A case rather confusing to the practitioner, yet highly interesting because of its comparatively rare occurrence but far reaching effect, is that one of a young child brought to me for examination by Dr. Burnett.
—E. P., aged 4 months; Italian. The infant's mother and father were alive and well. One sister of the patient, 18 months old, was enjoying good health. The mother had had no miscarriages, the father denied specific infection and there was no history of tuberculosis in the family.The child was born after a period of normal gestation and after an uneventful confinement. Labor was easy and of short duration, no instruments were used and there is no history of trauma. He had been fed on the breast and, with the exception of an occasional vomiting spell, which the mother attributed to "too much milk," the infant had had no grave physical disturbances.The
