See the work of John Christopher de Jordan, de Originibus Sclavicis, Vindobonae, 1745, in four parts, or two volumes in folio. His collections and researches are useful to elucidate the antiquities of Bohemia and the adjacent countries; but his plan is narrow, his style barbarous, his criticism shallow, and the Aulic counsellor is not free from the prejudices of a Bohemian.
