Note 143 — PART V. GENERAL VIEWS RESPECTING THE SOLAR SYSTEM.
Reading edition
The law of progression is this: That if 4 represent the distance of Mercury from the sun, all the other planets in succession will have their distances generally represented by the expressions 4 + 3 . 2°, or 7 for Venus; 4 + 3 . 21, or 10 for the earth; 4 + 3 . 22, or 16 for Mars; 4 + 3 . 23, or 28 for the new planets; and so of the rest.
