Leverett Frederick P. (ed.) A New and Copious Lexicon of the Latin Language

Enlarged and improved edition. — Philadelphia: J.B. Lippincott, 1850. — 1348 p.Compiled chiefly from the magnum Totius latinitatis lexicon of Facciolati and Forcellini, and the German works of Scheller and Luenemann.The present edition of Leverett’s Lexicon will be found to be much improved by the transfer to its columns of the classical distinctions of the words from the Lexicon of Dr William Freund, of Germany. The classical character of the words is marked by placing a figure directlv under the first letter of the word in its column; except that where there 's not room for tms, the figure is generally inserted at or near the end of the line.
A word with no figure under it, is Classical, and fully Ciceronian, or else it is s proper name, to which classic laws do not apply.
The figure 1, placed under a word, denotes that it is rare in Cicero. These words are Classical, but not of the first authority ; though many of them are peculiar to that writer.
The figure 2, placed under a word, denotes that it is Classical, but not Ciceronian. The classical prose writers are Cicero, Caesar, Sallust, Livy, Velleius, Celsus, the two Senecas, Quintilian, Tacitus, Suetonius, Pliny the elder, and Pliny the younger.
The figure 3, placed under a word, denotes that it does not belong to classical, prose. Some of these words are Ante-Classical, and some of them are occasionally found in the Poets; but most of them are Post-Classical, belonging to Low Latin, Ecclesiastical Latin Medieval Latin, and many of them to the New or Modern Latin, coined chiefly for the convenience of the sciences.
While transferring the above notes and marks, a catalogue was very carefully made out, of all the words in each Lexicon, which are not found in the other. On c omparing these catalogues, it was found that the number of additional words in each Lex con is nearly equal; the difference being sometimes in favor of the one, and sometimes of t e other. But the value and importance of the additional words found n Leverett, so far as a knowledge of the Latin language is concerned, very far exceeds that of those found in Freund , the distinction in favor of the former consisting chiefly in Latin words found in good, and often in classical writers ; and the distinction in favor of the latter consisting chiefly in New or Modern Latin Scientific Terms, and Proper Names.
