pounded in a mortar with ether, and left in a bottle with ether for 
several hours. The ether was decanted off, and the oats extracted 
in the same way six times. The ether extract weighed 3*3 grms. 
Two rabbits were starved for two days. To one the oats, de- 
prived of fat as above described were given, to the other 110 
grms. of oats from the same sample, not so extracted. Both 
rabbits took the food well — the whole quantity being consumed in 
about twelve hours. Twelve hours after, the rabbits were killed, 
and a piece of intestine four inches below the opening of the 
pancreatic duct was taken from each, along with a piece near the 
ileo-c8Bcal valve. In the first rabbit no fat could be detected in any 
of the cells, but in the second, fat in small and scattered globules 
was found in the cells at the tops of many of the villi. 
Experiment II . — Two rabbits which had been in the same cage, 
and were in good condition, were taken. A was fed on oats ; B 
received rice, which, however, it did not take well. On the second 
day of the experiment it was fed on turnips, which it took greedily. 
They were kept on these diets for ten days, ^nd both maintained 
their weight.

Oats contain about 5 per cent, of fat — 5’6 of the dry substance. 
Turnips contain about 0*2 per cent, of fat — 1*5 of the dry 
substance. In oats, fats are to carbohydrates as 1 to 11. 
In turnips, fats are to carbohydrates as 1 to 47. 
On the 26th the animals were killed, and the intestine examined 
as described above. 
In A there was a very small amount of fat in very small globules, 
and entirely at the tips of the villi. In B no fat whatever could 
be detected. 
But it is only by experiments upon animals in which the ali- 
mentary canal can be readily and completely emptied that satisfac- 
tory results on this subject can be obtained. For this purpose rats
