Plate XX. admits of a comparison with those previously given. 
The nine drachms 
of dilute sulphuric 
acid do not appear to heighten the acidity before food, though the 
diminution of the acidity after food is certainly less marked than when no acid was 
taken, and mixed diet was eaten. In the third part of this paper, on the Variations 
of the Sulphates in Health, I shall show that a similar mode of inquiry gave no posi- 
tive results as to their increase in the urine after sulphuric acid was taken ; but by 
examining all the urine passed in twenty-four hours, positive results were obtained. 
A similar course was therefore adopted regarding the acidity of the urine.
