Resumen:
We show that the second knee in the cosmic ray spectrum (i.e. the steepening
occurring at $E\simeq 4\times 10^{17}$ eV) could be related to drift effects
affecting the heaviest nuclear component, the iron group nuclei, in a scenario
in which the knee at $3\times 10^{15}$ eV indicates the onset of drift effects
in the lighter proton component. We also study the anisotropies resulting from
diffusion and drift currents in the Galaxy, showing their potential relevance
to account for the AGASA observations at $E\sim 10^{18}$ eV, before the
extragalactic component becomes dominant.
