The class-book of anatomy : designed for schools, explanatory of the first principles of human mechanism, as the basis of physical education . show the number of pieceswhich are united into one : the ensiformcartilage, or tip of the sternum, — bent outof place, very frequently, to the great det-riment of the individual, is marked h. Very small children, in schools, become excessivelyweary, after sitting a little time on stiff benches — arcsleepy, and can scarcely be kept awake. This is naturesmode of seeking relief from the pressure and gravity ofthe chest, which is confining both bones and should certainly be permitted, either to have a re-cumbent posture, which is thus indicated, or they shouldbe kept but a very little time in one position. Malforma-tion of the bones, narrow chests, coughs, ending in con-sumptions and death in middle life, beside a multitude ofminor ills, have often had their origin in the school-room.
