| Description | He has been on a visit to 'Chrysal's enterprise' at St.Fillans. Shaw cannot give a complete answer aboiut [George Gabriel] Stokes's letters of 1879 but he thinks the results might be the bridled anemometer at Holyhead. He gives a reference to the only description of it he knows, stating that the apparatus has been in use since 1880 and Munro made it. He thinks he might find entries in minutes of Council, but he does not have them to hand. The Holyhead apparatus has no direction reading, the set of horizontal plane cups being replaced by cups in different planes, which he illustrates. He believes that Stokes himself might have altered the design, with Munro; it might be better to print a description of the anemometer as originally erected. Larmor can see the apparatus at any time in Holyhead, and Shaw suggests an accompanying note. When they were discussing arrangements for the Cambridge Observatory last year, Shaw obtained permission to move the anemometer from Holyhead to the Observatory. He has not had time to arrange this, and thinks it may not be suitable for areas of light wind. Shaw hoped to spend time writing the history of the [Meteorological] Office for the past fifty years, before leaving for the eclipse. |
