Abstract
DURING the course of experiments designed to investigate the staining of nucleic acid in histological sections, I happened to gather together on one bench a number of solutions of basic dyes reduced to their colourless sulphite leucobase. These included methyl green, basic fuchsin and a series of thiazines, namely, thionin, azure A, B and C, and methylene blue (for a discussion of the structure of these thiazine dyes, see Baker1).
