226 ON WATER AND WATERING PLANTS. 



taken out, two hundred and forty four grains : water expended 

 ten thousand seven hundred and thirty one grains. Though this 

 plant had the misfortune to he annoyed with very small insects, 

 that happened to fix upon it, yet had shot very considerable col- 

 lateral branches, and at least as many roots as either 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 preceeding. 



" L was set in Hyde Park conduit water, with the same quan- 

 tity of garden mould as in the former. The mint weighed, when 

 put in, ninety two grains; when taken out, three hundred and 

 seventy six grains. And the water which was expended, was 

 fourteen thousand nine hundred and fifty grains. 



" This pkmt was more flourishing than any of the preceedent, 

 had several considerable collateral branches, and very numerous 

 roots, to which terrestrial matter adhered very copiously. 



" The earth in both these glasses was very sensibly and con- 

 siderably wasted, and less than when first put in. The same- 

 sort of green substance here as in those above." 



" The plant M was set in Hyde Park water, distilled off with 

 a gentle still. It weighed when put in, one hundred and four- 

 teen grains ; when taken out, one hundred fifty five : the 

 water expended was three thousand eight hundred and three 

 grains. 



" This plant was pretty kindly, had two small collateral bran- 

 ches, and several roots, though not so many as that in H or I j 

 but as much terrestrial matter adhering to them, as those had. 

 The water was pretty thick, having very numerous, small ter- 

 restrial particles swimming in it, and some sediment at the bot- 

 tom of the glass. This glass had none of the green matter above 

 mentioned in it. 



"N was set in the residue of the water, which remained in the 

 still after that in M was distilled off. It was very turbid, and as 

 high coloured (reddish) as ordinary beer. The mint weighed, 

 when put in, eighty one grains ; when taken out, one hundred 

 seventy five grains. The water expended was four thousand 

 three hundred forty four grains. 



" This plant was very lively, and had sent out six collateral 

 branches, and several roots. 



" The glass O, had Hyde Park conduit water, in which was a 

 dram of dissolved nitre,
