ANALYSIS OF DIABETIC URINE. OQJ 



2. The very peculiar nature of the saccharine substance 

 we found in this urine : and 



3. The various changes this urine underwent before it 

 was brought back to its primitive composition. 



Part I. Observations made on the patient, whose urine Observations 



, on the disease. 



we examined. 



From these observations it follows: 1. That the saccharine May continue 

 1- , , ,• , , 1 several years, 



diaoetes may conlmue several years, and even as long as 



the digestive powers can maintain themselves, and supply 



the excessive waste occasioned by the urine. 



2, That this disease is not incurable at any period, not Curablo at ary 

 even when the impaired digestion appears unable to supply ^^'^^° ' 

 the materials of the secretion that exhaust the animal eco- 

 nomy. 



•3. That the seat of this affection appears to be in the Its seat the kid^ 

 kidneys, not in the intestinal canal. "^y** 



In fact neither the appetite nor thirst of a diabetic patient 

 is any way depraved: they both, as well as the digestive 

 pjowers, appear merely to be proportional to the want of re- 

 paration ; in the next place the aliment undergoes the same 

 preparation in the stomach of a diabetic patient as in that 

 of a man in health ; and what completely proves, that the 

 digestive faculty is not altered, but simply increased, in 

 diabetic patients, is the quantity of food they take, the 

 quickness with which it is digested, the large proportion of 

 it conveyed into the circulation, and the small quantity of 

 faeces to which it is reduced ; and lastly, from the digestion 

 of the food till the secretion of the urine, we find no fluid 

 at all saccharine, or that has undergone any change in its 

 composition. 



4. That the cause of the saccharine diabetes appears to its cause their 



be an increased and depraved action of the kidneys; that increased and 



„ , . . , J . vitiated action, 



the saccharme matter or the urme is produced m conse- 

 quence of this action; and that to it all the symptoms of 

 the disease are to be traced. 



5. That the excessive loss, which takes place in this Supeificial ab- 

 disease, seems under some circumstances to occasion a sorption m- 

 pretty considerable absorption at the surface of the body. 



6. That the new proportions established by the saccharine secretions af-
