I thought though that I'd tried to suggest what the items found in, as Donal puts it, 'the other, presumably _smaller_?, class,' might be, viz., genuine names: 'Donal,' 'molybdenum,' etc. Why these?

Not sure about rebuses though. ------------------------------------------------------------------ To change your Lit-Ideas settings (subscribe/unsub, vacation on/off, digest on/off), visit www.andreas.com/faq-lit-ideas.html
