Hence in three cases of acute chorea the most remarkable increase was observed 
in the amount of sulphates in the urine. That this did not arise from the small quan- 
tity of urine passed is evident from the small amount of the total phosphates in the 
urine. Moreover the actual quantity passed, when it could be determined by mea- 
sure, was found occasionally to be above thirty ounces in twenty-four hours. It is 
worthy of notice that the amount of urea was also very greatly increased in these 
cases ; so much so, that on the addition of nitric acid to the urine without any eva- 
poration, nitrate of urea immediately crystallized out. 
A very small quantity of food was taken by these patients, whilst the muscular 
action was most severe ; and the contrast between the amount of sulphates when they 
were recovering and taking full diet, and the amount when they took little food, but 
were in a state of violent muscular action, is very remarkable. 
The general conclusion is, that in acute chorea the amount of sulphates in the 
urine is increased, whilst the phosphates are in some cases as remarkably diminished.
