We shall find unequivocal proofs that this word also was used by the old Celts of Gaul, as in “_Boulogne_,” i.e. Bala (Beal, or Buel) Liane, “The mouth of the Liane.” The town is at the mouth of a small stream, of which Bullet, who does not appear to have suspected the derivation, says “La rivière qui passe à Boulogne s’appelle _Liane_.—The stream that runs by Boulogne is called Liane!” “Liane, Lune,” &c. is a common proper name for a stream in all countries of which the Celts formed the first population. Lliant (Llian-au, _plur._) means a stream, a torrent, in Welsh; Llyn, “Water,” in Welsh; and Lean, Irish. Hence “The Lune” in Herefordshire, &c. ‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ A further example of words of this Class occurs in the Latin name of the “Humber.” This great receptacle of streams was generally called Ab-us; but Ptolomey, in Greek, gives the name more fully, “Abontrus!”(63) This word means in Welsh and Irish “The Outlet”, or literally “The Door” of the Rivers. Trus, A Door, (Drous, _Welsh_, Doros, _Irish_,) occurs in the same sense in Tura (_Sanscrit_), Der (_Persian_). Hence it appears that the Welsh word, which is nearer to the term preserved in this name, has not been borrowed from the English “Door!” ‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ “Aber,” however, was the greatest favorite with the ancient Celts, as with the modern Cymry! It would seem that this word “Aber” was as commonly applied in ancient Gaul, &c. as it still is in Wales, not merely to the mouths of large rivers, but to places situated at those of _very small streams_!(64) ‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ _Britain._—York, Ebor-acum (Caer Eboranch, _Welsh_; Ever-wick, _Saxon_.) Is inclosed for the most part between the Ouse and the Foss, which unite close to the Town! The river Foss separates _some parts of the Town_ from the rest. Eburo-cass-um (Alnewick), at the mouth of the River Alne, Northumberland. Ever-wick is the name of an adjoining Village on the same river. Eburo-nes (_Belgic. Gaul_). About the junction of the Saba and the Mosa. Cæsar states in his account of them that this tribe had no Town. There was a prince of the Œduans(65) in Cæsar’s time, named Eporo-dor-ix, apparently from Aber-Dour “Water,” and Rex. The Gaulish chiefs, like those of the Gaelic Scotch, seem to have frequently derived their names from their peculiar territories or patrimonies; in the same manner, for instance, as the chiefs “Lochiel, Glengarry,” &c.
