Chris,
> Hmmm, Peter, my copy of the British patent specifies methyl; however, it is patent 20,740. I actually have about five copies of Gateau patents. The only one that says metallic is this Google one. I wonder if Google's scanner does automatic spelling correction :)

You can download pdfs of US, GB, FR, AT and CH patents from
http://worldwide.espacenet.com/advancedSearch?locale=en_EP
with "Jacques Theodore Ggateau" in the "Inventor(s)" field.
Metallic violet is in the US patent, and methylic violet in the GB one.
