caption: The image shows a paper with a cartoon depicting a man in a lab with a skeleton in the background. The man is wearing a lab coat and a hat, and is standing in front of a large metal object. On the right side of the paper, there are several bottles and other objects on the shelves, and on the left side, there is a door. The paper also contains text, likely describing the hygienic system of James Morrison, exposing the use of poisons and other mysteries of doctor-craft.
