It is now we'll recognized fact, states
G medical journal, that the structures of
the eye, especially the cornea and
conjunctiva, are subject to 1nalarial af-
fections, periodical in character, differing
from the usual affections of these parts,
but involving actual tissue change, and
amenable to quinine or other animal
arial treatment. Some liberation or
abrasion of the corneal epithelium may
occur, or intra-ocular hemorrhage dur
ing the cold stage of paroxysm,
By private gifts, Japanese fellow
ship in economics has been established
at the University of Wisconsin, and Mr..
M. Shiozawa of Tokyo, Japan, has been
elected to the fellowship for the coming
year. Mr.. Shiozawa is highly recon-
mended by two disting uished Japanese
professors, Professor Iyenage Of the
Higher Commercial College of Tokyo,
Japan, and Professor Motora, of the
Imperial University of the same city.
He is spoken of as one of the talented
young mon of Japan, and it IS expected
he will do great work for his native
country. He has already graduated from
Japanese college and has published
results of his work. He is now on his
way to this country to enter upon his
studies at Madison.
That the separate sexes of flowers is a
mere question of nutrition, as first sug-
gested by an American botanist some
twenty years ago, is now the accepted
doctrine of botanists, according to The
Independent. 1t appears that whether
a flower is finally male or female de-
ponds on the amount of nutrition avail
able, or the young germ Is capable of
assimilat1ng, at Or about the period Of
formulation. Female flowers form only
when the highest nutritive powers exist;
male flowers, only when the nutritive
conditions are the least favorable. A
young feritiIized germ may, therefore.
become male or female, according to
circumstances. Even so highly differen-
tiated male product as the ament, or
catkin, is found to have female organs
among the males when the nutritive
conditions are favorable; and it has been
recently noted in America that flowers
of both sexes have been found in catkins
nf xryhi ri, nh
records the same occurrence in the
catkins of the common hazel. Similar
phenomena are we'll known in Indian
corn where grain is not uncommon
omong the male flowers forming the "tas-
sel.''
The efficiency of boilers, engines and
dynamos is now so high that little i'm
provement can be expected. On the
other hand the optical efficiency of
nearly all known sources of light is
extremely low, these being the latest
determinations: Oil lamp, 0.073 per cent
ordinary gas flame, 033 per cent; ele;-
trio incandescent lamp, l per cent; arc
1oAPs c'O'o POA OOAOs AdSuSo1ulA 11SuU,
Is per cent; sun about 81 per cent;
Geissler tube, 32.7 per cent. The FREELY
is hardly a common source of light, but
it is an example of high efficiency, pract-
ically 100 per cent of the energy expen-
ded giving visible vibrations. It is worth
noting says the Electrical Plant, that
in the various artificial sources of light,
the greater part of the energy dissipated
in producing non-luminous rays is ex-
| pended in the production of vibrations
| having a wave length of about twice
that producing the sensation of light.
A very superficial examination, however,
shows that there is little hope for sub
stantial improvement of the many forms
of lamp in use. The Ge1ssler tube is so
far ahead of these ordinary lamps as
source of illumination that the attention
which has been turned to it by Mr.. les
la and others, with a view to producing
a really practical lamp in this form,
would appear to be we'll merited.
