Abstract:	The average multiplicity in deep inelastic electro- and neutrinoproduction at large ω(ω～s/Q² + 1) is related in Feynman's version of the parton model to the average multiplicities in high-energy electron-positron annihilation and hadron-hadron scattering. The relation is: $〈n(s, Q^{2})〉_{eP},ν P ～ C_{e^{+}} e^{?} ln (Q^{2} M_{1⊥}^{2}) + C_{h} ln (ω ? 1)$ , where C_e⁺e^? and C_h are, respectively, the coefficients of ln(s/M_1⊥²) in the multiplicities from e⁺-e^? and P-P in to hadrons, and M_1⊥ is an average transverse mass.
