Sight and Hearing in Childhood. By R. Brndenell Carter and

Arthur H. Cheatle. (Scientific Press. 2s. net.)—This volume is intended to supplement educational methods. Even now much that is attributed to intellectual torpidity or backwardness is really due to defects of hearing or sight. The child is supposed not to understand when he really does not see or hear, being unable, because unused, it must be remembered, to make good such defect by using other senses. The book is, of course, too technical for detailed examination here, but we strongly recommend it.
