coexistence p in the different points of the curve SM (see fig. 6 of 
the Plate) from the relation (16) in connection with (2) and the 
equation of state. 
With regard to T= 0, we have already found by another way 
in II (see- p. 35), that then 
{T = 0) p 6

For in the relation (2) on p. 26, viz. 
F _ cT ' /+1 RT 
0 will always be = 1 for T= 0, when (p + «/„*)(— &b) > q t 
(portion FE of fig. 5 on the plate of III; v is then constantly 
= 2 b t ). For then the second member = 0 X — o°* If on the 
other hand ( p -f % 2 ) (— Eb) < q 0 (part DC, where v is constantly 
= b x ; and part CB, where v increases from b x to oo), 0 will always 
be = 0 in consequence of 0 X «“* = 0. 
Along the portion ED of the isotherm, where changes from 1 
to 0 with variable v, (p -f- % 2 ) (—A6)— q 0 must necessarily be = 0, 
for else £ would have to be either =1 or = 0 according to the 
above. It is however easy to see, that the mentioned quantity with 
respect to T must be of the order RT log for then 
F _ oT 7+1 X __ eX '

which now remains finite for T = 0, and may yield different 
values of £ for different values of v. In the second member we have 
p -{- o/ B a = along the mentioned part ED, so that + 
has a constant value, and for every value of v corresponds a 
definite value of p. Formula (10) follows then immediately from 
rf 
p a = — - j' pdv. And as = v — ^ t ^ en ^ 
manently = 0, hence v = b = b x -f- p A b, so that £ may be found 
from 0 = (See also the 2“ d footnote on p. 120 of III). By com¬ 
parison of this latter expression for p with the above one the value 
of A, left undetermined just now, might be easily found.
