The minimum value of p for v =. 1,5 {<rp = 1), which amounted 
©nty to lO- 3 ^ for T= 9, has now already risen to 0,012 = 10~ 2 . 
From the approximate relation ——— = ~ = 27, which holds for 
B and C if p == 0 (see II, p. 33), we should find vc = 1,28 and 
vb= 24,9. And as v = 1 -j- — for p= 0, we have <pc = 1,8 and 
9>B= 0,021, while then the corresponding values of p are further 
Pc = — 930, pB = 4,0. So these approximate values agree pretty 
well with the exact values of the table. 
T= 128.
