1956, Victoria Sackville-West, Even More For Your Garden (page 102)
"Might I now add a plea for the smaller irises, the tinies? They, also, should be divided up and replanted just now."

I've found that "tiny" is a noun, and I'd like to write something like "the difference is in the tiny." I include the period to make clear that's the end of the sentence. Does this make sense? I want to use this as a synonym for "microscopic".
