whole numbers the space passed over by the moon during one tithi, which 
amounts to 603 of the 620 parts of a nakshatra. And in the same time, 
viz. in the duration of a tithi, the sun advanced just forty-five such parts. 
I will just venture on mentioning that a reference to these forty-five parts 
is perhaps contained in v. 26. There some manuscripts read not “ nava- 
bhir” but “ navatim”, and Somakara explains “ navatibhir” ; if we 
one of these latter readings, the verse directs us to divide the “ suryarksha- 
bhagan” by ninety and then to multiply the result by two, which is the 
same thing as dividing them by forty-five. This is, however, only a con¬ 
jecture, and I am unable to give a satisfactory translation of the verse. 
Let us now turn to the verses referring to the adhimasas. The yuga 
containing sixty-two lunar months to sixty solar months two of the lunar 
months had to be treated as excessive (adhimasa). To this arrangement 
manifestly refers v. 37, although all its words are not qnite clear. The 
editor of the Jyotisha hesitatingly renders the first word by “ two less”, 
pointing out at the same time that Somakara seems to explain “ dvi” by 
“ dinam” (the words of the latter are : 
; the latter explanation really appears to be the right one. 
That the word “ dvi”, strange as it may appear, is used in the sense of 
“ day” in several passages of the Jyotisha cannot be doubted (cf. p. 5 of 
Prof. Weber’s edition), and if we take it in that sense, the verse may be 
translated as follows : “ a day diminished by its sixty-second part is to be 
deducted from the sun (the solar measure), etc.” A (savana) day of 603 
kalas diminished by its sixty-second part (9 ff) equals 593 kalas, which 
is the length of a tithi, and thirty solar days being equal to thirty-one 
tithis, the verse apparently states in what manner the difference of solar 
and lunar time sums itself up. The word “ saparvanam” or “ saparvanah” 
must therefore express in some manner the period during which the men¬ 
tioned difference amounts to one tithi; it may perhajos be translated “ at 
each parvan”, parvan denoting either the new moon parvan or the full moon 
parvan only. (Prof. Weber is inclined to refer the “ dvi” in dvyunam to 
the two lavas which constitute the difference between Garga’s lunar day 
and savana day ; but this is impossible for two reasons ; firstly, the division 
of the day into lavas is not made use of in the Jyotisha, and secondly, the 
difference necessitating the establishment of two adhimasas is not between 
lunar time and savana time, but between lunar time and solar time, 1860 
tithis being equal to 1800 solar days). The second half of the verse pre¬ 
sents no difficulties” produced by which there are formed in addition two 
excessive months in the middle and at the end (of the yuga).” The thing 
was therefore managed in this way that the thirty-first and the sixty-second 
lunation of the yuga were not counted but combined with the following 
ones into one month. It is well known that the advanced Indian astro-
