22.58  POCKET BAROMETER / ALTIMETER. Absolutely the finest quality 19th century gentleman's pocket barometer with the dual function of serving as an altimeter.  This precision scientific instrument was made by the famed American firm of Queen & Company as hand-engraved on the silvered brass dial "Jas W. Queen & Co., PHILADELPHIA & NEW YORK."  The dial is calibrated in inches of mercury atmospheric pressure from 18 to 31 in amazingly small 5/100th inch increments marked in whole inches.  The reading is indicated by a very delicate blued steel needle.  The periphery of the dial it is marked in feet of altitude from 0 to an amazing 15,000 feet!  To record the observation the knurled outer dial has a small pointer which can be rotated to the proper reading.  The case is solid brass in a gilt finish and has a folding suspension ring at the top.  It rests in its original hinged case with wooden frame, velvet liner and Moroccan leather cover.  The interior retains the original shield-shaped paper label of "ROSENBUSH, Manufacturing Optician 2 Astor House Near Vessey, NEW YORK, Builder of Model Steam Engines, Locomotive, Steamboats & C."  The instrument measures 1 7/8 inches in diameter by 2 ½ inches tall with loop.  The case is 2 ¾ inches tall by 2 ¼ inches wide and an amazing 7/8 inches thick!  Extremely accurate.  We have used it to measure changes in altitude down of 20 feet!   A $500 value. 289

James Queen & Company were noted optical and scientific instrument makers on Chestnut Street in Philadelphia, with a branch office in New York City.  It was begun in 1853 by its founder James W. Queen, maker of optical and philosophical scientific instruments.  In 1859 Queen took Samuel Fox as a partner and the company grew rapidly.  Queen retired in 1879 and Fox continued the business under the name James W. Queen & Co., continuing until 1893 when it was incorporated as Queen & Co.  In 1912 the company was reorganized as the Queen-Gray Co.   The company was in business under this name until 1925.

22.57  ANEROID BAROMETER.   Finest quality 19th century aneroid barometer made by the esteemed Paris maker Pierre (alternatively Paul)  Naudet as indicted by the maker's mark "PNHB" (Paul Naudet Holostric Barometer) on the bottom of the silvered brass dial.  It is additionally stamped on the back of solid brass case "PNHB" within a circle.  The open face dial with brass rim showcases the amazing mechanism within.  Through a series of complicated linkages atmospheric pressure activates the mechanical bellows transmitting movement to the lovely blued steel indicator needle with amazing accuracy!  The reading is recorded on the dial calibrated in inches of atmospheric pressure form 24 to 31 in 2/100ths inches marked by tenths.  The dial bears the standard weather indications "STORMY, RAIN CHANGE, FAIR and VERY DRY.  The top of the dial is marked "Made In France" and the bottom is marked "Holosteric PNHB Barometer."  To record the previous reading, a brass set needle riding above the set needle is attached to a knurled knob rove through the beveled glass crystal.  This barometer has the unusual dual feature of being hung by the suspension loop at the top or by resting on a shelf or desk with its 2 turned brass feet.  5 ¼ inches in diameter by 2 1/8 inches deep.  Excellent original condition.  All surfaces retain their original orange lacquer showing expected age, but no damage or wear.  The barometer function is lively and very accurate.  395

The first practical aneroid ("without liquid") barometer is generally attributed to Parisian, Lucien Vidie in 1843, who was awarded an English patent for his device in 1844.  Vidie's patent rights expired in 1859, allowing other makers to produce instruments.  The most successful makers in France were Naudet, Hulot & Cie, who reportedly made 20,000 instruments between 1861 and 1866.  1

Another reference to the firm was made by Middleton who states, "...there were several makers soon after the patent expired in 1859, the most successful being Naudet, Hulot, & Cie.  According to Le Roux they made 20,000 aneroid barometers between 1861 and 1866.  They called them baromètres holostériques...  references occur in the continental literature to Naudet barometers and to holostric barometers for the rest of the nineteenth century.  They acquired a great reputation and were widely imitated." 2  Middleton goes on to state,  "For many purposes aneroids continued to be made - and are indeed still made - of a form very like that arrived at by Naudet, Hulot & Cie about 1860." 3   In the Appendix is an entry for a barometer held in the collection of the Smithsonian Institution, Washington, D.C.  It reads, "230,002 A "Holosteric  Barometer- Compensated, "made by Naudet & Co. Marked on the back of the case, U.S. Signal Service" 4 indicating manufacture around the time of the First World War.

Surprisingly, little is written about the innovative and prolific Paris aneroid barometer maker, Pierre (alternatively "Paul) Naudet, although it is known that his firm was begun in 1861 and  continued producing aneroid barometers into the 1930's.

The dating and meaning of the markings HBPN (alternatively PNHB) are less clear.  An entry for a barometer sold on eBay indicates the markings refer to "Hulot, Pertius & Naudet, Paris, barometer makers in the 1930's.  However Andy Demeter, writing about the history of the Chelsea Clock Company notes, "With the possible exception of recording barometers, Chelsea did not assemble holosteric or aneroid movements for their barometers preferring to purchase them from the legendary French maker, Pierre (alternatively Paul) Naudet.  His firm's trademark is typically found in a circle on these early barometer dials with the letters "HBPN" as an abbreviation for "Holosteric Barometer, Pierre Naudet."   On page 220 a barometer dial is pictured with the caption, "1909 Pierre Naudet barometer."

22.40   BAROGRAPH.  Superb quality, third quarter 19th century British recording barometer by one of the most famous makers of the era, “LENNIE EDINBURGH” as engraved on the bedplate.  This precision scientific instrument is as lovely as it is accurate.  The complex solid brass mechanism is gold washed.  It consists of a stack of 8 flexible aneroid bellows attached to a linkage which transfers motion to an inking stylus at the end of a long metal trace.   The bellows expand and contract with changes in atmospheric pressure, the extent of which are measured on the revolving clockwork drum.  To set the reading a knurled thumbscrew is at the top of the cross bar of the support columns.  A long arm attached to a knurled knob on the bedplate allows the trace to be disconnected from the drum when not in use.  The drum is encompassed by an interchangeable paper chart calibrated in barometric inches of mercury from 28 to 31 in 5/100th increments on the a axis.  The x axis is calibrated in days of the week divided by 2 hour intervals.   The bottom of the chart is signed “LENNINE 40 PRINCESS STREET EDINB.”  Inside the drum a  jeweled clockwork with built-in winding key revolves the drum precisely once a week to produce a continuous and accurate record of atmospheric changes.   These observations were important for the British Meteorological Office (the “Met” formed in 1854) to help forecast weather at sea for the safety of seamen.  To these ends a large number of blank and actual inked charts are contained in a drawer below.  The mechanism is housed in a handsome splined solid mahogany case with thick beveled glass on all 5 sides.  An articulated brass arm allows the case to be opened and held in place while servicing.  A small bottle of special red recording ink is held in its receptacle.  The entire unit measures 14 ½ inches long by 9 inches wide and 8 3/8 inches tall.  Outstanding original condition.  The clockwork has just been fully serviced by a professional watchmaker.  1495

Eliza Lennie, widow of James Lennie, worked as an optical instrument maker at 40 Princess Street, Edinburgh, Scotland from 1857-1901.  Her husband, James Lennie, began the firm as an optical instrument maker in 1840 until his death, at which time his wife took over the business and traded under the name.  (Edwin Banfield, “Barometer Makers and Retailers 16660-1900,” 1991, Baros Books, Trowbridge, Wiltshire.)

22.06  ANTIQUE BAROGRAPH.  Extraordinary, scientific grade turn-of-the-last-century weather instrument made by the well known English makers “Short & Mason, London.”  This lovely, fully functional instrument embodies the long-standing British penchant for form and function.  As such, the precision mechanism with gilded brass works and hardwood housing is a thing of beauty.  It employs 12 evacuated silvered bellows connected with a complex linkage system to a stylus holding an inking pen.  The linkage is all brass with steel pivots as mounted to the gilded brass bedplate.  It is decoratively-engraved with its makers, “Short & Mason London.”  The quill-type pen records a trace on the revolving drum.  A lever mounted on the front of the bedplate allows the pen to be lifted from the drum when not in use.  The brass drum is turned by a jeweled clockwork mechanism which runs for 8 days on a single wind, making one revolution per week.  To these ends there is a Fast/Slow adjustment feature under the removable brass cover and a separate winding key.  The interchangeable chart paper graph encompassing the drum is marked from 28 to 31 inches of barometric pressure in 1/10th increments on the “y” axis and is marked Monday through Sunday in 2 hour increments on the “x” axis.  The glazed wooden case is made of rich mahogany with all brass fittings and is supported on 4 wooden feet.  The sturdy scalloped base is complete with pull-out drawer containing 2 compartments.  The forward compartment is filled with original, unused gummed graph charts.  In addition there is an original pamphlet reading “S and M STORMGRAPH RECORDING BAROMETER, Directions For Use.”  The second compartment is for storing recorded charts.  The upper removable case contains its original old glass on all 5 sides.   This instrument measures 14 3/8 inches long by 8 ½ inches wide and 8 1/2 inches high.  Complete with the original ink vile with ground glass stopper and contents!  The entire presentation is in an outstanding state of original preservation, fully functional (the clock keeps good time) and is complete with at least 20 spare recording charts in pristine original condition.  Price Request Special Packaging

22.09  WEATHER GLASS.   Authentic hand-blown glass weather instrument known as a weather glass, storm glass or thunder glass, as found in the homes of sea captains from the 17th through the19th centuries.  This exacting copy consists of a one piece glass vial with a hanging eye at the top, a curved swan’s neck spout, and terminates in a bulbous glass bottom.   It is complete with a hand-wrought hanging bracket of copper and brass.  In use the glass is partially filled with water so that the level can be seen within the spout.  Weather changes accompanied by varying atmospheric pressure are evident in the rise and fall of the water level in the spout.  The hanging bracket measures 12 inches tall overall and the glass is 9 inches tall and 3 ½ inches wide.  Perfect condition.  49

Bert Bolle in “Barometers,” 1982, Argus Books, Watford, Herts, England discusses the Thunder glass or “donderglas” stating, “The title of “weather glass” is more apt than “barometer” in the context of the instrument shown.  A barometer is a measuring instrument, as such, has a scale; a thunder glass does not have a scale.  Therefore the term “weather glass” is more suitable for this, nonetheless, decorative antique."

"In the illustration, one can see that the glass is hung from a small hole at the top and is filled with liquid.  This can be water with a dye if desired.  The instrument, about 10 inches high, functions on the principle that variation in air pressure will cause fluctuation in the water level in the spout.  Without a doubt, this instrument is only partly reliable as it is greatly influenced by variations in ambient temperature.  However, if the thunder glass is hung in a place where variations in temperature are minimized, it is an excellent indicator of variations in air pressure."

"Thunder glasses were characteristically Dutch and production got under way sometime in the early 17th century."
This example comes complete with the original instructions printed when we commissioned an old-school glass blower to make a few of these instruments in 1983.  Since then they have been in storage for more than 30 years!

22.13  BAROMETER / ALTIMETER.  Large, extra nice late 19th century English gentleman’s traveling barometer with the dual function of being an altimeter. This unusually large portable instrument is in the form of a pocket watch with bow and retains its bright brass finish.  The silvered brass dial is hand-engraved.  It is calibrated from 25.5 to 31 inches of barometric pressure, divided down to 2/100ths of an inch.  It is marked “Compensated” and “Made in England”   The outer rim of the dial is marked in “FEET” from 0 to 5,000 divided down to amazing 20 foot increments!  To set and record a reading the rim revolves.  This is provided with pinpoint accuracy by the extremely fine steel indicator needle which is little more than a hair’s width in diameter!  This instrument is complete within its silk and satin-lined, hinged wooden case with Moroccan leather cover.  A small spring-loaded lever with brass button latch secures the case when closed.  3 ¼ inches in diameter and 1 ¼  inches thick.  The dial itself measures 2 ½  inches across.  Fully functional and accurate.  595
