monia absorbed by the acid was made as usual with perchloride 

 of platinum, the double salt so obtained ignited and weighed, 

 the quantity of nitrogen being calculated from the weight of the 

 metallic platinum found. 



I. Night urine from the 29th to the 30th of August. 



(a) Fick : 5 cubic centims. of urine gave 0*3095 grm, plati- 

 .num = 0*043768 grm. nitrogen. Total quantity of nitrogen 

 6-915344 grms. 



(b) Wislicenus : 5 cubic centims. of urine gave platinum 

 0*2580 grm. =0*036485 grm. nitrogen. Total quantity of ni- 

 trogen 6*684052 grms. 



II. "Work urine. 



(a) Fick : 5 cubic centims. of urine gave platinum 0*2958 

 grm. = 0*418303 grm. nitrogen. Total quantity of nitrogen 

 3*312960 grms. 



(b) Wislicenus : 5 cubic centims. of urine gave platinum 

 0*4245 grm. = 0*060030 grm. nitrogen. Total quantity of 

 nitrogen 3*133566 grms. 



III. The after work urine. 



(a) Fick : 5 cubic centims. of urine gave platinum 0*4338 

 grm. = 0*06134545 grm. nitrogen. Total quantity of nitrogen 

 2*4293 grms. 



(b) Wislicenus : 5 cubic centims. of urine gave platinum 

 0*4272 grm. = 0*0604121 grm. nitrogen. Total quantity of 

 nitrogen 2*416484 grms. 



IV. 



Night urine from the 30th to the 31st of August. 



= 0*0933475 grm. nitrogen. Total quantity of nitrogen 



(a) Fick : 5 cubic centims. of urine gave platinum 0*6601 

 grm 

 in the 258 cubic centims. 4*816731 grms. 



(b) Wislicenus: 5 cubic centims. of urine gave platinum 

 0*7001 grm. = 0*099004 grm. nitrogen. Total quantity of ni- 

 trogen in the 270 cubic centims. of urine 5*346216 grms.
