title: Optical ActivitY in the Orgueil Meteorite.
abstract: Nagy's report of an optical rotation of-0.023 degrees to -0.084 degrees in the Orgueil meteorite has not been confirmed. The highest rotation found in several fatty-acid and hydrocarbon fractions isolated from the meteorite was -0.002 degrees , less than that of optically inactive controls. The "rotations" observed by Nagy may have been caused by scattered depolarized light from colloidal particles, reduced instrument sensitivity due to low transmittance of the solutions, or a combination of both.
