It follows also tVoiii both the tii-.st i-eat'lious that curve (4) is situated 

 on the righthand side of' (I) and of (2) ; consequently it is situated 

 in fig. 6 witiiin the angle, which is formed by the stable part of 

 curve (1) and the nielastable part of (2). Within this angle, however, 

 also the mefastable part of the curve f3) whicii has already been 

 determined, is situated ; consequently we have yet to examine the 

 position of curve (4j with respect to curve (3). Tiiis follows from 

 the third reaction ; we know viz. already from the previous that (1) 

 and (2) are situated on the righthand side of (3) [in connection with 

 this the third reaction is written in such a way that iierein (1) and 

 (2) are situated at the rigiilhand side of (3j], so that (4) must be 

 situated at tlie left of (3). Hence it follows tiiat (4) is situated within 

 the angle, formed by the inetaslable paits of curves (2) and (3) 



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

 situated at the right of (1) and of (2); consequently curve (5) must 

 be situated within the angle which is formed by the stable part of (1) 

 and the mefastable part of (2). This angle is divided into three parts 

 by the stable part of curve (4) and the metastable part of curve (3), 

 so that we have still to examine within which of these parts the 

 curve (5) is situated. This appears immediately from the third reaction, 

 from which it is apparent that curve (5) is situated at the righthand 

 side of (3). Consequently curve (5) must be situated within the angle, 

 which is formed by the metastable part of curve (3) and the stable 

 part of curve (1). 



We have only used the first three reactions for the determination 

 of the mutual position of the live curves. The partition of the curves, 

 which follows from both the last reactions, is also in accordance 

 with tig. (3.
