wherein 2 has again the value, indicated in (4). Consequently we 
tind the following: when the curves must be situated with respect 
to curve (C) as is assumed in fig. 3, then the coefficients of the 
reaction-equations (1) and (2) must satisfy the conditions (5) and (6). 
Let us take still another example. In order to find from (3) the 
reaction with respect to e.g. curve (D,) we put: 
4d,—d', = 0 consequently A= ENE ((7)

In fig. 3 the curves (D,) and (D,) and the bundles (A), (B) and 
(C\ are situated on the same side of curve (D,) as curve (A,). The 
coefficients of the phases D, and D,, those of A,, A,..., B, B,... 
and C\, C,... in (3) must, therefore, all be positive. Hence it follows:

Further it follows from fig. 3 that the curves (2,), (D,)... and 
the bundles (2), (S) and (7’) are situated on the other side of curve 
(D,) as curve (A,). The coefficients in (3) of the phases D,, D,... 
must, therefore, be negative, those of the phases Zi, R,..., SS, 
and 7, 7... must, therefore, be positive. Hence it follows:

Consequently we find: when the curves must be situated with
