At all events, the prong-buck is quite alone in the world at present, and we know no fossils which unmistakably point to it, although it has been supposed that some of the later Miocene species of Cosoryx small deer-like animals with non-deciduous horns, probably covered with hair, and molars of somewhat bovine type may have been ancestral to it, but this is little more than a speculation.
No. 9 in the collection is the skull of an adult male: No. 2 the male, nearly adult, killed by myself: Nos. 11 and 3 adult females, killed by myself: No. 12 a young male, with three molars, killed by myself: No. 21 a young male, died aboard, with three molars: No. 19, young male, died aboard, with two molars.
"I don't suppose we can blame her exactly," said Perkins, when discussing one or two of Jane's lapses from her old-time standard. "I haven't a doubt that if I'd gone for years without teeth, I'd become a regular Cheshire cat, with a new, complete edition de luxe of celluloid molars. Still, I wish she'd paid more attention to the dinner and less to Mr. Barlow's conversation last night.
And in form, the crowns of the molars are very unlike those of the Gorilla, and differ far more widely from the human pattern.
We should all, at once, agree upon placing him among the mammalian vertebrates; and his lower jaw, his molars, and his brain, would leave no room for doubting the systematic position of the new genus among those mammals, whose young are nourished during gestation by means of a placenta, or what are called the 'placental mammals.
Some of these have still a certain degree of utility, though diminished and still diminishing in size and functional importance, like our third molars or "wisdom" teeth, our fifth or "little" toes, our gall-bladder, our coccyx or tail-bone, the hair-glands scattered all over the now practically hairless surface of our bodies, and our once movable ears, which can no longer be "pricked," or laid back.
Destined to be the most turbulent and active of youths, as well as the most eloquent of men and the greatest orator of his day, Gabriel was born with one foot twisted and his tongue tied, in addition to which his size and strength were extraordinary, and already two molars were formed in his jaw.
The molars, "grinders," or cheek teeth are marked 1 to 7. Figs. The bone has been partly cut away so as to show the fangs or roots of the teeth, which are double in the molars, and even threefold in molar No. 7. The explanation of the lettering is the same as that given for Figs. B points to a "foramen" or hole in the upper jaw-bone.
In connection with the skull, I may speak of the teeth organs which have a peculiar classificatory value, and whose resemblances and differences of number, form, and succession, taken as a whole, are usually regarded as more trustworthy indicators of affinity than any others. 'i', incisors; 'c', canines' 'pm', premolars; 'm', molars.
The follicular odontoma, also known as a dentigerous cyst, is derived from the distension of a tooth follicle. It constitutes a cyst containing a viscid fluid, and an imperfectly formed tooth is often found embedded in its wall. The cyst usually forms in relation to one of the permanent molars, and may attain considerable dimensions.
