But the greatest danger I ever underwent in that kingdom was from a monkey, who belonged to one of the clerks in the kitchen. . . . [R]eaching one of his paws in at the door, as a cat does when she plays with a mouse . . . [he] seized the lappet of my coat . . . and dragged me out. He took me up in his right fore-foot, and held me as a nurse does a child she is going to suckle, just as I have seen the same sort of creature do with a kitten in Europe; and when I offered to struggle, he squeezed me so hard, that I thought it more prudent to submit.
