AS PART of an extensive study1 of neurocirculatory asthenia, in which many methods of examination were used, the capillaries of the nail fold were examined in 48 patients with neurocirculatory asthenia2 and in 44 normal controls. It has long been known that persons with peripheral vascular disease have abnormal capillaries that can be seen in the nail fold and that in certain cases of mental defect,3 "vasomotor neurosis,"4 epilepsy and migraine variations from the normal capillary picture occur.5 Recently Hauptmann6 has thoroughly reviewed the literature and has shown that in many patients with psychoneurosis, especially anxiety states and hysteria, the capillaries are abnormal. He has helped us in our study by showing us his material, by advising as to our technic and by making photographs for us.
With the 92 persons included in this study the usual procedure was to examine the nail
