Flint-gravel, and whitish chalky sand, flints subangular, average size of fragments, 3 inches diameter, but with some large unbroken Chalk flints intermixed, cross stratification in parts. Bones of mammalia, grinder of elephant at b, and flint implement at c, 10 to 14 feet. 5. Chalk with flints. a. Part of elephant's molar, 11 feet from the surface. b.
But this resemblance is confined to general appearance, as in the prominence of the canines, and in the cutting shape of the molar teeth. For the teeth really differ much: thus the dog has on each side of the upper jaw four pre-molars and only two molars; while the Thylacinus has three pre-molars and four molars. The molars also differ much in the two animals in relative size and structure.
Mrs Adams felt nervous, and remonstrated, but being persuaded after a time to try again, she gave a vigorous pull, which drew from the unhappy man a terrible yell, but did not draw the tooth. "This'll never do," groaned John, feeling the rebellious molar with his finger; "it's as firm as a copper bolt yet. Come, wife, I'll try another plan. You go outside that door an' do what I bid you.
If the grinding faces of an upper and of a lower molar of the same side are applied together, it will be seen that the opposed ridges are nowhere parallel, but that they frequently cross; and that thus, in the act of mastication, a hard surface in the one is constantly applied to a soft surface in the other, and vice versa.
Describe the appearance of the teeth in an overshot or undershot jaw. Describe the appearance of sharp molar teeth; a scissor-mouth. What are the causes of decayed teeth? Inflammation is a pathological condition of a tissue, characterized by altered function, disturbance of circulation, and destructive and constructive changes in the irritated part.
They have two molar teeth less in each jaw than the Cebidae, the other family of American monkeys; they agree with them, however, in the sideway position of the nostrils, a character which distinguishes both from all the monkeys of the old world. The body is long and slender, clothed with soft hairs, and the tail, which is nearly twice the length of the trunk, is not prehensile.
They sew them in the lining of the pocket, lest they should be pulled out with the handkerchief and lost; they will grant the loan of them to a neighbour tormented by some refractory molar. "Lend me thy tigno: I am suffering martyrdom!" begs the owner of a swollen face. "Don't on any account lose it!" says the lender: "I haven't another, and we aren't at the right time of moon!"
If the germs, or ova, or seed, or offspring partially developed, survive more or survive less, it is either because their molar or molecular structures are unlike the average ones, or because they are affected in unlike ways by surrounding agencies.
Edward was standing ginger-beer like a gentleman, happening, as the one that had last passed under the dentist's hands, to be the capitalist of the flying hour. As in all well-regulated families, the usual tariff obtained in ours, half-a-crown a tooth; one shilling only if the molar were a loose one.
The skull of this great Eocene sea-monster, in fact, shows by the narrow and prolonged interorbital region; the extensive union of the parietal bones in a sagittal suture; the well-developed nasal bones; the distinct and large incisors implanted in premaxillary bones, which take a full share in bounding the fore part of the gape; the two-fanged molar teeth with triangular and serrated crowns, not exceeding five on each side in each jaw; and the existence of a deciduous dentition its close relation with the Seals.
