We congratulate the lovers of history and of physical geography, as well as all those who are interested in the growth and expansion of our common education, that Prof. Guyot contemplates the publication of a series of elementary works on Physical Geography, in which these two great branches of study which God has so closely joined together, will not, we trust, be put asunder."--_Christian Examiner._ "A copy of this volume reached us at too late an hour for an extended notice. The work is one of high merit, exhibiting a wide range of knowledge, great research, and a philosophical spirit of investigation. Its perusal will well repay the most learned in such subjects, and give new views to all, of man's relation to the globe he inhabits."--_Silliman's Journal, July, 1849._ "These lectures form one of the most valuable contributions to geographical science that has ever been published in this country. They invest the study of geography with an interest which will, we doubt not, surprise and delight many. They will open an entire new world to most readers, and will be found an invaluable aid to the teacher and student of geography."--_Evening Traveller._ "We venture to pronounce this one of the most interesting and instructive books which have come from the American press for many a month. The science of which it treats is comparatively of recent origin, but it is of great importance, not only on Recount of its connections with other branches of knowledge, but for its bearing upon many of the interests of society. In these lectures it is relieved of statistical details, and presented only in its grandest features. It thus not only places before us most instructive facts relating to the condition of the earth, but also awakens within us a stronger sympathy with the beings that inhabit it, and a profounder reverence for the beneficent Creator who formed it, and of whose character it is a manifestation and expression. They abound with the richest interest and instruction to every intelligent reader, and especially fitted to awaken enthusiasm and delight in all who are devoted to the study either of natural science or the history of mankind."--_Providence Journal._ "Geography is here presented under a new and attractive phase; it is no longer v dry description of the features of the earth's surface. The influence of soil scenery and climate upon character, has not yet received the consideration due to it from historians and philosophers. In the volume before us the profound investigations of Humboldt, Ritter and others, in Physical Geography, are presented in a popular form, and with the clearness and vivacity so characteristic of French treatises on science. The work should be introduced into our higher schools."--_The Independent, New York._ "Geography is here made to assume a dignity, not heretofore attached to it. The knowledge communicated in these Lectures is curious, unexpected, absorbing."--_Christian Mirror, Portland._
