But whether plants which float upon the surface of the water, be for the most part of cooling qualities, those which shoot above it of heating vertues, and why? whether _Sargasso_ for many miles floating upon the Western Ocean, or Sea-lettuce, and Phasganium at the bottome of our Seas, make good the like qualities? Why Fenny waters afford the hottest and sweetest plants, as Calamus, Cyperus, and Crowfoot, and mudd cast out of ditches most naturally produceth Arsmart? Why plants so greedy of water so little regard oyl? Why since many seeds contain much oyl within them, they endure it not well without, either in their growth or production? Why since Seeds shoot commonly under ground, and out of the aire, those which are let fall in shallow glasses, upon the surface of the water, will sooner sprout then those at the bottom? And if the water be covered with oyle, those at the bottome will hardly sprout at all, we have not room to conjecture. Whether Ivy would not lesse offend the Trees in this clean ordination, and well kept paths, might perhaps deserve the question. But this were a quæry only unto some habitations, and little concerning _Cyrus_ or the Babylonian territory; wherein by no industry _Harpalus_ could make Ivy grow: And _Alexander_ hardly found it about those parts to imitate the pomp of _Bacchus_. And though in these Northern Regions we are too much acquainted with one Ivy, we know too little of another, whereby we apprehend not the expressions of Antiquity, the Splenetick[164] medicine of _Galen_, and the Emphasis of the Poet, in the beauty of the white Ivy.[165] [164] Galen. de med. secundum loc. [165] Hedera formosior alba. The like concerning the growth of Misseltoe, which dependeth not only of the _species_, or kinde of Tree, but much also of the Soil. And therefore common in some places, not readily found in others, frequent in _France_, not so common in _Spain_, and scarce at all in the Territory of _Ferrara_: Nor easily to be found where it is most required upon Oakes, lesse on trees continually verdant. Although in some places the Olive escapeth it not, requiting its detriment, in the delightful view of its red Berries; as _Clusius_ observed in _Spain_, and _Bellonius_ about _Hierusalem_. But this Parasitical plant suffers nothing to grow upon it, by any way of art; nor could we ever make it grow where nature had not planted it; as we have in vain attempted by inocculation and incision, upon its native or forreign stock, and though there seem nothing improbable in the seed, it hath not succeeded by sation in any manner of ground, wherein we had no reason to despair since we reade of vegetable horns [SN: Linschoten.], and how Rams horns will root about _Goa_.
