13 I  |           able to set them all in motion by means of a weight sufficient
14 I  |         of the arm, may be set in motion. The weight of 100 pounds

30 III|      destroyed, and then produces motion. We must rather conclude
31 III|        this that heat itself is a motion, an internal invisible motion
32 III|     motion, an internal invisible motion of the smallest elementary
33 III|         of bodies. If, therefore, motion seems lost in friction and

36 III|         whole motive power of the motion of heat, which remains constant
