MS. B1 which calls it Upanidāna is the oldest, as far as I know, of all the dated MSS. of the work.
Though Bi calls it merely Upanidāna, I have named it Upanidāna-sūtra because it is really in the Sūtra style.
As regards the nature of the work, it is obviously of the same type as the Anukramaņi literature of the other Vedas. Like the Rgvedic Chandonukramaņi of Slaunaka, it also aims at giving an Anukramaņi of the metres of the Sāmaveda-samhitā, with the only difference that like the Sarvānukramaņis of Kātyāyana it also gives, in the first three chapters, a general outline of the Vedic metres and that chapter VIII is also of a general character, V. CONTENTS AND SCOPE OF THE WORK,
As already stated, the first three chapters of the Upanidāna- sūtra are of a general character. The first chapter gives the names of the seven Ārsa inetres, describes their nature and details their varieties,
The second chapter deals with the defective and Aticchandas metres, and describes the method of determining the real nature of doubtful metres aud other allied matter.
The third chapter deals with the Daiva, Asura and Prājāpatya metres on the one hand, and those of Yajuḥ, Sānan and Ry ou the other.
Chapters IV tu VII form the nucleus of the book and deal with the metres of the Simavella--samhita iu detail as follows:--
