B. No. C. 809-C [1] of the above Library, unidentified and uncatalogued, and written in continuation of the Sphatanirnaya with commentary (No. C. 809-C), described under Text Ms. B, above.

Appendix IV. Parahitåt Sphutanirņaya-tulya-madhyamádnayanaya Gunakaraharakah. As the longish title given to the work on the basis of the subject would indicate, this tract enunciates the multipliers and divisors for the derivation, using the astronomical constants of the Parahita system of Kerala astronomy, of the Mean Planets as accurate as those computed according to the Sphutanirnaya. Periodical corrections of the multipliers and divisors are also recommended once in 1000 days in order to maintain the accuracy of the computed results. While the work does not mention the name of its author, it is possible to suggest Puradahanapura-dvija (Mal. Purayannir Namputiri) of the 19th century A.D. as the author, on the basis of certain characteristics that exist between this work and certain other works of this author occurring in the same codex.
The edition is based on Ms. Jy. 568 (Q) of the Govt. Sanskrit College Library, Tripurnithura, described under Appendix II. This work which had not been identified there, occurs, on folios 33b (line 3) to 34a (line 3). The text preserved is error-free.
Appendix V. Sphutanirņayatulya-grahamadhyamāna yanam, in ten verses, is a short tract on the computation of the Mean Planets. The numerical figures of the Sphutanirnaya have all been converted to the katapayadi notation. In addition to what is given in the Sphutanirnaya, the present work supplies the zero-positions of the planets at the advent of Kali and also mentions a contemporary date (khanda-dina), with the zero-corrections (dhruva-s) therefor, in order to facilitate the computation of the Means. In a very interesting
