The character of the cutaneous capillary structure in 1,100 schizophrenic persons was studied for the purpose of ascertaining whether a distinction can be made between the capillary structure in normal persons and that in persons with schizophrenia.1

Investigation of the role of the capillaries has for the most part been restricted to pointing out analogies between the balanced arteriovenous circulation and growth. Stricker,2 as early as 1865, described the structure and function of the capillaries; Rouget,3 in 1873, the developmental properties of the capillaries, and Ray and Brown,4 in 1879, the capillaries in relation to blood pressure. Since that time many studies on capillary function have been reported; for example, Aby5 discussed the effect of capillary function on circulation in the brain; Bremer6 wrote on the nerve connections of the capillaries, and reports continue to appear on the role the capillaries play in the
