determine the quantitative relation between cystin and other con- 
stituents of the urine, in this disease. - The most noteworthy fact 
observed was that the per cent of cystin stood to that of the sul- 
phuric acid as 1:3°89, and that the two varied together. The 
quantity of uric acid was diminished, but that of the urea was not 
sensibly affected. The patient excreted from 0°4234 to 0°595 
gram cystin per day.—Liebig’s Ann., clxxxvil, 101 suey 187 *
