<p>This volume and its partner [<a href='/view/MS-RGO-00014-00039/1'>RGO 14/39</a>] give an idea of the breadth and variety of correspondence received by the Board of Longitude from the 1780s. Both volumes show the way in which the Commissioners came to be seen by applicants as a general focus for scientific inventions. Some of these were to do with navigation but others were purely mathematical. Indeed, one correspondent, <a href='/search?keyword=Joseph%20Shee'>Joseph Shee</a>, enquired of the Board whether perpetual motion came within the remit of their responsibilities. <a href='/search?keyword=Captain%20Hurd'>Captain Hurd</a>'s reply, as secretary, was that it did not. Clearly this did not stop the many other contributors whose schemes make up the entire of Volume 54 [<a href='/view/MS-RGO-00014-00054/1'>RGO 14/54</a>]. The titling of the volume as containing 'impracticable schemes' combined with the title pages [<a href='' onclick='store.loadPage(301);return false;'>430r</a>] describing schemes as 'wild' shows how such schemes were viewed by the nineteenth-century organisers of the Board of Longitude archive. Contemporary notes on the back of letters show that the Commissioners were generally in accord. Astronomer Royal <a href='/search?keyword=Nevil%20Maskelyne'>Nevil Maskelyne</a> [<a target='_blank' class='externalLink' href='http://collections.rmg.co.uk/collections/objects/379043.html'><img title="Link to RMG" alt='NMM icon' class='nmm_icon' src='/images/general/nmm_small.png'/></a>] noted on some that 'This letter does not deserve the attention of the Board of Longitude' [<a href='' onclick='store.loadPage(409);return false;'>482r</a>]. Likewise, the secretary <a href='/search?keyword=William%20Wales'>William Wales</a> commented 'This method is not deserving of the Board's attention' [<a href='' onclick='store.loadPage(299);return false;'>428r</a>]. However, proposers in this volume also feature in 'sensible' proposals in others. Notable here is the 'Solometer' proposed by <a href='/search?keyword=William%20Lester'>William Lester</a> in 1820-1. This volume includes an illustration and discussion [<a href='' onclick='store.loadPage(126);return false;'>345r</a>] of Lester's invention. Much of the related correspondence is now in RGO 14/12 [<a href='/view/MS-RGO-00014-00012/5'>RGO 14/12:297r</a>].</p> <p>The attitude of all the proposers, on the other hand, might be summed up by a statement in a letter [<a href='' onclick='store.loadPage(89);return false;'>328r</a>] from <a href='/search?keyword=Richard%20Judson'>Richard Judson</a> in 1805, that 'here are several ways of finding the Longitude some of them certainly will be right.' This volume includes the usual range of proposals from observation and new invented instruments, including diagrams and tables of calculation. Notably proposals from both William Lester and <a href='/search?keyword=Charles%20Moody'>Charles Moody</a> show that they also sent model instruments to the Board. What is particularly interesting in this volume, is the different levels of knowledge which correspondents show regarding the terms of the longitude acts. William Ross wrote [<a href='' onclick='store.loadPage(275);return false;'>416r</a>] in 1806 that he had seen the terms reproduced in the <i>Nautical Almanac</i> , hopefully proposing that, like all mathematical teachers, he could find the difference of longitude on the globe, and that this seemed to be for what the act asked. By contrast, Joseph Shee's correspondence [<a href='' onclick='store.loadPage(335);return false;'>446r</a>] shows that he thought he would become a Commissioner of Longitude when the Board approved of his proposal, and <a href='/search?keyword=Alexander%20Winter'>Alexander Winter</a> had heard [<a href='' onclick='store.loadPage(433);return false;'>496</a>] that the reward on offer was one million pounds. A similarly interesting contrast is visible in how proposers address the Board. A number show diffidence in addressing unsolicited letters to gentlemen with whom they are not acquainted, while <a href='/search?keyword=de%20Sanctis'>de Sanctis</a> presumed on a social acquaintance with <a href='/search?keyword=Thomas%20Young'>Thomas Young</a> (see portrait [<a target='_blank' class='externalLink' href='http://www.npg.org.uk/collections/search/portrait/mw81992/Thomas-Young?LinkID=mp04986&role=sit&rNo=5'>link</a>] at National Portrait Gallery) and <a href='/search?keyword=William%20Hyde%20Wollaston'>William Hyde Wollaston</a> [<a target='_blank' class='externalLink' href='http://collections.rmg.co.uk/collections/objects/136781.html'><img title="Link to RMG" alt='NMM icon' class='nmm_icon' src='/images/general/nmm_small.png'/></a>] to send a number of discussions and even some Latin odes [<a href='' onclick='store.loadPage(307);return false;'>433r</a>] addressed to them as 'the Scientific Protectors of the British Navigation, as Castor and Pollux were of the old Ships of Greece and Rome.'</p> <p>Katy Barrett<br />History and Philosophy of Science<br />University of Cambridge<br /> </p>
