He dissected several females and a male, all of which, from the state of their skeleton and their dentition, he justly supposes to have been young. However, judging by the analogy of man, he concludes that they could not have exceeded four feet in height in the adult condition. Furthermore, he is very clear as to the specific distinctness of the true East Indian Orang.
At this time in the life of the boy or girl, the possibilities for stuttering or stammering to secure a firm hold on their muscular and nervous system are very great. Next to the age of second dentition, children at the age of puberty are most susceptible to stammering or stuttering.
"Very true, ma'am I'll call for your carriage, for I suppose you have had enough of this." Mowbray carried me with him. "Come off," said he; "I long to hear Montenero descant on the merits of the dentition. Do you speak, for you can do it with a better face."
Bronzet describes a child of twelve, with only half its teeth, in whom the alveolar borders receded as in age. Baumes remarks that he had seen a man who never had any teeth. The anomalies of excessive dentition are of several varieties, those of simple supernumerary teeth, double or triple rows, and those in anomalous positions.
The adult dentition is preceded by a widely different milk dentition. Any one may, of course, deny that the teeth in either case have been adapted for tearing flesh, through the natural selection of successive variations; but if this be admitted in the one case, it is unintelligible to me that it should be denied in the other.
In the different ruminants the teeth have either begun to appear before birth, or they show themselves a few days afterwards; and in either case dentition is completed within the first month, and in dogs and cats within the first ten weeks of existence.
Now man unquestionably belongs in his dentition, in the structure of his nostrils, and some other respects, to the Catarrhine or Old World division; nor does he resemble the Platyrrhines more closely than the Catarrhines in any characters, excepting in a few of not much importance and apparently of an adaptive nature.
The Marmosets, on the other hand, exhibit the same number of teeth as Man and the Gorilla; but, notwithstanding this, their dentition is very different, for they have four more false molars, like the other American monkeys but as they have four fewer true molars, the total remains the same.
They thus constitute a grinding apparatus of great efficiency, and one which is repaired as fast as it wears, owing to the long-continued growth of the teeth. Some other peculiarities of the dentition of the horse must be noticed, as they bear upon what I shall have to say by and by.
Its dentition resembles, in some respects, that of the elephant; and from the structure of its digestible organs it can eat only vegetable food; that is, the algae, or weeds, growing on submarine rocks in shallow water. When it comes to the surface to breathe, it utters a peculiar cry, like the lowing of a cow.
