URINE. 223 



Martin Solon 1 states, that in twenty-four cases of pleuropneu- 

 monia, he found albumen in twenty-two; it was especially 

 observed at the period of the crisis. 



Empyema. 



It was known to the ancient physicians that effusions of pus 

 into the thoracic cavity are, under certain circumstances and 

 peculiar treatment, carried away by the kidneys. 



Schonlein has observed several such instances, and I have 

 had several opportunities, in the clinical wards of our hospital, of 

 seeing cases of pleuritis with empyema, in which, after a proper 

 course of treatment, turbid urine was discharged for some days. 

 This urine contained albumen, and deposited a sediment, which, 

 under the microscope and in its general physical relations 

 resembled pus, or (in one case,) mucus mixed with pus. 



The urine, which after some time became clear above the 

 sediment, was of a dark colour, only slightly acid, and soon 

 became alkaline. The symptoms of empyema gradually dis- 

 appeared, in proportion as the urine continued to form purulent 

 sediments. 



Emphysema. 



Becquerel has examined the urine in eight cases of pulmo- 

 nary emphysema. When the emphysema produces violent 

 dyspnoea, frequent cough and much general disturbance, the 

 urine assumes the inflammatory type. Becquerel made one 

 analysis of urine of this nature ; it was of a dark brown colour, 

 had an acid reaction, but deposited no sediment. Its specific 

 gravity was 1016-8. It consisted of 



In 100 parts of solid residue.
