¹ For a purely fanciful derivation from the corresponding number of strokes, see W. W. R. Ball, *A Short Account of the History of Mathematics*, 1st ed., London, 1888, p. 147; similarly J. B. Reveillaud, *Essai sur les chiffres arabes*, Paris, 1883; P. Voizot, "Les chiffres arabes et leur origine," *La Nature*, 1899, p. 222; G. Dumesnil, "De la forme des chiffres usuels," *Annales de l'université de Grenoble*, 1907, Vol. XIX, pp. 657-674, also a note in *Revue Archéologique*, 1890, Vol. XVI (3), pp. 342-348; one of the earliest references to a possible derivation from points is in a work by Bettino entitled *Apiaria universae philosophiae mathematicae in quibus paradoxa et noua machinamenta ad usus eximios traducta, et facillimis demonstrationibus confirmata*, Bologna, 1545, Vol. II, Apiarium XI, p. 5.
