referred to us with a copy of an impartial report filed by the Massachusetts General Hospital,—we concur with said impartial report that there is now no evidence of paralysis of the arm. We do not find that the positive Wassermann reaction, although it indicates a history of syphilis, has affected the patient other than possibly to have reduced his general mental capacity. Our special tests yielded a percentage of 62% of what a patient of his age and station should possess. There seems, however, to be no connection between this reduction of mental capacity and the difficulty with the arm. We cannot connect the history of alcoholism with the arm trouble. “There is some evidence that other stone workers have at times shown such effects. “The patient’s fairly circumstantial account of his difficulty seems to point to a degree of myalgia or muscular pain in the region of the forearm when held in a certain position and a feeling of numbness in the third and fourth fingers. Whether these phenomena are due to local pressure upon nerves in the upper part of the forearm due to neuritis, or whether we are dealing with a functional neuralgic phenomenon is a question. “We have applied some special tests for faradic sensibility to all the fingers of both hands and have found that the fingers of the right hand are still less sensitive than those of the left, particularly the thumb and the little finger. This test has not yet been applied in a sufficiently large number of cases to prove any difficult point, nevertheless the findings are in line with the patient’s own circumstantial account of former feelings of numbness in the third and fourth fingers of the right hand. “Obviously, then, our opinion is that there is still to be found some effect of the disease, whatever it was, which caused the patient to knock off work. If we had more experience with such cases and more data with the new test which we have applied, we should perhaps be inclined to admit the diagnosis of _occupation neuritis_ and to suppose structural alterations in the nerve trunks corresponding with the location of the muscular pain and the anesthesia of fingers and the dulling of electric sense, but in the present stage of our experience, it is probably wiser to call the case one of _occupation neurosis_.” It is clear that the W. R. in this case was of peculiar value in at least partially clearing up the findings, yet it must be remembered that it is a principle of the modern administration of industrial accident boards and similar organizations that it is the employer’s lookout whether the employee has syphilis. Recovery can be made as if the injury were due wholly to an accident. It was not possible however definitely to prove or disprove a relation of syphilis in the form of a syphilitic neuritis to the condition in this case.
