' Newton had discovered the theorem that if two angles of given magnitude be movable round their vertices, and the 

 intersection of a side of the one with a side of the other be made to travel along a straight line, the intersection of the other

 the description of another curve of lower order ; the theory is one of much beauty and power '.—D. N. B.
