Paris, A la Tour de Babel, 1844. 4to (28.1 x 22.5 cm), 156 pp. Contemporary half morocco over marbled boards. Spine with five raised bands bordered by gilt lines. Red morocco label with gilt title. Marbled endpapers.

The rare quarto edition. In this work De Gembloux developed his theory that before the Deluge human beings and animals spoke the same language. After the biblical flood, animals kept their way of expression while mankind expanded his. Some very light foxing to the text pages. Otherwise, a very nice and clean copy in an attractive binding and with unusually broad margins.
