"Scientific American Supplement, No. 794, March 21, 1891"

It will, therefore, be
seen that a carpet made according to Fig. 1 will show five
colors--three colors produced by the weft and two colors produced by
the ingrain warp. Fig. 2 represents a carpet made with two-ply, in
which case only four colors will be produced, two by the weft and two
by the ingrain warp. It is, consequently, obvious that a carpet made
in the manner above described will have a corresponding pattern or
figure on both its sides, allowing it to be used on both sides. Fig. 3
also shows a two-ply carpet, but, in this case, six colors are
produced, i.e., two colors by the weft and four by the ingrain warp,
marked d, d?, e, and e?, the warp being so manipulated by the harness
as to make the carpet reversible, and having a corresponding pattern
or figure on both sides.--_Journal of Fabrics._

ARAEO-PICNOMETER.

A modified araeometer has been recently patented by Aug. Eichhorn, in
Dresden, Germany (Deutsches Reichs-Patent, No. 49,683), which will
prove a great boon to chemists, distillers, physicians, etc.
