This black and white image depicts a medical teaching scene, likely from the early 20th century. A patient lies on a bed covered with a white sheet. A doctor, dressed in a dark suit, is bending over the patient's arm, presumably demonstrating a medical procedure. Around the bed, a group of men, likely medical students, are observing. They are also dressed in suits and appear attentive. The room is decorated with anatomical charts and diagrams. A full-body skeleton is visible on the left, and various charts depicting the human anatomy are hung on the walls. In the background, there's a table with medical equipment, and a chandelier provides lighting. The overall atmosphere is formal and educational, typical of a medical lecture or demonstration. The caption at the bottom reads "Fig. 15. - RAISING THE BRACHIAL ARTERY."
