Logistical ARITHMETIC, a name sometimes employed for the arithmetic of sexagesimal fractions, used in astronomical computations. Shakerly, in his Tabula Britannica, has a table of logarithms adapted to sexagesimal fractions, which he calls logistical logarithms; and the expeditious arithmetic, obtained by means of them, he calls logistical arithmetic. The term logistical arith-
metics, however, or logistical, has been used by Vieta and Arithmetic others for the rules of computations in algebra. || Ar. ed. II.
