first a point of maximumpressure and afterwards a point of maxi- 
mum temperature. 
The hydrate // however may be situated also as in fig. 5; curve 
aqmb of this figure represents the solutions, saturated with MH under 
their Own vapourpressure ; the solutions of the dotted part ding are then 
metastable. Now we have the following singular equilibria : 
(M= lee + G [Curve (M) fig. 6] 
(L) =lee+G-+H [Curve (L) fig. 6] 
(7)=—lee+G+L_ [Curve (#) or qt in fig. 6 and gt in fig. 5]
