(H.) _Hyde-Park Conduit Water_, alone. The _Mint_ weighed, when put in, 127 Gr. when taken out, 255 Gr. The whole Quantity of Water expended upon this Plant, amounted to 14190 Gr. This was all along a very kindly Plant; and had run up to above two Foot in height. It had shot but one considerable collateral Branch; but had sent forth many and long Roots, from which sprung very numerous, though small and short, lesser Fibres. These lesser Roots came out of the larger on two opposite sides, for the most part; so that each Root, with its _Fibrillæ_, appear'd not unlike a small Feather. To these _Fibrillæ_ adher'd pretty must Terrestrial Matter. In the Water, which was at last thick and turbid, was a green Substance, resembling a fine thin _Conserva_. (I.) The _same Water_, alone. The _Mint_ weigh'd, when put in, 110 Gr. when taken out, 249. Water expended, 13140 Gr. This Plant was as kindly as the former, but had shot no collateral Branches. Its Roots, the Water, and the green Substance, all much as in the former. (K.) _Hyde-Park Conduit-water_, in which was dissolved an Ounce and half of _Common Garden-earth_. The _Mint_ weigh'd, when put in, 76 Gr. when taken out, 244 Gr. Water expended, Gr. 10731. This Plant, though it had the Misfortune to be annoy'd with many small Insects that hapn'd to fix upon it; yet had shot very considerable collateral Branches; and at least as many Roots as either that in H or I; which had a much greater Quantity of Terrestrial Matter adhering to the Extremities of them. The same green Substance here, that was in the two preceding. (L.) _Hyde-Park Water_, with the same Quantity of _Garden-mould_ as in the former. The _Mint_ weigh'd, when put in, 92 Gr. when taken out, 376 Gr. The Water expended 14950 Gr. This Plant was far more flourishing than any of the precedent; had several very considerable collateral Branches, and very numerous Roots, to which Terrestrial Matter adhered very copiously. The Earth in both these Glasses was very sensibly and considerably wasted, and less than when first put in. The same sort of green Substance here as in those above. (M.) _Hyde-Park Water_, distilled off with a gentle Still. The _Mint_ weigh'd, when put in, 114 Gr. when taken out 155. The Water expended, 8803 Gr. This Plant was pretty kindly; had two small collateral Branches, and several Roots, though not so many as that in H or I, but as much Terrestrial Matter adhering to them as those had. The Water was pretty thick; having very numerous small Terrestrial Particles swimming in it, and some Sediment at the bottom of the Glass. This Glass had none of the green Matter above mentioned, in it.
