230 THE SECRETIONS: 



numbers which he gives do not, however, make out so large 

 a ratio. I calculate from the figures quoted in Meckel's 

 Archiv, 1 that Nysten's "urina sanguinis" contains 40 parts of 

 solid residue, of which 12 are urea, in 1000 of urine, whilst on the 

 other hand, in 1000 parts of his inflammatory urine there are 

 76 of solid residue, of which 22 are urea. The urine in the latter 

 case was evidently much more concentrated than in the former, 

 but the ratio of the urea to 100 parts of solid residue is the 

 same in both, and coincides with my own analysis and those 

 of Becquerel. It amounted to 30 parts of urea in 100 of solid 

 residue. 



Nephritis. 



In nephritis acuta the urine is, according to Schonlein, of 

 a dark red or claret colour, and contains hasmatin ; according 

 to Rayer the secretion is very scanty, especially when both 

 kidneys are diseased : it contains a certain quantity of blood 

 or albumen, and has an acid, a neutral, or even an alkaline re- 

 action ; it occasionally contains pus, as when an abscess com- 

 municates with the pelvis of the kidney, or when the nephritis 

 is accompanied by inflammation of the mucous membrane of 

 the urinary passages. 



Becquerel analysed the urine in five cases of acute nephritis, 

 and in none of them was blood present. The urine of a man 

 who had acute nephritis possessed the properties of inflam- 

 matory urine, but contained neither pus, mucus, nor albumen, 

 and deposited no sediment. In two cases accompanied with 

 hectic fever, the urine assumed the inflammatory type, but 

 contained no pus, and only, in one of the cases, a little albu- 

 men. In a woman who had, at the same time, disease of the 

 heart, chronic gastritis, and incipient cirrhosis of the liver, the 

 urine was highly inflammatory ; it was acid, formed a copious 

 uric-acid sediment, and contained some mucus and albumen. 

 In a woman aged 23 years, who had an anemic appearance, and 

 was suffering from slight polydipsia, and in whom the symp- 

 toms of acute nephritis showed themselves by violent pain in 

 the right kidney, by continual vomiting for above ten days, by 

 great anxiety and some fever, Becquerel observed that the
