IM. A. de Lapparent, ju-ofessor in tlie Ecole libre de hcmtes etudes in Paris 
and lately jnesident of the French Geographical Society, lays us under 
many oldigations by the iireparation of this valuable work. An accom- 
jilished field geologist, as evinced, for example, in his monograph on the 
peculiar deformation in the Paris basin known as the Pays de Braj’ ; 
author of a compendious treatise on geology, the leading work of its kind 
in the French language ; a presiding otficer as notable for his courteous 
tact as for his competence in his subject, he now discloses a close acrpiaint- 
ance with a line of study that as yet is hardly acclimated in Europe, 
namely, the American science of geomorphology, whose principles and 
name he adopts together. Although his references to American sources 
overweight the relative importance of contributions from certain quarters, 
he has clearly seized the essentials of the rational as against the empirical 
method of geographical description. The initial forms iiroduced by
