Nb Having scattered the Lincolnshire bands, he suddenly turned upon Warwick with his army, and caught him wholly unprepared.
Taking the case where the motion is strictly in two dimensions, we may write as the polar equation of the surface at time t r =a cos nB cos pt, (4) where p is given by p2 = (n3_ n)..
