consisting u boat six feet in diameter
followed out Of log The tree from
which the boat was formed must have
been twenty feet in circumference. The
wood, which is very hard, assumed blue

bullooks could not draw it.
A simple and effective method OF
bleaching bones, to give them the appear.
ance Of ivory has been discovered. After
digesting the bones with ether or benzine
to recover the fat, they are thoroughly
dried and immersed IN solution OF phos.
photic acid in water, containing one per
cent of phosphoric anhydride. In few
hours they are removed from the solution.
washed in water and dried. III
With one part Of alkaline sulpholeate
and one or two parts Of benznl, oil Of tur-
pentine, ETC., A. Muller Jacobs says we
obtain perfectly clear liquids Of an oily
constitution which, on the addition Of a
few drops of ammonia, dissolve in water
in any portion. With the aid Of heat.
sulphur, camphor thymol, naphthol phe-
mol, ETC.. may be dissolved in the sulpho.
leates in considerable proportion.
Ce!uvert is new material, formed by
passing paper, Or any fibrous form OF eel.
lulose, through bath Of nitric acid. The
glutinous surface SO produced are then
pressed together and washed, when they
form an extremely tough and hard sub.
stance, which is well adapted for use in
the industrial arts. 1t is proposed to
construct di hes for use in photography
out Of celluvert, but it will ALEC answer
well for dark slides.
Herr A. Jarolimek publishes some
novel statements on the temperature Of
steel in Dingier's Polytechnic. Hitherto
it has generally been considered that to
obtain specific degree Of softness it is
necessary to heat the hard steel to partic.

definite temperature-and then to cool it
rapidly. Herr Jarolimek says the re.

mentarily raising the temperature to a
particular degree can also be acquired by
subjecting the steel for longer time to a
much lower temperature.

A new drug found by DR.. auckland Is
creating much comment in the medical
world. 1t is called ayenesca, and is pro.
duced from Scotch oats. For nearly half
century chemists have been attempting
to extract and isolate this peculiar alko.

achieved a reputation as a neurologist
and insanity expert in New England, be.

that its curative actions are remarkable
in brain and nerve disorders; and its use
