Since the publication of his Lexicon, several others in Greek and English have appeared in England. The example of Germany and the learning of her scholars have contributed to these works. It were to be wished that all of them were free from the imputation of an unhandsome appropriation of labors performed by others. The Lexicon of Dr. Dunbar, Professor of Greek in the University of Edinburgh, published in 1840, contains whole pages taken bodily--"convey, the wise it call"--from that of Mr. Pickering, while the Preface is content with an acknowledgment, in very general terms, of obligation to the work which is copied. This is bad enough. But the second edition, published in 1844, omits acknowledgment altogether; and the Lexicon is welcomed by an elaborate article in the Quarterly Review,[147] as the triumphant labor of Dr. Dunbar, "well known among our Northern classics as a clever man and an acute scholar. _In almost every page_," continues the reviewer, "_we meet with something which bespeaks the pen of a scholar_; and we every now and then stumble on explanations of words and passages, occasionally fanciful, but always sensible, and sometimes ingenious, which amply repay us for the search.... _They prove, moreover, that the Professor is possessed of one quality which we could wish to see more general: he does not see with the eyes of others_; he thinks for himself, and he seems well qualified to do so." Did he not see with the eyes of others? The reviewer hardly supposed that his commendation would reach the production of an American lexicographer. [147] Vol. LXXV. p. 299. In the general department of Languages and Philology his labors were various. Some of the publications already mentioned might be ranged under this head. There are others which remain to be noticed. The earliest is the work generally called _The Vocabulary of Americanisms_, being a collection of words and phrases supposed to be peculiar to the United States, with an Essay on the State of the English Language in this country. This originally appeared in the Memoirs of the American Academy, in 1815, and republished in a separate volume, with corrections and additions, in 1816. It was the author's intention, had his life been spared, to print another edition, with the important gleanings of subsequent observation and study. Undoubtedly this work has exerted a beneficial influence upon the purity of our language. It has promoted careful habits of composition, and, in a certain degree, helped to guard the "well of English undefiled." Some of the words found in this Vocabulary may be traced to ancient sources of authority; but there are many which are beyond question provincial and barbarous, although much used in our common speech,--"_fæx quoque quotidiani sermonis, foeda ac pudenda vitia_."[148] [148] De Oratoribus Dialogus, c. 32,--sometimes attributed to Tacitus.
