Spectroscopic measurements of the strength and direction of transverse magnetic fields in six δ-spots are presented. The field direction is determined by the relative strength of the π- and σ-components at different polarizer orientations, and is, with one exception, parallel to the neutral line and as strong as the umbral field. Field strengths determined by line splitting are as high as 3980 G.
