Tidied up edit

I've tidied this up quite a bit. It looks like it was scanned in via OCR, as it was full of odd transcription errors. I'm not sure what the sentence "When obsidians are dcvii rifled " should really say. It still needs some work. StoatBringer 01:47, 11 September 2004

"translation of OCRtext edit

"When obsidians are dcvii rifled " should read "When obsidians are devitrifed".
