Practical techniques for inducing and maintaining inhalation anesthesia with chloroform, ether, and anaesthol are presented, including mask configuration and gradual dropwise induction. Cautious administration and morphine premedication are recommended, with respiratory patterns and reflexes used to judge the surgical plane. Recognition and management of complications—cardiac and respiratory collapse, obstructed breathing from crowding, and reflex responses to surgical manipulation—are discussed. Airway measures such as breathing tubes, intubation, jaw and tongue maneuvers, oxygen, and artificial respiration are outlined. Advice on maintaining depth, when to stimulate, sequencing agents for different procedures, awakening, and postoperative distress completes the practical guidance.
