As compared with those of the apes, the human wisdom teeth are degenerate; in the gorilla they are cut at the same time as the other molars; and in the lower human races they come through the gums in early youth, while in the more advanced Caucasic races they are cut only in later life or not at all.
Then he tried his "back teeth." His molars were in prime order, and his jaw power was sufficient to crack a hickory nut every time. Si crowded one corner of the hardtack as far as he could between his "grinders," where he could get a good "purchase" on it, shut his eyes and turned on a full head of steam. His teeth and jaws fairly cracked under the strain, but he couldn't even "phase" it.
The teeth were as barbarously mutilated as the skin; these had all the incisors sharp-tipped; those chipped a chevron-shaped hole in the two upper or lower frontals, and not a few seemed to attempt converting the whole denture into molars. The legs were undeniably fine; even Hieland Mary's would hardly be admired here.
There are green olives "flowing with brine," black olives "seasoned with oil," sausages of Arles "with rosy flesh, marbled with cubes of fat and whole peppercorns," legs of mutton stuffed with garlic "to dull the keen edge of hunger"; chickens "to amuse the molars"; melons of Cavaillon too, with white pulp, not forgetting those with orange pulp, and to crown the feast those little cheeses, so delightfully flavoured, peculiar to Mont Ventoux, "spiced with mountain herbs," which melt in the mouth.
"Great was our triumph as we gazed on the huge animal dead at our feet, and proud were we of having shot the first ourang we had seen, and shot him in his native woods, in a Borneo forest, hitherto untrodden by European feet. The animal was adult, having four incisors, two canines, and ten molars in each jaw; but by his general appearance he was not old.
This condition is caused by an excessive difference in the width of the jaws, unusually prominent ridges of enamel on the external face of the superior molars, and any conditions that may limit the movements of the jaw. The following symptoms may be noted. The animal has difficulty in masticating the feed because of injury to the cheeks or tongue by the sharp points of enamel.
The extinct Monotremes, to which the Promammalia belonged, must have had developed teeth, inherited from the reptiles. Lately small rudiments of real molars have been discovered in the young of the Ornithorhyncus, which has horny plates in the jaws instead of real teeth. The Ornithorhyncus or Duck-mole.
"Can you make a noise by grinding your molars together -your grinding teeth? Try it." Harry did. The noise came forth from his mouth, though it didn't sound exactly like the rattle of a rattler. "Keep on practicing, and you'll get that rattle down to perfection -that's all," nodded Tom. Spring found the young engineers restless for new fields. They longed to tackle other big feats of engineering.
He behaved handsomely about his molars, and never objected to being pulled off into remote places in his cart. When Thea dragged him over the hill and made a camp under the shade of a bush or a bank, he would waddle about and play with his blocks, or bury his monkey in the sand and dig him up again.
To this end, good cutting instruments and powerful and lasting crushers are needful. Accordingly, the twelve cutting teeth of a horse are close-set and concentrated in the fore-part of its mouth, like so many adzes or chisels. The grinders or molars are large, and have an extremely complicated structure, being composed of a number of different substances of unequal hardness.
