CHAPTER IX -CALCULATIONS RELATING TO BHADows. 277 is doubled ; with the (resulting) quantity the measure of the (whole) day-time is divided. It should be made out that this gives rise, according to the mathematical work (known as Sara sigraha, to the portion of the day elapsed in the forenoon and also to the portion of the day remaining in the afternoon. An estample in Mustration there 9;. The (length of the) shadow of a man is 3 times (his height).

The rule for arriving at the (corresponding number of) ghata when the portion of the day (elapsed or to elapse) has been arrived at (alreay. 10s. The (known) measure of (the duration of) the day multi plied by the numerator and divided by the denominator of bhe fraction representing the (already arrived atportion of the day (elapsed or to elapse) gives rise to the ghota8 elapsed in relation to the forenown, and to the gicts to elapse in relation to the afternoon. An example in 20/8tration there 11. In a region without the equinoctical shadow, A part of bhe day has elapsed; (or in relation to the afternoon), the remaining portion (of the day which has to elapse) is also है. What are the ghata8 (corresponding to this a portion) There are, (it may be taken), 80 glcts in a day. The rule for arriving at the time taken up by a prize-fight between gymnasts. 12. I'he day diminished by the sum of he portion of the day elapsed and of the portion (phereof) remaining to elapse, when brought into the form of time (measured by ghat03), gives rise to the (required duration of) time. The measure of the shadow of a pillar divided by the measure of (the height of) the pillar gives rise to the measure of the ahadow of a man (in torms of his own height).
