nc ODSeFNdtlOnS OF Professor 0OluDOII,
of Moscow, have convinced him that ap-
pendicitis is not only a contagious disease.
but that it sometimes occurs in epidemics
1t was unusually prevalent in Moscow last
year To illustrate, Professor Goluboff
mentions that in a small boarding school,
where IN several years there had not been
a single case of appendicitis, he treated
seven cases within two months.
Monthly current charts of the Atlantic

flee from about 1880 mariners logs ex-
tending back to 1880. Among the interest
ing facts brought to light is that the Veloc-
ity of the gulf stream varies with the sea-
son. being about 100 miles a day in June,
not more than seventy miles in October
and November, and at times not over
twenty miles. The Guinea and equatorial
currents also undergo considerable varia-
tons with the time of the year.
British astronomers are taking a lively
interest in the next eclipse of the sun-to
take place on Jan. % 1S9S-and the
royal astronomical societies are ar
ranging to send out three parties of OBJ
servers. The central line crosses western
India, the duration of totality at the most
favorable stations being about two min
utes. The prospects OF fair weather are
considered exceptionally good, as the jan
uary skies Of India south of Bombay are
remarkable for their freedom from cloud.

A new and simple method of studying
the stomata or breathing pores of leaves
has been suggested by Mr. Francis OAR
win. 1t consists in the use of Chinese
sensitive leaf" thin sheet of specially
treated horn, which acts as a Microscope
and curves away from the source of mols
ture If the stomata of leaf on which it is
laid are open, remaining stationary If they
are shut. A simple scale may be made to
record the degree of curvature The APP
paratus opens the way for a variety of eX
periments by home botanists, and shows,
among other things, that the stomata regu-
larly close at night as the leaves pass into
something like a sleep, often opening
again in the darkness if that be long con-
tinued.
Natural perspiration and the extracts
prepared from it have been found by NJ.
Arlong, French biologist, to produce
poisoning when injected into the veins,
large doses causing the death of dogs and
enthusiastically within three days, though
sometimes not for several weeks. Smaller
doses produce corresponding effects. The
degree of toxicity varies with the environ
ment of the subject and the mode of pre-
pairing the extract, the perspratiOn attend
ing arduOuS muscular labor being 20 to 30
per cent. more poisonous than that pro-
duced under ordinary conditions. Artificial
sweating yields the least poisonous per-
spiration, unless the patient is suffering
from cold, when the perSpiration is de-
cidedly poisonous.
Some astonishing changes in the phys
ical type of races as d result of inter-
course with foreigners have been pointed
out by NJ. Albert Gauttard to the French
photographic Society. The Japanese, who
since the revolution of 1868 have been rap
idly adopting European modes of life, are
losing the eccentricity of their eyes and
the prominence of their cheek bones, while
recently-born children have less flattened

so yellow. Europeans settling in Japan on
the other hand gradually lose the rosy
color OF their skin. and tend to acquire
eccentrcity in the eye Another instance
is reported by Adhemar Leclere, who has
observed in Cambodia a striking change in
his countrymen, the French residents soon
beginning to acquire the type and the gait
of the natives.
The aerial sea that surrounds the earth
is in constant but unequal agitation, GER
tain parts of it being little disturbed, while
other parts are rapidly varying from very
high barometric pressure, marking a heap
ing up of the atmosphere, to very low pres
sure. A study of the "centers of action of
the atmosphere" or regions of mean baro-
metric maxima and minima has been made
by DR.. H. H. Hildebrandsson, Of the Mete-
geological Observatory of Upsala- The
monthly differences of pressure from the
mean were calculated for the years 1875 to
1884 at Sixty-eight widely distributed sta
tons. and show that the differences are
greater in winter than in summer and in
crease from the equator toward the poles,
the barometric variations at certain locali-
ties-as the Azores and the vicinity Of Ice
land-being almost opposite in sign, and
that the greatest differences are found in
January and July in the vicinity of Green
land and Iceland, on the one hand and the
north of Russia, between the White sea
and St. Petersburg, on the other. The fact
seems to be established that a kind of
oscillation exists at all places in the pres
sure of air between a center of action Of
high pressure and adjacent center of
low pressure
