SIDDHANTA-SEKHARA of the existence of Sripati's Siddhanta-Sekhara and his Pit gorithm and Vijagarithm, had only to be derived from stray references in extant works or commentaries. Its discovery after so many centuries will no doubt be hailed with telight by those interested in Indian Astronomy and Mathematics The credit of the restoration belongs, indeed, to the late Justice Sir Asutosh Mookerjee, of sacred memory, who was for rnany years the Vice-Chancellor of the Calcutta , University and President of the Council of Post-Graduate Teaching in Arts Under his able direction an extensive search was made in Central and South India for the treatises on Indian Astronomy and Mathematics , such as Suba Sutra, Jgoutise, etc. After a fruitless attempt at Indore, Ujjain, Baroda, Bombay, Poona, Kolhapur, Bangalore, Mysore and Cochin, a copy of Sripati’s siddhant-sehra was at last procured from the State Sanskrit Library of Trivandrumthrough the kind assistance of the late Mahamahopadhyaya, Pandit (Ganapati Shastri, the renowned Editor of Bhasa's Dramas and Kautilya's Artha•Sastha, and Mr. K. V. Rangaswami Iyengar, M.A., the distinguished Professor of History in the Irivandrum College This treatise. on the theory of Astronomy (Siddhite, as distinguished from Karabad, a practical manual for astronornical calculations) was found complete in 20 chapters, comprising 895 Slokas. On account, however, of certain lacunae here and there, the copy hardly proved sufficient for an authentic edition of the work. The search had to be further continued in Madura, Trichinopoly, Tanjore, Kumbhakonam and Maidyas In the Government Oriental Manuscripts Library at Madras, a Commentary by one Makki Bhatta, called Gitablisat was discovered. Arrangements were made for the transcribing of the manuscript from the provincial script into Devaligg)" , copies being received in instalments . Immediately on the arrival of the first instalment, the editing of the work was taken in hand Pandit Babua Misra, Jyautisबृcfiryya, ९ / ??e!
