Abstract
RECENTLY, Chou and Bradbury1 have pointed out some optical artefacts produced in the appearance of fat droplets under the phase-contrast microscope. They say that homogeneous fat droplets may have a “crescentic” appearance if examined in a non-axial light source or an eccentric condenser. They also point out that in a fully centred system the appearance of such a fat globule is a “perfectly symmetrical sphere with a dark rim or apparent ‘cortex’ surrounding the bright region within”.
