angle, wliifli is foniierl l\y the stable part of curve (2) and the 

 metastahle part of curve (J). 



It also follows immediately from tiie first and the second of the 

 reactions above, tluit curve (4) is situated at the left of (J) and at 

 the right of (2). Curve (4) is consequently situated between the 

 metastable parts of the curves (1) and (2), and reversal ly the meta- 

 stable part of curve (4) is situated between the slable parts of the 

 curves (i) and (2). This is therefoie drawn in fig. 4.

It follows also from the first two reactions that curve (5) is 

 situated at the left of (1) and (2). Consequently curve (5) is situated 

 within the angle, which is formed by the slable part of curve (1) 

 and the metastable part of curve (2). [Confer fig. 4]. This angle, 

 however, is divided into two parts by the metastable part of curve 

 (3), so that we have slill lo know the position of (5) and (3) with 

 respect to one another. We can do this with the aid of the third of 

 the reactions mentioned above; from this it appears viz. thai the 

 curves (1), (2), and (5) are situated on the same side of curve (3; ; 

 curve (5) is consequently situated on the left side of (3). therefore, 

 within the angle, which is formed by the stable part of curve (Ij 

 and the metastable part of curve (3). [Confer fig. 4]. 



We have used for the determination of the mutual position of 

 the five curves, the three first reactions only ; we see that the division 

 with respect lo the curves (4) and (5), which follows from the last 

 two reactions, is also in accordance with fig. 4. 



When we determine, in the way treated above, the partition of 

 the regions, we find this as is indicated in fig. 4.
