SYSTEMATIC SYNTHESIS OF TISSUES INTO ORGANS. 217 

 326. To PREVENT DEFORMING PRESSURE UPON THE 



INTERVEHTEBRAL SUBSTANCES, let the clothing be free 

 and easy; occasionally change the position of the body, 

 and frequently take repose in a reclining posture, if the 

 health is delicate. 



327. Remark. WHEN A CHILD, MORE PARTICULARLY A YOUTH, is 

 GROWING rapidly, especially if of light complexion, the cartilages do 

 not as rapidly become firm, nor ought they, for several reasons that will 

 be given under the various heads to which they belong, to sustain the 

 spinal column erect under those circumstances : they will readily yield, 

 and the column appear curved forward about the shoulders. If it does 

 not curve laterally no matter (it seldom will unless badly treated) ; as 

 soon as the child is older and the cartilage hardened, erectness will be 

 regained, if the clothing is not allowed to constrict nor any one position 

 to fatigue him. He should also have much time for reclining repose. 

 If, on the other hand, the clothing is tight, and apparatus worn or injunc- 

 tions laid down, to maintain one position, the cartilages will be sure to 

 yield upon the sides, and unfortunate lateral curvatures will result, that 

 will be with great difficulty, if at all, corrected. Nature, Nature, NATURE, 

 give NATURE play, and she will reward the deference with Htheness of 

 motion, graceful elasticity, and the thousand blessings she is in the 

 habit of bestowing upon her followers. 



Inf. The seats upon which scholars sit should be easy, with backs 

 sloping at a proper angle, while children should also have frequent re- 

 cesses, or stand or move about, nor be required to maintain the same 

 position for an hour at a time. 



328. THE SPINOUS PROCESSES are portions of bone 

 extending from the back point of the arches, being short, 

 inclining downward* a little, in case of the upper seven 

 (very small in case of the upper two), and allowing con- 

 siderable backward motion, longer and inclining down- 

 ward very much in case of the next twelve and allowing 

 but slight backward motion, and in the lowest five ex- 

 tending straight back, short and stout, and allowing 

 extended backward motion ; therefore, 



329. THE VERTEBRAE ARE SUBDIVIDED into Cervical 

 (neck), Dorsal (back), that correspond to the ribs, and 

 of course chest, and the Lumbar (loin).
