INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



inappreciable and a slightly increased loss during the after period. 

 The weights, however, in all four instances when brought together in 

 a general expression show but little change during the progress of the 

 experiment. 



In the case of Series IV, No. 8, there is a marked loss of weight 

 during the preservative period and a somewhat greater loss during 

 the after period. (See fig. 5.) 



In the case of No. 9 the same observation may be made, though the 

 losses are not so great as in the case above mentioned. No. 10 also 

 shows a regularly graded loss, it being almost the same in the after 

 period as in the preservative period. 



FIG. 5. Daily and average body weights for Series IV. 



Combining the three expressions into one we find a progressive loss 

 of weight, being almost exactly the same in the after period as in the 

 preservative period. 



In the case of Series V (fig. 6) the preservative period extended over 

 a space of fifty days. The vertical lines, therefore, in this chart repre- 

 sent two days instead of one through all the periods of the series. 



In the case of No. 1, Series V, there is a slight loss of weight shown 

 during the preservative period, which is almost exactly regained 

 during the after period. 



In the case of No. 3 contrary data are shown. There is a slight 

 increase of weight during the preservative period, which disappears 

 entirely during the after period. 



In the case of No. 5 there is a very marked loss of weight during 

 the preservative period and an equally marked additional loss during 

 the after period.
