Oatmeal! and the Intellect.
At the annual meeting of tho American
Association for the Advancement of Eduention, recently held in this city, Professor
Haldeman advocated the uso of high phosphorized foed for teachers, they having
much expenditure of brain. He said
“the reason why the Scotch were so intellectually acuto and activo must be attribu
ted to the use of oatmeal in their youth.
Oats contuin more phosphorus than any
other vegetable.” He also recomended
ezys as oxcelleut foed for teachers, in ordor to increase their intellectual capacities. Lut the mental acuteness and general intellectual strength which characterize the people of the above-named country cannot be dne to the phosphorus of
their ontmeal, which is their common
breakfast food, for it so happeus that wheat
contains more of it than oats. The quantity of soluble phosphates in wheat, according to Professor Johnston—himself a
Scotchnian—is more than one per cent.
groater than in oats. In his work on Agricultural Chemistry, pages 503 and 510,
the composition of wheat aud oats is given
in tables.
Oatmeal is, nodonbt, very excellent food
for manand beast, and sois Indian cornmeal, but ueither of them will confer intellectun] acuteness upon any mau. Dnll
teachors or dull men cannot be made philesophors cither by the nse of eggsor oate.
We must look to eomo other cause than
oatmeal for the metaphysical mind of the
North Britons. That canse is, no doubt,
to be fonnd in their education. Common
schools havo beon in existence in that
country fortwo centurics, and the strict
family training of childrcu by catechisms
being similar to that which use to prevnil
in New England, and various other parts
of our country. The Welsh, the Norwegians and Trish uso oatmeal extensivo for
food.—Sci. Am.
Patent Lunacy.
The Railroad Guide, ina very sensible
article says: Thero is no more melancholy
sight than a man afflicted with this mania
—which iu many of its aspects closcly resembles tho passion for gambling—who is
poor and dependent upou his daily exerttous for tho support of himself and family. He has constantly beforo him the
vision of aflluence, and with it the pangs
of poverty. Experience teachos often in
ynin, and one failure only eeems to gild
the brighter the next vagary of invention.
We knowof men who for years have spent
all the time and money they could control
to develop nnd hring into use inventions
which it was quite easy to demonstrnte
would be practically useless. These same
men, if remonstrated with for thus following 2 constantly losing carecr, are always
ready to justify themselves by citing the
great inventors whose beginning were
equally discouraging and whoso ultimate
euccess was nevertheless most brilliant.
Alas! if those who reason thus would only
etudy, among other things, logic, eo that
they might see that because eome inventors were iu the beginning poor and had a
hard time generally, but eucceeded in the
end, it does not thorefore follow that alt
who exercise the inventive faculties in the
midst of penury will emerge ultimately
into enccess and aftluence,

Tor Mysrerms or A Hair Brusn.—A.
writer in the American Journal of Micro-.
scopy has been exploring the forests of
bristles in a hair brush eurreptitioualy .
purloined from a lady’s toilet staud, and
though it contained nothing which wo are
accustomed to regard with unqualified
horror, the results of his iuvestigations
prove that there are myeteries ordinarly
undreamed of in simple appliances of the
toilet. There are concealed in the damp
lint of hair brushes, unless kept olean by
the use of bicarbonato of potassa or carbonate of soda, mauy liviug things, too
small for detection by tho naked eyc,
some of which, we are told, aro of more
than suspicious character, being known as
tho originators of ecaldhead nnd other
diseases of the scalp. The author concludes his article hy a caution against wetting the head, recommendiug dry hrushing instead. He aleo recommends the use
of a weak solution of carbonic acid or eulphate of soda ae a cleaning material for
hair brushes.

Japanese Tes.
A Japanese handbill, which we have
fonnd in a package of tea, from Hewes &
tichards, reads thus:
“They aro beth kinds; Yeesay and Sanging; itis the nome of the mountain; there
very much foggy cover the top of
the mountain to the foot are constantly. Thero quality nre euperior and
genuine, Auy person who wns feeling indisposed may try take n enp of it in a few
morning,and will feel much better and good
spirit. With expressly packed fer Tuperial. By Foohing & Co., Yokohama.”
This handbill is evidently written by a
Japanese and it gives us un idea of Japanese progress iu learning our langnage.
Evidently the scholar has confidence thnt
he can muke himself understood, oud in
this he is not mistuken. We learn something from it that may he useful to us.
This tea is presented as a supertiue article,
and its superiority is attribnted to the
foggy mountain-side on which the tea
plants are grown. This suggests that our
eoust range clovntions may be adapted to
tea culture.
California experience in tea planting has
been so iuterrupted by unteward circnmstances, that a fair trial has not been made.
All we have proved is that the plant will
thrive if it arrives here iu good cendition
—better one year old than more; and that
it must be irrigated in summer. The seed
will also germinate, and it is preferable to
transplauting. But the tea nutis very eily.
The oil even gets rnneid and the nut is
useless. Bo enre, therefore, of your seed
before you plantit. We are not certain
that palatable tea cau be made here.
Change of olimate often chauges properties. Herr Schuell’s samples from El] Dorado tea plants were not decisive on that
point.—Alia,
Inaronity of THE Pia From Insury by
Syrvenr Brrrs.—The impression is generally provaleut in the United States that
tho common domestio pig ie an especial
onemy of all kinds of serpents, and that it
is capable of receiving the bite of the rattlesnake and copper-head without the
elightest personal inconvenience or injury.
This same immunity from harm would
seem to oxist in other countries, as a late
writer in tho London Field remarks upon
the fondness of the pige in India for the
cobra de cnpello, and states that he has repeatedly seen them iu conflict, and has observed the pig to be bitten over and ovor
again in tho snout and about the face by
the writhing reptile, and in no instance
with the slightest il] results to the aggreseor. :
Buus Guass For GREENHOUSES.—We
find that Robert Buist, Sr., indorses the
use of blue glass in greenhouses and other
structures for forcing plants, ete. In a
communication to Tilton’s Journal of Horticulture he says:
I applied a coating of Prussian-blue
paint, eix inchee wide, up the ceuter of
each row of panes; the result was electric,
and in 2 few days the plants assumed their
heautiful green color, and the trusses of
bloom came to maturity. The greenhouse
had been used to grow geraniums for bedding purposes, but they had loet their color every year about the first of April. Tho
plants wero completely rejuvenated by the
hlue glass.
Conorep Canpir Licur.—Wax candlee
are made of different colors, but they all
emit a white light. Why may not candles
be manufactured, by introducing certain
chemicals into the material from which
they are made, so as to show a variety of
colors, such as blue, red, green, etc.? By
arranging such candles in tasteful groups,
beautiful effecte may be produced in illuminating buildings. If some ingenioue
chemist will devise a way of embraciug a
cheap chemical with any of the material
used for illuminating caudles so as to render tho light emitted from them of any deeired color, he will make a fortune by his
discovery. —Commercial Bulletin.
Guinra Goup.— The French Journal
Official says that gold production is rapidly increasing in the French colony of
Guiana, of South America. The annual
roduct has eularged from 25,974 francs
in 1856 to 1,685,643 francsin 1871. The
product between 1856 and 1869 amounted
to over ten million of francs. Gold mining industry in Guiana pays an anuual tax
of about tweuty cents per acre, and an export duty of four per cent. upon bullion.

‘Poisonous Exhalations,
Poisonous oxhalations from draius are a
far greater source of mortality than is geucrally supposed. Drince Albert, consort of
Queen Victoria, no doubt come to his end
from such a cause, and the heir ‘‘apparent”
has just beou snatched from the jaws of
death, to which extremity he was undonbtless reduced hy breathing the exhalations
from a defeetive drain, If all the gnards
that are usnally thrown ahout royalty, fail
to secure immunity from such cxposure,
what are we to expect in humble life,
wheu, from neeessity exposure is often
knowingly submitted to, Only two or three
weeks since the English mnil informed us
that a Iarge nnmber of operatives in a factory in Preston, England, became suddeuly ill, and had to cease werk. Several
hnd already died, and others were not expected to recover, An examination showed
that they had been working over a defective drain, No doubt the list of mertality
is largely swelled by such cause, operating
in unknewn ways and quarters in every
large city in the world, to say nothing of
less pepulous neighberhoods. It is time
that the public was taught to have more
regard to such dangereus expesures in less
populous neighborheeds, It is time that
the public was better informed with regard
to the danger from such exposures, and
that more attention was paid to the drainage system ef our cities and houses by
those have who immediate official authority
iuench matters. Defective drainage nnd
impure milk, lead to more deaths than any
other teu or a dozen causes combined.
The Cause of Whooping-Gough.
The germ-theory of disease, which some
pathologists seck to extend so widcly, has
been npplied by Dr. Letzerich to explain
the extremely infectious disease, whooping-cough. He thinks he’has discovered
a form of fungoid growth which vegetates
in the air-passages, and by its irritation
causes the convulsive attacks of coughing.
The expectorated mucous in patients suffering from this disease is said to contain
masses of brownish red spores with occasional threads of mycelium, which in later
stages of tho disease becomo very abundant. The spores are colored blue hy
iodiue and sulphuric acid. These observations were coutrolled first by cultivation
of the epores on piecos of bread soaked in
milk, and further, by introducing masses
of the fungous growth thus obtained into
the trachea, of young rabbits. This was
effected by tracheetomy, but the animals
rapidly recovered from the effects of the
operation, and ina ehort time hecame affected with a cough of a very violent and
noisy character; in fact, a genuine whooping-cough. ‘The rabbits thus effected were
killed, and their air-passages and lungs
found to contaiu an enormous quantity of
the same fungous as that met with in the
sputa from human whooping-cough; and,
in fact, the mucous expectorated hy the
rahhits ehowed precisely the samo appearance.—WMiscroscopical Science.
Carr or tue Frer.—Concerning this
eubject the Scientific American very truly
eaye: ‘‘Many are careless in the keeping
of the feet. If they wash them once a
week they think they are doing well They
do not consider that the largest poree are
located in the bottom of the foot, and that
the most offensive matter is discharged
through the pores. ‘They wear stockings
from the beginning to the end of the week
without change, which become perfectly
eaturated with offensive matter. I] health
is generated by euch treatment of the feet.
The pores aro not repellante but absorbente, and this fetid matter, to a greater or
less extent, is taken back into the system.
The feet ehould he washed every day
with pure water only, as well as tho armpits, from which an offensive odor is also
emitted, unless daily ablution is practiced.
Stockings ehould not be worn more than
aday or two at a time. They may he
worn one day, and then aired and sunned
ond worn auother day, if necessary.
Ammonia aS A Curt ror Snake Bires.—
As many as 8,000 pereons die annually, in
British India and Bnrmah, from the effects
of snake bites. The Inspector of Police
to the Bengal Government now reports
that of 939 cases, in which ammouia was
freely administered, 702 victims have recovered, nud in the cured instances, the
remedy was not administered till about
31% hours nfter the attack, on the average.
In the fatal cases, the corresponding duration of time was 414 hours.
Physical Development.
T. W. Higginsen has taken pains to
compare the vital statisties of several generations of two old New England families,
and he finds to the dismay of those who
mourn the physical degeneracy of woman
since the days of our great grandmothers
that the stock has improved, if anything.
He adds:
No man of middle age can lock at a class
of students from our older colleges witheut seeing them to be physieally supevior
to the same number of college boys taken
twenty-five years ago. The organization
of the girls being far more delieate and
complicated, the sume reform reaches thei
less premptly, but it reaches them ut lust.
The little girls of the present day eat better food, wear more healthful clothing and
breath more fresh air than their mothers
did. The introduction of India-rubber
beots and water proof cloaks alone hae
given a fresh lense of life to multitudes of
women who otherwise would have been
kept housed whenever it so much as
sprinkled. It is desirable, certainly, to
venerate our grandmethers but I am inclined to think on the whele that their
great-grauddaughters will be the best.
Bic Sunpay Dixyers.—A Sunday’s dinner is made the most sumptuous meal of
the week in n great mony heuscholds, and
the guests retire from the table more like
gorged anacondas than intellectunl human
beings, with the result that during the
whole afternoon there is such an amount
of mental, physical and religious sleepiuess, if net actual etupidity, that no duties whatever are perfermed with alacrity,
efficiency, and acceptableuess The Sunday dinner mado of a cup of hot tea, eome
bread and butter, with a slice of cold
meat, and absolutely nothing else, would
be wiser and better for nll; it would give
the servants more leisure ; the appetite
would be as completely entisfied half an
afterward, while body, brain and heart
would be in a fitting condition to perform
the duties of the Sabbath with pleasure to
ourselves, with greater efficiency to others,
and doubtlese with larger acceptance to
him toward whom all our service is due,—
Hall's Journal of Health.
Exrosep Arms.—A very distinguished
Paris physician says: ‘‘T believe that, during the twenty years I have practised my
profession, twenty thousand children have
been carried to the cemeteriee, a sacrifice
tothe absurd enstom of exposing their
arms, Putthe bulb of athermometer into
a baby’s mouth and the mercury risee to
ninety degrees. Now carry the same to its
little hand; if the arm be bare and even
cool, the mercury will sink to fifty degrees.
Of course, all the hlood that flows through
these arme must fall from ten to forty dogrees below the temperature of the heart.
Need I say, when these currents of the
blood flow back to the chest, the child’e
vitality must bo more or less compromised ?
And need Ladd that we ought not to he
surprised atthe frequently recurring affections of the tongue, throat, or stomach ?
I have seen more than one child, with habitual cough or hoarseness, entirely relieyed hy eimply keeping the hands and
arms warm.”
Smeunar Deata.—Mr. E. (', Chambere,
the Park street etation agent of the Medforth branch of the Boston & Maine railroad, met with his death ina very singular way, eome days since. His little
daughter was sick with the diptheria, and
he put his hand on her mouth for eome
purpose or other, and the child seized
upon his hand and bitit. The marks of
the teeth were very slight, comparntively,
but the ekin was hroken slightly, and the
poison from the tecth was transmitted
through Mr. Chambere’ eystem, and after
a week’s illnees, during which hie body
hecame much swollen, he died.
Tue prospects of medical education for
women are brightening. ‘The medical faculty of Moscow, Russia, it is etated, have
not only decided that the privilege of acquiring a thorough medical knowledge
would be of utility to women, hut have
“yesolved to admit them to the educational
courses and lectures of the University, and
to the privilege of following all the labors
of the Medico Chirurgical Academy.”

Bellovue Hospital, New York, and has

Curr vor Diprueria.—A eimple treatment of diptheria may be found in the use
of lemon juice. Gargle the throat freely
with it, at the same time swallowing a portion, so as to rcach all the affected parts,
