The Closed System.—(i) Ether only; (2) Ether preceded by nitrous oxide ; (3) Ether preceded by chloroform. THE OPEN SYSTEM. Till quite recently it was recognized as almost axiomatic, that the open system of administer- ing ether was useless except in the case of young children and debilitated adults. We now know that such an impression is quite erroneous, and that this very system, so long discredited, is in fact '' the ideal.' True, in certain cases, e.g., powerful muscular men and alcoholic subjects, a certain difficulty in inducing anaesthesia may be encountered, but even in the majority of these cases, a more enlightened knowledge of the means at our disposal enables us to minimise, if not entirely dispose of, difficulties.
