Dry mass of herpes simplex virus particles was measured by quantitative electron microscopy after isolation by surface spreading and critical-point drying of infected cells. The core weighed about 2 x 10-16 gram, the empty naked capsid 5 x 10-16 gram, the full naked capsid 7 x 10-16 gram, and the enveloped nucleocapsid 13 x 10-16 gram.
