 ``` CHAPTER XV. 167 thumb and the small finger at their widest possible stretching, is called vitasti and also kishku. The distance between the ends of the fourth or ring- finger and the thumb, both being stretched out, is called gokarna. The distance between the ends of the index-finger and of the thumb is called karabha, and is reckoned as equal to two-thirds of a span. The distance between the tops of the middle finger and of the thumb is called tdla. T'he Hindus maintain that the height of a man is eight times his tdla, whether he be tall or small; as people say with regard to the foot, that it is one-seventh of the height of a man. Regarding the construction of idols, the book Samhitd says :— "T'he breadth of the palm has been determined as 6, the length as 7 ; the length of the middle finger as 5, that of the fourth finger as the same ; that of the index- finger as the same minus ^ (i.e. 4^); that of the small finger as the same minus ^j (i.e. 3-^); that of the thumb as equal to two-thirds of the length of the middle finger (i.e. 3-^-), so that the two last fingers are of equal length." By the measurements and numbers of this passage, Page the author means idol-fingers. After the measure of the krosa has been fixed and The relation . , , , between found to be equal to our mile, the reader must learn yojana,mi\Q, that they have a measure of distances, called yojana, "" ■'"'''"'' ' which is equal to 8 miles or to 32,000 yards. Perhaps somebody might believe that i kroh is ^ ^ farsakh, and maintain that the farsakhs of the Hindus are 16,000 yards long. But such is not the case. On the contrary, I kroh = -^- yojana. In the terms of this measure, Alfazari has determined the circumfer¬ ence of the earth in his astronomical handbook. He calls it jun, in the plural 'ajwdn. The elements of the calculations of the Hindus on Rf/atwn the circumference of the circle rest on the assumption go 8c between ```
