I heard it quoted in an art history lecture on John Singer Sargent, because the lecturer was (justly) worried that his Californian audience might never have heard of the Boston Brahmins.
I later ran across it in the Oxford Dictionary of Quotations, with author and context provided, and the third line as Jerome remembers it. (Yes, I've besmirched my honor to double-check it.) Citation available on request.
