DOGS anyone, besides the United

and why the word lobster came to be
used in a slangy way? asks the Boston
Transcript. We have heard 1t do duty
at variety theaters and on the street for
some time, but we have never felt quite
justified in taking 1t up for home use. 1t
has seemed wholly untitled for polite So
cIety, though perhaps that is because we
have not known how it entered the vau-
deville stage. But now that in our great
! and general court the word comes up and
does some excellent and effective work
through one of it's most dignified and
worthy leaders. we may see it adopted by

teresting facts relative to the number
of dust particles which the air may con-
tain. In an open London suburb he
found 20OO0 dust partioleE in a Gu
bic centimeter Of air-eqnal to about
0.061 of a cubic inch--whi.e in yard in
the center of London the number
amounted to 100000. The air was loaded
to the extent of about 800 per cent. more
in the city than in the suburb. 1t will
be observed this calculation refers to
dust particles, and We must not make the
mistake of regarding this term as synon-
ymous with microbes nor must we think
of every germ as necessarily being dis
ease-producing organism. DR.. Macfayden
found in the open air of London only one
microbe to every 100000 or so of dust
particles. In the air of room among
1874, 100000 of dust atoms there was only
one germ. This is comforting to know,

sunshine streaming through a chink in

Mr.. Kamm has invented a remarkable
device which dispenses with the long cell

ing pictures, a circular glass plate TAX
ing the place of the long film, says Lol-
den Science Gossip. On this plate the pic
| lures are made in a spiral curve. A re-
markable feature of the Kammatograph
| is that it serves the purpose of camera
and protector combined thus dispensing
with the use of two apparatus, one for
taking the photographs. the other for dis
playing them, as is the case with the
ordinary celluloid film. All that is neces-
sary is to have a circular glass plate
| ready sensitised, and then placed within
| the instrument, in dark room, when the
amateur photographer, after arranging
the apparatus IN position, simply removes
| the cap and turns the handle at the re-
duired speed until he reaches check
| which informs the operator that about 60
| pictures have been taken on the plate
| The cap is replaced the instrument re-
turned to dark room the negative plate
developed, and, when dry, printed in the
ordinary manner by contact. Thus it will
be seen that moving pictures of important
or entertaining events may be taken with
this simple arrangement by persons of
ordinary ability and exhibited to their
friends within an hour or two on a screen
showing moving pictures about feet
| square in clear detail.
M. dArsonval made some astonish-
ing demonstrations with liquifed air the

ural History, says the London Times BY
enormous pressures he reached a tenn
perature of minus 1870 cent grade. The
iiquihed air was contained in a double
sided silver, covered bottle, and did not
evaporate. Experiments with india-rub-
Der bottles showed that, under the inHu-
ence OF the intense cold, they became as
hard and brittle as glass. The rubber
could be pu.verized, but became elast C
