Given intervals	104	90	63	40	11
Declinations	1132	1236	1326	1389	1429	1440
Bearing the need for agreement in mind, the syllables ka, tu have been inserted in verse 17 to
make up for deficiency in syllables; āsīt ta has been corrected into aśītyā for the sake of sense, as also
deśastriṣa into mese trikha, manūnām into manūnam, and gavise into gavi; and ntare has been corrected
into nte to delete one syllable, and also make the word sensible.
In the manuscripts, after catvāriṁśacchivāśca in the 18th verse, the end of the 19th, yāmyottare kārye
and the beginning of the 20th, Viṣuvaddina(? va)samadhye have strayed. Only after these is found the
end of the 18th, mithunāntare(? nte). The portion from here, upto na divāniśi in V.9, is missing in one
set of manuscripts.
[शङ्कुच्छाया]

Gnomonic shadow

19. (Plant a gnomon at the centre of) a circle having a diameter equal to four times the gnomon. Mark the two points where the shadow of the gnomon enters the circle and emerges from it. The line joining the points is the east- west line. The line drawn perpendicular to this by means of equal intersecting circles, is the north-south line. Though the east-west line is first asked to be drawn and the north-south next, as perpendicular bisector to the east-west, it will be better if the north-south line is first drawn by means of equal intersecting circles with the two points as centres. Then using the points of intersection of the north-south line and the original circle as centres, by the same means, the perpendicular bisector forming the east-west line can be drawn, which will pass through the centre as required. On the other hand, if the east-west line is first drawn by joining the first two points, another line parallel to it and passing through the centre is to be drawn as the desired east-west line. 19a. A. संकुश्रतुविस्तारे; C. शङ्कइगुलविस्तारे in V. 9c. as noted by the scribes. c. A. अपेरैद्री; C.D. अपेरैन्द्री Thus, B1 adds in the margin, प्रति पत्र एक; d. A. यवाश्च; C.D. यवैश्च B2. adds, प्रतिपत्र एके, and B3. adds प्रति नूं ∙ B. After कार्ये one leaf missing upto दिवा पत्र एक. And all add अग्रो नास्ति ।
