Injury, recovery, and death, in relation to conductivity and permeability . the composition of the mixtures; thus at the point M the mixture contains of solution 1 to each of solution D; the antagonism at M is ON + MN. tions or by the method of keeping the concentration of onesalt constant while varying that of the others, the dottedline would become a curved one. If we mix such solutions as NaCl M and M the antagonism curve resembles the one in Fig. , however, we reduce the concentration by one-halfthere will be less toxicity and in consequence the antag-onism will appear less pronounced. In order to illus-trate this, curves have been prepared which are diagram-matic composites of the curves obtained by the useof several pairs of salts; these composite curves are shown 136 INJURY, RECOVERY, AND DEATH in Fig. 56. For the sake of simplicity they are representedas having been obtained by the use of one pair of salts,which are designated as A and B. The curve CDEy there-fore, represents diagrammatically the growth of roots.

The abscisscT. represent molecular proportions; thusthe point G represents a mixture in which the dissolvedmolecules are 75% A and 257o B; the point // a mixturein which the dissolved molecules are 50% A and 50% B.
