Page from the //Encyclopaedia Britannica// of 1797[^Napier’s Rods in "Inland Navigation", //Encyclopaedia Britannica//, 3rd Edition, 1797, plate CCCXLIV, Andrew Bell copperlplate. Original print article.^] (This was the first edition to be bound in volumes and was the same edition in which the article on 'Motion' erroneously rejects Newton's theory of gravitation in favour of gravity being caused by the classical concept of the element of fire).
