SLin perforins 2,850 revolutions in 1,040,953 days. Both numbers can 
be reduced by 19. In order therefore to find the place of the sun at a 
given time or, in Indian terminology, for a given ahargana, we multiply 
the ahargana by 150 and divide the product by 54,787. The result 
represents the mean place of the sun in the tropical sphere. 
In the same adhyaya we read the following rule for calculating the 
mean place of the moon ; 
(The translation will show what emendations of the text are re¬ 
quired.) “ Multiply the ahargana by 38,100, subtract 1,984 and divide 
by 1,040,953 ; the result is the mean place of the moon.” 
The kshepa being set aside the rule is easy to understand. The 
multiplier is the number of the sidereal months contained in the yuga 
of the Bomaka Siddhanta ; the number of the civil days of the same 
period forms the divisor. The quotient represents the mean place of the 
moon in the tropical sphere. 
While the preceding rules regarding the mean places of sun and 
moon gave no information about the elements of the Bomaka which we 
might not have directly derived from the statement concerning the 
nature of the yuga and were chiefly interesting as confirming the latter, 
a new element is furnished by the next following verse which refers to 
the anomaly of the moon : 
Vi ' 
(Without translating the compound which refers to the kshepa, and 
only remarking that the last words are an emendation of 
which is the reading exhibited by the manuscripts we render :) “ Multiply 
the ahargana by 110 and divide by 3,031; the result is the moon’s kendra 
at the time of sunset at Avanti.” 
The last words indicate the time of the day from which the calcu¬ 
lations according to the Bomaka Siddhanta have to start and the Meridian 
employed; they will not be considered here as they are important only 
ii viewed in connexion with the kshepa. The kendra performing 110 
revolutions in 3,031 days we obtain by division 27^ 13^ 18' 32'7' as the 
time of one revolution of the kendra or, according to the Greeks’ and 
our own terminology, of one anomalistic month. The manner in which 
we are here taught to calculate the moon’s mean anomaly seems to be 
another interesting proof of the Bomaka Siddhanta standing in a speci¬ 
ally close relation to Greek astronomy. The Indian systems in general
