(15)—This is one of the evils indirectly caused by artificial feeding. The 
direct evil caused by it, in increasing infant mortality, is certainly worse. 
Research on this subject dates back to Villerme, and has been lately made 
wider and more accurate by Silbergleit, Sterneberg, Methorst, and Huber. 
In a work, published in 1905, Silbergleit showed that for Berlin the 
mortality of children naturally fed during the first year of life was equal to 
5‘7%, and rose to 23*4% among those fed on cow milk. 
At Nimega Sterneberg found a mortality of 5'3% for children naturally 
fed and 35*5% for the others. At the Hague the mortality for those born 
in 1908 was 3'44% in the case of children naturally fed for at least eight 
weeks, and n‘86% for those artificially fed. In France amongst children 
sent out to be nursed in 1907 the mortality for the first year of life for those 
naturally fed was 33%, for the others it was 50%; but probably, as Huber 
says, the difference is really greater than is indicated by these figures, owing 
to the fact that some of the children considered as naturally fed some­ 
times have to receive additional nourishment. 
It is, however, impossible to decide how far the differences shown are 
due to differences in feeding or how far they may be due to differences in the
