Susan, I ran into this earlier in the year prepping for delivering workshops in June/July. I will see if I can contact Jan Smits to see if he can shed some light. Hopefully it has just moved, and is not gone altogether, because its an excellent resource.

Hey all, I was talking about scale and mentioned Jan Smits' excellent web page for older units of measure but when I went to the link I have I got the dreaded 404 message. Doing a quick search in Google and Yahoo pulled up nothing. I couldn't find it on the library's web page (but then I don't read Dutch). Does anyone know where it went?
