JOHN HARRISON AND THE DISCOVERY OF LONGITUDEBiblio.com

A 1765 account of John Harrison on discovering longitude at sea using artificial timekeepers from the Annual Register for 1765

1793373234J. Dodsley London 1793. 5th Edition. Hardcover. Very Good Condition. 21 pages. This 1765 article published in The Annual Register provides a detailed account of John Harrison's groundbreaking work in solving the longitude problem at sea through the use of artificial time-keepers. Harrison an English clockmaker developed the marine chronometer a device that allowed sailors to accurately determine their longitude while at sea. His invention was crucial for safe navigation reducing the risk of ships becoming lost or wrecked due to miscalculations. The article outlines the proceedings and debates surrounding Harrison's work including his struggles with the Longitude Board which was reluctant to grant him the full 20000 prize promised under the 1714 Longitude Act. Despite proving the accuracy of his time-keepers Harrison faced political opposition and bureaucratic delays before finally receiving recognition for his achievements. Published at around the same time that Harrison's book of a similar title was published this contemporary 21 page account quotes Harrison extensively and represents the opinions and ideas regarding navigation from the perspective of the time. The whole volume extends to around 600 pages. Bound in modern but not recent brown buckram with a contrasting black leather lettering piece gilt title.

DAVY, HUMPHRY - THE DISCOVERY OF THE ANAESTETHIC EFFECTS OF "LAUGHING GAS"Biblio.com

Athembarkeit des sauerstoffhaltigen Stickgas; aus einem Briefe H.Davy's an Will. Nicholson. Nachricht von einigen merkwürdigen Versuchen Davy's. Aus einem Briefe Humphry Davy's an Will. Nicholson.

179944095Halle Rengerschen Buchhandlung 1799 1800. Without wrappers extracted from "Annalen der Physik. Herausgegeben von Ludwig Wilhelm Gilbert" Bd. 2. p. 483 one page. and Bd. 6 pp. 105-115. Some scattered brownspots. First German translation of Davy's announcement the announcement on 1 page of his discovery of the unusual anaesthetic effects of nitrous oxide which on being inhaled gave rise to a giddy intoxicated feeling. On announcing his discovery he says that he will publish a paper discribing the experiments with the gas later. This is the paper offered here also in the first German version. Both the announcement and the paper were issued in the "Annalen" the same year as they appeared in Nicholson's Journal.The gas was first synthesized by English natural philosopher and chemist Joseph Priestley in 1772 who called it phlogisticated nitrous air."Following Priestley's discovery Humphry Davy of the Pneumatic Institute in Bristol England experimented with the physiological properties of the gas such as its effects upon respiration. He even administered the gas to visitors to the institute and after watching the amusing effects on people who inhaled it coined the term 'laughing gas'! Davy even noted the anaesthetic effects of the gas: "As nitrous oxide in its extensive operation appears capable of destroying physical pain it may probably be used with advantage during surgical operations in which no great effusion of blood takes place".Wikipedia."Davy discovered the anaesthetic properties of nitrous oxide and suggested its use during surgiical operations a suggestion which was not turned to useful account until 1844."Garrison & Morton 5646 not mentioning the announcing of its discovery in 1799. unknown

With titlepage to the volume 1733/1735. Margins of titlepage with a few brownspots. First appearance of these milestone papers in the histroy of electricity in which Dufay explains his discovery of two kinds of electricity and the relation between them attraction and repulsion shocks and sparking and the full recognition of electrostatic repulsion. He formulates the two-fluid theory of electricity. He further showed that "not all bodies can become electrified themselves" by friction and went on to show "that they can all acquire a considerable electrical virtue when the tube of rubbed glass wood metals or liquids are brought near them" provided only that they are insulated by beiing stood on "a support of glass or of sealing-wax".Dufay "TRANSFORMED A COLLECTION OF MISCELLANEOUS WEEDS INTO THE FIRST GARDEN OF EUROPE" Heilbron"Dufay's substantive discoveries - ACR the two electricities shocks and sparking - are but one aspect and perhaps not the most significant of his achievement. His insistence on the impiortence of the subject on the universal character of electricity on the necessity of organizing digesting and regulariizing known facts before grasping new ones all helped to introduce order and professionel standards into the study of electricity at precisely the moment when the accumulation of data began to require them. He foundthe subject a record of often capricious disconnected phenomena the domain of the polymaths textbook writers and prfesional lecturers and left a body of knowledge that invited and rewarded prolonged scrutinity from serious physicists." Heilbron "Electricity in the 17 & 18 Centuries" p. 260.Parkinson "Breakthroughs" 1734 P - Ronalds Library p. 145. - Not in Wheeler Gift Cat. unknown
