[13] Many years ago I communicated to my friend, Dr. Percival, an account of some trials of breathing fixed air in consumptive cases. The results were published by him in the second Vol. of his very useful Essays Medical and Experimental, and have since been copied into other publications. I take this opportunity of acknowledging that I suspect myself to have been mistaken in the nature of the disease there mentioned to have been cured. I believe it was a case of Vomica, and not a true Phthisis that was cured. The Vomica is almost always curable. The fixed air corrects the smell of the matter, and very shortly removes the hectic fever. My patients not only inspire it, but I keep large jars of the effervescing mixture constantly at work in their chambers.
