A fine and rare Scottish brass mounted mahogany stick barometer with hygrometer William Dobbie to a design by John Russell, Falkirk, circa 1845 The chevron banded case with swan neck pediment and cavetto cornice above arch-glazed door enclosing fine engraved silvered brass scale incorporating HYGROMETER calibrated 0-30 in both directions and annotated DRY/MOIST flanked by fine foliate scroll infill to arch, above arched banner titled BAROMETER and signed W m Dobbie, Falkirk over Vernier scale calibrated in barometric inches and with the usual weather observations positioned to the right of the tube, opposing spirit tube Fahrenheit thermometer similarly labelled THERMOMETER in an arch above to the left, the trunk applied with full-height Corinthian half column with reeded shaft and cast brass capital and base over slightly domed oval cistern cover, 110cm (43.25ins) high excluding finial. Provenance: Private collection, Hampshire (ref. B44); purchased from J.W. Blanchard Limited, Winchester, 14th January 1993 for £1,700. William Dobbie is recorded in Loomes, Brian Watchmakers & Clockmakers of the World, volume 2 as a clock and watchmaker born in Falkirk, 1796 and died 1845. The design of the current lot was devised by the celebrated clock and watch maker John Russell who settled in Falkirk in 1770 in a shop opposite the top of Kirk Wynd. He subsequently became watch maker to the Prince of Wales and died in 1817. The basic design of the current lot was probably developed around 1785 by Russell and appears to have be closely related to that of Benjamin Martin s Triple Weather Glass (an example of which was sold in these rooms in our sale of Mallett: Taking Stock 8th November 2018, lot 109). In his work English BAROMETERS 1680-1860 Nicholas Goodison refers to an excerpt from the Alloa Monthly Advertiser of 7th February 1845 in which it was announced that William Dobbie of Falkirk had just completed two of Russell s splendid royal barometers (now scarce), warranted identical with those made by the original constructor.. from this it would appear that Dobbie was trading on the back of Russell s reputation or perhaps even as his successor. Indeed the current lot would support the latter as the engraving to the register plate is all but identical to an example by Russell illustrated by Goodison on page 230 (plate 157).

Ω A fine Regency mahogany mercury stick barometer with ivory cistern float probably for use in a lighthouse Alexander Adie, Edinburgh, early 19th century The slender figured mahogany case with brass Vernier adjustment screw to top above inset rectangular silvered Vernier scale with canted upper angles and calibrated in barometric inches to right hand margin beneath engraved signature A. Adie, Edinburgh to upper edge , the trunk with visible tube above moulded reeded square section cistern cover with ivory mercury float to right hand side and brass level adjustment screw beneath, 94.5cm (37.25ins) high. Provenance: Private collection, Hampshire (B105); purchased from Michael Sim, Chiselhurst, 12th January 2001 for £2,650 who, in-turn, had acquired the instrument directly from The Trustees of the Northern Lighthouse Commissioners. Alexander Adie is recorded in Goodison, Nicholas English BAROMETERS 1680-1860 as born 1774 and apprenticed to his uncle, the eminent Scottish instrument maker John Miller, in 1789. In 1804 his uncle took him into partnership under the name of Miller and Adie which continued until after Miller's death in 1815. Adie was particularly interested in meteorological instruments and is perhaps best known as the inventor of the Sympiesometer in 1818. In recognition of his work he was elected a Fellow of the Royal Society of Edinburgh in 1819. He was appointed optician to William IV and later Queen Victoria and took one of his sons, John, into partnership in 1835. Two of his other sons set up businesses; Robert in Liverpool and Patrick in London. Unfortunately John Adie was prone to 'fits of despondency' which resulted in him shooting himself in 1857, Alexander Adie died the following year - no doubt expediated by the stress of his son's demise. The current lot appears to be a well made but functional model from Adie's range that has practical refinements such as screw Vernier adjustment to the top of the case and ivory cistern float. Adie is known to have supplied parabolic reflectors for the Northern lighthouse Board as well as barometers which required careful calibration due to their likely use in an elevated position within the lighthouse structure; the provenance provided by Michael Sim would strongly suggest that the current lot was supplied for this purpose.Cites Regulations Please note that this lot (lots marked with the symbol Ω in the printed catalogue) may be subject to CITES regulations when exported from the EU.

A Victorian brass Kew Pattern marine mercury stick barometer configured for use on land Adie and Wedderburn, Edinburgh, second half of the 19th century The cylindrical silvered scale calibrated in barometric inches divided to twentieths and with Vernier slide fitted flush within the tube viewing aperture, the vertical left hand margin signed ADIE & WEDDERBURN, EDINBURGH. the lower margin engraved No. 760, set behind cylindrical glass collar with Vernier adjustment screw and gimballed support over applied mercury tube Fahrenheit scale thermometer to the narrow trunk below, the base with moulded cylindrical iron cistern cover braced within further supporting ring to lower edge, 94cm (37ins) high; applied to original ogee moulded oak wall panel, 105cm (41.25ins) high overall. Provenance: Private collection Hampshire (ref. B27). Alexander Adie is recorded in Banfield, Edwin BAROMETER MAKERS AND RETAILERS 1660-1900 as born 1775 and dying in 1858. Adie was the nephew of John Miller, one of the leading Scottish makers of Scientific Instruments in the 18th century and was apprenticed to him in 1789. In 1804 they formed the partnership of Miller and Adie which continued until the death of John Miller in 1815. Adie continued the business alone specialising in meteorological instruments obtaining a patent in 1818 for his air barometer or sympiesometer. In recognition of this invention he was elected a Fellow of the Royal Society of Edinburgh in 1819. He was appointed optician to William IV and later Queen Victoria after forming a partnership with his son, John, in 1835 to form Adie & Son. John's brother, Richard, moved to Liverpool where he set-up business in Bold Street in 1835. He employed Thomas Wedderburn as a foreman in Edinburgh through whom the current lot was probably supplied. The current lot is made to the pattern of standard marine barometer devised by Patric Adie and John Welsh of the Kew observatory in 1855. Although the instrument is mounted via gimbals the cistern steadying ring and very close proximity of the oak board behind indicates that it was supplied for use on land possibly for a laboratory or meteorological station.

During the 1920 s the firm became E.R. Watts and Son Limited and amalgamated with Adam Hilger Limited to form Hilger and Watts in 1948. The retailer s signature to the back of the current lot indicates that it was supplied through the celebrated firm of watch and marine chronometer makers, James Murray and Company, who moved to Calcutta in around 1880 and traded until 1847.

A fine George III mahogany bayonet-tube mercury stick barometer with large-scale thermometer Nairne and Blunt, London, circa 1780 The caddy moulded case inset with arched silvered Vernier scale calibrated in barometric inches to the right hand margin opposing weather observations to the left, the upper margin signed in a curve Nairne & Blunt, London and the lower edge decorated with an engraved leafy scroll flanked cavetto-shaped angles, the trunk applied with full-height silvered-scale spirit thermometer calibrated in Fahrenheit with scale divided in degrees annotated 0-110 opposing markers inscribed Freezing, Temprate and Blood Heat, over pierced brass bulb shield and circular base applied with half sphere cistern cover incorporating level adjustment screw to underside, 96.5cm (38ins) high. Provenance: Private collection Hampshire (ref. B14); purchased at Mallams, Oxford, June 1982 for £1,050 hammer. The collaboration between Edward Nairne and his former apprentice Thomas Blunt is recorded in Banfield, Edwin BAROMETER MAKERS AND RETAILERS 1660-1900 as established in 1774 and lasting until 1793. Edward Nairne was born in 1726 and apprenticed to the celebrated instrument maker, Matthew Loft, in 1741. Latterly he worked from 20 Cornhill and published numerous booklets on navigational, pneumatic and astronomical instruments. In 1776 Nairne devised a marine barometer with a restriction to the bore of the mercury tube which served to dampen the oscillation of the mercury, he was elected Fellow of the Royal Society in 1776 and died 1806. Thomas Blunt was apprenticed to Edward Nairne in 1760 with whom he formed a loose partnership in 1774, perhaps for mutual convenience as his premises were next door to Nairne's at 22 Cornhill. Blunt designed some of the components for the 'New Barometer' devised by the Portuguese Scientist J.H. Magellan for measuring altitude, and latterly became instrument maker to George III. In 1793 he took his son, also named Thomas, into partnership and subsequently relocated to 136 Minories in 1814, he died in 1822. An almost identical instrument to the current lot (signed by Nairne alone) is illustrated in Banfield, Edwin BAROMETERS, Stick or Cistern tube on page 75.

Ω A rare William IV or early Victorian mahogany and brass mercury portable mountain stick barometer John Newman, London, circa 1835 The slender circular section mahogany case incorporating slot applied with canted silvered brass Vernier scale calibrated in barometric inches from 18 inches to over 32 inches divided into twentieths and annotated 19-32 to right hand margin set behind brass revolving cylindrical shutter and with Vernier adjustment screw to cap, the waist applied with ivory collar engraved NEWMANS IMPROVED PORTABLE IRON CISTERN, 122 REGENT STREET, LONDON opposing annotations CORRECTION FOR CAPACITIES 1/50, NEUTRAL POINT 30.012, CAPILLARY ACTION +.038, TEMPERATURE 66 (degrees), the slightly tapered lower section with inset Fahrenheit mercury thermometer applied to ivory scale over two-part brass cased iron cistern, the lower part turning against a pinned slot engraved with two positions PORTABLE and NOT PORTABLE, 91.5cm (36ins) high; with original leather cylindrical carrying case. Provenance: Private collection, Hampshire (ref. B26). John Frederick Newman‚ is recorded in Banfield, Edwin BAROMETER MAKERS AND RETAILERS as working at 7 and 8 Lisle Street, London, 1816-25 then 122 Regent Street 1827-62 when the business was taken over by Negretti and Zambra. He made standard and portable barometers for James Clark Ross's Antarctic expeditions (1839-1843). In 1851 he exhibited at the Great Exhibition at the Crystal Palace and his meterological station barometers were used throughout the British Empire. Soon after the invention of the barometer in the 17th century it was observed that air pressure decreased with altitude. However, it was not until the latter part of the 18th century before an accurate mathematical relationship between height and drop in air pressure had been devised allowing barometers to be made with the intention of measuring altitude. The two-part iron cistern employed in the current lot was devised by Newman in 1833 to allow safe transport of the instrument. The construction of the cistern incorporates a valve mechanism which essentially shuts off the mercury column from the atmosphere when the lower half of the cylinder is rotated to the PORTABLE position. Newman s instructions for the use of the barometer advises that the instrument should be inverted before the cistern is closed-off presumably to prevent the mercury column from bouncing against the top of the column (potentially breaking the glass) and transported upside-down. Indeed the leather case present with the lot is designed for the instrument to be inverted before insertion. An almost identical instrument to the current lot was purchased by Charles Darwin in 1831 for use on the Beagle voyage (1831-36) and was presented to the Royal Society by the executors of his estate after his death in 1882.Cites Regulations Please note that this lot (lots marked with the symbol Ω in the printed catalogue) may be subject to CITES regulations when exported from the EU.
