 1 I  |    regards the force or ease, the form and rapidity, of the motions
 2 I  |    fatigue in our muscles, we can form a general idea of what we
 3 I  |   afforded by this comparison, to form a clear and precise idea
 4 I  |      weight. But there is another form of mill wheels, what is
 5 II |          a weight, of a spherical form: A B, a horizontal line
 6 II |           continually changes the form of its manifestation.~Let

 9 II |      power is also present in the form of steam engines.~We see,

12 III|       that which the earth in the form of gravity exerts upon a
13 III|      carbon burned with oxygen to form carbonic acid, gives as
14 III|  combustion, which appears in the form of heat. In the water which

16 III| equivalent quantity in some other form; it is thus neither increased
