抄録

The sections of the salivary gland chromosomes of Drosophila virilis made by means of supersonic vibration, and treated with the silver impregnation method and examined with the electron microscope show minute structures of chromatin bands and interchromatin bands of the chromosomes. The chromatin band is composed of a multitude of chromomere granules; the interchromatin band appears cocoonshaped or irregularly oval in shape, and contains 64 pairs of chromonemata embedded in the opaque matrix.
