... defined, from a Belgian cave, which I have carefully examined, gives no evidence of a canine tooth of a size indicative of one in the upper jaw necessitating such vacancy in the lower series of teeth which the apes present.

... from the river tribes, although they had some few words in common, so that I could not rely on my interpretation of what they said. They were all of them circumcised, and all but one wanted the right front tooth of the upper jaw. When we left these people I gave them a note for Mr. Poole, in the faint hope that they would deliver it, and I explained to them that he would give them a tomahawk and blankets, but, as I afterwards learnt, they never went ...

... and even seemed pleased with the name, yet endeavoured, by the length and growth of his beard, to conceal the circumstance that had originally procured him that denomination. This was an unusual thickness and projection of the mouth and upper jaw, which, with the huge projecting side teeth, gave that resemblance to the bestial creation, which, joined to the delight that De la Marck had in hunting the forest so called, originally procured for him the name of the Boar of Ardennes. The beard, ...

And he had what no one else in Urkey had then, a brace of gold teeth, the second and third to the left in the upper jaw, where Lem White's boom had caught him, jibing off the Head. They showed now as the slowly working lip revealed them, glimmering with a moist, dull ...

... the middle incisors, the deep gash made by the fang-like dog tooth, and between the mark of the right upper canine and those of three incisors a smooth, unscarred space.

... employs the fatal power bestowed upon it. The rattlesnake inserts its poison in the body of its victim by means of two long sharp-pointed teeth or fangs, which grow one on each side of the forepart of the upper jaw. The construction of these teeth is very singular; they are hollow for a portion of their length, and in each tooth is found a narrow slit communicating with the central hollow; the root of the fang rests on a kind of bag, containing ...

... is that disfiguring facial defect, hare-lip, due to a failure of the three parts of which our upper jaw is built to unite properly,—this triple construction of the jaw being an echo of ancestral fishlike and reptilian times when our jaws were built in five pieces to permit of wide distention in the act of swallowing our prey ...

... about the male salmon is that during the breeding- season, besides a slight change in colour, "the lower jaw elongates, and a cartilaginous projection turns upwards from the point, which, when the jaws are closed, occupies a deep cavity between the intermaxillary bones of the upper jaw." (7. Yarrell, 'History of British Fishes,' vol. ii. 1836, p. 10.) (Figs. 27 and 28.) In our salmon this change of structure lasts only during the breeding-season; but in the Salmo lycaodon of N.W. ...

It has given up angling altogether and taken to netting; and the way in which the net has been constructed out of the pair of forceps provided in the original plan of its construction is as well worth your examining as anything I know. It is a foot in length, the upper jaw is flat and broad, while the lower consists of two thin, elastic bones joined at the point, a mere ring to carry the curious yellow bag that hangs from it. In pictures this is represented as a creel in which the kind pelican carries home the children's breakfast; you are allowed to ...

I wish you had seen their faces when the shark's great head with six rows of teeth in its gaping upper jaw came abreast the deck! Half the fellows were for throwing down the bars and running, but the other half would not show white feather before the common sailors; and two or three clanking rounds brought the great shark lashing to deck in a way that sent us scuttling ...

To the right of the eye we have the mouth, which is usually shown in profile, the upper jaw being turned upward exhibiting a double row of notches or teeth.

... of the day these saurians love to stretch themselves on the shore, and install themselves comfortably there to pass the night. Crouched at the opening of a hole, into which they have crept back, they sleep with the mouth open, the upper jaw perpendicularly erect, so as to lie in wait for their prey. To these amphibians it is but sport to launch themselves in its pursuit, either by swimming through the waters propelled by their tails or running along the bank with a ...

The man to look for was tall, young, strong and active, with a very irregular set of teeth, a tooth missing from the lower jaw just to the left of the center, and another from the upper jaw a little farther still toward the left.

When seen in profile it was not unlike those of the apes we had encountered, but it was evidently even more formidable, for projecting from its nose was a stout, sharp horn, similar to that of a rhinoceros, while a pair of long tusks projected from its upper jaw. In colour the animal was a greyish brown, dark on the upper part of the body, fading to a dirty white on the lower. A serrated ridge of what might be loose skin ran along its back from the nape of the neck to the extremity of the tail, and the body appeared to be thickly ...

... peculiarities, one relative to its appearance, and the other to its properties of action, which distinguish it from those described by him. Those I saw were without that snout or trunk hanging below the end of the upper jaw; but then the males were furnished with a large shaggy mane, which gave them a most formidable appearance. And, whereas, he says those he saw were unwieldy and easily destroyed, we found some, on the contrary, that ...

... of the wolves buried his teeth too deeply in a tough portion of the flesh, and having jumped to reach it, his own weight made it impossible for him to loosen his upper jaw. There the grey wolf dangled, kicking and yelping, until the tendon of the ham gave way, and both fell heavily to the ground. From my hiding-place I sent two arrows into his body, which ended his life. The other one ran away to a little distance and remained ...

... long. Its body is slenderer than that of the whale, and its fat not in so great abundance. But this great animal is sufficiently distinguished from all others of the deep, by its tooth or teeth, which stand pointing directly forward from the upper jaw, and are from nine to ten feet long. In all the variety of weapons with which nature has armed her various tribes, there is not one so large or so formidable as this.—This terrible weapon is generally found single; and some are of opinion that the animal ...

The upper jaw is armed with minute teeth, and there are two teeth in the centre of the lower jaw, the remaining portions of the jaw being armed with two exceedingly sharp-edged bony plates. In place of a tongue, it has a round muscular process with a rough flat ...

The White Shark is bad enough, but the Sword-Fish is even worse. His aim is unerring, and his disposition so fierce that he will attack anything that comes in his path, large or small. I saw one once that ...
