Subject: Dating a given magnetic declination
To: Multiple recipients of list GIS-L <GI...@UBVM.cc.buffalo.edu>
I have an instrument which incorporates a small compass. The magnetic
declination engraved on its dial is between 22 and 24 degrees West of
North. I am trying to find out when that instrument was probably
manufactured for use in Princeton N.J.
This information is needed to authenticate the provenance of the instrument,
Namely Joseph HENRY, when he was a professor at Princeton University.
Any information would be greatly appreciated.
PS: This is a repeat of same query which somehow was misplaced because I had
the unfortunate practice of sending mail to GIS-L while logged in as "root"
This system is a single user system (most of the time) and I seldom login
to my home directory!

This is a GIS oriented complaint which translates in english to:
"Rivers enter the sea and the sea returns nothing"
The foregoing terminated a letter from a 19th centrury scientist who was
trying to locate a communication made to the French Academy of Sciences
for their October 22, 1845 session.

Recently looking through my historic data base I ran accross the following
which is an excellent example of technical writing not geared to the
average reader's vocabulary. I had to learn this by heart and recite
it in less than 3 minutes while in college in 1949. It was actually
written by Arthur D. Little (probably as part of a government contract).
I am sending this to indicate to the GIS-L contributors how much of the
stuff submitted sounds to me!

SUBJECT: Technical Description of the Turbo-Encabulator
TO: Engineers Concerned
1. INTRODUCTION
For a number of years now work has been proceeding in order to
bring perfection to the crudely conceived idea of a machine that
would not only supply inverse reactive current for use in
unilateral phase detractors, but would also be capable of
automatically synchronizing cardinal grammeters.
Such a machine is the "Turbo-Encabulator". Basically the only
new principle involved is that instead of power being generated
by the relative motion of conductors and fluxes, it is produced
by the modial interaction of magneto reluctance and capacitive
directance.
2. DESCRIPTION OF MACHINE
The original machine had a base-plate of prefabulated amulite,
surmounted by a malleable logarithmic casing in such a way that
the two spurving bearings were in direct line with the
pentametric fan. The latter consisted simply of six hydrocoptic
marzelvanes, so fitted to the ambifacient lunar waneshaft that
side fumbling was effectively prevented. The main winding was of
the normal lotus-o-delta type placed in panendermic semi boloid
slots in the stator, every seventh conductor being connected by
a non reversible tremie pipe to the differential girdlespring on
the "up" end of the grammeters.
Forty-one manestically spaced grouting brushes were arranged to
feed into the rotor slip-stream a mixture of high-S value
phenylhydrobenzamine and five per cent reminative
tetryliodohexamine. Both of these liquids have specific
pericosities given by:
P = 2.5 * Cn ** 6.7
where "n" is the diathetical evolute of retrograde temperature
phase disposition and "C" is Cholmondeley's annular grillage
coefficient. Initially "n" was measured with the aid of a
metapolar refractive pilfrometer (for a description of this
ingenious instrument, see L. E. Rumpelverstein in "Zeitschrift
fur Elektrotechnistatische Donnerblitze" vol. vii), but up to
the present date nothing has been found to equal the
transcendental hopper dadoscope (See "Proceedings of the
Peruvian Academy of Skatological Sciences" June 1914).
3. DISCUSSION
Electrical engineers will appreciate the difficulty of nubing
together a regurgitative purwell and a supramitive
wennelsprocket. Indeed this proved to be a stumbling block to
further development until, in 1942, it was found that the use of
anhydrous nangling pins enabled a kryptonastic bolling shim to
be tankered.
The early attempt to construct a sufficiently robust spiral
decommutator failed largely because of a lack of appreciation of
the large quasipiestic stresses in the gremlin studs; the latter
were specially designed to hold the reffit bars to the
spamshaft. When, however, it was discovered that wending could
be prevented by a simple addition to the living sockets, almost
perfect running was secured.
The operating point is maintained as near as possible to the
H.F. rem peak by constantly fromaging the bitumogeneous
spandrels. This is a distinct advance on the standard
nivelsheave in that no dramcock oil is required after the phase
detractors have remissed.
4. CONCLUSION
Undoubtedly the Turbo-Encabulator has now reached a very high
level of technical development. It has been successfully used
for operating nofer trunnions. In addition, whenever a barescent
skor motion is required, it may be employed in conjunction with
a drawn reciprocating angle arm to reduce sinusoidal
depleneration.
