SUPPLEMENT TO OUTLINES.
1. cf. Grierson's Linguistic Survey of India as to how far the statement is to be limited as embracing India. Concerning Asia the statement is to be restricted to living Aryan languages.
2. v. J. Hoop's Waldbäume und Kulturpflanzen (Trübner, 1905), pp. 113-114, 382-384. The question is far from being settled.
3. cf. G. Dottin: Les désinences verbules en r en Sanskrit en italique et en celtique. He regards the passive in r in Celtic and Italic as an independent creation, the common element r going back to the period of Indo-European unity. Even the future in -bo he regards as a possibly analogous formation and different in origin and development. Compare critique in Revue Celtique, 18, 343, where M. D'Arbois de Jubainville takes exception to some points. Irish, contrary to the Latin, has conserved the Indo-European perfect. Further, see G. J. Ascoli: Osservazioni fonologiche concernenti il celtico e il neolatino in Actes du dixième congres international des Orientalistes ii. ème partie, Leide Brill, 1895; cf. Indogerm. Forschungen Anzieger vii., i., 70. Also Windisch in Grundriss der Rom. Philologie, where most of the relative literature is summarized and discussed. The views of M. D'Arbois were made accessible some years ago in a paper in the Celtic Magazine, ed. by Dr MacBain. cf. Giles's Manual § 449.
4. cf. Rhys's Celtae and Galli in Proceedings of the British Academy. Dr MacBain's notices of it in the Scottish Historical Review and in the Celtic Review are of interest, as also Sir J. Rhys's references in his Celtic Inscriptions of France and Italy, reviewed by the writer in the Scottish Historical Review, July, 1908.
5. See Stokes on Pictish and Other Names in Bezzenberger's Beiträge, Band 18. In the second edition of Skene's Highlanders of Scotland, Dr MacBain clearly summarizes the whole of the Pictish problem. Dr Zimmer's views were made accessible in a paper treating of Matriarchy Among the Picts given in the writer's Leabhar Nan Gleann (Edin.: N. Macleod).
6. See Old Celtic Inscriptions by Stokes in Bezzenberger's Beiträge, B. xi., 112-141; Rhys's Celtic Inscriptions of France and Italy, and reviews by Thurneysen in Zeitschrift für Celtische Philologie.
