proof may obtain the information they seek in the Lectures of 

 Professor Liebig on Chemistry. The annexed table shows the 

 proportion of the two classes of elementary materials in the 

 following articles of food : 



A reference to this table will show why a horse fed on potatoes 

 gets fat, but can do little work, why barley is better than potatoes 

 for working purposes, and why oats are still better than barley, 

 because the proportion of muscle-making matter in them is 

 greater than in barley, and nearly double what it is in potatoes. 

 So in regard to the dog, it will be seen that the building-up 

 power of flesh is, on an average, nearly three times as great as that 

 of wheat or oatmeal, the former exceeding the latter in a slight 

 proportion. Cow's milk contains about the same proportion as 

 would be found in an equal mixture of flesh and meal, and upon 

 it dogs will thrive ; but they fall off when first put upon other 

 food. The peculiar characters of flesh are exemplified in a 

 remarkable manner in the flesh of the hare, which contains only
