The figures of the second row of the above table are the mean 

 of the Umiting values obtained from seven monovalent, six 

 divalent,, seven trivalent, four tetra valent and one haxavalent 

 cobaltammines as shown by table I. Unfortunatel}^, as the author 

 had not prepared a pentavalent cobaltammine, the figure is lacking. 

 But it is very easy to predict the limiting ^-alue of the pentavalent 



complex ions. By using the above equation, it should be , ^nqqqq 



for the sanie sol. 



The valency effect for the normal salts. 



In order to compare the results obtained b}^ the cobaltammines 

 witli tliose of the normal salts, the experiment w^as undertaken by 

 using the following salts and the same sol. Although the salts 

 were not widely selected, there was much deviation from the 

 theory as shown by the table IV, V, and Fig. o.
