The change of life, or menopause, the cessation of the function of menstruation, usually occurs between the ages of forty and fifty. It sometimes occurs a little later, and sometimes as early as between thirty and forty. We have met one case in which it occurred before the age of thirty. The usual symptoms are irregularities in the times and quantity of the menstrual flow, various nervous symptoms, sudden flushing of the head and other parts of the body, congestion of the head, and disorders of the digestion, etc. During this critical period of her life a woman should have abundance of rest, freedom from care, frequent recreation, plenty of out-door exercise of a gentle character and mental diversion. Special attention should be given to the general health, and all the laws of hygiene should be regarded carefully.
