Fokker's Method. A method of estimating uric acid in 

 the urine. 200 c.c. of urine are made strongly alka- 

 line by sodium carbonate, and after an hour 20 c.c. of a 

 concentrated solution of ammonium chlorid are added . 

 The mixture is allowed to stand at a low temperature 

 for 48 hours, when the precipitate that forms is collected 

 on a weighed filter and washed. The filter is washed 

 with dilute HC1 (1 in 10), and the filtrate collected; 

 this operation is repeated till all the acid urate on the 

 filter is dissolved. The filtrates are mixed, allowed to 

 stand for 6 hours, and the uric acid which then 

 separates is collected on the same filter, washed twice 

 with water, then with alcohol, till all acid reaction dis- 

 appears, dried at no C, and weighed. To the 

 weight obtained add 0.03 gram, and subtract the 

 weight of the filter ; the remainder is the weight of uric 

 acid in 200 c.c. of urine. 



Fol's Fixing-fluid. A modification of Fleming's solu-
