mind. Protein, in the absence of carbohydrates, may be 
consumed in maintaining vital heat and energy or even 
in producing fat in the body, but carbohydrates never can 
take the place of protein. This fact should be firmly 
fixed in mind, as on it depends very often the success of 
feeding. An animal fed carbohydrates alone would starve
