Adh: LIII. Sl. 26-28.] त्रिपञ्चाशोऽध्यायः 429 added an eighth part of itself. That will give the width of the door; and thrice this will be its height. The width of Brahmin house is 32 cubits. ²⁴⁄₄ is 6. This is to be taken as 6 digits. Add 18. i. e., 6+18 = 24 digits. 24+ ⅛ of 24 = 27 digits. This is its breadth and 27 × 3 = 81 digits, its height. उच्छ्रायहस्तसंख्यापरिमाणान्यङ्गुलानि बाहुल्यम् । शाखाद्वयेऽपि कार्यं सार्धं तत् स्यादुदुम्बरयोः ॥२६॥ उच्छायात्सप्तगुणादशीतिभागः पृथुत्वमेतेषाम् । नवगुणितेऽशीत्यंशः स्तम्भस्य दशांशहीनोऽग्रे ॥२७॥ Slokas 26-27.—The thickness of the two side-frames of the door is as many digits as the height numbers cubits. One and a half times this gives the thickness of the threshold and the upper-block. The breadth of all the four pieces is an eightieth part of seven times the door-height. An eightieth part of nine times the height (of a storey) gives the width of a pillar at the bottom; and the same lessened by a tenth is its width at the top. A pillar of the ground floor in a King's house will have a width of about 1 cubit and 5 digits at the bottom and about 1 cubit and 2 digits at the top. Its circum- ference is thrice the width. समचतुरस्रो रुचको वज्रोऽष्टाश्रिर्द्विवज्रको द्विगुणः । द्वात्रिंशता तु मध्ये प्रलीनको वृत्त इति वृत्तः ॥२८॥ Sloka 28.—A pillar that is perfectly square in the middle (leaving off the two ends) is called Ruchaka; one that is octagonal, a Diamond; one with sixteen angles (or sides), a double Diamond; one with 32 sides, Praleenaka; and a round one is called a cylinder.
