Geology of Ireland--Griffith, Sir Richard John. A general map of Ireland to accompany the report of the railway commissioners shewing the principal physical features and geological structure of the country. Constructed in 1836 and engraved in 1837-8. Dublin: Hodges & Smith: London: James Gardner, [1839], first edition, hand-coloured lithographed map on 6 sheets (each sheet 65 x 79.5cm), dissected and backed on linen, edged in red silk, cloth chemise, original diced calf slipcase lettered in gilt on spine . Note: A fine copy of the Sir Richard Griffith's geological map of Ireland on the quarter inch scale. In Ireland the map possesses the same pioneer status as is held in England and Wales by William Smith's map (1815) and in Scotland by John Macculoch's map (1836). The Irish geologist Richard Griffith (1784-1878) a child prodigy, was unanimously elected to the Royal Society of Edinburgh at 23 years of age, elected a member of the newly established Geological Society of London in 1808 and in 1812 was elected professor of geology and mining engineer to the Royal Dublin Society. In 1827 he started his monumental work on the valuations of Ireland. In his work Sheets of Many Colours: the Mapping of Ireland's Rocks Davies states "In its edition of 1839 Griffith's map represents a fine acheivement; in its edition of 1855 it is on every count - cartographic, aesthetic, and geological - a truly superb map." For his geological map and other services to science Griffith was awarded the Wollaston medal by the Geological Society in 1854. Presentation copy, inscribed on cloth chemise "Sent to me from London by Mr Drummond Under Secretary, July 1840", the recipient's name erased. Thomas Drummond (1835-1840), The Under-Secretary for Ireland, the permanent head of the British administration in Ireland prior to the establishment of the Irish Free State in 1922. Rare: only three copies of the 1839 edition found in the online catalogues of Copac or KVK: N.L.S. (2 sheets only, of 6), Cambridge and Trinity College, Dublin.

A storm glass and thermometer on walnut stand J. Blount Thomas & Co, Southampton and Negretti & Zambra, London, circa 1880. The cylindrical glass canister engraved FAIR, Change, STORMY from top to bottom and signed J. Blount Thomas & Co. Southampton to left-hand side beneath brass cap and suspension loop, mounted onto wooden stand beside Fahrenheit scale mercury thermometer with ceramic scale signed NEGRETTI & ZAMBRA, SCIENTIFIC INSTRUMENT MAKERS, LONDON, 38cm high overall, B.C. Ref. 308; and two wall mounted storm tubes, the first inscribed JOHN DAVIS & CO. FITZROY WORKS, LONDON S.E to the beech backboard and with Fahrenheit scale alcohol thermometer, 21.5cm high overall, B.C.

All illustrated in Banfield, Edwin BAROMETERS Aneroid and Barographs pages 144-146. The exact date or by whom the storm glass was invented is unknown but Admiral Fitzroy in his Weather Book of 1863 suggests that they were introduced around 1750. The glass cylinders contain crystals of potassium nitrate and ammonium chloride in an alcohol solution of camphor with some distilled water. In fine weather the crystals are supposed to gather at the bottom of the tube and move upwards prior to and during stormy weather. However, as these instruments were prone to responding to changes in other conditions such as temperature and exposure to sunlight, they were never considered particularly reliable.
