Pocket barometer having 1½” silvered and engraved dial, barometric scale with a range from 24 – 31 inches of mercury, outer altitude scale with arrange from 0 – 7,000 feet, the upper dial with standard meteorological terms, “Rain,” “Change,” “Fair” and “Compensated,” rotating bezel with fine index, fine blued steel pointer set under low iron bevelled glass. 1” capsule driven movement of conventional design, contained within a low barrel form case with knurled ring design, the verso with compensation port to 9 o’clock. Case extension and suspension ring.
The compass with ¾” silvered card marked with cardinals and intercardinals, bar needle set under jewelled pivot, bevelled low iron glass, low drum form case with extension and integral transit lock on a button. Suspension ring. The thermometer with twin scales in Centigrade and Fahrenheit with ranges from 0 – 50 and 20 – 130 degrees respectively, and indicating freezing point and blood temperature.
The whole contained within its original travelling fold-opening black leather over wood and maroon velvet lined case, with red silk linings to the compass and thermometer seatings, gilt brass catch and keeper, fold-out picture fame style stand to rear.
The barometer slightly unusual in its diameter, smaller than most, serviced and calibrated, it has good sensitivity and progression; barometer dial with minor marks, the case retaining virtually all its original lacquer. The compass swinging freely and easily finding north, transit lock functioning correctly; the compass similarly retaining almost all its original lacquer, the silvered card and reflector ring clean and crisp. The thermometer in good order with an unbroken thread and reading correctly – clean and crisp overall. The travelling case with abrasions and marks generally to the exterior, the interior velvet in poor condition with substantial losses due to sunlight exposure – this is very common as many of these instruments were kept permanently open on display.
This is really rather a charming and attractive item, undeniably manufactured in the later middle 19th century. The maker is unclear but study of the barometer movement might suggest Louis Casella, London. It is possible that the compass or indeed the barometer might be a contemporary replacement as they do not perfectly match in design detail but, this notwithstanding, this pocket barometer travel compendium is a worthy piece and would make a lovely gift.
