Il existe des différences dans le choix de la nourriture: alors que tous les 

 animaux consomment des quantités égales d'hydrocarbures, les individus 

 adipeux montrent une prédilection pour les graines de tournesol, riches en 

 graisses, et cette prédilection est accentuée chez les diabétiques, en fonction 

 des troubles du métabolisme. 



9. Les Acomys diabétiques, rassasiés, piésentent des métabolismes de base plus 

 élevés que les normaux. Les plus hautes valeurs se trouvent chez les dia- 

 bétiques cétoniques. 



Chez les individus à jeûn. le métabolisme de base est en général plus bas 

 que chez les rassasiés. Seuls les diabétiques cétoniques présentent des valeurs 

 significativement plus élevées que les normaux.

1. Adult Acomys fed freely on a mixture of fats and carbon hydrates with carrots 

 added, but vvithout drinking water, show no increase in weight. With water 

 at their disposai, but vvithout carrots, their weight increases significantly. 



2. Foods rich in carbohydrates (corn, wheat, oat flakes), whether given together 

 or separately, together with water. induce a loss of eight in the adulte. If 

 fat-rich sunflower seeds are added. a gain in weight results. 



3. Growing Acomys put on weight faster, in the average, if they receive water 

 with the same fat-rich food mixture, than if they do not. 



The first diabetic disturbances of the metabolism can be detected after 

 one month of expérimentation, at the âge of 8 weeks. 



4. Studies of metabolism show four groups among the animais receiving a 

 fat-rich diet and water: 1. normals, 2. fat, 3. diabetic without cetone, 4. cetonic- 

 diabetic. 



5. Diabètes mellitus appears mor often in heavy-bodied animais than in lighter 

 ones. 



6. Measurements of sugar in the blood show that the metabolic disturbance is 

 réversible in cases of diabètes without cetone and irréversible in cases of 

 cetonic diabètes. 



7. The amount of proteins, as computed from measurements of residual nitrogen 

 and ammonia in urine, show an increase only in animais with cetonic diabètes. 



8. Food consumption is higher in individuals with non-cetonic diabètes than in 

 normal ones, and is even higher in those with cetonic diabètes.
