tractions made in the latter. Moreover, the old part of the Brāhmaṇa literature shows hardly any traces of speculations about phonetic questions connected with the Vedic text. The conclusion may therefore be drawn that the Saṃhitā text did not come into existence till after the completion of the Brāhmaṇas. With regard to the Āraṇyakas and Upanishads, which form supplements to the Brāhmaṇas, the case is different. These works not only mention technical grammatical terms for certain groups of letters, but contain detailed doctrines about the phonetic treatment of the Vedic text. Here, too, occur for the first time the names of certain theological grammarians, headed by Çākalya and Māṇḍūkeya, who are also recognised as authorities in the Prātiçākhyas. The Āraṇyakas and Upanishads accordingly form a transition, with reference to the treatment of grammatical questions, between the age of the Brāhmaṇas and that of Yāska and the Prātiçākhyas. The Saṃhitā text must have been created in this intermediate period, say about 600 B.C.
This work being completed, extraordinary precautions soon began to be taken to guard the canonical text thus fixed against the possibility of any change or loss. The result has been its preservation with a faithfulness unique in literary history. The first step taken in this direction was the constitution of the Pada, or "word" text, which being an analysis of the Saṃhitā, gives each separate word in its independent form, and thus to a considerable extent restores the Saṃhitā text to an older stage. That the Pada text was not quite contemporaneous in origin with the other is shown by its containing some undoubted misinterpretations and misunderstandings. Its composition can, however, only be separated by a
