We might pursue the subject still further, and enquire whether the secondary forms, such as _sar_, _sal_, _car_, _cal_, all having the same general meaning, to move, to go, may not be formed, by the prefix of a consonant, on the roots _ar_ and _al_, and so also be ultimately referred to the simple root _î_ or _â_. As also the silent and ceaseless flow of water is the most natural and the most common emblem of the efflux of time; so in the same root is to be found the origin of many of the words which mean time and eternity. The Gr. αει, the Goth. _aiv_, the Anglo-Sax. _awa_, Eng. _ever_ and _aye_, are all from this same root, so widely spread in river-names, and express the same idea which speaks-- "For men may come, and men may go, But I go on for ever." ADDENDA ET CORRIGENDA. P. 25. To the root _ab_ or _ap_, water, place the Lith. and Lett. _uppe_, river, whence the following. _Germany._ The OPPA in Silesia. _Russia._ The UPA. Joins the Oka. The UFA. Joins the Bielaya. P. 33. To the root _ud_ place as an appellative the Obs. Gael. _ad_, water. And add to form No. 1 the following names. _Russia._ The UDA. Gov. Kharkov. _France._ The ODDE. Dep. Allier. P. 35. The Celt. word _and_ or _ant_, water, is nothing more than a strengthening of the above Obs. Gael. _ad_. P. 40. In referring to the root _ark_, _erk_, I have omitted the Ir. _earc_, water, the appellative most nearly concerned. The Basque _erreca_, brook, might be taken to be borrowed from the Celtic, did we not find in the same language the more primitive words _ur_ and _errio_, p. 38, which seem to form a link with the Indo-European languages. P. 49. To the root _nig_, _ni_, place-- 1. _France._ The NÉ. Joins the Charente. _Norway._ The NIA. Stift Trondjem. 3. _With the ending es._ _Russia._ The NERUSSA. Gov. Orel. P. 63. To the root _wig_, _wic_, _wy_, place the two following names. The Welsh _gwy_, water, is the word most nearly concerned in most of the group. _England._ The WYCK. Buckinghamshire. _Russia._ The UI. Gov. Orenburg. P. 64. To the root _vip_ place as an appellative the Welsh _gwibio_, to rove, wander, _gwibiau_, serpentine course. Probably upon the whole the sense of tortuousness is that which should be recognized. The following name probably belongs to form No. 1. _Spain._ The QUIPAR. Joins the Segura. P. 70. The Celtic languages have a trace of the word _trag_, to run, in the Old Ir. _traig_, foot (_Zeuss, Gramm. Celt._) P. 83. For _Greece._ PYDARAS ant. Thrace. Read _Thrace._ PYDARAS ant. P. 84. To the Ir. _biol_, _buol_, water, place the following names. _England._ The BEAULIEU, also called the Exe, in Hampshire. _Scotland._ The BEAULY. Inverness. _Italy._ PAULO ant., now the Paglione.
