The urine became alkaline each day after dinner, and 
twice after breakfast. On the third day, after breakfast, 
the urine sustained its acidity with a scarcely perceptible 
diminution ; though, as compared with the height to which 
it rose after the supposed alkaline tide had passed off, the 
depression was sufficiently marked, and still more marked 
if the hourly excretion of solids be taken into account, at 
the contrasted periods. 
In order to observe the effect of a longer continuance 
of an animal diet, the supper of mixed food on the previ- 
ous night was discontinued, and for three successive days 
animal food alone was taken. The following tables exhibit 
the results obtained.
