_Ireland._ The BOYNE. _Germany._ BUN(AHA), 9th cent., now the BAUN(ACH). From the Ir. _biol_, _buol_, I derive the following, keeping out the rivers of the Slavonic districts, which may be referred to the Slav. _biala_, white. 1. _England._ The BEELA. Westmoreland. _Ireland._ The BOYLE, of which, according to O'Brien, the Irish form is BUIL. _France._ The BOL(BEC). Dep. Seine-Inf. _Germany._ BOLL(AHA) ant. Not identified. _Asia Minor._ BILLÆUS ant., now the Filyas. 2. _With the ending er._ _Germany._ The BUHLER. Wirtemberg. _Russia._ The BULLER. 3. _With the ending et._ _Germany._ The BULLOT. Baden. _Russia._ The POLOTA. Joins the Dwina. A very obscure root in river-names is _gog_ or _cock_. The only appellatives I find are in the Celtic, viz., Gael. _caochan_, a small stream, Arm. _goagen_, wave; unless we think also of the word _jokk_, _jöggi_, which in the Finnic dialects signifies a river; and in that case the most probable root would be the Sansc. _yug_, to gush forth. To the river Coquet, in Northumberland, something of a sacred character seems to have been ascribed; an altar having been discovered bearing the inscription "Deo Cocidi," and supposed to have been dedicated to the genius of that river. Again, we are reminded of the Cocytus in Greece, a tributary of the river Acheron, invested with so many mysterious terrors as supposed to be under the dominion of the King of Hades. Possibly, however, it might only be the similarity, or identity, of the names which transferred to the one something of the superstitious reverence paid to the other. At all events, I can find nothing in the etymology to bear out such a meaning. 1. _England._ COCBRÔC (_Cod. Dip._) This would seem to have probably been a small stream called Cock, to which, as in many other cases, the Saxons added the word brook. 2. _Germany._ COCHIN(AHA), 8th cent., now the KOCHER.[33] 3. _With the ending er._ _England._ The COCKER. Cumberland. The COKER. Lancashire. _India._ The KOHARY--here? 4. _With the ending el._ _Transylvania._ The KOKEL, two rivers. _England._ COCKLEY-BECK.[34] Cumberland. _Germany._ CHUCHILIBACH, now Kuchelbach. 5. _With the ending et._ _England._ The COQUET. Northumberland. _Greece._ COCYTUS ant., now the Vuvo. 6. _In a compound form._ _England._ The CUCKMARE, Sussex, with the word _mar_, p. 61.
