URINE. 309 



passed, which speedily deposits a considerable sediment of a 

 brick-dust or rose-red colour ; in some few cases a clear, trans- 

 parent urine, like that which is passed in spasm, is discharged 

 in tolerable abundance. 



I have analysed the urine of a man who was suffering both 

 from hydrothorax and cavities in the lungs. It was deeply 

 coloured, had a strong acid reaction, contained no albumen, and 

 formed a slight sediment of urate of ammonia. 



Its specific gravity was 1025. Its composition was as follows:

In ascites inflammatorius the urine is secreted in diminished 

 quantity, is of a dark red or brownish colour, and not unfre- 

 quently contains blood in a state of solution, or blood-corpuscles; 

 the latter may be recognized by the microscope, and if the urine 

 is allowed to stand, they form a red sediment j frequently, how- 

 ever, no hsematoglobulin but merely albumen is present. On 

 the approach of recovery, there is, according to Schonlein, a 

 copious discharge of urine, accompanied by a purulent, and 

 subsequently a mucous sediment. 



At the commencement of chronic ascites the urine is not 

 much diminished in quantity ; it assumes a pale or opalescent 

 shining green colour, and contains a large quantity of albumen 

 and mucus. 



Persons suffering from periodic ascites pass a small quantity 

 of red, turbid urine, which sometimes deposits very copious se- 

 diments of uric acid and urate of ammonia. Towards conva- 

 lescence, the discharge of urine becomes very abundant, and 

 it continues to throw down copious lateritious sediments. The 

 occurrence of a clear, slightly coloured, spastic urine, without 

 these critical sediments, must be regarded as an unfavorable 

 symptom, since it indicates renal " colliquation." (Schonlein.) 



In those varieties of ascites that arise from affections of the liver, 

 spleen, stomach, and generative organs, the amount of urine is
