It will be apparent that the salt when dried in an air current, at about 20 C., 

 contains 14 of water, and not 15 as stated by ROSCOE and SCHORLEMMER.* 



The following table gives the results of the osmotic-pressure determinations, and 

 the figures in the columns have the same meaning as in the case of Table I. 



TABLE V. Strontium Ferrocyanide. 



Tabulating these results in the form given for the calcium and potassium salts, 



TABLE VI. Strontium Ferrocyanide. 



we get : 



In the case of this salt the observed osmotic equilibrium pressures are less than 

 those calculated from BOYLE'S law ; thus the peculiarity noticed in the case of the 

 calcium salt is emphasised in the strontium solutions. 



A search for a similar anomaly was made among such other salts of complex acids
