Arabella Burton Buckley, The winners in life's race (1883)
“ Their friends the Howler monkeys, which also have grasping tails, seek the deep recesses of the forest and creep quietly from tree to tree until night comes, when hundreds of them at once will make the woods re-echo with their deep howling cry, which they produce by a special voice-organ in their throat; and with them come out the little Owl monkeys, which sleep by day in the hollows247 of the trees. These, with the various kinds of Saki monkeys, which cannot cling by their tails, but have fairly good brains and quick intelligence, make up the monkey population of America. ”
