Roman miles, which are equal to 678 British miles. The eastern coast from the mouth of the Ganges to Cape Comorin was reckoned at 16,000 stadia, or 1838 British miles; and the southern (or south-western) coast, from Cape Comorin to the mouth of the Indus at 3000 stadia more[1] than the northern side, or 19,000 stadia, equivalent to 2183 British miles.
The close agreement of these dimensions, given by Alexander's informants, with the actual size of the country is very remarkable, and shows that the Indians, even at that early date in their history, had a very accurate knowledge of the form and extent of their native land.
On the west, the course of the Indus from Ohind, above Attok, to the sea is 950 miles by land, or about 1200 miles by water. On the north, the distance from the banks of the Indus to Patna, by our military route books, is 1143 miles, or only 6 miles less than the measurement of the royal road from the Indus to Palibothra, as given by Strabo on the authority of Megasthenes. Beyond this, the distance was estimated by the voyages of vessels on the Ganges at 6000 stadia, or 689 British miles, which is only 9 miles in excess of the actual length of the river route. From the mouth of the Ganges to Cape Comorin the distance, measured on the map, is 1600 miles, but taking into account the numerous indentations of the coast-line, the length should probably be increased in the same proportion as road distance by one-sixth. This would make the actual length 1866 miles. From Cape Comorin to the mouth of the Indus there is a consi-
