    were burst, and the whole cell appears as if filled with life, for every minute rapidly agitated atoms are seen every where; they are much smaller than even the minute particles that compose the coloured masses, and being of the same colour, I conclude that they come out of them. I will now give the dimensions of some parts of the plant and blossom. The principal stalk of the globule, fig. 8, is the t|q part of an inch long ; the smaller end is the of an inch thick, and surrounded by fifty-four red vesicles, which, deducting the spaces between them, leaves them about the Tjivo an kich thick. The segment-stalks, figs. 5 and 6, are the of an inch long, and ^ of an inch thick. The long vessels, figs. 7, 9, 10, and 11, are T-gV of an inch thick, the spirals within them o °f an inch, and the long vibrating fibres r r, near the ^ oV,o oo part of an inch thick. The seed without its tubes is about the -g-g of an inch long, and ~ of an inch thick. In fig. 1, I have mentioned a mass that was seen revolv¬ ing at top of one of the spiral tubes. Fig. 13 is part of a cell at the upper end of an arm, bearing fruit at the lower joints; but this cell having no surrounding tubes, had no fruit, and therefore grows much longer and thicker in this cell; and in several other similar ones in the same vial were many very lively revolving clusters, as shewn with arrows around them. These were larger and better defined than the cluster in the top of one of the spiral tubes in fig. 1. They were not in the central fluid, but in the circulating fluid, and therefore appeared to slide up and down close to the side; s s are the marks parting the two currents; the clusters here shewn rising came down in profile, as at t t; those that went up near to the right side came down at the middle of the back, and when they had slid over the top, their inner side was
