    manometer, l)e noted suflicicntly early to allow time for the institution of preventive measures, directed toward the relief of toxemia, by increasinj^ elimina- tion. The l)lood-])rcssure durin<( an uremic attack may be far above v300 mm. Actually how high has not been recorded, because before the development of the Faught Clinical Sphygmomanometer no instru- ment was capable of recording pressures above 300 mm. In patients who are seen in emergency and are found profoundly unconscious, the sphygmomanomet- er will often be the means of separating the coma of uremia with high blood-pressure from coma of other origin. In Valvular Lesions.—In the study of the valvular disease of the heart the results do not seem to have special bearing upon the primary condition (defective valve) except in cases of aortic regurgitation. This is in part due to the usual complicated nature of the condition, which often includes arterial and myocar- dial changes and involvement of the kidneys. The chief value of the sphygmomanometer in the study of heart conditions applies to the condition of the myocardium, to a demonstration of the etTect of therapeutic measures and as a guide in prognosis and in the general management of cases. With it we are able to determine with considerable accuracy the bene- fit derived from the drugs and other measures em- ployed. In this we may guard against insufficient or improper treatment and also against the over-use of these same measures by demonstrating the therapeuti- cally efficient dose and the proper interval of its exhi- bition.
