The water in thefc two glaffes that had no plants in 
them,, at the end of the experiment exhibited a larger 
quantity of terreftrial matter, than that in any of thofe 
that had the plants in them did. 
I he fediment in the bottom of the phials was great- 
er, and the nubecuke diffufed through the body of 
the water 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 Idem of the plants 
that was within the water, wherein they rotted and 
dilTolved. 
The terreftrial matter in the rain water was finer than 
that of the fpring water. 
Experiments , Anno 165(2. 
The glaffes 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 mold kind- 
ly, frefh, fprightly ftioots he could chufe. The wa- 
ter and plants were weighed, as above, and the phials 
fet in a line in a fouth window, where they ftood 
from June the 2d to July the 28th, which was juft 
56 days. 
1 he plant H was all along a very kindly one, and 
ran up about two feet in height. It hadftiot 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 leffer roots 
came out of the larger on two oppofite fides for the 
mold part, fo that each root, with its fibrilke, appears 
not unlike a fmall feather ; to thefe fibrilke adhered

pretty much terreftrial matter. In the water, which 
was at laid thick and turbid, was a green fubftance, 
refembling a fine thin conferva. 
1 he plant I was as kindly as the former, but had fiiot 
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 infedts that happened to fix up- 
on it, yet had Ihot very confiderable collateral 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 flourifhing than any of the 
preceding, had feveral confiderable collateral branches, 
and very numerous roots, to which terreftrial matter 
adhered very copioufly. 
The earth in both thefe glafles 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 feveral 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.

The glafs O had alfo Hyde-Park conduit water, in 
which was diffolved a drachm of nitre. The Mint

died in a few days, as' likewife did two more fprigs

diffolved an ounce of good garden mould, and a 
drachm of nitre, and in a third, half an ounce of 
wood a flies, and a drachm of nitre, but the plants in 
thefe fucceeded no better than the former. In other 
glaffes he diffolved feveral other forts of earth, clay, 
marles, and variety of manures, 8cc. and he fet Mint
