Ways & Means

Will sound when
transmitted in this
way be as long in
the travelling as in
the open air?
If so, at 1000 pr
second it would
above 5 1/4 seconds
travelling a mile

Could a Whisper
be transmitted to such
great distances?

Could the ordinary
voice?

Would it remain
articulate?

If not, would
the notes of music
retain their pitch?

If so, conversation
might be carried
on by org trumpets
or rather by organs
notes being put for
letters.

24 notes being too
large a scale, the
alphabet might be
contracted within the
compass of an octave
by means of different
stops

Half notes should not
be adopted employd
as not being sufficiently
distinguishable

Stops {Wood Flute
{Metal plan Cornet
{Metal with a reed Bassoon & Hautbois.

Ways & Means

To ascertain whether
the persons with whom
there may be occasion
to converse are ready
for conversation, certain
words of course
should be exchanged
at certain periods

Would curves in
and angles make
any and what
difference?

Half a mile the
extent of Panopticon
Hill grounds would
afford a very instructive
experiment with
in respect of a
distance of many
miles: if there were
no perceptible diminution in
1/2 a inch, there
might be none in
many miles: if
there was a perceptible
diminution
in one case, it
would afford grounds
for estimati conjecturing
the degree
of diminution in
the other.
