Again, if the tube be taken out of the fluid when it is risen to its full height, there will be a small bubble of the fluid hang at the end of the tube; which is of the very same consequence as if the tube just touched the surface of the fluid; and the reason of its hanging there is by the circumambient mediums pressing equally on all sides, except on that taken off by the end of the tube; so by hydrostatics or universal laws of nature, the stronger parts of the fluid will press toward the weaker until the equilibrium is restored against the end of the Tuble. It is conjectured that the Ratio of the heights to which [[strikethrough]] any [[/strikethrough]] fluids will ascend in the same capillary tube, will be nearly as the specific gravities of the fluids reciprocally, but yet mercury will rather sink than rise. it is likewise thought, and has been tried with success in several fluids, and with different substances, that by immerging any solid specifically [[underlined]] heavier [[/underlined]] than the fluid, it will rise with a convexity about the body at the surface, and by a narrow examination it will appear to stand close round the body concave towards the bottom: but if a body specifically [[underlined]] lighter [[/underlined]] than the fluid, be immerged, it will be concave about the body at top of the surface and convex towards the bottom just under the surface: the cause of which remains a secret with me at present.

    Hence I am led to presume there is a complication of three different effects of Fluids rising in capillary tubes. [[viz]] 1.st that of Friction; 2nd the pressure or action of some medium or fluid at top of the tube, since it does not rise so high in a short one as ^ [[insertion]] in [[/insertion]] a longer, tho' both are of the same bore; this cannot be the Air, because we found the very same effects in an exhausted Receiver.  See likewise S.[i]r I. Newton's Optics p.367. [[Quære]] Ult. but it might be worth while to try the same experiment again in vacuo, tho' it has appeared to succeed equally ^ [[insertion]] the same [[/insertion]] therein as in open Air.  3.rd Whether the Fluid be specifically lighter or heavier than the tube, because of fluids standing concave or convex at the surface about an immersed body according [[strikethrough]] ly [[/strikethrough]] as that body is specifically lighter or heavier than the fluid.  And likewise that mercury will sink with a capillary tube of Glass.
    W.J. took the section of a capillary tube and of the plant called the Sun spurge, upon examining them we discovered the tubes about the center of the plant to be much larger than that of the capillary tube and likewise the specific gravity of the juice in the plant heavier than water, yet the juice rose upwards of 2 Feet 1/2 in the plant, whereas water would not rise in [[strikethrough]] a [[/strikethrough]] ^ [[insertion]] the [[/insertion]] tube of Glass (of less bore) to the height of 2 Inches.  Moreover, the sap in vegetables only rises at a stated season of the year and at stated hours of the sun's appearance: From which two cases it is evident, the rising of liquor in capillary glass Tubes is not similar with vegetation and therefore cannot be accounted for thereby.
Light is the only [[underlined]] natural [[/underlined]] Fluid in the Universe and all others are accidentally produced by it, because it will give fluidity to solid masses and take it away from fluids, as Gold, Silver, [[&c.]] by infusing a sufficient
