Delivered before the University of Oxford, these Lectures were intended to serve a double object. Whilst discussing some points of Slavic and Latin philology, I aimed at illustrating Comparative Lexicography, a sister science of Comparative Grammar, whose formation and uses I have repeatedly endeavoured to advocate.<br><br>A brief account of the existing discrepancy between the two Russian races and languages opens the book. Of the lexicological details given, and the conceptual estimates taken in these introductory chapters, it may be fairly said that they are an attempt at tilling virgin soil.<br><br>An inquiry into Russian, Polish, and Latin synonyms follows. The comparative dissection of a few vocables, indicative of Liberty and Society notions, besides analysing the Slavic mind with the help of the language-test, will, it is hoped, sufficiently demonstrate the method adopted.
