But, one thing more: Is your child inclined to pore over its books _too much_? Be careful, lest its mind be over-stimulated at the expense of the body. Many a child is at this hour undermining its physical constitution by reading in the house, when it should be playing out of doors, or using its muscular system in some kind of domestic employment. Beware of any cause which shall induce a sickly precocity or a hotbed mental growth. Let no partiality for mental prodigies induce you to make _physical invalids_. The sacrifice is too great; seek rather a healthy and complete development of the whole child, watching each power as it unfolds, and training all for the most efficient fulfillment of the practical duties of life. * * * * * NOTICES OF BOOKS. We venture to devote more space than usual to "Notices of Books," as we have a large number on our table deserving a word of commendation. We shall confine ourselves to the class of works of which the topics of consideration come within the scope of this magazine. MEMOIRS OF THE LIFE AND TRIALS OF A YOUTHFUL CHRISTIAN, in Pursuit of Health, as developed in the Biography of NATHANIEL CHEEVER, M.D. By Rev. HENRY T. CHEEVER. With an Introduction by Rev. GEORGE B. CHEEVER, D.D. New York: Charles Scribner. We have laid down this book, after attentive perusal, with the feeling that among the many things to be learned from it, one stands prominently forth,--_the beauty of family affection in a Christian household_. "To our _Beloved_ and _Honored_ MOTHER, these Memorials of her Youngest Son are affectionately Dedicated." Here we stand at the foundation stone, and are not surprised afterward to see taking their place in the fair edifice of family love, "stones polished after the similitude of a palace."
