Escuan, I hope you're right ! The problem with ambiguity that Dryden was remarking on earlier - the preamble requires the 'modern, scientific way', which I believe is alphabetic, and the instruction suggests another way. If you've chosen the latter, then there are again 2, possibly 3, cases of a choice needing made. Most of the representations in the latter group aren't very modern, but are accepted by modern science...
Barretter, yes - it's just SAN(E)D. It might well be glasspaper, but the verb to glass means something else.
