Note 843 — Chapter IX
Reading edition
Kästner, p. 161. In one place Cossali shows, that Cardan had transported all the quantities of an equation on one side, making the whole equal to zero; which Wallis has ascribed to Harriott, as his leading discovery, p. 324. Yet in another passage we find Cossali saying: una somma di quantità uguale al zero avea un’aria mostruosa, e non sapeasi di equazion si fatta concepire idea, p. 159.
