ropgBaIK sUG ENCE NOTES,

rO0u was constructed III one nuuuTeu uhgsJ
under Sir h. Temple,in the late Afgan cam
paign, and is pronounced to be one of the
greatest leats in the way of rapid railway
making on record.
"A debate recently took place on the
origin of the blonde race of mankind, at a
session of the Authropological Society of
Paris. The original seat was placed in the
region of Turkestan by some of the speakers
while others maintained that they origin
ated in Europe.
The jealousy existing in the hearts OF
Europeans towards American inventors is
plainly manifest in this little sarcasm re-
Gently perpetrated by the London Punch:
"a Yankee baby will crawl out of his cradle,
take Il survey of it, invent an improvement
and Apply for patent before he is six
months old"
1t is estimated that not one out Of every
ten of uneducated men ever achieve success,
and that the educated man will, on an av-
erasc. be farther advanced in his career at
thirty-five years of age than the uneducated
at forty-fve or even ffty-thus all should
receive sound and liberal education,if they
would succeed.
-"Beware of them" says a scientist, "Gor
salves make and keep the skin sore, plasters
prevent wounds from healing, eye waters do
often more injury than goood, most hair
dyes produce sore eyes, beautifying washes
are often poisonous, ditto toilet powders,
while scented soaps are usually too sharp by
the free alkali the contain"
--Tyre-setting and distributing by ma
chnery, the result of an investigation and
series of experimenting running over many
years, has been successfully accomplished
by Henry A. Burr, of New York City. The
matter for the Practical american of that
city, was recently set by one Of these ma
chimes, and in about one fourth the time it
would have taken the same number Of per-
sons to set the type by hand.
AS an insectcde, the juice of the toma-
to plant is said to be of great value. The
leaves and stems are well boiled in water,
and when the liquid is cold it is sprinkled
over plants attacked by insects, when it at
once destroys caterpillers, black and green
| hys, gnats and other enemies to vegetables,
and in no way impairs the growth of the
plants. A peculiar odor remains and pre-
time.
The substitution of Dynamo machines
in place of galvanic cells for generating the
electric current, is a new departure IN teleg-
raphy. These machines were invented by
Stephen D. Field, of San Francisco, Calilor-
mia, and so complete a revolution in the
economies of telcgraphy is being made by
them wherever adopted, that it is thought
but few mouths will elapse ere they will
be in general use throughout the world.
The King of Belgium has offered re-
ward of 5000 for the best treatise on meaLs
of improving harbors on low and sandy
coasts. Essays for competition, which is
open to the world, must be submitted to the
Ministry of the Interior at Brussels, before
January |, 1881.
The "Dentaphone," called by some the
"Audiphone," an invention of recent origin
by means of which deaf mutes are enabled
to hear through the teeth is being greatly
improved upon of late and there is no dOub
but that the instrument will work a revolu
ton in the ways of educating the deaf and
dumb. The mOuthpiece of the instrument
is held between the teeth, and in this way
human speech can be conveyed TO any dea
person whose auditory nerve has not beer
literally destroyed.
An Engishman has invented what he
calls "luminous paint" which he claims
will throw oil a bright light in dark plaoe
and at night. thus rendering houses anC
other obj acts selfluminous. A piOnec
company has been formed in London for il
manufacture, and it is said that there is nov
an eager demand for the mysterious illumi
nant. We shall await its introduction il
) this country with considerable anxiety.
The bill recently introduced before con
gress by Senator Hill, of California, provid
) ing for an appropriation of $4,000 to b
} used in sinking artesian wells in the ART
5 regions of the Rocky Mountains, has bee
reported upon iavorably, by the commtte
ON public lands. 1t is estimated that ther
are now some FIVE hundred million acres
D government lands, in those regions, at pres
ent unsalable, because Of their aIidity, ,whic
could be converted into valuable iarmIn
lands by this means.
During the past few months some i'm
portant discoveries of gold and silver hav
been made in the State of Maine. TIL
Riverside Mining Company, with capitG
of 100000, has been organized at Camdel
5 Knox county, and men are employed nigi
and day. Several other wealthy cumpanI,
' have also been formed, and all are doing
profitable business. An assay of ore recen
T ly taken from the Deer Isle mine, on De,
| Island, Penobscot Bay, resulted as follows
Gold, $780, silver, $780, copper, SlOj lead

Prof John Trowbridge once wisely II
marked that it would certainly be a grea
boon to the world il the general leyel {
, scientific education could be raised, so thi
each young man or young woman, when !
or she issues from school doors, should haN
enough definite knowledge of the great Law
Of the physical universe to instantly d,
j nounce blue glass theories and attempts
a perpetual motion, not from the pride
~ knowledge, but from the feeling that erro
4 credullty aud superstition should be con
buted with truth.
p One of the many processes for maxim
= Photographic and heliotypic printing plat,
1 isas follows: Take ofpure white glue kilC
. gramme, soak in clear white water some
: hours, then melt in the usual way until a
the water has been cooked out, adding
l. grImmes potassium bChromate. Get
e suitable glass, provide it with rim Of putt
5. To prevent the solution from running q.
: coat the glass with OK gall, then pour O
l. your solution and allow it to remain tvs
a days in dark place, when the glue tabl,
e may be detached and is ready for use. Pr,
# pare Il smooth block of wood or metal III
It size of the plate you want made and glu
e, the tablet to its place. Now place tran
a parent negative drawn in bold lines, an
Ie strong contrast of lights and shades, oy,
d the smooth surface Of the tablet, aud expo
rs To the sunlight for from one TO three hour
l. After this procedure moisten the face wit
r water, aud finally remove by means OF
v, soit, moist cloth, all glue not hardened VI
le der the influence of light, when the eliel
,e will show the drawing in perfect relief wit
,e smooth printing surface. If desired. ele
err trotypes may be easily taken from the
ID plates. We shall give other processes #
