data regarding the other systems are so scanty as not to allow of 

 any positive assertion on the course of the curves. The shape, which, 

 in our system, I consider probable, may even happen to be the 

 most usual. 



A further conclusion from this investigation is that systems, one 

 component of which is a member of a horaologue series, need not 

 belong to the same type of demixtion pltenomena. If we pass from 

 decane to hexane, the limited miscibility remains, it being connected 

 above all things with the chemical nature of the components, but
