Re: ferri sesquichlorati

Thank you, Neil!  Yes, this is in a book from 1900, so it is
an old term.  It is a gum process wherein you include this
in the gum mix!  I was going to give it a go.  But I guess I
don't have ferric chloride so it'll have to wait.  I do have
lots of FAC.

Sometimes it is such a pain figuring out how to translate
old chemistry terms.
