    plained the knowledge furnishes a basis for rational treatment. Diabetes.—The blood-pressure in diabetes is low, often being found below 100 mm. The chief value of the blood-pressure test in this disease is in the detection of complications involving the kidneys. A rising blood-pressure found in the course of a case of diabetes will direct the attendant's attention to the kidneys, when a urinalysis will often explain the origin of the turn for the worse. Cardiac Dilatation.—As would be expected, dilata- tion of the heart is accompanied by a dangerously low blood-pressure, which may be sufficiently low to endanger life. The finding of a low pressure in a cardiac case will plainly indicate treatment directed toward preventing syncope. Improvement in the condition of caridac contrac- tion will be shown by a gradually rising pressure, accompanied by a falling pulse rate and an increase in the pulse pressure. Shock and Collapse.—These are two complications which may develop under a variety of circumstances in many disease conditions. In many cases which are in an apparently good condition, the sudden develop- ment of one of these complications may result fatally. It becomes, therefore, of great importance to antici- pate the onset of these complications and, upon noting the warning signs, to institute measures for their relief. This form of procedure is in many cases very successful. During surgical operations under anaes- thesia the sphygmomanometer is of great service in detecting early circulatory failure from either heart failure or vasomotor paralysis. Many surgeons, among
