DE. PAVY ON SUGAR POEMATION IN THE LIYEE. 
The effect of giving an admixture of sugar with animal food is similar to that pro- 
duced by a vegetable diet. The sugar employed in my experiments was the brown or 
moist sugar that is used for domestic purposes. Various de'rices had to be resorted to 
to get the animal to take it. The plan I found to succeed the best was to introduce it 
into short lengths of the small intestine forming part of the bundle of tripe. I will give 
the leading particulars belonging to each of the four dogs that formed the subjects of 
experiment in this way. 
No. 17. A nearly full-grown mongrel dog, kept for eight days on a diet consisting of 
sugar and a bundle of tripe j^er diem. At first one-third of a pound of sugar was admi- 
nistered daily, but after three or four days the animal showed a disinclination for food, 
vomited, and had bilious diarrhoea. The quantity of sugar was reduced to a quarter of 
a pound daily. The dog now devoured voraciously all that was given to it. The uiine 
collected from the bladder after death gave a strong reaction of sugar (grape-sugar). 
No. 18. A youngish dog, fed for nine days on a bundle of tripe and a quarter of a 
pound of sugar daily. It consumed its food well at first, but during the last few days a 
great amount of coaxing was required to get it to take its full allowance. There was 
scarcely any urine to be procured from the bladder after death ; what there was gave no 
saccharine reaction. 
No. 19. A middle-aged dog, kept for eight days on a bundle of tripe and a quai-ter 
of a pound of sugar daily. The urine at death gave a slight but decided reaction of 
sugar. 
No. 20. A dog not quite full-grown. Fed for five days on the same diet as the pre- 
ceding dog. The urine collected after death gave a strong reaction of sugar.
