RH says..... I have not been able to find out who Mr Buller and Mr Gray were, or anything about the former's navigational method. However, this entry is a good illustration of the Royal Observatory's role as one of the Admiralty's scientific departments, testing equipment and commenting on navigational methods. The ROG had, of course, been founded "for perfecting the art of Navigation".
