ADDENDA ET CORRIGENDA.

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.
Russia.	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.

P. [85].

I apprehend that in the opinion of Celtic scholars of the present day the Ancient British deity Cocidis is not considered to have any connection with the river Coquet.

P. [91].

It seems probable that the word asp in river-names is formed by metathesis from the word aps, p. [27], form 5.

P. [97].

The Gryffe and the Girvan may perhaps be better derived from the Gael. grib, swift.

P. [132].

To the root pad or pand, to spread, may probably be placed—

England.

The Pant. Essex.

P. [135].

From the root tan, may be derived the Dniester, (=Danaster), from ster, river. Or it might be from the root dan, as in Danube, p. [116].

P. [136].

The Dan. tang, sea-weed, does not seem to be connected with any word signifying water: it represents the Old Norse tag, twig.

P. [145].

To the root vind, white, clear, place—

England.

The Wente. Yorkshire.

P. [149].

To the Sansc. taras, Welsh têr, pure, clear, place—

Thrace.

Tearus ant.
