URINE. 239 



could be detected. I noticed the following case of albuminuria 

 in Schonlein's wards. A man suffering from pneumonia passed 

 very turbid urine till the period of incipient resolution ; it had 

 a very acid reaction, and after several hours' rest deposited no 

 sediment. The turbidity arose from urate of ammonia in sus- 

 pension, it disappeared on the application of heat, and again 

 became apparent as the urine cooled. The urine presented 

 this jumentous appearance for six days ; on the seventh there 

 was a slight flocculent amorphous deposit of urate of ammonia. 

 On gently warming the urine the sediment perfectly dissolved, 

 but at a boiling heat it became turbid from the separation of a 

 considerable amount of albumen. On the following day the 

 urine was very turbid in consequence of the presence of urate 

 of ammonia, the amount of albumen remaining much the same. 

 From that date the urine became clear, but remained albu- 

 minous till convalescence was established, the albumen gradually 

 disappearing as the health improved. During the whole of this 

 period the patient complained of no pain in the region of the 

 kidney, even on strong pressure ; neither was there any depo- 

 sition of mucus. 



A man treated antiphlogistically for a severe attack of arti- 

 cular rheumatism passed, for a considerable time, urine of a dark 

 colour and very acid reaction, which, however, threw down no 

 sediment. During the period of convalescence, when the 

 swelling and pain had diminished, the urine became less acid, 

 without any appearance of a sediment; the sweat, however, was 

 still extremely acid, and one morning the urine contained a 

 very considerable amount of albumen. 



This abnormal constituent occurred in the whole of the 

 urine excreted that day; on the morrow it was nearly gone, 

 and on the third day had quite disappeared. No renal irri- 

 tation could be detected, neither was any sediment ob- 

 served. 



The urine of a young man with all the signs of general 

 dropsy contained a considerable amount of albumen, and de- 

 posited a light mucous sediment containing a considerable 

 number of colourless blood-corpuscles (recognizable by their 

 discoid form), numerous exudation- globules, mucus-corpuscles, 

 and a few of the tubes described in page 235. The urine had 

 the pale, green, opalescent appearance indicative of the presence
