Here, then, we seem to have evidence of an inflammatory process of the central nervous system, and it is natural forthwith to be sceptical as to the accidental nature of the gas poisoning. Perhaps there was an attempt at suicide based upon a passing impulse, or perhaps there was a period of confusion in which the cock was not turned off. In any event, we feel justified in making the diagnosis of cerebrospinal syphilis on the basis of the neurological and laboratory findings. On the whole, we are inclined to make a diagnosis of VASCULAR NEUROSYPHILIS with a moderate involvement of the MENINGES. 1. What is the outcome in such cases as that of Annie Monks? The case somewhat resembled that of Martha Bartlett, who still survives. The case of Annie Monks illustrates another outcome. A few days after her admission, she became unconscious once more, and upon recovery remained very much confused and aphasic, moaning, and unable to handle herself well, although without definite paralysis. Three weeks later the patient died, although in the meantime strenuous antisyphilitic therapy was practised. Death was sudden. We thought death due to cerebral embolism. =Early delinquency and neurosyphilis in a juvenile.= =Case 86.= Frank Johnson was 21 years of age when he was taken up by the police for threatening his sister with a revolver. The police thought he deserved an examination at the Psychopathic Hospital. The patient protested that he had threatened his sister only to frighten her because, he said, she nagged him and made him nervous. In fact, they had always had trouble as she had always nagged him and they had always fought together. Moreover, their mother always took the sister’s part. They had been troubling him for days, and at last Frank could stand it no longer. His sister had complained of the way he treated her dog. Moreover, Frank said he had not been feeling well; there had been some trouble with his stomach; and after one of the nagging attacks, he had taken out an old empty pistol to scare his mother and sister. In these cases, it is good practice to consult the sister also. She said that Frank had always been very difficult to manage, unwilling to work, preferring to loaf about, spending every obtainable cent; he was once in a reformatory for several years, but not reformed thereby; recently given to drinking; at times acting somewhat peculiarly (sitting at the window with his hat on, refusing to move). Further =mental examination= of Frank showed that he was properly oriented and in possession of a good memory, although he was quite obviously a liar. He lay about in bed at the hospital, saying that he was too weak to be up. He was a bit dull, at times not readily grasping ordinary questions.
