"Duct" Quotes from Famous Books



... These both end in a point, which, however, is not toothed and does not project as far as the final rasp. They also unite to form a groove, which fits into the groove of the other two, the whole constituting a complete channel or duct. Moreover, the two shorter pieces, considered together, can move, lengthwise, in the groove that receives them; they can also move one over the other, always lengthwise, so much so that, on the slide of the microscope, their ...

... houses, the preference was given to the open fire-place. The hot-air furnace deriving a supply of pure air from out of doors was, when properly constructed, a very satisfactory method of heating, but in city houses the mistake was often made of carrying the cold air duct of the furnace to the front of the house, where it was exposed to the dust of the streets. It should be taken from the rear end of the house, and carried some distance above the surface of the yard. It was an excellent expedient to insert in the cold air duct a wire screen to hold a layer ...

... the membranes of nictitans are very much the same. A partial or complete closure of the eye, and a watery discharge due to overstimulation of the lachrymal glands, the fluid being secreted so abundantly that it is impossible for the tear duct to carry it away; hence, there will be a continuous overflow of tears down the horse's face. The formation of a film or scum over the eye need not cause alarm if the eye shows no ...

... care of him than of herself, stays not so long as only to put on a shift. And down from the ridge of the hard bank, supine he gave himself to the sloping rock that closes one of the sides of the next pit.

Hardly had his feet reached ...

There is always a certain amount of weeping shown at the inner angles. This is owing to a defect in the lachrymal duct. STOP—The "stop" or hollow between the eyes is well marked, as in the Bulldog, or even more so; some good specimens exhibit a hollow deep enough to bury a small marble. NOSE—The nose must be short and well turned up between the eyes, and without any indication of ...

... minute, russet-featured gentleman; is precise in dress, neat in taste; gets over the ground quietly and quickly; has a full, clear, dark eye; has a youthful clerical countenance; has given way a little to facial sadness; is sharp and serious; has a healthy biliary duct, and has carried dark hair on his head ever since we knew him; is clear-sighted, shy unless spoken to, and cautious; is free and generous in expression if trotted out a little; is no bigot; dislikes fierce judgments and creed-reviling; likes visiting folk who are well off; wouldn't ...

... distributed in Nature, alike among animals and plants. This is indicated by the frequency with which the word "musk" forms part of the names of animals and plants which are by no means always nearly related. We have the musk-ox, the musky mole, several species called musk-rat, the musk-duct, the musk-beetle; while among plants which have received their names from a real or supposed musky odor are, besides several that are called musk-plant, the musk-rose, the musk-hyacinth, the musk-mallow, the ...

... single tube called the vas deferens, which passes as a part of the spermatic cord from the scrotum, up through the groin and over the pubic arch into the pelvic cavity, passing down back of the bladder where it is slightly dilated into an ampulla, beyond which the duct is again contracted into a narrow tube, and the two ducts, one from either side, converge and pass into the prostate gland, where they ...

... above you still, Which, utterly incomprehensible, Is out of rivalry, which thus you can Love, though unloving all conceived by man— What need!

... of the testicles, in which the sperm-cells or spermatozoa are evolved, of a coiled duct leading there from, and of the distinctive male sex organ, the penis.
