Mary M., æt 14, was admitted into the Bristol Asylum July 15th, 1862. She is described in the case book as having a hydrocephalic cranium, measuring “24 inches in circumference, and 14 inches over vertex.” Trunk shortened and thickened; legs doubled up on the thighs, which were again slightly flexed on the abdomen. Quite unable to walk or stand, but could sit comfortably in a low chair. She possessed considerable intelligence; knew the name of the place from whence she came, and answered simple questions in a lively manner Had her bodily health and education have been well attended to, it is probable that she would have possessed a fair amount of mental power. She was dirty in her habits, but of a tractable disposition, and good tempered. During the year following her admission attempts were made to teach her to read, but without success; she, however, soon learnt to be cleanly in her person and habits.
