Samples of human milk from 59 women have been partially purified by highspeed density gradient ultracentrifugation. Pellets prepared from partially purified density gradient fractions have been examined by thin‐section electron microscopy. Virus‐like particles closely resembling various stages of the murine B and C‐type RNA tumor viruses have been seen in samples of milk from nine women.
