Vascular responses to local cold have been studied in ten normals and ten subjects with Raynaud's disease by means of measuring the heat output simultaneously from two forefingers kept at different calorimeter temperatures. The heat release from the forefinger kept at 30° C, reflecting probably the general vasomotor tone, was much the same in both groups. In patients with Raynaud's disease the heat elimination from the forefinger kept at 19° C was heavily reduced in comparison with normal controls. The significance of these findings is discussed in relation to some hypersensitivity of the vessel wall to local cold.
