Sign-Stahaka together constitute Abhijit : it is so to be accounted when twenty-eigh asterisms are reckoned; not otherwise. ’’ Ordinarily, however, the division of bha ecliptie into twenty-seven equal portions jamnade. and Abhijit i8 Sumply passed by in her distribution . After the introduction of the modern method of dividing the circle 2nto aegrees and minutes, bbas last way of setting the difficulty womuld bviously receive a powerful support, Rढून an inereased eurreney, from the fact that a division by twanty-seven gove each portion on even mber of thimates, 800, while a division by twenty-eigh{ ¥1¢lder the | 3 }' and uranageal le quoten6 1; Much yet terrains to bः ne, lbefore the history nn 1st of the system of asterisms, as a prt of the ancient Hindu astronomy and astrong, shall be fully understood 'here as n exist(net an abudant literature, ancient and moderm, upon the subject, which will doubtlex aft some time provoke laborious investigation, anti peppy at with interesting results 'To us hardly any of that literature ack¢ble, mid mly the final results of wids. 0xtended and longkntinue studie५ upon it could be in place here.
