Three full doses of Kharsivan freed him from delusions and left him apparently absolutely sane. It was recommended that he should be kept at Haslar to continue treatment. However, he had been certified insane and was therefore sent to Yarmouth, from which he was discharged in February, 1917, having been in good mental health throughout his stay there. _Re_ syphilis and general paresis of military officers, as in Cases 1 and 2, Russo-Japanese experience was already at hand. Autokratow saw paretic Russian officers sent to the front in early but still obvious phases of disease. These paretics and various arteriosclerotics, Autokratow saw back in Russia in the course of a few months. _Re_ naval cases, see also Case 5 (Beaton). Beaton thinks that monotonous ship duty, alternating with critical stress of service, bears on morale and liberates mental disorder. Neurosyphilis may be aggravated or accelerated under war conditions. =Case 3.= (WEYGANDT, May, 1915.) A German, long alcoholic and thought to be weakminded, volunteered, but shortly had to be released from service. He began to be forgetful and obstinate, cried, and even appeared to be subject to hallucinations. The pupils were unequal and sluggish. The uvula hung to the right. The left knee-jerk was lively, right weak. Fine tremors of hands. Hypalgesia of backs of hands. Stumbling speech. Attention poor. It appeared that he had been infected with syphilis in 1881 and in 1903 had had an ulcer of the left leg. The military commission denied that his service had brought about the disease. =Case 4.= (HURST, April, 1917.) An English colonel thought himself perfectly fit when he went out with the original Expeditionary Force. He had had leg pains, regarded as due to rheumatism or neuritis. He was invalided home after exhaustion on the great retreat. He was now found to be suffering from a severe tabes. He improved greatly under rest and antisyphilitic treatment. He has now returned to duty. =Case 5.= (BEATON, May, 1915.) An apparently healthy man, serving on an English battle-ship, severed a tendon in a finger. The injury was regarded as minor. The tendon was sutured and the wound healed. During the man’s convalescence he was accidentally discovered to have an Argyll-Robertson pupil and some excess reflexes. Neurosyphilis had probably antedated the accident. But from the moment of this trivial injury, the disease advanced rapidly. Overwork in service; several months exacting work well performed: General paresis. =Case 6.= (BOUCHEROT, 1915.)
