60 minutes. The temperature was 21° + 1° C.; the concentrations 
of the solutions of salts used were consecutively varied from 0,1 
normal to full saturation. The complex salt used was carefully 
purified and did not contain any appreciable amount of cobalto-oxalate; 
moreover, the solutions were stirred by the aid of a current of 
carbondioxide, after it had been demonstrated, that this gas had no 
influence upon the speed of reaction. 
Above we have given a review of the results obtained, while in fig. 1 
these data are reproduced in graphs, in which the equivalent-con- 
centrations of the electrolytes added are used as abscissae, while 
the percentages of the original salt transformed, are taken as 
ordinates in it. 
The determinations with BeCl, and Fe,Cl, are somewhat less 
accurate, as a consequence of secondary influences, as e.g. the strong 
hydrolysis of the berylliumsalt, and perhaps the formation of complex 
compounds in the case of the ferric salt; by these factors the image may 
be somewhat less definite. The data obtained in these cases follow here :

$ 6. In these series of observations evidestly we cannot speak of 
real reaction-constants: the data available do agree neither with the 
supposition of a monomolecular, nor of a bimolecular reaction-form.
