Though - and here we have one of the many glitches of a reader's life (motto: "Many people say that life is the thing, but I prefer reading." Logan Pearsall Smith) - I've only encountered vermilion in text form: I don't actually knows what it looks like. To the Googlemobile, Robin!
Similarly, I have read over and over without question descriptions of the beautiful song of the lark; not living in Europe, I I've never heard it. A few months ago, the issue having somehow come up in conversation, I went to Google and found it here - or, as someone else puts it, rapid buzzes, whistles, and trills, not musical, not melodic, and utterly mystifying as to its chokehold on the romantic poets.
Unless it's just me.
Is Logan Wolverine's first name or his last?
