Fig. 5 since the former were obtained by allowing the flasks to stand in the laboratory, the temperature of which was not constant within 2° or 3° during the time necessary for equilibrium to establish itself. The upper values are accurate, being taken in a thermostat. Attention has already been directed to the length of time necessarv at low temperatures for the establishment of equilibrium in these dilute solutions. Ostwald also notes this fact.' The dissociation of adsorption compounds by raisino^ the tempera- ture can also be shown in the case of gelatin and inorganic electrolytes, though complicated in this instance, by the passage from the state of hydrogcl to that of hydrosol. There is, however, as I find, no sudden change in passing from the one state to the other as regards conduc- tivity. If one warms a gelatin hydrogcl from 15° to 40° determining I.
