by me f— 1 and s* would become much greater than the value 
given for them by experiment. 
But the thus calculated value for stationary molecules is not what 
I have represented by dj; I should prefer to represent it by='6.,. 
At the point where the 6-curve meets the line which divides the 
angle between the v-axis and the b-axis into two equal parts, need 
not and cannot be the point in which 4 is equal to b,. The d-curve 
does not cease to exist in this point; it passes on to smaller volume, 
or possibly follows the line v = 0. 
On closer consideration the 6-curve appears ta touch the line v= 6d 
and at smaller volumes than that of the point of contact the value 
of v appears to be again larger than 6. 
In the same way as kinetical considerations were required for 
the determination of the value of 4, to show that 6, is equal to 
; : ; 1 
four times the volume of the molecules, and so equal to ard 
biim cannot be found without the atd of kinetical considerations. And 
the attempt which I make to calculate the value of bum, follows 
the same train of reasoning as has been efficient for the determination 
of 6,. This train of reasoning is as follows. If the mean length of

path for molecules without dimension is equal to yl , and if the

the value of B = Woe for Aj. So that, if we also introduce a

value v, = 6,, —— amounts to— 1,814. If we assume a regular

arrangement of the molecules in v, and vj, the distances of the 
centres are not equal to 2r in vim, but equal to 2r B-1,814 — 1,22 
times 27. 
But for moving molecules such a regular arrangement is perfectly 
improbable. For them no other rule is valid but this that within a 
certain small space of time in equal parts of the volume, if not in 
contact with the walls, the mean number of molecules is the same. 
But their arrangement in such an equal part of the volume is 
74°
