SULPHUROUS ACID AND SULPHITES. 



961 



In the case of Nos. 8 to 11, inclusive, there is an increase in the 

 amount of fat ingested during the preservative period and also an 

 increase in the amount in the feces. When the quantity of fat falls, 

 as it does in the after period, to the same magnitude as that in the 

 fore period, we find there is still an increase of fat in the feces, indi- 

 cating an inhibitory effect. This is an indication, though not of a 

 very marked character, that free sulphurous acid, even though 

 administered in smaller doses, tends more strongly than sulphurous 

 acid in the form of sulphites to interfere with the digestion of fat. 

 This interference, however, is too slight to warrant serious consider- 

 ation, especially in connection with the variations in condition 

 between the two groups which have already been noted.
