Vi^o and indicate relative rate of outward and inward osmosis re- spectively (22). ment was carried out about 25 hours after the first. When the rate of osmosis in the two directions, in terms of percentage volume change, was then plotted on the ordinate against time on the abscissa, graphs were obtained which are shown in the left half of figure 3. A gain of fluid in one compartment of the osmometer is plotted as a positive volume change; the nearly equal loss in the other compartment is plotted as a negative volume change. The first two sets of data for gain and loss of fluid were set equal to 100. All following readings were expressed as percentages of these original values. It can be seen that, up to about the 15th hour, outward osmosis (solid line) is faster than inward os- mosis (dotted line). From then on, the situation is reversed. When a similar experiment was carried out, except with both saline solutions poisoned by cyanide, it was noticed (fig. 3, right half) that the reversal in the rate of out- ward and inward osmosis had already occurred after about 3 hours.
