FOOD OF PUPPIES. 267 
The comparative value of the various articles of diet enumerated 
above, according to the authority of Liebig, is as follows :—

From this high authority it appears that barley-meal is superior 
both to wheat-flour and oatmeal in fat-making materials, but it is 
greatly inferior in muscle-making power, and hence, in dogs where 
fat is not required, it is of inferior value. Science and practical 
experiment here go hand in hand, as they always do when the 
former is based upon true premises. In cow’s milk, which is the 
natural food of the young of the Mammalia, the proportion is 30 
to 10, and this seems to be about what is required in mixing the 
animal and vegetable food. Now, by adding equal weights of 
wheat-meal and lean horseflesh, we obtain exactly the same pro- 
portions within the merest trifle; thus—

—being equal to 10 of muscle-making to 303 of fat-making matter ; 
and this is practically the proportion of animal food to meal which 
best suits the dog’s stomach and general system. The reader 
is not to suppose that a dog is to be fed on equal parts of cooked 
meat and puddings, but of vaw meat and dry meal, which when 
both are boiled would, by the loss of juice in the flesh and the
