If the baryon is considered as composed of a bare spinor without charge or strangeness and the known meson fields (both pi and K), one may investigate the behavior of the lagrangian describing this model under an operation which reverses the sign of charge and strangeness of the mesons without altering the bare baryon (boson conjugation B) and an operation which turns the bare baryon into its antiparticle without changing the meson fields (spinor conjugation S), the product of these two operations being the usual charge conjugation C. It is found, when one neglects mass differences between nucleon and hyperons, that the lagrangian of this system is invariant for each of the three operations B, S. and C, separately. The same property is deduced also for the d'Espagnat-Prentki lagrangian of an assembly of real nucleons, hyperons, and mesons and for the interactions with the electromagnetic field of all these particles. Finally, it is suggested tbat the mass difference between nucleon and XI could be due to an interaction term in the lagrangian which should be invariant under charge conjugation but not under the B and S conjugations separately, and a simple proposal for such a term is made.
