29.4 — 20,7 = 8,7.10- 
35,9 — 26,4 = 9,5 .10-2, 
hence for Sb on an average: 
Var = 8,9 X 10-2, 
in concordance with the expected value in the 4 horizontal row of 
the periodic system, which is about 9 x 10-?(1=— 8,8; X= 9,1;

The boiling point of Antimonium being 1440° C or1713° abs, 7%, 
will not be lower than 1713 x 1,7 à 2, i.e. + 2900°, so that at the
