Interpretation of Results. 



There are two possible interpretations of the phenomena under discus- 

 sion. According to one, the undissociated mercuric chloride may be 

 supposed to combine with the undissociated part of the electrolyte, 

 forming an undissociated double salt, while according to the other, the 

 undissociated mercuric chloride may be supposed to combine with the 

 chlorine ion to form a complex ion. The following considerations at- 

 tempt to decide which of these is more probable.
