Malayalam summary of a Sanskrit work under the title Gralhapariks6 krama. The textual verses were not available to the editor and he presumed that the author was Drganita-Parameswara. * These verses are however, found in Nilakantha's Bhasya on the Golapadld of the 2,४५0 blafrya, under verse 48 (7SS 185, pp. 132-49).
