SUMMARY A number of arboviruses multiply in avian cells in tissue culture but fail to produce plaques in them when grown under an agar overlay. It has been shown that the addition of optimal amounts of DEAE dextran or of protamine enables some such viruses to form clear‐cut plaques to a high titre. The optimal doses do not inhibit plaque production by any arbovirus tested.
