“In order to make the matter more conclusive, she ordered to be brought from her cabinet a vessel containing cold water, which she held under my nose, telling me that it was the true _subjectum_ of science, distilled, as one might conclude, from female exhalations, which Flamellus terms corporeal vapour. With this she roused to the highest pitch my anxiety to thoroughly sound the mystery, as I had already seen hints of these properties in the writings of Sandivogius and other philosophers. I did not fail to use my utmost persuasion on every available opportunity to penetrate the secret of this _Lixivium microcosmi_. At last the favour was accorded me, and I ascertained that this holy _arcanum_ consisted in human breath, which was collected from this lady’s servant girls, and liquefied in glass instruments curved like trumpets. The water thus gathered was concentrated in retorts and other chymical apparatus, and was the very essence fixed of impalpable matter. “By means of this discovery, life may be easily prolonged over a hundred years, for this vapour of breath collected from maidens in trumpets, when distilled, becomes an elixir of life, and by the copious use of this concentrated vitality steamed down to an essence, man becomes interpenetrated with living energy capable of resisting disease and repelling the inroads of age.” If we consider that the substances we absorb into our bodies become part of ourselves, and that our systems are undergoing a perpetual assimilation of the particles taken into us and renovation thereby, so that every seven years we have totally changed our substance, it is evident that, in the words of a learned friend of Doctor Cohausen, “This entire Hermippus, since he lived over one hundred years, must have been completely composed of the transmutated breath and porous exhalations of little girls; so that his career must have closed by evaporation.” It is certain that men can live a long time on what they inspire, without eating; for the famous laughing philosopher Democritus, who lived to a hundred and nine, when near his death observed that his sister was depressed, and on inquiring the cause, ascertained that she had anticipated great pleasure by attending an approaching festival of Ceres, but that she feared his death would render it an infringement of etiquette for her to be present at the public festivities. Democritus consoled her by promising to live over the day. And, in order to extend his life the required time, he ordered her to keep warm bread poultices under his nose, that by constantly inhaling the nourishing vapours he might be preserved. When the festival was over he ordered the bread pap to be removed, whereupon he gently expired.
