You might know about chemistry, but you know nothing about welding. Arc
Eye (photokeratitis) is a UV burn to the cornea (often confused with the
much worse "flash" which is a UV burn to the retina).

Had you given those children Arc Eye you would have found youself in
court.

Oh for goodness' sake!

I'm glad I'm going away tomorrow.

David, I've saved your mail and shall reply when I get back.

Bye for now, off to wet and windy Wales, feeling virtuous because I've
weeded my bean plot..
