crease slightly in relative size, but average 1.05 per cent in the live- 

 born. 



12. The suprarenal glands increase rapidly to a maximum relative 

 size of about .45 per cent of the whole body in the 3d month, de- 

 creasing steadily thereafter to about .24 per cent at birth. 



13. In the case of the paired organs, the larger size of the right 

 lung, left kidney and left suprarenal gland is established early in 

 the fetal period. 



14. At full-term, almost all of the viscera (excepting the thymus 

 and suprarenal glands) average relatively greater in the live-born 

 than in the still-born. 



15. The fetal viscera appear as a rule to be relatively heavier in 

 the female (excepting the thymus, lungs and kidneys).
