he points of division; also lines of level through the latter. The radii drawn intercept equal arcs on the rolling circle C H M. While the first of these arcs rolls upon AB the point T turns through the angle TRl about R and reaches the line of level through point 1. But T is always at the distance… … After what has preceded, the figure may be assumed to be self-interpreting, each position of Tbeing joined with the position of R which determined it. 174. Were a tangent wanted at any point, as T^, we have, as before, to determine the point ofcontact of rolling circle and line when T reached T,,…
