Note 17 — PROPORTION.
J. F. (John Francis) Rigaud translation
It is believed that this treatise, like many others promised by the author, was never written; and to save the necessity of frequently repeating this fact, the reader is here informed, once for all, that in the life of the author prefixed to this edition, will be found an account of the works promised or projected by him, and how far his intentions have been carried into effect.
