_Adur_ (Vol. ii., p. 108.).--The connexion of the Welsh _ydwr_ with the
Greek [Greek: hydor] is remarkable. Can any of your readers tell me whether
there be not an older Welsh word for _water_? There are, I know, two sets
of Welsh numerals, of which the later contains many Greek words, but the
older are entirely different. Is not _cader_ akin to [Greek: kathedra], and
_glas_ to [Greek: glaukos]?
