DEAR BULLETIN My farewell was
| premature after oil, as since bidding you
adieu,1 have been cogitsting, and think
have hitupon your passing anger sgainst
E-c. 1 suppose il was because dill not
roply directly to your conclusion about
things BY ocular proof in your remarks
of the 18th Of April. You should have
gone further, and said that AS Prof Tyn-
DIAL could not demonstrate the
existenes of inyiiiblo Ugh. BY ocular
proof, 1t ia useless to continue scientific re-
search, because there is nothing except
that which can DO shown ocuiarly. On
the contrary, thero are groat many
things which people cant see. ..s.. ..
Now, lot US take a journey together.
Suppose THE BULLETIN receives Its tele-
graphic Dispatches a. niae O'Clock ut night
&c suggests that you tako the reports
yourself, thereby saving the cost Of getting
them through the telegraph Office. You
accept tho suggestion, and we start for
the levee, where are to be folnd the tele.
graph wires. Arrived a. the proper place,
Dr. John sayr 1t is dark; We must have
some light.
Eel will run dowE TO tho Sun
Office and got Mr.. Davis to throw ray or
two in tho direction OF the wires. You
wait hero until return.
Mr.. Davis complies at once and when
l get back ! sea DR.. John in position, pen
Gil In hand, and all his peculiar angles in
full play. ...
&c Why don't you take the reports ?
DR.. John--Bocause l can't see them. If
you want mo TO believe they arc thoro,
show that by ocular proof. We proceed
to the telegraph Office aud find that the
last of the reports arc just in. The subtle
medium can't be seen passing along the
wire, but it produces an effect which man
perceives easy enough. SO in Pro-
iossor Tyndals theory of light.
He says parts of light can't
be seen, but chemical effect is pro.
duced, the origin OF which he traces to
those unseen rArts Of light .f... .u
Now, by some rapid transit (say by a
"Gr.phic" Balloon the next morning we
arc in London. After tho Refreshments
of the bath and breakfast, We start for
Prof. Tynd ais abode, which is not hard
to find, because most intoligon. people
nowadays know WHORE the great
lights of science are to be
found. Wo arc wslconed by
Prof. Tyndal as representatives Of tho
city of Cairo. which ia acknowledged to DO
ono of the forces of the great republic.
Upon making known our GRAND, Prof.
Tyndal invites us TO his labratory, and
producing prism, soon shows the spec
trum. Beyond the visible spectrum is
something else, says tho professor, and he
shows from chemical effect tho existence
of elements not before recognized. ,.
DR.. John-Whst are tho elemsnts2 e. !
Prof. Tyndal-Invisble light.
DR.. John-How do you know?
Prof Tyndal-I don't mako any posi-
tive assertions about IL, but l say, TO tho
best of my perception, they are paris OF
light not before recognized.
DR.. John Forgetting himself--think-
ing he is in the presence of his legislative
chums How tho devil can you call that
light which can't be seen
Prof. Tyndal--The elements spoken Of
must have name, and l think
you will agree with mo that it
is very natural TO call them light;
and, as tho eye cant detec. it, l call it in
visible light. ....-...
DR.. John--I won't acknowledge it. j
say there is nothing except that which can
DO plainly shown by ocular proofs
Pool. Tyndal--l will consider what you
have said, and if come to your conclu-
zion will move to Cairo and take a posi-
ton on The BULLETIN, ,,, .,. .-. |
Then ws converse upon general
subjects, and after mutual express
joins ,o Of good will ~ retire, DR.,
John mentally saying that no had
upon the professor y lasting
benefit. .....-. -1lJ
We were ofesed tho freedom OF tho
