The illustration shows how the pudding may be cut into two parts of
exactly the same size and shape. The lines must necessarily pass through
the points A, B, C, D, and E. But, subject to this condition, they may
be varied in an infinite number of ways. For example, at a point midway
between A and the edge, the line may be completed in an unlimited number
of ways (straight or crooked), provided it be exactly reflected from E
to the opposite edge. And similar variations may be introduced at other
places.
