In the Memoirs of the French Academy of Sciences,
M. Varignon gives us a Treatife on the Proportions neceffary
for the Diameters of 7hbes, to give precifely any determinate
Quantities of Water. -- The Refult of his Piece turns upon
thefe two Analogies; That the Diminutions of the Velocity
of Water, occafion'd by its Fri&ion againfi the Sides of the
7'ubes, are as the Diameters; the libes being fuppofed
equally long; and the Quantities of Water i~hing out at
the 1iibes, are as the Iquare Roots of their Diameters, de-
dufting out of them the Quantity each is diminiflh'd. See

TUBE, in Aflronomy, is fometitnes ufed for t'elefcope;

The Goodnefs of the Tribe, being of great Importance to
that of the Telefcope; we fhall here add its Struaure.
Conufruation of a DraqW-TUBE for a Telefcope.
The great Points to be regarded here, are, that the 7Vibe
benIt troubhlonme by its Weight, nor lyable to warp and
difturb the Pofition of the Glafres: So that any kind of
Zube will not ferve in every Cafe: But
lo If the Aube be fimall, 'ris bell made of thin brafs
Plates cover'd with Tin, and form'd into Pipes or Draws, to
fide within one another.
20 For long 7Tubes, Iron would be too heavy i for which
reafon fome chufe to make them of Paper, thus: ---- A
wooden Cylinder is turn'd, of the Length of the Paper to
be ufed; and of a Diameter equal to that of the linalleft
Draw. About this Cylinder is roll'd Paper, till it be of a
fufficient Thicknefs: When one Pipe is dry, provide others
after the fame manner; fill making the laft ferve as a Mould
for the next, till you have enough for the length of the Tube
defired. Lafily, to the Extremes of the Draws are to be
glew'd wooden Ferrils, that they may be drawn forth the
better.
30 Since Paper Draws are apt to fwell with moitl Weather,
fo as to fpoil their fliding; and in dry Weather to fhrink,
which renders them loofe and tottering ; in both which
Cafes, the Situation of the Lens's is eafily diilurb'd; the
befl Method of making lubes, is as follows: Glue Parch-
ment round a wooden Cylinder; and let the Parchment be
volour'd Black, to prevent the refleaed Rays making any
Confurion. Provide very thin Slits of Beech, and bending
them into a Cylinder, glue them carefully to the Parchment:
Cover this wooden Cafe with white Parchment; and about
its outer Extreme make a little Ring or Ferril: after the
fame manner make another Draw over the former; and then
another, till you have enough for the Length of the 7'ube.
To the inner Extremes of each Draw, fit a wooden Ferril,
that the fpurious Rays Striking againit the Sides, may be in-
tercepted and loft. In thofe Places where the Lens's are to
be put, it will be proper to furnifh the Ferrils with Female
Screws. Provide a wooden Cover to defend the Objea
i Glafs from the Duff, and putting the Eye Glafs in its
woodn Ferril, falen it by the Screw  to the Tube. Laftly,
provide a little wooden 9tube of a Length equal to the
Niflance the Eye Glafs is to be from the Eye, and fit it to
the other Extream of the Tuvbe.
