URINE. 265 



Traces of iron were detected both in the sweat and urine 

 during the period of treatment.] 



Donne states that normal urine always contains a certain 

 quantity of iron which disappears during chlorosis, and only 

 reappears after the use of ferruginous preparations. This state- 

 ment is contradicted by Becquerel, who has never been able to 

 discover iron in the incinerated residue of normal urine, 

 although ferrocyanide of potassium would evolve a blueish shade, 

 an effect which this test sometimes has on chlorotic urine. 



[L'Heretier 1 gives the mean of eight analyses of the urine 

 in uncomplicated chlorosis : 



In 24 hours.

I am indebted to the kindness of Dr. Golding Bird for the 

 following cases : 



1. A girl aged 18 years, of anaemic appearance, and who had 

 suffered from anasarca for six months, passed 30 ounces of acid 

 urine of specific gravity 1024, in twenty-four hours. 



The water amounted to . . 12690 grains. 



The solids .... 750 



Urea . . . .162 



Uric acid ... 9 



She then commenced taking ferri sulph. gr. iij, ter die. In 

 the course of a week the urine was again examined ; it amounted 

 to 20 ounces, had a specific gravity of 1029, and deposited urate 

 of ammonia. 



The water amounted to . . 8392 grains. 



The solids . . . .608 



Urea . . . . . 137 



Uric acid . . . 20
