The intense interest which in recent years has centered about the problems presented by peripheral vascular disease has thrown into painfully clear relief the meager limits to present knowledge of the nature of these maladies. Particularly is this true of the more obscure presenile peripheral arterial disturbances. Clinician and experimentalist alike appreciate the blindness of the fight being waged with thrombo-angiitis obliterans.
