Reply To: letter indicator or not?
I would use caution with the Instruction Manual for Braille Transcribing ... it is NOT a rulebook, only a guideline. And ... thus far, I have yet to find an instruction manual without errors. In the items you listed below, it is very evident to me, that Methylcyclopropene is not a number. But you did ask what the rule stated. Perhaps a phonecall to Jennifer Dunnam can provide you with a better answer. Let me know what she says. 🙂
