is to be found about them in the most ordinary books — Hallam, Warton, Turner, Palgrave, Wright, etc. — is diligently repeated. The vulgar practice of reading the books one is to write about was beneath so great a philosopher. He has read about them, but very little in them. They could not greatly attract him ; for the Middle Ages must be a mere blank to one who writes the history of modern civilisation without taking into account the two elements of which it is chiefly composed — the civilisation of antiquity, and the Christian religion. Having to utter a few generalities upon the subject, it was obviously more convenient to know nothing about it, and to take counsel of a few writers who knew very little about it, than to run the risk of finding an imprudent curiosity rewarded by the unexpected discovery of unpalatable and inflexible facts. This safe and timely ignorance, which he has discreetly cherished and preserved, has made him fully competent to declare "that not only was no history written before the end of the sixteenth century, but that the state of society was such as to make it impossible for one to be written" (p. 299).
Agreeably to the materialistic character of his philosophy, Mr. Buckle examines with special predilection the physical causes which influence mankind. His second chapter, which is devoted to this inquiry, is the most interesting and elaborate part of the volume. In these regions he is somewhat more at home.

The subject here treated has very recently been raised to the dignity of a separate and distinct science ; and it has been cultivated on the Continent with extraordinary zeal and success. In no department was so much assistance to be derived from contemporary writers. Ritter, the founder of the science of comparative geography, began forty years ago the great work of which he has not yet finished even the Asiatic portion. He was the first among the moderns to determine in detail
