Analysis 1 was made on Oct. 22d, before the administration 

 of any remedies. The urine was faintly acid. The soluble 

 salts consisted for the most part of chloride of sodium. Analysis 2 

 was made on the 3d of November with the mixed urine of the 

 preceding twenty-four hours. It had a strong ammoniacal 

 odour, but was perfectly neutral. The patient had taken sul- 

 phuric acid, iron, and other tonics, in the interval, without any 

 obvious improvement, and traces of iron were found with the 

 earthy phosphates. Analysis 3 was made with the morning 

 urine passed on the 25th of November. The same treatment 

 had been pursued with very decided benefit. The urine was 

 clear, slightly yellow, and devoid of the unpleasant odour it 

 previously evolved. Its reaction was faintly acid, and it con- 

 tained traces of iron. 



The green colouring matter is probably a compound of uric 

 acid and biliphsein. A compound of this nature has been ob- 

 served and described by Heller. 1 ] 



Chlorosis. 



The urine of chlorotic persons is usually pale, of low specific 

 gravity, and of a mildly acid reaction : in these respects it re- 

 sembles the urine of persons who have lost a considerable quan- 

 tity of blood, or the form of urine termed nervous, which we 

 sometimes observe in hysterical attacks. 



Becquerel applies the term anaemic to this form of urine, and, 

 as in the majority of cases in which it occurs, there is either 

 an absolute deficiency of blood or a scarcity of the truly vital por- 

 tion the blood-corpuscles, no objection can be raised to such 

 a designation. The urine in chlorosis has, however, other dis-
