    figures with observed ones is of a greater use and clearness. But we can proceed more simply by putting y = \og z, i.e. plotting log z as a function of t, in which case we get a straight line (the continuous line in Fig. 2), beginning at the point y0 = log z0 = log 100= 2 and cutting the /-axis in the point log z 20 16 1 Logz 12 08 04 Fig. 2. = 0, i.e. % — i, and 2—0 = bt0, i.e. — ijb (in Fig. 2 /0= 20-6, t0 lies so far to the right that it does not appear in the figure). Here the value of b is very simple, namely, ^=2//0, b is the so-called velocity of reaction, it is equal to 2 divided by the time in which the quantity of cane-sugar has sunk to one per cent of its original value. Evidently the shorter the time for decomposing 99 per cent
