The current Number of rhambers's Educational course con- tains an
Introduction to the Sciences ; and is the best treatise which has yet appeared in the series. Of course, in a little book extending to no more than one hundred pages, and embracing in its subjects the whole of the material world, both inanimate and animate—from the stars, the solar system, the earth and its phumomena, through the vegetable and animal creation up to man—no more than the general principles and leading outlines of each subject can be given ; but what is done is well done, being complete so far as it goes, and display ing greater maatery of the subject than has jet been exhibited by the writers in the r.ducas
tional Course. We would especially instance, as pieces of able. popular exposition, the chapter on the Attraction and Motion of Matter, and the brief view of the results to which Geology leads,. in the chapter on the Structure the Earth.
