Paper, 'Supplementary note on the values of the Napierian logarithms of 2, 3, 5, 7, and 10, and of the Modulus of common logarithms' by John Couch Adams
Reference number: PP/10/5
Date: 1886
Description
Adams writes: 'In vol. 27 of the ‘Proceedings of the Royal Society,’ pp. 88—94, I have given the values of the logarithms referred to, and of the Modulus, all carried to 260 places of decimals. These logarithms were derived from the five quantities a, b, c, d, e,which were calculated independently [...] the values found for a, b, c, d, e satisfied [the] equation to 263 places of decimals.Although this proved that the values of the logarithms found in the above paper had been determined with a greater degree of accuracy than was there claimed for them, yet I was not entirely satisfied with the result, since the calculation of the fundamental quantities had been carried to 269 places of decimals, and therefore the [...] equation of condition showed that some errors, which I had not succeeded in tracing, had crept into the calculations so as to vitiate the results beyond the 263rd place of decimals.'
