BlVISrONS OP THE ZODlACK^ 365 ' 



been already noticed by Capt. Wilforu in his essay 

 on Vicra^via'ditya ; and it is, therefore, unnecessary 

 tc enlarge upon it in this place. 



It lias been noticed, towards the beginning of the 

 present essay, that the principal star of each NucshafrOy 

 is denominated Yogat/irii. Perhaps it may not be su- 

 perfluous to caution the reader against confounding 

 thtstyoga stars with the yogas, of which a list is inserted 

 in Sir W. Jones's Treatise on the Indian Zodiack *. 

 They are mentioned by him as divisions of the eclip- 

 tick : but it will presently appear, that they cannot in 

 strictness be so denominated. Tiieir principal purpose 

 regards astrology ; but they are also employed in regu- 

 lating certain moveable feasts ; and they are of such 

 frequent use, that every Indian Almanack contains a 

 column specifying the yoga for each day, with the hour 

 of its termination. 



The yoga is nothing else than a mode of indicating 

 the «5um of the longitudes of the sun and moon. The 

 rule for its computation, as given in the Silrya Sid- 

 d'^hanta^ Bhds'ivati and Graha laghava^ directs, that the 

 longitude of the sun be added to the longitude of the 

 moon ; and the sum, reduced to minutes, is to |3C 

 divided by 800 (the number of minutes in 13° 20') : 

 the quotient exhibits the elapsed yogas, counted from 

 Vishcumhha ^ . It is obvious therefore, that the j'o^drj 

 are twenty-seven divisions of 360° of a great circle, mea-
