assumed Carpboso’s value, which is 45,6 atm., whereas Dewar found 
50, and Onszewsky and v. Wropinwskr on an average 56 atm. With 
pk = 53 156 would have been found for 4, instead of 191, in perfect 
harmony with the calculated value. 
In all cyclical compounds C = 75, i.e. in the core. But of course 
C again = 100 in the substitution groups CH, (in toluene and xylene 
e.g.). For H we find everywhere 14. 
The fact that the values which have been found for 0; for 
n-pentane and iso-pentane from Youne’s data differ as much as 11 
units, suggests that the constitutive influences should not be entirely 
neglected, even though they do not make their influence felt much, 
compared with the so much stronger additive influences.
