[…] I have placed myself in communication with the Astronomer Royal, for the purpose of considering the steps necessary to be taken to effect the connexion required, between the triangulation of Great Britain and that of Belgium. […] I have also placed myself in communication with General Nerenburger, Director of the Dêpot de la Guerre at Brussels, and have received from him the diagram of the Belgian triangulation, with descriptions of the stations with which it is necessary to connect our triangulation, and we possess a copy of the triangulation of France.
