"Haslam considered the enlarged second edition... to be his magnum opus; it remained a standard work for several years. This edition includes an illustration of Haslam's infamous "key," an instrument used to force patients' mouths open to receive food, medicine, etc.; the key was intended as an improvement to earlier methods of artificial feeding, as it preserved the patients' teeth."—Hook & Norman.
