The GaRic Dictionary is a valuable addition to our stock

of philological lore. Before we can become thoroughly acquainted with the vestiges which still remain of our ancestors, and yet form the rudiments of our history, we must collect and compare all traces of language. Language • is the principal and most un- erring guide in the investigation of the origin and affiliation of nations. The practical use of a Gaelic Dictionary will only be felt where .Gaelic is spoken, but the philological uses of this work may. be great all over ".Prydain." It appears (for we cannot speak with certainty) to be completed with great industry and intel- ligence ; and does honour to the authors, Dr. M`LEon and Dr. DEWAR, and to their patrons and assistants in the arduous undertaking.
