Curiosities of Olden Times
"Once, as I urgently besought her to do me the favour of disclosing to me this mystery, she began, after the manner of philosophers, to speak in similitude: she said the ens spirituale was that without which no man could exist. It was common to all, to rich and poor alike. Adam brought it with him out of Paradise, and in it lay a nourishing principle of life attenuated in water and exhaled in air. I will not refer to other enigmas, which she knew how to propound from the writings of philosophers.
"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.
