As a preliminary to his main work Bluhm has investigated the basal metabolism and the minute volume of cardiac output in tuberculous patients. The body of the report deals with a functional test of the lungs and a comparison with readings for vital capacity in the same cases. The history, technic and material are discussed under each heading. Brief histories of all the patients are given, and results are tabulated in detail and with numerous charts.
In determination of the standard metabolism, the oxygen consumption was measured with Krogh's apparatus and converted by use of the tables of Harris and Benedict, using plus 15 per cent as the upper limit of normal. In 40 ten minute and 411 five minute tests on a variety of tuberculous patients, some under treatment by different types of collapse therapy, Bluhm found a normal standard metabolism independent of the activity, the extension and the
