, Each pillar is in itself a distinct piece of workmanship;
it is separable from all the adjacent columns, and then is
‘itself separable into distinct joints, whose articulation is
as perfect as human exertion could have formed them,
the extremities of each joint being concave or convex,
which is determined. by the terminations of the) joints
with which it was united ; but there is no regularity as to
the upper or lower extremity being concaveor convex;
the only law on this point is, that the contiguous joints
