Greenough no.11. No key, but the geological colouring is quite broad and simple, with rough lines indicating the extent of the chalk. Scale-1:250,000. Dissected on cloth. |
| Administrative History | The majority of the references cited date from before 1817, including: Sir George Stewart Mackenzie's 'Travels in the island of Iceland, during the summer of the year MDCCCX' (1811), during which he was accompanied by Henry Holland and Richard Bright; the surveys of Captain Francis Beaufort, RN ; Encyclopedia Britannica [nd]; 'Neptune Francais', ?1693 [atlas of sea charts owned by Greenough, now held by RGS]; 'Seatorch', which may be J T Serres' 'The Little Sea-Torch or True Guide for Coasting Pilots, along the Coasts of England, Ireland, France, Spain, Portugal, Italy, and Sicily, &c' (1801) [another Greenough volume, also held by the RGS]; information from William Thomas Horner Fox Strangways, February 1817.
There is one reference, written in pencil which seems to cite Carl Vogt's 'Lehrbuch der Geologie und Petrefactenkunde...' (1846-1847) which may indicate that the map was reworked at a later date. |
| CustodialHistory | Thomas Sheppard gives this map a date of 1835, possibly connected to the apparent lack of Roderick Murchison's & Adam Sedgwick's Silurian and Cambrian systems respectively. |
