DR. BENCE JONES ON THE VARIATIONS 
From the comparison of these numbers, as seen in Plate XVIIL, with those ob- 
tained when a mixed diet was taken, as in Plate XVI., it is apparent, — 
1st. That the diminution of the acidity after food is more marked, and continues 
longer when animal food only is taken, than it does when mixed diet is eaten. 
2nd. That the acidity before food rises rather higher with a mixed diet than it 
does with animal food only. 
There is the same exception observable on the second day of animal food as was seen 
the third day when mixed diet was taken. At ten minutes after seven the urine had 
an acidity for every 1000 grains marked by 17‘52 measures. At fifty minutes after 
eight (just before breakfast) the acidity was diminished to 10'71 measures. There 
was but little difference in the specific gravity of the two quantities. 
For three days consecutively vegetable food only was taken, twice each day.
