Messrs. Parkes and Wollowicz on the [Recess, 



affect the excretion of phosphoric acid. The effect on the chlorine is 

 uncertain, as that ingredient has such a wide range of variation. It is, 

 however, interesting to note that the mean daily excretion of the whole 

 thirty days is almost precisely the same as the mean daily excretion of the 

 twenty-five days in the previous series (viz. 7 028 grammes as against 

 6*915 grammes), and this proves the equality of the diet. 



The acidity of the urine was increased during the wine-period, and this 

 continued afterwards. It may be observed that the mean free acidity of 

 the former experiments was almost precisely the same as in these experi- 

 ments during the water-period (viz. 1*974 as against 1955 gramme), and 

 was very nearly the same in the alcoholic as in the wine-period (viz. 2*342 

 as against 2*221). 



It seems fair to conclude that the free acidity was really increased, and 

 that the increase continued subsequently.

The nitrogen was determined twice, viz. on the 10th day (last day be- 

 fore wine), and on the 19th day (last day but one of wine). Unfortunately 

 there had been some constipation before the 10th day, and the stool was 

 unusually copious and less watery ; it represented, in fact, some accumula- 

 tion, and therefore the nitrogen ought to be credited in part to the previous 

 days.
