The importance of the mother working during her pregnancy 

 has often been brought before you and need not be dilated upon. 

 In Table VII it will be seen that of 166 women who had to

 535 women who did not have to work the mortality rate was 

 131 per 1,000 born.

 Table VIII. Of 225 American-born mothers the mortality was 

 210 per 1,000 born, as compared with 533 foreign mothers with

 of the fact that breast feeding is more common among them 

 and they nurse for a longer time.

The second item, which I wish to present to you in brief, is 

 the cause of infant mortality during the summer time. As is 

 well known, death takes place under the guise of a so-called 

 summer diarrhoea, and what the cause of this summer diarrhoea 

 is, is by no means clear. A pathological change in the sense 

 of inflammation, as is understood by the terms "enteritis" and
