In school, the small children, after sitting a short time, be-come restless. If their position be changed, their imperfectlydeveloped muscles will acquire tone, and will again supportthe spinal column erect without pain. Compelling childrento sit erect for a long time, is an evil practice ; for it is a vio-lation of the muscular law, and too frequently produces thelateral curvature of the spine and projecting shoulder. Fig. In cases of projecting shoulders, as here represented (fig. 87), there ia uniformlycurvature of the spinal column. The necessity of frequent intermissions or recesses in schoolis founded on the organic law of muscular action, alternatingwith rest. The younger and more feeble pupils are, the greater thenecessity for frequent recesses. We would not have theteacher think that one half of the time, at least, should bespent in giving the pupils intermissions ; or the mother, thather daughter is going to school to play. But we maintainthat recesses should be given ; and that they should be short Why should not small children be confined in one position for a longtime ? What evils result from this practice ? What class of pupils shouldhave recesses most frequently ? PltACTICAL SUGGESTIONS. 121 and frequent for small and feeble scholars. If such were thepractice, young misses would not complain of weakness in the6pine and limbs an
