As in other Eastern countries the linear unit is usually a cubit, the _hástha_ or _háth_, divided into 24 digits. Traces of the Egyptian increased cubit are to be found. In a classical work on architecture, the Mánasára, the Hástha, of 24 digits for timber, is increased to 25 for temples, to 26 for houses, to 27 for municipal buildings and land. The addition of 3 digits to the 24 of the Egyptian common cubit would give 27 digits, approximately equal to the 28 smaller digits of the royal cubit. In Southern India the cubit is sometimes the _mūyangál_ (_mūyam_, cubit; _kál_, leg), the length from the knee to the ankle. In Malabar the unit is the Kol = 28-1/4 inches as used for timber; but for land it seems to have increased to 30 inches. The kol was probably 3 spans or half-cubits of 9·41 inches. A guz brought by the Moslems, = 33 inches, has established itself in Bengal. It was probably 3 Beládi feet of 10·944 inches. The Portuguese Covado of 3 spans = 27·17 inches, usually taken as 27 inches, has established itself in Western India. It is divided into 48 digits, of which two-thirds, i.e. 32 digits = 18 inches, are the usual cubit; 1/8 of this = the English nail. All these measures appear to have been modified by the English foot and inch. Native itinerary measures are rough and variable; the Koss of 100 fathoms is the usual standard. Land-measures are of course very variable. 12 guz, usually = 33 feet, make a cord or chain, and 5 cords make a Jarib = 10 rods. A square jarib = 100 square rods, is the usual Bigha of Northern India = O·625 acre. Another unit is the Mah of 100 rods 12 × 12 feet = 1600 square yards, about half the above bigha. Land-units, like most other units, can be divided into 16 annas, so that the anna of the bigha is 200, that of the Mah is 100, square yards. In Madras the unit of land measure is the Káni (cawny) = 1-1/3 acre of 24 grounds = 6400 square yards. So there appears to be a common unit of about 1600 square yards, with its anna or sixteenth = 100 square yards or 10 yards square. Five káni make a Véli, the usual extent of arable land which can be cultivated for rice or other wet crops by a peasant with a yoke of oxen. Everywhere there are seed-measures of land, as in other countries. _Weights_ These are derived from a coin-weight basis, the silver rupee-weight or Tola in most parts, the golden pagoda-weight or Varahan in the south of India. In each case 80 of these coin-units made a Sér. (See Indian Coinage, in Chap. XIII.) The Bengal sér, 80 tolas of 180 grs. = 14,400 grs. The Madras sér, 80 varahan of 54 „ = 4320 „ The Bombay sér was based on another gold coin, the _tanc_ (gold) of a little over 68 grains, 72 of which = 4900 grains.
