High-temperature---low-field susceptibility series for the exchange-interaction model of ferromagnetism are analyzed by means of a reexpansion technique to obtain the ordering temperature. In particular, for all two-sublattice decomposible structures (e. g., linear chain, plain square, simple cubic, body-centered cubic) the formula kBTCJ=(12/5)(z-5/2)(4S+3)^-1 reproduces our numerical results.
