until obstructed at the central points within the papillae. On dividing the penis transversely they are seen, one on each side of a larger and thicker water vessel. This central vessel appears to be an artery and terminates in the extremity of the double head. The urethra runs in contact along the under surface of the penis as far as the verge of the anus where it opens. A pair of considerable muscles rise laterally from the sphincter ani, with the fibres of which they are closely united, and are inserted, one on each side into the penis as it leaves the pelvis. There are two moveable bones resembling those in the kanguroo, placed upon the symphysis of the ossa pubis.
Mr. Home [?] in his description of the head of the above mentioned animal in the Philosophical Transactions for 1600, says it has two grinding teeth on each side, both in the upper and under jaws. There certainly is the appearance of two and sometimes of three, but in reality there is no more than one; for though the face of each be divided by one or more ridges yet its base is perfectly uniform without any division. In the same paper he says the tongue is extremely short, not half an inch long and the moveable part not more than one-fourth of an inch. It may easily be conceived that the tongue from which he takes his description had from long immersion in spirits been considerably reduced from its original size. That it must have been so the following description will evince. When the mandibles are held open and the opening into mouth exposed, there is an appearance of two tongues, and a spectator would readily appropriate one to the mandibles
