There exists a close relation between net preserving power of sulphur colours and the amount of dye-stuffs fixed (correlation coefficient=0.85). When the dye-stuffs are fixed above 4% or below 1% to the twine, in this experiment, the net preserving power is determined chiefly by the amount of the fixed dy-stuffs; and between these limits effects of differences in anti-septic power and in solubility among the dye-stuffs are notably observed.
