290 THE SECRETIONS: 



[In my paper 1 on the specific gravity of the urine in health 

 and disease (founded on 200 observations), I have shown that 

 Christison's formula, A x 2' 33, gives more correct results than 

 the above table. A indicates the excess of the specific gravity 

 over 1000. Thus, supposing it is desired to ascertain the 

 amount of solid matter in 1000 parts of urine whose specific 

 gravity is 1035, A is here represented by 35, and 35 x 2-33=81 -55, 

 the required number.] 



According to Schonlein there is no sugar in the urine in the 

 first stages of the disease, but albumen ; and as the albumen 

 subsequently disappears the formation of sugar in the urine 

 commences. 



The quantity of urine increases in an extraordinary degree. 

 P. Frank mentions a case in which fifty-two pounds were dis- 

 charged during twenty-four hours. According to Bouchardat,
