18 THE MODERN MILK PROBLEM 



An important series of observations was made some 

 years ago by Park and Holt, 6 illustrating the effects of 

 feeding infants with several different grades of milk. 

 The deleterious results of bad milk during the summer 

 months are shown by the following table, summarizing 

 the observations on six groups of babies. (The per- 

 centages have been computed by the present writer 

 from the original table.) * 



All cases excluding duplications 421 44% 25% 21% 10% 



In the whiter observations no appreciable difference 

 among the different modes of feeding was noted; what 

 might be considered good results were shown in 93 per 

 cent of the cases as contrasted with the 69 per cent 

 radicated by the above table. 



* This study is open to criticism in certain respects. The small 

 number of cases in the fifth group cannot be taken as a sufficient basis 

 for rating best bottled milk above breast feeding. The number in the 

 breast-fed group is also rather small for the calculation of significant 

 percentages. Nor is distinction between raw and heated milk made 

 in this table. The element of care of the infant (as well as other factors) 

 in the different groups is discussed by the authors as a separate, im- 

 portant consideration taken into account in their conclusions, certain 

 of which are quoted below. There is no doubt but that, were all other 

 things equal, breast feeding would show decidedly the highest rating. 

 The Park and Holt study, while not entirely satisfactory, is here quoted 

 on account of its general illustrative character.
