MILK AND ITS HYGIENIC RELATIONS 



The results of the second method are shown in Table IV, and 

 have been plotted on Diagram 10, p. 200, which shows that as regards 

 rate of growth there is little to choose between the two series. The 

 babies fed upon boiled cow's milk doubled their weight at the 185-192116. 

 day, or a fortnight earlier than the breast-fed babies, but they started 

 with an initially lower weight, since the first value was omitted, on 

 account of the small number of observations. 



TABLE IV. 



Showing the percentage rate of growth of the babies of both series starting from 

 the second eight-day period of life. Control series being the breast-fed 

 babies and the other series being babies which were fed upon boiled cows' milk. 



The third method, giving the percentage deficit of the average 

 weights of the babies fed upon boiled cows' milk as compared with 

 the breast-fed babies, showed that at no period of life does the deficit 

 exceed 10 per cent., and that during the greater part of the period 

 under observation the deficit is much less.
