Abstract
THE polarization of the solar corona was determined from plates obtained in the 1932 and 1934 total solar eclipses. These eclipses were observed under perfect atmospheric conditions. Polarigraphs, equipped with quartz Wollaston prisms and colour filters of narrow transmission ranges, were used. Intensity squares were printed on each corona plate for photometric reduction. The plates were measured with the Hartmann microphotometer of the Lick Observatory and the Zeiss microphotometer of the Physics Department, University of California.
