LUNG WEIGHTS IN RELATION TO EMPTY WEIGHT AND WEIGHT OF PROTEIN 
The figures for the weight of lungs in relation to empty weight are 
plotted in figure 7, and those in relation to weight of protein in figure 8. 
The empty weights and the weights of protein are used as the abscissas 
and the weights of the organs as ordinates. The weights of protein were 
approximately one-tenth of the empty weight, and to make the curves 
more comparable the protein figures were multiplied by 10. As pigs 
increase in size or in amount of protein, the lungs increase irrespective of 
the nature of the ration.
