Now, if it be conceded that the main cause of consumption, tracing the disease back to its first cause, is to be found in an insufficient supply of oxygen to the system (which certainly the success attendant on the treatment based upon this theory would lead one to suppose), we would beg of our readers seriously to ask themselves how can consumption be cured by drugging, and how can the much required oxygen be supplied to the blood by any proceeding of the kind? We think that the results of such a system afford a conclusive answer to this question; failure marking its course wherever it has been tried. Again, as regards the fashionable remedy of going abroad, [10] how are we likely to get more oxygen supplied to our blood by going abroad than by staying at home? What magic is there in the process? A mild climate may certainly prove less irritating than its native air to a diseased and disordered lung, and the suffering and uneasiness consequent on the irritation may be thereby allayed, but we are not a whit nearer being cured by this device, nor have we, in so doing, properly gone to work to remove the main spring and cause of the disease. Let our readers bear in mind the following aphorism of Dr. Hall: “Close bed rooms make the graves of multitudes;” let them recollect that impure blood is the origin of consumption, and that impure air causes impure blood. Carrying out these principles, in curing consumption, Dr. Barter would use all means to place the system in a favourable condition to receive a full supply of oxygen, first, by a direct inhalation of a mixture of oxygen and atmospheric air through the lungs; secondly, by enjoining a large amount of active exercise in the open air, when practicable, and sleeping at night with open windows; and thirdly, by inducing a healthy action of the skin, [11] and consequent supply, through it, of oxygen to the blood, by the intervention of the Turkish bath. This mode of treatment has, we believe, proved most successful, whilst the old mode of treatment, of which it is the very antipodes, viz., keeping the patient in a heated and impure atmosphere, swathing him with flannels, [12] dosing him with prussic acid, and applying a respirator to the mouth, has proved most unsuccessful and fatal. How it could ever have entered into the brain of a physician to recommend the use of a respirator, as a cure for consumption, we are at a loss to imagine, as a more ingenious mode of shutting out the pure atmosphere, essential to our existence, and exchanging it for one loaded with carbonic acid (thus aggravating the disease which it seeks to cure), could not possibly be devised. Man, in a state of health, requires pure air as a condition of his existence; and can it be supposed that, in a state of disease, he will be able, more successfully, to resist the effects of poison on his system than when in a state of health? Will he, in a state of disease, be strengthened and improved by the loss of that, on
