It is a matter of great importance to distinguish appearances in dead tissues which are merely artefacts resulting from necessary chemical procedures and staining reactions, and it becomes necessary to examine tissues in the living state, a Matter of great technical difficulty.

Abstract

IMMENSE knowledge has been accumulated about the minute structure of organisms after death, while relatively little is known about the organisation of cells and their inclusions in the living state. It is a matter of great importance to distinguish appearances in dead tissues which are merely artefacts resulting from necessary chemical procedures and staining reactions. It becomes necessary to examine tissues in the living state, a matter of great technical difficulty.
