Monochrome engraving of four side views of cetaceans from a natural history book, each labeled. Top, a male whale. Below, a male cachalot. Below, and depicted as a fish, a porpoise ("Porpus"). At bottom, a male dolphin. Below the image is printed "Printed for R. Phillips, 71 St. Paul's Church Yard." Impressions from printed text on opposing page have been transferred to this one, revealing the book of origin to be "The elements of natural history: chiefly intended for the use of schools and young persons".
