It seems to be a mistake. For it was intended to construct a Fire-altar having an area equal to 101½ square puruṣas. Now the method adopted produces one with an area of 108 1/14 square puruṣas. So 108 1/14 − 101½ or 6 4/7 square puruṣas are in excess. In round numbers this might be stated as equal to 7 square puruṣas. But "thirteen" cannot be justified. So I think that here again the text should be amended to \*sapta\* or "seven." - [Previous: c17.72](https://indike.org/pramana/ins.science.datta-1932.c17.72) - [Next: c17.74](https://indike.org/pramana/ins.science.datta-1932.c17.74) - [Up: c17](https://indike.org/pramana/ins.science.datta-1932.c17) --- Source: [https://indike.org/pramana/ins.science.datta-1932.c17.73](https://indike.org/pramana/ins.science.datta-1932.c17.73) · Pramāṇa
