In the Berlin collection of Sanskrit literary remains from Chinese Turkestan there is a manuscript, catalogue-number S 474, which has been identified by me in a preliminary report1 as containing the text of the first 25 Sūtras of the Nidānasamyukta, one of the most important parts of the Sanskrit Saṃyuktāgama which corresponds to the Saṃyuttanikāya, the ‘Collection of Grouped Discourses’, in Pāli. The greater part of the first 19 leaves of the manuscript has been preserved. The script is of the older Central Asian Brahml type, and the folios, as far as they are complete, are unusually large (13 × 52 cm.).
