SUMMARY The growth in tissue culture of a virulent epidemic type of I.L.T. virus, fully adapted to tissue culture is described. It has not been possible to demonstrate a one‐step type of growth, but it is apparent that the eclipse phase of this virus is relatively long, of the order of 18 hours, and is followed by rapid production and release of virus. A prolonged lag phase is noted in the one strain of low virulence examined. This is in keeping with the growth of such strains, as described by other workers.
