quantity of terreftrial matter, than that in any of thofe 

 that had the plants in them did. 

 The fediment in the bottom of the phials was great- 

 er, and the nubeculae difFufed through the body of 

 the wkter thicker, and of that which was in the 

 others, fome of it proceeded from certain fmall leaves 

 that had fallen from that part of the ftem of the plants 

 that was within the water, wherein they rotted and 



diflblved. 



The terreftrial matter in the rain water was finer than 



that of the fpring water* 



Experiment iy Anno 1692. 



The glafTes made ufe of in this were of the fame fort 

 with thofe of the former experiment, and covered over 

 with parchment after the fame manner. 

 The plants here were all Spear Mint, the moft kind- 

 ly, frefti, (prightly fhoots he could chufe. The wa- 

 ter and plants were weighed, as above, and the phials 

 iet in a line in a fouth window, where they ftood 

 from June the 2d to July the 28th, which was juft 

 ^6 days. 



The plant H was all along a very kindly one, and 

 ran up about two feet in height. It had fhot but one 

 confiderable collateral branch, but had fent forth ma- 

 ny and long roots, from which fprung very numerous, 

 though fmall and fhort leffer fibres. The lefler roots 

 cameout of the larger on two oppofite fides for the 

 moft part, fo that each root, with its fibrillar, appears 

 not unlike a fmall feather ; to thefe fibrillas adhered 



refcmbling a fine thin conferva. 

 The plant I was as kindly as the former, but had (hot 

 no collateral branches. Its roots, the waters, and the 

 green fubftance, all much as in the former. 

 The plant K, though it had the misfortune to be an- 

 noyed with very fmall infefts that happened to fix up- 

 on it, yet had (hot very confiderablecoUateral branches^ 

 and at leaft as many roots as either H or I, which 

 had a much greater quantity of terreftrial matter ad- 

 hering to the extremities of them. The fame green 

 fubftance here that was in the two preceding. 

 The plant L was far more flouriftiing than any of the 

 preceding, had feveral confiderable collateral branches, 

 and very numerous roots, to which terreftrial matter 

 adhered very copioufiy. 



The earth in both thefe glaftes were very fenfibly and 

 confiderably wafted, and lefs than when at firft put 



in. The fame fort of green fubftance here as in thofe 

 above. 



The plant M was pretty kindly, had two fmall col- 

 lateral branches, and feveriil fhoots, tho* not fo many 

 as thofe in H or I, but as much terreftrial matter ad- 

 hering to them as thofe had. The water was pretty 

 thick, having very numerous fmall terreftrial particles 

 fwimming in it, and fome fediment at the bottom of 

 the glafs. This glafs had none of the green matter 

 above-mentioned in it. 



The plant N was very lively, and had fent out fix 

 collateral branches, and many roots, but the water was 

 very turbid, and as high coloured as ordinary beer.
