278 G. Thibaut —Vardha Mihira^s Panchasuldhdntihd. [No. 2, 
indicates the number of Mercury’s revolutions. This number agrees 
neither with the one stated in the known Siirya Siddhanta (17,937,060) 
nor with the doctrine of Aryabhata who reckons 17,937,020 revolutions 
of Mercury to one yuga (Aryabhata, p. 6) ; on the other hand it does not 
differ from the number assumed in the Paulisa Siddhanta (Colebrooke, 
Essays, II, p. 365). Mercury’s kshepa finally is stated in line 17. We 
multiply the kalpady-ahargana by 17,937,000 and divide by the days of 
a yuga. The result is 148° 17'and about 6"; the last quantity is not 
stated by Yaraha Mihira. 
We conclude with Venus. According to line 15 it performs ten re¬ 
volutions in 2,247 days, consequently one revolution in 224'7 days. 
According to line 16 we have to add 10‘5" for each revolution to the mean 
place of Venus as calculated in line 15. Venus passes through so many 
seconds in 0‘00182 of a day. We deduct this amount from 224*7 and 
divide by the remainder the days of the yuga. The quotient, 7,022,388, 
indicates the number of revolutions that Venus performs in one yuga, 
a number in which the Siirya Siddhanta of the Panchasiddhantika again 
agrees with the Aryabhatiya (p. 6) and the Paulisa Siddhanta, while 
the known Siirya Siddhanta reckons 7,022,376 revolutions of Venus to 
one yuga. Lastly to calculate the kshepa we multiply the kalpady- 
ahargana by 7,022,388 and divide by the days of a yuga. The result is 
8 s 27° 30' 35", which positive quantity is turned into a negative one by 
being deducted from an entire revolution or twelve signs. The remain¬ 
der is 3® 2° 29' 25" which quantity is equal to 332,965 seconds. The text 
says 332,961; but most probably we have to read (in line 18) instead 
of which emendation would remove the discrepancy. 
In addition to the rules translated and explained in the above the 
chapter on “ Siirya Siddhanta, madhyagati ” contains a few more verses 
which as it appears state a so-called bija to be applied to the positions 
of the planets resulting from the general rules. These verses, which 
together with those already quoted constitute the entire chapter, run as 
follows :
