It appears, according to Collins, that he had obtained some work the night before, and had quit work about 6.30, whereupon he stepped into a barroom, took one drink of whiskey, left the barroom, walked down the street, and suddenly lost track of the world, coming to consciousness in a carriage with two policemen, but remaining, as he said, “dopy,” inattentive, and confused. After a meal, however, the patient began to feel better and soon felt quite all right. The =physical examination= was quite negative except that =neurologically= there was lingual and manual tremor, a speech defect, apparent only with test phrases, unsteadiness of handwriting, left knee-jerk greater than right, a left-sided Babinski reflex, and a difficulty in executing rapid successive movements (dysdiadochokinesis). This degree of neurological disorder in our experience warrants lumbar puncture as well as a serum test. The lumbar puncture shortly disclosed a positive globulin and excess albumin, and the returns from the W. R.’s were positive for both spinal fluid and blood serum. The data of the gold sol reaction were not available on account of technical difficulties. However, it appears that the diagnosis of neurosyphilis could hardly be avoided in this case. David Collins differs from Francis Murphy, then, in showing a positive blood and spinal fluid reaction for syphilis as well as a positive globulin and excess albumin. As above remarked, it is probable that the positive globulin and excess albumin would not warrant more than a suspicion of neurosyphilis taken by themselves. Unfortunately, we were unable to persuade the patient to submit to treatment, and from the patient’s point of view possibly his decision, not to submit to treatment, was a good one since he has had no symptoms of any sort for a period of 18 months since his episode. However, as abundantly elsewhere demonstrated, we feel that the patient is wrong, and that the physicians are right in urging treatment.
