Evolutionary link between globular clusters and circumgalactic clouds.

The established by us possibility to consider circumgalactic clouds (CGCs) as the remnants of the parent clouds in which globular clusters (GCs) have been formed (Acharova & Sharina 2018) is based on a comparison of the following facts. First, the metallicities of CGCs at redshifts $ z -1$ coincide within the typical error of measuring the elemental abundances in clouds: 0.3 dex (Acharova & Sharina 2018). Second, a similar coincidence is observed for GCs and CGCs with $\rm [X/H] -1$ at redshifts $ 2
