Summary

  1. 1.

    Storage at 37° C induced varying degrees of impairing of the hemagglutination and infectivity powers of the strains of Newcastle disease and fowl-plague viruses used in this investigation.

  2. 2.

    The agglutination and infectivity powers of virus strains being tested were completely destroyed when exposed to 60° C for 5 minutes.

  3. 3.

    The hemagglutination activities of all strains of Newcastle disease virus used in this investigation were easily destroyed by high temperature than those of fowl-plague virus.

  4. 4.

    A certain property of a particular virus may be possessed by some but not by all of its strains.
