 is concerned, it affords little help in discriminating periods within the Rigveda except with regard to the tenth book. For throughout the hymns, in spite of the number of authors, essentially the same language prevails. It is quite possible to distinguish differences of thought, style, and poetical ability, but hardly any differences of dialect. Nevertheless, patient and minute linguistic research, combined with the indications derived from arrangement, metre, and subject-matter, is beginning to yield evidence which may lead to the recognition of chronological strata in the older books of the Rigveda.

Though the aid of MSS. for this early period entirely fails, we yet happily possess for the Rigveda an abundant mass of various readings over 2000 years old. These are contained in the other Vedas, which are largely composed of hymns, stanzas, and lines borrowed from the Rigveda. The other Vedas are, in fact, for the criticism of the Rigveda, what manuscripts are for other literary monuments. We are thus enabled to collate with the text of the Rigveda directly handed down, various readings considerably older than even the testimony of Yāska and of the Prātiçākhyas.

The comparison of the various readings supplied by the later Vedas leads to the conclusion that the text of the Rigveda existed, with comparatively few exceptions, in its present form, and not in a possibly different recension, at the time when the text of the Sāma-veda, the oldest form of the Yajur-veda, and the Atharva-veda was constituted. The number of cases is infinitesimal in which the Rigveda shows a corruption from which the others are free. Thus it appears that
