THINGS New AND INTERESTING IN sc1ENoE.-Pro
lessor Hansen, of Seeberg, renowned astronomer,
has recently completed series Of elaborate cacula
TONS based observations of the moon which clear
away some of the difficulties of the question re-
CARDS our satellite His published results are for the
most part abstruse and technical-appreciable only
by astronomers but among them occur certain mat
tiers of popular interest He finds for example, that
the moons center OF gravity is about 40 miles from
the center of its mass, difference sufficiently great
to make an effect. Hence, ne argues, we ought to
consider the two hemispheres of the moon, of which
one is visible and the other is invisible for us, es
sentiay different with regard to their levels their
climates, and all that depends thereon. Seeing that
the lines of level regulate themselves principally with
reference to the center Of gravity the hemspheres of
moon turned towards us rises much more beyond the
mean level than the opposite hemisphere and al
though the former presents itself to US as sterile re-
gion, void Of atmosphere and animal life, we cannot
conclude that it is the with respect to the latter
The mean should prevail round the edge as seen by
us; and in truth we cannot say but that traces
of atmosphere do show themselves.
A new method has been discovered of investing or
binary paper with many of the useful properties of
parchment The effect is attained by merely drawing
piece of common unsized paper through mixture
of two parts of concentrated suphuric acid with one
part OF water, and then Immediately and thoroughly
washing it in water. II the acid either exceeds or
falls below the above named strength then the quality
OF the parchment paper is deteriorated. Paper thus
prepared is strong that ring of it, seveneghth of
IN inch in width will sustain from 50 to 100 pounds
This paper from its strength and durability, suit
able for legal Deeds policies OF insurance, etc. Hay-
ing the appearance Of yeum it is likely to supercede
the use of that article in bookbinding it will receive
oil colors, and will answer perfectly for maps and ell
cravings.
A species of concrete, in which ashes are prnci-
pal ingredient has of late been adyantageously intro
duced for building purposes in Paris. One manutac-
turing firm is reported to utilise most OF their waste in
the working up of this new material. So rapidly has
this artificial stone been improved, that slabs for
floors are now made seven metres long by Sin metres
wide which, being laid all in one place. no beams or
vautng are necessary underneath. The inventor
says" fabricate in betOnS dggomeTeS, as had as
the best stone all the parts of house, cellars drains
paving flags, sinks walls, floors, rootS exterior orna-
mentS, without using wood or brick. BY this process
the house, however large it may be, is a menoith-
and this menoth equals, at least in sodity, masonry
of hewn stone and costs much less than the coarses1
