DR. BENCE JONES ON THE VARIATIONS OF THE SULPHATES. 
the state of chorea was still closer, inasmuch as occasionally a very great excess of 
urea was found in these cases also. 
Table III. In acute inflammatory diseases of the nervous structures, during the 
most febrile symptoms, an increase was observed in the amount of sulphates in the 
urine, and the total amount of earthy and alkaline phosphates in tflese diseases ap- 
peared to be increased in the same proportion as the sulphates were increased. 
Table IV. In some slight and chronic diseases of the nervous structures, no increase 
in the amount of sulphates in the urine was observed, excepting when sulphate of 
magnesia had been taken as a medicine. 
Table V. In acute diseases, in which neither the nervous nor the muscular struc- 
tures were chiefly affected, no increase in the sulphates or phosphates was observed, 
except after sulphate of magnesia. 
Table VI. In chronic diseases, in which neither the nervous nor the muscular 
structures were chiefly affected, no decided increase in the sulphates or phosphates 
in the urine was observed, except after sulphate of magnesia. One case of exostosis 
may be regarded as a doubtful exception to this statement. 
The general conclusions are — 
1. That in acute chorea, in which the muscles are in excessive action, the sulphates 
and urea in the urine are greatly increased. 
2. That in delirium tremens the same state of urine is frequently met with; that in 
these diseases the phosphates are not at all increased. 
3. That in acute inflammation of the nervous structures, sulphates and phosphates 
are both increased in the urine. 
4. That in chronic diseases of the brain, and that in other acute inflammations and 
diseases and in other chronic diseases, no increase in the total amount of sulphates is 
observed, excepting when sulphate of magnesia is taken as a medicine. 
The result of this investigation is that — 
Muscular action increases the sulphates in the urine without increasing the phos- 
phates ; whilst 
Inflammation of the brain increases both the sulphates and phosphates in the urine.
