Let us now consider a second category of possibilities, namely 
P °A< P °B Which CaSG We WiH CaU Chief tJPe 11 
We again distinguish three possibilities, viz. 
a. maximum pressure in the three-phase line 
b. minimum » >» ” ** ” 
e. no max. or min. » » ” ” ” 
1. will be superfluous to repeat the previous arguments when we 
examine the initial directions in the equations (3) and (3to). The 
conclusions arrived at are that we require for. 
Case Ila: a melting diagram with closely joined branches at the 
side of the component B, and but slightly differing triple-point 
Pr ZTro: a melting diagram with closely joined branches at the 
side of the component A, and but slightly differing triple-point 
P “ic will be again the intermediate case between the two 
previous ones; a concave (lie.) and a convex (lie.) course will 
again be possible.
