-vicas [Ordo-vices, Zemo-vlces, IvishficJi] = Rittavveccas 69, Rittavvecc 100, 

 Denaveca 220, but Catuvviq ... 36, Ercavicca 62, Calunovica 214. 



10. The diphthongs ai, oi, in this position become de, 6e} Hence in the 

 Ogham period, it is probable that the values were ai, 6i. This is also the 

 customary notation in 0. I., and the modern duplicates caorthann, cdrtJiann, 



forhhfaoilteach, fdilte bear the same evidence. So we have the non-diph- 

 thongal spellings Neta Vroqi 239, CoUabota 212,^ beside Vraicci (Vroicci ?), J, 

 1898, p. 230, and Netta Vrocic[i], J, 1903, p. 76, CoiUaMotas 79 (= Nat Froich, 

 Coelhoth). I hesitate to believe that the simple o here stands for the 

 diphthongal sound oi. Much less is it credible that Niott Vrecc 93 is a 

 mere variant of 239, as Macalister thinks. It is more reasonable to regard 

 as a dialect variant of 5i. 



Coimagni 22, 140 = Coemdn, mod. Caomhdn. 



Mailagni 17, 155 = Mdcldn, mod. Maoldn. 



*Maila nom, (gen. Maile Inbiri 38, Mail' Aguro 163,) = Mdel, mod. maol. 



*vroicas, nom. =fr6cch mod. fraocJi. 



coila = coel, mod. caol. 



Laidann (?) 2, perhaps Baidann (the first letter was read by touch, being 

 out of sight) for *Baidagiii = Baetdn, mod. Baoddn, 



11. Before u, a becomes av.y later u. 

 Mail' Aguro 163 = Mdel Augro, Mdel Ugra. 

 magu 213, nom. or dat. of *inagus = riiavg, nwg. 

 Calunovica 214, cf. Culann, Cu Cliulaiwn? 



But this change is usual only when a liquid or an aspirate media inter- 

 venes. Thus catu- = catli, and so in the compounds Donnchad, etc. 



12. Before u, o becomes u. 



Vuroddran 72, Vuruddrann (Macalister i, p. 15), = *vor-udra-gni Fiiru- 

 dran AU. 



13. Before u, e becomes i. 



niotta 71, niott 93 = *ne[p)utas, Latin nepdtis ^-^aioth L. Arm. 



Meddugeni 176 = nom. Midgen or Midgna. 



Veducuri 175 = Fidchioire (Ciarraige and other genealogies). 



14. The consonant v exercises the vocalic mfluence of u : avi = aid, 

 Dovatuci = Dubthaig, Dovalesci = Duibhisc. 



15. Before i or e, o becomes u. 

 Dovvinias 13, Dovinia 31, 32 = Duibne.
