MID-MORNING LUNCH IN RURAL SCHOOLS

The closest relationship found with the "qualitative" nutritional condition 

 was that for muscle tone and for skin color, the coefficients being +.70 and +.69 

 respectively. Somewhat less correlation was shown with the condition of the 

 lungs, amount of subcutaneous tissue, posture, size of lymph glands of the neck, 

 and tonsils, the coefficients ranging from +.55 to +.38. These values would 

 indicate that both muscle tone and skin color are important factors in the evalua- 

 tion of nutritional condition and that the other points mentioned above, while 

 less significant, also contribute more or less to the picture. Some significance 

 may also probably be attached to the color of the mucous membrane (lining of 

 the mouth), though a value of but +.30 for r would indicate that it is not great. 

 The coefficients obtained for bodily repose, heart, color of lips, conjunctivae, and 

 muscle coordination are too low to indicate the existence of any significant corre- 

 lation with status of nutrition.

 showing that children may have normal lungs irrespective of their nutritional condition, but that 

 children with poor lungs were rarely in good nutritional condition.
