This is a black and white illustration depicting a man in a laboratory setting. The man is shown in profile, wearing a long lab coat and trousers. He has dark, curly hair and a beard. He is holding a small bottle or flask in his raised right hand, as if pouring or examining its contents. His left hand is on his hip. Behind him is a long laboratory table covered with various pieces of equipment, including bottles, flasks, beakers, and test tubes. Some of the equipment is connected by tubing. A shadow is cast on the floor beneath the table and the man, created by dense, short lines. The style of the illustration is reminiscent of a historical engraving or sketch, with detailed linework and a focus on capturing the scene's atmosphere.
