INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



slight tendency is shown here to an increase in weight, while the quan- 

 tity of food consumed remains practically constant. The dry food 

 consumed, expressed as percentage of body weight, is 1.02 during the 

 fore period, during the preservative period 1.03, and during the after 

 period 1.02, showing a remarkable constancy in this particular. As 

 is seen under variations in body weight, no marked influence is shown 

 in the case of sulphurous acid, while for those receiving sodium sul- 

 phite there is a decrease in weight both in the preservative and after 

 periods.
