Dotage is that feebleness of the mental faculties which proceeds from oldage. It is a diminution or decay of that intellectual power which was once possessed. Itis the slow approach of death; of that irrevocable cessation, without hurt or disease, ofall the functions which once belonged to the living animal. The external functionsgradually cease; the senses waste away by degrees; and the mind is imperceptiblyvisited by decay. Owing’s Case, 1 Bland (Md.) 3S9, 17 Am. Dec. 311.
