This is a vintage black and white engraving depicting a series of medical treatments involving electrical devices. The image is divided into two rows, each containing three panels. The top row shows three headshots of men, each with a device positioned near their head. The device consists of a vertical pillar with a glass cylinder and a metal arm extending towards the person's head. One man is shown with a candle nearby, suggesting the device may be powered or influenced by heat. Each panel is labeled 'Fig. 3', 'Fig. 4', and 'Fig. 5' respectively. The bottom row shows three scenes within draped beds. Each bed is enclosed by heavy curtains, creating a private space. In each scene, a person lies in the bed with the same electrical device positioned near their head. One person is covered with a veil. A small table with a bowl is visible near each bed. The beds are supported by ornate pillars and the curtains are heavily draped, creating a sense of enclosure and privacy. The style of the engraving is detailed and precise, typical of medical illustrations from the 18th or 19th century.
