    Besides these instances, the effects of absorption in the tusks of elephants are often seen; sometimes in sawing these bodies, iron balls, spear heads, &c. are met with, which have been forced into them in attempting to kill these animals. These extraneous substances are always found loose, having a space in which they can be moved. This could never happen, unless there were some action going on, by which part of the bone could be removed, and there is no other mode in which it can be effected, but through the medium of the absorbent vessels. [As the editor will have occasion in the chapter treat- ing of the destruction of the roots of the temporary teeth, to make some remarks concerning the phenomenon here alluded to, it will not be necessary, in this place, to enter upon its further explanation.] [ARTICULATION OF THE TEETH.] The teeth are fixed in their sockets by that species of articulation called gomphosis. They are attached to the alveolar cavity by a strong periosteum, which is extended over the fangs, and which also lines the socket; it is connected to the gums at the neck of the tooth, and it is vascular, like the periosteum in other parts of the body. [STRUCTURE OF THE TEETH.] It is very extraordinary that Mr. Hunter should have considered the teeth as devoid of internal circulation, and destitute of the living principle. The structure of the teeth is similar to that of any other bone, and differs only in having a covering which is called enamel, for the exposed surface, and in the bony part being more dense.
