✦ Synopsis

Duodecimal System. HENRY LEFFMANN (Bull. Wagner Free Institute of Science, I928, 3, 3-6) has summarized the advantages of the duodecimal system in a speculative essay. The base of the system is divisible without fractions by 2, 3, 4, and 6. The dozen and the gross are extensively used units in merchandizing. The system is now in use to a limited extent, as is shown by the following examples. The foot is divided into 12 inches, the inch into I2 lines, and the line into I2 points. The year has I2 months; the face of the clock has I2 major divisions; and I2 pence make a shilling. The fathom (6 feet) and the league (3 geographical miles) are really based on a duodecimal system. It is suggested that two new figures or signs be introduced between 9 and IO, that these signs be an inverted J and an inverted V, and that they be designated, respectively, as " kal " and " gan." J.
