A List of the Teeth and Bones sent over by George Croghan, Esquire, February 7, 1767, from Philadelphia.

To Lord Shelburne.

Two of the largest tusks, or teeth, one whole and entire, above six feet long, the thickness of common elephants teeth of that length.

Several very large forked or pronged teeth; a jaw-bone, with two of them in it.

To Doctor Franklin.

Four great tusks, of different sizes.

One broken in halves, near six feet long.

One much decayed, the center looks like chalk, or lime.

A part was cut off from one of these teeth, that has all the appearance of fine white ivory.

A joint of the vertebrae.

Three of the large pronged teeth; one has four rows of fangs.

Besides the above, Captain Owry, an Officer who served in the country during the last war, now living at Hammersmith, hath a small tusk, as if of a calf elephant, the surface of a fine shining chestnut colour, and a recent look; and a great pronged tooth, larger than any of the above, which were also brought from the same licking place.
