NOTES IN SCIENCE.

AMERICAN vs. fOREl6N hCR0SCOpEA
Prof. Seaman Of the Howard Univer.
sity has collected the testimony of the
owners of over 1000 microscopes
in use in twenty of the leading colleges,
the department ofiagriculture, geolog-
ical survey, microscopical societies,
etc, and finds that $50 are American
and 434 of foreign make. From the
extracts which he publishes it is appar-
emit that the native instrument is rapidly
growing in favor-the University of
Michigan believes "the best instru-
ments are made in this country. Col
leges pay no duty on their imported
instruments; hence their selection is
not affected by the tariff. DR.. Seaman.
say: CAS- to the principle, am an
American citizen and teacher, and.
other things being equal, I prefer to
buy my microscopes of my neighbor,
who will send his children to my school,
and who. il he grows rich making mi
croscopes, may endow my college,
IT, to be interested in my success or
lbat Oh my country. know professors
of political economy do not teach this
view; but most business men act ac-
cording to it, though the principle may
be unwisely applied Under it as the
rule of our national polity we have
made the best and cheapest watches,
telescopes, and apparatus for the in
vestigation of radiant heat; and, if the
users of microscopes will only coop
crate fairly with the makers thereof we
shall soon have the best and cheapest
microscopes the world has yet SEEM"
PREHISTORIC AMERICA.
Intelligent Americans will be inter-.
ested in the forthcoming meeting of the
International Anthropological Congress
which will begin its seventh session in
Berlin on Oct next A series of four
sittings will be devoted to America;
Prehistoric and Present" and the SUBJ
ject will be discussed in its largest an
thropological significance. The con-
gress invites the cooperation of all who
are interested in the civilization of the
new world, its inhabitants before and
at the time of its discovery by Colum-
bus, their origin or afinities, social de-
velopment, racial differences, the in
PRODUCTION of domestic animals. Guilt
walton of food plants, and generally the
conditions which underIie the progress
and expansion of the western hemis-
phere. The first congress of the kind
was held at Nancy in 1875, the second
at Luxembourg in 1877, the third at
Brussels in 1879, the fourth at Madrid
in 1881, the fifth at Coppenhagen in
1883, and the sixth and last at Turin in
1886. The considerations that decided
the choice of Berlin for the next meet
ing were chiefly her great wealth in
archaeological collections illustrative of
prehistoric America and the prominence
of her Investigators in every aspect of
the physical and moral development of
the new world.
POWER OF THE MICROSCOPE.
In his address before the Royal Micro
scopical Society. Sir Henry Roscoe
treated the hundred-thousandth part of
an inch as the limit of visibility with
the highest known magnifving power.
Mr.. Crisp, however, said that the limit
of visibility can hardly be DEFINITELY
stated, but he assumed it to be b yond
the five-hundreth-thous part of
an inch. DR.. Dallinger, the President
of the Society, corroborated Mr.. Crisp's
observations, and said that he himself
had certainly seen objects which were
between the two-hundred-thousandth
and three-hundred-t housandth part of
an inch.
