The new-formations in the inner meninges mostly belong to theconnective-tissue tumours, and are oftenest sarcomata. In these therenot uncommonly occur concentrically laminated calcareous concretionsresembling brain-sand (Fig. 37, h), which are probably formed by thecalcification of flat endothelioid cells arranged in strata like the coatsof an onion (psammomata). In the arachnoid of the spinal cord smallosteomata are frequently found in elderly persons, the development. A \ 4. -> d
