SULPHUROUS ACID AND SULPHITES. 997 



No. 8 has a fairly uniform quantity of total solids in the food 

 and a uniform excretion in the feces and urine, and no marked dis- 

 turbing influences are noticed as a result of the administration of 

 the preservative. 



In the case of No. 9 there is a marked increase in the excretion of 

 total solids in the feces in the after period, while there is a notable 

 increase in the amount eliminated in the urine in the preservative 

 period. The preservative period in this instance evidently has a 

 slight tendency .to inhibit the absorption of the total solids and to 

 increase the katabolic activities. 



With No. 10 there is' a considerable increase in the total solids 

 excreted in the feces both in the preservative period and in the after 

 period. The amount eliminated in the urine decreases in the pre- 

 servative period. There is a slight indication in this case of meta- 

 bolic derangement under influence of the preservative in respect of 

 total solids. 



In the case of No. 11 the quantities or total solids in the food and 

 the quantities excreted in the feces and urine show no marked vari- 

 ations in the three periods, but the same general tendency is indi- 

 cated as in the case of No. 10. 



In the case of No. 12 there is a slight increase in the quantity of 

 total solids in the feces in the preservative period and an increase in 

 the amount excreted in the urine. There is again a slight tendency 

 to inhibit assimilation and increase excretion. 



SUMMARIES. 



The summaries of Nos. 1 to 6 and Nos. 8 to 11, inclusive, are 

 interesting in showing the relations of the total solids in the food 

 and in the feces and urine, but do not throw any additional light 

 upon the subject of the effects produced by the administration of the 

 preservative upon the general metabolic activities as affecting the 

 total solids of the food. The variations between the periods as 

 shown in the summaries are very small, but indicate the tendency 

 noted for the majority of the individuals to inhibit assimilation and 

 increase elimination.
