SAND GLASS STILL NEEDED.
Used Nowadays I'm sickroom, Music
Room and Kitchen and ON the
Table.
(New York sun.)

There ara hour glasses, tneee-minute
glasses, and so on (; and these several glas-
sss are used for many different purposes.
The hour glass is mostly rs6d in the sick
room and In the music room. In the
slckroom 1t IL used as guide in admin
istering medicine. With IL there IL no
need Of watching the clock, no doubt
about when the last desc was given, or
anything Of that sort; out wnen the eand
In the glass has run out the medicine Is
given ami the elass is turned, aud so on.
In the music room 10 lie used for the oon-
venienoe Of the teacher, and ais, for the
guidance OF the pupil. In the first case
there is no occasion for consulting watch
or olock. The hour glass stands there on
the piano, and It Is simply turned and
set going at the beginning OF the lesson,
TO mark the hour with certainty. 1t IL
used for pupils to practice By. With an
hour glass in plain vlsw there Is no ocna-
sion for running of to see the time, or
| for turning {, look at q clook In the
same room. Here, fgain, started ct the
beeip ming OF the lesson, the hour glass
marks the time without any doubt or
uncertainty, and, though the pupil may
/ e glad to see the last of the sand run
through, the hour glass Is tiInekeeper
that cannot be disputed.
Haif-hour glasses are put to the same
uses as hour glasas, and thtss and hour
glsssss as well are occasionally Used by
teachers In school or classroom s.
Fifteen -minu glssses are used to .
limited extent for medical purposes; and.
In marking this division Of time, anu the
sand giais goes into the kitchen Is an aid
to exact cooking. There are aisa made
ten-minute glasses, OF which q few are
used for medical purpc sss, and this glass
Is also sd In the kitchen. There 10
hve-minute glass which IL largely
kitchen glass, ussd to boil eggs by and
for other purposss; and the thrse-minuts
SAND glass Is called an egg. boiler.
Besides the sand glas used for these
various household or domestic purposes.
there are sand gases used for scientific
and other purposes. A sand glass 10 used,
for instance, when the log 10 cast from .
ship; . sand glass 10 attached to . ma
chine made for indicating and registering
the velocity OF the wind. this method Of
marking on period Of time being much
more convsnisnt than holding q watch

Sand glasses are made In this country,

France and England. The sard used In
sand giasses 10 specially prepared BY thor

baked dry and perhaps ground into
requisite fnensfs and uniformity. as
wedged in the opening between the two
pnrts Of the glass. 1he sand 10 intro
duced into the glass through an Oh enins
left for that purpose In the end of one Of
the butts, that opening beiug then
sealed. The right quantity in each sand

cd OF timing the how from enc part Of
the glass to the other. In glasses OF the
same size the opening between the two
bulbs, as the glasses are produced by the |
glass blower, woud be approximately the |
same, but It would be practically impos-
sible to get them absolutely the same, |
and sands might vary more or lees; 80 |

Hourglasses and sandglassss of small |

oi sely the same form In which they have |
long been familiar to the mind; If not |
from actual use. at least from Pictures,
as for instance In the drawing OF Father
Tins with his scythe and hourgiass.
Many of The smaller glasses for various |
uses are now made with cylindrical metal
frames or holders, having large openings |
