According to the accompanying text, this illustration depicts a baboon species “easily distinguished by its tail, which is four inches long, slender, and exactly like a pig’s.” After some more physical description, the writer adds, “Though full of vivacity, it has none of that impudent petulance peculiar to the other baboons; but is gentle, tractable, and even caressing. It is found in Sumatra and Japan. In the latter country, it is taught tricks and carried about by mountebanks.”
