MONKEY, n. An arboreal animal which makes itself at home in genealogical trees.
MIND, n. A mysterious form of matter secreted by the brain. Its chief activity consists in the endeavor to ascertain its own nature, the futility of the attempt being due to the fact that it has nothing but itself to know itself with. From the Latin mens, a fact unknown to that honest shoe-seller, who, observing that his learned competitor over the way had displayed the motto “Mens conscia recti,” emblazoned his own front with the words “Men’s, women’s and children’s conscia recti.”
