A satisfactory purification procedure for oat necrotic mottle virus involved clarification of the plant juice by silver nitrate, followed by two cycles of differential centrifugation, and then rate-zonal density gradient centrifugation. The concentrate was finally passed through a column of agarose gel. Antiserum to clarified sap from virus-free oats did not react with the final preparation. A medium consisting of 0.1 m-sodium citrate buffer, pH 6.2, containing 0.5 m-urea, was suitable for the concentrated virus. The virus particles were filamentous with a diameter of 11 nm. and a normal length of 720 nm.
