Then, since the rod is at that instant turning about the farther end A', we will have Dd for the motion of D. The instantaneous axis of the connecting rod is found by drawing perpendiculars to the directions of the simultaneous motions of its two ends, and it therefore falls at A', in the present position.

We may also refer, in further illustration of the character of the country through which a portion of this pretended "axis of maximum elevation" is made to pass, to a panorama view taken in October, 1841, by one of Major Graham's assistants from the summit of Blue Hill, where crossed by the true meridian of the monument, at the source of the St. Croix.
