I seem to remember from reading a book many years ago, maybe around
fifty years ago, something about one of the early chemists (Lavoisier?)
having used two symbols, each a spiral, mirror images of each other, for
two different things, maybe oxidation and reduction, in his manuscript
but he had had to abandon the idea because when he wanted his text
printed the printer did not have any metal sorts of a spiral and so he
had to use some other format.
Does that ring a bell with anyone please?
I remember that where I read it that there were two spiral motifs
displayed in the text.
At the time I was already into Private Press Printing using letterpress
on a handpress using metal type and producing designs using single type
border sorts, so that is perhaps why that has remained in my memory
