Uric Acid. (See Illus. Diet.) Hopkins-Folin 

 Method of quantitative determination of. The fol- 

 lowing reagents are necessary: ( I ) A solution of 1 

 liter volume containing 500 gnu of ammonium sulfate; 

 5 gm. of uranium acetate ; 60 c.c. of lO<£ acetic acid ; 

 and distilled water to bring the bulk up to I liter. 

 (2) A one-twentieth normal solution of potassium per- 

 manganate. Place 300 c.c. of urine in a beaker, add 

 75 c.c. of the ammonium sulfate reagent, and mix thor- 

 oughly. After the precipitate has settled sufficiently 

 filter through a double-folded filter. "Ahen 250 c.c. 

 of the filtrate has passed through, this volume is divided 

 into two portions of 125 c.c. each, to serve as a dupli- 

 cate. To each portion add 5 c.c. of concentrated water 

 of ammonia, mix thoroughly, and allow to stand over- 

 night. The precipitated ammonium urate is then 

 transferred to a filter and washed with a \o% solution 

 of ammonium sulfate. Then wash the precipitate 

 with about IOO c.c. of water into the same beaker, 

 add 15 c.c. of concentrated sulfuric acid, and immedi- 

 ately titrate with N - 20 solution of potassium perman- 

 ganate until the first permanent tinge of pink color 

 appears. One c.c. of potassium permanganate solu- 

 tion equals 3.75 mgm. of uric acid. From this calcu- 

 late the amount in 24 hours.
