in detail belonging to the older period, the text maintained a remarkably high level of authenticity till such modifications as it had undergone reached their conclusion in the Saṃhitā text. This text differs in hundreds of places from that of the composers of the hymns; but its actual words are nearly always the same as those used by the ancient seers. Thus there would be no uncertainty as to whether the right word, for instance, was sumnam or dyumnam. The difference lies almost entirely in the phonetic changes which the words have undergone according to the rules of Sandhi prevailing in the classical language. Thus what was formerly pronounced as tuaṃ hi agne now appears as tvaṃ hy agne. The modernisation of the text thereby produced is, however, only partial, and is often inconsistently applied. The euphonic combinations introduced in the Saṃhitā text have interfered with the metre. Hence by reading according to the latter the older text can be restored. At the same time the Saṃhitā text has preserved the smallest minutiæ of detail most liable to corruption, and the slightest difference in the matter of accent and alternative forms, which might have been removed with the greatest ease. Such points furnish an additional proof that the extreme care with which the verbal integrity of the text was guarded goes back to the earlier period itself. Excepting single mistakes of tradition in the first, and those due to grammatical theories in the second period, the old text of the Rigveda thus shows itself to have been preserved from a very remote antiquity with marvellous accuracy even in the smallest details.
From the explanatory discussions of the Brāhmaṇas in connection with the Rigveda, it results that the text
