Of the Invention of Telescopes and Microscopes, with their First Improvements

Screen Shot 2015-08-08 at 11.10.58 AM.png


I happened to run across an article by Joseph Priestley  [Priestley, Joseph, LL.D, F.R.S., Of the Invention of Telescopes and Microscopes, with their First Improvements,The Literary and Biographical Magazine and British Review, vol.10 (June,1793): pp. 407-11.].

What I found so interesting with this article was that I could not find it listed in any of the standard bibliographies of his works; not even in the on-line Wikipedia bibliography on Joseph Priestley, which, importantly, is the most up to date (I have subsequently corrected that situation), nor in Robert Schofield book which is considered the authoritative biography on Priestley with an excellent bibliography.  It seems rather odd that a person with such a distinguished career and elaborate corpus of works as Priestley would have a publication missing from his bibliography for more than 210 years after his death, and 221 years after he wrote the article.  

I note, however, that while there was a section on the very subject of the article with the exact same title I found in his book: The History and Present State of Discoveries Relating to Vision, Light, and Colours, London: Printed for J. Johnson, 1772,pp.55-81, there is enough of a difference between the two works that this work should have been recorded as part of his bibliographical legacy. Further, it should be noted that there is a full 21 years difference between the publication dates of the book and the journal article. Finally, it is worth noting that it doesn't make any sense to have excluded it, based solely upon the fact that it appeared in such a prominent British publication with his authorship clearly identified.

One final note about the article, versus its content, is that while the title as stated above is what appears at the head of the magazine article, all subsequent pages of the article carry the banner "On the Invention of Telescopes and Microscopes" [emphasis added].

"The More Elaborate our Means of Communication, the Less we Communicate" J. Priestley


I have often seen the quote offered in the title of this post attributed to Joseph Priestley (1733-1894), the famous 18th century British-American polymath who was the first to report the isolation of the gas Oxygen.  It has never sat right with me.  I have studied much about Joseph Priestley's life and it just didn't seem like there was much in the way of "elaborating" communication that had transpired before or during his lifetime other than the invention of movable type and the printing press in the 15th century.  I had often thought that a more probable candidate for the quote was J(ohn). B(oynton). Priestley (1894-1994), the famous twentieth century British novelist and broadcaster.  He was certainly alive during a period of rapid change in communications technology; as a broadcaster was most certainly aware of communications skills; and, as a novelist he could certainly elaborate upon all this.

 I have found two quotations, one is the title of this post and the other, almost identical, which, at first blush, looks identical, “The more we elaborate our means of communication, the less we communicate”.  The second quote has an additional "we" as the third word.   Of the numerous sources I have found they attribute each of these quotations to either J. B. Priestley, or Joseph Priestley (by the way, most are attributed to Joseph Priestley).  Interestingly, though, the quoters are not unanimous on which is attributable to each person. Not one quoter has actually cited the primary source (by primary source, I mean the actual publication by the respective author). I have found it hard to believe that these two people with almost identical names, each uttered almost identical quotes. I also find it hard to believe that I could not find the actual source of the quotation. 

I am proud to announce that, after a considerable search, I have now found the proper attribution and wording for the quote: “The more we elaborate our means of communication, the less we communicate.”  See Baden Eunson, Communicating in the 21st Century, in reference to Priestley’s Paradox.  The source reference for the quote is J.B. Priestley, Thoughts in the Wilderness,   Heinemann, 1957, p. 201. 

And, of course, the photo above is that of the author of the quote, J. B. Priestley.  May he rest in peace.

Joseph Priestley on Public Television

Wed, Aug 19 at 8 pm, PBS
(Check your local PBS station for broadcast times)

            
Patrick Page as Joseph Priestley                      Patrick Page, Ava Deluca-Verley and Hugo Becker
 as Joseph Priestley, Marie Anne and Antoine Lavoisier

The Mystery of Matter: Search for the Elements is an exciting PBS series about one of the great adventures in the history of science: the long (and continuing) quest to understand what the world is made of—to identify, understand and organize the basic building blocks of matter.

Three hour-long episodes introduce viewers to some of history’s most extraordinary scientists: Joseph Priestley and Antoine Lavoisier, whose discovery of oxygen—and radical interpretation of it—led to the modern science of chemistry; Humphry Davy, who made electricity a powerful new tool in the search for elements; Dmitri Mendeleev, whose Periodic Table brought order to the growing gaggle of elements; Marie Curie, whose groundbreaking research on radioactivity cracked open a window into the atom; Harry Moseley, whose discovery of atomic number redefined the Periodic Table; and Glenn Seaborg, whose discovery of plutonium opened up a whole new realm of elements, still being explored today.

The Mystery of Matter shows us not only what these scientific explorers discovered but also how, using Broadway-caliber actors to reveal the creative process through the scientists’ own words, and conveying their landmark discoveries through re-enactments shot with working replicas of their original lab equipment. Knitting these strands together into a coherent, entertaining whole is host Michael Emerson, a two-time Emmy Award-winning actor.

Mystery of Matter:  Search for the Elements will be shown on PBS on Wednesday, August 19, 2015 from 8PM to 11PM. (3-1 hour shows airing back to back)

The Oldest Tunnel in New York City





There are a variety of types of tunnels that can be built. Primarily they are the cut and fill and the true tunnel.  In the cut and fill method, which is used because it is much cheaper to construct, a trench is dug, the tunnel walls and ceiling are constructed of masonry or other materials, and then the earth is returned to the trench to "bury" the tunnel.  The true tunnel is constructed by literally digging from one end to the other (or, more often, digging from both ends towards the middle). Some true tunnels are dug in dirt, and others through stone. The advantage of stone, many times, is the lack of need for a supporting structure, but the disadvantage, of course, is that the tunnel must be cut from the very strong stone, which makes it much more difficult and time consuming, not to mention the cost.

The oldest true tunnel in NYC for rail traffic, or any kind of traffic, is the Mount Prospect Tunnel in Manhattan, opened in 1837. It now forms the center two tracks of Metro North from 92nd St. to 94th St. under Park Ave. The tunnel north and south of it, and the one-track tunnels on each side of it, were added in 1873-1875, but the Mount Prospect Tunnel was left in place and became part of the larger “Fourth Avenue Improvement”

The following illustration that appeared in the November 14, 1874 issue of the Scientific American shows the ground elevation and other pertinent information on the underground rail line from 42nd St to the Harlem River which was completed in 1875.  Of course, Fourth Avenue, became Park Ave.
In the center frame I have enlarged below you can clearly see that the section between 92nd and 94th Streets is labelled "Rock Tunnel."

Interestingly, the area that the Mount Prospect Tunnel is located is now called the Carnegie Hill area of the upper East side of Manhattan.  That name, Carnegie Hill, became the new name for Mount Prospect after Andrew Carnegie purchased land (1897) and built his residence (1903) at 91st Street and 5th Ave., a few blocks away from the tunnel.

The Atlantic Avenue Tunnel (also referred to as the Cobble Hill Tunnel) in Brooklyn was built in 1844-45 and is touted as the oldest Railway Tunnel in the world, it has been cited that the Mount Prospect Tunnel, while having been built earlier, was originally built for street cars and only converted to be a railway tunnel in the mid 1870s.


Cobble Hill Tunnel


There is a belief that a true tunnel was constructed for the Croton Aqueduct in upper Manhattan which opened in 1842, but that has not been documented as of this writing. Clearly, that tunnel, if it exists, was not for traffic at all, but rather a viaduct for water and appears to be constructed around five years after the Mount Pleasant Tunnel was completed.




The Abrams Universal Sun Compass

I have had an Abrams Universal Sun Compass in my 
collection for quite a few years now.

Shortly after I got my Abrams, about 10 years ago, I 
searched for the company and found that they were still 
in business in Lansing MI.  In the directions that come with 
the device it explains how to adjust the sundial to get a 
correct reading for each day of the year.  I have a pretty 
good understanding of sundials and know why that is the 
case.  There is a plate on the device that has the dates for 
adjusting for the specific days for that specified year.  I was 
wondering if they continued to make additional plates for 
other years.  --- and how many years did they continue 
to produce them.  I called the company and I spoke to 
someone there about the item.  After describing the item 
and what I was looking for she broke out into laughter.  
Nobody had asked her for one of those since the end of WWII.  
I was amazed that she had been there that long and that she 
remembered the item.  Anyway, I got a good laugh out of it 
too.

The following information is contained in a post at 
Collecting Military Compassesand was provided by Ted Brink 
for inclusion here thanks to his permission:

The U.S. Army Sun Compass was produced during WW2 in 
the early 1940s by Abrams Instrument Co. of Lansing, MI, 
designated Model SC-1. In operation, it could determine 
direction accurately by noting the angle of the sun at a known 
time of day. It was designed for daylight use, but could  
navigate at night by orientation to the Polar star, mounted on a 
vehicle in environments where a magnetic compass might not 
work properly, such as inside an aircraft or truck due to the 
metal content or electrical circuits nearby.The exterior of the 
box is painted olive drab and the lid is lettered:

                        C. of E.
                                     U.S.A.
                             SUN COMPASS

The  C. of E. stands for the U.S. Army Corps of Engineers, 
responsible for military compasses and other instruments 
during World War II. 

In World War II the SC-1 was used in the North African 
desert by the Long Range Desert Patrol (the famed Desert 
Rats) and other American, British or Australian units. Other 
uses were in B-24 Liberator bombers and by Army ground 
troops in the PhilippinesIt is reported to have been used 
through the 1970s for polar region expeditions where 
magnetic readings are unreliable or in the Sahara desert.

After Court Battle Equifax Admits that God Exists


As reported in the Canadian Globe and Mail and the New York Daily 
NewsEquifax consents to the existence of God.

"Without a decent credit rating it's tough to borrow for large purchases, as
a Russian-American discovered.  The New Yorker, owner of a business
called Gold Hard Cash, was refused a car loan because credit rating
agency Equifax would not provide financial details on the man.
The problem! God Gazarov was told by Equifax that it "could not process
his name as God."  The suit alleged that an Equfax official told Gazarov it
could not provide him or a lender with his credit file "because it could
not process his name as 'God' and suggested that he should consider
changing it."
After appearing before Brooklyn Federal Magistrate Judge Ramon Reyes,
the two parties to the suit struck an agreement, and Equifax will
now acknowledge God's name.  He will also receive an undisclosed
monetary settlement from the company...
Mr. Gazarov claims his name is not uncommon in Russia, and that he
was named after his grandfather.  Still, he's used to the jokes.  "My
principal in junior High School would walk by me in the cafeteria and 
say, 'Oh my God, there he is.'""
What is also interesting here is that I personally know people by the
name "Jesus."  I don't think the credit reporting agencies have had trouble
with that name.  So, what was the big deal recognizing "God."

Joseph Priestley, the Discoverer of Oxygen




Joseph Priestley, the Discoverer of Oxygen, 1912


Ernest Board, British (1877 - 1934)
Wellcome Library (Wellcome Trust) - London 
Painting - oil on canvas
Height: 61.5 cm (24.21 in.), Width: 91 cm (35.83 in.) 
I just found this painting by Ernest Board of Joseph Priestley. I had not run across it before and I wanted to share it with my readers. It is relatively modern painting of him. Ernest Board was a distinuished British painter of historical subjects and portraits; mural decorator. Born at Worcester, 1877 and was educated in Bristol. Studied art at the Royal College of Art, at the Royal Academy Schools, and later in the studio of Edwin Austin Abbey. Exhibited at the Royal Academy from 1902.  Died on 26th October 1934 aged 57.  Board was a member of the Royal Institute of Oil Painters (R.O.I.) and the Royal West of England Academy (R.W.A.).
