ANALYSIS OF BIABETIC URINE.

man in health, and the patient was cured. Immediately 

 on this however he indulged in excesses of various kinds, Excesses 

 when the diabetes returned, compUcated with other disor- ^"^^"f^!)^ °" * 

 ders, under which he soon sunk. 



If now we take a review of all the inductions that may General con-, 

 fee made from the experiments just related in the second ^^^^sious. 

 and third part of our memoir, we may affirm 



1. That the diabetic urine we examined was composed State of the 

 almost wholly of a substance but little saccharine : and "'^"^^• 

 that nevertheless it possesses all the properties that charac- 

 terize sugar ; for it is converted into alcohol and carbonic 



acid by fermentation, afFoi'ds a great deal of oxalic acid 

 and no mucous acid when treated with nitric acid, is very 

 iittle soluble in alcohol at 36^, and produces v/hen calcined 

 but little oil, aad a great deal of water and carbonic acid. 

 And thus it is demonstrated, that there are different varie- 

 ties of sugar. 



2. That raann^ is not a species of sugar: that it contains Manna not *n- 

 but a small quantity, which may be destroyed by fermen- gas^- 



tation : and that, on the contrary, it contains a great deal 

 of a peculiar principle, the taste of which is very sweet, 

 and the chief characteristics of which are not to ferment 

 v/ith yeast, to yield a great deal of mucous acid with nitric 

 acid, and to be more soluble in hot than cold water, but 

 particularly in alcohol, so that the solution on cooling be- 

 comes a crystalline m-ass. 



3. That if nothing but animalized food be given to diabetic An ar.fmal <1ie.j 

 patients, their urine chan^jes its nature pretty quickly: that '*"^^"'®j 



at first we find in it an albuminous matter; that this albu- 

 minous matter the gi\antity of which continues increasing 

 for some days, appears to be an unequivocal sign of a 

 cure; that afterward the albumen gradually disappears: 

 that the kidneys then begin \p secrete uree, lithic acid, 

 and no doubt acetous acid also : and that the urine soon 

 becomes similar to that of a person in health: but that b^j p„,^t 1^ 

 nevertheless, to prevent a relapse, the patient ought still continued long
