"Mandible" Quotes from Famous Books



... derived from persistent portions of the epithelium of the enamel organ, and constitutes a multilocular cystic tumour which is chiefly met with in the mandible. The cystic spaces of the tumour contain a brownish glairy fluid. These tumours have been described by Eve under the name of multilocular cystic epithelial ...

... her sorrow to the air, Stalking out of desolation came a being strange and rare— Plato's Man!—bipedal, featherless from mandible to rump, Its wings two quilless flippers and its tail a plumeless stump. First it scratched and then it clucked, as if in hospitable terms It invited her to banquet on imaginary worms. Then it strutted up ...

... with very great care. In the bay itself there are numerous cormorants, and occasionally penguins and large flights of the cut-water or shear-bill (Rhynchops nigra, Linn.). The latter is distinguished by a sharp-pointed bill closing laterally, the under mandible being about double the length of the upper one. But the most beautiful bird in the bay of Valparaiso is the majestic swan (Cygnus nigricollis, Mol.), whose body is of dazzling white, whilst the head and ...

... oak, in making roads whose rubbish serves as food. The horse in Job swallows the ground[2] in a figure of speech; the Capricorn's grub eats its way literally. With its carpenter's-gouge, a strong black mandible, short, devoid of notches, scooped into a sharp-edged spoon, it digs the opening of its tunnel. The piece cut out is a mouthful which, as it enters the stomach, yields its scanty juices and accumulates behind the worker in ...

... carnivorous habit, carnassial teeth, for example, and reduced clavicles. From a "carnivorous" alimentary canal, then, you can infer with certainty that the animal possessed carnassial teeth and the other structural peculiarities of carnivorous animals, e.g., the peculiar coronoid process of the mandible. From the carnassial tooth you can infer the reduced clavicle, and so on. "In a word, the form of the tooth implies the form of the condyle; that of the shoulder blade that of the claws, just as the equation of a curve ...

... formation of their bills. These remarkable birds are said to be another off-shoot of "the great corvine nest;" and the author of "The Vestiges of Creation" regards the hollow protuberance upon the upper mandible (which is the distinguishing feature of the family), as "a sounding-board to increase the vociferation which these birds delight to utter." The remarkable varieties in the cases, are the helmet hornbill of India, and the African rhinoceros hornbill. These ...

... knob on the palate—a swollen outgrowth of the dentary edges of the bill. Correlated with this peculiarity the maxilla usually has the tomia sinuated, and is generally concave, and smaller and narrower than the mandible, which is also concave to receive the palatal knob. In most other respects the buntings greatly resemble the finches, but their eggs are generally distinguishable by the irregular hair-like markings on the shell. In the British Islands ...

... to be numbered among the curiosities of nature. They are characterised by the disproportionately large beak. In some species this is nearly a foot in length. The beak has on the upper mandible an excrescence which in some species is nearly as large as the bill itself. The nesting habits are not less curious than the structure of hornbills. The eggs are laid in a cavity of a tree. The ...

It so closely resembles the whistling swan that only an ornithologist can recognize the difference, a yellow spot on the side of the upper mandible, near its base. The whistling swan yet remains in fair numbers, but it is to be feared that soon it will go ...

... life begets luxury, and among fruit-eaters the parrot has become an epicure. It will not swallow its food whole, and its bill deserves study. In birds generally the upper mandible is more or less joined to the skull, leaving only the lower jaw free to move. But in the parrot the upper mandible is also hinged, so that each plays freely on the other. The upper, as we all know, ...

... hidden under the carapace. Nor is it more difficult to discern that, in the appendages of the tail, the middle division appears again and the outer vanishes; while, on the other hand, in the foremost jaw, the so- called mandible, the inner division only is left; and, in the same way, the parts of the feelers and of the eye-stalks can be identified with those of the legs ...

... Above, his plumage, as described by Nuttall, is variegated with black, bright bay, and ochreous. Tail, wedged, the feathers pointed, the four outer nearly all white; sides, thighs, and vent, pale ochreous, spotted with black; upper mandible brown, the lower bluish-white; iris, hazel; legs and feet, large, pale flesh-colour. In the young bird the color is much fainter than ...

... merit the name of boatbill equally well with the bird so called, since its bill recalls the small fishing boats that we observe keel upward high and dry on our seashores. This bill is ten inches in length, and four inches in breadth at the base. The upper mandible, which is strongly convex, exhibits upon its median line a slight ridge, which is quite wide at its origin, and then continues to decrease and becomes sensibly depressed as far as to the center of its length, ...

... mute, or at least none of them had ever uttered a vocal sound to be reported by Terrans. This one did not cry out. But he staggered forward, forelimbs up, clawed digits pulling at the wooden pin transfixing his throat just under the mandible-equipped jaw, holding his head at an unnatural angle. Without seeming to notice the others of his kind, the Throg came on at a shambling run, straight at Shann as if he could actually see through the dark and had marked down the Terran ...

... the middle, and afterward taper to a sharp point. Altogether they form a tail of extraordinary length and width which the bird holds slightly elevated, so as to cause it to describe a graceful curve, and the point of which touches the soil. The beak, whose upper mandible is less arched than that of the pheasants, exactly resembles that of the arguses. It is slightly inflated at the base, above the nostrils, and these latter are of an elongated-oval form. In the bird that I have before me the beak, as well as the feet and legs, ...

... He had just taken one of the nuts end-ways into his bill, where he kept it firm by the pressure of the tongue. He then cut a transverse notch, so Mr Hooker declared, by the lateral sawing motion of the lower mandible. He next took hold of the nut by his foot, and biting off a piece of a neighbouring leaf, retained it in the deep notch of the upper mandible. Again seizing the nut, which was prevented from slipping by the elastic ...

... particularly to the South Atlantic and Gulf States, where it is very abundant; it is frequent in the Middle States, and only occasionally seen in New England. The wings are exceedingly long; they fly in close flocks, moving simultaneously. They seem to feed as they skim low over the water, the under-mandible grazing or cutting the surface, and thus taking in their food.—Vide Coues's Key to North American Birds, Boston, 1872, ...

... of the pouter-pigeon, he has enormously increased the size of the oesophagus, and has added to the number of the ribs, and given them greater breadth. With the carrier-pigeon, by increasing, through steady selection, the wattles on the upper mandible, he has greatly modified the form of the lower mandible; and so in many other cases. Natural species, on the other hand, have been modified exclusively for their own good, to fit them for infinitely ...
— The Variation of Animals and Plants Under Domestication, Volume II (of 2) • Charles Darwin

... difference is the formation of their beaks or bills. The bills of the true falcons are stronger, and have a notch in the lower mandible answering to a tooth in the upper one. Their nostrils, too, are differently formed. But another point of distinction is found in their habits. Both feed on warm-blooded animals, and neither will eat carrion. In this respect the hawks ...

... yellow, or greenish-yellow (a point by which it may be distinguished from the Florida gallinule, as the bird flies from you), the bill red tipped with pale green, and the shield (on the forehead, like a continuation of the upper mandible) light blue, of a peculiar shade, "just as if it had been painted." From that moment the boy was a new creature. Again and again he spoke of his altered feelings. He could pull the boat now anywhere I wanted to go. He was perfectly fresh, he declared, although I thought ...

... plainly seen the truth of what I started with—that the Sperm Whale and the Right Whale have almost entirely different heads. To sum up, then: in the Right Whale's there is no great well of sperm; no ivory teeth at all; no long, slender mandible of a lower jaw, like the Sperm Whale's. Nor in the Sperm Whale are there any of those blinds of bone; no huge lower lip; and scarcely anything of a tongue. Again, the Right Whale has two external spout-holes, the ...
— Moby Dick; or The Whale • Herman Melville

... a shoveller-duck (Spatula clypeata) is a more beautiful and complex structure than the mouth of a whale. The upper mandible is furnished on each side (in the specimen examined by me) with a row or comb formed of 188 thin, elastic lamellae, obliquely bevelled so as to be pointed, and placed transversely to the longer axis of the mouth. They arise from the palate, and are attached by flexible membrane ...
— On the Origin of Species - 6th Edition • Charles Darwin

... entomologists troubled very little about the live animal; they worked on corpses, a dissecting-room method which does not yet seem to be drawing to an end. They would examine with a conscientious eye the antenna, the mandible, the wing, the leg, without asking themselves what use the insect had made of those organs in the exercise of its calling. The animal was classified very nearly after the manner adopted in crystallography. Structure was everything; life, with its highest prerogatives, ...

... writing in 1684, New England women, then as now, lost their teeth at an early age. He speaks of them as "pitifully Tooth shaken." He recommended to relieve their misery a compound of brimstone, gunpowder, and butter, to be "rubbed on the mandible." This colonial remedy is still employed on New England farms. Burnaby, writing in 1759, said that New England dames had universally and even proverbially very indifferent teeth. The Abbe Robin says they were toothless ...
