Silver-stained sections of nervous tissue were examined with an electron microscope. It has been shown that the developed silver is particulate. These particles are between 30-700 Å in diameter and in nerve-fibres they are disposed along the surface and inside the components of the fibre. When impregnated sections were developed in a glycine physical developer, the mean size of the developed silver particles increased with an increase in the time of development.
In silver-stained sections of human sympathetic ganglion, the silver particles were distributed throughout the cell, but were more densely aggregated in the cell membrane and the nucleus. Erythrocytes show a dense aggregation of silver particles throughout the cytoplasm.
