I have lately had under my care two cases of insanity occurring in twins, and it seems to me that it might be of interest to some of our readers if these cases were published. The patients were young girls, and between whom there existed a marked sympathy. Not only are they extremely alike in personal appearance, but in manner, style, and speech, so much so that at one time nothing would be easier than to mistake one for the other. This similarity obtained not only in their bodily development, but in their mental condition also, and on the authority of their mother I am informed that great sympathy existed between them even in their illnesses; whenever one of the girls suffered from an illness the other would be sure to have the same illness also. This was particularly noticeable on one occasion: one of the twins was at Scarborough and the other in York. The twin told her mother that she believed her sister at Scarborough was ill, for she herself felt an attack coming on. The two sisters had no communication with one another, but the suspicion of the twin in York was true. The twin in Scarborough had exactly the same attack as the one in York (bilious headache). So again when the elder twin (who was the first attacked with insanity) began to show symptoms of unsound mind, her mother came to me expressing the deepest anxiety for the younger twin, though at that time there was no symptom whatever of any mental disturbance, but, as the sequel shows, was only too well founded.
