The hypertensive group included 37 per cent of those aged under fifty, and 78 to 84 per cent of those in the next three decades of life at the time of the attack. All except one of the 20 female patients were hypertensives.

The average course of the blood pressure during ten years after coronary thrombosis (not including the first, month following the attack) has been plotted. The systolic pressure showed a slight rise during this period while the diastolic showed a slight fall. Evidence before the levels were exceeded.

A second case of Laennec cirrhosis of the liver, liver carcinoma, congestion of the systemic and pulmonary circuits in a fifty-five-year-old man is reported in which venous collaterals had been established between the portal vein, veins in the abdominal wall, and veins in the right side of t,he diaphragm. In addition venous collaterals were present betwen the diaphragm and the pulmonary veins of the adherent lung. L. N.

In general, there are four types of treatment of embolism: (1) Embolectomy, (2) the use of intermittent negative and positive pressure, (3) the use of vasodilators, and (4) symptomatic or “watchful waiting.“’ Embolectomy was successful in 4 out of 9 cases. Careful localization was made preoperatively, by means of palpation and the use of an aneroid sphygmomanometer. Negative-positive and negative pressure treatment was successful in 9 out of 13 cases. This is especially encouraging in that these eases were not suitable for embolectomy because of the poor condition of the patients. The average length of treatment necessary to establish an adequate One of the patients treated successfully circulation was four and one-half days. by means of negative-positive pressure had a large embolus occluding the bifurcation of the aorta and the arteries below the bifurcation. The author believes that early application of intermittent negative-positive pressures prevented formation The author has no of secondary thrombi in the arteries distal to the occlusion. data on the use of vasodilators, since he did not wish to complicate the results of the other methods of treatment. In only one of 13 cases receiving no treatment was the limb saved. Of 5 cases of embolus in the arm, 4 recovered with no treatment but these cases were not included because of the frequency of spontaneous development of collateral circulation in this extremity. The best results from a single method of treatment of embolus was suction and pressure therapy. The writer believes the ideal method of treatment for suitable cases is a combination of treatments, namely, embolectomy followed by use of the suction-pressure treatment and also the production of peripheral vasodilatation. In cases properly treated, a still higher percentage of extremities should be saved.
