Sloka. 56. Astrologers say that the (lengths) measures of the six signs beginning with Mesha are represented by the numbers 20, 24, 28, 32, 36 and 40 respectively. The same figures taken in the inverse order give the measures of the six signs from Thula onward.
It will be seen that the figures given in the sloka in the text aggregate 360 and are the measurements in degrees of the 12 signs which they subtend at the centre.

Thus it is seen that the several measurements mentioned in the sloka in the text when multiplied by 10 give the Chashakas (200, 240, 280 &c. in time) of the several signs. These figures are useful in finding out the relative lengths of the several parts of a human body (see Adhyaya III, sloka 76).
