I had never noticed anything I considered too non-specific until the other day.
"and to this was added 10mL of sulfuric acid and 20mls of formaldehyde with stirring at 5-10C"

Rather ambigious whether both are added separatly simultaneously, as a mixture, or one after another. Adding one after the other makes more sense, but the wording is unclear.

Ah, well, ambiguous wording plagues all written media. :(

Oh yeah, I remember now, I have seen the word "several" in many a lab procedure, e.g. "several aliquots" or "washed several times with solvent X".

I take that to mean two or three, non-critically.
