The numerical solution of the low-temperature behaviour of the suscept
ibility of the spin-S antiferromagnetic chain is presented starting fr
om the exact thermodynamic Bethe ansatz equations for the Takhtajan-Ba
bujian model. It is found that the susceptibility for the several valu
es of S tends to its zero-T value with infinite slope, extending previ
ous results obtained by Eggert et al for the S = 1/2 case.
