cit.) which lay the main stress on the thickness and the capacity of the double layer on the radius of the particle and on the ionic strength of the medium and neglect the changes in the distribution of ions on aggregation which appear to be more important than the factors just mentioned. [...] It would appear from the curves that the rate of cataphoresis runs somewhat parallel to the rate of coagulation and that none of the theories of cataphoresis is sufficient to explain these results of diverse character for the simple reason that in the theories of cataphoresis in presence of electrolytes no account has so far been taken of the equilibrium between the process of aggregation and de [...] The higher the stage of aggregation or perhaps the more closely and intensely the primary particles are held in the aggregate the greater is the percentage increase in the c. v. It is of interest to note that a possible explanation of the failure of Smolchowski's theory at concentrations other than those producing rapid coagulation consists in the inhibiting effect of an increase in the c. [...] 3. Moreover the variation of c. v. with time in presence of an electrolyte appears to depend on (i) the nature of the sol; (ii) the nature of the electrolyte added and (iii) the electrolytic content of the sol—conditions on which also depends the rate of coagulation of different colloids in presence of various electrolytes. [...] By shifting the tube in the latter therefore a measure of the opacity of the coagulting sol was obtained relative to that of the colloid diluted with water442 S. S. JOSHI AND S. S.
