While the critic might justly say that these dietaries lack variety and would not appeal to a fastidious taste, there is force in the illustration which they afford of a simple diet being quite adequate to meet the wants of the body. Further, it should be emphasized that there is no special virtue in any of these dietaries, aside from their simplicity and low content of nitrogen. They represent individual taste and selection. Any other form of diet would answer as well, provided there was not too large an intake of proteid, and provided further the fuel value of the day’s ration was sufficient to meet the requirements for heat and work. Again, it might be said that with this latter subject the daily consumption of proteid food was considerably larger than with the first subject. This is indeed true, but it must be remembered that the second subject had a body-weight of 70 kilos during the last seven months, while the first subject weighed only 57 kilos. Obviously, with this marked difference in the weight of living tissue there must be a corresponding difference in the extent of proteid katabolism, and consequently a difference in the demand for proteid food.
