“
The Insanity of the critical period of life is a form very familiar to us ; and I have no doubt you have recognised a critical period in the male sex as well as in the female, — a period of life at which, in many men, great disturbance of the normal state of the feelings and emotions is experienced, in some instances amounting to an insanity of the same type as that generally met with in females at their critical period — namely, a monomania of fear, despondency, remorse, hopelessness, passing occasionally into Dementia. This variety I would designate as Climacteric Insanity. There is a form of Insanity common to females, different from Hysterical Mania, or Nymphomania, and which, I think, is commonly associated with Ovarian disease, sometimes with uterine disease, and of which one of the most common symptoms is a sexual hallucination, — the belief that certain persons visit them and co- habit with them during the night, and other similar delusions. This form might be denominated Utero-mania, or Ovario-mania. It is, I think, par excellence the Insanity of old maids.
