Any more would be injurious...

I would like to know the origin and the rest of this phrase: "Anymore would be injurious to my supreme delicacy." My grandfather used to say it and his family is from England & Ireland. Thanks!

I don't know the origin of the phrase, nor its meaning, either. (What "delicacy"?) But I suggest that you insert a space between "any" and "more" for the sake of both meaning and pronunciation.
