Abstract
THE method described by Hirst1 for the estimation of the hæmagglutinating activity of influenza virus suspensions and its modifications depend on gravity as the main operative force, which either determines the degree of clearance of the suspensions1, or promotes the development of typical patterns at the bottom of the tubes2.
