OF PROPENSITY TO MOTION, REPETITION AND 

 IMITATION. 



I. Accumulation of fen formal power in hemiplagia, in 

 JliCj.. i'i (old fi; cj fever, in the locomotive mufcles, 

 in the organs oj Jenfe. Produces propenfity to action. 

 II. Repetition by three fenforial powers. In rhimes 

 and alliterations, in mufic, dancing, architecture,

 perpetually produced and expanded in moving the
