 was present. 



The urine of the first two analyses was of a pale-yellow co- 

 lour, and slightly acid ; in the third case it was as clear as water, 

 and produced no change on test paper. 



The two following analyses were made with the urine of a 

 girl aged 20 years, who was being treated for diabetes mellitus 

 in Prof. WolfFs clinical wards. 



The first analysis was made eight weeks before the second ; 

 I made an analysis of the blood at the same time. (See Analysis 

 42, Vol. I, page 327.) 



The second analysis was made two days before death ; it re- 

 vealed the fact that the diabetes sapidus had changed into dia- 

 betes insipidus ; moreover, at this period, the urine contained a 

 considerable quantity of albumen.

Analysis 134 was made with the urine of a man aged 52 years, 

 who was being treated in Schonlein's clinical wards for diabetes. 

 The urine was not passed in very large quantity, but it con- 

 tained a remarkably large proportion of sugar. The composi- 

 tion of the blood, which also contained sugar, is given in 

 Analysis 41, Vol. I, page 327.
