I still have a letter from the late M. Bergaigne, in which he asks when my Index would be published, and adds: “Je m’étais décidé pendant ces vacances à écrire tout le Rig-Véda sur des fiches, et à me composer ainsi un index qui pût me permettre des essais d’interprétation indépendante. Je suis arrivé à la moitié de ce travail, et grâce à la rapidité que je suis parvenu à atteindre, et aussi à une grande puissance de travail, je puis le terminer en moins d’un mois ... S’il n’était pas trop exiger, je vous prierais de me dire aussi si vous citez tous les emplois de chaque mot _sans aucune exception_, ou si vous êtes départi de cette rigueur pour les mots très usuels, et enfin si vous adoptez l’ordre alphabétique pur et simple.” I could answer all these questions in the affirmative. Footnote 14: Giuseppe Turrini, _Raccolta degli Inni del Vèda_, Libro I, Fascicolo I, Bologna, 1899. Footnote 15: Rig-Veda X, 39, 1. Footnote 16: Rig-Veda III, 29, 6. Footnote 17: Rig-Veda III, 20, 1. Footnote 18: Rig-Veda I, 116, 17. Footnote 19: Rig-Veda X, 39, 12. Footnote 20: Dawn. Footnote 21: The cloud. Footnote 22: Name of the Dawn. It requires a considerable acquaintance with phonetic laws to doubt the identity of the names Ushas in Sanskrit and Eos in Greek. Yet I believe that even this has been achieved by those who seem to imagine that scepticism is the best proof of knowledge. Footnote 23: Savit_ri_, the sun-god, but distinct from Sûrya, the sun and sun-god. Footnote 24: Name of Dawn. Footnote 25: Day and Night, Dawn and Twilight are conceived as sisters, and spoken of as Ahanî, the two days, one bright, the other dark, like the A_s_vins. Footnote 26: Varu_n_a, sometimes the highest god, whose laws have to be obeyed by all creatures. Footnote 27: Their appointed course. Footnote 28: Kratu, thought, will, here command. Footnote 29: The order in which the heavenly bodies come and go, which gave the first intimation of order in the universe. Footnote 30: The sun. Footnote 31: Dawn is often spoken of in the plural, being conceived as new every day, or being considered manifold in her wide expanse. Footnote 32: Perhaps it should be remembered that in the Mahâbhârata the wife of Ka_s_yapa, the mother of the Âdityas, was called Dakshâya_n_î; see Pramatha Nâth Mullick, “Origin of Caste,” p. 33. Footnote 33: Cf. “Chips,” IV, p. 385. Footnote 34: The two words are used together, as ubhayor antara_m_ veda, sûn_ri_tân_ri_tayor api, Mahâbh. V, 5667. Footnote 35: Agni, fire, is here, as often, taken for the light of day. Footnote 36: Mitra and Varu_n_a stand for morning and evening, or day and night. Footnote 37: Râtrî, night, sometimes called the black day, Kr_i_sh_n_am ahar, opposed to Ar_g_unam ahar, the bright day. Cf. Rig-Veda VI, 9, 1. Footnote 38: Evil, physically darkness, morally sin. Footnote 39:
