...D, having such values that B=D A C' then A is said to have the same ratio to B that C has to D, or **the ratio of A to B is equal to the ratio of C to D.** "When four quantities have this relation to each other, compared together two and two, they are said... | |

...where the wires diverge and meet again. When the resistances of A, B, C, and D are so related that **the ratio of A to B is equal to the ratio of C to D,** then the points E and F are at the same level or the same potential with regard to electricity, and... | |

...the measure of the ratio of A to B is the same as the measure of the ratio of C to D, and therefore **the ratio of A to B is equal to the ratio of C to D.** Hence any of the preceding propositions in which it has been proved that the scale of A, B is the same... | |

...short: if a double ratio comes from a speed B and a triple ratio from a speed A, then, permutatim, **the ratio of A to B is equal to the ratio of** 3:1 to 2:1. We note that Etienne Gaudet copies this "demonstration" without comment.26 What Dumbleton... | |
