Leaves, and these very strong and fragrant of the Odour of the Mint: but the Heat of my Chamber, as I suppose, kill'd the Plant when it was grown to have a pretty thick Stalk, which with the various and ramified Roots, which it shot into the Water as if it had been Earth, presented in its Transparent Flower-pot a Spectacle not unpleasant to behold. The like I try'd with sweet Marjoram, and I found the Experiment succeed also, though somewhat more slowly, with Balme and Peniroyal, to name now no other Plants. And one of these Vegetables, cherish'd only by Water, having obtain'd a competent Growth, I did, for Tryals sake, cause to be Distill'd in a small Retort, and thereby obtain'd some Phlegme, a little Empyreumaticall Spirit, a small Quantity of adust Oyl, and a _Caput mortuum_; which appearing to be a Coal concluded it to consist of Salt and Earth: but the Quantity of it was so small that I forbore to Calcine it. The Water I us'd to nourish this Plant was not shifted nor renewed; and I chose Spring-water rather than Rain-water, because the latter is more discernably a kinde of [Greek: panspermia], which, though it be granted to be freed from grosser Mixtures, seems yet to Contain in it, besides the Steams of several Bodies wandering in the Air, which may be suppos'd to impregnate it, a certain Spirituous Substance, which may be Extracted out of it, and is by some mistaken for the Spirit of the World Corporify'd, upon what Grounds, and with what Probability, I may elsewhere perchance, but must not now, Discourse to you.
