, perforated like honeycomb, with wet weedstalks sticking up through them. As the wagon creaked over the high ground just above Frankfort, Claude noticed a brilliant new flag flying from the schoolhouse cupola.

The chair is like an ordinary library chair, with solid back and sides, sculptured out of a single block, and perforated in the seat with a circular aperture. Rosso antico is not what might strictly be called a beautiful marble. Its colour is dusky and opaque, resembling that of a bullock's liver, marked with numerous black reticulations, so minute and faint as to be hardly visible.

"It does not matter whether the patient suffers from catarrhal appendicitis, with or without a foreign body in the appendix, or whether the appendix be gangrenous or perforated, he will almost invariably recover if from the beginning of the disease absolutely no food is given by mouth."

Reaching the Caves, he laid the matter hurriedly before the Chief, and within five minutes they were leading a dozen warriors up the trail. Besides their customary weapons, both Grôm and the Chief carried fire-sticks, tubes of thick, green bark, tied round with a raw hide, filled with smouldering punk, and perforated with a number of holes toward the upper end.

It was a perilous undertaking for him, for the Cossacks were still riding about, and he showed me with pride the place where a stray bullet had perforated his knapsack during the search. He revived me, gave me first aid, and succeeded with great difficulty in helping me out of the trench. For more than three hours we stumbled on in the night, trying to find our lines again.

It seemed to be a little black disk about as big as a watch, with a number of perforated holes in one face. Carelessly he tossed it into the top drawer of the chest under some old rubbish, shut the drawer tight and ran a flexible wire out of the back of the chest.

Their handles vary in size and shape, are usually hollow, and sometimes are perforated at the end. In certain specimens the extremity is prolonged into a pointed, recurved tip, and sometimes is coiled in a spiral. A groove in the upper surface of one example is an unusual variation, and a right-angle bend of the tip is a unique feature of another specimen.

The heavier particles of dirt, that would settle in time, take the outside, leaving perfectly clean water in the middle. A perpendicular perforated pipe, with a faucet below, drains off all the clear water and leaves all the mud.

But Galen gave a very different explanation. He believed that impure "animal spirits" were carried to the cavities of the brain by the arteries in the neck and from there were sifted out through these perforated bones, and so expelled from the body.
