SCIENCE, INDUSTRY, And INVENTION.

Mr. f. Anthony of this city has Just published
some 20 or 80 stereoscopic views Of Californian
scenery including the renowned falls, the big trees,
and most of the wonders of the Golden State. The
mountain scenery presents some Of the deepest preci
pices known. The Yosemite Valley and Falls are
illustrated by several views. One Of the views shows
man standing at the foot Of Of the big trees; il
does not look as though he could cut it down in life
time. Two or three scenes in a kanyOn give vivid
idea of the darkness and rocks and tumbling water
which make this new word necessary to name them.
There are charming views along the MERGED River,
complete panoramic views Of San Francisco, some
views of Sacramento, and not least in interest," the
scene of Brodericks murder.
New MErAL-von Kobell, the distinguished Pro-
fessor of Mineraoey at the University of Munich, has
discovered the acid of a metal in the somewhat
rare mineral from Tammela, in Finland, hitherto
known as Tantalite Won Kobell, following usage,
has chstened his substance after an ancient d.
vinity and being himself addicted to the nobest Of
Alpine sports has carried the of the chaste
hunress" into chemistry. Danic acid is the name Of
the acid, and Danium must be the designation Of it's
metallic base.
IYFLUEScE OF MAGNETISM on THE HARDNESS OF
IRoS.-Ruhmkorf has observed that when one OF the
poles of a steel magnet is camped within soft iron
srIup the latter becomes much harder and more diff
cult ole BY removing the magnet the iron RECEIVERS
its original softness.
ARSENIC IN AGRIcULTURAL PLASTs.-Dr. +. w.
Davy has detected arsenic in peas cabbages and Swe-
dish turnips, which had been MANFRED with super
phosphate of lime. This fertilizer very extensively
manufactured in England especially for use on the
turnip crop, from various phosphate minerals, and
from bones by the help of arsenical oil OF yrio The
arsenc, being thus proved to enter vegetation, may
very easily and naturally pass into animals and be re-
tanned in their organism. This is another striking,
pIesumptve proof of the worhessness of thattoxoog-
ical evidence which hangs man on the strength Of
minute of arsenic being found in working up sew
eral pounds of flesh and yiscera.
ARTIFICIAL WooD.-It is said in the Deptschs
GeuerbeZeitung that saw-dust can be made over into
wood by mingliDg it intimately with one-eighth its
weight Of powdered rosn, and pressing the mixture,
cheeelke between hot iron plates nclosed by frame,
corresponding in size TO the dimensions of the required
board. 1t is easy to give the artificial wood any re-
qured color, to marble grain it, desired. 1t may
he nodded wrought TO any pattern. We believe
that while such saw dust boards may be valuable To-
ornamental purposes; they cannot be of much use
where strength is required.
TIE PATENTWooD OR FIBRoUs-SLAB COMPANY Of
London, working under Bieefeld patent, showed at
the great exhibition beautiful samples Of another man
ufacture, composed according to Kletzinsky of hemp
and flax waste scate of potash soluble glass, clay
80 per cent little aspbaltum and copperas beside
coorng matters This sort of miReraii-ed paper
aach6 ard serves for veneering ornamental panel
ing as well as for architectural holdings, reefs &C.,
and has been used for chandeliers. bust of Flax
man, executed in this material was much admired at
the London exhibition.
PHoToGRAPHING THE ISyIsIBLE-Dr Gladstone Of
London has made the remarkable discovery that char
acers traced on white paper with the solution of a
fuOreseea body, which on drying are undiscoverable
by the eye, may be brought out a collodiumsiver
surface in the same way in which positives are OBJ
tanned from negative photograph.
Fluorescent bodies, as, for example, sulphate OF
qunine infusion of the bark of horsechesnut or tea,
al fuorspur thence the name, have the property OF
preventing greatly checking the transmission of the
actricc chemical rays that the characters writ
ten with such iuoreseent body are left white on
dark ground, when copied as described.
