of stimulation which the authors have not yet explored fully, such as various natural humoral substances, carbon dioxide, drugs, etc. Such an influence as that of oxygen on the ductus may have something in common with the findings of Figge (1934), who demonstrated a definite effect on the metamorphosis of the aortic arches and gills in larval forms of the salamander by variations in oxygen tension of their environment. If this seemingly important relationship of oxygen to the mechanism of closure of the ductus is true, it offers a practical indication for treatment of newborn infants, especially those which have difficulty in the oxygenation of their blood.

Of 771 consecutive autopsied patients dead of heart disease, 354 (45.9 per cent) had one or more infarcts in the lungs, brain, kidneys, spleen, extremities and/or intestines. Subacute bacterial endocarditis was the type of heart disease most frequently associated with infarcts of the viscera, 80 per cent of the cases showing this complication. In coronary artery disease with myocardial infarction, about GO per cent of the cases had one or more infarcts in the lungs, brain, kidneys, spleen, extremities and/or intestines. Coronary artery disease without myocardial infarction and rheumatic heart disease were about alike, approximately 50 per cent of t,he ca.qes showing one or more infarcts. The incidence of infarction in hypertensive heart and syphilitic heart disease was about 40 per cent, and t,his complication was uneommon in car pulmonale. The lungs were involved by infarction in 28.7 per cent of the 771 cases, the kidney in 17 per cent, the spleen in 11.7 per cent, the extremities in 2.6 per cent, and the intestines in 1.7 per cent. There was infarction of the brain in 17.6 per cent of 432 The highest incidence of infarction occurred in subacute bacterial examinations. endocarditis (kidney, 70 per cent; and spleen 66.7 per cent).
