The principal object of this paper, was to defend some interpretations of words in the ancient language of Etruria, proposed by Lanzi, and attacked by Niebuhr; as well as to point out some new analogies with other dialects. The languages which the author proposes particularly to call to his assistance are, Greek, Latin, Anglo-Saxon, and Cambrian or Welsh. The paper concluded with an application of these aids to a variety of words in the Etruscan language.
