ANSWERS 



TO THE 



QUESTIONS 



IN THE 



HYGIENIC PHYSIOLOGY. 



23 ! Why does not a fall hurt a child as much as it 

 does a grown person ? 



The bones of a child are largely cartilaginous, and so do not 

 transmit a shock, or readily yield to a blow. They are also well 

 padded with fat. 



2. Should a young child ever be urged to stand or 

 walk? 



No ; bow-legs are often caused by the premature use of the 

 lower limbs in standing or walking. Nature is the best guide 

 in such matters. 



3. What is meant by " breaking one's neck " ? 



The dislocation of the vertebrae and consequent injury of 

 the spinal cord. 



4. Should chairs or benches have straight backs ? 



The backs should conform to the natural shape of the spine. 

 This tends to prevent curvatures and other distortions of the 

 vertebral column. 



5. Should a child's feet be allowed to dangle from a 

 high seat ? 



The position is as unnatural and painful for a child as for a 

 grown person. 



6. Why can ^ve tett whether a fowl is young by pressing 

 on the point of the breast-bone ?
