This extent is shown in Figure 228, taken five months after the accident, when the granulations had grown over the edge about an inch.

Figure 229 shows the surface of the wound, six and one-half months after the accident and three months after the applications of numerous skin-grafts.
Cases of self-mutilation may be divided into three classes:--those in which the injuries are inflicted in a moment of temporary insanity from hallucinations or melancholia; with suicidal intent; and in religious frenzy or emotion.

Self-mutilation is seen in the lower animals, and Kennedy, in mentioning the case of a hydrocephalic child who ate off its entire under lip, speaks also of a dog, of cats, and of a lioness who ate off their tails.
