Detailed statistics of incomi tmdoutgo. The quantities of nutrients in the basal ration and 

 the quantities in the supplemental ration in the different experiments of this series are shown in 

 Table XLYIII. No attempt was made in this experiment to obtain a separation of the feces 

 between experiments 22 and 23, since it was believed the amount of such excretion during the 

 alcohol experiment would not differ materially from the amount in the following experiment in 

 which alcohol was not used but in which the diet was otherwise the same, with the exception of 

 the small amount of horse-radish. It is our experience that too frequent separation of the feces 

 renders the line of demarcation less accurate. The separation of the feces was. however, made 

 between experiments 23 and 24. The data of amount and composition of the feces of the two 

 experiments are given in Table XL1X.
