| Summary: | The data on the diamagnetism of carbons are reviewed. The thermal variation of the susceptibility is well represented by the relation:

in which

0 and θ are parameters. The values and the meaning of these parameters are discussed. A method is given for the mathematical representation of the experimental data
\

gc = f(

, taking into account two imperative conditions: the parameters must be determined by using the graph

. These conditions lead to a revision of the values of the parameters previously published and thus to a re-evaluation of their meaning. |
