Seite 466 - I was neither feverish nor thirsty; my bodily and mental debility were excessive, and the pulse feeble and quick. In this state I breathed for near a minute and half five quarts of gas, which was brought to me by the operator for nitrous oxide; but as it produced no sensations whatever, and apparently rather increased my debility, I am almost convinced that it was from some accident, either common air, or very impure nitrous oxide. Immediately after this trial, I respired 12 quarts of oxygen for...
