Copy of a letter from Joseph Shee of Seville to his son Joseph Shee (Junior) in Gibraltar, 1813-10-02 - 1813-10-06
Concerning his invention of an instrument for the discovery of 'the fixed point' of both latitude and longitude. The letter includes a petition which he asks Joseph to send on, requesting from the Government 'every privilege reserved to English meritorious subjects'. It also includes details of the instrument known as 'Shee's machine' or 'the instrument of fixed point' and establishes Shee as its inventor.
Establishing Shee as the inventor of an instrument for the discovery of 'the fixed point' of both latitude and longitude, and originally enclosing a copy of a letter to his son in which Shee outlines the privileges he sought in return for this discovery [RGO 14/40: 445]. He states his desire to be made a member of the Board of Longitude and asks that the Board not give credit to any other claims for the discovery of longitude before examining his work.
Defending the relevance of his work on 'the fixed point' to the search for longitude.
Explaining that he had now found longitude by means of two methods, both founded on the 'centre of infallibility', one of which involved using a star dial of his own invention.
Two copies of a letter in which Shee remarks that he had not received an answer to his letters on longitude, but had nonetheless continued in his work, as he was resolved 'not to deprive man of the wonderful effects' his discovery would have.
