Dr. Beaumont found that the envelope of the seeds 

 of the apple and the skins of potatoes were scarcely 

 acted upon by the gastric juice, and that they were 

 consequently indigestible. As a whole, it would 

 seem that animal aliments are digested easier than 

 vegetable ones ; but his experiments show conclu- 

 sively, that, whatever the kind of food, the ultimate 

 principle of nutrition, or the chyle, is the same in all 

 eases. 



Digestion is much facilitated by the particles of 

 food being made fine when taken into the stomach, 

 and the quantity of nutritive matter furnished is 

 greater. Individuals, therefore, in whom -the digest- 

 ive powers are weakened, find a benefit in thorough- 

 ly masticating or chewing their food. This princi- 

 ple is of great importance in the feeding or fattening 

 of animals, and shows the necessity of grinding or 

 cooking the materials given them if we would have 

 them derive the full benefit of the nutritive matter 

 contained. 



The experiments of Dr. Beaumont farther prove, 

 that when food of great nutritive powers is taken
