________________ 280 GANYALBASANG RANA, product is diminished by the measure of the interval between the wall and the style. The difference (80 obtained) is divided by the very measure of the human sbadow (referred to above). The quotient so obtained happens to be the measure of (tbat portion of) the style's shadow which is on the wall. An example in illustration thereof.. 22. A pillar is 20 hastas (in height); the interval between (this) pillar and the wall (on which its shadow falls) is 8 hastas. The human shadow (at the time) is twice (the man's height). What is the measure of (that portion of) the pillar-shadow which is on the wall ? The rule for arriving at the numerical value of the measurement of the interspace between a wall and a pillar, when the height of the pillar and the numerical value of (that portion of) the shadow thereof which has fallen upon the wall are (both) known. 23. The difference between the height of a pillar and that (of its shadow) cast on (wall), multiplied by the moasure of the human shadow (in terms of the man's height), gives rise to the measure of the interspace between that (pillar) and that (wall). This value of the interspace divided by the difference between tho height of the pillar and that of the portion of) the shadow thereof cast on (the wall), gives rise to the measure of the buman shadow (in terms of the man's height). An esample in illustration thereof. 24. A pillar is 20 hastas (in height); and the (portion of its) sbadow on a wall is 10 (hastas in height). The buman shadow (at the time) is twioe (the human height). What may be the measure of the inters pave between the pillar and the wall ? 14. This rule and the one in atann 98 following fire the converse Onsen of ther the instans$1 above,
