Pub Title:
An account of the trigonometrical operation, whereby the distance between the meridians of the observatories of Greenwich and Paris has been determined By Major-General William Roy, F.R.S. and A.S. From the Philosophical Transactions. (London: 1790).
Pub Note:
First separate edition, Roy's last paper on the Triangulation of South-east England, which connected to the French network made by Jean Dominique Cassini, resolved the dispute over the difference in longitude between the Paris and Greenwich observatories. It also laid the foundation for the whole triangulation of England and creation of Ordnance Survey. This paper was read before the Royal Society on 25, February 1790 and Roy died in April later that year. His most important legacy was the establishment of Ordnance Survey. This work published win 162 pages, with 11 folded plates and maps. Bound in marbled boards covers, leather spine with gilt tooled raised band with "Roy's Account" stamped in gilt.
