A. Borrowed from Pandit A Hindu scholar or learned master of Sanskrit. Rájájí, of Benares : venerable in appearance, and almost without an error ; but defective, in the first part, by the whole of the opening chapter and about half of the second.

B. Belonging to Traváḍí Lajjás'ankara Pandit, of Benares : generally correct.

D. Likewise from the library of the Asiatic Society of Bengal, being No. 77 : almost useless : in the same character with C.

a. It belongs to Pandit Náráyaṇa Bhaṭṭa, of Benares : moderately correct.

b. Procured from Traváḍí Lajjás'ankara Pandit, of Benares : much more faulty in the first part than in the second.

c. A MS. belonging to the Asiatic Society of Bengal, being No. 81 : in the first part, nearly related to the corresponding portion of b ; in the latter, wanting all the thirteenth chapter but its beginning and end : of scarcely any worth : in the Bangálí character.

d. Lent to me by Paṇḍyá Indrají Durlabhají, of Benares : contains only the first part ; and of thus much the seventh and
