Mr.. jackson, PRINCIPAL of the Delaware
Institute (forTerly Taylor x Jackson's
Academy delivered a lecture at the Free
Reading Rooms of tho Mechanic Ins Iitute.
corner of Filth and Market streets, to
large and attentive audience. In lieu of
any other report, we publish the following
letter from mechanic who listened 10 il
Hsssrs. Editors with your consent
will act for once 80 reporter. Attracted
by the notice of lecture to he delivered
by Prof Jackson of our city, upon "The
Air We Breathe" | found myself one OF
the interested auditors who listened to aud
witnessed the beautiful experiments,
demonstrating the elastic qualities. and
specific gravity Of "The Air We Breathe"
Few subjects are Of 80 much Interest to
the practical mlnC as are those Of Natural
Philosophy.
The demonstrations of science are not
.lly curious, but stupentous. To tell
n, 10 be goes about biz daily oecupa-
lions, that lie all the time sustains
wsight or pressure, enormous, when emu
mefuted IN figures, and one that would
crush him If the neutTAliZing or balancing
pressure was removed, is to speak in rid
dles TO tell him, further, that this press
ure is balanced by an equality OF the
upward, downward and sideward tendency
Of It's pressure, and that the removal OF the
upward pressure frOn under the small area
Of lis Land would hold him to Il given
spot, would cause him in all probability to
doubt your sanity; yet It is fact capable
Of demonstration. To assert so much as
! that the weight Vi air upon the surface Of
an apple Is enough t0 force the core Out OF
/ il would he downright toOllshness were We
not convinced from having seen 1t done.
! All Of this, aud much more, was beau
tiiullS demonstrated by Prof. jackson be-
\ fore the Workingmen's Institute GU satur-
day evening. Tue Professor eyinced no
desire to display his rich fund of knowl-
edge In hlgh-sounding, technical phrases,
and is entirely devoid Of mannerism in
his style.
In language perfectly fitted to, and com
pretended by his audience, he told us
many pleasing and useful iaels. His great
iiberaiity In using his tine aud elegant
apparatus for The purpose OF mstructing
US, readers lis his debtors, aud We desire
TO express tue grateful feeling, we feel
sure, is shared by lis auditors.
The lnstitute under whose direction tho
lecture was given, Is In itself an object Il
commend to every Que who desires to aid
10 the spreading Of kuoBledge, and W,
feel assured that If our public Spirited
OitiEens could realize how fully The FIRE
qneuters OF the reading room appreciat,
the fayOrs conferred the institute would
bs amply sustained and empowered TO add
to iis means Of good.
The wurkingmeu Of our city should be
come members of the Institute and eucOur
age the Executive Committee (whos,
labOrs are entirely gra:uit0us), and tn
contributors, also, should be encourage,
to do more, by reason of our espresso
willingness 10 DO for ourselves all we can
The committee have decided 10 form
membership, aud invite Us to euroll on
names IN a record to be kept for that pur
pose, the membership fee being set ut th,
very los figure of 30cents per anbum, an:
ILLS not obligatory, mt, we think, desira
ble. Ms It gives Us an opportunity to becon,
s-srers with them Of the honor % dOiul
so reputable q work, and certainly We
CAP all do this little.
Hoping the Institute will be amply aus
tanned, we gladly give il our cOmmendn
tion. Yours, ARTISAN.
