Elizabeth Keckley,
Behind the Scenes (Keckley) — Chapter 12
(1868)
“ Don't I know a monkey when I see it?" "No, if you say that is a monkey." "I do know a monkey. I've seen lots of them in the street with the organs. I know a monkey better than you do, 'cause I always go out into the street to see them when they come by, and you don't." "But, Tad, listen to me. An ape is a species of the monkey. It looks like a monkey, but it is not a monkey." ”
