milk, 78 had never received the breast and 41 had received it for 

 periods which in no case exceeded eight days, and in many cases 

 was considerably less. Among the breast-fed series 130 infants 

 out of the 300 were taken, who had received only the breast up 

 to the 200th day of life or longer. 



A comparison of these two subsidiary series 1 on the same lines 

 as before showed a rather greater divergence of the curves during

 Diagram n, which gives the weights up to the 200th day. 



The rate of growth was also studied in a similar manner to 

 that already explained in the two main series, and showed that 

 although the percentage rate of growth was slightly less in the 

 artificially-fed infants, here again the tendency was shown for
