Purple Hektograph Ink.

To make the purple hektograph ink:—Dissolve 1 part of methyl-violet in 8 parts of water, and add 1 part of glycerine. Gently warm the whole for about an hour, then allow to cool and add ¼ part alcohol. It is said, on good authority, that the alcohol may be advantageously omitted, and that the following proportions will give even better results than the above, viz: Methyl-violet, 1 part; water, 7 parts; glycerine, 2 parts. This formula, it is said, produces an ink which is less liable to sink into the paper.
