THE SECRETIONS : 



tained the following results from seven analyses. They are 

 calculated for 1000 parts : 



Extractive matter 



4-6 



3-2 



5-5 



2-5 



5-7

The urine in the 1st analysis was taken from a person suf- 

 fering from Bright' s disease without any complication. There 

 was a little fever present. It was of a greenish yellow colour, 

 very acid, and contained a little mucus. In the 2d analysis 

 the urine belonged to a patient in whom the disease had as- 

 sumed a chronic form ; it was greenish, clear, and acid. In 

 the 3d analysis the urine was taken from a person in a state of 

 convalescence, and who afterwards recovered. The 4th analysis 

 represents the urine of a man aged 35 years who was suffering 

 from polydipsia, with cedema of the feet, and ascites. The urine 

 was clear, alkaline, formed a diffuse, whitish sediment, and 

 effervesced briskly on the addition of acids. The man from 

 whom the urine of analysis 5 was obtained, had tubercles in 

 the lungs and Blight's disease in the first stage. There was 

 infiltration of the feet, and slight ascites ; the urine was 

 acid, pale, clear, and very abundant. The urine in the 6th 

 analysis was taken from a man who also had tubercles in the 

 lungs and Bright' s disease in the first stage : there was no 

 infiltration or dropsy : the urine was bloody and very acid. 



If we compare these analyses of morbid urine with that of 

 the healthy renal secretion, (the composition 1 of which is water 

 971*9, solid constituents $8'1, urea 12'1, uric acid 0-4, fixed 

 salts 6 '9, extractive matters 8*6,) we shall find that, with the 

 exception of analysis 1, the solid constituents are less than in 

 healthy urine, that the urea, with a single exception, only 

 amounts to l-3d or less of the solid constituents, whereas, 

 according to Becquerel, it constitutes nearly one half in healthy 



It must be remembered that this is Becquerel's analysis of normal urine. See p. 145.
