After the usual process of maceration, the bones appeared white, and exceedingly compact in their tissue, and, with the exception of their anchylosed condition, are perfectly normal—their form in every respect not appearing to differ from the general characters by which these ver- tebra; are known. The most remarkable feature in the whole preparation—and evidently the result of a former dislocation forwards—is the position of the atlas; which, on the right side especially, is pushed forwards and upwards from off the articulating surface of the axis, so as to cause the odontoid process to present itself nearly in the centre of the circle of the atlas. A bridge of bone exactly half-an-inch in length, and varying from three to four lines in breadth, passes nearly hori- zontally forwards, from the odontoid process to the atlas, as described above, and connects
