• A cell culture from thoracic cord meningioma tissue obtained at surgery was maintained for several passages in cell culture. These cells spontaneously released particles with an RNA of highmolecular weight (90S to 95S) and a density similar to that of type C oncornaviruses. The implications of these results and similar findings by others are discussed.
