The rate OF progression of a storm
is often fifty miles an hour. and a series

Pieces of natural iron have been
found in Arizona, near the Canon
Diabio, which possess an extraordinary
hardness, and contain small cavities
which are filed with black substance
| in which are diamonds, some half q
millimetre in diameter. The specimens
of natural iron appear to be Of meteoric
origin. The occurrence of the diamond
| in natural iron, whether of meteoric
origin or not, is an extremely inter est

The American Cotton and Wool
Reporter has begun an interesting eX-
pertinent in Maine, it being an attempt
to make mutton sheep husbandry profit
able on abandoned farms. Six deserted
homesteads, comprising about 420 acres
of fairly good land, have been pur-
chased and will be heavily stocked with
native ewes and thoroughbred IIamp-
shire rams. The farm will be con-
Quoted by scientific breeder and agri-
culturist, who will make reports from
time to time of the progress of the
undertaking, and the result will be
awaited with interest by down-east
farmers.
-Coppeeplating sheet zinc for build
ing purposes has been tried with con-
siderable success in Germany, the zinc
combining well with the copper. The
zinc is cleaned with soda and purified
by a weak acid bath. In twenty
parts of water one part of refined ver-
digris and twelve parts of cream of tar
tar are dissolved, and the mixture is
| to 1a ho;
to four parts of Spanish white are
added. The latter is decomposed and
precipitated as lime tartrate. The
darl1-blue liquid, after filtering, can be
used rs bath for the sheet zinc or for
the production of copperplating paste.
DIR. Lauder Brunton, in the course
of recent letter on 'Mastication," at
St Bartholomew's hospital, made use
of the following remarks: 81 think it
was magnificent stroke of genius on
the part of the president of the Royal
College of Physicians, Sir Andrew
Clark, when he informed Mr.. Gladstone
that he had one mouth and thirty-two
teeth, and that for every mouthful of
food he took every tooth should have a
chance, SO that he should take thirty
| y
continued Dr. Brunton, ''if the patient
has lost some of his teeth he should
allow two bites for every missing tooth,
; and even that will not always do if
many teeth have gone"
The California Academy of Sciences
has become the possessor sf an unusu-
ally sound skeleton of rhachianeetes
glaucus, or California gray whale. 1t
is forty-fve feet in length, and has
twenty-siX ribs, seven feet on the curve,
and two great scapulB, resembling
broadaXes. The jaws are nine feet in
length. The California gray whale has
no teeth, but is provided with baleen,
or "whalebone," row of bony sub.
stances resembling brushes, These sift
the water and catch the animalculH
floating in it, the only food of this class
OF whales es-Indianapolis News.
The resources OF the lecture-room
are decidedly increased when Prof.
Dewar was able, in lecture on chem,
istry in London lately, to produce
liquid oxygen in the presence of the
audience literally by pints, and to pass
; liquid air about the room in claret
: glasses. Oxygen liquifies at about 25C
degrees below zero, and air ut 3t3 de-
grees below zero. If the earth were
D reduced to a temperature $50 degrees
below zero it would be covered with a
sea of liquid air thirty-five feet deep
r Prof. Dewar's process of liquefying
oxygen and nitrogen was with a hun
5 dred pounds of liquid ethylene and fifty
pounds of nitrous oxide, with the aid O.
