IN THE preceding paper, the results of the experiment made by White and Black to test the validity of the inverse yield-nitrogen law were put in proper perspective. Obviously, the inverse yield-nitrogen law has survived the test, and in so far as this "law alone is concerned, the discipline of quantitative agrobiology has suffered no discredit. Invalidation of the inverse-yield nitrogen law would of course do away with the formula Q = 318/n, and with it the whole Mitscherlich-Baule-Willcox system of agrobiologic mathematics. Having, as they mistakenly think, disposed of the inverse yield-nitrogen law, they might have stopped there, but they go on with an effort to show that the procedure used by Willcox to derive the agrobiologic nitrogen constant 318 does not make plant-biological sense. The reader will recall that the mathematical discipline of quantitative agrobiology is compounded from two general natural laws of the plant
