' 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 

 piir of sides will describe a conic. Maclaurin developes this into a general method of reducing the description of a curve to 

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