224 ON WATER AND WATERING PLANTS. 



" D, The common solatium or nightshade set in spring water. 

 The plant weighed when put in, forty nine grains, and when 

 taken out one hundred and six grains, having gained in seventy 

 seven days-fifty seven grains. 



" The water expended during the seventy seven days was 

 three thousand seven hundred and eight grains, which was sixty 

 five three fifty seven as much as the augment of the plant. 



" The spearmint D had several buds upon it, when first set in 

 water ; these in some days became fair flowers, which were at 

 length succeeded with berries. 



" Several other plants were tried that did not thrive in water, 

 or succeed better than the cataputia. 



F, lathy ris or cataputia gerb, set in spring water ; it weighed 

 when set in, ninety eight grains, when taken out one hundred 

 and one grains and an half. The additional weight for the seven- 

 ty seven days being but three grains and an half. 



" The quantity of water, spent upon it during that time, was 

 two thousand five hundred and one grains, which is seven hun- 

 dred fourteen times four thirds as much as the plant was aug- 

 mented. 



" F, G, those two phials so marked, were filled, the former 

 with rain, and the latter with spring water, at the same time that 

 the other before mentioned were, and stood as long as they did, 

 but had neither of them any plant, his design in this being only to 

 inform himself, whether any water exhaled out of the glasses, 

 otherwise than through the bodies of the plants. The orifices of 

 these glasses were covered with parchment, each piece behig 

 perforated with a hole of the same bigness with the other. And 

 he suspended a bit of stick, about the thickness of the stem of 

 one of the aforesaid plants, but not reaching down to the surface 

 of the included water. These he put in thus, that the water in 

 these might not have more scope to evaporate, than that in the 

 other phials. 



" Thus they stood the whole seventy seven days in the same 

 window with the rest ; when, upon examination, he found none 

 of the water in these wasted or gone off. Though he observed, 

 both in these and the rest, especially after hot weather, small 

 drops of water adhering to the insides of the glasses ; that part 

 of them that was above the surface of the inclosed waters. 



" The water in these two glasses that had no plants in them, at 

 the end of the experiment, exhibited a larger quantity of terres-
