Weights and Measures in Sehool-
In Holland have never seen elsewhere,
but that which ought 10 be in every
school-the actual weights and measures
of the country. These were used not
only as means Of conveying useful
knowledge, but ofmental exercise and
cultivation. There were seven different
liquid measures, graduated according 10
the standard measure of the kingdom.
The teacher took one in his hand, held
il up before the class, and displayed itln
all its dimensions. Sometimes he would
allow it 10 be passed along, by the mem
bers of the class, that each one mi ght
have an opportunity to handle II, and 10
form an idea OF its capacity. Then ne
would take another, and either tell the
class now many measures of one kind
would be equivalent to one measure oi
the other, or, lfhe thoughithem prtpared
for the questions, he would obtain their
judgement upon the relative capacity OF
the respective measures. In this way
he would go through The whole serles'Te
fc,ring from one to another, until all had
been examined, and their relative ca.
pacites understood. Then followed
arilllmetical questions, founded upon The
facts they had Iearned-such as, if one
measure full Of wine cost so much, what
would another measure full cost, design
aling The measure, OF four, or seven other
measures full ?-The same thing was
then done with the weights. Ii is easy
TO sec how much more exact and per-
manent would be the pupils knowledge
of ali weights and measures, obtained in
this way, than if learned by heart from
the dry tables in book; and also how
many useful aud interesting exercises
could be founded upon them by skilful
teacher. Ibelieve it would be difficult
to find many men in the community, Of
middle age, who can now repratall th"se
tables of weights and measures, which,
as schoolboys, they could rehearse So
volubly.; or who, were they now TO see
actual sets ofweights and measures, could
call all The different ones by their true
names, or distinguish each denomination
from tho others ifnot seen in jux.a-
position with them. Havinglearned the
tables by wrote, the words have long ago
vanished from The mind. and the ideas
were never in it.-Horace Man.
Mechanics among the Aneients.-
The town OF Pompeiiwas supplied with
nalcr by means ofpipes ofiron, lead and
OF baked clay. The museum of the dug
out city contains bronze cock, ola,
large size, which has two communicating
pipes. The spashing Of wafer, Which.
has been suIong Theoretically sealed, Can
now be heard in it. 1t is proved, both
by the fountains and fresco painting, that
the Pompeiians were acquainted with
that law OF wa;er, which causes the fluid
flowing in d pipe to ascend to the level
ofitssource. II has al ways bcengravely
asserted that this property was not
known to them, OF tits presumed they
wouldno, have carried ther aqueducs
arches of masonry. Perhapsin somr of
these cases, there may have been labor
lost, but they must have known well the
lmpossibiIity of making masonry 10 resist
the hydrostatic pressure where there
was great head of waIer.-Sc1entJfc
