    The author studies the dispersion of fluid particles (i.e. Lagrangian trajectories) in turbulent motion of fluid. By the method of higher dimensions, the effect of velocity distribution, differing from the Gaussian distribution, is investigated. The method allows to find higher correlations for which the non-Gaussian regime starts at different velocity correlation times. The behaviour of some stochastic characteristics is described in qualitative terms.
