1930 28 128) have st udied the coagulation of thorium hydroxide sol during the progress of dialysis of the sol and have found that the purity and the concentration of the colloid are necessary factors in determining the autocatalytic nature of the coagulation process. [...] The mixture (eleetrolyte -+ water) was added to the colloid by gently pouring it down the sides of the test tube and the time of mixing the electrolyte with the colloid was noted. [...] The values of t for the same stage of coalescence when different amounts of the electrolytes are added to the same volume of the sol have been obtained from the coagulation velocity curves for A " sole and the ratios --17 2' eta. [...] 1 to 3 that the coagulation velocity curves for " A " sol dialysed for 4 days are S-shaped and that the S-shaped tendency of the curves for the same amount of the electrolyte becomcs less and less with an increase in the dilution of the sol. [...] It has furthermore been shown that the nuclear nitrogen atom of the benzthiazole complex is the centre: of unsaturation of the molecule and that the sulphur atom of the heterocyclic ring rsembles that of thiophen in its inertness towards ordinary reagents; duo presumably to the fact that its labile electrons are called upon to complete the sextuple group on which the aromatic character of such
