 Rh liquor, both from that I had cut, and that I had cut it from, without pressure.

Which made me think, that the motion of this Plant upon touching, might be from this, that there being a constant intercourse betwixt every part of this Plant and its root, either by a circulation of this liquor, or a constant pressing of the subtiler parts of it to every extremity of the Plant. Upon every pressure, from whatsoever it proceeds, greater then that which keeps it up, the subtile parts of this liquor are thrust downwards, towards its articulations of the leaves, where, not having room presently to get into the sprig, the little round pedunculus, from whence the Spine and those oblique Fibres I mentioned rise, being dilated, the Spine and Fibres (being continued from it) must be contracted and shortned, and so draw the leaf upwards to joyn with its fellow in the same condition with it self, where, being closed, they are held together by the implications of the little whitish hair, as well as by the still retreating liquor, which distending the Fibres that are continued lower to the branch and root, shorten them above; and when the liquor is so much forced from the Sprout, whose Fibres are yet tender, and not able to support themselves, but by that tensness which the liquor filling their interstices gives them, the Sprout hangs and flags.

But, perhaps, he that had the ability and leisure to give you the exact Anatomy of this pretty Plant, to shew you its Fibres, and visible Canales, through which this fine liquor circulateth, or is moved, and had the faculty of better and more copiously expressing his Observations and conceptions, such a one would easily from the motion of this liquor, solve all the Phænomena, and would not fear to affirm, that it is no obscure sensation this Plant hath. But I have said too much, I humbly submit, and am ready to stand corrected.

I have not yet made so full and satisfactory Observations as I desire on this Plant, which seems to be a Subject that will afford abundance of Rh
