| Description | Hills is glad that the question of the measurement of British arcs has resurfaced. The connection with the continent was made in 1864, he thinks, but owing to the inferiority of the British triangulation it has never been worth co-ordination for geodetic discussion. He notes other aspects of the history of triangulation and he sends another copy of his and Close's memorandum. Discussion at the Ordnance Survey may have been on the wrong tack, since they were under the impression that only the British arc from the Shetlands to the Isle of Wight would be required and that a large portion of the original triangulation would have to be re-observed. It should be made clear to the Treasury that only a fraction of the work would need to be redone. |
