separate manuscripts are in fact parts of Sabda nusasana. Attempts hac been made to prove this work to be by the Vedic Sakatayana referred to by Vaska and Panini. Mr. G.

(1) Amoghavitti by the author himself. (2) Nyasa by Prabhachandra. (3) Chintamanitika by Yakshavarna. (4) Maniprakaśikā by Ajitasenācharya. (5) Viitti by Bhavascna Traividva. (6) Rúpasiddhi by Dayāpāla.
(7 Prakriyāsanigraha by Ahhayachandra. 01 these the third and the seventh are among Karanja manuscripts. Yakshavarna also calls his work Sampurnalakshapavritti. In extent it is equal to6,000 Slokas.
