98 Memoir on the Saccharine Diabetes. 
2d, The very peculiar nature of the saccharine substance 
we found in that urine. : 
$d, The different transformations which it underwent 
before being brought back to its natural appearance and 
consistency. 
Part First. 
Medical Observations upon the Case in which we analysed 
the Diabetic Urine. 
It resulted from these observations : 
ist, That the saccharine diabetes may last several years, 
and even as long as the digestive faculties continue, and are 
able to administer to the excessive losses which take place 
through the urine. 
2d, That this disease is not incurable in any of its stages, 
not even when an altered digestion seems no longer to fur- 
nish matters of secretion and the animal ceconomy is ex- 
hee ; 
, That the seat of this affection seems.to be in'the kid- 
Be nor not in the intestinal canal. 
_ In fact, the appetite and thirst of diabetic patients are 
not perverted; they appear merely to be in proportion 
to the want of organical repair, as well as the digestive 
faculties; in the second place, the alimentary substances 
undergo the same operation in the stomach of a diabetic pa- 
tient as in that of a healthy person; and what proves that 
the digestion is not altered, but merely increased, in diabetes 
is, the quantity of food taken, the rapidity with which it is 
digested, the great proportion of matter which is absorbed 
from that food, and the small quantity of faeces to which it 
is reduced: in short, we find no saccharine liquid, or any 
liquid which has undergone any alteration in its composi- 
tion, all the way from the organs of digestion to those of 
the urinary secretion. 
4th, That the cause of saccharine diahewse appears to be 
a heightened and perverted action of the kidneys. 
That in consequence of this action the saccharine matter 
of urine is produced, and to this cause we may ascribe all 
the symptoms of this malady.
