That magnitude is infinitely divisible may be shown by mathematical lines. Thus


Let the two parallel lines A B C D be extended infinitely. Draw the line F E. From the point A draw lines to C D. Since D E is infinitely long and infinite number of separate lines may be drawn to it each of which would divide F E without a pofsibility [possibility] of reaching F.

The atomic theory seems to show that [the] ultimate atoms are invariable in weight and consequently practically indivisible. It is well known the elements in chemical compounds unite always in precisely the [same] proportions. Now if these atoms could in any way be changed in size or shape this would not be the fact.
