SCIENTIFIC MISCELLANY.

Science y making fapid progress ia
utilizing what have been regarded as the
waste products of the Garth. In many
parts of Sweden great quantities OF the
remains Of moses which lived centuries
AGO have accumulated. II seems quite
surprising that this material can have any
value, but it has been discovered that
good paper can be made from it, and a
msaufactory is reported to have commenc-
ed making such paper, in various thick
nesses aad quantities from tissue to sheets
thrse-quarters Of an inch thick.
Dr.. John V. Shoemaker, in late pa
per, gives. cutting and shaving, the wear
Ing of head-ooverings and uncleanliness
= prominest causes Of injury to the hair
He also states that modern investigation
~ demonstrated that thinning and loss
a hair are often due to the defective &C.
ton Of tho serves Of nutrition. Fruitful
sources Of this defective action are over
taxing Of the physical powers, excessive
bsain work, csowding the mental faculties
Of children, loss Of sleep, incessant cares,
anxiety, grief, excitement, sudden dcpres-
sion and exaltation Of spirits, irregular
and hastily bolted meals, lack Of rest and
recreation, abuse Of tobacco and spirits,
Of tea and coffee, and Of all kinds Of
drugs.
At the Moutsouris Observatory care
full study has long been made Of atmos-
pheric germs. These are found TO be
always present 10 great number and va
sisty. Their distribution is, however
greatly affected BY the season. OF spores
belonging 70 noulds tho following mum
bers are given as an average for each cubic
meter Of air. In January, 7; February
Z; May, IL; june 49, August, 30, Octo
Der, IA; December, T. OF bacteria cacl
cubic meter Of air averaged 80.
Moas. Barthelemy has reported to thu
French Academy some observations OF
IL Incubation Of eggs laid by q hen hav
Ing fowl-cholcra. All such eggs failct
70 hatch, although the development Of tn
snbroys commenced and continued fo1
several days ~ in normal eggs. At {
particular stage--just the point when thu
embryo begins to assume the special fca
cures Of the chickeA--sll growth ceased
The blood Of the diseased eggs was then
found to be full Of the minute organism,
peculiar to fowl-cholera.
Messrs. David 8. Jordan aud Chas II
Gilbert have prepared synopsis Of al
known North American fishes, including
both fresh and salt water species Theil
Gss embraces 1,340 species, belonging t.
A87 gcaera and 1870 families.
From experiments upon insects Herr
Hauser, Of Erlangen, has shown that thei'
sense Of smell exists in tho antenne
His further studies have convinced him
that tho external organs Of smell consis,
Of series Of cones or cavities filed with
. serous 6uid-which may BE- regarded
- out-foldings Of the epidermis. tt
th1ss are connected staff-cclls, from which
nerves stretch through the antcnnn to
the braia. The organs are most highly
developed in insects which seek food by
smell. Bees and wasps have the greatest
number Of smelling cavities and cones,
The honey-bss having fourteea or fifteen
thousand cavities and about two hundred
cones in each antenna, and the leaf-wasp
. somewhat smaller number. Plant eat
ing Ais have only Ave or six cavities to
each feeleR.
Moas. Michslson expects to make a
Thermometer 20 sensitive y to measure a
shousaadth part Of centigrade degree.
The expansive substance is hardened
rubber.
The following conclusions are credited
to Mr. Aiken . the result Of extensive
observation and experiment. Whenever
vapos eoadeAses in the atmosphere, the
condensation Is always made On solid
auclsss, which is furnished BY particles
Of dusa Without dust there would be
neieAes nists nor clouds, and the super
saturated cir would transform every
objess upon the esrth's surface into con-
dsnser upon which it would deposit its
excess Of water. Whenever the breath
becomes visible in . cold atmosphere it
demonstrates the impure and dusty con.
ditioa Of the air. The foam Of the Sea,
meteosic matter, and fires are fertile
sources Of the dust and impurity.
The later Danish explorations i. Green
land have shown, according to Herr Rink,
that the southern district of .Julianshsab
confains about one hundred localities
