Mascart has found for nitrogen the following results: 
a) A 
— 5,085 . . . 
. v = 1,0002994 
b) 
5,378 . . , 
2986 
c) 
5,896 . . . 
2973 
d) 
6,438 . . 
2966 
From (a) and (d) 
. . . A — 4,09 
. . . 
(b) and (c) 
3,78 
Importance cannot be attached to the following data, given by 
L. Lorenz, as they are not the outcome of direct experiment: 
a) X = 5,893 ... v = 1,0002960 
b) 6,708 . . . 2951 
from these we find: 
4 = 2,35. 
Some of ScheeFs measurements are shown in the following table: 
a) X = 
: 4,358 . . . 
V = 1,0003020 
b)

From 
(a) and (i) 
... A = 3,88 
(b) and (h)

(c) and (g)

From ScheeFs values of the constants a, b 
a = 2906,1 .10~ 7 ; b = 22,47. 10r* 
we obtain 
D — 5161,6; A = 3,99. 
Let us adopt this value of D; then from ScheeFs consecutive data 
we obtain 
a) A = 3,70 b) 4,10 c) 3,88 
g) 4,05 h) 4,27 i) 3,40 
d) 3,92
