 I made an analysis of healthy urine of specific gravity 1*0185 



about the year 1824, and obtained from 1000 grains of it the 



following substances : 



Phosphate of lime, . 0-209 

 Phosphoric acid, . 1*131

* MM. Cap and Henry have shown by experiments which appear conclusive, 

 that the urea in urine is in the state of lactate, being combined with lactic acid. 

 See Jour, de Pharm. xxv. 133. 

 Lactate of urea is composed of, 



1 atom lactic acid, 8-875 

 1 atom urea, . 7 "5
