We add that in I (p. 779) the value p= 1 — -L was found in 
600 
the minimum E y which corresponds with a value of <p somewhat 
greater than 186. In the point D we found /?= 0,0267, to which 
belongs a value of <p only little higher than 173. As in the points 
C and B the values of v were found resp. 1,063 and 298, the 
corresponding values of ip are resp. somewhat smaller than 8 and 
somewhat larger than 0,0017. 
8. In this we meet with an important question. Towards what 
limiting values will these maxima and minima converge, when T 
approaches to 0? 
Though, namely, the possibility exists, that for exceedingly low 
temperatures factors come into play, which have not been reckoned 
with in our equations, yet it does not seem to me to be devoid of 
importance, to ascertain what follows from these equations for the 
limiting case T= 0. 
In the equation (3), viz.: 
f- 1 /. 
1-0* ^ * 
£ will soon approach 1 for values of <p > *, in consequence of the 
great increase of the exponential factor; while for values ofy<i, 
for which the exponent becomes negative, p will rapidly approach 
to 0. 
The great change of (i from 1 to 0 between E and D, which 
determines the minimum at E and the maximum at B, takes there¬ 
fore place for values of <p, which lie in the neighbourhood of 
For T= 9° we have - = —^— = 178, and now we really 
found (pE~ 186 and <p&= 173. As now according to (a) 
0 RT 
we shall evidently have <p E =<p D = od for T=z0, and this value 
will be determined by y = i so that we have:
