 cians, who reprefent them likewife by figures, 

 fuppofe the circular motion to be generated of the 

 perpendicular and the horizontal, and, to make 

 ufe of their language, produced by the diagonal 

 of their fquares. 



I fliall not infifl on the analogies of the genera- 

 tion of colours and forms, to thofe of the genera- 

 tion of movements ; and which aftually exift, be- 

 tween the white colour, the ftraight line, and felf-

 darknefs, vacuity, and left. I ihall not pretend 

 to unfold the infinite combinations which might

Of all movements, the harmonic, or circular
