INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



greater than the amount of preservative sulphur ingested, while in 

 the case of sulphurous acid the increase corresponds almost exactly 

 to the amount of preservative sulphur ingested. 



The increase in the feces, considering the same tendency shown in 

 the nitrogen and phosphoric-acid balances, can hardly be attributed 

 to an elimination of preservative sulphur through this channel, but 

 rather, as is before mentioned, to a decrease in assimilation and 

 absorption from the ingested food. This fact, together with the 

 probable increase in katabolic activities shown as regards the sulphur, 

 indicates that the administration of the preservative produced decid- 

 edly unfavorable effects. 



These tendencies are more marked in the case of sodium sulphite, 

 though the variations in the conditions of the experiment must be 

 considered in making this statement.
